Recent Key Highlights Highest ever total quarterly revenues of $1.2 billion with 16% year-over-year (YoY) growth. 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. FDA granted Breakthrough Therapy designation (BTD) for zanidatamab in adults with previously treated locally advanced, unresectable, or metastatic HER2-positive colorectal cancer (CRC). 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). Top-line results from the second interim overall survival (OS) analysis for the HERIZON-GEA-01 trial doublet regimen are expected in 3Q26. 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. Corporate Development: Announced a preclinical research collaboration with AbCellera Biologics Inc. (AbCellera), to develop next-generation T-cell engaging multispecific antibodies for multiple gastrointestinal (GI) cancers and other solid tumors. The company continues to actively evaluate additional value-enhancing corporate development. 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. In June 2026, we repaid the $1.0 billion aggregate principal amount of the 2.00% exchangeable senior notes due 2026. For the six months ended June 30, 2026, the company generated $824 million of cash from operations reflecting strong business performance and continued financial discipline. 2026 Financial Guidance Jazz Pharmaceuticals has updated its full-year 2026 financial guidance as shown in the table below.

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.

"Our first-quarter results reflect disciplined execution across the business, delivering 19% year-over-year growth alongside key pipeline advancements and positioning the company for an outstanding 2026," said Renee Gala, president and chief executive officer of Jazz Pharmaceuticals. "Demand for Xywav remained strong, our rare oncology launches with Modeyso™ and Zepzelca® in 1LM ES-SCLC gained significant momentum, and Epidiolex continued to provide consistent growth. Looking ahead, we are excited about the potential launch of zanidatamab in 1L GEA later this year, as we progress our pipeline and business development efforts to bring more life-changing therapies to patients and fuel durable long-term growth." Key First Quarter 2026 Highlights Total revenues in 1Q26 grew to $1.1 billion (+19% year-over-year (YoY)) Generated GAAP / non-GAAP1 adjusted earnings per share (EPS) of $4.43 / $6.34 with $408 million in cash from operations. Practice-changing Phase 3 HERIZON-GEA-01 results, presented as a late-breaker at ASCO GI, support zanidatamab as the HER2-targeted agent of choice in HER2+ 1L advanced gastroesophageal adenocarcinoma (GEA); additional benefit from tislelizumab irrespective of PD-L1 status. Supplemental Biologics License Application (sBLA) accepted by FDA under Real-Time Oncology Review (RTOR) program with potential approval and launch in 1L HER2+ GEA on or before PDUFA date. Business Updates Xywav (calcium, magnesium, potassium, and sodium oxybates) oral solution: Xywav net product sales increased 18% to $408 million in 1Q26, compared to 1Q25. Continued physician and patient demand for the differentiated benefits of low-sodium Xywav. Strong new patient growth, with approximately 425 net patient adds in 1Q26. There were approximately 16,600 active patients exiting the quarter, comprised of approximately 11,075 narcolepsy patients and approximately 5,525 idiopathic hypersomnia (IH) patients. Epidiolex/ Epidyolex (cannabidiol): Epidiolex/Epidyolex net product sales increased 15% YoY to $250 million in 1Q26, driven by continued strong demand. Announced agreement with Nippon Zoki to commercialize Epidyolex in Japan, following completion of ongoing clinical trials and potential regulatory approval. Ziihera ® (zanidatamab-hrii): Ziihera net product sales in biliary tract cancer (BTC) were $13 million in 1Q26. In April 2026, FDA accepted the zanidatamab sBLA in GEA for a Priority Review, with a PDUFA date of August 25, 2026. Submitted HERIZON-GEA-01 data for potential National Comprehensive Cancer Network (NCCN) guideline inclusion. HERIZON-GEA-01 data accepted for publication by a top-tier medical journal. The second interim overall survival (OS) analysis for the HERIZON-GEA-01 trial doublet regimen is expected in mid-2026. Multiple registrational trials of zanidatamab are underway, including in metastatic breast cancer (mBC), supporting a broad development program designed to maximize patient impact and long-term shareholder value. Modeyso (dordaviprone): Modeyso net product sales were $41 million in 1Q26 with ~500 patients having received Modeyso from product launch in August 2025 through the end of the first quarter. The company completed the sale of its Rare Pediatric Disease Priority Review Voucher (PRV) for gross proceeds of $200 million (50% to Jazz). Phase 3 ACTION trial remains on track with top-line readout expected late 2026 / early 2027. Zepzelca (lurbinectedin): Zepzelca net product sales increased 60% YoY to $101 million in 1Q26, driven by continued uptake of the Zepzelca and atezolizumab combination in the 1LM ES-SCLC setting, partially offset by a decline in second line use. The company expects second line use to decline throughout the year. Financial Highlights The GAAP net loss and non-GAAP adjusted net income for 1Q25 included an expense of $172 million related to Xyrem antitrust litigation settlements, which impacted our GAAP and non-GAAP results by $146 million (net of tax of $26 million), or $2.38 per share on a GAAP basis and $2.34 per share on a non-GAAP adjusted basis. Reconciliations of applicable GAAP reported to non-GAAP adjusted information are included at the end of this press release. Total Revenues Total revenues increased 19% YoY primarily due to higher Xywav, Zepzelca and Epidiolex/Epidyolex 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 1Q26 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 1Q26, primarily due to higher royalty expenses, driven by higher revenues, and increased inventory provisions. The cost of product sales, on a GAAP basis, in 1Q26 included higher acquisition accounting inventory fair value step up expense compared to 1Q25. Selling, general and administrative (SG&A) expenses, on a GAAP and non-GAAP adjusted basis, decreased in 1Q26, primarily due to certain Xyrem antitrust litigation settlements of $172 million incurred in 1Q25, partially offset by higher compensation-related expenses in 1Q26 including costs relating to Modeyso. Research and development (R&D) expenses, on a GAAP and non-GAAP adjusted basis, increased in 1Q26, primarily due to the addition of costs relating to Modeyso including personnel costs. Income tax expense in 1Q26, on a GAAP basis, was primarily attributable to the gain recognized on the sale of the PRV, partially offset by excess tax benefits from share-based compensation. Income tax benefit in 1Q25, on a GAAP basis, was primarily attributable to the Xyrem antitrust litigation settlements. Cash Flow and Balance Sheet As of March 31, 2026, cash, cash equivalents and investments were $2.9 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.
