Amazon (NASDAQ: AMZN) disclosed:

On March 9, 2022, the Board of Directors also authorized the Company to repurchase up to $10 billion of the Company’s common stock. The program allows the Company to repurchase its shares opportunistically from time to time when it believes that doing so would enhance long-term shareholder value. The repurchase authorization does not have a fixed expiration. Purchases may be effected through one or more open market transactions, privately negotiated transactions, transactions structured through investment banking institutions, or a combination of the foregoing. This stock repurchase authorization replaces the previous $5 billion stock repurchase authorization, approved by the Board of Directors in 2016, under which the Company had repurchased $2.12 billion of its shares.
