Announces New $250 million Accelerated Share Repurchase

Conference Call Scheduled Today at 5:30am PT/8:30am ET

SAN DIEGO, January 8, 2025 -- Halozyme Therapeutics, Inc. (NASDAQ: HALO) ("Halozyme" or the "Company") today provided a financial update, reiterating full year 2024 financial guidance and raising full year 2025 and multi-year financial guidance. The Company also announced it has recently entered into a new $250 million accelerated share repurchase (ASR) program under its previously announced $750 million share repurchase program.

"Halozyme is at the forefront of drug delivery innovation, fostering a high-growth and durable business underpinned by our proprietary ENHANZE drug delivery technology. This leadership position is reflected in the global launch of nine ENHANZE co-formulated products, a robust pipeline and continuing interest from potential new partners," said Dr. Helen Torley, president and chief executive officer. "Our 2025 guidance, with projected revenue growth of 16% to 23% and adjusted EBITDA growth of 24% to 32%, is largely driven by VYVGART Hytrulo, which has received strong early acceptance in generalized myasthenia gravis, and is now seeing growing adoption in CIDP following the June 2024 U.S. approval, and by the continued strong growth of Darzalex SC and Phesgo. Three additional products, Ocrevus Zunovo, Tecentriq Hybreza and Opdivo Qvantig, which are in the early stages of commercialization following recent approvals, are projected to contribute modestly in 2025, growing meaningfully from 2026 onwards. The combined continued projected growth of each product in this exciting de-risked portfolio is what resulted in our also raising our multi-year guidance."

Note Regarding 2024 Preliminary Results

The financial results presented herein are preliminary, estimated, and unaudited. They are subject to the completion and finalization of the Company's financial and accounting close procedures. They reflect management's estimates based solely upon information available to management as of the date of this press release. Further information learned during the completion and finalization of these procedures may alter the final results. These preliminary estimates should not be considered a substitute for the financial information to be filed with the Securities and Exchange Commission on the Company's Form 10-K for the year ended December 31, 2024 once it becomes available. There is a possibility that the Company's financial results for the twelve months ended December 31, 2024 could vary materially from these preliminary estimates. Accordingly, you should not place undue reliance upon this preliminary information.

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, Non-GAAP diluted earnings per share and non-GAAP diluted shares 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, one-time changes, if any, such as changes in contingent liabilities, inventory adjustments, impairment charges, and certain adjustments to income tax expense. The Company calculates non-GAAP diluted shares excluding the dilutive impact of convertible notes which is used in calculating non-GAAP diluted earnings. The Company calculates EBITDA excluding interest, taxes, depreciation and amortization. The Company calculates adjusted EBITDA excluding one-time items, if any such as changes in contingent liabilities, inventory adjustments and impairment charges. 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. For the same reasons,

the Company is unable to address the probable significance of the unavailable information. The Company provides non-GAAP financial measures that it believes will be achieved, however it cannot accurately predict all of the components of the adjusted calculations and the U.S. GAAP measures may be materially different than the non-GAAP measures.

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 preliminary results for the fiscal year ended December 31, 2024 and the Company's expected financial outlook for 2025) and expectations for future growth, profitability, total revenue, royalty revenue, EBITDA, Adjusted EBITDA, and non-GAAP diluted earnings-per-share. 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, and potential approvals of new partnered or proprietary products, and the potential timing of these events. 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," "preliminary," "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 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.
