Thanks, Paul. I'll begin by expanding on the 8-K filing that Joe mentioned earlier in the call. Today, we announced that we have entered into a forbearance agreement with our lenders through April 30, while we continue our initiatives to increase operational performance, improve working capital and pursue certain product or asset sales. As Joe highlighted, the transformation of the company will be a multiyear process with the near term being heavily focused on strengthening our credit profile and capital structure. All decisions will be made through the lens of improving overall performance and enhancing enterprise value. While the details of the sale processes are confidential, we seek to generate additional cash proceeds that can be used to further reduce our debt and enable credit improvement as we transform the business. The forbearance agreement provides further evidence of the constructive relationship we continue to have with our lenders, and we look forward to providing further updates on our capital structure in the future. During the fourth quarter, Emergent made great progress improving the fundamentals of our business and advancing our core products. We continue to reduce costs and right-size operations in order to de-risk the business and strengthen our financial position. These actions reflect our sharpened strategic focus and the ongoing transformation of our business as we concentrate on enhancing revenue, improving operational efficiencies and reducing debt. Throughout 2023, we maintained a very positive relationship with the U.S. Government and other key medical countermeasure customers. As a result, we achieved significant contract awards that reinforce the value of our products as an essential part of the government's preparedness planning, which continues to evolve. Having said that, as I'll expand on in a few minutes, our 2024 forecast has more variability than in years past. In October, we appointed two pharmaceutical industry veterans to the Board, Neal Fowler and Don DeGolyer, who bring more than 70 years of combined biopharmaceutical industry and sales experience. We believe their expertise will be valuable as we continue to grow NARCAN sales, advance our other products and partner with governments to prepare for public health threats. Let me walk through some of the progress we're making across our core products as highlighted on Slide 10. As you just heard from Paul, after many years of research and development and in partnership with the FDA, we officially launched NARCAN Nasal Spray as an over-the-counter opioid overdose reversal treatment in August last year. This is a monumental milestone for our company that expanded access to naloxone. Throughout the year, we've been able to meet the ever increasing demand for NARCAN, resulting in expanded access and broader awareness of NARCAN and underpinned by strong support from federal and state programs. As we look ahead, we expect NARCAN Nasal Spray to remain a key contributor to our growth in the near term. We also secured several important contract wins last year across our other core products, including a new $379.6 million U.S. Department of Defense contract for RSDL, a $75 million option to extend Emergent's existing contract for CYFENDUS, and a 10-year contract with BARDA valued at $704 million for the development and manufacturing scale up and procurement of Ebanga, our licensed treatment for Ebola virus. And we've already announced a contract award for 2024 with the U.S. Department of Defense valued at $235.8 million to supply BioThrax, a form of the anthrax vaccine. This new contract award is a testament to the importance of our medical countermeasure portfolio to the U.S. Government's preparedness and response plans. Finally, we achieved many important R&D milestones this year. In July 2023, we received U.S. FDA approval of CYFENDUS, a two-dose anthrax vaccine for post-exposure prophylactic use. We received Health Canada regulatory approvals for our ACAM2000 vaccine and TEMBEXA drug that each address smallpox. We also submitted a supplemental BLA to the FDA that would extend ACAM2000's indication to include immunization against the Mpox virus. We expect to hear back from the FDA by the third quarter of this year. These contracts and development advances reflect the U.S. Government's need to maintain a high level of preparedness against a wide range of potential threats that frankly are increasing as events unfold worldwide. Emergent is uniquely positioned to deliver these products in an efficient and cost-effective manner, and we are committed to supporting the U.S. Government's efforts to address emerging infectious diseases and strengthen future preparedness. In 2023, we also completed several initiatives to improve our credit profile and derisk our capital structure. As you know, we divested our travel health business, generating up to $380 million of proceeds, extended the maturity of our secured credit facility to May 2025, implemented actions to save over $160 million of annualized operating expense and announced a strategic shift to focus on our products business. Turning to our results. We had solid revenue in the quarter, which led to full year 2023 revenue in line with the midpoint of our guidance range provided on November 8. Adjusted EBITDA was impacted by revenue timing and one-time write offs, which I'll provide further detail on shortly. As indicated on Slide 11, highlights from the fourth quarter include: total revenues of $277 million, driven by NARCAN and CYFENDUS; total segment adjusted gross margin of $86 million; adjusted EBITDA in the quarter of $3.4 million; and adjusted net loss of negative $40 million. Diving deeper into the quarterly revenues. Important items on Slide 12 include: Anthrax MCM sales of $112 million, driven by CYFENDUS deliveries to the U.S. Government's Strategic National Stockpile, including initial shipments under the $75 million contract option provided by BARDA that we announced on November 28. NARCAN sales of $111 million demonstrating the continued strength and durability of this product driven by consistent demand from the U.S. public interest channel and the growing market in Canada. Revenue in the quarter also includes contributions from the launch of OTC NARCAN into retail channels. Smallpox MCM sales of $12 million driven by VIGIV. Other