(1) Pursuant to the Put/Call Agreement with the Rollover Shareholders who remained after the Teraco Acquisition, the Rollover Shareholders have a put right on the Remaining Interest of Teraco that can be settled by the Company in Digital Realty Trust, Inc. shares, in cash, or a combination of cash and shares. 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. For additional information regarding the Teraco Acquisition and the defined terms used above, see Note 3. “Business Combinations” to Consolidated Financial Statements contained herein.

(2) The Company has made an adjustment to previously reported amounts to correct an immaterial error in the computation of diluted earnings per share and diluted earnings per unit in each of the interim periods ended June 30, 2023 and September 30, 2023, and for the year ended December 31, 2023. The correction appropriately reduces net income available to common stockholders and unitholders, as applicable, for the loss attributable to the non-controlling interests in Teraco. The impact to earnings per share and earnings per unit for each respective period is summarized in the table below:
