Mobile’s $85 Billion Debt Load Won’t Feel the Fed’s Rate Hike the Way Wall Street Thinks
T-Mobile's $86.9B debt is mostly fixed-rate, limiting Fed rate hike impact. Only $1B is floating. Q2 EBITDA grew 12%. 2026 free cash flow guidance raised to $18.8B. Stock fell 5.57% post-Fed hike. Verizon and AT&T have similar debt structures.

Background
The article analyzes how the Federal Reserve's September rate hike affects T‑Mobile's massive debt portfolio and stock price.
