Good morning, and welcome to Tradeweb's Q1 2022 Earnings Conference Call. As a reminder, today's call is being recorded and will be available for playback. To begin, I'll turn the call over to Head of Treasury, FP&A, and Investor Relations, Ashley Serrao. Please go ahead. Thank you and good morning. Joining me today for the call are our Chairman and CEO, Lee Olesky, who will review the highlights for the quarter and provide a business update. Our CEO-elect and President, Billy Hult, who will dive a little deeper into some growth initiatives, and our CFO, Sara Furber, who will review our financial results.

Please see the earnings release in the Form 10-Q to be filed with the SEC for additional information regarding the presentation of our historical results. Now let me turn the call over to Lee. Thanks, Ashley. Good morning, everyone, and thank you for joining our Q1 earnings call. 2022 has begun frantically with a combination of Fed tapering, global rate hikes, surging inflation, and the brutal war in Ukraine. These macro events have combined to spur higher global government bond yields, wider corporate bond spreads, and lower equity market valuations. Amidst this backdrop, we remain very engaged with our clients as they traded more than $1 trillion daily on average, setting new records. Importantly, these records translated into strong revenue growth as Tradeweb powered past $300 million in quarterly revenues for the first time in our history. As we review the quarter, we were especially pleased by the diversity of our growth across our global multi-asset class, multi-client, and multi-protocol business that we have built over the last 25 years. We had an excellent quarter where we achieved record revenues across US Treasuries, European government bonds, global swaps, U.S. and European credit, munis, global ETFs, and repo. This broad-based growth led to record results across our four asset classes and across our institutional and wholesale channels. It's also great to see the early pickup in our retail business, which produced its strongest revenue growth quarter since Q3 2019. Turning to slide four, record gross revenues of $311 million during the Q1 of 2022 were up 13.9% year-on-year on a reported basis, and 15.9% on a constant currency basis. This growth is in line with the 16% growth we produced over the last five years and is a testament to the durability of our revenue growth story across different macro environments. The revenue growth and the resulting scale translated into improved profitability relative to the full year 2021 as our Q1 Adjusted EBITDA margin increased to 51.6%. Turning to slide five, this quarter was marked by strong performance across all our asset classes, with rates and credit continuing to lead the way, accounting for 46% and 31% of our revenue growth, respectively. Specifically, rates posted a record quarter, driven by our continued growth across global government bonds and swaps. In cash rates, global government bond revenues were partially helped by healthy central bank issuance, higher volatility, and the addition of NFI. Swaps produced another quarterly revenue record with positive market share growth, while mortgage revenues declined. Credit posted a record quarter, driven by strong U.S. and European corporate credit and CDS trading. Equities accounted for 20% of our revenue growth, as record revenues were driven by institutional ETFs and our efforts to diversify and grow our other equity products. Money markets performance was fueled by organic growth and institutional repo. Finally, market data growth was driven by investments in our proprietary data products, which are seeing early signs of success. Moving on to slide six, let me provide a brief update of our four main focus areas, global interest rate swaps, US Treasuries, US credit, and global ETFs. Starting with interest rate swaps, which is our largest rate product, an improving macro backdrop relative to last year aided our continued organic growth efforts and led to a record Q1. We continue to attract new clients and deepen our client wallet share by driving higher engagement with both existing and newer products and protocols. This led to overall swap volume growing by 25%. Swaps market share increased to 12.7% as measured by Clarus. Longer term, we remain excited by the multi-year opportunity here as the market continues to electronify. Moving on to US Treasuries, another rate product that continues to perform at record levels with volumes up 30% year-on-year, led by both the institutional and wholesale business and aided by our NFI acquisition. Market share rose to 19.6% of the US Treasury market. The backdrop of healthy issuance continues to support the institutional channel, and the pickup in volatility aided both the wholesale and institutional channels. Our share gains have been driven by existing clients doing more business and making further inroads into the T-bill market. Looking ahead, we continue to invest in driving the adoption of early-stage institutional streaming protocols like Tradeweb Plus. The wholesale NFI integration is going according to plan. We are finalizing our clearing arrangements, submitted our broker-dealer consolidation plan for regulatory approval, and recently announced the timeline for the migration of our data centers. Shifting to credit, this was another record quarter as our business continues to surge ahead, generating more than $86 million in revenues to start the year. Seven years into our journey, it's amazing to see the growth in this business, with high yield hitting a new market share record in January. We are continuing to see growing institutional client demand in our innovations like portfolio trading, AllTrade, and net spotting, and growing wholesale adoption around innovations like session trading and Rematch. Looking ahead, we continue to see a lot of opportunity in that credit as our platform continues to scale and as the retail business recovers. Finally, within equities, institutional ETFs produced record quarterly revenues with average daily volume up 54% year-on-year, driven by new client wins and strong industry volumes. The Q1 continued the strong growth we've seen in global ETF volumes after a record 2020 and 2021. ETFs are increasingly becoming a core tool for our buy-side clients as they use the products for cash equitization, short-term tactical trades, or tax management purposes. We are assisting our clients by providing