Purpose of Transaction (Item 4)
SoftBank Group Capital Limited
Item 4 of the Schedule 13D is hereby amended to include the following: On August 6, 2025, Project 4 LLC, Project 6 LLC and Project 9 LLC collectively sold an aggregate of 13,000,000 shares of Common Stock in an unregistered block sale transaction with an unaffiliated broker dealer pursuant to Rule 144 under the Securities Act of 1933, as amended (the "Block Sale") for net proceeds of approximately $3.02 billion, representing approximately 1.16% of the shares of Common Stock outstanding as of July 18, 2025, as reported by the Issuer in its Quarterly Report on Form 10-Q, filed with the Commission on July 23, 2025. Project 4 LLC sold 3,566,400 shares of Common Stock, Project 6 LLC sold 182,043 shares of Common Stock and Project 9 LLC sold 9,251,557 shares of Common Stock. The Block Sale was undertaken as part of the Reporting Persons' normal course evaluation of their investment. Although the Reporting Persons do not have any specific plan or proposal to effect further sales of shares of Common Stock at the time of this filing, the Reporting Persons intend to monitor and evaluate their investment on an ongoing basis. As a result of the Block Sale, the Reporting Persons no longer collectively beneficially own greater than five percent of the number of shares of Common Stock outstanding and therefore this Amendment No. 18 represents the final amendment to the Schedule 13D and the Reporting Persons shall cease to be Reporting Purposes immediately after the filing of this …The first part of Item 4 of the SCHEDULE 13D/A filed 2025-08-08; the filing has the rest

Where this comes from
Anyone who comes to own more than 5% of a class of a listed company's voting shares has to tell the SEC. A holder who may seek to change or influence the company files Schedule 13D, and has to say in Item 4, "Purpose of Transaction", what it intends to do. A holder with no such intent, such as many index and passive funds, may file the shorter Schedule 13G. Both are amended when the stake changes, including when it falls below 5%.
Every row here is one of those filings, linked to the filing itself. Percentages and share counts are exactly as the holder filed them, for the holder the filing names; an amendment showing a lower figure is shown as filed. Item 4 text is quoted word for word. Where a 13D's Item 4 contains a sentence stating a definite intent to influence the company, that sentence is marked and quoted; the page does not describe the holder or its motives beyond the words it filed. Nothing here is investment advice.
