Thanks, Ashley. Good morning, everyone, and thank you for joining our third quarter earnings call. We delivered another strong quarter, surpassing $500 million in quarterly revenues for the third consecutive quarter. Year-to-date revenues as of the third quarter are up 21% or 17% organically, putting us on track for another year of double-digit revenue growth. We believe change is constant. The current macro environment is defined by historically low interest rate volatility, tight credit spreads and muted equity volatility. At the same time, geopolitical uncertainty and the rapid rise of artificial intelligence continue to reshape how we work and live. We've consistently thrived amid change, and we believe we're well positioned to keep doing so. From the emergence of decentralized finance to shifting regulatory frameworks, we believe our global fixed income platform and network put us in the catbird seat, helping our clients solve their real-world intangible challenges. While the pendulum may be swinging away from globalization, fixed income and ETF markets are becoming increasingly interconnected. Clients and major dealers are thinking globally and nonbank liquidity providers are expanding their global presence, bringing new technology and data capabilities to the ecosystem. As clients seek more time and cost-efficient ways to interact across markets, we remain focused on delivering innovative collaborative solutions that enhance liquidity and efficiency across the global fixed income ecosystem. Diving into the third quarter, despite muted volatility, strong client activity drove 13% year-over-year revenue growth on a reported basis. We produced strong third quarter revenue growth despite facing increasingly tougher year-over-year comparisons, especially in August, which last year defied the typical seasonal slowdown and was exceptionally active as macro growth fears grip the market and the yen carry trade collapsed. Our international revenues continue to scale higher delivering 25% year-over-year growth as our strategic initiatives in EM and APAC continue to pay off. We continue to balance investing for growth and profitability as adjusted EBITDA margins expanded by 54 basis points relative to the third quarter of 2024. Turning to Slide 5. Rates produced its second highest revenue quarter driven by continued organic growth across swaps and global government bonds, while mortgages produced record revenues. Credit growth was led by strength across munis, European credit and emerging market credit. Money markets revenue growth was led by the addition of ICD and aided by record quarterly revenues across global repos. ICD continues to build back balances post the April volatility that led to some large clients drawing down their money market fund balances to tactically buy back shares in the market and increase spending ahead of potential tariffs. ICD revenues were up 7% relative to the second quarter of 2025. Equities posted another strong growth quarter with revenues up 17% year-over-year, led by growth in global ETFs and equity derivatives. Other revenues grew over 50% as we see growing contributions from our emerging digital asset initiatives. Finally, market data revenues were driven by growth in our proprietary data products. We have reached an agreement in principle to renew the LSEG market data agreement, which is up for renewal at the end of October, for an additional 3 years striking the right balance between maintaining the integrity of our platform and commercializing our rich data sets. We expect this agreement will not only generate significant more revenue for Tradeweb, which Sara will touch on later, but it also maintains flexibility to grow our proprietary data business. We also see additional upside as we build more products to enhance the trading experience of our clients. Turning to Slide 6. This quarter saw a significant drop in intraday volatility from the off-the-chart levels seen in prior periods, specifically it was down 19% year-over-year and 30% quarter-over-quarter. All in, U.S. treasury revenues decreased slightly by 2% year-over-year as positive revenue growth across our institutional channel was more than offset by weaker wholesale trends, a business that tends to thrive when there is heightened volatility. One of the trends that has attracted a lot of attention this year is the rise of voice activity in tandem with, and not at the expense of, electronic trading. Year-to-date, electronic industry average daily volume saw a 10% increase year-over-year. We also saw a 26% increase in industry voice average daily volume. This distinction is very important. Electronic trading remains robust and should continue to rise, but we are operating with a continued paradigm of extreme market conditions, this time marked by unusually low volatility. This is driving more complex voice-centric package trades in the market, a mix shift that weighed on our U.S. treasury market share, which stood at 22% in the third quarter. However, our share is rebounding. It increased quarter-over-quarter with September reaching the highest levels since March of this year. In addition, this week, we did our first package trade with a bespoke swap versus the U.S. Treasury. This is an entry point into a world of more complex package trades across the deep liquidity we have in U.S. treasuries and swaps. Our competitive position remains strong on a relative basis, we exceeded 50% for the sixth consecutive quarter in institutional U.S. treasuries versus our main electronic competitor. During the quarter, we expanded our dealer algorithmic execution capabilities. We expect additional global dealer algos to be onboarded in the coming months, further