Reports Net Revenues of $140.0 Million for the Three Months Ended March 31, 2023

RANCHO CUCAMONGA, CA / ACCESSWIRE / May 9, 2023 / Amphastar Pharmaceuticals, Inc. (NASDAQ:AMPH) ("Amphastar" or the "Company") today reported results for the three months ended March 31, 2023.

First Quarter Highlights

• Net revenues of $140.0 million for the first quarter
• GAAP net income of $26.0 million, or $0.50 per share, for the first quarter
• Adjusted non-GAAP net income of $32.1 million, or $0.62 per share, for the first quarter

Dr. Jack Zhang, Amphastar's President and Chief Executive Officer, commented: "Strong sales of glucagon, Primatene MIST^®, and epinephrine played a key role in driving our quarterly sales growth. We expect similar growth trends in our key products to continue while we believe our newly-launched regadenoson and the approval of our intranasal naloxone will add another layer to our complex generics and proprietary products portfolio. Equally important, we expect our proposed BAQSIMI^® acquisition will be the start of a transformative period for the Company - by adding to our diabetes portfolio and by expanding our branded products strategy. We are confident in this market as we believe this product aligns with our key focus areas."

* Adjusted non-GAAP net income and Adjusted non-GAAP diluted EPS are non-GAAP financial measures. Please see the discussion in the section entitled "Non-GAAP Financial Measures" and the reconciliation of GAAP to non-GAAP financial measures in Table III of this press release.

First Quarter Results

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

• Glucagon sales increased by $14.7 million primarily due to an increase in unit volumes
• Primatene MIST^® sales decreased $3.6 million due to reduced unit volumes, which was partially offset by an increase in average selling price contributing $2.4 million
• Epinephrine sales increased by $4.9 million primarily due to an increase in unit volumes caused by shortages at other suppliers
• Lidocaine sales increased primarily due to an increase in unit volumes
• Phytonadione sales decreased due to decreased unit volumes as a new supplier commenced sales
• Naloxone sales decreased primarily due to a lower average selling price
• Other finished pharmaceutical product sales changes were primarily due to:
  • An increase in unit volumes for dextrose, which was in high demand due to shortages at other suppliers
  • Launches of ganirelix and vasopressin, in June 2022 and August 2022, respectively
• Active Pharmaceutical ingredient ("API") sales increased primarily due to the timing of customer purchases

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

• Increased sales of higher-margin products such as glucagon, epinephrine, and lidocaine, as well as the launches of ganirelix and vasopressin in 2022
• These factors were partially offset by overall increases in labor, material and overhead costs

• Selling, distribution, and marketing expenses increased primarily due to increased advertising expense for Primatene MIST^®
• General and administrative expenses increased primarily due to an increase in legal expenses related to the planned purchase of BAQSIMI^®, as well as salary and personnel-related expenses
• Research and development expenses increased due to:
  • An increase in salary and personnel-related expenses
  • Increases in clinical trial expense as we continue to work on external studies related to our insulin and inhalation product pipeline
  • Increases in expenditure for raw materials and components, primarily for our insulin products
• The change in non-operating income, net is primarily a result of:
  • A $5.4 million gain related to a settlement in connection with the regadenoson patent litigation during the three months ended March 31, 2022

Cash flow provided by operating activities for the three months ended March 31, 2023, was $40.4 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 exclude amortization expense, share-based compensation, impairment charges, 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.

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.

In particular, there can be no guarantee that the proposed acquisition of BAQSIMI^® will be completed in the anticipated timeframe or at all, that the conditions required to complete the proposed acquisition of BAQSIMI^® will be met, that the debt commitments will be sufficient to effect the proposed acquisition of BAQSIMI^®, that any event, change or other circumstance that could give rise to the termination of the definitive agreement for the proposed acquisition of BAQSIMI^® will not occur, that all or any of the contingent consideration potentially payable by the Company as a result of the proposed acquisition of BAQSIMI^® will become payable on the terms described therein or at all or that Amphastar can reliably predict the impact of the proposed acquisition of BAQSIMI^® on its financial results or financial guidance.
