PART I

Forward-Looking Statements

This report contains certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by words such as “expects,” “intends,” “anticipates,” “plans,” “believes,” “seeks,” “estimates,” “will,” or words of similar meaning and include, but are not limited to, statements regarding the outlook for our future business and financial performance. Forward-looking statements are based on management’s current expectations and assumptions, which are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. It is routine for our internal projections and expectations to change as the year or each quarter in the year progresses, and therefore it should be clearly understood that the internal projections and beliefs upon which we base our expectations may change prior to the end of each quarter or the year. Although these expectations may change, we are under no obligation to revise or update any forward-looking statements contained in this report. Our company policy is generally to provide our expectations only once per quarter, and not to update that information until the next quarter. Actual future events or results may differ, perhaps materially, from those contained in the projections or forward-looking statements. Factors that could cause or contribute to such differences include those discussed below and elsewhere in this report, particularly in Item 1A “Risk Factors.”

Item 1. Business.

MarketAxess Holdings Inc. (the “Company” or “MarketAxess”) operates a leading electronic trading platform that allows investment industry professionals to efficiently trade corporate bonds and other types of fixed-income instruments. Our approximately 1,000 active institutional investor clients (firms that executed at least one trade in U.S. or European fixed-income securities through our electronic trading platform during 2012) include investment advisers, mutual funds, insurance companies, public and private pension funds, bank portfolios, broker-dealers and hedge funds. Our 87 broker-dealer market-maker clients provide liquidity on the platform and include most of the leading broker-dealers in global fixed-income trading. Through our Corporate BondTicker^TM service, we provide fixed-income market data, analytics and compliance tools that help our clients make trading decisions. In addition, we provide FIX (Financial Information eXchange) message management tools, connectivity solutions and ancillary technology services that facilitate the electronic communication of order information between trading counterparties. Our revenues are primarily generated from the trading of U.S. high-grade corporate bonds.

Our multi-dealer trading platform allows our institutional investor clients to simultaneously request competing, executable bids or offers from our broker-dealer clients and execute trades with the broker-dealer of their choice from among those that choose to respond. We offer our broker-dealer clients a solution that enables them to efficiently reach our institutional investor clients for the distribution and trading of bonds. In addition to U.S. high-grade corporate bonds, European high-grade corporate bonds and emerging markets bonds, including both investment-grade and non-investment grade debt, we also offer our clients the ability to trade crossover and high-yield bonds, agency bonds, asset-backed and preferred securities and credit default swaps (“CDS”).

The majority of our revenues are derived from monthly distribution fees and commissions for trades executed on our platform that are billed to our broker-dealer clients on a monthly basis. We also derive revenues from technology products and services, information and user access fees, investment income and other income. Our expenses consist of employee compensation and benefits, depreciation and amortization, technology and communication costs, professional and consulting fees, occupancy, marketing and advertising and general and administrative expenses.

Traditionally, bond trading has been a manual process, with product and price discovery conducted over the telephone between two or more parties. This traditional process has a number of shortcomings resulting primarily from the lack of a central trading facility for these securities, which creates difficulty matching buyers and sellers for particular issues. Many corporate bond trading participants use e-mail and other electronic means of communication for trading corporate bonds. While this has addressed some of the shortcomings associated with traditional corporate bond trading, we believe that the process is still hindered by limited liquidity, limited price transparency, significant transaction costs, compliance and regulatory challenges, and difficulty in executing numerous trades at one time.

Through our disclosed multi-dealer Request For Quote (“RFQ”) trading functionality, our institutional investor clients can determine prices available for a security, a process called price discovery, as well as trade securities directly with our broker-dealer clients. The price discovery process includes the ability to view indicative prices from the broker-dealer clients’ inventory available on our platform, access to real-time pricing information and analytical tools (including spread-to-Treasury data, search capabilities and independent third-party credit research) available on our Corporate BondTicker^TM service and the ability to request executable bids and offers simultaneously from up to 58 of our broker-dealer clients during the trade process. On average, institutional investor clients receive several bids or offers from broker-dealer clients in response to trade inquiries. However, some trade inquiries may not receive any bids or offers.

Table of Contents

Our services relating to trade execution include single and multiple-dealer inquiries; list trading, which is the ability to request bids and offers on multiple bonds at the same time; and swap trading, which is the ability to request an offer to purchase one bond and a bid to sell another bond, in a manner such that the two trades will be executed simultaneously, with payment based on the price differential of the bonds. Once a trade is completed on our platform, the broker-dealer client and institutional investor client may settle the trade with the assistance of our automated post-trade messaging, which facilitates the communication of trade acknowledgment and allocation information between our institutional investor and broker-dealer clients.

Typically, we are not a party to the trades that occur on our platform between institutional investor clients and broker-dealer clients; rather, we serve as an intermediary between broker-dealers and institutional investors, enabling them to meet, agree on a price and then transact with each other. However, we also execute certain bond transactions between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller in matching back-to-back trades, which are then settled through a third-party clearing organization.

Our broker-dealer clients accounted for approximately 95% of the underwriting of newly-issued U.S. corporate bonds and approximately 72% of the underwriting of newly issued European corporate bonds in 2012. We believe these broker-dealers also represent the principal source of secondary market liquidity in the other markets in which we operate. Secondary market liquidity refers to the ability of market participants to buy or sell a security quickly and in large volume subsequent to the original issuance of the security, without substantially affecting the price of the security. In addition to trading fixed-income securities by traditional means, including the telephone and e-mail, our broker-dealer clients use proprietary single-dealer systems and other trading platforms as well as our electronic trading platform. We believe that the traditional means of trading remain the manner in which the majority of bonds are traded between institutional investors and broker-dealers.

Our volume in U.S. high-grade corporate bonds represented approximately 12.4% of the total U.S. high-grade corporate bond volume, excluding convertible bonds, for 2012, as reported by the Financial Industry Regulatory Authority (“FINRA”) Trade Reporting and Compliance Engine (“TRACE”), which includes inter-dealer and retail trading as well as trading between institutional investors and broker-dealers.

On October 26, 2012, we entered into an agreement to acquire all of the outstanding shares of Xtrakter Limited (“Xtrakter”) from Euroclear S.A./N.V. Xtrakter is a U.K.-based provider of regulatory transaction reporting, financial market data and trade matching services to the European securities markets. The acquisition of Xtrakter will provide us with an expanded set of technology solutions ahead of incoming regulatory mandates in Europe.

The aggregate purchase price is £26.0 million (approximately $40.5 million) in cash, plus transaction costs, and is subject to a post-closing adjustment based on the net working capital of Xtrakter on the closing date. The purchase price will be funded from available cash on hand. We received Financial Service Authority (“FSA”) approval of the change in control on February 18, 2013 and expect to complete the acquisition of Xtrakter on or about February 28, 2013.

Industry Background

Fixed-income securities are issued by corporations, governments and other entities, and pay a pre-set absolute or relative rate of return. As of September 30, 2012, the most recent date available, there were approximately $37.7 trillion principal amount of fixed-income securities outstanding in the U.S. market, including $8.6 trillion principal amount of U.S. corporate bonds, according to the Securities Industry and Financial Markets Association (“SIFMA”). The estimated average daily trading volume of U.S. corporate bonds (investment grade and high-yield), as measured by TRACE, was $16.3 billion in 2012.

The U.S. and European credit markets experienced a period of significant turmoil beginning during the third quarter of 2007, especially in short-term funding and floating rate note instruments. A widespread retrenchment in the credit markets resulted in increased credit spreads and significantly higher credit spread volatility across a wide range of asset classes. The U.S. credit markets demonstrated significant improvement since 2008. In addition, primary dealer holdings of corporate bonds due in more than one year as reported by the Federal Reserve Bank of New York declined from approximately $218 billion as of December 31, 2007 to $57 billion as of December 31, 2012. The trading volume of U.S. high-grade corporate bonds as reported by TRACE has remained approximately $2.9 trillion for each of the four calendar years in the period ended December 31, 2012, after declining to $2.0 trillion for the year ended December 31, 2008. After demonstrating improved conditions during 2009, the European credit markets have deteriorated due in part to continuing sovereign debt credit concerns.

U.S. High-Grade Corporate Bond Market

The U.S. corporate bond market consists of three broad categories of securities: investment-grade debt (so-called “high-grade”), which typically refers to debt rated BBB- or better by Standard & Poor’s or Baa3 or better by Moody’s Investor Service; debt rated below investment-grade (so-called “high-yield”), which typically refers to debt rated lower than BBB- by Standard & Poor’s or Baa3 by Moody’s Investor Service; and debt convertible into equity (so-called “convertible debt”). We use the terms high-grade debt and investment-grade debt interchangeably in this Annual Report on Form 10-K.

The U.S. high-grade corporate bond market, which represents the largest subset of the U.S. corporate bond market, has undergone significant change over the last decade, which has been driven by a number of factors, including:

Table of Contents

European High-Grade Corporate Bond Market

The European high-grade corporate bond market consists of a broad range of products, issuers and currencies. We define the European high-grade corporate bond market generally to consist of bonds intended to be distributed to European investors, primarily bonds issued by European corporations, excluding bonds that are issued by corporations domiciled in an emerging markets country and excluding most government bonds that trade in Europe. Examples include:

We believe that the European high-grade corporate bond market is impacted by many of the same factors as the U.S. high-grade corporate bond market. In addition, we believe the following factors are unique to the European high-grade corporate bond market:

Emerging Markets Bond Market

We define the emerging markets bond market generally to include U.S. dollar, Euro or local currency denominated bonds issued by sovereign entities or corporations domiciled in a developing country. These issuers are typically located in Latin America, Asia, or Central and Eastern Europe. Examples of countries we classify as emerging markets include: Argentina, Brazil, Colombia, Mexico, Peru, the Philippines, Russia, Turkey and Venezuela.

The institutional investor base for emerging markets bonds includes many crossover investors from the high-yield and high-grade investment areas. Institutional investors have been drawn to emerging markets bonds by their high returns and high growth potential. The average daily trading volume of emerging markets external and local markets debt as reported by the Emerging Markets Trade Association for the quarter ended September 30, 2012 was $6.8 billion and $14.0 billion, respectively.

Crossover and High-Yield Bond Market

We define the high-yield bond market generally to include all debt rated lower than BBB- by Standard & Poor’s or Baa3 by Moody’s Investor Service. We define the crossover market to include any debt issue rated below investment grade by one agency but investment grade by the other. The total amount of high-yield corporate bonds yearly issuance as reported by SIFMA declined by 68% to $43.0 billion during 2008 from $136.0 billion in 2007, primarily due to the risk aversion among corporate bond investors that severely limited the ability of high-yield issuers to raise new debt. The high-yield corporate bond markets demonstrated significant improvement beginning in 2009, with new issuance for the year ended December 31, 2012 increasing to $328.7 billion as reported by SIFMA.

FINRA publicly disseminates real-time price information on over 5,000 high-yield corporate bond issues and disseminates price information about certain other transactions on a delayed basis. Trades in bonds rated BB and lower are subject to immediate dissemination if the trade size is less than $1 million, or greater than $1 million and the bond trades an average of once or more a day.

-6-

Table of Contents

The average daily trading volume of high-yield bonds as measured by TRACE for the year ended December 31, 2012 was approximately $4.3 billion.

Agency Bond Market

We define the agency bond market to include debt issued by a U.S. government-sponsored enterprise. Some prominent issuers of agency bonds are the Federal National Mortgage Association (“Fannie Mae”) and Federal Home Loan Mortgage Corporation (“Freddie Mac”). The total amount of U.S. agency bonds outstanding was approximately $2.4 trillion as of December 31, 2012 as reported by SIFMA. The average daily trading volume of agency bonds (excluding mortgage-backed securities) as measured by TRACE for the year ended December 31, 2012 was approximately $10.8 billion.

Credit Default Swap Market

Credit default swaps are contracts on an underlying asset that transfer risk and return from one party to another without transferring ownership of the underlying asset, allowing market participants to obtain credit protection or assume credit exposure associated with a broad range of issuers of fixed-income securities and other debt obligations. The trading volumes and notional amount outstanding in CDS transactions grew rapidly between 2002 and 2007. Following counterparty credit concerns beginning in 2007, trading activity in the CDS market declined substantially and the industry focused on netting down counterparty positions. The notional amount of CDS outstanding declined to $26.9 trillion as of June 30, 2012 from $62.2 trillion as of December 31, 2007. To address the counterparty credit concerns, structural changes began to occur in the CDS market that included the creation of CDS clearing houses in 2009 that serve as central counterparties for certain CDS transactions. In 2010, in response to the financial crisis, the U.S. Congress passed the Dodd-Frank Act, which is intended to bring comprehensive reform to the regulation of swaps, including CDS. Among the most significant provisions of the derivatives section of the Dodd-Frank Act are: mandatory clearing, through regulated central clearing organizations, of all swaps that the U.S. Commodity Futures Trading Commission (“CFTC”) or the U.S. Securities and Exchange Commission (“SEC”) has determined should be cleared (“clearable swaps”); and mandatory trading of clearable swaps on a board of trade designated as a contract market or a securities exchange or through a “swap execution facility,” or SEF (in each case, subject to certain key exceptions). While we expect that the CFTC and SEC will adopt rules that detail the new regulatory regime regarding the swaps market place in 2013, no assurance can be given regarding when, or whether, such rules will be finalized and implemented. Subject to such rulemaking, we intend to establish, register and operate a swap execution facility and/or a security-based swap execution facility. We believe that the introduction of the clearing mandates is likely to result in more standardized contracts and greater price transparency in the CDS markets.

Although the European regulators have not yet introduced legislation concerning regulation of the European derivatives markets, the European Parliament and the EU Council of Ministers endorsed an agreement that will, among other things, require central clearing of standardized OTC derivatives and the reporting of all derivatives (OTC or otherwise) to trade repositories. However, it is not yet clear whether there will be any requirement in the EU to trade standardized derivative contracts on regulated exchanges or trading platforms.

