What stands out about Flex?
- The share price implies 26.3% yearly growth. At $76.69, FLEX's free cash flow of $2.21 per share would have to grow 26.3% 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 (29.47) and PEG Ratio < 1.5 (2.43); the other 4 pass and 2 were not evaluated. See every filter.

Is Flex 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) -103.3%
- P/E vs. its own history 29.5x · at/above its priciest point Real range: 7.2x–28.1x 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 · 4.25/5 20 analysts this month: 7 strong buy, 11 buy, 2 hold, 0 sell, 0 strong sell (Finnhub).
- Earnings quality (is the profit real?) Strong · all 5 checks clean Beneish M-score −2.55 · accruals −4.0% of assets · 166% of profit arrived as cash · stock comp 0.5% of revenue · share count −7.4% a year. From the latest 10-K (year to Mar 2026) - see the Earnings Quality Screener for how each check is scored.
- Shareholder yield (cash back to owners) +2.8% net Latest fiscal year (2026): dividends 0.0% + buybacks 3.3% − stock comp 0.5%, as a share of today's market cap. Over 14 years its split-adjusted share count fell 48%. See Shareholder Yield Leaders.
- Capital needed to grow (See's test) $3.01 per $1 of new profit · FlightSafety-like · but only 19% return on capital Operating profit $484M → $1.1B, capital needed $4.1B → $6.0B, 2017–2026 (3-year averages); return on capital now 19% before tax. Buffett's See's Candies needed $0.42 per $1 of new profit, FlightSafety $3.20, a typical grower about $5. See Capital-Light Compounders.

What would Buffett & Lynch say?
Buffett's checklist is built around durable, profitable businesses bought at sensible prices, and FLEX doesn't clear enough of it yet. In its favor: FLEX 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, and earns many times its interest expense, so debt service isn't a worry. Where it comes up short: FLEX isn't clearing the return-on-equity bar he'd want to see right now, carries more debt relative to equity than he typically tolerates, runs thinner pretax margins than he'd like to see, 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% ✓
- Debt/Equity < 0.5 ✕
- Pretax margin > 15% ✕

- Interest coverage > 5x ✓
- Trading below intrinsic value (DCF) ✕

- Bonus: returning capital via buybacks FY2026
Lynch looked for growth stories that weren't overpriced for that growth, and FLEX falls short of his bar. In its favor: FLEX is growing earnings at the steady 10-20% pace of a proper Stalwart. Where it comes up short: FLEX fails his signature PEG test, he'd call this pricey for the growth on offer, carries more debt than he liked to see, even allowing for the extra room a large, stable business gets, is asking investors to pay a steep multiple for that growth, and isn't generating free cash flow to match the growth story.

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.
