Our Company

We are an innovative global financial technology company that develops and operates electronic markets for the trading of listed cash equity securities in the United States and Europe and listed equity options in the United States. In addition to being the third largest exchange operator in the United States after NYSE Euronext and The NASDAQ OMX Group, Inc., based on total market share of the markets that we operate, we operate the second largest pan-European multilateral trading facility, or MTF. For the second quarter of 2011, we had a 10.8% share of the U.S. equity market and a 3.9% share of the U.S. equity options market. In Europe, for the same period, we had a 5.6% share of European trading in the securities available for trading on BATS Europe. For the six months ended June 30, 2011 and the year ended December 31, 2010, we derived 91.5% and 96.8%, respectively, of our total revenues from the trading of listed cash equities securities in the United States. In February 2011, we signed a definitive agreement to acquire, subject to regulatory approval, Chi-X Europe the operator of the largest pan-European MTF. For the second quarter of 2011, Chi-X Europe had a 17.4% share of European trading in the securities available for trading on Chi-X Europe.

In the United States, we operate two national securities exchanges, BZX and BYX. Both trade listed cash equity securities and exchange-traded products, such as exchange-traded funds, or ETFs, but each targets different market segments by offering different pricing alternatives. BZX also operates a market for trading listed equity options. In Europe, our MTF offers trading in listed cash equity securities from within 25 European indices, in addition to ETFs, exchange-traded commodities and international depositary receipts. Our platform is designed to facilitate price discovery by encouraging the quoting of competitive, displayed prices. Our platform also offers opportunities to post undisplayed, or “dark,” trading interest on our U.S. and European order books, and in Europe, we operate a separate dark pool.

Our principal objective is to make markets better by minimizing inefficiencies and mitigating trade execution risk for market participants. We minimize inefficiencies in part by offering low-cost, rapid, trade execution. We mitigate trade execution risk through offering ultra-low latency order handling through our trading system. In particular, by offering ultra-low latency order handling, our members can very quickly place, modify or cancel orders on our markets. This ability gives our members greater control over their orders, enabling them to rapidly respond to changing market conditions and mitigate trade execution risk. Unlike traditional market operators, we are a technology company at our core. We developed, own and operate the BATS trading platform. Our proprietary platform powers all of our markets and is designed to offer one of the fastest and most reliable trading systems available.

Our History

We were formed in 2005 as an alternative to the New York Stock Exchange, or NYSE, and The NASDAQ Stock Market, or NASDAQ, in response to increased consolidation among U.S. listed cash equity market centers. In January 2006, we launched our electronic communication network, or ECN, a type of alternative trading system, or ATS, which initially focused on the trading of NASDAQ-listed securities. We began trading in American Stock Exchange (now NYSE Amex)-listed securities in May 2006 and in NYSE-listed securities in February 2007. We entered the European market in October 2008 when we launched our MTF, BATS Europe. In November 2008, we converted our ECN to a national securities exchange, BZX, which allowed us to participate in and earn market data fees from the U.S. tape plans, reduce our clearing costs and operate a primary listings business, which we recently announced plans to launch. In February 2010, we expanded into a new asset class by offering trading of listed equity options on BZX. In order to grow our U.S. market share, in October 2010, we launched BYX, a second national securities exchange for trading listed cash equity securities.

Industry Overview

Significant regulatory and technological developments have transformed the markets in which we operate and have been the primary drivers of our growth and development:

•

U.S. Listed Cash Equity Securities. Several regulatory developments, together with innovations in technology and improvements in the speed of communication, have fundamentally changed the way U.S. listed cash equity markets operate. Notable developments that encouraged the creation of alternative markets, like our original ECN, included:

the adoption of the “order handling” rules in 1996, which facilitated the growth of ECNs as alternatives to national securities exchanges for displaying and executing orders;

the move to decimal pricing in 2000, which resulted in narrower trading spreads, providing automated market makers with an advantage over traditional market makers; and

the adoption of Regulation NMS in 2005, which provided price protection for each exchange’s best displayed quotes that are electronically accessible for immediate trade execution, and resulted in a dramatic shift to electronic trading as exchanges automated their trading systems to take advantage of this price protection.

•

European Listed Equity Securities. The implementation of the Market in Financial Instruments Directive, or MiFID, in 2007 marked a fundamental change in the European market for trading listed cash equity securities. MiFID was designed to increase competition in pan-European trading and authorized the creation of MTFs. In particular, to create competition among markets, MiFID abolished the “concentration rule,” which required firms to route orders only to national stock exchanges, and extended the concept of “passporting,” which allowed firms authorized to carry on business in one European Economic Area, or EEA, member state to carry on business in other EEA member states.

•

U.S. Listed Equity Options. The most significant recent changes within the U.S. listed equity options market have been the move to penny-increment price quotes and the shift away from the traditional pricing model for executing trades. The conversion of the U.S. listed equity options market from nickel- or dime-increment price quotes to penny-increment price quotes began in January 2007 and has contributed to significant growth in overall options market volume, particularly among electronic traders. Additionally, the traditional exchange pricing model in the U.S. listed equity options market is increasingly being supplanted by a pricing model common in the U.S. listed cash equities market that we believe encourages more aggressive competition and better price discovery.

Our Competitive Strengths

As a result of these industry developments, new trading centers like ours are better able to compete against incumbent exchanges based on technology, customer experience and price. We believe that the following competitive strengths position us well to capitalize on these industry dynamics:

•

Leading Proprietary Technology Platform. Unlike traditional market centers, we are a technology company at our core. We developed, own and operate the BATS trading platform, which we designed to optimize reliability, speed, scalability and versatility.

Our trading platform has experienced very low downtime, as demonstrated by the fact that for the six months ended June 30, 2011 and 2010, BZX was immediately and automatically accessible 99.904% and 99.998% of the time, respectively. We believe that this reliability gives our customers an additional incentive to use our platform to mitigate trade execution risk, especially in times of extreme market volatility.

Our average latency, which measures the time that it takes for us to process an order message, has decreased 87.6% from over 930 microseconds in January 2007 to approximately 120 microseconds in the second quarter of 2011.

For the second quarter of 2011, BZX processed approximately 24,000 order messages per second on average. At times, BZX has processed as many as 300,000 order messages per second, and in testing, our platform has demonstrated its ability to process more than one million order messages per second on a sustained basis.

In order to continuously implement new enhancements to our platform, new releases of software are deployed multiple times per month. Because we use the same technology platform across all of our markets, new releases can be deployed simultaneously in all of our markets.

•

Significant Operating Leverage. The scalability of our technology platform and the efficiency of our operations allow us to continue to grow with limited additional capital investment. We use technology to leverage our products and employees across multiple asset classes and geographies. As a result, we are able to operate with lower overhead than many incumbent exchanges. In addition, as a new business, we are not burdened by legacy infrastructure. With only 117 employees globally as of June 30, 2011, including 82 at our headquarters in the Kansas City area, we have captured substantial market share from traditional exchanges in the United States and Europe while maintaining substantially lower fixed costs.

•

Commitment to Competitive and Innovative Pricing. Due to our operating leverage, we are able to profitably employ an aggressive, low-spread pricing strategy, which we believe provides us with an important competitive advantage. In addition, we have employed innovative, and in some cases, disruptive pricing strategies to increase our market share. In connection with launching new markets, we have often offered pricing specials, which may generate short-term losses, but generally result in significant growth in long-term market share as customers have continued to use our markets even after pricing specials end. For example, after our pricing special in January 2007, our market share of trading in NASDAQ-listed cash equity securities increased from 4.9% at the beginning of that month to 9.6% at the end of that month and averaged 8.0% per month for the remainder of that year. In addition, we recently began providing customers who execute a specified minimum volume with more favorable pricing for orders posted on certain of our markets that improve the then current national best bid or best offer for a particular listed equity option or listed cash equity security. This in turn provides better execution prices for other customers. We initiated such pricing on our U.S. listed equity options market in January 2011, and our share of the U.S. equity options market increased from 0.7% for the month of December 2010 to 4.3% for the month of June 2011. BYX and BZX also initiated such pricing for listed cash equity securities, effective May 1, 2011 and July 1, 2011, respectively.

•

Demonstrated Ability to Rapidly Execute on Market Opportunities. We have demonstrated an ability to quickly and successfully capitalize on new opportunities in the United States and internationally:

we were originally founded in June 2005 and, with just 13 employees, launched trading approximately seven months later;

we executed our first trades on BATS Europe in October 2008, seven months after receiving board approval to enter the European market;

when we transitioned our trading platform in the United States from an ECN to a national securities exchange, we obtained Securities and Exchange Commission, or SEC, approval in August 2008, approximately 10 months after our initial filing, and launched the exchange three months later;

we began trading listed equity options in the United States in February 2010, eight months after board approval; and

we applied to operate a second national securities exchange, BYX, in October 2009; we successfully secured SEC approval within 10 months, and we launched the exchange two months later.

•

Innovative Products and Services. As part of our commitment to deliver a differentiated customer experience, we have developed a suite of innovative order types, risk management tools and other products and services to address our customers’ needs. For example, we offer several products that enable our customers to monitor their order handling on our markets in real time, such as our user dashboard and latency reports, both of which are web-based tools designed to provide customers with real-time information about their connectivity to our platform and the speed at which their orders are processed and executed within our markets. We also operate one of the few market centers in Europe that offers routing services to other venues that publicly display quotes, or lit venues, which we believe provides an added incentive to use our market.

•

Partnership Approach with Customers. We were formed in 2005 by David Cummings, one of our directors and the chairman of Tradebot Systems, and 12 former employees of Tradebot Systems, which is a leading proprietary electronic trading firm. Through a series of investments, we also gained the sponsorship of Lime Brokerage and affiliates of Bank of America Merrill Lynch, Citi, Credit Suisse, Deutsche Bank, GETCO, J.P. Morgan, Lehman Brothers, Morgan Stanley and WEDBUSH (on January 1, 2008, Lime Brokerage transferred to Lime Brokerage Holdings LLC and its affiliates all of our Class A common stock owned by Lime Brokerage, and on June 13, 2011, WEDBUSH, Inc. acquired Lime Brokerage). As a result of investments by affiliates of our strategic investors, we benefit from access to the strategic insights and industry expertise of some of the most active market participants. In an effort to continue this collaborative relationship, we will issue high-vote Class B common stock in conjunction with this offering to our existing stockholders and institute various transfer restrictions on our common stock to be held by them following this offering. We believe that these measures will encourage continued meaningful ownership by stockholders affiliated with users of our markets following this offering. In addition, our board remains composed of members with strong industry ties who we believe will continue to provide important strategic insight and industry expertise.

•

Seasoned Management Team with a Core Focus on Technology. Our management team has extensive experience in financial market operations with a deep background in technology. In addition, a large portion of our management team has worked together for several years, and most of our founding employees continue to be employed with us. We believe that our management team has demonstrated its ability to grow our business through continued product and technological innovations and that our team of technology professionals is among the best in the industry.

Our Growth Strategies

We believe that we are well positioned to leverage our competitive strengths to enhance our market position and expand into other countries and asset classes. We continually analyze new opportunities and, in particular, intend to pursue the following growth strategies:

•

Develop Additional Products and Services to Enhance Our Market Penetration and Profitability. We believe there are significant opportunities to generate additional revenue by expanding customer access to our markets and services, offering additional trade execution choices and enhancing our market data products. For example, in Europe, we recently became the first market center to offer a multilateral interoperable clearing service, which provides trading participants with a choice of a preferred clearer from three interoperating clearing counterparties, instead of the traditional single clearing counterparty affiliated with a market center. We believe our offering of a multilateral interoperable clearing service reflects a significant step towards the reduction of clearing costs through competitive clearing in Europe. Also, we recently announced our plans to launch a primary listings business in the United States, which we expect to be a competitive alternative to the incumbent exchanges. We intend to compete with the other primary listings markets by offering simple and competitive pricing for issuers, innovative mechanisms to promote liquidity and superior customer service, including state of the art access to market insight tools and a focus on market education. In addition, while we do not currently charge for our primary real-time market data products, in 2010, we began offering new value-added market data products for a fee.

•

Expand into New Asset Classes and Broaden Our Geographic Reach. We plan to continue to expand into new asset classes and new countries where we see opportunities to leverage our technology platform to capture market share. We are currently considering a variety of opportunities, including the trading of U.S. Treasury securities and other fixed income products, futures, currencies and other derivative products. In addition, we recently entered into a memorandum of understanding with Claritas, a Brazilian asset management firm, to explore opportunities in the Brazilian market, including the potential creation of a new exchange in Brazil.

•

Leverage Chi-X Europe Acquisition. We believe that our combination with Chi-X Europe, which we expect to complete during the fourth quarter of 2011 subject to regulatory review, will further our position as a leading transatlantic exchange operator and will solidify us as a preeminent pan-European trading venue. We expect to benefit from synergies as a result of the acquisition, including the transition of Chi-X Europe to our trading platform, which we expect to be completed during the second quarter of 2012. We believe the combination will improve our competitive position, enhance our profitability through scale and cost efficiencies and provide us additional opportunities to influence European market structure developments for the benefit of our customers.

•

Pursue Strategic Opportunities. We intend to seek additional opportunities to grow through strategic alliances or acquisitions that are complementary to our business or that enable us to enter new markets or provide new products or services. Our focus will be on opportunities that we believe can enhance or benefit from our technology platform, provide significant market share and profitability and are consistent with our corporate culture. We believe that the establishment of a public trading market for our common stock will enhance our ability to pursue strategic opportunities by providing a currency with which to execute future acquisitions.

