Thank you, Henry, and greetings, everyone. In my remarks today, I will discuss our first quarter performance by client segment, including meaningful business wins that give us conviction in our global strategy. We delivered encouraging results among established and newer segments. Among hedge funds, MSCI Inc. achieved 14% subscription run rate growth driven by analytics and index, and covering a wide range of products and capabilities including customization and the reimagining of risk. For example, our next-gen factor models and analytics are helping a growing number of hedge funds understand the key fact amid high levels of market volatility. We now have more than 60 hedge funds using those models, up from just 8 in 2022. We also completed a significant multi-region hedge fund deal for our ETF-linked custom index module. Amongst banks and broker-dealers, delivered over 9% subscription run rate growth with strong analytics, new recurring subscription sales in Europe and the Americas. In particular, we saw robust demand for our factor models related solutions, confirming the importance of our risk analytics tools during periods of market volatility. We also saw strong demand for custom baskets created with MSCI Inc. Index Solutions, another sign of the growing push for customization. In addition, completed a multiyear deal with a large bank in the Americas for a sustainability and climate regulatory solution that can support asset liability management. This last win demonstrated that MSCI Inc. can generate enormous value across climate risk and sustainable finance. Turning to wealth managers, we achieved subscription run rate growth of 15% driven by index across all regions and by sustainability and climate in Europe. For example, we landed a large MSCI Inc. win including index and private capital solutions, with the wealth arm of a prominent global financial institution. This win came as part of a seven-figure multilocation renewal deal that spans seven countries and broadened the scope of an existing client relationship, resulting in a client run rate expansion of almost 38%. In the process, we fully displaced the equity benchmarks of two key competitors. We also secured a large multiyear sustainability climate win with the European wealth manager to expand their integration of sustainability at both the home office level and in client portfolios. Meanwhile, direct indexing AUM based on MSCI Inc. indexes increased by 30% to more than $131 billion. All of this illustrates how MSCI Inc.'s wealth solutions cut across product lines and meet different use cases for a growing number of clients. Moving on to asset owners, we delivered subscription run rate growth of 12% driven by analytics and private capital solutions. Notably, we achieved 10% run rate growth among asset owners in analytics and with particular strength in the Americas. We also completed several large private capital solutions deals with pension funds in the Americas and Europe. These deals helped us drive 24% recurring net new sales growth in the overall PCS product line. Additionally, asset owners and other clients continue to adapt MSCI Inc. indexes to support their climate strategies. In Q1, assets under management in ETF and non-ETF products linked to MSCI Inc. climate indexes grew by 50%, reaching $387 billion in total. Finally, shifting to asset managers, our subscription run rate growth remained steady at around 5% driven by index. We achieved a retention rate of 96% with asset managers in Q1, up from 95% a year earlier. In our most notable business win, we completed a seven-figure index deal with the asset management arm of a major European bank who made MSCI Inc. their exclusive partner and index provider for all future passive ETFs. This deal also included access to our fixed income issuance weighted module and our fixed income custom index. Looking ahead, MSCI Inc. is redoubling our product development efforts to meet asset managers' rapidly evolving needs, especially around active ETFs and fixed income. In summary, MSCI Inc.'s increasingly diversified portfolio of clients, products, and services strengthen our all-weather franchise. And with that, let me turn the call over to Andy. Thank you, Baer. And hello, everyone. In these times, our global frameworks must have content and trusted risk and performance tools are essential for understanding and navigating markets. And our relationships with the world's leading investment institutions are deeper than ever, positioning us to help them navigate global markets. With 98% recurring revenue, strong margins, and high cash flow conversion, we have a highly resilient financial model that positions us for strength in all environments. In index, subscription run rate growth was 9%, with asset managers growing nearly 7% and asset owners growing over 10%. These two client segments comprise almost 70% of our index subscription run rate. An index subscription run rate growth with hedge funds, wealth managers, and banks and