What stands out about AMETEK?
- The share price implies 22.2% yearly growth. At $238.82, AME's free cash flow of $8.02 per share would have to grow 22.2% a year, fading to 2.5% by year 10, for this site's DCF (10% discount rate) to match the price. This site's baseline starts at 8%, so the price asks for more growth than the baseline. Change the assumptions.
- Misses 2 of the 8 value filters. It fails Trailing P/E < 25 (34.48) and PEG Ratio < 1.5 (3.81); the other 4 pass and 2 were not evaluated. See every filter.

What would Buffett & Lynch say?
Buffett's checklist is built around durable, profitable businesses bought at sensible prices, and AME doesn't clear enough of it yet. In its favor: AME is currently earning a strong return on shareholders' equity, and has kept that profitability up over five years, not just this year, carries a conservative amount of debt relative to equity, converts sales into profit at healthy margins, has grown earnings per share at a solid clip over five years, and earns many times its interest expense, so debt service isn't a worry. Where it comes up short: AME is trading above what a conservative discounted-cash-flow estimate says it's worth right now, and trades rich relative to owner earnings, the real cash the business could pay out.

- ROE (5yr avg) > 11% ✓

- Bonus: returning capital via buybacks FY2025
Lynch looked for growth stories that weren't overpriced for that growth, and AME falls short of his bar. In its favor: AME is growing earnings at the steady 10-20% pace of a proper Stalwart, isn't over-leveraged for a company of its type, and is backing its growth up with real free cash flow. Where it comes up short: AME fails his signature PEG test, he'd call this pricey for the growth on offer, and is asking investors to pay a steep multiple for that growth.

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.
