Thank you, operator. Good afternoon, and thanks for joining Amphastar Pharmaceuticals' fourth quarter earnings call. My name is Dan Dischner, VP of Corporate Communications. Joining me on the call are Bill Peters, CFO; and Tony Marrs, Senior Vice President of Regulatory Affairs and Clinical Operations. We appreciate you joining us today, and we look forward to announcing some very exciting updates. While 2020 was quite an exhilarating year to say the least, and for obvious reasons, on the positive, I'd like to say it was an exceptional year for the company. To start it off, we reported net revenues of $349.8 million for the fiscal year while the fourth quarter saw a net revenue of $95.9 million, making it the best quarter in terms of our sales history. Primatene Mist saw a 3% increase in sales compared to Q3, attributing this mainly to our nationwide TV, radio and digital advertising, along with unit volume increases in our online sales and our recent launch with Kroger. As a result, we are still confident in reaching our $65 million in annualized sales for the product. Furthermore, putting the company on the path towards reaching our sales goals with more ease, we are excited to announce Primatene's launch into Target stores later this month. To add momentum to that launch, we will coincide it with a new television commercial ad campaign. As we have said in the past, we may increase our marketing spend, where we expect our marketing expense to be a lower percentage of sales. However, we're more interested in spending smarter as we plan to expand our reach to the younger 18 to 34-year-old demographic through the use of digital marketing. In other words, as the time-tested and proven marketing saying goes, it's all about reaching the right person with the right message at the right time. And with that kind of thinking, whether it's TV or digital, we'll be poised to structure our marketing expenses at a reasonable enough level while optimizing its influence. Turning to enoxaparin. You'll notice the product saw an increase in sales due to Teva exiting the market. While we've seen the enoxaparin market ebb and flow over the years, and regardless of others entering, leaving or even reentering this market, I'd like to reiterate that our vertically integrated structure — being the only company that manufactures the API and finished product in the United States — continues to make Amphastar a long-term player in this market. In terms of our pipeline, we entered 2021 in a position of strength. Last year, we saw four ANDA approvals in addition to our state-of-the-art high-speed fill line approval. Of the four ANDAs, we saw one grandfathered product approved, atropine. Midyear, we saw succinylcholine chloride while the remaining two were epinephrine multi-dose vial and glucagon, otherwise known as AMP-001. With respect to epinephrine multi-dose vial, you’ll notice some incredible movements as the product signed 86% sales growth compared to Q3. Meanwhile, we continue to see no other generics entering the market. As said in our last call, while we stated we expected to get a fair share of the epinephrine market, we're seeing an upward trend without disrupting the pricing as we've originally planned. However, given the fact that we've recently seen a tremendous upside, we'll continue to look at opportunities to drive our market share while balancing this effort with maintaining optimal pricing. Regarding our newly launched glucagon product, I'd like to say the approval continues to demonstrate the strength and technical and scientific capabilities of Amphastar. This approval was highlighted in the FDA's Office of Generic Drugs 2020 Annual Report, specifically citing it as a significant first-generic approval. Since the launch of this product in February, we're observing some very positive uptake so far in the first quarter and continue to expect to see increases in sales. We're confident in glucagon's launch, relying on our previous experience in the retail markets with products such as enoxaparin and medroxyprogesterone. On the matter of our AMP-002 product in development, we previously disclosed that we received the CRL for the product in late December, and we've already responded to the CRL earlier this year. While CRLs are often common among complex products like AMP-002, we have a GDUFA date in the fourth quarter of this year. Moving forward with previously discussed items, we anticipate our intranasal naloxone to be refiled in the fourth quarter of this year. Regarding our first inhalation ANDA, which I'd like to announce is AMP-008, we've seen very promising results with our PD and PK studies, having been completed with some good guidance and dialogue with the agency. We anticipate AMP-008 to be filed in the first half of this year instead of 2020 because we had some delays due to the COVID pandemic. Additionally, as a gauge of confidence, I can report that we've been building additional capacity at our Massachusetts facility for the inhalation product pipeline. Continuing on the topic of previously discussed items, our insulin programs have seen some exciting development with a path towards interchangeable status. With that said, we're planning to disclose more about this program later this year and just in time to coincide with the 25th anniversary of the company's founding. Turning to our proprietary items. Our intranasal epinephrine has produced clinical study results with a good efficacy and safety profile as reported to the FDA. Thus far, there's been a positive response with the agency where we maintain an open dialogue to move this product forward. As evidenced by our long-term experience with epinephrine, whether in the injectable form or as an inhalation with Primatene, we believe our formulation gives us a competitive advantage with the intranasal presentation as compared against the auto-injector pen form of this product. Concerning AMP-015, a new pipeline item that we announced a few weeks ago, this is another retail product with a greater than $500 million opportunity with no other generics. While we filed AMP-015 as a Paragraph IV with the agency in December of 2020, we anticipate a GDUFA date in the fourth quarter of this year or the first quarter of next year if a pre-approval inspection is needed. Thus far, there has not been a 30-month stay triggered while we continue to believe we do not infringe upon the patent. Finally, I'd like to conclude my portion by emphasizing the journey that Amphastar is on towards transitioning from a generics and specialty-based pharmaceutical company into a proprietary product and biopharmaceutical-based company. While 2020 has been a year where many businesses in our niche have slowed down, it's been an exceptional year for Amphastar. Of course, we owe this thanks to our vertically integrated business model and our original intent which was to place quality as our first priority. This vertically integrated model, coupled with a robust and diverse R&D portfolio — a trait often rare to be seen in a historically generic-focused company — sets Amphastar on a path of resiliency, growth and progression. Amphastar was able to weather the COVID constraints thanks to our vertically integrated structure, and we were also able to navigate through sector-influenced shutdowns such as elective surgeries, thanks to our diversified portfolio, adjusting and offsetting the imbalances seen. Finally, Amphastar has been primarily focused on growing organically. While the company remains diligent in finding opportunities that could enhance our capabilities, we remain focused on our internal development, first and foremost, thus allowing us to transition from a generics and specialty pharma-based company into a biopharma-based company, more focused on proprietary products. I will now turn the call over to our CFO, Bill Peters, to discuss the year-end and fourth quarter financials.

