Thesis Summary

Aon's operating momentum supports a constructive but valuation-cautious view. In the second quarter of 2026, organic revenue grew 5%, adjusted operating margin expanded 70 basis points and adjusted EPS increased 9%. Management reaffirmed full-year objectives for mid-single-digit-or-greater organic growth, 70-80 basis points of adjusted margin expansion and double-digit free-cash-flow growth. The principal execution concern is cash conversion: quarterly free cash flow declined 34%, leaving first-half growth at 4%.

Bear CaseDownside scenario
$339.0018%

Organic growth falls below the mid-single-digit objective or cash conversion fails to recover from the second-quarter decline, limiting financial flexibility and weakening confidence in the expected margin and free-cash-flow outcomes.

Base CaseCentral scenario
$402.4758%
Matches the consensus mean

Aon delivers approximately the reaffirmed 2026 framework: mid-single-digit-or-greater organic growth, 70-80 basis points of adjusted margin expansion and double-digit free-cash-flow growth.

Bull CaseUpside scenario
$445.0024%

Aon exceeds its organic-growth and margin objectives as net new business, retention, restructuring savings and technology investments produce operating leverage, while free-cash-flow growth accelerates to double digits for 2026.

Scenarios are anchored to street consensus at the research date, with our probabilities and rationale.

Key Investment Merits
  • Second-quarter organic revenue growth of 5%, adjusted operating-margin expansion of 70 basis points and adjusted EPS growth of 9% demonstrate resilient underlying execution.
  • Aon returned $775 million to shareholders during the second quarter through $600 million of repurchases and $175 million of dividends, while retaining approximately $7.7 billion of repurchase authorization at June 30, 2026.

Key Investment Risks
  • Second-quarter free cash flow declined 34%; first-half free cash flow increased only 4% despite management's double-digit full-year growth objective.
  • Second-quarter reported revenue increased only 2%, while Human Capital revenue declined 4%, reflecting the effect of divestitures and making delivery of the organic-growth and cash-flow outlook important to the thesis.
