Good afternoon, everyone, and thank you for joining today's call and review of our business results for the fourth quarter and full-year of 2023. I am joined by Dan Luckshire, our Chief Financial Officer; and we're pleased to have this opportunity to provide an update to our shareholders. After the update, we'll be happy to answer any other questions. I'd like to begin by recognizing the work and contributions of Phil Gomez, who served as SIGA's CEO for the seven years. Phil was instrumental in transforming our company into a more commercial organization, with sales in over 25 countries and securing key regulatory approvals for our TPOXX franchise. On behalf of our team, I want to thank Phil for his many contributions to making SIGA the strong company it is today. On a personal note, I'm excited to join SIGA and take on the role of CEO. Having spent nearly three decades focused on addressing unmet needs in health care, I look forward to building on SIGA's success and driving greater growth for the benefit of our patients, customers and shareholders. I have a deep-seated passion for scientific advancement and innovation, as well as an extensive experience leading successful multibillion-dollar commercial organization. I'm extremely excited to leverage this experience to help fulfill SIGA's potential and have our essential therapies available worldwide. Although this is only my 6th week with the company, I'm pleased to share my belief in SIGA's bright future. This belief has been grounded for the following: First, SIGA has strong business fundamentals. It is a highly profitable company with a management team that has deep expertise in commercial activities, antiviral R&D and government relations. And the company has built and maintained a fully integrated U.S.-based operational supply chain. This is a distinguishing asset for our customers. Second, TPOXX is a foundational product franchise that has a track record of securing multiyear government contracts, which have totaled over $1 billion in the past 10-years. Again, this is a point of distinction and speaks to the significant value of TPOXX. Third, SIGA has achieved best-in-class financial performance. Our average annual pretax operating income over the past 4 years has been $75 million. These results have been achieved, while maintaining a strong balance sheet. Fourth, SIGA has attractive growth opportunity. Let me just mention a few. In the near term, SIGA has the potential to expand the indications of TPOXX, to include post-exposure prophylaxis, which we like to call PEP and mpox. I'll provide an update on these programs a little later in these remarks. Also in the near-term, SIGA has the opportunity to expand geographically and work with governments across the world, to fully embrace stockpiling and preparedness for a full range of orthopox virus risk. We want to ensure governments have a modernized view of the risk and the tools for protection against orthopox viruses. And thinking more broadly, SIGA has strong antiviral and government procurement capabilities. We believe these capabilities are best-in-class that we can leverage to move into complementary therapeutic areas with similar points of patient care. Importantly, all of this has reinforced TPOXX’ leadership among officious disease common measures. SIGA's expertise and experience in commercial execution, R&D innovation and government contracting enables us to support the highest level of public and individual safety. As a result of these four critical factors, I believe SIGA is well-positioned for further innovation, strong business performance and attractive value creation for our shareholders. Now turning to our financial results. I am very pleased to report that we finished the year strong. Full-year 2023 product revenues of $131 million, are the highest amounts achieved over the past five years. This reflects a 51% increase over 2022. Approximately $116 million of the full year product revenues were achieved in the fourth quarter, coming from a diversity of sources including the U.S. Strategic National Stockpile or the SNS, the U.S. Department of Defense and five international governments. Pretax operating income was approximately $84 million in 2023, a 96% increase over 2022. This is a testament to the strength of the SIGA team, the value of our franchise and the resilience of our company. Dan will provide more details on these results shortly. Additionally, in 2023, we spent $43 million on capital management through a combination of special cash dividend and share buyback. And I'm pleased to announce that our Board of Directors has declared a special dividend of $0.60 per share to be paid in April. This represents a 33% increase over the special dividend, we paid in June of 2023. This demonstrates the financial strength of our company and the confidence the Board and the management team, have in our future. Our proven track record, coupled with the potential of a new long-term contract with SNS provides both a compelling and attractive backdrop for our company in both the short and longer term. Looking forward, we plan on continuing to invest to grow our business. While maintaining a balanced and disciplined capital allocation approach, with the goal of delivering strong long-term revenues and earnings growth and creating value for our shareholders. And now I would like to talk about PEP and mpox programs. With regard to PEP, I will start by recapping what was reported on the last investor call. Based on the studies and trials that have been conducted, we believe TPOXX' benefits patients in a prophylactic situation. The FDA has not asked for any additional studies to prove the efficacy of TPOXX for PEP, but has asked for extended safety data in humans for treatment for 28 days. We have completed this requirement and the data is consistent with prior safety studies. It is important to emphasize the clinical trial results do not show any drug-related serious adverse events. Consistent with TPOXX' existing strong safety profile. In addition to the safety trial, we have completed a Jynneos TPOXX immunogenicity trial, solely to evaluate as TPOXX has an impact on vaccine immune response. Because in the event of an outbreak, TPOXX treatment would likely to be used in combination with a small pox vaccine. In the preliminary analysis of the data from the immunogenicity trial, consistent with what we expected, the results did not show a meaningful difference between immunogenicity of those who receive the Jynneos vaccine, while on placebo, compared to those that received the Jynneos vaccine, while on TPOXX. However, as mentioned previously, the results indicated that the number of volunteers who had measurable immune response to the Jynneos vaccine, in both the placebo and TPOXX group was lower than expected. Given these results, the data deemed difficult to assess for the non-inferior statistical determination, which was necessary for the primary endpoint as originally planned in the study. On the last investor call, we also reported that a subset of the Jynneos and TPOXX samples from the immunogenicity trial were sent to our colleagues at the CDC, who performed their validated print analysis on them. These samples show the expected immune responses. As such, we are now working on getting the entire set of the samples reanalyze, given the challenges associated with the prior analysis conducted by our CRO vendor. We believe these preliminary CDC analyses provide a potential path forward despite the unexpected nature of the prior results. As such, in parallel, we are working towards a supplemental NDA submission within the next 12 months. We are grateful to our colleagues at the CDC for this collaboration and efficient path forward. We believe this is the best course of action, in terms of getting timely data from the immunogenicity trial, and the FDA agrees as they have been briefed on our plans and have not voiced any objections. But as a final comment on the PEP program, I want to emphasize that the immunogenicity analysis are not about the efficacy or safety of TPOXX nor are they about TPOXX' impact on those individuals who are showing an immune response. Rather, the relevance of the immunogenicity study is that in the case of an orthopox virus epidemic, be it mpox or smallpox, use of TPOXX with the vaccine for PEP, will be important to reduce the morbidity and mortality of the population without sacrificing patient safety. Now I would like to shift gears and provide a quick update on the current mpox trials involving TPOXX, which includes 4 randomized controlled trials, as well as multiple observational studies. These studies continue to enroll patients and collect data to provide some specific data points. In Africa, as of February, NIAID PALM trial being conducted in the DRC, has enrolled approximately 425 patients. A large increase from the 314 patients, noted in our last call. In the NIAID STOMP trial, as of February, there were 267 patients, which is also a substantial increase from the 157 patients noted in our last call. These increases in patient numbers demonstrate that the case counts continue to accumulate especially in Africa. Importantly, they also provide a glimpse. Some would say a warning into the overall global health risk posed by orthopox viruses. As such, we are working closely with the NIH and other health agencies on randomized clinical trial to demonstrate whether TPOXX is safe and effective for treating mpox in Africa, the U.S. and other parts of the world to achieve the best possible outcome for mpox patients from a public health perspective. I would like to remind, however, TPOXX is approved for smallpox, mpox, cowpox and vaccinia complications in Europe and in the U.K. At this point, I would like to turn the call over to Dan for the financial update.
