HALOZYME REPORTS THIRD QUARTER 2023 FINANCIAL AND OPERATING RESULTS
Royalty Revenue Increased 15% YOY to Record $114.4 million
Announces Acceleration into 2023 of Remaining $250M Share Repurchase through ASR
GAAP Diluted EPS of $0.61 and Non-GAAP Diluted EPS of $0.75 1
Maintained Revenue Guidance and Raised 2023 EBITDA Guidance to $430-$445 million and Non-GAAP EPS Guidance to $2.70-$2.80
SAN DIEGO, November 6, 2023 -- Halozyme Therapeutics, Inc. (NASDAQ: HALO) (“Halozyme” or the “Company”) today reported its financial and operating results for the third quarter ended September 30, 2023 and provided an update on its recent corporate activities and outlook.
“I am delighted that our strong operating performance and expense management throughout the year have resulted in an increase to EBITDA and non-GAAP EPS guidance. Today, we also announced an acceleration into this year of the remaining $250 million under the current approved $750 million share repurchase plan, authorized in 2021. This action is part of our disciplined and balanced approach to capital allocation and reflects our assessment that share repurchases today are a strong return on investment opportunity,” said Helen Torley, president and CEO of Halozyme. “Supporting our conviction in long-term revenue growth and durability, the third quarter was remarkable, with multiple, meaningful, de-risking events and progress for our upcoming series of Wave 3 potential product launches, projected for 2023-2025. I am also pleased with the progress in the quarter in advancing discussions on development of our HVAI.”
Recent Corporate Highlights:
•Announced an acceleration, into this year, of the remaining $250 million under the current approved $750 million share repurchase plan authorized in 2021. The Company intends to execute the $250 million share repurchase by entering into an accelerated share repurchase (“ASR”) transaction with a financial Institution, immediately, subject to market conditions.
•In August 2023, the Company announced positive results of a clinical study with its high-volume auto-injector demonstrating SC administration of 10 mL of a representative biologic product co-formulated with our ENHANZE® drug delivery technology in approximately 30 seconds. The results were presented at the 13 th annual Partnership Opportunities in Drug Delivery (“PODD”) conference in October 2023.

Recent Partner Highlights:
•In November 2023, Halozyme and Acumen entered into a global collaboration and non-exclusive license agreement that provides Acumen access to ENHANZE® technology for a single target. Acumen intends to explore the potential use of ENHANZE for ACU193, Acumen’s clinical stage monoclonal antibody candidate to target Amyloid-β Oligomers for the treatment of early Alzheimer’s disease.
•In October 2023, Bristol Myers Squibb reported positive topline results from the Phase 3 CheckMate-67T trial evaluating a SC formulation of Opdivo (nivolumab) with ENHANZE® in patients with advanced or metastatic clear cell renal cell carcinoma (“ccRCC”) who have received prior systemic therapy. The study met its co-primary pharmacokinetics (“PK”) endpoints and a key secondary endpoint.
•In September 2023, Chugai Pharmaceuticals, a member of the Roche Group, announced that it had obtained regulatory approval for Phesgo® from the Ministry of Health, Labour and Welfare (“MHLW”) in Japan. Halozyme is entitled to receive royalties for Phesgo® sales in Japan under its agreement with Roche.
•In September 2023, argenx announced the Committee for Medicinal Products for Human Use (“CHMP”) of the European Medicines Agency (“EMA”) has recommended European Commission (“EC”) approval of the SC injectable formulation of efgartigimod as an add on to standard therapy for the treatment of adult patients with generalized myasthenia gravis (“gMG”) who are anti-acetylcholine receptor (“AChR”) antibody positive. The EC is expected to make a decision on the argenx marketing authorization application within approximately 67 days following the CHMP recommendation.
•In September 2023, Zai Lab limited (argenx commercial partner for China) announced the Center for Drug Evaluation (“CDE”) of the National Medical Products Administration (“NMPA”) granted Breakthrough Therapy Designation for efgartigimod alfa injection (SC injection) (efgartigimod SC) for the treatment of patients with chronic inflammatory demyelinating polyneuropathy (“CIDP”). The Breakthrough Therapy Designation for efgartigimod SC was supported by data from both global and Chinese patients enrolled in the ADHERE study.
•In September 2023, Roche informed the Company that there will be a delay in the projected launch timing for Tecentriq® SC in the U.S. as a result of Roche’s need to update chemistry, manufacturing, and controls (“CMC”) processes for Tecentriq® SC. Roche expects these updates to be completed in 2023 to support a potential launch of Tecentriq® SC in the U.S. in 2024. There is no expected impact on ex-U.S. filings for Tecentriq® SC.
•In August 2023, Roche announced the approval of Tecentriq® SC with ENHANZE® by the Medicines and Healthcare products Regulatory Agency (“MHRA”) in Great Britain, triggering an $8.0 million milestone payment to Halozyme and the right to receive royalties on net product sales.
•In August 2023, ViiV initiated a Phase 2b study to evaluate the efficacy, safety, PK and tolerability of VH3810109 (N6LS) administered subcutaneously with ENHANZE® in combination with cabotegravir.
•In August 2023, ViiV achieved a development milestone, which triggered a $5 million milestone payment to Halozyme.
•In July 2023, argenx reported positive data from the ADHERE study evaluating VYVGART® Hytrulo with ENHANZE® in adults with CIDP. The study met its primary endpoint resulting in a 61% reduction in risk of relapse compared to placebo.
•In July 2023, Roche announced that the Phase III OCARINA II trial evaluating OCREVUS® (ocrelizumab) with ENHANZE® as a twice a year 10-minute SC injection met its primary and secondary endpoints in patients with relapsing forms of multiple sclerosis (“MS”) or primary progressive MS (“RMS” or “PPMS”).

