PE approach to building and scaling insurance brokerages

Executive overview

Insurance brokerage is asset-light, highly cash-generative, and structurally less cyclical than most industries. Brokers earn commissions as a percentage of premiums — so rising rates lift revenue without renegotiating prices. The industry remains fragmented, creating a durable M&A runway.

GTCR's leader strategy — backing proven CEOs in industries they know — is the organising principle. The Assured Partners story shows what compounding looks like when you pair the right CEO with a buy-and-build playbook, twice.

The scarce resource in insurance PE is not deal flow — it's the right CEO.

Why insurance brokerage attracts private equity

• Less cyclical than most sectors: businesses must carry insurance regardless of economic conditions
• Asset-light model; CapEx is a few percent of revenue
• EBITDA converts almost entirely to free cash flow — no capital intensity below the line
• Tuck-in M&A generates significant tax shields, improving cash returns further
• Brokers don't set customer prices; commissions rise automatically with premiums
• Industry remains highly fragmented — thousands of independent brokers still available to acquire
• Valuations have roughly doubled over 25 years (from ~8.5x to 17–19x EBITDA) as scale and recurring revenue characteristics became better understood

The leader strategy

• CEO selection is the primary investment decision — not deal sourcing
• Target CEOs who have created equity value for prior shareholders, not just revenue growth
• Domain match matters: an insurance brokerage CEO should run an insurance brokerage, not an adjacent vertical
• Great CEOs attract great lieutenants — a strong pipeline of followers signals leadership quality
• CEOs who can transcend size are rare; many excel at a specific scale band

What makes a strong insurance brokerage platform

• Diversification across carriers, customers, producers, and end markets — single dependencies are a red flag
• Centralised infrastructure (agency management system, technology, compliance) before pursuing M&A scale
• Retention is the core KPI: generalists retain at high 80s to low 90%; specialists reach mid-to-high 90s
• Specialisation by vertical (e.g. long-term care, commercial trucking) drives retention and acquisition flow
• Organic growth is the premium valuation driver; pure M&A roll-ups trade at a discount

The M&A playbook

• Acquire founders who reinvest proceeds; freed from admin, they typically accelerate production
• Integrate onto one agency management system within 90 days — leaving disparate systems cedes operational control
• Tuck-ins gain access to centralised centres of excellence, improving their client offering immediately
• Fragmentation persists: sold founders run out non-competes and start new businesses, replenishing supply

Revenue model and growth drivers

• Commission-based in the SME and mid-market; fee-based only for the very largest corporates
• Growth runs at roughly inflation-plus, driven by social inflation (rising jury verdicts) and new risk categories
• Cyber insurance is structurally different — risk is real-time and ongoing rather than discrete, complicating carrier underwriting
• Hard markets (rising premiums) can temporarily increase churn as customers shop; attrition rarely finds a better price
• EBITDA margins for mature brokers: 28–35%; higher-margin operators typically show lower organic growth

Technology and the integration challenge

• Insurance brokerage is 10–15 years behind other industries in technology adoption
• A single agency management system is the foundation: it enables carrier negotiations, regulatory filings, and real-time data
• AI overlay should free broker time for selling — still early innings (roughly third inning in baseball terms)
• People resist system changes; cultural readiness for integration is as important as the technology itself

Risks and market cycles

• No single customer risk: largest customer represents well under 1% of revenue at scale
• AI is an efficiency tool, not an existential threat to the broker's advisory role
• Hard/soft market cycles are driven by carrier cash flow profitability, not purely by macro conditions
• Soft markets (falling premiums) compress commissions and slow growth; tuck-in acquisition pricing also softens, partially offsetting
• Regulation is state-by-state; scale gives larger brokers a compliance advantage but no near-term regulatory threat on the horizon

Exit landscape

• Five to six players globally with $1B+ EBITDA; expect further consolidation at the top
• Strategic acquirers (e.g. AJG buying Assured Partners for $13B) remain the primary exit path for large platforms
• IPO pipeline likely to open for several PE-backed brokers in coming years
• Re-partnering with a proven CEO (as GTCR did with Jim Henderson on Assured Partners round two) offers asymmetric upside by eliminating management alignment risk
