01—Abstract
Summary
Summary of the 8-K filed March 17, 2025. Cited figures are marked; the original filing is the authoritative source.
Aon plc disclosed on March 17, 2025 that Eric Andersen has stepped down as President of Aon plc and Aon Corporation, transitioning to a Senior Advisor role through June 2026 under Section 5(a) of his July 2023 employment agreement.
The transition took effect March 14, 2025. Chief Executive Officer Gregory C. Case has assumed the additional title of President, consolidating the top two executive roles in one person.
For investors, this is primarily a management-structure change rather than a financial event. The 8-K states that Mr. Case's compensation arrangements are unchanged; the amendment to his employment agreement only reflects the added title. The filing contains no financial results, guidance, or charges, and the company frames the move as a planned transition, with Andersen citing the successful integration of NFP and a strong executive team as reasons for the timing.
The main items to monitor are whether Case's expanded responsibilities create execution risk across the 3x3 Plan and the Aon United strategy, and whether Andersen's advisory role through June 2026 smooths the handover. The filing does not disclose any change to segment reporting, financial targets, or the broader executive team.

03—Questions
Frequently Asked Questions
Is this executive change a sign of financial trouble at Aon?
The filing does not indicate financial trouble. It contains no results, guidance changes, or charges. The company describes the move as a planned transition, and Andersen attributes it to the successful integration of NFP and a strong executive team.
Will Greg Case's compensation change because he is now also President?
No. The amendment to his employment agreement states that it makes no changes to his compensation arrangements. It only reflects his assumption of the additional President title.
What is Eric Andersen's role going forward?
Andersen moved to a Senior Advisor role reporting to Case, which runs through June 2026. The filing does not describe his specific duties or any compensation terms for the advisory role.
Does combining the CEO and President roles create key-person risk?
Potentially. Case now holds both top executive titles, so investors may watch for execution risk on the 3x3 Plan and the integration of Risk Capital and Human Capital capabilities. The filing does not address succession planning or any plans to add a separate President.
Where can I find more information about Greg Case's background?
The 8-K incorporates Mr. Case's Item 401 and 404 disclosures by reference from Aon's definitive proxy statement on Schedule 14A filed April 29, 2024, rather than restating them in this filing.
