Robert Fauber
Thanks, Shivani, and thanks, everybody, for joining today's call. I'm going to start with the highlights.
And 2025 was a record year for Moody's. It was driven by consistent execution against the long-term demand trends that we've discussed over the last several years.
We finished the year with strong fourth-quarter performance across both Ratings and Analytics, and delivered robust growth and meaningful capital returns to shareholders. Now, we're scaling decision-grade contextual intelligence embedded directly into customer workflows across our platforms, third-party systems, and AI-enabled interfaces so that we're present where critical decisions get made.
As technology and the ways of working continue to evolve, we enter 2026 well-positioned and confident in the opportunities ahead. Now, we had strong top-line performance across the company in 2025.
Total revenue exceeded $7.7 billion. That was up 9% year-over-year, and 9% in both Ratings and Analytics.
We expanded adjusted operating margin to 51.1%. That was up 300 basis points as we drive further operating leverage into the business.
These results are being driven by sustained customer demand for our decision-grade data, analytics, and insights amidst very large funding needs, greater market complexity, heightened risk and resilience needs, and compliance requirements. Now, adjusted diluted EPS reached a record $14.94.
That was up 20% year-over-year. That represents a 70% earnings growth over the past 3 years.
That's something like a 20% CAGR since 2022. Now, let me turn to Ratings.
Issuance and investment cycles came together very powerfully in the fourth quarter. It resulted in the busiest fourth quarter in our history.
The investments that we've made over several years have really positioned us to capitalize on this activity, and that drove record revenue this past year. In 2025, we rated $6.6 trillion of debt.
That was an all-time high, supporting investment across infrastructure, AI-driven data centers, energy transition finance, and private credit. In the fourth quarter alone, we rated more than $70 billion of issuance for companies including Alphabet, Amazon, and Meta, in part related to their AI investment programs.
Moody's was named Best Credit Rating Agency in the U.S. by Extel again.
That's for the 14th consecutive year. That really reflects our role at the forefront of global debt markets.
In December, we issued a request for comment on a cross-sector stablecoin rating methodology. As the use of tokenized cash continues to accelerate, the total value of issued stablecoins is forecasted to reach $400 billion by the end of 2026 and $2 trillion by 2028.
Our methodology, which is the first such framework from a credit rating agency, will position Moody's to play an important role in the digital finance ecosystem. Now, in private credit, demand for ratings continues to accelerate.
Private credit revenue in MIS grew by nearly 60% in 2025, reflecting both market growth and our expanding role in the sector. We developed new methodologies and deepened our analytical and commercial engagement to capture rising demand for transparent, independent credit assessment.
That momentum is translating into tangible wins. Last year, we were the sole rating agency on the largest private credit CLO of the year, a $1.5 billion issuance by Blackstone.
Now pivoting to Moody's Analytics, we finished 2025 on a strong note there as well. We delivered net growth that outpaced the fourth quarter of 2024.
This performance included meaningful contributions from our highest-priority growth areas. That includes our lending and credit decisioning solutions, as well as decision-grade KYC data.
We also closed the year with strong momentum in AI-related sales ranging from specialized workflow agents to AI-ready datasets. I'm going to talk about that in just a few minutes.
Importantly, our strongest growth came from our largest strategic customers. These customers contributed over 30% of the total MA net growth in the fourth quarter, and for the full year, grew at twice the rate of the rest of the MA customer base.
This is durable, high-quality growth with clear evidence of customer adoption. I want to emphasize durable because the nature of MA's revenue growth is increasingly recurring and scalable.
Recurring revenue grew 11% and represented 97% of fourth-quarter revenue. This, combined with some real execution discipline, enabled us to deliver 190 basis points of margin expansion and an adjusted margin of almost 36% in the fourth quarter.
We set our focus on scaling MA's recurring revenue base a few years ago, and now we're making further proactive adjustments to our portfolio to reinforce that strategy. In December, we closed on the sale of our Learning Solutions business that was primarily reported as transactional revenue, and it really was no longer core to our strategy.
We also announced the sale of our regulatory reporting business, which served customers with relatively limited cross-sell opportunities across other banking offerings. Underpinning all of this is our commitment to delivering best-in-class solutions.
That commitment was reinforced by our recognition as the number one provider in the Chartis RiskTech100 for the fourth consecutive year. That reflects the trust that customers place in Moody's to support workflows and decisions that matter most.
We see that market recognition reflecting a broader truth, that as AI becomes a new interface for decision-making, the need for trusted context increases, not decreases. AI systems require verifiable, permissioned, domain-specific data and analytics to produce outputs that are accurate, explainable, and defensible.
That's exactly what Moody's provides, and it gives us the opportunity to become even more deeply embedded in customer workflows. We see this clearly in recent customer behavior.
Customers who have purchased or upgraded into at least one standalone GenAI or agentic solution are retained at a rate of 97% and are growing at roughly twice the rate of the rest of the customer base. This isn't experimental usage.
