Our Company

We are a leading provider of a broad array of highly engineered products for the wireless communications and electric transmission and distribution ("T&D") infrastructure markets, based on management's estimates of tower and pole revenues in the industries in which we operate. These products, including towers, monopoles, transmission structures, wood pole equivalents, shelters and ancillary components, are critical to the development, expansion and maintenance of both wireless communications networks and electric T&D systems. Wireless communications infrastructure products enable carriers to meet growing consumer demands for increased network coverage and capacity and improved signal quality. Electric T&D infrastructure products are critical components for the upgrade and expansion of the aging electric T&D grid in the United States. In the last 19 years, we have grown from a regional provider of towers for the wireless communications market into a national provider of a diversified suite of products for both the wireless communications and electric T&D infrastructure markets. From fiscal 2005 to fiscal 2010, our revenue has increased from $93.5 million to $255.3 million, our net income (loss) has decreased from net income of $13.4 million to a net loss of $7.5 million, and our adjusted EBITDA (as defined in note 2 to our Summary Consolidated Financial Data beginning on page 9) has increased from $14.2 million to $20.2 million. The chart below illustrates our revenue by reportable segment in fiscal 2005 and fiscal 2010:


FY2005—$93.5 Million in Revenue		FY2010—$255.3 Million in Revenue

We have grown both organically and through acquisitions. Our growth has resulted from: (i) our development of our proprietary end-to-end engineering, design and quoting system for wireless towers, which we believe gives us a significant cost and quality advantage over many of our competitors; (ii) our successful entry into the electric T&D infrastructure market, aided by the hiring of industry experts and seasoned professionals and the construction of our purpose-built, state-of-the-art manufacturing and galvanizing facility in Alvarado, Texas; and (iii) our acquisition of CellXion, LLC in 2007, which has enabled us to expand our wireless communications infrastructure segment to include

Table of Contents

the shelters critical to the protection of valuable wireless communications equipment. These primary growth drivers have enabled us to achieve year-over-year revenue growth in 14 of the last 17 years.

Our wireless communications infrastructure reportable segment supplies a broad suite of wireless communications infrastructure products, including guyed and self-supporting towers, monopoles, shelters for wireless communications equipment and ancillary components, as well as complementary services, including engineering, equipment integration, construction, third-party logistics and turnkey project management, all of which enable us to serve as a one-stop shop for our wireless communications infrastructure customers. Our products and services enable wireless network providers to meet the growing demands for higher-quality services, increased coverage and capacity and improved signal quality created by increasing data usage and wireless device penetration and the advent of third- and fourth-generation, or 3G and 4G, wireless technology. We serve a diverse base of blue-chip customers, including leading wireless service providers such as AT&T, Sprint, T-Mobile and Verizon, large-scale tower management companies such as American Tower Corporation, Crown Castle International Corp. and SBA Communications Corporation, and federal, state and local governments.

Key Industry Trends

Wireless Communications Infrastructure

•: Increasing Wireless Device Penetration—According to the 2011 ICT Market Review and Forecast published by the Telecommunications Industry Association, or TIA, wireless penetration (defined as the number of wireless subscriptions as a percentage of the total population) in the United States was approximately 94% in 2010 and is expected to reach 99.9% by 2014. Since wireless device capability now extends significantly beyond voice service, consumers are increasingly likely to upgrade to the next generation of wireless data devices, including smart phones, tablets, readers, mediapads, netbooks, smartbooks, digital cameras and other devices. According to TIA, U.S. smart phone sales increased from 1.8 million units in 2003 to 54.0 million units in 2010, representing a compound annual growth rate of 62.6%. TIA reports that the percentage of wireless device unit sales represented by smart phones increased from 21.8% in 2008 to 37.5% in 2010, and is projected to reach 54.9% by 2014. Since TIA expects unit sales of all wireless devices to increase by a compound annual growth rate of 3.7% from 2011 to 2014 and the percentage of wireless device unit sales represented by smart phones is also increasing, there is considerable room for additional growth of smart phone sales. TIA reports that smart phone sales are expected to be 91.4 million units per year by 2014, representing a projected compound annual growth rate of 14.1% from 2010. Cell phones continue to replace traditional wireline communications services as the primary communication device for end users in the United States, as 26.6% of U.S. households had only cell phones as of June 2010, an increase from just 13.6% in June 2007, according to publicly available industry reports. As the wireless penetration level continues to increase and smart phones and other wireless devices, including tablets, continue to displace and supplement

Table of Contents

traditional wireline communications services, we believe the demand for towers, monopoles, shelters and other products and services that we provide will also increase.

•: Increasing Data Usage—Wireless data is one of the largest growth drivers for wireless carriers. According to TIA, spending for wireless data services increased from $6.9 billion in 2005 to $54.0 billion in 2010, a 50.9% compound annual growth rate. TIA expects spending on wireless data services to grow to $107.0 billion in 2014, a compound annual growth rate of 18.6% from 2010. According to publicly available industry reports, the first wireless communications networks were primarily built for voice and short messaging services. As TIA notes, the throughput of those networks was not designed to provide the bandwidth required for 3G and 4G wireless data devices and their high-bandwidth, data-intensive applications, such as enhanced video and picture sharing, fast web browsing, streaming video and large file downloading. Further, TIA reports that these new wireless data devices and the demand for high-bandwidth, data-intensive applications and services have already created a significant strain on network capacity. In order to increase network capacity, we believe carriers will add cell sites and towers, which we expect will require considerable capital expenditures for wireless infrastructure.
•: Consumer Demand for Higher Quality of Service—According to publicly available industry sources, continued growth of the wireless communications infrastructure industry is driven in part by consumer demand for quality of service, which is primarily a function of coverage and capacity. As TIA notes, there is an increased need to meet consumer demand for improved quality of service, and to enable wireless carriers to distinguish themselves from one another, which we believe will cause carriers to continue to invest in wireless network infrastructure to expand wireless network coverage areas and enhance the capacity of existing infrastructure, which we expect will result in increased demand for our products.
•: Continued Build-out of Advanced Networks—According to TIA, increased wireless data usage and wireless device penetration and rising demand for higher quality of service have spurred the development of 3G and 4G wireless networks, which are expected to increase network infrastructure requirements. Additionally, TIA reports that between 2001 and 2010, the number of cell sites in the United States increased from 127,540 to 273,000 and is expected to continue to grow at a compound annual growth rate of 9.1% from 2010 to 2014, reaching 387,000 cell sites. As a result, we believe the demand for towers, monopoles, shelters and other products that we provide will increase.

Electric T&D Infrastructure

•: Increasing Demand for Reliable Power Delivery—The U.S. Department of Energy's Energy Information Administration, or EIA, forecasts that total electricity use in the United States will increase by approximately 25% from 2008 to 2035. According to publicly available industry reports, this increase is driven by population growth, economic expansion, increasing dependence on computing power throughout the economy and the proliferation of electrical devices in the home. For example, a U.S. Environmental Agency ENERGY STAR Program report to Congress concluded that servers and data centers have become one of the largest users of electricity in the United States. According to this report, power consumption by servers and data centers doubled between 2000 and 2006, and U.S. energy consumption by servers and data centers could nearly double again by 2011 according to estimates by the U.S. Environmental Protection Agency. Based on studies conducted by the American Society of Civil Engineers and the U.S. Department of Energy, or the DOE, we believe that this increase in electricity demand will require considerable investment in electric T&D infrastructure to improve the efficiency of existing systems and expand the overall electric power grid.

Table of Contents

•: Aging and Unreliable Electric Power Infrastructure—According to the DOE, the U.S. electric infrastructure system is aging, inefficient, congested and incapable of meeting future U.S. energy needs without operational changes and substantial capital investment over the next several decades. According to the Edison Electric Institute, or EEI, investment in electric transmission infrastructure declined from 1980 to 1999, during which time, according to the U.S. Energy Information Administration, electricity consumption increased by approximately 58%, resulting in increased grid congestion and power outages. These outages can be severe and highly disruptive, such as the rolling blackouts in California during 2001 and the August 2003 blackout that disrupted electricity service for 50 million customers in the United States and Canada. According to EEI, members of EEI, which represent approximately 70% of the U.S. electric power industry, were expected to spend $11.1 billion annually on transmission projects in 2010, up from $5.7 billion in 2004.
•: Increased Focus on Wind and Other Renewable Power Sources—We believe that the increased focus on renewable energy also should promote growth in electric T&D investment as transmission infrastructure must be developed to reliably integrate renewable energy sources like wind, solar, geothermal, hydrogen and biomass with the broader electric power grid. The North American Electric Reliability Corporation, or NERC, and EEI note that, since most sources of renewable power are located far from urban demand centers, substantial infrastructure investments are expected to be required to transport electricity to the grid. According to publicly available industry reports, global spending on renewable energy projects is projected to increase from $55.0 billion in 2006 to $325.1 billion by 2018. According to publicly available industry sources, renewable power development also benefits from strong regulatory support, with 29 states, the District of Columbia and Puerto Rico adopting mandatory renewable portfolio standards, or RPS, policies, seven other states enacting non-binding RPS-like goals and the U.S. Congress evaluating national renewable generation targets.
•: Other Legislative Developments—The U.S. government has directed significant efforts towards the modernization and improvement of the U.S. electric grid. These legislative developments continue to promote growth in electric T&D infrastructure investment by encouraging electricity providers to expand capacity and relieve grid congestion. The Energy Policy Act of 2005 established mandatory grid reliability standards and created incentives to increase electric T&D infrastructure investments. The American Recovery and Reinvestment Act of 2009 also has provided funding for modernizing electric T&D infrastructure, with $4.5 billion allocated to improve electricity delivery and energy reliability.

Our Competitive Strengths

•: Strong and Growing Share in Attractive Markets—We are a leading provider of towers, monopoles and shelters for the U.S. wireless communications infrastructure industry and of electric T&D structures in the United States, based on management's estimates of tower and pole revenues in the industries in which we operate. According to TIA, capital expenditures on wireless infrastructure equipment were $13.7 billion in 2010, and are projected to be $14.5 billion in 2011. Total industry expenditures on transmission investment by EEI members for 2010 were estimated to be $11.1 billion. As a result of our established market leadership, we believe we are well positioned to continue to increase our share of these markets.
•: Leading Engineering and Design Capabilities—We believe we have superior design and engineering capabilities that provide us with a significant competitive advantage. In particular, our internally developed, proprietary end-to-end engineering, design and quoting system for wireless towers employs a multi-pronged approach to develop a tower design that analyzes hundreds of variables (including weight and shape of components, availability of material and inventory,

Table of Contents

production time and scheduling, inventory carrying cost and product standardization) to optimize quality as well as cost.

•: Efficient and Scalable Facilities—We operate a purpose-built, state-of-the-art manufacturing and galvanizing facility strategically located in Alvarado, Texas that is dedicated primarily to the production of electric T&D structures. We believe that this facility gives us a cost advantage over many of our competitors that do not have manufacturing and galvanizing operations located in the same facility. We produce wireless communications towers at our facility in Sioux City, Iowa, which consists of two manufacturing plants. Our Bossier City, Louisiana facility consists of two manufacturing plants dedicated to the production of equipment shelters, which are critical to the protection of our wireless communications infrastructure customers' valuable wireless equipment. Our facilities have the flexibility to expand to meet future demand. These facilities collectively strengthen our position as an efficient, reliable and environmentally responsible provider.
•: Complete Customer Solution—Our reputation as a premier provider of wireless communications and electric T&D infrastructure products has been built on: (i) our dedication to delivering projects on time, on budget and to customer specifications; (ii) our comprehensive suite of products and services, which enables us to serve as a one-stop shop for our wireless communications infrastructure customers; and (iii) our customer-focused perspective at every level of operations and management.
•: Experienced Management Team—Our management team includes seasoned professionals with industry experience that averages over 21 years per person. Under the leadership of our management team, we have grown from a small, single-site domestic manufacturer of wireless communications towers to a diversified provider of infrastructure products to the wireless communications and electric T&D infrastructure markets.

Our Growth Strategy

•: Capitalize On Strong Industry Fundamentals—Our products and services support the operation and expansion of wireless communications and electric T&D infrastructure. We believe that we are well positioned to capitalize on projected infrastructure expenditures in our markets. We intend to leverage our established market leadership to serve the growing needs of the wireless communications infrastructure industry. With the electric T&D infrastructure industry poised for significant investment over the coming years due to the upgrade and expansion of the aging and unreliable U.S. electric power grid, we plan to build on our installed base of electric utility customers to strengthen our pipeline of electric T&D infrastructure projects.
•: Expand and Diversify Our Markets and Our Product and Service Offerings—In order to support the additional weight load and counteract the increased wind resistance resulting from new equipment on wireless structures, we expect both existing and new customers to increase the number of structural modifications to existing wireless structures. In addition, as wireless carriers continue to outsource non-core operating functions, we expect to expand our technical integration and installation services, as well as third-party logistics services, to both existing and new customers. We also believe we have significant opportunities to expand our customer base in new markets, including defense and homeland security, construction services, oil and gas exploration and production and remote data centers. We plan to broaden our presence internationally, particularly in geographic regions that are still building infrastructure for wireless communications networks and lack local infrastructure suppliers that are able to serve their needs. We seek to capitalize on our industry-leading reputation for protecting valuable wireless equipment by expanding from shelters into cabinets and other enclosure products, thereby enabling us to penetrate new market opportunities with existing and new customers.

Table of Contents

•: Invest in Additional Production Capacity—In July 2010, we began construction of an additional plant to add capacity at our Alvarado, Texas facility, which construction remains ongoing. We are also considering additional production facilities in order to serve the demands of our rapidly growing markets, to compete for the largest infrastructure projects and to create manufacturing redundancies that meet customer demand for seamless service. We have a proven ability to design, construct and integrate new production facilities into our existing operations as demonstrated by the successful construction and integration of our purpose-built, state-of-the-art manufacturing and galvanizing facility in Alvarado, Texas. Our expected investments in manufacturing facilities, which may include the construction of new facilities, will enhance our ability to complete the largest infrastructure projects and add manufacturing redundancies to our operations to help ensure uninterrupted customer service.
•: Selectively Pursue Strategic Acquisitions—We intend to pursue a disciplined acquisition strategy to broaden and enhance our product and service offerings, add new customers, expand our sales channels, supplement our internal development efforts and accelerate our growth. We believe that the markets in which we compete are highly fragmented with a large number of potential acquisition opportunities.

Risks Associated with Our Business

There are a number of risks and uncertainties that may affect our business, financial and operating performance, and growth prospects, including:

•: volatility in commodity prices (particularly steel) and our quarterly revenue and operating results;
•: our customers generally have no ongoing obligation to purchase products from us and many of our contracts may be terminated on short notice;
•: our dependence on the overall level of infrastructure spending;

Represents impairment charges recorded in the fourth quarter of fiscal 2010 relating to the fair value of the goodwill of our CellXion reporting unit and one of our trade names. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Summary of Critical Accounting Policies and Estimates—Goodwill and Other Long-Lived Assets" included elsewhere in this prospectus for further detail.

Adjusted EBITDA is defined as net income (loss) plus interest expense net of interest income, plus income tax expense (benefit) and plus depreciation and amortization, or EBITDA, as adjusted for gain or loss on sale of property and equipment, goodwill and intangible asset impairment charges and share-based compensation expense. Adjusted EBITDA is not required by or presented in accordance with generally accepted accounting principles in the United States of America, or GAAP, and should not be considered as an alternative to net income, operating income or any other performance measure derived in accordance with GAAP, or as an alternative to cash flow from operating activities or as a measure of our liquidity.

We present adjusted EBITDA because we consider it to be an important supplemental measure of our operating performance. Adjusted EBITDA is a key measure of our operating performance under our credit agreement and is regularly presented to and considered by our management and board of directors as an important operating metric in their assessment of performance and in forecasting and budgeting, both for individual operating units and for our company as a whole. Historical and projected adjusted EBITDA are also key operating measurements used by management in assessing potential acquisitions. We also make certain compensation decisions based, in part, on our operating performance, as measured by adjusted EBITDA. See "Executive Compensation—Compensation Discussion and Analysis."

We believe adjusted EBITDA allows us to better compare our current operating results with corresponding historical periods and with the operational performance of other companies in our industry because it does not give effect to potential differences caused by variations in capital structures (affecting relative interest expense, including the impact of write-offs of deferred financing costs when companies refinance their indebtedness), tax positions (such as the impact on periods or companies of changes in effective tax rates or net operating losses), the amortization of intangibles (affecting relative amortization expense), share-based compensation expense and other items that are unrelated to underlying operating performance. We also present adjusted EBITDA because we believe it is frequently used by securities analysts and investors as a measure of performance and because it is used by our lenders to monitor covenant compliance.

There are a number of material limitations to the use of adjusted EBITDA as an analytical tool, including the following:

•: Adjusted EBITDA does not reflect our interest expense or the cash requirements to pay our interest. Because we have borrowed money to finance our operations, interest expense is a necessary element of our costs and our ability to generate profits and cash

Table of Contents

flows. Therefore, any measure that excludes interest expense may have material limitations.

•

Adjusted EBITDA does not reflect our tax expense or the cash requirements to pay our taxes. Because the payment of income taxes is a necessary element of our costs, any measure that excludes tax expense may have material limitations.

•

Although depreciation and amortization are non-cash expenses in the period recorded, the assets being depreciated and amortized may have to be replaced in the future, and adjusted EBITDA does not reflect the cash requirements for such replacement. Because we use capital assets, depreciation and amortization expense is a necessary element of our costs and ability to generate profits. Therefore, any measure that excludes depreciation and amortization expense may have material limitations.

•

Because we periodically have granted, and expect to continue to grant, options and restricted share awards to our employees, share-based compensation is a necessary element of our costs and ability to generate profits and cash flows. Therefore, any measure that excludes share-based compensation expense may have material limitations.

We compensate for these limitations by relying primarily on our GAAP financial measures and by using adjusted EBITDA only as supplemental information. We believe that consideration of adjusted EBITDA, together with a careful review of our GAAP financial measures, is the most informed method of analyzing our operations.

Because adjusted EBITDA is not a measurement determined in accordance with GAAP and is susceptible to varying calculations, adjusted EBITDA, as presented, may not be comparable to other similarly titled measures of other companies.

The following table provides a reconciliation of adjusted EBITDA to net income (loss):

RISK FACTORS

You should carefully consider the risk factors described below and all other information contained in this prospectus before you decide to invest in our common stock. Our business, financial condition, results of operations and cash flows could be materially adversely affected by any of these risks, as well as other risks and uncertainties not currently known to us. In that case, the trading price of our common stock could decline, and you may lose part or all of your investment.

Risks Relating to Our Business and Industry

The award of new and, in particular, larger-scale contracts and the timing of these contract awards may result in unpredictable fluctuations in our revenue, cash flow and profitability.

We derive a substantial portion of our revenue from project-based work. It is generally very difficult to predict with precision whether and when we will be awarded a project, when we will start work on a project once it is awarded and the expected project timetable or completion date. As a result, our quarterly revenue and operating results can fluctuate and be difficult to predict. In addition, some of our contracts are subject to regulatory approval, permitting, financing and other contingencies that may delay or result in termination of projects, particularly in an economic environment where financing is difficult to obtain. Because we generally record revenues at the time we ship our products, and not when the order for the products is taken, the timing of completion and delivery of significant customer orders can cause our results to fluctuate from quarter to quarter or from year to year. If expected contract awards are delayed or not received, or if our volume of projects is lower than expected, we could incur substantial costs without receipt of corresponding revenues. Finally, the winding down or completion of work on significant projects that were active in previous periods may lead to reduced revenue and earnings if such significant projects are not replaced in the current period.

Our customers generally have no ongoing obligation to purchase products from us and many of our contracts may be terminated on short notice. As a result, we are at risk of losing significant business on short notice.

Our customers generally have no ongoing obligation to purchase products from us. Our customers could materially reduce, eliminate or reassign a portion of the products we have historically sold to them because our contracts rarely have any minimum volume or purchase obligations or requirements. Moreover, many of our contracts are open to competitive bidding, and we have been displaced on these contracts by competitors from time to time. Our revenue could materially decline if our customers do not assign work to us or if they cancel a significant number of projects and we cannot replace them with similar projects.

Demand for our products could be adversely affected by downturns in the infrastructure construction markets or in government spending related to infrastructure.

Our business is dependent upon infrastructure spending by wireless service providers, utilities, governmental agencies and other organizations. As a result, demand for our products and services could be impacted adversely by general budgetary constraints on our private or governmental customers, including difficulty of customers in obtaining necessary permits or necessary financing, government spending cuts and the inability of government entities to issue debt to finance any necessary infrastructure projects. The infrastructure construction markets historically have been cyclical and down cycles have typically lasted a number of years. Any significant decline in the infrastructure construction markets or in governmental spending on infrastructure could weaken demand for our products and services. As a result of this underlying cyclicality, we have experienced, and in the future we may experience, significant fluctuations in our revenue and operating income.

Table of Contents

Infrastructure construction activity by our private and government customers can be adversely impacted by, among other things:

•: weakness in the general economy, which reduces funds available for construction;
•: interest rate increases, which increase the cost of construction financing; and
•: adverse weather conditions that slow construction activity, such as excessive rain, snow or hurricanes.

We may not have sufficient manufacturing capacity to take advantage of market opportunities, and the lack of redundancies in our manufacturing facilities makes our operations more susceptible to natural disasters.

Our ability to respond to market demand depends on our manufacturing capacity. While we expect to continue investing in manufacturing facilities, which may include the construction of new facilities, there can be no assurance that we will have sufficient manufacturing capacity to enable us to take advantage of future market opportunities, especially during periods of growing demand for our products.

We currently have three manufacturing facilities with little to no redundancy among them. As a result, should a natural disaster such as a hurricane, tornado, earthquake or flood severely damage one of our three manufacturing facilities, our operations could be significantly impacted. We may not be able to replicate the production capacity of such facility at one of our other manufacturing facilities or elsewhere, or such replication could take significant time and resources to accomplish. The disruption from such an event could significantly impact our operations.

Demand for our products may be adversely affected by changes in technology in the markets in which we operate.

The markets for our products and services are characterized by evolving industry standards and the periodic introduction of new technological developments. These new standards and developments could decrease the demand for our products or make our existing or future products or services obsolete. For example, technological advances that increase the capacity of a network with a fixed number of towers could adversely affect long-term demand for our tower products. Keeping pace with the introduction of new standards and technological developments could require us to incur additional costs or prove difficult or impossible. The failure to keep pace with these changes and to continue to enhance and improve the responsiveness, functionality and features of our products and services could significantly impact our operations.

We derive a significant portion of our revenue from a small group of customers. The loss of, or our failure to sustain our revenues from, one or more of these customers could negatively impact our results of operations, cash flow and business prospects.

Our top ten customers accounted for 54.6% and 44.3% of our revenues for the year ended April 30, 2010 and the nine months ended January 31, 2011, respectively. Verizon accounted for 15.2% and 10.2% of our net sales for the year ended April 30, 2010 and the nine months ended January 31, 2011, respectively. In addition, U.S. Cellular accounted for 10.3% and 8.1% of our net sales for the year ended April 30, 2010 and the nine months ended January 31, 2011, respectively. Our revenue could significantly decline if we lose one or more of our significant customers or if they significantly reduce their use of our products or services. In addition, revenue under our contracts with significant customers may vary from period to period depending on the timing and volume of products and services that such customers order in a given period due to their own spending plans and budgetary considerations or as a result of industry consolidation and competition.

Table of Contents

Our success and growth strategy depend on our senior management and our ability to attract and retain qualified personnel.

Our management team includes seasoned professionals with industry experience that averages over 21 years per person. Our Executive Chairman of the Board of Directors, James D. Mack, has served with us for 19 years, and our President and Chief Executive Officer, Peter J. Sandore, has approximately 30 years of industry experience. We depend on our senior management for the success and future growth of our operations and revenue. The loss of any member of our senior management team, particularly Mr. Mack or Mr. Sandore, could have an adverse impact on our operations. Any management transition may be a distraction to senior management as we search for a qualified replacement, could result in significant recruiting, relocation, training and other costs and could cause operational inefficiencies as a replacement becomes familiar with our business and operations.

We face strong competition in our markets.

We face competitive pressures from a variety of companies in each of the markets we serve. The wireless communications infrastructure products and services industry is characterized by a diverse mix of small, regional players in addition to large, diversified national platforms. Years of industry consolidation within the tower and shelter sector has left fewer, but stronger, players. Within our targeted industry segments, we compete with a large number of product manufacturers and service providers, including Fibrebond Corporation, FWT, Inc., Oldcastle Precast, Inc. and Valmont Industries, Inc. In the highly fragmented electric T&D infrastructure industry, our primary competitors include FWT, Inc., Thomas & Betts Corporation and Valmont Industries, Inc. Some of these competitors may have greater financial, manufacturing, marketing and technical resources than we do, or greater penetration in or familiarity with a particular geographic market than we have. To remain competitive, we will need to invest continuously in manufacturing, product development and customer service, and we may need to reduce our prices, particularly with respect to customers in industries that are experiencing downturns. We cannot provide assurance that we will be able to maintain our competitive position in or that we will be able to further penetrate each of the markets that we serve.

If we are unsuccessful in further penetrating our existing markets or entering new markets, our revenue growth could be adversely affected.

The demand for, and market acceptance of, our wireless communications and electric T&D infrastructure products and services is subject to a high level of uncertainty. Intensive marketing and sales efforts may be necessary to educate prospective customers in both new and existing markets regarding our products and services in order to generate additional demand. The market for our products and services may weaken, competitors may develop superior wireless communications and/or electric T&D infrastructure products and services or we may fail to develop acceptable solutions to address new market conditions, including technological developments. As a result, we may be unable to further penetrate existing markets or enter new markets for our products and services.

The effect of federal and state legislative and regulatory developments on wireless communications infrastructure and electric T&D infrastructure spending is uncertain and such developments may fail to result in increased demand for our products.

In recent years, federal and state legislation has been passed and resulting regulations have been adopted that could significantly increase spending on electric power transmission, including the Energy Policy Act of 2005, which we refer to as the Energy Act, the American Recovery and Reinvestment Act of 2009, which we refer to as ARRA, and state mandatory RPS programs. ARRA and subsequent stimulus spending initiatives also could increase spending on wireless communications infrastructure through wireless vendors. However, there remains considerable fiscal, regulatory and other uncertainty as to the impact that this legislation and other regulations will ultimately have on the demand for our products and services.

Table of Contents

The Federal Communications Commission, or the FCC, has promulgated new rules regarding Enhanced 911, which we refer to as E-911, which requires routing of 911 calls to geographically appropriate public safety answering points based on the caller's location. The FCC's final determination on the location accuracy standards of E-911 is expected to be released in the near future and advances in the E-911 system may also be addressed through subsequent notices or additional standards. Changes in such standards may adversely affect demand for our wireless communications products and services. Further, other general legislation and regulation relating to wireless communications networks, technologies, distribution, standards, cell site deployment or development, such as The National Broadband Plan or Rural Utilities Service Broadband Initiatives Program, may similarly impact the demand for our wireless communications products and services.

Regulations implementing provisions of the Energy Act that may affect demand for our products remain, in some cases, subject to review in various federal courts. The Energy Act may not streamline the process for permitting new transmission projects or eliminate the barriers to new transmission investments. As a result, the Energy Act may not result in the anticipated increase in spending on the electric T&D infrastructure. Continued uncertainty regarding new infrastructure investments and the implementation and impact of the Energy Act may result in slower growth in demand for our products and services.

While 29 states, the District of Columbia and Puerto Rico have mandatory RPS programs that require certain percentages of power to be generated from renewable sources, the RPS programs adopted in many states became law during periods of substantially higher oil and natural gas prices. As a result, for budgetary or other reasons, states may reduce those mandates or make them optional or extend deadlines, which could reduce, delay or eliminate renewable energy development in the affected states. In addition, states may limit, delay or otherwise alter existing RPS programs in anticipation of a potential federal renewable energy standard. Funding for RPS programs may not be available or may be further constrained as a result of the significant declines both in government budgets and subsidies and in the availability of credit to finance the significant capital expenditures necessary to build renewable generation capacity. These factors could lead to fewer projects resulting from RPS programs than anticipated or a delay in the timing of these projects and the related infrastructure, which would negatively affect the demand for our products and services. In addition, we cannot predict when programs under ARRA will be implemented or the timing and scope of any investments to be made under these programs.

We have substantial debt obligations, which could impair our ability to operate our business and react to changes in our business and markets.

While we intend to use the proceeds of the offering to repay a portion of our outstanding indebtedness, we will continue to have significant debt obligations. As of January 31, 2011, on an actual basis and on an as adjusted basis after giving effect to the sale of shares of our common stock in the offering at an assumed initial public offering price of $ per share (the midpoint of the price range set forth on the cover page of this prospectus) and the application of the estimated net proceeds from the offering as described under "Use of Proceeds," we had $121.3 million and $ , respectively, in total debt obligations. Our substantial debt obligations may:

•: require us to dedicate a substantial portion of our cash flow to payments on our debt obligations, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, acquisitions and other corporate requirements;
•: subject us to increases in interest rates on our variable-rate debt, including the borrowings under our existing credit agreement; and
•: make us more vulnerable to a downturn in our business and competitive pressures, and limit our flexibility to plan for, or react to, changes in our business.

Table of Contents

Our credit agreement also includes various financial and operating covenants that limit our ability to engage in acquisitions and certain other transactions and requires us to apply proceeds from equity offerings and certain other transactions to reduce indebtedness. A breach of any of the covenants contained in our credit agreement could result in an event of default and allow the lenders to pursue various remedies, including accelerating the repayment of any indebtedness outstanding under the credit agreement.

We may not realize the improved operating results that we anticipate from acquisitions we may make in the future, and we may experience difficulties in integrating acquired businesses or may inherit significant liabilities related to such businesses.

