Pulmatrix, Inc. (PULM): fair value, margin of safety and Wheel Score
Healthcare · Biotechnology · United States · Speculative / Distressed
Is PULM undervalued?
Pulmatrix, Inc. (PULM) closed at 1.37 on 16 Oct 2026, 30% above the GLS average fair value of 1.05. Only 0 of the 1 models that produced a number value the shares above the current price. The margin of safety is negative, so the stock fails the "below fair value" rule of the Sunday Scan; a premium of this size is common for companies whose growth the models are conservative about.
Only 1 of the nine models produced a value (DCF); the others need a dividend, positive free cash flow or positive book value the company does not have yet, so the average rests on a narrow base.
The nightly engine files PULM 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.
Nine valuation models for PULM
Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.
| Model | Value | vs price | What it measures |

| Graham Number | - | - | The most a defensive investor pays for the earnings and book value per share; no value tonight |
| Graham Growth | - | - | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields; no value tonight |
| Lynch | - | - | EPS × the earnings growth rate (PEG of 1), growth capped at 25%; no value tonight |
| GLS Growth | - | - | EPS compounded ten years at the blended growth rate, discounted back at 15% a year; no value tonight |
| 10 Cap | - | - | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10%; no value tonight |
| Payback Time | - | - | Eight years of compounded free cash flow: the price at which the business pays for itself; no value tonight |

Quality and financial health
Financial health is weak: PULM passes 1 of the nine Piotroski tests. Our screens drop the stock at the health rule; a low score is often the reason a stock looks cheap on the valuation models. The GLS Moat score is low at 1.5 out of 10, which says the ten-year record of revenue, earnings, margins and returns on capital has been inconsistent - growth and shocks rather than steady compounding.
Returns on capital are thin or negative - ROIC -135.5%, ROE -135.5%, ROA -124.7% - with debt at 0.00 times equity and negative free cash flow.
Pulmatrix, 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 Toxicology Study Costs 100% (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 | 1 / 9 | ROIC | -135.5% |
|---|---|---|---|
| GLS Moat | 1.5 / 10 | ROE | -135.5% |
| Debt / equity | 0.00 | ROA | -124.7% |
| Free-cash-flow yield | -78.1% | Payout ratio | 0% |
| Institutions | 1 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 8: No options
PULM has no listed options in the nightly snapshot, so there is nothing to sell and the stock cannot be wheeled however good the business; the Wheel Score is capped at 39 and shown as "No options" (8 here). The valuation and quality numbers still apply to owning the shares outright.
Volume runs at 10k shares a day on a market cap of $5M, with a beta of 1.93 - 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 4 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 0 / 25 | -30% margin of safety | |
| Health | 2 / 20 | Piotroski 1/9 | |
| Moat | 2 / 15 | moat 1.5/10 | |
| Premium | 0 / 20 | no option data | |
| Stability | 4 / 20 | 10k shares/day, $5M cap, beta 1.93 |