straight-through processing, integrating pre-trade transparency to reduce the number of clicks involved in dealer selection, and enhancing our list ticket functionality. Fundamentally, we continue to add new clients globally and remain excited about the prospects for the business. Our other initiatives to expand beyond our flagship ETF franchise are also bearing fruit, with momentum continuing in equity options, convertibles, and ADRs. Looking forward, we believe we remain well-positioned to benefit from the continued growth in ETFs globally and as our growth initiatives scale. Finally, as most of you saw in February, I will be retiring as CEO at the end of the year, with Billy taking the reins at the beginning of 2023. I will continue to be involved with Tradeweb's future, having recently been elected as the chairman of the board this past February, effective through the end of 2023. Retiring wasn't an easy decision, but I'm thrilled to be confidently passing the CEO baton to my long-term partner, Billy, at the end of this year. Billy's promotion to CEO is a culmination of over 20 years here at Tradeweb, and he embodies the amazing, innovative culture we have here at the firm. I'll pass it on to Billy to say a few words. Thanks for the kind words, Lee. I am excited by the opportunity to lead this company at a time when the winds of change, electronification, and technological advancements continue to transform the trading ecosystem. I look forward to continuing to work alongside so many creative and talented individuals at Tradeweb and our clients. Lee has been a tremendous leader, creating a culture of innovation and collaboration, and I am focused on preserving that spirit. We have a fundamental view and a core set of beliefs here at Tradeweb that has served us well. With that said, we will continue to be dynamic and listen to our clients and always be open to being moved and influenced. Tradeweb is a company built on breakthroughs, consistent and meaningful solutions created for clients' real-world needs and challenges. The simple truth is our clients dictate the pace of change, and we work alongside them to help drive meaningful innovations to benefit their execution experience. We are laser focused on empowering our, all our clients with innovative technology to access liquidity, accurate pricing, and streamlined workflows. Our strategy is working, and clients have responded to our engagement by pushing our revenues to record highs at Tradeweb. Turning to slide seven for a closer look at credit. We believe this was a very important quarter. For the past few years, we have been very happy with the way in which clients have responded to our vision for electronic credit trading by supporting our brand of innovation. As we reimagined the credit ecosystem by introducing and growing a variety of new protocols, we became the fastest-growing credit platform by both share and absolute revenues. We were especially pleased to see that our belief that our credit platform has reached critical mass play out as liquidity we strived hard to build remained resilient as volatility spiked. We have come a long way since the start of the pandemic. Our brand and competitive position continue to get stronger every quarter. We know we have more work to do and remain focused on helping our clients and capturing the substantial opportunity in global credit we believe is in front of us. A key part of our strategy has been to serve the entire credit market with a variety of protocols. Our share and revenue continues to be anchored by our fast-growing institutional business across both IG and high yield. At the same time, we also believe we have a great balance with wholesale also contributing meaningfully and retail starting to show early signs of a recovery. Additionally, our focus on voice workflow and net spotting also proved to be another differentiator as Electronically Processed shares hit record levels as volatility increased. Our institutional growth continues to be underpinned by growth in portfolio and RFQ trading. The latter remains an area of focus, and we are pleased to see the growth continue to unfold, especially in high-yield RFQs, as client engagement increases. Portfolio trading remains an important protocol, weathering the rapid spread widening and volatility we saw in the quarter. Specifically, we saw a record 45,000 line items trade in March, with record high-yield portfolio trading average daily volume. The value of portfolio trading also continues to resonate globally. Tradeweb facilitated a record $89 billion in portfolio trades in the Q1 of 2022, an increase of more than 25% year-over-year, aided by a client growth of 70%. Behaviorally, clients continue to become savvier in the U.S. in their usage of portfolio trading by putting more dealers in competition, and dealers are becoming more and more sophisticated in the way they price portfolio trades across all environments. Dealers have also become engaged in portfolio trading more than ever with our in-comp portfolio trading, reaching record levels comprising 87% of portfolio trading volumes, up from 64% in the Q1 of last year. The strength in portfolio trading was matched by the rapid growth of our anonymous liquidity solution, AllTrade, which saw a record of nearly $102 billion in volume, an increase of 23% year-over-year. Session trading hit rates held up as volatility increased, and we remain laser-focused on maximizing the value of session liquidity uploaded on our platform through newer protocols like Rematch, which accesses our all-to-all liquidity. Turning to the rest of our credit business, we achieved record revenues in institutional European credit, with strong growth driven by portfolio and RFQ trading. Institutional muni revenues continue to grow rapidly, increasing nearly 50% year-over-year as we continue to gain share and add clients. We recently launched Ai-Price for munis, which leverages our transactional and MSRB data to initially calculate nearly 900,000 end-of-day prices and eventually provide our clients with intraday pricing as well. Our entire muni platform sees one in every six trades that occurs in the muni market today, giving us a great foundation for growth. Our CDS revenues also saw double-digit year-over-year growth across regions. In sum, it was a good quarter for credit, and we continue to believe we have a lot of potential for growth as we look ahead. Moving on to swaps, our biggest revenue