Generated GAAP / non-GAAP1 adjusted earnings per share (EPS) of $2.78 / $5.71 with $824 million in cash from operations in the first half of 2026.
U.S. Food and Drug Administration (FDA) granted Priority Review and set Prescription Drug User Fee Act (PDUFA) target action date of August 25, 2026 for supplemental Biologics License Application (sBLA) for zanidatamab containing combinations in first-line (1L) gastroesophageal adenocarcinoma (GEA).
Results from Phase 3 HERIZON-GEA-01 published in The New England Journal of Medicine; additional subgroup analyses presented in an oral presentation at the 2026 ASCO Annual Meeting showing improved clinical outcomes with zanidatamab-containing combinations regardless of PD-L1 expression, including in PD-L1-negative patients.

Following strong 1H26 commercial execution, the company raised its 2026 revenue guidance range to $4.60 - $4.75 billion, reflecting anticipated double-digit YoY revenue growth from both Xywav and the combined epilepsy and oncology franchises.
Business Updates
Xywav (calcium, magnesium, potassium, and sodium oxybates) oral solution:
Xywav net product sales increased 13% YoY to $471 million in 2Q26.
Robust new patient growth, with approximately 525 net patient adds in 2Q26. There were approximately 17,125 active patients exiting the quarter, comprised of approximately 11,275 narcolepsy patients and approximately 5,850 idiopathic hypersomnia (IH) patients.
Continued physician and patient demand for the differentiated benefits of low-sodium Xywav.
Epidiolex/
Epidyolex (cannabidiol):
Epidiolex/Epidyolex net product sales increased 16% YoY to $292 million in 2Q26, driven by continued strong demand.
Expanded Epidiolex development program to reach more patients with the following clinical trials: Phase 3 trial in developmental and epileptic encephalopathy (DEE), Phase 2/3 trial in juvenile myoclonic epilepsy (JME) and Phase 3b/4 trial in adult Lennox-Gastaut syndrome (LGS).
Submitted New Drug Application (NDA) for cannabidiol capsule formulation to broaden utilization of cannabidiol in currently approved indications and increase flexibility for patients.
Ziihera (zanidatamab-hrii):
Ziihera net product sales in biliary tract cancer (BTC) were $15 million in 2Q26.
Prepared to launch zanidatamab in HER2+ 1L GEA (PDUFA date of August 25, 2026).

Modeyso™ (dordaviprone):
Modeyso net product sales were $48 million in 2Q26 with more than 600 patients having received Modeyso from product launch in August 2025 through the end of the second quarter of 2026.
Anticipate the OS interim analysis for the event-driven Phase 3 ACTION trial in 1H27, based on current pace of event accrual.
Zepzelca® (lurbinectedin):
Zepzelca net product sales increased 42% YoY to $106 million in 2Q26, driven by continued uptake of the Zepzelca and atezolizumab combination in the 1L maintenance ES-SCLC setting, partially offset by a decline in second-line use.
Based on the results from the LAGOON trial of Zepzelca in second-line metastatic SCLC, and in alignment with FDA, in 3Q26, we will submit for FDA's review and subsequent action a labeling supplement to remove the second-line indication. The first-line maintenance indication will not be affected.

Financial Highlights
GAAP and non-GAAP adjusted net income in 2Q26 includes acquired in-process research and development (IPR&D) expense of $77.0 million, relating to upfront payments made in connection with our collaboration and license agreement with AbCellera and asset purchase agreement to acquire remaining rights for JZP898 from Werewolf Therapeutics, Inc. (Werewolf). This impacted our GAAP and non-GAAP adjusted results by $65.4 million (net of tax of $11.6 million) or $0.94 per share.
GAAP and non-GAAP adjusted net loss in 2Q25 includes acquired IPR&D expense of $905.4 million representing the value allocated to Modeyso in the Chimerix Acquisition, which impacted our results by $14.78 per share and $14.75 per share on a GAAP and non-GAAP adjusted basis, respectively.
Reconciliations of applicable GAAP reported to non-GAAP adjusted information are included at the end of this press release.
Total Revenues
Total revenues increased 16% in 2Q26 YoY primarily due to higher Xywav, Epidiolex/Epidyolex and Zepzelca net product sales and the inclusion of Modeyso net product sales, following FDA approval in August 2025.
Operating Expenses and Income Tax Expense (Benefit)
Changes in operating expenses and income tax expense (benefit) in 2Q26 over the prior year period are primarily due to the following:
Cost of product sales, on a GAAP and non-GAAP adjusted basis, increased in 2Q26, primarily due to higher royalty expenses, driven by higher revenues of Modeyso and Zepzelca, offset on a GAAP basis, by lower acquisition accounting inventory fair value step up expense.
Selling, general and administrative (SG&A) expenses, on a GAAP and non-GAAP adjusted basis, increased in 2Q26, primarily due to higher marketing investment and compensation-related expenses in support of our commercial portfolio.
Research and development (R&D) expenses, on a GAAP and non-GAAP adjusted basis, increased in 2Q26, driven by higher clinical studies costs, primarily related to zanidatamab.
Acquired IPR&D, on a GAAP and non-GAAP adjusted basis, in 2Q26 comprised the upfront payments to AbCellera and Werewolf.
Income tax expense, on a GAAP and non-GAAP adjusted basis, in 2Q26 reflects changes in the geographic mix of income and expenses compared to 2Q25.
Cash Flow and Balance Sheet
As of June 30, 2026, cash, cash equivalents and investments were $2.2 billion, and the outstanding principal balance of the company's long-term debt was $4.4 billion. In addition, the company had undrawn borrowing capacity under a revolving credit facility of $885 million.

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 (loss) (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 (loss) (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 (loss) (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 (loss), 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 (loss) 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. 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.
