Thank you, Karen. Good afternoon. and thank you all for joining us for Amphastar Pharmaceuticals 2023 First Quarter Earnings Call. Joining me today on the call are Bill Peters, CFO and Executive Vice President of Finance; and Tony Marrs, Executive Vice President of Regulatory Affairs and Clinical Operations. For the first quarter of 2023, I am pleased to announce that Amphastar has begun another year on a strong note as our continued execution in our portfolio resulted in $140 million in revenue or a 16% increase on a year-over-year basis. Equally important, our gross profit for the quarter saw an impressive 32% increase on an annualized basis. Once again, we attribute this success to our key, high-margin Primatene MIST, glucagon and epinephrine products, seeing notable increases for sustained growth. Concerning Primatene MIST, in-store sales for the product had a 5% growth compared to the previous quarter. We remain confident that this product is on its path towards $100 million in annualized sales by the end of 2024 as we continue our strategic investment of an additional $2 million to $3 million in marketing spend in 2023. This investment is already in progress, and we are increasing consumer awareness across multiple advertising platforms and remain committed to our physician sampling program. Regarding glucagon, we remain optimistic that with our recent approved capacity increase to which our glucagon output is now doubled, we can continue to meet strong demand. As such, glucagon sales have seen a meaningful 134% increase year-over-year and a 40% increase in sales compared to our previous quarter. For epinephrine, we continue to see significant opportunity for this product due to our previous efforts to increase our capacity to meet the increasing demand despite competitors falling short. To that end, epinephrine sales for our prefilled syringe and multi-dose vials presentation have increased sales by 33% annually. Again, we acknowledge that this increase is due to our ability to fill the gaps left by our other suppliers. We maintain a positive outlook on this product as a growth driver and its potential to remain durable as one of our key, high-margin products for the duration of the year. After covering our key revenue drivers for the quarter, I'd like to shift our focus towards our pending business development opportunity, product launches, pipeline and regulatory activities. As previously communicated, Amphastar has signed an asset purchase agreement to buy BAQSIMI from Lilly. This move aligns with 2 of our strategic goals of expanding our diabetes portfolio which is currently being developed further this year and strengthening our proprietary products portfolio. Fulfilling these 2 strategic goals through BAQSIMI comes with many advantages, primarily the acquisition would add significant scale to Amphastar with our future proprietary product offerings having a solid base of support in the international space. It expands Amphastar's international footprint in 26 countries and strengthens our internal marketing capabilities. Moreover, this transaction aligns with our long-standing disciplined approach to business development while fulfilling strategic goals. Our assessment of the transaction is that it is progressing smoothly, and we anticipate its closure in the second or third quarter this year. With BAQSIMI potentially being part of our portfolio, we are poised to accelerate our long-standing goals of being a leader in the diabetes therapeutic space and a strong contender in the proprietary product market. Moving forward, I'd like to turn our attention to our recent intranasal naloxone approval and launch of a new product in our portfolio. For intranasal naloxone, the product was approved in March with an anticipated launch in the third quarter. While we recognize that the market condition for this product may be more competitive and thus potentially deliver incremental sales, it is important to highlight that the approval included our proprietary intranasal device technology that we have developed and will be manufacturing exclusively at our facilities. This development reinforces our unique vertical integrated business model and strengthens our commitment to innovation and quality. We believe it will enhance our intranasal pipeline and potentially strengthen our commercial capabilities. Nonetheless, the product continues to address a strong community need to address the opioid crisis. In terms of new products added to our portfolio, I am pleased to announce that our regadenoson was recently launched in April. Likewise, we acknowledge this product will be -- enter a more competitive market. Therefore, we expect annualized sales for this product will be incremental compared to our other key revenue drivers. Having covered our business development opportunity with BAQSIMI, product approval and launches, I want to turn our attention to our pipeline and regulatory activity. For our diabetes portfolio, we are on track to file a BLA for insulin aspart, our AMP-004, by the end of 2023 with our goal of achieving interchangeable status. To our teriparatide ANDA or AMP-015, we are on track to respond to the CRL in the second quarter. As for GDUFA date for AMP-002, it remains in the second quarter of this year. As for AMP-007 product, which is our second inhalation ANDA, we expect filing in the third quarter of this year. As for our proprietary product in our pipeline, AMP-019 or intranasal epinephrine, we continue to work with the agency on this product as it continues to actively be developed. And finally, our AMP-008 ANDA product remains on track for a third quarter GDUFA date. As a final point, we'd like to reiterate how excited we are about the upcoming opportunities ahead of us as 2023 has been off to a great start in terms of sales performance, pending GDUFA dates, filings and our diabetes and proprietary product portfolio possibly gaining momentum with BAQSIMI, and our first interchangeable biosimilar insulin BLA being filed at the end of this year. I will now turn the call over to our CFO and Executive Vice President of Finance, Bill Peters, to discuss the first quarter's financial results and provide further details regarding the BAQSIMI transaction.
