Corebridge Financial, Inc. 8-K

What Happened
Corebridge Financial, Inc. announced in an 8-K filed March 16, 2026 that Nippon Life Insurance Company notified the company on March 11, 2026 that one of its designated directors, Minoru Kimura, will depart the Board effective April 20, 2026. Nippon said the change is due to normal personnel assignment rotations and not due to any disagreement with Corebridge on operations, policies or practices. The director designation rights arise from the Stockholder’s Agreement dated December 9, 2024.

Key Details

• Minoru Kimura will leave the Corebridge Board effective April 20, 2026.
• As of March 16, 2026, Nippon has the right to designate three board members (Nippon Designees), currently including Minoru Kimura, Keith Gubbay and Tomohiro Yao.
• Nippon will replace Mr. Kimura with another Nippon Designee; the Company expects to appoint a replacement after the Board’s good-faith determination, in consultation with outside counsel, that the appointment is consistent with fiduciary duties and applicable law.
• The designation rights are tied to Nippon’s ownership under the Stockholder’s Agreement and continue until Nippon’s share ownership percentage is less than 5%.

Why It Matters
This filing affects board composition and governance: a designated director is leaving and Nippon—an institutional investor with contractual nomination rights—will name a replacement. For investors, the change signals continuity of Nippon’s board representation (three designees as of the filing) and indicates the replacement process will follow the Board’s fiduciary review and legal advice. This is a governance item rather than an operational or financial disclosure; no disagreements with management were reported.