Ownership Structure, Reclassification and Stock Split

In conjunction with this offering, and pending approval by the SEC of amendments to our certificate of incorporation and bylaws pursuant to the rule filing process under Section 19(b) of the Securities Exchange Act of 1934, as amended, which we refer to as the Exchange Act, we intend to reclassify each share of our

common stock which has been designated as Voting Common Stock as seven shares of Class A common stock and three shares of Class B common stock and each share of our common stock which has been designated as Non-Voting Common Stock as seven shares of Non-Voting Class A common stock and three shares of Non-Voting Class B common stock. Immediately following such reclassification and at any time thereafter, any share of Class B common stock that is held by a stockholder who, together with such stockholder’s affiliates, owns less than 4,960,491 shares of our common stock, which we refer to as the Class B Threshold, shall, automatically and without any further action, be converted into one share of Class A common stock, and each share of Non-Voting Class B common stock that is held at any time by a stockholder who, together with such stockholder’s affiliates, does not meet the Class B Threshold shall, automatically and without any further action, be converted into one share of Non-Voting Class A common stock. As a result of the reclassification and application of the Class B Threshold, each share of treasury stock held by us will be converted into ten shares of Class A common stock.

The rights of the holders of Class A common stock, Non-Voting Class A common stock, Class B common stock and Non-Voting Class B common stock will be identical, except with respect to voting rights, transfer restrictions and conversion provisions. With respect to voting, each share of Class A common stock will be entitled to one vote per share, and each share of Class B common stock will be entitled to two and one-half votes per share. Non-Voting Class A common stock and Non-Voting Class B common stock will not be entitled to vote, except as required by applicable law. Class A common stock not sold in this offering and Non-Voting Class A common stock will be subject to a restriction on transfer for one year from the completion of this offering (provided that approximately 50% of our current stockholders’ Class A common stock and Non-Voting Class A common stock may be transferred 180 days from the completion of this offering to the extent such shares are not included in this offering), and Class B common stock and Non-Voting Class B common stock will be subject to a three-year transfer restriction, subject to certain exceptions as described in “Description of Capital Stock—Common Stock—Transfer Restrictions.” Class B common stock and Non-Voting Class B common stock will automatically convert into Class A common stock in connection with any transfer following the expiration of the three-year transfer restriction, subject to certain exceptions described in “Description of Capital Stock—Common Stock—Conversion,” or upon the death of the holder. We also have the option to convert any holder’s Class B common stock or Non-Voting Class B common stock to Class A common stock or Non-Voting Class A common stock, respectively, upon a change of control of such holder. Non-Voting Class A common stock and Non-Voting Class B common stock are convertible into Class A common stock and Class B common stock, respectively, at any time at the option of the holder, and Non-Voting Class A common stock will automatically convert into Class A common stock in connection with any transfer to anyone other than a related person of the holder following the expiration of the one-year transfer restriction. See “Description of Capital Stock.”

Immediately following the stock reclassification described above, we intend to declare a -for- stock split of all outstanding Class A common stock, Class B common stock, Non-Voting Class A common stock and Non-Voting Class B common stock.

As of June 30, 2011, nine affiliates of our customers, whom we refer to as our strategic investors, will collectively own approximately shares of our Class A common stock and approximately shares of our Class B common stock, representing approximately % of the total voting power of our outstanding capital stock. These strategic investors are affiliates of Bank of America Merrill Lynch, Citi, Credit Suisse, Deutsche Bank, GETCO, J.P. Morgan, Morgan Stanley, Tradebot Systems and WEDBUSH.

Risk Factors

Investing in our Class A common stock involves substantial risk. Please read “Risk Factors” beginning on page 13 for a discussion of certain factors you should consider in evaluating an investment in our Class A common stock. Some of these risks include:

•

intense competition with a broad range of market participants in both the United States and Europe and further consolidation and alliances among our competitors which could impair our competitive position;

•

our lack of revenue diversification, which may adversely affect our operating results and place us at a competitive disadvantage;

•

regulatory changes and changes in market structure in response to the global economic crisis, which could have a material adverse effect on our business;

•

a significant percentage of our total revenues that is generated from, and significant liquidity in our markets that is provided by, customers who are affiliates of our strategic investors, who are not contractually obligated to continue to use our services or purchase our products and who also use the services of our competitors;

•

control of us by our strategic investors, who upon completion of this offering will collectively own approximately % of the total voting power of our outstanding capital stock and, to the extent that they vote similarly, will be able, by virtue of their ability to elect our board of directors, to control our policies and operations and may have interests that differ from those of other stockholders;

•

the failure to obtain requisite regulatory approval to complete our acquisition of Chi-X Europe or the inability to successfully integrate Chi-X Europe or realize any or all of the expected benefits associated with the acquisition;

•

dependence on third-party clearing and other service providers; and

•

potential system limitations, failures or security breaches, which could harm our business.

“EBITDA” is defined as income before interest, income taxes, depreciation and amortization. Adjusted EBITDA is defined as EBITDA before stock-based compensation expense. EBITDA and Adjusted EBITDA do not represent, and should not be considered as, alternatives to net income or cash flows from operations, each as determined in accordance with generally accepted accounting principles in the United States, or U.S. GAAP. We have presented EBITDA and Adjusted EBITDA because we consider them important supplemental measures of our performance and believe that they are frequently used by analysts, investors and other interested parties in the evaluation of companies. Other companies may calculate EBITDA and Adjusted EBITDA differently than we do. EBITDA and Adjusted EBITDA have limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results as reported under U.S. GAAP.

The following is a reconciliation of net income to EBITDA and Adjusted EBITDA:

RISK FACTORS

You should carefully consider the following risks and all of the information set forth in this prospectus before investing in our Class A common stock.

Risks Relating to Our Business

We face intense competition and compete with a broad range of market participants in both the United States and Europe. Further consolidation and alliances among our competitors could impair our competitive position.

The market for trade execution services is intensely competitive in the asset classes and geographies in which we operate. Increased competition may result in a decline in our share of trading activity and a decline in our revenues from transaction fees and market data fees, thereby adversely affecting our operating results.

In the United States, the competition among exchanges and other execution venues has become more intense with regulatory changes. The U.S. listed cash equity securities marketplace has evolved dramatically in recent years following the SEC’s adoption of Regulation NMS. We compete in the U.S. listed cash equity securities market against NYSE Euronext, NASDAQ OMX, Direct Edge, other regional exchanges and several alternative trading systems, or ATSs. Market participants now have multiple venues for the execution of orders, including national securities exchanges as well as numerous over-the-counter options, including ATSs operating “dark pools” that do not publicly display quotations, ECNs and broker-dealers who internalize orders. For example, dark pool venues compete with us by offering low cost executions and differ from lit ATSs and MTFs in the degree of transparency with respect to quotes and trades they offer and in restrictions on who may access these systems. Unlike “lit” venues that publicly display orders, dark pools do not display orders publicly or privately. In addition, while dark pools are required to publicly report trade executions, unlike lit venues that are national securities exchanges, such as BZX and BYX, those public reports do not identify the dark pool responsible for the trade execution. Hence, dark pools are less transparent than lit venues. Moreover, dark pools below a certain size have discretion to offer access on discriminatory terms, effectively blocking access to certain types of market participants. These features of dark pools can appeal to trading participants who seek to minimize the public disclosure of their trading interest or limit the types of other trading participants that can access their orders. In addition, various broker-dealers internalize their order flow or route their orders to third-party ATSs. Based on publicly available data regarding reported trades, as of December 31, 2010, over-the-counter trading accounted for in excess of 30% of consolidated U.S. equity volume. If over-the-counter trading expands further, it will adversely affect our market share in the United States.

The market for execution services within listed cash equity securities in Europe has become significantly more competitive since the Market in Financial Instruments Directive, or MiFID, went into effect in 2007. MiFID created a structure for pan-European competition versus incumbent exchange monopolies throughout the European Union countries. As a result, new MTFs have emerged and have begun to capture significant market share from existing exchanges, particularly the London Stock Exchange, or LSE. Following these developments, LSE acquired a majority interest in Turquoise Global Holdings Limited, or Turquoise, an MTF that offers pan-European trading. Our major competitors in Europe, other than LSE, include NYSE Euronext, Deutsche Börse AG, or Deutsche Börse, NASDAQ OMX, SIX Swiss Exchange and Bolsas y Mercados Españoles, or BME, as well as Turquoise and, prior to the close of our pending acquisition, Chi-X Europe. Some of these competitors have themselves launched MTFs.

The market for the trading of U.S. listed equity options is also intensely competitive, with nine authorized U.S. options exchanges as of June 30, 2011 vying for market share, and is in the midst of dramatic change, driven primarily by recent regulatory changes. Our primary competitors in the options market are the Chicago Board Options Exchange, or the CBOE, NYSE Euronext, NASDAQ OMX, International Securities Exchange Holdings, Inc., or ISE, and Boston Options Exchange Group, LLC, or BOX. Moreover, some products offered uniquely by

the CBOE (for example, products based on the VIX volatility index) represent products that are not traded on our platform. In addition, some of our competitors, including NYSE Euronext, NASDAQ OMX and CBOE, offer multiple trading venues for equity options that use different pricing strategies, which allows them to potentially appeal to a broader customer base.

In recent years, the securities trading industry has witnessed increased consolidation among market participants. Additional consolidations and alliances among market participants may create larger internal liquidity pools that may attract trading volume and liquidity away from BZX, BYX and BATS Europe and, therefore, lead to decreased revenues. In addition, consolidations or alliances among our current competitors may achieve cost reductions or other increases in efficiency, which may allow our competitors to offer lower prices or better customer service than we do. For example, the recently announced potential merger of Deutsche Börse with NYSE Euronext may result in stronger competitors for us in our existing markets and may also hinder our ability to expand into new markets. For example, these post-merger competitors may be able to achieve efficiencies that allow them to offer lower transaction fees or other financial incentives, which may hinder our ability to stay competitive in the listed cash equity securities market and to penetrate the options market. In addition, these mergers may result in stronger competitors for us than the pre-merger entities as stand-alone businesses in other markets that we may decide to enter, such as futures and other derivative products.

If we are unable to compete successfully in this environment, our business, financial condition and operating results may be adversely affected. Also, if our share of total trading volumes decreases relative to our competitors, we may be less attractive to market participants as a source of liquidity, and we may lose additional trading volume and associated transaction fees and market data fees as a result.

We may face competition from our strategic investors.

Our strategic investors or their affiliates may already have or may acquire an ownership interest in competing businesses (including national securities exchanges, dark pools, MTFs, ATSs or ECNs). These businesses may compete with us, either in relation to existing product and service offerings or any diversification of our product and service offerings into new asset classes and/or new geographic locations. For example, affiliates of five of our strategic investors have a material ownership interest in Chi-X Europe. In addition, certain of our strategic investors have a material interest in another MTF, Turquoise. Furthermore, many of our strategic investors operate market-making desks, dark pools, “lit” ATSs and ECNs and smart order routers, each of which potentially competes with us.

Our market data fees and transaction fees may be reduced due to declines in our market share, trading volumes or regulatory changes, and our lack of revenue diversification may adversely affect our operating results and place us at a competitive disadvantage.

We derived 52.2% and 30.6% of our revenues less cost of revenues from market data fees and net transaction fees, respectively, for the six months ended June 30, 2011. We derived 46.4% and 44.8% of our revenues less cost of revenues from market data fees and net transaction fees, respectively, for the year ended December 31, 2010. Market data fees represent our share of tape fees from the U.S. tape plans based on a formula, required by Regulation NMS, which takes into account both trading and quoting activity. For purposes of calculating this percentage, we have not attributed any incremental costs associated with providing trading and quoting information to the U.S. tape plans. Transaction fees represent fees that we earn for trade execution on BZX (including our U.S. listed equity options market), BYX and BATS Europe, whether a trade is executed internally on BZX, BYX or BATS Europe or routed to another market center. Net transaction fees represent transaction fees less the liquidity payments and routing and clearing costs that we incurred to earn those transaction fees.

The occurrence of any event that reduces the amount of market data fees or transaction fees that we receive, whether as a result of fee reductions, declines in market share or trading volumes (or notional volume in the case of BATS Europe) or regulatory changes, will have a direct negative impact on our operating results and future profitability. For example, if our market share of U.S. listed cash equities and U.S. listed equity options trading

were to decline, our share of market data fees could also decline. In addition, if the amount of trading volume on BZX, BYX or BATS Europe or notional value traded on BATS Europe decreases, we will lose transaction fees. Moreover, market data fees could decline as a result of a reduction in the numbers of market data users, for example because of consolidation among market data subscribers or due to a decline in professional subscriptions as a result of staff reductions in the financial services industry or otherwise. For a discussion of the factors that may impact trading volumes, see “—Current economic conditions could adversely affect our business and financial condition.”

In addition, our dependence upon revenues derived solely from our transaction-based businesses may place us at a competitive disadvantage. Some of our competitors derive their revenues from more than one source as a result of more diversified product and service offerings. For example, NYSE Euronext and NASDAQ OMX realize substantial revenue from listing fees. In addition, many of our competitors also offer technology outsourcing. As a result, lower transaction fees or market data fees may impact our operating results and future profitability more significantly than our competitors’, providing them with a competitive advantage in pricing their products and services or withstanding a reduction in trading volume.

Our industry is characterized by intense price competition.

The securities trading industry is characterized by intense price competition. We may be required to adjust pricing to respond to actions by new or existing competitors, which could adversely impact operating results. We have also recently begun to compete with respect to the sale of value-added market data such as historical market data and a real-time last sale data feed. If we are unable to compete successfully with respect to the pricing of our services and products, our business, financial condition and operating results may be adversely affected. Furthermore, to attract market share, we offer “inverted” pricing specials from time to time in the United States and Europe that may adversely affect our profitability. As we do not currently have any primary listings on our exchanges (other than our expected self-listing), we do not have the liquidity associated with primary listings and must compete purely on price and technology.

Our revenues are positively correlated with overall market volume, which can be impacted by a number of factors, including market volatility.

