Dan Dischner: Thank you, Paul. Good afternoon, everyone, and thank you for joining Amphastar’s First Quarter 2026 Earnings Call. Before we begin, I’d like to recognize the continued dedication of our employees across Amphastar. Their commitment to ensuring reliable access to essential medicines remains central to who we are and how we operate. Our first quarter performance demonstrated the continued strength and balance of our underlying business amid a rapidly evolving market landscape with solid commercial execution across our branded and differentiated portfolio alongside meaningful progress in our pipeline. We are actively managing near-term pricing and competitive pressures across certain legacy products with discipline and focus and remain confident that the strategic investments we are making today in our branded portfolio, biosimilars, complex generic pipeline and manufacturing infrastructure are building the foundation for durable long-term growth.

We reported net revenues of approximately $171.2 million for the first quarter, reflecting a return to growth, driven primarily by contributions from recent product launches, while overall performance across the base business remained stable. We saw continued strength in key areas. partially offset by pricing pressure, product mix shifts and increased competition, trends that are broadly consistent with the current market environment. We continue to deploy capital towards initiatives that we believe will drive long-term growth. And while the full benefits of these investments are not yet visible in our financials, we remain confident in the value they will create. From a strategic perspective, our focus remains centered on 3 key priorities: one, strengthening the resilience of our business; two, expanding and optimizing our branded and differentiated portfolio; and three, advancing our pipeline of complex and proprietary products.

First, strengthening the resilience of our core business. We continue to see variability in pricing and competitive intensity across certain legacy products. We remain disciplined in managing costs and focusing on operational efficiency, ensuring supply reliability and maintaining our position in essential product categories. This stability provides the foundation that supports both our near-term performance and our ability to invest in future growth. Second, expanding and optimizing our branded and differentiated portfolio. Products such as BAQSIMI and Primatene MIST remains center to our long-term growth strategy and continue to demonstrate underlying demand in the first quarter. BAQSIMI generated approximately $32 million in revenue this quarter.

While reported revenue was impacted by higher rebates, channel mix and increased utilization of government programs, these dynamics did not reflect the underlying demand. It is also important to note that rebate pressure across these channels is an industry-wide dynamic and not unique to our portfolio. Demand trends remain positive with U.S. sales unit volumes increasing approximately 8% year-over-year. We are actively addressing these factors through investments in rebate management, contracting strategy and program optimization. We expect these pressures to moderate over time and remain confident in BAQSIMI’s long-term growth trajectory. Primatene MIST generated approximately $30 million in revenue in the quarter, with performance driven by sustained consumer demand, continued commercial investment and brand strength.

The brand maintained strong momentum with store level sales increasing approximately 6.5% year-over-year, reflecting incremental consumer adoption and an ongoing impact of our marketing program. In addition, we recently received FDA approval for AMP-007, our Ipratropium Bromide inhalation product and successfully launched the product in April. The launch is progressing as planned and reinforces our ability to execute across development, regulatory approval, manufacturing and commercialization in technically complex product categories. Importantly, our product is currently the first and only generic Ipratropium inhaled inhalation product on the market. Which we believe positions us for a meaningful near-term commercial opportunity. Third, advancing our pipeline of complex and proprietary products.

We are continuing to expand our efforts towards higher-value opportunities, including proprietary and biosimilar programs, which now represent a significant and growing portion of our pipeline. Our strategy is built on a foundation that we have developed over many years, combining regulatory expertise, vertically integrated manufacturing and commercial capabilities to efficiently advance complex products from development through commercialization. This integrated platform allows us to move efficiently while maintaining control over quality, time lines and cost. We continue to make steady progress across key programs, including our insulin aspart biosimilar and our GLP-1 ANDA program, both of which remain on track for planned commercial launches in 2027.

