Aon plc has announced the immediate departure of Edmund Reese as chief financial officer. Nadin Virani has been named interim CFO, and the firm has launched a search for a permanent successor.
Reese, who joined Aon as CFO in 2022, is leaving "to pursue opportunities outside the firm", the Dublin-headquartered broker said. He will remain as senior adviser to president and CEO Greg Case through August 16, 2027 to support the transition.
Virani steps up from his role as Aon's global head of corporate planning and analytics, where he oversaw financial planning, cash management and budgeting. At American Express, he held CFO positions in London, Frankfurt, and New York over 18 years, covering international lending, insurance and merchant pricing. Before that, he served as head of corporate planning at Broadridge Financial.
Aon confirmed it has engaged an executive search firm to conduct an internal and external search for a permanent CFO.
Alongside the announcement, Aon reaffirmed its full-year 2026 financial guidance, targeting mid-single-digit or greater organic revenue growth and double-digit free cash flow growth. It is also aiming for 70 to 80 basis points of adjusted operating margin expansion. That guidance is consistent with the update provided in its second-quarter earnings release in July 29.
The Q2 results showed 5% organic revenue growth and 2% total revenue growth to US$4.2 billion. Risk Capital revenue grew 5% to US$3 billion, driven by commercial risk and reinsurance solutions, while adjusted operating income rose 5% to US$1.23 billion.
Aon issued the guidance reaffirmation on the same day as the CFO announcement. The move signalled that the firm was conscious of managing the continuity message for clients and investors.
The Reese departure follows a series of senior-level transitions at Aon in recent years. In March 2025, long-serving president Eric Andersen stepped back from his executive role. He took up a senior adviser position reporting to Case, the same structure now in place for Reese.
Aon absorbed the Andersen transition without disruption to its financial trajectory. The firm reported three consecutive quarters of mid-single-digit organic revenue growth through to Q2 2026.
The firm is in the third and final year of its 3x3 Plan. The strategy is built around risk capital, human capital and business services acceleration. That plan is on track to deliver approximately US$350 million in annualised savings by year-end, according to Aon's Q2 2026 results commentary.
