Updated ASCO data for ZL-1310 (DLL3 ADC) reaffirm its best-in-class potential in second-line SCLC, and we are moving swiftly into pivotal development while exploring opportunities in first-line SCLC and other neuroendocrine carcinomas. We were also encouraged by positive data for bemarituzumab in first-line gastric cancer and by emerging preclinical results for our IL-13/IL-31 bispecific antibody in atopic dermatitis, reinforcing both our near-term commercial opportunities and the potential of our global pipeline, respectively. With multiple launches ahead, a robust pipeline, and profitability1 within reach, Zai Lab is executing on its vision to become a leading global biopharma company.” “VYVGART continues to lead our commercial momentum, with record patient utilization driven by longer treatment durations and growing adoption in the maintenance setting,” said Josh Smiley , President and COO of Zai Lab . “The July update to national MG guidelines further strengthens VYVGART’s role in both acute and chronic care, and we expect momentum to accelerate in the second half. We are also preparing for several high-impact launches – including KarXT and bemarituzumab – that, together with pipeline-in-a-product assets like VYVGART and povetacicept, will fuel our next wave of growth. With a 28% year-over-year reduction in operating loss and a 37% improvement on an adjusted basis, we are on track to achieve profitability1 in the fourth quarter. Backed by a strong cash position2, a growing commercial business, and an advancing global pipeline, Zai Lab is well equipped to deliver long-term shareholder value.” 1 Refers to adjusted income (loss) from operations (non-GAAP), calculated as GAAP income (loss) from operations adjusted to exclude certain non-cash expenses, including depreciation, amortization, and share-based compensation. For additional information on this adjusted profitability measure, refer to the “Non-GAAP Measures” section. 2 Cash position includes cash and cash equivalents, current restricted cash, and short-term investments. Second Quarter 2025 Financial Results Product revenue, net was $109.1 million in the second quarter of 2025, compared to $100.1 million for the same period in 2024, representing 9% y-o-y growth, 10% y-o-y growth at constant exchange rate (CER). This increase was primarily driven by increased sales for VYVGART, XACDURO, and NUZYRA, partially offset by softer sales for ZEJULA: VYVGART and VYVGART Hytrulo were $26.5 million in the second quarter of 2025, compared to $18.1 million in the first quarter of 2025. Sales grew 46% quarter over quarter driven by an extension of duration of therapy and increasing market penetration. ZEJULA was $41.0 million in the second quarter of 2025, compared to $45.0 million for the same period in 2024. Sales were softer due to evolving competitive dynamics within the PARPi class. XACDURO, which was launched since the fourth quarter of 2024, was $4.6 million in the second quarter of 2025. NUZYRA was $14.3 million in the second quarter of 2025, compared to $12.3 million for the same period in 2024. This growth was supported by increasing market coverage and penetration. Research and Development (R&D) expenses were $50.6 million in the second quarter of 2025, compared to $61.6 million for the same period in 2024. The decrease reflects reduced personnel and clinical trial costs, driven by ongoing resource prioritization and efficiency efforts. Selling, General and Administrative expenses were $71.0 million in the second quarter of 2025, compared to $79.7 million for the same period in 2024. The decrease was primarily driven by reduced personnel costs because of resource prioritization and efficiency efforts. Loss from operations was $54.9 million in the second quarter of 2025, $34.2 million when adjusted to exclude certain non-cash expenses including depreciation, amortization, and share-based compensation. A reconciliation of loss from operations (GAAP) to adjusted loss from operations (non-GAAP) is included at the end of this release. Net loss was $40.7 million in the second quarter of 2025, or a loss per ordinary share attributable to common stockholders of $0.04 (or loss per American Deposit Share (ADS) of $0.37 ), compared to a net loss of $80.3 million for the same period in 2024, or a loss per ordinary share of $0.08 (or loss per ADS of $0.82 ). These decreases in net loss were primarily due to product revenue growing faster than net operating expenses. Cash and cash equivalents, short-term investments, and current restricted cash totaled $832.3 million as of June 30, 2025 , compared to $857.3 million as of March 31, 2025 . VYVGART and VYVGART Hytrulo were $26.5 million in the second quarter of 2025, compared to $18.1 million in the first quarter of 2025. Sales grew 46% quarter over quarter driven by an extension of duration of therapy and increasing market penetration. ZEJULA was $41.0 million in the second quarter of 2025, compared to $45.0 million for the same period in 2024. Sales were softer due to evolving competitive dynamics within the PARPi class. XACDURO, which was launched since the fourth quarter of 2024, was $4.6 million in the second quarter of 2025. NUZYRA was $14.3 million in the second quarter of 2025, compared to $12.3 million for the same period in 2024. This growth was supported by