Subsequent Events	On November 6, 2025, BHF entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Aquarian Holdings VI L.P., a Delaware limited partnership (“Parent”), Aquarian Beacon Merger Sub Inc., a Delaware corporation and an indirect wholly-owned subsidiary of Parent (“Merger Sub”), and Aquarian Holdings LLC, a Delaware limited liability company (“Aquarian Holdings”), solely for the purpose of certain provisions, pursuant to which, at the closing of the transactions contemplated by the Merger Agreement, Merger Sub will merge with and into BHF, with BHF surviving as a wholly owned subsidiary of Parent (the “Merger”). Brighthouse Life Insurance Company will remain an indirect wholly owned subsidiary of BHF after the effective time of the Merger (the “Effective Time”). The consummation of the Merger is subject to the satisfaction or waiver of customary closing conditions, including, among others, the adoption of the Merger Agreement by the affirmative vote of the holders of a majority of the outstanding shares of BHF common stock entitled to vote thereon at a meeting of BHF stockholders and the receipt of certain regulatory approvals, including from insurance regulators in Delaware, New York and Massachusetts. Parent’s and Merger Sub’s obligations are also conditioned upon the absence of a Company Material Adverse Effect (as defined in the Merger Agreement) and the absence of a Burdensome Condition (as defined in the Merger Agreement). The Merger Agreement also contains customary representations, warranties and covenants by each of Parent, Merger Sub, Aquarian Holdings and BHF, including, among others, covenants by BHF to use its reasonable best efforts to conduct its business in the ordinary course consistent with past practice and to refrain from taking certain actions prior to the Effective Time, in each case except with Parent’s consent.