A significant percentage of our revenue is tied directly to the volume of securities traded on our markets. Trading volume on our markets can be influenced by a number of factors, including market volatility. In late 2008, we experienced a period of record high trading volume and volatility due to the financial crisis, and similarly, in the first quarter of 2011, we experienced a period of high trading volume and volatility due to the natural disaster affecting Japan and the escalation of armed conflict in the Middle East. In addition, other events may affect overall market volume on a sustained basis, such as Citi’s reverse stock split in the second quarter of 2011. We may face a general decline in trading volumes, which could lower our revenues and may adversely affect our operating results if we are unable to offset such falling volumes through increased market share or matched share volume.

Regulatory changes and changes in market structure in response to the global economic crisis could have a material adverse effect on our business.

We operate in a highly regulated industry and are subject to extensive regulation. In recent years, the securities trading industry and, in particular, the securities markets have also been subject to significant regulatory changes. Moreover, in the past two years, the securities markets have been the subject of increasing governmental and public scrutiny in response to the global economic crisis. For example, on July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or Dodd-Frank, was enacted. Dodd-Frank introduces significant changes to financial industry regulation, although many of its provisions require the adoption of regulations by various federal agencies and departments. We expect Dodd-Frank to impact our business in significant ways, although until final rules have been adopted, it will be difficult to predict all of the effects Dodd-Frank may have on us. In addition, the SEC is considering various responses to the trading events

that occurred on May 6, 2010, when the U.S. stock market experienced significant volatility. It is possible that the SEC could take actions that ultimately reduce trading volumes, which could negatively affect our business. For example, on February 18, 2011, the Joint CFTC-SEC Advisory Committee on Emerging Regulatory Issues, or the Joint Advisory Committee, released recommendations regarding regulatory responses to the market events of May 6, 2010. Among other things, the Joint Advisory Committee recommended that the SEC consider whether (i) the market would benefit by changes to maker-taker pricing practices, under which a customer posting an order, or the liquidity “maker,” is paid a rebate for an execution occurring against that order, and a customer executing against an order, or the liquidity “taker,” is charged a fee, (ii) active traders, such as high-frequency traders, should be required to pay additional trading fees and (iii) to adopt requirements to give additional trading priority to displayed prices on other markets, or a “trade-at” rule.

During the next few years, there may be significant changes in the regulatory environment in which we operate our business, although we cannot predict the nature of these changes or their impact on our business at this time. For example, the SEC published a concept release on equity market structure issues in early 2010 that could result in the SEC adopting new regulations or amending existing regulations that affect our business and the businesses of our customers. The SEC’s equity market structure concept release seeks public comment regarding various issues, including co-location, high frequency trading and a potential “trade-at” rule. Co-location refers to the practice of a trading center offering market participants the opportunity to place their servers in close physical proximity to the trading center’s servers. This practice is intended to minimize network latencies between the market participant’s and the trading center’s servers. New regulations applicable to co-location could have the effect of limiting the services that we are able to offer. High frequency trading typically refers to a trading strategy that involves sending a large number of orders on a daily basis using sophisticated computer algorithms. Any new regulations that slow trading could impact high frequency trading strategies and therefore lead to a reduction in trading volumes. In addition, any new regulations that impose mandatory quoting obligations, such as a requirement to maintain quotes at or near the national best bid or offer a certain percentage of the time or limitations on the number or rate of quotation updates could increase trading risk for market participants deploying high frequency trading strategies and, hence, lead to a reduction in trading volumes. A “trade-at” rule would prohibit any trading center from executing a trade at the national best bid or offer unless the trading center was displaying that price at the time it received the incoming order. As noted above, the Joint Advisory Committee also recommended that the SEC consider adopting a “trade-at” rule. Such a rule could limit the number of orders that we are able to execute internally on BZX or BYX. Regulatory action in any of these areas could significantly impact the competitive landscape, reduce transaction volumes or limit the services that we are able to offer. The public comment period for the concept release closed on April 21, 2010. It is not possible to predict what rules the SEC will propose based on the public comments it has received.

Over the last year the SEC and other regulators have proposed various specific market structure changes. See “Regulation.” Actions on any of the specific regulatory issues currently under review in the United States and Europe could have a material impact on our business. In addition, the SEC has proposed a consolidated audit trail that would be operated by self-regulatory organizations, or SROs, such as BZX and BYX. The SEC estimated that the proposal would cost the industry approximately $4 billion in one-time implementation expenses and involve annual costs of approximately $2.1 billion. We believe our customers would bear the majority of these expenses through increased trading costs, and could result in lower transaction volumes. The SEC also has proposed a large trader reporting system. If enacted, certain market participants may seek to limit their trading to avoid registration as a large trader, which could result in lower transaction volumes for our U.S. business.

Our customers are also highly regulated. The SEC, the Financial Services Authority, or FSA, and other regulatory authorities could impose regulatory changes that could adversely impact the ability of our customers to use our markets. Regulatory changes by the SEC, the FSA or other regulatory authorities could result in the loss of a significant number of customers or a reduction in trading activity on our markets.

The European Union has issued a consultation paper on the review of MiFID and is expected to issue proposals in the spring of 2011. This effort could result in an alteration of the MiFID structure that has encouraged competition among market centers in Europe. The results of this review are uncertain, but could result in less competitive conditions or greater regulation that could increase our costs of operating in Europe.

The concept of a transaction tax also has been advocated by some in the United States and the European Union and has gained support from the European Parliament in the form of a non-binding resolution. There is a possibility that such a tax could gain support as an anti-speculation and deficit reduction measure, in which case it would likely raise trading costs and reduce transaction volumes.

In addition, Dodd-Frank will likely result in exchange trading and clearing of many swaps, which could give greater liquidity and accessibility to derivatives that compete with options traded on our U.S. listed equity options market. Furthermore, the SEC has proposed to cap transaction fees charged by options exchanges similar to the caps applied to equity exchanges. Transaction fee caps would limit the amount of fees that we can charge to access our liquidity and, accordingly, the payments we can make to attract liquidity.

Because we have a limited operating history, it is difficult to evaluate our business and prospects.

Our subsidiary BATS Trading was formed in June 2005, and live trading on our ECN began in January 2006. In addition, certain of our markets, such as our U.S. listed equity options market and BYX, only have a very short operating history. As a result, we have a limited operating history from which you can evaluate our business and our prospects. We will encounter risks and difficulties frequently experienced by early-stage companies in rapidly evolving industries such as ours. These risks and difficulties include, but are not limited to, our ability to:

•

attract and retain customers;

•

expand and enhance reliable and cost-effective product and service offerings to customers;

•

respond effectively to competitive pressures;

•

diversify our sources of revenues;

•

respond to regulatory changes or demands;

•

maintain adequate control of our expenses;

•

operate, support, expand and develop our operations, website, software, communications and other systems;

•

manage growth in personnel and operations; and

•

increase awareness of our brand or market positioning.

If we are unsuccessful in addressing these risks or in executing our business strategy, our business, financial condition and results of operations may suffer.

We are dependent on the members of our senior management team and other key personnel.

We are highly dependent upon our Chairman, President and Chief Executive Officer, Joe Ratterman. Mr. Ratterman’s talents and leadership have been, and continue to be, critical to our success. The diminution or loss of the services of Mr. Ratterman for any reason, and any negative market or industry perception arising from that diminution or loss, would have a material adverse effect on our business.

Our success also depends largely on the efforts and abilities of the other key members of our senior management team. Many of these individuals have worked together closely since our inception in 2005. Members of our senior management team are employees at will. Accordingly, it is possible that one or more members of our senior management team could resign to work elsewhere. Because each member of our senior management team has a different area of specialization, the departure of any one of these individuals could create a deficiency in one of the core aspects of our business, particularly given our small number of employees relative to our competitors.

We are also dependent on the efforts of our team of technology professionals, many of whom have been with us for several years, and on our ability to recruit and retain highly skilled and often specialized personnel, particularly in light of the rapid pace of technological advances. The level of competition in our industry for individuals with this level of experience or these skills is intense. Significant losses of key personnel, particularly to competitors, could make it difficult for us to compete successfully. In addition, we may be unable to attract and retain qualified management and personnel in the future, including in relation to any diversification of our product and service offerings into new asset classes and/or new geographic locations.

We do not maintain “key person” life insurance policies on any of our executive officers, managers, key employees or technical personnel. The loss of the services of these persons for any reason, as well as any negative market or industry perception arising from those losses, could have a material adverse effect on our business, financial condition and operating results.

We may not be able to keep up with rapid technological and other competitive changes affecting our industry, and we may be unable to further diversify our business.

The markets in which we compete are characterized by rapidly changing technology, evolving industry standards and regulations, frequent enhancements to existing products and services, the adoption of new services and products and changing customer demands. If our platform fails to function as expected, our business would be negatively affected. In addition, our business, financial condition and operating results may be adversely affected if we cannot successfully develop, introduce or market new services and products or if we need to adopt costly and customized technology for our services and products. Further, our failure to anticipate or respond adequately to changes in technology and customer preferences or any significant delays in product development efforts could have a material adverse effect on our business, financial condition and operating results.

In addition, we will face significant challenges as we seek to diversify our product and service offerings. We may, for example, diversify our business by competing with NYSE Euronext, NASDAQ OMX, Direct Edge and other exchanges for new asset classes and in new geographic locations and new or existing listings. We will face substantial competition from these market centers, some of which have greater brand recognition than we do and offer a broader range of services than we currently offer. Accordingly, we may not be able to increase our revenues or compete successfully by further diversifying our product and service offerings.

We generate a significant percentage of our total revenues from, and are provided with significant liquidity in our markets by, customers who are affiliates of our strategic investors, who are not contractually obligated to continue to use our services or purchase our products and who also use the services of our competitors.

We earn a significant percentage of our revenue from customers who are affiliates of our strategic investors. For the six months ended June 30, 2011 and 2010, 29.8% and 32.0% of our total revenues were generated by affiliates of our strategic investors, respectively. For the years 2010, 2009 and 2008, 31.7%, 29.8% and 22.8% of our total revenues, respectively, were generated by affiliates of our strategic investors. In addition, affiliates of our strategic investors also provide us with liquidity for which we provide them with a rebate. In particular, for the six months ended June 30, 2011 and 2010, an affiliate of one of our strategic investors accounted for 40.0% and 51.7%, respectively, of total liquidity rebates paid, and for the years 2010, 2009 and 2008, an affiliate of one of our strategic investors accounted for 31.0%, 51.0% and 51.4%, respectively, of total liquidity rebates paid. None of our customers is contractually or otherwise obligated to continue to use our services or purchase our products. In addition, affiliates of our strategic investors and our other customers have made, and may continue to make, investments in businesses that directly compete with us. Our customers also trade, and will continue to trade, on markets operated by our competitors. The loss of, or a significant reduction in, participation on our markets by these customers may have a material adverse effect on our business, financial condition and results of operations.

We may not be able to successfully integrate Chi-X Europe, which may result in an inability to realize the anticipated benefits of the Chi-X Europe acquisition, and certain of our and Chi-X Europe’s historic customers may seek to diversify their order flow by directing their orders to other trading venues following our acquisition, which may result in lower market share than would otherwise be implied by combing historical volume numbers.

Rationalizing and coordinating our and Chi-X Europe’s operations will involve complex technological, operational and personnel-related challenges. This process will be time-consuming and expensive and may disrupt the business of the combined company. Difficulties, costs and delays could be encountered with respect to:

•

obtaining the requisite regulatory approval to complete the acquisition;

•

combining the companies’ operations and systems, which could lead to the combined company not achieving the synergies we anticipate;

•

resolving possible inconsistencies in standards, controls, procedures and policies, business cultures and compensation structures between us and Chi-X Europe;

•

the diversion of management’s attention from ongoing business concerns and other strategic opportunities;

•

the retention of our and Chi-X Europe’s key employees and management;

•

the implementation of disclosure controls, internal controls and financial reporting systems at Chi-X Europe to enable the combined company to comply with the requirements of U.S. GAAP and U.S. securities laws and regulations required as a result of the combined company’s status as a reporting company under the Exchange Act;

•

the coordination of geographically separate organizations;

•

possible tax costs or inefficiencies associated with integrating the operations of the combined company;

•

possible modification of Chi-X Europe’s operating control standards in order for the combined company to comply with the Sarbanes-Oxley Act and the rules and regulations promulgated thereunder, which is required as a result of the combined company’s status as a reporting company under the Exchange Act; and

•

the retention of strategic partners and attraction of new strategic partners.

For these reasons, the combined company may not achieve the anticipated financial and strategic benefits, including cost savings from operational efficiencies and synergies, from the combination of our and Chi-X Europe’s businesses, and any actual cost savings and synergies may be lower than we currently expect and may take a longer time to achieve than we currently anticipate. In addition, we may fail to realize any of the anticipated benefits of the combination of the two companies.

In addition, upon our acquisition of Chi-X Europe, certain of our and Chi-X Europe’s historic customers may seek to diversify their order flow by directing their orders to other trading venues, resulting in lower transaction revenues on a combined basis than we and Chi-X Europe might have generated as separate companies. As a result, our combined volume on a historical basis should not be viewed as indicative of our combined volume following the acquisition.

We may have difficulty executing our growth strategy and managing our growth effectively.

We have experienced significant growth in our business since our inception in 2005 and our transition from operating an ECN, to operating national securities exchanges and an MTF. While our market share has increased, there is no guarantee this will continue in the future. Continuing to grow our business will require increased investment in our facilities, personnel and financial and management systems and controls. Unless our growth

results in an increase in our revenues that is proportionate to the increase in our costs associated with this growth, our future profitability will be adversely affected. Furthermore, failure to successfully diversify into new asset classes or new geographies may adversely affect our growth strategy and our future profitability.

