RANCHO CUCAMONGA, Calif., Aug. 6, 2026 /PRNewswire/ -- Amphastar Pharmaceuticals, Inc. (NASDAQ: AMPH) ("Amphastar" or the "Company"), a biopharmaceutical company focused on developing, manufacturing, and commercializing technically challenging generic and proprietary injectable, inhalation, and intranasal products, today reported results for the three months ended June 30, 2026.

"Our second quarter results reflect the continued execution of our long-term strategy to build a more diversified and innovative biopharmaceutical company.

These results demonstrate the strength of our integrated business model and position us well for long-term sustainable growth," said Dr. Jack Zhang, Amphastar's President and Chief Executive Officer.

Second Quarter Results

Changes in net revenues as compared to the second 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 $8.1 million. This decrease was partially offset by an increase in unit volumes, contributing $6.9 million in sales driven by our continued marketing efforts.
  • Achieved the first annual net sales milestone under the asset purchase agreement with Eli Lilly & Company, or Lilly, for BAQSIMI^®, with sales of $175.0 million for the contract year. The milestone triggers a payment of $100.0 million to Lilly which is due in the third quarter of 2026.
• Primatene MIST^® sales decreased due to the timing of customer purchases rather than changes in the underlying consumer demand. In store demand shows continued growth.
• Epinephrine sales slightly decreased primarily due to a decrease in our epinephrine multi-dose vial product, as a result of increased competition, impacting sales by $2.2 million. This decrease was partially offset by an increase in demand for our epinephrine pre-filled syringe, as a result of other supplier shortages, contributing $1.9 million in sales.
• Glucagon sales decreased primarily due to a lower average selling price, impacting sales by $7.5 million, as well as a decrease in unit volumes, which impacted sales by $1.2 million, as a result of competition and the continued shift to ready-to-use glucagon products such as BAQSIMI^®.
• Ipratropium bromide sales were $8.4 million following a successful launch in April 2026.
• Other pharmaceutical product sales increased primarily due to recently launched products including an increase in iron sucrose sales of $3.5 million and teriparatide sales of $4.5 million, which we launched in August 2025 and December 2025, respectively. Albuterol sales increased primarily due to an increase in unit volumes, as we continue to see positive growth since its launch in August 2024. Additionally impacting sales, were an increase in phytonadione and sodium bicarbonate sales, driven by heightened demand, and an increase in API sales from our ANP subsidiary.

• Recently launched products, including iron sucrose, teriparatide and ipratropium bromide, as well as an increase in sales of phytonadione, all of which are higher-margin products.
• This was partially offset by:
  • The impact of lower average selling price for BAQSIMI^®, glucagon, and our epinephrine multi-dose vial product
  • Increased manufacturing expenses due to the expansion of our manufacturing facility in Rancho Cucamonga, CA

• Selling, distribution, and marketing expense increased primarily due to increased freight expense and the increase in marketing efforts for BAQSIMI^®.
• General and administrative expenses increased primarily due to an increase in legal expenses, expenses associated with implementing a new ERP system and salary and personnel-related expenses.
• Research and development expenses increased due to an increase in clinical trials expense, primarily for our insulin pipeline products, as well as an increase in salary and personnel-related expenses. This increase was partially offset by a decrease in material and supply expenses.

The change in non-operating expenses, net, is primarily a result of foreign currency fluctuation, as well as the mark-to-market adjustments relating to our interest rate swap contract during the three months ended June 30, 2026.

Cash flow provided by operating activities for the six months ended June 30, 2026, was $99.2 million.

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.
