NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except per share data)

(Unaudited)

NOTE 1. Basis of Presentation

The accompanying interim unaudited Condensed Consolidated Financial Statements have been prepared by Rudolph Technologies, Inc. (the “Company” or “Rudolph”) and in the opinion of management reflect all adjustments, consisting of normal recurring accruals, necessary for their fair presentation in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Preparing financial statements requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Actual amounts could differ materially from reported amounts. The interim results for the three and six month ~~period~~periods ended ~~March~~June 3130, 2019 are not necessarily indicative of results to be expected for the entire year or any future periods. This interim financial information should be read in conjunction with the financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 (“2018 10-K”) filed with the Securities and Exchange Commission (“SEC”) on February 15, 2019. The accompanying Condensed Consolidated Balance Sheets at December 31, 2018 has been derived from the audited consolidated financial statements included in the 2018 10-K.

Recent Accounting Pronouncements

Recently Adopted

Effective January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) No. 2018-07, “Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting.” This ASU expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. An entity should apply the requirements of Topic 718 to nonemployee awards except for specific guidance on inputs to an option pricing model and the attribution of cost. The ASU is effective for the fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The adoption of ASU No. 2018-07 did not have a material impact on the Company’s consolidated financial position, results of operations, and cash flows.

Effective January 1, 2019, the Company adopted ASU No. 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The new guidance allows companies to reclassify stranded tax effects resulting from the Tax Cuts and Jobs Act (the “Tax Act”) from accumulated other comprehensive income to retained earnings. The guidance also requires certain new disclosures regardless of a company’s election. The standard is effective for annual periods beginning after December 15, 2018 and for interim periods within those annual periods, with earlier adoption permitted. The adoption of ASU No. 2018-02 did not have a material impact on the Company’s consolidated financial position, results of operations, and cash flows.

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” ASU No. 2016-02 requires that lessees recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and lease liability. On January 1, 2019, the Company adopted ASU No. 2016-02 using the modified retrospective method which applies the provisions of the standard at the effective date without adjusting the comparative periods presented. The Company also elected the package of practical expedients.

There was not a cumulative-effect adjustment to the Company’s beginning retained earnings as a result of adopting ASU No. 2016-02. The Company has recognized additional operating lease assets and obligations of $14.4 million as of January 1, 2019. The Company elected to not reassess prior conclusions related to the identification, classification and accounting for initial direct costs for leases that commenced prior to January 1, 2019. For additional disclosure and detail, see Note 56 of the Notes to the Condensed Consolidated Financial Statements, “Leasing Arrangements.”

Recently Issued

In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU is part of the FASB’s larger disclosure framework project intended to improve the effectiveness of financial statement footnote disclosure. ASU No. 2018-13 modifies required fair value disclosures related primarily to level 3 investments. This ASU is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. The adoption of ASU No. 2018-13 is not expected to have a material effect on the Company’s consolidated financial position, results of operations, and cash flows.

Table of Contents

In May 2017, the FASB issued ASU No. 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting.” This ASU amends the scope of modification accounting for share-based payment arrangements and provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under Accounting Standards Codification (“ASC”) 718. The ASU is effective for the fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. The adoption of ASU No. 2017-09 is not expected to have a material effect on the Company’s consolidated financial position, results of operations, and cash flows, if any.

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” This ASU eliminates Step 2 from the goodwill impairment test. Accordingly, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss will be recognized in an amount equal to the excess, limited to the total amount of goodwill allocated to the reporting unit. The ASU is effective for the fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. The Company is currently evaluating the effect the adoption of ASU No. 2017-04 will have on its consolidated financial position, results of operations, and cash flows, if any.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which ~~introduced~~represents a new ~~guidance~~credit ~~for~~loss standard that will change the ~~accounting~~impairment model for ~~credit~~most ~~losses~~financial onassets ~~instruments~~and ~~within~~certain ~~its~~other ~~scope~~financial instruments. ~~Given~~ ~~the~~Specifically, ~~breadth~~this ofguidance ~~that~~will ~~scope~~require entities to utilize a new “expected loss” model as it relates to trade receivables, ~~this~~notes ~~ASU~~receivable and other commitments to extend credit held by a reporting entity. In addition, entities will ~~impact~~be ~~both~~required ~~financial~~to ~~services~~recognize ~~and~~an ~~non~~allowance for estimated credit losses on available-~~financial~~for-sale ~~services~~debt ~~entities~~securities, regardless of the length of time that a security has been in an unrealized loss position. ~~The~~ ~~standard~~This isguidance will be effective for ~~fiscal~~annual ~~years~~reporting periods beginning after December 15, ~~2020~~2019, including interim periods within those annual reporting periods, and early adoption is permitted. The Company is currently evaluating the ~~effect~~potential impact that the adoption of ~~ASU~~this ~~No.~~guidance ~~2016-13~~may ~~will~~ have on its consolidated financial position, results of operations, and cash flows~~, if any~~.

Recently issued accounting guidance not discussed above is not applicable.

