Public Insurance Broker Performance Trends and the Impact on M&A – IA Magazine

Watching publicly traded insurance brokers is a little like watching the scoreboard during a playoff game: it does not tell you everything, but it tells you what the crowd, the coaches, and the people with money on the line think is happening. That is why public insurance broker performance matters so much to agency owners, private equity firms, and would-be sellers. The listed brokers publish results every quarter, the market prices those results in real time, and suddenly the whole industry has a fast-moving report card.

That report card got more interesting in 2025. Public broker performance, as tracked and discussed across the industry, shifted from early-year enthusiasm to a much more selective mood by midyear. The basic message was not that insurance brokerage stopped being attractive. Far from it. The message was that investors began separating sturdy, repeatable growth from growth that had been flattered by pricing momentum. In other words, Wall Street did not leave the insurance party. It just stopped dancing with every guest in the room.[1]

For dealmakers, that distinction matters. Public valuations influence private valuations, even if they do not dictate them perfectly. When listed brokers trade at premium multiples, sellers feel confident, buyers stretch a bit, and acquisition pipelines move with swagger. When those multiples compress, everyone still talks about “strategic fit,” but the spreadsheet starts getting invited to more meetings. That is exactly why the relationship between public broker performance and mergers and acquisitions deserves a closer look.

Why Public Brokers Matter So Much to the Broader Brokerage Market

The public broker universe is small, but it punches absurdly far above its weight. These firms are large, diversified, acquisitive, and heavily followed by investors. They also sit at the center of many of the trends shaping the rest of the market: specialty expansion, employee benefits growth, wholesale distribution, data and analytics investment, and the relentless search for better margins and better organic growth.

Scale alone explains part of their influence. Business Insurance’s 2025 ranking of the largest brokers, based on 2024 U.S. brokerage revenue, placed Marsh McLennan first, Aon second, Arthur J. Gallagher third, Willis Towers Watson fourth, and Brown & Brown sixth. The same ranking also showed how far the consolidation wave has already traveled: The Baldwin Group ranked 15th, CAC Group 35th, and Newfront 37th before some of the latest headline transactions were even completed.[5]

These companies act as a pricing signal for the rest of the industry. If investors reward firms with stronger specialty exposure, cleaner integration stories, and more dependable organic growth, private buyers tend to follow the same logic. If investors penalize rate-driven growth or weaker margins, private buyers suddenly become much more interested in quality of revenue, producer productivity, and client retention. The stock market may not value every private agency directly, but it absolutely influences the mood music.

The 2025 Performance Story: Growth Stayed Good, but the Market Got Pickier

The large incumbents still put up impressive numbers

The industry’s biggest public brokers continued to grow, which is why the “doom and gloom” version of this story does not hold up. Marsh McLennan reported third-quarter 2025 revenue growth of 11%, with 4% underlying growth. Aon reported full-year 2025 revenue growth of 9%, including 6% organic growth, while commercial risk solutions posted 6% organic growth and reinsurance solutions posted 8%. Arthur J. Gallagher finished 2025 with 21% revenue growth, 6% organic growth, and 33 mergers representing more than $3.5 billion in estimated annualized revenue. None of that sounds like an industry in retreat.[2]

And yet investors clearly started asking a tougher question: What kind of growth is this? Is it broad-based and sustainable? Is it heavily dependent on pricing? Is it acquisition-led? Does it come from stronger specialties, better retention, or simply a market that had been doing some of the heavy lifting? Once that question took center stage, public valuations started behaving differently.

The middle of the pack showed why nuance matters

Brown & Brown offered a great example of why top-line growth alone is not enough to tell the story. The company reported 2025 total revenue growth of 22.8%, but full-year organic revenue growth was 2.8%, and fourth-quarter organic revenue actually declined 2.8%. Ryan Specialty showed another side of the same story: third-quarter 2025 revenue rose 25% with organic growth of 15%, but fourth-quarter organic growth slowed to 6.6%. WTW’s Risk & Broking business remained solid, with third-quarter 2025 revenue up 7% and organic growth up 6%, yet the market still looked carefully at mix, margin, and strategic direction.[3]

That is the key trend. Investors were not punishing growth. They were grading the quality of growth more harshly. Wholesale and specialty businesses still looked attractive. Reinsurance and complex advisory work still looked attractive. Strong retention still looked attractive. But simple reliance on a hard market to inflate premiums? That looked less magical once pricing began to soften in parts of property and casualty.

