Executive Summary

T-Mobile US, Inc. reported strong second-quarter 2026 operating results, with core adjusted EBITDA increasing by 12% and service revenues rising by 9% year over year. Despite these positive fundamentals, the company's stock has experienced a 29% decline over the past year, attributed primarily to merger costs related to UScellular and rising interest rates. The investment-grade bonds offered by TMUS, such as baby bonds and OTC bonds, present less attractive yields and spreads compared to peers, accompanied by elevated duration risk due to rising interest rates. Consequently, one perspective is that current equity or debt investment in TMUS is cautioned against due to unattractive risk/reward ratios and ongoing stock price weakness.

Full Take

The narrative presents a clear divergence between operational strength and market perception regarding the equity and debt instruments of T-Mobile US. The strong growth in core adjusted EBITDA and service revenues establishes a positive underlying business trajectory, yet this performance is overshadowed by external financial pressures—specifically merger liabilities and the macroeconomic impact of rising interest rates—which are clearly priced into the stock's decline. This creates an inherent tension: the company's operational success does not translate directly into attractive investment metrics for shareholders in the current environment. The caution against investing stems from positioning where yields and spreads are less competitive, coupled with sensitivity to rate changes reflected in duration risk. A deeper inquiry must focus on whether the market adequately prices in the long-term sustainable value derived from the revenue growth versus the immediate drags imposed by transaction costs and financing conditions. What is the forward-looking relationship between operational performance and valuation multiples when discounting future cash flows under a rising rate regime?