bucket within our rates franchise. Just like credit, the multiyear growth story continues as swaps registered another strong quarter, aided by rebounding industry volumes and market share gains. Specifically, the pickup in volatility and rising rate expectations drove a 16% year-over-year increase in Q1 2022 industry volumes. Our variable swaps revenue grew by 19% year-over-year, driven by increased trading and higher fee per million protocols. Market share increased to 12.7% despite a substantial pickup in short-dated central bank meeting date trades in the voice market. These trades tend to be speculative in nature, carrying a low fee per million, and have notionals that could be 10 times larger than our regular swap trades. Our momentum in major currencies continues with record Q1 share in euro and pound-denominated swaps. We believe the LIBOR transition is progressing well. Over 45% of our Q1 volume came from SOFR trades, up from 15% in the year ago period, with 89% of our dollar swap clients having executed a SOFR-based trade since the start of the year. Beyond the risk-free rate transition, we continue to respond to structural changes in the swaps market, making strong but early advances in cleared EM swaps, inflation swaps, RFM protocol adoption, and multi-asset trading. During the Q1, we saw a record EM share and revenues increased by over 200% year-over-year. We also saw a record RFM activity as we continue to onboard dealers and deepen our liquidity pool. Looking ahead, we believe the long-term swaps revenue growth potential is meaningful. With the market still only 30% electronified, we believe there remains a lot that we can do to help digitize our clients' manual workflows while the global fixed income markets and broader swap market grow. Finally, we continue to invest in our leading multi-asset class automated trading capability, AiEX. The Q1 is a testament to growing adoption as clients get increasingly comfortable with low to no touch trading, even with the heightened volatility. The number of AiEX trades grew by 15% year-over-year in the Q1, while the average daily volume increased 31%. In fact, the average daily trades increased each month in the Q1 despite the pickup in volatility. Clients continue to take advantage of various tools and features like time release and smarter counterparty selection to minimize or eliminate the number of clicks. Time release allows orders to be routed for execution at specific time intervals. We also continue to invest in enriching our advanced dealer selection functionality, which allows clients to customize their counterparty selection according to real-time market conditions and their specific execution objectives. We believe this is really resonating with clients. As clients become more comfortable with automation, we are seeing them get more comfortable trading larger volumes through AiEX. With that, let me turn it over to Sara to discuss our financials in more detail. Thanks, Billy, and good morning. As I go through the numbers, all comparisons will be to the prior year period unless otherwise noted. Let me begin with an overview of our volumes on slide nine. We reported record quarterly average daily volume in excess of 1.1 trillion, up 11% year-over-year and up 8% when excluding short tenor swaps. Among the 22 product categories that we include in our monthly activity report, 12 hit quarterly records, while another four achieved their second-highest quarterly ADV. Perhaps even more notable, 11 of the 22 product areas produced year-over-year volume growth of more than 20%. Areas of strong growth include US and European government bonds, global swaps, U.S. corporate credit, U.S. and European ETFs and institutional repo. Slide 10 provides a summary of our quarterly earnings performance. The record Q1 volumes translated into gross revenues increasing by 13.9% on a reported basis and 15.9% on a constant currency basis. We derived approximately 39% of our revenues from international customers and recall that approximately 30% of our revenue base is denominated in currencies other than dollars, predominantly in euros. Our variable revenues increased by 18.9%, and our total trading revenue increased by 14.5%. Total fixed revenues related to our four major asset classes continued to grow, up 5.4% and 7.9% on a constant currency basis. Rates fixed revenue growth was primarily driven by the addition of the NFI acquisition, while credit fixed revenue growth was driven by European credit. Other trading revenues were down 16%. As a reminder, this line does fluctuate as it is affected by periodic revenues tied to technology enhancements performed for our retail clients. Market data increased by 7%, primarily due to growth in proprietary data products. Adjusted EBITDA margin of 51.6 declined by 40 basis points relative to the Q1 of 2021, but increased 75 basis points from the full year 2021. Relative to 1Q 2021, margin was impacted by higher compensation due to three factors. One, increased headcount, two, a pickup in incentive compensation to better align with stronger revenue performance, and three, elevated payroll taxes driven by the annual vesting of equity compensation at higher stock price levels. With that said, we remain committed and on track to delivering annual margin expansion in 2022, and there has been no change to our philosophy of balancing revenue growth with margin expansion. All in, we reported adjusted net income per diluted share of $0.48. Moving on to fees per million on slide 11. The trends that I'm about to describe are driven by a mix of the various products within our four asset classes. In sum, our blended fees per million increased 6% year-over-year, primarily as a result of stronger growth in higher fee per million credit, cash rates, and cash equities. Excluding lower fee per million short tenor swaps and futures, our blended fees per million were up 9%. Let's review the underlying trends by asset class, starting with rates. Average fees per million for rates were up 1%. For cash rates products, fees per million were up 8%, primarily due to growth in higher fee per million US Treasuries and migration of certain European government bond clients from fixed to variable contracts. For long tenor swaps, fees per million were up 2%, primarily due to growth in billable volume, EM swaps, and RFM. That was offset by lower duration. In other rates derivatives, which include rates futures and short tenor