• Increased pressure from private payers (insurers, PBMs, GPOs) seeking to reduce drug costs through higher discounts, rebates, and limited patient access.
• Potential for lawsuits or insurer actions challenging the legality of co-pay coupon programs.
• Risks related to incorrect reporting of pricing data, which could lead to substantial fines, penalties, or additional rebates.
• Potential for delays in regulatory approval and increased costs due to workforce reductions at federal health agencies (e.g., FDA) and changes in U.S. trade policy, including tariffs.

Future Outlook

The company expects royalty revenue to continue growing due to anticipated increases in partner product sales of DARZALEX SC, Phesgo, and VYVGART SC, as well as sales from recently launched ENHANZE partner products like TECENTRIQ SC, OCREVUS SC, Opdivo SC, and RYBREVANT SC. Modest price erosion is anticipated to continue on earlier launched ENHANZE partner products, Herceptin and MabThera. Product sales of bulk rHuPH20 and device partnered products are expected to fluctuate based on partner needs. Revenues from upfront license fees, target election fees, and event-based payments are expected to fluctuate based on partners' ability to meet clinical, regulatory, and event-based milestones, and the company's ability to secure new collaborative agreements. The company believes its current cash, cash equivalents, and marketable securities will be sufficient to fund operations for at least the next 12 months and plans to fund future operations through existing cash, anticipated revenues, and potential future financing activities.

Industry Context

Halozyme's strong performance, particularly in royalties, highlights the growing trend towards subcutaneous drug delivery in the biopharmaceutical industry. The ENHANZE technology's ability to convert intravenous (IV) therapies to more convenient subcutaneous (SC) formulations addresses a key patient and healthcare provider need for reduced treatment burden and potentially home administration. The numerous recent regulatory approvals for ENHANZE-enabled products across oncology, immunology, and neurology underscore the broad applicability and commercial success of this platform. The ongoing patent litigation with Merck regarding MDASE technology reflects the intense competition and importance of intellectual property in the drug delivery space. The industry is also navigating evolving healthcare pricing policies, such as the Inflation Reduction Act, which could impact future revenue streams for combination therapies.

Comparison to Industry Standards

• Halozyme's ENHANZE technology, enabling rapid subcutaneous delivery, directly competes with traditional intravenous administration methods by offering improved patient convenience and reduced treatment times. For example, Herceptin SC is administered in 2-5 minutes compared to 30-90 minutes for IV, and DARZALEX FASPRO in 3-5 minutes versus multi-hour IV infusions. SC amivantamab reduced administration time to approximately five minutes from five hours for the first IV infusion, and showed a five-fold reduction in infusion-related reactions.
• The company's partnerships with major pharmaceutical companies like Roche, Janssen, Takeda, Pfizer, AbbVie, Eli Lilly, BMS, and argenx demonstrate its position as a leading technology provider in the drug delivery sector. The approval of 10 commercial products utilizing ENHANZE technology, including key oncology and immunology drugs, indicates a high success rate for its licensed platform compared to typical early-stage biotech licensing models.
• The approval of VYVGART SC (efgartigimod) for self-injection, similar to other self-administered biologics, aligns with the industry trend towards empowering patients with more flexible treatment options, including home administration.
• The patent infringement lawsuit against Merck regarding Keytruda SC highlights the competitive landscape in drug delivery, where companies like Halozyme protect their proprietary technologies against potential infringers, similar to other intellectual property disputes seen with companies like Amgen (e.g., biosimilar litigation) or AbbVie (Humira patent thicket).

Legal Proceedings

• Filed a patent infringement lawsuit against Merck Sharp & Dohme Corp. in the U.S. District Court in New Jersey in April 2025, alleging infringement of MDASE SC delivery technology by Merck's SC Keytruda. The company is seeking damages and injunctive relief.
• The Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office has instituted post-grant reviews brought by Merck challenging the validity of certain U.S. patents covering MDASE technology.
• Opposition Division of the European Patent Office revoked two of Janssen's co-formulation patents for DARZALEX (daratumumab) SC in March 2023 and October 2024, which could result in permanent loss of contested patent rights if appeals fail.

Stakeholder Impact

• **Shareholders**: Positive impact due to significant increases in net income and EPS, strong royalty growth, and ongoing share repurchase programs, which enhance shareholder value.
• **Patients**: Improved patient experience and reduced treatment burden through rapid subcutaneous delivery of high-dose, high-volume injectable biologics, potentially enabling home administration for certain therapies.
• **Partners (Biopharmaceutical Companies)**: Continued successful development and commercialization of ENHANZE-enabled products, leading to expanded market reach and potentially extended patent life for their proprietary drugs.
• **Employees**: Stable employment and potential for growth given the company's strong financial performance and ongoing R&D activities, though resource optimization initiatives may impact some roles.
• **Creditors**: Strong financial health and cash flow generation provide confidence in the company's ability to meet its debt obligations.

Next Steps

• Continue to monitor the patent infringement lawsuit against Merck Sharp & Dohme Corp. regarding MDASE SC delivery technology.
• Evaluate the full impact of the One Big Beautiful Bill Act (OBBBA) on consolidated financial statements and related disclosures, applicable from Q3 2025.
• Monitor the final CMS guidance regarding IRA price controls for Part B combination therapies with two active ingredients.
• Continue to fund operations with existing cash resources and anticipated revenues from collaborative agreements.
• Potentially pursue new collaborative agreements, expansions of existing relationships, or other financing vehicles to raise additional capital.
• Continue share repurchases under the authorized $750 million program.