Thank you, Dan. Sales for the fourth quarter of 2020 increased 15% to $95.9 million from $83.4 million in the previous year's period. Importantly, Primatene Mist achieved very strong sales growth of nearly 50% to $13.4 million from $9 million as we continue to see the benefits of our national advertising program. Enoxaparin sales doubled to $17.6 million in the fourth quarter from $8.8 million in the prior year's fourth quarter as we were able to pick up some new business. Additionally, epinephrine sales increased to $7.5 million in 2020 from $4.3 million in the fourth quarter of 2019 due to the launch of epinephrine multi-dose vials. Gross margins declined slightly to 38% of revenues in the fourth quarter of 2020 from 40% of revenues in the fourth quarter of 2019, as significantly higher sales of negative margin enoxaparin offset increases in Primatene Mist and epinephrine multi-dose vials. Selling, distribution and marketing expenses increased slightly to $3.8 million from $3.5 million due to television, radio and digital expenses from marketing Primatene Mist. General and administrative spending increased 15% to $12 million from $10.5 million, primarily due to increased legal expenses, including the cost of settling some employment litigation. Research and development expenditures decreased 8% to $18.1 million from $19.6 million due to decreased clinical trial expenses. Other expenses included a $12.8 million reserve for our litigation with Aventis, which was partially offset by currency gains. The company reported a net loss of $6.3 million or $0.13 per share compared with last year's fourth quarter net loss of $1 million or $0.02 per share. On an adjusted basis, the company reported net income of $8 million or $0.16 per share compared to an adjusted net income of approximately $3.6 million or $0.07 per share in the fourth quarter of last year. Adjusted earnings exclude amortization, equity compensation, impairments of long-lived assets and one-time events. In the fourth quarter, we had cash flow provided by operations of approximately $16.9 million. Also during the fourth quarter, the company repurchased approximately $3.4 million of stock to bring the total repurchases for the year to over $24 million. Now let me review a few of the financial assumptions that we are using as we look to 2021. First, let me state that we expect Primatene Mist to achieve our previously disclosed goal of $65 million in sales this year. We also expect sales growth to be driven by glucagon, which was launched in February, and continued growth in our epinephrine multi-dose vials, which we launched in the second quarter of 2020. Additionally, we could have sales contributions from one or two ANDAs, which have GDUFA dates later this year. When we look to our ANP subsidiary, please remember that, first and foremost, this business is our critical supplier of APIs for current products and, more importantly, our pipeline. That said, we expect continued sales growth to come from ANP, which saw third-party sales double in 2020 to $3.2 million from $1.5 million in 2019. Our expectation is that third-party sales from this facility will more than double again in 2021. We expect gross margins to increase as we sell more Primatene Mist, epinephrine multi-dose vials and most importantly, glucagon, all of which are high-margin products. We also anticipate high margins from sales of any new ANDA approvals that we received this year. Our selling, distribution and marketing expenses will rise as we plan to increase our advertising for Primatene Mist. However, the advertising expense will decrease as a percentage of Primatene Mist sales to provide earnings leverage. This year, we expect G&A spending to increase due to litigation expenses related to Paragraph IV patent challenges. Research and development spending will continue to increase in dollar terms, but we expect it to decline as a percentage of sales as we plan to commence clinical trials for three inhalation products, two insulin products, and continued trials on our intranasal epinephrine. I will now turn the call back over to the operator for Q&A.