As part of our growth strategy, we intend to continue evaluating potential acquisition opportunities and strategic alliances. Any such transaction may be effected quickly, may occur at any time and may be significant in size relative to our existing assets and operations. The market for acquisition targets and strategic alliances is highly competitive, particularly in light of increasing consolidation in the securities trading industry, which may adversely affect our ability to find acquisition candidates or strategic partners that fit our growth strategy and our investment parameters. These transactions involve numerous risks, including, among others:

•

failure to achieve financial or operating objectives;

•

failure to successfully and timely integrate any operations, products, services or technology we may acquire or combine with in a strategic alliance;

•

diversion of management’s and other key personnel’s attention;

•

failure to obtain necessary regulatory or other approvals;

•

potential loss of customers or personnel; or

•

failure to obtain necessary financing on acceptable terms.

Failure to successfully manage any acquisition or strategic alliance we may make in the future could adversely affect our growth strategy and our future profitability. Furthermore, future acquisitions or strategic alliances may require significant resources and may result in significant unanticipated losses, costs or liabilities.

These transactions may also result in our recording additional goodwill and other intangible assets that are susceptible to valuation adjustments as a result of changes in various factors or conditions. For example, following our pending acquisition of Chi-X Europe, we expect to record approximately $248.5 million of goodwill and other intangible assets. We assess the potential impairment of goodwill at least annually, or more frequently when events or changes in circumstances signal indicators of impairment are present. Adverse changes in economic conditions or our operations could affect the assumptions we use to calculate the fair value, which in turn could result in an impairment charge in future periods that would impact our results of operations and financial position.

The regulatory framework under which we operate and new regulatory requirements or new interpretations of existing regulatory requirements could require substantial time and resources for compliance, which could make it difficult and costly for us to operate our business.

We operate in a highly regulated industry and may be subject to regulatory actions or other legal proceedings that could lead to censures, fines or other penalties if we fail to comply with our legal and regulatory obligations. Under current U.S. federal securities laws, changes in the rules and operations of our markets, including our pricing structure, must be reviewed and in many cases explicitly approved by the SEC. The SEC may approve, disapprove or recommend changes to proposals that we submit. In addition, the SEC may delay either the approval process or the initiation of the public comment process. Any delay in approving changes, or the altering of any proposed change, could have an adverse effect on our business, financial condition and operating results. Moreover, the rule filing process has recently been altered by financial regulatory reform legislation. While the changes appear to reduce the inherent time delays for approval of rule changes by exchanges, the details of these changes are not fully known at this time. In addition, we must compete with ATSs that are not subject to the same SEC approval process for changes in rules and operations, including pricing.

Our European business is subject to regulatory oversight in the United Kingdom by the FSA, which through the “passporting” process provides authorization to carry on business in other EEA member states. The authorities may revoke this authorization if we do not suitably carry out our regulated business activities. The

authorities are also entitled to request that we adopt measures in order to ensure that we continue to fulfill the authorities’ requirements. Any failure by us to meet these requirements or any revocation by the authorities of our authorization to carry on business in other EEA member states would materially affect our ability to operate a trading venue on a pan-European basis and could adversely affect our business, financial condition and results of operations.

We have self-regulatory obligations that may create conflicts of interests.

We have obligations to regulate and monitor activities in our markets and ensure compliance with applicable law and the rules of our markets by market participants. In the United States, the SEC has previously expressed concern about potential conflicts of interest of “for-profit” exchanges performing the role of an SRO that must oversee and surveil members of the exchange that are also crucial to the exchange’s economic success. For example, we are responsible for identifying possible violations of the securities laws by our members and taking regulatory action against those members if such violations are confirmed. We could be conflicted in pursuing such regulatory actions against our customers because to do so could result in a loss of trading volumes on our markets. Any failure by us to diligently and fairly regulate our markets or to otherwise fulfill our regulatory obligations could significantly harm our reputation, prompt SEC scrutiny and adversely affect our business.

We depend on third-party service providers for certain services that are important to our business. An interruption or cessation of such service by any third party could have a material adverse effect on our business.

We depend on a number of service providers, including but not limited to banking and clearing organizations such as the National Securities Clearing Corporation, or NSCC, and The Options Clearing Corporation, or OCC, and its member clearing firms; the European Multilateral Clearing Facility N.V., or EMCF; data center providers such as Savvis, Inc., which hosts our primary data center in the United States; the Consolidated Tape Association and the Options Price Reporting Authority, LLC, or OPRA; and various vendors of communications and networking products and services.

We also rely on certain third-party broker-dealers for routing services in certain circumstances. Specifically, we may route an order from a customer away from BZX or BYX to another trading venue if there is insufficient liquidity on BZX or BYX to match the order and/or if the customer is utilizing one of our smart-order routing strategies. All orders routed away from BZX and BYX are sent to BATS Trading for routing. BATS Trading, in turn, may use a third-party broker-dealer to establish backup connectivity to another exchange in the event that BATS Trading’s connection to such exchange fails, because BATS Trading does not have a direct connection to such exchange or to take advantage of tiered pricing rates at such exchange. We rely on Bank of America Merrill Lynch, Citi and affiliates of Citi, Morgan Stanley and Credit Suisse, each of which is an affiliate of one of our strategic investors, to route orders that are not routed directly by BATS Trading. Once BATS Trading (or such third-party broker-dealer) fills an order on another market, it sends the executed trade to a clearing broker to match the details of the trade with the clearing broker for the other party to the trade. We rely on Wedbush Securities, an affiliate of one of our strategic investors, as a member of NSCC, to clear trades in listed cash equity securities routed by us to other markets; and we rely on Bank of America Merrill Lynch, as a clearing member of the OCC, to clear trades in U.S. listed equity options that we route to other markets. On the settlement date of the trade, our clearing broker will deliver or receive the matched amount of securities or funds to settle the trade with the other party to the trade.

We cannot assure you that any of these providers will be able to continue to provide these services in an efficient manner or that they will be able to adequately expand their services to meet our needs. An interruption or malfunction in or the cessation of an important service by any third party and our inability to make alternative arrangements in a timely manner, or at all, could have a material adverse impact on our business, financial condition and operating results. In addition, we currently rely on the Financial Industry Regulatory Authority, or

FINRA, to perform certain regulatory functions on our behalf pursuant to a regulatory services agreement, or RSA, which terminates in 2011. We recently executed an RSA with CBOE, and during 2011, we will begin relying on CBOE to perform the regulatory functions that are currently performed by FINRA. Under both RSAs, we maintain ultimate responsibility for the regulatory activities.

Financial or other problems experienced by third parties could have an adverse effect on our business.

We are exposed to credit risk from third parties, including customers, clearing agents and counterparties. For example, we are exposed to credit risk for transaction fees we bill to customers on a monthly basis in arrears. Our customers and other third parties may default on their obligations to us due to lack of liquidity, operational failure, bankruptcy or other reasons.

In addition, with respect to orders BATS Trading routes to other markets for execution on behalf of our customers, BATS Trading is exposed to some counterparty credit risk in the case of a failure on the part of our clearing firm, Wedbush Securities. Wedbush Securities guarantees trades until one day after the trade date, after which time NSCC provides a guarantee. Thus, BATS Trading is potentially exposed to credit risk to the counterparty to a trade routed to another market center between the trade date and one day after the trade date in the event that Wedbush Securities fails. Similarly, with respect to orders in U.S. listed equity options, we route orders for execution to other national securities exchanges through either BATS Trading or through affiliates of Bank of America Merrill Lynch and Citi, as discussed above. For orders in U.S. listed equity options routed through Bank of America Merrill Lynch or Citi and executed on another national securities exchange, BATS Trading has counterparty credit risk exposure to Bank of America Merrill Lynch or Citi until a trade settles (generally one day after the trade date). For orders in U.S. listed equity options routed directly by BATS Trading to, and executed on, another national securities exchange, BATS Trading also has counterparty credit exposure to Bank of America Merrill Lynch, which acts as BATS Trading’s options clearing firm on such transactions.

Our exposure to credit risk may be further impacted by volatile securities markets that may affect the ability of our customers and other third parties to satisfy their contractual obligations to us. Moreover, we may not be successful in managing our credit risk through reporting and control procedures or by maintaining credit standards. Any losses arising from such defaults or other credit losses could adversely affect our financial condition and operating results.

We may be required to assume ownership of a position in securities in connection with our order routing service, which could subject us to trading losses when we dispose of that position.

We offer a smart-order routing service through our broker-dealer subsidiary, BATS Trading, which provides our customers with access to other market centers when we route their orders to those market centers for execution. In connection with this service, however, we may assume ownership of a position in securities. This may occur, for example, when a market center to which we have routed a customer’s order experiences systems problems and is unable to determine the status of that order. When this happens, we may make a business decision to provide a cancellation notice to our customer, relieving our customer of any liability with respect to the order. We may be informed later, however, that the order was executed at the market center to which we routed it, in which case BATS Trading would be required to take ownership of that securities position. Our clearing broker, Wedbush Securities, maintains an error account on behalf of BATS Trading into which such positions settle, and we require Wedbush Securities to trade out of those positions as expeditiously as possible, which could result in our incurring trading losses.

Current economic conditions could adversely affect our business and financial condition.

Our business performance is impacted by a number of factors, including general economic conditions and other factors that are generally beyond our control. Although market conditions have improved recently, a long-term continuation of challenging economic conditions is likely to negatively impact our business. Poor economic conditions may result in a decline in trading volume and a reduction in the demand for our products and could affect the ability of our customers to meet their obligations to us.

Trading volume is directly affected by economic, political and market conditions, broad trends in business and finance, unforeseen market closures or other disruptions in trading, the level and volatility of interest rates, inflation, changes in price levels of securities and the overall level of investor confidence. In recent years, trading volumes across our markets have fluctuated significantly depending on market conditions and other factors beyond our control. In addition, trading volume in a particular stock could be negatively impacted by a significant reverse stock split which materially reduces the number of shares of such stock in the market. It is not possible to accurately forecast volatility or trading volumes. Because a significant percentage of our revenue is tied directly to the volume of securities traded on our markets, it is possible that a general decline in trading volumes could lower revenues and may adversely affect our operating results if we are unable to offset falling volumes through increased market share. In particular, volume for our U.S. Equities segment decreased in 2010 from 2009 as a result of the uncertain economic climate, reduced volumes and decreased volatility.

In Europe, countries such as Portugal, Ireland, Greece and Spain have been particularly affected by the recent financial and economic conditions. The European Union, the European Central Bank and the International Monetary Fund have prepared rescue packages for some of the affected countries. We cannot predict with any certainty whether these packages or other rescue plans will be successful or the effect that they may have on our business, results of operations, cash flows and financial condition.

Fluctuations in our quarterly operating results may negatively affect the market price of our Class A common stock.

Our business experiences seasonal fluctuations, reflecting reduced trading activity generally during the third quarter of each year and during the last month of the year. In addition, the financial services industry is risky and unpredictable and is directly affected by many national and international factors beyond our control, including:

•

economic, political and geopolitical market conditions;

•

natural disasters, terrorism, war or other catastrophes;

•

broad trends in industry and finance;

•

changes in price levels and volatility in the stock markets;

•

the level and volatility of interest rates;

•

changes in government monetary or tax policy;

•

other legislative and regulatory changes;

•

the perceived attractiveness of the U.S. or European capital markets; and

•

inflation.

Any one of these factors could have a material adverse effect on our business, financial condition and operating results by causing a substantial decline in the financial services markets and reducing trading volumes. As a result, it is possible that our operating results or other operating metrics may fail to meet the expectations of stock market analysts and investors. If this happens, the market price of our Class A common stock may be adversely affected.

System limitations, failures or security breaches could harm our business.

Our business depends on the integrity and performance of our computer and communications systems. If our systems cannot expand to cope with increased demand or otherwise fail to perform, we could experience unanticipated disruptions in service, slower response times and delays in the introduction of new products and services. These consequences could result in trading outages, lower trading volumes, financial losses, decreased customer service and satisfaction and regulatory sanctions. Our markets have experienced occasional systems failures and delays in the past and could experience future systems failures and delays.

Our systems and operations also are vulnerable to damage or interruption from human error, natural disasters, power loss, sabotage or terrorism, computer viruses, unauthorized access, intentional acts of vandalism and similar events. Persons who circumvent security measures could wrongfully access and use our information or our customers’ information or cause interruptions or malfunctions in our operations. Although we currently maintain and expect to maintain security measures designed to protect the integrity of our systems, multiple computer facilities designed to provide redundancy and back-up to reduce the risk of system disruptions and facilities expected to maintain service during a system disruption, such security measures, systems and facilities may prove inadequate. Any breach in security or system failure that allows unauthorized access, causes an interruption in service or decreases the responsiveness of our systems could impair our reputation, damage our brand name and negatively impact our business, financial condition and operating results.

The occurrence or perception of unauthorized disclosure of confidential information could harm our business.

In the course of our business, we receive, process, transmit and store confidential information. Our treatment of such information is subject to contractual restrictions. While we take measures to protect against unauthorized access to such information, these measures may be inadequate, and any failure on our part to protect this information may subject us to contractual liability and damages, loss of business, penalties and unfavorable publicity. Even the mere perception of a security breach or inadvertent disclosure of confidential information could harm our reputation. The occurrence of any of these events could have an adverse effect on our business.

Our inability to protect our intellectual property rights and claims by others that we infringe their intellectual property rights could adversely affect our business.

To protect our intellectual property rights, we rely on a combination of trademark and copyright laws in the United States and similar laws in other countries, trade secret protection, confidentiality agreements and other contractual arrangements with our employees, customers and others. Despite these measures, any of our intellectual property rights could be challenged, invalidated, circumvented or misappropriated, and any application for registration of such rights could be denied. We may be unable to detect the unauthorized use of our proprietary information or take appropriate steps to enforce our intellectual property rights. Failure to protect our intellectual property adequately could harm our brand and affect our ability to compete effectively. Defending our intellectual property rights could result in the expenditure of significant financial and managerial resources, which could adversely affect our business, financial condition and operating results. Further, the laws of certain countries do not protect intellectual property rights to the same extent as the laws of the United States. Therefore, in certain jurisdictions, we may be unable to protect our intellectual property and proprietary technology adequately against unauthorized third-party copying or use, which could adversely affect our competitive position.

