With that, I will turn the call over to Diem Nguyen, Chief Executive Officer of SIGA. Diem?

Good afternoon, everyone, and thank you for joining today's call and a review of our business results for the second 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. At the midpoint of 2025, I'm pleased to share that SIGA continues to make steady progress as we advance our strategic initiatives. The evolving global landscape calls for agility and focus, and our team remains deeply committed to strengthening our role in the global health security and delivering enduring value to our shareholders. In the second quarter of this year, we achieved 2 important positive results, significant product revenues and a significant increase to the development funding under the BARDA 19C contract. In the quarter, product revenues totaled approximately $79 million, comprising of $53 million of oral TPOXX and $26 million of IV TPOXX delivered to the U.S. Strategic National Stockpile, or SNS. These deliveries fulfilled the $70 million of orders outstanding at year-end 2024. At the end of the second quarter, there were approximately $26 million of remaining outstanding orders from the U.S. government. This outstanding balance relates to the March 2025 U.S. government exercise of an option under the 19C contract to procure an additional $26 million of IV TPOXX. We note this option exercised during our last investor call and expect to deliver this order in 2026. Also during this quarter, we received commitments from the U.S. government to provide $27 million of incremental development funding. This increase in development funding occurred in 2 buckets. In April, the government modified the 19C contract by adding $14 million in funding to support manufacturing activities, which we expect to occur over the next 2…

Thanks, Diem. As noted earlier in the call, SIGA's product sales for the 3 months ended June 30, 2025, were $79 million. Product sales for the quarter comprised $53 million of oral TPOXX sales and $26 million of IV TPOXX sales to the U.S. government under the 19C BARDA contract. For the 6 months ended June 30, 2025, product sales are $85 million. In addition to product sales, the company has research and development revenues of approximately $2 million and $3 million for the 3 and 6 months ended June 30, 2025, respectively. As a supplemental note, there are $26 million of remaining outstanding orders as of June 30. This amount reflects the $26 million IV TPOXX order received in the first quarter of this year under the 19C contract, which is targeted for delivery in 2026. Pretax operating income for the quarter, which excludes interest income and taxes, is approximately $46 million. For the 6 months ended June 30, 2025, pretax operating income is approximately $43 million. Net income for the quarter as well as the 6 months ended June 30, 2025, is approximately $35 million. In turn, fully diluted income per share for the 3 and 6 months ended June 30, 2025, is $0.49 per share. The company continues to maintain a strong balance sheet. At June 30, 2025, the company had a cash balance of approximately $182 million and no debt. This concludes the financial update. At this point, I will turn the call back to Diem.

Thank you, Dan. With that, we would like to open the call up for questions.

[Operator Instructions] And your first question comes from the line of Jyoti Prakash from Edison Group.

First of all, congratulations on the strong sales performance in the quarter. My first question is related to the $13 million BARDA funding for the pediatric program. How do you plan to deploy these funds? And if you can comment on the likely trial design and the data required for a possible approval?

Jyoti, nice to hear from you, and thanks so much for this question. This is a really important program for SIGA because we believe it is important to be able to develop a formulation to protect a very vulnerable population. BARDA has been very supportive of this program throughout the development process, and this additional funding reemphasizes the importance of tecovirimat to the U.S. government. This investment will fund development activities up to regulatory filings. As it relates to the study design, by the way of the background, in 2023, we initiated and concluded a Phase I study that evaluated an oral suspension formulation prototype in healthy adults for the development of pediatric powder for oral suspension formulation. That study looked at a range of factors with a primary goal to understand how the drug in this formulation behaves in the body after a single dose compared to TPOXX capsule. While we're now preparing for the follow-up trial, which will evaluate a refined formulation designed to deliver tecovirimat dose appropriate for pediatric use, it will be a single-dose crossover study that also examines how different meal types affect absorption. This ensures that children receive a safe and effective dose that mirrors adult exposure levels.

