• The company may not achieve milestones or receive additional payments under its collaboration agreements.
• Regulatory agencies may impose additional requirements or delay the initiation of clinical trials.
• The impact of new or changing laws and regulations could adversely affect operations.
• Market conditions may impact the company's business and financial performance.
• Pandemics and other health crises could affect business, research, clinical development plans, timelines, and results of operations.
• Zanidatamab may not be successfully commercialized.
• The evolution of the company's business strategy related to anticipated and potential future milestones and royalty streams, and existing and potential new partnerships, may not be successfully implemented.
• Clinical trials may not demonstrate the safety and efficacy of any of the company's or its collaborators' product candidates.
• Assumptions and estimates regarding financial condition, future financial performance, and estimated cash runway may be incorrect.
• Inability to maintain or enter into new partnerships or strategic collaborations could limit growth.

Future Outlook

The company expects its existing cash resources, combined with anticipated regulatory milestone payments, to fund planned operations into the second half of 2027. It anticipates having three product candidates in active Phase 1 trials in the second half of 2025, with two additional product candidates on track to enter the clinic in 2026. The business strategy is evolving to anchor future growth around anticipated royalty and milestone streams from zanidatamab, supplemented by revenues from existing and new partnerships, aiming for a predictable, longer-term source of substantial and durable positive cash flows.

Management Comments

• "Continued progress across our strategic partnerships has further validated the strength and versatility of our Azymetric platform as well as our strategic partnership model, which enables broad and accelerated clinical development with the right collaborators. The achievement of key development milestones from these partnerships not only reinforces our scientific approach but also generated meaningful revenue, helping to offset our measured R&D cash burn." Kenneth Galbraith, Chair and Chief Executive Officer.
• "Importantly, we have maintained financial prudence while executing on critical R&D objectives, including the recent IND clearance of ZW251. With this development, we expect to have three product candidates in active Phase 1 trials in the second half of 2025, with two additional product candidates on track to enter the clinic in 2026. Together these developments demonstrate consistent execution across our R&D programs and long term business strategy." Kenneth Galbraith, Chair and Chief Executive Officer.
• "With anticipated topline data from the HERIZON-GEA-01 study expected in the fourth quarter of 2025, we are evolving our business strategy to help enhance long term-value for our shareholders through thoughtful capital allocation, while continuing to pursue a meaningful impact on patient outcomes through our R&D innovation." Kenneth Galbraith, Chair and Chief Executive Officer.
• "Given the strong potential we see for peak sales of zanidatamab, we believe we have a compelling opportunity to anchor our future strategy around anticipated royalty and milestone streams from Ziihera in BTC, GEA and other potential future indications, which we believe could provide a predictable, longer-term source of substantial and durable positive cash flows." Kenneth Galbraith, Chair and Chief Executive Officer.
• "We are encouraged by the clinical progress observed to date with our lead ADC candidate, ZW191, which utilizes our proprietary Topo1i payload, '519, and an optimized antibody. The clinical and translational alignment observed further supports our decision to advance ZW251 into the clinic, leveraging the same core components to expand the therapeutic potential of our ADC approach in hepatocellular carcinoma." Paul Moore, Ph.D., Chief Scientific Officer.
• "In parallel, this quarter we were pleased to present inaugural preclinical data from our first autoimmune and inflammatory disease program. ZW1528 has demonstrated promising preclinical activity against relevant benchmarks, showcasing the versatility of our technology beyond oncology and into broader therapeutic areas." Paul Moore, Ph.D., Chief Scientific Officer.

Industry Context

Zymeworks' Q2 2025 results highlight a successful execution of its strategic partnership model, a common and effective approach in the biotechnology industry to de-risk and accelerate drug development. The significant revenue from milestone payments for zanidatamab's approvals in China and Europe underscores the global demand for innovative HER2-targeted therapies, aligning with the industry's focus on precision oncology. The expansion of its wholly-owned pipeline into autoimmune and inflammatory diseases with ZW1528, alongside its strong oncology focus (ADCs, bispecific antibodies), reflects a broader industry trend of diversifying therapeutic areas to maximize platform utility and address unmet medical needs beyond cancer. The company's emphasis on a capital-efficient, royalty-driven model for long-term funding is a strategic move to ensure sustainable R&D operations in a highly capital-intensive sector.