NOTE 2. ~~Fair~~ ~~Value~~Business ~~Measurements~~Combinations

On June 23, 2019, the Company entered into an agreement and plan of merger to combine in an all-stock merger of equals transaction with Nanometrics Incorporated (“Nanometrics”), a provider of advanced process control metrology and software analytics. The transaction was unanimously approved by the board of directors of both companies and is subject to the satisfaction of customary closing conditions, including receipt of customary regulatory approvals and approval by the shareholders of each company. The Company anticipates the merger to close in the second half of 2019. Under the terms of the agreement, Rudolph stockholders will receive 0.8042 shares of Nanometrics common stock for each share of Rudolph common stock. Upon completion of the merger, current Nanometrics stockholders will own approximately 50% of the combined company and current Rudolph stockholders will own approximately 50% of the combined company. In addition, if the merger agreement is terminated prior to completion of the merger, a termination fee of $26.0 million if the merger agreement is terminated under circumstances specified in the merger agreement. During the three months ended June 30, 2019, the Company accrued $2.5 million of direct costs associated with the merger.

NOTE 3. Fair Value Measurements

The Company applies a three-level valuation hierarchy for fair value measurements. This hierarchy prioritizes the inputs into three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability. Level 3 inputs are unobservable inputs based on management’s assumptions used to measure assets and liabilities at fair value. A financial asset’s or liability’s fair value measurement classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Level 1 inputs are based on quoted market prices that are available in active markets. The Company does not have any recurring financial assets and liabilities that are recorded in its Condensed Consolidated Balance Sheets as of March 31, 2019 and December 31, 2018 that are classified as Level 1 inputs.

The Company’s available-for-sale debt securities classified as Level 2 are valued using observable inputs to quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. The foreign currency forward contracts are primarily measured based on the foreign currency spot and forward rates quoted by the banks or foreign currency dealers. Investment prices are obtained from third party pricing providers, which model prices utilizing the above observable inputs, for each asset class.

Level 3 liabilities consisted of contingent consideration related to an acquisition for which the Company uses a discounted cash flow model to value these liabilities. The Level 3 assumptions used in the discounted cash flow model for the contingent consideration included projected revenue, timing of cash flows and estimates of discount rates of 9.2% and 9.4% for the ~~three~~six months ended ~~March~~June 3130, 2019 and 2018, respectively. A significant decrease in the projected revenue or increase in discount rates could result in a significantly lower fair value measurement for the contingent consideration.

This table presents a reconciliation of all liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the ~~three~~six months ended ~~March~~June 3130, 2019:

Fair Value of Other Financial Instruments

The carrying value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximates fair value because of the short-term maturity of these instruments. The estimated fair value of these obligations is based primarily on a market approach, comparing the Company’s interest rates to those rates the Company believes it would reasonably receive upon re-entry into the market. Judgment is required to estimate the fair value, using available market information and appropriate valuation methods.

The carrying amount of the convertible notes receivable approximates fair value based on current interest rates for instruments with similar characteristics. Convertible notes receivable are initially recognized at fair value. The Company does not subsequently adjust the fair value of these convertible notes receivable unless it is determined that the convertible notes receivable are impaired. The Company considers the issuer’s financial condition, payment history, and other relevant factors when assessing the collectability of a convertible note and to reserve the portion of such convertible note for which collection does not appear likely. Interest income is recognized as earned.

NOTE 34. Marketable Securities

The Company has evaluated its investment policies and determined that all of its marketable securities, which are comprised of debt securities, are to be classified as available-for-sale. The Company’s available-for-sale debt securities are carried at fair value, with the unrealized gains and losses reported in Stockholders’ equity under the caption “Accumulated other comprehensive loss.” Realized gains and losses on available-for-sale securities are included in “Other expense (income)” on the Condensed Consolidated Statements of Operations. The Company records other-than-temporary impairment charges for its available-for-sale debt securities when it intends to sell the securities, it is more-likely-than not that it will be required to sell the securities before a recovery, or when it does not expect to recover the entire amortized cost basis of the securities. The cost of securities sold is based on the specific identification method.

The Company has determined that the gross unrealized losses on its marketable securities at ~~March~~June 3130, 2019 and December 31, 2018 are temporary in nature. The Company reviews its investment portfolio to identify and evaluate marketable securities that have indications of possible impairment. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value has been less than the cost basis, credit quality and the Company’s ability and intent to hold the securities for a period of time sufficient to allow for any anticipated recovery in market value.

10At June 30, 2019 and December 31, 2018, marketable securities are categorized as follows:

NOTE 4. Derivative Instruments and Hedging Activities

The Company, when it considers it to be appropriate, enters into forward contracts to hedge the economic exposures arising from foreign currency denominated transactions. At March 31, 2019 and December 31, 2018, these contracts included the future sale of Japanese Yen to purchase U.S. dollars. Derivative instruments are measured at fair value and recognized as either, “Prepaid expenses and other current assets” or “Other current liabilities” in the Condensed Consolidated Balance Sheets with changes in the net derivatives position reflected in operating cash flows. The foreign currency forward contracts were entered into by the Company’s Japanese subsidiary to economically hedge a portion of certain intercompany obligations. The forward contracts are not designated as hedges for accounting purposes and increases in the fair value of $45 for the three months ended March 31, 2019 and a decrease in the fair value of $433 for the three months ended March 31, 2018, are recorded under the caption “Other expense (income), net” in the Condensed Consolidated Statements of Operations.

NOTE 6. Leasing Arrangements

The Company leases space for its corporate headquarters, manufacturing, sales and service operations, vehicles and information technology equipment under operating leases. All of the Company’s leases are operating leases. The Company elected not to apply Accounting Standard Codification Topic 842 (“ASC 842”) to arrangements with lease terms of less than 12 months. Operating lease right-of-use assets and obligations are reflected within the captions “Operating lease right-of-use assets,” “Current operating lease obligations,” and “Non-current operating lease obligations,” respectively, on the Condensed Consolidated Balance Sheets.