swaps, average fees per million decreased 17% due to a shift towards OIS, which carries a lower fee per million than FRAs. Continuing to credit, average fees per million for credit decreased 6% due to relative product mix, with stronger volume growth in lower fee per million credit derivatives and Electronically Processed trades. Drilling down on cash credit, average fees per million increased 9% due to stronger growth in U.S. high yield, which carries a higher fee per million than overall cash credit. Our U.S. high grade and high yield volumes were a record in the Q1. Looking at the credit derivatives and electronically processed U.S. cash credit category, fees per million increased 9%, driven by growth in European CDS, which carries a higher fee per million than the group average. Continuing with equities, average fees per million for equities were up 13%. For cash equities, average fees per million increased by 11% due to an increase in fees per million within U.S. ETFs, which was driven by a decrease in notional per share traded. Recall in the U.S., we charge per share and not for notional value traded. Equity derivatives average fees per million decreased 4% due to growth in equity futures, which carry a lower fee per million than the equity derivatives average. Finally, within money markets, fees per million increased 1%. This was primarily driven by an increase in our European repo fees per million, which was partially offset by a reduction in our retail CD fee per million. The higher fee per million retail money markets business remained pressured by the low interest rate environment. Slide 12 details our expenses. Adjusted expenses for the Q1 increased 14.6% and 17.1% on a constant currency basis. Recall approximately 15% of our expense base is denominated in currencies other than dollars, predominantly in sterling. Q1 2022 adjusted operating expenses were higher as compared to the Q1 of 2021 due to increased employee compensation, technology and communication, G&A, and D&A, which were partially offset by lower occupancy costs. Compensation costs increased 17.4% due to higher headcount, incentive compensation, and payroll taxes related to equity compensation that I discussed earlier. Adjusted non-comp expense increased 8.7% on a reported basis, primarily due to technology and communications and D&A, but were helped by favorable movements in FX. Adjusted non-comp expense on a constant currency basis increased 15.2%. Specifically, tech and communication costs increased primarily due to higher clearing and data fees as a result of higher credit AllTrade volumes and streaming US Treasury volumes, which continue to grow. In addition, this quarter also saw the continued impact of our previously communicated investments in data strategy and infrastructure. Adjusted general and administrative costs increased primarily due to an increase in travel and entertainment as we recover from the pandemic. Favorable movements in FX resulted in a $1.1 million realized gain in the Q1 of 2022 versus a $1.5 million realized loss in the Q1 of 2021. Professional fees decreased 1.2% due to lower legal costs, partially offset by the inclusion of NFI expenses following our acquisition in June of last year. Slide 13 details capital management and our guidance. First, on our cash position and capital return policy. We ended the Q1 in a strong position, holding $828 million in cash and cash equivalents, and free cash flow reached nearly $511 million for the trailing twelve months. We have access to a $500 million revolver that remains undrawn as of quarter end. CapEx and capitalized software development for the quarter was $18 million, an increase of 43% year-over-year, primarily due to accelerated timing of investment spend. We continue to expect capital expenditures and capitalized software to be in the range of $62 million-$68 million for the full year. With this quarter's earnings, the board declared a quarterly dividend of $0.08 per Class A and Class B share. We spent $143 million offsetting equity dilution during the quarter. Specifically, we spent $47 million under our regular share buyback program, leaving $27 million for future deployment at the end of the quarter. In addition, we withheld $96 million in shares to cover payroll tax obligations related to equity compensation. As a reminder, we plan to use our share repurchase authorization to mostly offset dilution from ongoing equity compensation. Turning to other guidance items for 2022. In line with our previous guidance, we expect adjusted expenses to range from $620 million - $655 million. For forecasting purposes, we continue to use an assumed non-GAAP tax rate of 22% for the year. Finally, on slide 14, we've updated our quarterly share count sensitivity for the Q2 of 2022 to help you calibrate your models for fluctuations in our share price. Now I'll turn it back to Lee for concluding remarks. Thanks, Sara. 2022 is off to a strong start, and I'm very encouraged by the broadening momentum across our business, giving us a strong foundation for future growth. With a couple of important month-end trading days left in April, which tend to be our strongest revenue days, momentum from the Q1 has continued with overall revenues and volumes up double digits relative to April 2021. Similar to the Q1, the diversity of our growth remains a theme as we continue to see double-digit average daily revenue growth across global interest rate swaps, European government bonds, global equities, and U.S. And European corporate credit. Our IG share has rebounded strongly from March to exceed Q1 levels, while high-yield share is trending similar to the Q1 levels. I'd like to conclude my remarks by thanking our clients for their business and partnership in the quarter, and I want to thank my colleagues for the efforts that contributed to the record quarterly revenues and volumes of Tradeweb. With that, I'll turn it back to Ashley for your questions. Thanks, Lee. As a reminder, please limit yourself to one question only. Feel free to hop back in the queue and ask additional questions at the end. Q&A will end at 10:30 A.M. Eastern Time. Operator, you can now take our first question. Thank you. If you'd like to ask a question, that is star one. Again, if you'd like to ask a question, that is star one. Our first question comes from Rich Repetto from Piper Sandler. Your line is now open. Yeah. Good morning, Lee and Billy and Sara. So I guess first a Q&A question on