AJG Arthur J. Gallagher & Co.
A high-quality, asset-light broker whose goodwill-heavy book hides its real returns; the price assumes flawless roll-up execution.
The story
AJG is a top-three global insurance broker: it earns fees and commissions without underwriting risk, has sticky renewals, and adds 5-8% organic growth plus a steady stream of tuck-in acquisitions. Trailing ROE of 6.7% is temporarily low because roughly $8.5B of equity raised for the AssuredPartners deal was on the balance sheet before its earnings arrived. GAAP book is mostly acquired goodwill and intangibles, so tangible equity is thin or negative and book ROE understates the economic return. The softening property and casualty pricing cycle is a headwind, but brokers are far less cyclical than carriers.
A 14% normalized ROE assumes AssuredPartners is fully integrated and adjusted earnings reach about $3.3B on a goodwill-heavy book of roughly $24B, consistent with AJG's pre-deal 11-14% range. Book grows about 8% in year 1 from retained earnings and acquisition-funded issuance, then fades to 4.5%, below the risk-free rate. Beta of 0.85 sits just under the industry anchor because broker revenue is fee-based and recurring.

Key risks
- Softening P&C rates slow commission growth and organic growth falls toward 3-4%
- Integration problems or overpaying on AssuredPartners and future roll-ups, raising the risk of goodwill impairment
- The market's roughly 2.5x book multiple already prices in years of acquisition compounding, so any slowdown in M&A or a fall in fiduciary investment income from rate cuts would hit the shares
Catalysts
- AssuredPartners synergies and margin expansion showing up in 2026-27 adjusted EPS
- Earnings recovering into the raised equity base, lifting reported ROE back to the low-to-mid teens