Operating lease costs were $~~877~~869 and $1,746 during the three and six months ended ~~March 31~~June 30, 2019. These costs are primarily related to long-term operating leases, but also include immaterial amounts for short-term leases less than 12 months. Operating lease costs are recognized on a straight-line basis over the terms of the leases.

Additional operating lease right-of-use assets of $10222 were recognized as non-cash asset additions that resulted from new operating lease liabilities ~~during~~as of the ~~three~~six months ended ~~March 31~~June 30, 2019. Cash paid for amounts included in the ~~present~~measurement ~~value~~ of operating lease liabilities was $~~846~~1,656 during the ~~three~~six months ended ~~March 31~~June 30, 2019 and is included in operating cash flows.

The Company often has the option to renew lease terms for buildings and other assets. The exercise of lease renewal options are generally at the Company’s sole discretion. In addition, certain lease arrangements may be terminated prior to their original expiration date at the Company’s discretion. The Company evaluates renewal and termination options at the lease commencement date to determine if it is reasonably certain to exercise the option on the basis of economic factors. The weighted average of the remaining lease term for operating leases as of ~~March 31~~June 30, 2019 was 87.19 years.

The discount rate implicit within the Company’s leases is generally not determinable and therefore the Company determines the discount rate based on its incremental borrowing rate. The incremental borrowing rate for our leases is ~~determined based on the lease term in which lease payments are made. The weighted average discount rate used to measure operating lease liabilities as of March 31, 2019 was 4.7%.~~

The following table presents information about the amount and timing of cash flows arising from the Company’s operating leases as of March 31, 2019:

NOTE 8. Convertible Notes Receivable

The Company entered into a convertible loan agreement with Simax Precision Technologies Limited (“Simax”) on May 31, 2018. Under the agreement, Simax may borrow from the Company up to $15,000 in multiple promissory notes, subject to limitations. The Company expects to be a supplier of lithography modules to Simax which is focused on the manufacture, sale and service of lithography systems.

The convertible notes will bear a rate of interest of 4.25% per annum payable on a semi-annual basis. The convertible notes provide the Company with the option to convert the outstanding indebtedness into equity. If the Company does not elect to exercise its option to convert the notes into equity, Simax will repay the principal amount outstanding and any outstanding interest in equal installments beginning on the fifth anniversary of the loan date and continuing on a quarterly basis over the next three years.

As of ~~March 31~~June 30, 2019, the convertible notes receivable balance was $5,000 with accrued interest of $93105.

NOTE 910. Commitments and Contingencies

Intellectual Property Indemnification Obligations

The Company has entered into agreements with customers that include limited intellectual property indemnification obligations that are customary in the industry. These guarantees generally require the Company to compensate the other party for certain damages and costs incurred as a result of third-party intellectual property claims arising from these transactions. The nature of the intellectual property indemnification obligations prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay to its customers. Historically, the Company has not made any indemnification payments under such agreements and no amount has been accrued in the accompanying Condensed Consolidated Financial Statements with respect to these indemnification guarantees.

Table of Contents

Warranty Reserves

The Company generally provides a warranty on its products for a period of 12 to 15 months against defects in material and workmanship. The Company estimates the costs that may be incurred during the warranty period and records a liability in the amount of such costs at the time revenue is recognized. The Company’s estimate is based primarily on historical experience. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. Settlements of warranty reserves are generally associated with sales that occurred during the 12 to 15 months prior to the quarter-end and warranty accruals are related to sales during the same year.

Changes in the Company’s warranty reserves are as follows:

	Three Months Ended March 31,
	Six Months Ended June 30,

NOTE 1011. Revenue

Table of Contents

Revenue is recognized when control of the promised goods or services are transferred to the Company’s customers in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those goods or services. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

Contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices charged to customers or the expected cost-plus margin.

Disaggregated Revenue

The following table presents the Company’s revenue disaggregated by revenue source:

See Note 1617 of the Notes to the Condensed Consolidated Financial Statements for additional discussion of the Company’s disaggregated revenue in detail.

Systems Revenue

Revenue from systems is recognized when the Company transfers control of the product to the customer. To indicate transfer of control, the Company must have a present right to payment, legal title must have passed to the customer and the customer must have the significant risks and rewards of ownership. The Company generally transfers control for system sales when the customer or the customer’s agent picks up the system at the Company’s facility. Payment for the majority of the Company’s systems have 80-90% of the invoice amount due within 30 days and the remaining amount due upon completion of installation, recalibration and qualification by the customer. The Company provides an assurance warranty on its systems for a period of twelve to fifteen months against defects in material and workmanship. The Company provides for the estimated cost of product warranties at the time revenue is recognized.

Depending on the terms of the systems arrangement, the Company may also defer the recognition of a portion of the consideration expected to be received because the Company has to satisfy a future obligation (e.g., installation, training and extended warranties). The Company uses an observable price to determine the standalone selling price for separate performance obligations or a cost-plus margin approach when one is not available.

Software Licensing, Support and Maintenance Revenue

Revenue from software licenses provides the customer with a right to use the software as it exists when made available to the customer. Revenue from software licenses are recognized upfront at the point in time when the software is made available to the customer. Revenue from licensing support and maintenance is recognized as the support and maintenance are provided, which is over the contract period. Payment for software licensing, support and maintenance is generally due in 30 days.

Parts Revenue

Revenue from parts is recognized when the Company transfers control of the product, which typically occurs when the Company ships the product from its facilities to the customer. Payment for parts is generally due in 30 days.

