Aon plc Announces CFO Transition; Names Interim CFO Nadin Virani

What Happened
Aon plc announced on August 17, 2026 that Edmund Reese will transition from his role as Executive Vice President and Chief Financial Officer to serve as a senior advisor to the company effective August 17, 2026 through August 16, 2027 under a Letter Agreement (filed as Exhibit 10.1). The company named Nadin Virani, 49, as interim Chief Financial Officer effective the same date. Mr. Virani has been Aon’s Global Head of Corporate Planning and Analytics since January 2025 and previously held finance leadership roles at Broadridge and American Express.

Key Details

• Transition effective date: August 17, 2026; Reese’s senior-advisor term runs through August 16, 2027.
• Interim CFO: Nadin Virani (age 49); Aon’s Global Head of Corporate Planning & Analytics since Jan 2025.
• Compensation changes for interim role: Virani’s annual base salary increased by $50,000 per month while serving as interim CFO; he is eligible for an additional cash bonus equal to the total additional base salary earned during the interim term, payable within 30 days after the term ends.
• Benefits: Virani remains eligible for the Company’s generally available employee benefit plans.
• Documentation: Letter Agreement between Edmund Reese and Aon Corporation filed as Exhibit 10.1 to the 8-K.

Why It Matters
A change in the chief financial officer role is material for investors because the CFO leads financial planning, reporting and communication around earnings and guidance. This filing signals a planned leadership transition rather than an abrupt departure: Reese will remain involved as a senior advisor for up to one year, and Aon appointed an internal finance executive with recent company and industry planning experience as interim CFO. Investors should watch for a future announcement naming a permanent CFO and monitor any subsequent disclosures about financial strategy, reporting, or guidance.
