Fair Value models
Bear$5.69Fair Value $9.30Bull$12.37
Price $3.10 · Upside +200.0%
Capped: our models arrive at a very high value here. We deliberately show a more cautious Fair Value.
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models.Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds.Coverage ⓘCoverage = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.
In the last 6 months, no officer or director bought or sold shares on the open market.
Plus 7 other filings such as grants, option exercises or tax withholding. They are not market purchases or sales.
Sales are often planned (taxes, diversification, 10b5-1 plans). Purchases with their own money are seen as the stronger sign. For information only: not part of the quality score or Fair Value.
Growth Quality ⓘGrowth is valuable only when reinvestment earns attractive returns (Aswath Damodaran): sustainable growth depends on return on capital, reinvestment and efficiency. Basis: total company revenue over the periods shown on the cards (3Y/5Y/all years), not per share, so a merger can show up as a growth jump; per-share earnings growth is in the value-creation card.55/100

Revenue growth 3 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year.

What shareholders gained per year (last 5 years) ⓘWhat the business itself delivers per year: earnings growth per share plus the dividend yield. This is what you get IF the market keeps valuing the stock the same way: it contains no assumption about the market changing its mind. Computed per share, so buybacks count and a merger does not pass as growth. For a company that pays no dividend it is pure earnings growth per share. Period: earnings growth per share as CAGR over the last 5 reported fiscal years (annual statements), plus the current dividend yield. The start value is the median of the three years around the start, so a single crisis year (a pandemic or a write-down) does not distort the rate.

Growth Forecast
Little optimism in the price
The price assumes less growth than the company has delivered so far.
What the price assumes ⓘThis turns our valuation around: instead of asking what the share is worth, it asks what growth the current price requires. It uses the cash the company keeps after all spending (free cash flow), the same discount rate as our models, five years of growth, then slowing evenly to 2 % a year by year ten. Compared with the analysts' sales forecasts extended to the same five years (at least three analysts, for context only, it does not enter the Fair Value): within 3 percentage points counts as "in line" (amber), below that little optimism (green), above that a lot of optimism (red).
−10.1%
The company could shrink this much every year for the next five years and today's price would still be justified.

What is a reverse DCF?
A reverse DCF turns the usual calculation around. Instead of deriving a value from assumptions, it takes today's price as given and asks: what free-cash-flow growth would a company have to deliver for exactly this price to be fair? The result is not a forecast but the expectation already priced in. For SIGA Technologies Inc that is -10.1 % per year for five years, then slowing evenly to 2 % by year ten, using the same discount rate (12.6 %) and the same formula as our fair value.
How much growth has SIGA Technologies Inc (SIGA) delivered so far?
Over the past 5 years revenue at SIGA Technologies Inc grew -5.4 % a year. The price currently implies free-cash-flow growth of -10.1 % per year. Comparing the two shows how much confidence is in the price: if it demands more than has been delivered, the business has to accelerate for the maths to work.

The free-cash-flow yield on the price is 19.35 % in the last fiscal year (free cash flow was negative over the last twelve months): that much free cash flow SIGA Technologies Inc produces per unit of market value. When it exceeds the discount rate of our models (12.6 %), the business already earns more than its cost of capital demands, and the price needs little additional growth.

The price is below even our cautious bear case ($5.69). The market is more pessimistic than our downside scenario.