product sales of $15 million primarily related to RSDL and BAT. And total bioservices revenues $21 million reflecting our continued transition to focus on existing customers. Turning to operating expenses on Slide 13. Cost of Commercial Product sales in the quarter was $50 million, driven by strong sales of NARCAN. Cost of MCM Product sales in the quarter was $97 million, driven primarily by CYFENDUS sales volume and other medical countermeasure products as well as an increase to inventory write-offs. Cost of bioservices of $38 million reflecting actions taken to improve profitability. R&D expense of $29 million which includes one-time costs associated with project terminations. And SG&A spend of $90 million including expenses supporting key NARCAN initiatives, reduced by expenses -- offset by reduced expenses related to restructuring initiatives. With that, let's move to Slide 14 and review segment performance during the quarter. Note that beginning with the fourth quarter of 2023, we now report our results in three segments: Commercial Products, MCM Products and Services. This change will provide increased transparency for investors as we move forward. In the Commercial segment, revenues were $111 million, comprised entirely of NARCAN, and segment adjusted gross margin was $61 million or 55%. In the MCM segment, revenues were $138 million, driven by anthrax, RSDL and BAT. The segment adjusted gross margin was $42 million or 30%. As for the Services segment, revenues were $21 million and segment adjusted gross margin was negative $17 million. Shifting to Slide 15, I'll highlight our 2023 full year performance. Full year revenue was $1.05 billion, in line with the midpoint of our previously provided guidance. Full year total segment adjusted gross margin was $336 million or 33% at the low end of our guidance range. Full year adjusted EBITDA was negative $22 million, also at the low end of our range. And adjusted net loss was negative $319 million. Transitioning to Slide 16, I'll highlight the 2023 full year costs. Cost of Commercial Products was $210 million, driven by the continued strength of NARCAN Nasal Spray in the existing channels, as well as the launch of NARCAN Nasal Spray over the counter in late August 2023. Cost of MCM Products was $306 million, which was influenced by sales volume, product mix and unabsorbed manufacturing overhead costs. Cost of bioservices was $190 million, heavily influenced by our cost structure in the first half of 2023, which was a primary focus of the cost reduction actions we announced on August 8. R&D expense was $97 million including the chikungunya cost prior to the divestiture of the Travel Health business. SG&A was $368 million, which included additional marketing expenses related to NARCAN, legal fees and restructuring expenses. Moving to Slide 17. Commercial Products segment revenue for the full year was $497 million, up roughly $100 million versus the prior year, with a segment adjusted gross margin of 58%, in line with the prior year and reflecting pricing reductions we took midyear on NARCAN Nasal Spray to improve access and affordability. Full year MCM product segment revenue was $447 million and segment adjusted gross margin was 34%. The margin for the MCM business was influenced by sales volume, product mix, cost absorption and inventory write offs. And the Services segment had revenue of $79 million and segment adjusted gross margin of negative $103 million, influenced by sales volume and costs in the first half of 2023 prior to our restructuring efforts announced on August 8. I'll now turn to Slide 18 and touch on select balance sheet and cash flow highlights. We ended 2023 with $112 million in cash and $192 million of total liquidity, including availability under our revolving credit facility. The increase in cash and liquidity versus the prior quarter was due to sales timing and collection of accounts receivable. Operating cash flow in the full year was negative, but in the second half of 2023, it was positive $92 million. Capital expenditures were $52 million in 2023. And as of December 31, our net debt position was $757 million. Turning to 2024 guidance, please see Slide 19. As announced in our press release this evening, we are providing guidance for full year 2024 as follows: Total revenues of $900 million to $1.1 billion. Commercial Product sales of $460 million to $500 million, as we expect continued strong demand for NARCAN in the U.S. public interest channel in Canada combined with further growth with OTC NARCAN in the retail channel. We're forecasting MCM product sales of $340 million to $490 million. As we previously noted, now that CYFENDUS is a fully licensed, the primary procurement will transition from BARDA to the Strategic National Stockpile. We recognize that the U.S. Government is balancing multiple threat preparedness needs with the level of funding provided by Congress and that this fact could impact the magnitude and timing of, in particular, anthrax procurements in the near term, even as this potential threat remains a top strategic priority. As a result, we've provided a wide range of potential outcomes for the MCM segment. We continue to engage with our U.S. Government stakeholders to improve the procurement visibility that is needed to support this critical capability for the benefit of all United States citizen. As a final note on the MCM Products, we continue to see stable, consistent sales to the U.S. Government under the long-term contracts we have in place for our plasma and chemical decontamination products, VIGIV, BAT and RSDL. We're forecasting Services segment revenue of $70 million to $80 million, reflecting our commitment to serving our existing customers. Shifting to profitability metrics. We're forecasting adjusted EBITDA of $50 million to $100 million, reflecting the impact of our 2023 cost reduction actions, our capacity utilization profile and the range of revenue expectations across our segments. For the full year of 2024, we're forecasting total segment adjusted gross margin of 40% to 45%, an increase over the 2023 level, primarily reflecting the full year impact of our profitability improvement efforts. Finally, we're forecasting Q1 revenue in a range of $200 million to $250 million. That's all for the financial update. I'll now turn the call back over to Joe for some final thoughts.
