Thank you, Haywood. Good afternoon, everyone. We appreciate you joining the call. Starting on Slide 10, I'll open my remarks with the key messages I'd like you to take away from our call today. First, there were several clear positives in the quarter. We followed through on the critical initiatives we discussed on our last call, by closing the sale of our Travel Health business to Bavarian Nordic securing a $120 million order from the U.S. government for ACAM2000 and successfully completing an amendment to our secured credit facility that extends its maturity to May 2025. We also saw accelerating momentum in sales of NARCAN Nasal Spray, driven by continued strength in the U.S. public interest market and in Canada. These trends provide a favorable tailwind as we prepare for the near-term launch of our over-the-counter product. And we delivered strong revenue, which exceeded our prior guidance as well as strong adjusted EBITDA. Second, our decision to deemphasize growth in CDMO is both immediate and near-term implications. While we are committed to serving our existing customers, the change in growth expectations is the principal driver behind the CDMO asset impairment charge reported in the second quarter. Additionally, we are significantly reducing the operational footprint of our Bayview facility, which is a major contributor to the over $100 million of annualized savings we announced earlier today. Third, while we remain confident in the long-term prospects for our medical countermeasures business, based on recent dialogue with the U.S. government, we have lowered expectations for 2023 revenue in our anthrax and smallpox franchises. The approval of CYFENDUS is a clear positive and sets the stage for continued procurement by the U.S. government for this product. Given this transition, procurement in 2023 is expected to be reduced, and we anticipate the funding for increased levels of procurement will be available as soon as 2024. In addition, we understand that while TEMBEXA remains a core piece of the U.S. government's smallpox preparedness strategy, the next procurement of TEMBEXA is being deferred into future periods. Finally, this morning's announcement reflects decisive action to further streamline our cost structure and accelerate our return to profitability. In addition to the changes I just mentioned at Bayview, we are reducing operations in our Camden and Rockville sites in response to changes in the volumes of U.S. government procurement of our smallpox vaccine, while maintaining the manufacturing infrastructure critical to respond to the government's evolving needs for preparedness against public health threats. And we are also reducing related support across our general and administrative functions. While there will be some savings realized this year, we anticipate over $100 million of savings beginning in 2024. With that, let's turn to the numbers. As indicated on Slides 11, 12 and 13, highlights in the second quarter include total revenues of $338 million, an increase over the prior year, driven primarily by higher ACAM2000 sales due to timing and NARCAN sales from the U.S. public interest market and the retail market in Canada. And as expected, our key profitability measures increased versus the prior year, with adjusted EBITDA of $56 million and adjusted net loss of $54 million. Diving deeper into the quarterly revenues, important items include Anthrax MCM sales of $21 million lower than the prior year due to timing of deliveries of CYFENDUS and BioThrax to the U.S. government's Strategic National Stockpile, offset by increased sales of Anthrasil. NARCAN sales of $134 million higher than the prior year, demonstrating the continuing strength and durability of this product driven by consistent demand from the U.S. public interest channel and the growing market in Canada. Smallpox MCM sales of $124 million higher due to the exercise and full delivery during the quarter of the $120 million option by the U.S. government to procure ACAM2000. Other product sales of $23 million, level with the prior year as higher RSDL sales were partially offset by lower BAT sales. And combined CDMO service and lease revenues of $29 million higher than the prior year due primarily to work at the Canton site for a CDMO customer as well as the resolution of a customer's outstanding contractual obligation. Turning to operating expenses. Cost of product sales in the quarter of $135 million higher than the prior year due primarily to higher product sales of ACAM2000 and NARCAN. Cost of CDMO of $56 million lower than the prior year due primarily to reduced production across the CDMO network, partially offset by higher costs at the Camden site, reflecting additional investments in quality improvement initiatives. R&D expense of $26 million lower than the prior year due primarily to the divestiture of our CHIKV program, which was a significant contributor to the prior year period; and