Summary Prospectus for Existing Investors

May 1, 2024

This summary prospectus (the "Summary Prospectus") summarizes key features of the contract. The statutory prospectus (the "Prospectus") and the Statement of Additional Information ("SAI") for the contract contain more information about the contract's features, benefits, and risks. The Prospectus and SAI are incorporated by reference into this updating Summary Prospectus. You can find the current Prospectus, SAI and other information about the contract online at www.equitable.com/ICSR#EQH146682. You can also obtain this information at no cost by calling 1-877-522-5035, by sending an email request to [email protected], or by calling your financial intermediary.

The Retirement Income Account ("RIA")® is an investment program that allows employer plan assets to accumulate on a tax-deferred basis. This Summary Prospectus only describes RIA. The contracts provide for the accumulation of retirement savings and for income. They also offer a number of payout options.

Additional information about certain investment products, including variable annuities, has been prepared by the Securities and Exchange Commission's staff and is available at Investor.gov.

Updated Information About Your Contract

The information in this Summary Prospectus is a summary of certain contract features that have changed since the Prospectus dated May 1, 2023. This may not reflect all the changes that have occurred since you purchased your contract.

INVESTMENT OPTIONS

Investment Option Name Changes: EQ/ JPMorgan Growth Stock Portfolio (formerly EQ/T. Rowe Price Growth Stock Portfolio)

OTHER

Portfolio Reorganization: Certain portfolios of the EQ Premier VIP Trust (the "Acquired Trust Portfolios") were reorganized into substantially identical, newly created portfolios of the EQ Advisors Trust (the "Acquiring Trust Portfolios"). The investment objectives, policies, principal strategies, principal risks, and the fees and expenses of the Acquired Trust Portfolios and corresponding Acquiring Trust Portfolios are substantially identical, and their Investment Manager did not change. The Acquired Trust Portfolios under your contract were removed as investment options, and the corresponding Acquiring Trust Portfolios were added as available investment options (subject to any applicable allocation restrictions) without impacting your account value, investment allocations, or expenses.

Important information you should consider about the contract

FEES AND EXPENSES
Charges for Early Withdrawals

If you withdraw account value from the RIA, other than in the form of a benefit distribution payment, within 9 years following the date on which the employer plan began its participation in RIA, you will be assessed a contingent withdrawal charge ("CWC") of up to 6% of the amount withdrawn. For example, if you make a withdrawal in the first year, you could pay a CWC of up to $6,000 on a $100,000 withdrawal.

For additional information about CWCs see "Contingent withdrawal charge" in "Charges and expenses" in the Prospectus.

Transaction Charges

In addition to CWCs, you may also be charged for other transactions (if you elect an annuity payout option).

For additional information about transaction charges see "Annuity administrative charge" in "Charges and expenses" later in this Prospectus.

Ongoing Fees and Expenses (annual charges) The following tables describe the fees and expenses that you may pay each year under the contract, depending on the options you choose. Please refer to your contract specifications page for information about the specific fees you will pay each year based on the options you have elected.
Annual Fee Minimum Maximum
Base Contract* 0.25% 1.25%
Pooled Separate Account expenses**, (1) 0.20% 0.84%
Portfolio fees and expenses**, (1) 0.57% 1.40%
Optional benefits available for an additional charge
(for a single optional benefit, if elected)(2)
1.00% 1.00%

* Expressed as an annual percentage of account value.

**  Expressed as an annual percentage of average daily net assets.

(1)  These fees will fluctuate from year to year. These expenses are based on the expenses incurred during the fiscal year ended December 31, 2023.

(2)  As a percentage of amount withdrawn as loan principal at the time the loan is made. Your employer plan may also charge interest on the loan amount at a rate they set.

Because the contract is customizable, the choices you make affect how much you will pay. To help you understand the cost of owning your contract, the following table shows the lowest and highest cost you could pay each year, based on current charges. This estimate assumes that you do not take withdrawals from the contract, which could add contingent withdrawal charges that substantially increase costs.

RISKS
Risk of Loss

The contract is subject to the risk of loss. You could lose some or all of your account value.

For additional information about the risk of loss see "Principal risks of investing in the contract" in the Prospectus.

Not a Short-Term Investment

The contract is not a short-term investment and is not appropriate for an investor who needs ready access to cash because the contract is designed to provide for the accumulation of retirement savings and income on a long-term basis. As such, you should not use the contract as a short-term investment or savings vehicle. A withdrawal charge may apply in certain circumstances and any withdrawals may also be subject to federal and state income taxes and tax penalties.