Our first question comes from Tim Chiang with Northland Securities.

I had a financial question. It really just ties to gross margins. I mean, what would your gross margins have been if you had excluded enoxaparin? I'm just curious where your steady-state gross margins are. I know you're targeting higher gross margins in 2021. I'm just wondering where you sort of exited if you excluded enoxaparin?

Yes. Well, I haven't done that calculation, but I'll tell you, if you take a look at the enoxaparin sales for the quarter, we had $17.6 million in sales. And basically, what we have to do, we have to reduce the inventory price levels to the point where our assumed future sales are zero. So if you just take out $17.6 million in sales and $17.6 million in cost, you're not going to be too far off. There will be any inventory purchase adjustments if we purchase some new inventory or had commitments for it. So that's what takes it to negative over time. But if you just do that calculation at zero and weight that out then that's a good way to look at it.

Okay. Got it. And then just one follow-up on AMP-002, have you guys responded to the CRL? Or is that response coming in the next two weeks?

Yes. Tim, as Dan had mentioned in part of the script, we have already responded to that CRL.

Okay. And do you get any sort of notification from the FDA once they receive your response? Or is it basically you just wait to get the GDUFA date at some point?

No. They will respond to us with an updated GDUFA date, which they have done, which is the fourth quarter of this year.

Our next question comes from the line of Gary Nachman with BMO Capital.

First, just on 2021 expectations. I appreciate some of the color there. But if you pull it all together, consensus revenue of $428 million implies 22% growth. Consensus EPS of $1.09, 70% growth. Are you comfortable with those levels? And I know you talked about some of the key drivers behind it, but maybe just get us a little bit more comfortable with how you think you could get to those kinds of growth targets for this year if you do feel comfortable with them? And then I have one follow-up.

