Zai Lab Limited reported third‑quarter 2025 revenue of $116.1 million, a 14% year‑over‑year increase from $101.8 million in Q3 2024, but a miss of $34.4 million against consensus estimates of $143.6 million to $150.5 million. Operating loss narrowed to $48.8 million from $61.2 million a year earlier, while adjusted loss stood at $28.0 million, a decline from $35.6 million in Q3 2024. The company’s adjusted earnings per share of –$0.33 fell short of the consensus range of –$0.25 to –$0.29, a miss of roughly 32%. In response, management lowered its full‑year 2025 revenue guidance to a minimum of $460 million, down from the $560 million to $590 million range reaffirmed in Q2 2025.
Revenue growth was driven primarily by strong performance of Nuzyra and Xacduro, which offset a decline in Zejula sales that fell 9% year‑over‑year due to intensified competition in the PARP‑inhibitor market. The combined effect of these product dynamics caused the revenue miss relative to analyst expectations, as the company’s top‑line growth was still below the $150 million consensus level. The miss also reflected a broader slowdown in the oncology market, which dampened demand for the company’s core assets.
Operating loss improvement was largely a result of disciplined cost management and a shift in the product mix toward higher‑margin assets. However, the company continued to invest heavily in research and development, particularly in its global pipeline, which contributed to the persistent adjusted loss. The narrowing of the operating loss from $61.2 million to $48.8 million indicates that the company is gaining operational leverage, but the ongoing R&D spend keeps the bottom line negative.
Management’s decision to lower full‑year revenue guidance signals caution about near‑term demand, especially in the U.S. market where competition is tightening. The new guidance of at least $460 million represents a reduction of $100 million to $130 million from the previous range, underscoring concerns about the pace of product launches and the impact of competitive pricing. The guidance still reflects confidence in the company’s China‑centric commercial engine, but it also highlights the need for stronger performance in the U.S. pipeline to meet earlier expectations.
The company highlighted two key pipeline milestones: KarXT was added to China’s national‑level schizophrenia treatment guidelines in September 2025, and a global registrational study for the DLL3 antibody‑drug conjugate zoci began in October 2025. These developments reinforce the company’s dual strategy of expanding its commercial footprint in China while advancing high‑potential global assets. Investors reacted negatively to the earnings miss, and the company’s cash position of $817.2 million as of September 30 2025 provides a cushion for continued investment in research and commercial activities.
Dr. Samantha Du, CEO, said the company is “entering a new growth phase powered by a rapidly advancing global pipeline and supported by a commercially profitable and scalable business in China.” CFO Yajing Chen noted that revenue growth was driven by Nuzyra sales, while Zejula sales declined amid evolving competitive dynamics. The comments underscore the company’s focus on balancing commercial success in China with the need to strengthen its U.S. pipeline to meet future growth targets.
