SAN DIEGO, Feb. 17, 2026 /PRNewswire/ -- Halozyme Therapeutics, Inc. (NASDAQ: HALO) ("Halozyme" or the "Company") today reported its financial and operating results for the full year and fourth quarter ended December 31, 2025, and provided an update on its recent corporate activities.

"2025 was a pivotal year for Halozyme as we delivered record total revenue of $1.4 billion, which was the result of continued growth in our ENHANZE business. In addition, we expanded our drug delivery technology portfolio with two acquisitions. Three ENHANZE-enabled blockbusters, DARZALEX SC, Phesgo and VYVGART Hytrulo, drove royalty revenue growth of 52%, reaching a record $868 million in 2025. In the year, we also expanded our ENHANZE opportunities, adding three new collaboration and licensing agreements with Takeda, Merus and Skye Bioscience and gained one new target nomination from Roche. Furthermore, Janssen expanded the global reach of ENHANZE with approvals in the U.S., China and Japan for Rybrevant SC and new indication approvals in front line settings for DARZALEX Faspro. In parallel, we broadened our drug delivery portfolio with the acquisitions of the Hypercon technology and Surf Bio's hyperconcentration technology, which meaningfully expand, diversify and extend our long-term royalty opportunity into the mid-2040s," said Dr. Helen Torley, President and Chief Executive Officer.

Dr. Torley continued, "As we look ahead, our long-term outlook reflects the strong momentum and opportunity we have built through a broader drug delivery portfolio and offering to the biopharma industry. With royalty revenue projected to exceed $1 billion in 2026 and a clear line of sight to more than $2 billion in total revenue by 2028, Halozyme is entering its next phase of growth with strong conviction. Our projected 22% to 30% total revenue growth in 2026, combined with an expanding development pipeline with six projected new ENHANZE and two Hypercon development program starts, plus plans to sign three or more ENHANZE and Hypercon partnerships in 2026, all reinforce the durability of our revenue. With our strong cash generation and a diversified set of high-value royalty drivers, we remain focused on delivering sustained long-term value for shareholders."

Full Year and Fourth Quarter 2025 Financial Highlights:

• Total revenue for the full year was $1,396.6 million, compared to $1,015.3 million in 2024. The 38% year-over-year increase was primarily driven by royalty revenue growth and an increase in product sales. Revenue included $867.8 million in royalties, an increase of 52% compared to $571.0 million in 2024, primarily driven by continued sales uptake of ENHANZE^® partner products that have launched since 2020, predominantly by VYVGART^® Hytrulo by argenx, DARZALEX^® SC by Janssen and Phesgo^® by Roche in all geographies.
• Cost of sales for the full year was $228.8 million, compared to $159.4 million in 2024. The increase in cost of sales was primarily due to an increase in product sales and labor allocation initiatives.
• Amortization of intangibles expense for the full year was $76.7 million, compared to $71.0 million in 2024. The increase in amortization of intangibles expense was due to the acquisition of Elektrofi in November 2025.
• Research and development expense for the full year was $81.5 million, compared to $79.0 million in 2024. The increase was primarily due to the acquisition of Elektrofi and Surf Bio, partially offset by lower compensation expense driven by resource optimization, labor allocation initiatives, and timing of planned investments in ENHANZE^® related to the development of our new high-yield rHuPH20 manufacturing process.
• Selling, general and administrative expense for the full year was $207.1 million, compared to $154.3 million in 2024. The increase was primarily due to an increase in consulting and professional service fees, including litigation costs incurred in connection with a patent infringement litigation case, diligence and transaction-related costs incurred in support of the acquisition of Elektrofi and Surf Bio, and an increase in compensation expense.
• Net income for the full year was $316.9 million, compared to $444.1 million in 2024. Net Income included acquired in-process research and development ("IPR&D") expense of $284.9 million related to the Surf Bio acquisition in the fourth quarter of 2025.
• Adjusted EBITDA for the full year was $657.6 million, compared to $632.2 million in 2024.^1,2
  Adjusted EBITDA included acquired IPR&D expense of $284.9 million related to the Surf Bio acquisition in the fourth quarter of 2025.
• GAAP diluted earnings per share for the full year was $2.56, compared to $3.43 in 2024. Non-GAAP diluted earnings per share was $4.15, compared to $4.23 in 2024.^1,2
  GAAP and non-GAAP diluted earnings per share included an unfavorable impact of approximately $2.30 per share related to acquired IPR&D expense for the Surf Bio acquisition in the fourth quarter of 2025.
• Total revenue in the fourth quarter was $451.8 million, compared to $298.0 million in the fourth quarter of 2024. The 52% year-over-year increase was primarily driven by royalty revenue growth and an increase in product sales. Revenue included $258.0 million in royalties, an increase of 51% compared to $170.4 million in the fourth quarter of 2024, primarily driven by continued sales uptake of ENHANZE^® partner products that have launched since 2020, predominantly by VYVGART^® Hytrulo by argenx, DARZALEX^® SC by Janssen and Phesgo^® by Roche in all geographies.
• Net loss in the fourth quarter was $141.6 million, compared to net income of $137.0 million in the fourth quarter of 2024. Net loss included acquired IPR&D expense of $284.9 million related to the Surf Bio acquisition in the fourth quarter of 2025.
• Adjusted EBITDA in the fourth quarter was $21.9 million, compared to $195.8 million in the fourth quarter of 2024.^1,2
  Adjusted EBITDA included acquired IPR&D expense of $284.9 million related to the Surf Bio acquisition in the fourth quarter of 2025.
• GAAP diluted loss per share in the fourth quarter was $1.20, compared to GAAP diluted earnings per share $1.06 in the fourth quarter of 2024. Non-GAAP diluted loss per share was $0.24 compared to Non-GAAP diluted earnings per share of $1.26 in the fourth quarter of 2024.^1,2
  GAAP and non-GAAP diluted loss per share in the fourth quarter of 2025 included an unfavorable impact of $2.42 per share related to acquired IPR&D expense for the Surf Bio acquisition in the fourth quarter of 2025.
• Cash, cash equivalents, restricted cash and marketable securities were $145.4 million on December 31, 2025, compared to $596.1 million on December 31, 2024. The decrease was primarily driven by cash used for the Elektrofi and Surf Bio acquisitions and share repurchases, partially offset by the net proceeds from issuance of convertible notes and 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, 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, severance 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. 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, severance 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 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 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 the Company's expected financial outlook for 2026) and expectations for future growth, profitability, revenue durability, total revenue, royalty revenue, royalty revenue duration, EBITDA, Adjusted EBITDA, and non-GAAP diluted earnings-per-share, and shareholder value.  Forward-looking statements also include future plans, objectives, expectations and intentions related to the acquisitions of Elektrofi and Surf Bio, such acquisitions' expected impact and contributions to the Company's and combined group's operations and financial results (including potential development and commercialization of partnered products and timing related to these events), as well as the expected benefits of the acquisitions. Forward-looking statements related to Elektrofi's and Surf Bio's intellectual property include expectations for length of patent terms and patent expirations and the expected impact such patents may have on the duration, durability and amounts of future royalty payments the Company may receive from licensing such intellectual property. 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 advancement of partnered development programs, regulatory submissions and product launches, the size and growth prospects of our partners' drug franchises, potential new or expanded collaborations and collaborative targets, 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 uncertainties concerning future matters such as market conditions, changes in domestic and foreign business, changes in the competitive environment in which the Company operates,  the expected benefits of its acquisitions of Elektrofi and Surf Bio, 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 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.