As part of our business strategy, we may, from time to time, acquire additional companies and businesses. We may experience difficulties and incur significant costs as a result of evaluating, completing and integrating acquisitions. In addition, we may finance future acquisitions through additional issuances of stock that could be dilutive to our stockholders or by incurring additional debt that would increase our leverage. Any acquisition involves significant risks and uncertainties, including the following:

•: we may not realize expected synergies from the transaction;
•: it may be difficult for us to successfully integrate the acquired operations into our company and maintain uniform standards, controls, policies and procedures;
•: our management's time and attention may be diverted from existing business operations by transition or integration issues;
•: we may not be able to retain the key employees of the acquired operation;
•: it may be difficult for us to conform the financial reporting procedures of an acquired business to those required of a U.S. reporting company, including procedures required by the Sarbanes-Oxley Act of 2002; and
•: unidentified issues could arise that we did not discover in our due diligence process, including liabilities, commitments and/or contingencies of the acquired company.

We could incur substantial costs as the result of violations of, or liabilities under, environmental laws.

Our facilities and operations are subject to U.S. laws and regulations relating to the protection of the environment, including those governing the discharge of pollutants into the environment, the management and disposal of hazardous substances and wastes, and the cleanup of contamination. Failure to comply with these laws and regulations, or with the permits required for our operations, could result in fines or civil or criminal sanctions, third-party claims for property damage or personal injury, and corrective investigation and cleanup costs. Some laws impose strict liability and in certain circumstances joint and several liability on current and former owners and operators of contaminated sites and other potentially responsible parties for investigation, cleanup and other costs. Potentially significant expenditures could be required in order to comply with environmental laws that may be adopted or imposed in the future, including those imposed in response to climate change concerns. Compliance with any current or future laws and regulations could have an adverse effect on our business and results of operations.

Wireless communications and electric T&D structures are subject to deterioration or failure over time, and we may not maintain adequate insurance coverage for product liability.

Due to weather conditions, ground conditions or other forces, our towers and other products that we manufacture are subject to deterioration over time and, in extreme cases, may fall over or collapse. One of our towers collapsed during our 2010 fiscal year, which resulted in property damage

Table of Contents

but no personal injury. Such product failures could result in damage to our reputation for high-quality products, which could have an adverse effect on our business and results of operations.

Certain risks are inherent in our products and our insurance may not be adequate to cover potential claims against us involving our products. Although we currently maintain liability insurance, we cannot assure that the coverage limits under these insurance programs will be adequate to protect us against future claims, or that we can and will maintain this insurance on acceptable terms in the future.

We may incur liabilities or suffer adverse financial consequences as a result of occupational health and safety matters.

Our operations are subject to extensive laws and regulations relating to the maintenance of safe conditions in the workplace. Our industry involves a high degree of operational risk and there can be no assurance that we will avoid significant liability exposure. Our business is subject to numerous safety risks, such as electrocutions, fires, burns, eye injuries, falls, mechanical failures, weather-related incidents, transportation accidents and damage to equipment on which we work. These hazards can cause personal injury and loss of life, severe damage to or destruction of property and equipment and other consequential damages and could lead to suspension of operations, large damage claims and, in extreme cases, criminal liability.

Seasonal and other variations, including severe weather conditions, may cause significant fluctuations in our financial condition, results of operations and cash flows.

Although our revenue is primarily driven by spending patterns in our customers' industries, our revenue and results of operations can be subject to seasonal variations. These variations are influenced by weather, hours of daylight, customer spending patterns, bidding seasons and holidays, and can have a significant impact on our gross margins. Our profitability may decrease during the winter months and during severe weather conditions because work performed during these periods may be restricted. Additionally, our revenue will fluctuate based on the timing and volume of large projects, particularly in our electric T&D infrastructure segment. Working capital needs are also influenced by the seasonality of our business. Accordingly, significant disruptions in our ability to recognize revenue due to these seasonal variations and timing or reductions of large projects could have a material adverse effect on our financial condition, results of operations and cash flows.

We may be unable to retain the subcontractors we need to manufacture and install certain products, and the use of subcontractors may cause production and installation delays, result in additional costs, reduce profitability and/or damage customer relationships.

We use subcontractors to manufacture and install portions of some of our products, which can reduce our margins. General market conditions may limit the availability of subcontractors on which we rely to perform portions of our contracts. In addition, we are responsible to our customers for the work performed by our subcontractors. Failure by a subcontractor to satisfactorily manufacture or install products in a timely and cost-effective manner may result in delays in production, cause us to incur additional costs and/or damage customer relationships. While we typically receive indemnities from most of our subcontractors covering certain claims, we may not be able to recover under those indemnities or they may not be adequate.

Increases in prices and reduced availability of key raw materials such as steel and zinc will increase our operating costs and likely reduce our profitability.

Steel constitutes a significant portion of our materials cost. We also use large quantities of zinc for the galvanization of most of our steel products. Although we are able to pass through most increases in the cost of raw materials, particularly steel, to our customers, and have strengthened our

Table of Contents

strategic sourcing of this critical input, the markets for the commodities that we use in our manufacturing processes can be volatile. Increases in the selling prices of our products may not fully recover additional steel and zinc cost and generally lag increases in our costs for these commodities. Consequently, an increase in steel and zinc prices will increase our operating cost and likely reduce our profitability.

Our operating results and the market price of our common stock could be materially adversely affected if we are required to record impairment charges relating to the carrying value of goodwill or intangible assets.

In connection with our annual goodwill impairment analysis in the fourth quarter of fiscal 2010, we determined that the goodwill balance attributable to our CellXion reporting unit was impaired. In addition, our impairment analysis of our intangible assets and other long-lived assets during the fourth quarter of fiscal 2010 indicated that the trade name intangible associated with our CellXion reporting unit was impaired as a result of a decline in projected future operating results. Accordingly, we recorded goodwill and intangible asset impairment charges of $9.7 million and $3.1 million, respectively. As of January 31, 2011, the remaining carrying values of our consolidated goodwill and intangible assets were $19.2 million and $32.0 million, respectively.

The general economic downturn has impacted our financial results and has reduced purchases by certain of our key customers and may continue to do so in the future. We may determine that our expectations of future financial results and cash flows for one or more of our reporting units has decreased or a decrease in our stock valuation may occur, which could result in a review of our goodwill and intangible assets associated with these reporting units and require us to record additional impairment charges relating to the carrying value of goodwill, intangible assets or other long-lived assets. As a result, our operating results and the market price of our common stock may be materially adversely affected.

Risks Relating to Our Relationship with Our Significant Stockholder

Following the offering, Corinthian Capital will continue to own a significant percentage of our common stock and, therefore, will have a significant influence on the outcome of director elections and other matters requiring stockholder approval, including a change in corporate control.

Following the offering, Corinthian Capital will own approximately % of our outstanding common stock, or % of our outstanding common stock if the underwriters exercise their overallotment option in full. As a result of this ownership position, Corinthian Capital will continue to have a significant influence on the outcome of matters requiring stockholder approval, including:

•: election of our directors;
•: amendment of our certificate of incorporation or bylaws; and
•: approval of mergers, consolidations or the sale of all or substantially all of our assets.

Corinthian Capital may vote its shares of our common stock in ways that are adverse to the interests of other holders of our common stock, including investors in the offering. Its significant ownership interest could delay, prevent or cause a change in control of our company, any of which could adversely affect the market price of our common stock. In addition, Corinthian Capital's significant percentage of share ownership may adversely affect the trading price of our common stock because investors may perceive disadvantages in owning stock in companies with a significant stockholder. For additional information regarding our relationship with Corinthian Capital, see "Certain Relationships and Related-Party Transactions."

Table of Contents

Corinthian Capital and its designees on our board of directors may have interests that conflict with our interests and the interests of our other stockholders.

Corinthian Capital and its designees on our board of directors may have interests that conflict with, or are different from, our own and those of our other stockholders. If an actual or potential conflict of interest develops involving one of our directors, our corporate governance guidelines, which will be adopted prior to the completion of the offering, will provide that the director must report the matter immediately to our board of directors and audit committee for evaluation and appropriate resolution. Furthermore, such director will be required to recuse himself from participation in the related discussion and abstain from voting on the matter. Nonetheless, conflicts of interest may not be resolved in a manner favorable to us or our other stockholders.

Risks Relating to the Offering and Ownership of Our Common Stock

Our stock price may be volatile or may decline regardless of our operating performance, and you may not be able to resell your shares at or above the initial public offering price.

Prior to the offering, there has been no public market for our common stock, and an active public market for our common stock may not develop or be sustained after the offering. The initial public offering price for our common stock will be determined through negotiations between the underwriters, the selling stockholders and us. This initial public offering price will not necessarily reflect the price at which investors in the market will be willing to buy and sell our shares following the offering. If you purchase shares of our common stock, you may not be able to resell those shares at or above the initial public offering price. We cannot predict the extent to which investor interest in us will lead to the development of a trading market in our common stock or how liquid that market might become. If an active public market does not develop or is not sustained, it may be difficult for you to sell your shares of common stock at a price that is attractive to you, or at all. The market price of our common stock may fluctuate significantly in response to numerous factors, many of which are beyond our control and some of which may not be related to our actual operating performance.

In addition, in the past, following periods of volatility in the overall market and the market price of a particular company's securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management's attention and resources from our business.

If there are substantial sales of our common stock or issuances of our common stock by us, our stock price could decline.

The market price of our common stock could decline as a result of sales of a large number of shares of our common stock in the market after the offering or the perception that these sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.

Upon completion of the offering, shares of our common stock will be outstanding. All of the shares of common stock expected to be sold in the offering will be freely tradable without restriction or further registration under the Securities Act of 1933, as amended, or the Securities Act, unless held by our "affiliates," as that term is defined in Rule 144 under the Securities Act. The resale of the remaining shares, or % of our outstanding shares after the offering, is currently prohibited or otherwise restricted as a result of securities law provisions, market stand-off agreements entered into by our stockholders with us or lock-up agreements entered into by our stockholders with the underwriters; however, subject to applicable securities law restrictions and certain extensions, these shares will be able to be sold in the public market beginning 180 days after the date of this prospectus. In addition, the shares subject to outstanding options, of which are exercisable as of January 31, 2011, and the shares reserved for future issuance under our stock option and equity incentive plans will become available for sale immediately upon the

Table of Contents

exercise of such options and the expiration of any applicable market stand-off or lock-up agreements. For more information see "Shares Eligible for Future Sale."

In addition, in the future, we may issue additional shares of common stock or other equity or debt securities convertible into common stock in connection with a financing, acquisition, employee arrangement or otherwise. Any such issuance could result in substantial dilution to our existing stockholders and could cause the value of our common stock to decline.

We currently do not intend to pay dividends on our common stock.

We currently do not plan to declare dividends on shares of our common stock. Further, our payment of dividends is restricted by our credit agreement. See "Dividend Policy" for more information. Consequently, your only opportunity to achieve a return on your investment in our company will be if the market price of our common stock appreciates and you sell your shares at a profit.

Provisions of our charter documents and Delaware corporation law might deter acquisition bids for us that you might consider favorable.

Certain provisions of our amended and restated certificate of incorporation and bylaws that will be in effect upon completion of the offering may make it more difficult for a third party to acquire control of us or effect a change in our board of directors and management. These provisions include: a lack of cumulative voting in the election of directors; our board's ability to authorize the issuance of undesignated preferred stock without stockholder approval, which may include rights superior to the rights of the holders of common stock; elimination of stockholder action by written consent; and advance notice requirements for nominations for election to our board or for proposing matters that can be acted upon by stockholders.

In addition, we are subject to Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with a stockholder owning 15% or more of our outstanding voting stock for a period of three years following the date on which the stockholder became an "interested" stockholder. In order for us to consummate a business combination with an "interested" stockholder, either (1) the business combination or the transaction that resulted in the stockholder becoming "interested" must be approved by our board of directors prior to the date the stockholder became "interested" or (2) the business combination must be approved by our board of directors and authorized by at least two-thirds of our stockholders (excluding the "interested" stockholder). This provision could have the effect of delaying or preventing a change of control, whether or not it is desired by or beneficial to our stockholders.

If securities or industry analysts do not publish research or reports about our business, or if they publish unfavorable research about our business or our stock, our stock price and trading volume could decline.

The trading market for our common stock will be influenced in part by the research and reports that securities or industry analysts publish about us or our business. We do not currently have and may never obtain research coverage by securities analysts. If no securities or industry analysts commence coverage of us, the trading price for our stock may be negatively affected. If securities or industry analysts do begin coverage of us, and if one or more of the analysts who cover us downgrades our stock or publishes unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, we could lose visibility in the financial markets, which could cause our stock price and trading volume to decline.

Table of Contents

We will be subject to additional regulatory compliance requirements, including Section 404 of the Sarbanes-Oxley Act of 2002, as a result of becoming a public company and our management has limited experience managing a public company. Failure to comply with these requirements could harm our business.

We have never operated as a public company and will incur significant legal, accounting and other expenses that we did not incur as a private company. Our management team and other personnel will need to devote a substantial amount of time to new compliance initiatives and to meeting the obligations that are associated with being a public company, and we may not successfully or efficiently manage our transition into a public company. We expect rules and regulations such as the Sarbanes-Oxley Act of 2002 to increase our legal and finance compliance costs and to make some activities more time-consuming. Furthermore, Section 404 of the Sarbanes-Oxley Act of 2002 requires that our management report on, and our independent registered public accounting firm attest to, the effectiveness of our internal controls over financial reporting beginning with our annual report on Form 10-K for the year ending April 30, 2012. Section 404 compliance may divert internal resources and will take a significant amount of time and effort to complete. We may not be able to successfully complete the procedures and certification and attestation requirements of Section 404 by the time we will be required to do so. If we fail to do so, or if in the future our Chief Executive Officer, Chief Financial Officer or independent registered public accounting firm determines that our internal control over financial reporting is not effective as defined under Section 404, we could be subject to sanctions or investigations by the exchange on which we will list our shares, the Securities and Exchange Commission, or SEC, or other regulatory authorities. Furthermore, investor perceptions of our company may suffer, and this could cause a decline in the market price of our stock. Irrespective of compliance with Section 404, any failure of our internal controls could have a material adverse effect on our results of operations and harm our reputation. If we are unable to implement these changes effectively or efficiently, it could harm our operations, financial reporting or financial results and could result in an adverse opinion on internal controls from our independent registered public accounting firm.

USE OF PROCEEDS

We estimate that we will receive net proceeds from the sale of our common stock in the offering of approximately $ million, based upon an assumed initial public offering price of $ per share (the midpoint of the price range set forth on the cover of this prospectus) and after deducting underwriting discounts and commissions and estimated offering expenses payable by us. A $1.00 increase or decrease in the assumed initial public offering price of $ per share would increase or decrease the net proceeds to us from the offering by approximately $ million, assuming the number of shares offered by us, as indicated on the cover page of this prospectus, remains the same and after deducting the underwriting discounts and commissions and estimated offering expenses payable by us.

We intend to use the net proceeds to us from the offering to repay indebtedness outstanding under our credit agreement, the weighted average interest rate of which was 3.52% as of January 31, 2011 and which matures on December 31, 2011.

We will not receive any of the proceeds from the sale of shares of our common stock by the selling stockholders.

DIVIDEND POLICY

We currently do not anticipate paying any cash dividends after the offering. Instead, we anticipate that all of our earnings on our common stock will be used to provide working capital to support our operations and to finance the growth and development of our business. Any future determination relating to dividend policy will be made at the discretion of our board of directors and will depend on a number of factors, including our future earnings, capital requirements, financial condition, future prospects and other factors as our board of directors may deem relevant. The ability of our board of directors to declare any cash dividends is subject to limits imposed by the terms of our credit agreement, which currently prohibits us from paying dividends on our common stock.

DILUTION

If you invest in our common stock in the offering, you will experience immediate and substantial dilution in the pro forma net tangible book value of your shares of our common stock. The pro forma net tangible book value of our common stock as of January 31, 2011 was $ million, or approximately $ per share. Pro forma net tangible book value per share represents the amount of our total tangible assets less our total liabilities divided by the pro forma number of shares of common stock outstanding on January 31, 2011.

Dilution in pro forma net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock in the offering and the pro forma net tangible book value per share of our common stock immediately after the completion of the offering. After giving effect to the sale of shares of our common stock in the offering at an assumed public offering price of $ (the midpoint of the estimated price range shown on the cover page of this prospectus) and after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma net tangible book value as of January 31, 2011 would have been approximately $ million, or approximately $ per share. This represents an immediate increase in pro forma net tangible book value of $ per share to existing stockholders and an immediate dilution of $ per share to new investors purchasing shares of our common stock in the offering at the assumed initial public offering price. The following table illustrates this per share dilution:


Assumed initial public offering price per share		$

Pro forma net tangible book value as of January 31, 2011	$

Increase per share attributable to new investors in the offering

Pro forma as adjusted net tangible book value per share after the offering

Dilution per share to new investors		$

If the underwriters exercise their overallotment in full, pro forma net tangible book value per share after the offering will be $ , and dilution in pro forma net tangible book value per share to new stockholders will be $ . A $1.00 increase (decrease) in the assumed initial public offering price of $ per share would increase (decrease) our pro forma net tangible book value by $ million, the pro forma net tangible book value per share after the offering by $ per share and the dilution in pro forma net tangible book value to new investors in the offering by $ per share, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same.

The following table presents, on a pro forma basis, as of January 31, 2011, the differences between the number of shares of common stock purchased from us, the total consideration paid or exchanged and the average price per share paid by existing stockholders and by new investors purchasing shares of our common stock in the offering before deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us. The table assumes an initial public offering price of $ per share, as specified above.

Table of Contents

A $1.00 increase (decrease) in the assumed initial public offering price of $ per share would increase (decrease) total consideration paid by new stockholders by $ million, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same.

The number of shares outstanding in the table above is based on the number of shares outstanding as of January 31, 2011. The discussion and tables above do not include the following shares:

•: shares of our common stock issuable upon the exercise of stock options outstanding as of January 31, 2011 with a weighted average exercise price of $ per share; and
•: shares of our common stock reserved for future issuance under our equity incentive plan.

To the extent any such shares of common stock are issued, new investors may experience further dilution. If the underwriters exercise their overallotment option in full, the following will occur: (1) the number of shares held by existing stockholders will represent approximately % of the total number of shares outstanding after the offering; and (2) the number of shares held by new investors will be increased to , or approximately % of the total number of shares of common stock outstanding after the offering.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our consolidated financial statements and related notes included elsewhere in this prospectus. Our consolidated financial statements have been prepared in accordance with GAAP. Statements in this prospectus that are not historical facts are forward-looking statements within the meaning of the federal securities laws. These statements may contain words such as "expects," "anticipates," "intends," "plans," "believes," "seeks," "estimates" or other wording indicating future results or expectations. Forward-looking statements are subject to significant risks and uncertainties. Our actual results may differ materially from the results discussed in these forward-looking statements. Factors that could cause our actual results to differ materially include, but are not limited to, those discussed under "Risk Factors" and "Special Note Regarding Forward-Looking Statements" and elsewhere in this prospectus. Our business, prospects, financial condition, results of operations or cash flows could be materially adversely affected by any of these factors.

Overview

We are a leading provider of a broad array of highly engineered products for the wireless communications and electric T&D infrastructure markets, based on management's estimates of tower and pole revenues in the industries in which we operate. These products, including towers, monopoles, transmission structures, wood pole equivalents, shelters and ancillary components, are critical to the development, expansion and maintenance of both wireless communications networks and electric T&D systems. In the last 19 years, we have grown from a regional provider of towers for the wireless communications market into a national provider of a diversified suite of products for both the wireless communications and electric T&D infrastructure markets.

Our electric T&D infrastructure reportable segment supplies a broad line of electric transmission and distribution poles and structures, including transmission structures, wood pole equivalents and substation structures. Since the construction of our purpose-built, state-of-the-art manufacturing and galvanizing facility in Alvarado, Texas in 2007 and 2008, we have become a leading provider of electric T&D structures in the United States, based on management's estimates of pole revenues in the industry. We serve key electric utilities and regional transmission organizations such as Duke Energy Corporation, Georgia Transmission Corporation, PacifiCorp and Salt River Project. We believe that our Alvarado, Texas facility gives us a cost advantage over many of our competitors that do not have manufacturing and galvanizing operations located in the same facility.

Factors and Trends Affecting Our Results of Operations

Capital Expenditure Budgets of our Customers

The capital expenditure budgets of large wireless communications and electric T&D companies are a key factor in determining our net sales and profitability. These companies reduced their capital expenditures during the recent economic downturn, which correspondingly had an adverse impact on

Table of Contents

our net sales and profitability in fiscal year 2010 and in the first half of fiscal year 2011. However, we believe that, as evidenced by the results for the three months ended January 31, 2011, economic conditions are beginning to improve and activity and spending in the industries we serve will continue to increase in the remainder of fiscal year 2011 and into fiscal year 2012. Increased wireless data usage, wireless device penetration and rising demand for higher quality of service have spurred the development of 3G and 4G wireless networks, which are expected to increase network infrastructure requirements. We believe that electric T&D companies may increase expenditures in the future because reduced expenditures over the past several years have resulted in a backlog of pending infrastructure projects, including, for example, the NEEWS (New England East-West Solutions) Project, for which we were awarded a purchase order in May 2010 from National Grid for approximately 750 345kV structures for the Rhode Island portion of the project, as well as the Susquehanna-Roseland Transmission Line Project, for which we received a purchase order in July 2010 from Public Service Electric and Gas Company for 63 500kV structures.

Segment Results

In the year ended April 30, 2010, approximately 68% and 32% of our net sales were derived from our wireless communications infrastructure and electric T&D infrastructure segments, respectively, compared to 88% and 12%, respectively, in 2005. In the nine months ended January 31, 2011, approximately 73% and 27% of our net sales were derived from our wireless communications infrastructure and electric T&D infrastructure segments, respectively. We believe that electric T&D infrastructure revenue will account for a greater portion of our net sales in the future. Historically, gross margins in our electric T&D infrastructure segment have exceeded those of our wireless communications infrastructure segment.

Cost of Raw Materials

Raw materials, primarily steel, comprise the primary component of our cost of goods sold. Steel prices significantly affect our net sales and profitability. Steel constitutes a significant portion of our materials cost. Rising steel prices tend to increase our net sales, while falling steel prices tend to reduce our net sales. We generally pass along changes in the price of steel and other raw materials to our customers. Our pricing to our customers includes the underlying cost of steel plus a markup for engineering, fabrication, overhead and profit. Although our gross margin markup has been relatively stable, our gross profit will vary as a function of the underlying cost of steel. As global demand for steel dropped in the year ended April 30, 2010, the price of steel and our net sales decreased accordingly. During the year ended April 30, 2010, the average price of steel according to American Metal Markets was $0.32 per pound, a decline of $0.15 per pound, or 32.5%, from the average price of $0.47 per pound for the year ended April 30, 2009. Our net sales declined from $302.1 million for the year ended April 30, 2009 to $255.3 million for the year ended April 30, 2010. The general relationship between steel prices and our net sales also prevailed in the nine months ended January 31, 2011. During the nine months ended January 31, 2011, the average price of steel according to American Metal Markets was $0.37 per pound, an increase of $0.07 per pound, or 23.3%, from the average price of $0.30 per pound for the nine months ended January 31, 2010. Our net sales increased from $192.5 million for the nine months ended January 31, 2010 to $201.5 million for the nine months ended January 31, 2011.

Project-Based Sales

In any period, our electric T&D infrastructure net sales and profitability often depend upon the completion of large projects. Due to the timing of these large projects, our net sales and profitability can fluctuate and be difficult to predict from period to period. Whether a project is shipped on the last day of one period or the first day of the following period can affect the trend

Table of Contents

reflected in our period-to-period results. A substantial portion of our net sales is derived from project-based work that is awarded through a competitive bid process. It is generally difficult to predict the timing and geographic distribution of the projects that we will be awarded. The selection of, timing of or failure to obtain projects, delays in awards of projects, the re-bidding or termination of projects due to budget overruns, cancellations of projects or delays in completion of contracts could result in the under-utilization of our manufacturing capacity and reduce our cash flows.

Customer Concentration

Our customers generally are large companies and a relatively small number of companies account for a large portion of our net sales. Our top ten customers accounted for 54.6% and 44.3% of our revenues for the year ended April 30, 2010 and the nine months ended January 31, 2011, respectively. Our net sales could significantly decline if we lose one or more of our significant customers or if they significantly reduce their use of our products or services. In addition, net sales under our contracts with significant customers may vary from period to period depending on the timing and volume of products and services that such customers order in a given period due to their own spending plans and budgetary considerations or as a result of industry consolidation and competition.

International Sales

Our international sales decreased from $13.6 million for the year ended April 30, 2009 to $4.5 million for the year ended April 30, 2010, due to the global economic downturn and tightening of the credit markets. Our international sales increased from $3.8 million for the nine months ended January 31, 2010 to $4.1 million for the nine months ended January 31, 2011, due to continued sales efforts in Latin America and new projects in Canada. We plan to broaden our presence internationally, particularly in geographic regions that are still building infrastructure for wireless communications networks and lack local infrastructure suppliers that are able to serve their needs, such as the Middle East, Africa and Latin America.

Manufacturing Capacity

Our ability to generate net sales depends on our manufacturing capacity. The opening of our Alvarado facility in fiscal 2008 enabled us to handle larger projects and has been a major factor in our growth since then. While we expect to continue investing in manufacturing facilities, which may include the construction of new facilities, there can be no assurance that we will have sufficient manufacturing capacity to enable us to take advantage of future market opportunities, especially during periods of growing demand for our products.

CellXion Acquisition

On September 12, 2007, we acquired CellXion, LLC in a transaction accounted for using the purchase method of accounting. The acquisition of CellXion, LLC has enabled us to expand our wireless communications infrastructure segment to include the shelters critical to the protection of valuable wireless communications equipment. The total purchase price of $87.5 million, prior to the final contingent purchase price adjustment, included CellXion membership interests valued at $81.0 million and acquisition-related expenses of $6.5 million. During the fourth quarter of fiscal 2010, we reached an agreement with the prior owners of CellXion on the amount of the contingent portion of the purchase price, which was $1.9 million. This additional purchase price was recorded during the fourth quarter of fiscal 2010 as an increase to goodwill. We may make acquisitions in the future to expand our product lines.

General and Administrative Expenses

We expect an increase in our general and administrative expenses related to the costs of operating as a public company, which will be offset in part by savings resulting from termination of our management fee to Corinthian Capital, which was $0.8 million, $0.8 million and $0.6 million for the years ended April 30, 2009 and 2010, and the nine months ended January 31, 2011, respectively.

Seasonality and Cyclicality

Although our net sales are primarily driven by spending patterns in our customers' industries, our net sales and results of operations can be subject to seasonal variations. These variations are influenced by weather, hours of daylight, customer spending patterns, bidding seasons and holidays, and can have a significant impact on our gross margins. Our profitability may decrease during the winter months and during severe weather conditions because work performed during these periods may be restricted. Additionally, our net sales will fluctuate based on the timing and volume of large projects, particularly in our electric T&D infrastructure segment. Working capital needs are also influenced by the seasonality of our business. Accordingly, significant disruptions in our ability to recognize revenue due to these seasonal variations and timing or reductions of large projects could have a material adverse effect on our financial condition, results of operations and cash flows.

Three Months Ended January 31, 2011 Compared to Three Months Ended January 31, 2010

Net sales

Total net sales increased by $13.8 million, or 22.6%, from $60.8 million during the three months ended January 31, 2010 to $74.6 million during the three months ended January 31, 2011. This increase was mainly the result of an improvement in sales of wireless communications structures of $7.6 million, as well as increases in electric T&D infrastructure net sales of $6.2 million. The wireless communications infrastructure net sales increase over the corresponding prior-year period reflects the positive impact of 9.1% higher volumes generating $7.1 million of net sales, as well as a $0.5 million improvement in pricing due to increases in demand. A large portion of the volume increase was the result of improved unit sales volume of wireless communications towers and monopoles, including wireless communications component parts. This volume increase was primarily due to increased market share with significant customers, increased demand internationally from customers in Latin America

Table of Contents

and Canada, and strong U.S. government demand for our wireless communications infrastructure products. In addition to the increase in wireless communications infrastructure net sales, net sales increased by $6.2 million in the electric T&D infrastructure segment. The electric T&D infrastructure segment experienced a significant unit volume increase of 55.5% from the three months ended January 31, 2010 as a result of several large infrastructure project awards. The higher unit volumes generated an additional $9.2 million of net sales. These increases were partially offset by significant competitive pricing pressure in the electric T&D infrastructure segment, which resulted in a $3.0 million decrease in sales. The significant pricing pressure is the result of project delays caused by the economic downturn, which have led to fewer projects overall and increased competition for each project.

Gross profit

Gross profit increased by $2.0 million, or 16.6%, from $12.1 million for the three months ended January 31, 2010 to $14.2 million for the three months ended January 31, 2011. $3.1 million of this increase was directly related to higher wireless communications and electric T&D infrastructure sales volumes. This increase was partially offset by $1.1 million in higher production costs, which were partially the result of increased steel prices that we were not able to fully pass on to our customers because of the competitive pricing environment as well as an unfavorable sales mix. Gross profit as a percentage of sales decreased from 20.0% for the three months ended January 31, 2010 to 19.0% for the three months ended January 31, 2011. The decreased gross margin for the three months ended January 31, 2011 was mainly due to increased competitive pricing pressures in our electric T&D infrastructure segment and an unfavorable sales mix.

General and administrative expenses

General and administrative expenses decreased by $1.0 million, or 9.7%, from $10.8 million for the three months ended January 31, 2010 to $9.8 million for the three months ended January 31, 2011. This decrease was related to a $0.3 million reduction of amortization expense associated with intangible assets, which were fully amortized in fiscal year 2010, as well as a $0.3 million reduction in legal expense associated with acquisition arbitration costs. Additionally, there were other expense reductions in the three months ended January 31, 2011 associated with management initiatives to increase profitability.