Although we have filed two patent applications in the United States, we do not anticipate relying upon patents as a primary means of protecting our rights in our intellectual property. In any event, there can be no assurance that our patent applications will be approved, that any issued patents will adequately protect our intellectual property, or that such patents will not be challenged by third parties.

Finally, third parties may claim that we or customers indemnified by us are infringing upon their intellectual property rights. Even if we believe that such claims are without merit, they can be time-consuming and costly to defend and divert management resources and attention. Successful claims of intellectual property infringement also might require us to redesign infringing technology, enter into costly settlement or license agreements, pay costly damage awards or face a temporary or permanent injunction prohibiting us from using infringing technology. If we are found to be infringing and cannot, or do not, license the infringed technology on reasonable pricing terms or at all, or substitute similar technology from another source, our business, financial condition and results of operations could be adversely impacted.

We are currently a defendant in a patent infringement action brought by Realtime Data, LLC d/b/a IXO, which we refer to as Realtime. Realtime alleged in three complaints that we, along with certain other financial instrument exchanges, investment and commercial banking companies and financial data providers, infringed six Realtime patents by using, selling or offering for sale financial data compression products or services. The complaint seeks declaratory and injunctive relief or, in the alternative, a compulsory ongoing licensing fee, as well as unspecified damages for past and future infringement, attorneys’ fees, costs and expenses. Further, several of the defendant financial data providers are our members whom we have indemnified against any damages resulting from this action. While we believe the claims against us and such members are without merit and intend to vigorously defend this litigation, there can be no assurance that we will be successful, and any adverse outcome could adversely affect our business.

Our use of open source software code may subject our software to general release or require us to re-engineer our software, which could harm our business.

We have used open source software code to create our proprietary software for use in our business. Companies that incorporate open source software into their products have, from time to time, faced claims challenging the ownership of open source software. As a result, we could be subject to suits by parties claiming ownership of what we believe to be open source software. In addition, some open source software licenses require users who distribute open source software as part of their software to publicly disclose all or part of the source code in their software and make any derivative works of the open source code available on unfavorable terms or at no cost. Open source license terms may be ambiguous, and many of the risks associated with usage of open source software cannot be eliminated. We believe that our use of open source software is in compliance with the relevant open source software licenses and does not require disclosure of any of our source code. However, if we were found to have inappropriately used open source software, we may be required to release our proprietary source code, re-engineer or discontinue use of our software or take other remedial action.

We are subject to risks relating to litigation, potential securities law liability and other liability.

Many aspects of our business potentially involve substantial liability risks. SROs such as BZX and BYX are required by federal law to perform a variety of functions that would otherwise be performed by a governmental agency. As such, and similar to sovereign immunity accorded to governments, U.S. federal courts have held that SROs are immune from civil damages for conduct undertaken as part of their statutorily delegated adjudicatory, regulatory and prosecutorial authority. This immunity, however, only covers certain of our activities in the United States, and we could be exposed to liability under national and local laws, court decisions and rules and regulations promulgated by regulatory agencies. Furthermore, in the United States, we are subject to oversight by the SEC. In the case of non-compliance with our obligations under the securities laws, we could be subject to investigation and judicial or administrative proceedings that may result in substantial penalties. Any such liability or penalties could have a material adverse effect on our business.

Our European business is subject to regulatory oversight in the United Kingdom by the FSA, which through the “passporting” process provides authorization to carry on business in other EEA member states. In addition, our operations are regulated at the European Union level. If a regulatory authority makes a finding of non-compliance, conditional fines could be imposed and our licenses could be revoked. Any such fine or revocation of a license could have a material adverse effect on our business.

Failures in our compliance systems could subject us to significant legal and regulatory costs. Furthermore, if our risk management methods are not effective, our business, reputation and financial results may be adversely affected.

Our ability to comply with all applicable laws and rules is largely dependent on our establishment and maintenance of compliance, audit and reporting systems and procedures, as well as our ability to attract and retain qualified compliance, audit and risk management personnel. These systems and procedures may not be fully effective. We face the risk of intervention by regulatory authorities, including extensive examination and surveillance activity. In the case of actual or alleged non-compliance with regulations, we could be subject to

investigations and judicial or administrative proceedings that may result in substantial penalties or civil lawsuits for damages, which can be substantial. In the past, the SEC has brought actions against exchange operators for failing to fulfill their obligations to have an effective regulatory system. Any failure to comply with applicable laws and rules could adversely affect our business, reputation, financial condition and operating results and, in extreme cases, our ability to conduct our business or portions thereof.

Additionally, we have adopted policies and procedures to identify, monitor and manage our risks. These policies and procedures, however, may not be fully effective. If our policies and procedures are not fully effective or we are not always successful in monitoring or evaluating the risks to which we are or may be exposed, our business, reputation, financial condition and operating results could be materially adversely affected.

In 2009, we identified a material weakness in our internal control over financial reporting which has now been remediated. Our business may be adversely affected if we fail to maintain effective controls over financial reporting in the future.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. GAAP.

In 2009, we identified material weaknesses in internal controls related to financial reporting and accounting for stock compensation. Remediation efforts to enhance our internal controls related to financial reporting and accounting for stock compensation have been completed. We have restated our 2009 consolidated financial statements, and the controls we implemented to address the material weaknesses were determined to be effective by our management as of December 31, 2010. We face the risk, however, that, notwithstanding our efforts to identify and remedy the material weakness in our internal control over financial reporting, we may discover other material weaknesses in the future. Failure to maintain an effective internal control environment could result in our not being able to accurately report our financial results, prevent or detect fraud or provide timely and reliable financial information pursuant to the reporting obligations we will have as a public company, which could have a material adverse effect on our business, financial condition and results of operations. Further, it could cause our investors to lose confidence in the financial information we report, which could adversely affect the price of our Class A common stock.

Damage to our reputation could have a material adverse effect on our business.

We believe one of our competitive strengths is our strong reputation. Various issues may give rise to reputational risk, including issues relating to:

•

the representation of our business in the media;

•

the quality of our products, including the reliability of our transaction-based business, and the accuracy of our market data;

•

the ability to execute our business plan, key initiatives or new business ventures and the ability to keep up with changing customer demands;

•

the accuracy of our financial statements and other financial and statistical information;

•

the quality of our corporate governance structure;

•

the quality of our disclosure controls or internal controls over financial reporting, including any failures in supervision;

•

security breaches, including any unauthorized delivery of proprietary data to third parties;

•

management of our outsourcing relationships, including our relationships with CBOE and FINRA; and

•

any misconduct or fraudulent activity by our employees or other persons formerly or currently associated with us.

Damage to our reputation could cause a reduction in the trading volume on our exchanges or cause us to lose customers. This, in turn, may have a material adverse effect on our business, financial condition and operating results.

Because we have operations in Europe, we are exposed to currency risk.

We have operations in the United States, the United Kingdom and continental Europe, and with our pending acquisition of Chi-X Europe, we will significantly increase our presence in Europe. We therefore have significant exposure to exchange rate movements between the British pound, the Euro and the U.S. dollar, and upon the completion of the Chi-X Europe acquisition, this currency risk exposure is expected to increase. Significant inflation or changes in foreign exchange rates with respect to one or more of these currencies could occur as a result of general economic conditions, acts of war or terrorism, changes in governmental monetary or tax policy or changes in local interest rates. These exchange rate differences will affect the translation of our non-U.S. results of operations and financial condition into U.S. dollars as part of our consolidated financial statements.

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain qualified board members.

As a public company, we will be subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act of 2002, which we refer to as the Sarbanes-Oxley Act, and BZX listing requirements. The requirements of these rules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and may also place undue strain on our systems and resources. The Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and financial condition. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal controls for financial reporting. Our management will be required to report on the effectiveness of our internal control over financial reporting and our independent registered public accounting firm will be required to attest to such internal control over financial reporting. In order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, significant resources and management oversight will be required. As a result, management’s attention may be diverted from other business concerns, which could have a material adverse effect on our business, financial condition and results of operations.

These rules and regulations could also make it more difficult for us to attract and retain qualified independent members of our board of directors. Additionally, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance. We may be required to accept reduced coverage or incur substantially higher costs to obtain coverage.

Risks Relating to an Investment in Our Class A Common Stock

Volatility in our stock price could adversely affect your investment in our Class A common stock.

There has not been a public market for our Class A common stock prior to this offering. We cannot predict the extent to which a trading market for our Class A common stock will develop or how liquid that market might become. If you purchase shares of Class A common stock in this offering, you will pay a price that was not established in the public trading markets. The initial public offering price will be determined by negotiations between us, the underwriters and the selling stockholders. You may not be able to resell your shares above the initial public offering price and may suffer a loss on your investment.

Broad market and industry factors may adversely affect the market price of our Class A common stock, regardless of our actual operating performance. Factors that could cause fluctuations in our stock price may include, among other things:

•

actual or anticipated variations in quarterly operating results;

•

changes in financial estimates by us or by any securities analysts who might cover our stock;

•

conditions or trends in our industry, including trading volumes, regulatory changes or changes in the securities marketplace;

•

changes in the market valuations of other companies operating in our industry;

•

announcements by us or our competitors of significant acquisitions, strategic partnerships or divestitures;

•

announcements of investigations or regulatory scrutiny of our operations or lawsuits filed against us;

•

additions or departures of key personnel; and

•

sales of our Class A common stock, including sales of our Class A common stock by our directors and officers, our strategic investors or the estate of Lehman Brothers Holdings Inc., including upon conversion of any Class B common stock, Non-Voting Class A common stock or Non-Voting Class B common stock following the expiration of the applicable transfer restrictions or the occurrence of other limited circumstances.

We will be controlled by our strategic investors, whose interests may differ from those of other stockholders.

Upon completion of this offering, our strategic investors will collectively own approximately shares of our Class A common stock and shares of Class B common stock, representing approximately % of the total voting power of our outstanding capital stock. See “Principal and Selling Stockholders.” We are not a party to any voting agreement with any of our stockholders, other than the Investor Rights Agreement dated as of May 13, 2010 among us and our stockholders (which, pursuant to its terms, will terminate upon consummation of this offering except for the registration rights contained therein), which we refer to as the Investor Rights Agreement, and we are not aware of any other voting agreements among our strategic investors; however, they may enter into voting agreements in the future or otherwise vote in a similar manner. To the extent that all of these strategic investors vote similarly, they will be able, by virtue of their ability to elect our board of directors, to control our policies and operations, including the determination of our strategic plans, appointment of management, future issuances of our common stock or other securities, the payments of dividends on our common stock, entering into extraordinary transactions and the approval of major financing decisions, and their interests may not in all cases be aligned with your interests. This concentrated control will limit your ability to influence corporate matters. As a result, the market price of our Class A common stock could be adversely affected.

Affiliates of our strategic investors are also significant customers. See “Certain Relationships and Related Transactions.” As a result, the interests of these investors could conflict with your interests as holders of our Class A common stock in a number of ways. For example:

•

you may disagree with the structure and timing of future transfers by these stockholders of all or any portion of their ownership interests in us. The actual or potential sale by these stockholders of their holdings of our Class A common stock either directly or upon conversion of Non-Voting Class A common stock, Class B common stock or Non-Voting Class B common stock held by them could cause the market price of our stock to decline significantly;

•

these stockholders may have or acquire an ownership interest in competing businesses (including national securities exchanges, MTFs or ECNs) and they may make decisions that favor the competing enterprise over our company; and

•

many of these stockholders, as affiliates of our customers, have an incentive to favor commercial terms that may not be advantageous to us, such as lower “taker fees” and higher “maker” rebates on BZX.

Accordingly, our strategic investors may have different business objectives, any of which could adversely impact the market value of your shares of Class A common stock.

Certain affiliates of the underwriters of this offering are also selling stockholders and, therefore, have interests in this offering beyond customary underwriting discounts and commissions.

Certain affiliates of the underwriters of this offering are participating as selling stockholders in this offering. There may be a conflict of interest between their interests as selling stockholders (for example, to maximize the value of their investment) and their respective interests as underwriters (for example, in negotiating the initial public offering price) as well as your interest as a purchaser. As participants in this offering that are seeking to realize the value of their investment in us, these underwriters have interests beyond customary underwriting discounts and commissions.

If securities or industry analysts do not publish research or reports about us, or if they adversely change their recommendations regarding our Class A common stock, then our stock price and trading volume could decline.

The trading market for our Class A common stock will be influenced by the research and reports that industry or securities analysts publish about us, our industry and our markets. If no analyst elects to cover us and publish research or reports about us, the market for our Class A common stock could be severely limited, and our stock price could be adversely affected. In addition, if one or more analysts ceases coverage of us or fails to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. If one or more analysts who elect to cover us adversely changes their recommendations regarding our Class A common stock, our stock price could decline. In addition, SEC rules may make it impractical for analysts associated with some of our strategic investors to cover us.

Our share price may decline due to the large number of shares eligible for future sale.

Sales of substantial amounts of our Class A common stock, or the possibility of such sales, may adversely affect the market price of our Class A common stock. These sales may also make it more difficult for us to raise capital through the issuance of equity securities at a time and at a price we deem appropriate. See “Shares Eligible for Future Sale” for a discussion of possible future sales of Class A common stock.