AI adoption is driving greater consumption of our proprietary data, expanding our share of wallet, and reinforcing long-term customer economics, particularly amongst our largest strategic accounts. A key reason for adoption that is accelerating is how customers consume our intelligence.
Moody's solutions are delivered through our own applications, and increasingly, they're embedded directly into customers' existing technology stacks and third-party workflow platforms. That includes systems like Salesforce, ServiceNow, Coupa, Intapp, Databricks.
We've made our content available through smart APIs and MCPs and specialized agents for consumption through our customers' own AI platforms and, going forward, through AI portals like Claude and OpenAI. This is enabling us to serve our customers on a different level and in different ways than ever before.
For our banking customers, AI-enabled workflows such as automated credit memos and early warning systems are delivering some material efficiency gains, reducing cycle times while improving consistency and regulatory compliance. Our flagship lending solution that we call CreditLens remains the fastest-growing product in the banking portfolio, with growth approaching 20% in 2025.
I have to tell you, our new packaging is working. Roughly two-thirds of eligible renewals converted to our AI-enabled lending suite in 2025, with an average uplift of about 67%.
In the fourth quarter, we also sold a large globally systemically important bank our GenAI-ready data and smart APIs to embed into their digital credit platform in order to automate financial analysis and accelerate wholesale lending decisions. A Tier 1 U.S.
bank has deployed Moody's agentic solutions to automate credit memo creation. They've told us that it can generate roughly 35% to 40% of each memo and saves analysts hundreds and hundreds and thousands of hours of time, equating, in some cases, to millions of dollars saved.
That work is expanding into enabling real-time commercial real estate risk monitoring, API-based screening, and KYC, where we displaced a competitor in the fourth quarter. The same holds true around the world.
In the fourth quarter, we signed banks in APAC and the Middle East to embed our AI-enabled spreading and memo generation solutions into their loan origination platforms. We heard back from them, they're reducing decision times, in some cases, by as much as 80% and cutting loan processing cycles, in some cases, by as much as 15 times, some real efficiency.
KYC continues to deliver mid-teens growth driven by customers' trust in the quality, the governance, and the global coverage of our data. A great example is our partnership with one of the world's largest e-commerce and technology companies, where we've grown that relationship more than 20-fold over the last 3 years.
Today, our data is integrated across KYC, supplier risk, credit risk, transfer pricing, and sales workflows, and covers more than 15,000 suppliers across automated entity resolution, screening, and early warning signals. Similarly, in the fourth quarter, and there's a pattern here, one of the world's largest global payment platforms signed a multi-year, multi-million-dollar agreement to embed Orbis via API into their new customer onboarding processes.
They're threading two critical requirements. They're creating a smooth customer experience through pre-populated applications while addressing enhanced KYC due diligence requirements from their regulators.
Just to bring it up another notch, Moody's data is being used at the highest levels of the intelligence spectrum. In the fourth quarter, INTERPOL announced they're leveraging our ownership and firmographic data to support their operations targeting illicit finance, with a recent operation resulting in 83 arrests across six countries.
It's in environments like this where accuracy, provenance, and the auditability are non-negotiable. Now, our data can't be synthesized from public sources.
It reflects how ownership and control actually work in the real world, cutting through complex, multilayered structures across jurisdictions and reflecting years of proprietary data curation, entity resolution, and relationship mapping. It's that breadth and depth that makes our data both AI-enabling and AI-resilient.
We see some similar dynamics in insurance as well, where rising climate-related losses are driving demand for more data-intensive, model-driven solutions. In December, we launched our high-definition severe convective storm model that was calibrated on more than $55 billion of granular claims data.
That was contributed by the industry and available nowhere else. Then we delivered that SCS model through our cloud-based Intelligent Risk Platform.
Early adoption has been strong, reflecting the demand for more precise underwriting as these secondary perils, as they're called, increasingly behave like primary risks. We believe the common thread here is clear.
As AI proliferates, value accrues to providers of trusted context, decision-grade data and analytics that are embedded, auditable, and difficult to replicate. That is exactly where Moody's sits.
Stepping back, our confidence heading into 2026 is grounded in the durability of the business model that we've built and the discipline with which we allocate capital. We operate businesses with structurally attractive economics, complementary revenue streams, and deeply embedded customer relationships.
It's these powerful business dynamics that allow us to generate strong cash flow and invest confidently in the areas with the highest long-term returns while continuing to expand margins. On Ratings, we've continued to broaden our methodologies and deepen expertise in areas aligned with the huge global funding needs and market innovation.
That includes infrastructure and AI investment, public and private market dynamics, energy transition, and digital finance. At the same time, we're further investing in our global footprint to ensure that we are supporting the markets and issuers that will define the next phase of growth.
