Brown & Brown: Decentralized Operating Model Driving Best-in-Class Margins
Grew revenue 12.9% to $4.81B with 35.2% EBITDAC margin — best-in-class among insurance brokers.
Brown & Brown, a Large Enterprise Insurance Brokerage & Risk company, created value through Organizational Design and New Customer Acquisition.
Brown & Brown has distinguished itself in the insurance brokerage industry through a decentralized operating model that pushes P&L accountability to individual profit centers. Unlike peers that centralize operations post-acquisition, Brown & Brown allows acquired agencies to retain local autonomy while providing access to the company's global resources, specialty capabilities, and collaborative network. By 2023, the company had revenues of approximately $4.26 billion. The company's challenge was to maintain its industry-leading margins and organic growth rate while scaling through acquisitions in an increasingly competitive M&A environment.
In 2024, Brown & Brown executed 32 acquisitions while maintaining its decentralized model. Each acquired business retained its local brand, leadership, and P&L accountability, with monthly performance comparisons driving bonus decisions based on profitability improvements. The company's profit-sharing structure — where profit-sharing contingent commissions are tied to underwriting results, volume, and growth — incentivized both organic growth and operational discipline at every level. Brown & Brown invested in teammate equity ownership to align incentives and drove strong new business generation alongside high customer retention. The decentralized model enabled rapid responsiveness to local market conditions while the parent company provided scale advantages in carrier negotiations and specialty product access.
Total revenues reached $4.81 billion in 2024, a 12.9% increase from 2023. Organic revenue growth was 10.4% for the full year. Adjusted EBITDAC margin expanded to 35.2% from 33.9% in 2023, representing best-in-class profitability among insurance brokers. Income before income taxes grew 13.7% to $1.3 billion, with margin increasing to 27.1%. Adjusted EBITDAC was $1.7 billion, up 17.0%. The company converted approximately two-thirds of EBITDA and roughly a quarter of revenue into free cash flow, maintaining strong capital returns including $154 million in dividends, a 14.1% increase from 2023.
Deeply embedded decentralized culture that preserves entrepreneurial incentives post-acquisition. Profit-sharing and teammate equity ownership creating alignment between local operators and company-wide goals. Disciplined acquisition criteria focused on cultural fit alongside financial metrics. Monthly P&L accountability cadence at the profit center level driving continuous margin improvement.
| Metric | FY2023 | FY2024 |

| Organic revenue growth | — | 10.4% |
| Adjusted EBITDAC margin | 33.9% | 35.2% (+130 bps) |
| Income before income taxes | ~$1.14B | $1.30B (+13.7%) |
| Acquisitions completed | — | 32 |
The conventional assumption about decentralized operating models is that they sacrifice efficiency for flexibility — that local autonomy prevents the cost synergies that centralization delivers. Brown & Brown's 35.2% EBITDAC margin in FY2024, tied with AJG for the top of the public insurance brokerage peer group, is the direct rebuttal. A $4.8 billion firm running deliberately decentralized operations — retained local brands, local management, local P&L accountability — achieved a margin that matches or exceeds peers running centralized integration models at comparable or larger scale.
The mechanism is producer retention eliminating the costs that centralized models incur. Centralized post-acquisition integration — standardizing brand, compensation, systems, and reporting — consumes management bandwidth, creates producer turnover (the primary integration risk in brokerage), and generates the client churn that follows producer departures. Each producer who leaves and each client who follows represents both lost revenue and replacement cost: 12–24 months of relationship development to win a comparable account. The decentralized model's "inefficiency" is actually the absence of these integration costs. Retained producers, retained clients, retained local market expertise — the margin that would have been consumed by integration is instead flowing to EBITDAC.
The 130 basis point expansion from FY2023 to FY2024 on a $4.8 billion revenue base reflects overhead per dollar of revenue improving as the acquired base grows. The Programs segment (MGA economics) contributes margins structurally above commodity brokerage and reinforces the blended EBITDAC. At this margin level on this revenue base, Brown & Brown's decentralized model is the most compelling counter-evidence against the assumption that scale requires centralization.
