(1) As part of the acquisition of Teraco in 2022, certain of Teraco's minority indirect shareholders (“Rollover Shareholders”) have the right to put their shares in an upstream parent company of Teraco (“Remaining Interest”) to the Company in exchange for cash or the equivalent value of shares of the Company common stock, or a combination thereof. Under U.S. GAAP, diluted earnings per share must be reflected in a manner that assumes such put right was exercised at the beginning of the respective periods and settled entirely in shares. The amounts shown represent the redemption value of the Remaining Interest of Teraco divided by Digital Realty Trust, Inc.’s average share price for the respective periods. The put right is exercisable by the Rollover Shareholders for a two-year period commencing on February 1, 2026.
