Zai Lab Announces Second Quarter 2026 Financial Results and Recent Corporate Updates

Conference call and webcast today, August 6, 2026, at 8:00 a.m. ET (8:00 p.m. HKT)

Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688) today announced financial results for the second quarter of 2026, along with recent product highlights and corporate updates.

“Zai Lab is entering an exciting new chapter in our evolution,” said Dr. Samantha Du, Founder, Chairperson and Chief Executive Officer of Zai Lab. “Over the past several years, we have evolved from bringing innovative medicines to patients in China to becoming a global biopharmaceutical company developing our own differentiated medicines for patients around the world. Today, our innovation pipeline is rapidly maturing. We advanced zocilurtatug pelitecan (zoci), our potential best-in-class DLL3 antibody-drug conjugate (ADC), from Investigational New Drug (IND) to global Phase 3 in under two years, and our growing portfolio of internally developed medicines, including ZL-1503, gives us confidence that innovation will increasingly drive Zai Lab's next phase of growth. Meanwhile, we continue to strengthen our commercial business. This quarter, we sharpened our commercial focus, delivered sequential revenue growth, maintained commercial profitability, and laid the foundation for a return to meaningful growth in 2027. Together, these achievements position Zai Lab to create long-term value for patients and shareholders.”

“We are excited about the progress across our growing global pipeline, with three registrational studies expected to be underway by year end and the potential for our first U.S. regulatory submission next year,” said Rafael G. Amado, M.D., President, Head of Global Research and Development at Zai Lab. “Zoci has demonstrated a differentiated profile — strong systemic and intracranial activity with a favorable safety profile — that supports development across multiple treatment settings in small cell lung cancer (SCLC) and extrapulmonary neuroendocrine carcinomas (epNECs). In immunology, ZL-1503 has the potential to address both inflammation and itch through dual inhibition of IL-13 and IL-31. Combined with its extended half-life enabled by YTE modifications, we believe its differentiated profile has the potential to address significant unmet needs in one of the largest markets in immunology. We look forward to sharing important clinical updates for both programs in the second half of the year.”

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 measures. We believe that these non-GAAP 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 accompanying GAAP financial measures.