SG&A spend of $92 million higher than the prior year, largely due to higher professional services fees supporting transformation activities. Finally, we incurred a noncash impairment charge of $307 million in the quarter, related to fixed assets at our CDMO sites in Maryland. With that, let's move to Slide 14 and review segment performance during the quarter. In the Products segment, revenues were $302 million, an increase from the prior year driven by NARCAN and ACAM2000 and adjusted gross margin was $170 million or 56% an increase over the prior year, reflecting the impact of higher sales volume and a more favorable product mix. As for the Services segment, revenues were $29 million, an increase from the prior year, and adjusted gross margin was negative $27 million, an improvement versus the prior year, driven primarily by onetime costs in the prior year period that did not recur, partially offset by additional investments in quality enhancement initiatives at the Canton facility. Moving on to Slide 15. I'll touch on select balance sheet and cash flow highlights. We ended the second quarter with $89 million in cash down sequentially from March 31, primarily due to debt repayments made in connection with the amendment and maturity extension of our existing senior secured credit facility. Operating cash flow was negative in the quarter, and capital expenditures in the period were $13 million. And as of June 30, 2023, our net debt position was $821 million. During the quarter, we initiated our at-the-market or ATM equity offering program. For the quarter, we sold 1.1 million shares of our common stock for gross proceeds of $9.1 million, representing an average price of $8.22 per share. Turning to guidance. Please see Slides 16 and 17. As announced in our press release this evening, we are updating our guidance for full year 2023 as follows: Total revenues of $1 billion to $1.1 billion, a decrease of $100 million at the midpoint from prior guidance as the ongoing strength in NARCAN is being offset by reduced expectations across our other products and services. We're forecasting Anthrax MCM sales of $200 million to $220 million, a decrease of $60 million at the midpoint. With the recent FDA approval of CYFENDUS secured, we anticipate continued procurement by the U.S. government for this product. We expect smallpox MCM sales of $180 million to $200 million, a reduction of $55 million at the midpoint. Based on our latest discussions with HHS, we expect the U.S. government will defer additional purchases of TEMBEXA for now as the U.S. government determines the appropriate volume and cadence of purchases going forward. We're forecasting NARCAN Nasal Spray sales of $425 million to $445 million, an increase of $65 million at the midpoint over the prior guidance, primarily reflecting robust demand from the U.S. public interest channel and from Canada. As well as taking into account our expectations regarding the launch of NARCAN OTC. We expect other product sales of $100 million to $120 million, a reduction of $20 million at the midpoint, primarily reflecting the reduction of revenue expectations for Trobigard, our auto-injector product. We're forecasting CDMO services revenue of $60 million to $80 million, a reduction of $30 million at the midpoint, primarily reflecting lower anticipated sales as the Camden site continues to focus on quality and remediation efforts to scale back up operationally. Shifting to profitability metrics. We're forecasting adjusted EBITDA of $50 million to $100 million, a decrease of $50 million at the midpoint from the prior guidance range, primarily reflecting the impact of lower total revenues, partially offset by the impact of the facility and other cost actions discussed earlier. We anticipate adjusted net loss of $195 million to $145 million, a reduction of $110 million at the midpoint. And finally, we're forecasting adjusted gross margin of 36% to 39%, a reduction of 300 basis points at the midpoint from the prior guidance range, primarily reflecting the impact of lower revenue, volume and mix. As to the quarter, we're guiding to revenues of $210 million to $250 million in the third quarter, further emphasizing our anticipation that revenues and profits in 2023 will be more heavily weighted towards the second half of the year. To conclude, please turn to Slide 18 for summary comments. Our results in the second quarter were strong, and we delivered on a variety of important milestones. We are adapting our business to focus on products while continuing to serve our existing customers. We will continue to strengthen our quality and compliance across the organization. And we are taking decisive action to better align our costs with our customer needs while continuing to solidify our financial position. That completes my prepared remarks, and I'll now turn the call over to the operator so that we can start the question-and-answer session. Operator?