The newer public names reinforced the same lesson

The newer or faster-growth public names also helped clarify what the market wanted. The Baldwin Group reported full-year 2025 revenue growth of 8% and organic growth of 7%. Goosehead reported 16% growth in both total revenue and core revenue for full-year 2025. Those figures showed that investors still had an appetite for businesses with a visible growth runway, differentiated models, and a strong operating narrative. Meanwhile, Houlihan Lokey’s insurance distribution market update showed just how strongly the market distinguished between scaled brokers and high-growth brokers in valuation terms during 2025. In plain English: if you could still grow cleanly, investors were willing to notice.[4]

Why Public Valuations Cooled Even Though Fundamentals Stayed Respectable

The best explanation is not that insurance brokerage became weak. It is that expectations had become very strong. When public broker stocks rise for years, the market begins assuming that mid- to high-single-digit organic growth, margin improvement, acquisition capacity, and premium valuations are all part of the natural order of the universe. Then one or two of those variables soften and investors act as if gravity has been invented overnight.

IA Magazine’s late-2025 analysis captured that pivot well. Public brokers excluding Goosehead averaged 6.7% organic growth in the second quarter of 2025, down from 9.4% a year earlier. The same analysis said public broker valuations peaked around 19.3x last-12-month EBITDA at the end of the first quarter of 2025 before dropping sharply, reaching 16.4x by September. The reason most often cited was slower organic growth tied in part to softening property & casualty pricing, especially in areas more exposed to large accounts and professional lines.[1]

That compression still left valuations historically healthy, but it changed behavior. It also fit a broader market reality. Houlihan Lokey noted that the brokerage sector’s fundamentals remained strong heading into 2025 even after prior multiple retrenchment tied to higher interest rates. Moody’s also pointed to a constructive baseline for major brokers, expecting mid-single-digit organic growth and gradual margin expansion. So the issue was not collapse. It was normalization, plus a much brighter spotlight on execution.[4][8]

Think of it this way: in a hard market, a lot of brokers can look like heroes. In a softer market, the market starts asking who can still sell, retain, cross-sell, recruit, integrate, and defend margins without the premium environment doing them a favor. That is when valuation gaps widen.

What This Means for M&A: Less Frenzy, More Selective Aggression

If you expected lower public valuations to kill insurance brokerage M&A, the market politely disagreed. Deal activity slowed, yes, but appetite clearly remained alive. Business Insurance reported 695 announced intermediary deals in 2025, down 12% from the prior year, with private-equity-backed buyers still accounting for 73% of all deals. That is not a market in hibernation. That is a market that still wants to buy, but wants to buy more carefully.[6]

Just look at the size of the transactions and capital raises still getting done. Marsh McLennan agreed to acquire McGriff for $7.75 billion. Hub International raised nearly $1.6 billion in a funding round that valued the firm at $29 billion. WTW agreed to acquire Newfront for up to $1.3 billion. Baldwin struck a roughly $1.03 billion cash-and-stock deal for CAC Group. Those are not the moves of an industry short on confidence, capital, or ambition.[7]

The more accurate conclusion is that M&A is becoming more selective and more strategic. Buyers increasingly want acquisitions that improve organic growth, deepen specialty expertise, add strong middle-market positions, expand employee benefits, strengthen MGA or wholesale capabilities, or provide real technology advantages. They are less interested in simply buying undifferentiated revenue and hoping the market bails them out later.

This is why public broker performance matters so much. When listed buyers trade well, they have stronger currency, better confidence, and more freedom to pursue larger or more numerous acquisitions. When they trade less favorably, they do not stop buying, but they usually raise the bar. Integration discipline gets tighter. Synergy assumptions get more sober. Earn-outs start doing more work. Diligence goes from “Tell us the headline growth number” to “Walk us through retention, producer economics, line-of-business mix, and monthly new business trends, and please do not skip the awkward parts.”

