North America growth was double digit within Commercial Risk, with construction and data center activity described by CFO Edmund Reese as on pace for a data center revenue pipeline 3x higher than last year, according to Edmund Reese, CFO, on the Q1 2026 earnings call.
CEO Greg Case emphasized that the Commercial Risk result was broad-based across geographies and product lines, not dependent on any single driver.
Reinsurance delivered 4% organic revenue growth, with treaty placements growing despite 10% to 15% rate pressure at January 1 renewals, offset by strong new business and new logo additions.
Health Solutions grew 4%, led by core Health and Benefits business across EMEA and APAC, partially offset by softer discretionary spend in Talent Solutions.

Aon Stock Financials: Margin Trajectory
The annual income statement shows a business delivering steady revenue and gross profit growth, with operating margin facing modest compression over the last two years despite strong absolute earnings growth.
Revenue grew from $13.4B in FY2023 to $15.7B in FY2024 and $17.2B in FY2025, compounding at 9.4% over one year and 9.2% over five years.
Gross margin held relatively stable, moving from 47.7% in FY2023 to 46.9% in FY2024 before recovering to 47.2% in FY2025.
Operating income grew from $3.8B in FY2023 to $4.4B in FY2024 and $4.7B in FY2025, a solid expansion in absolute terms.
Operating margin, however, compressed from 28.6% in FY2023 to 28.0% in FY2024 and further to 27.3% in FY2025, a multi-year narrowing driven by rising SG&A and amortization tied to the NFP acquisition.
Q1 2026 reversed this direction: adjusted operating margin expanded 70 basis points to 39.1% on an adjusted basis, according to Edmund Reese on the Q1 2026 earnings call, signaling that restructuring savings and ABS-driven efficiency are beginning to offset acquisition integration costs.
What Does the Valuation Model Say?
The TIKR model prices Aon stock at ~$451 in the mid case, implying roughly 45% upside from the current price near ~$312.
The mid case assumes a revenue CAGR of 4% from 2025 through 2035 and a net income margin of 24%, modestly above the 21% reported over the last twelve months.
The Q1 2026 result strengthens the risk/reward picture: fourth consecutive quarter of 6% or better Commercial Risk organic growth, accelerating free cash flow, and confirmed margin expansion guidance remove near-term execution uncertainty from the model.
Aon stock’s investment case is stronger after this report, with the primary variable now being whether mid-single-digit organic growth proves durable as property and reinsurance pricing softens further into 2026.
Sustained mid-single-digit organic growth at scale and a clear margin expansion path make Aon stock’s 45% model discount compelling, but the real question is whether soft reinsurance pricing undercuts the full year.
Bull Case
- Commercial Risk organic growth of 7% in Q1 marks four consecutive quarters at 6% or higher, with new business contribution exceeding 12 points in the segment
- Data center revenue pipeline is on pace to be 3x higher than last year, per Edmund Reese on the Q1 2026 earnings call, expanding the addressable market beyond traditional insurance cycles
- Restructuring savings of $100M targeted for 2026, advancing toward $450M cumulative by 2027, creating a durable margin expansion runway
- $363M free cash flow in Q1, up 332% YoY, supports at least $1B in share repurchases for the full year alongside continued tuck-in M&A
Bear Case
- Reinsurance treaty renewals face 10% to 15% rate pressure, with April 1 data showing rates down 15% to 20% in both the US and Japan
- Wealth segment posted only 1% organic growth in Q1, and Talent Solutions within Health faces softening discretionary spend that management acknowledged extended through Q1 2026
- The TIKR model’s 24% net income margin assumption requires sustained improvement from the 27.3% operating margin recorded in FY2025 alongside higher amortization from NFP integration
- Fiduciary investment income fell 18% YoY to $55M in Q1, with lower interest rates partially offsetting the benefit of higher average balances as rate tailwinds unwind