Services Revenue

Table of Contents

Revenue from services primarily consists of service contracts, which provide additional maintenance coverage beyond the Company’s assurance warranty on its products, service labor, consulting and training. Revenue from service contracts is recognized ratably over the term of the service contract. Revenue from service labor, consulting and training is recognized as services are performed. Payment for services is generally due in 30 days.

Contract Liabilities

The Company records contract liabilities when the customer has been billed in advance of the Company completing its performance obligations. These amounts are recorded as deferred revenue in the Consolidated Balance Sheets.

Changes in deferred revenue were as follows:

	Three Months Ended						Six Months Ended
	March 31,

NOTE 11. Share-Based Compensation

Restricted Stock Unit Activity

A summary of the Company’s restricted stock unit activity with respect to the ~~three~~six months ended ~~March~~June 3130, 2019 is as follows:

	Number of Shares			Weighted Average Grant Date Fair Value
Nonvested at December 31, 2018		794		$	19.51
Granted		~~288~~318		$	23.5059
Vested		(~~124~~274	)	$	1416.2191
Forfeited		(517	)	$	2023.2803
Nonvested at March 31, 2019		953		$	21.40
Nonvested at June 30, 2019		821		$	21.88

Included in the number of shares granted in the table directly above are 55 market performance-based restricted stock units (“MPRSUs”) granted to executives in 2019. Vesting of these MPRSUs is contingent upon the Company meeting certain total shareholder return (“TSR”) levels as compared to a select peer group over three years from the year granted. The 2019 MPRSUs cliff vest at the end of the three-year period and have a maximum potential to vest at 200% (111 shares) based on TSR performance. The related share-based compensation expense is determined based on the estimated fair value of the underlying shares on the date of grant and is recognized straight-line over the vesting term. The estimated fair value per share of the MPRSUs was $26.72.

As of ~~March~~June 3130, 2019 and December 31, 2018, there was $1412,~~034~~787 and $9,517 of total unrecognized compensation cost related to restricted stock units granted under the Company’s stock plans, respectively. That cost is expected to be recognized over a weighted average period of 2.64 years and 2.1 years for each of the respective periods.

Provision for income taxes	$	1,219		$	2,544
Effective tax rate		13.9	%		14.4	%

The income tax provision for the three months ended March 31, 2019 was computed based on the Company’s annual forecast of profit by jurisdiction and forecasted effective tax rate for the year. The changes in the Company’s effective tax rate for the three months ended March 31, 2019 as compared to the same period in 2018 are primarily due to changes in the mix of forecasted earnings by jurisdictions, Section 162 (m) adjustment and the tax-exempt interest. The Company’s recorded effective tax rate is less than the U.S. statutory rate primarily due to a projected Foreign Derived Intangible Income Deduction from the Tax Act and federal research and development tax credits..

NOTE 15. Earnings Per Share

Basic earnings per share is calculated using the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed in the same manner and also gives effect to all dilutive common stock equivalent shares outstanding during the period. Potential common shares that would have the effect of increasing diluted earnings per share are considered to be anti-dilutive. In accordance with U.S. GAAP, these shares were not included in calculating diluted earnings per share.

The following table sets forth the weighted average number of restricted stock units that have been excluded from the calculation of diluted earnings per share as their effect would have been anti-dilutive:

	Three Months Ended March 31,

Critical Accounting Policies

A critical accounting policy is defined as one that is both material to the presentation of our condensed consolidated financial statements and requires management to make difficult, subjective or complex judgments that could have a material effect on our financial condition or results of operations. Specifically, these policies have the following attributes: (1) we are required to make judgments and assumptions about matters that are highly uncertain at the time of the estimate; and (2) different estimates we could reasonably have used, or changes in the estimate that are reasonably likely to occur, could have a material effect on our financial position and results of operations.

Estimates and assumptions about future events and their effects cannot be determined with certainty. We base our estimates on historical experience and on various other assumptions believed to be applicable and reasonable under the circumstances. These estimates may change as new events occur, as additional information is obtained and as our operating environment changes. In addition, management is periodically faced with uncertainties, the outcomes of which are not within our control and will not be known for prolonged periods of time. Certain of these uncertainties are discussed in our 2018 10-K in the Items entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Based on a critical assessment of our accounting policies and the underlying judgments and uncertainties affecting the application of those policies, we believe that our condensed consolidated financial statements are fairly stated in accordance with U.S. GAAP and provide a fair presentation of our financial position and results of operations.

For more information, please see our critical accounting policies as previously disclosed in our 2018 10-K.

Recent Developments

On June 23, 2019, we entered into an agreement and plan of merger to combine in an all-stock merger of equals transaction with Nanometrics, a provider of advanced process control metrology and software analytics. The transaction was unanimously approved by the board of directors of both companies and is subject to the satisfaction of customary closing conditions, including receipt of customary regulatory approvals and approval by the shareholders of each company. We anticipate the merger to close in the second half of 2019. Under the terms of the agreement, our stockholders will receive 0.8042 shares of Nanometrics common stock for each share of our common stock. Upon completion of the merger, current Nanometrics stockholders will own approximately 50% of the combined company and our current stockholders will own approximately 50%, of the combined company. In addition, each party may be required to pay a termination fee of $26.0 million if the merger agreement is terminated under circumstances specified in the merger agreement. During the three months ended June 30, 2019, we accrued $2.5 million of direct costs associated with the merger.

