First quarter earnings spark fresh look at SIGA Technologies

SIGA Technologies (SIGA) has drawn fresh attention after reporting first quarter 2026 results, with revenue of US$6.24 million and a net loss of US$3.45 million, compared with the same period a year earlier.

The 1-day share price return of 2.11% and 7-day move down 13.12% leave SIGA trading at US$4.17, with the 1-year total shareholder return also down 21.30%, suggesting momentum has been fading despite previous multi year resilience.

With first quarter figures showing lower revenue and a wider loss, and the stock down over multiple timeframes yet trading at an estimated 11% discount to intrinsic value, is this weakness a potential entry point or is the market already pricing in future growth?

Preferred P/E of 14.8x: Is it justified?

On a P/E of 14.8x compared with a last close of $4.17, SIGA screens as good value against peers, even though the share price has been under pressure.

The P/E multiple compares what investors are currently paying for each dollar of earnings. For a commercial stage pharmaceutical company with high quality earnings, this is a commonly used yardstick because it links directly to current profitability.

Here, SIGA trades on a P/E of 14.8x while the peer average sits at 48.6x, indicating the stock is priced well below what similar companies command. The estimated fair P/E of 49.7x is also far above the current level, suggesting a valuation gap that the market could move toward if expectations align more closely with those implied by this fair ratio.

Result: Price-to-earnings of 14.8x (UNDERVALUED)

However, you still need to weigh concentration in a single product and the recent share price slide of 33.5% year to date as potential pressure points.

Another way to look at value

While the current P/E of 14.8x suggests SIGA looks cheap against peers and its fair ratio, the SWS DCF model paints a more measured picture. With an estimated future cash flow value of $4.69 versus a share price of $4.17, the discount sits at roughly 11%. That is a smaller margin of safety. Which signal do you treat as the anchor?
