Very good question. Looks like they bought $44 billion in 6 months and had about $30 billion left in what was authorized, so raising it a bit "makes sense" if they wanted to continue at that clip (which almost feels like indication that management expects their stock to be somewhat undervalued over the next year)
> During the six months ended March 30, 2024, the Company repurchased 248 million shares of its common stock for $44.0 billion. The Company’s share repurchase program does not obligate the Company to acquire a minimum amount of shares. Under the program, shares may be repurchased in privately negotiated or open market transactions, including under plans complying with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).
> In addition to its contractual cash requirements, the Company has an authorized share repurchase program, under which the remaining availability was $30.1 billion as of March 30, 2024. On May 2, 2024, the Company announced the Board of Directors had authorized an additional program to repurchase up to $110 billion of the Company’s common stock. The programs do not obligate the Company to acquire a minimum amount of shares.
