Good afternoon, everyone, and thank you for joining today's call and review of our business results for the first quarter of 2025. I am joined by Dan Luckshire, our Chief Financial Officer, and we appreciate this opportunity to provide an update on our company. After the update, we'll be happy to answer your questions. I'm pleased to share that SIGA has continued its momentum from 2024 into 2025, and we expect many bright spots ahead. SIGA has made steady progress on its key initiatives, taking thoughtful and proactive steps to reinforce our position as a leader in global health security and to deliver long-term value to our shareholders. While we are encouraged by this progress, we remain focused on navigating the evolving landscape and staying disciplined in our approach to drive sustained performance. In the first quarter, product revenues were approximately $6 million, which is attributable to a sale to a repeat international customer in a different geographical region from where we made an $11 million sale in the fourth quarter. This highlights the broadened scope of our international business. Since we assumed responsibility for international marketing for Meridian Medical Technologies in June 2024, we have been strengthening our relationships with existing and prospective customers and engaging in productive discussions on health security and stockpiling. For those keeping track, we now have regulatory approvals for TPOXX in the U.S., Canada, Europe, the U.K. and most recently in Japan. We expect the $6 million international sale in the first quarter to be the start of substantial product sales over the next few months. On the U.S. side of our business, as of the end of 2024, we had about $70 million of outstanding TPOXX orders for delivery to the U.S. Strategic National Stockpile, or SNS, of which approximately $53 million of oral TPOXX and approximately $9 million of IV TPOXX were delivered in April. Additional amounts of IV TPOXX are expected to be delivered by the end of third quarter this year. Notably, in March, the U.S. government exercised its option under the current 19C contract to procure an additional $26 million of IV TPOXX, which we expect to be delivered in 2026. Also, the government modified our current agreement to add $14 million of funding to support manufacturing activities, which will occur over the next 2 to 3 years. We believe the U.S. government's decision to exercise the IV procurement option and to provide funding support for IV manufacturing activities underscores the critical importance of maintaining a full complement of TPOXX formulations in the stockpile as treatment options for smallpox. The IV formulation is an important alternative for those who are unable to swallow capsules. Given the severity of this disease, we are encouraged by the U.S. government's ongoing recognition of the critical role of antivirals play in safeguarding national security, and we are proud to support its commitment in strengthening preparedness. Looking forward, as we look beyond our current 19C contract, we remain committed to working alongside the U.S. government to establish a new comprehensive long-term agreement that reflects the value of TPOXX both today and in the future, and importantly, one that would further reinforce the nation's preparedness against bioterrorism and advance our shared objective of enhancing global health security and public health. Switching gears, we continue to advance our late-stage pipeline with TPOXX postexposure prophylaxis program for smallpox or PEP. We continue to collaborate with the CDC in consultation with FDA to complete the analysis of samples collected to support the study's immunogenicity objective. The FDA has actually engaged with us in this program, providing real-time guidance in support of our ongoing efforts. We believe the agency's valuable feedback has strengthened our plan and will help facilitate the regulatory process. The CDC is now finalizing its approach and preparing to analyze our samples with the work expected to be completed during the fourth quarter. We are now targeting an FDA submission of PEP indication for the first half of 2026. At an early stage in our pipeline with PEP, our pediatric program is also progressing well. This effort, in partnership with BARDA, is important as it will address critical unmet need for children too small for the current oral formulation of TPOXX. We have manufactured the clinical trial material and preparing to submit an IND in the second half of this year with clinical trial target to begin shortly thereafter. As we continue advancing in our strategic initiatives, we remain focused on delivering value to our shareholders. In that spirit, our Board of Directors recently declared a special cash dividend of $0.60 per share to be paid on May 15. This is our fourth consecutive year of paying special cash dividend and reflects the strength of the balance sheet and the confidence that our Board and management have in the future of the company. As we look ahead to the remainder of the year, we remain committed to maintaining a strong financial foundation and executing on our strategic priorities with discipline. We continue to focus on key areas that have proven successful for us: one, continuing our partnership with the U.S. government; two, advancing regulatory approvals of TPOXX in new indications; three, cultivating strategic partnerships to expand global access to TPOXX; and four, leveraging our capabilities to move into complementary therapeutic areas. Antivirals play a vital role together with vaccines by treating patients who have not been vaccinated or who did not benefit from vaccination. As the risk of emerging infectious disease and bioterrorism threats grow, the dual-pronged approach comprised of vaccines and antivirals become -- is increasingly important. In a comprehensive preparedness plan, strategic stockpiling of antivirals along vaccines is critical to ensuring rapid coordinated response in times of crisis. Importantly, given our long-standing partnership and history of collaboration between SIGA and the U.S. government as well as the government's demonstrated commitment to a proactive and robust biodefense strategy, we remain focused on addressing an RFP when issued and subsequently finalizing an agreement. In summary, SIGA has a clear vision for the future. With a sound strategy, disciplined capital management, a valuable TPOXX franchise and a proven track record, we are well positioned to drive progress. We are resolute in executing our plans with precision and urgency while staying committed to making impactful contributions to global health security and creating value for our shareholders. With that, I'll turn it over to Dan to review the financial results in more detail. Dan?
