We also advanced multiple trials across our zanidatamab development program and expect top-line data readout from the HERIZON-GEA-01 trial in 1L GEA in the second half of 2025." Key Highlights Top-line PFS data from zanidatamab in Phase 3 1L GEA expected in 2H25. Submitted sNDA for Zepzelca in combination with atezolizumab (Tecentriq®) as maintenance therapy in 1L ES-SCLC based on the potentially practice-changing results from the Phase 3 IMforte trial. Data from trial to be presented at the 2025 ASCO Annual Meeting in June 2025 . Acquisition of Chimerix added dordaviprone to late-stage pipeline, representing near-term commercial opportunity; PDUFA target data of August 18, 2025 .

Total revenue guidance is underpinned by expected continued growth of Jazz's diversified commercial portfolio. Business Updates Commercial Updates Xywav (calcium, magnesium, potassium, and sodium oxybates) oral solution: Xywav net product sales increased 9% to $344.8 million in 1Q25 compared to 1Q24. Meaningful Xywav net patient adds in 1Q25 (approximately 450 patients) with approximately 14,600 active Xywav patients exiting 1Q25, comprised of: Approximately 10,375 narcolepsy patients. Approximately 4,225 idiopathic hypersomnia (IH) patients, with 325 net patient adds. Two presentations at the American Academy of Neurology Annual Meeting provided updated results from the open-label, single-arm, Phase 4 DUET trial of adults with narcolepsy or IH. The results demonstrated statistically significant improvements from baseline to end of treatment in Epworth Sleepiness Scale (ESS) scores, reduced sleep stage shifts, increased deep sleep and reduced number of awakenings among adults with narcolepsy treated with Xywav. In adults with IH, Xywav treatment showed improvements in ESS and IH Severity Scale scores. Xywav is the only low-sodium oxybate, the #1 branded treatment for narcolepsy1 and the only U.S. Food and Drug Administration (FDA)-approved therapy to treat IH. Approximately 10,375 narcolepsy patients. Approximately 4,225 idiopathic hypersomnia (IH) patients, with 325 net patient adds. Xyrem (sodium oxybate) oral solution and high-sodium oxybate authorized generic (AG) royalties: Xyrem net product sales decreased 42% to $37.2 million in 1Q25 compared to 1Q24. Royalties from high-sodium oxybate AGs were $48 .9 million in 1Q25. Epidiolex/Epidyolex® (cannabidiol): Epidiolex/Epidyolex net product sales increased 10% to $217.7 million in 1Q25 compared to 1Q24. Outside of the U.S., Epidyolex is approved in more than 35 countries. Remain confident in achieving blockbuster status for Epidiolex/Epidyolex in 2025. Rylaze®/Enrylaze® (asparaginase erwinia chrysanthemi (recombinant)-rywn): Rylaze/Enrylaze net product sales decreased 8% to $94.2 million in 1Q25 compared to 1Q24. This decrease was driven by headwinds from an update to Children's Oncology Group (COG) pediatric treatment protocols for acute lymphoblastic leukemia made in mid-2024 that impacted timing of asparaginase administration. The impact to Rylaze net product sales due to COG protocol updates is expected to normalize during 2Q25. Zepzelca (lurbinectedin): Zepzelca net product sales decreased 16% to $63.0 million in 1Q25 compared to 1Q24. This decrease was driven by increased competition in second-line (2L) small cell lung cancer (SCLC) and treatment protocol updates delaying progression in first-line (1L) limited-stage SCLC patients to the 2L setting. The Company submitted a supplemental New Drug Application (sNDA) for Zepzelca's use in combination with atezolizumab as maintenance therapy in 1L extensive-stage (ES) SCLC for patients who have not progressed after induction chemotherapy. Potentially practice-changing data from the Phase 3 IMforte trial, which showed a statistically significant and clinically meaningful benefit in both progression-free survival (PFS) and overall survival for the Zepzelca and atezolizumab combination for ES-SCLC patients receiving this treatment in the first-line maintenance setting, was accepted