SIGA Technologies, Inc. (SIGA) Cash Flow Statement

In 2025Q1, SIGA reported -$0.4M net income yet produced +$7.1M in operating cash flow, a sign-flipped divergence suggesting non-cash charges or working capital releases cushioned the reported loss. Conversely, 2024Q1 and 2024Q3 saw positive net income of $10.3M and $1.3M paired with negative OCF of -$6.1M and -$7.4M, indicating cash was absorbed by receivables or inventory before collections landed. This bidirectional gap across ten quarters implies SIGA's cash generation is dominated by working capital timing rather than underlying earnings power, warranting scrutiny of any single-quarter profitability print.

The cumulative free cash burn of -$35.7M across 2025Q3–2026Q1 contrasts sharply with +$126.4M in FCF generated across 2024Q4–2025Q2, highlighting a binary pattern tied to contract milestone recognition. The 2026Q2 FCF margin of 15.9% on $41.0M revenue compares unfavorably to 2025Q2's 77.8% on $81.1M, suggesting unit economics on recent deliveries may be weaker or cost absorption less favorable. Without visibility into SIGA's contracted backlog, the sustainability of the 2026Q2 recovery remains uncertain.

The -$17.7M working capital consumption in 2024Q1 followed by a +$10.4M release in 2024Q2 demonstrates the classic contract cycle: cash tied up in receivables during delivery, then collected post-shipment. The -$19.6M and -$5.5M drag across 2025Q4 and 2026Q1, followed by only +$4.5M recovery in 2026Q2, suggests SIGA's receivables conversion has slowed relative to prior cycles — collections are not keeping pace with earlier patterns. Investors should monitor whether the 2026Q2 working capital release fully reverses the preceding two quarters' consumption or represents a permanent lengthening of the cash cycle.

The three lump-sum distributions totaling ~$129M appear to follow peak-collection quarters rather than a calendar-driven schedule, implying management releases cash opportunistically after large contract receipts materialize. Critically, 2026Q2's $43.3M dividend exceeded that quarter's $6.5M operating cash flow by nearly 7x, meaning the payout was funded from accumulated balance-sheet reserves rather than current-period cash generation. This approach provides flexibility but creates distribution unpredictability — shareholders cannot rely on consistent returns absent visibility into SIGA's contracted pipeline.
