What stands out about Teledyne?
- The share price implies 17.6% yearly growth. At $620.47, TDY's free cash flow of $24.90 per share would have to grow 17.6% 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.

Is Teledyne undervalued? The value diligence check
Every value-investing signal this site computes for this stock, gathered in one place: the same real numbers from the tools below, not a new score.
- Margin of safety (DCF) -45.9%
- P/E vs. its own history 29.2x · near the cheap end Real range: 23.6x–43.3x over 5 years (net income per diluted share from each fiscal year's 10-K, paired with the real closing price at that fiscal year-end).
- Wall St. analyst rating Buy · 3.88/5 17 analysts this month: 4 strong buy, 7 buy, 6 hold, 0 sell, 0 strong sell (Finnhub).

- Shareholder yield (cash back to owners) 1.4% gross Latest fiscal year (2025): dividends 0.0% + buybacks 1.4%. Stock comp is not reported in its filings, so no net figure. Over 14 years its split-adjusted share count rose 27%. See Shareholder Yield Leaders.

What would Buffett & Lynch say?
Buffett's checklist is built around durable, profitable businesses bought at sensible prices, and TDY doesn't clear enough of it yet. In its favor: TDY 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, earns many times its interest expense, so debt service isn't a worry, 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: TDY isn't clearing the return-on-equity bar he'd want to see right now, and its five-year average return on equity falls short too, so this isn't just a one-off dip, and is trading above what a conservative discounted-cash-flow estimate says it's worth right now.

- ROE (5yr avg) > 11% ✕

- Bonus: returning capital via buybacks FY2025
Lynch looked for growth stories that weren't overpriced for that growth, and TDY falls short of his bar. In its favor: TDY 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: TDY 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.