Asset-Backed Securities

Asset-backed securities are ownership interests in a pool of receivables sold by originators into a special purpose vehicle. These securities are typically secured by pools of homogeneous assets with relatively predictable cash flows. The assets are legally separated from the seller, which limits the investor’s exposure to the credit quality of the seller. In 2012, approximately $180.0 billion in U.S. consumer-based asset-backed securities (defined as including auto, credit cards, equipment and student loans) and non-agency residential and commercial mortgage-backed securities were issued. New issuance declined from over $1.0 trillion in 2007 as the asset-backed securities market was significantly impacted by the credit and housing market crisis. The total amount of consumer-based asset-backed and non-agency residential and commercial mortgage-backed securities outstanding at December 31, 2012 was $2.5 trillion, as reported by SIFMA.

Preferred Securities

Preferred securities are equity ownership securities that carry additional rights above and beyond those conferred by common shares. The additional rights typically include preference in dividends and seniority in assets vis-à-vis common stock in the event of liquidation. Other typical features include convertibility into common stock, callable at the option of the corporation and no voting rights.

Our Competitive Strengths

Our electronic trading platform provides solutions to some of the shortcomings of traditional bond trading methods. The benefits of our solution are demonstrable throughout the trading cycle:

We believe that we are well positioned to strengthen our market position in electronic trading in our existing products and to extend our presence into new products and services by capitalizing on our competitive strengths, including:

Significant Trading Volumes with Participation by Leading Broker-Dealers and Institutional Investors

Our electronic trading platform provides access to the liquidity provided through the participation on our platform of 87 broker-dealer market-making clients, including substantially all of the leading broker-dealers in global fixed-income trading, and approximately 1,000 active institutional investor firms. We believe these broker-dealers represent the principal source of secondary market liquidity for U.S. high-grade corporate bonds, European high-grade corporate bonds, emerging markets bonds and the other markets in which we operate. Our broker-dealer clients are motivated to continue to utilize our platform due to the presence on the platform of our large network of institutional investor clients. We believe that our net addition of 38 new broker-dealer market-making clients since the third quarter of 2008 has improved and will continue to improve the liquidity on our electronic trading platform for institutional investors, further motivating them to use our platform. The number of our active institutional investor clients for the past five years has been as follows:

-8-

Table of Contents

Our total trading volume increased from $226.4 billion in 2008 to $589.6 billion in 2012. We believe that our trading volumes in 2008 and 2009 reflect the turmoil and resultant lack of liquidity in the credit markets beginning in the third quarter of 2007. Our total trading volume over the past five years is indicated below:

Our volume in U.S. high-grade corporate bonds was approximately 6.6% of total U.S. high-grade corporate bond volume, excluding convertible bonds, in 2008 as reported by TRACE, which includes inter-dealer and retail trading as well as trading between institutional investors and broker-dealers. Following the credit market turmoil, our estimated market share declined to approximately 6.2% for the full year 2009. Our estimated share of total U.S. high-grade corporate bond volume for 2012 was approximately 12.4%, double the estimated market share in 2009, due in part to improved U.S. credit market conditions, increased client order flow and higher order execution rates. Our estimated market share from 2008 to 2012 is shown in the chart below:

Execution Benefits to Clients

Benefits to Institutional Investor Clients

We believe we provide numerous benefits to our institutional investor clients over traditional fixed-income trading methods, including:

Competitive Prices. By enabling institutional investors to simultaneously request bids or offers from our broker-dealer clients, we believe our electronic trading platform creates an environment that motivates our broker-dealer clients to provide competitive prices and gives institutional investors confidence that they are obtaining a competitive price. For typical MarketAxess multi-dealer corporate bond inquiries, the range of competitive spread-to-Treasury responses is, on average, approximately 10 basis points (a basis point is 1/100 of 1% in yield). As an example of the potential cost savings to institutional investors, a one basis point savings on a $1 million face amount trade of a bond with 10 years to maturity translates to aggregate savings of approximately $800.00.

Transparent Pricing on a Range of Securities. The commingled multi-dealer inventory of bonds posted by our broker-dealer clients on our platform consists of a daily average of more than $45 billion in indicative bids and offers. Subject to applicable regulatory requirements, institutional investors can search bonds in inventory based on any combination of issuer, issue, rating, maturity, spread-to-Treasury, size and dealer providing the listing, in a fraction of the time it takes to do so manually. Institutional investor clients can also request executable bids and offers on our electronic trading platform on any debt security in a database of U.S. and European corporate bonds, although there can be no assurance as to the number of broker-dealers who will choose to provide an executable price. Our platform transmits bid and offer requests in real-time to broker-dealer clients, who may respond with executable prices within the time period specified by the institutional investor. Institutional investors may also elect to display live requests for bids or offers anonymously to all other users of our electronic trading platform, in order to create broader visibility of their inquiry among market participants and increase the likelihood that the request results in a trade. We believe that broader participation in client inquiries will result in more trade matches and lower transaction costs.

Improved Cost Efficiency. We believe that we provide improved efficiency by reducing the time and labor required to conduct broad product and price discovery. Single-security and multi-security (bid or offer lists) inquiries can be efficiently conducted with multiple broker-dealers. In addition, our Corporate BondTicker^TM eliminates the need for manually-intensive phone calls or e-mail communication to gather, sort and analyze information concerning historical transaction prices.

Benefits to Broker-Dealer Clients

We also provide substantial benefits to our broker-dealer clients over traditional fixed-income trading methods, including:

Greater Sales Efficiency. We offer our broker-dealer clients broad connectivity with our institutional investor clients. Through this connectivity, our broker-dealer clients are able to efficiently display their indications of interest to buy and sell various securities. We also enable broker-dealers to broaden their distribution by participating in transactions to which they otherwise may not have had access. In addition, the ability to post prices and electronically execute on straightforward trades enables bond sales professionals at broker-dealer firms to focus their efforts on more profitable activities, such as higher value-added trades and more complex transactions.

More Efficient Inventory Management. The posting of inventory to, and the ability to respond to inquiries from, a broad pool of institutional investors, creates an increased opportunity for broker-dealers to identify demand for their inventory, particularly in less liquid securities. As a result, we believe they can achieve enhanced bond inventory turnover, which may limit credit exposure.

Benefits to Both Institutional Investor and Broker-Dealer Clients

We offer additional benefits over traditional fixed-income trading methods that are shared by both institutional investor and broker-dealer clients, including:

Greater Trading Accuracy. Our electronic trading platform includes verification mechanisms at various stages of the execution process which result in greater accuracy in the processing, confirming and clearing of trades between institutional investor and broker-dealer clients. These verification mechanisms are designed to ensure that our broker-dealer and institutional investor clients are sending accurate trade messages by providing multiple opportunities to verify they are trading the correct bond, at the agreed-upon price and size. Our platform assists our institutional investor clients in automating the transmittal of order tickets from the portfolio manager to the trader, and from the trader to back-office personnel. This automation provides more timely execution and a reduction in the likelihood of errors that can result from manual entry of information into different systems.

Table of Contents

Efficient Risk Monitoring and Compliance. Institutional investors and their regulators are increasingly focused on ensuring that best execution is achieved for fixed-income trades. Our electronic trading platform offers both institutional investors and broker-dealers an automated audit trail for each stage in the trading cycle. This enables compliance personnel to review information relating to trades more easily and with greater reliability. Trade information including time, price and spread-to-Treasury is stored securely and automatically on our electronic trading platform. This data represents a valuable source of information for our clients’ compliance personnel. Importantly, we believe the automated audit trail, together with the competitive pricing that is a feature of our electronic trading platform, gives fiduciaries the ability to demonstrate that they have achieved best execution on behalf of their clients.

Other Service Offerings

In addition to services directly related to the execution of trades, we offer our clients several other services, including:

Information Services. The information and analytical tools we provide to our clients help them make investment and trading decisions. Our Corporate BondTicker^TM provides access to real-time and historical price, yield and MarketAxess estimated spread-to-Treasuries for publicly disseminated TRACE-eligible bonds. Corporate BondTicker^TM combines publicly-available TRACE data with the prices for trades executed on our U.S. high-grade electronic trading platform, integrating the two data sources and providing real-time TRACE data with associated analytical tools that are not otherwise available. Our electronic trading platform allows institutional investors to compile, sort and use information to discover investment opportunities that might have been difficult or impossible to identify using a manual information-gathering process or other electronic services.

We offer a comprehensive set of reports designed to review and monitor credit trading activity for institutional investor clients. These reports utilize extensive TRACE information and are accessible by means of a flexible interface to run and save reports in a variety of formats for both compliance and management reporting. For example, the best execution report provides a view of the savings generated by trading on our electronic trading platform and offers a quantitative measure of the value of price discovery from multiple dealers. The report allows clients to monitor performance against their own best execution policy. Our compliance product provides a printed history of each inquiry submitted through the MarketAxess trading platform.

Straight-Through Processing. Straight-through processing (“STP”) refers to the integration of systems and processes to automate the trade process from end-to-end — trade execution, confirmation and settlement — without the need for manual intervention. Our electronic trading platform provides broker-dealers and institutional investors with the ability to automate portions of their transaction processing requirements, improving accuracy and efficiency. Through electronic messaging, institutional investors can submit inquiries to, and receive electronic notices of execution from us, in industry standard protocols, complete with all relevant trade details. Institutional investors can download trade messages, allocate trades to the sub-accounts on whose behalf the trades were made and send the allocations to broker-dealers for confirmation.

Technology Products and Services. We provide integration, testing and management solutions for FIX-related products and services designed to optimize the electronic trading of fixed-income, equity and other exchange-based products. We also provide technology consulting and customized development services to our clients that leverage our trading technology expertise and our existing technology solutions. In addition, we provide gateway adapters to connect order management and trading systems to fixed-income trading venues.

Robust, Scalable Technology

We have developed proprietary technology that is highly secure, fault-tolerant and provides adequate capacity for our current operations, as well as for substantial growth. Our highly scalable systems are designed to accommodate additional volume, products and clients with relatively little modification and low incremental costs.

Proven Innovator with an Experienced Management Team

Since our inception, we have been an innovator in the fixed-income securities markets. The members of our management team average more than 20 years of experience in the securities industry. We have consistently sought to benefit participants in the markets we serve by attempting to replicate the essential features of fixed-income trading, including the existing relationships between broker-dealers and their institutional investor clients, while applying technology to eliminate weaknesses in traditional trading methods. In 2012, MarketAxess was named “Best OTC Derivatives Platform” in Wall Street Letter’s Annual Institutional Trading, and was listed among Risk magazine’s “25 Firms of the Future.” Most recently, MarketAxess was recognized as one of the “100 Fastest Growing Companies” by Fortune.

Some of the innovations we have introduced to electronic trading include:

Our Strategy

Our objective is to provide the leading global electronic trading platform for fixed-income securities, connecting broker-dealers and institutional investors more easily and efficiently, while offering a broad array of information, trading and technology services to market participants across the trading cycle. The key elements of our strategy are:

Enhance the Liquidity of Securities Traded on Our Platform and Broaden Our Client Base in Our Existing Markets

We intend to further enhance the liquidity of securities traded on our leading electronic, multi-dealer to client fixed-income platform. Our ability to innovate and efficiently add new functionality and product offerings to the MarketAxess platform will help us deepen our market share with our existing clients, as well as expand our client base, which we believe will, in turn, lead to even further increases in the liquidity of the securities provided by our broker-dealer clients and available on our platform. We will seek to increase the amount of cross-regional activity by our institutional investor clients on our electronic trading platform, subject to regulatory requirements.

Leverage our Existing Technology and Client Relationships to Expand into New Sectors of the Fixed-Income Securities Market

We intend to leverage our technology, as well as our strong broker-dealer and institutional investor relationships, to deploy our electronic trading platform into additional product segments within the fixed-income securities markets and deliver fixed-income securities-related technical services and products. Due in part to our highly scalable systems, we believe we will be able to enter new markets efficiently. As an example, we have developed technology and trading protocols to trade CDS in anticipation of implementation of the Dodd-Frank Act and, subject to such rulemaking, we currently expect to establish and operate a swap execution facility and/or a security-based swap execution facility.

Leverage our Existing Technology and Client Relationships to Expand into New Client Segments

We intend to leverage our technology and client relationships to deploy our electronic trading platform into new client segments. As an example, we have expanded the base of broker-dealers on our platform to include both regional and diversity dealers.

Continue to Strengthen and Expand our Trade-Related Service Offerings

We plan to continue building our existing service offerings so that our electronic trading platform is more fully integrated into the workflow of our broker-dealer and institutional investor clients. We also plan to continue to add functionality to enhance the ability of our clients to achieve a fully automated, end-to-end straight-through processing solution (automation from trade initiation to settlement). We are continually considering the introduction of new trading techniques.

Expand our Data and Information Services Offerings

We regularly add new content and analytical capabilities to Corporate BondTicker^TM in order to improve the value of the information we provide to our clients. We intend to continue to widen the user base of our data products and to continue adding new content and analytical capabilities. As the use of our electronic trading platform continues to grow, we believe that the amount and value of our proprietary trading data will also increase, further enhancing the value of our information services offerings to our clients.

Expand our Technology Services Offerings

We intend to leverage our technology expertise and our client relationships to provide technology solutions to our clients that enhance their electronic trading capabilities and facilitate the electronic communication of order information with their trading counterparties.

Pursue Select Acquisitions and Strategic Alliances

We plan to continue to increase and supplement our internal growth by entering into strategic alliances, or acquiring businesses or technologies, that will enable us to enter new markets, provide new products or services, or otherwise enhance the value of our platform to our clients.

On October 26, 2012, we entered into an agreement to acquire all of the outstanding shares of Xtrakter from Euroclear S.A./N.V. Xtrakter is a U.K.-based provider of regulatory transaction reporting, financial market data and trade matching services to the European securities markets. The acquisition of Xtrakter will provide us with an expanded set of technology solutions ahead of incoming regulatory mandates in Europe.

MarketAxess Electronic Trading Platform

Key Trading Functionalities

The key trading functionalities are detailed below.

Single Inquiry Trading Functionality

We currently offer institutional investors the ability to request bids or offers in a single inquiry from an unlimited number of our broker-dealer clients for U.S. high-grade corporate bonds, from up to six of our broker-dealer clients for European high-grade corporate bonds and from up to 12 of our broker-dealer clients in emerging markets bonds. Institutional investors can obtain bids or offers on any security posted in inventory or included in the database available on our platform.

