T-Mobile US Inc. (TMUS) — RQD Stock Rating Cockpit

Per the Roarable RQD rating, TMUS scores 53 out of 100, a D+ grade labeled "Roarable Sell — Weak Fundamentals / Trim." The five pillars are: Fundamental Cash Engine at 14 out of 20 (ROIC 10.7%; FCF yield 11.53%); Whale 13F Flow at 6 out of 20 (institutional accumulation and options positioning); Insider Conviction at 16 out of 20 (SEC Form 4 and Congressional PTR cluster flow); Macro Regime Fit at 10 out of 20 (Beta 1.03; sector sensitivity); and Forensic Balance Sheet at 7 out of 20 (Altman Z 1.7; Piotroski F 6/9; Debt/Equity 1.37).

For a prospective investor, the strongest pillar is insider conviction, and the cash-generation metrics are respectable, with an 11.53% FCF yield providing a meaningful valuation cushion. The weakest pillars are institutional flow and balance sheet forensics. An Altman Z of 1.7 sits in a range that warrants caution, and a Debt/Equity of 1.37 means leverage is a material consideration. The beta of 1.03 indicates the stock tracks broad market moves closely, so macro conditions will influence it. Valuation (P/E 14.2 TTM, forward P/E 13.2) appears modest relative to earnings, but the RQD framework weights balance-sheet and flow signals heavily enough to produce a sell-leaning verdict. The upside case rests on cash conversion and insider confidence; the downside case rests on leverage and weak institutional support.

Per the market data, operating margin is 20.7%, net margin 12.4%, and gross margin 0%. Per the Roarable RQD rating, ROIC is 10.7%, the Altman Z-Score is 1.7, and the Piotroski F-Score is 6 out of 9. Debt/Equity is 1.37 per the RQD rating; reported debt rose from $74,197.0M in FY 2024 to $81,147.0M in FY 2025 per the SEC financials, while cash moved from $5,409.0M to $5,598.0M over the same period.
