Laurence Fink
Chief Executive Officer at BlackRock
Thank you, Martin, good morning, everyone, and thank you for joining the call. BlackRock is partnering with clients to navigate structural and secular changes in business models, technology, monetary and fiscal policies, always staying focused on each and every client goal. Through this connectivity, we were having richer conversations with clients than ever before about their whole portfolio, and in many cases deepening our relationships with them. This is driving accelerating momentum with a strong pipeline that has some of the best breadth of opportunities across all our client channels and regions that we've ever seen.
BlackRock's Integrated Investment Technology advisory platform and durable performance are resonating. In my conversations with clients around the world, I'm hearing about how they want to put their money to work, but they want to do it differently than they did in the past. They want their portfolios to be more holistically blending public and private markets, active in an index. They want their portfolios to be nimble, customized, text enabled. They want to work with fewer providers, or maybe just with one provider. BlackRock is the only asset manager that can partner in this way, having the most diverse integrated investment and technology platform in the industry. Clients around the world are choosing to do more with BlackRock, and this is resonating in our results. But I'm actually more excited about the building momentum we're seeing across our entire platform.
BlackRock's AUM ended the first quarter at a new record of nearly $10.5 trillion, up $1.4 trillion or 15% over the last 12 months. Also at that time, BlackRock has entrusted BlackRock with more than $236 billion of net new assets. BlackRock generated positive net flows across active and index and across all client types, and we grew our technology service revenues and ACV as clients leveraged Aladdin to support investments, processes and their entire platform. We've had a number of real large marquee wins in Aladdin, and are working on a number of significant new opportunities. Momentum remains strong as we grow with new and existing clients.
We continue to deliver sustained asset and technology services growth at scale. BlackRock's operating income was up 17% year-over-year, and we increased our margins by 180 basis points. Earnings per share were up 24%.
Activity is notably accelerating. As Martin said, we generated $76 billion of long-term net flows in the first quarter, which represents nearly 40% of last year's long-term flows in just the first three months of this year. And long-term net inflows across retail and ETFs and institutional active was actually $100 billion, which excludes the episodic institutional equity activity Martin mentioned. Some of these are public, some aren't, but over the last few months we've been chosen for a breadth of mandates from both wealth and institutional clients across regions that will fund over future quarters, and we're in active conversations on a number of unique broad-based opportunities, including several large mandates for Aladdin.
There is still a record amount of cash on the sidelines, and money market fund balances are now approaching $9 trillion. I think this stems from fear and uncertainty, but it's hard to achieve retirement or long dated objectives by holding cash. Clients worldwide are coming to BlackRock for advice on where and how to deploy their capital, and in many ways, how to help them reduce that fear and putting that money to work.
Being a growth company requires continued innovation, lots of investments and intense client focus. BlackRock has invested ahead of these themes. We believe will define the next decade of asset management. I see the greatest opportunities I've ever seen for BlackRock, for our clients and for our shareholders, and I'm very optimistic about the momentum into the rest of 2024 and beyond. The uncertain backdrop does not mean a lack of opportunities. Instead, we see great opportunities for investors across a number of structural trends with near term catalysts. These include rapid advancements in technology and AI, the rewiring of globalization, accelerated economic growth in certain emerging markets, and an unprecedented need for new infrastructure. BlackRock is connecting with clients to these opportunities and providing them the confidence to continually investing in the long run.
In a world where clients are looking for more certainty, the higher coupon, longer duration returns of infrastructure private markets are increasingly becoming more attractive. Demand for all forms of infrastructure is surging around the world, from telecom networks to power generation, to transport hubs for data centers and new ways of securing energy. Over the last 12 months, BlackRock's infrastructure platform has delivered 19% organic asset growth. BlackRock's infrastructure franchise and our private markets business more broadly benefited from the firm's global footprint, our deep network of clients and distribution relationships, and access to high quality deal flow.
As we spoke in January, we believe the planned combination of BlackRock's infrastructure platform with GIP will provide clients with access to market leading investments and operating expertise across infrastructure private markets. We have a deep conviction that this plan combination will be another transformational moment for BlackRock. It will be another example in our long-term history of staying ahead of client needs, positioning ourselves against accelerated macro trends. I believe infrastructure private markets are approaching the upper trajectory of their J curve, just as ETFs did when we announced our acquisition of BGI and iShares nearly 15 years ago.
We always viewed ETS as a technology that facilitated investing. Since our acquisition of iShares, BlackRock has led in expanding the market of ETFs by making them more accessible, by delivering new asset classes like bonds, investment strategies like Active. As a result of that success, the ETFs evolved beyond what started as an indexing concept, it is recognized as an efficient structure for a range of all investment solutions.
First quarter ETF net inflows of $67 billion reflected sustained client demand across our client categories, led by core equity and bond ETFs. ETF flows demonstrated accelerating activity, with March accounting for more than half of the quarterly net inflows, and our flows in the month were 80% higher than the next largest issuer.
We continue to innovate across our ETF platform to give our clients better access to the most diverse range of exposures in the industry. Our bitcoin fund, which was launched in January, was the fastest growing ETF in history, and already has nearly $20 billion in AUM. Our active ETF drove $9 billion in net inflows in the first quarter, led by our equity factor rotation and flexible income ETFs, these products offer alpha generation with some of our leading investors at BlackRock in a more efficient, more transparent ETF wrapper. Across BlackRock, we continue to scale our product offerings to democratize assets' [Phonetic] new strategies, increase transparency, and drive cost efficiency. To that end, last month we announced the launch of our first tokenized fund, as well as our minority investment in Securitize, a blockchain based tokenization platform. This builds on our existing digital asset strategy, and we'll continue to innovate in new products and wrappers, all with the aim of providing greater access and customization to each and every of our clients.