In Analytics, we're advancing a very deliberate strategy to position Moody's data as a trusted context layer for AI. We're accelerating efforts to link our massive data estate, expand network-based insights, and make our content more actionable within customer workflows.
Given the traction we're seeing, we've established a dedicated sales team focused on agent-ready data in 2026, and that reflects both customer demand and our conviction in this opportunity. Now, from a product standpoint, our innovation engine is highly active, with the majority of 2026 growth expected to come from three primary areas.
First, in lending and credit decisioning, we're upgrading customers onto more integrated, AI-enabled platforms. This includes moving CreditView users to what we call Moody's View, expanding CreditLens into a broader lending suite, and delivering agentic capabilities such as automated credit memos and early warning tools.
We're also expanding and packaging our credit tools specifically for private credit origination and underwriting, where demand continues to grow. Second, in KYC and compliance, we're focused on driving efficiency and scale.
For financial institutions, we're delivering productivity gains through workflow partnerships and piloting screening and diligence agents. For corporates, we're rolling out a simplified, modular compliance suite that scales in data and functionality based on a company's size, exposure, and sophistication.
All of that will be delivered through the Moody's for Compliance platform. Third, in insurance, we continue to invest across catastrophe modeling, underwriting, and risk transfer.
This includes ongoing migrations to our cloud-based Intelligent Risk Platform, new high-definition model offerings, and enhanced data management capabilities with our new Risk Data Lake. We're leveraging our geospatial artificial intelligence alongside Moody's hazard and risk scores to deliver a holistic property intelligence solution that supports underwriting decisions.
We're also expanding into casualty and financial lines by combining Praedicat's capabilities with Moody's data, where we've demonstrated strong signal value and customer interest. In the capital markets, we see an opportunity in catastrophe bonds as climate risk increasingly migrates into structured finance, an area where Moody's is uniquely positioned at the intersection of models, ratings, and market infrastructure, with the recent launch of our cat bond rating methodology and revamped cat bond modeling platform.
Across both Analytics and Ratings, a critical enabler of this growth is the continued buildout of our AI context layer and knowledge graph. We're capturing large new structured and unstructured datasets and leveraging our global connectivity to enrich how our AI systems and our analysts understand risk, relationships, and exposure.
That's not a point solution; it is a foundational capability that compounds the value of everything that we do. Taken together, this is a portfolio designed to perform across market environments.
It strengthens our competitive advantages, extends our growth runway where we have a clear right to win, and supports durable value creation for shareholders. Before I hand it over to Noémie, I want to thank our teams for their exceptional work in 2025.
Noémie, over to you.
Noémie Heuland
Thanks, Rob, and hello, everyone. The fourth quarter capped off an outstanding year across the board.
While we experienced tariff-driven uncertainty that resulted in a market-driven air pocket early in 2025, conditions recovered as the year progressed, and we finished very close to our initial internal expectations. Let me start with Moody's Analytics.
In 2025, we sharpened our focus on our highest-conviction growth opportunities while continuing to actively optimize our product portfolio and manage costs with discipline. For the full year, MA revenue grew 9%, and adjusted operating margin improved by 240 basis points to 33.1%.
This performance builds on our already strong financial profile, delivering consistent growth at scale with a very high concentration in recurring revenue and retention in the low to mid-90s. ARR reached $3.5 billion, up 8%, which is in line with organic constant-currency recurring revenue growth, also at 8%.
Now, before turning to the drivers of ARR growth, I want to do a quick reminder on the MA revenue disclosures. Reported revenue reflects period results, and that includes FX and M&A.
Organic constant-currency recurring revenue measures renewable software licenses, decision-grade data, and world-class content and analytics, which collectively represents an incredibly durable core business, and that removes FX and M&A. However, growth rates can still vary quarter to quarter due to upfront revenue recognition timing, especially for on-premise licenses.
Now, ARR is forward-looking. It's normalized for FX and M&A, and it reflects the current position of recurring contracts.
As a result, this gives, in our view, the clearest perspective of customer demand and the future revenue base. Using that lens, let me walk through a few highlights.
Starting with Decision Solutions, which includes KYC, insurance, and banking, and continues to be a key growth engine for MA. These businesses delivered double-digit ARR growth and represent approximately 45% of total MA ARR, underscoring both their scale and strategic importance.
KYC remains the fastest-growing component, with growth consistently in the mid to high teens over the past 2 years and 15% ARR growth at the end of 2025. Growth in KYC continues to be driven by both deeper penetration with existing banking customers, especially Tier 1 institutions, as well as expansion beyond our traditional financial services customer profile.
We are increasingly seeing demand from non-financial customers for unique solutions to address complex, high-stakes compliance challenges, as you heard Rob talk about with the INTERPOL example. We delivered very strong net growth in the quarter, supported by both new customer wins and continued cross-selling and expansion with existing relationships.
Now, a few recent deals illustrate the power of our solutions here and our ability to deliver trusted outcomes for customers. As Rob referenced earlier, we secured a competitive KYC displacement win at a Tier 1 bank that also leverages a broader set of Moody's solutions.