Gain (loss) on sale of property and equipment

There were no significant gains or losses from the sale of property and equipment in the three months ended January 31, 2010 compared to a loss of $0.2 million in the three months ended January 31, 2011. The loss in the three months ended January 31, 2011 related to the disposal of acid regeneration equipment at our galvanizing facility in Alvarado, Texas. Our leased facilities represented approximately 88% of our available production square footage in each of the three months ended January 31, 2010 and 2011. In our wireless communications infrastructure reportable segment, our leased production facilities represented approximately 71% of our production capacity in each of the three months ended January 31, 2010 and 2011. Our Bossier City, Louisiana facility, which we lease as a result of the sale-leaseback transaction consummated during fiscal year 2009, constituted approximately 59% of our production capacity for our wireless communications infrastructure reportable segment in each of the three months ended January 31, 2010 and 2011. In our electric T&D infrastructure reportable segment, our only leased facility is our Alvarado, Texas pole plant facility, which we lease as a result of the sale-leaseback transaction consummated during fiscal year 2009, and which represented approximately 91% of our production capacity in the three months ended January 31, 2010 and 2011. The facility utilization rates for our wireless communications infrastructure reportable segment were approximately 82% and 89% for the three months ended January 31, 2010

Table of Contents

and 2011, respectively. Utilization rates for our wireless communications infrastructure reportable segment are based on the number of units produced as a percentage of the total normal capacity of that reportable segment's production facilities. The facility utilization rates for our electric T&D infrastructure reportable segment were approximately 75% and 110% for the three months ended January 31, 2010 and 2011, respectively. Utilization rates for our electric T&D infrastructure reportable segment are based on the pounds of steel produced as a percentage of the total normal capacity of that reportable segment's production facilities. Capacity can be expanded above normal capacity by adding additional shifts and increasing overtime.

Income tax expense (benefit)

We recorded income tax expense of $0.7 million for the three months ended January 31, 2011, with an effective tax rate of 27.1%, compared to an income tax benefit of $0.4 million for the three months ended January 31, 2010, with an effective tax rate of 34.9%. The increase in the income tax expense is primarily attributable to an increase in taxable income of $3.7 million.

Nine Months Ended January 31, 2011 Compared to Nine Months Ended January 31, 2010

Net sales

Total net sales increased by $8.9 million, or 4.6%, from $192.5 million during the nine months ended January 31, 2010 to $201.5 million during the nine months ended January 31, 2011. This increase was mainly the result of an improvement in sales of wireless communications infrastructure products of $11.5 million partially offset by a decrease in electric T&D infrastructure net sales of $2.6 million. The wireless communications infrastructure net sales increase over the corresponding prior-year period reflects the positive impact of 10.6% higher volumes generating $18.4 million in net sales, which were partially offset by competitive pricing pressures, reducing net sales by $6.8 million. A large portion of the volume increase was the result of improved unit sales of wireless communications towers and monopoles, including wireless communications component parts. This volume increase was primarily due to increased market share with significant customers, increased demand internationally from customers in Latin America and Canada, and strong U.S. government demand for our wireless communications infrastructure products. The increases in wireless communications infrastructure net sales were partially offset by a decrease in electric T&D infrastructure net sales of $2.6 million. The electric T&D infrastructure market was affected by significant competitive pricing pressures, which resulted in a $5.4 million decrease in sales. The significant pricing pressure is the result of project delays caused by the economic downturn, which have led to fewer projects overall and increased competition for each project. Partially offsetting the decline in prices, volume was 24.0% higher in the nine months ended January 31, 2011 as a result of several large infrastructure project awards, which contributed to a $2.8 million increase in electric T&D infrastructure sales.

Gross profit

Gross profit decreased by $5.8 million, or 13.7%, from $42.4 million for the nine months ended January 31, 2010 to $36.6 million for the nine months ended January 31, 2011. $8.5 million of this decrease was directly related to higher production costs, which were partially the result of increased steel prices that we were not able to fully pass on to our customers because of the competitive pricing environment as well as an unfavorable sales mix. Additionally, gross profit was negatively impacted by $0.1 million due to lower electric T&D infrastructure sales volume. This decrease in gross profit was partially offset by an increase in gross profit of $2.8 million due to higher wireless communications infrastructure sales volume. Gross profit as a percentage of sales decreased from 22.0% for the nine months ended January 31, 2010 to 18.2% for the nine months ended January 31, 2011. The decreased gross margin for the nine months ended January 31, 2011 was mainly due to increased competitive

Table of Contents

pricing pressures, which drove lower sales volume that covered a smaller portion of our fixed direct costs and an unfavorable sales mix.

General and administrative expenses

General and administrative expenses decreased by $1.7 million, or 5.5%, from $30.9 million for the nine months ended January 31, 2010 to $29.2 million for the nine months ended January 31, 2011. This decrease was directly related to a $1.9 million reduction of amortization expense associated with intangible assets, which were fully amortized in fiscal year 2010, partially offset by increased expenses related to our wireless communications tower modification department, which began operating during fiscal year 2011.

Gain (loss) on sale of property and equipment

There were no significant gains or losses from the sale of property and equipment in the nine months ended January 31, 2010 compared to a loss of $0.2 million in the nine months ended January 31, 2011. The loss in the nine months ended January 31, 2011 related to the disposal of acid regeneration equipment at our galvanizing facility in Alvarado, Texas. Our leased facilities represented approximately 88% of our available production square footage in each of the nine months ended January 31, 2010 and 2011. In our wireless communications infrastructure reportable segment, our leased production facilities represented approximately 71% of our production capacity in each of the nine months ended January 31, 2010 and 2011. Our Bossier City, Louisiana facility, which we lease as a result of the sale-leaseback transaction consummated during fiscal 2009, constituted approximately 59% of our production capacity for our wireless communications infrastructure reportable segment in each of the nine months ended January 31, 2010 and 2011. In our electric T&D infrastructure reportable segment, our only leased facility is our Alvarado, Texas pole plant facility, which we lease as a result of the sale-leaseback transaction consummated during fiscal 2009, and which represented approximately 91% of our production capacity in the nine months ended January 31, 2010 and 2011. The facility utilization rates for our wireless communications infrastructure reportable segment were approximately 85% and 94% for the nine months ended January 31, 2010 and 2011, respectively. Utilization rates for our wireless communications infrastructure reportable segment are based on the number of units produced as a percentage of the total normal capacity of that reportable segment's production facilities. The facility utilization rates for our electric T&D infrastructure reportable segment were approximately 81% and 83% for the nine months ended January 31, 2010 and 2011, respectively. Utilization rates for our electric T&D infrastructure reportable segment are based on the pounds of steel produced as a percentage of the total normal capacity of that reportable segment's production facilities.

Income tax expense

We recorded income tax expense of $0.4 million for the nine months ended January 31, 2011, with an effective tax rate of 39.8%, compared to income tax expense of $1.5 million for the nine months ended January 31, 2010, with an effective tax rate of 34.9%. The decrease in tax expense for the nine months ended January 31, 2011 is due to lower pre-tax income.

Year Ended April 30, 2010 Compared to Year Ended April 30, 2009

Net sales

Total net sales decreased by $46.8 million, or 15.5%, from $302.1 million during the year ended April 30, 2009 to $255.3 million during the year ended April 30, 2010. The majority of this decrease was related to decreases in sales of wireless communications infrastructure products in the amount of $57.6 million. The domestic wireless communications infrastructure market was affected by a decline in order volume of $37.8 million due to weaker economic conditions. In addition to a decline in volume,

Table of Contents

steel prices have remained significantly lower in the year ended April 30, 2010, contributing to $8.3 million in lower wireless communications infrastructure sales. There was also a $9.0 million decrease in our international wireless communications infrastructure sales due to the global economic downturn and tightening of the credit markets, which have caused customers to reduce project sizes or postpone projects until funding becomes available. These reductions in net sales were partially offset by a net increase in electric T&D structure sales of $10.9 million. This increase was due to an increase in order volume of $31.7 million related to large transmission projects in late fiscal 2009 and early fiscal 2010, partially offset by decreases of $23.5 million attributable to lower steel prices and competitive pricing pressure. In addition, an increase of $2.7 million of net sales in the year ended April 30, 2010 was attributable to sales of galvanizing services to external customers. Our electric T&D infrastructure customers, which are mainly utility companies, are continuing their investment in electric T&D upgrades to improve the reliability and capacity of the electric power grid in the United States.

Gross profit

Gross profit decreased by $13.0 million, or 20.0%, from $65.1 million for the year ended April 30, 2009 to $52.0 million for the year ended April 30, 2010. $10.6 million of this decrease is directly related to lower wireless communications infrastructure product sales volume both domestically and internationally due to prevailing economic conditions. The gross margin of our CellXion operating segment was negatively impacted by the Verizon/Alltel merger consummated in late fiscal 2009, which we believe temporarily decreased its sales volumes. CellXion has a higher concentration of sales to Verizon and Alltel compared to our other wireless communications infrastructure operating segments. As a result, CellXion gross profit margins were impacted more significantly than those of our other wireless communications infrastructure operating segments, as this decrease in sales at CellXion resulted in a smaller portion of fixed costs being covered. Additionally, gross profit from electric T&D infrastructure sales decreased by $1.7 million. Increased production costs on one large multi-phase electric transmission project lowered gross profit by $1.4 million in the year ended April 30, 2010. Gross profit as a percentage of sales decreased from 21.5% for the year ended April 30, 2009 to 20.4% for the year ended April 30, 2010. The decreased gross margin for the year ended April 30, 2010 was mainly due to increased competitive pricing pressures combined with lower sales volume covering a smaller portion of our fixed direct costs.

General and administrative expenses

There was no significant change in general and administrative expenses from the year ended April 30, 2009 to the year ended April 30, 2010. Increases related to salary and benefits expenses for our electric T&D infrastructure segment as a result of increased sales volume and production were offset by cost containment efforts in our wireless communications infrastructure segment.

Goodwill and intangible asset impairment

We concluded our annual impairment test of indefinite-lived intangible assets and goodwill in the fourth quarter of fiscal 2010. The estimated fair value of one of our trade names was less than its carrying value, which resulted in a pre-tax impairment charge of $3.1 million. One of our reporting units, CellXion (which is a part of our wireless communications infrastructure reportable segment), required the second-step analysis because the estimated fair value was less than the carrying value, which resulted in a pre-tax goodwill impairment charge of $9.7 million. See "—Summary of Critical Accounting Policies and Estimates—Goodwill and Other Long-Lived Assets" below for further detail. During the year ended April 30, 2009, there were no intangible asset or goodwill impairments.

Gain (loss) on sale of property and equipment

There were no significant gains or losses from the sale of property and equipment in the year ended April 30, 2010 compared to a net loss on sale of property and equipment of $5.5 million for the year ended April 30, 2009. The loss on sale of property and equipment for the year ended April 30, 2009 primarily resulted from our August 1, 2008 sale of land, buildings and improvements located at our Bossier City, Louisiana facility and the pole plant portion of our Alvarado, Texas facility to Pole Landlord LLC, for net proceeds of $25.2 million, in order to reduce our outstanding indebtedness. As a result of the sale, our results were negatively impacted by a pre-tax loss of $6.4 million. Concurrently, we leased the properties back from Pole Landlord LLC under an operating lease with payments of $0.6 million per quarter through August 2028. In fiscal 2008, we completed our newly constructed Alvarado, Texas facility and acquired our Bossier City, Louisiana facility through the acquisition of CellXion. In a separate transaction, we received proceeds of $0.8 million, all of which was a net gain, for the sale of mineral rights at the Bossier City property.

Our leased facilities represented approximately 88% of our available production square footage in each of the years ended April 30, 2009 and 2010. In our wireless communications infrastructure reportable segment, our leased production facilities represented approximately 71% of our production capacity in each of the years ended April 30, 2009 and 2010. Our Bossier City, Louisiana facility, which we lease as a result of the sale-leaseback transaction consummated during fiscal 2009, constituted 59% of our production capacity for our wireless communications infrastructure reportable segment in each of the years ended April 30, 2009 and 2010. In our electric T&D infrastructure reportable segment, our only leased facility is our Alvarado, Texas pole plant facility, which we lease as a result of the sale-leaseback transaction consummated during fiscal 2009, and which represented approximately 94% and 91% of our production capacity in the years ended April 30, 2009 and 2010, respectively. The facility utilization rates for our wireless communications infrastructure reportable segment were approximately 88% and 66% for the years ended April 30, 2009 and 2010, respectively. Utilization rates for our wireless communications infrastructure reportable segment are based on the number of units produced as a percentage of the total normal capacity of that reportable segment's production facilities. The facility utilization rates for our electric T&D infrastructure reportable segment were approximately 93% and 90% for the years ended April 30, 2009 and 2010, respectively. Utilization rates for our electric T&D infrastructure reportable segment are based on the pounds of steel produced as a percentage of the total normal capacity of that reportable segment's production facilities.

Income tax expense (benefit)

We recorded an income tax benefit of $4.3 million for the year ended April 30, 2010, with an effective tax rate of 36.5%, compared to income tax expense of $2.7 million for the year ended April 30, 2009, with an effective tax rate of 35.8%. The decrease in the income tax expense (benefit) is primarily attributable to a decrease in taxable income of $19.5 million.

Year Ended April 30, 2009 Compared to Year Ended April 30, 2008

Net sales

Total net sales increased by $79.9 million, or 36.0%, from $222.2 million during the year ended April 30, 2008 to $302.1 million during the year ended April 30, 2009. The increase in net sales was partially attributable to a full year of operating results of CellXion, which was acquired on September 12, 2007 and contributed an additional $35.5 million of net sales in fiscal 2009. Additionally, wireless communications tower and monopole sales increased by $11.6 million, due to increased sales prices to cover higher steel costs, as well as strong demand from net sales in international markets, which contributed $3.6 million of the increase. In addition to the increases in our wireless communications infrastructure segment, we also experienced a strong sales increase in electric

Table of Contents

transmission poles in the amount of $20.7 million. This increase was due to increased selling prices due to steel pricing along with higher unit volume. The sales unit volume increase was due to improved demand in our electric T&D infrastructure segment. Electric T&D infrastructure sales unit volume increased by 18.5% in fiscal 2009 as compared with 2008. Our costs for steel escalated throughout 2009, resulting in higher costs and $27.8 million in sales price increases to our customers for the items we manufactured.

Gross profit

Gross profit increased by $16.6 million, or 34.2%, from $48.5 million for the year ended April 30, 2008 to $65.1 million for the year ended April 30, 2009. Increases in gross profit were partially attributable to a full year of operating results from the additional business attributable to the CellXion acquisition in fiscal 2008, which contributed an additional $5.6 million of gross profit, as well as increased electric T&D infrastructure sales volume, which added $5.0 million to fiscal 2009 gross profit. The gross margin (gross profit as a percent of sales) in the 2009 fiscal year was comparable to 2008. Despite rapidly rising steel prices, we were generally able to pass on these cost increases to our customers through higher selling prices to maintain gross margins. Improved gross margin in our electric T&D infrastructure segment in 2009 offset moderately weaker gross margin in our wireless communications infrastructure segment. The increases in gross margin in our electric T&D infrastructure segment were a result of $2.1 million in sales price increases that outpaced higher steel costs, combined with $5.0 million of additional sales linked to strong electric transmission pole demand. Decreases in our wireless communications infrastructure segment gross profit as a percentage of sales were attributable to several factors, including higher steel costs of $1.3 million in early fiscal 2009 that were not fully absorbed through price increases and higher wireless site construction job costs of $1.2 million associated with increased subcontractor labor.

General and administrative expenses

General and administrative expenses increased by $10.1 million, or 32.2%, from $31.2 million for the year ended April 30, 2008 to $41.3 million for the year ended April 30, 2009. The increase in general and administrative expenses is primarily attributable to the full-year effect of the CellXion acquisition contributing an additional $6.4 million, of which $1.5 million related to additional amortization of intangible assets. In addition, there were increased costs related to higher incentive compensation in the amount of $1.2 million due to improved operating results in fiscal 2009 compared to fiscal 2008; an $0.9 million increase in accounting and legal fees mainly related to acquisition arbitration costs and other corporate expenses associated with expanding our business; an $0.8 million increase in bad debt expense related to a customer bankruptcy filing; and opening our in-house galvanizing facility in Alvarado, Texas in the amount of $0.5 million.

Gain (loss) on sale of property and equipment

Net loss on sale of property and equipment was $5.5 million for the year ended April 30, 2009 compared to no significant gain or loss on sale of property and equipment for the year ended April 30, 2008. The loss on sale of property and equipment for the year ended April 30, 2009 primarily resulted from our August 1, 2008 sale of land, buildings and improvements located at our Bossier City, Louisiana facility and the pole plant portion of our Alvarado, Texas facility to Pole Landlord LLC, for net proceeds of $25.2 million, in order to reduce our outstanding indebtedness. As a result of the sale, our results were negatively impacted by a pre-tax loss of $6.4 million. Concurrently, we leased the properties back from Pole Landlord LLC under an operating lease with payments of $0.6 million per quarter through August 2028. In fiscal 2008, we completed our newly constructed Alvarado, Texas facility and acquired our Bossier City, Louisiana facility through the acquisition of CellXion. In a

Table of Contents

separate transaction, we received proceeds of $0.8 million, all of which was a net gain, for the sale of mineral rights at the Bossier City property.

Our leased facilities represented approximately 12% and 88% of our available production square footage in the years ended April 30, 2008 and 2009, respectively. In our wireless communications infrastructure reportable segment, our leased production facilities represented approximately 18% and 71% of our production capacity in the years ended April 30, 2008 and 2009, respectively. Our Bossier City, Louisiana facility, which we lease as a result of the sale-leaseback transaction consummated during fiscal 2009, constituted 59% of our production capacity for our wireless communications infrastructure reportable segment in the year ended April 30, 2009. In our electric T&D infrastructure reportable segment, our only leased facility is our Alvarado, Texas pole plant facility, which we lease as a result of the sale-leaseback transaction consummated during fiscal 2009, which represented approximately 94% of our production capacity in the year ended April 30, 2009. The facility utilization rates for our wireless communications infrastructure reportable segment were approximately 93% and 88% for the years ended April 30, 2008 and 2009, respectively. Utilization rates for our wireless communications infrastructure reportable segment are based on the number of units produced as a percentage of the total normal capacity of that reportable segment's production facilities. The facility utilization rates for our electric T&D infrastructure reportable segment were approximately 80% and 93% for the years ended April 30, 2008 and 2009, respectively. Utilization rates for our electric T&D infrastructure reportable segment are based on the pounds of steel produced as a percentage of the total normal capacity of that reportable segment's production facilities.

Income tax expense

We recorded a provision for income taxes of $2.7 million for the year ended April 30, 2009, with an effective tax rate of 35.8%, compared to a provision of $1.2 million for the year ended April 30, 2008, with an effective tax rate of 23.9%. The increase in the income tax expense and effective tax rate are primarily attributable to increased taxable income in the amount of $2.7 million. The increase in the effective tax rate was also affected by a reduction of tax credits of $0.3 million and a reduction in the domestic production deduction.

We have two reportable segments: wireless communications infrastructure and electric T&D infrastructure. We evaluate our business segments primarily on the basis of adjusted EBITDA. The segment discussion that follows provides supplemental information regarding the significant factors contributing to the changes in results for each of our business segments.

Wireless Communications Infrastructure

Three Months Ended January 31, 2011 Compared to Three Months Ended January 31, 2010

Wireless communications infrastructure reportable segment net sales for the three months ended January 31, 2011 were $50.4 million, up $7.6 million, or 17.7%, from the three months ended January 31, 2010. The wireless communications infrastructure segment was positively impacted by 9.1% higher volume generating $6.2 million in additional revenue. This increase was mainly driven by a 38.3% increase in sales unit volume of wireless communication tower and monopole sales. Domestic sales unit volume was higher due to increased market share with significant customers and strong U.S. government demand for our wireless communications infrastructure products. There was also a $0.9 million increase in our international wireless communications infrastructure sales, as a result of increased demand from customers in Latin America and Canada for our wireless communications infrastructure products. In addition to the unit volume increase, sales prices in the three months ended January 31, 2011 were higher, increasing sales by $0.5 million as a result of continued increased demand.

Segment gross profit increased by $1.5 million, or 17.4%, from $8.3 million for the three months ended January 31, 2010 to $9.8 million for the three months ended January 31, 2011. $1.7 million of this increase was directly related to 17.7% higher sales volume in the three months ended January 31, 2011. This increase was partially offset by higher production costs, which were partially the result of increased steel prices that we were not able to fully pass on to our customers because of the competitive pricing environment, which reduced gross profit by $0.3 million. Gross profit as a percentage of sales decreased from 19.5% for the three months ended January 31, 2010 to 19.4% for the three months ended January 31, 2011. The decreased gross margin for the three months ended January 31, 2011 was mainly due to increased competitive pricing pressures, which were primarily offset by higher sales volume covering a larger portion of our fixed direct costs.

Segment general and administrative expenses decreased by $1.0 million, or 13.3%, from $7.5 million for the three months ended January 31, 2010 to $6.5 million for the three months ended January 31, 2011. This decrease was related to a $0.2 million reduction of amortization expense associated with intangible assets, which were fully amortized in fiscal year 2010, as well as a $0.3 million reduction in legal expense associated with acquisition arbitration costs. Additionally, there were other expense reductions in the three months ended January 31, 2011 associated with management initiatives to increase profitability.

Table of Contents

Wireless communications infrastructure reportable segment net income (loss) increased by $2.2 million from a net loss of $0.7 million for the three months ended January 31, 2010 to net income of $1.5 million for the three months ended January 31, 2011. This segment's adjusted EBITDA increased by $2.2 million, or 113.4%, from $1.9 million for the three months ended January 31, 2010 to $4.1 million for the three months ended January 31, 2011. This increase is related to increased sales volume driven by 9.1% higher unit volume, as well as a reduction in segment general and administrative expense, slightly offset by competitive pricing pressures.

Nine Months Ended January 31, 2011 Compared to Nine Months Ended January 31, 2010

Wireless communications infrastructure reportable segment net sales for the nine months ended January 31, 2011 were $146.4 million, up $11.5 million, or 8.6%, from the nine months ended January 31, 2010. The wireless communications infrastructure segment was positively impacted by 10.6% higher volume generating $18.1 million in additional revenue. This increase was mainly driven by a 29.4% increase in sales unit volume of wireless communications tower and monopole sales. Domestic sales unit volume was higher due to increased market share with significant customers and strong U.S. government demand for our wireless communications infrastructure products. There was also a $0.3 million increase in our international wireless communications infrastructure sales, as a result of increased demand from customers in Latin America and Canada for our wireless communications infrastructure products. Partially offsetting this increase, sales prices in the nine months ended January 31, 2011 were significantly lower, reducing sales by $6.8 million as a result of continued competitive pricing pressures.

There was no significant change in segment gross profit from the nine months ended January 31, 2011 compared to the nine months ended January 31, 2010. Gross profit as a percentage of sales decreased from 21.5% for the nine months ended January 31, 2010 to 19.8% for the nine months ended January 31, 2011. The decreased gross margin for the nine months ended January 31, 2011 was mainly due to increased competitive pricing pressures, which were partially offset by higher sales volume covering a larger portion of our fixed direct costs.

Segment general and administrative expenses decreased by $1.2 million, or 5.9%, from $21.3 million for the nine months ended January 31, 2010 to $20.1 million for the nine months ended January 31, 2011. This decrease was directly related to a $1.7 million reduction of amortization expense associated with intangible assets, which were fully amortized in fiscal year 2010, offset by an increase in sales commissions due to the 8.6% increase in wireless communications infrastructure sales compared to the nine months ended January 31, 2011 and increased expenses related to our wireless communications tower modification department, which began operating during fiscal year 2011.

Wireless communications infrastructure reportable segment net income increased by $1.6 million from net income of $1.4 million for the nine months ended January 31, 2010 to net income of $3.0 million for the nine months ended January 31, 2011. This increase is due to improved sales volume as well as a reduction in amortization expense and a reduction in interest expense offset by lower margins. This segment's adjusted EBITDA decreased by $0.2 million, or 1.7%, from $11.9 million for the nine months ended January 31, 2010 to $11.7 million for the nine months ended January 31, 2011. This reduction is related to increased competitive pricing pressures as well as an increase in segment general and administrative expenses related to our wireless communications tower modification department, which began operating during fiscal year 2011, mostly offset by improved sales unit volume.

Year Ended April 30, 2010 Compared to Year Ended April 30, 2009

Wireless communications infrastructure reportable segment net sales for the year ended April 30, 2010 were $173.5 million, down $57.6 million, or 24.9%, from the year ended April 30, 2009. The domestic wireless communications infrastructure segment was affected by a $37.8 million decline in order volume by significant customers as a result of an overall weaker economy. In addition to a

Table of Contents

decline in units, steel prices were significantly lower than in the year ended April 30, 2009, reducing sales by $8.3 million. There was also a $9.0 million decrease in our international wireless communications infrastructure sales as customers reduced project sizes or postponed projects during the global recession. The decreases were due to the continued economic downturn within the wireless carrier industry, as demand from customers was weaker.

Segment gross profit decreased by $11.4 million, or 24.3%, from $46.9 million for the year ended April 30, 2009 to $35.5 million for the year ended April 30, 2010. $10.6 million of this decrease is directly related to lower wireless communications tower, monopole and shelter sales volumes, both domestically and internationally. Additionally, the gross margin of our CellXion operating segment was negatively impacted by the Verizon/Alltel merger consummated in late fiscal 2009, which we believe temporarily decreased its sales volumes. CellXion has a higher concentration of sales to Verizon and Alltel compared to our other wireless communications infrastructure operating segments. As a result, CellXion gross profit margins were impacted more significantly than those of our other wireless communications infrastructure operating segments, as this decrease in sales at CellXion resulted in a smaller portion of fixed costs being covered. Despite the 24.9% decrease in net sales for the segment, gross profit as a percentage of sales increased from 20.3% for the year ended April 30, 2009 to 20.5% for the year ended April 30, 2010. Increases in efficiency and stringent cost containment efforts including reduced direct labor hours offset the impact of decreased sales volume.

Segment general and administrative expenses decreased by $2.2 million, or 7.1%, from $30.5 million for the year ended April 30, 2009 to $28.3 million for the year ended April 30, 2010. The majority of this change is attributable to cost containment efforts in our wireless communications infrastructure segment, as well as reduced commission expense in conjunction with lower sales volumes, partially offset by $0.1 million in costs associated with new distribution centers for our wireless communications components.

Wireless communications infrastructure reportable segment net income (loss) decreased by $11.9 million from net income of $3.7 million for the year ended April 30, 2009 to a net loss of $8.2 million for the year ended April 30, 2010. This segment's adjusted EBITDA decreased by $10.7 million, or 46.3%, from $23.0 million for the year ended April 30, 2009 to $12.4 million for the year ended April 30, 2010. This decrease was the result of a $41.3 million decrease in sales volume due to general economic conditions, partially offset by cost-containment actions.

Year Ended April 30, 2009 Compared to Year Ended April 30, 2008

Wireless communications infrastructure reportable segment net sales were $231.1 million, up $58.1 million, or 33.6%, from the year ended April 30, 2008. The increase in segment net sales was partially attributable to a full year of operating results at CellXion, which was acquired on September 12, 2007 and contributed an additional $35.5 million of net sales in fiscal 2009. Additionally, wireless communications tower and monopole sales increased by $11.6 million, driven by higher steel prices. Volumes internationally increased in fiscal 2009 as a result of strong demand in Latin America adding $3.6 million in sales.

Segment gross profit increased by $9.9 million, or 26.9%, from $36.9 million for the year ended April 30, 2008 to $46.9 million for the year ended April 30, 2009. Increases in gross profit were partially attributable to a full year of operating results at CellXion, which contributed an additional $5.6 million of gross profit. Along with a 33.6% increase in our fiscal 2009 wireless communications infrastructure segment net sales, segment gross profit as a percentage of sales decreased from 21.4% for the year ended April 30, 2008 to 20.3% for the year ended April 30, 2009 as a result of several factors, including $1.3 million in higher steel costs in early fiscal 2009 that were not passed through in price increases to our customers and higher wireless site construction job costs of $1.2 million associated with increased subcontractor labor.

Segment general and administrative expenses increased by $7.2 million, or 31.0%, from $23.3 million for the year ended April 30, 2008 to $30.5 million for the year ended April 30, 2009. The

Table of Contents

increase in general and administrative expenses is primarily attributable to the full year effect of the CellXion acquisition contributing an additional $6.4 million, of which $1.5 million related to additional amortization of intangible assets, as well as higher incentive compensation due to increased sales in 2009 compared to 2008.

Wireless communications infrastructure reportable segment net income increased $0.5 million, or 15.2%, from $3.2 million for the year ended April 30, 2008 to $3.7 million for the year ended April 30, 2009. This segment's adjusted EBITDA increased by $3.6 million, or 18.3%, from $19.5 million for the year ended April 30, 2008 to $23.0 million for the year ended April 30, 2009. The increase was primarily due to sales increases in the tower and monopole product lines.

Electric T&D Infrastructure

Three Months Ended January 31, 2011 Compared to Three Months Ended January 31, 2010

Electric T&D infrastructure reportable segment net sales were $24.2 million for the three months ended January 31, 2011, up $6.2 million, or 34.3%, from the three months ended January 31, 2010. This increase was primarily the result of 55.5% higher sales unit volume due to several large infrastructure project awards contributing $9.2 million of additional electric T&D infrastructure sales. Partially offsetting this increase were continued competitive pricing pressures, resulting in a sales decrease of $3.0 million. The significant pricing pressure is the result of project delays caused by the economic downturn, which have led to fewer projects overall and increased competition for each project.

Segment gross profit increased by $0.6 million, or 14.9%, from $3.8 million for the three months ended January 31, 2010 to $4.4 million for the three months ended January 31, 2011. Gross profit was positively impacted by $1.4 million due to higher electric T&D infrastructure sales volume. Partially offsetting this increase was $0.8 million of higher production costs, which were partially the result of increased steel prices that we were not able to pass on to our customers because of the competitive pricing environment. Gross profit as a percentage of sales decreased from 21.2% for the three months ended January 31, 2010 to 18.1% for the three months ended January 31, 2011. This decreased gross margin for the three months ended January 31, 2011 was mainly due to increased competitive pricing pressures.

There was no significant change in segment general and administrative expenses from the three months ended January 31, 2011 compared to the three months ended January 31, 2010. Increases related to commission expense due to higher sales volumes were offset by cost containment efforts in our electric T&D infrastructure segment.

Electric T&D infrastructure reportable segment net income (loss) increased by $0.4 million from a net loss of $0.1 million for the three months ended January 31, 2010 to net income of $0.3 million for the three months ended January 31, 2011. This segment's adjusted EBITDA increased by $0.5 million from $1.7 million for the three months ended January 31, 2010 to $2.1 million for the three months ended January 31, 2011. The increase in net income and adjusted EBITDA related to the significant increase in sales unit volume partially offset by increased competitive pricing pressures and higher production costs.

