Tradeweb Markets Inc. 10-K

ITEM 1. BUSINESS. Overview We are a leader in building and operating electronic marketplaces for our global network of clients across the financial ecosystem. Our network is comprised of clients across the institutional, wholesale and retail client sectors, including many of the largest global asset managers, hedge funds, insurance companies, central banks, banks and dealers, proprietary trading firms and retail brokerage and financial advisory firms, as well as regional dealers. Our marketplaces facilitate trading across a range of asset classes, including rates, credit, equities and money markets. We are a global company serving clients in over 70 countries with offices in North America, Europe, Asia, Australia and the Middle East. We believe our proprietary technology and culture of collaborative innovation allow us to adapt our offerings to enter new markets, create new platforms and solutions and adjust to regulations quickly and efficiently. We support our clients by providing solutions across the trade lifecycle, including pre-trade, execution, post-trade and data. There are multiple key dimensions to the electronic marketplaces that we build and operate to provide deep pools of liquidity. Foundationally, these begin with our clients and then expand through and across multiple client sectors, geographic regions, asset classes, product groups, trading protocols and trade lifecycle solutions. Our markets are large and growing. Electronic trading continues to increase in the markets in which we operate as a result of market demand for greater transparency, higher execution quality, operational efficiency and lower costs, as well as regulatory changes. We believe our deep client relationships, asset class breadth, geographic reach, regulatory knowledge and scalable technology position us to continue to be at the forefront of the evolution of electronic trading. Our platforms provide transparent, efficient, cost-effective and compliant trading solutions across multiple products, regions and regulatory regimes. As market participants seek to trade across multiple asset classes, reduce their costs of trading and increase the effectiveness of their trading, including through the use of data and analytics, we believe the demand for our platforms and electronic trading solutions will continue to grow. We have a powerful network of more than 2,500 clients across the institutional, wholesale and retail client sectors. Our clients include leading global asset managers, hedge funds, insurance companies, central banks, banks and dealers, proprietary trading firms and retail brokerage and financial advisory firms, as well as regional dealers. As our network continues to grow across client sectors, we will generate additional transactions and data on our platforms, driving a virtuous cycle of greater liquidity and value for our clients. Our technology supports multiple asset classes, trading protocols and geographies, and as a result, we are able to provide a broad spectrum of solutions and cost savings to our clients. We have built, and continue to invest in, a scalable, flexible and resilient proprietary technology architecture that enables us to remain agile and evolve with market structure. This allows us to partner closely with our clients to develop customized solutions for their trading and workflow needs. Our technology is deeply integrated with our clients’ risk and order management systems, clearinghouses, trade repositories, middleware providers and other important links in the trading value chain. These qualities allow us to be quick to market with new offerings, to constantly enhance our existing platforms and solutions and to collect a robust set of data and analytics to support our marketplaces. 9 Table of Contents We are focused on balancing revenue growth and margin expansion to create long-term value and we have a track record of growth and financial performance. By expanding the scope of our platforms and solutions, building scale and integration across marketplaces and benefiting from broader network effects, we have been able to grow both our transaction volume and subscription-based revenues. Our Evolution We were founded in 1996 and set out to solve for inefficiencies in the institutional U.S. Treasury trading workflows, including limited price transparency, weak connectivity among market participants and error-prone manual processes. Our first electronic marketplace went live in 1998, and for more than 25 years we have leveraged our technology and expertise to expand into additional rates products and other asset classes, including credit, equities and money markets. Market demand for better trading workflows globally also was increasing and we initiated a strategy of rolling out our existing products to new geographies and adding local products. We expanded to Europe in 2000, initially offering U.S. fixed income products and soon thereafter added a marketplace for European government bonds. We expanded to Asia in 2004, where our first local product was Japanese government bonds. We have since continued to expand our product and client base in Europe, Asia and most recently in Australia, Africa, South America and the Middle East. We identified an opportunity to complement our offerings to the wholesale and retail client sectors based on our existing relationships with dealers and our strong market position. We developed our wholesale platform through the acquisitions of Hilliard Farber & Co. in 2008 and Rafferty Capital Markets in 2011, and developed technology to facilitate the migration of inefficient wholesale voice markets to more efficient and transparent electronic markets. We entered the retail market through our acquisition of LeverTrade in 2006, scaled our market position through our acquisition of BondDesk in 2013, and have continued to leverage our market and technology expertise to enhance our platform serving that client sector. In June 2021, we acquired Nasdaq’s U.S. fixed income electronic trading platform. The addition of this fully-electronic CLOB (central limit order book) offers a flexible, efficient approach to trading in the wholesale U.S. Treasury market. In August 2023, we acquired Tradeweb Australia Pty Ltd (formerly Yieldbroker Pty Limited) (“Yieldbroker”), a leading Australian trading platform for Australian and New Zealand government bonds and interest rate derivatives covering the institutional and wholesale client sectors. This acquisition combines Australia and New Zealand’s highly attractive, fast-growing markets with Tradeweb’s international reach and scale. In January 2024, we acquired R8FIN Holdings LP (together with its subsidiaries, “r8fin”), a technology provider that specializes in algorithmic-based execution for U.S. Treasuries and interest rate futures that complement our other offerings, creating a valuable and broad-based approach to trading. Throughout our evolution we have developed many new innovations that have provided greater pre-trade price transparency, better execution quality and seamless post-trade solutions. Such innovations include the introduction of pre-trade composite pricing for multi-dealer-to-customer (“D2C”) trading, the Request-for-Quote (“RFQ”) trading protocol across all of our asset classes, the blast all-to-all (“A2A”) trading protocol across our global credit marketplaces and portfolio trading. We have also integrated our trading platforms with our proprietary post-trade systems as well as many of our clients’ order management and risk systems for efficient post-trade processing. In addition, because large components of the market remain relationship-driven, we continue to focus on introducing technology solutions to solve inefficiencies in voice markets, such as electronic voice processing, which allows our clients to use Tradeweb technology to process voice trades. We expect to continue to leverage our success to expand into new products, asset classes and geographies, while growing our powerful network of clients. While our cornerstone products continue to be some of the first products we launched, including U.S. Treasuries, European government bonds and To-Be-Announced mortgage-backed securities (“TBA MBS”), we have continued to solve trading inefficiencies by adding new products across our rates, credit, equities and money markets asset classes. As a result of expanding our offerings, we have increased our opportunities in related addressable markets, where estimated average daily trading volumes have grown from approximately $0.6 trillion in 1998 to $8.8 trillion through December 31, 2023, according to industry sources and management estimates. 10 Table of Contents Our Competitive Strengths Our Network of Clients, Products, Geographies and Protocols Our clients continue to use our trading venues because of our large network and deep pools of liquidity, which result in better and more efficient trade execution. We expand our relationships through our integrated technology and new offerings made available to our growing network of clients. As an electronic trading marketplace for key asset classes and products, we benefit from a virtuous cycle of liquidity — trading volumes growing together and re-enforcing each other. We expect our existing clients to trade more volume on our trading venues and to attract new users to our already powerful network, as liquidity on our marketplaces continues to grow and we offer more products and value-added solutions. The breadth of our network, products, global presence and embedded scalable technology offers us unique insights and an established platform to swiftly enter additional markets and offer new value-added solutions. This is supported by more than 25 years of successful innovation and long trusted relationships with our clients. We are a leader in making trading and the associated workflow more efficient for market participants. Based on industry sources and management estimates, we believe that we are a market leader in electronic trading for the following products: U.S. Treasuries, U.S. High-Grade credit, TBA MBS, European government bonds, global interest rate swaps, ETP-traded Yen-denominated interest rate swaps and European exchange traded funds (“ETFs”). We cover all major client sectors participating in electronic trading, including the institutional, wholesale and retail client sectors. In addition, we provide a full spectrum of trading protocols including voice, sweeps (session-based trading), RFQ, CLOB, A2A and portfolio trading, among others. We believe the breadth of our offerings, experience and client relationships provides us unique market feedback and enables us to enter new markets with higher probabilities of success and greater speed. Many of our markets are interwoven and we provide participants trading capabilities across multiple products through a single relationship. We cover our global clients through offices in North America, Europe, Asia, Australia and the Middle East and a global trading network that is distributed throughout the world. Culture of Collaborative Innovation We have developed trusted client relationships through a culture of collaborative innovation where we work alongside our clients to solve their evolving workflow needs. We have a long track record of working with clients to solve both industry-level challenges and client-specific issues. We have had a philosophy of collaboration since our founding, when we worked with certain clients to improve U.S. Treasury trading for the institutional client sector. More recently, we introduced Tradeweb’s Rematch, an industry-exclusive solution, offering institutional investors trading within AllTrade previously unavailable access to hundreds of millions of dollars in unmatched risk from dealers’ sessions, opening the door to a significantly larger pool of liquidity. We were also the first trading platform to offer portfolio trading for corporate bonds, creating a new and efficient way for participants to move risk. We helped make trading in credit markets more efficient by partnering with major dealers to improve liquidity and reduce the cost of net spotting the U.S. Treasury in connection with a corporate bond trade. This net spotting functionality allows our credit clients to spot multiple bonds at the same time using our multi-dealer net spotting tool to net their interest rate risk simultaneously using one spot price. We have also worked side-by-side with clients and federal agencies to customize solutions for their particular needs in the TBA MBS market. For example, in direct collaboration with our leading TBA MBS clients we developed our Round Robin functionality to help resolve the issue of systemic fails on TBA MBS trades and reduce the operational risk and costs associated with delivery failures that often plague the TBA MBS market. In conjunction with Freddie Mac, we developed a direct-to-Freddie Mac exchange path for institutional clients related to the single security initiative, paving the way for a combined Freddie Mac and Fannie Mae TBA market of Uniform Mortgage-Backed Securities. Through collaborative endeavors like these, we have become deeply integrated into our clients’ workflow and become a partner of choice for new innovations. 