RANCHO CUCAMONGA, CA / ACCESS Newswire / May 7, 2025 / Amphastar Pharmaceuticals, Inc. (NASDAQ:AMPH) ("Amphastar" or the "Company") today reported results for the three months ended March 31, 2025.

• Adjusted non-GAAP net income of $36.9 million, or $0.74 per share, for the first quarter

Dr. Jack Zhang, Amphastar's President and Chief Executive Officer, commented: "We are confident in the potential of our portfolio, particularly with the growth of BAQSIMI^® and Primatene MIST^®, and the promising pipeline of biosimilars and proprietary products.

First Quarter Results

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

• BAQSIMI^® sales increased primarily due to an increase in unit volume, as we assumed full distribution responsibilities globally at the beginning of 2025

• Primatene MIST^® sales increased primarily due to an increase in unit volumes

• Glucagon sales decreased primarily due to a decrease in unit volumes, as a result of competition

• Epinephrine sales decreased due to both a decrease in unit volumes, as well as a lower average selling price for our multi-dose vial product, as a result of increased competition

• Other pharmaceutical product sales changes were primarily due to:

  • Decrease in sales of enoxaparin, dextrose and naloxone, due to increased competition

  • This decrease was partially offset by an increase in unit volumes of albuterol, which we launched in August 2024, and higher unit sales of phytonadione

• Other revenues decreased as we completed the assumption of distribution responsibilities globally for BAQSIMI^® by the beginning of 2025, with all of BAQSIMI^® related revenues in the current period being recognized in Product revenues, net. Other revenues in the previous period consisted of $14.2 million in BAQSIMI^® sales made by Lilly on our behalf under the Transition Service Agreement, or TSA. The other revenues balance was net of $10.4 million in cost of sales and other expenses

Changes in the cost of revenues and the resulting gross margins were primarily driven by:

• Decrease in other revenues are related to Lilly's sales of BAQSIMI^® under the TSA, which were recorded net of cost of sales and other expenses; as we assumed distribution of BAQSIMI^® to all of our customers by the beginning of 2025, we recorded those sales in product revenues and cost of sales separately

• Lower average selling price for epinephrine multi-dose vials, which is a higher-margin product

• Increase in labor costs

• This was partially offset by an increase in sales of Primatene MIST^® and phytonadione, which are higher-margin products

• Selling, distribution, and marketing expenses increased primarily due to expenses related to the expansion of our sales and marketing efforts related to BAQSIMI^®, including expenses related to our co-promotion contract with MannKind, and sales efforts related to Primatene MIST^®

• Research and development expenses increased primarily due to an increase in salary and personnel-related expenses, as well as an increase in clinical trial expenses, and an increase in U.S. Food and Drug Administration (the "FDA") filing fees.

The change in non-operating income (expenses), net is primarily a result of:

• A decrease in interest income resulting from a decrease in cash and investments

• A decrease in interest expense as a result of the repayment of the mortgage loan with East West Bank, as well as the accretion of the interest on the deferred payment for BAQSIMI^®, both of which were paid in full in June 2024

• A change to other income (expenses), net primarily as a result of foreign currency fluctuation, as well as mark-to-market adjustments relating to our interest rate swap contracts during the three months ended March 31, 2025

Cash flow provided by operating activities for the three months ended March 31, 2025, was $35.1 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, expenses related to our acquisition of BAQSIMI^®, 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.
