SIGA Technologies, Inc. reported a challenging first quarter of 2026, posting a net loss of $3.5 million compared with a loss of $0.4 million a year earlier as revenue declined and costs rose. Total revenue fell to $6.2 million from $7.0 million, mainly because there were no international TPOXX® product sales in 2026 after a $5.8 million shipment to one country in 2025. U.S. revenue was driven by BARDA-related work, including $1.2 million of IV TPOXX® sales and $2.3 million of reimbursed manufacturing technology transfer services.
Operating expenses increased to $11.6 million from $9.3 million, with higher cost of sales tied to technology transfer and IV TPOXX® deliveries, and modestly higher R&D spending related in part to the European mpox referral process. Cash and cash equivalents remained strong at $145.6 million, even after net operating cash use of $8.7 million in the quarter. Stockholders’ equity declined to $151.6 million, largely reflecting a $0.60-per-share special cash dividend of about $43.9 million declared in March 2026 and paid in April.

Product sales and supportive services were $3.5 million, down from $5.8 million, and operating loss increased to $5.3 million.