Overview

We are a worldwide leader in the design, development, manufacture and support of process control tools that perform macro-defect inspections and metrology, lithography systems, and process control analytical software used by semiconductor and advanced packaging device manufacturers. We deliver comprehensive solutions throughout the semiconductor fabrication process with our families of proprietary products that provide critical yield-enhancing information, enabling microelectronic device manufacturers to drive down costs and time to market of their devices. We provide process and yield management solutions used in both wafer processing facilities, often referred to as “front-end” and device packaging and test facilities, or “back-end” manufacturing, through a portfolio of standalone systems for macro-defect inspection, lithography, probe card test and analysis, and transparent and opaque thin film measurements. All of our systems feature sophisticated software and production-worthy automation. In addition, our advanced process control software portfolio includes powerful solutions for standalone tools, groups of tools, or factory-wide suites to enhance productivity and achieve significant cost savings. Our systems are backed by worldwide customer service and applications support.

Our business is affected by the annual spending patterns of our customers on semiconductor capital equipment. The amount that our customers devote to capital equipment spending depends on a number of factors, including general worldwide economic conditions, as well as other economic drivers such as personal computers, mobile devices, data centers, artificial intelligence and automotive sales. Current forecasts by industry analysts for the semiconductor device manufacturing industry project capital equipment spending to be down 1516-1820% for 2019 as compared to 2018. Our revenue and profitability tend to follow the trends of certain segments within the semiconductor market.

Historically, a significant portion of our revenue in each quarter and year has been derived from sales to relatively few customers, and we expect this trend to continue. For the ~~three~~six months ended ~~March~~June 3130, 2019 and for the years ended December 31, 2018, 2017 and 2016, aggregate sales to customers that individually represented at least five percent of our revenue accounted for 3943.61%, 18.3%, 27.2%, and 34.5% of our revenue, respectively.

We do not have purchase contracts with any of our customers that obligate them to continue to purchase our products, and they could cease purchasing products from us at any time. A delay in purchase or cancellation by any of our large customers could cause quarterly revenue to vary significantly. In addition, during any given quarter, a significant portion of our revenue may be derived from the sale of a relatively small number of systems. The following table presents the average selling price range for our systems:

System		Average Selling Price Per System
Process control		$250,000 to $2.6 million
Lithography steppers		$2.6 million to $8.5 million

Table of Contents

A significant portion of our revenue is derived from customers outside of the United States. A substantial portion of our international sales are denominated in U.S. dollars. We expect that revenue generated from customers outside of the United States will continue to account for a significant percentage of our revenue.

The sales cycle for our systems typically ranges from six to twenty-four months and can be longer when our customers are evaluating new technology. Due to the length of these cycles, we invest significantly in research and development and sales and marketing in advance of generating revenue related to these investments.

Total systems and software revenue decreased $1329.78 million for the ~~three~~six months ended ~~March~~June 3130, 2019, as compared to the ~~three~~six months ended ~~March~~June 3130, 2018. Process control system revenue decreased $820.9 million for the ~~three~~six months ended ~~March~~June 3130, 2019, as compared to the same period in 2018, primarily due to lower inspection system sales in the 2019 period. Lithography system revenue decreased $48.52 million for the ~~three~~six months ended ~~March~~June 3130, 2019, as compared to the same period in 2018, primarily due to the shipment of a JetStep G system during the first half of 2018, which has a higher average selling price. Software revenue decreased $0.47 million for the ~~three~~six months ended ~~March~~June 3130, 2019, as compared to the same period in 2018, primarily due to lower process control software sales. Systems revenue generated by our latest product releases and major enhancements in each of our product families amounted to 7275% and 74% of total revenue for the three and six months ended ~~March~~June 3130, 2019, as compared to 7675% of total revenue for both the three and six months ended ~~March~~June 3130, 2018. The year-over-year increase in total parts and services revenue for the ~~three~~six months ended ~~March~~June 3130, 2019 is primarily due to increased spending by our customers on system upgrades and repairs of existing systems. Parts and services revenue are generated from parts sales, maintenance service contracts, system upgrades, as well as from time and material billable service calls.

Deferred revenue of $78.52 million was recorded in the Condensed Consolidated Balance Sheets under the caption “Deferred revenue” and $1.2 million was recorded under the caption “Other non-current liabilities” at ~~March~~June 3130, 2019. Deferred revenue primarily consisted of $67.07 million for deferred maintenance agreements and $21.7 million for outstanding deliverables.

Gross Profit. Our gross profit has been and will continue to be affected by a variety of factors, including manufacturing efficiencies, provision for excess and obsolete inventory, pricing by competitors or suppliers, new product introductions, production volume, customization and reconfiguration of systems, international and domestic sales mix, system and software product mix and parts and service margins. Our gross profit was $3231.09 million and $63.9 million for the three and six months ended ~~March~~June 3130, 2019, as compared to $4241.47 million and $84.2 million for the same period in 2018. Our gross profit represented 5251.69% and 5852.02% of our revenue for the three and six months ended ~~March~~June 3130, 2019 and 53.9% and 55.9% for the same periods in 2018. The decrease in gross profit as a percentage of revenue for the ~~three~~six months ended ~~March~~June 3130, 2019, as compared to the same period in 2018, is primarily due to lower volume of system and software sales as well as product mix.

Operating Expenses. Major components of operating expenses include research and development, as well as selling, general and administrative expenses.

Research and Development. Our research and development expenses were $1213.71 million and $25.8 million for the three and six months ended ~~March~~June 3130, 2019, as compared to $1112.87 million and $24.5 million for the same ~~period~~periods in 2018. Research and development expenses represented 21.2% and 21.1% of our revenue for the three and six months ended June 30, 2019, respectively, as compared to 16.4% and 16.3% of revenue for the prior year periods. Research and development expenses increased for the year-over-year periods due to increases in new product initiatives.

