Unless otherwise indicated, the information included in your Prospectus remains unchanged. The terms we use in this Supplement have the same meaning as in your Prospectus unless a new term is defined or an existing term in your Prospectus is revised by this Supplement.

Metropolitan Life Insurance Company ("MetLife") as depositor and sponsor of Metropolitan Life Separate Account UL (the "Separate Account") for the Equity Advantage VUL policiesis redeeming shares in the JPMorgan Global Active Allocation Portfolio - Class B underlying fund investment option in which the Division invests ("Existing Fund") as of the close of the New York Stock Exchange on or about April 24, 2026 ("Substitution Date").

On the Substitution Date, units of the above-referenced Divisions will be replaced with units of the MetLife Multi-Index Targeted Risk Portfolio - Class B Division ("Replacement Fund").

The Division that invests in the Existing Fund will continue to be available for investment until the close of business on the New York Stock Exchange on the business day before the Substitution Date. Any premium payment, allocation election, transfer or withdrawal allocation (including any applicable Systematic Withdrawal Program and automated investment strategies) or other transaction involving the Division that invests in the Existing Fund on and after the Substitution Date, will default to the Division that invests in the Replacement Fund, as described more fully below.

On the Substitution Date, MetLife will carry out the substitution by redeeming shares of the Existing Fund held in the Separate Account and purchasing shares of the Replacement Fund. The substitution will result in any Account Value you have allocated to Division investing in the Existing Fund, in effect, being transferred to the Division investing in the Replacement Fund.

The investment objective and policies of the Replacement Fund, along with information about the Replacement Fund's investment adviser, are in the Replacement Fund's prospectus, which you should read carefully.

Prior to the Substitution Date. From the date of this Supplement until the Substitution Date, policy owners with allocations in the Division that invests in the Existing Fund may continue to allocate premium payments and transfer allocations to any other available Division in accordance with the terms of the policy. During this period, any transfers from a Division that invests in an Existing Fund will not be treated as a transfer for purposes of transfer limitations and fees that may otherwise be applicable under the terms of your policy. Frequent trading and rider allocation plan limitations will continue to apply. You may affect transfers by written request, telephone or by any other method we make available under your policy and as described in the prospectus.

On the Substitution Date. At the close of business on the Substitution Date, MetLife will redeem proceeds from the Division that invests in the Existing Fund. These proceeds will then be used to purchase units in the Division that invests in the Replacement Fund. The substitution will occur at relative net asset values of the Existing Fund and Replacement Fund. All policy owners affected by the substitution will receive written confirmation of the transaction. Your account value will be the same as before the substitution. However, the number of units you receive in the Division that invests in the Replacement Fund will be different from the number of units you owned in the Division that invested in the Existing Fund, due to the difference in unit values. The substitution transaction will not be treated as a transfer for the purposes of transfer limitations. There will be no tax consequences as a result of the substitution transactions.

After the Substitution Date. Effective immediately following the Substitution Date, the Division that invested in the Existing Fund will no longer be available as an investment option in the policy. Additionally, from the Substitution Date through 30 days after the Substitution Date, policy owners may reallocate amounts that were substituted into the Division that invests in the Replacement Fund to any other Division without the transfer being treated as a transfer for purposes of transfer limitations and fees that would otherwise be applicable under the terms of the policy. Once the substitution occurs, any premium payment, allocation election, transfer or withdrawal allocation or other transaction involving the Division that invested in the Existing Fund will be allocated to the Division that invests in the Replacement Fund and will become allocation instructions until you tell us otherwise. Frequent trading and any limitations imposed by riders will continue to apply.

Information about the Replacement Fund, its investment policies, risks, fees and expenses and all other aspects of its operations, can be found in its prospectus, which you should read carefully. AS WITH THE EXISTING FUND, THERE IS NO ASSURANCE THAT THE REPLACEMENT FUND WILL ACHIEVE ITS STATED OBJECTIVES.

As of the Substitution Date, all references in the Prospectus to the Division that invests in the Existing Fund and the Existing Fund are replaced with references to the Division that invests in the Replacement Fund and the Replacement Fund, as applicable.
