Rate Sheet Supplement dated    , 2025 to the current prospectus for:

This Rate Sheet Supplement (this “Supplement”) updates certain information in the prospectus dated May 1, 2025 you received and in any supplements to the prospectus (collectively, the “Prospectus”). You should read this Supplement in conjunction with the Prospectus and retain it for future reference. Unless otherwise indicated, all other information included in the Prospectus remains unchanged. The terms and section headings we use in this Supplement have the same meaning as in the Prospectus. We will send you another copy of any prospectus or supplement without charge upon request. Please contact the customer service group referenced in the Prospectus.

Under the Guaranteed minimum income benefit, we will apply an initial Annual Roll-up rate and an initial Deferral Roll-up rate during the first seven years of your contract, beginning on the date your contract is issued. For more information, see “Annual Roll-up rate” and “Deferral Roll-up rate” in the “Benefits available under the contract” section of the Prospectus. The effective date of the following rates is    , 2025 (the “Rate effective date”) until superseded as described below.

Initial Deferral Roll-up rate: 7.0% — See the “Important note for owners age 49 or younger” below.

Guaranteed Roll-up floor: 7.0%

Funding Age for GMIB: 50

If the contract is jointly owned, the GMIB can only be elected and funded if both owners are ages 50 through 80 (ages 50-70 for Series CP^®).

Important note for owners age 49 or younger: Funding of the Guaranteed minimum income benefit and any guaranteed minimum death benefit you elect if you also have the Guaranteed minimum income benefit is only permitted starting at age 50. If you are between the ages of 43 and 49 at the time your contract is issued, the initial Roll-up rates specified in this Supplement will only apply after you attain age 50 for the amount of time then remaining in your first seven contract years. If you are age 42 or younger at the time your contract is issued, the initial Roll-up rates will never apply to your contract, as illustrated in the following chart:

GMIB Annuity Purchase Factors are applied to determine your periodic Lifetime GMIB payments under the GMIB. The GMIB annuity purchase factors are:

GMIB Annuity Purchase Factor Floor:

Single Life: 0.0% for GMIB Exercise Ages 60 - 65 and 3.11% for GMIB Exercise Ages 66 - 95

Joint Life⁽¹⁾: 0.0% for GMIB Exercise Ages 60 - 65 and 2.49% for GMIB Exercise Ages 66 - 95

Lifetime GMIB payments are calculated by applying your GMIB benefit base (less any applicable withdrawal charge remaining) to the greater of (1) the guaranteed GMIB annuity purchase factors specified above, or (2) the GMIB annuity purchase factor floor specified above.

GMIB current Charge (as a percentage of the GMIB benefit base): 1.40%

GMDB current Charges (as a percentage of the benefit base) and issue ages:

The rates, funding age, GMIB annuity purchase factors, and charges in this Supplement can be superseded. The rate effective date of a subsequent Rate Sheet Supplement will be at least 10 days after it is filed.

If you sign your application on or after the above rate effective date and we issue you a contract based on that application during the Rate lock-in period (generally 75 days after the application is signed) and then (1) a subsequent Rate Sheet Supplement with one or more terms more favorable than the current Rate Sheet Supplement becomes effective and remains effective through your contract issue date, and (2) none of the terms on the subsequent Rate Sheet Supplement are less favorable than the current Rate Sheet Supplement, then we will change your terms to match all of the terms on the subsequent rate sheet supplement.

If we issue you a contract based on that application after the Rate lock-in period ends, the initial Annual Roll-up or Deferral rate, guaranteed Roll-up floor, GMIB funding age, GMIB annuity purchase factors, GMIB annuity purchase factor floor rate and age, and/or charge(s) applicable to your contract will be those in effect on the date your contract is issued based on the Rate Sheet Supplement then in effect. The terms in that supplement could be less favorable than those in this supplement.

See “Rate lock-in period” in the “Benefits available under the contract” section of the Prospectus. The Rate lock-in period may vary in some states. See Appendix “State contract availability and/or variations of certain features and benefits” in the Prospectus.

The By-Laws of Equitable Financial Life Insurance Company (the “Company”) provide, in Article VII, as follows:

(a) To the extent permitted by the law of the State of New York and subject to all applicable requirements thereof:

The directors and officers of the Company are insured under policies issued by X.L. Insurance Company, Arch Insurance Company, Endurance Specialty Insurance Company, U.S. Specialty Insurance, ACE, Chubb Insurance Company, AXIS Insurance Company, Zurich Insurance Company, AWAC (Allied World Assurance Company Ltd.), Aspen Bermuda XS, CNA, AIG, Nationwide, Berkley, Berkshire, SOMPO, Chubb, Markel, Ascot, Bowhead, and Westfield. The annual limit on such policies is $300 million, and the policies insure the officers and directors against certain liabilities arising out of their conduct in such capacities.

To the extent permitted by law of the State of New York and subject to all applicable requirements thereof, Equitable Distributors, LLC and Equitable Advisors, LLC have undertaken to indemnify each of its respective directors and officers who is made or threatened to be made a party to any action or proceeding, whether civil or criminal, by reason of the fact the director or officer, or his or her testator or intestate, is or was a director or officer of Equitable Distributors, LLC and Equitable Advisors, LLC.

Insofar as indemnification for liability arising under the Securities Act of 1933 (“Act”) may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
