USI Insurance Services

The 1994 roll-up that Bernard Mizel built and three PE giants passed down the line — Goldman to Onex to KKR/CDPQ at $4.3B in 2017 — now a $2.78B-revenue middle-market broker betting on a proprietary knowledge engine while faster-moving rivals shove it out of the top ten.

at risk

USI's franchise is profitable and sticky, but it is losing the scale race that defines this industry — out-organic-grown and out-acquired by Hub, Gallagher, AssuredPartners and Acrisure, carrying 7x leverage with ~2x coverage, and defending its producer bench with lawsuits while rivals convert to public currency.

Snapshot

USI Insurance Services is a Valhalla, New York-based middle-market insurance brokerage — commercial property & casualty, employee benefits, personal risk and retirement consulting for mid-sized American businesses. It booked $2.78B of revenue in 2024 (up 5.1%), employs 10,000-plus professionals across 200-plus US offices, and has been owned by KKR and CDPQ since a $4.3B buyout in 2017 (Business Insurance, 2025; company disclosures). It matters now because the PE-backed broker cohort is heading for the exits: Hub International filed confidentially for a US IPO in June 2026 and Acrisure has flagged a listing at a $32B-plus valuation, which puts a public spotlight — and a public comp set — on the one big platform that has gone quiet. In 2024 USI fell out of the Business Insurance top 10 for the first time in more than a decade, overtaken by AssuredPartners, and closed exactly one acquisition all year.

Founding story

USI is one of the original insurance roll-ups. Bernard H. Mizel founded it in 1994 with a single office, roughly 40 associates and $6.5M of revenue, and ran the aggregation playbook a decade before private equity industrialized it: more than 90 agency acquisitions in the first five years, a financial-services investor consortium recapitalizing the company in 1998 (Business Insurance, 1998). Mizel retired in January 2002; his successor David Eslick took USI public on Nasdaq that October — 9 million shares at $10.

The public interlude lasted barely four years. In January 2007, GS Capital Partners, Goldman Sachs’ PE arm, took USI private for roughly $1.4B including debt. Goldman’s real contribution was the CEO: in November 2007 it installed Mike Sicard, a Duke- and Harvard Law-trained ex-McKinsey engagement manager who had been COO of Willis North America at 27 and then spent four years teaching at Vanderbilt. Sicard is the rare broker CEO who never carried a book of business — a consultant’s consultant — and he rebuilt USI around process and shared knowledge rather than star producers, the philosophy that became the ONE Advantage. The ownership relay continued: Onex bought USI from Goldman in December 2012 for ~$2.3B ($702M of equity, the rest debt), then flipped it to KKR and CDPQ in 2017 for ~$4.3B including debt — roughly a doubling in under five years. KKR has since consolidated control, injecting over $1B of new equity in September 2023 to become the largest shareholder (buying out more than half of CDPQ’s stake), and topping up again in early 2025 with Chubb co-investing alongside.

How it works

A brokerage takes no underwriting risk: USI’s producers assess a client’s exposures, shop them across carriers, negotiate terms, place the policy and service it through renewals and claims, earning a slice of premium for the trouble. Retention is high because switching brokers is painful and relationships are personal — the book behaves like an annuity that reprices with the commercial rate cycle.

USI’s twist is the ONE Advantage, its answer to the question “why should a mid-market CFO pick the No. 11 broker?” ONE stands for OMNI, Network, Enterprise. OMNI is a proprietary knowledge engine, built in-house, that codifies what USI says is the experience of 500,000-plus clients and 150-plus years of acquired-agency history into a searchable library of risk and benefits solutions by industry, size and geography (company materials; CDPQ profile). A producer preparing for a manufacturing prospect pulls OMNI’s catalogued solutions — captive structures, mod-factor fixes, pharmacy-carve-out savings — quantifies each in dollars, and presents them through the “Enterprise” planning process, backed by national specialty resources a local agency can’t match. The 3D analytics tool runs up to 36 months of a client’s claims data to locate cost drivers in benefits plans. In July 2024 USI layered AI on top, launching Ask V, an OMNI-powered platform generating vertical-specific insight across 20-plus industries (GlobeNewswire, July 2024). The pitch is systematized expertise instead of hero producers — which is also why USI polices departing producers so aggressively: the firm’s position is that the book belongs to the system, not the individual.

Product and business overview

Commercial P&C. The core: property, casualty, workers’ comp, umbrella and specialty lines for mid-market businesses, sold through regional offices with national practice support.

Employee benefits. Group medical, life, disability and voluntary benefits consulting — the segment where OMNI’s claims analytics bite hardest, and a steadier fee stream than rate-cyclical P&C.