for an oral presentation at the upcoming American Society of Clinical Oncology (ASCO) Annual Meeting. This is the first presentation of data from the IMforte trial. Ziihera (zanidatamab-hrii): Ziihera net product sales were $2.0 million in 1Q25 following product launch in December 2024 . On April 25, 2025 , the Company announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency has adopted a positive opinion recommending the conditional marketing authorization of zanidatamab in 2L BTC (biliary tract cancer). The CHMP recommendation is being reviewed by the European Commission . __________________________ 1 Based on 1Q25 Xywav net product sales. Corporate Development Chimerix Acquisition: The Company completed its acquisition of Chimerix in April 2025 , adding dordaviprone to its late-stage pipeline. Dordaviprone is a novel first-in-class small molecule treatment in development for H3 K27M-mutant diffuse glioma, a rare, high-grade brain tumor that most commonly affects children and young adults. Key Pipeline Highlights Zanidatamab: The pivotal HERIZON-GEA-01 trial, evaluating zanidatamab in 1L gastroesophageal adenocarcinoma (GEA), is expected to read out in 2H25 based on the most recent assessment of progression events. Recruitment for the trial has been completed. New data from an ongoing Phase 2 trial of zanidatamab in combination with chemotherapy for the first-line treatment of HER2-positive metastatic GEA, including more mature overall survival data, was accepted for a rapid oral presentation at the 2025 ASCO Annual Meeting. The Phase 3 EmpowHER-BC-303 trial to evaluate zanidatamab plus chemotherapy or trastuzumab plus chemotherapy in patients with HER2-positive breast cancer whose disease has progressed on previous T-DXd treatment continues to enroll patients. The Phase 2 pan-tumor trial to evaluate HER2-positive solid tumors continues to enroll patients. Dordaviprone: A New Drug Application for accelerated approval of dordaviprone in recurrent H3 K27M-mutant diffuse glioma was accepted and granted Priority Review by FDA. FDA has set a target Prescription Drug User Fee Act (PDUFA) action date of August 18, 2025 . The ongoing Phase 3 ACTION trial is evaluating dordaviprone in newly diagnosed, non-recurrent H3 K27M-mutant diffuse glioma patients following radiation treatment, potentially extending its use into the first-line setting. Data on the efficacy and safety of dordaviprone from prospective clinical trials of adult and pediatric recurrent H3 K27M-mutant diffuse glioma patients was accepted for an oral presentation at the 2025 ASCO Annual Meeting.

Commencing with the first quarter of 2025, we are no longer including an adjustment for non-cash interest expense in the Company's non-GAAP adjusted financial measures and for the purposes of comparability, non-GAAP adjusted financial measures for the first quarter of 2024 have been updated to reflect this change. See "Non-GAAP Financial Measures" below. GAAP net loss for 1Q25 was $(92.5) million , or $(1.52) per diluted share, compared to $(14.6) million , or $(0.23) per diluted share, for 1Q24. Non-GAAP adjusted net income for 1Q25 was $105 .2 million, or $1.68 per diluted share, compared to $178 .4 million, or $2.63 per diluted share, for 1Q24. The GAAP net loss and non-GAAP adjusted net income for 1Q25 included an expense of $172.0 million related to certain Xyrem antitrust litigation settlements, which impacted our GAAP and non-GAAP results by $146.3 million (net of tax of $25.7 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 neuroscience revenue, including high-sodium oxybate AG royalty revenue, was $654 .1 million in 1Q25, an increase of 4% compared to $630.9 million in 1Q24. The increase in 1Q25 was due to higher Xywav and Epidiolex/Epidyolex net product sales, partially offset by decreased Xyrem net product sales. Oncology net product sales were $229 .4 million in 1Q25, a decrease of 11% compared to $257 .5 million in 1Q24. The decrease in 1Q25 was primarily due to lower net