volatility. You know, the current environment for rates has been friendly and while you know at least in 2021 the environment for credit has been less friendly, but it seems like it's improving here in 2021. Lee, as you think about the rates business and you look back at you know prior periods and if you compare the tailwinds, like especially in 2018 and 2021, when you had you know high double digits, 17%, 18% revenue growth. How would you compare the tailwinds now to those years? I guess on Billy, you know, you made a lot of comments about, you know, how things have improved, but could you get more specific on what really comes to mind from you that highlights the performance, you know, with higher volatility on the credit side? Hey, Rich. It's Lee. Thanks for the question. I'll take the rates part of the question and then have Billy handle the credit piece. I think. Look, it's always tough to draw comparisons with different market conditions. I think this is true across, you know, all asset classes. You know, 2018 was one set of circumstances. We had MiFID phasing in, MiFID II phasing in in Europe with swap business. 2020 and 2021 obviously were impacted by the pandemic and increased electronification. When we look at, just talking about the Q1 for this year, in our rates business, this was a very strong quarter for us. You know, over 14% growth, when we compare it to the Q1 of last year, which is great. There's a number of unique things obviously happening in the market right now with, obviously what's happening with the Fed, interest rates in general. We have the war in the Ukraine with Russia. I mean, this created quite a bit of uncertainty. I think also in terms of, what's gonna happen in the with respect to yields is sometimes we'll pause things a little bit, because of the uncertainty. But generally, this has been a favorable environment. You know, as we've kind of suggested, as we've seen in April, you know, we continue to sort of have this kind of growth. I mean, the best thing I think is to look at, you know, go back historically, look at things. Every period is unique, but if you look at what our growth has been over a variety of cycles, you know, from 2016 to 2020, it's kind of been that 11.5% compound annual growth rate, which is indicative, but it's not, you know, it's not certain. I think. We're pretty positive about things going forward in the rate space. You know, we're off to a very good start. I think that there will continue to be, if I were to speculate, volatility that will be, you know, a positive for our volumes on our business as we kind of go forward. Let me pass it over. Yeah. to Billy to say a few things. Sure. Hey, Rich. Making me get specific, which we'll hold against you at some point. You know, in 2021, you know, Rich, as you know really well, that was our year. That was a really big year in credit, right? We went from 7% market share in IG to 12%, 2.5% in high yield to 5.5%. Like, made these huge strides, right? Getting to this place that we call critical mass, which is like a big expression and a really important expression. As you know, we kind of did it two ways. Super talented, very important, experienced team, that kind of starts there. Then the second thing is I've talked about this a lot, this sort of market has this appetite to support competition. Those things were working for us, right? Around March of 2020, if you remember, we really made, I think, in a significant way, this commitment towards our liquidity pool, right? Getting it deeper and more vital. The numbers, you know, specifically are kind of, you know, the number of our all-to-all responders in our liquidity pool doubled. The number of our portfolio traders since March of 2020 is up 150%, Rich. One thing that's really important, we talk about AiEX a lot. It's like a very sticky indicator of how we're doing with our clients. It's up four times since March of 2020. So now, you know, 40% of our RFQ users in credit now trade with us through AiEX. That's like a big, important kind of number and stat. A little bit of your question, I think, which is important, is kind of like, you know, 2021 was one market. What would happen to our innovations? What would happen to kind of you know, you've heard us use this sort of expression around the light bulb. What would happen around that, you know, when the market got tough, when the market got volatile, when prices were going all over the place, would it hold up? You know, I think it's a really important question, and it was a really important test for us. You know, the answer is, I think it's really, really important for you to hear me say this. In March, when things got tough, you know, as you know, our portfolio trading in high yield was a record, 6.1%. I mentioned on my prepared remarks, we had 45,000-plus line items in one of our portfolio trades. That's a record. You know, 30% of our RFQ traders, Rich, in March 2022 did portfolio trades with us. That's up from 15% two years ago and 5% from last year. These underlying numbers are building up. When we kind of step back, we say we went through a test in March, and I think we passed that test. At the end of the day, as you know really well, the credit market is getting more and more sophisticated, and our goal is to keep up with that sophistication, keep building these products the right way for our clients and keep doing as well as we are doing. We feel really good about where we are. Thanks for the question. Got it. Thanks. A specific answer, Billy and Lee. Thanks. Mm-hmm. Thank you. Our next question comes from Gautam Sawant from Credit Suisse. Your line is now open. Good morning, Lee, Billy, and Sara. Thank you for taking my question. Sara, can you please frame the opportunity for Tradeweb to drive operating leverage in 2022, as well as expense growth in the context of investing in new organic growth initiatives versus other cost pressures? Sure. Thanks for the question, Gautam. Look, we're always thinking about the balance between investing for growth and margin expansion. In fact, as you know, as senior leaders of the firm, we're all incentivized to think about balancing those equally in our compensation structure. We continue to believe we can drive operating margin expansion in 2022, you know, when we compare it to the full year last year margin of 50.8%, and we can do that at either end of the guidance range. I wouldn't get bogged down, you know, in the Q1 comparison. It was