Capital Planning and Regulatory Stress Testing

During the third quarter and first nine months of 2026, we repurchased $2.6 billion and $7.9 billion of our common stock, respectively.

As a result of the Federal Reserve’s February 2026 action to maintain stress capital buffer requirements for all participating firms at their current levels, and the Federal Reserve’s September 2026 SCB Averaging Rule, which shifts the annual effective date from October 1 to January 1, the Company’s current stress capital buffer requirement of 4.5% will remain in effect until a new requirement becomes effective on January 1, 2028. Therefore, the Company’s minimum capital requirements plus the standardized approach capital conservation buffer for CET1 capital, Tier 1 capital and total capital ratios under the stress capital buffer framework will remain at 9.0%, 10.5% and 12.5%, respectively, through January 1, 2028.

On June 24, 2026, the Federal Reserve released the results of its supervisory stress tests for the 2026 cycle, which did not impact the Company’s stress capital buffer requirement.

For a description of the regulatory capital planning rules and stress testing requirements to which we are subject, see “Part I—Item 1. Business—Supervision and Regulation” in our 2025 Form 10-K and for additional information on recent regulatory developments, see “Supervision and Regulation” in this Report.

Equity Offerings and Transactions

On September 1, 2026, we redeemed all outstanding shares of our Fixed Rate Reset Non-Cumulative Perpetual Preferred Stock, Series M for $1.0 billion. The redemption reduced our net income available to common stockholders by $12 million in the third quarter of 2026, as we recognized the previously deferred issuance costs associated with this series.