We believe that, as evidenced by the results for the three months ended January 31, 2011, economic conditions are beginning to improve and activity and spending in the electric T&D infrastructure market will continue to increase. Compared to the average net sales for the first two quarters of fiscal year 2011, net sales increased 57.1% in the three months ended January 31, 2011. In addition, our electric T&D infrastructure gross profit for the three months ended January 31, 2011 was 39.0% higher than the combined gross profit for the first two quarters of fiscal year 2011, segment gross profit percentage increased from 10.2% for the first half of fiscal year 2011 to 18.1% for the three months ended January 31, 2011, and segment adjusted EBITDA for the three months ended

Table of Contents

January 31, 2011 increased $2.8 million compared to the combined segment adjusted EBITDA for the first two quarters of fiscal year 2011.

Nine Months Ended January 31, 2011 Compared to Nine Months Ended January 31, 2010

Electric T&D infrastructure reportable segment net sales were $55.1 million for the nine months ended January 31, 2011, down $2.6 million, or 4.5%, from the nine months ended January 31, 2010. This decrease was primarily the result of continued competitive pricing pressures, resulting in sales decreases of $5.4 million. The significant pricing pressure is the result of project delays caused by the economic downturn, which have led to fewer projects overall and increased competition for each project. Offsetting the decline in prices, sales unit volume was 24.0% higher in the nine months ended January 31, 2011 due to several large infrastructure project awards contributing $2.8 million of additional electric T&D infrastructure sales.

Segment gross profit decreased by $5.9 million, or 43.8%, from $13.4 million for the nine months ended January 31, 2010 to $7.6 million for the nine months ended January 31, 2011. $5.8 million of this decrease was directly related to higher production costs, which were partially the result of increased steel prices that we were not able to pass on to our customers because of the competitive pricing environment. Additionally, gross profit was negatively impacted by $0.1 million due to lower electric T&D infrastructure sales volume. Gross profit as a percentage of sales decreased from 23.3% for the nine months ended January 31, 2010 to 13.7% for the nine months ended January 31, 2011. This decreased gross margin for the nine months ended January 31, 2011 was mainly due to increased competitive pricing pressures combined with lower sales volume covering a smaller portion of our fixed direct costs.

Segment general and administrative expenses decreased by $0.4 million, or 4.4%, from $9.5 million for the nine months ended January 31, 2010 to $9.1 million for the nine months ended January 31, 2011. This decrease in general and administrative expenses was primarily attributable to a $0.2 million reduction of amortization expense associated with intangible assets, which were fully amortized in fiscal year 2010. Additionally, there were other expense reductions in the nine months ended January 31, 2011 associated with lower sales volume for the nine months ended January 31, 2011, as compared with the nine months ended January 31, 2010.

Electric T&D infrastructure reportable segment net income (loss) decreased by $3.7 million from net income of $1.3 million for the nine months ended January 31, 2010 to a net loss of $2.4 million for the nine months ended January 31, 2011. This segment's adjusted EBITDA decreased by $5.6 million from $7.0 million for the nine months ended January 31, 2010 to $1.4 million for the nine months ended January 31, 2011. The decrease in net income and adjusted EBITDA related to increased competitive pricing pressures and higher production costs.

Year Ended April 30, 2010 Compared to Year Ended April 30, 2009

Electric T&D infrastructure reportable segment net sales were $81.9 million for the year ended April 30, 2010, up $10.9 million, or 15.4%, from the year ended April 30, 2009. This increase was mainly due to continued market expansion and increased sales efforts, resulting in sales increases of $31.7 million due to increased volume, partially offset by a $23.5 million decrease primarily due to lower steel prices. Also included in the year ended April 30, 2010 was revenue from a large 500kV utility transmission project awarded to us in the amount of $18.2 million. Our customers, which are mainly utility companies, are continuing their investment in electric T&D upgrades to improve the reliability and capacity of the electric power grid in the United States.

Segment gross profit decreased by $1.7 million, or 9.1%, from $18.2 million for the year ended April 30, 2009 to $16.5 million for the year ended April 30, 2010. Increased production costs on one large multi-phase electric transmission project lowered gross profit by $1.4 million in the year ended April 30, 2010. Segment gross profit as a percentage of sales decreased from 25.6% for the year ended April 30, 2009 to 20.2% for the year ended April 30, 2010. The decreased gross margin for the year

Table of Contents

ended April 30, 2010 was mainly due to increased competitive pricing pressures and lower selling prices due to decreases in steel prices.

Segment general and administrative expenses increased by $2.1 million, or 19.9%, from $10.8 million for the year ended April 30, 2009 to $12.9 million for the year ended April 30, 2010. The increase in general and administrative expenses is primarily attributable to $0.7 million of increased costs related to a full year of operations at our galvanizing facility in Alvarado, Texas, as well as increased salary and benefits expenses related to our electric T&D infrastructure segment as a result of increased sales volume and production.

Electric T&D infrastructure reportable segment net income decreased $0.6 million, or 47.1%, from $1.2 million for the year ended April 30, 2009 to $0.6 million for the year ended April 30, 2010. This segment's adjusted EBITDA decreased by $3.1 million, or 28.6%, from $10.7 million for the year ended April 30, 2009 to $7.7 million for the year ended April 30, 2010. The decrease in net income and adjusted EBITDA related to increased competitive pricing pressures and lower steel prices.

Year Ended April 30, 2009 Compared to Year Ended April 30, 2008

Electric T&D infrastructure segment net sales were $71.0 million for the year ended April 30, 2009, up $21.8 million, or 44.2%, from the year ended April 30, 2008. The sales increase in our electric T&D infrastructure segment for the fiscal year ended April 30, 2009 as compared with 2008 was due to $9.5 million in price increases primarily due to higher steel costs and $11.2 million in additional sales due to increased volume. Unit sales of electric transmission and distribution pole structures to utility customers in 2009, the first full year of manufacturing operations at our Alvarado, Texas facility, were 18.9% higher compared to 2008. The increase in demand for electric T&D structures was the result of continued investment by utility companies to improve the electrical T&D infrastructure in the United States.

Segment gross profit increased by $6.7 million, or 57.8%, from $11.5 million for the year ended April 30, 2008 to $18.2 million for the year ended April 30, 2009. This increase was primarily due to increased electric T&D sales of $5.0 million, mainly attributable to increased demand for electric T&D structures. Segment gross profit as a percentage of sales increased from 23.4% in fiscal 2008 to 25.6% in fiscal 2009. The improvement in gross profit margin (gross profit as a percent of sales) in fiscal 2009 from 2008 was mainly due to improved factory performance associated with $5.0 million of higher sales and higher average sales prices combined with moderating raw material costs.

Segment general and administrative expenses increased by $2.8 million, or 35.7%, from $7.9 million for the year ended April 30, 2008 to $10.8 million for the year ended April 30, 2009. The increase in general and administrative expenses is primarily attributable to increased costs related to opening our galvanizing facility in Alvarado, Texas in the amount of $0.5 million and $0.4 million related to increased headcount to support the sales volume increase.

Electric T&D infrastructure reportable segment net income increased $0.7 million, or 126.7%, from $0.5 million for the year ended April 30, 2008 to $1.2 million for the year ended April 30, 2009. This segment's adjusted EBITDA increased by $5.2 million, or 93.2%, from $5.6 million for the year ended April 30, 2008 to $10.7 million for the year ended April 30, 2009. The improved adjusted EBITDA in fiscal 2009 as compared with 2008 related to the $21.8 million in increased sales and improved average selling prices. The increase in demand for electric T&D structures was the result of continued investment by utility companies to improve the electric T&D infrastructure in the United States.

Market Risk

We are exposed to market risk from changes in raw material prices and interest rates on borrowings. At times, we may enter into various derivative instruments to manage certain of these risks. We do not enter into derivative instruments for speculative or trading purposes.

Changes in Prices

Certain key materials we use are commodities traded in worldwide markets and are subject to fluctuations in price. The most significant materials are steel, zinc, aluminum, cement and natural gas. Over the last several years, prices for these commodities have been volatile. The volatility in these prices was due to such factors as fluctuations in supply, government tariffs and the costs of steel-making inputs. We have also experienced volatility in natural gas prices in the past several years. Natural gas is a significant commodity used in our galvanizing operations to melt zinc used in the hot-dipped galvanizing process. Our main strategies in managing these risks are a combination of fixed-price purchase contracts with our vendors to reduce the volatility in our purchase prices and sales price increases where possible to pass along changes in the price of steel and other raw materials to our customers. During the years ended April 30, 2009 and 2010, and the nine months ended January 31, 2011, we had no outstanding commodities futures contracts.

Interest Rate Risk

We are currently exposed to the market risk associated with unfavorable upward movements in interest rates. On September 18, 2007, we entered into an interest rate collar for a notional amount of $123.0 million as required under our credit agreement with Commerzbank AG to cover at least 80.0% of the original debt amount. The notional amount was reduced to $108.0 million on September 17, 2009 and the collar expired on September 17, 2010. The interest rate collar was utilized to manage interest rate exposures and was designated as a highly effective cash flow hedge. We received a variable one-month LIBOR and paid a cap rate of 5.75% and a floor of 3.80%. For the years ended April 30, 2009 and 2010, we recognized interest charges of $2.5 million and $4.1 million, respectively, related to the interest rate collar. For the nine months ended January 31, 2010 and 2011, we recognized interest charges of $3.1 million and $1.6 million, respectively, related to the interest rate collar.

Our interest rate collar was recorded at its fair value liability of $4.8 million and $1.6 million as of April 30, 2009 and 2010, respectively. An after-tax gain of $2.1 million relating to the change in fair value of the interest rate collar is included in other comprehensive loss for the year ended April 30, 2010. Our interest rate collar had a fair value of $0 at January 31, 2011, due to its expiration on September 17, 2010. An after-tax gain of $1.0 million relating to the maturing of the interest rate collar is included in other comprehensive income for the nine months ended January 31, 2011.

Liquidity and Capital Resources

We anticipate that our cash and cash equivalents on hand, our borrowing availability under our current credit agreement or our proposed new credit agreement, our short term investments, if any, and our future cash flow from operations will provide sufficient cash to enable us to meet our future operating needs, debt service requirements and capital expenditures for the foreseeable future.

As of January 31, 2011, we had cash of $4.2 million, a working capital deficit of $63.4 million, and long-term liabilities in the amount of $0.4 million, which consisted of capital lease obligations. The working capital deficit includes $120.4 million of our term loan facility classified as current liabilities due to the expiration of the credit facility on December 31, 2011. During the nine months ended January 31, 2011, operating activities resulted in net cash provided by operations of $1.7 million, compared to net cash provided by operations of $12.6 million for the nine months ended January 31, 2010. This decrease in net cash flow from operations was primarily due to inventory purchases for large, ongoing electric T&D infrastructure orders. Cash flows used in investing activities were $1.1 million for the nine months ended January 31, 2011, including $2.9 million used in capital expenditures and $1.7 million provided by the sale of property and equipment. Cash flows used in investing activities were $4.2 million for the nine months ended January 31, 2010, including $4.3 million used for capital expenditures. Net cash provided by financing activities was $1.8 million for the nine months ended January 31, 2011, resulting primarily from incremental borrowing on our credit facility. Net cash used in financing activities was $8.8 million for the nine months ended January 31, 2010, resulting primarily from the repayment of long-term debt.

As of April 30, 2010, we had cash of $1.9 million, positive working capital of $38.6 million and long-term liabilities in the amount of $110.2 million, which consisted of the long-term portion of our term loan facility and capital lease obligations. During the year ended April 30, 2010, operating activities resulted in net cash provided by operations of $17.8 million compared to $1.9 million for the year ended April 30, 2009. This increase in cash flow from operations was primarily influenced by the timing of payments to suppliers. Cash flows used in investing activities were $6.8 million for the year ended April 30, 2010, including $4.9 million used in capital expenditures and $1.9 million used for the CellXion acquisition contingent purchase price payment. Cash flows provided by investing activities were $31.2 million for the year ended April 30, 2009, including $6.9 million used for capital expenditures, offset by $26.2 million of proceeds, primarily from the sale-leaseback transaction relating to the properties in our Alvarado, Texas and Bossier City, Louisiana locations and the release of $12.0 million in cash from escrow relating to the CellXion acquisition. We used net cash in financing activities of $9.8 million for the year ended April 30, 2010, resulting primarily from the repayment of long-term debt.

We have two term loans with outstanding principal amounts as of January 31, 2011 of $54.3 million and $45.3 million, respectively, payable to Commerzbank AG (collectively, the "Commerzbank Facility"). Each of the term loans requires quarterly installments of varying amounts through December 31, 2011, with interest due monthly at a rate equal to LIBOR plus 3.25%. These term loans are secured by substantially all of our assets.

The Commerzbank Facility requires us to comply with certain financial covenants, including an interest rate coverage ratio, a leverage ratio, capital expenditure limits and an excess cash flow recapture clause. As of January 31, 2011 and for all periods presented, we were in compliance with all of the financial covenants contained in the Commerzbank Facility.

We are required to maintain an interest coverage ratio, which is calculated by dividing our trailing twelve-month EBITDA, as defined in the Commerzbank Facility, by our trailing twelve-month interest expense incurred and paid during the period, as provided in the Commerzbank Facility. The minimum allowable and actual interest coverage ratios for April 30, 2010 and January 31, 2011 were 2.75:1 and 3.05:1 and 1.75:1 and 2.32:1, respectively. We are required to maintain a leverage ratio, which is calculated by dividing our total leverage as of the end of the measurement period, including borrowings, letters of credit and capital leases, by our trailing twelve-month EBITDA, as defined in the

Table of Contents

Commerzbank Facility. The maximum allowable and actual leverage ratios for April 30, 2010 and January 31, 2011 were 4.75:1 and 4.61:1 and 8.50:1 and 7.57:1, respectively. The Commerzbank Facility provides that our non-galvanizer related capital expenditures were not permitted to exceed $3.0 million for fiscal 2009, $4.3 million for fiscal 2010 and $3.5 million for fiscal 2011. However, we are able to carryover into each fiscal year the unused amounts from the immediately preceding fiscal year. In addition, the Commerzbank Facility specifically excludes from the calculation capital expenditures for the construction of our Alvarado, Texas manufacturing and galvanizing facility, which were $4.7 million, $0 and $0 for the years ended April 30, 2009 and 2010, and the nine months ended January 31, 2011, respectively. After taking into account the carryover from prior years and the exclusion of the capital expenditures relating to the Alvarado, Texas manufacturing and galvanizing facility, we were in compliance with the capital expenditure limits set forth in the Commerzbank Facility for each of the years ended April 30, 2009 and 2010, and the nine months ended January 31, 2011. We are also required under the Commerzbank Facility to make a mandatory prepayment of principal out of our excess cash flow, as defined in the Commerzbank Facility. We made payments of $0 and $0.2 million in fiscal 2010 and the nine months ended January 31, 2011, respectively, pursuant to this provision.

The Commerzbank Facility also requires us and our subsidiaries to comply with certain non-financial covenants restricting our ability to, among other things and subject to various exceptions: (i) engage in new business activities; (ii) incur additional indebtedness; (iii) incur liens; (iv) make loans and investments; (v) declare dividends, make distributions and pay management fees; (vi) prepay, redeem or repurchase other debt; (vii) issue capital securities, unless the net equity proceeds are used to prepay loans under the Commerzbank Facility; (viii) engage in mergers, acquisitions and asset sales; (ix) sell, transfer or lease certain assets; (x) amend or otherwise alter the Corinthian Capital acquisition documents, debt agreements or our governing documents; (xi) engage in transactions with affiliates; or (xii) engage in sale and leaseback transactions. As of January 31, 2011, we were in compliance with all of the non-financial covenants contained in the Commerzbank Facility.

A breach of any of the covenants contained in the Commerzbank Facility could result in an event of default and allow the lenders to pursue various remedies, including accelerating the repayment of any indebtedness outstanding under the Commerzbank Facility. The occurrence of an event of default under the Commerzbank Facility could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Upon completion of the offering, a portion of the indebtedness under the Commerzbank Facility will be repaid with the proceeds that we receive in the offering, and we anticipate that the remainder of the indebtedness under the Commerzbank Facility will be refinanced with a new credit agreement that will be put in place upon or shortly after the completion of the offering.

We anticipate that the proposed new credit agreement will provide $100.0 million of senior credit facilities consisting of a $40.0 million revolving credit facility, which will include a $20.0 million sublimit for the issuance of standby letters of credit and a $5.0 million sublimit for swingline loans, and a $60.0 million term loan. Subject to certain terms and conditions, we expect that the proposed new credit agreement will provide that we may request, at our option so long as no default or event of default has occurred and is continuing, increases in the amount of indebtedness permitted to be outstanding under the revolving credit facility or incremental term loans up to an aggregate of $25.0 million. We expect that each such increase will be required to be in a minimum amount of $7.5 million. We further expect that all of our existing and future direct and indirect domestic subsidiaries will be guarantors under the proposed new credit agreement and the agreement will have a four-year maturity. We anticipate that the proposed new credit agreement will provide that interest will be calculated based on our total leverage ratio, and we expect the initial interest rate to be based on LIBOR plus between 225 and 325 basis points. Indebtedness under the proposed new credit agreement is expected to be secured by a first priority security interest in (i) all of the capital stock of each of our domestic subsidiaries and 65% of the capital stock of each of our foreign subsidiaries, if any, and (ii) all of our present and future assets and those of our domestic subsidiaries. The proceeds under the

Table of Contents

proposed new credit agreement may be used (i) to refinance existing indebtedness, (ii) for working capital, capital expenditures and other general corporate purposes and (iii) for certain acquisitions. We expect that, subject to certain exceptions, the proposed new credit agreement will provide that the term loan will be repaid with, among other things, 50% of excess cash flow (as defined in the proposed new credit agreement) calculated annually, when our leverage ratio (as defined in the proposed new credit agreement) is greater than 1.50x, plus 100% of proceeds from certain asset dispositions and casualty events, and proceeds from certain debt issuances.

Under the proposed new credit agreement, we expect to be subject to certain affirmative and negative covenants, including, but not limited to, (i) a maximum leverage ratio, (ii) a minimum fixed charge coverage ratio, (iii) limitations on mergers, consolidations and asset sales, (iv) limitations on investments, including share repurchases, (v) limitations on the incurrence of additional indebtedness and (vi) limitations on capital expenditures.

The terms of the proposed new credit agreement described above are subject to change. The effectiveness of the proposed new credit agreement will be subject to the execution and delivery of mutually acceptable definitive documentation as well as the satisfaction of certain conditions precedent, including the completion of the offering.

There can be no assurance that we will enter into the proposed new credit agreement. If we are unable to refinance the remaining portion of the Commerzbank Facility on terms that are acceptable to us, we will continue to operate under the Commerzbank Facility, which must be repaid in full on or before December 31, 2011.

We also have a $25.0 million line of credit with Commerzbank AG with a balance of $22.2 million at January 31, 2011, which expires on December 31, 2011. Interest is due monthly at a rate equal to LIBOR plus 3.00%. The line of credit is secured by substantially all of our assets.

Summary of Critical Accounting Policies and Estimates

The methods, estimates and judgments that we use in applying our critical accounting policies have a significant impact on the results that we report in our financial statements. Some of our accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates regarding matters that are inherently uncertain. We also have other policies that we consider key accounting policies. However, these policies typically do not require us to make estimates or judgments that are difficult or subjective.

We have identified the accounting policies and estimates listed below as those that we believe require management's most subjective and complex judgments in estimating the effect of inherent uncertainties. This section should also be read in conjunction with Note 2, "Summary of Significant Accounting Policies" in the notes to the consolidated financial statements included in this prospectus, which includes a discussion of these and other significant accounting policies.

Inventories

Inventories are stated at the lower of cost or market. Market value of inventory and management's judgment of the need for reserves encompass consideration of other business factors including physical condition, inventory holding period, contract terms and usefulness. Inventories are valued based on a weighted average cost method that approximates the first-in, first-out, or FIFO, basis.

Goodwill and Other Long-Lived Assets

Our methodology for allocating the purchase price of acquisitions is based on established valuation techniques that reflect the consideration of a number of factors including third-party appraisals. Goodwill is measured as the excess of the cost of an acquired entity over the fair value assigned to identifiable assets acquired and liabilities assumed.

Table of Contents

We have identified six reporting units for purposes of evaluating goodwill. These reporting units for purposes of evaluating goodwill correspond to our six operating segments, as the operating segment information reviewed by management does not include components of any of the operating segments at a lower level of detail. See Note 21, "Segment Reporting" in the notes to the consolidated financial statements included elsewhere in this prospectus. We perform our annual goodwill impairment tests as of the beginning of the fourth quarter, which coincides with our strategic planning process, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value.

On a quarterly basis, we consider whether there are any triggering events that would warrant an analysis of goodwill or intangible asset impairment. We did not identify a triggering event during fiscal 2010 or the nine months ended January 31, 2011 that would require an early assessment of impairment. During fiscal 2010, sales declined for CellXion. Through the first three quarters of fiscal 2010, we believed that the decline in sales would be temporary and, accordingly, there were no changes to our internal projections of future cash flows. However, in connection with our annual goodwill impairment analysis during the fourth quarter of fiscal 2010, we determined that the goodwill balance attributable to our CellXion reporting unit was impaired. This impairment was due to deterioration in the financial performance of CellXion during fiscal 2010, which resulted in revisions to our internal projections of future operating results and cash flows during the fourth quarter of fiscal 2010, the continued general economic downturn in the wireless communications industry and capital spending delays by our customers.

We use a two-step method for determining goodwill impairment. In the first step, we compare the estimated fair value of each reporting unit to its carrying value, including goodwill. If the carrying value of a reporting unit exceeds the estimated fair value, step two is completed to determine the amount of the impairment loss. Step two requires the allocation of the estimated fair value of the reporting unit to the assets, including any unrecognized intangible assets, and liabilities in a hypothetical purchase price allocation. Any remaining unallocated fair value represents the implied fair value of goodwill, which is compared to the corresponding carrying value of goodwill to compute the goodwill impairment amount.

As part of our annual impairment analysis, we determine the estimated fair value of each reporting unit. This determination includes estimating the fair value of the reporting units using both the income and market approaches. The income approach requires management to estimate a number of factors for each reporting unit, including projected future operating results, economic projections, anticipated future cash flows, discount rates and the allocation of shared or corporate items. The market approach estimates fair value using comparable marketplace fair value data from within a comparable industry grouping. In most cases, we will assess both the income and market approaches to derive the concluded fair value of each reporting unit.

The determination of the fair value of the reporting units and the allocation of that value to individual assets and liabilities within those reporting units requires us to make significant estimates and assumptions. These estimates and assumptions primarily include, but are not limited to: the selection of appropriate peer group companies; control premiums appropriate for acquisitions in the industries in which we compete; the discount rate; terminal growth rates; and forecasts of net sales, operating income, depreciation and amortization, restructuring charges and capital expenditures. The allocation requires several analyses to determine fair value of assets and liabilities, including, among others, trade names, customer relationships and property and equipment (valued at replacement cost). Although we believe our estimates of fair value are reasonable, actual financial results could differ from those estimates due to the inherent uncertainty involved in making such estimates. Changes in assumptions concerning future financial results or other underlying assumptions could have a significant impact on either the fair value of the reporting units, the amount of the goodwill impairment charge, or both.

Table of Contents

We concluded our annual impairment test of goodwill in the fourth quarter of fiscal 2010, and five of the six reporting units had fair values that exceeded their respective carrying values by a substantial margin. One of our reporting units, CellXion (which is a part of our wireless communications infrastructure reportable segment), required the second-step analysis because the estimated fair value was less than the carrying value, which resulted in a goodwill impairment charge of $9.7 million.

Our CellXion reporting unit had $20.3 million of goodwill allocated to it as of April 30, 2010 prior to the impairment. The assumptions utilized to determine the fair value of this reporting unit were consistent with the methods outlined above. After giving effect to the impairment charge, this reporting unit has $10.6 million of goodwill remaining on the balance sheet as of April 30, 2010 and January 31, 2011.

We perform impairment tests of indefinite-lived intangible assets on an annual basis or more frequently in certain circumstances. Intangible assets having indefinite useful lives are not amortized into results of operations, but instead are reviewed at least annually for impairment. If the recorded value of the intangible assets having indefinite useful lives is determined to exceed their fair value, the asset is written down to fair value and a charge is taken against the results of operations in that period. We consider factors such as historic profitability and discounted future cash flows to determine whether the value of the assets are impaired.

We evaluate the recoverability of other long-lived assets, including property and equipment and certain identifiable intangible assets, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Factors considered important that could trigger an impairment review include significant underperformance relative to historical or projected future operating results, termination or renegotiation of a significant contract, significant changes in the manner of use of the assets or the strategy for the overall business, a significant decrease in the market value of the assets or significant negative industry or economic trends. When we determine that the carrying amount of long-lived assets may not be recoverable based upon the existence of one or more of the indicators, the assets are assessed for impairment based on the estimated future undiscounted cash flows expected to result from the use of the asset and its eventual disposition. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment loss is recorded for the excess of the asset's carrying amount over its fair value.

We concluded our annual impairment test of indefinite-lived intangibles in the fourth quarter of fiscal 2010. The estimated fair value of one of our trade names was less than its carrying value, which resulted in an impairment charge of $3.1 million. This impairment charge was recorded on our statement of operations in the fourth quarter of fiscal 2010. After giving effect to the impairment charge, this reporting unit has $5.2 million of trade name intangible assets remaining on the balance sheet as of April 30, 2010. We believe the remaining carrying value is recoverable as we continue to sell products under this trade name that generate sufficient cash flow to support the carrying value.

No other asset groups were identified as impaired as a result of the annual impairment tests.

Share-Based Compensation

We measure compensation for share-based awards based on the estimated fair values at the grant date for equity-classified awards and the recognition of the related compensation expense over the appropriate vesting period. Compensation expense is based, among other things, on: (i) the classification of an award as either an equity or a liability award; (ii) assumptions relating to fair value measurement such as the value of our stock and volatility, the expected term of the award and forfeiture rates; and (iii) whether performance criteria, if any, have been met. We use both internal and external data to assess compensation expense. Changes in these estimates based on factors such as market volatility or employee behavior, such as terminations or exercise of awards, could significantly impact share-based compensation expense in the future.

Revenue Recognition

Revenue is generally recognized when the product is shipped and risk of loss is transferred. At times, our customers experience delays due to weather, zoning approvals and similar circumstances, and request that we hold their inventory. In these situations, we recognize revenue for our products prior to the time it is shipped if each of the following bill and hold conditions are met:

•: the risks of ownership have passed to the customer;
•: the customer has a fixed commitment to purchase the goods;
•: the customer, not us, has requested that the shipment of the product be delayed and that the transaction be on a bill and hold basis;
•: there is a fixed schedule for delivery of the product;
•: we have not retained any specific performance obligations with respect to the product, such that the earnings process is not complete;
•: the ordered product has been segregated from our inventory and is not subject to being used to fill other orders;
•: the product is complete and ready for shipment; and
•: the customer agrees to pay for the goods under our standard credit terms.

In some instances, we enter into multiple-element revenue arrangements, which may include a combination of installation services, including the installation of wireless communications towers and/or wireless equipment shelters. On an annual basis, installation service revenue has represented less than 10% of our total revenue. Revenue from contracts with multiple-element arrangements is recognized as each element is earned based on the relative fair value of each element, provided that the delivered elements have value to customers on a stand-alone basis. Amounts allocated to each element are based on its objectively determined fair value, such as the sales price of the product or service when it is sold separately. Each element is generally completed within less than one month, resulting in completion of the wireless site within less than three months. There is no right of return once the product has been delivered and the service has been performed.

Income Taxes

We utilize the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities represent the future tax consequences of the difference between the financial statement carrying amounts of the assets and liabilities versus the tax basis of the assets and liabilities. Under this method, deferred tax assets are recognized for deductible temporary differences, and operating loss and tax credit carryforwards. Deferred tax liabilities are recognized for taxable temporary differences. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The impact of tax law changes on deferred tax assets and liabilities is recognized in the year that the change is enacted.

Income tax provisions for interim periods are based on estimated annual income tax rates, adjusted to reflect the effects of any significant infrequent or unusual items that are required to be discretely recognized within the current interim period.

We have indefinite long-lived intangible assets consisting of goodwill, which are not amortized for financial reporting purposes. However, the expense related to the amortization of these assets is tax-deductible, and therefore the assets are amortized for income tax purposes. As a result, deferred income tax expense and deferred income tax liabilities arise as a result of the tax-deductibility of these indefinite long-lived intangible assets. The resulting deferred tax liability, which is anticipated to continue to increase over time, has an indefinite life, resulting in what is referred to as a "naked tax credit." This deferred tax liability could remain on our balance sheet indefinitely unless there is an

Table of Contents

impairment of the related assets for financial reporting purposes, or the businesses to which the assets relate are to be disposed of. As tax goodwill that was created as a result of our acquisition completed during fiscal 2008 continues to be amortized through the nine months ended January 31, 2011, the naked credit for these deferred tax liabilities continues to increase thus decreasing the tax benefit.

We evaluate the need for a valuation allowance on the net amount of deferred tax assets (excluding the deferred tax liability for the naked credit), based on the likelihood that the deferred tax asset will be realized. No valuation allowance has been established because, in the opinion of management, it is more likely than not that the deferred tax assets will be realized. In order of importance, the evidence that was considered in determining the need for a valuation allowance was taxable income in carryback years, historical evidence of taxable income and estimated future taxable income in early future years, future reversals of taxable temporary differences, and any tax planning strategies that may be implemented to prevent the potential loss of income tax benefits. We will continue to evaluate the need for a valuation allowance at each reporting period.

Changes in, among other things, income tax legislation, statutory income tax rates or future taxable income levels could materially impact our valuation of income tax assets and liabilities and could cause our income tax provision to vary significantly among financial reporting periods.