Upon completion of this offering, there will be shares of Class A common stock, shares of Non-Voting Class A common stock, shares of Class B common stock and shares of Non-Voting Class B common stock outstanding. Each share of Class B common stock and Non-Voting Class B common stock will automatically convert into one share of Class A common stock in connection with any transfer, whether or not for value, following the expiration of the three-year restriction on transfer, except for certain transfers described in “Description of Capital Stock—Common Stock—Conversion.” Each share of Non-Voting Class A common stock will automatically convert into one share of Class A common stock in connection with any transfer to anyone other than a “related person” (as defined under “Description of Capital Stock—Ownership and Voting Limits on Our Common Stock”) of the holder, whether or not for value, following the expiration of the 180-day or one-year restriction on transfer. Of these shares, will be freely transferable without restriction or further registration under the Securities Act of 1933, as amended, which we refer to as the Securities Act, after one year. See “Shares Eligible for Future Sale.”

In addition to outstanding shares eligible for sale, approximately million shares of our Class A common stock will be issuable upon consummation of this offering under currently outstanding stock options granted to several executive officers and employees under our incentive plans. Such shares of Class A common stock will also be subject to a transfer restriction that expires one year from the completion of this offering.

Additionally, the Investor Rights Agreement provides for certain registration rights, including demand registration rights. For a more detailed description of these registration rights, see “Description of Capital Stock—Registration Rights.”

Upon completion of this offering, our strategic investors will collectively own approximately shares of our class A common stock and shares of Class B common stock, representing approximately % of the total voting power of our outstanding capital stock. See “Principal and Selling Stockholders.”

Your ownership of our company may be diluted if additional capital stock is issued to raise capital, to finance acquisitions, in connection with strategic transactions or pursuant to stock options or other equity compensation awards.

We may seek to raise additional funds, finance acquisitions or develop strategic relationships by issuing equity or convertible debt securities, which would reduce the percentage ownership of existing stockholders. In addition, as of June 30, 2011, shares of Class A common stock were issuable upon the exercise of outstanding stock options, and an aggregate of shares of Class A common stock were reserved for future issuance under our stock option plans. Following this offering, our board of directors will have the authority, without action or vote of the stockholders, to issue all or any part of our authorized but unissued shares of preferred stock or Class A common stock (except shares of Class A common stock reserved for issuance upon conversion of our Non-Voting Class A common stock, Class B common stock or Non-Voting Class B common stock), including pursuant to stock options or other equity compensation awards. Following our reclassification and -for- stock split, shares of preferred stock and shares of Class A common stock will be authorized and unissued under our amended and restated certificate of incorporation. Future issuances of preferred stock or Class A common stock would reduce your influence over matters on which stockholders vote and would be dilutive to earnings per share. In addition, any newly issued preferred stock could have rights, preferences and privileges senior to those of our common stock. Those rights, preferences and privileges could include, among other things, the establishment of dividends that must be paid prior to declaring or paying dividends or other distributions to holders of our common stock, greater or preferential liquidation rights, which could negatively affect the rights of holders of our common stock and the right to convert such preferred stock into shares of our Class A common stock at a rate or price which would have a dilutive effect on the outstanding shares of our common stock.

Provisions in our amended and restated certificate of incorporation and bylaws and Delaware law might discourage, delay or prevent a change of control of our company or changes in our management and, therefore, depress the trading price of our Class A common stock.

Pending approval by the SEC of amendments to our certificate of incorporation and bylaws pursuant to the rule filing process under Section 19(b) of the Exchange Act, our organizational documents will contain provisions that may have the effect of discouraging or delaying a change in control of us or unsolicited acquisition proposals that a stockholder might consider favorable. These provisions generally include:

•

the dual class common stock structure of our voting stock. As a result of this structure our strategic investors have significant influence over all matters requiring stockholder approval, including the election of directors and significant corporate transactions, such as a merger or other sale of our company or its assets. This concentrated control could discourage others from initiating any potential merger, takeover or other change of control transaction that other stockholders may view as beneficial;

•

voting and ownership limitations. Our amended and restated certificate of incorporation prohibits any person from owning greater than 40% of any class of our capital stock, prohibits exchange members from owning greater than 20% of any class of our capital stock and prohibits all persons from exercising a greater than 20% voting power of our issued and outstanding capital stock, in each case subject to certain conditions and exceptions;

•

advance notice requirements for stockholder proposals and director nominations;

•

the inability of stockholders to call special meetings;

•

the ability of our board of directors to make, alter or repeal our bylaws; and

•

the ability of our board of directors to designate the terms of and issue new series of preferred stock without stockholder approval. Any series of preferred stock is likely to be senior to our Class A common stock with respect to dividends, liquidation rights and, possibly, voting rights.

Moreover, once holders of Class B common stock have less than 50% of the voting power of our issued and outstanding capital stock, (i) stockholders will not be permitted to act by written consent, (ii) supermajority voting requirements for amendment of our governing documents will become effective and (iii) the “business combination” provisions of Section 203 of the General Corporation Law of the State of Delaware, or the DGCL, will apply to us. Section 203 prohibits a person who acquires more than 15% but less than 85% of all classes of our outstanding voting stock without the approval of our board of directors from merging or combining with us for a period of three years, unless the merger or combination is approved by a two-thirds vote of the shares not owned by such person. These provisions would apply even if the proposed merger or acquisition could be considered beneficial by some stockholders.

The existence of the foregoing provisions and anti-takeover measures could limit the price that investors might be willing to pay in the future for shares of our Class A common stock. They could also deter potential acquirers of our company, thereby reducing the likelihood that you could receive a premium for your Class A common stock in an acquisition. See “Description of Capital Stock—Certain Provisions in Our Amended and Restated Certificate of Incorporation and Bylaws” for a discussion of these provisions.

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

We do not currently intend to pay dividends on our common stock. We plan to retain any earnings for use in the operation of our business and to fund future growth. Any future determination to pay dividends will be at the discretion of our board of directors.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

We have made statements under the captions “Prospectus Summary,” “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Business” and in other sections of this prospectus that are forward-looking statements. In some cases, you can identify these statements by forward-looking words such as “may,” “might,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “believes,” “estimates,” “predicts,” “potential” or “continue,” the negative of these terms and other comparable terminology. These forward-looking statements, which are subject to risks, uncertainties and assumptions about us, may include projections of our future financial performance, our anticipated growth strategies and anticipated trends in our business. These statements are only predictions based on our current expectations and projections about future events. There are important factors that could cause our actual results, level of activity, performance or achievements to differ materially from the results, level of activity, performance or achievements expressed or implied by the forward-looking statements, including those factors discussed under the caption entitled “Risk Factors.” You should specifically consider the numerous risks outlined under “Risk Factors.”

Although we believe the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance or achievements. Moreover, neither we nor any other person assumes responsibility for the accuracy and completeness of any of these forward-looking statements. We are under no duty to update any of these forward-looking statements after the date of this prospectus to conform our prior statements to actual results or revised expectations.

CHI-X EUROPE ACQUISITION

Acquisition Agreement

On February 18, 2011, we entered into a definitive agreement to acquire Chi-X Europe pursuant to which Chi-X Europe’s shareholders will receive, in the aggregate, approximately 4.4 million newly issued shares of our common stock and approximately $36 million in cash. In addition, pursuant to the acquisition agreement, a contingent cash payment of $30 million or $65 million may be due to Chi-X Europe’s shareholders in the fourth quarter of 2012 if one of the following market-share benchmarks is met in the six-month period beginning on the earliest of (a) June 1, 2012, if the transaction to acquire Chi-X Europe is completed on or before December 9, 2011; (b) July 1, 2012, if the transaction to acquire Chi-X Europe is completed after December 9, 2011; or (c) the first day of any month that is at least 60 days after BATS Europe and Chi-X Europe have completed integration and conversion of systems, including enabling Chi-X Europe’s trading participants to connect to and access BATS Europe’s systems: 1) a benchmark market share (calculated as our combined company’s matched market share in all of the securities included in 21 European indices plus certain additional securities set forth in the acquisition agreement) of at least 22% but less than 25% (which would result in a $30 million payment) or 2) a benchmark market share of 25% or more (which would result in a $65 million payment). For the second quarter of 2011, we had approximately 5.7% of such benchmark market share, and Chi-X Europe had approximately 17.8%.

In June 2011, the U.K. Office of Fair Trading referred our proposed acquisition of Chi-X Europe to the U.K. Competition Commission for further investigation. In July 2011, we, Chi-X Europe and Chi-X Europe’s shareholders agreed to an extension of the definitive agreement. The amended agreement includes a “break-up” provision that provides for a payment of up to $7 million from us to Chi-X Europe if the acquisition is not completed. The Competition Commission is expected to report by December 2011. Subject to receiving clearance from the regulatory authorities, we expect the transaction to close in the fourth quarter of 2011.

Upon the completion of the acquisition, Chi-X Europe’s assets, liabilities and operations, including amortization and depreciation expenses, will be reported under our European Equities segment. As a result of the acquisition, we will have goodwill of approximately $149.1 million that will be assessed for impairment under ASC 350—Intangibles—Goodwill and Other. We also expect to have approximately $99.4 million in identifiable intangible assets, which will result in approximately $3 million to $4 million in amortization expense in 2011. In addition, we expect to record the fair value of the liability for the contingent consideration of up to $65 million to be paid to the former owners of Chi-X Europe discussed above if certain criteria are met by June 2012. The fair value of the liability for the contingent consideration will be reassessed each reporting period, and any change in the liability will be recorded in our results of operations. We expect to incur one-time acquisition related costs of approximately $8 million to $10 million in 2011.

Strategic Rationale

We believe that our combination with Chi-X Europe will further our position as a leading transatlantic exchange operator and will solidify us as a preeminent pan-European trading venue. We expect to benefit from synergies as a result of the acquisition, including the transition of Chi-X Europe to our trading platform, which we expect to be completed during the second quarter of 2012, subject to receiving regulatory clearance for the acquisition. We believe the combination will improve our competitive position, enhance our profitability through scale and cost efficiencies and provide us additional opportunities to influence European market structure developments for the benefit of our customers. Once Chi-X Europe is fully integrated, we anticipate realizing annual cost efficiencies of approximately $8 million to $11 million as a result of savings from the consolidation of technology, operations and occupancy costs.

Overview of Chi-X Europe

Chi-X Europe is headquartered in London. For the second quarter of 2011, it operated the largest pan-European MTF with a 17.4% share of European trading in the securities available for trading on Chi-X Europe. Chi-X Europe currently offers trading in listed cash equity securities within 25 indices across 15 national

European markets, as well as ETFs, exchange-traded commodities and international depositary receipts, through two order books operated on a single platform. Chi-X Europe’s order books include a visible order book similar to BATS Europe and Chi-Delta, a stand-alone order book for non-displayed order matching or “dark pool,” which meets the needs of customers who wish to minimize the market impact of their orders. In March 2011, Chi-X Europe announced that it had created an alliance with Russell Investments to launch a new series of European indices. The new series will be constructed using Russell Investments’ index methodology and Chi-X Europe’s transaction prices as the primary underlying data source. Chi-X Europe intends to list futures and options contracts on the indices in the future as well as encourage the issuance of ETFs based upon the indices.

⁽¹⁾

Reflects the historical results of operations and financial condition of Chi-X Europe reconciled to U.S. GAAP from International Financial Reporting Standards, or IFRS, and converted from British pounds to U.S. dollars. See “Statement of Operations—Reconciliation from International Financial Reporting Standards to U.S. GAAP and Conversion from British Pound to U.S. Dollar For the Year Ended December 31, 2010,” “Statement of Operations—Reconciliation from International Financial Reporting Standards to U.S. GAAP and Conversion from British Pound to U.S. Dollar For the Six Months Ended June 30, 2011” and “Statement of Financial Condition—Reconciliation from International Financial Reporting Standards to U.S. GAAP and Conversion from British Pounds to U.S. Dollars As of June 30, 2011” tables below. The Chi-X Europe audited financial statements and related notes are included elsewhere in this prospectus.

⁽²⁾

Represents the effects of the acquisition of Chi-X Europe as if the acquisition had occurred on January 1, 2010. The pro forma statement of operations do not reflect the nonrecurring expenses that we expect to incur in connection with the Chi-X Europe acquisition, including approximately $9.0 million relating to fees to investment bankers, attorneys, accountants and other professional advisors in addition to severance and retention bonuses. The pro forma adjustments also do not reflect any cost savings or synergies we expect to realize after we integrate Chi-X Europe’s operations.

⁽³⁾

⁽⁴⁾

Represents annual amortization of identifiable intangible assets as a result of the purchase of Chi-X Europe. Amortization of identifiable intangible assets is based on the discounted cash flow method applied over the respective useful lives of the acquired intangible assets, except the FSA registration, which we have determined to have an indefinite life. The discounted cash flow method for the customer relationship and trade name assets will result in a decrease in amortization expense over their respective useful lives to match the economic benefit expected from these assets. The discounted cash flow method for the strategic alliance agreement will result in an increase in amortization expense over its useful life to match the economic benefit expected from this agreement. See Note 9 below.

⁽⁵⁾	Eliminates interest income earned on cash used in the acquisition of Chi-X Europe.

⁽⁶⁾	Represents the tax benefit of the amortization of intangible assets acquired and transaction-related expenses.

⁽⁷⁾	Represents the common stock issued in the acquisition of Chi-X Europe. See Note 9 below.

⁽⁸⁾	Represents the effects of the acquisition of Chi-X Europe as if the acquisition had occurred on June 30, 2011.

⁽⁹⁾	The following table summarizes the consideration to be paid for Chi-X Europe:


	Consideration (in millions)
Cash paid at closing	$	35.9
4,366,748 shares of our common stock		223.9	^(a)
Estimated value of contingent cash payment		45.6	^(b)

Total consideration to Chi-X Europe shareholders	$	305.4

(a)

Based on a third-party valuation as of May 6, 2011 and subject to change at time of close.

