DUBLIN, Feb. 24, 2026 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) today announced financial results for the full year and fourth quarter of 2025 and provided financial guidance for 2026.
"2025 was an exceptional year for Jazz, representing our 21st consecutive year of top-line growth and underscoring our commitment to operational excellence as we deliver meaningful innovation for patients," said Renee Gala, president and chief executive officer of Jazz Pharmaceuticals. "In the fourth quarter, our disciplined execution resulted in $1.2 billion in revenue, reflecting 10% year-over-year growth and our highest revenue quarter ever. This performance provides us with strong momentum into 2026, as we prepare for the potential launch of zanidatamab in GEA, sustain launch execution for Modeyso and Zepzelca®, and reinforce the differentiated profiles of Epidiolex and Xywav as the leading branded treatments for epilepsy and narcolepsy, respectively. In parallel, we continue to advance our pipeline and pursue a corporate development strategy aligned with our rare disease focus that supports durable growth and long-term value creation for patients and shareholders."
"Jazz had a transformative year across our R&D pipeline, led by the HERIZON-GEA-01 data, which we believe firmly positions zanidatamab as the HER2-targeted agent of choice, with the potential to reshape first-line treatment for HER2+ metastatic GEA patients," said Rob Iannone, M.D., M.S.C.E., executive vice president, global head of research and development, and chief medical officer of Jazz Pharmaceuticals. "We expect to build on this progress in 2026, as these results not only highlight zanidatamab's potential to help patients with GEA, but also de-risk our clinical trials in additional indications, including HER2+ metastatic breast cancer."
Key 2025 Highlights
Total revenues in 2025 grew to $4.3 billion (+5% year-over-year (YoY)), generating $1.4 billion in cash from operations.

Financial Highlights
Reconciliations of applicable GAAP reported to non-GAAP adjusted information are included at the end of this press release.
Total Revenues
Total revenues increased 5% in 2025 and 10% in 4Q25 compared to the same periods in 2024.
Total neuroscience revenue, including high-sodium oxybate AG royalty revenue, was $3.1 billion in 2025, an increase of 6% compared to $2.9 billion in 2024, and $848 million in 4Q25, an increase of 8% compared to $786 million in 4Q24. The increase in both periods was primarily due to higher Xywav and Epidiolex/Epidyolex net product sales, partially offset by decreased Xyrem net product sales.
Oncology net product sales were $1.1 billion in 2025, an increase of 2% compared to 2024, and $337 million in 4Q25, an increase of 16% compared to $292 million in 4Q24, primarily due to the inclusion of Modeyso and Ziihera net product sales in both periods. The increase in 4Q25 also included higher Zepzelca net product sales, partially offset by decreased Vyxeos® net product sales.
Operating Expenses and Income Tax (Benefit) Expense
Changes in operating expenses and income tax (benefit) expense in 2025 and 4Q25 over the prior year periods are primarily due to the following:
Cost of product sales, on a GAAP and non-GAAP adjusted basis, increased in 2025 compared to 2024, primarily due to changes in product mix. Cost of product sales, on a GAAP basis, in 2025 included higher acquisition accounting inventory fair value step up expense compared to 2024. Cost of product sales, on a GAAP and non-GAAP adjusted basis, increased in 4Q25 compared to 4Q24, primarily due to changes in product mix, partially offset by lower inventory provisions.
Selling, general and administrative (SG&A) expenses, on a GAAP and non-GAAP adjusted basis, increased in 2025 compared to 2024, primarily due to Xyrem antitrust litigation settlements of $234 million, the Avadel litigation settlement of $90 million and higher compensation-related expenses. SG&A expenses, on a GAAP and non-GAAP adjusted basis, increased in 4Q25 compared to 4Q24, primarily due to higher compensation-related expenses.
Research and development (R&D) expenses, on a GAAP and non-GAAP adjusted basis, decreased in 2025 and 4Q25, compared to the same periods in 2024, primarily due to lower clinical study costs primarily related to zanidatamab as a result of timing of clinical trial activities, JZP385 (essential tremor) following discontinuation of this program, and JZP258 (XYLO/DUET) due to the completion of these trials in the first half of 2025, partially offset by the addition of costs relating to Modeyso and increased personnel costs following the acquisition of Chimerix.