At the same time, we continue to develop our next-generation proprietary assets, including programs in oncology and immunology. While these programs remain in early stages, we are encouraged by the progress to date and are focused on advancing them through IND submissions and into clinical development. Together, these efforts reflect our broader objective of expanding into higher-value therapeutic areas over time. Our continued investment in these programs is underpinned by a strong financial position. The cash flow generated by our commercial portfolio supports ongoing internal R&D while allowing flexibility in how we allocate capital. This enables us to advance our proprietary programs in a disciplined manner without relying on external financing or partnerships.

We also continue to actively evaluate targeted acquisitions and licensing opportunities that align with our existing capabilities, and our balance sheet provides the capacity to pursue these in a disciplined and selective manner. Looking ahead, we expect the operating environment to remain dynamic, particularly regarding pricing and competitive pressures. Against this backdrop, we are focused on disciplined execution while continuing to invest in the capabilities that underpin our long-term strategy. We believe this balanced approach grounded in diversification, operational rigor and sustained investment in our proprietary pipeline positions us to navigate near-term variability and support durable long-term growth. Over the next 12 to 18 months, we expect continued contribution from our commercial portfolio, supported by BAQSIMI, Primatene MIST and the recent launch of our ipratropium bromide.

In parallel, we are focused on executing the next phase of our pipeline strategy with several important regulatory and development milestones ahead. This includes progress across our biosimilar programs as well as our continued advancement of our emerging proprietary assets, which we believe are centered to the long-term growth profile. We have updated the corporate presentation on our website with time lines for our proprietary candidates. I will now turn the call over to Bill Peters, our CFO and Executive Vice President of Finance, for a more detailed financial review of the first quarter.

William Peters: Thank you, Dan, and good afternoon, everyone. In my comments today, I will discuss the first quarter results and then update some of our assumptions for 2026. Revenues for the first quarter increased to $171.2 million from $170.5 million in the previous year’s period. BAQSIMI’s revenues decreased 15% to $32.4 million compared to $38.4 million in the prior year period as a result of lower average selling prices, which were partially offset by an 8% increase in units sold. The lower average selling price of BAQSIMI was driven by higher rebates and higher 340B pharmacy discounts, some of which may have been duplicated. Primatene MIST sales grew to $29.8 million in the first quarter, up 2% from $29.1 million in the first quarter of last year.

Epinephrine sales increased 3% to $19.2 million from $18.6 million as increased demand for our prefilled syringe product was partially offset by increased competition for our multi-dose vial products. Glucagon injection sales declined 56% to $9.2 million from $20.8 million due to increased competition and a shift to ready-to-use products. Other finished pharmaceutical product sales increased 34% to $67.1 million from $50 million, primarily due to recently launched products, including an increase in albuterol sales of $2.8 million, iron sucrose sales of $1.4 million and teriparatide sales of $2.2 million, which we launched in August 2024, August 2025 and December 2025, respectively. Dextrose sales also increased due to shortages from other suppliers, while phytonadione sales declined due to increased competition.

Cost of revenues increased to $100.8 million from $85.3 million. Gross margins declined to 71% of revenues in the first quarter of 2026 from 50% in the previous year. The primary drivers of the change were a lower average selling price for BAQSIMI as well as lower sales of glucagon, phytonadione and epinephrine multi-dose vials, which are higher-margin products. Additionally, increased costs at our Amphastar facility negatively impacted margins. Selling, distribution and marketing expenses were relatively unchanged at $11.9 million. General and administrative spending increased 13% to $18 million from $16 million, driven by higher legal expenses, salary and personnel-related expenses and expenses related to the implementation of our new ERP system.

Research and development expenditures increased 33% to $26.7 million from $20.1 million due to the $2 million upfront payment made to in-license a new corticotropin product and spending on our insulin, inhalation and proprietary product pipeline. Our nonoperating expense of $3.6 million compares to a nonoperating expense last year of $6.4 million, primarily due to foreign currency fluctuations as well as mark-to-market adjustments related to our interest rate swap contracts in the quarter. Net income decreased to $6.4 million or $0.14 per share in the first quarter from $25.3 million or $0.51 per share in the first quarter of 2025. Adjusted net income decreased to $19.5 million or $0.42 per share compared to an adjusted net income of $36.9 million or $0.74 per share in the first quarter of last year.