Yes. So to get to those levels, we would have to have the sales growth. We'd have to get to the Primatene Mist number that we had there. We have to have very strong sales of glucagon, which is a high-margin product. We have to have continued strong sales from the epinephrine vials. We have to more than double our sales at ANP, which I mentioned in there. And in order to get there, we'd really have to have contributions from at least one other ANDA that is not approved at this point. Otherwise, we would not — it would take something that I'm not sure about to get to those levels.

Okay. So you're sort of saying, though, that, that could be a little bit of a stretch. Like everything would have to go perfectly in order to get to those numbers?

I don't want to say everything would have to go perfectly, but I would say that perfectly would be — we'd get the right on time, and we'd be ready to launch and we get the most on the first cycle. So the things that we're looking at getting would be second cycle. So I wouldn't say that we're not assuming any first-cycle approval. So I'd say that we do need contributions from products like AMP-002. And if we got that early enough, then if we did have sales contributions from that being a high-margin product then that could be doable.

Okay. That's helpful. And then just on Primatene, getting to the $65 million this year, I mean, sales have flattened a little bit over the last few quarters. So just talk about how durable are the benefits that you got from COVID? Is there more of a headwind now with more patients going back to see their doctors and getting the prescription products as opposed to retail? It sounds like you'd be more aggressive with DTC this year, just maybe talk about how much more aggressive you're going to be with that? And how much of a benefit do you think you could get from going into Target? And then if there are any other pharmacy chains or retail chains that you guys are looking at this point?

Yes. So we're excited about Target launch. We're in a full chain launch there at the end of this month. And so we're excited about that. We think that's going to help us. We're also expanding into a different demographic as well and really targeting on the digital marketing towards the younger demographic, which we feel like is kind of an untapped market because they weren't really aware of Primatene from the past. And so we really think that the kind of marketing knowledge we have will help us. We're still pretty confident because we believe this product will even grow beyond the $65 million mark. So we're pretty confident right now with that.

Okay. And do you have other retail chains lined up that you think beyond Target?

The reality is we've gotten all the big ones at this point.

And we do have a program where we're launching. We've already, last year, launched into all the wholesalers, and so we have a smaller program targeted at independent chains. But that's — I think there's not really many remaining chains that would have a meaningful boost to sales.

Our next question comes from the line of David Amsellem with Piper Sandler.

Can you provide the underlying brand sales for the inhalation product launched on August 8? Do you anticipate that this will lead to a legal filing? Additionally, regarding the injectable product 015, which you mentioned generates over $500 million, can you confirm that you do not expect any lawsuits related to it? Also, do you foresee any reasonable competition for this asset?

Yes. So first of all, let me start the second question, AMP 015. That is one that is a Paragraph IV challenge. So the time to be sued is up in April. So as of today, we have not been sued, but that time frame is not. And going back to AMP 008, we don't want to disclose what the potential sale or what the IQVIA sales are at this time because given the fact that we have a limited number of these inhalation products, we've disclosed its inhalation, we don't want to kind of tip our hand as to what it is, especially since it's a Paragraph IV challenge.

Our next question comes from the line of Elliot Wilbur with Raymond James.

A couple of follow-up questions on 015. So this is a Paragraph IV filing, you're still within the 45-day statutory window, which the innovator has to commence litigation against you. But I'm curious if you believe that this would be a first to file ANDA? Or are there already pending applications or at least one application?

We're not aware of any other filings at this time.

Okay. And then with respect to glucagon, strong performance-based on the latest weekly data, are you seeing any competitive response here from Lilly? And I know it's a little bit early in the launch, but any anecdotes, given kind of the volume trends and what you're seeing in terms of future orders that you may be drawing away from other glucagon products?

Yes. It's really hard to say where we're drawing from other glucagon products because we're clearly substitutable for Lilly's glucagon. But we don't know if they're going to have any response or not, but I will say that initial sales are strong. So we're happy with the way — at the pace of the rollout at this time.

So our next question comes from David Steinberg with Jefferies.