ASAP and Holding Bin Trading Functionalities

We provide both ASAP (“as soon as possible”) and Holding Bin trading protocols. In the Holding Bin trading protocol, institutional investor clients set the time when they would like all of the broker-dealers’ prices or spreads returned to them, in order to have the ability to see all executable prices available at the same time. In the ASAP trading protocol, institutional investor clients see each broker-dealer’s price or spread as soon as it is entered by the broker-dealer.

List Trading Functionality

We currently offer institutional investors the ability to request bids or offers on a list of up to 40 bonds depending on the market. This facilitates efficient trading for institutional investors such as investment advisors, mutual funds and hedge funds. Institutional investors are able to have multiple lists executable throughout the trading day, enabling them to manage their daily cash flows, portfolio duration, and credit and sector exposure.

Table of Contents

Swap Trading Functionality

We currently offer institutional investors the ability to request an offer to purchase one bond and a bid to sell another bond, in a manner such that the two trades will be executed simultaneously, with payment based on the price or yield differential of the securities.

Market Lists

We offer institutional investors the ability to display live requests for bids and offers anonymously to the entire MarketAxess trading community through our Market List functionality, thereby creating broader visibility of their inquiry among market participants and increasing the likelihood that the request results in a trade.

Inventory and Axes

The price discovery process includes the ability to view indications of interest from both broker-dealer clients and, beginning in 2012, institutional investor clients inventory on our platform. Through the aggregated indication of interest inventory, clients can search for bonds of interest and engage in electronic transactions.

Click-to-Trade

We have enhanced our trading system to provide pre-trade price discovery and fast-track execution for European bonds. Click-to-trade functionality streams attributable pricing in European credit and rates instruments, submitted by our pool of European dealers. Investor clients are able to initiate an inquiry with a single click on the stacks of distinctly displayed dealer bids and offers. Click-to-trade is offered alongside our existing Request for Quote product. Although currently limited to European credit and rate instruments, click-to-trade functionality may be applied to trading of other market sectors.

Central Limit Order Book

We have offered central limit order book (“CLOB”) style trading for bonds and CDS in the past. While the characteristics of the corporate bond market have not been conducive to continuous trading (as in equity markets), we believe there is a sub-set of actively traded bonds and CDS that could benefit from CLOB trading. We expect to re-introduce CLOB trading in 2013.

Client-to-Dealer Trading

U.S. High-Grade Corporate Bonds

Our U.S. high-grade corporate bond business consists of U.S. dollar-denominated investment-grade debt issued by corporations for distribution in the U.S. Both domestic and foreign institutional investors have access to U.S. high-grade corporate bond trading on our electronic trading platform. Our 2012 trading volume in the U.S. high-grade corporate bond market was $367.7 billion.

In the U.S. high-grade corporate bond market, 58 broker-dealers utilize our platform, including all of the top 20 broker-dealers as ranked by 2012 U.S. corporate bond new-issue underwriting volume. Our broker-dealer clients accounted for approximately 95% of the underwriting of newly-issued U.S. corporate bonds in 2012.

We offer our institutional investor clients access to a broad inventory of U.S. high-grade corporate bonds, which is provided and updated daily by our broker-dealer clients. Our electronic trading platform allows institutional investors to view bids and offers from one or more of our broker-dealer clients while permitting each party to know the identity of its counter-party throughout the trading process. Our disclosed inquiry trading functionality combines the strength of existing offline client/dealer relationships with the efficiency and transparency of an electronic trading platform. This enables institutional investors to instantly direct trade inquiries and negotiations to their traditional broker-dealer or to any of the substantial majority of the world’s leading broker-dealers who provide liquidity in these securities. Through our Market List functionality, we also offer institutional investors the ability to display their live requests for bid and offer lists anonymously to the entire MarketAxess trading community as a means of creating broader visibility of their inquiry among market participants and increasing the likelihood that the request results in a trade.

-14-

Table of Contents

Institutional investors have access to the commingled inventory of our broker-dealer clients, representing indicative bids and offers. Each line item of inventory represents an indicative bid and/or offer on a particular bond issue by a particular broker-dealer client. Institutional investor clients are not restricted to trading only the bonds posted as inventory, although many of the trades conducted on our platform are made from the posted inventory. To transact in a specific bond that does not appear in inventory, institutional investors can easily search our database and submit an online inquiry to their chosen broker-dealers, who can respond with live, executable prices. While, on average, institutional investor clients receive several bids or offers from broker-dealers in response to trade inquiries, some inquiries may not receive any bids or offers.

Eurobonds

MarketAxess Europe Limited, our wholly-owned U.K. subsidiary, offers European secondary trading functionality in U.S. dollar- and Euro-denominated European corporate bonds to our broker-dealer and institutional investor clients. We also offer our clients the ability to trade in other European high-grade corporate bonds, including bonds issued in Pounds Sterling, floating rate notes, European government bonds and bonds denominated in non-core currencies. We offered the first platform in Europe with a multi-dealer disclosed counterparty trading capability for corporate bonds. In 2009, MarketAxess Europe Limited received FSA regulatory approval to trade on a riskless principal basis. In 2010, we launched a click-to-trade protocol for the European market.

In the Eurobond credit market, defined as including European high-grade, high-yield and government bonds, 23 broker-dealers utilize our platform, including 17 of the top 20 broker-dealers as ranked by 2012 European corporate new-issue underwriting volume. On a typical day, institutional investors on our European corporate bond trading platform have access to over 120,000 lines of streaming pre-trade price indications on over 14,000 individual instruments covered on both the bid and offer side of the market. In a single inquiry, institutional investors can request bids or offers from up to six of the broker-dealers who participate on the European platform. While many of the trades conducted on our platform are made from the posted inventory, institutional investor clients are not restricted to trading only the bonds posted as inventory. To transact in a specific bond that does not appear in inventory, institutional investors can easily search our database and submit an online inquiry to their chosen broker-dealers, who can respond with live, executable prices. While, on average, institutional investor clients receive several bids or offers from broker-dealers in response to trade inquiries, some inquiries may not receive any bids or offers. Our 2012 trading volume in the Eurobond market was $34.5 billion.

Emerging Markets Bonds

Fifty-nine of our U.S. broker-dealer clients use our platform to trade emerging markets bonds. Four hundred ninety-three active institutional investor clients utilized our electronic trading platform to trade emerging markets bonds in 2012. These institutional investor clients are predominantly located in the U.S. and Europe. The emerging markets countries whose bonds were most frequently traded on our platform in 2012 were Brazil, Mexico, Venezuela, Russia and Argentina.

We also allow our institutional investor clients to transact Euroclear-eligible local currency denominated bonds issued by sovereign entities or corporations in countries that include Argentina, Brazil and Mexico.

Crossover and High-Yield Bonds

Fifty-nine of our U.S. broker-dealer clients use our platform to trade crossover and high-yield bonds. Trading in crossover and high-yield bonds uses many of the same features available in our U.S. high-grade corporate bond offering.

Agency Bonds

Forty-one of our U.S. broker-dealer clients use our platform to trade agency bonds. Trading in agency bonds uses many of the same features available in our U.S. high-grade corporate bond offering.

Credit Default Swaps

We offer trading on our platform for CDS indices, index options and single-names in both the U.S. and Europe through our traditional RFQ protocol. We are streaming executable dealer markets in CDS and European indices. Ten of our broker-dealer clients are providing streaming, executable CDS index prices. We have incorporated the request-for-market protocol and the streaming markets/click-to-trade protocol into an updated single-screen user interface, giving clients full flexibility in their means of execution. With these features, we believe that we have developed much of the core technology needed to meet the anticipated regulatory requirements under the Dodd-Frank Act.

Table of Contents

Asset-Backed Securities

In 2011, we introduced trading in consumer-based asset-backed securities and non-agency residential and commercial mortgage-backed securities. Twelve of our U.S. broker-dealer clients use our platform to trade asset-backed securities. Trading in asset-backed securities uses many of the same features available in our U.S. high-grade corporate bond offerings.

Preferred Securities

In November 2010, we introduced trading in preferred securities. Seventeen of our U.S. broker-dealer clients use our platform to trade preferred securities. Trading in preferred securities uses many of the same features available in our U.S. high-grade corporate bond offering.

Dealer-to-Dealer Trading

Through our DealerAxess^® platform, our broker-dealer clients can access liquidity provided by over 100 global, regional and specialist dealers. In addition to fully-disclosed RFQ trading, we offer an anonymous RFQ trading protocol for inter-dealer trading, helping dealers more efficiently manage their bond inventory. We offer trading across a wide range of fixed income products including high-grade, high-yield, emerging markets and U.S. agency bonds. Dealers active on our client-to-dealer platform benefit from existing trade routing rules and books, straight-through processing connectivity and trading APIs. Bond trades on DealerAxess^® executed pursuant to the anonymous protocol are conducted with MarketAxess as riskless principal and cleared and settled by an independent clearing broker.

Information and Analytical Tools

Corporate BondTicker^TM

Corporate BondTicker^TM provides real-time TRACE data and enhances it with MarketAxess trade data and analytical tools in order to provide professional market participants with a comprehensive set of corporate bond price information. The data include trade time and sales information, including execution prices, as well as MarketAxess-estimated spread-to-Treasuries, for trades disseminated by the TRACE system. The data also include actual execution prices and spread-to-Treasury levels for U.S. high-grade corporate bond trades executed on the MarketAxess platform.

Corporate BondTicker^TM allows institutional investors to search for and sort bonds based upon specific criteria, such as volume, time/date of transaction, spread change, issuer or security. This search function allows institutional investors to compile information relating to potential securities trades in a fraction of the time that it takes to manually compile this information from disparate sources or other electronic databases, including direct TRACE feeds.

TRACE facilitates the mandatory reporting of over-the-counter secondary market transactions in eligible fixed-income securities. All broker-dealers that are FINRA member firms have an obligation to report transactions in corporate bonds to TRACE under a set of rules approved by the SEC. FINRA then publicly disseminates a portion of this data, which is available free of charge on a delayed basis through the FINRA website or available immediately for a set fee.

Corporate BondTicker^TM is integrated directly into the MarketAxess electronic trading platform and can be seamlessly accessed, either when viewing securities inventory or when launching an inquiry. Corporate BondTicker^TM is also available through the Internet for non-trading professional market participants, including, among others, research analysts and rating agencies, who can log in and access the information via an easy-to-use browser-based interface.

We provide Corporate BondTicker^TM as an ancillary service to our trading clients and also to other industry participants. We derive revenues from our Corporate BondTicker^TM service by charging for seat licenses per user at our broker-dealer and institutional investor clients, through distribution agreements with other information service providers and through bulk data sales to third parties. Seat license fees are waived for clients that transact a sufficient volume of trades through MarketAxess.

Table of Contents

Additional analytical capabilities of our information services offerings aim to provide clients with more information regarding bond prices and market activity, including asset swap spreads, turnover percentage and liquidity ratios. These statistics measure a security’s trading activity relative to its amount outstanding and relative to the overall market, respectively, providing an additional perspective on relative liquidity. In addition, we provide pricing measures to help institutional investors better assess the relative value of a corporate bond, providing more consistent relative pricing information for institutional investors, such as offering spread data versus the interest rate swap curve and versus the U.S. Treasury curve. Users are also able to download a variety of MarketAxess-compiled trade reports containing a comprehensive review of trading activity. Corporate BondTicker^TM is currently the source of corporate bond trading information for The Wall Street Journal.

We also offer a comprehensive set of reports designed to review and monitor credit trading activity for institutional investor clients. These reports utilize extensive TRACE information and have a flexible interface to run and save in a variety of formats for both compliance and management reporting. For example, the best execution report provides a view of the savings generated by trading on our electronic trading platform and offers a quantitative measure of the value of price discovery from multiple dealers. The report allows clients to monitor performance against their own best execution policy. Our compliance product provides a printed history of each inquiry submitted through the MarketAxess trading platform.

My Portfolio

Institutional investors are able to upload their corporate bond portfolio to our electronic trading platform utilizing the “My Portfolio” trading feature. Institutional investors who utilize “My Portfolio” benefit from the ability to automatically match inventory on our platform to bonds held in their portfolio, allowing them to more efficiently launch an inquiry and transact in these securities. Users of this feature can also directly access Corporate BondTicker^TM to obtain the trading history of the securities in their portfolio.

Straight-Through Processing

Straight-through processing refers to the integration of systems and processes to automate the trade process from end-to-end — trade execution, confirmation and settlement — without the need for manual intervention. There are two elements of straight-through processing: internal straight-through processing and external straight-through processing. Internal straight-through processing relates to the trade and settlement processes that are internal to an industry participant. For example, in the case of an institutional investor, this includes authorization of orders, placement of orders with broker-dealers, receipt of execution details and allocation of trades. External straight-through processing refers to connecting seamlessly to all external counterparts in the trading and settlement process.

Automation by way of straight-through processing improves efficiency throughout the trade cycle. We provide broker-dealers and institutional investors with a range of tools that facilitate straight-through processing, including order upload, easy-to-use online allocation tools and pre- and post-trade messaging features that enable institutional investors to communicate electronically between front- and back-office systems, thereby integrating the order, portfolio management and accounting systems of our broker-dealer and institutional investor clients in real time. Our straight-through processing tools can be customized to meet specific needs of clients. We continue to build industry partnerships to assist our clients in creating connectivity throughout the trade cycle. Through these partnerships, we are increasingly providing solutions that can quickly be deployed within our clients’ trading operations.

Usage of our straight-through processing tools increased significantly during the last several years. The number of investor client STP connections increased from 180 as of December 31, 2008 to 325 as of December 31, 2012.

Dealer API

We offer Application Programming Interface (“API”) services to our broker-dealer clients for pre-trade, trade negotiation and post-trade services. This allows for straight-through processing, which improves efficiency and reduces errors in processing.

Technology Services

Through our Greenline Financial Technologies, Inc. (“Greenline”) subsidiary, we provide integration, testing and management solutions for FIX-related products and services. The FIX protocol is a messaging standard developed specifically for the real-time electronic exchange of securities transaction information. Greenline’s CertiFIX product enables firms to provide a reliable FIX certification environment for their trading counterparties. The VeriFIX product is a testing suite that allows firms to thoroughly test counterparty FIX interfaces, protocol formats and supported messages. Greenline’s MagniFIX product allows firms to monitor their enterprise-wide FIX installations on a real-time basis. In addition, Greenline provides strategic consulting and custom development for its clients.