Adjusted earnings exclude amortization, equity compensation and onetime events. In the first quarter, we had cash flow from operations of approximately $47.8 million. During the quarter, we accelerated our share repurchase program and bought back $29.5 million worth of shares, which represents about 3% of our share count. Before I turn the call back over to Dan, I would like to update some of our guidance for 2026. We now believe that BAQSIMI revenue growth will be flat to up low single-digit percentages compared to last year due to the previously mentioned pricing pressures. In response to these pricing dynamics, we have taken additional steps to strengthen the durability of this business, including engaging a third party to support data-driven identification, validation and resolution of potential 340B duplicate discount.

Additionally, we have implemented a 3% list price increase on BAQSIMI as of May 1. Importantly, even with this revised outlook for BAQSIMI, we are maintaining our overall corporate sales guidance of mid-single-digit to high single-digit unit growth. This reflects the strength of our broad portfolio, including ipratropium bromide inhalation, which we launched in April and currently does not face any generic competitors. I’ll now turn the call back over to Dan.

Dan Dischner: Thanks, Bill. In summary, our first quarter performance reflects our resilience and ability to execute in a dynamic market and environment. Growth was supported by new product launches and stable performance across our base portfolio while actively managing pricing and competitive pressures. BAQSIMI and Primatene MIST continue to demonstrate solid underlying demand, and we are taking targeted actions to improve net pricing and optimize performance over time. The recent approval and launch of our ipratropium bromide inhalation product adds an important near-term growth driver. We remain on track with late-stage programs, including our insulin aspart biosimilar and our GLP-1 ANDA, both expected in 2027, while continuing to advance our early-stage proprietary pipeline.

With a strong financial position, we are focused on executing against our strategy, navigating near-term variability and positioning the business for sustained long-term growth. With that, we will now take your questions. Operator?

Operator: [Operator Instructions] Our first question is from Serge Belanger with Needham & Company.

Serge Belanger: A couple of questions on BAQSIMI. So obviously, there were some headwinds in the first quarter. Just curious how much of it was seasonality peculiar to the first quarter? How much of it will continue to linger into the continuing quarters here? Specifically on price, can you talk about the price decrease and where you think you can get it to with the activities you’ll be undertaking? And last one on BAQSIMI. In the past, you had talked about discontinuing commercialization in some international markets. Has that started to occur? And what impact would that have on the top — on sales levels?

William Peters: Yes. So the pricing issue that we’ve been encountering appears to be potentially the increase of — there’s multiple things going on there. One, there’s some increased rebates, but also potentially, we believe some duplicate rebates, which seems to be a 340B pharmacy issue. So what we’ve undertaken is to engage an outside consultant or outside firm to basically validate these claims before they’re paid. So we believe that in doing that, we will stop that practice. We just engaged that firm and that process began at the beginning of May. So that trend continues into April, but we hope that changes in May. Additionally, the 3% price increase that we took is also effective May 1. So we believe that we could get at least part way back to the pricing where we were last year or most of the way back later this year, but part of the way back this quarter.

And seasonality did not have anything to do with that. And as far as the discontinuation from certain international markets, we’ve talked about withdrawing from a handful of markets. The — that situation is that we have given notice in some countries that require a lengthy notice period. And also, we have some inventory in other countries that we plan to discontinue. So the discontinuation would begin in July, but it’s not going to be all at once because some — like I said, so some countries are going to have inventory that might extend into August or September and others with a notice period requirement will keep selling probably through the end of this year and into the first quarter of next year. So it’s not going to be a falloff. And remember, we’ve also characterized this as 80% of our sales were in the United States last year, only 20% were foreign, and we’re only going to drop out of a handful of countries out of the 20-something foreign countries.

