Dividend coverage (FY2025)

Exceeded at least one reported measure. In FY2025, SIGA's dividend exceeded at least one reported measure of what it earned or generated (earnings payout 185%, operating-cash-flow payout 99%). A payout above 100% in one year is not necessarily unsustainable, but it is not fully covered by that measure.

  • Earnings payout185% dividends / net income
  • Operating-cash-flow payout99% dividends / operating cash flow — capital spending was not reported, so this does not subtract it

Coverage derived from reported SEC EDGAR XBRL figures for FY2025 (dividends paid vs. net income and free cash flow, same fiscal year). This describes PAST coverage for one fiscal year — it does not predict whether a dividend will be maintained, raised, or cut, and a one-year payout ratio can be distorted by non-recurring items.

How SIGA TECHNOLOGIES INC looks technically

SIGA TECHNOLOGIES INC (SIGA) is trading 41.4% below its 200-day average, the long-term trend line — a long-term downtrend. Its 50-day average crossed below its 200-day average about 164 trading days ago — a "death cross", a bearish long-term signal. A strong downtrend is in place — ADX, a 0–100 trend-strength gauge, is 32, with sellers in control. Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 44, neither overbought (above 70) nor oversold (below 30). MACD, a trend-momentum gauge, turned bullish about 8 trading days ago (its momentum flipped positive). It made a new 20-day low about 10 trading days ago. It is 67.8% below its highest point of the past year. Trading volume is unusually light — only about 48% of its 30-day average.

Position in its 14-day rangeit is trading in the upper half of its 14-day range ($2.83 to $3.19) — its "stochastic" reading is 58 out of 100, where 0 would mean closing exactly at the 14-session low and 100 exactly at the high. This measures WHERE the price sits inside its recent range, which is a different question from the RSI beside it: RSI is a momentum gauge, measuring how FAST the price has been moving, so a stock can drift quietly to the bottom of its range with an ordinary RSI, or fall sharply and still sit in the middle.

Vs the Ichimoku cloudtrading 18% below the Ichimoku cloud — a band drawn from where its own highs and lows sat up to 2026-07-20 and projected forward over today's price, the side traders read as an established downtrend, with the band above acting as the level that would have to be cleared.

A level is a price this company reversed or paused at more than once — they describe past behaviour, not a forecast of where the price will go.

Wave structure

Its recent swings can be read as a five-part downward sequence — what Elliott-wave chartists call an impulse — now in leg 4 of five, a pullback against that direction.

This labelling fails — stops being a possible reading at all — if it closes above $4.09.

This is one of several labellings that fit the same swings, so treat it as a reading rather than the reading. It was chosen from 2 labellings that survived the rules, counting shorter readings of the same bars.

On past moves of this shape the leg has usually ended somewhere between $3.29 and $3.81 — that is where it has tended to end if the count holds, not a forecast of where the price goes.

Alternate reading: The same swings also read as a completed three-part correction, which fails on a close below $2.83.

This labelling was already in place when we began recording count changes on 2026-08-13, so how long it has stood is not something we can say yet.

["Regulatory uncertainty: EMA's Committee for Medicinal Products for Human Use (CHMP) initiated a referral procedure in July 2025 questioning the effectiveness of Tecovirimat-SIGA for mpox treatment, with potential for withdrawal of the mpox indication and potential suspension or withdrawal of the overall marketing authorization.","Revenue concentration and dependency: The company's sales are primarily concentrated to U.S. and international governments through procurement contracts, creating dependency on government demand and budget allocation for Strategic Stockpile acquisitions.","Macroeconomic and supply chain risk: Tariffs and trade policy volatility could materially increase manufacturing costs, particularly for IV TPOXX® which relies on European raw materials, adversely impacting operating results."]

Only open-market purchases (SEC code P) and sales (code S) are counted here. Option exercises, vesting/awards, gifts, and shares withheld for taxes are excluded — they are compensation or mechanical, not open-market conviction. Sales may be planned and non-discretionary (e.g. a Rule 10b5-1 plan) and are not necessarily bearish; open-market buying is not a recommendation to buy. Informational only — not financial advice.