Table of Contents

We also provide technology consulting and customized development services to our clients that leverage our trading technology expertise and our existing technology solutions. Fees for such services are based on the complexity and extent of the services provided. In addition, we provide gateway adapters to connect order management and trading systems to fixed-income trading venues.

Sales and Marketing

We promote our products and services using a variety of direct and indirect sales and marketing strategies. Our sales force is responsible for client acquisition activity and for increasing use of our platform by our existing clients. Their goal is to train and support existing and new clients on how to use the system and to educate them as to the benefits of utilizing an electronic fixed-income trading platform. We employ various strategies, including advertising, direct marketing, promotional mailings and participation in industry conferences, to increase awareness of our brand and our electronic trading platform. For example, we have worked with The Wall Street Journal to establish Corporate BondTicker^TM as the source of information for its daily corporate bond and high-yield tables.

Competition

The electronic trading industry is highly competitive and we expect competition to intensify in the future. We face five main areas of competition:

Competitors, including companies in which some of our broker-dealer clients have invested, have developed electronic trading platforms or have announced their intention to explore the development of electronic trading platforms that compete or will compete with us. Furthermore, our broker-dealer clients have made, and may in the future continue to make investments in or enter into agreements with other businesses that directly or indirectly compete with us.

-18-

Table of Contents

In general, we compete on the basis of a number of key factors, including:

We believe that our ability to grow volumes and revenues will largely depend on our performance with respect to these factors.

Our competitive position is also enhanced by the familiarity and integration of our broker-dealer and institutional investor clients with our electronic trading platform and other systems. We have focused on the unique aspects of the credit markets we serve in the development of our platform, working closely with our clients to provide a system that is suited to their needs.

Our broker-dealer clients have invested in building API’s with us for inventory contributions, electronic trading, government bond benchmark pricing and post-trade messaging. We believe that we have successfully built deep roots with our broker-dealer clients, increasing our level of service to them while at the same time increasing their commitment to our services.

Furthermore, 325 of our institutional investor clients have built interfaces to enable them to communicate electronically between our platform and their order, portfolio management and accounting systems. We believe that this increases the reliance of these institutional investor clients on our services and creates significant competitive barriers to entry.

Technology

The design and quality of our technology products are critical to our growth and our ability to execute our business strategy. Our electronic trading platform has been designed with secure, scalable client-server architecture that makes broad use of distributed computing to achieve speed, reliability and fault tolerance. The platform is built on industry-standard technologies and has been designed to handle many multiples of our current trading volume.

All critical server-side components, primarily our networks, application servers and databases, have backup equipment running in the event that the main equipment fails. This offers fully redundant system capacity to maximize uptime and minimize the potential for loss of transaction data in the event of an internal failure. We also seek to minimize the impact of external failures by automatically recovering connections in the event of a communications failure. The majority of our broker-dealer clients have redundant dedicated high-speed communication paths to our network in order to provide fast data transfer. Our security measures include industry-standard communications encryption.

We have designed our application with an easy-to-use, Windows-based interface. Our clients are able to access our electronic trading platform through a secure, single sign-on. Clients are also able to execute transactions over our platform directly from their order management systems. We provide users an automatic software update feature that does not require manual intervention.

Intellectual Property

We rely upon a combination of copyright, patent, trade secret and trademark laws, written agreements and common law to protect our proprietary technology, processes and other intellectual property. Our software code, elements of our electronic trading platform, website and other proprietary materials are protected by copyright laws. We have been issued 11 patents, including five patents issued in 2009 covering our most significant trading protocols and other aspects of our trading system technology, and additional patents are pending.

-19-

Table of Contents

The written agreements upon which we rely to protect our proprietary technology, processes and intellectual property include agreements designed to protect our trade secrets. Examples of these written agreements include third party nondisclosure agreements, employee nondisclosure and inventions assignment agreements, and agreements with customers, contractors and strategic partners. Other written agreements upon which we rely to protect our proprietary technology, processes and intellectual property take many forms and contain provisions related to patent, copyright, trademark and trade secret rights.

We have obtained U.S. federal registration of the MarketAxess^® name and logo, and the same mark and logo have been registered in several foreign jurisdictions. In addition, we have obtained U.S. federal registration for the marks AutoSpotting^®, FrontPage^®, Actives^®, DealerAxess^® and associated designs and have a number of other registered trademarks and service marks. Corporate BondTicker^TM is a trademark we use, but it has not been registered.

In addition to our efforts to register our intellectual property, we believe that factors such as the technological and creative skills of our personnel, new product and service developments, frequent enhancements and reliability with respect to our services are essential to establishing and maintaining a technology and market leadership position.

Government Regulation

The securities industry and financial markets in the U.S. and elsewhere are subject to extensive regulation. As a matter of public policy, regulatory bodies in the U.S. and the rest of the world are charged with safeguarding the integrity of the securities and other financial markets and with protecting the interests of investors participating in those markets. Our active broker-dealer subsidiaries fall within the scope of their regulations.

Regulation of the U.S. Securities Industry and Broker-Dealers

In the U.S., the SEC is the governmental agency responsible for the administration of the federal securities laws. One of our U.S. subsidiaries, MarketAxess Corporation, is registered with the SEC as a broker-dealer. It is also a member of FINRA, a self-regulatory organization to which most broker-dealers belong. In addition, MarketAxess Corporation is a member of the Securities Investor Protection Corporation, which provides certain protection for clients’ accounts in the event of a liquidation of a broker-dealer to the extent any such accounts are held by the broker-dealer.

Additionally, MarketAxess Corporation is registered with certain states and the District of Columbia as a broker-dealer. The individual states and the District of Columbia are responsible for the administration of their respective “blue sky” laws, rules and regulations.

In July 2010, the Dodd-Frank Act was signed into law. U.S. financial regulators are in the midst of an intense period of rulemaking that is required to implement the provisions of the Dodd-Frank Act, and market participants will need to make strategic decisions in an environment of regulatory uncertainty. Among the most significant aspects of the derivatives section of the Dodd-Frank Act are mandatory clearing of certain derivatives transactions (“swaps”) through regulated central clearing organizations and mandatory trading of those swaps through either regulated exchanges or swap execution facilities, in each case, subject to certain key exceptions. As with other parts of the Dodd-Frank Act, many of the details of the new regulatory regime relating to swaps are left to the regulators to determine through rulemaking. While we expect that the CFTC and SEC will adopt rules that detail the new regulatory regime regarding the swaps market place in 2013, no assurance can be given regarding when, or whether, such rules will be finalized and implemented. Subject to such rulemaking, we currently expect to establish and operate a swap execution facility and/or a security-based swap execution facility.

Regulation of the Non-U.S. Securities Industries and Investment Service Providers

The securities industry and financial markets in the U.K., the European Union and elsewhere are subject to extensive regulation. MarketAxess Europe Limited may fall within the scope of those regulations depending on the extent to which it is characterized as providing a regulated investment service.

Our principal regulator in the U.K. is the FSA. Our subsidiary, MarketAxess Europe Limited, is registered as a Multilateral Trading Facility (“MTF”) dealer with the FSA. Xtrakter Limited is registered, and upon consummation of the pending acquisition will continue to be registered, as an Approved Reporting Mechanism with the FSA. Xtrakter also has “recognized status” in France, the Netherlands and Belgium in connection with the submission of transaction reports to regulators.

-20-

Table of Contents

The securities industry in the member states of the European Union is regulated by agencies in each member state. European Union measures provide for the mutual recognition of regulatory agencies and of prudential supervision making possible the grant of a single authorization for providers of investment services, which, in general, is valid throughout the European Union. As an FSA approved MTF, MarketAxess Europe Limited receives the benefit of this authorization.

Similar to the U.S., regulatory bodies in Europe and elsewhere are developing new rules for derivatives trading. For example, the European Parliament and the EU Council of Ministers endorsed an agreement that will, among other things, require central clearing of standardized OTC derivatives and the reporting of all derivatives (OTC or otherwise) to trade repositories. However, it is not yet clear whether there will be any requirement in the EU to trade standardized CDS contracts on regulated exchanges or trading platforms.

Our Canadian subsidiary, MarketAxess Canada Limited, is registered as an Alternative Trading System dealer under the Securities Act of Ontario and is a member of the Investment Industry Regulatory Organization of Canada.

Employees

As of December 31, 2012, we had 240 employees, 194 of whom were based in the U.S. and 46 of whom were based outside of the U.S., principally in the U.K. None of our employees is represented by a labor union. We consider our relationships with our employees to be good and have not experienced any interruptions of operations due to labor disagreements.

Item 1A. Risk Factors.

Risks Related to Our Business

Global economic, political and market factors beyond our control could reduce demand for our services, and our profitability and business could suffer.

The global financial services business is, by its nature, risky and volatile and is directly affected by many national and international factors that are beyond our control. Any one of these factors may cause a substantial decline in the U.S. and/or global financial services markets, resulting in reduced trading volume. These events could have a material adverse effect on our business, financial condition and results of operations. These factors include:

Any one or more of these factors may contribute to reduced activity and prices in the securities markets generally. Our revenues and profitability are likely to decline significantly during periods of stagnant economic conditions or low trading volume in the U.S. and global financial markets.

Decreases in trading volumes in the fixed-income markets generally or on our platform would harm our business and profitability.

We have experienced significant decreases in overall trading volume in the past and may experience similar decreases in trading volume in the future. Declines in the overall volume of fixed-income securities trading and in market liquidity generally, as well as declines in interest rate volatility, could result in lower revenues from commissions for trades executed on our electronic trading platform and fees generated from related activities.

Likewise, decreases in our share of the segments of the fixed-income trading markets in which we operate, or shifts in trading volume to segments of clients which we have not penetrated, could result in lower trading volume on our platform and, consequently, lower commissions and other revenue. During periods of increased volatility in credit markets, the use of electronic trading platforms by market participants may decrease dramatically as institutional investors seek to obtain additional information during the trade process through conversations with broker-dealers. In addition, during rapidly moving markets, broker-dealers are less likely to post prices electronically.

A decline in trading volumes on our platform for any reason would negatively affect our commission revenue and may have a material adverse effect on our business, financial condition and results of operations.

-22-

Table of Contents

We face substantial competition that could reduce our market share and harm our financial performance.

The fixed-income securities industry generally, and the electronic financial services markets in which we operate in particular, are highly competitive, and we expect competition to intensify in the future. We will continue to compete with bond trading conducted directly between broker-dealers and their institutional investor clients over the telephone or electronically. In addition, our current and prospective competitors are numerous and include:

Many of our current and potential competitors are more established and substantially larger than we are and have substantially greater market presence, as well as greater financial, technical, marketing and other resources. These competitors may aggressively reduce their pricing to enter into market segments in which we have a leadership position today, potentially subsidizing any losses with profits from trading in other fixed-income or equity securities. In addition, many of our competitors offer a wider range of services, have broader name recognition and have larger customer bases than we do. Some of them may be able to respond more quickly to new or evolving opportunities, technologies and customer requirements than we can and may be able to undertake more extensive promotional activities.

Any combination of our competitors may enter into joint ventures or consortia to provide services similar to those provided by us. Current and new competitors can launch new platforms at a relatively low cost. Others may acquire the capabilities necessary to compete with us through acquisitions. We expect that we will potentially compete with a variety of companies with respect to each product or service we offer. If we are not able to compete successfully in the future, our business, financial condition and results of operations would be adversely affected.

Neither the sustainability of our current level of business nor any future growth can be assured. Even if we do experience growth, we cannot assure you that we will grow profitably.

The success of our business strategy depends, in part, on our ability to maintain and expand the network of broker-dealer and institutional investor clients that use our electronic trading platform. Our business strategy also depends on increasing the use of our platform by these clients. Individuals at broker-dealers or institutional investors may have conflicting interests, which may discourage their use of our platform.

Our growth is also dependent on our ability to diversify our revenue base. We currently derive approximately 60% of our revenues from secondary trading in U.S. high-grade corporate bonds. Our long-term business strategy is dependent on expanding our service offerings and increasing our revenues from other fixed-income products and other sources. We cannot assure you that our efforts will be successful or result in increased revenues or continued profitability. We have experienced significant growth in trading volumes, revenues and profitability over the past three years. We cannot assure you that our business will continue to grow at a similar rate, if at all.

Because we operate in a rapidly evolving industry, it is difficult to evaluate our business and prospects.

We face risks and difficulties frequently experienced by companies operating in rapidly evolving industries, such as the electronic financial services industry. These risks and difficulties include, but are not limited to, our ability to:

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 may enter into new fee plans, the impact of which may be difficult to evaluate.

From time to time we have and may introduce new fee plans for the U.S. high-grade corporate bond, Eurobond and other market segments in which we operate. Any new fee plan may include different fee structures or provide volume incentives. We cannot assure you that any new fee plans will result in an increase in the volume of transactions effected on our platform or that our revenues will increase as a result of the implementation of any such fee plans. It is possible that our broker-dealer or institutional investor clients could respond to a new fee plan by either reducing the amount of their business conducted on our platform or terminating their contractual relationship with us, which could have an adverse impact on our fees and otherwise have a material adverse effect on our business, financial condition and results of operations.

We are exposed to risks resulting from non-performance by counterparties to certain transactions executed between our clients in which we act as an intermediary in matching back-to back bond trades.

We execute certain bond transactions between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller in matching back-to-back trades, which are then settled through a third-party clearing organization. MarketAxess Corporation, our U.S. subsidiary, and MarketAxess Europe Limited, our U.K. subsidiary, act as intermediary on a riskless principal basis in these bond transactions by serving as counterparty to the two clients involved. Settlement typically occurs within one to three trading days after the trade date. Cash settlement of the transaction occurs upon receipt or delivery of the underlying instrument that was traded.

We are exposed to credit risk in our role as trading counterparty to our clients executing bond trades on our platform. We are exposed to the risk that third parties that owe us money, securities or other assets will not perform their obligations. These parties may default on their obligations to us due to bankruptcy, lack of liquidity, operational failure or other reasons. Adverse movements in the prices of securities that are the subject of these transactions can increase our risk. Where the unmatched position or failure to deliver is prolonged there may also be regulatory capital charges required to be taken by us. There can be no assurance that the policies and procedures we use to manage this credit risk will effectively mitigate our credit risk exposure.