We recognize a tax position in our financial statements when it is more likely than not that the position would be sustained upon examination by tax authorities. This recognized tax position is then measured against the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement and a reserve representing the difference is established. Although management believes that our estimates are reasonable, the final outcome of uncertain tax positions may be materially different from that which is reflected in our historical financial statements. We adjust such reserves upon changes in circumstances that would cause a change to the estimate of the ultimate liability, upon effective settlement or upon the expiration of the statue of limitations, in the period in which such event occurs. Uncertain tax positions require determinations and estimated liabilities to be made based on provisions of the tax law which may be subject to change or varying interpretation. If our determinations and estimates prove to be inaccurate, the resulting adjustments could be material to our future financial results.

In addition, we operate within multiple taxing jurisdictions and may be subject to audits in those jurisdictions. These audits can involve complex issues and may require an extended period of time for resolution. In management's opinion, adequate provisions for income taxes have been made.

Leases

On August 1, 2008, we sold land, buildings and improvements located at our Bossier City, Louisiana, and Alvarado, Texas facilities, and concurrently leased the properties back under an operating lease. On June 16, 2010, we sold and leased back an additional building at our Alvarado, Texas facility. At the time of the sale-leaseback transactions, we considered the accounting guidance prescribed by ASC 840-40: Sale-leaseback transactions ("ASC 840"), to ascertain whether the transactions qualified for sale-leaseback accounting treatment. The criteria were assessed first to determine if sale-leaseback accounting treatment was appropriate, and second, the appropriate classification of the lease as an operating lease or capital lease. Under ASC 840, sale-leaseback accounting shall be used by a seller-lessee only if a sale-leaseback transaction includes all of the following: (a) a normal leaseback; (b) payment terms and provisions that adequately demonstrate the buyer-lessor's initial and continuing investment in the property; and (c) payment terms and provisions that transfer all of the risks and rewards of ownership as demonstrated by the absence of any other continuing involvement by the seller-lessee. Since all of the above criteria were met, we determined that sale-leaseback accounting was appropriate. We then assessed the appropriate classification of the lease as an operating lease or capital lease. We considered the guidance outlined in ASC 840-10-25-1: Leases, and determined that all four criteria were satisfied to classify this transaction as an operating lease. In summary, the criteria were met as follows: (a) transfer of ownership does not revert to us

upon termination of the lease; (b) the lease does not contain a bargain purchase option; (c) the 20-year lease term does not equal or exceed 75% of the estimated useful life of the facility (which is approximately 40 years); and (d) the present value of the future minimum lease payments under the lease is not equal to or greater than 90% of the fair value of the leased asset. In determining the appropriate interest rate for the fourth operating lease criterion, we used the weighted average implicit interest rate from the lessor of 9.7% to determine the present value of the future minimum lease payments, as this rate was lower than the incremental borrowing rates available to us at the time of lease inception, as required under ASC 840: Leases.

Off-Balance Sheet Transactions

We have entered into certain off-balance sheet arrangements in the ordinary course of business that result in risks not directly reflected in our balance sheets. Our significant off-balance sheet transactions include liabilities associated with non-cancelable operating leases for property and equipment, letter of credit obligations and surety guarantees entered into in the normal course of business. We have not engaged in any off-balance sheet financing arrangements through special purpose entities.

Leases

Letters of Credit

As of January 31, 2011, we had four standby letters of credit outstanding. The first letter of credit is for $0.2 million and secures our obligations under our workers' compensation insurance policy. This letter of credit expires on November 2, 2011. The second letter of credit is for $0.2 million and secures our obligations to perform delivery of material under a contract with a customer. This letter of credit expired on March 31, 2011. The third letter of credit is for $0.1 million and secures our obligation to perform delivery of material under a contract with a customer. This letter of credit expires on December 22, 2011. The fourth letter of credit is for $2.2 million and secures our obligations to perform delivery of material under a contract with a customer. This letter of credit expires on November 30, 2011. No amounts have been drawn or are expected to be drawn under any of these letters of credit.

Surety Bonds

Many of our customers, particularly in connection with new construction, require us to post bid, performance and payment bonds issued by a financial institution known as a surety. These bonds provide a guarantee to the customer that we will perform under the terms of a contract and that we will pay subcontractors and vendors. If we fail to perform under a contract or to pay subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. We must reimburse the surety for any expenses or outlays it incurs. We currently have sufficient bonding capacity. To date, we have not been required to make any reimbursements to the surety for bond-related costs. We believe that it is unlikely that we will have to fund significant claims under our surety arrangements in the foreseeable future.

Capital Expenditures

Over the last few years, we have spent a significant amount of capital on property and equipment. We believe that our investment in property and equipment will reduce our costs and improve our margins over the long term, although we cannot assure you that it will. We will continue to rely on leases for non-specialized equipment, such as lift trucks.

We incurred capital expenditures of $4.3 million and $2.9 million in the nine months ended January 31, 2010 and 2011, respectively. We incurred capital expenditures of $23.1 million, $6.9 million and $4.9 million in the years ended April 30, 2008, 2009 and 2010, respectively. The large capital expenditures in 2008 related to the construction of our manufacturing and galvanizing operations at our Alvarado, Texas facility. We expect aggregate capital expenditures of $3.5 million in fiscal year 2011, primarily for equipment. Our credit agreement currently limits capital expenditures to $6.5 million in fiscal year 2011 plus carryover of unused amounts from the prior year. In addition to these annual limits, the incremental capital expenditures for the expansion of the Alvarado, Texas facility were approved by the lender. We intend to fund our capital expenditures primarily from operating cash flow and, depending on working capital and other requirements, our revolving line of credit, capital leases and, in some cases, vendor financing.

Contractual Obligations

As of January 31, 2011, our future contractual obligations for the last three months of our 2011 fiscal year and for the fiscal years ended April 30 were as follows:

INDUSTRY

Wireless Communications Infrastructure

According to TIA, capital expenditures on wireless infrastructure equipment were $13.7 billion in 2010. The wireless telecommunications industry consists of carriers that provide telephone, Internet, data and other services to customers through the transmission of signals over networks of cell radio towers. The signals are transmitted through antennas directly to customers, who use wireless devices, such as cell phones, mobile computers and other wireless devices, to receive, interpret and send information. A significant component of this market consists of companies that provide cellular phone service, which have grown rapidly over the past decade. Another component consists of providers that deliver mobile Internet and data services to individuals with Internet-enabled cellular phones, hand-held wireless devices and computers. According to TIA, between 2002 and 2010, the estimated number of wireless subscribers in the United States increased from 134.6 million to 292.8 million, and is projected to rise to 322.0 million in 2014.

After years of industry consolidation, the top four WSPs are now AT&T, Sprint, T-Mobile and Verizon. Customers demand broader coverage areas, fewer dropped calls and advanced networks to support voice and data services for increasingly popular wireless devices, such as smart phones, tablets, netbooks and other wireless devices. TIA reports that, in recent years, wireless telecommunications carriers have invested heavily in the deployment of new technologies and the expansion of their networks to allow faster data transmission and better Internet access, in an effort to make them more competitive with wired Internet carriers. TIA projects that wireless infrastructure equipment spending will total an estimated $17.5 billion in 2014, up from $13.7 billion in 2010, a 6.3% compound annual growth rate.

According to publicly available industry reports, wireless networks operate on a grid that divides a geographic area into smaller cell sites, each of which can cover from a few city blocks to up to 250 square miles. Within each cell site, there is a base station consisting of an antenna and other radio equipment. The wireless antenna in each cell site links callers to the local telephone network, the Internet or another wireless network.

In densely populated areas, space constraints require footprints for cell sites to be smaller, resulting in an increased number of monopoles, alternative structures and the installation of additional antennas on existing structures, many of which will require modifications. In areas with fewer space constraints, such as suburban and rural markets, guyed and self-supporting towers can be deployed. However, even in those markets, particularly where aesthetics are a key consideration, customers may prefer monopoles and stealth or camouflage structures. Based on a publicly available industry report, depending on the location, we estimate that up to 30% of new cell sites will require the construction of a new tower or monopole, and nearly all cell sites will require enclosures for network equipment. We supply a broad suite of wireless communications infrastructure products, including guyed and self-supporting towers, monopoles, shelters and ancillary components, as well as complementary services, including engineering, equipment integration, construction, third-party logistics and turnkey project management.

In many cases, wireless carriers lease antenna space on multi-tenant cell sites from tower management companies such as American Tower Corporation, Crown Castle International Corp., Global Tower Partners and SBA Communications Corporation. Tower management companies either own these cell sites or operate them pursuant to long-term lease arrangements. Tower management

companies also provide site acquisition, zoning and permitting services. We provide towers, monopoles, shelters and related products and services to both wireless carriers and tower management companies.

According to publicly available industry reports, in high-density areas, tower management companies are under increasing pressure from municipalities to co-locate antennae on existing structures before building towers on new sites. Co-location creates demand for structural modifications and additional enclosures per cell site as network equipment is housed individually at the base of the structure. We believe that incremental tenants strain existing infrastructure and have created a market for tower and monopole structural modification, reinforcement and replacement.

According to TIA, approximately 29,000 new cell sites will be added each year through 2014. This growth is driven primarily by: (i) increasing wireless device penetration; (ii) increasing data usage; (iii) consumer demand for higher quality of service; and (iv) the continued build-out of advanced networks, including 3G and 4G wireless networks.

Increasing Wireless Device Penetration

The United States remains an underdeveloped wireless market as wireless penetration (defined as the number of wireless subscriptions as a percentage of the total population) lags that of other developed countries. As wireless carriers continue to expand their subscriber base through broadened product and service offerings, U.S. wireless penetration is projected to increase. According to TIA, wireless penetration in the United States was approximately 94% in 2010 and is expected to reach 99.9% by 2014. Since wireless device capability now extends significantly beyond voice service, consumers are increasingly likely to upgrade to the next generation of wireless data devices, including smart phones, tablets, readers, mediapads, netbooks, smartbooks, digital cameras and other devices.

According to TIA, U.S. smart phone sales increased from 1.8 million units in 2003 to 54.0 million units in 2010, representing a compound annual growth rate of 62.6%. TIA reports that the percentage of wireless device unit sales represented by smart phones increased from 21.8% in 2008 to 37.5% in 2010, and is projected to reach 54.9% by 2014. Since TIA expects unit sales of all wireless devices to increase by a compound annual growth rate of 3.7% from 2011 to 2014 and the percentage of wireless device unit sales represented by smart phones is also increasing, there is considerable room for additional growth of smart phone sales. TIA reports that smart phone sales are expected to be 91.4 million units per year by 2014, representing a projected compound annual growth rate of 14.1% from 2010. Data-rich services such as music downloads, video streaming, GPS-enabled applications and additional content downloads constantly interact with the network and increase the need for more capacity. In order to meet bandwidth demands and provide high-quality data services across their networks, industry experts expect that carriers will need to add cell sites to boost capacity, which we believe will continue to drive an increasing demand for towers, monopoles, shelters and other products and services that we provide.

Cell phones continue to replace traditional wireline communications services as the primary communication device for end users in the United States, as 26.6% of U.S. households had only cell phones as of June 2010, an increase from just 13.6% in June 2007, according to publicly available industry reports. This trend has led to a steady increase in wireless minutes of use as customers utilize cell phones for a greater portion of their daily communication.

Increased wireless penetration, the demand for data-rich services and rising frequency of use each increase throughput and add pressure to network capacity, which has led wireless carriers to continue to expand investment in network infrastructure. According to TIA, between 2001 and 2010, the number of cell sites in the United States increased from 127,540 to 273,000, an 8.8% compound annual growth rate. As more users utilize a network simultaneously, we believe wireless carriers will continue to expand investment in network infrastructure, including the addition of towers, monopoles, shelters and other products and services that we provide.

Increasing Data Usage

Wireless data is one of the largest growth drivers for wireless carriers. According to TIA, spending for wireless data services increased from $6.9 billion in 2005 to $54.0 billion in 2010, a 50.9% compound annual growth rate. TIA expects spending on wireless data services to grow to $107.0 billion in 2014, a compound annual growth rate of 18.6% from 2010. According to publicly available industry reports, the first wireless communications networks were primarily built for voice and short messaging services. As TIA notes, the throughput of those networks was not designed to provide the bandwidth required for 3G and 4G wireless data devices and their high-bandwidth, data-intensive applications, such as enhanced video and picture sharing, fast web browsing, streaming video and large file downloading. Further, TIA reports that these new wireless data devices and the demand for high-bandwidth, data-intensive applications and services have already created a significant strain on network capacity. In order to increase network capacity, we believe carriers will add cell sites and towers, which we expect will require considerable capital expenditures for wireless infrastructure.

Consumer Demand for Higher Quality of Service

According to publicly available industry sources, continued growth of the wireless communications infrastructure industry is driven in part by consumer demand for quality of service, which is primarily a function of coverage and capacity. Coverage represents the geographic area covered by a wireless network. Wireless network coverage is determined by the strength of the signal, which, in many cases, must penetrate obstacles, such as buildings. As such, higher-density areas require additional infrastructure to provide equivalent coverage. The number of signals passed through a network increases with (i) greater penetration and subscriber growth, (ii) increased session duration and (iii) greater frequency of use. According to TIA, to achieve higher throughput, carriers must continually expand network capacity. Capacity is determined by the amount of spectrum that can be shared by simultaneous users of the network. Increasing demand for high-bandwidth data services strains existing network capacity.

As TIA notes, there is an increased need to meet consumer demand for improved quality of service and to enable wireless carriers to distinguish themselves from one another, which we believe will cause carriers to continue to invest in wireless network infrastructure. According to TIA, wireless networks require consistent and significant capital expenditures to expand wireless network coverage areas and enhance the capacity of existing infrastructure, which we expect will result in increased demand for our products.

Continued Build-out of Advanced Networks

According to TIA, increased wireless data usage and wireless device penetration and rising demand for higher quality of service have spurred the development of 3G and 4G wireless networks, which are expected to increase network infrastructure requirements. Additionally, TIA reports that between 2001 and 2010, the number of cell sites in the United States increased from 127,540 to 273,000 and is expected to continue to grow at a compound annual growth rate of 9.1% from 2010 to 2014, reaching 387,000 cell sites. In recent years, the major carriers have deployed 3G networks, primarily in major cities, to support these demands. As carriers continue to deploy 3G networks in additional markets, TIA reports that carriers are also focused on adding another layer of wireless infrastructure to support the development of 4G wireless networks, such as Long Term Evolution, or LTE, and Worldwide Interoperability for Microwave Access, or WiMax. However, WiMax's data-centric nature makes it poorly suited to replace mobile voice networks, and therefore existing wireless networks continue to be necessary and will also require increased coverage and capacity. In addition to traditional wireless providers, LTE has gained support from the mobile satellite provider LightSquared Company. Under its agreement with the FCC, LightSquared will be permitted to build a satellite-only, terrestrial-only or integrated satellite-terrestrial service, provided that the network covers 100 million

Table of Contents

people by 2012, 145 million by 2013 and 260 million by 2015. LightSquared expects to install 40,000 base stations to provide this coverage. Both LTE and WiMax represent new wireless technologies and will require new cell sites and infrastructure build-out nationwide. As a result, we believe the demand for towers, monopoles, shelters and other products that we provide will increase.

Electric T&D Infrastructure

The electric transmission and distribution industry is comprised of investor-owned utilities, municipal utilities, cooperatives, federally-owned utilities, independent power producers and independent transmission companies that engage in some or all of three distinct functions: electric generation, transmission and distribution. The electric T&D infrastructure, sometimes referred to as the grid, is the network of towers, transmission lines, substations, poles, distribution lines and other equipment that connects and delivers power from generators to residential, commercial and industrial end users. According to publicly available industry reports, the U.S. electric power grid includes approximately 283,000 miles of transmission lines, over two million miles of distribution lines and approximately 70,000 high voltage substations, serving 300 million customers. Electric transmission refers to power lines, substations and related equipment through which electricity is transmitted over long distances at high voltages (over 69 kilovolts) that connect the high-voltage transmission infrastructure to local distribution networks. The number of electric transmission poles per mile can range from 4 (highest voltages) to 25 (lowest voltages) per mile. Electric distribution refers to the local municipal, cooperative or utility distribution network, including associated substations, that provides electricity to end users over shorter distances.

We believe that we are the third-largest participant in the U.S. electric T&D infrastructure industry, based on management's estimates of pole revenues in the industry, and that the largest and second-largest participants in the industry have significantly greater revenues than we do.

According to a National Council on Electricity Policy report, the existing electric T&D infrastructure has been continually expanded over the last century and requires ongoing maintenance as well as upgrades and extensions to support electricity demand, manage power line congestion, avoid delivery failures and connect new generation sources to end users. During this development, electric transmission towers, poles and other structures have shifted from predominantly wooden structures to stronger, longer-life steel structures that can be built higher, carry more lines and support higher voltage. We manufacture steel towers, poles and substation structures for end customers.

We believe transmission mileage will grow to meet demand and reduce congestion. According to the NERC 2008 Long-Term Reliability Assessment, NERC projects that the total number of transmission miles in the United States will increase by 9.5% from 2007 to 2017.

Increasing Demand for Reliable Power Delivery

Growth in the electric T&D infrastructure industry is driven by the fundamental growth in electric power demand. According to EIA, between 1980 and 2006, total electricity use in the United States increased by approximately 80%, and EIA projects continued consistent growth in demand for electricity in each of the commercial, residential and industrial sectors for the foreseeable future. EIA forecasts that total electricity use in the United States will increase by approximately 25% from 2008 to 2035. According to publicly available industry reports, this increase is driven by population growth, economic expansion, increasing dependence on computing power throughout the economy and the proliferation of electrical devices in the home. For example, a U.S. Environmental ENERGY STAR report to Congress concluded that servers and data centers have become one of the largest users of electricity in the United States. According to this report, power consumption by servers and data centers doubled between 2000 and 2006, and U.S. energy consumption by servers and data centers could nearly double again by 2011 according to estimates by the U.S. Environmental Protection

Table of Contents

Agency. Based on studies conducted by the American Society of Civil Engineers and the DOE, we believe that this increase in electricity demand will require considerable investment in electric T&D infrastructure to improve the efficiency of existing systems and expand the overall electric power grid.

According to the Edison Foundation, the U.S. electric utility industry will require a total infrastructure investment of $1.5 trillion to $2.0 trillion by 2030. As part of this investment, the Edison Foundation projects total investment in T&D infrastructure of $879.3 billion over that period.

Aging and Unreliable Electric Power Infrastructure

According to the DOE, the U.S. electric infrastructure system is aging, inefficient, congested and incapable of meeting future U.S. energy needs without operational changes and substantial capital investment over the next several decades. 70% of transmission lines and transformers are 25 years or older and 60% of circuit breakers are more than 30 years old, according to DOE.

According to EEI, investment in electric transmission infrastructure declined from 1980 to 1999, during which time, according to the U.S. Energy Information Administration, electricity consumption increased by approximately 58%, resulting in increased grid congestion and power outages. These outages can be severe and highly disruptive, such as the rolling blackouts in California during 2001 and the August 2003 blackout that disrupted electricity service for 50 million customers in the United States and Canada. The DOE has estimated that power disturbances cost the economy from $25.0 billion to $180.0 billion annually.

According to EEI, members of EEI were expected to spend $11.1 billion annually on transmission projects in 2010, up from $5.7 billion in 2004. According to NERC, additional investment in the electric T&D infrastructure will help ensure the reliability of the electric T&D system and reduce transmission congestion. We believe that spending levels for electric T&D infrastructure will continue to increase as utilities work to address infrastructure maintenance requirements.

Increased Focus on Wind and Other Renewable Power Sources

We believe that the increased focus on renewable energy also should promote growth in electric T&D investment as transmission infrastructure must be developed to reliably integrate renewable energy sources like wind, solar, geothermal, hydrogen and biomass with the broader electric power grid. NERC and EEI note that, since most sources of renewable power are located far from urban demand centers, substantial infrastructure investments are expected to be required to transport electricity to the grid. We believe that, since renewable generation sources are generally smaller than traditional fossil fuel plants, a greater number of units will need to be built to meet the same generation capacity, requiring additional connections to the grid. According to publicly available industry reports, global spending on renewable energy projects is projected to increase from $55.0 billion in 2006 to $325.1 billion by 2018. From 2002 through 2009, according to an American Wind Energy Association, or AWEA, report, wind energy generation capacity grew from 4,563 MW to 35,086 MW at a compound annual growth rate of 33.8%.

According to publicly available industry sources, currently, 29 states, the District of Columbia and Puerto Rico have adopted mandatory Renewable Portfolio Standards programs that require a certain percentage of electric power to come from renewable sources programs, with targets ranging from 5% to 40% for target dates between 2013 and 2025. Seven other states have enacted non-binding RPS-like goals.

On June 26, 2009, the U.S. House of Representatives approved H.R. 2454—the American Clean Energy and Security Act of 2009. This comprehensive clean energy and climate change legislation is intended to cut greenhouse gas emissions, create new clean energy jobs and enhance U.S. energy independence. In addition to a "cap-and-trade" program, the bill also sets forth a federal

Table of Contents

combined efficiency and renewable electricity standard known as CERES. Under CERES, utilities would be required to submit federal renewable electricity credits or document electricity savings that, in total, are equal to 6% of their electricity sales by 2012, a requirement that would increase to 20% by 2020. The prospects for and timing of enactment of the bill into law are uncertain.

Texas, which, according to AWEA, is the state that has installed the greatest amount of wind energy capacity, has implemented a program that will significantly expand the state's wind power generation. In 2005, Texas created Competitive Renewable Energy Zones, or CREZ, which are defined geographic areas in the state suitable for the development of renewable energy resources, principally wind power. According to the Electric Reliability Council of Texas, a private industry group subject to oversight by the Public Utility Commission of Texas and the Texas legislature, the CREZ initiative will expedite construction of $5.0 billion in transmission lines to move 18,000 MW of renewable generation to the more populous portions of Texas. As part of the Texas program, a group of companies certified to build electric transmission facilities in Texas announced in September 2008 that they would jointly file a detailed proposal with the Public Utility Commission of Texas for the construction of electric transmission infrastructure. Publicly available industry sources note that the Texas proposal outlines the construction or upgrading of 2,400 miles of 345-kV transmission lines at a cost of $4.9 billion.

Other Legislative Developments

The U.S. government has directed significant efforts towards the modernization and improvement of the U.S. electric grid. These legislative developments continue to promote growth in electric T&D infrastructure investment by encouraging electricity providers to expand capacity and relieve grid congestion.

The Energy Act outlined the establishment of mandatory electric grid reliability standards and created incentives to increase electric T&D infrastructure investments. The Energy Act was established under the jurisdiction of the FERC, which is responsible for enforcing reliability standards for the bulk power system. The Energy Act promotes new investment in transmission infrastructure through (i) tax credits and other financial incentives and (ii) the easing or elimination of state and local siting processes that can slow the construction of new transmission networks through the creation of National Interest Electric Transmission Corridors. According to NERC, necessary transmission facilities will require the construction of more than double the average number of transmission miles constructed over any five-year period since 1990.

ARRA increased focus on the deliverability and reliability of electricity transmission, dedicating substantial funds to energy-related spending and tax credits, $4.5 billion of which has been allocated to improve electricity delivery and energy reliability.

Our electric T&D infrastructure reportable segment supplies a broad line of electric transmission and distribution poles and structures, including transmission structures, wood pole equivalents and substation structures. These products are essential for the maintenance, upgrade and expansion of the aging U.S. electric T&D grid and enable our customers to meet increasing demands for reliable power delivery. Since the construction of our purpose-built, state-of-the-art manufacturing and galvanizing facility in Alvarado, Texas in 2007 and 2008, we have become a leading provider of electric T&D structures in the United States, based on management's estimates of pole revenues in the industry. We serve key electric utilities and regional transmission organizations such as Duke Energy Corporation, Georgia Transmission Corporation, PacifiCorp and Salt River Project. We believe that our Alvarado, Texas facility gives us a cost advantage over many of our competitors that do not have manufacturing and galvanizing operations located in the same facility. The primary advantage of having our own galvanizing facility located on the same premises as our manufacturing facility is the cost savings that we realize by not having to ship the heavy steel structures we produce to another site for galvanizing or pay a third-party vendor for galvanizing services. Our electric T&D infrastructure segment revenue, net income and adjusted EBITDA for the fiscal year ended April 30, 2010 were $81.9 million, $0.6 million and $7.7 million, respectively. For the nine months ended January 31, 2011, our electric T&D infrastructure segment revenue, net loss and adjusted EBITDA were $55.1 million, $2.4 million and $1.4 million, respectively.

We were founded in 1977 as Sabre Communications Corporation, with an initial focus on providing high-frequency antennas and support structures throughout the Midwest region of the United States. In the 1980s, we shifted our focus towards the design and fabrication of towers and support structures for the communications industry. Through the 1990s, we experienced considerable growth as we built strong relationships with leading communications companies and broadened our market presence across the entire United States. We diversified our communication structures offerings in 1999 when we began to offer wireless monopoles. In 2001, we made the strategic decision to further diversify our business by entering the electric T&D infrastructure market. In 2007 we acquired CellXion, which has enabled us to expand our wireless communications infrastructure segment to include the shelters critical to the protection of valuable wireless communications equipment.

We are currently controlled by Corinthian Capital. In 2006, Sabre Communications Holdings, Inc., which was owned by Corinthian Capital and certain other investors, acquired Sabre Communications Corporation. In 2007, Sabre Industries, Inc., a newly formed Delaware corporation, succeeded to Sabre Communications Holdings, Inc. in a reorganization transaction.

Table of Contents

positioned to outbid our competition while maintaining strong profit margins, product quality, rapid response and reliable delivery.

Our manufacturing focus is on the design and engineering of steel structures, fabrication and welding of structures and sub-components, and the kitting and quality testing of steel structures for use in the wireless communications and electric T&D infrastructure markets. We manufacture all of our products to customer specifications utilizing a variety of custom and standardized materials. To improve margins and streamline the custom manufacturing of each tower, we have invested in standardizing our design and manufacturing procedures. The kitting of standardized components shortens production lead times, reduces inventory shortages and eases installation requirements for customers. Our production rationalization measures have optimized our labor force and production capabilities, effectively transitioning us to a continuous mode of production rather than that of a custom-job shop.

We design, engineer and manufacture electric transmission structures, wood pole equivalents, substation structures and wireless monopoles at our Alvarado, Texas facility. In 2007 and 2008, we invested more than $32 million in our Alvarado facility, which includes one of North America's largest and most efficient galvanizers. Our 42,000 square foot hot-dip galvanizing facility is set on 35 acres with ample storage and staging space. The kettle, which we believe is the largest in North America, holds 2.58 million pounds of molten zinc. Our internal galvanizer has been named a recognized member of the Green Suppliers Network. The Green Suppliers Network is a collaborative venture among industry participants, the U.S. Environmental Protection Agency, or the EPA, and the Manufacturing Extension Partnership of the U.S. Department of Commerce's National Institute of Standards and Technology, a leading provider of technical assistance to manufacturers. By partnering with the Green Suppliers Network, we have reduced our environmental footprint through lean manufacturing techniques coupled with sound environmental strategies. With 20 metric tons of lifting capacity, we can galvanize large steel fabrications with relative ease. In our Alvarado manufacturing facility, we bring raw materials (primarily steel plate) into the plant where they are run through the burn table, a plasma-cutting device that cuts the rectangular steel plate into a trapezoid. A break press then bends the steel trapezoids into half shells, which are welded and assembled into poles. At each stage, we subject the in-process material to a quality check. The assembled poles are also reviewed by quality control prior to galvanizing or dulling.

We design, engineer and manufacture self-supporting towers and guyed towers used in communications, wind energy and defense applications in Sioux City, Iowa. Our facility there spans approximately 100,000 square feet spread over 23 acres, and includes two manufacturing plants.

We design, engineer and manufacture shelters in Bossier City, Louisiana. Our facility there includes two manufacturing plants totaling 390,000 square feet. Concrete production equipment includes concrete batching operations, mixer trucks, steel casting tables, overhead cranes and various fixtures and templates to support shelter manufacturing. We sample and test concrete in accordance with American Society for Testing and Materials standards. After testing, we deliver the concrete to the casting tables for placement within steel formwork. We manufacture concrete shelters with six panels, which are lifted using overhead cranes, and assembly occurs within 24 hours of casting. Assembled units are moved to a designated area for high pressure washing to remove a thin layer of cement paste to expose the concrete aggregate. In a separate plant, we manufacture lightweight and ultra-lightweight shelters on vertical fixtures. We assemble panels using overhead cranes. Additional equipment within this plant includes welding stations, metal fabrication machinery and various fixtures and templates for lightweight shelter production. Both concrete and lightweight units are moved into a common plant area for completion. Trade work includes carpentry for insulation and finishing, electrical for installation of distribution switchgear and branch circuit devices, and mechanical for installation of HVAC units and hardware. Daily in-process quality control inspections promote high-qulity workmanship and compliance with customer specifications.

Engineering and Technological Capabilities

We apply sophisticated design and engineering systems and processes to develop high-quality products at what we believe to be a lower cost and with shorter production lead times than our competitors. A key component of our industry-leading cost structure in our wireless communications infrastructure segment is our internally developed proprietary end-to-end engineering, design and quoting system, which provides what we believe to be a critical competitive advantage through, among other things, (i) the utilization of hundreds of variables to optimize the production process and decrease costs and lead times, (ii) systemization to reduce inventory and working capital requirements and (iii) a pre-engineering process to limit the need for custom engineering. This enables us to identify the lowest-cost design strategies and realize greater efficiencies by maximizing the use of standardized components. Used in conjunction with AutoCAD 2009, we believe that this software system allows us to provide plot layouts, bills of material, final drawings and permit packages more quickly than our competitors.

Our electric T&D infrastructure segment currently utilizes proprietary software customized for its facility and operations in combination with AutoCAD 2009 and the Power Line Systems family of software to ensure the most cost-effective and optimized structure design for our electric T&D structures. The compatibility of these software systems allows for direct paperless transfer of pole designs, loading cases and structure geometry, allowing for seamless and automated integration of information from initial design through the final computer numerical controlled shop-cutting programs.

We maintain seasoned, in-house engineering teams comprised of a wide range of engineering disciplines and capabilities. Members of our engineering team are licensed in all 50 states, the District of Columbia and Puerto Rico.

Sales and Marketing

We sell our products through a direct in-house domestic sales force and a network of independent sales representatives.

