SAN DIEGO, October 31, 2024 -- Halozyme Therapeutics, Inc. (NASDAQ: HALO) (“Halozyme” or the “Company”) today reported its financial and operating results for the third quarter ended September 30, 2024, and provided an update on its recent corporate activities and outlook.

“Our robust third quarter financial results highlight the strong execution and accelerating momentum we have across our business and exceeded expectations with total revenue growth of 34% and adjusted EBITDA growth of 60%. Based on the strong performance year-to-date, we have raised our 2024 guidance ranges and expect the advancement of our ENHANZE pipeline and new nominations from two global licensing agreements to support our future growth trajectory,” said Dr. Helen Torley, president and chief executive officer of Halozyme. “In the quarter, the announcement of two highly anticipated partner approvals in the U.S. for Roche’s TECENTRIQ HYBREZA and OCREVUS ZUNOVO reinforces ENHANZE’s track record of 100% phase 3 study and subsequent regulatory success. The new nominations for ENHANZE from argenx, for a total of six targets, and ViiV Healthcare, for an additional undisclosed target, further demonstrate the value of our leading technology for rapid, large volume subcutaneous delivery.”

•In October 2024, argenx initiated two studies evaluating VYVGART® Hytrulo with ENHANZE®, a Phase 3 study for adult patients with ocular myasthenia gravis (“oMG”) and a Phase 2 study for kidney transplant recipients with antibody mediated rejection (“AMR”).

•In October 2024, Janssen announced the European Commission approved DARZALEX® SC for the treatment of patients newly diagnosed with multiple myeloma (“NDMM”) who are eligible for autologous stem cell transplant (“ASCT”) in combination with bortezomib, lenalidomide, and dexamethasone (“D-VRd”).

•In September 2024, argenx expanded its global collaboration and license agreement nominating four additional targets that provides them exclusive access to our ENHANZE® drug delivery technology for a total of six targets. Under the terms of the expanded exclusive agreement, we received upfront payments of $7.5 million per target nomination for a total of $30.0 million. argenx is obligated to make future milestone payments of up to $85.0 million per new nominated target, subject to achievements of specified development, regulatory and sales-based milestones. We are also entitled to receive royalties on net sales of commercialized products with our ENHANZE® technology.

•In September 2024, ViiV expanded its global collaboration and license agreement providing ViiV the ability to exclusively access our ENHANZE® drug delivery technology for one additional undisclosed target.

•In September 2024, Roche announced the U.S. Food and Drug Administration (“FDA”) approved OCREVUS ZUNOVO™ with ENHANZE® as a twice a year ten-minute subcutaneous (“SC”) injection for the treatment of relapsing multiple sclerosis and primary progressive multiple sclerosis.

•In September 2024, Roche announced the FDA approved TECENTRIQ HYBREZA™ with ENHANZE® for all approved adult indications of intravenous (“IV”) TECENTRIQ® and was made available to patients, resulting in a $12.0 million milestone payment.

•In September 2024, Janssen announced the submission of a supplemental Biologic License Application to the FDA for approval of a new indication of DARZALEX FASPRO® in combination with D-VRd for the treatment of adult patients with NDMM for whom ASCT is deferred or who are ineligible for ASCT.

•Revenue was $290.1 million, compared to $216.0 million in the third quarter of 2023. The 34% year-over-year increase was primarily driven by royalty revenue growth and an increase in milestone revenue. Revenue for the quarter included $155.1 million in royalties, an increase of 36% compared to $114.4 million in the third quarter of 2023, primarily attributable to increases in revenue of DARZALEX® SC and Phesgo®, and the prior year launch of VYVGART® Hytrulo.

•Cost of sales was $49.4 million, compared to $54.8 million in the third quarter of 2023. The decrease was primarily due to lower device and bulk rHuPH20 sales.

•Amortization of intangibles expense was $17.8 million, compared to $20.3 million in the third quarter of 2023. The decrease was primarily due to an impairment charge of $2.5 million recognized in the prior year to fully impair the TLANDO® product rights intangible asset.

•Research and development expense was $18.5 million, compared to $17.3 million in the third quarter of 2023. The increase was primarily due to increased compensation expense.

•Selling, general and administrative expense was $41.2 million, compared to $35.3 million in the third quarter of 2023. The increase was primarily due to increased compensation expense and consulting and professional service fees.

•Operating income was $163.2 million, compared to $88.3 million in the third quarter of 2023.

•Net Income was $137.0 million, compared to $81.8 million in the third quarter of 2023.

•Cash, cash equivalents and marketable securities were $666.3 million on September 30, 2024, compared to $336.0 million on December 31, 2023. The increase was primarily a result of cash generated from operations.

The Company is raising its financial guidance for 2024. For the full year 2024, the Company expects:

•Total revenue of $970 million to $1,020 million, representing growth of 17% to 23% over 2023 total revenue primarily driven by increases in royalty revenue, collaboration revenue and growth in product sales from XYOSTED®. Revenue from royalties of $550 million to $565 million, representing growth of 23% to 26% over 2023.

•Adjusted EBITDA of $595 million to $625 million, representing growth of 40% to 47% over 2023.

•Non-GAAP diluted earnings per share of $4.00 to $4.20, representing growth of 44% to 52% over 2023. The Company’s earnings per share guidance does not consider the impact of potential future share repurchases.

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 discounts, intangible asset amortization, one-time 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 such as changes in contingent liabilities and inventory adjustments. 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. 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.

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 2024) 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,” “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.