My second question relates to your international growth efforts. You mentioned the CHMP requesting additional data from the mpox trial. And if you look at the recent quarters, you've had strong order demand and you have delivered significant orders. So I just want to understand this new data request, how does this impact your plans for international growth expansion -- growth and expansion?

This is Dan. I'll take that question. Maybe as a starting point, the background is that we took over the international promotion and marketing from Meridian last summer. Over the past year, we have been spending considerable time strengthening and building relationships with current and potential customers around the globe. And all this effort has really been centered on expanding our international business and ensuring countries are prepared in case of a smallpox outbreak. As you're aware, there's a lot of preparation and groundwork that's part of the international effort. Given the current geopolitical instability and the stockpile strategies for these individual countries, we do believe that we are building an international business that has significant potential. In terms of timing of future sales activity, we expect international orders to continue to be lumpy. With that context, I would highlight that we have sold $135 million of oral TPOXX to 30 countries since 2020. And we do believe that, that shows the depth and the scope of the international opportunity.

Thanks for the clarification, Dan. Moving on to the U.S. market. You talked briefly about the RFP process and your ongoing conversations. But do you have any further clarity on the timelines for the RFP? And secondly, assuming if the RFP is received in the second half of the year, what would be the typical lead time between order receipt and delivery?

This is Dan. I'll also respond to that question. I think there's 2 components in there, and it's mostly sort of focused on some of the mechanics. We had some prepared remarks on this. But as you can imagine, it's difficult for us to speculate on the exact timing and form of the U.S. government RFP. What we can say is that we do believe that we have seen recent confirmation of the U.S. government's commitment to biodefense this quarter with the combination of the deliveries of TPOXX, which have been substantial and the 2 commitments for development funding that we've talked about both in our prepared remarks as well as our press release, that development funding adding up to $27 million, which is a meaningful number. With that backdrop, our focus does remain on fostering the strong partnership that we've had for a very long time, really over a decade. And this ongoing partnership plays a vital role in supporting what we believe is national security and public health efforts. And we really think that's valuable. It's worth a lot. So overall, we do believe we're well positioned to engage with the U.S. government on RFP when they are ready. In terms of process, I think there was a part of your question about just sort of timing on process. I would say that there are many variables. But in short, maybe I could just sort of at least use the 2018 process that was -- these are long-dated contracts, and that was the last contract we dealt with the United States government that lasted until recently in terms of orders. In that process, in 2018, there's an RFP that was put out. Now granted, in this situation, the RFP could be both open competition or it could be sole source justification. So a variety of different forms. But in 2018, there's an RFP that was put out. And then after the RFP, we would enter a negotiation process. In 2018, from start to finish in terms of negotiation that took 6 months. Having said that, the time frame could vary in either direction given the administration change. So we would be as efficient as possible. We've gone through many procurement processes. And so we will be very efficient and we are prepared. And we're not aware of any impediments to the negotiation process going much faster than 6 months if the U.S. government desires it.

And I have one final question, and this is related to the preclinical monoclonal antibody program, which was licensed in late 2024. Just wanted to understand what's the current status of the program? And what are your plans for clinical development?

Thank you, Jyoti. This is Diem. I'll take that. First and foremost, I would just begin by saying that we remain quite enthusiastic about the opportunity to expand our pipeline with this portfolio of preclinical fully human monoclonal antibodies, which can be used as a potential treatment for a broad range of orthopoxviruses, both as a therapeutic as well as a prophylactic measure. These monoclonals have demonstrated promise in preclinical models. And we are looking to potentially execute on programs to determine the benefits of using this as a stand-alone treatment or in combination with TPOXX. We're currently working through our process to determine the best path forward for these assets from a development and manufacturing perspective, and we'll keep you apprised with our plans as we progress.

[Operator Instructions] And there are no further questions at this time. I will now hand the call back to Diem Nguyen for any closing remarks.

Thank you. I'd like to first by thanking everyone here for making the time to join today's call and for your ongoing interest in SIGA. We look forward to speaking to you again on our third quarter call. Have a good evening.

And this concludes today's call. Thank you for participating. You may now disconnect.