What this example illustrates is our ability to build and more broadly scale relationships over time. In fact, the relationship grew by more than 20% in '25, and continues to present meaningful expansion opportunities in '26.
Beyond the payments company customer example Rob mentioned earlier, we won new business with two manufacturing corporates, including a leading global aerospace and defense company facing new U.S. export control requirements.
In this case, the customer needed a solution capable of identifying ownership and control structures across complex global entities to comply with the BIS 50% rule and the evolving export restrictions. We are uniquely positioned to address this kind of customer challenge because of our ability to link together billions of ownership structures through our extensive network of local registry relationships.
Turning to Banking, our focus and customer mix here differ quite a bit from KYC. While KYC is anchored in deep relationships with Tier 1 banks and corporate customers, our banking offerings in Decision Solutions are much more significantly concentrated with Tier 2 and Tier 3 institutions, where demand is centered on scalable, configurable, end-to-end workflow solutions that are ready to deploy.
Banking delivered ARR growth of 8%, that's up from 7% in the third quarter. This business includes our lending suite, as well as risk, regulatory, and finance solutions.
We are actively investing in expanding our end-to-end offerings for lending, including with AI capabilities from the Numerated and Able AI acquisitions, strengthening decisioning, automation, and customer experience. In this line of business, we have been deliberately reducing transactional revenue over the last several years, primarily by expanding our partner network to serve the lower-margin implementation services for our solutions.
You'll see, in 2025, this trend continued and was compounded by the recently completed divestiture of the Learning Solutions business, which is a further sharpening of our focus within the banking portfolio towards the highest-demand and quality revenue. Now turning to Insurance, demand for our most sophisticated high-definition models and cloud-based Intelligent Risk Platform drove 7% ARR growth for the year-end '25, and that's an increase of 21% over the last 2 years.
Looking at this 2-year view is important because 2024 was particularly strong, reflecting record levels of customer migrations onto the IRP, combined with large model upgrades and new product adoption. Stepping back, our recent performance underscores the successful integration and execution of growth strategies we laid out for the RMS business following the acquisition.
In fact, we completed, and slightly exceeded, the financial target associated with that transaction, adding $150 million run-rate revenue by 2025. Now, achieving that milestone required shifting RMS from flattish growth in 2021 to a high-single-digit CAGR, including synergies, over a 4-year period.
That's a transition that was supported by sustained customer demand and meaningful platform-led upsell activity. Next, turning to Research and Insights, we achieved 8% ARR growth in this more mature business, underscoring the durability of demand, continued innovation, and improved customer retention.
As Rob shared, we are enhancing CreditView with an expanding set of Moody's content and agentic solutions that improve productivity, insight generation, and workflow integration. This reinforces its role as a core decision-support platform and driving continued adoption.
Finally, Data and Information delivered 7% ARR growth, supported by strong pricing power and sustained customer demand across two distinct but complementary areas. Ratings data feeds are the primary growth driver within the segment, with ARR growth well above the overall line of business.
That underscores their decision-grade nature and central role in customers' credit, risk, and investment workflows. In parallel, our decision-grade data estate, which includes company, ownership, people, and news, is increasingly embedded in customer workflows across a wide range of third-party risk use cases.
Now, growth in this area can vary year to year based on deal mix, including the timing of closure of renewals of large enterprise-wide data agreements versus sales to smaller institutions. As we've shared, 2025 was impacted by DOGE-related cancellations across several U.S.
government agencies. Excluding these items, underlying demand and customer engagement remain solid.
We've had several notable Orbis wins in the fourth quarter, including one with a large global bank for enterprise-wide access and a new partnership with one of the world's largest asset managers, underscoring the breadth, relevance, and durability of our data estate. Turning to margin, as I mentioned earlier, Moody's Analytics delivered ahead of the target we originally set for 2025, and that's even as we absorbed acquisition-related headwinds and continued to invest in future growth.
What differentiates Moody's Analytics is our ability to invest in growth while expanding margin. We expect to be able to sustain this balance for the years to come because beyond near-term cost actions, we're making structural changes to how roles are set up in our core processes.
Let me give you an example. We're building out a single, standard, GenAI-led product development lifecycle process across MA, which we expect will drive higher productivity, improved quality, and faster delivery for customers.
In parallel, we're embedding advanced analytics and GenAI into other core workflows, such as sales account planning, which allows us to scale impact and customer value without proportional increases in headcount. Turning to MIS, fourth-quarter revenue was up 17% year-over-year, and performance here was driven by activity that was very strong, particularly in the investment-grade asset class within corporate finance, where tight spreads, strong investor demand, and several large jumbo deals from hyperscalers supported record issuance.
Project and infrastructure finance also had near-record issuance in the quarter. Private credit across all asset classes grew 40% in Q4 from particularly strong activity in fund finance and securitization.
