What stands out about T-Mobile US?
- The share price implies shrinking cash flow. At $158.79, TMUS's free cash flow of $15.22 per share would have to shrink 4.0% a year at first, then recover to 2.5% growth by year 10, for this site's DCF (10% discount rate) to match the price. This site's baseline starts at 8% growth, so the price asks for less growth than the baseline. Change the assumptions.
- Misses 1 of the 8 value filters. It fails vs 200-day MA (±12%) (-15.7%); the other 7 pass. See every filter.
- Close to its 52-week low. At $158.79, TMUS is 6.9% above its low of $148.58 and 31.0% below its high of $230.09. See the range.
- Weakest against peers: debt / equity. At 1.61 (peer median 1.03) it ranks 9th of 10 among telecom & communications stocks this site tracks. See the ranking.
- Clears all 4 compounder lenses. It grows profit on little capital, reports real earnings, returns cash to owners and is not priced for perfection on this site's tests. See Compounders at a Fair Price.

What would Buffett & Lynch say?
Buffett's checklist is built around durable, profitable businesses bought at sensible prices, and TMUS doesn't clear enough of it yet. In its favor: TMUS is currently earning a strong return on shareholders' equity, and has kept that profitability up over five years, not just this year, has grown earnings per share at a solid clip over five years, is trading below what a conservative discounted-cash-flow estimate says it's worth - his own "price is what you pay, value is what you get" test, not a fixed multiple ceiling, and trades at a reasonable multiple of owner earnings, his own term for the real cash a business could pay out. Where it comes up short: TMUS carries more debt relative to equity than he typically tolerates, runs thinner pretax margins than he'd like to see, and doesn't cover its interest expense as comfortably as he'd want.

Lynch looked for growth stories that weren't overpriced for that growth, and TMUS falls short of his bar. In its favor: TMUS pays a real dividend, the actual reason he bought slow growers at all, is cheap enough for a business with limited growth ahead of it, and converts earnings into real cash at a reasonable price. Where it comes up short: TMUS isn't even growing at the modest pace he'd expect from a slow grower, and carries more debt than he liked to see, even allowing for the extra room a large, stable business gets.

Quantitative approximations of each investor's documented approach, not endorsed by either investor or their estates - commentary, not this site's actual ranking criteria. Buffett never published a numeric checklist: only 2 of his 8 checks here trace to his own documented concepts ("owner earnings," from his 1986 shareholder letter, and "price is what you pay, value is what you get," his case against fixed P/E/P/B ceilings) - the other 6 (ROE, debt, margins, growth, interest coverage) use commonly-cited thresholds that are not numbers he himself published. The 8 hard filters below (plus the Munger check and Graham margin of safety) are this site's real, mechanical screen and are computed completely independently of the checklists above.
