T-Mobile US, Inc. – Leading US Wireless Provider in Growth

Brief Summary for Investors: T-Mobile US is one of the largest wireless providers in the US with over 108 million customers. The company is benefiting greatly from the successful integration of Sprint and the expansion of its 5G network.

Development The share price showed a clear upward trend from 2020 to the end of 2022, driven by the successful completion of the Sprint acquisition, cost synergies, and the aggressive expansion of the 5G network advantage. Strong operating performance, particularly the significant increase in free cash flow and EPS in 2023, continued this trend and drove the share price to an all-time high of €233.55 by December 2024. The recent price correction in the first half of 2025 is related to a general re-rating of growth stocks and potential economic concerns, despite continued solid operating results.

Opportunities:

• 5G Leadership: The continued monetization of the superior 5G network through network differentiation and the development of new revenue streams (e.g., fixed wireless access internet) offers significant upside potential.
• Synergy Realization: The full exploitation of cost and revenue synergies from the Sprint acquisition continues to improve profitability and free cash flow generation.
• Market Share Gain: The aggressive marketing strategy and attractive pricing packages continue to enable the acquisition of customers from competitors.

Risks:

• High Debt: The debt-to-equity ratio (debt-to-equity of ~2.48) remains elevated despite strong cash flow, making the company vulnerable to interest rate changes.
• Intense Competition: The price war in the saturated US mobile market with Verizon and AT&T could put pressure on margins.
• Economic Vulnerability: An economic slowdown could make customer acquisition more difficult and increase loan losses in the prepaid segment.

Additional Notes: Political transactions show mixed signals, with purchases and sales of similar sizes. A director and the CEO recently sold shares due to option exercise, but this is not necessarily a negative signal given the high remaining stake.

Conclusion: T-Mobile continues to operate financially strong with robust revenue growth, high profitability, and exceptional free cash flow generation. Short-term share price volatility reflects macroeconomic concerns, not a deterioration in operating fundamentals. The long-term investment thesis remains intact, based on network leadership and continued profitability improvement. The main risk remains the high level of debt in a rising interest rate environment.