11 Table of Contents Scalable and Flexible Technology We consistently use our proprietary technology to find new ways for our clients to trade more effectively and efficiently. Our core software solutions span multiple components of the trading lifecycle and include pre-trade data and analytics, trade execution and post-trade data, analytics and reporting, integration, connectivity and straight-through processing. Our systems are built to be scalable, flexible and resilient. Our internet-based, thin client technology is readily accessible and enables us to quickly access the market with easily distributed new solutions. For example, we were the first to offer web-based electronic multi-dealer trading to the institutional U.S. Treasury market and have subsequently automated the market structure of additional markets globally. We have also created new trading protocols and developed additional solutions for our clients that are translated and built by our highly experienced technology and business personnel working together to solve a client workflow problem. Our 2024 acquisition of the r8fin technology will help us reach a new and differentiated level of intelligent execution through a powerful combination of algorithmic technology and cross-market connectivity. We believe pairing r8fin’s sophisticated technology with our global network will open up a range of new possibilities for clients engaged in relative value or macro trades spanning multiple asset classes. Going forward, we expect our technology platform, and ongoing investments in technology and new product offerings, to help us stay at the forefront of the evolution of electronic trading. Our Global Regulatory Footprint and Domain Expertise We are regulated (as necessitated by jurisdiction and applicable law) or have necessary legal clearance to offer our platforms and solutions in major markets globally, and our experience provides us credibility when we enter new markets and facilitates our ability to comply with additional regulatory regimes. With extensive experience in addressing existing and pending regulatory changes in our industry, we offer clients a central source of expertise and thought leadership in our markets and assist them through the myriad of regulatory requirements. We then provide our clients with trading platforms that meet regulatory requirements and enable connectivity to pre- and post-trade systems necessary to comply with their regulatory obligations. Platforms and Solutions Empowered by Data and Analytics Our data and analytics enhance the value proposition of our trading venues and improve the trading experience of our clients. We support our clients’ core trading functions by offering trusted pre- and post-trade services, value-added analytics and predictive insights informed by our deep understanding of how market participants interact. Our data and analytics help clients make better trading decisions, benefitting our current clients and attracting new market participants to our network. For example, data powers our Automated Intelligent Execution (“AiEX”) functionality which allows traders to automatically execute trades according to pre-programmed rules and automatically sends completed or rejected order details to internal order management systems. By allowing traders to automate and execute their smaller, low touch trades more efficiently, AiEX helps traders focus their attention on larger, more nuanced trades. During the year ended December 31, 2023, the percentage of trades executed by our institutional clients using our AiEX functionality was over 35% of total institutional trades, up from 6% in 2015, and we are seeing demand for AiEX continue to grow across some of our key products, including U.S. Treasuries, European government bonds, global swaps, U.S. corporate bonds and global ETFs. Our over 25 year operating history has allowed us to build comprehensive and unique datasets across our markets and, as we add new products to our platforms, we will continue to create new datasets that may be monetized in the future. Our marketplaces generate valuable data, processing on average over 130,000 trades and significantly more pre-trade price updates daily, that we collect centrally and use as inputs to our pre-trade indicative pricing and analytics. We maintain a full history of inquiries and transactions, which means, for example, we have over 25 years of U.S. Treasury data. With markets becoming more electronic, clients increasingly turn to our composite data for its transparency and to help improve execution, further increasing the value proposition of our data. For example, in October 2023, we signed an amended and restated two-year market data license agreement with an affiliate of LSEG (formerly referred to as Refinitiv), pursuant to which LSEG will continue to distribute certain of our data directly to LSEG customers through its flagship financial platforms, LSEG Workspace, Datascope, LSEG Pricing Service and Tick History. The 2023 agreement, which was effective on November 1, 2023, replaced an existing agreement that was initiated in 2010 and most recently renewed in 2018, and provides us with increased revenue and flexibility in growing our market data offering. We will seek to further monetize our data over time both through potential expansion of our existing market data license agreement with LSEG and through distributing additional datasets, derived data and analytics offerings through our own network or through other third-party networks. For example, in October 2023, we also announced a strategic partnership with FTSE Russell which will seek to develop the next generation of fixed income pricing and index trading products. Fixed income closing prices will be administered as benchmarks by FTSE Russell and be derived from trading activity on our platform. The partnership aims to extend pricing coverage to most constituents featured in the FTSE Fixed Income Index universes and explore incorporating new Tradeweb pricing sets into FTSE Fixed Income Indices. 12 Table of Contents We are also continuously developing new offerings and solutions to meet the changing needs of our clients. For example, in 2023, we launched a new market data service to calculate real-time indicative net asset values (“iNAVs”) for ETFs. Our breadth of product coverage, depth of price contributions and timeliness of quotes help position Tradeweb iNAVs to become the market’s preferred solution for intraday ETF evaluation, which could ultimately boost trading confidence in the ETF market. Our offerings also include Automated Intelligent Pricing (“Ai-Price”), an innovative bond pricing engine that applies data science to help make markets more efficient and delivers reliable reference pricing for U.S. corporate and municipal bonds, regardless of how frequently a bond trades. Clients leverage the service to power their AiEX auto-trading, portfolio trading, and Transaction Cost Analysis (“TCA”). Experienced Management Team Our focus and decades of experience have enabled us to accumulate the knowledge and capabilities needed to serve complex, dynamic and highly regulated markets, and oversee our expansion into new markets and geographies while managing ongoing strategic initiatives including our significant technology investments. Our management team is composed of executives with an average of over 25 years of relevant industry experience including an average of over 10 years working together at Tradeweb under different ownership structures and through multiple market cycles, with a combination of veteran Tradeweb employees such as Mr. Billy Hult, who has been at the Company for over 20 years and took over as our Chief Executive Officer effective January 1, 2023 and new executives, including Mr. Thomas Pluta, who became our President effective as of January 1, 2023. Management has fostered a culture of collaborative innovation with our clients, which combined with management’s focus and experience, has been an important contributor to our success. We have been thought leaders and contributors to the public dialogue on key issues and regulations affecting our markets and industry, including congressional testimony, public roundtables, regulatory committees and industry panels. Our Growth Strategies Throughout our history, we have operated with agility to address the evolving needs of our clients. We have been guided by our core principles, which are to build better marketplaces, to forge new relationships and to create trading solutions that position us as a strategic partner to the clients that we serve. We seek to advance our leadership position by focusing our efforts on the following growth strategies: Continue to Grow Our Existing Markets We believe there are significant opportunities to generate additional revenue from secular and cyclical tailwinds in our existing markets: Growth in Our Underlying Asset Classes The underlying volumes in our asset classes continue to increase due to increased government and corporate issuance. In addition, the government bond market is foundational to and correlative to virtually every asset class in the cash and derivatives fixed income markets. Select products that we believe have a high growth potential due to current market trends include global government bonds, global interest rate swaps, ETFs and credit cash products. Growth in Our Market Share Our clients represent most of the largest institutional, wholesale and retail market participants. The global rates, credit, equities and money markets asset classes continue to evolve electronically, and we seek to increase our market share by continuing to innovate to electronify workflows. We intend to continue to increase our market share by growing our client base and increasing the percentage of our clients’ overall trading volume transacted in those asset classes on our platforms, including by leveraging our voice solutions to win more electronic trading business from electronic voice processing clients in our rates and credit asset classes. In particular, across many of our products, we are implementing an integrated approach to grow our market share — serving all three of our client sectors across all trade sizes, from odd-lot to block trades, through a variety of protocols. Many of our asset manager, hedge fund, insurance, central bank/sovereign entity and regional dealer clients actively trade multiple products on our platforms. In addition, our global dealer clients trade in most asset classes across all three client sectors. We also see a growing appetite for multi-asset trading to reduce cost and duration risk. 13 Table of Contents Electronification of Our Markets Market demands and regulation are changing the paradigm of trading and driving the migration to electronic markets. Our clients desire transparency, best execution and choice of trading protocols amidst dynamic and evolving markets. Furthermore, innovations in capital markets have enabled increased automation and process efficiency across our markets. The electronification of our marketplaces varies by product. We typically see meaningful electronification of new products within three to five years of their launch, with certain products experiencing significant revenue growth following that period of time, including as a result of market and regulatory developments. For example, our U.S.