Good morning, and thank you for joining us today. Against the backdrop of escalating uncertainty around trade policy and economic growth, AllianceBernstein Holding L.P. delivered another strong quarter. Our results highlight the strength of our franchise, the depth of our investment expertise, and the breadth of our globally diversified platform. On slide three, I'll review the key business highlights of our first quarter. First, all three of our distribution channels grew organically in the first quarter, generating $2.7 billion in firm-wide active net inflows. Our differentiated distribution platform gives us an edge in growing markets like Asia, US high net worth, and insurance, where we've consistently gained market share, including in the first quarter of 2025. Coupled with the extensive range of our investment capabilities that span across traditional and alternative assets, we're strategically positioned to help our clients navigate turbulent markets and benefit from rapidly emerging trends. Fixed income reallocation theme is a prime example of our ability to capture demand where it exists, having generated over $35 billion of active income inflows over the last two years. Even amidst the return of rates volatility and heightened policy risk, we successfully generated $1 billion in active fixed income inflows during the first quarter of 2025. Despite the downturn in overseas demand for our taxable fixed income strategies, largely driving a $1.4 billion in firm-wide taxable outflows, we continue to enjoy robust growth for our tax-exempt franchise, which generated $2.4 billion of inflows. Our industry-leading retail meeting platform has been a driving force of organic growth, achieving an impressive 19% annualized growth rate in the first quarter. Over the past five years, Retail Tax exempt has consistently grown at double-digit rates, reaching $46 billion in AUM, more than doubling in size since 2020. Secular growth and private alternatives is another theme that benefits us. During the quarter, we had over $2.5 billion of institutional deployments into our private markets platform, coupled with inflows from high net worth into our asset-based finance and private credit strategies. Active equity outflows of $2.5 billion moderated compared to recent quarters, with institutional redemptions slowing down while retail flows flipped back to positive. In the first quarter of 2025, we generated $500 million of retail inflows driven by solid demand for our U.S. Large Cap Growth, Global Strategic Core, U.S. Select, and our Security of the Future strategies. Secondly, we are actively expanding our private market platform by deepening existing partnerships, establishing new ones, and diversifying the growth avenues of our business. Our fee-paying and fee-eligible assets under management have reached $75 billion as of quarter-end, marking a 20% increase compared to a year ago. We have successfully deployed nearly 40% of Equitable's second $10 billion commitment and are leveraging our expertise to extend the addressable market with institutional and retail-oriented solutions. We are replicating the success of our evergreen capabilities in the middle lending that have been historically marketed within our private wealth channel. We're excited with the momentum we're seeing as we extend our private credit franchise to the institutional channel with customized solutions. In asset-based finance, we're expanding our retail offerings to help our own private wealth clients access this exciting new asset class while also venturing into new distribution platforms. Our credit opportunities interval fund has exceeded $200 million in assets under management, including allocation from third-party retail clients. In the first quarter, we've engaged with nearly a dozen new RIAs, and we're encouraged by the increasing number of advisors exploring alternative investments with AB. We continue to leverage our strong local relationships in the RIA channel. We already partner with national aggregators and independent advisers in areas such as municipal bonds. Third, our diversified asset mix coupled with our enhanced operational efficiency provides downside protection to our revenue base and to our margins. As asset managers, we value diversification, and we've developed an all-weather platform that mitigates concentration risks by geography or asset class. With liquid and illiquid credit accounting for nearly half of our assets under management, we believe we're less vulnerable to significant equity market downturns. The strategic initiatives we completed last year optimized our expense structure to expand the upside from favorable market conditions while also fortifying our business against downturns. We enter a turbulent market environment from a position of strength. Fourth, we have a durable base fee rate that has held relatively steady over the past several years. Our all-in fee rate, including base and performance fees, is another differentiating factor for AB. This relative stability results