Rhea-AI Filing Summary

Amphastar Pharmaceuticals reported first quarter 2026 results showing flat revenue but significantly lower profit. Net revenues were $171.2 million, essentially unchanged from $170.5 million a year earlier, while GAAP net income fell to $6.4 million from $25.3 million. GAAP diluted EPS declined to $0.14 from $0.51, and adjusted non-GAAP diluted EPS decreased to $0.42 from $0.74.

Gross profit dropped to $70.3 million from $85.3 million as gross margin narrowed to 41.1% from 50.0%, reflecting an 18% rise in cost of revenues. Research and development spending increased 33% to $26.7 million and general and administrative expense rose 13% to $18.0 million. Despite lower earnings, cash flow provided by operating activities was $47.8 million.

The company highlighted the approval and launch of Ipratropium Bromide HFA, an exclusive license for a fully synthetic corticotropin compound, and progress across a proprietary and biosimilar pipeline. Current filings include one ANDA and one biosimilar insulin candidate targeting markets over $1.6 billion, plus additional biosimilar and generic programs addressing several billion dollars of estimated market opportunity.

Positive

  • None.

Negative

  • Profitability deterioration: GAAP net income dropped to $6.4 million from $25.3 million and gross margin compressed from 50.0% to 41.1%, indicating materially weaker earnings despite flat revenue.

Insights

Q1 2026 shows sharp earnings compression despite flat revenue and solid cash flow.

Amphastar delivered Q1 2026 net revenues of $171.2 million, essentially unchanged year over year, but profitability deteriorated. GAAP net income fell to $6.4 million from $25.3 million, and adjusted non-GAAP net income declined to $19.5 million from $36.9 million.

Gross margin contracted from 50.0% to 41.1% as cost of revenues rose 18%. Operating expenses increased, with research and development up 33% to $26.7 million and general and administrative up 13% to $18.0 million, indicating heavier investment and cost pressure.

Non-operating expenses improved, and operating cash flow remained strong at $47.8 million, supporting the balance sheet. Management emphasized new launches such as Ipratropium Bromide HFA and a broader pipeline, including programs addressing markets exceeding $6.1 billion in aggregate market size, but the near-term impact on margins is not quantified in this excerpt.

"Adjusted non-GAAP net income * | $ | 19,478 | $ | 36,871"
abbreviated new drug application regulatory
"The Company currently has one abbreviated new drug application (“ANDA”) and one biosimilar insulin candidate"
An abbreviated new drug application is a regulatory submission used to gain approval to market a generic version of an already approved prescription medicine by showing it is equivalent in effect and safety to the original product, without repeating full clinical trials. For investors, an approval signals a lower-cost competitor entering the market that can quickly capture sales from the branded drug, similar to a generic knock‑off replacing a name‑brand item on store shelves.

"one abbreviated new drug application (“ANDA”) and one biosimilar insulin candidate filed with the FDA targeting products"
interest rate swap contracts financial
"mark-to-market adjustments relating to our interest rate swap contracts during the three months ended March 31, 2026."
A contract where two parties agree to exchange streams of interest payments so one side takes a fixed rate and the other a variable rate tied to market interest levels; no loan principal changes hands, just the differing payment amounts. Investors care because swaps let companies and funds manage interest-rate risk or speculate on rate moves—like trading a variable mortgage for a fixed one—to stabilize borrowing costs or alter portfolio sensitivity to rising or falling rates.

Changes in net revenues as compared to the first quarter of the prior year were primarily driven by:

BAQSIMI® sales decreased primarily due to a lower average selling price, as a result of a change in gross-to-net discounts due to changes in chargebacks and rebates and changes to the customer mix, impacting sales of approximately $8.0 million. This decrease was partially offset by an increase in unit volumes, contributing $2.0 million in sales driven by our continued marketing efforts
Primatene MIST® sales increased due to an increase in unit volumes
Epinephrine sales increased primarily due to an increase in demand for our epinephrine pre-filled syringe, as a result of other supplier shortages, contributing $4.1 million in sales. This increase was partially offset by a decrease in our epinephrine multi-dose vial product, as a result of increased competition, impacting sales by $3.5 million
Glucagon sales decreased primarily due to a decrease in unit volumes, impacting sales by $6.1 million, as well as a lower average selling price, which impacted sales by $5.6 million, as a result of competition and the continued shift to ready to use glucagon products such as BAQSIMI®
Other pharmaceutical product sales increased 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. An increase in dextrose sales, driven by heightened demand resulting from supplier shortages in the market also positively impacted sales