- and euro-denominated derivative products experienced increased rates of electronification and related revenue growth following the implementation of mandates under the Dodd-Frank Act in 2013 and MiFID II in 2018 and we saw strong electronification increases in U.S. corporate bonds, repurchase agreements and swaps during the COVID-19 pandemic. We are well positioned to continue to innovate and provide better electronic markets and solutions that satisfy the needs of our clients and that meet changing market demands and evolving regulatory standards. We believe that global government bonds, global interest rate swaps, global ETFs, in particular, institutional block ETFs, cash credit products, including corporate high grade and high yield bonds and emerging markets are key drivers of our potential growth. Our penetration of these markets, and their level of electronification, are at various stages. We are focused on growing our market share for these products by continuing to invest in new technology solutions that will attract new market participants to our platforms and increase the use of our platforms by existing clients. Expand Our Product Set and Reach We have grown our business by prudently expanding our offerings to add new products and asset classes, and we expect to continue to invest to add new products and expand into new complementary markets as client demand and market trends evolve. In 2017, we expanded into China to offer our global clients access to the Chinese bond market through our initiative with BondConnect, where Northbound trading began in 2017, and in 2020 we launched CIBM Direct. During 2021, we completed our first Southbound BondConnect transactions for various bonds tradable in the Hong Kong bond market, offering onshore investors enhanced access to oversees liquidity, pre-trade transparency and innovative trading protocols. During 2023, we announced that institutional clients executing Japanese Yen swaps on our multilateral trading facilities and swap execution facilities would now be able to clear their transactions via the Japan Securities Clearing Corporation (“JSCC”), providing more connectivity, flexibility and choice in Yen swap trading. Also in 2023, we participated in the development of and added the ability for our clients to have direct trading access on our platform to Swap Connect, the world’s first derivatives market access scheme, where offshore investors can trade and central counterparty clear onshore Chinese Yuan Renminbi interest rate swaps without changing their existing trading and settlement practices. The interest rate swap trades are cleared through Hong Kong Exchange OTC Clear under Hong Kong’s internationally-familiar legal framework. We continue to focus on these initiatives and on expanding opportunities with clients in the Asia region more broadly. We have also expanded our product set to include wholesale electronic repurchase agreements, as well as U.S. and European bilateral repurchase agreements, European cash equities and U.S. options for our institutional client sector. We also intend to leverage innovation and technology capabilities to develop new solutions that help our clients trade more effectively and efficiently. For example, in 2023, we launched a new and innovative solution to help institutional investors trade EM bonds more efficiently, developed in collaboration with FXall, LSEG’s leading electronic platform for global currency products. This new FX swap workflow solution allows mutual clients of Tradeweb and FXall to buy or sell an EM bond via the request-for-quote or request-for-market protocols on Tradeweb and then seamlessly hedge the local currency risk by executing an FX swap trade via direct connection to FXall. In addition, our swap compression functionality allows clients to reduce their swap positions at the clearinghouse, resulting in significant cost savings. On our institutional U.S. credit platform, our portfolio trading solution allows clients to obtain competitive prices on a full basket of securities and trade on net present value from dealers. Our multi-asset package (MAP) trading allows clients to simultaneously execute interest rate swaps, inflations swaps and government bonds in a single electronic package enabling clients to achieve more competitive pricing, reduce manual booking errors and increase execution speed. Net spotting, which links our institutional U.S. credit and U.S. Treasury markets allows clients to reduce the operational stress and financial cost of executing offsetting Treasury hedges for corporate bonds that trade at a spread to the U.S. Treasury. Given the breadth of expertise of our sales people and management, we have the ability to focus on new client opportunities and on selling additional solutions to existing clients. 14 Table of Contents In addition, we believe our business model is well suited to serve market participants in other asset classes and geographies where our guiding principles can continue to transform markets and broaden our reach and we expect to grow our emerging markets footprint moving forward. Our international strategy involves offering our existing products in new geographies and then adding local products. In addition, we believe our trading models in one product or asset class are transferable to other products or asset classes, irrespective of geography. For example, we have leveraged our session-based trading technology in European corporate bonds for session-based trading in U.S. corporate bonds and Off-the-Run U.S. Treasuries and with our 2023 acquisition of Yieldbroker, we are well-positioned to seamlessly connect markets in Australia and New Zealand with our global network of clients and dealers. We have significant scale and breadth across our platforms, which position us well to take advantage of favorable market dynamics when introducing new products or solutions or entering into new markets. Enhance Underlying Data and Analytics Capabilities to Develop Innovative Solutions As the demand for data and analytics solutions grows across markets and geographies, we plan to continue to expand the scope of our underlying data, improve our tools and technology and enhance our analytics and trade decision support capabilities to provide innovative solutions that address this demand. As the needs of market participants evolve, we expect to continue to help them meet their challenges, which our continuous investments in data, technology and analytics enable us to do more quickly and efficiently. For example, we enhance our solutions by linking indicative pre-trade data to our clients’ specific trades to create predictive insights from client trading behavior. Our technology architecture reduces the time to market for new data solutions, which allows us to react quickly to client needs. Effective in November 2023, we entered an amended and restated, two-year agreement with an affiliate of LSEG (formerly referred to as Refinitiv), extending our long-term relationship where LSEG licenses certain data from us, which provides us with a predictable and growing revenue stream. We also have a roster of closing prices partnering with the FTSE Russell for UK Gilts and European government bonds and Intercontinental Exchange (“ICE”) for U.S. Treasuries in response to the growing demand for trusted reference price data that enables firms to manage investment portfolios, evaluate the fair value of securities, perform compliance monitoring and satisfy general accounting standards. In October 2023, we also announced a strategic partnership with FTSE Russell to develop the next generation of fixed income pricing and index trading products. The collaboration is focused on expanding benchmark pricing, broadening index inclusion and enhancing trading functionality across fixed income products. We will continue to selectively pursue new strategic partnerships to expand our data and analytics offering over time. Pursue Strategic Acquisitions and Alliances As part of our culture of collaborative innovation, throughout our history we have completed various acquisitions and initiated several formal strategic alliances. These alliances have taken several forms, including distribution partnerships, technological alliances and other financial arrangements. We intend to continue to selectively consider opportunities to grow through strategic alliances and acquisitions. For example, in June 2021, we acquired Nasdaq’s U.S. fixed income electronic trading platform and in November 2022, we entered into a multi-year partnership with BlackRock with the goal to integrate our credit trading solutions and data into BlackRock’s Aladdin order execution management system. In August 2023, we acquired Yieldbroker, a leading Australian trading platform for Australian and New Zealand government bonds and interest rate derivatives and in January 2024, we acquired r8fin, a technology provider that specializes in algorithmic-based execution for U.S. Treasuries and interest rate futures. These and other opportunities should enhance our existing capabilities, allow us to leverage the scale of other parties and accelerate our ability to enter new markets or provide new solutions. Our focus continues to be on opportunities that we believe can enhance or benefit from our technology platform and client network, provide significant market share and profitability and are consistent with our corporate culture. Our Client Sectors We have a powerful network of more than 2,500 clients across the institutional, wholesale and retail client sectors. Our clients include leading global asset managers, hedge funds, insurance companies, central banks, banks and dealers, proprietary trading firms and retail brokerage and financial advisory firms, as well as regional dealers. Since the founding of Tradeweb more than 25 years ago, we have developed trusted relationships with many of our clients and have invested to integrate with their capital markets technology infrastructures. This has facilitated the collaborative approach we employ to solve our clients’ evolving workflow needs. 15 Table of Contents We provide deep liquidity pools to the institutional, wholesale and retail client sectors through our Tradeweb Institutional, Dealerweb and Tradeweb Direct platforms. We are dependent on our dealer clients to support our marketplaces by providing liquidity on our trading platforms, and certain of our dealer clients may account for a significant portion of our trading volume. Market knowledge and feedback from these dealer clients have also been important factors in the development of many of our offerings and solutions. Our client sectors are continuing to become more interwoven and we believe we are well positioned to deliver the benefits of cross-marketplace network effects. Many of our asset manager, hedge fund, insurance, central bank/sovereign entity and regional dealer clients actively trade multiple products on our platforms. In addition, many of the commercial banks and dealers providing liquidity on Tradeweb Institutional are also active traders on Dealerweb, our wholesale platform, and provide odd-lot inventory for our retail client sector. We believe that this overlapping of client sectors and asset classes will continue and, in the long-term, will eliminate the distinctions across institutional, retail and wholesale channels. Given our technological capabilities, the diversity of our client sectors and the breadth of our products and trading protocols, we believe we are well positioned to capitalize on this emerging trend. Institutional Tradeweb Institutional offers dealer-to-client and all-to-all trading and related solutions to more than 1,950 liquidity-taking clients. Our clients include leading asset managers, hedge funds, insurance companies, regional dealers and central banks/sovereign entities. The Tradeweb Institutional platform serves 90% of the world’s largest 100 asset managers, over 80% of the top 25 insurance companies and over 60 central banks/sovereign entities with more than 200 dealers providing liquidity. Tradeweb Institutional offers trading in a wide variety of products, including U.S. Treasuries, European government bonds, TBA MBS, global interest rate swaps, global corporate bonds and ETFs, among others. Our trading protocols include RFQ, Request-for-Market, Request-for-Stream, list