in symmetrical growth between our management fees and our AUM. Moving on to slide four. I'll highlight our strengthening relationship with Equitable. We firmly believe that being affiliated with a leading insurance provider is a competitive advantage for AB. Leveraging the permanent capital commitment from Equitable allows us to seed and scale our higher fee, longer-dated private alternative strategies. Investment-grade quality private credit is a key growth opportunity for both Equitable and AllianceBernstein Holding L.P. We've now deployed nearly $14 billion of the $20 billion committed by Equitable. This has enabled us to build out new capabilities like residential mortgages and private ABS, which we intend to expand with our other insurance and institutional clients. We continue to scale our distribution, leveraging our leading brand awareness and our expertise in vehicle versatility to expand our third-party growth avenues. This virtuous circle of delivering additional yield to our partner's balance sheet while seeding new strategies with permanent capital enables AllianceBernstein Holding L.P. to sustainably expand our business. We remain on target to grow our private market AUM to $90 billion to $100 billion by 2027. Slide five reflects a summary page with our key financial metrics. Tom will follow up with more commentary on our results. Turning to slide six, I'll review our investment performance starting with fixed income. Despite resurgent rates volatility driven by inflationary pressures caused by policy uncertainty, bonds served as a safe haven during the first quarter of '25 with Bloomberg's U.S. Aggregate index returning 2.8%. Our fixed income performance benefited from active duration management and our allocation to investment grade. While our security selection within high yield detracted from relative performance. Overall, our performance improved with 64% of our AUM outperforming over the one and three-year periods, while 81% outperformed over the five-year period. Quarter-to-date dynamics have been tumultuous with markets reacting sharply to tariff headlines, global growth uncertainty, and shifting demand for US treasuries. Despite policy risks intensifying and credit spreads widening to levels reminiscent of the regional banking crisis in 2023, fixed income is proving relatively resilient compared to the significant drawdowns we've seen in US equity markets. For example, at the peak of the drawdown caused by a tariff announcement, the S&P 500 was down 15%, while the US high yield index was down less than 2%. While the elevated rate volatility made down sentiment and appetite for duration, we view the value proposition for fixed income as intact. Specifically, we see the belly of the yield curve as an attractive spot to manage duration risk given the ongoing buildup of term premia. Credit remains an area of opportunity with all-in yields over 8% presenting an appealing risk-adjusted return profile compared to long-term equity forecasts. With policies still in motion, markets may continue to react faster than fundamentals, creating dislocations as well as opportunities for new investors. In this environment, we're constructive on fixed income, and we have the right strategies to compete for the next wave of the reallocation. Turning to equities, near record high valuations in US equities combined with a dimming economic outlook for the US arising from a changing trade policy triggered a rotation into international equities. The percentage of AUM outperforming over the one-year period deteriorated to 23%. The shift was primarily driven by our U.S. Large Cap Growth fund distributed in Japan flipping from above to below median. A significant factor contributing to this change was the strengthening of the yen during the quarter, impacting comparisons against other local growth managers. The three-year figure had improved to 52%, while the five-year declined to 45%. This performance trend reflects the market dynamic of the excessive concentration in a few mega cap names within the AI scene. Our investment focus on companies demonstrating consistent growth with a disciplined approach to valuation also posed challenges in the later half of 2024. Year-to-date, despite the volatility following the tariff announcements in April, our active platform has demonstrated significant relative performance. U.S. Large Growth has generated nearly 300 basis points of relative outperformance, positioning it near the top decile year-to-date. Our strategic core portfolio is designed to offer downside protection in volatile environments, having outperformed their benchmarks by 300 to 400 basis points year-to-date. Furthermore, our global, international, and emerging markets portfolios have established track records that have exhibited strong performance. Additionally, our US core strategies, select equities, and US strategic equities have continued to deliver robust returns following a successful year, showcasing their ability to generate alpha across various market conditions