product sales of Zepzelca, Rylaze/Enrylaze and Defitelio/defibrotide. In 1Q25, Rylaze net product sales were negatively impacted due to an update to the COG pediatric treatment protocols for ALL, which impacts the timing of asparaginase administration. Operating Expenses and Effective Tax Rate Three Months Ended March 31 , (In thousands, except percentages) 2025 2024 GAAP: Cost of product sales $ 104,620 $ 95,487 Gross margin 87.5 % 88.7 % Selling, general and administrative $ 514,013 $ 351,712 % of total revenues 57.2 % 39.0 % Research and development $ 180,652 $ 222,847 % of total revenues 20.1 % 24.7 % Acquired in-process research and development $ — $ 10,000 Income tax (benefit) expense1 $ (17,812) $ 11,669 Effective tax rate 1 16.2 % (728.4) % _________________________ 1. The GAAP income tax benefit in 1Q25 related primarily to the tax impact of certain Xyrem antitrust litigation settlements. The GAAP income tax expense in 1Q24 related primarily to tax shortfalls from share-based compensation. Three Months Ended March 31 , (In thousands, except percentages) 2025 2024 Non-GAAP adjusted: Cost of product sales $ 69,691 $ 64,148 Gross margin 91.7 % 92.4 % Selling, general and administrative $ 472,339 $ 311,499 % of total revenues 52.6 % 34.5 % Research and development $ 159,722 $ 204,015 % of total revenues 17.8 % 22.6 % Acquired in-process research and development $ — $ 10,000 Income tax expense1 $ 36,394 $ 64,735 Effective tax rate1 25.6 % 26.5 % _________________________ 1. The non-GAAP income tax expense decreased in the three months ended March 31, 2025 , compared to the same period in 2024, primarily due to the tax impact of certain Xyrem antitrust settlements in 1Q25. Changes in operating expenses in 1Q25 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 1Q25 compared to the same period in 2024, primarily due to changes in product mix and higher inventory provisions. SG&A expenses, on a GAAP and non-GAAP adjusted basis, increased in 1Q25 compared to the same period in 2024, primarily due to certain Xyrem antitrust litigation settlements of $172.0 million incurred in 1Q25. Research and development (R&D) expenses, on a GAAP and non-GAAP adjusted basis, decreased in 1Q25 primarily due to lower clinical study costs primarily related to zanidatamab, as a result of timing of clinical trial activities, and JZP385 (essential tremor) and JZP150 (post-traumatic stress disorder) following discontinuation of these programs. Acquired in-process research and development (IPR&D) in 1Q24, on a GAAP and non-GAAP adjusted basis, related to an upfront payment made in connection with our asset purchase agreement with Redx Pharma plc . Cash Flow and Balance Sheet As of March 31, 2025 , cash, cash equivalents and investments were $2 .6 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 three months ended March 31, 2025 , the Company generated $429 .8 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 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 first quarter of 2024 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.

Potentially dilutive ordinary shares from Jazz's employee equity incentive and purchase plans were excluded from the calculation of diluted loss per ordinary share, or LPS, on a GAAP basis, for the three months ended March 31, 2025 and March 31, 2024 because their effect would have been anti-dilutive. Diluted earnings per ordinary share, or EPS, was calculated using the "if-converted" method in relation to the 2.000% exchangeable senior notes due 2026, or the 2026 Notes. In July 2024 , we made the irrevocable election to net share settle the 2026 Notes. As a result, the assumed issuance of ordinary shares upon exchange of the 2026 Notes has only been included in the calculation of diluted EPS, on a non-GAAP adjusted basis, in the three months ended March 31, 2024 . The potential issue of ordinary shares upon exchange of the 2026 Notes was anti-dilutive and had no impact on GAAP reported LPS for the three months ended March 31, 2024 .

