This Item 6 is hereby amended and supplemented as follows:

Early Unwind of the Forward Contract

On February 22, 2023, Deutsche Telekom entered into an early unwind agreement (the “Unwind Agreement”) that amended the terms of the Forward Contract to provide for the early cash settlement of the forward purchase by Deutsche Telekom of up to 20,000,000 shares of Common Stock, which is the aggregate number of shares of Common Stock covered by the Forward Contract (the "Forward Shares"). Under the terms of the Unwind Agreement, the unaffiliated counterparty was obligated to sell up to all of the Forward Shares during the 60 trading days beginning on the date of the Unwind Agreement (the “Unwind Period”).

On March 31, 2023, the Unwind Period ended and all of the Forward Shares were sold pursuant to the Unwind Agreement. On April 4, 2023, DT made the settlement payment and the Forward Contract terminated in its entirety. The settlement payment amount paid by DT was determined based on a volume-weighted average price at which the Forward Shares were sold during the Unwind Period of $143.27, and included accrued and unpaid interest and other charges.