Personal risk. Home, auto and high-net-worth personal lines, typically attached to commercial relationships.

Retirement consulting. USI Consulting Group runs defined-contribution and defined-benefit plan advisory and administration — a differentiator most mid-market brokers lack.

Programs and specialty. Vertical programs (construction, healthcare, transportation, public entities) and affinity business layered over the retail footprint.

Business model and pricing

Revenue is booked three ways. Base commissions — typically 5-20% of P&C premium depending on line — earned at binding and renewal. Contingent commissions from carriers for profitable or high-volume books, high-margin but cyclical. And fees, negotiated on larger benefits and retirement accounts. USI does not publish price cards; mid-market placements are commission-default.

The economics are classic broker: asset-light, recurring, high-margin — and, in USI’s case, heavily levered. Moody’s put pro forma debt-to-EBITDA slightly above 7x in late 2024, with interest coverage around 2x and free-cash-flow-to-debt in the low-to-mid single digits, expecting leverage to ease below 7x through EBITDA growth (Moody’s, 2024). S&P rates the first-lien term loans B; a 2024 repricing to SOFR+325 shaved 50bps (S&P, 2024). Compare Hub: similar ~7x leverage but 2.5-3.0x coverage on S&P’s numbers — USI runs the same machine with less cushion. Debt service is the quiet reason the acquisition engine slowed.

Traction over time

The arc is real — roughly 2.7x revenue under KKR/CDPQ ownership (2016-2024) — but the trajectory has flattened exactly when rivals accelerated. USI did 18 deals across 2021-2023, then one in 2024, versus Hub’s 61 and Gallagher’s rolling tuck-in machine (MarshBerry, 2025). Headcount growth slowed to ~1-2% a year by 2023-24 (Revelio Labs). Meanwhile AssuredPartners grew 13% in 2024 to $2.81B and took USI’s top-10 slot. Growth of 5.1% in a year when commercial rates were still rising and peers printed 7-13% implies organic performance at the low end of the big-broker pack.

Market analysis

US insurance distribution is a huge market consolidating fast. Global brokerage revenue estimates cluster around $315-340B for 2024-25, with forecasts toward $700B+ by 2033-34 at ~8-9% CAGR (Grand View, Precedence, 2025); North America is ~35% of it. The middle market — USI’s entire franchise — is the contested zone: thousands of founder-owned agencies with succession problems, being absorbed at 750-800 deals a year (MarshBerry, 2025). The buyer pool is itself consolidating: unique buyers fell from 140 in 2020 to 99 in H1 2025, and the ten most active buyers took 54% of deals. Average multiples hit 11.8x EBITDA in H1 2025, with platforms in the high teens (Sica Fletcher, CT Acquisitions, 2025). The structural read for USI cuts both ways: rising premiums and complexity lift every broker’s book, but in a scale game where the top ten are eating the market, standing still is losing share — and in 2024 USI, nearly alone among the majors, effectively stood still.

Competitive intel

The battlefield is the frontmatter competitor set; the summary is uncomfortable. Hub (~$4.8B revenue, $29B mark, IPO filed) and Acrisure ($4.3-4.6B, $32B mark) run USI’s playbook bigger and faster. Gallagher bought AssuredPartners — the firm that just displaced USI from the top ten — for ~$13.5B, giving a public acquirer a $2.8B middle-market platform overnight. Marsh McLennan Agency outbids everyone for premium agencies. Alliant doesn’t buy agencies at all; it lifts producer teams, converting USI’s restrictive covenants into court dates. Brown & Brown’s ~$9.8B Accession deal (2025) shows even disciplined buyers paying up, raising the price of restarting USI’s deal engine. USI’s genuine edges: the OMNI/Ask V knowledge platform is a real, decade-deep asset none of the roll-ups replicated; retirement consulting broadens the relationship; and employee ownership plus KKR’s patient core-strategy capital means no forced exit. But every rival now has either a public currency, a bigger platform, or a faster machine.

What people say

The case for. Employees rate USI 4.2/5 on Glassdoor across 2,300+ reviews, with 84% willing to recommend it — genuinely strong for a PE-owned broker, and better than most consolidators. Recurring praise: real training and national resources for producers, the Fortune Best Workplaces certifications USI touts (2024), and broad employee equity ownership since 2017, which management credits for retention. The sophisticated bull case comes from the capital: KKR has now added over $1B twice without exiting, holding USI in its long-duration core strategy, and Chubb — the largest US commercial insurer, which sees broker economics from the carrier side — chose to buy in alongside in 2025. Moody’s noted 14% revenue growth through nine months of 2023. CDPQ’s own profile praises the OMNI model as a structurally different way to sell insurance.

