Strata Layers Chart
Layer 1: The Business Model 🏛️
The simplest way to understand AJG: they’re the matchmaker between you (or your company) and the insurance world. They don’t take on the risk of paying claims — that’s the insurer’s job. AJG finds you the best coverage, negotiates the deal, and collects a commission. Asset-light, capital-efficient, and frankly, pretty elegant.
Founded in 1927 as a one-person shop in Illinois, AJG is now the world’s third-largest insurance broker with 72,000 employees in ~130 countries. The family still runs the show — J. Patrick Gallagher Jr. has been CEO since 1995.
Three ways AJG makes money:
💰 Commissions — a % of the insurance premium (bigger premium, bigger check)
📋 Fees — flat or service-based, often used instead of commissions
🎁 Supplemental & Contingent Revenue — bonus payments from insurers based on volume, loss ratios, and efficiency. Variable and can swing quarter-to-quarter.
The three business lines:
Retail Brokerage (75% of brokerage revenue) — placing commercial P&C, health, and specialty insurance. Especially strong in 24 niche practice groups (healthcare, construction, nonprofits, aviation) that drive ~74% of retail revenue.
Gallagher Reinsurance (12%) — reinsurance brokerage, i.e., insurance for insurance companies.
Wholesale Brokerage (13%) — hard-to-place, specialty risks; over 75% of revenue here comes from other brokers’ clients.
How they measure success: Organic commission & fee growth (6% in 2025 ↘️ from 7% in 2024), Adjusted EBITDAC margin, and compensation ratios (55% for brokerage — people are the product).
Key Takeaway: AJG is a fee-and-commission intermediary that profits from insurance complexity without ever holding the bag on claims — a beautiful business model if you can build the relationships.
Layer 2: Category Position 🏆
AJG sits at #3 globally behind Marsh McLennan and Aon — the two giants that have duked it out for decades. But AJG has been closing the gap through acquisitions (780 since 2002 — yes, seven hundred and eighty).
The competitive landscape:
MMC and AON dominate large multinational accounts; AJG has historically been stronger in the middle market
The 2025 acquisitions of AssuredPartners ($13.8B 😳) and Woodruff Sawyer ($1.2B) dramatically expanded AJG’s U.S. footprint and moved it upmarket
Private equity-backed brokers are consolidating aggressively, making targets pricier
InsurTech and direct-to-consumer models nibble at the edges, but complex commercial insurance still needs human expertise
AJG’s moat is real: Top 10 clients represent only 3% of revenue — extraordinary diversification. No single client can hold them hostage. Combine that with 24 specialized practice groups and a culture-first acquisition strategy, and switching costs are baked in.
The company trades at a discount to MMC (~22-24x EV/EBITDA) and AON (~20-22x), currently implying ~17.8x — despite comparable or better organic growth. The market is charging an “integration risk tax” on the AssuredPartners deal. Fair? Maybe. Permanent? Probably not.
Key Takeaway: AJG is the hungry #3 with a proven acquisition engine — trading at a discount to peers while executing a strategy that could close that gap.
Layer 3: Show Me The Money! 📈
Revenue breakdown (2025):
Brokerage: $12.2B (87%) ↗️ +23% YoY
Risk Management: $1.6B (13%) ↗️ +9% YoY
Geography: 67% U.S., 33% international (UK, Australia, Canada, NZ)
Revenue composition (Brokerage):
Commissions: $8.0B ↗️
Fees: $2.6B ↗️
Supplemental & Contingent: $790M ↗️
Interest & Other: $732M (includes $363M from sitting on AssuredPartners deal proceeds — a one-time boost)
Organic growth was 6% in 2025 — solid, but the headline 23% revenue growth is almost entirely M&A-driven. Don’t confuse the two.
Margins: Adjusted EBITDAC margin expanded to 36.5% ↗️ (+145 bps) for brokerage. Compensation runs at ~55% of brokerage revenue — this is a people business, full stop. Encouragingly, that ratio is improving as scale kicks in.
The debt situation: AJG took on ~$13.1B in total debt to fund AssuredPartners. Interest expense jumped to $639M in 2025 ↗️ from $381M in 2024 — the price of playing big. Operating cash flow dipped to $1.93B ↘️ (from $2.58B), partly due to a $750M earnout on the old Willis Re deal. Normalized FCF is closer to $2.5B+; the reported number is distorted by acquisition activity.
Goodwill: $22.6B on the balance sheet (32% of total assets) — a lot of faith in future cash flows. Not impaired, but worth watching.
Key Takeaway: The underlying business is healthy and growing, but 2025 financials are noisy — strip out M&A distortions and you see a ~18-19% FCF margin business with expanding operating leverage.
Layer 4: Long-Term Valuation (DCF Model) 💰
The Verdict: Moderately Undervalued 📉➡️📈
Scenario | Fair Value | vs. Current Price (~$248) |
|---|---|---|
Conservative | $290 | +14.5% |
Balanced (Base Case) | $349 | +37.4% |
Optimistic | $467 | +84.3% |
FMP Model Estimate | $329 | +29.7% |
Key assumptions:
Revenue growth of 10-12% in 2026 (full-year AssuredPartners + 6% organic), decelerating to ~6.5% by 2030
EBIT margins expanding from ~19.5% to ~22.5% as integration synergies materialize
WACC of 7.2% — AJG’s low beta (0.51) and recurring revenue justify a low discount rate
One-line take: At ~$248, the market is pricing in the most pessimistic plausible scenario — buy if you believe AJG can integrate AssuredPartners without fumbling the ball.
Layer 5: What Do We Have to Believe? 📚
Bull Case 🚀
AssuredPartners’ 10,900 employees embrace the “Gallagher Way” culture and client attrition stays minimal
Adjusted EBITDAC margins expand toward 35%+ as $575M in integration costs wind down over 3 years
AJG keeps its M&A machine running at reasonable multiples, compounding revenue at 8-10% annually
Bear Case 🐻
Integration stumbles — cultural mismatch, key producer departures, or client losses erode the $3.5B acquired revenue base
Insurance market softens materially, compressing organic growth below 4% and squeezing contingent revenues
$22.6B goodwill pile becomes a problem if acquired businesses underperform, triggering impairments
The Bottom Line: AJG is a genuinely high-quality business with a 98-year track record, a defensible moat, and a management team that has done this acquisition dance 780 times. AssuredPartners is the biggest bet in company history, and near-term FCF looks ugly because of it. But the normalized earnings power of the combined entity is significantly higher than current prices imply. This is a “show me” story for 2026-2027.
Layer 6: What to Watch 👀
AssuredPartners organic retention — Client attrition above normal levels in 2026 is a red flag. Watch retention commentary on earnings calls.
Adjusted EBITDAC margin trajectory — Management guided toward expansion. If brokerage margins stall below 36% into 2027, the integration thesis is in trouble.
Organic commission & fee growth — 6% in 2025 ↘️ from 7%. Below 5% signals market softening or competitive pressure; below 4% is a problem.
Debt paydown pace — With $13.1B in debt and $639M in annual interest, watch FCF conversion improve and leverage decline. AJG needs to delever while still doing bolt-on deals.
Insurance market pricing — CIAB survey data each quarter. Rate increases decelerated in 2025 (4.2% → 3.7% → 1.6%). A soft market would pressure organic growth and contingent revenues simultaneously.