Third Quarter 2023 Financial Highlights:
•Revenue was $216.0 million compared to $209.0 million in the third quarter of 2022. The 3% year-over-year increase was driven by growth in ENHANZE® revenue streams with an increase in royalty revenue and an increase in product sales as a result of an increase in bulk rHuPH20 sales driven by partner demand and continued growth in XYOSTED®, partially offset by in the timing of milestone revenue. Revenue for the quarter included $114.4 million in royalties, an increase of 15% 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 $54.8 million, compared to $47.3 million in the third quarter of 2022. The increase was driven by growth in proprietary product sales and bulk rHuPH20 demand.
•Amortization of intangibles expense was $20.3 million, compared to $27.2 million in the third quarter of 2022. The decrease was due to a remeasurement period adjustment of our acquired intangible assets recorded in the fourth quarter of 2022, partially offset by an impairment charge of $2.5 million to fully impair the TLANDO® product rights intangible asset as a result of the license agreement termination notice provided to Lipocine in September 2023.
•Research and development expense was $17.3 million, compared to $16.7 million in the third quarter of 2022. Selling, general and administrative expense was $35.3 million, compared to $34.5 million in the third quarter of 2022. The increases were primarily due to an increase in compensation expense.
•Operating income was $88.3 million, compared to operating income of $83.3 million in the third quarter of 2022.
•Net Income was $81.8 million, compared with net income of $61.6 million in the third quarter of 2022.
•EBITDA was $124.6 million, compared with EBITDA of $109.8 million in the third quarter of 2022. Adjusted EBITDA was $114.9 million, compared with Adjusted EBITDA of $110.2 million in the third quarter of 2022.1
•Earnings per Share: GAAP diluted earnings per share was $0.61, compared with $0.44 in the third quarter of 2022. Non-GAAP diluted earnings per share was $0.75, compared with $0.74 in the third quarter of 2022.1
•Cash, cash equivalents and marketable securities were $483.3 million on September 30, 2023, compared to $362.8 million on December 31, 2022. The increase was primarily due to the cash provided by operating activities, partially offset by repurchase of common stock for $150.0 million in the first quarter of 2023.
Financial Outlook for 2023
The Company is raising its EBITDA and non-GAAP EPS guidance ranges to reflect strong expense management. For the full year 2023, the Company now expects:
•Total revenue of $825 million to $845 million, representing growth of 25% to 28% over 2022 total revenue primarily driven by continued strength in Wave 2 products, including DARZALEX® SC and Phesgo® utilizing ENHANZE®, as well as full year auto-injector royalty and product contribution. The Company expects revenue from royalties of $445 million to $455 million, representing growth of 23% to 26%.
•EBITDA of $430 million to $445 million, representing growth of >30% over 2022. EBITDA excludes the impact of amortization costs related to the Antares Pharma acquisition.1
•Non-GAAP diluted earnings per share of $2.70 to $2.80, representing growth of 22% over 2022.1 The Company’s earnings per share guidance does not consider the impact of potential future share repurchases.

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 discount, intangible asset amortization, transaction costs for business combinations, realized gains or losses on marketable security sales and certain adjustments to income tax expense. The Company calculates EBITDA excluding interest, taxes, depreciation and amortization. The Company calculates adjusted EBITDA excluding transaction costs for business combinations. 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 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 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 2023) and expectations for future growth, achieving operational goals, profitability, return on investment, revenues (including royalty, milestone and product sales revenue), 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 and potential approvals of new partnered or proprietary products and the Company’s development and partnership potential of a high volume auto-injector. 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, 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 (including its high volume auto-injector), 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.
