Thank you, Martin. Good morning, everyone, and thank you for joining the call. BlackRock's positioning and connectivity with clients are stronger than ever, and it's clear in our results. Our structural growth strategy resonated in the first quarter with secular growth across our businesses, even with a volatile market backdrop. We delivered above target 6% organic base fee growth, which represented our best start of the year since 2021, that's in a quarter where the S&P 500 ended 9% off its February peak. It's proof of BlackRock's enhanced structural strength, where we can power organic revenue growth that's undeterred by market movement. Revenues grew double-digit and are as-adjusted operating margin expanded by over 100 basis points. First quarter total net inflows were approximately $140 billion, excluding the episodic institutional index equity activity that Martin mentioned. Importantly, net inflows and organic base fee growth were well diversified across the entire BlackRock platform. We invested ahead of our secular growth opportunities and ahead of where our clients are going. This quarter represents the largest organic basic (ph) drivers, where strategies where we developed in just the last few years, including GIP, our digital asset offerings, Aperio, active ETFs as well as our tech and data driven systematic equity, equity franchise. Strength in our foundational businesses also underpinned results with a record start of the year for iShares, ETF and a 14% technology ACV growth. Uncertainty and anxiety about the future of the markets and the economy are dominating each and every client conversation. I was traveling in Europe last week when the sweeping U.S. tariffs announcements went beyond anything I could have imagined in my 49 years in finance. I wrote in my Chairman's letter last week that no system has done more to generate wealth for more people than the capital markets. As the capital markets have grown, more people than ever before our investing in the stock market. A little more than 60% of Americans own stock in one way or another, in mutual funds and ETFs and in individual shares and especially in their own retirement accounts like 401(k)s and IRAs. So this isn't Wall Street versus Main Street. The market downturn impacts millions of ordinary people's retirement savings. Their investments for a child college education and tuition or steps they're taking to have more financial stability. We're in a period of geopolitical and economic activity, but we have seen this before. When there are big pivots in the world, big structural changes in the market, like the financial crisis, like, the European debt crisis or COVID or the surging inflation in 2022, BlackRock stayed in front of our clients and made some of our greatest leaps forward. At BlackRock, we are -- we really challenge ourselves not to get mirrored (ph) down in all the negativity, but to navigate, to mitigate the move forward, to work with each and every client to help it each and every client. In recent weeks, we've connected with thousands of clients, providing them with real-time information and our views on unfolding events. BlackRock's expertise is built and delivered through our nearly 23,000 employees located in 30 plus countries. Together, they serve clients in more than 100 countries. The majority of our workforce is actually based outside the United States. Our international workforce includes people in our global platform centers in Europe, in India and our international commercial offices all across the world. This enables us to bring the global insight and investment strategies locally and to bring local insights globally. We need to be an American in the United States or German and Germany or Japanese in Japan or Canadian in Canada and Mexicans in Mexico. It's also to bring opportunities we see in each and every country to our global client base. It's contributing loyalty to build a country's capital market and retirement system and working for each and every client in each and every country. Probably 80% of what we bring to our clients, our clients are looking for a global, global strength, global expertise, they're looking for scale and operating efficiencies and investment talent. But it's the last 20% of the magic where it occurs. It's where you show the best of BlackRock in a local setting anywhere in the world. It doesn't matter whether the client is large or small or where they are, but to know that BlackRock is working for them, and we are -- and we show that we are working for each and every one of them. We're intentionally shaping our platform around the needs of our clients. And we talk about this in every quarter result. It's about the clients, building a premier global public-private market investment and technology firm. We've assembled a leading franchise across active strategies, ETFs, private markets, technology to serve the complete range of our clients' needs and to help them in each and every one of their own ambitions. Whether seeking capital preservation and cash and short duration or capitalizing on opportunities in equities or looking for income and uncorrelated returns in private markets, BlackRock's comprehensive offering is leading to clients consolidating more of their portfolio with them. I look at our cash business is one example of how we help clients manage asset allocation and liquidity. Our cash AUM is up at an all-time high as of April. Now it's at $950 billion. At BlackRock, we're always listening and deeply listening to each and every client and looking ahead to what their future needs will be. We're working with them on long-term issues, not the ups and downs of the market or the next tweet or the next issue. We're constantly testing ourselves to see where we need to do more, to be more different, to be faster, to be working on behalf of our clients. I said last quarter that it's just the beginning. The successful arcs of BlackRock of GIP and Preqin and soon HPS are all coming together in a shared story. GIP and Preqin employees moved into our BlackRock