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.

Analyst 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.

The 68th Rendez-Vous de Septembre runs 5–9 September 2026 at the Fairmont Monte-Carlo — the largest gathering in (re)insurance ahead of January 1 renewals.

• Welcome desk opens 2:30 p.m. Saturday, 5 September.
• AM Best’s reinsurance briefing is Sunday 6 September, 10:15–11:45 CEST at the Hermitage.
• This is the first Monte Carlo where Sompo counterparties will underwrite the combined Sompo + Aspen franchise in person.

Analyst note — Go to Monte Carlo with a one-page on Aspen integration, Service Insurance, construction appetite, and 1/1 casualty retro. The room will ask.

Gallagher Re bundled AI liability, data-center, cyber, and digital risk engineering into a single practice as brokers industrialize tech-risk placement.

• The practice sits inside Gallagher Re, not only retail — treaty and facultative clients are in scope.
• Data-center property and AI liability are colliding with traditional CAT and casualty panels.
• Follows Gallagher’s AssuredPartners digestion and its climb to the world’s third-largest broker.

Analyst note — Sompo’s specialty and Aspen cyber / management-liability capabilities need a clear answer when Gallagher Re shops these risks in the fall.

IMA’s Q2 2026 tape: commercial property led the decline at −5.5% as three-quarters of carriers added capacity. Cyber −3.5%. D&O −2.1%, the eighth consecutive down quarter. Workers’ compensation also printed decreases.

• Property loss ratio improved to 85% YE 2025 even after California wildfires and SCS.
• Cyber threat activity is intensifying — identity-based attacks, BEC, third-party — while rates still fall.
• Excess D&O capacity remains abundant; buyers are expanding limits.

Analyst note — This is the oversupply map. Non-CAT property, cyber, and public D&O are crowded. The money is in the classes that did not get this capital: auto, excess construction casualty, older property.

Mid-2026 agency-and-broker multiple observations put PE-backed platforms at $50m+ revenue at 12–16x adjusted EBITDA on primary deals and 14–18x on continuation or secondary recaps.

• Aon’s NFP print (~14x) remains the public anchor.
• Acrisure and Hub recaps in 2023–24 set the upper recap band.
• Aon–USI at ~14.5x synergized EBITDA now refreshes the 2026 tape.

Analyst note — Sponsors can still exit. That keeps roll-up dry powder in the market and keeps independent construction and casualty producers in play for Howden, Gallagher, and the remaining PE platforms.

Deloitte’s 2026 insurance M&A outlook flags specialty property and casualty, excess and surplus, and managing general agents as the P&C sleeves still drawing private capital — with brokerage M&A shifting from land-grab to digestion.

• Underwriting flexibility and fee-based MGA economics remain the pitch.
• Broker buyers are integrating, simplifying, and doing tuck-ins rather than new platforms.
• Selectivity on underwriting quality is the gating item, not dry powder.

Analyst note — Sompo does not need to outbid PE for MGAs. It needs to be the capacity those MGAs cannot replace — especially in construction casualty and specialty property.

Ground-up non-CAT builders risk is stable to softening (−5% to +10%). Primary OCIP/CCIP is orderly; umbrella and excess liability still prints +5% to +30% depending on account and attachment.

• Gallagher has reported single-layer builders-risk decreases of 5–7% in non-CAT zones.
• Inland marine stays competitive even for contractors with some adverse loss history.
• CAT-exposed and high-hazard projects do not get the same relief.

Analyst note — Sompo can be relevant on non-CAT builders risk and wrap primary. The money — and the differentiation — is still in excess casualty, delay-in-start, and CAT-adjacent project property.

CRC’s 2026 casualty note calls the E&S casualty market fragmented, not uniformly hard. Softening property has released capital into casualty, but excess auto keeps contracting and HNOA stays difficult.

• Overall casualty capacity is ample; deployment is uneven by class and account.
• Excess auto is still a layered, shrinking market.
• Strong casualty results are attracting investor interest — not uniformly into the painful classes.

Analyst note — Whitespace is not ‘casualty.’ It is auto, low-attach construction excess, and nuclear-verdict venues. Everything else is starting to see the property-capital overflow.