My first question is just tagging on to Elliot's question. With regard to glucagon, it looks like in the fourth or fifth week of launch at the end of February, the prescriptions really started heating up. Looks like you've captured just about 25% share of the market already. Given that trajectory, would it be reasonable to think that peak sales of this product could be in the range of $40 million to $50 million or so and that you would hit that probably mid-year or so? And then with regards to capital allocation, I know you said, Bill, that you repurchased about $24 million worth of stock for the year. And traditionally, you have made acquisitions, but they've been sporadic, and you've always used cash. Does the pretty significant share repurchase, but a lot of the fact that you just can't find any assets to purchase even though generic drug divestitures or acquisitions of late have been for pretty low multiples. Where are you with business development?

So the first one, the $40 million to $50 million is, we think, a good range to think about as a peak. So I think that's a doable range for us. And as far as the acquisitions go, we've looked at multiple things, but us, the main thing hasn't been the multiple. It's been the right fit and the right acquisition target for us. We've looked at a few things over the last 1.5 years, but not as many over the last 6 months as we did probably in the year before that. But we looked very carefully at a couple of things and ended up not doing those more for strategic fit than anything else because that to us is the most important thing — is where does this fit and where we want to be in the future? And does it help us get there?

Our next question comes from Serge Belanger with Needham & Company.

A couple of questions on Primatene. First, can you just talk about what side of the business that Target distribution represents? Is it something closer to Walmart or Kroger? And then do you expect any seasonality to drive Primatene sales, especially this spring?

So first of all, on the size, Target has significantly fewer locations than Walmart. And so when we looked at where we were with our old formulation of Primatene, Walmart was the biggest customer. Today, really, we kind of see Walmart, CVS and Walgreens as the big three for us in sales, and that's the way it's lining up right now. We expect Target to be an important customer and a large customer, but not to the same level as what we think our biggest three are today. And I'd like to think our fastest-growing segment is on the online, though. So we're making headway online sales.

And on seasonality?

Yes. On seasonality, it's one that — since we've been selling it again, we haven't been able to see a seasonal pattern and we actually just updated our graph and put it up online today around 2:00 o’clock our time. So it just came up right before the call started. If you take a look at that, you can still see that we've got an upward trend. There are some weeks that are higher and some weeks that are lower, but overall, sales are moving in the right direction. It's hard to discern a seasonal trend in that. The only trend that I got was — last year was COVID, and that was a huge spike that kind of obscured everything else. But we're hitting up on the anniversary of that right now. And so maybe at this point, we'll be able to discern better trends this year.

And we've already almost captured that peak. So we're not too far off of that peak from when the pantry loading occurred.

And then in terms of CapEx projects, are there any significant expansions ongoing in any of your U.S. facilities? And is the Chinese facility still undergoing some manufacturing expansions?

Yes. The Chinese facility is still undergoing a significant expansion there with a significant CapEx requirement. But also in the U.S., we have some big projects as well. I think it was alluded to earlier, we're increasing the capacity for our metered dose inhalers out of our Armstrong facility outside of Boston, so that we can ramp up demand for the ANDAs that we have in our pipeline. And we've also added capacity here at Amphastar for our pen syringes. So that's going to be part of — an important part of our insulin program that we're working on. We're also looking forward to the future as we have other approvals coming in the future, we'll add some significant capacity to Amphastar as well to meet that long-term capacity in both vials and prefilled syringes.

I don't want to say it's increasing from 2020, but I'll say that we're maintaining a relatively high level of CapEx spend as we look for future expansion.

And with that, we have reached the end of our question-and-answer session. And I would like to turn the call back over to Mr. Dischner for any closing remarks.

Alright. I want to thank everybody for joining us today and sharing in the exciting advancements that Amphastar saw in 2020 and look forward to 2021. I want to wish everybody to stay safe, and we'll catch you next time.

And this concludes today's teleconference. You may now disconnect your lines at this time. Thank you for your participation, and have a wonderful day.