We employ a multi-level selling approach for our wireless communications infrastructure products with our Chief Executive Officer, operating division VPs of Sales and Marketing and in-house sales representatives all working at various customer levels to effectively market our products and services. Our wireless communications infrastructure segment sells its products through a direct in-house sales force. Each member of the sales force is responsible for a particular region and is supported by an inside sales coordinator that handles requests for quotes and correspondence.

We utilize a similar approach to market our electric T&D infrastructure products and services. Our executive management team manages relationships with key customers and is instrumental in winning new business. Our electric T&D infrastructure segment sells its products through a network of independent sales representatives and sales agencies throughout the country. These representatives manage contract details, customer-specific engineering and drafting specifications, and general product sales within a set geographic territory. Each representative manages his or her own accounts from this territory, reporting back to the divisional headquarters in Alvarado, Texas. Given the nature of our electric T&D infrastructure products, in some cases, multi-billion dollar utility transmission projects, utilities and regional transmission organizations perform rigorous audits on potential suppliers. Since entering the electric T&D infrastructure market in 2001, we have gained approval among leading utilities and regional transmission organizations. Our purpose-built, state-of-the-art facility for the production of electric T&D structures enhances our ability to continue to win new customers and successfully pass customer audit processes.

Many state and local regulations governing electrical construction require permits and licenses to be held by individuals who typically have passed an examination or met other requirements.

We are subject to numerous federal, state and local environmental laws and regulations governing our operations, including laws relating to the health, safety and protection of the environment and natural resources and the handling, transportation and disposal of non-hazardous and hazardous substances and wastes, as well as emissions and discharges into the environment, including discharges to air, surface water, groundwater and soil. Some of these laws and regulations require us to

Table of Contents

obtain permits, which contain terms and conditions that impose limitations on our ability to emit and discharge hazardous materials into the environment and periodically may be subject to modification and renewal or revocation by issuing authorities. Failure to comply with these laws, regulations and permits may trigger a variety of administrative, civil and criminal enforcement measures, including the assessment of civil and criminal fines and penalties, the imposition of remedial obligations, assessment of monetary penalties and the issuance of injunctions limiting or preventing some or all of our operations.

We also are subject to laws and regulations that impose liability and cleanup responsibility for releases of hazardous substances into the environment. Under certain of these laws and regulations, such liabilities can be imposed for cleanup of currently and formerly owned, leased or operated properties, or properties to which hazardous substances or wastes were sent by current or former operations at our current or former facilities, regardless of whether we directly caused the contamination or violated any law at the time of discharge or disposal. The presence of contamination from such substances or wastes could interfere with ongoing operations or adversely affect our ability to sell, lease or use our properties as collateral for financing. We could also be held liable under third-party claims for property damage or personal injury and for significant penalties and other damages under such environmental laws and regulations, which could materially and adversely affect our business and results of operations.

In addition, climate change-related legislation has passed the U.S. House of Representatives, which, if enacted by the full Congress, would limit and reduce greenhouse gas emissions from large emitters of greenhouse gasses through a "cap-and-trade" system of allowances and credits and other provisions. Moreover, the EPA has issued a finding that the current and projected concentrations of certain greenhouse gases in the atmosphere, including carbon dioxide, threaten the public health and welfare of current and future generations. While this finding in itself does not impose any requirements on industry or other entities, it authorizes the EPA to regulate directly greenhouse gas emissions through a rule-making process. While we do not have significant greenhouse gas emissions, such current and future legislation and regulations could indirectly negatively affect us, as our suppliers could incur additional compliance costs that could get passed through to us or our customers may move to products made from raw materials that come from less carbon-intensive industries, than, for example, steel, a chief component in our products.

Legal Proceedings

We are subject to various claims and legal proceedings, which arise in the ordinary course of our business. With respect to all such claims and proceedings, we record reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. We do not believe that any of these proceedings, individually or in the aggregate, would be expected to have a material adverse effect on our financial position, results of operations or cash flows.

Board Structure and Composition

Our business and affairs are managed under the direction of our board of directors. Our amended and restated bylaws provide that the authorized size of our board of directors is to be determined from time to time by resolution of the board of directors. Our board of directors is currently comprised of six directors. The authorized number of directors may be changed by resolution duly adopted by at least a majority of our entire board of directors then in office, although no decrease in the authorized number of directors will have the effect of removing an incumbent director from our board of directors until the incumbent director's term of office expires.

James D. Mack serves as our Executive Chairman of the Board of Directors and Peter J. Sandore serves as our President and Chief Executive Officer and as a member of our board of directors. The positions of chairman of the board and chief executive officer are presently separated and have historically been separated at our company. We believe that separating these positions allows our chief executive officer to focus on our day-to-day business, while allowing the chairman of the board to lead the board of directors in its fundamental role of providing advice to, and independent oversight of, management. Our board of directors recognizes the time, effort and energy that the chief executive officer is required to devote to his position in the current business environment, as well as the commitment required of our chairman, particularly as the board of directors' oversight responsibilities continue to grow. Our board of directors believes that having separate positions is the

Table of Contents

appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance.

Director Independence

In April 2010, our board of directors undertook a review of its composition and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our board of directors has determined that Mr. Bradley, representing one of our six current directors, has no relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that is "independent" as defined under Rule 5605(a)(2) of the NASDAQ Listing Rules.

The NASDAQ Listing Rules require that the compensation, nominating and governance and audit committees of a listed company be comprised solely of independent directors. We intend to rely on the transition periods provided by Rule 5615(b) of the NASDAQ Listing Rules and Rule 10A-3 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, which provide for phase-in compliance for companies that are listing on the exchange in connection with their initial public offering. As a result, we plan to have our audit, compensation and nominating and governance committees comprised of a majority of independent directors within ninety days of our listing and comprised solely of independent directors within one year of our listing.

Committees of the Board of Directors

Prior to the completion of the offering, three standing committees of our board of directors will be organized: an audit committee, a compensation committee and a nominating and corporate governance committee.

Audit Committee

The audit committee will assist our board of directors in overseeing and monitoring (i) the quality and integrity of our financial statements, (ii) our independent registered public accounting firm's performance, qualifications and independence, (iii) the review of related party transactions and (iv) the development and performance of our internal audit function.

The members of our audit committee are Mr. Bradley, and , with Mr. Bradley serving as the chairperson of the committee. We believe that Mr. Bradley is an independent director, as defined under the rules of the NASDAQ Stock Market and Rule 10A-3 of the Exchange Act. We believe that each member of our audit committee meets NASDAQ requirements for financial literacy. Mr. Bradley qualifies as an "audit committee financial expert," as defined under applicable SEC rules. The charter of the audit committee will be available on our website.

Compensation Committee

The compensation committee will assist our board of directors in discharging its responsibilities relating to (i) setting our compensation program and compensation of our executive officers and directors, (ii) monitoring our incentive and equity-based compensation plans and (iii) preparing the compensation committee report required to be included in our proxy statement under the rules and regulations of the SEC.

The members of our compensation committee are , and , with serving as the chairperson of the committee. We believe that is an independent director under the applicable rules and regulations of the SEC and the NASDAQ Stock Market. The charter of the compensation committee will be available on our website.

Table of Contents

Nominating and Corporate Governance Committee

The nominating and corporate governance committee will be responsible for developing and recommending to the board of directors criteria for identifying and evaluating candidates for directorships and making recommendations to the board of directors regarding candidates for election or reelection to the board of directors at each annual stockholders' meeting. In addition, the nominating and corporate governance committee will be responsible for overseeing our corporate governance guidelines and reporting and making recommendations to the board of directors concerning corporate governance matters. The nominating and corporate governance committee will also be responsible for making recommendations to the board of directors concerning the structure, composition and function of the board of directors and its committees.

The members of our nominating and corporate governance committee are , and , with serving as the chairperson of the committee. We believe that is an independent director under the applicable rules and regulations of the SEC and the NASDAQ Stock Market. Prior to the completion of the offering, the nominating and corporate governance committee will begin to operate under a written charter that satisfies the applicable standards of the SEC and the NASDAQ Stock Market, which will be available on our website.

Director Compensation

To date for fiscal year 2011, we have paid one of our directors, Mr. Bradley, $31,000 for his service as a director. We reimburse our directors for all reasonable expenses incurred by them to attend board and committee meetings.

Following the completion of the offering, our independent directors will receive quarterly cash compensation in the amount of $6,000 and a $1,000 fee for each meeting of the board attended by such director. Chairs of each of the audit, compensation and nominating and corporate governance committees will receive additional cash compensation of $1,500 quarterly. In addition, each of our independent directors will receive an annual grant of restricted stock in the amount of $20,000 under our proposed 2011 Omnibus Incentive Plan. We will continue to reimburse our directors for all reasonable expenses incurred by them to attend board and committee meetings.

Compensation Committee Interlocks and Insider Participation

None of the members of our compensation committee is or has at any time during the past year been an officer or employee of ours. None of our executive officers currently serves or in the past year has served as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving on our board of directors or compensation committee.

Code of Conduct and Ethics

Prior to the completion of the offering, our board of directors will adopt a code of conduct and ethics that establishes the standards of ethical conduct applicable to all directors, officers and employees of our company. The code will address, among other things, conflicts of interest, compliance with disclosure controls and procedures and internal control over financial reporting, corporate opportunities and confidentiality requirements. The audit committee will be responsible for applying and interpreting our code of conduct and ethics in situations where questions are presented to it.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Overview

In this Compensation Discussion and Analysis, or CD&A, we present our philosophy, programs, and processes related to executive officer compensation, and specifically to compensation of our named executive officers for fiscal 2010, or NEOs, who are listed in the tables below:

Name		Title

Peter J. Sandore*		President, Chief Executive Officer and Director and former Chief Operating Officer
James D. Mack**		Executive Chairman of the Board of Directors and former President and Chief Executive Officer
James M. Tholey		Executive Vice President and Chief Financial Officer
David J. de Poincy***		Formerly President, Electric T&D Infrastructure and formerly President, Sabre Communications Corporation and CellXion, LLC

*: Mr. Sandore was hired as our Chief Operating Officer effective April 27, 2010. He became President and Chief Executive Officer effective February 15, 2011, and was appointed to our board of directors on March 30, 2011.
**: Mr. Mack served as our President and Chief Executive Officer until February 15, 2011, when he became Executive Chairman of the Board of Directors.
***: Mr. de Poincy's employment with us was terminated by us without "cause" on June 7, 2010. See "—Employment Agreements—Severance Agreement and Release and Consulting Agreement with David J. de Poincy" below.

Compensation Philosophy and Objectives

We compensate our NEOs through both short-term cash programs, including annual salary and annual executive incentive plans, and long-term programs, namely the Nonqualified Stock Option Plan and our Incentive Restricted Stock Grant Program. We believe that it is important to have a mix of meaningful long-term and short-term incentive plans for our executive officers to help attract and retain high-performing individuals and drive positive economic performance and enhanced stockholder value. We believe that the pay of our NEOs should be directly linked to performance, thus our compensation programs are designed to reward strong financial performance. We measure the effectiveness of our compensation programs on our success in creating incentives for our NEOs to meet and exceed our financial performance objectives, aligning the interests of our executive officers with those of our stockholders, enhancing our ability to attract and retain executive officers who will provide exceptional levels of service and rewarding team accomplishments while promoting individual accountability.

We seek to maintain the competitiveness of our executive compensation levels with those of our peers and competitors and therefore, make changes to the level of our executive officer compensation from time to time. Adjustments to both overall compensation and the individual components of compensation are based on various factors, including results of compensation studies, published compensation survey data, economic conditions and the effects of inflation, changes in our business operations and changes in the compensation practices of our competitors. We generally target total compensation to be competitive with the total compensation of similar companies whose compensation we review, as further described below. We also take into account the executive officer's individual past and expected performance when making compensation adjustments.

Table of Contents

In connection with becoming a public company, certain aspects of our long-term compensation mix will likely change, primarily in the area of stock options. Currently, stock options are limited to some, but not all, of our executives. Upon completion of the offering, we expect to expand the stock option program, such that additional executives and other key management personnel will be eligible to participate and other equity-based awards may be granted. Expanding our compensation policies is intended to enable us to attract and retain top quality management as well as to motivate management to maximize performance while building stockholder value.

Management's Role in the Compensation Setting Process

Compensation for our NEOs is evaluated and determined by our board of directors. Most key compensation decisions are made prior to or at fiscal year-end as we review prior year financial performance and performance of executive officers and set compensation targets and objectives for the coming year.

Our Chief Executive Officer assists the board of directors in its oversight and determination of compensation. The Chief Executive Officer's role includes assisting the board of directors with evaluating employee performance, assisting with establishing individual and company-wide performance targets and objectives, recommending salary levels, stock options and other equity incentive grants, providing financial data on company performance, and providing calculations and reports on achievement of performance objectives, other than with respect to the performance and compensation of the Chief Executive Officer. Our Chief Financial Officer works with the Chief Executive Officer in making recommendations regarding our overall compensation policies. The board of directors (excluding the Chief Executive Officer and the Executive Chairman of the Board of Directors) makes all decisions regarding the compensation of our NEOs without the permission or presence of the Chief Executive Officer, the Executive Chairman of the Board of Directors or any other member of management. The Chief Executive Officer also has the discretion to grant certain equity and incentive payments under our EICP, as further described below. Currently outstanding equity incentive awards were determined by our Executive Chairman of the Board of Directors, other than grants to our Executive Chairman of the Board of Directors, which were determined by our board of directors. Our board of directors or the compensation committee is expected to grant and administer future equity awards.

We do not engage in formal compensation benchmarking; however, we have in the past reviewed compensation surveys and engaged compensation consultants on an ad hoc basis in order to ensure that we provide competitive compensation, as described below. The Chief Executive Officer or the board of directors may authorize management to engage compensation consultants and other advisers as they deem appropriate. Prior to the offering and becoming a public company, management engaged Growth Management Strategies, LLC to review our current compensation plans and philosophies and compare them to those of other firms, competitors and industries. Industries included in the review were metal fabrication and production, telecommunications, utility transmission, electric power generation and others. The review covered publicly available compensation data, including that of recent newly public companies, published reports by the Economic Research Institute and Towers Watson & Co., and Durable Goods Manufacturing survey data. However, compensation levels for our NEOs were not based upon, or "benchmarked" against, a particular level or percentile of the companies or surveys that were reviewed, nor have we tracked a given set of industry competitors over time (or determined which companies are included in any specific data set). While an understanding of the median compensation practices of industry competitors provides a basis for determining whether our compensation practices are reasonable and/or competitive, it has served as only one of several factors that we have considered in setting compensation levels for individual employees. The board of directors and its compensation committee, which will be established prior to the completion of the offering, expect to use compensation studies in connection with reviewing and establishing our compensation practices. The compensation committee will expand its role in reviewing and approving

Table of Contents

executive compensation and determining how to provide incentive compensation opportunities that are competitive with our peer companies.

It is anticipated that the compensation committee will assist our board of directors in discharging its responsibilities relating to (i) setting our compensation program and compensation of our executive officers and directors, (ii) monitoring our incentive and equity-based compensation plans, and (iii) preparing the compensation committee report required to be included in our proxy statement under the rules and regulations of the SEC.

The board of directors and Chief Executive Officer meet as often as required during the year in furtherance of their respective duties, including a review of all of our annual incentive plans and compensation of our NEOs.

Elements of Executive Compensation

For NEOs, the key components of total compensation include:

•: base salary;
•: annual executive incentive compensation program, or EICP;
•: long-term incentive compensation in the form of awards of stock options and restricted stock; and
•: 401(k) defined contribution plan and other benefits and perquisites.

Each component of our compensation program has an important role in creating compensation payouts that motivate and reward strong performance and in retaining the NEOs who deliver such performance.

Base Salary

Base salary is a critical component of our executive officers' compensation because it provides executive officers with a base level of monthly income that is consistent with industry practices. In determining base salaries, the board of directors considers the executive officers' qualifications and experience, responsibilities, past performance and goals and objectives. Base salaries for the new fiscal year are established for our executive officers prior to fiscal year-end. Accordingly, except with respect to Mr. Sandore, each executive officer's base salary for fiscal 2010 was originally set prior to April 30, 2009. Mr. Sandore's base salary was set in April 2010 in connection with the hiring of Mr. Sandore as our Chief Operating Officer and the termination of the Independent Contractor Agreement (the "Consulting Agreement") entered into on May 1, 2009, between us and Business Resource Consulting, LLC ("BRC"), an entity controlled by Mr. Sandore.

The base salaries of the NEOs were initially set by their respective employment agreements and were initially determined by evaluating the responsibilities of the position, the experience of the individual and, based on the salaries of similarly situated employees of our peer industries listed above, the salaries for comparable positions in the competitive marketplace. Each of these salaries is subject to periodic review and adjustment by our board of directors. Base salaries may be increased to realign salaries with market levels after taking into account individual responsibilities, performance and experience. Based on publicly available information, the board of directors believes that the base salaries established for NEOs are generally competitive and comparable to those paid by similarly situated companies in our industry. We focus on compensation data that we are able to obtain from competitor industries with similar revenue levels as ours. A number of our direct competitors currently have significantly greater revenues and compensation structures in those companies are generally higher. In determining salary adjustments for executive officers, where appropriate, the board of directors also considers non-financial performance measures such as improvements in product quality, manufacturing efficiency gains and the enhancement of relations with our customers and employees.

Table of Contents

The board of directors exercises discretion in increasing the base salaries of our executive officers from the prior fiscal year within the guidelines discussed above.

The following table sets forth the fiscal 2010 base salaries for each of our NEOs:

Name	Fiscal 2010 Base Salary

James D. Mack*	$	350,000
James M. Tholey	$	275,000
Peter J. Sandore**	$	325,000
David J. de Poincy***	$	250,000

*: Mr. Mack served as President and Chief Executive Officer until February 15, 2011, when he was appointed as Executive Chairman of the Board of Directors.
**: Effective April 27, 2010, in connection with the hiring of Mr. Sandore as our Chief Operating Officer. Mr. Sandore became our President and Chief Executive Officer on February 15, 2011.
***: Effective June 7, 2010, Mr. de Poincy's employment with us was terminated by us without "cause."

As noted above, we do not provide standard annual raises in the base salaries of our executive officers. Instead, our board of directors periodically reviews the base salaries of our executive officers based on the individual and company-wide performance criteria described above. Due to a substantial increase in the complexity of our business, the expansion of our workforce (including a significant increase in the number of individuals reporting directly to the NEOs) and an increase in activity relating to the offering, for fiscal 2011, the base salaries for our NEOs are anticipated to increase as follows effective as of the completion of the offering:

Name	2011 Base Salary Increase

James D. Mack	$	50,000
James M. Tholey	$	75,000
Peter J. Sandore	$	150,000

Incentive Compensation

Our NEOs, as well as other key management employees, participate in the Executive Incentive Compensation Program, or EICP, which provides an opportunity to earn cash bonuses, equity and stock options, exit bonuses and bonuses for the acquisition of other entities upon achievement of targets approved by the Chief Executive Officer and board of directors (such as specifically defined revenue and adjusted EBITDA objectives). These performance objectives are designed to reward both short-term and long-term performance and align management compensation with long-term stockholder value and overall company objectives. Short- and long-term incentive compensation also provides a supplement to the executives' annual base salaries. Our goal is to link the company and executive performance to provide total annual compensation that is competitive with that of executives in other comparable industries. The EICP structure was established several years ago to provide incentive to key executives to achieve the significant growth, operating efficiencies and profitability goals of the company. The goals set forth under the program at that time, as well as the calculations and payouts of earned bonuses, have remained the same. The structure of the program also includes established limits to bonus awards to eliminate potential adverse effects to the financial well being of the company. The Chief Executive Officer, in consultation with the board of directors (or the board of directors alone, in the case of awards applicable to the Chief Executive Officer), has the discretion to provide additional bonus amounts to individuals deemed to have made significant contributions to the organization. The EICP sets out financial performance goals for overall company growth for corporate executives and similar divisional growth metrics for participants with leadership roles in our various operating units.

Table of Contents

Corporate executive metrics for each plan year are comprised of three components: revenue, adjusted EBITDA and adjusted EBITDA margin as a percentage of revenue. These components are weighted 25%, 50% and 25%, respectively. Annually, we have allowed for up to $1,600,000 for the payout of the above-named performance targets.

Upon the achievement of maximum performance goals in respect of our fiscal year ended April 30, 2010, our Chief Executive Officer would be eligible to earn a bonus of up to $350,000, or 100% of his base salary, our Chief Financial Officer would be eligible to earn up to $151,250, or 55% of his base salary, and Mr. de Poincy would be eligible to earn up to $137,500, or 55% of his base salary. All other participants in the program are typically eligible to earn up to 45% of their base salaries. If target performance goals were achieved, our Chief Executive Officer would be eligible to earn a bonus of up to 50% of his base salary and Messrs. Tholey and de Poincy would be eligible to earn up to 35% of their base salaries. If minimum performance goals were achieved, our Chief Executive Officer would be eligible to receive a bonus of up to 25% of his base salary and Messrs. Tholey and de Poincy would be eligible to earn up to 17.5% of their base salaries. Upon achievement of performance in between the minimum, target and maximum goals, bonus amounts would be based on straight-line interpolation between the foregoing amounts. No annual bonus would be payable to the foregoing individuals unless minimum performance targets are met. As Mr. Sandore became our Chief Operating Officer on April 27, 2010, he was not eligible to earn a bonus with respect to our fiscal year ended April 30, 2010.

The following table sets forth the performance goals applicable to our fiscal year ended April 30, 2010, which were approved by our board of directors as of June 10, 2009.

Threshold Level

Financial Goal	Minimum			Target			Maximum

Revenue	$	287,000,000		$	297,000,000		$	310,073,892		25	%
Adjusted EBITDA ($)	$	34,500,000		$	37,000,000		$	40,875,886		50	%
Adjusted EBITDA (%)		11.80	%		12.15	%		12.30	%	25	%

Fiscal 2010 results for all measurement criteria are below minimum threshold levels. Accordingly, performance-based annual bonuses were not paid to our NEOs in respect of fiscal 2010.

For our fiscal year ending April 30, 2011, the target bonus amounts that may be earned under the EICP in respect of maximum, target and threshold revenue and adjusted EBITDA performance for our NEOs have been revised as follows: for Mr. Mack, they are 80%, % and % of his base salary, respectively; for Mr. Tholey, they are 60%, % and % of his base salary, respectively; and for Mr. Sandore, they are 70%, 40% and % of his base salary, respectively.

The EICP also makes available to participants, excluding the Chief Executive Officer, up to $500,000 in equity grants, in the aggregate, which are granted under our Nonqualified Stock Option Plan and restricted stock awards. The Chief Executive Officer, at his discretion, can make outright grants of stock in an equity pool or make stock available for purchase. At the creation of the program, an option pool of 5% of our fully diluted shares was made available with 19,000 options awarded by the board of directors to Mr. Mack (formerly our President and Chief Executive Officer). The remaining options were granted to other executives at the sole discretion of the Executive Chairman of the Board of Directors.

In addition, if our annual adjusted EBITDA exceeds the outstanding target level as defined annually by the board of directors, an additional annual cash rewards pool will be established at 25% per dollar of the amount by which EBITDA exceeds the outstanding target level up to an additional pool of $1,000,000. If the target level is significantly exceeded, at the discretion of our majority stockholder, Corinthian Capital, the additional annual cash rewards pool may be increased above the maximum $1,000,000. The Chief Executive Officer will determine how to allocate the annual cash rewards pool, other than with respect to his own award, which is set by the board of directors.

Table of Contents

The Chief Executive Officer reviews and approves all potential payouts under the EICP, except his own, which is approved by our board of directors, and he has the authority to modify or suspend payment under the program at any time. This program is unfunded and all payouts are paid to participants out of currently available operating cash.

Transaction Bonuses. The EICP contains an exit bonus pool, which may be made available by the selling stockholders upon the sale of the company or certain other liquidity events, including the offering. Certain key employees, including our NEOs, are eligible to participate in the exit bonus pool. The size of the exit bonus pool will depend upon the achievement of a specific level of cash on cash return to the limited partners of an affiliate of our majority stockholder, Corinthian Capital, as determined at the sole discretion of the board of directors. In consultation with the board of directors, the Executive Chairman of the Board of Directors shall make the final determination of how to allocate the exit bonus pool among eligible participants. The cash on cash return is defined as the yield determined by dividing the total cash return by the total cash investment.

Mr. Tholey is entitled to participate in the exit bonus portion of the EICP pursuant to his employment arrangement with us, and is eligible for an exit bonus of $350,000 or more, if the cash on cash return, as calculated by our majority stockholder, is in excess of six times, subject to approval by the Executive Chairman of the Board of Directors. The maximum aggregate amount of exit bonuses payable under the EICP to all members of our management team as a result of the completion of the offering and any subsequent offerings or other exit transactions is $5.5 million.

Our NEOs are expected to become entitled to exit bonuses of approximately $ , for Mr. Mack, $ , for Mr. Tholey, and $ , for Mr. Sandore, each as a result of the completion of the offering, subject to the return of to the limited partners of our majority stockholder, Corinthian Capital. The exit bonus payments will be made by our stockholders selling in the offering on a pro rata basis in accordance with the number of shares sold by such stockholders. In addition, the amount of any exit bonus payments will be pro rated to reflect the percentage of our shares sold in the offering.

In anticipation of potential acquisitions of other companies, the EICP also established a deal bonus for key employees, including our NEOs, who play a critical role in any such acquisition. The deal bonus is intended to reward key employees and executives who will be required to perform additional work and effort in order to secure and execute transactions and successfully integrate any acquired business.

Long-Term Incentive Compensation

We believe that long-term performance is achieved through an ownership culture that rewards and encourages long-term performance by our NEOs through the use of stock-based awards. We believe that equity compensation is an effective means of aligning the long-term interests of our employees, including our executive officers, with our stockholders. We strive to increase stockholder value through the utilization of our Nonqualified Stock Option Plan and grants of restricted stock, which are determined by the Chief Executive Officer (other than grants to the Chief Executive Officer, which are determined by the board of directors).

In determining the total size of equity awards, the Chief Executive Officer considered various factors such as the outstanding number of options and shares of restricted stock, the amount of additional shares available for issuance under the Nonqualified Stock Option Plan, the level of responsibility of the proposed recipient and his or her performance and the percent of the outstanding shares of our common stock represented by outstanding options and shares of restricted stock. The purpose of these grants is to encourage stock ownership by key management, to provide incentive for executives to expand and improve our profits, to align the interests of our employees with those of our stockholders and to attract and retain key personnel.

Table of Contents

Grants of stock options and restricted stock are administered by the Chief Executive Officer, who makes all decisions with respect to participation in and extent of participation in the Nonqualified Stock Option Plan and with respect to grants of restricted stock. In connection with becoming a public company, management of the Nonqualified Stock Option Plan will likely transition to that of the newly formed compensation committee, and the plan may be changed in part, in whole or replaced outright at the discretion of the compensation committee or the board of directors. Unless the Nonqualified Stock Option Plan is terminated earlier, the plan will terminate on May 10, 2016.

Nonqualified Stock Option Plan

The maximum number of shares of stock that may be optioned under the Nonqualified Stock Option Plan, which was established in May 2006, is 91,304 shares. All awards under the plan are granted by the Chief Executive Officer, except that awards granted under the plan to the Chief Executive Officer are determined by our board of directors. Grants under the Nonqualified Stock Option Plan are made at the discretion of the Chief Executive Officer based on past and expected future performance and are intended, together with other base and incentive compensation provided to our employees, to be competitive with such remuneration provided by our peer group of industries as discussed above. All stock options are granted with an exercise price equal to the fair market value of our stock on the date of grant. Stock options vest over a four-year period at 20% at the date of the grant and 20% per year on each of the first four anniversaries of the grant date, subject to the grantee's continued employment through each applicable vesting date. All options granted expire 10 years after the date of grant. Upon the occurrence of a change in control (defined as any sale, lease, exchange or other transfer of all or substantially all of our assets, certain consolidations, mergers or plans of share exchange involving us and certain liquidations or dissolutions of us), all outstanding stock options shall become fully exercisable. The completion of the offering will not constitute a change in control for purposes of the Nonqualified Stock Option Plan.

If an option holder ceases to be employed by us, his or her non-vested stock options shall terminate immediately; provided that if an option holder's cessation of employment with us is due to his or her retirement with our consent or the consent of any of our subsidiaries, the option holder may, at any time within three months after such cessation of employment, exercise any vested stock options to the extent that he or she was entitled to exercise them on the date of cessation of employment, but in no event shall any stock option be exercisable more than 10 years from the date it was granted. The Chief Executive Officer may cancel a stock option during the three-month period previously referred to if the option holder engages in employment or activities contrary, in the opinion of the board of directors, to our best interests or the best interests of any of our subsidiaries. The Chief Executive Officer shall determine in each case whether a termination of employment shall be considered a retirement with our consent or the consent of a subsidiary, and, subject to applicable law, whether a leave of absence shall constitute a termination of employment. If an option holder dies while employed by us or any of our subsidiaries without having fully exercised vested stock options, the executors or administrators, or legatees or heirs, of the option holder's estate shall have the right to exercise the stock options to the extent that such deceased option holder was entitled to exercise the stock options on the date of his or her death.

If an option holder ceases to be employed by us for any reason or no reason, with or without cause, including death or disability, we shall have an irrevocable, exclusive option for a period of 120 days from the date of termination of employment to purchase any shares of common stock acquired by the option holder upon exercise of the stock options. We may exercise this repurchase option by delivering to the option holder (or to his or her executors or administrators, if applicable) a written notice of exercise and a check for the original purchase price paid by the option holder; provided that in the case of death or retirement with our consent, the price shall be the fair market value of such shares as determined by our board of directors. Such repurchase rights terminate upon

the completion by us of a public offering of our common stock registered under the Securities Act, including the offering.

2011 Omnibus Incentive Plan

Prior to the completion of the offering, we intend to adopt, subject to stockholder approval, the Sabre Industries, Inc. 2011 Omnibus Incentive Plan, which will be an amendment and restatement of the Nonqualified Stock Option Plan and will enable us to offer certain key employees, consultants and non-employee directors equity-based awards. The purpose of the plan is to enhance our profitability and value for the benefit of stockholders by enabling us to offer equity-based incentives in order to attract, retain and reward such individuals, while strengthening the mutuality of interests between those individuals and our stockholders.