trading, compression, blast all-to-all, Click-to-Trade, portfolio trading and inventory-based. Wholesale We provide fully electronic, hybrid and voice trading for the wholesale community on our Dealerweb platform. Our clients include more than 300 dealers and financial institutions with more than 190 actively trading on our electronic and hybrid markets. Nearly all of our electronic and hybrid dealer clients also trade on the Tradeweb Institutional and Tradeweb Direct platforms. Wholesale’s leading markets include TBA MBS, specified pools, other securitized products, global credit products, U.S. Treasuries, repurchase agreements, U.S. dollar-denominated swaps, U.S. ETFs and U.S. equity derivative products. Our electronic trading protocols include directed streams, central limit orderbook and session-based trading. We are well positioned to facilitate and capitalize on the continued transition of wholesale client trading from voice or hybrid trading to fully electronic trading. To that end, we have had over 90% growth in the number of e-participants on our wholesale client sector markets since 2016. Retail Tradeweb Direct, our regulated Alternative Trading System (“ATS”), offers financial advisors and their retail clients access to micro-lot liquidity provided by our network of broker-dealers. Tradeweb Direct serves over 50,000 financial advisors at approximately 250 retail brokerage and advisory firms. In addition, certain Tradeweb Direct clients provide access to over 170,000 retail clients through white-labeled, web-based front ends. Tradeweb Direct also provides access to its ATS to large and middle-market asset managers. Tradeweb Direct offers trading in a range of products, including U.S. corporate bonds, Treasuries, municipal bonds, structured products and certificates of deposit (CDs), using our Click-to-Trade, inventory-based and RFQ trading protocols. Participants on Tradeweb Direct have the ability to connect to our marketplaces via workstations or APIs or through access to websites that are white-labeled for our clients. Our Asset Classes and Products We offer efficient and transparent trading across a diverse range of asset classes: • Rates : We facilitate trading in a broad range of cash and derivatives rates products, including major government securities, such as U.S. Treasury securities and European government bonds, mortgage-backed securities, interest rate swaps and agency/supranational securities and other rates products. • Credit : We offer deep pools of liquidity for our clients in cash and derivatives credit products, including U.S. and European high grade and high yield bonds, China bonds, municipal bonds, index, single name and sovereign credit default swaps and other credit products. 16 Table of Contents • Equities : We offer trading in a range of cash and derivatives equities products, including global ETFs, equity derivatives and other equities products. • Money Markets : We offer trading in a broad range of cash money market products, including commercial paper, agency discount notes, repurchase agreements, certificates of deposit and Treasury bills and other money markets products.

By region: • We serve more than 1,500 clients in the Americas across North, Central and South America. • We serve more than 700 clients in EMEA across Europe, the Middle East and North Africa. • We serve more than 300 clients in APAC across Asia, the Pacific, Oceania and the Indian sub-continent. In addition, we currently support trading across over 25 currencies globally. We believe our platforms, technology and solutions have made trading in markets globally more efficient and transparent. Furthermore, our expertise in multiple jurisdictions positions us as a partner of choice as our clients expand their trading operations to new geographies. As the global markets move to electronic trading, we expect to be at the forefront of this change. Our Solutions We provide clients with solutions across the trade lifecycle including pre-trade data and analytics, intelligent trade execution, straight-through processing and post-trade data, analytics and reporting. • Pre-Trade Data and Analytics : We provide clients with accurate, real-time market data and streaming price updates across more than 50 products. Major financial publications across the globe reference our market data. Our real-time market data services include major government bonds, corporate bonds, mortgage-backed securities, fixed income derivatives and money markets. For example, data and analytics power our Automated Intelligent Price, or Ai-Price, functionality, which delivers benchmark pricing and insights for over 26,000 U.S. corporate bonds. We integrate directly with order management systems allowing for order entry and pre-trade compliance and risk analysis. Clients are also able to perform credit checks for cleared derivatives trading — either with limits on our system or through connectivity to the futures commission merchants. 17 Table of Contents In addition, we provide LSEG with certain real-time market data feeds for multiple fixed income and derivatives products under a license pursuant to which LSEG distributes such market data to its customers on its platforms and through direct feeds. • Trade Execution : Trade execution is at the core of our business. We provide marketplaces and tools that facilitate trading by our clients and streamline their related workflows. Our market specialists and technology team work closely with our clients to continuously innovate and improve their trading practices. The trading protocols we currently offer on our platforms include: • Request-for-quote. Our multi-dealer request-for-quote, or RFQ, protocol provides institutional clients with the ability to hold a real-time auction with multiple dealers and select the best price. RFQ was pioneered by Tradeweb in 1998 and has been deployed across all of our rate markets, including government bonds, mortgage-backed securities and U.S. agencies, and our other asset classes. The RFQ is a fully-disclosed trading protocol — both buy-side and sell-side names are known prior to execution. Multi-dealer RFQ assists clients with achieving best execution. • Request-for-market. Our request-for-market, or RFM, protocol provides institutional clients with the ability to request a two-sided market from a particular dealer. This mirrors the approach of a client calling a specific trader for market prices and rates before showing the direction they want to trade. The RFM protocol has been effective in some of our newer markets, including credit default swap indices, where it is integrated with the RFQ and click-to-trade protocols on a single trading screen. • Request-for-stream. Our request-for-stream, or RFS, protocol allows multiple dealers to show clients continuously updating rates, in line with market movements, during a client’s request window. • List trading. Used by clients with multiple transactions to complete, our list trading protocol is a highly efficient workflow tool. By executing many trades at once, clients can request prices from multiple dealers to extract the best price and complete the hedging of the trades at one time, saving significant manual effort compared to executing on the telephone. • Compression . Clients utilize our interest rate swap compression tool as an efficient means to reduce the number of line items they have outstanding at a clearinghouse by netting offsetting positions in a single transaction. This functionality allows clients to submit up to 250 line items to liquidity providers for simultaneous list pricing, which they can execute, clear and report in one transaction, reducing both their risk and clearing costs. The Tradeweb compression tool is flexible and versatile in design allowing clients to adapt the tool to their workflow and customize for non-standard/bespoke swaps. • Blast all-to-all. Our Blast all-to-all, or A2A, protocol allows clients to send RFQ trade inquiries to all market participants in a given market and receive responses for executions. Trades are exposed to all liquidity providers simultaneously to broaden their liquidity sources. Blast A2A is currently used by our institutional clients in our global credit marketplaces, including U.S. high grade, U.S. high yield, European credit products and other corporate bonds. The Blast A2A functionality provides alert and inquiry monitors so participants are notified of trading opportunities. Clients can send single or list trade inquiries and can receive responses for full or partial fills. Clients can also leverage our AiEX tool in conjunction with this trading protocol. • Click-to-trade. Our click-to-trade, or CTT, protocol enables a liquidity-taking client to view a set of prices in real-time and click on the price and the dealer with whom they wish to execute. This trading protocol is especially popular with clients that are looking to view a range of executable, real-time prices across dealers. • Portfolio Trading . To support rebalancing of passive portfolios and ETFs, our portfolio trading solution allows clients to obtain competitive prices and trade on net present value on a full basket of securities. • Session-based . Sweep, our session-based trading protocol, allows clients to manage inventory and balance sheets by entering orders to be matched against opposite orders at a specified time and price, concentrating market liquidity to a particular point in time. This protocol leverages our broker relationships, technology, and pricing from the overall Tradeweb network to fill the gap between voice brokering and fully electronic order book trading. 18 Table of Contents • Central Limit Order Book. Our central limit order book, or CLOB, is a continuous electronic protocol that allows clients to trade on firm bids and offers from other market participants, as well as enter their own resting bids and offers for display to the market participants, typically anonymously. • Directed streams. Our directed streams protocol, which is currently used by our wholesale clients in the On-The-Run U.S. Treasury marketplace, gives clients an efficient alternative to traditional voice and order book trading. Liquidity-taking and liquidity-providing clients can establish data-driven, customized bilateral trading relationships that deliver real-time price discovery and high quality execution. In this matched principal model, clients can connect to a single platform to transact with multiple pools of directed liquidity. ◦ Inventory-based. Our inventory-based protocol allows liquidity-providing clients to submit a range of bids and offers for particular securities that a counterparty can then look to execute on. These prices are not necessarily updated in real-time but provide a good indication of where the counterparty is likely to complete the trade. This protocol is most commonly deployed in less liquid, security-specific marketplaces, such as certain credit and money markets marketplaces. ◦ Rematch. Our Rematch protocol allows dealers to send accepted, but unmatched orders from a Sweep session to the all-to-all network as an anonymous RFQ. For a pre-set period of time, sell-side participants create a second opportunity to trade a given security with a larger and more diverse set of counterparties. Rematch connects our wholesale liquidity to our institutional and retail liquidity pools. ◦ Voice. Voice-brokered products in our wholesale client sector include, among other products, U.S. Treasuries, MBS, municipal bonds and repurchase agreements. Our voice brokers provide anonymity and insight for sell side traders and give us valuable high-touch relationships and market understanding and access. Tradeweb Automated Intelligent Execution, or AiEX, is an innovative automated trading technology that allows clients to execute large volumes of trade tickets at a high speed using pre-programmed execution rules that are tailored to the client’s trading strategy. Clients use AiEX to efficiently automate high volumes of small, basic trades to free up time and create capacity. In addition, clients apply AiEX to more complex execution strategies to open up new trading opportunities. The trading benefits of AiEX include efficient accelerated execution, better optimization to fine-tune dealer selection and enhanced automated compliance. • Trade