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…

Thank you, Dan. Sales for the first quarter increased 16% to $140 million from $120.4 million in the previous year's period. Glucagon sales increased 134% to $25.7 million from $11 million due to market demand. Epinephrine sales grew to $20.1 million from $15.2 million, while lidocaine sales grew 29% to $13.6 million from $10.6 million in the first quarter of 2023 on both strong unit demand. Primatene MIST saw sales declined 5% to $23.5 million from $24.7 million but we saw in-store growth of 5% in the quarter. So we believe this is a timing issue. Phytonadione sales dropped to $7.7 million from $10.5 million as a new supplier entered the market. Sales of other products in our finished pharmaceutical product portfolio grew 13% due to higher unit volumes of dextrose and a full quarter of sales of Ganirelix and vasopressin, which were both launched in 2022. Insulin API sales grew to $4 million from $3.8 million in the prior year, primarily due to the timing of shipments. Gross margins increased 53% of sales from 46% due to increased sales of high-margin products such as glucagon and epinephrine as well as sales of Ganirelix and vasopressin. These trends were partially offset by higher labor and material costs. Selling, distribution and marketing expenses increased to $7.1 million from $5.5 million, primarily due to increased advertising costs. General and administrative spending increased to $13.5 million from $12.5 million due to increased legal costs related to our planned acquisition of BAQSIMI. Research and development expenditures increased to $19.8 million from $16.2 million due to increased labor costs, increased expenses related to clinical trials for our insulin and inhalation programs and purchases of materials and components for our pipeline. We anticipate these expenditures will continue this upward trend in the coming quarters. Nonoperating income…

[Operator Instructions] And we'll take our first question from Tim Chiang from Capital One.

Maybe you could talk a little bit about glucagon. Obviously, you did really well in the quarter with that product. How sustainable do you think the glucagon sales run rate will be this year? Could you make some comments about that? I mean is this a $25 million to $30 million a quarter type product for you?

Yes. We believe that this is going to be the run rate for the rest of the year. And just keep in mind that we were able to build up inventory of the product going into the quarter knowing that we are going to have increased demand this quarter, but we did not have the doubling of the capacity online until the end of the quarter. So our operations did a great job of getting the inventory built and readying for the quarter. And now that we have that additional capacity, we're able to meet that demand on an ongoing basis.

And maybe just 1 follow-up. 53%, 54% gross margins you guys did this quarter. Is that sort of also an adequate run rate going forward for gross margins?

Yes. So for the year, we had said that we'd be relatively flat from last year, but it's going to be, I think, close to that range, again the 50% to 53% range is a good number to look at for the year -- for the rest of the year.

And we'll take our next question from David Amsellem from Piper Sandler.

So just a couple for me. One on Primatene. Can you just talk about the weakness there, at least on the volume side. And then secondly, on shortages. I know this is something that have a recurring feature where you're benefiting from shortages. It looked like it was maybe, perhaps, larger this quarter than others. So how are you thinking about contribution from products that are benefiting from market shortages like dextrose as the year progresses? And can you quantify that? And then sorry if I missed this but on glucagon. Can you say what the mix is between institutional and noninstitutional is? I know that the institutional setting as a diagnostic was something that you were prioritizing in the context of expanded capacity. So just talk about where you're getting your orders from regarding glucagon?

I'll take the first one on the Primatene. And what I had mentioned was that while our sales -- our unit sales were down in the quarter, we saw the in-store data from the retailers actually was up 5%. So I think it's primarily a timing issue of just when orders went out and maybe they bought a little bit more in the fourth quarter than they normally would have or just lowered their inventory levels during the quarter. But what we keep an eye on is really that in-store volume to make sure that that's trending upwards, and it did continue to trend upwards even with the price increase that we instituted during the year. Maybe it's possible that some of the retailers bought a little bit more in December knowing that we were increasing the price in January. On the shortages side, yes, I think there might be some -- we did spike up a little bit in epi and lidocaine. And there's definitely a possibility that some of those numbers come down in the second half of the year, but probably they'll keep that level for at least some time. I also see -- we're still seeing strong demand for the dextrose as well so. And as we've always said here, we increased our capacity a few years back to be able to take advantage of these shortages in demand. And we have the ability to move production to different products, depending on where that demand is coming from at any time. And like I said, this quarter, it was epinephrine, lidocaine and dextrose. We're not sure where it will be next quarter, but it's almost certainly coming from somewhere. And glucagon, I don't have the data here on the institutional versus noninstitutional. But shoot me an e-mail, I'll see if I could follow up with Jacob on that.

[Operator Instructions] And there appear to be no further questions at this time. I'd like to turn the floor back over to management for closing remarks.

Yes. I want to thank everyone for joining us today. We look forward to updating you on our next call, and we remain excited about this year's upcoming opportunities. So thank you again, and have a great day.

Thank you. Ladies and gentlemen, this does conclude today's teleconference. We thank you for your participation. You may disconnect your lines at this time, and have a great day. Thank you.

Thank you.
