"I am pleased to announce our new $1 billion share repurchase program and that we project to repurchase at least $400 million in 2026, which is a reflection of our strong cash generation and confidence in the long-term value and durability of our business. We started 2026 with exceptional momentum, highlighted by three new recent collaboration and licensing agreements with Vertex, Oruka and GSK, demonstrating the strong interest in Hypercon and ENHANZE and showcasing the real potential to exceed our goal of three new SC delivery platform deals this year. The two Hypercon multi-target agreements confirm the strong interest of biopharma companies to reduce injection volume through hyperconcentration and allow more flexible administration in the home. Our new multi-target agreement with GSK represents a significant opportunity for ENHANZE with multiple promising oncology targets, including its first potential application with antibody drug conjugates. This momentum creates durable new royalty opportunity beginning in the 2030s and extending to at least the mid-2040s," said Dr. Helen Torley, President and Chief Executive Officer of Halozyme.

"The growing number of indications for our approved products and new Phase 3 data milestones represent increased opportunity for ENHANZE. Most recently, VYVGART Hytrulo was FDA-approved for all serotypes of generalized myasthenia gravis (gMG), representing a significant expansion of addressable patients. The VYVGART Hytrulo opportunity is further extended with positive Phase 3 data in ocular myasthenia gravis, increasing the MG addressable market by an additional 7,000 patients in the U.S. alone. Additionally, DARZALEX Faspro gained its 12th and 13th approved indications and expanded further in newly diagnosed and early second line multiple myeloma patients, the two largest, longer-duration of treatment patient populations. Takeda also announced positive Phase 2/3 data for its 20% immunoglobulin TAK-881 in patients with primary immune deficiency, creating the potential for the 11th ENHANZE product launch."

"Our opportunity with ENHANZE was further enhanced in the quarter by two new Phase 1 study starts, increasing the number of ENHANZE products in development to nine, well on our way to the expected 13 ENHANZE products in development by year-end 2026. We project these ENHANZE products have the potential for approvals beginning in 2029+, creating a new wave of royalty revenue. The five signed Hypercon agreements, which include the opportunity for 17 targets to be developed, with first approvals projected in the 2030/2031 time period represents a third exciting wave of new royalty revenue opportunity. This continued performance and progress resulted in strong first quarter financial results and we are pleased to reaffirm our 2026 outlook, including expectations for ENHANZE royalty revenue to exceed $1 billion for the full year," Dr. Torley concluded.

First Quarter 2026 Financial Highlights:
•Total revenue was $376.7 million, compared to $264.9 million in the first quarter of 2025. The 42% year-over-year increase was primarily driven by royalty revenue growth and an increase in product sales. Revenue included $240.7 million in royalties, an increase of 43% compared to $168.2 million in the first quarter of 2025, primarily driven by continued sales uptake of ENHANZE partner products that have launched since 2020, predominantly DARZALEX SC by Janssen, VYVGART Hytrulo by argenx and Phesgo by Roche in all geographies and contributions from other recently launched products.
•Cost of sales was $79.2 million, compared to $48.4 million in the first 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 first quarter of 2025. The increase in amortization of intangibles expense was due to the acquisition of Elektrofi, Inc. ("Elektrofi") in November 2025.
