FORTITUDE LIFE INSURANCE & ANNUITY COMPANY VARIABLE ACCOUNT B

Supplement dated December 31, 2025

to Prospectuses and Updating Summary Prospectuses dated May 1, 2025

This Supplement should be read in conjunction with the current Prospectus and Updating Summary Prospectus ("Prospectus(es)") for your Annuity and should be retained for future reference. This Supplement is intended to update certain information in the Prospectus for the variable annuity you own and is not intended to be a prospectus or offer for any other variable annuity that you do not own. Defined terms used herein and not otherwise defined herein shall have the meanings given to them in the Prospectuses and Statements of Additional Information. If you would like another copy of the current Annuity or Portfolio Prospectus, please call us at 1-800-879-7012.

This Supplement describes changes to the variable investment options available in your Annuity.

AST Bond Portfolio 2025

Effective on or about December 31, 2025, the AST Bond Portfolio 2025 will be closed and liquidated and, as a result, all references to the AST Bond Portfolio 2025 will be deleted from the Prospectus.

AST Portfolio Addition

Effective on or about January 2, 2026, the AST Bond Portfolio 2037 (the "Portfolio") will be added to your Annuity as a variable investment option. Please note, however, that this variable investment option is not available for the allocation of Purchase Payments or for transfers - either incoming or outgoing. This Portfolio is available only with certain optional living benefits.

In conjunction with the changes described above, the table captioned "Portfolios Available Under the Annuity" in the "Appendix A" section of the Prospectus will be revised to add the following information:

PGIM Fixed Income is a business unit of PGIM, Inc.

PGIM Investments LLC manages each of the Portfolios of the Advanced Series Trust (AST). AST Investment Services, Inc. serves as co-manager, along with PGIM Investments LLC, to many of the Portfolios of AST.

¹ These Portfolios are also offered in other variable annuity contracts that utilize a predetermined mathematical formula to manage the guarantees offered in connection with optional benefits.

Those other variable annuity contracts offer certain optional living benefits that utilize a predetermined mathematical formula (the "formula") to manage the guarantees offered in connection with those optional benefits. The formula monitors each contract Owner's Account Value daily and, if necessary, will systematically transfer amounts among investment options. The formula transfers funds between the Sub-accounts for those variable annuity contracts and an AST bond Portfolio Sub-account or a fixed account (those AST bond Portfolios or a fixed account may not be available in connection with the annuity contracts offered through this prospectus). You should be aware that the operation of the formula in those other variable annuity contracts may result in large-scale asset flows into and out of the underlying Portfolios that are available with your contract. These asset flows could adversely impact the underlying Portfolios, including their risk profile, expenses and performance. Because transfers between the Sub-accounts and the AST bond Sub-account or a fixed account can be frequent and the amount transferred can vary from day to day, any of the underlying Portfolios could experience the following effects, among others:

The efficient operation of the asset flows among Portfolios triggered by the formula depends on active and liquid markets. If market liquidity is strained, the asset flows may not operate as intended. For example, it is possible that illiquid markets or other market stress could cause delays in the transfer of cash from one Portfolio to another Portfolio, which in turn could adversely impact performance.

Before you allocate to the Sub-account with the Portfolios listed above, you should consider the potential effects on the Portfolios that are the result of the operation of the formula in the variable annuity contracts that are unrelated to your Variable Annuity. Please work with your financial professional to determine which Portfolios are appropriate for your needs.