particularly impacted by a number of factors which I highlighted in my prepared remarks. You know, in particular, the performance-driven comp and payroll taxes that are always outside in the Q1 were particularly outsized this year, given the strong performance we had last year and our stock price, which was $100 when the PRSU vested. As you think about our ability, you know, one other thing to think about with margins is FX this year. You saw that negatively impact our results this quarter, and we have a lot of disclosure around that in our Form 10-K. As far as your specific expense growth question ultimately comes down to revenue growth, which is our priority and which we've gotten right so far, and we believe margins take care of themselves as our products scale with that. At our current revenue growth levels, which you can see, we've been able to invest in organic growth that you were asking about, absorb the cost pressures and still grow margins. Got it. Thank you. Thanks for the question. Thank you. Our next question comes from Michael Cyprys from Morgan Stanley. Your line is now open. Hey, good morning. Just a question for Billy. I was hoping you could talk about the CEO transition, how things might be different under your leadership, Billy. Then as you think about future growth, how do you see the competitive environment evolving in credit? Sure. Hey, Michael, how are you? Yeah, thanks for the question. I'll answer the sort of part of it, the first part of it, just super authentically and genuinely, I think, in a way that Lee will really respect. You know, we're all kind of humans here, right? There's sort of complex emotions involved. On the one hand, to make an obvious point, I'm super enthusiastic, excited, and ready for all of this. On the other hand, Lee and I have enjoyed a very unique and important partnership for a really long time. You know, that's changing. The good news is I'm still gonna have Lee as a very important advisor as the chair of the board, and that feels really good. We're working, you know, super diligently around transition in all the ways that you would expect. We have a very talented team here. We feel really good about the direction of the company. The nice part about our partnership at the end of the day is we've been kinda shoulder to shoulder around the strategy of the company for a very, very long time. I couldn't feel better about where we're headed strategically speaking. I'm not gonna kinda advocate for any kinda change at all around that. We feel super good about where we're headed. I'm excited about it. I've had, you know, great support starting with Lee, obviously, you know, the board and then David at LSEG. It's been across the board, a really good feeling. By the way, as we're working and going through all of the transition stuff, we are, you know, super busy with our day jobs. There's many days where we roll up our sleeves, get to work and keep moving things forward in the way that you would expect. It's an exciting, fun, and interesting, you know, time for us. The competitive landscape is gonna keep kinda getting more competitive, and we welcome that. We understand that. Lee's always said this, we've competed, you know, as a company against Bloomberg from day one, and we're comfortable competing. There was a time, specifically to your question, Michael, around credit, where the question was, with the strong player in the market, is there room for two? That was the question about how we would penetrate and do well in credit. The obvious answer is, there's more than room for two. There's now a third player in the marketplace. Things are competitive. We continue to do really well, build innovations, connect with clients, and move the ball forward. We love the atmosphere that we're in, and we're gonna continue to work hard and do really well. Thank you for your question. Great. Thanks so much. Appreciate it. Yeah. Thank you. Our next question comes from Craig Siegenthaler from Bank of America. Your line is now open. Hey, good morning, everyone. My question is on the contract renegotiation with Refinitiv. Based on pricing trends at your competitors, it's looking like there could be a nice increase in revenue. I wanted to see if you could share your perspective on this potential catalyst. You know, I think just broadly speaking, in terms of our information services, there's a lot of demand for our data, and we are really excited about the long-term opportunity. You know, it's worth pointing out that data, first and foremost, we think about how it drives trading on our platform, and that's our core focus. We have a great partnership with Refinitiv, and that contract is a long-term contract, and we'll have that discussion. The partnership there and the opportunity to work together is, has been quite favorable. Away from that contract, we do have proprietary data products that we're investing in and realizing some strong growth in as well. Overall, we're quite pleased about where we are. Thank you, Sara. Thanks. Thank you. Our next question comes from Dan Fannon from Jefferies. Your line is now open. Thanks. Good morning. I wanted to follow up on the retail opportunity. In the prepared remarks, you guys mentioned a couple times about retail showing some signs of life and improving. Maybe give us a sense of what the contribution is today, maybe what it's been at points in time before historically. I think it does carry a higher capture rate and higher fees. Just wanna put some numbers around what that opportunity is like. Sure. This is Sara. Thanks for that question. In the Q1, the retail sector accounted for about 6% of our revenues, and it was up about 7% year-over-year. Just, you know, it's a great time to talk about retail because the sector, we are seeing, it come back. For context, if you think about its contribution last year, it was about 7% of firm-wide revenues. If you go back a little bit further, pre-pandemic in 2019, that figure was about 10%. It puts it in context. Obviously, the environment we've seen over the last few years, particularly with low rates and depressed yields, it's been a little bit less attractive to financial advisors. As I mentioned, we're seeing signs of that recovery, albeit gradual, I think, in how it realizes in our revenues. Maybe I'll just highlight two points specifically, and Billy, let me know if I missed anything. You know, if you think about what's underlying our retail revenues, retail muni revenues