-24-

Table of Contents

We have policies and procedures in place to identify and manage our credit risk. There can be no assurance that the policies and procedures we use to manage this credit risk will effectively mitigate our credit risk exposure. Some of our risk management procedures are reliant upon the evaluation of information regarding the fixed income markets, our clients or other relevant matters that are publicly available or otherwise acquired from third party sources. Such information may not be accurate, complete, or properly assessed and interpreted by us. If our risk management procedures fail, our business, financial condition and results of operations may be adversely affected. Furthermore, our insurance policies may not provide full protection from such risk.

We are dependent on our broker-dealer clients, who are not restricted from buying and selling fixed-income securities, directly or through their own proprietary or third-party platforms, with institutional investors.

We rely on our broker-dealer clients to provide product and liquidity on our electronic trading platform by posting bond prices on our platform for bonds in their inventory and responding to institutional investor client inquiries. The contractual obligations of our broker-dealer clients to us are minimal, non-exclusive and terminable by such clients. Our broker-dealer clients buy and sell fixed-income securities through traditional methods, including by telephone and e-mail messaging, and through other electronic trading platforms. Some of our broker-dealer clients have developed electronic trading networks that compete with us or have announced their intention to explore the development of such electronic trading networks, and most of our broker-dealer and institutional investor clients are involved in other ventures, including other electronic trading platforms or other distribution channels, as trading participants and/or as investors. These competing trading platforms may offer some features that we do not currently offer. Accordingly, there can be no assurance that such broker-dealers’ primary commitments will not be to one of our competitors. In addition, there has been significant consolidation among firms in the banking and financial services industries over the past several years. Further consolidation, instability, and layoffs in the financial services industry could result in a smaller client base and heightened competition.

Any reduction in the use of our electronic trading platform by our broker-dealer clients could reduce the number of different bond issues and the volume of trading in those bond issues on our platform, which could, in turn, reduce the use of our platform by our institutional investor clients. The occurrence of any of the foregoing may have a material adverse effect on our business, financial condition and results of operations.

We could lose significant sources of revenue and trading volume if we lose any of our significant institutional investor clients.

We rely on our institutional investor clients to launch inquiries over our trading platform. A limited number of such clients can account for a significant portion of our trading volume. One institutional investor client accounted for approximately 13.5%, 14.6% and 15.8% of trading volumes during the years ended December 31, 2012, 2011 and 2010, respectively. This institutional investor client also beneficially owns approximately 7% of the outstanding shares of our common stock. The contractual obligations of our institutional investor clients to us are minimal, non-exclusive and terminable by such clients. Our institutional investor clients buy and sell fixed-income securities through traditional methods, including by telephone and e-mail messaging, and through other electronic trading platforms.

There can be no assurance that we will be able to retain our major institutional investor clients or that such clients will continue to use our trading platform. The loss of any major institutional investor client or any reduction in the use of our electronic trading platform by such clients could have a material adverse effect on our business, financial condition and results of operations.

If we experience significant fluctuations in our operating results or fail to meet revenue and earnings expectations, our stock price may fall rapidly and without advance notice.

Our revenues and operating results may fluctuate due to a number of factors, including:

-25-

Table of Contents

As a result, our operating results may fluctuate significantly on a quarterly basis, which could result in decreases in our stock price.

We may not be able to introduce enhanced versions of our electronic trading platform, new services and/or service enhancements in a timely or acceptable manner, which could harm our competitive position.

Our business environment is characterized by rapid technological change, changing and increasingly sophisticated client demands and evolving industry standards. Our future will depend on our ability to develop and introduce new features to, and new versions of, our electronic trading platform. The success of new features and versions depends on several factors, including the timely completion, introduction and market acceptance of the feature or version. In addition, the market for our electronic trading platform may be limited if prospective clients require customized features or functions that we are unable or unwilling to provide. If we are unable to anticipate and respond to the demand for new services, products and technologies and develop new features and enhanced versions of our electronic trading platform that achieve widespread levels of market acceptance on a timely and cost-effective basis, it could have a material adverse effect on our business, financial condition and results of operations.

As we enter new markets, we may not be able to successfully attract clients and adapt our technology and marketing strategy for use in those markets.

Our strategy includes leveraging our electronic trading platform to enter new markets. We cannot assure you that we will be able to successfully adapt our proprietary software and technology for use in other markets. Even if we do adapt our software and technology, we cannot assure you that we will be able to attract clients and compete successfully in any such new markets. We cannot assure you that our marketing efforts or our pursuit of any of these opportunities will be successful. If these efforts are not successful, we may realize less than expected earnings, which in turn could result in a decrease in the market value of our common stock. Furthermore, these efforts may divert management attention or inefficiently utilize our resources.

Rapid market or technological changes may render our technology obsolete or decrease the attractiveness of our products and services to our broker-dealer and institutional investor clients.

We must continue to enhance and improve our electronic trading platform. The electronic financial services industry is characterized by significant structural changes, increasingly complex systems and infrastructures, changes in clients’ needs and preferences and new business models. If new industry standards and practices emerge and our competitors release new technology before us, our existing technology, systems and electronic trading platform may become obsolete or our existing business may be harmed. Our future success will depend on our ability to:

-26-

Table of Contents

Developing our electronic trading platform and other technology entails significant technical and business risks. We may use new technologies ineffectively or we may fail to adapt our electronic trading platform, information databases and network infrastructure to broker-dealer or institutional investor client requirements or emerging industry standards. For example, our electronic trading platform functionality that allows searches and inquiries on bond pricing and availability is a critical part of our service, and it may become out-of-date or insufficient from our broker-dealer clients’ or institutional investor clients’ perspective and in relation to the inquiry functionality of our competitors’ systems. If we face material delays in introducing new services, products and enhancements, our broker-dealer and institutional investor clients may forego the use of our products and use those of our competitors.

Further, the adoption of new Internet, networking or telecommunications technologies may require us to devote substantial resources to modify and adapt our services. We cannot assure you that we will be able to successfully implement new technologies or adapt our proprietary technology and transaction-processing systems to client requirements or emerging industry standards. We cannot assure you that we will be able to respond in a timely manner to changing market conditions or client requirements.

We depend on third-party suppliers for key products and services.

We rely on a number of third parties to supply elements of our trading, information and other systems, as well as computers and other equipment, and related support and maintenance. We cannot assure you that any of these providers will be able to continue to provide these services in an efficient, cost-effective manner, if at all, or that they will be able to adequately expand their services to meet our needs. If we are unable to make alternative arrangements for the supply of critical products or services in the event of a malfunction of a product or an interruption in or the cessation of service by an existing service provider, our business, financial condition and results of operations could be materially adversely affected.

In particular, we depend on a third-party vendor for our corporate bond reference database. Disruptions in the services provided by that third party to us, including as a result of their inability or unwillingness to continue to license products that are critical to the success of our business, could have a material adverse effect on our business, financial condition and results of operations.

We also rely, and expect in the future to continue to rely, on third parties for various computer and communications systems, such as telephone companies, online service providers, data processors, and software and hardware vendors. Other third parties provide, for instance, our data center, telecommunications access lines and significant computer systems and software licensing, support and maintenance services. Any interruption in these or other third-party services or deterioration in their performance could impair the quality of our service. We cannot be certain of the financial viability of all of the third parties on which we rely.

We license software from third parties, much of which is integral to our electronic trading platform and our business. We also hire contractors to assist in the development, quality assurance testing and maintenance of our electronic trading platform and other systems. Continued access to these licensors and contractors on favorable contract terms or access to alternative software and information technology contractors is important to our operations. Adverse changes in any of these relationships could have a material adverse effect on our business, financial condition and results of operations.

We attempt to negotiate favorable pricing, service, confidentiality and intellectual property ownership or licensing and other terms in our contracts with our service providers. These contracts usually have multi-year terms. However, there is no guarantee that these contracts will not terminate and that we will be able to negotiate successor agreements or agreements with alternate service providers on competitive terms. Further, the existing agreements may bind us for a period of time to terms and technology that become obsolete as our industry and our competitors advance their own operations and contracts.

Our success depends on maintaining the integrity of our electronic trading platform, systems and infrastructure; our computer systems may suffer failures, capacity constraints and business interruptions that could increase our operating costs and cause us to lose clients.

In order to be successful, we must provide reliable, secure, real-time access to our electronic trading platform for our broker-dealer and institutional investor clients. If our electronic trading platform is hampered by slow delivery times, unreliable service or insufficient capacity, our broker-dealer and institutional investor clients may decide to stop using our platform, which would have a material adverse effect on our business, financial condition and results of operations.

Table of Contents

As our operations grow in both size and scope, we will need to improve and upgrade our electronic trading platform and infrastructure to accommodate potential increases in order message volume and trading volume, the trading practices of new and existing clients, regulatory changes and the development of new and enhanced trading platform features, functionalities and ancillary products and services. The expansion of our electronic trading platform and infrastructure has required, and will continue to require, substantial financial, operational and technical resources. These resources will typically need to be committed well in advance of any actual increase in trading volumes and order messages. We cannot assure you that our estimates of future trading volumes and order messages will be accurate or that our systems will always be able to accommodate actual trading volumes and order messages without failure or degradation of performance. Furthermore, we use new technologies to upgrade our established systems, and the development of these new technologies also entails technical, financial and business risks. We cannot assure you that we will successfully implement new technologies or adapt our existing electronic trading platform, technology and systems to the requirements of our broker-dealer and institutional investor clients or to emerging industry standards. The inability of our electronic trading platform to accommodate increasing trading volume and order messages would also constrain our ability to expand our business.

We cannot assure you that we, or our third party service providers, will not experience systems failures. Our electronic trading platform, computer and communication systems and other operations are vulnerable to damage, interruption or failure as a result of, among other things:

In the event that any of our systems, or those of our third-party providers, fail or operate slowly, it may cause any one or more of the following to occur:

Any system failure that causes an interruption in service or decreases the responsiveness of our service, including failures caused by client error or misuse of our systems, could damage our reputation, business and brand name and lead our broker-dealer and institutional investor clients to decrease or cease their use of our electronic trading platform.

-28-

Table of Contents

In these circumstances, our redundant systems or disaster recovery plans may not be adequate. Similarly, although many of our contracts with our service providers require them to have disaster recovery plans, we cannot be certain that these will be adequate or implemented properly. In addition, our business interruption insurance may not adequately compensate us for losses that may occur.

We also cannot assure you that we have sufficient personnel to properly respond to system problems. We internally support and maintain many of our computer systems and networks, including those underlying our electronic trading platform. Our failure to monitor or maintain these systems and networks or, if necessary, to find a replacement for this technology in a timely and cost-effective manner would have a material adverse effect on our business, financial condition and results of operations.

Our systems and those of our third party service providers may be vulnerable to cybersecurity risks. If our security measures are breached and unauthorized access is obtained to our electronic trading platform, our business could suffer a material adverse effect.

Our electronic trading platform involves the storage and transmission of our clients’ proprietary information. The secure storage and transmission of confidential information over public networks is a critical element of our operations. Cyber attacks on our systems or the systems of our third party service providers could expose us to a risk of misappropriation of this information, leading to litigation and possible liability. If our security measures are breached as a result of third-party action, employee error, malfeasance or otherwise, and, as a result, someone obtains unauthorized access to trading or other confidential information, our reputation could be damaged, our business may suffer and we could incur significant liability. Any such breach could compromise our networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Because techniques used to obtain unauthorized access or to sabotage computer systems change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventive measures. Any cybersecurity breach may have a material adverse effect on our business, financial condition and results of operations. A cyber attack or security breach on our system or that of a third party service provider could manifest in different ways and could lead to any number of harmful consequences, including but not limited to:

Our remediation costs and lost revenues could be significant if we fall victim to a cyber attack. If an actual, threatened or perceived breach of our security occurs, the market perception of the effectiveness of our security measures could be harmed and could cause our broker-dealer and institutional investor clients to reduce or stop their use of our electronic trading platform. We may be required to expend significant resources to repair system damage, protect against the threat of future security breaches or to alleviate problems, including reputational harm, loss of clients and revenues and litigation, caused by any breaches. We may be found liable to our clients for any stolen assets or misappropriated confidential information. Although we intend to continue to implement industry-standard security measures, we cannot assure you that those measures will be sufficient.

We may not be able to protect our intellectual property rights or technology effectively, which would allow competitors to duplicate or replicate our electronic trading platform. This could adversely affect our ability to compete.

Intellectual property is critical to our success and ability to compete, and if we fail to protect our intellectual property rights adequately, our competitors might gain access to our technology. We rely primarily on a combination of patent, copyright, trademark and trade secret laws in the United States and other jurisdictions, as well as license agreements, third-party non-disclosure and other agreements and other contractual provisions and technical measures to protect our intellectual property rights. We attempt to negotiate beneficial intellectual property ownership provisions in our contracts and also require employees, consultants, advisors and collaborators to enter into confidentiality agreements in order to protect the confidentiality of our proprietary information. We have received 11 patents and have filed patent applications covering aspects of our technology and/or business, but can give no assurances that any such patents will protect our business and processes from competition or that the patents applied for will be issued. Additionally, laws and our contractual terms may not be sufficient to protect our technology from use or theft by third parties. For instance, a third party might reverse engineer or otherwise obtain and use our technology without our permission and without our knowledge, thereby infringing our rights and allowing competitors to duplicate or replicate our products. Furthermore, we cannot assure you that these protections will be adequate to prevent our competitors from independently developing technologies that are substantially equivalent or superior to our technology.

-29-

Table of Contents

We may have legal or contractual rights that we could assert against illegal use of our intellectual property rights, but lawsuits claiming infringement or misappropriation are complex and expensive, and the outcome would not be certain. In addition, the laws of some countries in which we now or in the future provide our services may not protect software and intellectual property rights to the same extent as the laws of the United States.

Defending against intellectual property infringement or other claims could be expensive and disruptive to our business. If we are found to infringe the proprietary rights of others, we could be required to redesign our products, pay royalties or enter into license agreements with third parties.

