Key Business Developments

Japan's Pharmaceuticals and Medical Devices Agency approved TPOXX for treatment of orthopoxviruses

SIGA assumed responsibility for promoting TPOXX outside the U.S. from Meridian Medical Technologies

Licensed a portfolio of preclinical monoclonal antibodies from Vanderbilt University for potential treatment of orthopoxviruses

Post-Exposure Prophylaxis (PEP) Program progressing with FDA submission targeted for early 2026

TPOXX Clinical Trials for Mpox

Results showed potential benefits for patients treated early or with severe disease

Management noted trials enrolled patients at later stages (5.9-8 days after symptom onset)

Emphasized TPOXX's mechanism works best when administered early in infection

Future Outlook

Working with new U.S. administration on a potential new TPOXX contract in 2025

Continuing to build international sales and marketing infrastructure

Anticipate making capital management decisions in Q2 2025 (potential special dividend)
