This Supplement outlines important changes to certain investment options under your flexible premium variable life insurance contract.

The Board of Trustees of Lincoln Variable Insurance Products Trust recently approved a new sub-advisory agreement between Lincoln Financial Investments Corporation and Nomura Investments Fund Advisers, a series of Nomura Investment Management Business Trust ("NIFA") and a new sub-sub-advisory agreement between NIFA and Macquarie Investment Management Global Limited (together, the "New Sub-Advisory Agreements"). The New Sub-Advisory Agreements were approved in connection with the acquisition of Macquarie Asset Management's U.S. and European public investments business (the "Acquisition"). The New Sub-Advisory Agreements will become effective on the closing date of the Acquisition, which is expected to be on or about November 1, 2025 (the "Acquisition Date"). As of the Acquisition Date, the LVIP Macquarie High Yield Fund will change to the LVIP Nomura High Yield Fund. The Acquisition will not affect the fees or expenses of the funds.

All other information about the funds, including principal investment strategies, can be found in the fund's prospectus.