The complaints. Glassdoor’s negative threads are consistent: bottom-of-band pay for account managers, 1-2% annual raises eaten by benefit-cost increases, “churn and burn” over-hiring of producers, and an HR function reviewers describe as protecting management. The sharpest theme is the two-year non-compete/non-solicit regime — USI is among the industry’s most litigious enforcers, suing departing producers repeatedly (Baggett/Boxwood 2022, Fowler 2025, MacNair May 2026) and countersuing Lockton to a $3M verdict in 2024 (Business Insurance, Law360, Insurance Journal). Producers read that as a firm that retains by contract rather than by proposition. On the numbers, the critique writes itself: 5.1% growth in 2024 against AssuredPartners’ 13% and Hub’s 7.3% organic; one acquisition in a record consolidation year; leverage above 7x with ~2x coverage (Moody’s, 2024); and no external valuation mark in nine years while every major peer has printed one.

Outlook: well positioned or at risk?

At-risk — not because USI is a bad business, but because it is a good business losing a scale race in an industry where scale is the moat. Every structural advantage in brokerage — carrier leverage, contingent-commission volume, specialty depth, data — now accrues to whoever consolidates fastest, and the 2024 scoreboard is unambiguous: USI grew 5.1% while AssuredPartners grew 13% and took its top-10 ranking, Hub compounded 7.3% organically on top of 61 acquisitions, and Acrisure reached a $32B mark. USI closed one deal. The reason is the balance sheet: 7x-plus leverage with roughly 2x interest coverage (Moody’s, 2024) leaves little room to pay H1-2025’s 11.8x average multiples, so the machine that built USI has stalled precisely when targets are being permanently absorbed by rivals. Meanwhile Hub’s IPO filing and Acrisure’s raise give competitors cheaper capital and a liquid currency for deals and producer equity; USI, with no disclosed mark since $4.3B in 2017, has neither — and its talent defense increasingly runs through courtrooms, a tell that the producer proposition is under pressure from Alliant-style raiders.

The counter-case deserves respect. OMNI/Ask V is a real, hard-to-replicate operating asset; margins and retention are healthy; KKR’s core-strategy capital is patient by design and has doubled down twice; Chubb’s 2025 co-investment is informed money. If KKR recapitalizes the balance sheet — or takes USI public into a receptive 2026-27 broker-IPO window behind Hub — the deal engine could restart and the verdict flips. But that is the sponsor rescuing the position, not the position defending itself. As it stands, USI is being outgrown organically, outbought inorganically, and out-financed structurally by every peer that matters. In a consolidation endgame, that is the definition of at risk.

How a challenger would attack it

Turn the non-compete regime into a recruiting pitch. USI’s own posture says the book belongs to the system, not the producer — enforced with two-year covenants and a litigation docket (Baggett, Fowler, MacNair, the Lockton countersuit) that Alliant already exploits with team lift-outs. A challenger weaponizes that: equity-heavy producer economics, published book-ownership terms, and legal defense as a signing benefit, aimed at the account managers Glassdoor says sit at the bottom of the pay band getting 1-2% raises. USI retains by contract; the challenger retains by proposition, and every lawsuit USI files is the challenger’s marketing. The second vector is OMNI itself. USI’s whole differentiation is a decade of codified mid-market risk solutions — but that is precisely the asset LLMs commoditize fastest. A tech-native brokerage that pairs modern retrieval over carrier forms, claims data and placement history with a lean producer bench replicates in two years what took USI fifteen, without $4.3B of LBO cost basis or 7x leverage at ~2x coverage consuming the cash that should fund it. Third: with USI closing one acquisition in 2024 while multiples hit 11.8x, a challenger can sign the founder-owned agencies USI can no longer afford — the pipeline that built the firm is now open territory.

Same playbook, new buyer

The USI model — systematized expertise sold to buyers too small for Marsh and too complex for a local agency — transplants cleanly one tier down: the small-commercial segment ($1-10M revenue businesses) that mid-market brokers ignore because commission dollars per account don’t cover a producer’s time. OMNI-style codified solutions plus AI delivery is exactly what makes that segment economic for the first time — an Ask V for businesses that will never meet a USI producer — and USI cannot chase it because its cost structure is built on 10,000 professionals in 200 offices and its debt service demands mid-market commission density. The second shift is vertical: USI’s retirement consulting arm proves the adjacent-advisory motion works, but nobody has run the bundled risk-plus-benefits-plus-retirement play for a single deep vertical — construction trades, medical practices, franchise operators — where a focused platform can out-specialize a generalist’s practice groups. The incumbent won’t follow either move at conviction: KKR’s core strategy needs EBITDA growth to walk leverage below 7x, which locks USI into defending its existing book rather than funding lower-margin new segments.
