Robert Scott Fauber
President, Chief Executive Officer and Director at Moody's
Thanks, Shivani. Good morning, and thanks, everybody, for joining today's call. Before I touch on a few key takeaways from our first quarter results, I'm going to start by saying how excited I am to be joined today by Noemie Heuland, who officially joined Moody's on April 1. And as I mentioned on our last earnings call, Noemie brings almost 25 years of global financial and accounting leadership experience at some very large public companies with a real depth of experience in technology and software as a service. And we're really fortunate to have her as our Chief Financial Officer, and I look forward to all of you getting to know her in the coming weeks and months. So with that, let me turn to our first quarter results. We delivered an impressive 21% revenue growth, capitalizing on a strong issuance environment and continued demand for our leading risk assessment solutions. We delivered strong top line performance and margin expansion in both businesses, and that translated to adjusted diluted ePS of $3.37 for the quarter. Now starting with MIS. Obviously, a great quarter. And over the last several years, you all have heard me talk about the investments that we've been making in analytical talent and technology enablement to ensure that we are the agency of choice for inventors and issuers, and in turn, position us to capitalize on more robust issuance periods.
And in the first quarter, we did exactly that, and we showed the tremendous operating leverage in our business with the second highest quarterly revenue on record, up 35% year-over-year and an adjusted operating margin of 64.6%. Meanwhile, MA reported another quarter of 10% ARR growth, growing across all lines of business, including double-digit ARR growth in both Decision Solutions and Data & Information. And during the quarter, we executed on our strategic investment road map across platforming, product innovation and GenAI enablement. And this quarter highlights the unique strength of our business model. We're tracking to our medium-term ePS target of low double-digit growth while we are funding this investment program that will drive future growth, all while we expect to return over $1.6 billion to stockholders this year through share repurchases and dividends. That is the power of the Moody's compounding machine. We're also updating a few of our guidance metrics, and Meanwhile, MA reported another quarter of 10% ARR growth, growing across all lines of business, including double-digit ARR growth in both Decision Solutions and Data & Information.

We're also updating a few of our guidance metrics, and Noemie will give some details on that a little bit later in the call. So we've got our eye on the ball, we're looking ahead, and we are focused on our mission to be the leading source of insights on exponential risk. So with that, let's dive in a little bit more on the financial performance of our businesses this quarter and our latest expectations for the full year. And as I've said before, MIS really is one of the world's great business franchises. It's widely recognized as best in the industry with strong global coverage in cross-border and domestic debt markets, and it has a growing range of offerings to support growth areas like private credit and transition finance. And maintaining that leadership position really is critical in order to capitalize on the resurgence and opportunistic issuance that we experienced during the first quarter. And that's what played out during the quarter. MIS delivered, as I said, growth of 35% in the quarter, including 57% growth in transactional revenue. And a key driver of this growth in the quarter was the leveraged finance markets, a real strength for MIS, where revenue was up 144% versus the prior year quarter. That's quite a growth number. And as I explained a few quarters ago, we established a dedicated private credit team in MIS, and that's starting to pay dividends as we're better positioned to service the continued growth of the private credit markets as well as a wave of deals refinancing from the private credit markets into public markets.
And while it's early, we're encouraged by interest in our transition finance offerings, and that includes our second-party opinions and our new net-zero assessment. And we already have several major issuers like electricite de France that have published our net-zero assessment. And with discipline around expenses, MIS delivered an adjusted operating margin of almost 65%, again, demonstrating the tremendous operating leverage in this business. Now while the first quarter issuance was very robust, it is still early in the year and there are some uncertainties. So we're a bit cautious in regards to changes to our full year outlook at this point in the year. Issuance in the first quarter benefited from pull forward, given the favorable market environment and questions about the back end of the year in regards to upcoming U.S. elections, ongoing tensions in the Middle east and uncertainty around U.S. inflation and central bank rate cuts. So consequently, we have not changed our full year issuance and revenue growth guidance targets. However, our updated outlook now centers on the upper end of both ranges. And there are some things that we're watching to determine if we've got some upside to our current outlook. The global economy has certainly demonstrated resilience, and that's also going to be reflected in declining high-yield default rates, which are now projected to range between 3% to 3.5% by year-end. And we see some strong investor demand for riskier assets that's kept spreads tight. Notably, we're starting to see M&A activity pick up.
Private equity funds are actively seeking exits and looking to deploy huge pools of capital. So again, there are some things that we're keeping a close eye on, and I'm sure we're going to discuss that a little bit further in the Q&A. So now turning to Moody's Analytics. As we've seen over the years, MA continues to be a very consistent growth engine for us, achieving 65 consecutive quarters of revenue growth and now six consecutive quarters of double-digit ARR growth. Our retention rate has held steady at 94% for the last two years and yet again for the first quarter of 2024, and that's a real testament to the stickiness of our solutions. As we look across our reported lines of business in MA, we can see our land-and-expand strategy in action. So starting with KYC, which I think you can see on the bottom far left of the webcast slide. About 1/4 of our 18% ARR growth in the first quarter is from new customer acquisitions. So a lot of new logos adopting our solutions in this space. On the other end of the spectrum, about 90% of our insurance ARR growth of 10% is from really strong execution of our cross-sell strategy across our existing customer base. Clearly, RMS is an important contributor to that, and it continues to deliver against the targets that we set back in 2021. And I think a number of you will remember that at the time of the acquisition, RMS was growing at a low single-digit pace, and it's moved up very nicely as we've made progress on migrating customers to our SaaS platform and really activating our cross-selling strategies. And that includes things like climate models to banks and conversely, selling data and analytics and other Moody's solutions to the RMS customer base. So when we take all of this into account, in 2024, the ARR for RMS, including synergies, is expected to grow at a low double-digit pace. Now switching gears a little bit.
Last year at this time, we were just starting to mobilize around GenAI. In fact, we hadn't even deployed our internal Copilot or announced our partnership with Microsoft at that point. And it is interesting to look back because what a difference a year makes. And we now have a framework for our suite of GenAI-enabled solutions that we're rolling out during 2024. It's no longer going to be just about Research Assistant. So we've categorized our capabilities into three primary buckets that we call navigators, skills and assistants. And really, each of these capabilities deliver increasing levels of value to our customers and are going to have some distinct economics. So navigators leverage an AI-powered natural language user interface to help our customers really get the most out of our products. And I would expect that almost all of our solutions will have some form of AI navigator or chat, what you might think of as a chatbot. And these will be table stakes, I think, for both our offerings as well as competitor offerings, I would assume in the relatively near future. Then we've got skills. Those are specialized GenAI capabilities that connect to Moody's data and content and analytics. And we're designing these skills to deliver automation and provide the tools to drive productivity and insight for our customers.
And that includes things like the planned release of our, what we call our QUIQMemo, which is our automated credit memo; and our QUIQAlert, which is our surveillance and early warning system. And then we're going to have a set of assistance for a number of our major customer personas, which are going to be a combination of skills and prompt engineering that are most relevant to their jobs to be done. So this go-to-market framework, I think, is going to address the needs of our customers as they move up the spectrum of GenAI adoption in their daily work processes. And while it is still too early to quantify, we now have a pipeline that is coming to market in the coming weeks and months. And we expect that to help drive our value proposition and retention rates and open up opportunities to serve new users. So on that note, I am very happy to hand it over to Noemie to provide a little more color on our results.
