The Board of Governors of the Federal Reserve System (the “Federal Reserve”) informed Santander Holdings USA, Inc. (“SHUSA”) on June 27, 2025, of SHUSA’s updated stress capital buffer (“SCB”) requirement, which becomes effective on October 1, 2025. SHUSA’s updated SCB will be 3.4% of its common equity Tier 1 capital (“CET1”), resulting in an overall CET1 capital requirement of 7.9%.

SHUSA’s strong capitalization supports our planned capital actions, and the updated SCB is consistent with our long-term capital efficiency objectives. As of March 31, 2025, SHUSA maintained $5.0 billion of excess CET1 capital over the updated 7.9% capital requirement.

As a Category IV firm under the Federal Reserve’s tailoring rule, SHUSA was not subject to the Federal Reserve’s 2025 supervisory stress test and SHUSA’s results were not publicly released.

SHUSA completes its own stress tests utilizing our internally developed bank holding company stress scenario as well as the scenarios provided by the Federal Reserve. In our 2025 stress testing exercise, SHUSA maintains a strong capital position under all forecasted scenarios. SHUSA’s internal recessionary stress scenario includes lower interest rates, high unemployment and large shocks to used car and commercial real estate prices.