(b)

Consistent with Accounting Standards Codification, or ASC, 805—Business Combinations, we prepared the estimate of the fair value of the contingent consideration based on an evaluation of alternative scenarios relating to our and Chi-X Europe’s combined business and the benchmark market share under each scenario, the likelihood of each scenario and the amount of the contingent consideration payable under each scenario. The evaluation of these factors resulted in a probability-weighted forecast of the contingent consideration, which was then discounted to present value using an appropriate discount rate that reflects the risk associated with the cash flows. The sum of the present value of the contingent payment amounts represented our estimate of the fair value of the contingent consideration.

Under the purchase method of accounting, the total purchase price for the Chi-X Europe acquisition is allocated to acquired tangible and intangible assets based on preliminary estimates of their respective fair values upon the completion of the acquisition as determined by us and a third-party valuation firm. The preliminary allocation of the purchase price and the estimated useful life of the acquired intangible assets is as follows:


	Purchase Price Allocation (in millions)			Estimated Useful Life (in years)
Customer relationships	$	78.7			20
Trade name		0.9			2
Strategic alliance agreement		1.6			5
FSA registration		18.2			Infinite

Total acquired intangible assets		99.4
Goodwill		149.1

Total intangible assets		248.5

Current assets		59.7
Non-current assets		0.3
Fixed assets		5.6
Current liabilities		(8.0	)
Non-current liabilities		(0.7	)

Total cost of acquisition	$	305.4

Of the total purchase price, $56.9 million has been allocated to net tangible assets and working capital acquired, and approximately $81.2 million has been allocated to amortizable intangible assets acquired. The amortization related to the amortizable intangible assets is reflected as a pro forma adjustment to the unaudited pro forma condensed combined consolidated statements of income. See Note 6 above.

Of the total estimated purchase price, approximately $149.1 million has been allocated to goodwill. Goodwill represents the excess of the purchase price of an acquired business over the fair value of the underlying net tangible and intangible assets.

In accordance with FASB Accounting Standards Codification 350—Intangibles—Goodwill and Other, goodwill is not amortized but instead is tested for impairment on an annual basis and whenever events or circumstances dictate. In the event that we determine that the value of goodwill has become impaired, we will incur an accounting charge for the amount of impairment during the fiscal quarter in which the determination is made.

⁽¹⁰⁾	Represents elimination of Chi-X Europe’s capital for consolidated reporting.

RECLASSIFICATION AND STOCK SPLIT

Immediately prior to the completion of this offering, and pending approval by the SEC of amendments to our certificate of incorporation and bylaws pursuant to the rule filing process under Section 19(b) of the Exchange Act, we intend to amend and restate our certificate of incorporation to reclassify our common stock, par value $0.01 per share (which has been designated as Voting Common Stock in our certificate of incorporation), as Class A common stock, par value $0.01 per share, and Class B common stock, par value $0.01 per share. We also intend to reclassify our common stock, par value $0.01 per share (which has been designated as Non-Voting Common Stock in our certificate of incorporation), as Non-Voting Class A common stock, par value $0.01 per share, and Non-Voting Class B common stock, par value $0.01 per share.

Each share of our Voting Common Stock outstanding immediately prior to this offering will be converted into seven shares of Class A common stock and three shares of Class B common stock. Each share of our Non-Voting Common Stock outstanding immediately prior to this offering will be converted into seven shares of Non-Voting Class A common stock and three shares of Non-Voting Class B common stock. In addition, each outstanding option to purchase a share of our Voting Common Stock will be converted into an equivalent option to purchase ten shares of our Class A common stock.

Immediately following such reclassification and at any time thereafter, any share of Class B common stock that is held by a stockholder who, together with such stockholder’s affiliates, owns less than 4,960,491 shares of our common stock, which we refer to as the Class B Threshold, shall, automatically and without any further action, be converted into one share of Class A common stock, and each share of Non-Voting Class B common stock that is held at any time by a stockholder who, together with such stockholder’s affiliates, does not meet the Class B Threshold shall, automatically and without any further action, be converted into one share of Non-Voting Class A common stock. As a result of the reclassification and application of the Class B Threshold, each share of treasury stock held by us will be converted into ten shares of Class A common stock.

The table below sets forth the number of shares of stock or options that each stockholder or option holder will receive upon the reclassification and stock split for each share of stock or option held immediately prior to the completion of this offering:


	Post-Reclassification
Pre-Reclassification	Class A common stock	Non-Voting Class A common stock	Class B common stock	Non-Voting Class B common stock
1 share of voting common stock	shares	—	shares*	—
1 share of non-voting common stock	—	shares	—	shares*
1 option to purchase a share of voting common stock	options	—	—	—

*	Each share of Class B common stock or Non-Voting Class B common stock that is held by a stockholder who, together with such stockholder’s affiliates, fails to meet the Class B Threshold will be converted into Class A common stock or Non-Voting Class A common stock, respectively.

USE OF PROCEEDS

We estimate that our net proceeds from this offering will be approximately $ million, based on an assumed initial public offering price of $ per share, which is the mid-point of the price range set forth on the cover page of this prospectus, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us of $ million. We intend to use the net proceeds received by us in connection with this offering for general corporate purposes, including funding potential future strategic alliances or acquisitions that are complementary to our business or that enable us to enter new markets or provide new products or services.

We will not receive any proceeds from the sale of our Class A common stock by the selling stockholders in this offering.

⁽¹⁾

In conjunction with this offering, we intend to reclassify each share of our common stock which has been designated as Voting Common Stock as seven shares of Class A common stock and three shares of Class B common stock and each share of our common stock which has been designated as Non-Voting Common Stock as seven shares of Non-Voting Class A common stock and three shares of Non-Voting Class B common stock. Each share of Class A common stock will be entitled to one vote per share, and each share of Class B common stock will be entitled to two and one-half votes per share. Non-Voting Class A common stock and Non-Voting Class B common stock will not be entitled to vote, except as required by applicable law. See “Reclassification and Stock Split.” Non-Voting Class A common stock, Class B common stock and Non-Voting Class B common stock convert into Class A common stock in certain circumstances described under “Description of Capital Stock—Common Stock—Conversion.”

⁽²⁾	In connection with the Chi-X Europe acquisition, we will issue an aggregate of approximately 4.4 million shares of our common stock, including Voting Common Stock and Non-Voting Common Stock.

⁽³⁾

A $1.00 increase/(decrease) in the assumed initial public offering price of $ per share, which is the mid-point of the price range listed on the cover page of this prospectus, would increase/(decrease) the pro forma as adjusted amount of each of cash and cash equivalents, additional paid-in capital and total capitalization by approximately $ million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

⁽⁴⁾

If the underwriters’ option to purchase an additional shares of Class A common stock in this offering from is exercised in full, the pro forma as adjusted amount of each of additional paid-in capital and total capitalization would increase by approximately $ million, and we would have shares of our Class A common stock issued and outstanding.

The above table does not include:

•

shares of Class A common stock issuable upon the exercise of outstanding stock options with a weighted average exercise price of $ per share; and

•

an aggregate of additional shares of Class A common stock reserved for future issuance under our stock option plans as of June 30, 2011.

DILUTION

Dilution is the amount by which the portion of the offering price paid by the purchasers of our Class A common stock in this offering exceeds the net tangible book value per share of our common stock after the offering. Our pro forma net tangible book value (deficit) as of June 30, 2011 was $ , or $ per share of common stock. Pro forma net tangible book value per share is determined by dividing our tangible net worth (total tangible assets less total liabilities), by the aggregate number of shares of Class A common stock, Class B common stock, Non-Voting Class A common stock and Non-Voting Class B common stock outstanding. After giving effect to the reclassification and -for- stock split to be consummated immediately prior to the completion of this offering as described under “Reclassification and Stock Split,” and to the sale by us of the shares of Class A common stock in this offering at an assumed initial public offering price of $ per share of Class A common stock, the mid-point of the range set forth on the cover page of this prospectus; and the receipt and application of the net proceeds, our pro forma net tangible book value at June 30, 2011 would have been $ or $ per share. This represents an immediate increase in pro forma net tangible book value to existing stockholders of $ per share and an immediate dilution to new investors of $ per share. The following table illustrates this per share dilution:


Assumed initial public offering price per share of Class A common stock		$
Pro forma net tangible book value (deficit) per share of common stock as of June 30, 2011	$
Increase in pro forma net tangible book value per share of common stock attributable to new investors

Pro forma net tangible book value per share after offering

Dilution per share of Class A common stock to new investors		$

Dilution is determined by subtracting pro forma net tangible book value per share of common stock after the offering from the initial public offering price per share of Class A common stock.

The following table sets forth, on a pro forma basis, as of June 30, 2011, the number of shares of Class A common stock purchased from us, the total consideration paid, or to be paid, and the average price per share paid, or to be paid, by existing stockholders and by the new investors, at an assumed initial public offering price of $ per share of Class A common stock, the mid-point of the range set forth on the cover page of this prospectus, before deducting estimated underwriting discounts and commissions and offering expenses payable by us:


	Shares Purchased				Total Consideration				Average Price Per Share
	Number	Percent			Amount	Percent			Average Price Per Share
Existing stockholders				%	$			%	$
New investors

Total			100	%	$		100	%	$

Sales by the selling stockholders in this offering will reduce the number of shares of Class A common stock held by existing stockholders to , or approximately %, and will increase the number of shares of Class A common stock to be purchased by new investors to , or approximately %, of the total shares of Class A common stock outstanding after the offering. In addition, selling stockholders will hold % of the Class B common stock. Shares of our Class B common stock are not transferable until three years after the date of this prospectus. After such period, shares of Class B common stock may be transferred, in which case they will automatically convert into Class A common stock except in certain limited circumstances as described under “Description of Capital Stock—Common Stock—Conversion.”

The foregoing tables assume no exercise of outstanding stock options after June 30, 2011. At June 30, 2011, shares of Class A common stock were subject to outstanding options, at a weighted average exercise price of $ . To the extent these options are exercised there will be further dilution to new investors. See “Management—Stock Plans” and Note 11 to our consolidated financial statements included elsewhere in this prospectus.

“EBITDA” is defined as income before interest, income taxes, depreciation and amortization. Adjusted EBITDA is defined as EBITDA before stock-based compensation expense. EBITDA and Adjusted EBITDA do not represent, and should not be considered as, alternatives to net income or cash flows from operations, each as determined in accordance with U.S. GAAP. We have presented EBITDA and Adjusted EBITDA because we consider them important supplemental measures of our performance and believe that they are frequently used by analysts, investors and other interested parties in the evaluation of companies. Other companies may calculate EBITDA and Adjusted EBITDA differently than we do. EBITDA and Adjusted EBITDA have limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results as reported under U.S. GAAP.

The following is a reconciliation of net income (loss) to EBITDA and Adjusted EBITDA:

MANAGEMENT’S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the notes thereto included in this prospectus. The following discussion contains forward-looking statements. Actual results could differ materially from the results discussed in the forward-looking statements. See “Risk Factors” and “Special Note Regarding Forward-Looking Statements” above.

Overview

We are an innovative global financial technology company that develops and operates electronic markets for the trading of listed cash equity securities in the United States and Europe and listed equity options in the United States. Our principal objective is to make markets better by minimizing inefficiencies and mitigating trade execution risk for market participants. We minimize inefficiencies in part by offering low-cost, rapid, trade execution. We mitigate trade execution risk through offering ultra-low latency order handling through our trading system. In particular, by offering ultra-low latency order handling, our members can very quickly place, modify or cancel orders on our markets. This ability gives our members greater control over their orders, enabling them to rapidly respond to changing market conditions and mitigate trade execution risk. Unlike traditional market operators, we are a technology company at our core. We developed, own and operate the BATS trading platform. Our proprietary platform powers all of our markets and is designed to offer one of the fastest and most reliable trading systems available.

We began trading listed cash equities securities in the United States in the first quarter of 2006 and in Europe during the fourth quarter of 2008, and we began offering trading in listed equity options in the United States during the first quarter of 2010. For the second quarter of 2011, we had a 10.8% share of the U.S. equity market and a 3.9% share of the U.S. equity options market. In Europe, for the same period, we had a 5.6% share of European trading in the securities available for trading on BATS Europe. For the six months ended June 30, 2011 and 2010, we derived 91.5% and 97.7%, respectively, of our total revenues from the trading of listed cash equities securities in the United States.

Our revenue is primarily tied to the volume of securities traded on our markets and our market share of trading in the overall U.S. and European equity markets and the U.S. equity options market. Trading volume on our markets can be influenced by a number of factors, including overall market volatility. Our revenue increased from $22.4 million in 2006 to $834.8 million in 2010. This revenue growth is attributable to our increased market share and increased overall market volume, as well as the introduction of new products and services.

For the six months ended June 30, 2011, our revenues less cost of revenues were $49.8 million, which represents a decrease of 2.4% from the six months ended June 30, 2010. For the year ended December 31, 2010, our revenues less cost of revenues were $99.2 million, which represents an increase of 25.7% from the year ended December 31, 2009. A substantial portion of our revenues less cost of revenues is derived from market data fees, which represented 52.2% and 43.1% of revenues less cost of revenues for the six months ended June 30, 2011 and 2010, respectively, and 46.4% and 64.2% of revenues less cost of revenues for the years ended December 31, 2010 and 2009, respectively.

History

In January 2007, we introduced an inverted pricing special during which our market share of trading in NASDAQ-listed cash equity securities increased from 4.9% at the beginning of that month to 9.6% at the end of

that month and averaged 8.0% per month for the remainder of that year. We began trading NYSE-listed securities in February 2007 and offered a one-month inverted pricing special in NYSE-listed securities in September 2007. Our market share of NYSE-listed securities increased from 2.7% for the month of August 2007 to 7.2% for the month of September 2007 and averaged 5.5% per month for the remainder of that year. We also offered an inverted pricing special on NYSE Arca- and NYSE Amex-listed securities from August 31, 2007 through April 30, 2009, during which time our market share of such securities grew from 5.7% for the month of August 2007 to 14.3% for the month of April 2009 and averaged 14.7% per month for the remainder of 2009.

