Thank you, Ato, and good morning, everyone. Today, I will start with an overview of our fourth quarter and full year 2025 financial and operational performance. I will then discuss our strategic priorities and outlook for 2026 before handing the call to Sarah to walk through the financial results in more detail. 2025 was an excellent year for Nasdaq as we delivered strong organic growth and accelerated innovation across our business. Our team executed exceptionally well, demonstrating the resilience of our platform in a complex operating environment defined by volatile trading dynamics, sustained geopolitical tension, and an ever-changing regulatory landscape. It was also a year of significant milestones for the company. For the first time in our history, we surpassed $5 billion in annual net revenue and $4 billion in solutions revenue. Our index franchise reached new heights, delivering record average AUM, a second consecutive year of record inflows, and the highest number of new index products introduced in our history. Market services delivered record revenues for US equities and US options. We delivered industry-leading new listings performance and a record $1.2 trillion in listing transfers, the strongest year ever for our switch program. In financial technology, we strongly delivered against our cross-sell commitments, deepening our clients' relationships. And we are now proud to call every GSIB a Nasdaq client. Our financial crime management technology business pioneered innovative approaches to fight crime and introduced our new Agentic AI workforce, a suite of Agentic workers that automate key client workflows. We also formed a new partnership with Biocatch to bring additional intelligence and effectiveness to our solutions. These accomplishments reflect not only the breadth of our platform but the momentum behind it as we enter 2026 with more opportunity than ever. For the full year, we delivered net revenues of $5.2 billion, an increase of 12%. Our solutions revenue grew 11% to $4 billion at the top end of the range of our medium-term outlook. ARR ended the year at $3.1 billion, an increase of 10% year over year. Our operating income was $2.9 billion, up 16%, and we delivered 24% diluted EPS growth. Our fourth quarter net revenue was $1.4 billion, up 13% year over year, with solutions revenue of $1.1 billion, up 12% year over year. Expenses in the fourth quarter were $609 million, up 8% year over year. Operating income was $783 million in the quarter, up 16%, and we delivered 27% diluted EPS growth. Our performance was anchored in the strategic pillars of integrate, innovate, and accelerate, which enabled our teams to execute with clarity and focus. Within our integrate priority, we overachieved our expanded efficiency program net expense target with over $160 million in cost reduction actions as of year-end. We ended the year with gross leverage of 2.9 times, outperforming our previous expectation of reaching three times leverage by the end of the year. In recognition of our strengthening balance sheet, both Moody's and S&P upgraded Nasdaq senior unsecured debt ratings in 2025 to Baa1 and BBB+ respectively. Within our innovate priority, we executed across several key initiatives. We embedded AI across our business and have begun rolling out new AI-enabled products with strong client reception. For example, we've seen enthusiastic engagement from Nasdaq Verafin clients for our Agentic AI workforce that we launched at the '3. The first Agentic worker we introduced, our Agentic sanctions analyst, has strong early use among our clients. Continuing the momentum this month, we launched our second worker, the Agentic enhanced due diligence analyst. We look forward to expanding this offering with additional Agentic workers planned for 2026. In market services earlier in 2025, we announced plans to bring 23 by five trading to the Nasdaq stock market. And we will be ready to launch this capability in the '6 subject to regulatory approval. Further, we're driving industry efforts to realize the potential of digital assets across multiple initiatives, including our proposed approach to trade tokenized securities, which prioritizes issuer choice, investor protection, and capital efficiency. Lastly, within our accelerate priority, our one Nasdaq strategy continued to deliver strong results, driving 25 cross-sell wins across financial technology in the year for a total of 42 cross-sells since the Denza acquisition closed. At the end of the fourth quarter, cross-sells accounted for over 15% of Financial Technologies sales pipeline, and we remain on track to surpass $100 million in run rate revenue from cross-sells by 2027. This program culminated in net revenue growth of 12% and solutions growth of 11% at the top of the range of our medium-term outlook. Turning to our strategic and operational highlights for 2025. I'll begin with Capital Access Platforms, where we delivered 10% revenue growth for the year, driven by record index inflows, new IPOs, and strong bookings growth, particularly in data and analytics. Our listings business had the strongest IPO year since 2021. We secured three of the five top IPOs of 2025, including Medline, the largest IPO of the year. It was our seventh straight year as the leading US exchange by proceeds raised, with eligible operating companies raising over $24 billion, including over $10 billion in the fourth quarter alone. In our Nordic markets, we also welcomed the largest IPO in Europe, Verisure. In Europe, we continue to benefit from increased international focus on the Nordics where the equity markets have consistently outperformed the rest of the region. The strength of these markets attracted five new ETP issuers who listed 84 new exchange-traded products across the Nordics in 2025. We also made strong progress on our switch program in 2025, reinforced by Walmart's historic transfer to Nasdaq, the largest exchange switch ever completed. This milestone capped a record year for transfers, including Shopify, Kimberly Clark, and Thomson Reuters. In total, operating company switches in 2025 represented more than $1.2 trillion of market cap, bringing the ten-year total to $3.1 trillion. This quarter, we're introducing an updated listings win rate methodology that better reflects the pathways through which operating companies can list on Nasdaq, including a traditional IPO, a direct listing, and a SPAC combination. Under this new methodology, our win rate was 72% for the full year 2025. This metric also accounts for our newly approved listing qualifications that raise our minimum standards. We've included details on page 21 of our earnings presentation. Looking ahead to 2026, we see signs of accelerating capital markets activity further supported by recent Fed cuts and a very healthy pipeline of late-stage private companies. Based on the current market dynamics, we look forward to an active new issuance year. Our data business delivered robust growth in 2025, as clients across the ecosystem utilized our data more than ever to navigate the financial markets. Our growth was driven by new enterprise license agreements, which increased 24% year