On 29 July 2025, Deutsche Telekom AG and three wholly-owned subsidiaries, each deemed a 10% owner and director-by-deputization of T-Mobile US (TMUS), filed a Form 4 disclosing open-market dispositions executed under a Rule 10b5-1 trading plan adopted 13 Mar 2025.

No derivative securities were involved. The modest sale represents routine liquidity management by the controlling shareholder; Deutsche Telekom retains a dominant equity position in TMUS.
T-Mobile US, Inc. (TMUS) filed a Form 144 indicating an insider’s intent to sell 12,300 common shares on or about 29 Jul 2025. The planned sale has an aggregate market value of ≈ $2.96 million, implying a reference price near $241 per share. The shares represent ~0.001% of the 1.13 billion shares outstanding, so dilution impact is negligible.
The securities were acquired through restricted-stock vestings on 15 Feb 2022 (6,372 shares) and 15 Feb 2024 (5,928 shares) and will be sold through Fidelity Brokerage Services on Nasdaq. No prior sales were reported in the past three months. The filer certifies no undisclosed material adverse information and compliance with Rule 10b5-1 if a trading plan is in place.
- Form 144 serves only as advance notice; it does not guarantee execution or disclose sale price.
- Given the modest size relative to market capitalization, the filing is unlikely to be financially material but may signal personal portfolio rebalancing by the insider.