So we’re going to remain in most of the foreign countries, including all of the top-selling markets. So it’s not going to be a significant decrease in the third quarter. And also the other way to think about it is that last year, U.S. sales were 80%. This year, they’re probably going to be closer to 85%.

Operator: Our next question is from Dennis Ding with Jefferies.

Anthea Li: This is Anthea on for Dennis. We just had 2 on the pipeline. First, on the synthetic corticotropin, I see in your slides that you’re thinking to go into Phase I in 2027. I’m curious if you’ve met with the FDA and had regulatory alignment there and whether there could be an accelerated path? And then second, any updates on 004, the insulin aspart? I think the prior PDUFA was planned for 2026. So just curious on any additional color there.

Dan Dischner: Okay. I’ll take the first one, the update on 004. It’s — we’re just — it’s still in progress and nothing has changed. We still plan on commercializing it in 2027. On your other question regarding — yes, Tony, if you can take that one?

Tony Marrs: Sure. Sure. For 110, we have not met with the agency for that. We think the possibility is there for — among these pipeline products for expedited approvals, but we haven’t met with the agency, and we don’t have alignment with them on that.

Operator: Our next question is from Ekaterina Knyazkova with JPMorgan.

Ekaterina Knyazkova: Actually, another one on AMP-004. Just can you remind us how you’re thinking about the size of that opportunity and just how quickly it could ramp in ’27? And then second question is just on glucagon. Is the Q1 number a good kind of tailwind for the product? Or would you expect sequential erosion from that Q1 number?

William Peters: Yes. So for the first one, this is a product that still has over $1 billion in sales. So we think that it’s going to be a relatively large product for us and a meaningful product for us when we launch that. We do think it will take a little time to get sales and also will depend on whether we have the interchangeability or not, which we would like to get right away. So there’s going to be a couple of different drivers, and we should have a little more idea of that timing and pathway next year. And as far as glucagon, I will say that, no, we have not reached the bottom of that yet, but I’ll say the rate of decline is slowing significantly. So it will decline from here, but not at the same rate that it’s been declining.

Operator: Our next question is from David Amsellem with Piper Sandler.

Naoki Martin: This is Naoki on for David. So first on Primatene MIST, how should we think about generic competition? And do you have any updates regarding life cycle management? So that’s number one. Number two, how should we think about revenue contribution from 007 and the extent of the opportunity here?

Dan Dischner: Well, Primatene MIST, we have not been notified or have no visibility on whether or not there is a generic in place. We’ve always taken the position that we believe it would be very difficult to genericize this product. Primatene MIST has 60 years of brand recognition. The product would be — it’s over the counter. It would be difficult regulatory-wise. It’s not a similar — it’s not — because it’s retail and it’s over-the-counter, it has — it’s different market dynamics than what you would see with a typical generic. So we haven’t really — we have no visibility outside of that. As far as our next generation, we have — as we said, we have in our pipeline, we have a green version that we’re working on. We have one patent already and another one pending, and we continue to advance that through development.

William Peters: Yes, on 007, we haven’t given anybody — we haven’t given a sales forecast on that. However, we have said that, that would be our biggest growth driver this year, and we had a couple of different scenarios. And we said that even when we thought that there might be a generic competitor on the market with us. As of today, there isn’t, and we launched this in mid-April. So right now, we’re almost a month into it without a generic competitor. So that’s one of the reasons why we’re able to maintain our high — our mid-single-digit to high single-digit sales growth guidance for the year that I believe that this product will outpace our original assumptions.

Operator: There are no further questions at this time. I would like to hand the floor back over to management for any closing remarks.

Dan Dischner: Thank you, Paul. Thank you all for your questions and your continued interest in Amphastar. We remain focused on executing against our strategy and advancing the initiatives we discussed today. We appreciate your continued support and look forward to updating you on our progress next quarter. Have a great day.

Operator: This concludes today’s conference. You may disconnect your lines at this time. Thank you for your participation.