over year, and our international expansion efforts, including signing an agreement with one of the largest banks in Saudi Arabia. Our growth was also driven by higher use of our data products across our client base. Our index franchise remains an exceptional growth engine delivering tremendous performance and innovation. We achieved a record $99 billion in net inflows over the last twelve months, including a record $35 billion in the fourth quarter, and exited the year with ETP AUM of $882 billion, an all-time high. In Index, we delivered on our new product strategy, launching 122 new products in 2025, including 60 international products and 32 in the institutional insurance annuity space. Within workflow and insights, our analytics and corporate solutions businesses continue to advance through product innovation and strategic partnerships. In analytics, the investment business delivered robust performance, supported by our strong network effects with platform usage up 10% year over year, driven by increased use of research workflows. We continue to build powerful partnerships, including with Juniper Square and LSEG, reinforcing our strategy to embed Nasdaq's investment data in investment workflows across both public and private markets. In Corporate Solutions, investments in AI-powered features and tools as well as deep client engagement supported new sales efforts in our governance and Nasdaq Lens solutions. These tools also support a retention improvement across the portfolio. Turning next to our financial technology division. In 2025, FinTech delivered strong financial results with 11% revenue growth. Financial Crime Management Technology grew 22% over the year, including 24% growth in the fourth quarter. Regulatory Technology delivered 10% growth for the year, including 12% growth in the fourth quarter. And Capital Markets Technology grew 9% over the year and in the fourth quarter. With more than 3,800 clients, now including all of the GSIBs, the division has established itself as a leading modern technology partner helping institutions address complex risks, critical regulatory reporting, and the modernization of trading infrastructure. In financial crime management technology, we continued strong sales execution during the year, adding 255 new SMB clients and six new enterprise clients, a combined 23% total client growth over the prior year. In enterprise, five of the six new client signings were cross-sells, and we completed three expansion deals with existing enterprise clients for a total of nine enterprise deals. This underscores our ability to deepen client relationships through our one Nasdaq approach. In regulatory technology, our Acxiom SL team broadened our product portfolio to meet evolving regulatory demands, supporting geographic expansion into Saudi Arabia, India, and France. Additionally, we deepened our partnership with Revolut after they consolidated their UK and European regulatory reporting onto our cloud-managed platform this quarter. We also signed a significant cross-sell to a global tier-one bank, an enterprise cloud deployment demonstrating the scale of our solutions and the trust we've established across our platform. In our surveillance business, we drove strong client growth, including an agreement with CFTC, which selected Nasdaq to replace its legacy surveillance system. Overall, in 2025, our surveillance team signed 26 new clients across securities exchanges, crypto trading venues, market participants, and regulators to strengthen their protections across rapidly evolving markets. In capital markets tech, we delivered a strong year driven by durable demand for market modernization solutions. We continue to strengthen our relationships with central banks, ending the year with 24 total central bank clients, including three new central bank clients signed this quarter. Calypso experienced increased adoption from global banks and managers transitioning from legacy on-prem environments to cloud-hosted trading risk and treasury solutions. We're seeing early momentum in Calypso's fully managed service offering on AWS, which drove additional upsells and a major cross-sell into a leading market infrastructure operator during the quarter. In Market Technology, our managed service offering demonstrated strong momentum with growth across multiple solutions. And in the fourth quarter, we signed a major financial market infrastructure client for a multi-product cloud-based deployment based on the Eclipse platform, highlighting our ability to provide integrated end-to-end solutions. Turning to market services. We achieved record annual net revenue of $1.2 billion, up 17% year over year, fueled by elevated volumes in US equities and US equity options as well as robust performance in European cash equities and equity derivatives. Our teams continue to execute well, capturing opportunities in value-added products, and extending our competitive positioning in both US and European markets. Specifically, in the fourth quarter, our index options revenue more than doubled year over year for the second consecutive quarter. We grew market share in European equities, and we delivered strong US Paid Plan revenue. Nasdaq's closing cross also set a new notional value record during the triple witch event in December with $233 billion traded. Success in 2025 reflects our ability to execute with discipline, innovate with purpose, and meet our clients' evolving needs. I've used the start of this year to meet with clients across the globe, including on the ground at Davos, listening closely to their priorities and pressure points. Those conversations have reinforced our view of the industry's priorities to manage risk, advance market structure, and innovate with AI, strengthening our conviction and the durability of our diversified business offerings. Looking ahead to 2026, Nasdaq is well-positioned to build on our strong foundation and deliver durable growth. Our platform is built on three core strengths. First, an embedded client community that connects us to real-world needs and builds trust that accelerates adoption. Second, gold source data that delivers unique client value powering intelligence, and advanced workflows. And third, engineering excellence that delivers speed, resilience, and interoperability at scale, enabling innovation, global deployment. Along with our deep industry expertise, these foundational layers work together to create a differentiated platform that delivers outcomes that matter to our clients. Our platform strongly positions us to take advantage of key growth areas in the age of AI. Sustained investment from leading technology firms and AI firms is continuing to reshape the economic landscape, making digital infrastructure and data-driven innovation the key drivers of business investment and real growth. By architecting the world's most modern markets, by powering the innovation economy, and by building trust in the financial system, we're not just responding to the change, we're shaping it. We look forward to updating you on our progress on these priorities at Investor Day next month. And with that, I'll turn the call over to Sarah.
