Colleagues,

This morning, we made an exciting announcement: Huntington has reached an agreement to acquire Cadence Bank, a $53 billion bank headquartered in Houston, TX and Tupelo, MS with more than 390 locations across Texas and the South.

This marks a significant milestone in Huntington’s growth strategy and is a meaningful step forward in our journey to become the leading people-first, customer-centered bank in the country. Through the partnership, Huntington will build immediate scale in Texas and Mississippi, become a top ten bank in Alabama and Arkansas, and gain a foothold in key high-growth markets like Houston, Dallas, Fort Worth, Austin, Atlanta, Nashville, Orlando and Tampa—creating a powerful platform for further organic growth and investment.

Altogether, this partnership allows us to bring Huntington’s full franchise to eight new states, making the full range of our products and services available across 21 states—from the Midwest to the South to Texas.

Please take a moment to watch this video to learn more.

Dan Rollins, Cadence's Chairman and CEO, and the entire Cadence Senior Management team have been—and will continue to be—outstanding partners throughout this planning process, helping position our combined organization for long-term success. We are grateful for their partnership and delighted that Dan will join as non-executive Vice Chair of Huntington Bancshares Incorporated as well as a director of Huntington Bancshares Incorporated and the Huntington National Bank.

The combination is expected to close in the first quarter of 2026, subject to regulatory approvals and customary closing conditions. Upon conversion, which is expected in the second quarter of 2026, Cadence teams and branches will operate under the Huntington Bank name and brand.

Your continued commitment to looking out for each other—and our customers—has positioned us for this moment. And we thank you for everything you do.

Steve and the ELT
