Westport Fuel Systems Inc. (WPRT): fair value, margin of safety and Wheel Score
Consumer Cyclical · Auto - Parts · Canada · Speculative / Distressed
Is WPRT undervalued?
Westport Fuel Systems Inc. (WPRT) closed at 1.79 on 16 Oct 2026, 116% above the GLS average fair value of 0.8288. 1 of the 1 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.
The average is built from just 1 models (DCF) - 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 WPRT 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
Westport Fuel Systems Inc. scores only 2 of 9 on the Piotroski F-score, which fails the Sunday Scan's "6 or more" rule. A reading this low means several of the basic tests - positive earnings, positive operating cash flow, falling debt, no new share issuance - are not met. 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 -83.8%, ROE -89.6%, ROA -65.6% - with debt at 0.07 times equity and negative free cash flow.
Westport Fuel Systems 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 Cummins Westport Inc 51%, IAM 33%, OEM 16% (fiscal year FY2020).
Institutional ownership scores 1/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 2 / 9 | ROIC | -83.8% |
|---|---|---|---|
| GLS Moat | 1.3 / 10 | ROE | -89.6% |
| Debt / equity | 0.07 | ROA | -65.6% |
| Free-cash-flow yield | -40.3% | Payout ratio | 0% |
| Institutions | 1 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 14: Weak
With a Wheel Score of 14 Westport Fuel Systems Inc. sits in the Weak band. The parts - Value 0/25, Health 4/20, Moat 2/15, Premium 5/20, Stability 3/20 - show where: Value (0/25) scores lowest.
Implied volatility is 126%, far above the range the wheel strategy is built for. The premium looks generous; the Wheel Score gives it only 5 of 20 Premium points because moves of that size can blow through any strike. Chain open interest is thin - 559 contracts across every expiry - so fills at a fair price are not guaranteed; a 30-45-day put may not exist at a usable strike.
Volume runs at 63k shares a day on a market cap of $34M, with a beta of 2.12 - 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 3 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 0 / 25 | -116% margin of safety | |
| Health | 4 / 20 | Piotroski 2/9 | |
| Moat | 2 / 15 | moat 1.3/10 | |
| Premium | 5 / 20 | implied volatility 126% | |
| Stability | 3 / 20 | 63k shares/day, $34M cap, beta 2.12 |
