Volume is in retail P&C tuck-ins. Strategic risk for Sompo is the handful of platform deals that rewrite who controls the submission.
Aon–USI is the distribution event of the year. Middle-market property, casualty, WC, and construction flow will concentrate.
Aspen is in the P&L. Monte Carlo is the first 1/1 cycle of the combined Sompo Re + Aspen franchise.

Risks

Producer movement at Marsh, Aon, WTW, and Howden can orphan incumbents mid-term.
Builders-risk underinsurance from 25–30% tariff-driven values.
Excess construction casualty still +5% to +30% — capacity is not a given on large wrap-ups.
Aspen integration optics versus actual authorization speed at 1/1.

Cautiously constructive. Capital is moving and Sompo’s platform is scaling, but talent litigation and construction casualty keep the tape honest. · seed brief

On the wire

Aon will buy USI Insurance Services from KKR and other shareholders for $17 billion, one of the largest insurance brokerage deals in years. Close is targeted for Q4 2026; Mike Sicard will lead Aon’s middle-market platform.

Net price about $16.7bn after $278m of tax attributes — roughly 14.5x synergized TTM adjusted EBITDA.
Aon cites $395m of annual run-rate net adjusted EBITDA from revenue and cost synergies; accretion to adjusted EPS in 2028.
Builds on Aon’s NFP purchase and doubles down on U.S. middle market versus Marsh and Gallagher.

Desk note — For Sompo this is a distribution event, not just a broker scoreboard. A combined Aon–NFP–USI middle-market machine will concentrate casualty, property, and specialty flow — and will expect panel capacity, product breadth, and claims service in return.

Open (paywall)

MarshBerry’s deal tape through June 30, 2026 lists 785 insurance-brokerage transactions, 476 of them P&C, versus 18 carrier deals. Retail still dominates (699) over specialty (112).

The buy side is still overwhelmingly brokerage, not carriers or banks.
P&C agencies remain the most acquired sleeve.
Specialty is a minority of count but a majority of strategic attention.

Desk note — Volume is in retail P&C tuck-ins. Strategic risk for Sompo is the handful of platform deals that rewrite who controls the submission.
