IDEXX Laboratories, Inc. (IDXX): fair value, margin of safety and Wheel Score
Healthcare · Medical - Diagnostics & Research · United States · High Growth
Is IDXX undervalued?
IDEXX Laboratories, Inc. (IDXX) closed at 547.18 on 16 Oct 2026, 45% above the GLS average fair value of 377.99. 6 of the 8 models that produced a number value the shares below the current price. A gap this wide usually means the market is paying for growth or a story the trailing numbers do not show yet; the models work from filed results, not forecasts, so they are conservative by design.
There is a wide gap between Graham Number (80.28) and GLS Growth (871.08). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.
The nightly engine files IDXX under High Growth: revenue and earnings growing fast enough that the growth-based models carry the valuation.

Quality and financial health
IDEXX Laboratories, Inc. scores 9 of 9 on the Piotroski F-score, the nine yes/no tests of profitability, leverage and efficiency on the latest annual accounts - a strong reading that passes the Sunday Scan's "6 or more" rule with room to spare. A GLS Moat score of 9.7/10 puts IDXX among the more durable businesses we track: over ten years the metrics the score watches (revenue, EPS, book value, margins, cash flow, ROIC) have mostly moved the right way, year after year.
Returns on capital are high - ROIC 39.5%, ROE 66.0%, ROA 31.6% - with debt at 0.67 times equity and a free-cash-flow yield of 2.9%.
IDEXX Laboratories, Inc. pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain. Revenue comes mainly from Product 59%, Service 41% (quarter Q2 FY2026).
Institutional ownership scores 10/10, insider activity 2/10 and Congressional trading 2/10 on the GLS smart-money scales.
| Piotroski F-score | 9 / 9 | ROIC | 39.5% |
|---|---|---|---|
| GLS Moat | 9.7 / 10 | ROE | 66.0% |
| Debt / equity | 0.67 | ROA | 31.6% |
| Free-cash-flow yield | 2.9% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 2 · 2 / 10 |
Wheel Score 70: Good
With a Wheel Score of 70 - the Good band - IDEXX Laboratories, Inc. clears the Sunday Scan's "70 or higher" rule. The parts: Value 0/25, Health 20/20, Moat 15/15, Premium 20/20, Stability 15/20; Value (0/25) scores lowest.
Implied volatility is 41% on the near-the-money contracts 20-60 days out - inside the 35-60% range the Wheel Score pays full marks for: enough premium to be worth selling, not so much that the risk is unpaid. Chain open interest is 3,220 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 545k shares a day on a market cap of $43.1B, with a beta of 1.55 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score gives that 15 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 0 / 25 | -45% margin of safety | |
| Health | 20 / 20 | Piotroski 9/9 | |
| Moat | 15 / 15 | moat 9.7/10 | |
| Premium | 20 / 20 | implied volatility 41% | |
| Stability | 15 / 20 | 545k shares/day, $43.1B cap, beta 1.55 |