Transactional revenue increased 22% in Q4, supported by 10% issuance growth and a more favorable deal mix, as lower-yield bank loan repricing activity declined versus the prior-year quarter. MIS recurring revenue was particularly strong, up 9% year-over-year in Q4.
Turning to margins, MIS delivered a full-year adjusted operating margin of 63.6%, representing 350 basis points of year-over-year expansion. That reflects strong operating leverage in the Ratings business driven by continued technology investments and disciplined capital allocation.
Looking forward, we expect investment needs will continue to increase, and debt remains an attractive funding source. Accommodative monetary conditions, declining default rates, and healthy investor demand for yield should support access to capital across sectors.
For the full year 2026, we expect total issuance to increase at a low-single-digit percent pace, followed by ongoing refinancing needs and 40% to 45% increase in debt-funded M&A issuance. We also expect ongoing growth from private credit, as well as issuance from hyperscalers and AI-driven data centers.
Based on our issuance outlook, we expect MIS revenue for 2026 to grow at a high-single-digit percent pace. Our forecasts project year-over-year growth across all four quarters, strongest in the first half and moderating in the second.
We're projecting a full-year operating margin of approximately 65%, that's up 150 basis points versus 2025. For Moody's Analytics, reported revenue guidance is at the high end of mid-single-digit growth, including an 180-basis-point headwind to year-to-year growth from the divestiture of our Learning Solutions business.
Adjusting for the effect of this divestiture and even foreign exchange rates across the 2 years, we expect organic constant-currency recurring revenue growth to be aligned with ARR in the high-single-digit percent range. From a margin perspective, our 34% to 35% adjusted operating margin outlooks reflect approximately 150 basis points of improvement at the midpoint.
Putting this all together, we expect MCO revenue growth in the high-single-digit percent range and MCO adjusted operating margin likewise expanding by 150 bps to the 52% to 53% range for 2026. Our 2026 adjusted diluted EPS guidance is $16.40 to $17, implying approximately 12% growth at the midpoint.
We expect the effective tax rate to be in the range of 23% to 25% in 2026, a more normalized overall rate after we realized a sizable M&A-related one-time benefit in 2025. We've also added a new appendix slide with additional detail to provide further insights into the key drivers of our results and 2026 outlook assumptions.
Lastly, we're expecting free cash flow to be in the range of $2.8 billion to $3 billion, 13% growth at the midpoint. Now, this guide is impacted by a notable $100 million increase in CapEx for the buildout of our New York headquarters and London office space.
We expect to repurchase approximately $2 billion in shares during the year and announced a 10% increase to our quarterly dividend. Overall, our capital plan calls for a return of at least 90% of our free cash flow to shareholders in 2026.
Given the recent market activity in our sector and our strong fundamentals and durable growth outlook, you can expect us to be aggressively buying back shares at these levels. In short, both our 2025 results and our outlook for 2026 demonstrate the strength and differentiation of our financial profile and confidence in our ability to continue to deliver long-term value for shareholders.
With that, operator, we're now happy to take questions.
Operator
Thank you. If you would like to ask a question, please dial star one on your telephone keypad.
If you are on a speakerphone, please pick up your handset and make sure your mute function is turned off so that your signal reaches our equipment. We'll ask that you limit yourself to one question.
The option to rejoin the queue will be unavailable. Again, that is star one to ask a question.
Our first question comes from Curtis Nagle with Bank of America. Please go ahead.
Curtis Nagle
Terrific. Thanks so much for taking the question.
Maybe, Rob, just a quick one from you. Just from a portfolio perspective for MA, it seems like it's in pretty good place, but I guess do you feel like at this point you have the right assets, the highest growth, the ones you're feeling most confident in terms of investment, or should we expect more paring this year?
Robert Fauber
Curtis, first of all, welcome to the call. It's great to have you on today.
I would say we feel very good about the assets and the capabilities that we have. You heard me talking about this, Curtis, a bit in my prepared remarks.
I think we all understand that data and trusted data is going to be the fuel for AI, and especially for the big regulated institutions that are big customers of ours. We feel very good about having built out this massive data estate.
Then now, as you heard me talk about, it's about linking that and it's about the ability to draw insights across that network of data. Again, I think we also understand that proprietary datasets will be at premiums going forward.
Wherever we have an opportunity to add uniquely valuable data into this giant data estate, putting it into our context layer, helping to build out our network graph, I think you're going to see us do that. In terms of the trimming, you hear us talking about where we're making the more concentrated bets.
I talked about lending and credit decisioning, KYC and compliance, and insurance. Those are the places where we think we bring the strongest set of capabilities, the deepest customer relationships that give us the strongest right to win.
We felt there was just an opportunity to look across the portfolio at things that weren't as central to that, and had an opportunity to, as you said, kind of prune the portfolio and allow us to focus even more on the areas of the greatest scalable growth opportunities.