In the technology industry, there is frequent litigation based on allegations of infringement or other violations of intellectual property rights. As the number of participants in our market increases and the number of patents and other intellectual property registrations increases, the possibility of an intellectual property claim against us grows. Although we have never been the subject of a material intellectual property dispute, we cannot assure you that a third party will not assert in the future that our technology or the manner in which we operate our business violates its intellectual property rights. From time to time, in the ordinary course of our business, we may become subject to legal proceedings and claims relating to the intellectual property rights of others, and we expect that third parties may assert intellectual property claims against us, particularly as we expand the complexity and scope of our business, the number of electronic trading platforms increases and the functionality of these platforms further overlaps. Any claims, whether with or without merit, could:

We cannot assure you that third parties will not assert infringement claims against us in the future with respect to our electronic trading platform or any of our other current or future products or services or that any such assertion will not require us to cease providing such services or products, try to redesign our products or services, enter into royalty arrangements, if available, or engage in litigation that could be costly to us. Any of these events could have a material adverse effect on our business, financial condition and results of operations.

If we acquire or invest in other businesses, products or technologies, we may be unable to integrate them with our business, our financial performance may be impaired or we may not realize the anticipated financial and strategic goals for any such transactions.

We have in the past and may in the future acquire or invest in companies, products or technologies that we believe are strategic. On October 26, 2012, we entered into an agreement to acquire all of the outstanding shares of Xtrakter. We may not be able to identify, negotiate or finance any future acquisition or investment successfully. Even if we do succeed in acquiring or investing in a business, product or technology, such acquisitions and investments, including the pending Xtrakter acquisition, may involve a number of risks, including:

-30-

Table of Contents

These factors could have a material adverse effect on our business, financial condition, results of operations and cash flows, particularly in the case of a larger acquisition or multiple acquisitions in a short period of time. From time to time, we may enter into negotiations for acquisitions or investments that are not ultimately consummated. Such negotiations could result in significant diversion of management time, as well as out-of-pocket costs.

-31-

Table of Contents

The consideration paid in connection with an investment or acquisition also affects our financial results. If we were to proceed with one or more significant acquisitions in which the consideration included cash, we could be required to use a substantial portion of our available cash to consummate any acquisition. To the extent we issue shares of capital stock or other rights to purchase capital stock, including options or other rights, existing stockholders may be diluted and earnings per share may decrease. In addition, acquisitions may result in the incurrence of debt, large one-time write-offs, such as of acquired in-process research and development costs, and restructuring charges.

We may be required to recognize impairments of our goodwill or other intangible assets, which could adversely affect our results of operations or financial condition.

The determination of the value of goodwill and other intangible assets requires management to make estimates and assumptions that affect our consolidated financial statements. We test for impairment of goodwill on an annual basis or more frequently if there are changed circumstances. We assess intangible assets for impairment when events or circumstances indicate the existence of a possible impairment.

Determining the fair value of certain assets acquired and liabilities assumed is judgmental in nature and requires management to use significant estimates and assumptions, including assumptions with respect to future cash flows, discount rates, growth rates and asset lives. Any future acquisition may result in goodwill and other intangible assets that are subject to impairment tests, which could result in future impairment charges.

We are dependent on our management team, and the loss of any key member of this team may prevent us from implementing our business plan in a timely manner.

Our success depends largely upon the continued services of our executive officers and other key personnel, particularly Richard M. McVey, Chief Executive Officer and Chairman of our Board of Directors. The terms of Mr. McVey’s employment agreement with us do not require him to continue to work for us and allow him to terminate his employment at any time, subject to certain notice requirements and forfeiture of non-vested equity compensation awards. Any loss or interruption of Mr. McVey’s services or that of one or more of our other executive officers or key personnel could result in our inability to manage our operations effectively and/or pursue our business strategy.

Because competition for our employees is intense, we may not be able to attract and retain the highly skilled employees we need to support our business.

We strive to provide high-quality services that will allow us to establish and maintain long-term relationships with our broker-dealer and institutional investor clients. Our ability to provide these services and maintain these relationships, as well as our ability to execute our business plan generally, depends in large part upon our employees. We must attract and retain highly qualified personnel. Competition for these personnel is intense, especially for software engineers with extensive experience in designing and developing software and Internet-related services, hardware engineers, technicians, product managers and senior sales executives.

The market for qualified personnel is increasingly competitive as the financial industry continues to recover from the financial crisis and as electronic commerce continues to experience strong growth. Many of the companies with which we compete for experienced personnel have greater resources than we have and are longer established in the marketplace. In addition, in making employment decisions, particularly in the Internet, high-technology and financial services industries, job candidates often consider the total compensation package offered, including the value of the stock-based compensation they are to receive in connection with their employment. Significant volatility in the price of our common stock may adversely affect our ability to attract or retain key employees. The expensing of stock-based compensation may discourage us from granting the size or type of stock-based compensation that job candidates may require to join our company.

We cannot assure you that we will be successful in our efforts to recruit and retain the required personnel. The failure to attract new personnel or to retain and motivate our current personnel may have a material adverse effect on our business, financial condition and results of operations.

Table of Contents

Our business is subject to increasingly extensive government and other regulation and our relationships with our broker-dealer clients may subject us to increasing regulatory scrutiny, which may affect our trading volumes and increase our cost of doing business.

The financial industry is extensively regulated by many governmental agencies and self-regulatory organizations, including the SEC and FINRA. As a matter of public policy, these regulatory bodies are responsible for safeguarding the integrity of the securities and other financial markets and protecting the interests of investors in those markets. These regulatory bodies have broad powers to promulgate and interpret, investigate and sanction non-compliance with their laws, rules and regulations.

Most aspects of our broker-dealer subsidiaries are highly regulated, including:

We cannot assure you that we and/or our directors, officers and employees will be able to fully comply with these laws, rules and regulations. If we fail to comply with any of these laws, rules or regulations, we may be subject to censure, fines, cease-and-desist orders, suspension of our business, suspensions of personnel or other sanctions, including revocation of our membership in FINRA and registration as a broker-dealer.

We have two major operating subsidiaries, MarketAxess Corporation and MarketAxess Europe Limited. MarketAxess Corporation and MarketAxess Europe Limited are subject to U.S. and U.K. regulations as a registered broker-dealer and as a multilateral trading facility, respectively, which prohibit repayment of borrowings from the Company or affiliates, paying cash dividends, making loans to the Company or affiliates or otherwise entering into transactions that result in a significant reduction in regulatory net capital or financial resources, without prior notification to or approval from such subsidiary’s principal regulator. Xtrakter is registered, and upon consummation of the pending acquisition will continue to be registered, as an Approved Reporting Mechanism with the FSA. Xtrakter also has “recognized status” in France, the Netherlands and Belgium in connection with the submission of transaction reports to regulators.

In addition, as a result of the global financial crisis and other recent events in the financial industry, there is a greater likelihood of legislative and regulatory action to increase government oversight of the financial services industry. For example, during 2010 the Dodd-Frank Act was signed into law. The Dodd-Frank Act creates an entirely new structure for the trading of over-the-counter derivatives, a market in which we currently operate. Among other things, the Dodd-Frank Act mandates that clearable swaps trade on a board of trade designated as a contract market or a securities exchange or through a “swap execution facility,” or SEF (in each case, subject to certain key exceptions). While we expect that the CFTC and SEC will adopt rules that detail the new regulatory regime regarding the swaps market place in 2013, no assurance can be given regarding when, or whether, such rules will be finalized and implemented. Subject to such rulemaking, we intend to establish, register and operate a swap execution facility and/or a security-based swap execution facility.

We have incurred significant costs to prepare for compliance with the new regulatory requirements. We developed new technology and trading protocols to trade CDS in anticipation of the SEC and CFTC’s implementation of the Dodd-Frank Act. However, despite our efforts, there is no assurance that we will qualify as a registered SEF or that our compliance systems will be effective. If we do not qualify as a SEF, we will no longer be able to support CDS trades and our business, financial condition and results of operations could materially suffer as a result. If we qualify as a SEF, the registration and additional oversight that we will need to comply with the regulation will increase the costs of our operations and the costs of using our products for our clients. Furthermore, we are unable to predict how the markets will respond to the new regulatory regime.

-33-

Table of Contents

Any changes in laws or regulations or in governmental policies, including the rules relating to the maintenance of specific levels of net capital applicable to our broker-dealer subsidiaries, could have a material adverse effect on our business, financial condition and results of operations. Our industry has been and is subject to continuous regulatory changes and may become subject to new regulations or changes in the interpretation or enforcement of existing regulations, which could require us to incur significant compliance costs or cause the development of affected markets to become impractical. In addition, as we expand our business into new markets, it is likely that we will be subject to additional laws, rules and regulations. The proposed Volcker Rule section of the Dodd-Frank Act bans proprietary trading by banks and their affiliates. The Volcker Rule could adversely affect our bank-affiliated broker-dealer clients’ ability to make markets in a variety of fixed-income securities, thereby negatively impacting the level of liquidity and pricing available on our trading platform. We cannot predict the extent to which any future regulatory changes may adversely affect our business and operations.

Our disclosed trading system has not been subjected to regulation as an alternative trading system under Regulation ATS. A determination by the SEC to treat our trading platform as an alternative trading system subject to Regulation ATS would subject us to additional reporting obligations and other limitations on the conduct of our business, many of which could be material. Our anonymous dealer-to-dealer trading service, DealerAxess^®, is regulated as an alternative trading system subject to Regulation ATS.

The activities and consequences described above may result in significant distractions to our management and could have a material adverse effect on our business, financial condition and results of operations.

We may face increasing economic and regulatory challenges in our growing international operations that we may not be able to meet in the future.

We operate an electronic trading platform in Europe and we plan to further expand our operations throughout Europe and other regions. There are certain risks inherent in doing business in international markets, particularly in the financial services industry, which is heavily regulated in many jurisdictions. These risks include:

Our international operations are also subject to the legal, economic and market risks associated with geopolitical uncertainties in other regions of the world, including but not limited to the risk of war, inter and intra national conflict, economic crises and terrorism. For example, the sovereign debt crisis in Europe may have a material adverse effect on our business. Increased government deficits and debt levels along with ratings downgrades sparked fears in the global financial markets of default by Euro zone nations, leading to increased yields on government bonds and resulting in a more difficult trading environment for European corporate bonds. Due, in part, to the crisis and competitive environment in Europe, trading volume in our Eurobond product has significantly decreased. We reduced the monthly distribution fees paid by our European broker-dealer market makers effective March 1, 2012 in order to encourage Eurobond trading, which resulted in decreased monthly distribution fee revenues. Despite our efforts, Eurobond trading volumes continued to decline. There is no assurance that Eurobond trading volumes and revenues will not continue to decline despite this change and any other efforts we may undertake.

Table of Contents

In addition, we must comply with the laws, regulations and registration rules of the Financial Services Authority in the U.K. and foreign governments and regulatory bodies for each country in which we conduct business. Similar to the U.S., regulatory bodies in Europe and elsewhere are developing new rules for derivatives trading. For example, the European Parliament and the EU Council of Ministers endorsed an agreement that will, among other things, require central clearing of standardized OTC derivatives and the reporting of all derivatives (OTC or otherwise) to trade repositories. However, it is not yet clear whether there will be any requirement in the EU to trade standardized CDS contracts on regulated exchanges or trading platforms.

We cannot predict what future actions the U.S., U.K. and other regulatory bodies might take, or the impact that any such actions may have on our business. Our compliance with these changing laws and regulations may be costly and time-consuming and may have a material adverse effect on our clients’ trading activities on our platform.

Further, we may face unexpected challenges in our international operations due to global competitors, established local markets, and economic and political instability. Our inability to manage these risks effectively could adversely affect our business and limit our ability to expand our international operations, which could have a material adverse effect on our business, financial condition and results of operations.

We cannot assure you that our compliance and risk management methods will be effective and our financial condition and results of operations may be adversely affected if they fail.

Our success in complying with complex and changing laws and navigating risks in various jurisdictions and markets depends on our maintenance of compliance, auditing and reporting systems and risk management procedures, as well as our ability to recruit and retain qualified compliance and risk management personnel. While we have developed policies and procedures to identify, monitor and manage our legal, regulatory and market risks, we cannot assure you that our systems will always be effective in monitoring or evaluating the risks to which we are exposed.

In addition, the regulators in the jurisdictions in which we operate have broad powers to censure, fine, issue cease-and-desist orders or keep us from engaging in some of our operations. We face the risk of regulatory intervention, investigations and proceedings, any of which could involve extensive scrutiny of our activities and result in significant fines and liability. Any of these developments would require significant time and financial resources and could adversely affect our reputation, financial condition and operating results.

Our growth initiatives may place significant strain on management and other resources.

We have expanded our business activities and operations over the last several years. Continued growth, both domestic and international, will require further investment in management and new personnel, infrastructure and compliance systems. The expansion of our international operations involves risks that may have an adverse effect on our business and operations, such as the challenge of effectively managing and staffing our international operations, complying with increased and varied regulatory requirements and entering new markets. In particular, we may not be successful in implementing all of the necessary processes to support and manage the pending Xtrakter acquisition. For a detailed discussion of the risks associated with our pending acquisition of Xtrakter, see the Risk Factor captioned “If we acquire or invest in other businesses, products or technologies, we may be unable to integrate them with our business, our financial performance may be impaired or we may not realize the anticipated financial and strategic goals for any such transactions.”

We may not be able to manage our growth efficiently, which could result in our expansion costs increasing at a faster rate than our revenues and distracting management from our core business and operations. If we cannot successfully implement the necessary processes to support and manage new initiatives, our business, financial condition and results of operations may suffer.

In the event of employee error or misconduct, our business may be harmed.

Employee misconduct or error could expose us to significant liability, financial losses, regulatory sanctions and reputational harm. Over the past few years, there have been several high-profile cases involving fraud or misconduct by employees of financial services firms. Our employees could carry out improper activities on behalf of our clients, or use proprietary client or company information for personal or other improper or illegal uses. Employee errors also expose us to the risk of material loss until such errors are detected and unauthorized transactions or improper activities are reversed.

Errors and misconduct by our current or former employees could cause us to suffer financial losses, regulatory sanctions and reputational harm. The precautions we take to monitor and prevent employee errors and misconduct may not be effective in all cases.