First Global Phase 3 Trial Showing Substantial Survival Advantage Over Chemotherapy, for Patients With Progression On or After Platinum-Based Chemotherapy THOUSAND OAKS, CA, USA I April 11, 2025 I Amgen (NASDAQ: AMGN ) today announced that the global Phase 3 DeLLphi-304 clinical trial evaluating IMDELLTRA ® (tarlatamab-dlle) as a treatment for patients with small cell lung cancer (SCLC) who progressed on or after a single line of platinum-based chemotherapy met its primary endpoint at a planned interim analysis. IMDELLTRA demonstrated statistically significant and clinically meaningful improvement in overall survival (OS) compared to local standard-of-care (SOC) chemotherapy. “Small cell lung cancer is one of the most aggressive malignancies, with a high unmet need for more effective therapies. 1 The topline results from DeLLphi-304 demonstrate overwhelming clinical benefit for people living with this devastating disease and affirm IMDELLTRA as standard of care,” said Jay Bradner, M.D., executive vice president, Research and Development, at Amgen. “We look forward to sharing these results with the scientific community and health authorities as we continue our efforts to bring IMDELLTRA to patients worldwide.” The safety profile for IMDELLTRA was consistent with its known profile. Detailed data from DeLLphi-304 will be presented at an upcoming medical congress. DeLLphi-304 is a global Phase 3 randomized controlled open-label clinical trial evaluating the efficacy and safety of IMDELLTRA as a treatment for patients with SCLC who progressed on or after a single line of platinum-based chemotherapy. 2 Patients were randomized to receive either IMDELLTRA or local SOC chemotherapy (topotecan in all countries except Japan; lurbinectedin in the U.S., Canada, Australia, Singapore, Korea; and amrubicin in Japan). 2,3 The primary outcome measure of the trial is OS. 2 About IMDELLTRA ® (tarlatamab-dlle) IMDELLTRA is a first-in-class immunotherapy engineered by Amgen researchers that binds to both DLL3 on tumor cells and CD3 on T cells, activating T cells to kill DLL3-expressing SCLC cells. This results in the formation of a cytolytic synapse with lysis of the cancer cell. 4,5 DLL3 is a protein that is expressed on the surface of SCLC cells in ~85-96% of patients with SCLC, but is minimally expressed on healthy cells, making it an exciting target. 6,7 IMDELLTRA ® (tarlatamab-dlle) U.S. Indication IMDELLTRA ® (tarlatamab-dlle) is indicated for the treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC) with disease progression on or after platinum-based chemotherapy. This indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s). About Small Cell Lung Cancer (SCLC) SCLC is one of the most aggressive and devastating solid tumor malignancies, with a 5-10% five-year relative survival rate across all stages combined. 1 SCLC comprises about 15% of the more than 2.4 million patients diagnosed with lung cancer worldwide each year. 8-10 Despite initial high response rates to first-line platinum-based chemotherapy, most patients quickly relapse within months and require subsequent treatment options. 9 About Tarlatamab Clinical Trials Amgen’s robust tarlatamab development program includes the DeLLphi clinical trials, which evaluate tarlatamab as both a monotherapy and in combination regimens in earlier lines of SCLC. Tarlatamab is being investigated in multiple studies including DeLLphi-303, a Phase 1b study investigating tarlatamab in combination with standard of care therapies in first-line ES-SCLC; DeLLphi-304, a randomized Phase 3 trial comparing tarlatamab monotherapy with standard of care chemotherapy in second-line treatment of SCLC; DeLLphi-305, a randomized Phase 3 trial comparing tarlatamab in combination with durvalumab versus durvalumab alone as first-line maintenance treatment in ES-SCLC; DeLLphi-306, a randomized placebo-controlled Phase 3 trial of tarlatamab following concurrent chemoradiotherapy in limited-stage SCLC; DeLLphi-308, a Phase 1b study evaluating subcutaneous tarlatamab in second line or later ES-SCLC; and DeLLphi-309, a Phase 2 study evaluating alternative intravenous dosing regimens with tarlatamab in second-line ES-SCLC. 11 For more information, please visit www.tarlatamabclinicaltrials.com .