and attracting client interest. Overall, we had eight active equity strategies that generated over $100 million in inflows during the first quarter of 2025. Now turning to slide seven. Retail posted its seventh straight quarter of positive net flows, with sales continuing to track at record pace levels, offsetting elevated redemptions during a turbulent quarter. Actively managed asset classes were inflowing in the first quarter, led by enduring organic gains in tax-exempt, solid inflows into multi-asset, and modest inflows into active equities. We continued to gain retail market share in tax-exempt for the ninth consecutive quarter, growing at a 19% annualized rate. Our all-market income strategy drove multi-asset sales in the first quarter, particularly out of the Asia Pacific region. Active equity also grew organically, supported by continued inflows into our US Large Cap Growth strategy in addition to Global Strategic Core and U.S. Select Equity. Thematic investing is another area with significant potential. Our Security of the Future portfolio continues to attract solid inflows, surpassing $1 billion in AUM just one year since we launched. Diversifying our product offerings remains a cornerstone of our distribution strategy, and we're very pleased with the early success we're seeing as we scale our services across our global footprint. Offsetting our organic gains are taxable fixed income franchise posted outflows of $1.4 billion, primarily as our marquee income strategies AIP and GHG had outflows given the uncertain rate outlook. Base management fees grew 10% year over year, reflective of market growth and organic flows, while they were down 3% versus the prior quarter due to the equity drawdown. Organic base fee growth was 2% over the last twelve months and slightly below 1% as of the first quarter. Moving to slide eight. Institutional sales inflows rebounded in the first quarter of 2025 to the highest level since the fourth quarter of 2022, breaking a streak of persistent outflows. Channel inflows were driven by an accelerated pace in alternative deployments across various services, including private placements, commercial real estate debt, residential loans, and CLOs. Active equity outflows of $1.9 billion in the quarter moderated versus recent trends. Our pipeline grew to $13.5 billion in the first quarter, up $2.8 billion sequentially, reaching its highest levels in the seventh quarter. Note that institutional fundings also accelerated roughly $3 billion in pass-through mandates that were not captured within our pipeline. The decrease in the pipeline fee rate was mainly attributed to the addition of the sizable lower fee mandates, including an $800 million in passive index equities and $1.1 billion in systematic fixed income. Our ongoing efforts to market our systematic strategy continue to attract strong client interest, enabling us to grow our institutional market share in fixed income. However, these mandates tend to be lower fee and will impact the pipeline fee rate. Turning to slide nine. Private wealth posted solid inflow in the first quarter, growing to an annualized organic growth rate of more than 2%, the fastest pace in two years. As a reminder, our private wealth net inflows exclude reinvested dividends and interest income, which is typically reported within net assets across key wealth management peers. Our organic growth was fueled by increased sales momentum, underscoring robust client engagement and adviser productivity. We're still focused on supporting and growing our adviser sales force, ramping up our recruiting effort in line with our long-term target of 5% headcount growth. Demand dynamics within the channel were positive across all asset classes except for active equity. Fixed income inflows exceeded $800 million, driven by our muni tax-aware strategies, money markets, and Global Plus. Solid demand for our passive tax harvesting strategy led to $600 million in inflows into passive equities, growing organically at nearly a 10% annualized rate. Alt's MAS inflows of nearly $500 million, growing at a 7% annualized rate, marked the eighth consecutive quarter of organic growth through alternatives and multi-asset within Bernstein. Private alternatives, including real estate debt, CarVal, and private credit, accounted for approximately half of those inflows. Fundraising and private alternatives continued to be a significant driver for channel activity, with approximately $400 million raised in the first quarter. Base management fees grew 10% year over year and came in flat sequentially. Channel revenues were up 6% versus the prior year and down 17% quarter over quarter, primarily due to performance fees typically crystallizing in the fourth quarter. Before moving on to our financial review, I'm delighted to introduce our newly appointed CFO, Tom Simeone. Having had the privilege of collaborating with Tom for several years, I'm eager for our unitholders, analysts, and all stakeholders to have the opportunity to become acquainted with him. Tom?