Processing : Our trade processing technology allows our clients to increase productivity, reduce risk and improve overall performance. Our post-trade solutions allow clients to allocate their electronic or phone-executed trades electronically, including storing and communicating organizational and sub-account settlement, identity and confirmation preference information for processing trades. Our post-trade solutions also make it easier for clients to communicate trade settlement information to dealers, prime brokers, fund administrators and confirmation vendors. Additionally, clients can send trades to clearinghouses and reporting in real-time through third-party middleware or Tradeweb developed direct links. We work side by side with numerous industry partners to provide direct server-to-server connections. By eliminating manual re-entry of trade and allocation information, our solutions assist clients in reducing failed trades and saving time, effort and money. • Post-Trade Data, Analytics and Reporting : Our comprehensive post-trade services include transaction cost analysis, or TCA, best execution reporting and client performance reports. These powerful tools provide our clients with ways to measure and optimize their trade performance. Our TCA tools monitor the cost effectiveness and quality of execution of trading activities for trades executed on or off Tradeweb. Our post-trade performance reports provide a summary of trading activity including detailed exception reports, price benchmarking and peer group comparisons. In partnership with FTSE Russell, we also provide U.S. Treasury, UK Gilt and European government bond closing prices in a manner consistent with the International Organization of Securities Commissions (“IOSCO”) principles and United Kingdom (“UK”) and European Union (“EU”) Benchmark Regulation (“BMR”). These reference prices can be used for asset valuation, trade at close and as reference rates in derivatives contracts. To support MiFID II regulatory obligations, we operate an APA reporting service in the UK and EU to allow clients to meet post-trade transparency requirements for off-venue or OTC trading activity. Our APA service provides regulatory pre-trade and post-trade reporting across multiple asset classes, including for products not offered by Tradeweb. The APA service also provides venue reporting for clients for LSEG’s FX trading venues. 19 Table of Contents Sales and Marketing We sell and promote our offerings and solutions using a variety of sales and marketing strategies. Our sales organization, which is generally not commission based, follows a team-based approach to covering clients, deploying our product and regional expertise as best dictated by evolving market conditions. The team has historically been organized by client sector and then by region, but as markets have converged, we have increasingly leveraged our global and cross-product expertise to drive growth. Our sales team, which works closely with our technology team, is responsible for new client acquisition and the management of ongoing client relationships to increase clients’ awareness, knowledge and usage of our trading platforms, new product launches, information and data services and post-trade services. Our sales team is also responsible for training and supporting new and existing clients on their use of our platforms and solutions and for educating clients more broadly on the benefits of electronic trading, including how to optimize their trading performance and efficiency through our various trading protocols. Given the breadth of our global client network, trading volume activity and engagement with regulatory bodies, we regularly work to help educate market participants on market trends, the impact of regulatory changes and technology advancements. Our senior executives often provide insight and thought leadership to the industry through conversations with the media, appearances at important industry events, roundtables and forums, submitting authored opinion pieces to media outlets and conducting topical webinars for our clients. We believe this provides a valued service for our constituents and enhances our brand awareness and stature within the financial community. Additionally, we employ various marketing strategies to strengthen our brand position and explain our offerings, including through our public website, advertising, digital and social media, earned media, direct marketing, promotional mailings, industry conferences and hosted events. Competition The markets for our solutions continue to evolve and are competitive in the asset classes, products and geographies in which we operate. We compete with a broad range of market participants globally. Some of these market participants compete in a particular market, while select others compete against the entire spectrum of our offerings and solutions. In addition, there are other companies that have the platform breadth and global reach that we provide. We believe that our comprehensive offerings, global reach, culture of collaboration and broad network increasingly differentiate us from other market participants. We primarily compete on the basis of client network, domain expertise, breadth of offerings and solutions and ease of integration of our platforms with our client’s technology, as well as the quality, reliability, security and ease of our platforms and solutions. We face six main areas of competition: • Other electronic trading platforms : We compete with a number of other electronic trading venues. These include MarketAxess, Bloomberg, ICE (Bondpoint, TMC Bonds, Creditex), Trumid, TP ICAP (Liquidnet) and others in the credit and municipal markets; Bloomberg, Euronext (MTS), CME Group (NEX Group), BGC Partners (Fenics), MarketAxess (LiquidityEdge), GLMX and others in the rates and derivatives markets; and Virtu (RFQ-hub) and Bloomberg in the equities and ETF markets. • Exchanges : In recent years, exchanges have pursued acquisitions that have put them in competition with us. For example, ICE acquired BondPoint and TMC Bonds, retail-focused platforms, and Interactive Data Corporation (“IDC”), a provider of fixed income data, in an effort to expand its portfolio of fixed income products and services. CME Group and CBOE also operate exchanges that compete with us. Exchanges also have data and analytics relationships with several market participants, which increasingly put their offerings in direct competition with Tradeweb. • Inter-dealer brokers : We compete with inter-dealer brokers, particularly in our wholesale markets in products such as MBS, U.S. Treasuries, U.S. repo and products traded on Swap Execution Facilities (“SEFs”). Major competitors include TP ICAP, BGC Partners and Tradition. Many of these firms also offer voice, electronic and hybrid trading protocols. As larger, full service inter-dealer brokers have consolidated, numerous boutique firms and alternative electronic start-ups are attempting to capture select markets. • EMS and OMS providers: There are various providers of execution management services (“EMS”) and order management services (“OMS”) that have announced plans to offer aggregation of trading venue liquidity, as well as direct-to-dealer fully electronic trading solutions. • Single-bank systems : Major global and regional investment and commercial banks offer institutional clients electronic trade execution through proprietary trading systems. Many of these banks expend considerable resources on product development, sales and support to promote their single-bank systems. 20 Table of Contents • Dealers : Many of our markets are still traded through traditional voice-based protocols. Institutional investors have historically purchased fixed-income securities, large blocks of equity securities, or ETFs, or entered into OTC derivative transactions, by telephoning sales professionals at dealers. We face competition from trading conducted over the telephone between dealers and their institutional clients. • Market data and information vendors : Market data and information providers, such as Bloomberg, IDC (now part of ICE) and IHS Markit, have a pervasive presence across the financial trading community. Their data and pre- and post-trade analytics compete with offerings we provide to support trading on our marketplaces. We face intense competition, and we expect competition with a broad range of competitors to continue to intensify in the future. See Part I, Item 1A. – “Risk Factors — Risks Relating to Market and Industry Dynamics and Competition — Failure to compete successfully could materially adversely affect our business, financial condition and results of operations.” Proprietary Technology For more than 25 years, we have collaborated with our clients to continually innovate and evolve with the structure of our markets. This collaboration enables us to remain agile across client sectors, geographies, asset classes and products providing speed to market and a distinct cost and innovation advantage to our clients. Critical to our ability to collaborate with clients and remain at the forefront of evolving market trends is our team of over 350 technologists, which works closely with our client, product and sales teams and has deep market knowledge and domain expertise. This knowledge and expertise not only allows us to address client demand but also to focus on those solutions that can be scaled across client sectors, asset classes and trading protocols. Our systems are built to be scalable, flexible and resilient. Our core software solutions span the trading lifecycle and include pre-trade analytics, trade execution and post-trade data, analytics and reporting, connectivity and straight-through processing. A significant portion of our operating budget is dedicated to system design, development and operations in order to achieve high levels of overall system performance. We continually monitor our performance metrics and upgrade our capacity configurations and requirements to handle anticipated peak trading activity in our highest volume products. The key aspects of our proprietary technology infrastructure include facilitating client-driven innovation, launching new solutions quickly and investing in talent, machine learning and AI capabilities. These aspects of our technology lead to the following: • Nimble product development in collaboration with clients : Our approach to product development facilitates continuous releases of important product features. This allows us to be opportunistic in what we decide to release at any point in time and inject newly discovered opportunities into the trade lifecycle. We have designed our platforms to be component-based and modular. New components can be built quickly and have detailed monitoring and command capabilities embedded. • Scalable architecture : Our scalable architecture was designed to address increased trading activities and evolving market structures in a cost efficient manner. Furthermore, the diversity and breadth of our platforms allow us to expand our capabilities across new markets. We use third-party data centers to more flexibly manage our capacity needs and costs, as well as to leverage security, network and service capabilities. • Strong business continuity and disaster recovery planning : We continue to regularly evaluate and enhance our business continuity plans in place in the event of a significant business disruption or disaster recovery situation to ensure the resilience of critical systems required for normal operations and the safety of all employees. The plans cover a range of scenarios and adhere to industry standards and regulatory mandates as outlined by the Interagency Paper on Sound Practices to Strengthen the Resilience of the U.S. Financial System, the SEC’s Regulation Systems Compliance and Integrity, Commodity Futures Trading Commission (“CFTC”) rules concerning system safeguards and other agencies and entities. Activities covered by the plans include the primary responsible parties at Tradeweb, actions to restore essential systems and applications with target recovery times to accomplish all stated objectives and communications to staff, partners, clients and regulators. The plans are periodically updated based on the most relevant threats to operations and tested to ensure effectiveness during emergency conditions. We also maintain redundant networks, hardware, data centers and alternate operational facilities to address interruptions. We have ten datacenters across the United States, the UK , Japan and Austrialia. Our data center infrastructure is designed to be resilient and responsive with built-in redundancies. 