Subject: Our Transformational Merger with Equitable Holdings

March 26, 2026

Dear Colleagues:

I'm writing to share that Corebridge Financial has entered into a definitive agreement to combine with Equitable Holdings. This is a significant step that will build on our foundation, accelerate our growth and enable us to better support our customers. You can read more here.

Our mission is clear: to help people retire with dignity and confidence. Every day, we provide customers with the ability to protect, grow and secure their financial future. Equitable Holdings shares that same commitment, and their company is a natural, complementary fit with ours. Equitable is a storied financial services institution with deep expertise in retirement, asset management and strong wealth capabilities. Uniting will allow us to build on the momentum each of our companies has established.

Together, Corebridge and Equitable will create a leading retirement, life, wealth and asset management company reaching more than 12 million customers and $1.5 trillion in assets under management and administration. We will have enhanced scale and a diversified portfolio of businesses with well-established global brands, better enabling us to support financial professionals and institutions. When we serve our customers, we build a stronger future for all our stakeholders, including our colleagues.

Our combined company will have a world-class, multi-channel distribution network and an expanded offering of innovative products and services, creating a balanced and resilient business. We'll also be able to accelerate our digitization and technology transformation, which will further support the customer experience. All of this work will be driven by Corebridge and Equitable's closely aligned cultures grounded in service excellence, risk management and strong execution. As one company, we will stay true to the values that define us.

What This Means for You and Next Steps

While today's announcement marks an important milestone, please keep in mind that it is only the first step in the process. We expect the transaction to close by year-end of 2026, subject to customary closing conditions, including the receipt of regulatory approvals and approval of shareholders of both Corebridge and Equitable.

Upon closing of the transaction, our combined company's leadership team will leverage the expertise and talent of both Corebridge and Equitable. I will serve as President and Chief Executive Officer of the combined company, and Robin Raju, Chief Financial Officer of Equitable, will serve as Chief Financial Officer of the combined company. Similarly, our 14-person Board of Directors will include seven directors designated by each company. I will serve as a director on the Board and Mark Pearson, Chief Executive Officer of Equitable, will serve as Executive Chair. I look forward to working closely with Mark, Robin and the Board to capture the exciting opportunities ahead.

The combined company will operate under the Equitable name, given its more than 165-year history, and it will be headquartered at our campus in Houston, Texas. There are still many decisions to be made, and we are committed to thoughtful integration planning following the close of the transaction. We will soon establish a dedicated team focused on determining the best plan for bringing our companies together, and we look forward to updating you on key milestones.

Until the close of the transaction, it is business as usual. Corebridge and Equitable will remain separate companies and continue operating independently. Your roles and day-to-day responsibilities are not changing at this time and our dedication to serving our customers with consistency and purpose continues.

I will be hosting a fireside chat at 3:00 p.m. ET today to share some additional perspective. You will receive details about the event shortly. I look forward to talking with you then.

I want to thank each of you for the role you have played in building Corebridge. This transaction would not be possible without your hard work and the trust you've earned from those we serve. Let's stay focused on our priorities, keep winning with our customers and move forward together with confidence for what's ahead.

Sincerely,

Marc Costantini

The foregoing list of factors is not exhaustive.