We continue to see demand for customization with our own wealth business. As financial advisors and their clients, they serve increasingly turn to SMAs to personalize their portfolios. We acquired Aperio three years ago in anticipation of this trend, and organic growth in that business has been over 20% since our acquisition. To further boost our SMA capabilities, we announced our planned acquisition of the remaining equity interest of SpiderRock, as Martin discussed.
Among wealth clients, we are also seeking to renew demand for our high performing active fixed income strategy, with particularly strength in high yield and unconstrained bond funds. In the post QE market, we see more opportunities ahead for active management with greater potential for selective risk taking to generate superior returns. Quarterly active net inflows of $15 billion reflect strength in systematic equities and fundamental fixed income, including the funding of several institutional outsourcing mandates. Across our active franchise, BlackRock has delivered durable investment performance with 82%, 90% and 93% of our fundamental equity, systematic equity and taxable fixed income AUM above benchmarks or peer medium for the last five years.
Our active investment insights, our strong investment performance, our integrated Aladdin technology differentiates BlackRock and ultimately drives better outcomes for our clients. We first built Aladdin as a risk management enabler, empowering investors to better understand their portfolios through technology. Today, Aladdin is much more than that. Our clients are leveraging Aladdin as a whole enterprise operating system, connecting multiple asset classes, data, technology partners on a single platform. Aladdin's integrated offering continues to resonate with a majority of our sales this quarter spanning multiple Aladdin products. We are in a late-stage conversation with several large potential Aladdin clients, and we look forward to executing on more opportunities ahead to be bringing the benefits of Aladdin to new clients and by expanding relationships with our existing clients.
From the early days of developing Aladdin to now managing nearly $10.5 trillion across our platform, our ambition has always been to help investors benefit from the growth of the capital markets and achieve financial futures that they seek. More than half of the assets we manage are related to retirement, making this an outcome central to many of our client conversations. BlackRock has been at the forefront of innovation and advocacy for retirement solutions for years. In fact, we pioneered the first Target Date fund called LifePath back in 1993. When we introduced the concept, it was revolutionary, eliminating some of the guesswork for retirement savings by automatically adjusting their investment mix over their timeframe. Fast forward 30 years, Target Date funds have become the most common default investment option in defined contribution plans in the United States, where we're entrusted to manage the retirement assets of 35 million Americans.
We continue to evolve LifePath to help deliver the retirement outcome participants need. That has meant introducing LifePath options in new countries and in new wrappers such as LifePath Target Date ETFs we launched last year. Our LifePath Target Date franchise now has nearly $470 billion in assets, and has risen over $115 billion in assets just over the last five years.
In addition to helping people save for retirement, we also worked to expand the LifePath solution to help people spend throughout their increasingly longer retirement. Society focuses a tremendous amount on helping people live longer and healthier lives, but spend just a fraction of that time and effort on helping them afford those extra wonderful years.
The shift from pension to defined contribution models have put the large -- as the large burden on individual savers. They have to first build up their retirement estate, which in and itself is a formidable challenge. Then, even as they have this sizable savings at retirement, there's not much guidance about how to spend and how not to overspend these savings. We've been working for years to address this de-accumulation challenge, and we believe this will help increase hope in America. In 2020, we announced the LifePath Paycheck, the next generation of Target Date solutions. It will include an option to purchase a lifetime income stream from insurers selected by BlackRock, and is expected to go live towards the end of the month. We are partnering on implementing LifePath Paycheck right now with 14 plan sponsors representing over $25 billion in target date AUM, and now have a half a million participants. It will pair the flexibility of a 401(k) investment with the potential for a predictable paycheck life income stream, similar to a pension. I believe it will be in one day the most used investment strategy and defined contribution plans. This pioneering structure can help address global gaps in funding retirement security, improve the quality of life in retirement for millions of Americans, and bring back hope for those who are retiring.
It's been four years since the start of the pandemic and the subsequent geopolitical upheavals. Leaders of countries, leaders of companies need to create hope for the future for all of their stakeholders. That's certainly what we're doing at BlackRock. I've spoken before about the fear we see today, some of it stoked by increasingly political polarization in the world. Our industry and BlackRock have been a subject of political dialogue, mostly in the United States. We recognize some of this with being the industry leader. We have done a better job now of telling our story so that people can make decisions based on facts, not on lies and not on misinformation or politicization by others. Unfortunately, there's still others out there who put short term politics, who continuously lie about these issues. They're putting those issues above the long-term fiduciary responsibilities.
As a fiduciary, politics should never outweigh performance. I do believe that with a vast majority of our clients, our long-term fiduciary approach and performance are resonating. We hear it in our dialogue with them and we see it in our flows, and I know all of you as shareholders see it in our flows. Over the last past five years, clients have entrusted BlackRock with an aggregate of $1.9 trillion of total net inflows, $1 trillion over the last three years, and nearly $300 billion last year.
It has been in the United States, where client led inflows in every one of these periods. It is true also in the first quarter of this year. This is in all is in the environment where the industry has experienced flat or negative flows, BlackRock saw inflows. Our sustained growth, our accelerating momentum, are made possible by the trust of our clients and shareholders, and the dedication of all the BlackRock people. Across our firm, we're delivering BlackRock to meet all our clients' individual needs. We're helping each and every client unlock their new opportunities, and the power of BlackRock's integrated platform has enabled us to drive better outcomes from each and every client, and providing them a differentiating growth for them, which then entails providing differentiating growth for you, our shareholders.
I believe at this time our momentum has never been stronger. The opportunity we have in front of us has never been stronger, and I look forward at BlackRock to be delivering on a significant broad base of opportunities across the world, across our platform, across all of our products, and delivering the responsible fiduciary responsibilities that we provide to each and every client.
Operator, let's open it up for questions.