21 Table of Contents • Ongoing security, system monitoring and alerting : We prioritize security throughout our platforms, operations and software development. We make architectural, design and implementation choices to structurally address security risks, such as logical and physical access controls, perimeter firewall protection and embedded security processes in our systems development lifecycle. Our cyber security program is based on a combination of ISO/ICE 27001 principles, the National Institute of Standards and Technology Cybersecurity Framework and industry best practices. Our Chief Information Security Officer leads a qualified cybersecurity team in assessing, managing and reducing material risks from cybersecurity threats to protect critical operations and delivery of service. We continuously monitor connectivity, and our global operations team is alerted if there are any suspect events. See Part I, Item 1C. – “Cybersecurity – Governance” for further detail regarding our cybersecurity risk management, strategy and governance structure. Intellectual Property Like most companies that develop technology in-house, 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. To that end, we have patents or patents pending in the United States and other jurisdictions covering significant trading protocols and other aspects of our trading system technology. In addition, we own, or have filed applications for, the rights to trade names, trademarks, copyrights, domain names and service marks that we use in the marketing of our platforms and solutions to clients. We have registered for trademarks in many of our markets, including our major markets, with registrations pending in others. Trademarks registered include, but are not limited to, “Tradeweb,” “Dealerweb,” and “Tradeweb Direct.” We also enter into written agreements with third parties, employees, clients, contractors and strategic partners to protect our proprietary technology, processes and other intellectual property, including agreements designed to protect our trade secrets. Examples of these written agreements include third-party non-disclosure agreements, employee non-disclosure and inventions assignment agreements, licensing agreements and restricted use agreements. Regulation Many aspects of our business are subject to regulation in a number of jurisdictions, including the United States, the UK, the Netherlands, France, Germany, Japan, Hong Kong, Singapore, Australia and the Dubai International Financial Centre (“DIFC”). In these jurisdictions, government regulators and self-regulatory organizations oversee the conduct of our business, and have broad powers to promulgate and interpret laws, rules and regulations that may serve to restrict or limit our business. As a matter of public policy, these regulators are tasked with ensuring the integrity of the financial and securities markets and protecting the interests of investors in those markets generally. Rulemaking by regulators, including resulting market structure changes, has had an impact on our business by directly affecting our method of operation and, at times, our profitability, as well as indirectly by imposing costs in the form of increased compliance, personnel, and technology needs in order to comply with relevant laws and regulations. As registered trading platforms, broker-dealers, introducing brokers and other types of regulated entities as described below, certain of our subsidiaries are subject to laws, rules and regulations (including the rules of self-regulatory organizations) that cover all aspects of their business, including manner of operation, system integrity, anti-money laundering and financial crimes, handling of material non-public information, safeguarding data, capital requirements, reporting, record retention, market access, licensing of employees and the conduct of officers, employees and other associated persons. Regulation can impose, and has imposed, obligations on our regulated subsidiaries, including our broker-dealer subsidiaries. These increased obligations require the implementation and maintenance of internal practices, procedures and controls, which have increased our costs. Many of our regulators, as well as other governmental authorities, are empowered to bring enforcement actions and to conduct administrative proceedings, examinations, inspections and investigations, which may result in increased compliance costs, penalties, fines, enhanced oversight, increased financial and capital requirements, additional restrictions or limitations, censure, suspension or disqualification of the entity and/or its officers, employees or other associated persons, or other sanctions, such as disgorgement, restitution or the revocation or limitation of regulatory approvals. Whether or not resulting in adverse findings, regulatory proceedings, examinations, inspections and investigations can require substantial expenditures of time and money and can have an adverse impact on a firm’s reputation, client relationships and profitability. From time to time, we and our associated persons have been and are subject to routine reviews, none of which to date have had a material adverse effect on our businesses, financial condition, results of operations or prospects. As a result of such reviews, we may be required to amend certain internal structures and frameworks, such as our operating procedures, systems and controls. 22 Table of Contents The regulatory environment in which we operate is subject to constant change. We are unable to predict how certain new laws and proposed rules and regulations will be implemented or in what form, or whether any changes to existing laws, rules and regulations, including the interpretation, implementation or enforcement thereof or a relaxation or amendment thereof, will occur in the future. We believe that uncertainty and potential delays around the final form of certain new rules and regulations may negatively impact our clients and trading volumes in certain markets in which we transact, although a relaxation of or the amendment of existing rules and requirements could potentially have a positive impact on certain markets. While we generally believe the net impact of the laws, rules and regulations may be positive for our business, it is possible that unintended consequences may materially adversely affect us in ways yet to be determined. See Part I, Item 1A. – “Risk Factors — Risks Relating to Legal, Regulatory and Tax Considerations — Our business, and the businesses of many of our clients, could be materially adversely affected by new laws, rules or regulations or changes in existing laws, rules or regulations, including the interpretation and enforcement thereof.” U.S. Regulation In the United States, the SEC is the federal agency primarily responsible for the administration of the federal securities laws, including adopting and enforcing rules and regulations applicable to broker-dealers. Two of our broker-dealers operate alternative trading systems subject to the SEC’s Regulation ATS, which includes certain specific requirements and compliance responsibilities in addition to those faced by broker-dealers generally. Broker-dealers are also subject to regulation by state securities administrators in those states in which they conduct business or have registered to do business. We are also subject to the various anti-fraud provisions of the Securities Act, the Exchange Act, the Commodity Exchange Act, certain state securities laws and the rules and regulations promulgated thereunder. We also may be subject to vicarious and controlling person liability for the activities of our subsidiaries and our officers, employees and affiliated persons. The CFTC is the federal agency primarily responsible for the administration of federal laws governing activities relating to futures, swaps and other derivatives (but excluding security-based swaps) including the adoption of rules applicable to SEFs. Our SEFs are subject to regulations that relate to trading and product requirements, governance and disciplinary requirements, operational capabilities, surveillance obligations and financial information and resource requirements, including the requirement that they maintain sufficient financial resources to cover operating costs for at least one year. Much of the regulation of broker-dealers’ operations in the United States has been delegated to self-regulatory organizations. These self-regulatory organizations adopt rules (which are generally subject to approval by the SEC) that govern the operations of broker-dealers and conduct periodic inspections and examinations of their operations. In the case of our U.S. broker-dealer subsidiaries, the principal self-regulatory organization is the Financial Industry Regulatory Authority, Inc. (“FINRA”). Accordingly, our U.S. broker-dealer subsidiaries are subject to both scheduled and unscheduled examinations by the SEC and FINRA. In addition, our broker-dealers’ municipal securities-related activities are subject to the rules of the Municipal Securities Rulemaking Board (“MSRB”). In connection with our introducing broker-related activities, we are also subject to the oversight of the National Futures Association (“NFA”), a self-regulatory organization that regulates certain CFTC registrants. Following the 2008 financial crisis, legislators and regulators in the United States adopted new laws and regulations, including the Dodd-Frank Act. Various rules and regulations were promulgated following the financial crisis, such as the Volcker Rule and additional bank capital and liquidity requirements. In addition, Title VII of the Dodd-Frank Act (“Title VII”) amended the Commodity Exchange Act and the Exchange Act to establish a regulatory framework for swaps, subject to regulation by the CFTC, and security-based swaps, subject to regulation by the SEC. The CFTC has completed the majority of its regulations in this area, most of which are in effect. The SEC has also finalized many of its security-based swap regulations. Among other things, Title VII rules require certain standardized swaps to be cleared through a central clearinghouse and/or traded on a designated contract market or SEF, subject to various exceptions. Title VII also requires the registration and regulation of certain market participants, including SEFs, and requires SEFs to maintain robust front-end and back-office information technology capabilities. The SEC is charged with regulations for “security-based swaps” (i.e., swaps based on certain types of securities or loans). In late 2023, the SEC adopted registration requirements for entities that act as security-based swap execution facilities (“SBSEFs”). We expect that one or more of our subsidiaries will register in this capacity with the SEC and, as such, will become subject to further new extensive regulation at an entity level as well as new requirements specifically applicable to the business as it relates to security-based swaps. We anticipate that implementation of these requirements will be substantially similar to requirements implemented as a result of operating as a CFTC-registered SEF, but the implementation will likely result in new challenges and oversight risk. 23 Table of Contents The regulatory environment in the U.S. continues to evolve and while legislation to roll-back key pieces of the Dodd-Frank Act in an effort to loosen certain regulatory restrictions on financial institutions has been issued, the industry continues to be more heavily regulated than it was prior to the 2008 financial crisis. While it is still largely unknown at this time to what extent new legislation will be passed into law or whether pending or new regulatory proposals will be adopted or modified, or what effect such passage, adoption or modification will have, whether positive or negative, on our industry, our clients or us, both the SEC and the CFTC have issued a number of regulatory proposals and we may continue to see the same level of activity