Material Event (Form 8-K)

Item 8.01. Other Events.

On March 27, 2026, Jackson Financial Inc. (the "Company" or "JFI") filed with the U.S. Securities and Exchange Commission (the "SEC"), a prospectus supplement (the "Prospectus Supplement") relating to the resale of up to 4,715,554 shares of JFI's common stock, $0.01 par value per share (the "Shares"), by the selling securityholder identified in the Prospectus Supplement, or any of its pledgees, donees, assignees and successors-in-interest, or collectively, the permitted transferees. The Prospectus Supplement was filed to supplement and amend the base prospectus dated January 17, 2025, which together form a part of the Company's existing automatic shelf registration statement on Form S-3ASR (File No. 333-284340), filed by the Company with the SEC on January 17, 2025, and effective upon that filing.

The filing of the Prospectus Supplement is not itself a sale of securities by the selling securityholder and does not necessarily mean that the selling securityholder will choose to sell any shares of common stock. If any shares of common stock are sold by the selling securityholder, the Company will not receive any proceeds from that sale.

The Company is filing this current report to provide the legal opinion as to the validity of the shares of common stock covered by the Prospectus Supplement, which is attached hereto as Exhibit 5.1 and is incorporated herein by reference.