What Buyers and Sellers Should Be Watching Now

1. Organic growth quality

In this market, organic growth is not just a nice metric. It is the metric that helps separate lasting franchise value from temporary market lift. Buyers want to know whether growth is coming from producer talent, cross-selling, improved account rounding, niche expertise, and strong retention. If the answer is yes, valuation support is much easier to defend.

2. Business mix

Specialty, wholesale, MGA, reinsurance, construction, cyber, and complex employee benefits all tend to attract attention because they offer stronger margins or more durable demand. Commodity-like books, by contrast, are more vulnerable when pricing moderates and clients become more cost-conscious.

3. Margin durability

Revenue growth still matters, but buyers are increasingly interested in how efficiently that growth converts into EBITDA and cash flow. A firm that can grow while controlling service costs, investing in technology, and keeping producer economics sensible usually looks a lot more attractive than one that grows loudly and earns quietly.

4. Integration readiness

The acquirers likely to win the next phase of the market are the ones that can integrate people, technology, carriers, compensation structures, and client relationships without turning every acquisition into a three-year group project with emergency snacks. Scale is helpful, but integration muscle matters more than a slide deck full of buzzwords.

What the Market Has Been Experiencing on the Ground

Across the brokerage market, the lived experience behind these trends has been pretty consistent. A year or two ago, many firms could point to strong revenue growth and assume buyers would give them full credit for it. Today, buyers still like growth, but they are spending much more time asking where it came from and whether it is repeatable. That change has been felt in management meetings, banker pitches, valuation discussions, and seller expectations.

One common experience is recalibration. Owners who built their expectations during the most aggressive part of the consolidation cycle sometimes still think buyers will pay peak multiples for average businesses. Buyers, meanwhile, are walking in with sharper questions and less appetite for fairy tales. If an agency says it grew 12%, buyers now want to know how much came from exposure growth, rate, new business, retention, cross-sell, and acquisitions. If a seller cannot explain that cleanly, the room tends to get quiet in a hurry.

Another common experience is that specialty strength is carrying more weight than ever. Firms with differentiated expertise in construction, transportation, cyber, benefits, delegated authority, or wholesale distribution often get more attention because buyers view those capabilities as engines for both growth and margin resilience. Generalist books can still sell well, especially if retention and local relationships are excellent, but they usually need a clearer story than “we’re nice people and the revenue line goes up.” Nice people matter. So does math.

Operators are also experiencing a more disciplined approach to integration. During the fastest years of consolidation, some buyers seemed willing to believe every acquisition would seamlessly cross-sell, retain producers, expand margins, and make coffee. The market is more realistic now. Buyers increasingly care about cultural fit, service models, compensation alignment, and the practical ability to migrate systems without annoying employees and clients. In other words, post-close execution has graduated from afterthought to main character.

There is also a noticeable shift in how leadership teams talk about talent. Growth is no longer assumed to be a market gift. It has to be produced. That means producer recruiting, producer development, service efficiency, and client-facing specialization are back at center stage. In a softer pricing environment, the brokers that keep winning are typically the ones that still know how to sell, not just the ones that got lucky with market conditions.

Finally, there is a growing recognition that M&A has not become weaker so much as more demanding. Capital is still there. Strategic buyers are still active. Large deals are still happening. But the market now rewards firms that can prove their growth is durable, their margins are defendable, and their acquisition story actually creates value after the press release. That is a healthier market, even if it is slightly less flattering to anyone hoping to sell a decent business at a superhero valuation.

Conclusion

Public insurance broker performance trends are still one of the best real-time indicators for the health of the brokerage sector and the direction of M&A. The lesson from the last year is not that the industry lost its appeal. It is that investors and buyers became more selective. Revenue growth still matters. Acquisitions still matter. Scale still matters. But organic growth quality, specialty mix, margin durability, and integration credibility matter more.

That is likely to define the next chapter of insurance brokerage consolidation. Buyers will keep buying. Sellers will still have opportunities. Premium valuations will still exist. But the best outcomes will go to firms that can show they are not simply riding the market. They are building businesses that can grow when conditions are easy, when conditions are harder, and when Wall Street starts acting like your toughest underwriter.