headquarters earlier this year, and we expect HPS to join shortly after the closing. It's one BlackRock physically and definitely one BlackRock spiritually. We're seeing how sensitive public markets are to uncertainty and how quickly they can move in reaction to policy proposals. These dynamics could drive even more capital flows into private markets as investors look to insulate portfolios from tariff impacts and seek attractive income and growth. Last year, we invested in enriching our private markets information, investments, data platform to serve our clients more. We are seeing the results today and are positioned for this type of secular growth as economic uncertainty plays out. In infrastructure, our combination with GIP just six months ago has already unlocked differentiated opportunities for our clients. Last month, we announced the largest infrastructure investment in our history. We have an agreement in principle to acquire a significant portfolio of 43 ports in more than 20 countries. We had a strong existing relationship with the seller of these assets and as a long-term shareholder. Our partners in this consortium includes Mediterranean Shipping Company, one of the world's leading -- leaders in shipping and logistics. And Terminal Investment Limited, which is one of the world's largest global container terminal operators. Upon closing on this deal, our consortium, our investors will have a portfolio of approximately 100 ports around the world. Together, we know how to invest in, own them, improve on them and operate them. We have recently expanded our AI infrastructure partnership, and we're excited to welcome xAI and NVIDIA, as partners alongside Microsoft and MGX. Since this announcement, AIP has attracted significant capital interest and advanced key discussions on AI infrastructure projects. The partnership will meet the expected target of $30 billion in capital from investors, asset owners and corporations. And over time, we believe this can unlock over $100 billion in investment potential, including debt financing of these infrastructure projects. Both AIP and the Landmark Ports announcement are early confirmations of the power and value of GIP pairing with BlackRock. It's unlikely either of us on our own would have been part of these transactions. At the heart of the GIP acquisition was our conviction in how our combined relationships, our combined expertise would come together and deliver fantastic investment opportunities for each and every client worldwide. We expect to scale our private credit AUM to approximately $220 billion following our planned acquisition of HPS. The opportunity set for private credit is expanding as a variety of borrowers from startups to large corporate partners seek more flexible execution as they evaluate their financing needs, and the longer duration lower risk returns of investment grade private debt are driving increased allocations from insurance companies. BlackRock already manages approximately $700 billion for the insurance industry, primarily in index public credit strategies and our Aladdin Technology powers over 100 different insurance companies. As Mark mentioned, our investment in Viridium is the latest example of our commitment to supporting partners through broad solution sets, including investments, capital and insurance expertise. BlackRock has a meaningful role in helping manage Viridium’s private market investments going forward, including in infrastructure investments and private credit. The upcoming addition of HPS represents even more opportunities to extend our insurance relationships across all private credit markets. We also expect HPS to advance our positioning in the quickly growing alts to wealth space, including through their approximately $20 billion of wealth focused BDC offerings. We've had recent success with our own non-traded BDCs, including placements with RIAs and with a large traditional distribution platforms. And we're looking forward to leveraging our shared expertise and expanded network to grow our combined franchises even further after closing. Our acquisition of Preqin brings leading capabilities in private market data to our technology platform and now triples our desktop reach to more than 300,000 users. We believe this acquisition enriches growth potential, not only for BlackRock private markets and technology franchises, but for the entire private market industry as a whole. Growth is diversified across our Aladdin franchise as clients are increasingly choosing to leverage the integrated capabilities of our public private market workflow and data offerings. It's more important than ever for our clients to have a clear, unified view of their portfolio from the building blocks of asset allocation to the minutia of trade execution and accounting. Aladdin recently went live with our first client in Korea, adding to our scaled relationships with leading institutions around the world. And looking ahead, we see more opportunity to expand our relationships with Preqin's more than 4,400 clients. BlackRock is a global firm, but one that operates hyper locally. We connect our clients across regions to both local and global to capital markets. The U.S. investment opportunity set is still going to be very relevant. We see our role outside the United States to both help our clients understand dynamics of the United States markets and enabling them to channel investments into their own capital markets. Strong local capital markets underpin the development of each and every country's robust retirement system. BlackRock is partnering with governments and sovereign wealth funds in these efforts. In India, we expect our joint venture with Jio BlackRock to launch later this year, subject to regulatory approvals. We believe we can transform access to investing for Indians, ultimately contributing to the development of our retirement system and a better financial future for each and every of our clients in India. In Saudi Arabia, we launched an investment management platform to partner with the public investment