BRIDGEWATER, NJ, March 1, 2024 - Amneal Pharmaceuticals, Inc. (Nasdaq AMRX) ("Amneal" or the "Company") today announced its results for the fourth quarter and full year ended December 31, 2023.

"Amneal had a very successful year in 2023 as we delivered strong execution and growth across our diversified pharmaceutical business. We are starting 2024 with substantial momentum and key catalysts, including complex high-value products, biosimilars and specialty, to further expand our reach. Against the macro backdrop of a global aging population, significant unmet patient needs and ongoing supply issues, Amneal's mission to provide access to high-quality, affordable, essential medicines has never been more important or more aligned with industry dynamics. Our durable business is ideally positioned to drive sustainable, profitable growth and create value for all our stakeholders, this year and beyond," said Chirag and Chintu Patel, Co-Chief Executive Officers.

Net revenue in the fourth quarter of 2023 was $617 million, an increase of 1% compared to $610 million in the fourth quarter of 2022. The increase was driven by AvKARE revenues growing 38% due to new launches and Specialty revenues growing 2% driven by key branded products, partially offset by Generics revenues declining 9% as strong performance of biosimilars and complex generics was offset by the timing of orders. Net loss attributable to Amneal Pharmaceuticals, Inc. was $99 million in the fourth quarter of 2023 compared to a net loss of $4 million in the fourth quarter of 2022, primarily due to non-cash intangible asset impairment charges and costs associated with our term loan refinancing. Adjusted EBITDA(1) in the fourth quarter of 2023 was $142 million, a decrease of 8% compared to the fourth quarter of 2022, primarily due to investments in research and development and commercial to drive future growth. Diluted loss per share in the fourth quarter of 2023 was $0.40, an increase of $0.37 from a loss of $0.03 for the fourth quarter of 2022, due to the aforementioned factors, partially offset by an increase in the weighted-average common shares outstanding as a result of our previously announced reorganization. Adjusted diluted EPS(1) in the fourth quarter of 2023 was $0.14, a decrease of 39% from $0.23 in the fourth quarter of 2022.

Net revenue for the year ended December 31, 2023 was $2.39 billion, an increase of 8% compared to $2.21 billion for the year ended December 31, 2022. Revenue growth was driven by all three business segments with AvKARE growing 31%, Generics growing 3% due to strong performance of our complex portfolio and biosimilars, and Specialty growing 4%. Net loss attributable to Amneal Pharmaceuticals, Inc. was $84 million for the year ended December 31, 2023, an improvement of $41 million compared to a net loss of $130 million for the year ended December 31, 2022. Adjusted EBITDA(1) for the year ended December 31, 2023 was $558 million, an increase of $44 million compared to the year ended December 31, 2022, reflective of strong revenue growth and continued operating expense leverage. Diluted loss per share for the year ended December 31, 2023 was $0.48, a decrease of 44% compared to diluted loss per share of $0.86 for the year ended December 31, 2022. Adjusted diluted EPS(1) in the year ended December 31, 2023 was $0.64, a decrease of 6% from $0.68 for the year ended December 31, 2022, due to higher EBITDA offset by higher interest expense.

Non-GAAP Financial Measures

This release includes certain non-GAAP financial measures, including EBITDA, adjusted EBITDA, adjusted net income and adjusted diluted EPS, which are intended as supplemental measures of the Company's performance that are not required by or presented in accordance with GAAP. Adjusted diluted EPS reflects diluted earnings per share based on adjusted net income, which is net loss adjusted to (A) exclude (i) non-cash interest, (ii) GAAP provision for (benefit from) income taxes, (iii) amortization, (iv) stock-based compensation, (v) acquisition, site closure expenses, and idle facility expenses, (vi) restructuring and other charges, (vii) loss on refinancing, (viii) charges related to certain legal matters, including interest, net, (ix) asset impairment charges, (x) regulatory approval milestone, (xi) change in fair value of contingent consideration, (xii) insurance recoveries for property losses and associated expenses (xiii) increase in tax receivable agreement liability, (xiv) system implementation expense, (xv) reorganization expenses, (xvi) other and (xvii) net income attributable to non-controlling interests not associated with class B common stock, and (B) include non-GAAP provision for income taxes. Non-GAAP adjusted diluted EPS was calculated assuming (i) the weighted average diluted shares outstanding of class A common stock and (ii) as if all shares of class B common stock were converted to shares of class A common stock as of January 1, 2022.

Management uses these non-GAAP measures internally to evaluate and manage the Company's operations and to better understand its business because they facilitate a comparative assessment of the Company's operating performance relative to its performance based on results calculated under GAAP. These non-GAAP measures also isolate the effects of some items that vary from period to period without any correlation to core operating performance and eliminate certain charges that management believes do not reflect the Company's operations and underlying operational performance. The compensation committee of the Company's board of directors also uses certain of these measures to evaluate management's performance and set its compensation. The Company believes that these non-GAAP measures also provide useful information to investors regarding certain financial and business trends relating to the Company's financial condition and operating results facilitates an evaluation of the financial performance of the Company and its operations on a consistent basis. Providing this information therefore allows investors to make independent assessments of the Company's financial performance, results of operations and trends while viewing the information through the eyes of management.

These non-GAAP measures are subject to limitations. The non-GAAP measures presented in this release may not be comparable to similarly titled measures used by other companies because other companies may not calculate one or more in the same manner. Additionally, the non-GAAP performance measures exclude significant expenses and income that are required by GAAP to be recorded in the Company's financial statements do not reflect changes in, or cash requirements for, working capital needs and do not reflect interest expense, or the requirements necessary to service interest or principal payments on debt. Further, our historical adjusted results are not intended to project our adjusted results of operations or financial position for any future period. To

compensate for these limitations, management presents and considers these non-GAAP measures in conjunction with the Company's GAAP results no non-GAAP measure should be considered in isolation from or as alternatives to any measure determined in accordance with GAAP. Readers should review the reconciliations included below, and should not rely on any single financial measure to evaluate the Company's business.

A reconciliation of each historical non-GAAP measure to the most directly comparable GAAP measure is set forth below.