by these two regulators in the future. For example, in August 2022, the CFTC issued a final rule modifying the swap clearing requirement in support of the transition from LIBOR and other Interbank Offered Rates to Alternative Reference Rates and Tradeweb SEF LLC filed and received approval on July 7, 2023 to include certain swaps referencing risk-free rates as designated made available to trade products. Additionally, the SEC has recently conducted a review of the regulatory framework for fixed-income electronic trading platforms for the purpose of evaluating the potential regulatory gaps that may exist among such platforms, including ours, with respect to access to markets, system integrity, surveillance, and transparency, among other things. In recent years, the SEC proposed rules that would expand Regulation ATS and Regulation SCI to capture alternative trading systems (“ATS”) that trade government securities and amend the SEC rule regarding the definition of an “exchange” to include Communication Protocol Systems, such as our RFQ protocols. In April 2023, the SEC proposed separate, specific rules that would update the requirements of Regulation SCI and expand the number and types of entities that must comply with Regulation SCI. In connection with these proposed rules, we expect that we will have to operate additional trading protocols in compliance with Regulation ATS and Regulation SCI. It is unknown at this time to what extent new legislation will be passed into law or whether pending or new regulatory proposals will be adopted or modified, or what effect such passage, adoption or modification will have, whether positive or negative, on our industry, our clients or us. The SEC also adopted final rules on December 13, 2023 regarding central clearing of certain secondary market repurchase and reverse repurchase transactions and secondary market purchase and sale transactions involving U.S. Treasury securities. Although the final rule was more limited in scope than the initial rule proposal, this central clearing mandate will impact certain market participants who do not clear today, and some have expressed concerns about the potential impact of additional clearing costs that may impact liquidity. While we expect this change will increase our own platform efficiency and potentially create greater electronification of trading, it is still unknown at this time the full impact of this change, and what effect it will have, whether positive or negative, on our industry, our clients or us. Non-U.S. Regulation Outside of the United States, we are currently regulated by: the Financial Conduct Authority (“FCA”) in the UK, the De Nederlandsche Bank (“DNB”) and the Netherlands Authority for the Financial Markets (“AFM”), Autorité Des Marchés Financiers (“AMF”) and Autorité de contrôle prudentiel et de resolution (“ACPR”) in France, Bundesanstalt für Finanzdienstleistungsaufsicht (“BaFin”) in Germany, the Japan Financial Services Agency (the “JFSA”), the Japan Securities Dealers Association (the “JSDA”), the Securities & Futures Commission (the “SFC”) of Hong Kong, the Monetary Authority of Singapore (the “MAS”), the Australian Securities and Investment Commission (the “ASIC”), the Comisión Nacional Bancaria y de Valores (the “CBNV”) in Mexico, the Swiss Financial Market Supervisory Authority (“FINMA”), the Investment Industry Regulatory Organization of Canada and provincial regulators in Canada and the Dubai Financial Services Authority (the “DFSA”) in the DIFC. The FCA’s strategic objective is to ensure that the UK’s markets function well and its operational objectives are to protect consumers, to protect and enhance the integrity of the UK financial system and to promote effective competition in the interests of consumers. It has investigative and enforcement powers derived from the Financial Services and Markets Act 2000 (“FSMA”) and subsequent legislation and regulations. The FCA is responsible for supervision of our conduct and prudential compliance. Subject to section 178 of FSMA, individuals or companies that seek to acquire or increase their control in a firm that the FCA regulates is required to obtain prior approval from the FCA. The legal framework in the Netherlands for financial undertakings is predominantly included in the Dutch Financial Supervision Act (Wet op het financieel toezicht or “FSA”). The AFM, like the DNB, is an autonomous administrative authority with independent responsibility for fulfilling its supervisory function. Pursuant to section 2:96 of the FSA, the AFM authorizes investment firms. The AFM is legally responsible for business supervision. The DNB is responsible for prudential supervision. The purpose of prudential supervision is to ensure the solidity of financial undertakings and to contribute to the stability of the financial sector. Holders of a qualifying holding (in short, shareholdings or voting rights of 10% or more) must apply to the DNB for a declaration of no objection and satisfy the applicable requirements pursuant to section 3:95 of the FSA. The DNB and the AFM co-operate under the provisions of the FSA and have concluded a covenant on the co-operation and co-ordination of supervision and other related tasks. 24 Table of Contents Much of our derivatives volume continues to be executed by non-U.S. based clients outside the United States and is subject to local regulations. In particular, the EU has enhanced the existing laws and developed new rules and regulations targeted at the financial services industry, including MiFID II and Markets in Financial Instruments Regulation (“MiFIR”), which were implemented in January 2018 and which introduced significant changes to the EU financial markets, including the fixed income and derivative markets, designed to facilitate more efficient markets and greater transparency for participants. During 2023, the European Securities and Markets Authority (“ESMA”), the EU’s financial markets regulator and supervisor, announced a shift in its Union Strategic Supervisory Priorities (“USSPs”), introducing cyber risk and digital resilience as key areas of focus alongside environmental, social and governance disclosures. The strategy takes into account the key priorities of the EU in the area of financial services and aims to address the most significant risks linked to EU financial markets. It is structured around the following key areas: effective financial markets and financial stability, supervision and supervisory convergence, retail investor protection, sustainable finance and technological innovation and increased use of data. With this new priority, EU supervisors will put greater emphasis on reinforcing firms’ information and communication technology (“ICT”) risk management surrounding the use of financial technology systems (including but not limited to trading venue technologies) through close monitoring and supervisory actions, building new supervisory capacity and expertise. The new USSP will come into force in 2025, at the same time as the Digital Operational Resilience Act. This timeline is intended to provide supervisors and firms in member states with sufficient time to prepare for compliance with the new regulatory requirements. Meanwhile, ESMA and national competent authorities (“NCAs”) will carry out preparatory work planning and shaping the supervisory activities to undertake this priority. The USSPs are an important tool through which ESMA coordinates and focuses supervisory action with NCAs across the EU on specific topics. The Digital Operational Resilience Act (“DORA”) is a new EU framework which aims to enhance and harmonize the digital operational resilience and cyber security of entities across the EU financial sector. Under DORA firms that are in scope will need to adopt a broader business view of resilience, with accountability clearly established at the senior management level. DORA consists of the following key pillars: ICT risk management requirements, reporting of ICT incidents, testing programs covering ICT tools, systems and processes, ICT third party risk management and an oversight framework for critical ICT third-party service providers. Capital Requirements Certain of our subsidiaries are subject to jurisdiction specific regulatory capital requirements, designed to maintain the general financial integrity and liquidity of a regulated entity. In general, they require that at least a minimum amount of a regulated entity’s assets be kept in relatively liquid form. Failure to maintain required minimum capital may subject a regulated subsidiary to a fine, requirement to cease conducting business, suspension, revocation of registration or expulsion by the applicable regulatory authorities, and ultimately could require the relevant entity’s liquidation. As of December 31, 2023, each of our regulated subsidiaries had maintained sufficient net capital or financial resources to at least satisfy their minimum requirements. See Note 19 – Regulatory Capital Requirements to our audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Regulatory Status of Tradeweb Entities Our operations span jurisdictions across North America, South America, Europe, Asia, Australia and the Middle East, and we operate through various regulated entities. The current regulatory status of our regulated entities is described below. Tradeweb LLC is a SEC-registered broker-dealer and a member of FINRA and MSRB. Tradeweb LLC is also a CFTC-registered introducing broker and a member of NFA. Tradeweb LLC relies on the international dealer exemption in the Canadian provinces of Ontario, Alberta, British Columbia, New Brunswick, Nova Scotia, Quebec, Saskatchewan and Manitoba and is recognized as a foreign trading venue in Switzerland. Dealerweb Inc. is a SEC-registered broker-dealer, operates an ATS and is a member of FINRA and MSRB. Dealerweb Inc. is also a CFTC-registered introducing broker and a member of NFA.

Human Capital In order to maintain our role as a leader in building and operating electronic marketplaces for our global network of clients, it is crucial that we continue to attract and retain top talent. To facilitate talent attraction and employee retention, we strive to make Tradeweb a diverse, inclusive and safe workplace. We firmly believe that a cared-for, proud, and diverse workforce will power our innovation into the future. We strive to provide opportunities for our employees to grow and develop in their careers, supported by strong compensation, benefits and health and wellness programs, and by initiatives that build connections between our employees and the communities in which we operate. 