fund to drive capital into the local markets. It's managed by a dedicated BlackRock team in Riyadh. We're also working in the Kingdom to help develop a mortgage-backed securities market, an establishment of a secondary market for mortgage loans, which should help banks lower the cost of mortgages and home mortgages becoming more accessible for citizens in the Kingdom. In Europe, we are making it easier for more and more people to shift from savings to investing through ETFs and digital first offerings. Our European ETF platform crossed over $1 trillion for the first time this quarter and is well positioned for the future with approximately 40% market share by AUM. And the European ETF market has opened in 2025 with record demand. iShares European net inflows have more than doubled compared to the flows at this time last year. BlackRock iShares is well-positioned to capture significant upside in the coming years with our leading platform and diversified offering. We continue to innovate new products and new uses and recently brought our Bitcoin ETF to Europe. This builds on the success of our Bitcoin ETF launch in the United States last year and Canada in January. They continue to gain adoption with another $3 billion of net inflows in the first quarter. We see large opportunities for growth in digital assets and more broadly for blockchain and tokenization technology. Digital assets drove cash management net inflows this quarter as we continue to manage cash based reserves through our relationship with Circle. And BlackRock tokenized digital liquidity fund available on a public blockchain became the first Wall Street issued fund to cross over $1 billion in AUM and just recently surpassed $2 billion. BlackRock will continue to look for ways to push on-chain finance forward as part of our leadership in financial technology and innovation and in data. BlackRock's global scale, our relationships worldwide and locally and our industry-leading technology has made us the first call for more clients and more partnerships than any other time. They are seeking BlackRock to have conversations, it's not about the TikTok at any one single day of the market. They're looking to us to talk to them on long-term trends, working with them to help them design a portfolio that can be leading them for better futures. We're not a transactional organization. BlackRock has always remained to be focused on the long term with consistency, always there with capital. With corporations, we often have relationships at going back decades as long-term investors in their debt and their equity. And through our financial markets advisory practice, we're the adviser of choice that governments, central banks and other public and private capital market participants turn to when they need frameworks to support their economy and their capital liquidity. Since the financial crisis, FMA has been more trusted to counsel the Fed, governments of Greece in Ireland and Bank of Canada and so many others. We have a long history of providing guidance on practical targeted monetary and fiscal solutions in support of the global economy. We will continue to work with clients. We will continue to work with governments around the world to help them navigate develops in the economies and help them build out the global capital markets. I'd note that the market downturn this year is different from what we've seen in other shocks since the financial crisis. We do not see systemic risks, that there is not a pandemic. The financial system has shown it's safe and sound and the resiliency of the market of trading more volume with the liquidity than any other time. With all this volatility, the markets have proven to be quite successful and worked quite well. Obviously, there's near-term uncertainty, but the big macro trends that were in place 80 days ago, actually are still around. I know it's hard to believe only 80 days ago, but the mega forces like artificial intelligence, surging demand for global infrastructure and an ongoing evolution of debt financing presents transformative investment opportunities. Build outs of data centers and energy, the need for power grids in semiconductor plants and other infrastructure are beginning and are going to be growing dramatically over the coming years. Obviously, more policy clarity will help this uncertainty, but I remain very optimistic about the capital coming into the markets over the long term. I want to end by saying that I believe that we are in a better position -- better prepared today to meet our client demand at BlackRock than ever before. This is reflective of our depth, the quality of our dialogue and the deepness of our relationships and the length of our relationships with our clients worldwide. We are having the most -- the highest quality of conversations with our clients worldwide here in the United States than ever before. Actually, in markets like today, clients are putting even a greater premium on BlackRock and the differentiating value proposition that BlackRock can offer them. We have remained in good times and bad times, their trusted partner. I'd like to thank our employees for their steadfast focus on delivering for our clients and driving value for our shareholders. Once again, we're very proud that BlackRock generated 6% organic base fee growth against this very complex market backdrop, driven by categories that we've only invested in recent years like -- and the structural long-term growers like infrastructure, like ETFs and like systematic equities. We lead with a growth mindset. We lead with optimism. Long-term winners don't get bogged down in the pessimism. They break down barriers to find solutions to help build that optimism with each and every client over the long run. We try to see through the pessimism of the short run, and that is exactly what we are doing, and we're excited for the opportunity to do great work beyond today and tomorrow, throughout 2025 and going forward in the coming years ahead. I want to thank everybody. So operator, let's open it up for questions.
