| Amendment Description | On May 5, 2020, Activision Blizzard, Inc. (the “Company”) issued a press release (the “Press Release”) announcing the Company’s financial results for the quarter ended March 31, 2020, which was attached as Exhibit 99.1 to a Current Report on Form 8-K filed by the Company on the same date (the “Original Report”). The Company is filing this Form 8-K/A to correct a table attached to the Press Release that is titled EBITDA and Adjusted EBITDA. Specifically, in the final row of the table, “Change in deferred net revenues and related cost of revenues,” the $171 million shown for the three months ended March 31, 2020, was inadvertently reflected as a positive number rather than a negative number. This also resulted in an incorrect amount being shown for the trailing twelve months ended March 31, 2020. |