26 Table of Contents As of December 31, 2023, we had 1,179 employees, 815 of whom were based in the United States and 364 of whom were based outside of the United States. None of our employees are 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. Diversity, Equity and Inclusion We believe that diverse teams make better decisions and create greater long-term value, and we are committed to maintaining a safe and inclusive environment for everyone and attracting and retaining diverse talent at all levels. Our goal is to continue to strive for greater gender and ethnic diversity across the company, in accordance with applicable equal opportunity laws, to maintain and grow our culture of inclusiveness, education, acceptance and learning, and to ensure employees feel encouraged and equipped to be their genuine selves at work. Through our Diversity, Equity and Inclusion (“DE&I”) Committee, on which members of our executive team serve, including our Global Head of Human Resources and Head of Investor Relations, FP&A and Treasury, we raise awareness, provide a forum to discuss diversity and inclusion and promote a diverse and inclusive culture. We seek to involve employees at all levels in DE&I, including through recruitment, philanthropy and training. We also sponsor the Global Women’s Network, which provides skills-building, educational, and career-relevant programming for employees and brings topics affecting women in the workplace front and center. Our commitment to DE&I has been demonstrated through partnerships with approximately 18 organizations globally, including StreetWise Partners, Women’s Bond Club, TEAK, Hiring our Heroes, Emily K Center and Adaptive Growth Leadership in the U.S., and SEO, Big City Bright Future and Cowrie Scholarship Foundation in the UK. By focusing on employee volunteerism in these areas, our employees have the opportunity to take action and make a difference. We also seek to advance the interests of our stakeholders through DE&I initiatives. For example, in June 2022, we launched the Spotlight Dealer Diversity Program, designed to promote diverse dealers participating on our platforms, including woman-, veteran-, disabled- and minority-owned firms. The Spotlight Program was developed collaboratively with feedback from members of the buy-side and dealer communities to support our diverse dealer community through a combination of individual dealer profiles, direct consultation and other promotional programs designed to bring more visibility to diverse dealers operating in electronic markets. In addition, we enhanced our RFQ trading workflow for U.S. Institutional Credit to more prominently expose diverse dealer liquidity to our participating buy-side clients, further strengthening engagement between diverse dealers and buy-side users on the platform. We continue to work with our Spotlight participants to expand opportunities for doing business together. Since launch we have grown from 12 participating Spotlight Dealers to 21. In addition, we seek to cement our commitment to diversity at the intern, college graduate and experienced hire levels by leveraging relationships with a number of external organizations. These efforts all support our multi-layered strategy for recruiting and retaining diverse talent. Health and Well-Being The success of our business is fundamentally connected to the health, safety and wellness of our employees. We provide an evolving package of benefits and perks to employees (which varies by country and region), aiming to ensure our employees have access to comprehensive care relating to their physical and mental health and their family planning needs, as well as adequate time out of office for personal, vacation, sick and bereavement leave needs. Some examples of the initiatives we provide in certain countries include post-birth parental and adoptive parent leave, financial assistance in connection with eligible fertility treatment, adoption and surrogacy expenses, health and wellness speaker series, health club discounts and subsidized memberships through Healthkick and virtual health visits. Compensation and Benefits We provide robust compensation and benefits programs to help attract and retain talent and to meet the needs of our employees. In addition to salaries, these programs (which vary by country or region) include annual bonuses, stock awards, retirement savings plans, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, family leave, family care resources, flexible work schedules, employee assistance programs, including confidential counseling services for employees and their family members and tuition assistance, among many others. In addition to our broad-based equity award programs, we have used targeted equity-based grants with vesting conditions to facilitate retention of key personnel, particularly those with strong product and functional knowledge, critical technology and engineering skills and experience. 27 Table of Contents Talent Development We invest significant resources to develop and retain the talent needed to continue to build our position as a global leader in electronic marketplaces. We are focused on providing continuous opportunities for our employees to garner new knowledge and skills. Events and resources such as product and business updates, as well as other programs such as Lunch & Learns and Tradeweb U(niversity), which provides education courses on financial topics, are aimed at sharing information and improving our collective understanding of our industry and our clients’ needs. We sponsor a competitive summer internship program, from which we often make full-time hires, and provide assistance with numerous professional courses and qualifications through our tuition reimbursement program. Through our mentoring efforts and Tradeweb Achievers Program, we aim to strengthen our global culture of mentoring and developing our homegrown talent by equipping our senior leadership team with the tools and framework to share their professional experiences, motivate up-and-coming talent and build our future leadership pipeline. Our employee engagement programs provide employees with the resources they need to help develop themselves and our shared culture—celebrating our differences and common purpose as our people grow both as unique individuals and as a collective, positive force in the world. Tradeweb has established and supports a number of committees and affinity groups dedicated to improving our people’s lives at work and advancing their personal and professional development. These include the Tradeweb Global Women’s Network, Diversity Equity & Inclusion Network, Tradeweb Cares philanthropy group, Sustainability Action Network and the Working Parents Network. Community Involvement and Philanthropy We believe it is our responsibility to do our part to help the communities around the world where our employees live and work. We bring these opportunities to our employees through our philanthropy group, Tradeweb Cares, which focuses on corporate partnerships, encouraging employee volunteerism and matching of qualifying charitable contributions by our employees up to $1,000 per year per employee. We partner with many organizations around the world that are focused on the four pillars of our philanthropy strategy: ensuring equitable access to quality education and economic opportunity for all, supporting environmental conservation efforts to restore our planet, enriching and empowering social mobility in the communities where we live and work, and providing access to healthcare and disease prevention for our society’s most vulnerable. Corporate Sustainability – Environmental, Social and Governance Matters We are committed to doing our part to help financial markets move toward a more sustainable global financial system. In August 2023 we published our third annual Corporate Sustainability Report, which reports on our environmental, social and governance (“ESG”) goals and priorities as well as our progress towards those goals during calendar year 2022. While the reporting structure is relatively new, our strong foundation in ESG principles is not. We have long been committed to creating and fostering an inclusive workplace, celebrating our diverse employee base, providing transparency and innovation for our markets and ensuring transparency and validity for the data that propels them. Our long-term view encompasses ever more sustainable ways of working and investing as we forge the links between better serving markets and better serving the world. The Environment We are committed to understanding the full extent of our environmental impact and to working toward minimizing our global emissions footprint. We seek to better understand the environmental impact of our operations through measurable means, and to set attainable targets and timelines for environmental impact reporting, including the eventual setting of science-based targets for greenhouse gas emissions. While our business involves limited direct environmental risks, we will endeavor to make our operations and impact more sustainable over time. Our primary environmental goals have been to reduce our overall energy consumption and emissions where possible, and to move toward renewable energy coverage, or direct sourcing of renewable energy for our Scope 2 energy usage. To that end, we purchased Green-e U.S. Renewable Energy Certificates for our forecasted 2023 U.S energy usage and retired them in September of 2023. We also purchased Japan Non-Fossil Certificates for our forecasted energy usage from operations in Asia, which were retired at the end of 2023. This marks a step forward in our climate action plan, and an action toward our stated goal of covering our global usage with renewable energy. Tradeweb also responded to CDP for the first time, and published our inaugural Taskforce on Climate-Related Financial Disclosure (“TCFD”) report, each in 2023. We endeavor to continue to be transparent and robust in our environmental disclosure, marking important steps toward that goal with these two reporting items. 28 Table of Contents In April 2021, we joined the Climate Bonds Initiative’s (“CBI”) Partnership Programme. CBI is an international, investor-focused not-for-profit organization promoting investment in projects and assets necessary for a rapid transition to a low-carbon and climate-resilient economy. The Climate Bonds Standard and Certification Scheme (the “Scheme”) is a labeling scheme for bonds, loans and other debt instruments. The Scheme’s rigorous scientific criteria are intended to ensure consistency with the Paris Agreement’s goal of limiting global warming to 1.5 degrees Celsius above pre-industrial levels. The Scheme is used globally by bond issuers, governments, investors and the financial markets seeking to prioritize investments that genuinely contribute to addressing climate change. By partnering with CBI, we aim to promote the visibility and accessibility of Green Bond trading activity across a wide range of asset classes, and leverage CBI data to provide transparency and clarity around the Green Bond trading volumes and trends on our platforms. In 2023, CBI-screened Green Bond trading accounted for $292.0 billion of the total $303.6 billion in global Green Bond trading volume executed on Tradeweb (excluding ETF). This represents a trading volume increase of 46% from 2022, calculated using CBI-screened Green Bond alignment based on the CBI definition of ‘Green’ as of December 31, 2023 for both the 2023 and 2022 comparative period. We provide Green Bond highlights across our institutional platform, including Global Credit, European Government Bonds, Supranationals, Repurchase Agreements, China Bonds, and Convertibles, and have Green Bond search tools across asset classes on our Retail platform. We plan to continually increase the data available to our clients around Green Bonds, and intend to expand this data set to include other ESG - related securities including Social Bonds, Sustainability Bonds, and Sustainability-Linked Bonds. Our People and Communities We value and encourage diverse perspectives, and strive to cultivate a team with varied and robust ideas. We aim to give everyone the access and ability to grow as an individual and, eventually, a leader. For more information on how we support our people and help foster a diverse workforce, please see “ – Human Capital” above. Our Governance We have invested in strong and well-established governance structures across our global enterprise, led by a diverse Board of Directors that is deeply experienced in our business and highly focused on advancing our ESG strategies across the company. As part of that commitment, during 2020, we established an ESG Steering Committee comprised of senior level executives covering major business directives across the company. The ESG Steering Committee is an advisory board assembled to guide our focus, and ensure delivery on our thoughtful approach to integrating our ESG strategy into our business and operations. To support the implementation of our ESG strategy, a dedicated team was formed and has expanded to meet the needs of our growing strategy. The team head reports directly into our senior executive leadership team, which provides critical support for the integration of these initiatives across our business. At the Board level, the Nominating and Corporate Governance Committee is responsible for ESG oversight and guidance. The Compensation Committee has responsibility for oversight of human capital-related topics, including diversity, equity, and inclusion, and the Audit Committee has responsibility for oversight of external reporting of climate-related disclosures. Our Organizational Structure Tradeweb Markets Inc. was incorporated in Delaware in November 2018. As a result of the Reorganization Transactions completed in connection with the IPO, Tradeweb Markets Inc. became a holding company whose only material assets consist of its equity interest in Tradeweb Markets LLC and related deferred tax assets.
