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 7% in 3Q25 compared to the same period in 2024.
Total neuroscience revenue, including high-sodium oxybate AG royalty revenue, increased 9% to $827.4 million in 3Q25, compared to 3Q24. The increase in 3Q25 was due to higher Epidiolex/Epidyolex and Xywav net product sales, partially offset by decreased Xyrem net product sales.
Oncology net product sales increased 1% to $287.8 million in 3Q25, compared to 3Q24, due to the inclusion of Modeyso and Ziihera net product sales, offset by lower net product sales of Defitelio/defibrotide and Zepzelca.
Operating Expenses and Income Tax (Benefit) Expense
_________________________
_________________________
Changes in operating expenses and income tax (benefit) expense in 3Q25 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 3Q25 compared to 3Q24, primarily due to higher inventory provisions and changes in product mix. Cost of product sales, on a GAAP basis, included higher acquisition accounting inventory fair value step-up expense in 3Q25 as compared to 3Q24.
Selling, general and administrative (SG&A) expenses, on a GAAP and non-GAAP adjusted basis, increased in 3Q25 compared to 3Q24, primarily due to the Avadel litigation settlement of $90.0 million and a Xyrem antitrust litigation settlement of $61.5 million, and, to a lesser extent, higher compensation-related expenses driven by higher headcount along with increased investment in sales and marketing in support of our commercial portfolio. SG&A expenses, on a GAAP basis, also included increased share-based compensation expense.
Research and development (R&D) expenses, on a GAAP and non-GAAP adjusted basis, decreased in 3Q25 compared to 3Q24, 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 this trial in the first half of 2025, partially offset by the addition of costs relating to Modeyso following the Chimerix acquisition. R&D expenses, on a GAAP basis, included integration expenses related to the Chimerix acquisition of $6.5 million.
Acquired in-process research and development (IPR&D) in 3Q25, on a GAAP and non-GAAP adjusted basis, represents the upfront payment made in connection with our global license agreement with Saniona.
Income tax benefit in 3Q25, on a GAAP and non-GAAP adjusted basis, included a benefit of $205.9 million on recognition of certain U.S. federal and state deferred tax assets acquired through the Chimerix acquisition.
Cash Flow and Balance Sheet
As of September 30, 2025, cash, cash equivalents and investments were $2.0 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 $885.0 million. For the nine months ended September 30, 2025, the Company generated $993.3 million 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.