Pipeline Information

The Company currently has one abbreviated new drug application (“ANDA”) and one biosimilar insulin candidate filed with the FDA targeting products with a combined market size exceeding $1.6 billion, along with two biosimilar products in development targeting products with a market size exceeding $3.7 billion, and two generic products in development targeting products with a market size of over $0.8 billion. This market information is based on IQVIA data for the 12 months ended March 31, 2026. The Company is developing multiple proprietary products with injectable, topical and intranasal dosage forms.

The Company’s proprietary pipeline also includes four recently in-licensed products including three proprietary peptides targeting oncology and ophthalmology indications, and a fully synthetic corticotropin compound designed to address inflammatory and autoimmune conditions.

Conference Call Information

The Company will hold a conference call to discuss its financial results today, May 7, 2026, at 2:00 p.m. Pacific Time.

To access the conference call, dial toll-free (877) 407-0989 or (201) 389-0921 for international callers, ten minutes before the conference.

The call can also be accessed on the Investors page on the Company’s website, www.amphastar.com.

Non-GAAP Financial Measures

To supplement its consolidated financial statements, which are prepared and presented in accordance with U.S. generally accepted accounting principles (“GAAP”), the Company is disclosing non-GAAP financial measures when providing financial results. The Company believes that an evaluation of its ongoing operations (and comparisons of its current operations with historical and future operations) would be difficult if the disclosure of its financial results were limited to financial measures prepared only in accordance with GAAP. As a result, the Company is disclosing certain non-GAAP results, including (i) Adjusted non-GAAP net income (loss) and (ii) Adjusted non-GAAP diluted EPS, which generally excludes amortization expense, share-based compensation, impairment charges, certain debt issuance costs, legal settlements, and other one-time events in order to supplement investors’ and other readers’ understanding and assessment of the Company’s financial performance because the Company’s management uses these measures internally for forecasting, budgeting, and measuring its operating performance. Whenever the Company uses such non-GAAP measures, it will provide a reconciliation of non-GAAP financial measures to their most directly comparable GAAP financial measures. Investors and other readers are encouraged to review the related GAAP financial measures and the reconciliation


of non-GAAP measures to their most directly comparable GAAP measures set forth below and should consider non-GAAP measures only as a supplement to, not as a substitute for or as a superior measure to, measures of financial performance prepared in accordance with GAAP.

Although we believe that our industry sources are reliable, we do not independently verify the information. The market data may include projections that are based on a number of other projections.

Forward Looking Statements

All statements in this press release and in the conference call referenced above that are not historical are forward-looking statements, including, among other things, statements relating to our expectations regarding future financial performance and business trends, our future growth and our ability to continue to scale, sales and marketing of our products, market size and expansion, product portfolio, product development, the timing of FDA filings or approvals, the timing of product launches, acquisitions and other matters related to our pipeline of product candidates, the timing and results of clinical trials, the impact of our products, including their potential for continued revenue growth, the strategic trajectory of and market for our product pipeline, our long-term strategic vision, our ability to leverage our existing expertise and technology, the impacts of any licensing agreements and ability to commercialize additional therapies, our in-house manufacturing expertise, our ability to deliver high-quality, affordable therapies to patients, our commercial momentum and position in the market. These statements are not facts but rather are based on Amphastar’s historical performance and our current expectations, estimates, and projections regarding our business, operations, and other similar or related factors. Words such as “may,” “might,” “will,” “could,” “would,” “should,” “anticipate,” “predict,” “potential,” “continue,” “expect,” “intend,” “plan,” “project,” “believe,” “estimate,” and other similar or related expressions are used to identify these forward-looking statements, although not all forward-looking statements contain these words. You should not place undue reliance on forward-looking statements because they involve known and unknown risks, uncertainties, and assumptions that are difficult or impossible to predict and, in some cases, beyond Amphastar’s control. Actual results may differ materially from those in the forward-looking statements as a result of a number of factors, including those described in Amphastar’s filings with the Securities and Exchange Commission (“SEC”), including in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 26, 2026, and our other filings or reports that we may file with the SEC.