Curtis Nagle
Okay. Thank you.
Appreciate it.
Operator
Our next question comes from Alex Kramm with UBS Financial. Please go ahead.
Alex Kramm
Yes. Good morning, everyone.
Want to stay on MA. Thanks to both of you for all the AI detail, a lot of impressive stats.
On the flip side, though, it doesn't sound like it's really translating into ARR revenue yet. Maybe it is, but obviously if we look at the guidance and the results relative to your medium-term outlook, those have kind of softened a bit.
I guess the question is, when is AI really going to contribute, and if it's already contributing, are there some other issues elsewhere in the business? Maybe an open question there.
Thanks.
Robert Fauber
Hey, Alex, thanks. I think, in a way, there's kind of two parts that I want to unpack in that question.
The first is kind of your observation around the trajectory of MA. I would say that our fourth-quarter ARR was in line with the third quarter.
As you'd expect, when you've got I'm going to say kind of a portfolio, we're selling into very different customer bases, there's some puts and takes in terms of what's growing faster and what's growing not as fast. If you look at kind of the ARR trend across the portfolio in 20 2025, I think you'd see that actually Banking, Research, and Data actually picked up a little bit, and we had some headwinds with Insurance and KYC.
As you heard Noémie mention, we've talked about before on the call, some of that with KYC was impacted by DOGE. You see our guide, that's consistent with these growth rates.
I talked about the new products and the cross-sell and upgrade pathways that are going to drive that growth. I think maybe one other point I want to just double-click on, everybody wants to understand how much revenue is being generated by AI, and there were two stats that, again, I want to come back to because I do think they are leading indicators for us.
One is the fact that those largest accounts for us are growing at about twice as fast as the rest of the portfolio. That's really important because that's where we have the deepest engagement with the most sophisticated institutions on the planet.
That's where they all want to be able to consume our content and bring it into their own AI workflow orchestration platforms and consume it through AI portals. There is a lot of AI-oriented engagement with those big institutions.
That's what's, importantly, driving that growth. Then second, we have that stat about the cohort of customers who have bought at least one standalone or upgraded into an AI solution, that's growing twice as fast, again, because of the level of engagement.
I think, Alex, I feel good that the most sophisticated institutions are where we've got the most growth and the most engagement around AI. Our view is that that's going to then trickle through the rest of the customer base over time.
Alex Kramm
Very helpful. Thank you.
Operator
Our next question comes from Manav Patnaik with Barclays. Please go ahead.
Manav Patnaik
Good morning. I was just hoping on the Ratings side you could just help us with the cadence for the year in terms of how you've assumed the issuance trajectory there.
Robert Fauber
Manav, hey, great to have you on the call. I'm going to start with issuance, and then maybe I'll go into revenue real quickly for you because I know that'll be helpful.
We're expecting issuance activity, like we typically do, to be more heavily weighted towards the first half of the year. We have very attractive market conditions and, there's, I would say, a relatively strong start to the year as well.
That's also in line with what we've been hearing from the banks who we've been talking to, who think that the issuance, again, will be a little bit front-loaded in the first half of the year. To give you a sense, that's probably mid-50s percent of total issuance is going to be in the first half of the year.
At least, that's what we're modeling. That was pretty consistent with '23 and '24.
'25 was a little more back-end loaded, I think, as you know. That's also a pretty consistent pattern that we see with frequent issuers.
To put a finer point on it, Manav, we're expecting issuance to grow in the first half of '26 in the kind of high-single-digit range versus the first half of last year, and to decline mid-single-digit in the second half. In the first quarter in particular, we think we're going to see kind of high-20s percent of issuance as a percent of the full year.
Now, when we go to revenue, it's a little less pronounced in terms of being front-end loaded. I would say, from a revenue perspective, we expect it to be somewhere in the low to mid-50s percent of revenue in the first half of the year.
I think, importantly, we do expect revenue growth in each quarter of the year. We think that we're going to be somewhere in the mid-teens for revenue growth in the first half of the year, and somewhere in kind of the low-single-digit range for the second half of the year.
For the first quarter, probably somewhere in the mid-20s percent.

Our next question comes from Toni Kaplan with Morgan Stanley. Please go ahead.
Toni Kaplan
Thank you so much. I've been getting an increasing number of questions recently around how much of your data is proprietary, the sources of your data, and which parts and how much of MA is based on proprietary data.
I was just hoping that you could dimensionalize this in a way that you think is most helpful for investors. Thank you.
Robert Fauber
Toni, rather than me sitting here and trying to convince you of some statistic, let me help you think about it in slightly a different way. This is about why we think we are well-positioned in an AI world.
First, as you said, we all understand we have a massive proprietary data estate. You heard me talk about we're in the process of unifying all of that, all the data, the models, the ratings, the research, the risk assessments into really a single, normalized record for each entity.