in the Q1 were up 15%, albeit down double digits from the Q1 of 2019. You kind of get that context. We're really, you know, quite pleased with our middle market muni business, which has done much better. Revenues there hit a new record, up nearly 50% year-over-year in the Q1. Our efforts to penetrate and really electronify that tax-exempt institutional space are paying off. Looking ahead, we do think, you know, the pickup is there. It just will be gradual, you know, as rates rise and the bond ladders reprice. I think you asked about fees per million. As a reminder, retail products tend to have higher pricing than our cash credit average. To the extent these businesses pick up, we'd expect that to be accretive to our fees per million. Yeah. The only thing I would add is I mentioned to Rich's question and the first question about just the importance of the liquidity pool and credit. One of the things that really gave us an edge in terms of building out that liquidity pool was getting into the retail business the way that we did. It allowed us to onboard a lot of these kind of essential responders in the all-to-all network. There's an important strategy that we're getting out of being in that business as well. Great. Thank you. Thank you. Our next question comes from Alex Kramm from UBS. Your line is now open. Yeah. Hey, good morning, everyone. Wanted to come back to credit for a second. One of the things I'm, I guess, sensing is more appetite from the, you know, large buy side firms, but even maybe some of the middle tier buy side firms to also do more direct connectivity with, you know, the larger dealers, who are also increasingly aggregating flows from other places. So just wondering if you're actually seeing that, if that's a competitive dynamic that we should be watching. Yeah, what this could mean for Tradeweb in the future. Are you competing more with, I guess, like, dealer-sponsored internal platforms? Thanks. Yeah. It's a good question. It's out there, and we've been hearing about it too. And it's definitely something that you can tell a couple of the bigger buy side firms have as an agenda. It's not something that we're worried about. We do feel really strongly about how we built our protocols, and the collective network that we have, and that our competitive position is really strong there. It's out there. We keep our eye on kinda everything around the competitive space, but we feel really strongly that if we keep delivering to our clients the right way around all of these things, the network effect of it all will win out at the end of the day. It's not something that's like sort of big time on our radar around something like that, but it's something that we are definitely aware of. Excellent, helpful. Thank you. Yep. Thank you. Our next question comes from Alex Blostein from Goldman Sachs. Your line is now open. Hey, everybody. Good morning. Another one around credit, definitely feels like it dominates most of you guys' calls. I wanna take a quick step back for a second, and I know you guys provided a lot of color around portfolio trading and the fact that it still remained quite active despite increased volatility, but also coupling that with comments, Billy, you made around the appetite from clients to do more continues to increase and sort of the adoption curve continues to come up. I think in the past, we talked about this being sort of a mid-single digit percentage of overall credit volumes. Based on the kinda client conversations you have today, where do you think that could ultimately go? Do you think that PT is still gonna be sorta one of the key drivers behind Tradeweb's market share gains or the products that has expanded enough where you're gonna be more competitive in other things? Well, yeah, we do. We do think it's gonna be super important. I think, like, sort of producing at that number, what did you say, like mid, you know, 6% or whatever, in that kind of a volatile market in March is a pretty strong testament and a pretty strong statement. We would never characterize it as like a flat lining around the appetite for portfolio trading. It's continuing to build up. The reason why it's gonna continue to build up is because it solves for some major things from the buy side's perspective, right, Alex. Executable pricing, that's a big deal to the buy side. I mentioned the fact that the market's getting more sophisticated. The dealer's ability to respond now to portfolio trades, specifically, you know, in very volatile situations, is growing and getting way more on the screws. These are all, like, big time important things. We feel really strongly that portfolio trading is, you know, only gonna become a bigger and more important piece of the buy side's workflow. You know, other protocols obviously will matter, too. It's always getting all of the pieces of the puzzle together and credit the right way. The all-to-all network, as I mentioned, is table stakes. That's really important. Everything that we're doing, Alex, around Sweep, we feel very, very strongly about. It's getting these kind of pieces of the puzzle together in the right way matters a ton. We really feel like portfolio trading got stressed in March and absolutely came through on the other side as a more important protocol than ever. Cool. Thanks very much. Yeah. Thank you. Our next question comes from Ken Worthington from JP Morgan. Your line is now open. Hi, good morning, and thank you for taking the question. You mentioned in the prepared remarks that some European clients converted from fixed to floating contracts. Given that at least we think, you know, volumes have been rising, I assume that conversion was probably driven by Tradeweb as opposed to the other way around. If that's correct, is there an opportunity to convert more customers to these variable contracts over time? Maybe what is enabling this conversion now? Is it sort of macro or micro specific? Is the conversion more likely over time in credits or rates? You know, it's a hard question to answer with a lot of precision. The reality is the decision to change between fixed and variable fee contracts is a combination of different reasons, and a lot of it's idiosyncratic in terms of what's going on with clients, the market, the various different products. It's really hard to extrapolate that and see a broad trend. You know, it really just depends on the particular situation. We did have some of that change in European govies over the