Deutsche Telekom AG and four wholly owned subsidiaries — all more than 10% owners and directors-by-deputization of T-Mobile US, Inc. (NYSE: TMUS) — filed a Form 4 disclosing open-market sales of common stock executed between 9 July 2025 and 11 July 2025.
- Total shares sold: 209,070.
- Price range (weighted-average prices): $226.76 – $234.85 per share.
- Proceeds (rough estimate): about $48 million, using the weighted-average prices reported for each tranche.
- Residual ownership: 647,381,484 TMUS shares held directly after the final sale on 11 July 2025.
- Ownership dilution: the divestiture represents roughly 0.03% of the reporting group’s TMUS stake (209,070 ÷ 647.6 million).
- Plan-based trading: all transactions were executed under a Rule 10b5-1 plan adopted 13 March 2025, indicating the sales were pre-scheduled.
The filing shows no derivative activity and no change in the group’s director status. Given the tiny percentage sold relative to the controlling position, the move appears to be routine liquidity management rather than a strategic reduction. However, it confirms ongoing supply from the majority shareholder, a factor investors may monitor for future volume and price dynamics.
On July 2, 2025, T-Mobile US, Inc. (NASDAQ: TMUS) filed a Form 8-K disclosing that it and its wholly-owned subsidiary, T-Mobile USA, Inc., have extended the expiration date of their Exchange Offers and related Consent Solicitations for all outstanding senior notes of United States Cellular Corporation (USCC).

No other terms of the Exchange Offers have been changed.
The Exchange Offers were first launched on May 23, 2025 and are being conducted under an effective Registration Statement on Form S-4 (No. 333-287414). They form an integral part of the Securities Purchase Agreement dated May 24, 2024, under which T-Mobile intends to acquire substantially all of USCC’s wireless operations and select spectrum assets. Exhibit 99.1 contains the press release announcing the extension; no additional financial statements were filed.
Key takeaways for investors:
- The one-month extension modestly lengthens the transaction timeline but does not affect pricing, consideration, or covenants.
- No incremental financial data, guidance changes, or regulatory concerns were disclosed in the filing.
- The Exchange Offers remain critical to closing the USCC asset purchase, but management signals the process is continuing without material revision.
Overall, the event is operational rather than financial in nature and is expected to have a neutral near-term impact on TMUS equity or debt valuation unless additional delays occur.