We cannot predict our future capital needs or our ability to obtain additional financing if we need it.

Our business is dependent upon the availability of adequate funding and regulatory capital under applicable regulatory requirements. Although we believe that our available cash resources and borrowing capacity under our credit facility are sufficient to meet our presently anticipated liquidity needs and capital expenditure requirements for at least the next 12 months, we may in the future need to raise additional funds to, among other things:

We expect that debt financing, if available at all, would likely be pursuant to the terms of our credit agreement with JPM, which includes restrictive covenants with respect to dividends, issuances of additional capital and other financial and operational matters related to our business. For a detailed discussion of the risks associated with our credit agreement, see the Risk Factor captioned “Our credit agreement contains restrictive and financial covenants that limit our operating flexibility, and we may incur additional debt in the future that may include similar or additional restrictions.”

In the future, we may not be able to obtain additional financing, if needed, in amounts or on terms acceptable to us, if at all. If sufficient funds are not available or are not available on terms acceptable to us, our ability to fund our expansion, take advantage of acquisition opportunities, develop or enhance our services or products, or otherwise respond to competitive pressures would be significantly limited. These limitations could have a material adverse effect on our business, financial condition and results of operations.

Our credit agreement contains restrictive and financial covenants that could limit our operating flexibility, and we may incur additional debt in the future that may include similar or additional restrictions.

We are party to a credit agreement with JPMorgan that provides for revolving loans and letters of credit up to an aggregate of $50.0 million. Subject to satisfaction of certain specified conditions, we are permitted to upsize the credit agreement by an additional $50.0 million in total. Our credit agreement contains certain covenants that, among other things, restrict our ability to take certain actions, even if we believe them to be in our best interests. These covenants restrict or prohibit, among other things, our ability to:

Table of Contents

We are also required by our credit agreement to maintain a maximum consolidated leverage ratio and a minimum consolidated interest coverage ratio. We cannot assure you that we will be able to meet these requirements or satisfy these covenants in the future. A breach of any of these covenants or the inability to comply with the required financial covenants could result in an event of default under the credit agreement. If any such event of default occurs, the lender under the credit agreement could elect to declare all amounts outstanding and accrued and unpaid interest under the credit agreement to be immediately due and payable, and could foreclose on the assets securing the credit agreement. The lender would also have the right in these circumstances to terminate any commitments it has to provide further credit extensions. We may incur other indebtedness in the future that may contain financial or other covenants more restrictive than those applicable to the credit agreement.

We are subject to the risks of litigation and securities laws liability.

Many aspects of our business, and the businesses of our clients, involve substantial risks of liability. Dissatisfied clients may make claims regarding quality of trade execution, improperly settled trades, mismanagement or even fraud against their service providers. We and our clients may become subject to these claims as the result of delays, failures or malfunctions of our electronic trading platform and services provided by us. We could incur significant legal expenses defending claims, even those without merit. An adverse resolution of any lawsuits or claims against us could have a material adverse effect on our business, financial condition and results of operations.

If the use of electronic trading platforms does not increase, we may not be able to achieve our business objectives.

The success of our business plan depends in part on our ability to create an electronic trading platform for a wide range of fixed-income products. Historically, fixed-income securities markets operated through telephone communications between institutional investors and broker-dealers. The utilization of our products and services depends on the acceptance, adoption and growth of electronic means of trading securities. We cannot assure you that the growth and acceptance of electronic means of trading securities will continue.

Fluctuations in foreign currency exchange rates may adversely affect our financial results.

We conduct operations in several different countries, including the U.S. and the U.K., and substantial portions of our revenues, expenses, assets and liabilities are denominated in U.S. dollars, pounds sterling and euros. Since our consolidated financial statements are presented in U.S. dollars, we must translate revenues, income and expenses, as well as assets and liabilities, into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Accordingly, increases or decreases in the value of the U.S. dollar against the other currencies will affect our net operating revenues, operating income and the value of balance sheet items denominated in foreign currencies.

Although we have entered into foreign currency forward contracts to hedge the exposure to variability in foreign currency cash flows and may enter into additional hedging transactions in the future to help mitigate our foreign exchange risk exposure, these hedging arrangements may not be effective, particularly in the event of inaccurate forecasts of the levels of our non-U.S. denominated assets and liabilities. Accordingly, if there are adverse movements in exchange rates, we may suffer significant losses, which would adversely affect our operating results and financial condition.

As a public company, we are subject to certain financial and corporate governance requirements that may be difficult for us to satisfy and may divert management’s attention from our business.

We are subject to the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (“SOX”) and the related SEC rules and regulations that call for our management to conduct an annual assessment and report on the effectiveness of our internal controls over financial reporting. Our independent registered public accounting firm must also issue an annual report addressing the operating effectiveness of the Company’s internal controls over financial reporting.

-37-

Table of Contents

While our internal controls over financial reporting currently meet the standards set forth in SOX, failure to maintain an effective internal control environment could have a material adverse effect on our business, financial condition and results of operations. We cannot be certain of our ability to continue to comply with the requirements of SOX. If we are unable to continue to comply with the requirements of SOX in an efficient manner, we may be subject to regulatory action. In addition, in the event that we identify a material weakness, there can be no assurance that we would be able to remediate such material weakness in an efficient manner. Moreover, if we are unable to assert that our internal control over financial reporting is effective in any future period (or if our auditors are unable to issue an opinion on the effectiveness of our internal controls), we could suffer reputational harm and incur significant expenses to restructure our internal controls over financial reporting, which may have a material adverse effect on us.

Risks Related to Our Common Stock

Market volatility and future sales of our shares by significant stockholders may cause our stock price and the value of your investment to decline.

The market price of our common stock may be significantly affected by volatility in the markets in general. The market price of our common stock likely will continue to fluctuate in response to factors including the following:

Most of these factors are beyond our control. In addition, the stock markets in general, including the NASDAQ Global Select Market, have experienced and continue to experience significant price and volume fluctuations. These fluctuations have resulted in volatility in the market prices of securities for companies such as ours that often has been unrelated or disproportionate to changes in the operating performance of the affected companies. These broad market and industry fluctuations may affect adversely the market price of our common stock regardless of our operating performance.

In addition, future sales of our common stock, or the perception of potential future sales, may adversely impact the market price of our common stock. If any one or more of our existing stockholders were to sell a large number of shares, the market price of our common stock could be negatively affected. Also, if we issue a large number of shares of our common stock in connection with a public offering, future acquisition, strategic alliance, third-party investment and private placement or otherwise, the market price of our common stock could decline considerably. Furthermore, our stockholders may be diluted by such future sales.

We may not pay dividends on our common stock in the future.

We initiated a regular quarterly dividend on our common stock in 2009. However, there is no assurance that we will continue to pay any dividends to holders of our common stock in the future. If we were to cease paying dividends, investors would need to rely on the sale of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment.

If securities analysts do not publish research or reports about our business or if they downgrade our common stock, the price of our common stock could decline.

The trading market for our common stock relies in part on the research and reports that industry or financial analysts publish about us or our business. These analysts work independently of us. If one or more analysts who cover us downgrade our stock, our stock price could decline rapidly. If one or more of these analysts cease coverage of our company, we could lose visibility in the market, which in turn could cause our stock price to decline.

Provisions in our organizational documents 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 common stock.

Provisions of our certificate of incorporation and bylaws may make it substantially more difficult for a third party to acquire control of us and may prevent changes in our management, including provisions that:

Provisions of Delaware law may also inhibit potential acquisition bids for us or prevent us from engaging in business combinations. In addition, we have a severance agreement with one employee and a change of control severance plan that could require an acquiror to pay a higher price. Either collectively or individually, these provisions may prevent holders of our common stock from benefiting from what they may believe are the positive aspects of acquisitions and takeovers, including the potential realization of a higher rate of return on their investment from these types of transactions.

None.

Item 2. Properties.

Our corporate headquarters and principal U.S. offices are located at 299 Park Avenue, New York, New York, where we lease 27,900 square feet under sequential leases expiring in February 2022. We also collectively lease approximately 21,600 square feet for our other office locations in the U.S., United Kingdom, Brazil, Hong Kong and Singapore under various leases expiring between September 2013 and November 2020.

Item 3. Legal Proceedings.

We assess liabilities and contingencies in connection with outstanding legal proceedings, if any, utilizing the latest information available. For matters where it is probable that we will incur a material loss and the amount can be reasonably estimated, we would establish an accrual for the loss. Once established, the accrual would be adjusted to reflect any relevant developments. When a loss contingency is not both probable and estimable, we would not establish an accrual.

On January 2, 2013, a former employee filed a complaint against us with the U.S. Department of Labor alleging retaliatory employment practices in violation of the whistleblower provisions of the Sarbanes-Oxley Act. The relief sought includes, among other things, reinstatement, back pay and compensatory and punitive damages.

We believe the complaint is without merit and we intend to vigorously defend against the allegations. Given the preliminary stage and the inherent uncertainty of the potential outcome of such proceedings, we cannot estimate the reasonably possible range of loss at this time. Based on the available information, we believe that the low end of the reasonably possible range of loss is zero and, accordingly, no loss accrual has been provided in our accompanying financial statements.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with “Selected Financial Data” and our consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K. In addition to historical information, this discussion and analysis contains forward-looking statements relating to future events and the future performance of MarketAxess that are based on our current expectations, assumptions, estimates and projections about us and our industry. These forward-looking statements involve risks and uncertainties. Our actual results and timing of various events could differ materially from those anticipated in such forward-looking statements as a result of a variety of factors, as more fully described in this section, in “Item 1A. — Risk Factors” and elsewhere in this Annual Report on Form 10-K. We undertake no obligation to update publicly any forward-looking statements for any reason, even if new information becomes available or other events occur in the future.

Executive Overview

MarketAxess operates a leading electronic trading platform that allows investment industry professionals to efficiently trade corporate bonds and other types of fixed-income instruments. Our approximately 1,000 active institutional investor clients (firms that executed at least one trade in U.S. or European fixed-income securities through our electronic trading platform during 2012) include investment advisers, mutual funds, insurance companies, public and private pension funds, bank portfolios, broker-dealers and hedge funds. Our 87 broker-dealer market-maker clients provide liquidity on the platform and include most of the leading broker-dealers in global fixed-income trading. The Company also executes certain bond transactions between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller in matching back-to-back trades, which then settle through a third-party clearing organization. Through our Corporate BondTicker™ service, we provide fixed-income market data, analytics and compliance tools that help our clients make trading decisions. In addition, we provide FIX (Financial Information eXchange) message management tools, connectivity solutions and ancillary technology services that facilitate the electronic communication of order information between trading counterparties. Our revenues are primarily generated from the trading of U.S. high-grade corporate bonds.

Our multi-dealer trading platform allows our institutional investor clients to simultaneously request competing, executable bids or offers from our broker-dealer clients and execute trades with the broker-dealer of their choice from among those that choose to respond. We offer our broker-dealer clients a solution that enables them to efficiently reach our institutional investor clients for the distribution and trading of bonds. In addition to U.S. high-grade corporate bonds, European high-grade corporate bonds and emerging markets bonds, including both investment-grade and non-investment grade debt, we also offer our clients the ability to trade crossover and high-yield bonds, agency bonds, asset-backed and preferred securities and credit default swaps.

The majority of our revenues are derived from monthly distribution fees and commissions for trades executed on our platform that are billed to our broker-dealer clients on a monthly basis. We also derive revenues from technology products and services, information and user access fees, investment income and other income. Our expenses consist of employee compensation and benefits, depreciation and amortization, technology and communication costs, professional and consulting fees, occupancy, marketing and advertising and other general and administrative expenses.

Our objective is to provide the leading global electronic trading platform for fixed-income securities, connecting broker-dealers and institutional investors more easily and efficiently, while offering a broad array of information, trading and technology services to market participants across the trading cycle. The key elements of our strategy are:

Critical Factors Affecting Our Industry and Our Company

Economic, Political and Market Factors

The global fixed-income securities industry is risky and volatile and is directly affected by a number of economic, political and market factors that may result in declining trading volume. These factors could have a material adverse effect on our business, financial condition and results of operations. These factors include, among others, credit market conditions, the current interest rate environment, including the volatility of interest rates and investors’ forecasts of future interest rates, economic and political conditions in the United States, Europe and elsewhere, and consolidation or contraction of broker-dealers.

Competitive Landscape

The global fixed-income securities industry generally, and the electronic financial services markets in which we engage, in particular, are highly competitive, and we expect competition to intensify in the future. Sources of competition for us will continue to include, among others, bond trading conducted directly between broker-dealers and their institutional investor clients over the telephone or electronically and other multi-dealer trading companies. Competitors, including companies in which some of our broker-dealer clients have invested, have developed electronic trading platforms or have announced their intention to explore the development of electronic platforms that may compete with us.

In general, we compete on the basis of a number of key factors, including, among others, the liquidity provided on our platform, the magnitude and frequency of price improvement enabled by our platform and the quality and speed of execution. We believe that our ability to grow volumes and revenues will largely depend on our performance with respect to these factors.

Our competitive position is also enhanced by the familiarity and integration of our broker-dealer and institutional investor clients with our electronic trading platform and other systems. We have focused on the unique aspects of the credit markets we serve in the development of our platform, working closely with our clients to provide a system that is suited to their needs.

Regulatory Environment

Our industry has been and is subject to continuous regulatory changes and may become subject to new regulations or changes in the interpretation or enforcement of existing regulations, which could require us to incur significant costs.

Our U.S. subsidiary, MarketAxess Corporation, is a registered broker-dealer with the SEC and is a member of FINRA. Our U.K. subsidiary, MarketAxess Europe Limited, is registered as a multilateral trading facility dealer with the FSA in the U.K. MarketAxess Canada Limited, a Canadian subsidiary, is registered as an Alternative Trading System dealer under the Securities Act of Ontario and is a member of the Investment Industry Regulatory Organization of Canada. Relevant regulations prohibit repayment of borrowings from these subsidiaries or their affiliates, paying cash dividends, making loans to us or our affiliates or otherwise entering into transactions that result in a significant reduction in regulatory net capital or financial resources, without prior notification to or approval from such regulated entity’s principal regulator.

