Executive summary

Jazz Pharmaceuticals Q4 FY25 — Record Revenue and Strategic Focus on Rare Disease

Jazz Pharmaceuticals delivered record financial performance in Q4 and full-year 2025, driven by strong growth in Xywav, Epidiolex, and the successful launch of Modeyso. The company is sharpening its strategic focus on rare disease, leveraging its proven capabilities and pursuing business development opportunities to drive durable growth. While facing evolving competitive dynamics in the sleep market, Jazz remains confident in its differentiated product portfolio and robust pipeline.

Highlights

5
  • Achieved record total revenue of $4.3 billion for FY25, marking the 21st consecutive year of topline growth.

  • Fourth quarter revenue reached an all-time high of $1.2 billion, reflecting 10% year-over-year growth.

  • Modeyso generated $48 million in revenue in 2025, following its launch in August.

  • Xywav revenue grew 12% to approximately $1.7 billion for FY25, with 500 net patient adds in Q4 and over 2,000 in FY25.

  • Epidiolex achieved blockbuster status with $1.1 billion in revenue, up 9% year-over-year, driven by 7% volume growth.

Concerns

3
  • Rare Sleep revenue is expected to modestly decrease in 2026 to $1.8 billion-$1.9 billion, primarily due to generic Xyrem and Hikma AG revenue.

  • Non-GAAP adjusted gross margin is guided to 90%-91% for 2026, a slight decline from 2025 due to higher royalties and potential tariffs.

  • Decision to stop development of JZP441 and end partnership with Sumitomo due to continued assessment of the molecule.

Deals & partnerships

Chimerix Acquisition of Chimerix, securing Modeyso.

Acquisition completed in April 2025, leading to rapid approval and launch of Modeyso.

Undisclosed Sale of Priority Review Voucher. $200 million

Announced in January 2026, the sale generated $200 million in gross proceeds.

Sumitomo Partnership for JZP441 development.

Partnership ended due to the decision to stop development of JZP441 based on continued assessment of the molecule.

Boehringer Ingelheim Collaboration to combine zanidatamab with zongertinib.

A Phase I trial was recently initiated to explore the combination in metastatic HER2-positive breast cancer and other potential tumor types.

Risks & headwinds

Evolving Sleep Market Competition FY26, particularly H2 2026

Rare Sleep revenue guidance of $1.8 billion to $1.9 billion for FY26 (down from $2.01 billion in FY25); Xyrem revenue of $146 million in FY25 expected to further reduce.

Mitigation:Focus on Xywav's differentiated low-sodium profile and IH indication; strong payer contracts in place; physicians' motivation to prescribe low-sodium option despite step edits; continued disease awareness campaigns.

Higher Royalties and Tariffs Impacting Gross Margin FY26

Non-GAAP adjusted gross margin guidance of 90%-91% for FY26, a slight decline from 2025.

Mitigation:Offset by productivity efforts across global commercial organization, lower facilities expenses, and lower legal fees, as reflected in stable SG&A guidance.

Generic High Sodium Oxybate Entry FY26, with impact building in H2

Two generic high sodium oxybate products entering the market; modest step down in Hikma AG royalty rate from 2025 to 2026.

Mitigation:Xywav's unique safety benefits and IH indication; expectation that generics will take time to build volume; strong payer contracts; physician commitment to low-sodium option.

Potential Entry of New Wake-Promoting Agents H2 2026

Could see entry of at least one new wake-promoting agent in the market.

Mitigation:Xywav's ability to offer nighttime benefits that daytime waking agents cannot; continued focus on Xywav's differentiation.

What to watch in Q1 FY26

Zanidatamab sBLA Submission Completion

Q1 FY26
Current Expected in Q1 2026
Target Submission completed

Why it matters

This is a critical step towards potential regulatory approval and launch of zanidatamab in first-line metastatic GEA, a key growth driver.

On the regulatory front, we expect to complete the submission for our supplemental biologics license application for zanidatamab under real-time oncology review in the first quarter of this year.

Q&A highlights

Clarification on Xywav's flat to mid-single-digit growth guidance for 2026, specifically regarding the impact of generic high sodium oxybate products in H1 vs. H2 and potential payer concessions.

Management confirmed that Xywav enters 2026 well-positioned with strong momentum and payer contracts. They expect minimal impact from generics in H1 2026, but anticipate increased competitive dynamics in H2 due to generics building volume and potential entry of new wake-promoting agents. Xywav's differentiation as the only low-sodium oxybate and FDA-approved IH treatment is expected to drive continued growth, particularly from the IH segment.

“We also now have better line of sight into the timing of entry for generic high sodium oxybate products where it appears that now we've got two as we speak, that are in the process of having their launch that could have occurred as early as December 31 of last year, but is occurring now.”

Detailed narrative

Strategic Focus on Rare Disease

Jazz Pharmaceuticals is sharpening its strategic focus on rare disease, leveraging its established capabilities and commitment to delivering life-changing medicines. This strategy aims to strengthen current franchises and expand into new rare disease areas, supported by multiple attractive dynamics in the space.

The company plans to announce future pipeline advancements and new business development transactions aligned with this focus, building on a proven track record in corporate development.

Strong Commercial Performance Across Key Products

The company reported strong commercial execution across its diversified portfolio. Xywav delivered over $2 billion in total revenue in 2025, with 12% growth to $1.7 billion, driven by its low-sodium profile and IH indication. Epidiolex achieved blockbuster status with $1.1 billion in revenue, up 9% year-over-year, with growth opportunities identified in the adult patient population and improved persistency through the Navigator program.

Modeyso, launched in August 2025, generated $48 million in revenue, reflecting significant unmet need and strong early uptake in academic centers.

Zanidatamab: A Key Growth Driver in Oncology

Zanidatamab (Ziihera) is positioned as a key pillar of future growth, with practice-changing Phase III Horizon GEA results demonstrating a clinically meaningful and statistically significant improvement in OS. The FDA granted Breakthrough Designation for zanidatamab in GEA, with an sBLA submission expected in Q1 2026 and potential launch in H2 2026.

A robust development program is underway, including the EmpowHER trial in metastatic breast cancer, with enrollment expected to complete in H1 2027 and top-line data in late 2027 or early 2028.

Pipeline Advancements and Strategic Adjustments

Jazz is advancing its R&D pipeline with several promising opportunities. JZP047, a novel chemical entity developed in-house, initiated a Phase I study for absence epilepsy. A Phase Ib trial of Epidiolex in focal onset seizures was also initiated. The company made a strategic decision to stop the development of JZP441 and end its partnership with Sumitomo, but remains committed to investigating backup orexin programs.

The Modeyso ACTION trial is expected to have an interim overall survival readout in late 2026 or early 2027.

Financial Strength and Capital Allocation

Jazz reported a strong financial position, generating $1.4 billion of cash from operations in 2025 and ending the year with $2.4 billion in cash and investments. The company has substantially deleveraged, with net debt/EBITDA at approximately 1.5x. This robust financial flexibility supports investments in commercial and R&D programs, as well as corporate development opportunities.

The company expects to announce one or more deals in 2026, aligning with its rare disease focus.

Evolving Sleep Market Dynamics

The rare sleep franchise, while delivering strong performance in 2025, faces an evolving competitive landscape in 2026. The introduction of two generic high sodium oxybate products and a modest step down in Hikma AG royalty rates are expected to lead to a modest decrease in total Rare Sleep revenue.

However, Xywav is expected to maintain its position with flat to mid-single-digit growth, supported by its differentiated low-sodium profile and strong payer contracts, despite potential entry of new wake-promoting agents in H2 2026.