For additional information about the investment profile of the contract see "Fee table" in the Prospectus.

Risks Associated with Investment Options

An investment in the contract is subject to the risk of poor investment performance and can vary depending on the performance of the investment options available under the contract, (e.g., the Pooled Separate Accounts and the Portfolios). Each investment option, including the guaranteed interest option, has its own unique risks. You should review the investment options available under the contract before making an investment decision.

For additional information about the risks associated with investment options see "Investment options" and "Portfolios of the Trust" in "RIA Investment Options" and Appendix: Portfolio Companies Available Under the Contract in the Prospectus.

Insurance Company Risks

An investment in the contract is subject to the risks related to the Company. Equitable Financial Life Insurance Company is solely responsible to the contract owner and participants for the contract's account value. The general obligations under the contract, including the guaranteed interest option, are supported by our general account and are subject to our claims paying ability. An owner and participant should look solely to our financial strength for our claims-paying ability. More information about Equitable Financial Life Insurance Company, including our financial strength ratings, may be obtained upon request by calling 1-800-789-7771.

For additional information about insurance company risks see "About the general account" in "More information" in the Prospectus.

RESTRICTIONS
Investments

The availability of investment options will vary by employer, and you should refer to your plan documents for a list of the investment options available to you. You may transfer accumulated amounts among the investment options under your contract at any time and in any amount, subject to certain transfer limitations described in the Prospectus. We reserve the right to remove or substitute Portfolios and Pooled Separate Accounts as investment options.

For additional information about the investment options see "Investment options" in "RIA Investment Options" in the Prospectus.

Transfers from the guaranteed interest option may be subject to limitations. From time to time, we may remove certain restrictions that apply to transferring amounts out of the guaranteed interest option. If we do so, we will tell you. We will also tell you at least 45 days in advance of the day that we intend to reimpose those transfer restrictions.

For additional information about the guaranteed interest option see "Guaranteed interest option" in "RIA Investment Options" in the Prospectus.

Optional Benefits

Participant Loans. Not all employer plans will offer loans. Loans are subject to restrictions under federal tax rules and ERISA. Loans generally must be taken from the guaranteed interest option. The minimum loan amount is $1000 and the maximum loan amount is 90% of the balances attributable to the plan participant. We charge a 1% fee at the time a loan is made, and the employer plan may charge interest on the loan, at a rate they set. If a participant fails to repay a loan when due the amount of the unpaid balance may be treated as a withdrawal and as such, be subject to taxes, additional penalty taxes, and a CWC of up to 6% of the unpaid balance if this occurs within 9 years of the date on which the employer began it's participation in the RIA. See "Participant Loans" in "Benefits Available Under the Contract" in the Prospectus.

Optional Participant Recordkeeping Services. This service must be selected by the employer. If it is selected by the employer than the participants must be enrolled and pay the annual fee. Employers who did not elect the option may no longer do so.

TAXES
Tax Implications

You should consult with a tax professional to determine the tax implications of an investment in, and payments received under, the contract. There is no additional tax benefit to you if the contract is purchased through a tax-qualified plan or individual retirement account (IRA). Withdrawals will be subject to ordinary income tax and may be subject to tax penalties. Generally, you are not taxed until you make a withdrawal from the contract.

For additional information about tax implications see "Tax information" in the Prospectus.

CONFLICTS OF INTEREST
Investment Professional Compensation

Some financial professionals may receive compensation for selling the contract, both in the form of commissions or in the form of contribution-based compensation. Financial professionals may also receive additional compensation for enhanced marketing opportunities and other services (commonly referred to as "marketing allowances"). This conflict of interest may influence the financial professional to recommend this contract over another investment.

For additional information about compensation to financial professionals see "Distribution of the contracts" in "More information" in the Prospectus.

Exchanges

Some financial professionals may have a financial incentive to offer a new contract in place of the one you already own. You should only exchange your contract if you determine, after comparing the features, fees, and risks of both contracts, that it is preferable to purchase the new contract rather than continue to own your existing contract.

For additional information about the charges you might incur in connection with an exchange see "Contingent withdrawal charge" in "Charges and expenses" in the Prospectus.

Appendix: Portfolio Companies Available Under the Contract

The table does show the contract's Platform Charge, but the Platform Charge is not reflected in the current expenses or average annual total returns of the portfolios. Expenses would be higher and performance would be lower if these other charges were included. Each Portfolio's past performance is not necessarily an indication of future performance.
