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.

Aon confirmed the $17 billion purchase price for USI and framed the deal as the next build-out of its U.S. middle-market franchise after NFP.

• USI brings roughly $3bn of revenue, 10,500 employees, and about 200 offices.
• Greg Case called it the greatest value-creation chance of his 20-year tenure.
• KKR exits a 2017 platform investment — a rare full-sale of a scaled PE broker.

Analyst note — Watch appointment strategy. Middle-market construction, WC, and package business is exactly the SME lane Sompo just doubled down on with Service Insurance Companies.

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.

Sompo International’s Global Reinsurance division reported $1.55 billion of revenue in Q1 FY26, up 91.8% from $810 million a year earlier, driven by the Aspen integration.

• Aspen’s $3.5bn acquisition, announced August 2025, is now showing up in reported reinsurance revenue.
• FY25 adjusted profit was $1.7bn, up 69%, with discounted combined ratio at 82.1% (from 90.6%).
• Aspen Capital Markets brought a fee platform with more than $2bn AUM at announcement.

Analyst note — The integration is no longer a slide. Monte Carlo this week is the first 1/1 cycle where counterparties will test whether Sompo Re + Aspen prices, authorizes, and services as one franchise.

The global data-center insurance market is about $11bn today and projected past $24bn by 2030. Fire drives severity — more than half of ~$800m of studied losses. Demand is stretching from builders risk into BI, power, and cyber-physical.

• Swiss Re Institute is the $11bn → $24bn source tape.
• Water damage is the frequency story; fire is the severity story.
• Integrated construction-to-operate covers at hyperscale values are still scarce.

Analyst note — New white space, not a rate story yet. Sompo’s construction, property, energy, and cyber desks will see the same submission. The question is who can authorize the whole stack.

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.

Sompo International signed a definitive agreement to buy Service Insurance Companies, a 1982-founded monoline WC specialist focused on SMEs and the general-agent channel. Terms undisclosed; close subject to regulatory approval.

• Chris Sparro: the deal creates a flagship for Sompo’s U.S. workers’ compensation franchise.
• Brad Davis stays on to run the business and extend it from monoline WC into a diversified commercial platform.
• Advisors: Guy Carpenter Capital & Advisory (Sompo) and Howden Capital Markets & Advisory (Service).

Analyst note — This is the SME / GA distribution play that sits next to Aspen’s specialty and capital-markets stack. Construction accounts and wrap-ups will feel it in 2027 renewals if the close lands.

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.

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.

Analyst 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.

PwC’s mid-year 2026 insurance deals outlook says megadeals still dominate value while private equity stays active across L&A, P&C, and distribution — increasingly via sidecars, reinsurance, cat bonds, and minority structures.

• PE demand remains strong but more selective on underwriting quality.
• Alternative asset managers want liability origination plus investment-management mandates.
• Distribution roll-ups continue even as organic broker growth cools.

Analyst note — The Aon–USI print at ~14.5x is the new comps tape for every PE-backed broker still in the market. Specialty MGAs that cannot show loss-ratio discipline will not clear that bar.

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.

Since launching Howden US in August 2025, the broker has hired an estimated 500+ staff from Marsh, Aon, WTW, Brown & Brown, and Alliant — and is defending a stack of poaching suits.

• Mike Parrish (ex-Marsh Florida) is U.S. CEO; Jim Hays is vice chairman.
• Marsh, Aon, WTW, Brown & Brown, and Alliant have all filed or defended related actions.
• Overnight raids on Brown & Brown’s legacy Hays Companies benefits operation escalated the fight in December 2025.

Analyst note — Producer movement is a placement risk. When teams walk, submissions, expirations, and incumbent relationships walk with them — including Sompo’s.

Effective tariff rates on construction goods hit a 40-year high of 25–30% in 2025, with steel and aluminum as high as 50%. Policies written on last year’s values are already underinsured.

• Deloitte’s 2026 E&C outlook is the source tape brokers are using in renewal meetings.
• Labor gaps plus material inflation push completed-value calculations through the year.
• More capacity entered builders risk, which is why non-CAT pricing loosened even as values rose.

Analyst note — Underinsurance is a claims event waiting. Sompo construction underwriters should be forcing mid-term value endorsements, not waiting for the next bound layer.

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.

2026 commercial outlooks still put auto at +8% to +15% on driver shortage, BI severity, and nuclear verdicts. Cyber is forecast −5% to +10% — the residual of a soft market meeting AI-related claims.

• Auto is a capacity and severity problem, not a pricing-cycle leftover.
• Cyber’s range straddles zero; the center of gravity is still negative.
• D&O private/nonprofit is roughly −5% to +5% — orderly, not a hard market.

Analyst note — If you need a one-line whitespace map: auto in, cyber out. Construction excess sits with auto. Public D&O sits with cyber.

Amwins’ 2026 state of the market: record capacity from carriers, MGAs, and syndicates on well-engineered risks — oversubscription is commonplace. Older locations, aging infrastructure, and environmental excess (eaten by auto claims) are the other book.

• Knowledgeable brokers are still getting rate down and terms up on clean accounts.
• Carriers are tightening deductibles and terms on older schedules.
• Environmental excess is thinner, in part because large auto claims consumed the tower.

Analyst note — Two property markets, two environmental markets. The oversupply is the clean account. The white space is age, auto, and anything that looks like a nuclear-verdict class.

AXA XL’s construction property desk called 2025 a softer turning point after years of hardening: more flexibility, more capacity, more openness to complex projects — and stricter underwriting where climate CAT is real.

• ABC estimated ~439k net new construction hires in 2025 and ~499k in 2026 if spending accelerates.
• Cost inflation in labor, materials, and supply chain is still pushing insured values up.
• 2026 outlook: steadier pricing plus proactive risk mitigation, not a race to the bottom.

Analyst note — Competitors are leaning in on complex non-CAT work. Sompo’s construction franchise, now including Aspen’s U.K. property & construction specialty, should be on those same accounts.

Sompo agreed to buy Aspen for $37.50 per share in cash — about $3.5 billion — adding specialty insurance, global reinsurance, and the Aspen Capital Markets fee platform. James Shea framed it as scale at the right point in the cycle.

• Aspen brought cyber, credit & political risk, inland marine, U.K. property & construction, and U.S. management liability.
• Capital markets platform: more than $2bn AUM; 80% of 2024 fee income from non-cat, long-tail lines.
• Expected close was 1H 2026; Q1 FY26 reinsurance revenue now shows the integration.

Analyst note — This is the deal that turned Sompo from a large international P&C writer into a scaled specialty-and-reinsurance platform. Every 1/1 meeting this month is a test of that thesis.

Effective 1 April 2025, Sompo Holdings reorganized into two global segments. James Shea, CEO of Sompo International, became CEO of Sompo P&C, folding SIH together with Japan commercial and consumer P&C.

• Mikio Okumura remains Group CEO and delegated segment P&L to the two CEOs.
• The structure was the governance wrapper for the Aspen acquisition later in 2025.
• Centers of Excellence and capital-circulation management were the stated operating model.

Analyst note — Housekeeping, but load-bearing. When a broker asks ‘who is Sompo now?’, the answer is Shea’s global P&C P&L — not a Japan-only story with an international sidecar.