That is going to be able to give us the ability to create a very, very powerful knowledge graph, right? We're going to keep adding to that.
That is going to enable the agents to be able to access a comprehensive, interconnected view of any entity, and as I said, give unique insights and allow for richer decision-making. The second thing, I think this is important, is we're assembling all of that into what we call, and you might have heard me use this term, a trusted context layer.
That context layer sits between the raw data assets and the AI reasoning engines. It makes the data usable for reasoning.
What that is is a structured, governed representation of what the data means, how it relates across entities in time and scenarios, when and why the data should be applied, and much, much more, right? It is a deep contextual understanding of the data.
Orbis, obviously a very important part of this massive data estate, is a great example. It's not just company data.
It's years of entity resolution, ownership mapping, expert judgment, and, of course, a complex ecosystem of licenses and IP rights. We've built all of that context directly into our analytics, our methodologies, and our models so that then the outputs are accurate, they're explainable, and they're defensible.
As you've heard me say, and I love this term, they're decision-grade. Hopefully, that gives you a sense.
It's all of that together that makes our data, I think, uniquely valuable.
Toni Kaplan
Thank you.

Our next question comes from Ashish Sabadra with RBC. Please go ahead.
Ashish Sabadra
Thanks for taking my question. I wanted to ask a follow-up question on AI.
Thanks for highlighting the AI resilience and strong demand for the agentic solution. One of the investor concerns lately have focused on adoption of white coding and verticalized LLM offerings, such as Claude for financial services, and those potentially impacting vertical software or workflow solution.
Can you talk about the moat around the software or vertical solutions within MA? Thanks.
Robert Fauber
Ashish, hey, great to have you on the call. Again, I think the way to think about this, and it's interesting if you think about, you heard me talk about CreditLens and our lending solution, and has an AI-enabled layer to all of it, from the ingestion of financials to credit decisioning and covenant monitoring and much more, you've got different adoption curves with different customer segments.
You heard me say, at the high end, almost all of the banks, the big Tier 1 sophisticated banks, want to be able to consume our content in a variety of different ways, and it's typically not through software, right? I mentioned it in my remarks.
They're building an agentic workflow for lending. While they don't need to adopt CreditLens, what they do want is they want our specialized agents around credit memo generation and early warning that are populated with all of our data and access to our models.
They're consuming it either through smart APIs and MCPs or specialized agents that are going right in to the workflow that they're building. For me, again, it comes back, we talk about we're going to be wherever our customers want us to be.
If you are a Tier 3 bank and you want a lending software platform that's enabled with AI, we're going to sell that to you. If you want our content through, as I said, different ways to consume the data or specialized agents, we'll do that.
If you want to consume it in a enterprise software system, we'll do that. In a way, Ashish, I'm actually less worried about it because at the end of the day, and we've always talked about this, the software that we have built is simply a delivery chassis for the content.
It's not just some business logic that we've sold to a customer; it's a delivery channel for the content. We'll deliver it through software, we'll deliver it into your AI platform, doesn't matter.

Our next question comes from the line of Andrew Steinerman with JPMorgan. Please go ahead.
Andrew Steinerman
Hi, I have a simple one. I just wanted to know how much of revenues these two MA divestitures affect the MA revenue guide for '26.
Then let me just add on to that. I also want to understand how they affect the MA ARR figure.
Are divestitures included or excluded when you report MA's ARR?
Noémie Heuland
Andrew, hi. Let me start with the first part of your question in terms of how those affect our guide.
Learning Solution was actually divested in December, obviously for 2025, there's a very immaterial impact. In terms of our outlook, we expect about a 1 percentage point of headwind to the MCO revenue growth, and that's reflected in our outlook for total revenue.
We expect a little under 2 percentage point headwind to the revenue growth. Sorry, 1% 1 percentage point headwind to MCO revenue growth and 2% headwind to MA revenue growth, which is embedded in our guide.
Most of it is one-time, that's about 90%. Going forward, it should modestly improve the total revenue growth on a pro forma basis that the training revenue was a slower, flattish growth, and when it rolls off, that should improve the profile going forward.
This is broadly neutral to MA, about 30 point 30 basis points on MA margin dilution, and very minimum for the MCO adjusted operating margin guide. Now, for the regulatory business, this is not yet reflected in our guide.
We expect the transaction to close around mid-year of 2026. We'll update our guidance to reflect that impact at the time.
Just to give you a sense of the impact when it closes, we expect about 2 percentage points of headwind to MA reported revenue growth, and that's mostly recurring. We expect 100 basis points tailwind of MCO adjusted expense growth, and about 10 basis points dilution on MCO margin.
This will also have a minor $0.05 to $0.10 adjusted EPS impact. It depends on when the timing of the transaction closes, as we anticipate to redeploy some of the sales proceeds to additional share buybacks.
Just on your last question about ARR and constant-currency organic recurring revenue, this is what ARR is adjusted to eliminate the effects of divestitures and acquisitions, and we expect both of those to grow high-single-digit in 2026.