22Selling, General and Administrative. Our selling, general and administrative expenses were $13.1 million and $24.4 for the three and six months ended June 30, 2019, as compared to $11.9 million and $24.7 million for the same periods in 2018. Selling, general and administrative expenses represented 21.2% and 19.9% of our revenue for the three and six months ended June 30, 2019, respectively, as compared to 15.4% and 16.4% of our revenue for the same periods in 2018.

Our future effective income tax rate depends on various factors, such as impacts of the Tax Act, possible further tax legislation, the geographic composition of our pre-tax income, the amount of our pre-tax income as business activities fluctuate, non-deductible expenses incurred in connection with acquisitions, and research and development tax credits as a percentage of aggregate pre-tax income.

We currently have a partial valuation allowance recorded for certain foreign and state loss and credit carryforwards where the realizability of such deferred tax assets is substantially in doubt. Each quarter we assess the likelihood that we will be able to recover our deferred tax assets primarily relating to state research and development credits. We consider available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance. As a result of our analysis, we concluded that it is more likely than not that a portion of our net deferred tax assets will not be realized. Therefore, we continue to provide a valuation allowance against certain net deferred tax assets. We continue to monitor available evidence and may reverse some or all of the valuation allowance in future periods, if appropriate.

Liquidity and Capital Resources

At ~~March~~June 3130, 2019, we had $~~170~~179.89 million of cash, cash equivalents and marketable securities and $~~311~~319.94 million in working capital. At December 31, 2018, we had $175.1 million of cash, cash equivalents and marketable securities and $305.9 million in working capital.

Operating activities ~~used~~provided $19.68 million in net cash and cash equivalents for the ~~three~~six months ended ~~March~~June 3130, 2019. The net cash and cash equivalents ~~used~~provided by operating activities during the ~~three~~six months ended ~~March 31~~June 30, 2019 resulted primarily from ~~a decrease in cash used in operating assets and liabilities of $13.6 million, offset by~~ net income, adjusted to exclude the effect of non-cash operating charges of $1220.09 million~~. This~~, partially offset by a decrease ~~was~~in ~~primarily~~cash ~~attributed~~provided tofrom ~~increases~~operating inassets ~~inventories~~and liabilities of $11.1 million. Operating activities provided $49.65 million in net cash and cash equivalents for the ~~three~~six months ended ~~March~~June 3130, 2018. The net cash and cash equivalents provided by operating activities during the ~~three~~six months ended ~~March~~June 3130, 2018 resulted primarily from net income, adjusted to exclude the effect of non-cash operating charges of $1939.51 million, partially offset by a decrease in cash provided from operating assets and liabilities of $1429.96 million.

Net cash and cash equivalents of $97.27 million were used in investing activities during the ~~three~~six months ended ~~March~~June 3130, 2019 primarily for the purchase of marketable securities of $2238.12 million and capital expenditures of $12.37 million, offset by proceeds from sales of marketable securities of $1433.32 million. Net cash and cash equivalents used in investing activities of $419.21 million during the ~~three~~six months ended ~~March~~June 3130, 2018 resulted from the purchase of marketable securities of $57105.17 million and capital expenditures of $12.42 million, offset by proceeds from sales of marketable securities of $5488.48 million.

Net cash and cash equivalents used in financing activities during the ~~three~~six months ended ~~March~~June 3130, 2019 of $12.35 million, which resulted from payment of contingent consideration for acquired business of $1.1 million, the purchase of shares of our common stock under share repurchase authorizations of $0.7 million and tax payments related to shares withheld for share-based compensation plans of $0.67 million, partially offset by proceeds from sales of shares through share-based compensation plans of $0.2 million. For the ~~three~~six months ended ~~March~~June 3130, 2018, financing activities used $01.75 million, which resulted from payment of contingent consideration for acquired business of $1.0 million, and tax payments related to shares withheld for share-based compensation plans of $01.80 million, partially offset by proceeds from sales of shares through share-based compensation plans of $0.15 million.

From time to time, we evaluate whether to acquire new or complementary businesses, products and/or technologies. We may fund all of or a portion of the price of these investments or acquisitions in cash, stock, or a combination of cash and stock.

We entered into a convertible loan agreement with Simax Precision Technologies Limited (“Simax”) on May 31, 2018. Simax may borrow up to $15 million in multiple promissory notes from us, subject to limitations. We expect to be a supplier of lithography modules to Simax which is focused on the manufacture, sale and service of lithography systems. As of

~~supplier~~June ~~of lithography modules to Simax which is focused on the manufacture~~30, ~~sale and service of lithography systems. As of March 31,~~ 2019, Simax has borrowed $5 million from us under the convertible loan agreement. See Note 78 in the accompanying Notes to the Condensed Consolidated Financial Statements included in this Form 10-Q for further information.

In October 2018, the Board of Directors approved a new share repurchase authorization, which allows us to repurchase up to $40 million worth of shares of our common stock. The authorization provides for repurchases to be made in the open market or through negotiated transactions from time to time. The share repurchase authorization has no expiration date and may be discontinued at any time. During the three and six months ended ~~March 31~~June 30, 2019, we repurchased no shares and 37 thousand shares of common stock under our share repurchase authorization and those shares were subsequently retired. At ~~March 31~~June 30, 2019, there was $32,494 available for future share repurchases. Share repurchases under this plan are currently suspended until the completion of the merger with Nanometrics. For further information, see Note 1718. Shares Repurchase Authorization and Note 2. Business Combinations in the accompanying Notes to the Condensed Consolidated Financial Statements included in this Form 10-Q.

