Following European approval of Roche's Tecentriq SC, we look forward to potential U.S. approval for Tecentriq SC in September 2024. Roche has also received a recommendation for approval of ocrelizumab SC by the European Medicines Agency's Committee for Medicinal Products for Human Use, with final approval expected mid-year and a potential U.S. approval in September 2024. Continuing our strong Wave 3 progress, BMS recently announced a U.S. Prescription Drug User Fee Act goal date of February 28, 2025 for nivolumab SC," said Dr. Helen Torley, president and chief executive officer of Halozyme.

First Quarter 2024 Financial Highlights:

• Revenue was $195.9 million compared to $162.1 million in the first quarter of 2023. The 21% year-over-year increase was primarily driven by royalty revenue growth and an increase in milestone revenue. Revenue for the quarter included $120.6 million in royalties, an increase of 21% compared to $99.6 million in the prior year period, primarily attributable to increases in revenue of subcutaneous DARZALEX® (daratumumab) and Phesgo®.
• Cost of sales was $28.3 million, compared to $35.2 million in the first quarter of 2023. The decrease was primarily driven by lower bulk rHuPH20 sales, partially offset by higher proprietary product sales.
• Amortization of intangibles expense remained flat at $17.8 million compared to the first quarter of 2023.
• Research and development expense was $19.1 million, compared to $18.0 million in the first quarter of 2023. The increase was primarily due to planned investments in ENHANZE®.
• Selling, general and administrative expense was $35.1 million, compared to $37.4 million in the first quarter of 2023. The decrease was primarily due to reductions in commercial marketing expense, partially offset by increased compensation expense.
• Operating income was $95.5 million, compared to $53.8 million in the first quarter of 2023.
• Net Income was $76.8 million, compared to $39.6 million in the first quarter of 2023.
• EBITDA and Adjusted EBITDA were $115.7 million, compared to $74.3 million in the first quarter of 2023.1
• GAAP diluted earnings per share was $0.60, compared to $0.29 in the first quarter of 2023. Non-GAAP diluted earnings per share was $0.79, compared to $0.47 in the first quarter of 2023.1
• Cash, cash equivalents and marketable securities were $463.5 million on March 31, 2024, compared to $336.0 million on December 31, 2023. The increase was primarily a result of cash generated from operations.

Note Regarding Use of Non-GAAP Financial Measures

In addition to disclosing financial measures prepared in accordance with U.S. generally accepted accounting principles ("GAAP"), this press release and the accompanying tables contain certain non-GAAP financial measures. The Company reports earnings before interest, taxes, depreciation, and amortization ("EBITDA"), adjusted EBITDA and Non-GAAP diluted earnings per share, and guidance with respect to those measures, in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The Company calculates non-GAAP diluted earnings per share excluding share-based compensation expense, amortization of debt discounts, intangible asset amortization, inventory adjustments and certain adjustments to income tax expense. The Company calculates EBITDA excluding interest, taxes, depreciation and amortization. The Company calculates adjusted EBITDA excluding one-time items. Reconciliations between GAAP and Non-GAAP financial measures are included at the end of this press release. The Company does not provide reconciliations of forward-looking adjusted measures to GAAP due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation, including adjustments that could be made for changes in share-based compensation expense and the effects of any discrete income tax items. The Company evaluates other items of income and expense on an individual basis for potential inclusion in the calculation of Non-GAAP financial measures and considers both the quantitative and qualitative aspects of the item, including (i) its size and nature, (ii) whether or not it relates to the Company's ongoing business operations and (iii) whether or not the Company expects it to occur as part of the Company's normal business on a regular basis. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titled measures presented by other companies. These non-GAAP financial measures are not meant to be considered in isolation and should be read in conjunction with the Company's consolidated financial statements prepared in accordance with GAAP; and are not prepared under any comprehensive set of accounting rules or principles. In addition, from time to time in the future there may be other items that the Company may exclude for purposes of its non-GAAP financial measures; and the Company may in the future cease to exclude items that it has historically excluded for purposes of its non-GAAP financial measures. The Company considers these non-GAAP financial measures to be important because they provide useful measures of the operating performance of the Company, exclusive of factors that do not directly affect what the Company considers to be its core operating performance, as well as unusual events. The non-GAAP measures also allow investors and analysts to make additional comparisons of the operating activities of the Company's core business over time and with respect to other companies, as well as assessing trends and future expectations. The Company uses non-GAAP financial information in assessing what it believes is a meaningful and comparable set of financial performance measures to evaluate operating trends, as well as in establishing portions of our performance-based incentive compensation programs.

Safe Harbor Statement

In addition to historical information, the statements set forth in this press release include forward-looking statements including, without limitation, statements concerning the Company's financial performance (including the Company's financial outlook for 2024) and expectations for future growth, profitability, total revenue, royalty revenue, revenue durability, EBITDA, Adjusted EBITDA, non-GAAP diluted earnings-per-share and potential share repurchase under its share repurchase program. Forward-looking statements regarding the Company's ENHANZE® drug delivery technology may include the possible benefits and attributes of ENHANZE®, its potential application to aid in the dispersion and absorption of other injected therapeutic drugs and facilitating more rapid delivery and administration of higher volumes of injectable medications through subcutaneous delivery. Forward-looking statements regarding the Company's business may include potential growth and receipt of royalty and milestone payments driven by our partners' development and commercialization efforts, potential new clinical trial study starts and clinical data, regulatory submissions and product launches, the size and growth prospects of our partners' drug franchises, potential new or expanded collaborations and collaborative targets and regulatory review, PDUFA action dates and potential approvals of new partnered or proprietary products. These forward-looking statements are typically, but not always, identified through use of the words "expect," "believe," "enable," "may," "will," "could," "intends," "estimate," "anticipate," "plan," "predict," "probable," "potential," "possible," "should," "continue," and other words of similar meaning and involve risk and uncertainties that could cause actual results to differ materially from those in the forward-looking statements. Actual results could differ materially from the expectations contained in these forward-looking statements as a result of several factors, including unexpected levels of revenues, expenditures and costs, unexpected delays in the execution of the Company's share repurchase program, unexpected results or delays in the growth of the Company's business, or in the development, regulatory review or commercialization of the Company's partnered or proprietary products, regulatory approval requirements, unexpected adverse events or patient outcomes and competitive conditions. These and other factors that may result in differences are discussed in greater detail in the Company's most recent Annual Report on Form 10-K and Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission. Except as required by law, the Company undertakes no duty to update forward-looking statements to reflect events after the date of this release.
