SAN DIEGO, Aug. 6, 2026 /PRNewswire/ -- Halozyme Therapeutics, Inc. (Nasdaq: HALO) ("Halozyme" or the "Company") today reported its financial and operating results for the second quarter ended June 30, 2026, and provided an update on its recent corporate activities.

"We delivered another quarter of strong performance, with multiple proof points demonstrating the attractive features of ENHANZE as a compounding platform engine: repeatability of success, scalability, diversification and durability of revenues," said Dr. Helen Torley, President and Chief Executive Officer. "Total revenue increased 48% year-over-year to $481 million, royalty revenue increased 50% to $308 million and adjusted EBITDA grew 46% to $329 million, reflecting the strength of our differentiated royalty business. Based on these record results, we are raising our full year 2026 financial guidance."

"Importantly, we are delivering on both our near-term and long-term growth objectives. The ENHANZE value proposition is attracting new partners and additional products from our current partners. We expanded our royalty revenue opportunity by signing five new ENHANZE and Hypercon collaborations through July, including agreements with Vertex, Oruka, GSK, Incyte and an undisclosed partner who is the first to license ENHANZE for a nucleic acid therapeutic. We have also demonstrated our commitment to returning significant capital to shareholders, repurchasing $333 million of shares in 2Q 2026, at an average price of $69.30. Overall, these results illustrate our continued ability to create multiple waves of revenue opportunities that will drive long-term shareholder value," concluded Dr. Torley.

Second Quarter 2026 Financial Highlights:

• Total revenue was $481.0 million, compared to $325.7 million in the second quarter of 2025. The 48% year-over-year increase was primarily driven by royalty revenue growth and an increase in product sales. Revenue included $307.7 million in royalties, an increase of 50% compared to $205.6 million in the second quarter of 2025, primarily driven by continued sales uptake of ENHANZE^® partner products that have launched since 2020, predominantly by VYVGART^® Hytrulo by argenx and DARZALEX^® SC Janssen in all geographies and contributions from other recently launched products.
• Cost of sales was $79.2 million, compared to $46.4 million in the second quarter of 2025. The increase in cost of sales was primarily due to an increase in bulk rHuPH20 sales.
• Amortization of intangibles expense was $29.5 million, compared to $17.8 million in the second quarter of 2025. The increase in amortization of intangibles expense was due to the acquisition of Elektrofi, Inc. ("Elektrofi") in November 2025.

The increase was primarily due to an increase in consulting and professional service fees, including litigation costs incurred in connection with patent infringement litigation, the acquisition of Elektrofi and Surf Bio, and an increase in compensation expense.
• Operating income was $287.7 million, compared to $202.4 million in the second quarter of 2025.

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, 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 items, if any, such as changes in contingent liabilities, inventory adjustments, impairment charges, transaction costs for business combinations and share-based compensation acceleration expenses, intellectual property litigation costs, inducement expenses related to convertible notes, 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 per share. 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, impairment charges, transaction costs for business combinations and share-based compensation acceleration expenses and intellectual property litigation costs. Reconciliations between GAAP and Non-GAAP financial measures are included at the end of this press release. The Company does not provide reconciliations for 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 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.

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 uncertainties concerning future matters such as unexpected results or delays in the Company's repurchases of the Company's shares under the share repurchase program, market conditions, changes in domestic and foreign business, changes in the competitive environment in which the Company operates, unexpected early expiration or termination of the patent terms for the Company's drug delivery technologies, 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, including under the headings "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations". Except as required by law, the Company undertakes no duty to update forward-looking statements to reflect events after the date of this release.
