Governance profile as a U.S. company Our overarching goal is to create a framework and implement practices consistent with the expectations of our investors and market standards of leading U.S. companies Aegon intends to move its legal seat to Delaware, the state of incorporation of the majority of U.S. public companies. In connection with this, the Company will amend its bye-laws to align Aegon’s governance with U.S. market standards. Key proposed changes include: ✓ Phased declassification of the Board of Directors, with annual elections for all directors beginning in 2030 ✓ Simplification of the capital structure with the elimination of Common Shares B and Special Cause voting by converting all outstanding Common Shares B held by VA on a 40:1 basis into a single class of common stock with equal voting rights ✓ Authorization of preferred stock, as is customary for U.S. listed companies ✓ Abandon the current 2/3 requirement for contested director elections and adopt majority voting in uncontested elections and plurality voting in contested elections 7

Executive Compensation & Omnibus Equity Plan Our compensation philosophy remains anchored in pay-for-performance, benchmarked against relevant U.S. life insurance and retirement peers As part of our planned relocation to the U.S., we are moving from a European-style pay framework to a U.S. market-standard approach: ✓ Going forward, executive compensation will be subject to an annual advisory Say-on-Pay vote ✓ Say-on-Pay will cover our Named Executive Officers, which is broader in scope than our current vote ✓ Shareholders will be asked to approve an Omnibus Equity Plan that sets the aggregate pool of shares available for equity awards and the parameters governing those awards ✓ Equity compensation awarded under the plan will be based on role profile and performance and will consider the practices of relevant U.S. peers. Governance standards expected by institutional investors will be reflected in the plan’s design 10