broker-dealers was 22%, 16%, and 11%, respectively. Please note that beginning this quarter, our investor slides will show a slightly different presentation of our index subscription run rate. This new categorization, which now breaks out the run rate across market cap weighted products, non-market cap weighted products, and custom index products, is intended to provide better insights into the growth dynamics across key offerings, especially the custom index offerings. The most notable change from the prior categorization is that the run rate from special packages is now primarily included in the market cap weighted category. In non-market cap weighted run rate primarily includes our standard factor, sustainability, and climate modules, which span both equities and fixed income offering. As you can see in our presentation, subscription run rate growth from custom index was 15%. Asset-based fee revenue grew 18%, aided by stronger flows into international exposure products, an area where MSCI Inc. has particular strength. Non-ETF AUM linked to MSCI Inc. indexes nearly $3.9 trillion, growing 20% year over year. MSCI Inc. linked equity ETFs had an ending balance of $1.78 trillion at the end of March after attracting nearly $42 billion of inflows. $37 billion of the inflows went into products linked to MSCI Inc. DMX US, EM, and all country exposures. Categories where MSCI Inc. collectively captured roughly 45% of all inflows. These cash flows represent the second strongest quarter since 2022, behind only Q4 of last year. Our strong asset-based fee growth also benefited from growth in fixed income index products. Fixed ETF AUM linked to MSCI Inc. and partner indexes is now over $76 billion, growing 20% from a year ago. In analytics, subscription run rate growth was 7%, reflecting continued momentum in equity analytics and solid growth with hedge funds, trading firms, and asset owners. Similar to last quarter, we expect analytics revenue growth to be in line with to slightly lower than run rate growth in Q2 as we compare to periods last year when we had meaningful contributions from implementation-related revenues. In our sustainability and climate reportable segment, previously referred to as the ESG and climate segment, we drove almost 10% subscription run rate growth, reflecting some large deals in banking that we previously spoke about supported by 14% growth with both asset owners and wealth managers. Our long-term target for this product line remains under review, as we assess the impact of the near-term environment on the long-term trajectory. That said, we're seeing traction on several fronts, including with our geospatial asset intelligence solutions where we've had several recent wins. The retention rate of 94.5% for the segment highlights that our sustainability and climate tools remain mission-critical. As a reminder, in the second quarter, we will be lapping the prior year benefit from the Moody's partnership, which had a significant contribution to last year's sustainability and climate new recurring sales. Private capital solutions saw a 24% increase in recurring net new sales and continued mid-teens growth of our run rate, reflecting steady interest in our data, performance, and benchmarking solutions. Real assets, overall activity remain muted. We continue to face headwinds related to client consolidation, particularly among brokers and developers. On the capital allocation front, we've repurchased over $275 million of MSCI Inc. stock or over 493,000 shares since the start of the year. This reflects our opportunistic approach to capital deployment and our belief in the long-term value of the franchise. We have a strong balance sheet with our gross leverage ratio now at 2.6 times the last twelve months adjusted EBITDA. Our guidance is unchanged. In this complex operating environment, we are preparing MSCI Inc. to navigate a broad range of possible outcomes. As we mentioned last quarter, our guidance assumed that market levels gradually increased throughout the year. To the extent markets remain at their current levels, we would expect expenses to be at the low end of our current guidance ranges. As a reminder, we have various expense playbook levers that we can rapidly flex. These include but are not limited to managing the pace of hiring, flexing non-comp and professional fees. Additionally, our incentive comp remains self-adjusting with overall financial performance. Our Q1 effective tax rate of 12.8% reflected the benefit of significant discrete items as we previously indicated. Beyond Q1, we expect the quarterly effective tax rate excluding potential discrete items to be in the range of 19% to 21% each quarter for the rest of 2025. Our Q1 performance adds to our track record of consistent, durable financial results. The long-term secular opportunities remain intact. We remain laser-focused on anticipating the needs of the investment community as market conditions evolve. With that, operator, please open the line for questions.
