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) 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 discount, debt extinguishment expense, intangible asset amortization, changes in contingent liabilities, transaction costs for business combinations and certain adjustments to income tax expense. 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 contingent liabilities, 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 Halozyme'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. Halozyme 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 expected future financial performance (including the Company's financial outlook for 2022 and 2023) and expectations for future growth, profitability, total revenue and royalty revenue, net income, EBITDA and earnings-per-share and to repurchase shares under its share repurchase program and expand the Company's platform through potential acquisitions. 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 larger volumes of injectable medications through subcutaneous delivery and the Company's plans to develop a large volume auto-injector. 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 readouts, regulatory submissions and product launches, the size and growth prospects of our partners' drug franchises, potential new collaborations and collaborative targets, potential partnership to test our planned large volume auto-injector and regulatory review and potential approvals of new partnered or proprietary products. These forward-looking statements are typically, but not always, identified through use of the words "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 or planned platform expansion, unexpected results or delays in the growth of the Company's business including any delays in entering into new collaboration agreements, or in the development, regulatory review or commercialization of the Company's partnered or proprietary products, unexpected delays in the Company's plans to develop a large volume auto-injector, including any potential delays caused by the current COVID-19 global pandemic, 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 recently filed Annual Report on Form 10-K and Quarterly Reports on Form 10-Q filed with the Securities and Exchange Commission.