Acquired in-process research and development (IPR&D) in 2025, on a GAAP and non-GAAP adjusted basis, represents the value allocated to Modeyso in the Chimerix Acquisition of $905 million and the upfront payment made in connection with our global license agreement with Saniona of $43 million.
Income tax benefit in 2025, on a GAAP and non-GAAP adjusted basis, included a benefit of $213 million on recognition of certain U.S. federal and state deferred tax assets acquired through the Chimerix acquisition. Income tax benefit, on a GAAP and non-GAAP adjusted basis, in 4Q24 was primarily due to patent box benefits recognized.
Cash Flow and Balance Sheet
As of December 31, 2025, cash, cash equivalents and investments were $2.4 billion, and the outstanding principal balance of the Company's long-term debt was $5.4 billion. In addition, the Company had undrawn borrowing capacity under a revolving credit facility of $885 million. For the year ended December 31, 2025, the Company generated $1.4 billion of cash from operations reflecting strong business performance and continued financial discipline.

Non-GAAP Financial Measures
To supplement Jazz Pharmaceuticals' financial results and guidance presented in accordance with U.S. generally accepted accounting principles (GAAP), the Company uses certain non-GAAP (also referred to as adjusted or non-GAAP adjusted) financial measures in this press release and the accompanying tables. In particular, the Company presents non-GAAP adjusted net income (and the related per share measure) and its line-item components, as well as certain non-GAAP adjusted financial measures derived therefrom, including non-GAAP adjusted gross margin percentage and non-GAAP adjusted effective tax rate. Non-GAAP adjusted net income (and the related per share measure) and its line-item components exclude from GAAP reported net income (loss) (and the related per share measure) and its line-item components certain items, as detailed in the reconciliation tables that follow, and in the case of non-GAAP adjusted net income (and the related per share measure), adjust for the income tax effect of the non-GAAP adjustments. In this regard, the components of non-GAAP adjusted net income, including non-GAAP adjusted cost of product sales, SG&A expenses and R&D expenses, are income statement line items prepared on the same basis as, and therefore components of, the overall non-GAAP adjusted net income measure.
The Company believes that each of these non-GAAP financial measures provides useful supplementary information to, and facilitates additional analysis by, investors and analysts and that each of these non-GAAP financial measures, when considered together with the Company's financial information prepared in accordance with GAAP, can enhance investors' and analysts' ability to meaningfully compare the Company's results from period to period, to its forward-looking guidance, and to identify operating trends in the Company's business. In addition, these non-GAAP financial measures are regularly used by investors and analysts to model and track the Company's financial performance. Jazz Pharmaceuticals' management also regularly uses these non-GAAP financial measures internally to understand, manage and evaluate the Company's business and to make operating decisions, and compensation of executives is based in part on certain of these non-GAAP financial measures. Because these non-GAAP financial measures are important internal measurements for Jazz Pharmaceuticals' management, the Company also believes that these non-GAAP financial measures are useful to investors and analysts since these measures allow for greater transparency with respect to key financial metrics the Company uses in assessing its own operating performance and making operating decisions. These non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP measures; should be read in conjunction with the Company's consolidated financial statements prepared in accordance with GAAP; have no standardized meaning prescribed by GAAP; and are not prepared under any comprehensive set of accounting rules or principles in the reconciliation tables that follow. 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 has ceased, and may in the future cease, to exclude items that it has historically excluded for purposes of its non-GAAP financial measures. In this regard, commencing with the first quarter of 2025, the Company is no longer including an adjustment for non-cash interest expense in the Company's non-GAAP adjusted financial measures. For purposes of comparability, non-GAAP adjusted financial measures for the 2024 periods have been updated to reflect this change. Likewise, the Company may determine to modify the nature of its adjustments to arrive at its non-GAAP financial measures. Because of the non-standardized definitions of non-GAAP financial measures, the non-GAAP financial measures as used by Jazz Pharmaceuticals in this press release and the accompanying tables have limits in their usefulness to investors and may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by other companies.
