Reports Net Revenues of $123.5 Million for the Three Months Ended June 30, 2022

RANCHO CUCAMONGA, CA / ACCESSWIRE / August 8, 2022 / Amphastar Pharmaceuticals, Inc. (NASDAQ:AMPH) ('Amphastar' or the 'Company') today reported results for the three months ended June 30, 2022.

Second Quarter Highlights

• Net revenues of $123.5 million for the second quarter
• GAAP net income of $17.3 million, or $0.33 per share, for the second quarter
• Adjusted non-GAAP net income of $20.7 million, or $0.39 per share, for the second quarter

Dr. Jack Zhang, Amphastar's President and Chief Executive Officer, commented: 'We've maintained momentum through the first half of 2022. Sales remained strong through the second quarter, allowing us to increase our investment in research and development. We are optimistic that sales will continue their upward trajectory into the third quarter, particularly with ganirelix's full quarter of sales and the upcoming launch of vasopressin this month, each of which presents new opportunities for further diversification of our revenue streams.'

* Adjusted non-GAAP net income attributable to Amphastar and Adjusted non-GAAP diluted EPS attributable to Amphastar stockholders 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.

Second Quarter Results

Changes in net revenues were primarily driven by:

• Primatene Mist^® sales increased due to an increase in unit volumes as a result of the continued success of our advertising campaign
• Epinephrine sales increased due to an increase in unit volumes as a result of competitor shortages
• Lidocaine sales increased as a result of an increase in unit volumes
• Phytonadione sales increased due to an increase in unit volumes and higher average selling price
• Other finished pharmaceutical product sales increased due to higher demand for certain products such as dextrose and sodium bicarbonate, largely resulting from competitor shortages, as well as the launch of ganirelix prefilled syringe in late June 2022
• API sales decreased due to the timing of orders from MannKind Corporation

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 Primatene Mist^®
• Decreased in heparin and enoxaparin component purchase commitments since these components are reserved to the lower of cost or net realizable value at the time of commitment
• These factors were partially offset by an overall increases in labor costs, as well as increased costs for heparin, the starting material for enoxaparin, and a lower average selling price for enoxaparin

• Selling, distribution, and marketing expenses increased primarily due to increased advertising and freight expenses
• General and administrative expenses decreased primarily due to a decrease in legal expenses and a decrease in expenses in China due to the restructuring of our subsidiary, Amphastar Nanjing Pharmaceuticals, Co., Ltd. ('ANP'), in 2021
• Research and development expenses increased due to:
  • An increase in expenditure for materials and components, primarily for our AMP-018 and insulin products
  • This increase was partially offset by a decrease in clinical trial expense as a result of a shift in timing for some of our clinical trial studies, as well as a decrease in expenses in China due to the restructuring of ANP in 2021
• The change in non-operating income (expense) net is primarily a result of:
  • Foreign currency fluctuations in 2022
  • A final settlement with Aventis in June 2021 which resulted in the reduction of accrued expense by $2.7 million

Cash flow provided by operating activities for the six months ended June 30, 2022 was $53.6 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) attributed to Amphastar and (ii) Adjusted non-GAAP diluted EPS attributed to Amphastar's stockholders, 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.

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, backlog, sales and marketing of our products, market size and growth, product development, the timing of FDA filings or approvals, including the DMFs of ANP, the timing of product launches, acquisitions and other matters related to our pipeline of product candidates, the timing and results of clinical trials, our share buyback program, and other future events, such as the impact of the COVID-19 pandemic including its variants, the Russia-Ukraine conflict and resulting macroeconomic conditions, such as inflation and rising interest rates, and related responses of business and governments to the pandemic on our operations and personnel, and on commercial activity and demand across our business operations and results of operations. 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, including in our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on March 11, 2022 and in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2022, filed with the SEC on May 10, 2022. In particular, the extent of COVID-19's impact on our business will depend on several factors, including the severity, duration and extent of the pandemic including its variants, as well as actions taken by governments, businesses, and consumers in response to the pandemic, all of which continue to evolve and remain uncertain at this time.
