Global Strategic Collaborations Fuel Continued Strong Revenue Growth

The Company's strong earnings growth was primarily driven by the continued execution and expansion of high-value strategic collaborations with global partners. Harbour BioMed has successfully transformed its proprietary technology platforms and licensing business into a robust and recurring revenue engine.

During the Reporting Period, several major strategic collaborations made significant contributions to revenue. In December 2025, the Company entered into a long-term global strategic collaboration with Bristol Myers Squibb (BMS) to jointly discover and develop next-generation multi-specific antibodies. Under the terms of the agreement, Harbour BioMed could receive payments totaling $90 million, as well as development and commercial milestones of up to $1.035 billion. The Company also expanded its strategic collaboration with AstraZeneca to include antibody-drug conjugates (ADCs) and T-cell engager (TCE) therapeutics. In addition, previously announced licensing partnerships with AstraZeneca, Otsuka, Pfizer, Windward Bio and other global pharmaceutical companies continued to generate meaningful revenue. To date, Harbour BioMed's proprietary technology platforms have been applied across more than 380 drug discovery programs spanning multiple therapeutic areas, with more than 20 molecules having advanced into IND-enabling studies or clinical development, reinforcing the Company's leadership in next-generation biologics innovation.

Beyond licensing collaboration, Nona Biosciences has entered a period of rapid growth. Revenue generated from its platform-based technology licensing and discovery services, together with milestone payments from existing collaborations, has become another important pillar of the Company's business. These collaborations not only reflect the strong recognition of the Harbour Mice^® platform by multinational pharmaceutical companies, innovative biotechnology companies and leading academic institutions worldwide, but also underscore Harbour BioMed's successful transformation into a sustainable cash-generating business with enhanced financial resilience and a significantly strengthened risk profile.

Technology Platforms and AI Innovation Strengthen the Value Foundation

Harbour BioMed has embraced artificial intelligence (AI) as a core strategic priority, integrating AI technologies throughout the entire drug discovery and development process. In October 2025, the Company launched the first fully human AI-powered heavy-chain-only antibody (HCAb) generation and screening model enabled by its proprietary Hu-mAtrIx™ AI platform, establishing a closed-loop workflow encompassing AI-driven design, intelligent screening and experimental validation. The model has already demonstrated strong performance, achieving a target hit rate of 78.5%, significantly improving both discovery efficiency and developability.

During the same month, Harbour BioMed initiated the AI + Biopharmaceutical Ecosystem Alliance, bringing together organizations including Insilico Medicine, Molecule Mind and more to systematically transform the drug discovery process through AI-enabled innovation.

In May 2026, the Company reported encouraging preclinical data for LET003, its first next-generation ACVR2A/2B-targeting monoclonal antibody developed using the Hu-mAtrIx™ AI platform. In June 2026, Harbour BioMed further strengthened its AI strategy by entering into a comprehensive long-term strategic partnership with BioMap, a global leader in foundation AI models for life sciences. Together, the two companies established MegaStream TechBio, a joint venture dedicated to developing innovative AI-enabled drug pipelines for the global market. By integrating proprietary datasets, domain-specific foundation models and a broad portfolio of innovative programs, MegaStream TechBio aims to build a next-generation AI drug discovery engine centered on intelligent wet-lab/dry-lab integration and personalized, multimodal, multi-attribute generative AI models.

Clinical Pipeline Continues to Unlock Long-Term Value

Harbour BioMed continues to make meaningful progress across its differentiated pipeline. The Company now has nearly 30 innovative product candidates spanning immunology, oncology, obesity and metabolic diseases, and central nervous system (CNS) disorders—therapeutic areas with significant unmet medical needs. Multiple programs have advanced into clinical development.

For respiratory and immunological diseases, batoclimab, the Company's anti-FcRn monoclonal antibody, is the first drug in China to have completed the full clinical development pathway from Phase 1 through pivotal clinical trials. The biologics license application (BLA) has been submitted, and the therapy has the potential to become an important treatment option across multiple autoimmune diseases. Phase 1 data for the Company's ultra-long-acting anti-TSLP antibody HBM9378 demonstrated a substantially extended half-life, supporting the potential for twice-yearly dosing and reinforcing its best-in-class potential. Initial Phase 2 data in asthma are expected in the second half of 2026, while the Phase 2 SIRIUS study in chronic obstructive pulmonary disease (COPD) has already dosed its first patients. Meanwhile, another ultra-long-acting, TSLP-targeting bispecific antibody, HBM7575, has dosed the first subject in its Phase 1 study for atopic dermatitis and recently received IND clearance for the treatment of asthma.

For immuno-oncology, HBM4003, the Company's anti-CTLA-4 heavy-chain-only antibody, has demonstrated best-in-class potential. In a Phase 2 study in microsatellite stable (MSS) metastatic colorectal cancer (mCRC), HBM4003 in combination with tislelizumab achieved an objective response rate (ORR) of 34.8% and a median progression-free survival (mPFS) of 4.2 months. Based on these encouraging results, the Company entered into a licensing agreement and equity partnership with Solstice Oncology in February 2026, receiving upfront consideration valued at over $105 million and being eligible for milestone payments of up to approximately US$1.1 billion.

In addition, the Company's HBM7004, a bispecific antibody for solid tumors, has received IND clearance from the U.S. Food and Drug Administration (FDA), while its IND application has been accepted by China's National Medical Products Administration (NMPA).

From its foundational proprietary technology platforms and AI-driven innovation to the advancement of a differentiated clinical pipeline and the execution of high-value global partnerships, Harbour BioMed has built a self-reinforcing innovation ecosystem.