We have a credit agreement with a bank that provides for a line of credit that is secured by the marketable securities we have with the bank. We are permitted to borrow up to 70% of the value of eligible securities held at the time the line of credit is accessed. As of ~~March~~June 3130, 2019, the available line of credit was approximately $9693.70 million with an available interest rate of 4.0%. The credit agreement is available to us until such time that either party terminates the arrangement at its discretion. To date, we have not utilized this line of credit.

Our future capital requirements will depend on many factors, including the timing and amount of our revenue and our investment decisions, which will affect our ability to generate additional cash. We expect that our existing cash, cash equivalents, marketable securities and availability under our line of credit will be sufficient to meet our anticipated cash requirements for working capital, capital expenditures and other cash needs for the next 12 months following the filing of this Form 10-Q. Thereafter, if cash generated from operations and financing activities is insufficient to satisfy our working capital requirements, we may seek additional funding through bank borrowings, sales of securities or other means. There can be no assurance that we will be able to raise any such capital on terms acceptable to us or at all.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate and Credit Market Risk

We are exposed to changes in interest rates and market liquidity including our investments in certain available-for-sale debt securities. Our available-for-sale securities consist of fixed and variable rate income investments, such as municipal notes, municipal bonds and corporate bonds. We continually monitor our exposure to changes in interest rates, market liquidity and credit ratings of issuers for our available-for-sale securities. It is possible that we are at risk if interest rates, market liquidity or credit ratings of issuers change in an unfavorable direction. The magnitude of any gain or loss will be a function of the difference between the fixed or variable rate of the financial instrument and the market rate, and our financial condition and results of operations could be materially affected. Based on a sensitivity analysis performed on our financial investments held as of ~~March~~June 3130, 2019, an immediate adverse change of 10% in interest rates (e.g., a change from 3.00% to 3.30%) would result in an immaterial decrease in the fair value of our available-for-sale debt securities and would not have a material impact on our consolidated financial position, results of operations or cash flows.

Foreign Currency Risk

A substantial portion of our systems and software sales are denominated in U.S. dollars with the exception of Japan. As a result, we have relatively little exposure to foreign currency exchange risk with respect to these sales. Substantially all of our sales in Japan are denominated in Japanese yen. From time to time, we may enter into forward exchange contracts to economically hedge a portion, but not all, of the existing and anticipated foreign currency denominated transactions expected to occur within 12 months. The change in fair value of the forward exchange contracts is recognized under the caption “Other (income) expense” in the Condensed Consolidated Statements of Operations for each reporting period. As of ~~March~~June 3130, 2019, we had ~~twenty-three~~eleven forward exchange contracts outstanding with a total notional contract value of $52.80 million. We do not use derivative financial instruments for trading or speculative purposes.

We have branch operations in Taiwan, Singapore and South Korea and wholly-owned subsidiaries in Europe, Japan and China. Our international subsidiaries and branches operate primarily using local functional currencies. Our exposure to foreign currency exchange rate fluctuations arise from intercompany balances between our U.S. headquarters and that of our foreign owned entities. Our intercompany balances are denominated in U.S. dollars. Since each foreign entity’s functional currency is generally denominated in its local currency, there is exposure to foreign exchange risk when the foreign entity’s intercompany balance is remeasured at a reporting date, resulting in transaction gains or losses. The intercompany balance, exposed to foreign currency risk, as of ~~March~~June 3130, 2019 was approximately $2125.69 million. A hypothetical change of 10% in the relative value of the U.S. dollar versus local functional currencies could result in approximately $01.43 million in foreign ~~currency exchange losses / (gains) which would be recorded as non-operating expense in other expense (income) in our~~

currency exchange losses / (gains) which would be recorded as non-operating expense in other expense (income) in our Condensed Consolidated Statements of Operations. We cannot accurately predict future exchange rates or the overall impact of future exchange rate fluctuations on our business, results of operations and financial condition.

Item 4. Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time period specified in SEC rules and forms. These controls are procedures are also designed to ensure that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating disclosure controls and procedures, we have recognized that any control and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Management is required to exercise judgment in evaluating its controls and procedures.

Scope of the Controls Evaluation

The evaluation of our disclosure controls and procedures included a review of the controls’ objectives and design, our implementation of the controls and the effect of the controls on the information generated for use in this Form 10-Q. In the course of the evaluation, we sought to identify data errors, control problems or acts of fraud and confirm that appropriate corrective actions, if any, including process improvements, were being undertaken. This type of evaluation is performed on a quarterly basis so that the conclusions of management, including the CEO and CFO, concerning the effectiveness of the controls can be reported in our Quarterly Reports on Form 10-Q and in our Annual Reports on Form 10-K. Many of the components of our disclosure controls and procedures are also evaluated on an ongoing basis by other personnel in our accounting, finance, internal audit and legal functions. The overall goals of these various evaluation activities are to monitor our disclosure controls and procedures and to modify them on an ongoing basis as necessary. A control system can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of inherent limitations in a cost -effective control system, misstatements due to error or fraud may occur and not be detected.

Conclusions

As of ~~March~~June 3130, 2019, an evaluation of our disclosure controls and procedures was carried out under the supervision and with the participation of our management, including the CEO and CFO. Based on this evaluation, the CEO and CFO have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of the end of the period covered by this Form 10-Q.