increasing market coverage and penetration. Recent Pipeline Highlights Below are key product updates since our last earnings release: Oncology Pipeline ZL-1310 (DLL3 ADC): In June 2025 , Zai Lab presented positive data from an ongoing, global Phase 1a/1b clinical trial of ZL-1310 for the treatment of patients with extensive-stage small cell lung cancer (ES-SCLC) at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting. In second-line (2L) SCLC, objective response rate (ORR) was 67% across all dose levels (n=33) and 79% at 1.6 mg/kg dose (n=14). ZL-1310 demonstrated a well-tolerated safety profile at target doses of less than 2.0 mg/kg, with Grade ≥3 treatment-related adverse events (TRAEs) of 6%, no Grade ≥2 interstitial lung disease, and no drug discontinuations. In May 2025 , the U.S. Food and Drug Administration (FDA) granted Fast Track designation to ZL-1310 for treatment of ES-SCLC. Bemarituzumab (FGFR2b): In June 2025 , Zai Lab announced the Phase 3 FORTITUDE-101 clinical trial evaluating first-line bemarituzumab plus chemotherapy (mFOLFOX6) met its primary endpoint of overall survival (OS) at a pre-specified interim analysis.​ At the interim analysis, bemarituzumab plus chemotherapy significantly improved OS in patients with FGFR2b overexpression compared to chemotherapy alone. The most common treatment-emergent adverse events (>25%) in patients treated with bemarituzumab plus chemotherapy were reduced visual acuity, punctate keratitis, anemia, neutropenia, nausea, corneal epithelium defect and dry eye. While ocular events were consistent with the Phase 2 experience and observed in both arms, they occurred with greater frequency and severity in the Phase 3 bemarituzumab arm. Detailed results from FORTITUDE 101 will be shared at a future medical meeting. Zai Lab plans to move rapidly toward regulatory submission in China in the second half of 2025. Tumor Treating Fields (TTFields): In May 2025 , Zai Lab partner Novocure presented results from the Phase 3 PANOVA-3 trial for pancreatic cancer as a late-breaking oral presentation at the 2025 ASCO Annual Meeting. The data demonstrated that TTFields therapy, when added to standard of care, achieved an OS benefit supported by significantly improved quality of life and extended pain-free survival, a key outcome for patients with pancreatic cancer. Zai Lab participated in the study in Greater China (mainland China , Hong Kong , Macau and Taiwan , collectively) and plans to file for regulatory approval in China in the second half of 2025.​ In June 2025 , Zai Lab presented positive data from an ongoing, global Phase 1a/1b clinical trial of ZL-1310 for the treatment of patients with extensive-stage small cell lung cancer (ES-SCLC) at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting. In second-line (2L) SCLC, objective response rate (ORR) was 67% across all dose levels (n=33) and 79% at 1.6 mg/kg dose (n=14). ZL-1310 demonstrated a well-tolerated safety profile at target doses of less than 2.0 mg/kg, with Grade ≥3 treatment-related adverse events (TRAEs) of 6%, no Grade ≥2 interstitial lung disease, and no drug discontinuations. In May 2025 , the U.S. Food and Drug Administration (FDA) granted Fast Track designation to ZL-1310 for treatment of ES-SCLC. Immunology Pipeline Efgartigimod (FcRn): In July 2025 , the China Guidelines for the Diagnosis and Treatment of Myasthenia Gravis (MG) (2025) was published, emphasizing the importance of Minimal Symptom Expression (MSE), as the primary treatment goal in MG. The guidelines have highlighted VYVGART’s ability to achieve MSE rapidly and provide durable benefit. VYVGART is now recommended for early use in mild-to-moderate and highly active patients, and for sustained long-term treatment to maximize potential benefit. ZL-1503 (IL-13/IL-31R): In June 2025 , Zai Lab announced new preclinical data highlighting the potential of ZL-1503 as a promising treatment for moderate-to-severe atopic dermatitis and other IL-13 and IL-31-driven diseases. Its favorable preclinical safety profile, prolonged half-life and durable suppression of both inflammatory and pruritogenic pathways support the continued advancement of ZL-1503 toward clinical development.

Non-GAAP Measures In addition to results presented in accordance with GAAP, we disclose growth rates that have been adjusted to exclude the impact of changes due to the translation of foreign currencies into U.S. dollars. We have also presented a measure of adjusted loss from operations that adjusts GAAP loss from operations to exclude the impact of certain non-cash expenses including depreciation, amortization, and share-based compensation, which we refer to as “profitability.” These adjusted growth rates and adjusted loss from operations are non-GAAP financial measures. We believe that these non-GAAP financial measures are important for an understanding of the performance of our business operations and financial results and provide investors with an additional perspective on operational trends and greater transparency into our historical and projected operating performance. Although we believe the non-GAAP financial measures enhance investors’ understanding of our business and performance, these non-GAAP financial measures should not be considered an exclusive alternative to the corresponding GAAP financial measures.