Andrew Steinerman
Thank you, Noémie.

Our next question comes from Owen Lau with Clear Street. Please go ahead.
Owen Lau
Good morning. Thank you for taking my question.
I want to go back to your MIS margin guide, which is better than expected, and I think it's even higher than your medium-term guidance, which is around low 60%. Could you please talk about the driver of this strength and how should we think about your medium-term guide from here?
Thanks a lot.
Noémie Heuland
Yeah. We're guiding adjusted operating margins for Moody's Ratings of about 65%.
I think there's two components, obviously, revenue and transaction revenue growth, but we've also made significant investments, if you recall, over the past couple years or 3, 4 years on technology enablement, and around our data, and Rob talked a lot about the value of the Ratings data feeds and all the data that our analysts produce, all the insights. We've done a lot of work around that.
We've also equipped our Ratings analysts with pockets of automation tools to be more efficient and spend more time actually in rating committee, spending time with issuers, and less so on more administrative tasks. That's really driving increased operating leverage.
We're still investing in the Ratings while, at the same time, improving and getting those margins level. We're investing in analytical staff to support obviously the volume, but also areas like private credit.
We're looking to also our commercial efforts, as well as methodology groups, and technology more broadly. We're still investing in Moody's Ratings, and at the same time, expanding margin through those investments in technology.

Thanks a lot.

Our next question comes from Craig Huber with Huber Research Partners. Please go ahead.
Craig Huber
Oh, great. Thank you.
Rob, I thought you did a really good job talking about your AI moats that you have, but just a little further on that. Within Moody's Analytics, there's obviously concern out there with investors, you can see it in your stock price and in all your peers as well, that AI firms or firms that pop up or exist that have AI tools over time could replicate what you guys do in parts of your MA operation.
Can you just talk a little bit further about the moats, or where do you think, just to talk on the other side of this, where do you think maybe you are vulnerable to a third-party AI initiative that takes some share away from you on a meaningful basis? Then on the second way to look at this is, there's a lot of concern out there, people talking about that AI is going to ravage the white-collar workforces out there in the U.S., around the world.
Talk to us, if you would, about MA, how you price your product here. It's not really on a per-seat basis, but if white-collar headcount out there goes down 25% plus, just say hypothetically, at a lot of your institutions, how will that impact how you get paid, how much you get paid when contracts come up for renewal?
Not existing contracts, but when they come up for renewal, how may that impact your discussions there? Thank you.
Robert Fauber
Craig, some good stuff there. Thanks for the questions.
Let me go back to Orbis for a moment because it's one of our biggest parts of our data estate, and we get questions about this. I would say a few things in terms that make it very hard to replicate that I do not think are understood.
A lot of the data just simply isn't available to the public. We have a complex ecosystem of commercial agreements and IP rights.
That has taken us decades to build, and we're constantly curating that. Second, there's legal and regulatory issues, privacy laws and export controls and all sorts of things that our customers need to know that we're abiding by, right, if they're going to use the data.
There's semantic complexity. This gets into things in different jurisdictions mean different things, and models have a lot of challenges with semantic drift.
That's where we've been curating all this, and our local experts over decades understand what different things mean in different locations, and then they're cleansing and normalizing that data to make it valuable. There's entity resolution and ownership inference.
By the way, the models are not simply doing entity resolution. That is a really important thing, to be able to resolve against the right entity.
We've combined probabilistic models, a human-in-the-loop validation, and proprietary logic. We've been doing this over years and years and years.
Then we've got all this historical depth, right? We have a lot of historical depth, and in some cases, the data has either been archived or it doesn't exist in digital forms.
It's not easy to get some of that history. Then finally, governance.
I got to tell you, Craig, every bank I talk to tells me good enough is not good enough for our institution. What they want from us, they want to move, in many cases, to fewer trusted providers.
They want us to be able to meet their needs. Look, I'll acknowledge, Craig, that things like automated data ingestion and things like that will be done by AI.
It's those things that I talked about, and it's not just Orbis. You could go across a number of other datasets that we have, and the same is true.
Hopefully, that gives you a sense. Now let me talk about how do we price the product.
We've never had seat-based licenses. That's not the way we have operated.
We've always tried to, kind of think about value in our pricing schedules. Look, we are starting to trial, in parts of the business, different pricing models, right, and thinking about elements, bringing in elements of consumption-based pricing that I think will be more closely aligned to outcomes, right?
Because at the end of the day, Craig, what you're talking about, if there is a substantial labor replacement, somebody and some companies are going to capture some of that opportunity, maybe not all of it, but they're going to capture, right? That is going to be, in my opinion, a combination of the model providers and the data providers who are making that efficiency possible.
We are thinking as we speak and trialing different pricing models to be able to capture some of that, frankly, some of that upside.
Craig Huber