enhancing our unified multi-dealer and multi-asset platform. Finally, attacking voice packaged trades remains a main focus for the team, and we believe we have all the solutions in-house, especially with our r8fin asset. Turning to wholesale U.S. treasuries. Revenues were down 6%, mainly driven by lower volumes across our central limit order book, partially offset by growth across our wholesale streaming protocol. Wholesale continues to be a strategic priority as we focus on expanding our network of liquidity providers and strengthening our liquidity pools in alignment with our multi-protocol platform strategy. In equities, ETFs posted strong double-digit revenue growth as we continue to deepen integration with our clients. A key differentiator with our ETF clients has been our AiEX automation solution with average daily trades increasing over 90% year-over-year. While AiEX is deeply penetrated across European ETFs, we are now seeing strong adoption across U.S. ETFs with AiEX average daily trades up 70% quarter-over-quarter. Our efforts to broaden our equity presence beyond our flagship ETF franchise continued to pay off with institutional equity derivative revenues up 16% year-over-year. Looking ahead, the pipeline remains strong as the benefits of our electronic solutions continue to resonate with our clients. Turning to Slide 7. Global Rates continue to deliver diversified revenue growth across an expanding range of products and geographies. Rates have been a core growth engine for us with year-to-date revenues up 23% year-over-year and averaging 16% annual growth since 2019 with international being a highlight. Even with our scale, the majority of Global Rates products still trade over the phone or chat. That's a significant opportunity. We are leaning into it by building more innovative electronic solutions that make markets more efficient, transparent and connected across swaps, government bonds and mortgages. We are pushing into new voice-centric markets like bilateral and multi-asset package swaps, specified pool trading and mortgages and packaged trading across global government bonds. Altogether, we estimate these initiatives to open up a revenue TAM of nearly $500 million annually. By capturing share from traditional voice trading and continuing to innovate with clients, we continue to strengthen our competitive position in Global Rates. Moving to Slide 8. We have spent years building our strong global interest rate swaps foundation, and it's paying off. Clients continue to shift more of their workflow from voice to electronic and we're right at the center of that change. What started as a regulatory push has evolved into a structural movement. Clients and dealers have never been so invested in building out more efficient workflow options for their voice flow. From 2019 through 2024, swaps revenues have grown at more than 20% on average. And year-to-date, we have accelerated to 40% year-over-year. Just like our broader rate franchise, the growth has been diverse, over 30% year-to-date revenue growth in European and dollar swaps, over 70% across APAC and our emerging market initiatives alone added over 500 basis points to our total swaps year-to-date revenue growth. We are seeing a client base that's deeply engaged, active, cross-currency and increasingly electronic. And while compression can sometimes mask the strength of the business, the underlying trend is clear. We continue to grow our overall risk market share. Even with all of that progress, the majority of swaps trading is still voice-driven, which means there's plenty of room ahead for continued electronification. Our team continues to innovate around that opportunity. We're expanding our presence in emerging market swaps, building multi-asset package swaps capabilities across our clear developed market currencies and making early headway in the bilateral swap space. Each of these initiatives opens new ways for clients to connect, trade and unlock efficiency on Tradeweb. Focusing on the third quarter, global swaps delivered record revenues driven by a combination of strong client engagement, a dynamic macro backdrop, a favorable mix shift towards risk trading and a 7% year-over-year increase in weighted average duration. Altogether, global swaps revenues grew over 30% year-over-year. Core risk market share, which excludes compression trading had a record, rising over 130 basis points year-over-year. Total market share declined from 22.4% in third quarter '24 to 21.2% in third quarter 2025, largely due to a significant reduction in European client-related compression volumes, which carry much lower fee rates. The third quarter highlighted the continued global expansion of our swaps franchise. We achieved record revenues across EM and institutional dollar swaps revenues, while European swaps revenues rose nearly 30% year-over-year. Our strong performance was supported by an 8% year-over-year increase in global active users. We continue to make progress across emerging market swaps and our rapidly growing request for market protocol. Our third quarter EM swaps revenues produced another strong quarter, while our RFM protocol also saw average daily volume more than double year-over-year with adoption picking up. You can see Slide 17 of the earnings presentation for our usual global swaps disclosure. Looking ahead, we continue to believe the long-term growth potential for swaps remains significant with just 30% of the cleared swaps market currently electronified, there is substantial runway to digitize workflows alongside our clients. Our clients have stayed very engaged given the fluid global macroeconomic backdrop, and we continue to partner with them to create better workflow