SIGA Technologies, Inc. (SIGA): fair value, margin of safety and Wheel Score
Ticker symbol SIGA · Healthcare · Drug Manufacturers - Specialty & Generic · United States · Speculative Income
Is SIGA undervalued?
At 3.15 (close of 5 Nov 2026), SIGA trades 64% below the GLS average fair value of 8.74. That average comes from 2 models run on the latest filings, and 2 of them land above the current price. Margins of safety over 30% are the exception rather than the rule across the ~7,400 stocks we value each night, so the number earns SIGA Technologies, Inc. the full Value points in the Wheel Score - and a closer look at what the market is pricing in.
Only 2 of the nine models produced a value (DCF, DDM); 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 SIGA under Speculative - it is losing money or its Piotroski health score is 3 or lower - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan. It also carries the Income tag (Income = a dividend yield of 4% or more).
Nine valuation models for SIGA
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 |
|---|---|---|---|
| DCF | 8.66 | +175% | Present value of the projected free cash flows, discounted at the cost of capital |
| 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 |
| DDM | 8.83 | +180% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | - | - | Earnings power value: current EPS capitalised at 9% with no growth; no value tonight |
| Zombie (liquidation) | 2.68 | -15% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 0.0000 | -100% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is weak: SIGA passes 1 of the nine Piotroski tests. Our scans drop the stock at the health filter; a low score is often the reason a stock looks cheap on the valuation models. The GLS Moat score is 6.4 out of 10: a record that is solid on some of the four parts the score weighs (returns on capital, pricing power, lasting growth, balance sheet) and weaker on others.
Returns on capital are moderate - ROIC 11.7%, ROE 11.7%, ROA 10.6% - with debt at 0.00 times equity and negative free cash flow.
The dividend yield is high at 19.05% (payout ratio -1580%). A yield this size is often the market's way of pricing a risk to the payout, so the health score and cash flow matter more than usual. Revenue comes mainly from Product Sales and Supportive Services 92%, Research and Development 8% (quarter Q2 FY2026).
Institutional ownership scores 6/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 1 / 9 | ROIC | 11.7% |
|---|---|---|---|
| GLS Moat | 6.4 / 10 | ROE | 11.7% |
| Debt / equity | 0.00 | ROA | 10.6% |
| Free-cash-flow yield | -9.1% | Payout ratio | -1580% |
| Institutions | 6 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 35: Weak
SIGA scores 35 out of 100 on the Wheel Score, in the Weak band (under 50): it fails filter 2, a real business, not a gamble - speculative (a loss, or a weak Piotroski score); and filter 4, financially healthy - Piotroski 1/9 (under 6); and filter 8, big enough - market cap $226M (under $1.0B); and filter 9, not a penny stock - price 3.15 (under $5), and the parts are thin too - value strong, premium good, moat good, health weak, red flags weak, option trading weak, stability fair. The score is not a judgement on the company; it says the price, quality and premium do not line up for selling puts on it today.
Implied volatility is 79% on the near-the-money contracts 20-60 days out - above the 60% top of the sweet spot. It still passes the 25-80% filter, but the Wheel Score rewards it less because volatility this high usually comes with a reason. Chain open interest is thin - 1,852 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 313k shares a day on a market cap of $226M, with a beta of 1.02; the Stability part of the Wheel Score rates that fair.
| Filter | Wheel Trade Filter | Result | Detail |
|---|---|---|---|
| 1 | Options that actually trade | Passes | Listed options with 1,000+ contracts of open interest and 100+ traded a day |
| 2 | A real business, not a gamble | Fails | speculative (a loss, or a weak Piotroski score) |
| 3 | Below fair value | Passes | Trading below the nine-model average fair value (margin of safety above 0) |
| 4 | Financially healthy | Fails | Piotroski 1/9 (under 6) |
| 5 | Can repay its debt | Passes | Long-term debt repaid from 3 years of operating cash flow or less (6 for real estate and utilities; banks and insurers are not judged on it) |
| 6 | No serious red flags | Passes | Red Flags score 60 or more out of 100 (earnings, margins, debt, analysts, filings and price checked the same way for every stock) |
| 7 | A premium worth selling | Passes | Implied volatility 25-80% (enough premium, not a lottery ticket) |
| 8 | Big enough | Fails | market cap $226M (under $1.0B) |
| 9 | Not a penny stock | Fails | price 3.15 (under $5) |
| How it ranks | Rating | From | |
|---|---|---|---|
| Value | Strong | 64% below fair value | |
| Premium | Good | implied volatility 79% | |
| Moat | Good | moat 6.4/10 | |
| Health | Weak | Piotroski 1/9 | |
| Red Flags | Weak | Red Flags score 62/100 | |
| Option trading | Weak | 159 contracts a day, 1,852 open interest | |
| Stability | Fair | beta 1.02, $226M company |
