(a)-(b) The information contained in the cover pages of this Schedule 13D and the information set forth in Item 6 of this Schedule 13D is incorporated herein by reference.

To the best knowledge of the Reporting Persons, Michaela Klitsch has the sole power to vote or direct the vote or dispose or direct the disposition of all of the shares of Common Stock beneficially owned by her.

Item 6.

Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

This Item 6 is hereby amended and supplemented as follows:

On May 21, 2021, Deutsche Telekom entered into a forward purchase contract (the “Forward Contract”) with an unaffiliated counterparty covering up to a maximum of 20,000,000 shares of Common Stock (the “Shares”).

The Forward Contract provides for cash settlement at its expiration on June 21, 2024. However, Deutsche Telekom retains the right, subject to certain conditions, to elect physical settlement in whole or in part. Under certain circumstances, the counterparty has the right to physically settle all or part of the Forward Contract notwithstanding Deutsche Telekom’s election to cash settle.

Under the terms of the Forward Contract, Deutsche Telekom will be obligated to make quarterly payments to the counterparty equal to the sum of the daily interest amounts for each day in the preceding period calculated on the basis of a floating rate times the purchase price for the Shares.

If the Forward Contract is settled in whole or in part in cash, if the settlement price (based on the average daily volume weighted price for transactions in the Shares over a period of 20 trading days (or 45 trading days if Deutsche Telekom so elects and the relevant conditions are satisfied) exceeds the purchase price, the counterparty will pay the difference amount to Deutsche Telekom. If the settlement price is lower than the purchase price, Deutsche Telekom will pay the difference amount to the counterparty. To the extent that physical settlement is applicable to all or any portion of the Forward Contract, Deutsche Telekom will pay the purchase price per Share times the number of Shares to which physical settlement is applicable to the counterparty and the counterparty will deliver the applicable number of Shares to Deutsche Telekom.

Deutsche Telekom will not have the right to vote, or any investment power as to, the Shares covered by the Forward Contract unless and until it takes physical delivery of any such Shares on the settlement date in accordance with the terms of the Forward Contract.

On August 24, 2021, the counterparty completed its initial hedge, and the number of Shares covered by the Forward Contract has been fixed at 20,000,000. The purchase price for the Shares is $142.88.