Our compensation committee will administer the plan and select the individuals who are eligible to participate in the plan. The plan permits us to grant stock options (non-qualified and incentive stock options), stock appreciation rights, restricted stock, performance shares and other stock-based awards (including, without limitation, restricted stock units and deferred stock units), which in each case may be subject to the attainment of performance goals, to the extent determined by the compensation committee, and grants of performance-based incentive awards payable in cash, to certain key employees, consultants and non-employee directors, as determined by the compensation committee. In addition, the compensation committee may permit non-employee directors to defer all or a portion of their cash compensation in the form of other stock-based awards granted under the plan, subject to the terms and conditions of any deferred compensation arrangement established by us.

Up to shares of our common stock may be issued under the plan (subject to adjustment to reflect certain transactions and events specified in the plan). If any award granted under the plan expires, terminates or is canceled without having been exercised in full, the number of shares underlying such unexercised award will again become available for awards under the plan.

The compensation committee will have discretion to delegate all or a portion of its authority under the plan, and the compensation committee will also determine the terms and conditions of the awards at the time of grant in accordance with the terms of the plan.

The plan is intended to constitute a plan described in Treasury Regulation Section 1.162-27(f)(1), pursuant to which the deduction limits under Section 162(m) of the Internal Revenue Code do not apply during the applicable reliance period. In general, the reliance period ends upon the earliest of: (i) the expiration of the plan (i.e., 10 years after the date the plan is approved by stockholders); (ii) the material modification of the plan; (iii) the issuance of all available stock under the plan; or (iv) the first stockholder meeting at which directors are to be elected that occurs after December 31, 2013. The compensation committee intends to utilize performance-based compensation programs that meet the deductibility requirements under Section 162(m). However, the compensation committee may approve compensation that may not be deductible if the Committee determines that such compensation is in our best interests, which may include for example, the payment of certain non-deductible compensation necessary in order to attract and retain individuals with superior talent. While it is expected that the compensation committee will administer grants under the Omnibus Incentive Plan for our NEOs, grants will be made and administered by our board of directors until our compensation committee is in place.

Incentive Restricted Stock Grants

The maximum number of shares of stock available for the grant of restricted stock is shares pursuant to our incentive restricted stock grant program, which was established in May 2006. All shares have been granted by the former Chief Executive Officer (except for grants to the former Chief Executive Officer, which are determined by the board of directors). Our board of directors or the compensation committee is expected to grant and administer future equity awards. Awards of restricted stock are vested on the date of grant, subject to customary restrictions on the transferability thereof.

Table of Contents

Upon termination for cause as defined by the applicable grant agreements, all restricted shares held by the participant will be forfeited. Upon voluntary termination of a participant's employment, we shall have the right to elect to purchase the participant's shares at a price of 50% of the fair market value of such shares as determined by the board of directors. Payment due to the participant for the sale of the shares to us will be held in escrow from one year to eighteen months. If the participant has not been employed, either directly or indirectly, by a business in competition with us for up to eighteen months following the voluntary termination, the escrowed proceeds plus interest shall be delivered to the participant. If the participant is subsequently employed, either directly or indirectly, by a business in competition with us within eighteen months from the date of termination, the participant's shares shall be forfeited to us. Grants of restricted stock are intended, together with other base and incentive compensation provided to our employees, to be competitive with such remuneration provided by companies in our peer industry group as discussed above.

11,000 shares of restricted stock were granted to Mr. Tholey on his date of hire, with one-third of such shares vesting on his date of hire, January 28, 2008, and an additional one-third of such shares vesting on each January 28 thereafter, so that all such shares vested as of January 28, 2010. All other restrictions on the restricted shares issued to Mr. Tholey are similar to those discussed above.

The following is a summary of the non-qualified stock options awarded to our NEOs and currently outstanding:

Name		Number of Stock Options

James D. Mack			15,200
James M. Tholey			—
Peter J. Sandore			—
David J. de Poincy			—

Prior to the completion of the offering, we intend to grant to Mr. Tholey, subject to stockholder approval of the 2011 Omnibus Incentive Plan and to the completion of the offering, 5,000 stock options and 5,000 shares of restricted stock. Half of such options and restricted shares will vest on the initial public offering date and the balance will vest on January 1, 2012, subject to Mr. Tholey remaining employed by the Company through such dates and subject to the terms of the plan. The exercise price of the stock options granted to Mr. Tholey will be the same as the initial public offering price.

On and after the effective date of the 2011 Omnibus Incentive Plan (discussed above), we expect that any additional shares of restricted stock will be granted under the Omnibus Incentive Plan. However, previously granted shares of restricted stock will continue to remain outstanding in accordance with the terms of the applicable grant agreement and the plan.

Perquisites and Other Compensation

Each NEO is also eligible to participate in all other benefit plans and programs that are or in the future may be available to our other executive employees, including any health insurance or health care plan, disability insurance, 401(k) supplemental retirement plan, vacation and sick leave plan, and other similar plans. In addition, each NEO is eligible for certain other benefits, including life insurance of at least one times their base salary up to $250,000 of group term life insurance coverage, reimbursement of business and entertainment expenses and use of a company car and credit card. The board of directors may revise, amend or add to the officer's executive benefits and perquisites as it deems advisable. We believe that these benefits and perquisites are consistent with those provided to senior executives at companies in our industry. These benefits are included in the Summary Compensation Table in the "All Other Compensation" column.

Table of Contents

Exercise of Discretion in Executive Compensation

The board of directors has complete discretion to withhold payment pursuant to any of our incentive compensation plans regardless of whether we or our NEOs have successfully met the goals set under these plans. Likewise, the board of directors has the authority to grant payment under any of the plans despite the non-attainment by us or our NEOs of the pre-established goals. For 2010, the board of directors has not exercised such discretion in the payment or non-payment of awards to our NEOs.

Severance and Change in Control Arrangements

All of our NEOs are parties to non-compete agreements entered into at the time of their initial hire by us. Messrs. Mack and Tholey are also party to severance agreements entered into at the time of their initial hire by us. Under the agreements, Messrs. Mack and Tholey and other key individuals are eligible for severance benefits consisting of base salary continuation, ranging from 12 to 24 months, respectively, and paid COBRA coverage.

Additionally, in the event of a change in control (as defined in the stock option plan), all of the unvested options held by the executive would become fully vested.

Please refer to the discussion below under "—Potential Payments upon Termination or Change in Control" for a more detailed discussion of our severance and change in control agreements.

Stock Ownership Guidelines

The board of directors has not implemented stock ownership guidelines. The board of directors has chosen not to require stock ownership because of the limited market for our common stock. The board of directors will continue to periodically review best practices and re-evaluate our position with respect to stock ownership guidelines.

Impact of Tax and Accounting Requirements on our Executive Compensation Decisions

We account for stock-based awards in accordance with the requirements of accounting for share-based payments. Under Financial Accounting Standards Board Accounting Standards Codification Topic 718, grants of options and restricted stock result in an accounting charge equal to the fair market value of the award over the vesting period as determined on the grant date. For restricted stock, the charge is equal to the fair value of the stock on the date of grant multiplied by the number of shares granted. For options, the charge is equal to the Black-Scholes value on the date of grant multiplied by the number of option shares granted. This expense is recognized over the requisite service or vesting period of the applicable equity awards. Our board of directors considers the accounting and tax implications of its compensation decisions as one factor among many in achieving its executive compensation objectives.

Section 162(m) of the Internal Revenue Code limits the deductibility of executive compensation paid by a publicly held company to $1,000,000 per individual NEO (other than the Chief Financial Officer) per year. This limitation generally does not apply to performance-based compensation under a plan that is approved by the stockholders of a company that also meets certain other technical requirements. The EICP, the Nonqualified Stock Option Plan and Incentive Restricted Stock Grant Plan will be approved by stockholders prior to the completion of the offering and therefore awards under such plans will be exempt from Section 162(m) during the reliance period under applicable regulations. With respect to each plan, this reliance period will end at the 2013 Annual Meeting of Stockholders, provided that they are not previously materially amended.

Policy Regarding Restatements

We do not currently have a formal policy requiring a fixed course of action with respect to compensation adjustments following later restatements of financial results. Under those circumstances,

Table of Contents

our board of directors would evaluate whether compensation adjustments were appropriate based on the facts and circumstances surrounding the restatement.

Conclusion

We have designed and administered our compensation program in a manner that emphasizes the retention of key executive officers and rewards them appropriately for positive results. We monitor the program in recognition of the dynamic marketplace in which we compete for talent and will continue to emphasize pay-for-performance and equity-based incentive plans that reward our NEOs for results consistent with the interests of our stockholders.

Employment Agreements

Each of Mr. Mack and Mr. Tholey has an employment agreement with us, and we were party to the Consulting Agreement with BRC, an entity controlled by Mr. Sandore. The terms of these agreements include the following:

James D. Mack—We are party to an employment agreement with Mr. Mack entered into on May 9, 2006. The agreement had an initial term of three years, after which it remains effective for successive one-year periods until we give or are provided by Mr. Mack with 30 days, notice of the termination prior to each successive renewal. The agreement provides for an initial base salary of $350,000 per year, which is subject to annual increase at the discretion of the board of directors. In addition, pursuant to his employment agreement, Mr. Mack is eligible to receive an annual performance bonus of up to 100% of his base salary based on objectives determined by the board of directors, and is eligible to participate in the Nonqualified Stock Option Plan. The employment agreement entitles Mr. Mack to participate in the benefit programs generally provided by us to our executive employees.

In the event that Mr. Mack's employment terminates as a result of a "constructive termination" (as defined in his employment agreement) or his termination of employment without "cause" (as defined in his employment agreement), Mr. Mack will be entitled following his termination to receive two years of base salary continuation payments and, subject to his election of COBRA continuation benefits and payment of the employee premium then in effect, two years of continued participation in our health insurance plans. The foregoing severance payments and benefits are subject to Mr. Mack's execution of a release of any claims against us, and to his continued compliance with his restrictive covenant obligations described below.

Mr. Mack is subject to restrictive covenants, including non-compete and non-solicitation provisions, while he is employed by us and for specified periods of time thereafter. Pursuant to such provisions in his employment agreement, Mr. Mack shall not engage in any activity in competition with our then-current business while employed by us or at any time during the two-year period following his cessation of employment by us for any reason. In addition, during his employment and such two-year period thereafter, Mr. Mack is prohibited from soliciting business from our customers or clients, and from soliciting any of our employees for employment.

James M. Tholey—We are party to an employment letter agreement with Mr. Tholey entered into on December 26, 2007, as amended on April 30, 2008 and November 7, 2008.

Please refer to "Certain Relationships and Related-Party Transactions—Independent Contractor Agreement" for a summary of the Consulting Agreement.

Table of Contents

Employment Agreements To Be Entered Into In Connection With the Offering. In connection with the offering, we intend to enter into new employment agreements with Messrs. Sandore, Mack and Tholey that, in the case of Messrs. Mack and Tholey, will supersede their employment agreements described above upon the completion of the offering. The employment agreements with Messrs. Sandore, Mack and Tholey are expected to be in substantially the same form as Mr. Mack's current employment agreement, and are expected to provide for a three-year term of employment, after which the employment agreements will remain effective for successive one-year periods until we give or are provided by the executive with 60 days' notice of termination prior to each successive renewal.

The agreements will provide for initial base salaries of $475,000, $400,000 and $350,000 per year for Messrs. Sandore, Mack and Tholey, respectively, subject to an annual increase at the discretion of the board of directors. In addition, the employment agreements are expected to provide for annual performance bonuses of up to 90%, 90% and 65% of the base salaries of Messrs. Sandore, Mack and Tholey, respectively, based on objectives determined by the board of directors and eligibility to participate in the benefit programs generally provided by us to our executive employees.

The new employment agreements are also expected to provide for the grant to Messrs. Sandore, Mack and Tholey of , and options to purchase shares of our common stock and to Mr. Sandore of restricted shares of our common stock pursuant to the terms of the 2011 Omnibus Incentive Plan.

In each case, under the expected terms of the new employment agreements, if the executive's employment is terminated by us prior to the end of the agreement term without "cause" (as defined in the employment agreements) or by the executive for "good reason" (as defined in the employment agreements), the executive will be entitled to the following severance payments and benefits, subject to the execution and non-revocation of a release of claims against us: one year of continued base salary payments and one year of continued participation in our health insurance plans, subject to the executive's election of COBRA continuation benefits and continued payment of applicable employee premiums. The foregoing health insurance benefits will end on the earlier of the first anniversary of the executive's date of termination, or earlier participation in health insurance plan(s) provided by another employer. The continued provision of the foregoing post-termination severance and benefits will also be subject to each executive's continued compliance with the restrictive covenant obligations described below.

Severance Agreement and Release and Consulting Agreement with David J. de Poincy. Mr. de Poincy's employment with us was terminated by us without "cause" on June 7, 2010. We entered into a severance agreement and release with Mr. de Poincy, pursuant to which he has released any claims against us. In addition, we entered into a consulting agreement with Mr. de Poincy with a six-month term beginning on June 7, 2010. Pursuant to the consulting agreement, Mr. de Poincy provided assistance to us with respect to our ongoing operations to the extent requested by us in our discretion, and was paid a monthly consulting fee of $16,500 during the term of the agreement. Mr. de Poincy agreed, pursuant to the consulting agreement and during its term, not to compete with us or solicit our employees or customers and not to disclose any confidential information relating to us.

Potential Payments Upon Termination or Change in Control

We have entered into employment agreements and change of control employment agreements with certain of our NEOs. Our agreements with Messrs. Mack and Tholey provide for severance benefits following a termination of employment, as well as provide employment benefits in connection with a change of control. See the table at the end of this section for the amount of compensation and benefits that would have become payable under existing plans and contractual arrangements assuming a termination of employment and/or change of control had occurred on April 30, 2010 based on the estimated fair market value of our common stock on that date of $8.09, given the NEO's compensation and service levels as of such date. Due to the number of factors that affect the nature and amount of any potential payments or benefits, any actual payments and benefits may be different. Unless otherwise noted specifically below, a change of control will not be triggered as a result of the offering.

With regard to Mr. Mack, severance benefits will be provided for as follows. Upon termination for cause, we will have no obligation related to severance compensation. Termination for cause as defined by Mr. Mack's employment agreement includes: continued failure to perform his duties, willful misconduct or gross negligence that damages us, his breach of the employment agreement, his conviction for a felony and his indictment for embezzlement. Upon his termination of employment without cause or as a result of a constructive termination, Mr. Mack will be entitled to base salary continuation and group health premiums for two years following the date of his termination, subject to Mr. Mack's execution of a release of any claims against us. "Constructive termination" is defined in his employment agreement as a material adverse change in Mr. Mack's compensation or title.

With regard to Mr. Tholey, severance benefits will be provided as follows. Upon termination without cause or change of control that results in relocation of responsibilities, Mr. Tholey will be entitled to base salary continuation and group health premiums for one year following the termination date.

In addition, Mr. Tholey is entitled to participate in the exit bonus portion of the EICP pursuant to his arrangements with us as described herein. In order to receive an exit bonus payment, he must remain employed through the date on which the relevant cash on cash return was realized.

The table below reflect amounts that would become payable to our NEOs under existing plans and employment agreements and arrangements, based on the assumptions set forth above. The amounts shown assume that such termination of employment or change of control was effective as of April 30, 2010, and that the limited partners of an affiliate of our majority stockholder received a cash on cash return on their investment in us of at least six times, as of April 30, 2010. The actual amounts that would be paid upon an NEO's termination of employment or change of control can be determined only at the time of any such event. The actual value that would be recognized by an NEO with respect to his or her stock options can only be determined at the time of exercise and could be affected by changes to the fair market value of our common stock following termination of employment. Due to the number of factors that affect the nature and amount of any benefits provided upon the events discussed below, any actual amounts paid or distributed may be higher or lower than reported below. In addition, in connection with any actual termination of employment or change in control transaction,

we may determine to enter into one or more agreements or to establish arrangements providing additional benefits or amounts, or altering the terms of benefits described below.

CERTAIN RELATIONSHIPS AND RELATED-PARTY TRANSACTIONS

Related-Party Transactions

Other than employment agreements, compensation plans and other arrangements that are described under "Executive Compensation," the transactions described under "Principal and Selling Stockholders—Acquisition of Our Securities by the Selling Stockholders" and the transactions described below, since January 1, 2006, there has not been, and there is not currently proposed, any transaction or series of similar transactions to which we were or will be a party in which the amount involved exceeded or will exceed $120,000 and in which any of our directors, executive officers, holders of more than 5% of any class of our voting securities or any member of the immediate family of the foregoing persons had or will have a direct or indirect material interest. We believe that we have executed all of the transactions set forth below on terms no less favorable to us than we could have obtained from unaffiliated third parties.

Stockholders Agreement

We entered into a stockholders agreement, dated September 12, 2007, with Corinthian Capital and certain other stockholders. The stockholders agreement will terminate automatically upon the completion of the offering. The stockholders agreement defines our relationship with certain stockholders and the rights and obligations of these stockholders and automatically terminates upon the occurrence of any of the following events: (i) the cessation of our business; (ii) our liquidation, dissolution or winding up; (iii) the sale of us; (iv) whenever one holder owns all of our outstanding capital stock and no options are outstanding; (v) the written consent of us, Corinthian Capital and the holders of at least a majority of all our capital stock and securities convertible or exchangeable into our capital stock; or (vi) the time that a registration statement with respect to an underwritten public offering of our common stock is declared effective by the SEC.

The stockholder parties to the stockholders agreement have preemptive rights with respect to the issuance of certain additional securities (not including the shares of common stock being offered by us in this offering), are subject to transfer restrictions of shares of our capital stock held by such parties and have certain co-sale rights. In addition, subject to certain rights and conditions, we must furnish annual and monthly financial statements to each stockholder party as soon as available after the end of the applicable reporting period.

Subject to certain rights and conditions, if Corinthian Capital approves a sale of us to an independent third party on an arm's-length basis, each stockholder party is required to participate in the sale and consent to the sale, waive any appraisal rights and take all actions necessary to complete the sale. In addition, subject to certain rights and conditions, under the stockholders agreement, all stockholder parties must vote their shares to elect or remove any directors as designated by Corinthian Capital, ZM Private Equity Fund I, L.P. and Mr. Mack. Subject to certain rights and conditions, the prior written consent of certain stockholder parties are also required to approve certain corporate matters.

The stockholders agreement provides that we will pay to Corinthian Capital fees equal to 5% (or such lesser amount determined by Corinthian Capital) of (i) the gross total transaction value with respect to the acquisition of all the equity or substantially all the assets of any person not affiliated with us, (ii) the gross total transaction value with respect to a sale of all of the capital stock of us or our subsidiary, Sabre Communications Holdings, Inc., or a sale of substantially all of our assets and (iii) the proceeds of any dividend or other payment to holders of our common stock through a leveraged recapitalization of us or a similar external financing event; provided that 20% of such amount shall be paid directly to ZM Private Equity Fund I, L.P. In addition, the stockholders agreement provides that we will pay an annual management fee to Corinthian Capital and ZM Equity Partners, LLC of

$800,000 in the aggregate, subject to increase from time to time by our board of directors acting in good faith.

For the period of 180 days following the effective date of a registration statement filed under the Securities Act by us in connection with an underwritten offering, subject to certain exceptions, the stockholders agreement provides that if requested by us and the underwriter, the stockholder parties to the stockholders agreement are not permitted to sell or otherwise transfer or dispose of any of our capital stock or securities convertible or exchangeable into our capital stock, except for any common stock or convertible securities included in such registration. Please refer to "Shares Eligible for Future Sale—Lock-Up Agreements" for a description of the lock-up agreements entered into by our directors and officers, the selling stockholders and the other holders of our equity securities.

Registration Rights Agreement

We are party to a Registration Rights Agreement with Corinthian SC, LLC, ZM Private Equity Fund I, L.P., ZM Private Equity Fund II, L.P. and James D. Mack, which we refer to collectively as the Holders, pursuant to which we granted the Holders certain registration rights in respect of our common stock. Subject to certain terms and conditions, the Registration Rights Agreement provides that Corinthian SC, LLC may require us to register the shares of our common stock held by it with the SEC. We are not required to effect more than three such registrations on behalf of Corinthian SC, LLC, except that at any time at which we are eligible to register shares of our common stock on Form S-3 (or any successor form), Corinthian SC, LLC shall have the right to an unlimited number of demand registrations on Form S-3. The Registration Rights Agreement also provides that if we propose to register any class of our equity securities in connection with a public offering, we are required to give each of the Holders notice of such determination and use our best efforts to register all of the shares of our common stock held by the Holders if so requested.

Tower Sales

Our Executive Chairman of the Board of Directors, James D. Mack, and our Chief Financial Officer, James M. Tholey, collectively own a 40% interest in Towers X, LLC, or Towers X. Towers X purchased one tower from us during our 2008 fiscal year for approximately $74,000, and one tower from us during our 2009 fiscal year for approximately $67,000. Towers X did not purchase any towers from us during our 2010 fiscal year or the nine months ended January 31, 2011.

Mr. Mack and Mr. Tholey collectively own a 25% interest in Towers XX, LLC, or Towers XX. Towers XX did not purchase any products from us during our 2008 or 2009 fiscal years. During our 2010 fiscal year and the nine months ended January 31, 2011, Towers XX purchased products from us for approximately $94,000 and $64,000, respectively.

Mr. Mack owns a 15% interest in Towers of Mississippi II, LLC, or TMII, which did not purchase any products from us during our 2008 or 2009 fiscal years. TMII purchased four towers from us during our 2010 fiscal year for approximately $319,000 in the aggregate. TMII purchased four towers from us for approximately $971,000 during the nine months ended January 31, 2011. Subject to the prior review and approval of our audit committee, TMII may purchase additional towers from us.

Until November 2009, when the business was sold, Mr. Mack owned 15% of Towers of Mississippi, LLC, or TMI. TMI did not purchase any products from us during our 2008 fiscal year. During our 2009 and 2010 fiscal years, TMI purchased towers from us for a total of approximately $4,511,000 and $310,000, respectively. TMI did not purchase any towers from us during the nine months ended January 31, 2011.

Accounts receivable from these entities, in the aggregate, at April 30, 2009 and 2010, and January 31, 2011 were approximately $878,000, $144,000 and $110,000, respectively.

Table of Contents

Each of these tower sales was on terms no less favorable to us than we could have obtained from unaffiliated third parties. Each of these companies engages exclusively in the tower leasing business, which is neither competitive with our business operations nor is it a business that we wish to enter.

Real Property Lease

Our President and Chief Executive Officer, Peter J. Sandore, owns a 33.3% interest in 150 Knotter Drive LLC, the landlord under the lease for our distribution center in Cheshire, Connecticut. The lease was originally for 10,000 square feet at a cost of $3,000 per month. On May 1, 2010, the lease was amended to increase the leased space to 28,000 square feet at a cost of $10,000 per month. The lease is being continued on a month-to-month basis. During fiscal 2009 and 2010 and the nine months ended January 31, 2011, we paid $0, $30,000 and $90,000, respectively, in rent under the lease to 150 Knotter Drive LLC. We entered into the original lease before Mr. Sandore became an employee of the Company.

Independent Contractor Agreement

On May 1, 2009, we entered into the Consulting Agreement with BRC, an entity controlled by Peter J. Sandore, our President and Chief Executive Officer. The Consulting Agreement had a term of one year. Mr. Sandore was not employed by us at the time we entered into the Consulting Agreement. Pursuant to the terms of the Consulting Agreement, BRC agreed to provide the services of Mr. Sandore as an advisor to our Chief Executive Officer and board of directors. In consideration of such services, we were required to pay BRC base compensation in the amount of $36,190 per month for each of May, June and July 2009, and $20,000 per month from August 2009 through April 2010. In addition to the base compensation described above, BRC was eligible to receive a commission based upon a percentage of incremental business generated by BRC through Mr. Sandore for orders received through December 31, 2010. For the year ended April 30, 2010 and the nine months ended January 31, 2011, BRC earned approximately $30,000 and $66,000, respectively, in commissions under the agreement. The Consulting Agreement terminated pursuant to its terms upon our hiring of Mr. Sandore as Chief Operating Officer on April 27, 2010. As a condition of the termination of the agreement, BRC will receive commissions earned on orders placed through December 31, 2010. The outstanding commission amount is $13,000, based on orders placed through December 31, 2010 which have not yet been invoiced.

Note Receivable

In October 2009, we entered into a note receivable with Mr. Mack for $350,000 that was due on demand and carried interest at the then-applicable federal rate for related party loans. The loan was payable in cash or through the surrender of 10,651.25 shares of our common stock owned by Mr. Mack, in Mr. Mack's sole discretion. In December 2009, Mr. Mack elected to settle the outstanding principal amount of the note by surrendering shares of our common stock to us. The fair value of the shares at the time of the loan settlement was approximately $186,000. We recognized the differential on the note balance and a gross-up amount of approximately $54,000 for taxes as compensation expense in fiscal 2010.

Transactions with Former Director

Steven Schoonover, a stockholder and a former director of ours, held, at the time of our acquisition of CellXion, a 41.3% interest in CellXion. In March 2010, we reached a settlement with the prior owners of CellXion on the amount of the contingent portion of the purchase price relating to our September 2007 acquisition of CellXion pursuant to which we agreed to pay them an aggregate of $1,937,500.

Table of Contents

From time to time, we have used an aircraft for travel purposes, which is owned by Schoonover Enterprises, LLC, an entity owned by Steven Schoonover, one of our stockholders and a former member of our board of directors. During fiscal 2009 and fiscal 2010, we paid approximately $61,000 and $130,000, respectively, in rent and certain expenses associated with the operation and maintenance of the aircraft to Schoonover Enterprises, LLC. We did not incur any expenses associated with this aircraft during the nine months ended January 31, 2011.

Former Credit Facility

Pursuant to the terms of two Loan and Security Agreements each dated May 9, 2006, D.B. Zwirn Special Opportunities Fund, L.P. ("DB Zwirn"), a former principal stockholder of ours, as a lender and agent for the lenders thereunder, agreed to provide us with a $15,000,000 revolving credit facility and term loans of $20,000,000 and $13,000,000 (the "DB Zwirn Loans"). In order to, among other things, repay the DB Zwirn Loans, we entered into a Delay Draw Credit Agreement with Dresdner Bank AG, New York and Grand Cayman Branches, under which we received proceeds of $85,000,000 on June 26, 2007 and $6,000,000 on June 27, 2007. On June 26, 2007, we repaid the DB Zwirn Loans in full, together with accrued interest and fees and a $730,000 prepayment penalty.

Our Policies Regarding Related-Party Transactions

Prior to the completion of the offering, we intend to adopt a written policy and procedures for the review, approval and ratification of transactions with related persons. The policy we plan to adopt will provide that: (i) the term "related persons" will include, among others, our executive officers and other senior level employees, directors, immediate family members of such persons and any other person that could significantly influence our policies; and (ii) transactions covered under our policy will generally include business transactions between us and a related person, including, among others, the sale of inventory or supplies to or purchase of inventory or supplies from a related person, and the supply of services to or receipt of services from a related person and will require the pre-approval of the audit committee in certain cases.

Table of Contents

PRINCIPAL AND SELLING STOCKHOLDERS

The following tables present information regarding the beneficial ownership of our common stock as of April 8, 2011 by:

•: each person, or group of affiliated persons, that is known by us to own beneficially 5% or more of our common stock;
•: each of our directors;
•: each of our executive officers named in the section of this prospectus captioned "Executive Compensation—Summary Compensation Table";
•: all our directors and executive officers as a group; and
•: each selling stockholder.

We have determined beneficial ownership in accordance with the rules of the SEC, which attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to the exercise of stock options that are either immediately exercisable or exercisable within 60 days of April 8, 2011. These shares are deemed to be outstanding and beneficially owned by the person holding those options for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.

As reflected in the tables, percentage ownership before the offering is determined using 2,635,622 shares of common stock outstanding, which is based on the number of shares outstanding as of April 8, 2011. Percentage ownership after the offering reflects the issuance of shares of common stock in the offering by us. The information assumes no exercise of the underwriters' overallotment option. Each individual or entity shown on the table has furnished information with respect to beneficial ownership. Except as otherwise noted below, the address for each beneficial owner listed on the table is c/o Sabre Industries, Inc., 1120 Welsh Road, Suite 210, North Wales, PA 19454.

Table of Contents

DESCRIPTION OF CAPITAL STOCK

The following description summarizes the terms of our capital stock. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description, you should refer to our amended and restated certificate of incorporation and bylaws, to be effective prior to the completion of the offering, which are included as exhibits to the registration statement of which this prospectus is part.

General

Upon completion of the offering, our authorized capital stock will consist of shares of common stock, par value $0.01 per share, and shares of preferred stock, par value $0.01 per share.

As of January 31, 2011, we had shares of our common stock outstanding. No shares of our preferred stock are designated, issued or outstanding.

Common Stock

Holders of our common stock are entitled to one vote for each share held of record on any matter to be voted upon by stockholders. Our amended and restated certificate of incorporation does not provide for cumulative voting in connection with the election of directors. Subject to the rights of any class of stock having a preference as to dividends, holders of shares of our common stock are entitled to receive dividends as may be declared by our board of directors from time to time in its discretion from funds legally available therefor. There are no preemptive, subscription, conversion, redemption or sinking fund provisions applicable to our common stock.

Upon any voluntary or involuntary liquidation, dissolution or winding up of our affairs, holders of shares of our common stock are entitled to share ratably in all assets remaining after payment of liabilities and amounts payable to holders of any class of stock having a preference as to liquidation. All the outstanding shares of common stock are, and the shares offered by us will be, fully paid and non-assessable.

The rights, preferences and privileges of holders of our common stock are subject to and may be affected by, the rights of the holders of any shares of preferred stock that we may designate and issue in the future.

Preferred Stock

Our amended and restated certificate of incorporation provides that our board of directors is authorized to provide for the issuance of preferred stock in one or more series and to fix the preferences, powers and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof, including the dividend rate, conversion rights, voting rights, redemption rights and liquidation preference, and to fix the number of shares to be included in any such series. Any preferred stock so issued may rank senior to our common stock with respect to the payment of dividends or amounts upon liquidation, dissolution or winding up. In addition, any such shares of preferred stock may have class or series voting rights.