Table of Contents

In July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) was signed into law. U.S. financial regulators are in the midst of an intense period of rulemaking that is required to implement the provisions of the Dodd-Frank Act, and market participants will need to make strategic decisions in an environment of regulatory uncertainty. Among the most significant aspects of the derivatives section of the Dodd-Frank Act are mandatory clearing of certain derivatives transactions (“swaps”) through regulated central clearing organizations and mandatory trading of those swaps through either regulated exchanges or swap execution facilities, in each case, subject to certain key exceptions. As with other parts of the Dodd-Frank Act, many of the details of the new regulatory regime relating to swaps are left to the regulators to determine through rulemaking. While the U.S. Commodity Futures Trading Commission and the SEC have adopted a number of rules that implement certain aspects of the new regulatory regime regarding the swaps market place, no assurance can be given regarding when, or whether, the remaining rules, including, among others, the rules regarding swap execution facilities and security-based swap execution facilities, will be finalized or implemented. Subject to such rulemaking, we currently expect to establish and operate a swap execution facility and/or a security-based swap execution facility.

The proposed Volcker Rule section of the Dodd-Frank Act bans proprietary trading by banks and their affiliates. The Volcker Rule could adversely affect our bank-affiliated broker-dealer clients’ ability to make markets in a variety of fixed-income securities, thereby negatively impacting the level of liquidity and pricing available on our trading platform. We cannot predict the extent to which any future regulatory changes may adversely affect our business and operations.

Similar to the U.S., regulatory bodies in Europe and elsewhere are developing new rules for derivatives trading. For example, the European Parliament and the EU Council of Ministers endorsed an agreement that will, among other things, require central clearing of standardized OTC derivatives and the reporting of all derivatives (OTC or otherwise) to trade repositories. However, it is not yet clear whether there will be any requirement in the EU to trade standardized CDS contracts on regulated exchanges or trading platforms.

Rapid Technological Changes

We must continue to enhance and improve our electronic trading platform. The electronic financial services industry is characterized by increasingly complex systems and infrastructures and new business models. Our future success will depend on our ability to enhance our existing products and services, develop and/or license new products and technologies that address the increasingly sophisticated and varied needs of our broker-dealer and institutional investor clients and prospective clients and respond to technological advances and emerging industry standards and practices on a cost-effective and timely basis. We have received 11 patents covering our most significant trading protocols and other aspects of our trading system technology and additional patents are pending.

Trends in Our Business

The majority of our revenues are derived from monthly distribution fees and commissions for transactions executed on our platform between our institutional investor and broker-dealer clients. We believe that there are five key variables that impact the notional value of such transactions on our platform and the amount of commissions and distribution fees earned by us:

We believe that overall corporate bond market trading volume is affected by various factors including the absolute levels of interest rates, the direction of interest rate movements, the level of new issues of corporate bonds and the volatility of corporate bond spreads versus U.S. Treasury securities. Because a significant percentage of our revenue is tied directly to the volume of securities traded on our platform, it is likely that a general decline in trading volumes, regardless of the cause of such decline, would reduce our revenues and have a significant negative impact on profitability.

-46-

Table of Contents

Commission Revenue

Commissions are generally calculated as a percentage of the notional dollar volume of bonds traded on our platform and vary based on the type, size, yield and maturity of the bond traded. The commission rates are based on a number of factors, including fees charged by inter-dealer brokers in the respective markets, average bid-offer spreads in the products we offer and transaction costs through alternative channels including the telephone. Under our transaction fee plans, bonds that are more actively traded or that have shorter maturities are generally charged lower commissions, while bonds that are less actively traded or that have longer maturities generally command higher commissions.

U.S. High-Grade Corporate Bond Commissions. Our U.S. high-grade corporate bond fee plans for fully electronic trades generally incorporate monthly distribution fees and variable transaction fees billed to our broker-dealer clients on a monthly basis. Certain dealers participate in fee programs that do not contain monthly distribution fees and instead incorporate additional per transaction execution fees and minimum monthly fee commitments. Under the fee plans, we electronically add the transaction fee to the spread quoted by the broker-dealer client. The U.S. high-grade transaction fee is generally designated in basis points in yield and, as a result, is subject to fluctuation depending on the duration of the bond traded. The average U.S. high-grade fees per million may vary in the future due to changes in yield and years-to-maturity of bonds traded on our platform.

Eurobond Commissions. Similar to the U.S. high-grade plans, our European fee plan incorporates monthly distribution fees as well as variable transaction fees. In June 2010, we launched a click-to-trade protocol in the European market. Click-to-trade is offered alongside our request-for-quote product and consists of streamed indicative pricing in credit and rates products. Clients have the ability to request a trade at the displayed price with the indicated dealer. In connection with the launch, the Eurobond fee plan was revised and a standard commission rate was established across most types of bonds. Prior to this change, the variable transaction fee was dependent on the type of bond traded and the maturity of the issue.

Other Commissions. Commissions for other bond, asset-backed and preferred securities trades generally vary based on the type and the maturity of the instrument traded. We generally operate using standard fee schedules that may include both transaction fees and monthly distribution fees that are charged to the participating dealers.

For trades that we execute between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller, we earn our commission through the difference in price between the two back-to-back trades.

We anticipate that average fees per million may change in the future. Consequently, past trends in commissions are not necessarily indicative of future commissions.

Other Revenue

In addition to the commissions discussed above, we earn revenue from technology products and services, information services fees paid by institutional investor and broker-dealer clients, income on investments and other income.

Technology Products and Services. Technology products and services includes software licenses, maintenance and support services and professional consulting services.

Information and User Access Fees. We charge information services fees for Corporate BondTicker^TM to our broker-dealer clients, institutional investor clients and data-only subscribers. The information services fee is a flat monthly fee, based on the level of service. We also generate information services fees from the sale of bulk data to certain institutional investor clients and data-only subscribers. Institutional investor clients trading U.S. high-grade corporate bonds are charged a monthly user access fee for the use of our platform. The fee, billed quarterly, is charged to the client based on the number of the client’s users. To encourage institutional investor clients to execute trades on our platform, we reduce these information and user access fees for such clients once minimum quarterly trading volumes are attained.

Investment Income. Investment income consists of income earned on our investments.

Other. Other revenues include fees from telecommunications line charges to broker-dealer clients, initial set-up fees and other miscellaneous revenues.

Expenses

In the normal course of business, we incur the following expenses:

Employee Compensation and Benefits. Employee compensation and benefits is our most significant expense and includes employee salaries, stock-based compensation costs, other incentive compensation, employee benefits and payroll taxes.

Depreciation and Amortization. We depreciate our computer hardware and related software, office hardware and furniture and fixtures and amortize our capitalized software development costs on a straight-line basis over three to seven years. We amortize leasehold improvements on a straight-line basis over the lesser of the life of the improvement or the remaining term of the lease. Intangible assets with definite lives, including purchased technologies, customer relationships and other intangible assets, are amortized over their estimated useful lives, ranging from five to ten years. Intangible assets are assessed for impairment when events or circumstances indicate a possible impairment.

Technology and Communications. Technology and communications expense consists primarily of costs relating to maintenance on software and hardware, our internal network connections, data center hosting costs and data feeds provided by outside vendors or service providers. The majority of our broker-dealer clients have dedicated high-speed communication lines to our network in order to provide fast data transfer. We charge our broker-dealer clients a monthly fee for these connections, which is recovered against the relevant expenses we incur.

Professional and Consulting Fees. Professional and consulting fees consist primarily of accounting fees, legal fees and fees paid to information technology and non-information technology consultants for services provided for the maintenance of our trading platform and information services products.

Occupancy. Occupancy costs consist primarily of office and equipment rent, utilities and commercial rent tax.

Marketing and Advertising. Marketing and advertising expense consists primarily of print and other advertising expenses we incur to promote our products and services. This expense also includes costs associated with attending or exhibiting at industry-sponsored seminars, conferences and conventions, and travel and entertainment expenses incurred by our sales force to promote our trading platform and information services.

General and Administrative. General and administrative expense consists primarily of general travel and entertainment, board of directors’ expenses, charitable contributions, provision for doubtful accounts, and various state franchise and U.K. value-added taxes.

Expenses may grow in the future, notably in employee compensation and benefits, primarily due to investment in new products and geographic expansion. However, we believe that operating leverage can be achieved by increasing volumes in existing products and adding new products without substantial additions to our infrastructure.

Critical Accounting Estimates

This Management’s Discussion and Analysis of Financial Condition and Results of Operations discusses our Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States, also referred to as U.S. GAAP. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of income and expenses during the reporting periods. We base our estimates and judgments on historical experience and on various other factors that we believe are reasonable under the circumstances. Actual results may differ from these estimates under varying assumptions or conditions. Note 2 of the Notes to our Consolidated Financial Statements includes a summary of the significant accounting policies and methods used in the preparation of our Consolidated Financial Statements.

Use of Estimates

On an ongoing basis, management evaluates its estimates and judgments, particularly as they relate to accounting policies that management believes are critical. That is, these accounting policies are most important to the portrayal of our financial condition and results of operations and they require management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

Allowance for Doubtful Accounts

All accounts receivable have contractual maturities of less than one year and are derived from trading-related fees and commissions and revenues from products and services. We continually monitor collections and payments from our customers and maintain an allowance for doubtful accounts. The allowance for doubtful accounts is based upon the historical collection experience and specific collection issues that have been identified.

Software Development Costs

We capitalize certain costs associated with the development of internal use software at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed. We capitalize employee compensation and related benefits and third party consulting costs incurred during the preliminary software project stage. Once the product is ready for its intended use, such costs are amortized on a straight-line basis over three years. We review the amounts capitalized for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable.

Revenue Recognition

The majority of our revenues are derived from monthly distribution fees and commissions for trades executed on our platform that are billed to our broker-dealer clients on a monthly basis. We also derive revenues from technology products and services, information and user access fees, investment income and other income.

Commission revenue. Commissions are generally calculated as a percentage of the notional dollar volume of bonds traded on the platform and vary based on the type and maturity of the bond traded. Under our transaction fee plans, bonds that are more actively traded or that have shorter maturities are generally charged lower commissions, while bonds that are less actively traded or that have longer maturities generally command higher commissions. For trades that we execute between and among institutional investor and broker-dealer clients on a riskless principal basis by serving as counterparty to both the buyer and the seller, we earn the commission through the difference in price between the two back-to-back trades. Fee programs for certain products include distribution fees which are recognized monthly.

Technology products and services. We generate revenues from technology software licenses, maintenance and support services (referred to as post-contract technical support or “PCS”) and professional consulting services. Revenue is generally recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collection is considered probable. We generally sell software licenses and PCS together as part of multiple-element arrangements. We also enter into contracts for technology integration consulting services unrelated to any software product.

For arrangements that include multiple elements, generally software licenses and PCS, we allocate and defer revenue for the undelivered items based on vendor specific objective evidence (“VSOE”) of the fair value of the undelivered elements and recognize the difference between the total arrangement fee and the amount deferred for the undelivered items as license revenue. The VSOE of each element is based on historical evidence of stand-alone sales of these elements to third parties or the stated renewal rate for the undelivered elements. When VSOE does not exist for undelivered items, the entire arrangement fee is recognized ratably over the performance period. For PCS, the term is typically one year and revenue is recognized over the duration of the arrangement on a straight-line basis.

Professional consulting services are generally separately priced and are typically not essential to the functionality of the software products. Revenues from these services are recognized separately from the license fee. Generally, revenue from time-and-materials consulting contracts is recognized as services are performed.

Revenues from contracts for technology integration consulting services are recognized on the percentage-of-completion method. Percentage-of-completion accounting involves calculating the percentage of services provided during the reporting period compared to the total estimated services to be provided over the duration of the contract. If estimates indicate that a contract loss will occur, a loss provision is recorded in the period in which the loss first becomes probable and reasonably estimable. Contract losses are determined to be the amount by which the estimated direct and indirect costs of the contract exceed the estimated total revenues that will be generated by the contract. Revenues recognized in excess of billings are recorded as unbilled services within other assets. Billings in excess of revenues recognized are recorded as deferred revenues until revenue recognition criteria are met.

Initial set-up fees. We enter into agreements with our broker-dealer clients pursuant to which we provide access to our platform through a non-exclusive and non-transferable license. Broker-dealer clients may pay an initial set-up fee, which is typically due and payable upon execution of the broker-dealer agreement. The initial set-up fee, if any, varies by agreement. Revenue is recognized over the initial term of the agreement, which is generally two years.

Stock-Based Compensation

We measure and recognize compensation expense for all share-based payment awards based on their estimated fair values measured as of the grant date. These costs are recognized as an expense in the Consolidated Statements of Operations over the requisite service period, which is typically the vesting period, with an offsetting increase to additional paid-in capital.

Income Taxes

Income taxes are accounted for using the asset and liability method. Deferred income taxes reflect the net tax effects of temporary differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when such differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized against deferred tax assets if it is more likely than not that such assets will not be realized in future years. We recognize interest and penalties related to unrecognized tax benefits in general and administrative expenses in the Consolidated Statements of Operations.

Business Combinations, Goodwill and Intangibles Assets

Business combinations are accounted for under the purchase method. The total cost of an acquisition is allocated to the underlying net assets based on their respective estimated fair values. The excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Determining the fair value of certain assets acquired and liabilities assumed is judgmental in nature and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash flows, discount rates, growth rates and asset lives.

We perform an impairment review of goodwill on an annual basis and more frequently if circumstances change. Intangible assets with definite lives, including purchased technologies, customer relationships and other intangible assets, are amortized on a straight-line basis over their estimated useful lives, ranging from five to ten years. Intangible assets are assessed for impairment when events or circumstances indicate a possible impairment.

Segment Results

As an electronic, multi-dealer platform for trading fixed-income securities, our operations constitute a single business segment. Because of the highly integrated nature of the financial markets in which we compete and the integration of our worldwide business activities, we believe that results by geographic region, products or types of clients are not necessarily meaningful in understanding our business.

Due in part to the continuing sovereign debt concerns and the competitive environment in Europe, trading volume in our Eurobond product significantly decreased over the past several years. Monthly distribution fees paid by most of our European broker-dealer market makers were reduced effective March 1, 2012, but the dealer variable fee schedule remained unchanged. Several additional European broker-dealer market-makers remain on the original fee plan and may move to the new fee plan in the future.
