Removed
If proprietary or partnered product candidates are approved for commercialization but do not gain market acceptance resulting in commercial performance below that which was expected or projected, our business may suffer.
Added
For example, we acquired Antares (in May 2022), Elektrofi (in November 2025), and Surf Bio (in December 2025), as a means to grow and diversify the sources of our revenues.
Removed
Customer contracts, such as with group purchasing organizations and hospital formularies, will often not offer contract or formulary status without either the lowest price or substantial proven clinical differentiation.
Added
Workforce reduction at federal agencies and changes in U.S. trade policy, including tariffs and potential countermeasures by trading partners, could delay regulatory approval and increase our or our partners’ costs, disrupt global supply chains and have a material adverse impact on our business, financial condition, and results of operations.
Removed
For example, in November 2020, former President Trump announced the interim final rule to implement the Most Favored Nations drug pricing model seeking to tie Medicare payment rates to an international index price. This final rule was subsequently rescinded by CMS.
Added
The current federal government administration has increased, and has indicated a willingness to continue to increase, the use of tariffs by the U.S. to accomplish certain policy goals.
Removed
For example, in July 2019, the Senate Finance Committee advanced a bill that in part would penalize pharmaceutical manufacturers for increasing drug list prices covered by Medicare Part B and Part D, faster than the rate of inflation, and cap out-of-pocket expenses for Medicare Part D beneficiaries.
Added
Such tariffs and any countermeasures by the U.S.’ trading partners could increase the cost of raw materials, components and finished goods necessary for our or our partners’ operations, disrupt global supply chains, create additional operational challenges and cause widespread uncertainty in the financial markets.
Removed
Furthermore, individual states are considering proposed legislation and have become increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access, importation from other countries and bulk purchasing.
Added
Further, it is possible the administration’s trade policy changes directly impacting the biopharmaceutical industry and related uncertainty about such policy changes could increase volatility in the market valuation of companies in the healthcare industry.
Added
Because of these dynamics, we cannot predict the impact of any future changes to international trading relationships or the ultimate impact recently adopted tariff policies will have on our business. Such changes in tariffs and trade regulations could have a material adverse effect on our financial condition, results of operations and cash flows.
Added
Additionally, recent widespread reductions in workforce at federal health agencies, including the FDA, could have a negative impact on the speed with which our products or devices and our partners’ products are reviewed and approved for commercialization.
Added
We rely on many third parties to source active pharmaceutical ingredient and drug products, manufacture and assemble our devices, distribute finished products and provide various logistics activities in order to manufacture and sell our partnered and proprietary products.
Added
Our ability to make payments on our existing or any future debt will depend on our future operating performance and ability to generate cash and may also depend on our ability to obtain additional debt or equity financing. It will also depend on financial, business or other factors affecting our operations, many of which are beyond our control.
Added
In addition, our proprietary or partnered product candidates will be restricted to the labels approved by FDA and applicable regulatory bodies, and these restrictions may limit the marketing and promotion of the ultimate products. If the approved labels are restrictive, the sales and marketing efforts for these products may be negatively affected.
Added
Because some of our and our partners’ products and product candidates are considered to be drug/device combination products, the regulatory approval and post-approval requirements that we and they are required to comply with can be more complex.
Added
For example, in April 2025 we filed a patent infringement lawsuit against Merck Sharp & Dohme Corp. (“Merck”) in the U.S. District Court in New Jersey alleging that Merck is using Halozyme’s patented MDASE™ subcutaneous drug delivery technology to develop Subcutaneous (“SC”) Keytruda. We are seeking damages and injunctive relief to stop Merck’s infringement of Halozyme’s MDASE™ intellectual property.
Added
Patent infringement litigation can be costly, take a long period of time to resolve and involves uncertainties beyond our control. We can offer no assurance as to developments related to the patent infringement litigation, the outcome of the litigation or any remedies that could be awarded in connection with the litigation.
Added
In May 2025, an Executive Order was issued calling on pharmaceutical manufacturers to voluntarily reduce the prices of medicines in the U.S. The Executive Order directs the Secretary of the Department of Health and Human Services (“HHS”) to communicate Most Favored Nations (“MFN”) price targets to pharmaceutical manufacturers to bring prices in line with comparably developed nations.
Added
The Executive Order further provides that if such actions do not lower the costs of pharmaceuticals, the Secretary of the HHS shall pursue other actions, including proposing a rulemaking that imposes MFN pricing in the U.S.
Added
In May 2025, CMS issued draft guidance for 2028 price controls under the IRA that creates uncertainty as to whether combination therapies, such as our partners’ ENHANZE products, will be protected from IRA price negotiations for thirteen years following approval of the combination therapy.
Added
In September 2025, following a review of comments submitted in response to the draft guidance, CMS issued final guidance for 2028 price controls under the IRA, indicating that due to the complexity and scope of this issue, CMS believes additional time is necessary to develop objective policy criteria if CMS were to finalize such a policy, and thus did not make a change to the fixed combination drug policy.
Added
CMS indicated it intends to continue to consider the appropriate policy to implement in rulemaking beginning in initial price applicability year 2029.
Added
For initial price applicability year 2028, CMS will maintain its approach to fixed combination drugs which states that if a drug is a fixed combination drug with two or more active moieties / active ingredients, the distinct combination of active moieties / active ingredients will be considered as one active moiety / active ingredient for the purpose of identifying potential qualifying single source drugs.
Added
A product containing only one (but not all) of the active moieties / active ingredients that is offered by the same New Drug Application / Biologics License Application holder will not be aggregated with the formulations of the fixed combination drug and will be considered a separate potential qualifying single source drug.
Added
Section 30.1 of this final guidance details how CMS intends to treat fixed combination drugs and gives an example to illustrate the application. In this dynamic environment, we are unable to predict which or how many federal policy, legislative or regulatory changes that impact us may ultimately be enacted.
Added
Additionally, artificial intelligence (“AI”) based software is increasingly being used in the biopharmaceutical industry including by companies with which we compete. We are increasing the use of AI tools and technology and intend to integrate AI more broadly in our operations with the goal of increasing operational efficiencies, improve cycle times and improve decision-making, thus strengthening our ability to compete.
Added
The integration of third-party AI technology with our operations relies on certain safeguards implemented by the third-party developers of the underlying AI technology including those related to security and the accuracy, bias and other variables of the data, and these safeguards may not be sufficient to mitigate the risks associated with the use of AI.
Added
Furthermore, the use of AI based software may result in cybersecurity incidents and lead to the inadvertent release of personal information or other confidential proprietary information, which may impact our ability to realize the benefit of our intellectual property. Governments have passed laws and are likely to pass additional laws regulating the use of generative AI.