Equity Incentive Awards

As of January 31, 2011, we had outstanding options to purchase shares of our common stock and shares of restricted stock. The weighted average exercise price of the outstanding options is $ per share. We have shares remaining available for issuance pursuant to our equity incentive plan.

Table of Contents

Warrants

Warrants to purchase 15,552 shares of our common stock at an exercise price of $0.01 per share are currently outstanding. The warrants expire on May 9, 2016. These warrants may be exercised at the option of the holder in whole or in part by (i) cash payment of the exercise price or (ii) exchange of the warrant for shares of our common stock equal to the value of the amount of the warrant being exchanged on the date of exchange. The exercise price and number of shares of common stock issuable upon exercise of the warrants may be adjusted in certain circumstances, including in the event of a stock dividend, stock split, combination or reclassification of outstanding shares of our common stock and upon certain issuances of additional shares of our common stock at less than fair value.

Registration Rights Agreement

Please refer to "Related-Party Transactions—Registration Rights Agreement" for a summary of our Registration Rights Agreement.

Indemnification and Limitation of Directors and Officer Liability

As permitted by Section 102 of the Delaware General Corporation Law, or DGCL, our amended and restated certificate of incorporation and bylaws limit the liability of our directors for monetary damages for breach of their fiduciary duties, except for liability that cannot be eliminated under the DGCL. Delaware law provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except liability for any of the following:

•: any breach of their duty of loyalty to the corporation or the stockholders;
•: acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;
•: unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the DGCL; or
•: any transaction from which the director derived an improper personal benefit.

This limitation of liability does not apply to liabilities arising under the federal securities laws and does not affect the availability of equitable remedies such as injunctive relief or rescission.

As permitted by Section 145 of the DGCL, our amended and restated certificate of incorporation and our bylaws also provide that we shall indemnify our directors and executive officers and may indemnify our other officers and employees and other agents to the fullest extent permitted by law and that we may advance expenses to our directors, officers and employees in connection with legal proceedings to the fullest extent permitted by the DGCL, subject to limited exceptions. We believe that indemnification under our amended and restated certificate of incorporation and bylaws covers at least negligence and gross negligence on the part of indemnified parties.

Our amended and restated bylaws also permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in this capacity, regardless of whether our amended and restated bylaws or Section 145 of the DGCL would permit indemnification. We intend to obtain directors' and officers' liability insurance to provide our directors and officers with insurance coverage for losses arising from claims based on breaches of duty, negligence, errors and other wrongful acts.

In connection with the offering, we intend to enter into separate indemnification agreements with each of our directors and executive officers, which provide for indemnification that is broader than

104

Table of Contents

the indemnification provided for in our charter documents. These agreements, among other things, provide for indemnification of our directors and executive officers for expenses, judgments, fines and settlement amounts incurred by such persons in any action or proceeding arising out of such persons' services as a director or executive officer or at our request. We believe that these provisions and agreements are necessary to attract and retain qualified persons as directors and executive officers.

The underwriting agreement also provides for indemnification by the underwriters of our officers, directors and selling stockholders for specified liabilities under the Securities Act.

Anti-Takeover Effects of Certain Provisions of Delaware Law and Our Amended and Restated Certificate of Incorporation and Bylaws

Certain provisions of the DGCL and our amended and restated certificate of incorporation and bylaws could make it more difficult to acquire us or even prevent us from being acquired by means of a tender offer, a proxy contest or otherwise, or to remove our incumbent directors and officers. These provisions, which we have summarized below, are intended to discourage certain takeover practices that could be coercive or result in inadequate takeover bids, to encourage persons seeking to acquire control of us to first negotiate a transaction with us and to enhance the likelihood of continued stability in the composition of our board of directors and executive management. We believe that the benefits of increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging takeover or acquisition proposals because, among other things, negotiation of these proposals could result in an improvement of their terms. However, these provisions could have the effect of discouraging third parties from initiating a tender offer for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts and also may have the effect of preventing changes in our executive management.

Delaware Anti-Takeover Statute

We are subject to Section 203 of the DGCL, which is an anti-takeover statute. Section 203 of the DGCL generally prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a three-year period following the time the person became an interested stockholder, unless the business combination or the transaction in which the person became an interested stockholder is approved in accordance with Section 203's requirements. In general, a "business combination" generally includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder and an "interested stockholder" is a person who (together with affiliates and associates) owns (or within three years prior to the determination of interested stockholder status did own) 15% or more of a corporation's outstanding voting stock. The applicability of this provision to us would be expected to have an anti-takeover effect with respect to transactions not approved in advance by our board of directors, including discouraging attempts that might result in a premium over the market price for your shares.

Stockholder Action by Written Consent

Our amended and restated bylaws provide that any action to be taken by our stockholders must be taken at a duly called annual or special meeting and may not be taken by written consent without a meeting.

Stockholder Meetings

Our amended and restated bylaws provide that a special meeting of our stockholders may be called only by the chairman of our board of directors, our Chief Executive Officer, our President or

105

Table of Contents

upon a resolution duly adopted by upon the affirmative vote of a majority of our entire board of directors, and not by our stockholders.

Board Size; Filling of Vacancies

Our amended and restated certificate of incorporation and bylaws provide that the number of directors on our board of directors will be fixed exclusively by our board of directors. Newly created directorships resulting from any increase in our authorized number of directors will be filled solely by the vote of our remaining directors in office. Any vacancies in our board of directors resulting from death, resignation or removal from office or other cause will be filled solely by a majority vote of our remaining directors in office.

Requirements for Advance Notification of Stockholder Nominations and Proposals

Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals and nomination of candidates for election as directors other than nominations made by or at the direction of our board of directors or a committee of our board of directors.

Listing

We have applied to list our common stock on the NASDAQ Global Select Market under the trading symbol "SABR."

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC.

SHARES ELIGIBLE FOR FUTURE SALE

Prior to the offering, there has been no public market for our common stock, and although we expect that our common stock will be approved for listing on the NASDAQ Global Select Market, we cannot assure you that there will be an active public market for our common stock following the offering. We cannot predict what effect, if any, sales of our shares in the public market or the availability of shares for sale will have on the market price of our common stock. Future sales of substantial amounts of common stock in the public market, including shares issued upon exercise of outstanding options, or the perception that such sales may occur, however, could adversely affect the market price of our common stock and also could adversely affect our future ability to raise capital through the sale of our common stock or other equity-related securities of ours at times and prices we believe appropriate.

Upon completion of the offering, based on our shares outstanding as of , shares of our common stock will be outstanding. All of the shares of common stock expected to be sold in the offering will be freely tradable without restriction or further registration under the Securities Act unless held by our "affiliates," as that term is defined in Rule 144 under the Securities Act. The remaining outstanding shares of our common will be deemed "restricted securities" as that term is defined under Rule 144. Restricted securities may be sold in the public market only if registered under the Securities Act or if those securities qualify for an exemption from registration, including exemptions provided by Rules 144 and 701 under the Securities Act, which are summarized below.

As a result of the lock-up agreements and market stand-off provisions described below and the provisions of Rules 144 or 701, and assuming no extension of the lock-up period and no exercise of the underwriters' overallotment option, the shares of our common stock that will be deemed "restricted securities" will be available for sale in the public market following the completion of the offering as follows:

•: shares will be eligible for sale on the date of this prospectus; and
•: shares will be eligible for sale upon expiration of the lock-up agreements and market stand-off provisions described below, beginning more than 180 days after the date of this prospectus.

We may issue shares of our common stock from time to time for a variety of corporate purposes, including in capital-raising activities through future public offerings or private placements, in connection with the exercise of stock options or warrants, in other issuances relating to our employee benefit plans and as consideration for future acquisitions, investments or other purposes. The number of shares of our common stock that we may issue may be significant, depending on the events surrounding such issuances. In some cases, the shares we issue may be freely tradable without restriction or further registration under the Securities Act; in other cases, we may grant registration rights covering the shares issued in connection with these issuances, in which case the holders of the common stock will have the right, under certain circumstances, to cause us to register any such shares for resale to the public.

Lock-up Agreements

We, our directors and officers, the selling stockholders and the other holders of our equity securities have agreed, subject to certain exceptions, not to offer, sell or transfer any common stock or securities convertible into or exchangeable or exercisable for common stock, other than the shares that the selling stockholders may sell in the offering, for a period ending 180 days after the date of this prospectus without first obtaining the written consent of Stifel, Nicolaus & Company, Incorporated, subject to specified exceptions and a possible extension of up to 34 additional days beyond the end of

107

Table of Contents

such period. These agreements are described below under the section captioned "Underwriting—No Sales of Similar Securities."

Stifel, Nicolaus & Company, Incorporated has advised us that it has no present intent or arrangement to release any shares subject to a lock-up, and will consider the release of any lock-up on a case-by-case basis. Upon a request to release any shares subject to a lock-up, Stifel, Nicolaus & Company, Incorporated would consider the particular circumstances surrounding the request, including, but not limited to, the length of time before the lock-up expires, the number of shares requested to be released, reasons for the request, the possible impact on the market or our common stock and whether the holder of our shares requesting the release is an officer, director or other affiliate of ours.

Rule 144

In general, under Rule 144, beginning 90 days after the date of this prospectus, a person who is not our affiliate and has not been our affiliate at any time during the preceding three months will be entitled to sell any shares of our common stock that such person has beneficially owned for at least six months, including the holding period of any prior owner other than one of our affiliates, without regard to the registration requirements of the Securities Act. Sales of our common stock by any such person would be subject to the availability of current public information about us if the shares to be sold were beneficially owned by such person for less than one year.

In addition, under Rule 144, a person may sell shares of our common stock acquired from us immediately upon the completion of the offering, without regard to the registration requirements of the Securities Act or the availability of public information about us, if:

•: the person is not our affiliate and has not been our affiliate at any time during the preceding three months; and
•: the person has beneficially owned the shares to be sold for at least one year, including the holding period of any prior owner other than one of our affiliates.

Beginning 90 days after the date of this prospectus, our affiliates who have beneficially owned shares of our common stock for at least six months, including the holding period of any prior owner other than one of our affiliates, would be entitled to sell within any three-month period a number of shares that does not exceed the greater of:

•: 1% of the number of shares of our common stock then outstanding, which will equal approximately shares immediately after the offering; and
•: the average weekly trading volume in our common stock on the NASDAQ Global Select Market during the four calendar weeks preceding the date of filing of a notice on Form 144 with respect to the sale.

Sales under Rule 144 by our affiliates are also subject to manner of sale provisions and notice requirements and to the availability of current public information about us. To the extent that shares were acquired from one of our affiliates, a person's holding period for the purpose of effecting a sale under Rule 144 would commence on the date of transfer from the affiliate.

Rule 701

In general, under Rule 701 a person who purchased shares of our common stock pursuant to a written compensatory plan or contract and who is not deemed to have been one of our affiliates during the immediately preceding 90 days may sell those shares in reliance upon Rule 144, but without being required to comply with the notice, manner of sale or public information requirements or volume limitation provisions of Rule 144. Rule 701 also permits affiliates to sell their Rule 701 shares under Rule 144 without complying with the holding period requirements of Rule 144. All holders of Rule 701

108

Table of Contents

shares, however, are required to wait until 90 days after the date of this prospectus before selling such shares pursuant to Rule 701.

As of January 31, 2011, shares of our outstanding common stock had been issued in reliance on Rule 701 as a result of exercises of stock options and shares had been issued upon grant of restricted stock awards. of these shares, however, are subject to lock-up agreements or market stand-off provisions as discussed above, and, as a result, these shares will only become eligible for sale at the earlier of the expiration of the lock-up period or upon obtaining the consent of the underwriters to release all or any portion of these shares from the lock-up agreements.

Stock Options; Restricted Stock

As of January 31, 2011, options to purchase a total of shares of our common stock and shares of restricted stock were outstanding. We intend to file one or more registration statements on Form S-8 under the Securities Act to register the offer and sale of all shares of our common stock subject to outstanding stock options and all shares issued or issuable under our stock plans. We expect to file the registration statement covering these shares after the date of this prospectus, which will permit the resale of such shares by persons who are non-affiliates of ours in the public market without restriction under the Securities Act, subject, with respect to certain of the shares, to the provisions of the lock-up agreements and market stand-off provisions described above.

MATERIAL UNITED STATES TAX CONSIDERATIONS
FOR NON-UNITED STATES HOLDERS OF COMMON STOCK

The following is a general discussion of material U.S. federal income and estate tax considerations with respect to the ownership and disposition of shares of our common stock applicable to non-U.S. holders. In general, a "non-U.S. holder" is any holder other than:

•: an individual citizen or resident of the United States;
•: a corporation or entity taxable as a corporation created or organized in or under the laws of the United States or any political subdivision thereof;
•: an estate, the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source;
•: a trust if (1) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) it has a valid election in effect to be treated as a U.S. person; or
•: a partnership (or an entity treated as a partnership for U.S. tax purposes).

If a partnership (or an entity treated as a partnership for U.S. tax purposes, such as a limited liability company) holds shares of our common stock, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. Any partner in a partnership holding shares of our common stock should consult its own tax advisors.

This discussion is based on current provisions of the Internal Revenue Code of 1986, as amended, or the Internal Revenue Code, final, temporary or proposed Treasury regulations promulgated thereunder, judicial opinions, published positions of the Internal Revenue Service, or the IRS, and all other applicable authorities, all of which are subject to change, possibly with retroactive effect. We assume in this discussion that a non-U.S. holder holds shares of our common stock as a capital asset (generally, property held for investment).

This discussion does not address all aspects of U.S. federal income and estate taxation that may be important to a particular non-U.S. holder in light of that non-U.S. holder's individual circumstances, nor does it address any aspects of U.S. state or local or non-U.S. taxes. This discussion also does not consider any specific facts or circumstances that may apply to a non-U.S. holder and does not address the special tax rules applicable to particular non-U.S. holders, including without limitation:

•: banks, insurance companies or other financial institutions;
•: pass-through entities (e.g., partnerships), or persons who hold our common stock through pass-through entities;
•: tax-exempt organizations;
•: tax-qualified retirement plans;
•: brokers or dealers in securities or currencies;
•: traders in securities that elect to use a mark-to-market method of accounting for their securities holdings;
•: controlled foreign corporations or passive foreign investment companies;
•: regulated investment companies;
•: persons that own, or are deemed to own, more than 5% of our capital stock (except to the extent specifically set forth below);

110

Table of Contents

•: certain former citizens or long-term residents of the U.S.; and
•: persons that will hold common stock as a position in a hedging transaction, "straddle" or "conversion transaction" for tax purposes.

We have not obtained, nor do we intend to obtain, an opinion of counsel with respect to the U.S. federal income or estate tax consequences to a non-U.S. holder of the purchase, ownership or disposition of our common stock. We urge prospective investors to consult with their own tax advisors regarding the U.S. federal, state, local, non-U.S. and other tax considerations of acquiring, holding and disposing of shares of our common stock.

Dividends

We currently intend to retain future earnings, if any, to finance the expansion of our business and do not expect to pay any cash distributions on our common stock. Distributions we pay, if any, to a non-U.S. holder out of our current or accumulated earnings and profits generally will constitute dividends for U.S. federal income tax purposes. To the extent distributions exceed our current and accumulated earnings and profits for U.S. federal income tax purposes, they will constitute a tax-free return of capital and will reduce your adjusted tax basis in our common stock, but not below zero, and, to the extent they exceed your adjusted tax basis in our common stock, they will be treated as capital gain, subject to the tax treatment described below in "—Gain on Sale or Other Disposition of Common Stock."

Dividends paid to a non-U.S. holder generally will be subject to U.S. withholding tax at a rate of 30% or such lower rate as may be provided by an applicable income tax treaty. To obtain a reduced rate of withholding under a treaty, a non-U.S. holder must (1) provide us with an IRS Form W-8BEN certifying the non-U.S. holder's entitlement to benefits under that treaty or (2) if common stock is held through foreign intermediaries, satisfy the relevant certification requirements of applicable Treasury regulations.

Special rules apply if the dividends are effectively connected with a trade or business carried on by the non-U.S. holder within the United States or, if a treaty applies, are attributable to a permanent establishment or fixed base of the non-U.S. holder within the United States. Dividends effectively connected with this U.S. trade or business, or, if a treaty applies, attributable to such a permanent establishment or fixed base of a non-U.S. holder, generally will not be subject to U.S. withholding tax if the non-U.S. holder files certain forms, including IRS Form W-8ECI or any successor form, with the payor of the dividend. Such dividends, although not subject to withholding tax, generally will be subject to U.S. federal income tax on a net income basis, in the same manner as if the non-U.S. holder were a resident of the United States. A non-U.S. holder that is a corporation may be subject to an additional "branch profits tax" at a rate of 30%, or a reduced rate as may be specified by an applicable income tax treaty, on its "effectively connected earnings and profits," subject to certain adjustments.

A non-U.S. holder of shares of our common stock that is eligible for a reduced rate of U.S. withholding tax, but fails to provide the necessary certification, may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS.

Gain on Sale or Other Disposition of Common Stock

In general, a non-U.S. holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of the holder's shares of our common stock unless:

•: the gain is effectively connected with a trade or business carried on by the non-U.S. holder within the United States, or, if required by an applicable income tax treaty as a condition to subjecting a non-U.S. holder to United States income tax on a net basis, the gain is attributable to a permanent establishment or fixed base of the non-U.S. holder maintained in the United States, in which case a non-U.S. holder will be subject to U.S. federal income tax on any gain realized upon the sale or other disposition on a net income basis, in the same

111

Table of Contents

manner as if the non-U.S. holder were a resident of the United States. Furthermore, the branch profits tax discussed above also may apply if the non-U.S. holder is a corporation;

•: the non-U.S. holder is an individual and is present in the United States for a period or periods aggregating 183 days or more in the taxable year of disposition and certain other tests are met, in which case a non-U.S. holder will be subject to a flat tax at a rate of 30% or such lower rate as may be provided by an applicable income tax treaty on any gain realized upon the sale or other disposition, which tax may be offset by U.S. source capital losses; or
•: we are or have been a U.S. real property holding corporation, or USRPHC, for U.S. federal income tax purposes at any time within the shorter of the five-year period preceding the disposition or the non-U.S. holder's holding period, in which case a non-U.S. holder will be subject to U.S. federal income tax on any gain realized upon the sale or other disposition on a net income basis, in the same manner as if the non-U.S. holder were a resident of the United States. We do not believe that we are or have been a USRPHC, and we do not anticipate becoming a USRPHC. If we have been in the past or were to become a USRPHC at any time during this period, generally gains realized upon a disposition of shares of our common stock by a non-U.S. holder that did not directly or indirectly own more than 5% of our common stock during this period would not be subject to U.S. federal income tax, provided that our common stock is "regularly traded on an established securities market" (within the meaning of Section 897(c)(3) of the Internal Revenue Code). Our common stock will be treated as regularly traded on an established securities market during any period in which it is listed on a registered national securities exchange or any over-the-counter market, including the NASDAQ Global Select Market.

U.S. Federal Estate Tax

Shares of our common stock that are owned or treated as owned by an individual non-U.S. holder at the time of death will be includible in the individual's gross estate for U.S. federal estate tax purposes, unless an applicable treaty provides otherwise, and therefore may be subject to U.S. federal estate tax.

Backup Withholding, Information Reporting and Other Reporting Requirements

Generally, we must report annually to the IRS and to each non-U.S. holder the amount of dividends paid to such holder, and the tax withheld with respect to such dividends. These information reporting requirements apply even if withholding was not required because the dividends were effectively connected dividends or withholding was reduced or eliminated by an applicable income tax treaty. This information may be made available under the provisions of a specific treaty or agreement with the tax authorities in the country in which the non-U.S. holder resides or is established.

U.S. backup withholding tax is imposed at a current rate of 28% (which rate currently is scheduled to increase to 31% for taxable years beginning on or after January 1, 2013) on certain payments to persons that fail to furnish the information required under the U.S. information reporting requirements. A non-U.S. holder of shares of our common stock will be subject to this backup withholding tax on any dividends we pay unless the holder certifies, among other things, its status as a non-U.S. holder (which is generally provided by furnishing an IRS Form W-8BEN, or other applicable form), or otherwise establishes an exemption, provided we or the paying agent have no actual knowledge or reason to know that the beneficial owner is a United States person. The certification procedures required to claim a reduced rate of withholding under an income tax treaty will satisfy the certification requirements necessary to avoid backup withholding tax as well.

Under the Treasury regulations, the payment of proceeds from the disposition of shares of our common stock by a non-U.S. holder made to or through a U.S. office of a broker generally will be subject to information reporting and backup withholding unless the beneficial owner certifies, among

112

Table of Contents

other things, its status as a non-U.S. holder (which is generally provided by furnishing an IRS Form W-8BEN, or other applicable form), or otherwise establishes an exemption, provided the broker has no knowledge or reason to know that the beneficial owner is a U.S. person. The payment of proceeds from the disposition of shares of our common stock by a non-U.S. holder made to or through a non-U.S. office of a broker generally will not be subject to backup withholding and information reporting, except as noted below. In the case of proceeds from a disposition of shares of our common stock by a non-U.S. holder made to or through a non-U.S. office of a broker that is:

•: a U.S. person, including a foreign branch of such person;
•: a "controlled foreign corporation" for U.S. federal income tax purposes;
•: a foreign person 50% or more of whose gross income from certain periods is effectively connected with a U.S. trade or business; or
•: a foreign partnership if at any time during its tax year (1) one or more of its partners are U.S. persons who, in the aggregate, hold more than 50% of the income or capital interests of the partnership or (2) the foreign partnership is engaged in a U.S. trade or business;

information reporting, but not backup withholding, will apply in a manner similar to U.S. brokers.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder can generally be refunded or credited against the non-U.S. holder's U.S. federal income tax liability, if any, provided that the required information is furnished to the IRS in a timely manner and the required procedures are followed.

New Legislation Relating to Foreign Accounts

Newly enacted legislation may impose withholding taxes on certain types of payments made to "foreign financial institutions" and certain other non-U.S. entities. Under this legislation, the failure to comply with additional certification, information reporting and other specified requirements could result in withholding tax being imposed on payments of dividends and sales proceeds to foreign intermediaries and certain non-U.S. holders. The legislation imposes a 30% withholding tax on dividends on, or gross proceeds from the sale or other disposition of, our common stock paid to a foreign financial institution or to a foreign non-financial entity, unless (i) the foreign financial institution undertakes certain diligence and reporting obligations or (ii) the foreign non-financial entity either certifies that it does not have any substantial U.S. owners or furnishes identifying information regarding each substantial U.S. owner. If the payee is a foreign financial institution, it must enter into an agreement with the U.S. Treasury requiring, among other things, that it undertake to identify accounts held by certain U.S. persons or U.S.-owned foreign entities, annually report certain information about such accounts, and withhold 30% on payments to account holders whose actions prevent it from complying with these reporting and other requirements. The legislation would apply to payments made after December 31, 2012. Prospective investors should consult their tax advisors regarding this legislation.

THE FOREGOING IS A GENERAL DISCUSSION OF MATERIAL U.S. FEDERAL TAX CONSIDERATIONS AND IS NOT TAX ADVICE. ACCORDINGLY, EACH PROSPECTIVE HOLDER OF SHARES OF OUR COMMON STOCK SHOULD CONSULT HIS, HER OR ITS OWN TAX ADVISER WITH RESPECT TO THE FEDERAL, STATE, LOCAL AND NON-U.S. TAX CONSEQUENCES OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK.

Subject to the terms and conditions set forth in the purchase agreement, the underwriters have agreed, severally and not jointly, to purchase all of the shares sold under the purchase agreement if any of these shares are purchased. If an underwriter defaults, the purchase agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the purchase agreement may be terminated.

We and the selling stockholders have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares, and other conditions contained in the purchase agreement, such as the receipt by the underwriters of officer's certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

The representatives have advised us and the selling stockholders that the underwriters propose initially to offer the shares to the public at the public offering price set forth on the cover page of this prospectus and to dealers at that price less a concession not in excess of $ per share. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

Table of Contents

Overallotment Option

The selling stockholders have granted an option to the underwriters to purchase up to an additional shares at the public offering price, less the underwriting discount. The underwriters may exercise this option for 30 days from the date of this prospectus solely to cover any overallotments. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the purchase agreement, to purchase a number of additional shares proportionate to that underwriter's initial amount reflected in the above table.

No Sales of Similar Securities

We and the selling stockholders, our executive officers and directors, and our other existing security holders have agreed not to sell or transfer any common stock or securities convertible into, exchangeable for, exercisable for, or repayable with common stock, for a period ending 180 days after the date of this prospectus without first obtaining the written consent of Stifel, Nicolaus & Company, Incorporated. Specifically, we and these other persons have agreed, with certain limited exceptions, not to directly or indirectly:

•: offer, pledge, sell or contract to sell any common stock,
•: sell any option or contract to purchase any common stock,
•: purchase any option or contract to sell any common stock,
•: grant any option, right or warrant for the sale of any common stock,
•: lend or otherwise dispose of or transfer any common stock,
•: request or demand that we file a registration statement related to the common stock, or
•: enter into any swap or other agreement that transfers, in whole or in part, the economic consequence of ownership of any common stock, whether any such swap or transaction is to be settled by delivery of shares or other securities, in cash or otherwise.

This lock-up provision applies to common stock and to securities convertible into or exchangeable or exercisable for or repayable with common stock. It also applies to common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition. In the event that either (x) during the last 17 days of the lock-up period referred to above, we issue an earnings release or material news or a material event relating to us occurs or (y) prior to the expiration of the lock-up period, we announce that we will release earnings results or become aware that material news or a material event will occur during the 16-day period beginning on the last day of the lock-up period, the restrictions described above will continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

NASDAQ Global Select Market Listing

We expect the shares to be approved for listing on the NASDAQ Global Select Market under the symbol "SABR."

Before the offering, there has been no public market for our common stock. The initial public offering price will be determined through negotiations between us, the selling stockholders and the representatives. In addition to prevailing market conditions, the factors to be considered in determining the initial public offering price are:

•: the valuation multiples of publicly traded companies that the representatives believe to be comparable to us,

115

Table of Contents

•: our financial information,
•: the history of, and the prospects for, our company and the industries in which we compete,
•: an assessment of our management, its past and present operations, and the prospects for, and timing of, our future revenues,
•: the present state of our development,
•: other relevant or appropriate factors, and
•: the above factors in relation to market values and various valuation measures of other companies engaged in activities similar to ours.

An active trading market for the shares may not develop. It is also possible that after the offering the shares will not trade in the public market at or above the initial public offering price.

The underwriters do not expect to sell more than 5% of the shares in the aggregate to accounts over which they exercise discretionary authority.

Price Stabilization, Short Positions and Penalty Bids

Until the distribution of the shares is completed, SEC rules may limit underwriters and selling group members from bidding for and purchasing our common stock. However, the representatives may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.

In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. "Covered" short sales are sales made in an amount not greater than the underwriters' overallotment option described above. The underwriters may close out any covered short position by either exercising their overallotment option or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the overallotment option. "Naked" short sales are sales in excess of the overallotment option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriters in the open market prior to the completion of the offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.

Similar to other purchase transactions, the underwriters' purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the NASDAQ Global Select Market, in the over-the-counter market or otherwise.

In addition, neither we, the selling stockholders nor any of the underwriters makes any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Electronic Offer, Sale and Distribution of Shares

In connection with the offering, certain of the underwriters or securities dealers may distribute prospectuses by electronic means, such as e-mail. In addition, the underwriters may facilitate Internet distribution for the offering to certain of their Internet subscription customers. The underwriters may allocate a limited number of shares for sale to their online brokerage customers. An electronic prospectus is available on the Internet web sites maintained by the respective underwriters.

Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

intermediary, other than offers made by the underwriters which constitute the final offering of shares contemplated in this prospectus.

For the purposes of this provision, and your representation below, the expression an "offer to the public" in relation to any shares in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and any shares to be offered so as to enable an investor to decide to purchase any shares, as the same may be varied in that Relevant Member State by any measure implementing the Prospectus Directive in that Relevant Member State and the expression "Prospectus Directive" means Directive 2003/71/EC and includes any relevant implementing measure in each Relevant Member State.

Each person in a Relevant Member State who receives any communication in respect of, or who acquires any shares under, the offer of shares contemplated by this prospectus will be deemed to have represented, warranted and agreed to and with us, the selling stockholders and each underwriter that:

(A): it is a "qualified investor" within the meaning of the law in that Relevant Member State implementing Article 2(1)(e) of the Prospectus Directive; and
(B): in the case of any shares acquired by it as a financial intermediary, as that term is used in Article 3(2) of the Prospectus Directive, (i) the shares acquired by it in the offering have not been acquired on behalf of, nor have they been acquired with a view to their offer or resale to, persons in any Relevant Member State other than "qualified investors" (as defined in the Prospectus Directive), or in circumstances in which the prior consent of the representatives has been given to the offer or resale; or (ii) where shares have been acquired by it on behalf of persons in any Relevant Member State other than qualified investors, the offer of those shares to it is not treated under the Prospectus Directive as having been made to such persons.

In addition, in the United Kingdom, this document is being distributed only to, and is directed only at, and any offer subsequently made may only be directed at persons who are "qualified investors" (as defined in the Prospectus Directive) (i) who have professional experience in matters relating to investments falling within Article 19 (5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended (the "Order") and/or (ii) who are high net worth companies (or persons to whom it may otherwise be lawfully communicated) falling within Article 49(2)(a) to (d) of the Order (all such persons together being referred to as "relevant persons").

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders
Sabre Industries, Inc.

We have audited the accompanying consolidated balance sheets of Sabre Industries, Inc. and subsidiaries (the "Company") as of April 30, 2009 and 2010, and the related consolidated statements of operations, stockholders' equity and comprehensive income, and cash flows for each of the three years in the period ended April 30, 2010. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Sabre Industries, Inc. and subsidiaries as of April 30, 2009 and 2010, and the results of their operations and their cash flows for each of the three years in the period ended April 30, 2010, in conformity with accounting principles generally accepted in the United States.