Changes in Internal Control over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the Company’s quarter ended ~~March~~June 3130, 2019 that have materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.

There are risks and uncertainties associated with our proposed merger with Nanometrics.

On June 23, 2019, the Company entered into an agreement and plan of merger (the “Merger Agreement”) with Nanometrics. Completion of the proposed merger is subject to various conditions, and the proposed merger may not occur even if we obtain stockholder approval.

Completion of the merger is subject to certain closing conditions, including, among other things, the (1) approval by the stockholders of Nanometrics of the issuance of the shares of Nanometrics common stock pursuant to the Merger Agreement, (2) approval by the stockholders of Nanometrics of an amendment and restatement of Nanometrics’ certificate of incorporation to increase the number of authorized shares of Nanometrics common stock, (3) the adoption by our stockholders of the Merger Agreement, (4) authorization for listing on the New York Stock Exchange of the shares of Nanometrics common stock (including the shares to be issued in the proposed merger), subject to official notice of issuance, (5) the receipt of required regulatory approvals, (6) effectiveness of a registration statement on Form S-4 with respect to the shares of Nanometrics common stock to be issued in connection with the proposed merger and (7) the absence of any order, injunction, decree or other legal restraint preventing, or any proceeding brought by a governmental authority challenging, the completion of the proposed merger or making the completion of the proposed merger illegal. Each party’s obligation to consummate the proposed merger is also subject to other specified customary conditions, including (1) the representations and warranties of the other party being true and correct as of the date of the Merger Agreement and as of the closing date of the proposed merger, generally subject to an overall material adverse effect qualification, (2) the performance in all material respects by the other party of its obligations under the Merger Agreement required to be performed on or prior to the date of the closing of the proposed merger, (3) receipt by such party of an opinion from its counsel of its obligations to the effect that the proposed merger will qualify as a reorganization within the meaning of Section 368(a) of the Code and (4) the absence of a continuing material adverse effect with respect to the other party. We cannot provide any assurance that these conditions will be met or waived, or that we will be able to successfully consummate the proposed merger as provided for under the Merger Agreement, or at all.

If the proposed merger is not completed, our stock price likely will fall to the extent that the current market price of our common stock reflects an assumption that a transaction will be completed. In addition, we may be required to pay a termination fee of $26 million if the Merger Agreement is terminated under circumstances specified in the Merger Agreement.

In this regard, we face risks and uncertainties due both to the pendency of the proposed merger, as well as the potential failure to consummate the proposed merger, including:

•

diversion of management time and resources in connection with the proposed merger;

•

the occurrence of any event, change or other circumstances that could give us or Nanometrics the right to terminate the Merger Agreement;

•

the outcome of any legal proceedings that may be instituted against us, Nanometrics or our respective directors and officers with respect to the proposed merger;

•

the risk that we or Nanometrics may not obtain the required stockholder approvals on the expected schedule or at all;

•

the ability to obtain regulatory approvals and satisfy other closing conditions to the proposed merger in a timely manner or at all, including the risk that regulatory approvals required for the proposed merger are not obtained or are obtained subject to conditions that are not anticipated;

•

delay in closing the proposed merger;

•

difficulties and delays in integrating our business with Nanometrics’ business or fully realizing any anticipated cost savings or other benefits expected from the proposed merger;

•

business disruptions from the proposed merger that may harm our business or Nanometrics’ business, including current plans and operations;

•

any announcement relating to the proposed transaction could have adverse effects on our ability or the ability of Nanometrics to retain and hire key personnel or maintain relationships with suppliers and customers, or on our or Nanometrics’ operating results and businesses generally;

•

the risk that the announcement of the proposed transaction could have adverse effects on the market price of our common stock or Nanometrics’ common stock and the uncertainty as to the long-term value of the common stock of the combined company following the proposed merger; and

•

certain restrictions during the pendency of the proposed merger that may impact our ability or the ability of Nanometrics to pursue certain business opportunities or strategic transactions.

In addition, we have incurred, and will continue to incur, significant costs, expenses and fees for professional services and other transaction costs in connection with the proposed merger, and these fees and costs are payable by us regardless of whether the proposed merger is consummated.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

In October 2018, the Board of Directors approved a new share repurchase authorization, which allows us to repurchase up to $40 million worth of shares of our common stock. The authorization provides for repurchases to be made in the open market or through negotiated transactions from time to time. The share repurchase authorization has no expiration date and may be discontinued at any time. During the three and six months ended ~~March 31~~June 30, 2019, we repurchased 0 and 37.5 thousand shares of common stock under our share repurchase authorization and those shares were subsequently retired. At ~~March 31~~June 30, 2019, there was $32.5 million available for future share repurchases. Share repurchases under this plan are currently suspended until the completion of the merger with Nanometrics. For further information, see Note 1718. Shares Repurchase Authorization and Note 2. Business Combinations in the accompanying Notes to the Condensed Consolidated Financial Statements.

In addition to our share repurchase program, we withhold common stock shares associated with net share settlements to cover tax withholding obligations upon the vesting of restricted stock unit awards and stock option exercises under the Company’s equity incentive program. During the three and six months ended ~~March 31~~June 30, 2019, we withheld 276.3 thousand and 33.6 thousand shares through net share settlements. For the three and six month ~~period~~periods ended ~~March~~June 3130, 2019, net share settlements cost $0.62 million and $0.7 million, respectively. Please refer to Note 1112 of the Notes to the Condensed Consolidated Financial Statements for further discussion regarding our equity incentive plan.
