Avantor, Inc. (AVTR): fair value, margin of safety and Wheel Score
Healthcare · Medical - Instruments & Supplies · United States · Speculative / Distressed
Is AVTR undervalued?
Avantor, Inc. (AVTR) closed at 16.09 on 16 Oct 2026, close to the GLS average fair value of 17.57 (8.4% below fair value). 2 of the 2 models that produced a number sit above the price, 0 below - the market and our models roughly agree. With little margin of safety either way, the case for or against the stock rests on the quality numbers and the option premium rather than on price.
The average is built from just 2 models (DCF, 10 Cap) - the rest returned nothing because an input they need (dividends, free cash flow, book value) is zero or negative - so treat it with more caution than usual.
The nightly engine files AVTR under Speculative / Distressed - negative earnings or a Piotroski score of 3 or less - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.

Quality and financial health
Avantor, Inc. scores 5 of 9 on the Piotroski F-score: a middling result that falls one point short of the Sunday Scan's "6 or more" rule. Some of the nine tests on profitability, leverage and efficiency are failed, so the accounts are worth a look before selling a put on the name. A GLS Moat score of 1.3/10 is a weak reading: the ten-year history the score grades (revenue, EPS, book value, margins, cash flow, share count, ROIC) has not been steady, so the Moat part of the Wheel Score contributes little.
Returns on capital are thin or negative - ROIC -5.6%, ROE -9.5%, ROA -4.5% - with debt at 0.71 times equity and a free-cash-flow yield of 4.2%.
Avantor, 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 Proprietary Materials And Consumables 52%, Third Party Materials And Consumables 48% (quarter Q2 FY2026).
Institutional ownership scores 10/10, insider activity 10/10 and Congressional trading 5/10 on the GLS smart-money scales; the last recorded insider buy was on 21 Sep 2026.
| Piotroski F-score | 5 / 9 | ROIC | -5.6% |
|---|---|---|---|
| GLS Moat | 1.3 / 10 | ROE | -9.5% |
| Debt / equity | 0.71 | ROA | -4.5% |
| Free-cash-flow yield | 4.2% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 10 · 5 / 10 |
Wheel Score 45: Weak
With a Wheel Score of 45 Avantor, Inc. sits in the Weak band, capped at 45 because the engine files it as Speculative / Distressed. The parts - Value 16/25, Health 11/20, Moat 2/15, Premium 20/20, Stability 20/20 - show where: Moat (2/15) scores lowest.
Implied volatility is 53% 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. The option chain is deep: 134,292 contracts of open interest across all expiries, which means tight fills at most strikes.
Volume runs at 6.0M shares a day on a market cap of $10.9B, with a beta of 0.94; the Stability part of the Wheel Score gives that 20 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 16 / 25 | 8% margin of safety | |
| Health | 11 / 20 | Piotroski 5/9 | |
| Moat | 2 / 15 | moat 1.3/10 | |
| Premium | 20 / 20 | implied volatility 53% | |
| Stability | 20 / 20 | 6.0M shares/day, $10.9B cap, beta 0.94 |