In March 2008, we decided to enter the European market and sought approval from the Financial Services Authority, or FSA, to operate a multilateral trading facility, or MTF. Our MTF, which we refer to as BATS Europe, offers trading in cash equity securities listed on 15 national exchanges across Europe. Seeking to compete on a pan-European basis against incumbent national exchanges, we launched BATS Europe in October 2008. Based on our success with pricing specials in the United States, BATS Europe offered inverted pricing specials in September 2009 on securities listed on the London Stock Exchange, or LSE, from June 2009 through July 2009 on securities listed on certain NYSE Euronext European markets and from June 2009 through October 2009 on all exchange-traded funds, or ETFs, traded on BATS Europe. For the second quarter of 2011, BATS Europe was the second largest pan-European MTF in terms of market share and had a 5.6% share of European trading in the securities available for trading on BATS Europe.

In November 2008, we converted our ECN to a national securities exchange, BZX, which allowed us to participate in and earn market data fees from the U.S. tape plans, reduce our clearing costs and operate a primary listings business, which we recently announced plans to launch.

In February 2010, in the United States, we began trading U.S. listed equity options on BZX. While we did not offer any inverted pricing specials on our U.S. listed equity options market in 2010, we recently introduced the concept of “NBBO setter” pricing, which refers to customers who set the national best bid or best offer, or NBBO, for a listed equity option. NBBO setter pricing provides customers who execute a specified minimum volume with higher liquidity rebates for listed equity options orders posted on our market that improve the then current NBBO. This in turn provides better execution prices for other customers. We initiated NBBO setter pricing on our U.S. listed equity options market in January 2011, and our share of the U.S. equity options market increased from approximately 0.7% for the month of December 2010 to 4.3% for the month of June 2011.

In order to grow our market share of the U.S. equity market, in October 2010, we launched BYX, a second national securities exchange. Like BZX, BYX offers trading in listed cash equity securities and exchange-traded products, such as ETFs, but BYX targets different market segments than BZX by offering an alternative approach. BYX had captured approximately a 2.5% share of the U.S. equity market for the month of June 2011. In addition, in order to continue to capture market share, we are currently offering an inverted pricing special on BYX. Also, similar to NBBO setter pricing described above for listed equity options on BZX, BYX and BZX implemented NBBO setter pricing in May 2011 and July 2011, respectively, for listed cash equity securities. For the second quarter of 2011, BZX and BYX combined had a 10.8% share of the U.S. equity market, and we were the third largest exchange operator in the United States after NYSE Euronext and The NASDAQ OMX Group, Inc., based on total market share of the markets that we operate.

As discussed below, in February 2011, we signed a definitive agreement to acquire Chi-X Europe, which operates the largest pan-European MTF.

Business Segments

We currently operate along three business segments. Our management allocates resources, assesses performance and manages our business according to these segments:

•

U.S. Equities. Our U.S. Equities segment includes listed cash equities transaction services that occur on our national securities exchanges in the United States, BZX and BYX. This segment commenced

operations in January 2006 with our ECN and was our only segment until the addition of European Equities in October 2008. For the six months ended June 30, 2011, the U.S. Equities segment represented 91.5% of our total revenues. For the year ended December 31, 2010, the U.S. Equities segment represented 96.8% of our total revenues.

•

European Equities. Our European Equities segment includes the pan-European listed cash equities transaction services that occur on our MTF, BATS Europe. This operation launched in October 2008, and our European Equities segment accounted for 3.0% of our total revenues for the six months ended June 20, 2011 and 2.3% of our total revenues for the year ended December 31, 2010.

•

U.S. Options. Our U.S. Options segment includes our listed equity options market on BZX. We began offering trading in listed equity options in February 2010, and our U.S. Options segment contributed 5.5% of our total revenues for the six months ended June 30, 2011 and 0.9% of our total revenues for the year ended December 31, 2010. Currently, BYX does not offer trading in listed equity options.

Chi-X Europe Acquisition

In February 2011, we entered into a definitive agreement to acquire Chi-X Europe pursuant to which Chi-X Europe’s shareholders will receive, in the aggregate, approximately 4.4 million newly issued shares of our common stock and approximately $36 million in cash. In addition, we may pay up to an additional $65 million in cash to Chi-X Europe’s shareholders in the fourth quarter of 2012, if certain market-share benchmarks are met. We expect to benefit from various synergies as a result of the acquisition, including the transition of Chi-X Europe to our trading platform, which we expect to be completed during the second quarter of 2012, subject to regulatory clearance of the acquisition. In June 2011, the U.K. Office of Fair Trading referred our proposed acquisition of Chi-X Europe to the U.K. Competition Commission for further investigation. In July 2011, we, Chi-X Europe and Chi-X Europe’s shareholders agreed to an extension of the definitive agreement. The amended agreement includes a “break-up” provision that provides for a payment of up to $7 million from us to Chi-X Europe if the acquisition is not completed. The Competition Commission is expected to report by December 2011. Subject to clearance from the regulatory authorities, we expect the transaction to close in the fourth quarter of 2011. We expect to incur one-time acquisition related costs of approximately $8 million to $10 million in 2011.

The acquisition will be accounted for under the acquisition method of accounting prescribed in Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, 805—Business Combinations. Under the acquisition method, the acquisition price will be allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their respective fair values, with the remainder allocated to goodwill. The fair values recorded for property and equipment, trade name, customer relationships and contracts or other identifiable intangible assets will result in material additional depreciation and amortization expense after the consummation of the acquisition. The amount of depreciation and amortization is based upon the fair values and the estimated useful lives of the respective assets.

Upon the completion of the acquisition, Chi-X Europe’s assets, liabilities and operations, including amortization and depreciation expenses, will be reported under our European Equities segment. As a result of the acquisition, we will have goodwill of approximately $149.1 million that will be assessed for impairment under ASC 350—Intangibles—Goodwill and Other. We also expect to have approximately $99.4 million in identifiable intangible assets, which will result in approximately $3 million to $4 million in amortization expense in 2011. In addition, we expect to record the fair value of the liability for the contingent consideration of up to $65 million to be paid to the former owners of Chi-X Europe if certain criteria are met by June 2012. The fair value of the liability for the contingent consideration will be reassessed each reporting period, and any change in the liability will be recorded in our results of operations.

Our Model

Like many of our competitors, we have adopted a “maker-taker” or “taker-maker” pricing model in our markets instead of the historical pricing model in the U.S. listed equity securities market that involves charging a

transaction fee for each party to a trade. The maker-taker pricing model is designed to incentivize market makers to provide liquidity on a continuous basis. Participants are attracted to markets that have continuous, deep liquidity, which provides more opportunity to buy and sell equities immediately and with minimal adverse effect on prices. Because market makers supply a valuable service to markets by providing liquidity, maker-taker pricing rewards them with a rebate.

Under our maker-taker pricing model, on BZX (for both listed cash equity securities and listed equity options) and on BATS Europe, a customer posting an order on our book, which we refer to as the liquidity maker, is paid a rebate for an execution occurring against that order, and a customer executing against an order resting on our book, which we refer to as the liquidity taker, is charged a fee. We generate a substantial portion of our operating income from the difference between the “maker” rebate and the “taker” fee. We believe this type of fee schedule is attractive to customers who regularly provide liquidity. Although customers must pay a fee to access that liquidity, that fee is explicitly disclosed and charged to all customers and potentially results in a better all-in transaction price than could be obtained on an exchange using a historical pricing model.

The BYX “taker-maker” pricing model provides that a liquidity taker will be paid a rebate for executing against an order resting on our book, and the liquidity provider will be charged a fee for posting such an order. In this case, we generate operating income from the difference between the “maker” fee and the “taker” rebate. Currently, both the fee and the rebate are significantly less than the rebates and fees in place on BZX. We believe this appeals to market participants who are primarily interested in the most cost-effective means of accessing resting liquidity, but less concerned about the depth of liquidity available on the market. In addition, we believe this model appeals to market participants trading lower-priced securities.

As mentioned above, on occasion, we offer pricing specials on our markets in order to attract additional liquidity and gain market share. In such cases, we may rebate slightly more to the liquidity maker, in the case of BZX and BATS Europe, or slightly more to the liquidity taker, in the case of BYX, than we collect in fees from the other party to the trade. While pricing specials may decrease our per-transaction profitability while in effect, they have historically generated incremental trading and quoting activity, which in turn generates increased market data revenue from our share of the revenue collected from the U.S. tape plans. Moreover, our focus when entering new markets is to quickly grow market share and then focus on profitability once we have achieved critical mass and increased liquidity. We believe that offering such pricing specials for temporary periods of time induces our customers to send us additional orders and that much of any resulting gain in market share will sustain itself upon the expiration of a pricing special.

For unfilled orders, we also provide our customers a smart-order routing service, enabling the onward routing of unfilled orders to other market centers. In the United States, this is facilitated through our wholly-owned broker-dealer subsidiary, BATS Trading. In Europe, BATS Trading Limited was granted regulatory permission to operate an order routing facility on December 2, 2009 and is one of the few market centers in Europe that provides such routing services for lit venues.

In addition, in the United States, we derive a substantial portion of our revenue from market data fees, discussed below under “Components of Revenue—Market Data Fees,” which reflect our proportionate share of revenue from the U.S. tape plans with respect to trades matched on BZX and BYX.

Components of Revenues

Our revenues consist of:

•

transaction fees;

•

market data fees;

•

regulatory transaction fees; and

•

other.

The primary and largest source of our revenues is transaction fees.

Transaction Fees

General

Total transaction fees during a period are variable, based on trading volume and pricing per share on our U.S. listed cash equity markets, pricing as a percentage of notional value on our European listed cash equities market and pricing per contract on our U.S. listed equity options market.

Transaction fees consist of “taker” fees (or in the case of BYX, “maker” fees) and routing fees charged on securities that are routed out to another market center. Transaction fees are considered earned upon the execution of the trade and are recognized on a trade-date basis. The “taker” fees (or in the case of BYX, “maker” fees) from transactions executed through our markets are recorded on a gross basis in revenues, with “maker” rebates (or in the case of BYX, “taker” rebates) recorded on a gross basis in cost of revenues. Transaction fee revenues accounted for 74.8% and 81.6% of our total revenues for the six months ended June 30, 2011 and 2010, respectively, and 80.1%, 80.4% and 93.1% of our total revenues for the years ended December 31, 2010, 2009 and 2008, respectively.

•

We earn transaction fees in the United States from the trading of listed cash equity securities on our two national securities exchanges, BZX and BYX. U.S. listed cash equity securities trading revenues are assessed on a per-share basis. Transaction fees from U.S. Equities accounted for 89.3% of our total transaction fees for the six months ended June 30, 2011 and 96.1% of our total transaction fees for the year ended December 31, 2010.

•

We earn transaction fees in Europe from the trading of listed cash equity securities on BATS Europe. European listed cash equity securities trading revenues are assessed on a notional-value basis. We launched our European operations in October 2008. Transaction fees from our European operations accounted for 4.0% of our total transaction fees for the six months ended June 30, 2011 and 2.9% of our total transaction fees for the year ended December 31, 2010.

•

We earn transaction fees from the trading of listed equity options on BZX. U.S. listed equity options trading revenues are assessed on a per-contract basis. Transaction fees from U.S. Options accounted for 6.7% of our total transaction fees for the six months ended June 30, 2011 and 1.0% of our total transaction fees for the year ended December 31, 2010.

Trading volumes

Transaction fees for U.S. Equities, European Equities and U.S. Options are primarily dependent on overall market volume and our market share thereof.

U.S. Equities. The U.S. listed cash equity securities markets have historically experienced growth in trading volumes. From time to time, however, volumes have declined due to economic performance, volatility and other related factors.

During the period from 2003 to 2007, the U.S. listed cash equity securities market indices experienced substantial growth. Overall market volumes also increased dramatically, in part as a result of regulatory changes, including the implementation of Regulation NMS. See “Business—Industry Overview.” In 2008, the U.S. economy entered a recession on the heels of a macroeconomic credit crisis, resulting in a severe decline in equity market indices, an increase in volatility and a severely challenging business environment. While there are indications that the economy began to emerge from the recession in mid-2009, today the economic and geopolitical climates remain uncertain, volatility has declined and overall market volumes are substantially below their peak in 2009.

The following summarizes changes in our U.S. Equities segment average daily trading volume, or ADV, for the six months ended June 30, 2011 and 2010:

ADV for our U.S. Equities segment was 944.8 million shares in the six months ended June 30, 2011, compared to 1,165.2 million in the six months ended June 30, 2010, a decrease of 18.9%. Average daily matched shares in our U.S. Equities segment decreased 16.0% for the same time periods. The total U.S. equities market ADV decreased 20.2% in the six months ended June 30, 2011 compared to the six months ended June 30, 2010. Total trading days in the United States during the six months ended June 30, 2011 and 2010 were 125 and 124, respectively.

Our U.S. Equities segment volume decreased during the six months ended June 30, 2011 compared to the six months ended June 30, 2010 as a result of the economic climate, reduced volatility, overall market volumes being substantially below their 2009 peaks and, in part, Citi’s reverse stock split in the second quarter of 2011. The U.S. Equities segments volume for the six months ended June 30, 2010 also reflects the volatility resulting from the events of May 6, 2010. However, our market share of the U.S. equity market remained relatively constant, increasing from 10.7% for the six months ended June 30, 2010 to 10.8% for the six months ended June 30, 2011.

The following summarizes changes in our U.S. Equities segment ADV for the years ended December 31, 2010, 2009 and 2008 and the percent changes in our ADV from 2009 to 2010 and from 2008 to 2009:
