As of September 30, 2025, the Corporation’s management, with the participation of the Corporation’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Corporation’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)), that are designed to ensure that information required to be disclosed by the Corporation in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms. Based on such evaluation, such officers have concluded that, as of September 30, 2025, the Corporation’s disclosure controls and procedures are effective.

There have been no changes in the Corporation’s internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15 and 15d-15 under the Exchange Act during the last fiscal quarter that have materially affected, or that are reasonably likely to materially affect, the Corporation’s internal control over financial reporting.

The information presented under the caption “Legal Proceedings” in Note 20—Commitments and Contingent Liabilities included under Part I, Item 1 of this Form 10-Q is incorporated herein by reference.

Refer to “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024, for a discussion of risks identified as being most significant to Northern Trust.

(c) The following table shows certain information relating to the Corporation’s purchases of common stock for the three months ended September 30, 2025.

TABLE 78: REPURCHASES OF COMMON STOCK

*(1)*572,209 shares were repurchased under the October 2021 stock repurchase authorization between July 1 and July 21, 2025. 271,426 shares were repurchased under the New Stock Repurchase Authorization between July 22 and July 31, 2025

On July 22, 2025 the Corporation’s Board of Directors approved a new common stock repurchase authorization (the “New Stock Repurchase Authorization”) authorizing, but not obligating, the repurchase of up to $2.5 billion (the “Maximum Program Amount”) of the Corporation’s outstanding shares of common stock from time to time. The New Stock Repurchase Authorization replaces the previously announced authorization approved on October 19, 2021, for which there had been approximately 4.8 million shares of remaining repurchase capacity as of the date of the New Stock Repurchase Authorization after taking into account 572,209 shares repurchased between July 1, 2025 and the date of the New Stock Repurchase Authorization. All funds expected in connection with repurchases after the New Stock Repurchase Authorization shall count against the Maximum Program Amount. The New Stock Repurchase Authorization has no expiration date. Thus the Corporation retains the ability to repurchase when circumstances warrant and applicable regulation permits.

The Corporation expects to acquire shares of common stock under the New Stock Repurchase Authorization through open market transactions, block trades, privately negotiated transactions, and/or pursuant to any trading plan that may be adopted by the Corporation’s management in accordance with federal securities laws from time to time, including pursuant to Rule 10b5-1 of the Exchange Act. The timing and actual number of shares of common stock repurchased will depend on a variety of factors including price, corporate and regulatory requirements, market conditions, and other corporate liquidity requirements and priorities. The New Stock Repurchase Authorization does not obligate the Corporation to acquire a specific dollar amount or number of shares and may be modified, suspended or discontinued at any time. Please refer to Note 10—Stockholders’ Equity to the consolidated financial statements provided in Part I - Item 1. Consolidated Financial Statements (unaudited).