solutions across a growing part of the cleared markets and make inroads into the uncleared swaps market. This month, we launched the first fully electronic swaption package trading protocol in the market, a major step forward in bringing transparency efficiency and 2-way pricing to a product that has historically traded almost entirely by voice. Shifting to Global Credit on Slide 9, low single-digit revenue growth for Global Credit was driven by strong double-digit revenue growth in both European credit and municipal bonds, which more than offset weakness in U.S. credit, where revenues fell year-over-year, mainly due to retail corporate credit revenues that were down nearly 30% year-over-year, primarily reflecting the better relative yields our clients were getting across money markets and munis. Automation continues to resonate with Global Credit AiEX average daily trades, increasing 5% year-over-year. U.S. credit remains a key growth initiative. We are focused on maintaining our leadership position in our pioneering portfolio and session trading protocols and increasing our block market share, perhaps most importantly, continuing to increase our RFQ share which we expect to be the #1 driver of revenue growth in U.S. credit going forward. Our deepening liquidity pool and continuously improving client experience is resonating as we attract more clients and experienced talent across the board. We achieved record block share for the quarter in fully electronic U.S. investment grade at 10%. Our volume growth was driven by continued adoption of our Portfolio Trading, RFQ and sessions protocols. Institutional RFQ average daily volume grew 13% year-over-year with double-digit growth in both IG and high yield. Our efforts to expand into RFQ are seeing continued signs of success with our IG RFQ share of overall TRACE up over 60 basis points year-over-year. Portfolio Trading average daily volume also increased over 10% year-over-year, with over 30% growth across international Portfolio Trading. During the quarter, we saw our largest line item portfolio trade at over 4,000 lines. Additionally, we saw our largest ever international portfolio trade at nearly $1.4 billion. We saw double-digit active user growth across the U.S. and international PT, and we continue to expect adoption of the Portfolio Trading solution to expand. AllTrade had a strong quarter with over $200 billion in volume with average daily volume up almost 10% year-over-year. Our all-to-all average daily volume grew over 35% year-over-year while sessions average daily volume rose by nearly 10% year-over-year. The team remains focused on expanding our network and increasing the number of responders on the AllTrade platform. We saw record responder rates across IG and we also saw strong ETF market maker participation across institutional credit with volume showing strong year-over-year gains. Moving to Slide 10. One aspect of the Tradeweb story that often doesn't get enough attention is how far we've come internationally. Over the past few years, we've built tremendous momentum outside the U.S. with international revenues growing at a 19% compound annual growth rate from 2019 through 2024. And so far this year, they're up more than 30% year-over-year. Today, over half of our overall revenue growth is coming from outside the United States and about 1/5 of that is from regions beyond Europe and the U.K., mainly Asia. Regions that were once viewed as future opportunities have now become meaningful contributors to our business. This success stems from the strength of our global presence and the deep relationships we've built with our international clients. Importantly, these clients aren't just engaging with Tradeweb for international fixed income products, they're increasingly turning to the platform for our home court U.S. products as well, underscoring the global reach and versatility of our offering. Building on the success of our international expansion, we've also seen strong early results from our emerging markets initiative, much like our broader international strategy. We've been leveraging our established developed market presence to drive growth in these regions, and we believe it is working. Traders in emerging markets are deeply engaged with Tradeweb and increasingly drawn to our multi-asset class model trading an average of more than 5 products on our platform. We're now pacing at over $100 million in annual revenue from emerging markets, nearly triple what we achieved in 2023. Yet even with this progress, we're only beginning to tap into a total addressable market exceeding $1.5 billion. Across emerging market swaps in particular, long-standing challenges such as geographic dispersion, pricing opacity and operational inefficiencies have traditionally made voice trading the default. That dynamic is changing. Tradeweb is helping to lead the shift towards electronification by providing clients with more discrete, transparent and efficient execution, innovations like our RFM protocol and AiEX are playing a key role in that evolution. Beyond swaps, we're also seeing encouraging momentum in emerging markets cash credit, where revenues are up more than 40% year-over-year. Last week, we announced the successful launch of the first electronic bond alternative trading system in Saudi Arabia, a foundational moment for a fixed income market structure in the Kingdom and a testament to our growing geographic footprint. The opportunity ahead remains significant, not only within global fixed income and ETF markets, but also as we continue to build brand recognition and expand our footprint across more countries. And with that, let me turn it over to Sara to discuss our financials in more detail.
