Its therapeutic portfolio spans multiple high-need areas—particularly oncology, autoimmune conditions, infectious diseases, and neurological disorders. By operating across Mainland China and Hong Kong while also supporting global-facing development efforts, Zai Lab aims to bring new treatment options to patients through both established medicines and an active pipeline of investigational assets.
From a business perspective, Zai Lab combines internal R&D capabilities with development and commercialization execution—typical of specialty biopharma companies that must continuously progress compounds from discovery into clinical development and then into market access. The company has already commercialized multiple products, including Zejula (a once-daily small-molecule PARP 1/2 inhibitor), Optune (a medical device technology leveraging tumor treating fields), NUZYRA (for specific acute bacterial skin/skin structure infections and community-acquired bacterial pneumonia), and Qinlock (indicated for gastrointestinal stromal tumors). Commercial revenue generally supports ongoing research activities, though specialty biopharma companies remain heavily investment-driven, especially when advancing late-stage pipeline candidates.
On the product and services side, Zai Lab’s value proposition is not only the sale of marketed therapies but also the translation of scientific programs into clinically validated medicines. Its pipeline includes oncology-focused and immunology/targeted-therapy candidates, such as Odronextamab (for B-cell lymphomas), repotrectinib (targeting ROS1 and TRK pathways), margetuximab (breast and gastroesophageal cancers), adagrasib (KRAS-G12C-mutated solid tumors), and bemarituzumab (gastric and gastroesophageal junction cancers). Additional investigational programs include EGFR-mutant strategies (e.g., CLN-081 and other EGFR inhibitors), checkpoint/PD-1-axis approaches (e.g., retifanlimab), and immune-mediated therapies such as efgartigimod.
In terms of cost and operational considerations, biopharmaceutical development typically involves substantial R&D and clinical costs (e.g., trial execution, regulatory submissions, medical affairs, and manufacturing scale-up). For companies like Zai Lab, “bill of materials” (BOM) analogs in life sciences often translate into component-like drivers such as clinical trial services, laboratory and manufacturing inputs, specialized drug substance/drug product costs, and quality/regulatory activities. The company’s operating model must balance near-term commercialization and ongoing pipeline investment—often reflected in working capital needs and cash burn patterns typical for growth-stage and late-stage development biopharma firms.
Key people include Founder/Chairperson/Chief Executive Officer Samantha Du, who founded the company and has been associated with its growth and public listing. Strategically, Zai Lab’s “wishes” or goals can be inferred from its focus areas: expanding patient access through commercial execution, accelerating pipeline progress across multiple modalities (small molecules, biologics, and devices), and strengthening clinical and regulatory momentum in its target indications. With an employee base of roughly 1,784 people, the company has the scale to support both commercial operations and ongoing development, enabling parallel progress across marketed products and future launches.

QoQQoQ means Quarter-over-Quarter. It compares the latest quarter with the immediately previous quarter to show short-term momentum changes.
RevenueThe total money that came through the front door from selling things, before paying a single bill. Think of it as the grand total of every credit card swipe from customers. (YoY compares this year to last year's performance, while QoQ compares the current three months to the previous three).

Free Cash FlowThe holy grail of corporate cash.

FCF MarginThe ultimate cash conversion rate. It shows how good the company is at turning regular sales directly into cold, hard, spendable cash. A high percentage means the business is an absolute cash-printing machine.

Operator: Hello, ladies and gentlemen. Thank you for standing by, and welcome to Zai Lab's Second Quarter 2026 Financial Results Conference Call. [Operator Instructions] As a reminder, today's call is being recorded. It is now my pleasure to turn the floor over to Christine Chiou, Senior Vice President of the Investor Relations. Please go ahead, ma'am.
Christine Chiou: Thank you, operator. Hello, and welcome, everyone. Today's earnings call will be led by Dr. Samantha Du, Zai Lab's Founder, CEO and Chairperson. She will be joined by Dr. Rafael Amado, President and Head of Global Research and Development; and Dr. Yajing Chen, Chief Financial Officer. Dr. Shan He, our Chief Business Officer; and Dr. Yizhe Wang, our operating partner, will also be available to answer questions during the Q&A portion of the call. As a reminder, during today's call, we will be making certain forward-looking statements based on our current expectations. These statements are subject to numerous risks and uncertainties that may cause actual results to differ materially from what we expect due to a variety of factors, including those discussed in our SEC filings. We will also refer to adjusted loss from operations, which is a non-GAAP financial measure. Please refer to our earnings release furnished with the SEC on August 6, 2026, for additional information on this non-GAAP financial measure. At this time, it is my pleasure to turn the call over to Dr. Samantha Du.
Ying Du: Thanks, Christine. Good morning, and good evening, everyone. Thank you for joining us today. Zai Lab has reached an important inflection point in its evolution from a regional business into a global biopharmaceutical company. We built this company by bringing first or best-in-class medicines to patients in China. Today, we are developing our own innovative medicines for patients worldwide with our first U.S. regulatory submission expected next year. The transformation reflects the R&D capabilities we have built. We're conducting global multiple center registrational oncology trials, advancing additional clinical programs across oncology and immunology and advancing our preclinical pipeline into INDs this year. Zoci, our potential first and best-in-class DLL3 ADC demonstrates what Zai Lab is capable of. We advanced it from IND to global pivotal trials in less than 2 years, reflecting the speed and efficiency of the integrated development organization we have built. By the end of this year, we expect to have 3 registrational programs in small cell lung cancer and neuroendocrine carcinoma. We're also evaluating Zoci in combination with T cell engagers through collaborations with Amgen and Boehringer Ingelheim. Our second major global opportunity is ZL-1503, a potential first-in-class long-acting IL-13L-31 bispecific for atopic dermatitis. We believe it has the potential to bring together multiple attributes in a single asset, robust skin clearance, rapid and durable reduction and longer dosing interval. …