last quarter. It's probably a bit of a combination of both coming from us and the dealers. I wouldn't get too caught up in terms of looking at it as something that we're driving, you know, in the absence of communication with our clients. Should we expect more over time? I wouldn't think of it as like an outlying driver of anything. Okay. Great. You answered it so much. Yeah. I think just generally speaking, I think the way if you're trying to model it, I would think about fixed trading revenue in that sort of low single digit growth rate. There's gonna be different, you know, pops you'll see in variable, but that line is probably in that ballpark. Okay, great. Thank you. You're welcome. Thanks for the question. Thank you. Our next question comes from Kyle Voigt from KBW. Your line is now open. Hi, good morning. Maybe just a question on the cash treasury business. One of your newer competitors in the space spoke a bit recently about bolstering their all-to-all trading Treasuries and also cited strong needs for such a solution. Just wondering if you could talk a bit about whether you're hearing similar type of client requests for pure all-to-all trading functionality in cash Treasuries market. Do you think this protocol could be as successful in treasury that it has been in corporates, for both you and others? Thanks. Broke up a little bit, Kyle, but I think we got the gist of your question. You know, a couple of very strong points. One is obviously the treasury market and the liquidity around the treasury market is obviously very different than the credit market. We feel really strongly, particularly around how we've, you know, we've gotten AiEX into all of our clients and how clients have gotten much more sophisticated in terms of their search for liquidity, that the traditional model is really working in Treasuries. That being said, in an obvious way, we don't discount change at all here, right? We are actively watching that marketplace, particularly as it pertains to the off-the-run market. We feel we have all of the pieces together ready to go if we feel like it's the right time to move in that direction. If we do feel like that, we will move there strongly. We do not feel like the timing is now, and we feel very strongly about where our offering is right now as we speak, and we're in a really good position. Eyes on the competitive landscape always, but a very strong understanding that the treasury market operates differently than credit, and we feel like we're in a really good position with our clients there. Understood. Thank you. Yeah. Thank you. Our next question comes from Brian Bedell from Deutsche Bank. Your line is now open. Great, great. Thanks very much. Good morning, folks. Maybe, Billy, sorry to come back to the credit market here, but maybe if I can just sort of have a more of an overarching comment on the future of competition in this market. Obviously, you said that we've got a third competitor that's a little bit more entrenched. Obviously, the tailwind is very good here in corporate bonds in both high grade and high yield in terms of electronification. There's certainly room for multiple competitors. As you see this, the competition developing in this over the next, you know, couple years or so, do you think it's gonna be more a battlefield of, protocol development, you know, coming out with new and more innovative protocols or rather, you know, growing the sales, force or leveraging the network effect? Then maybe if you can comment on whether you think price competition will enter the market. Yeah. It's a really well-framed question. It is kinda all of the above, right? We do make a really strong point that, you know, even though we are extremely comfortable and confident with where we are with our pricing model, we have never led with price because we just don't think that that's the right kind of technique in terms of migrating, you know, the competitive landscape in the way that we have. We've always led with innovation, problem-solving and saving time and money for our clients first and foremost. We think that will continue to win out in the end. You know, the credit market has obviously experienced like a tremendous amount of innovations over the past bunch of years. Part of those innovations have come because there's been a lot of competition in the space. It's pretty interesting, right? The net winners around all of this has really been the community of users. When you think about what's happened with the all-to-all network, net spotting and net hedging, portfolio trading, session trading, these are like pretty amazing protocol innovations that have happened, you know, recently. A lot of that's become because we've all gotten better, you know. You know, between the three of us, I think we've all raised our game, gotten better, gotten more in tune with our clients, delivered and developed, you know, strong technology. It's all been kinda working. We feel really strongly that it's kind of a mixture or combination of what you described, and we'll continue with that playbook because it's been working for us. Great. That's great. Thank you. Thank you. Our next question comes from Rich Repetto from Piper Sandler. Your line is now open. I apologize, that line disconnected. Our next question is from Craig Siegenthaler from Bank of America. Your line is now open. Hi, everyone. This is Eli from Craig's team with a follow-up. We wanted your insight into the consolidated tape pilots for fixed income, which are being rolled out in Europe this quarter. There is some media attention around a potential consortium between Tradeweb, MarketAxess, and Bloomberg for a joint tape project. Can you share your thoughts on that development too? Thanks. Hey, Eli. It's Lee. Thank you for the question. I'll play the bad guy here at the end of the call. We're not gonna comment on that one. It's just not something we wanna discuss at this stage. Thanks for the question. No worries. Thanks. Mm-hmm. Thank you. I am showing no further questions. I would now like to turn the call back over to Lee Olesky for closing remarks. Okay. Thank you, everyone for joining us this morning. We're really pleased that we had a record start to 2022. Obviously, if you have any follow-up questions, feel free to reach out to Ashley and the team, and have a great day. Thanks again. Bye-bye. Thanks, guys. Thanks. This concludes today's conference call. Thank you for participating. You may now disconnect.
