• Upon Closing, Hasten Biopharmaceuticals (SG) Pte. Ltd. will become an indirect wholly-owned subsidiary of the Company and its financial results will be consolidated into the Company's financial statements.

The Acquisition includes the Marketing Authorization Holder (MAH) rights, trademark and broad commercial rights for 14 branded chronic disease products owned by Hasten Biopharmaceuticals (SG) Pte. Ltd. across multiple countries and regions in the Asia Pacific region. For the financial year ended 31 December 2025, Hasten Biopharmaceuticals (SG) Pte. Ltd. recorded a normalized revenue of US$82,232,000 (approximately RMB566,299,000) with an EBITDA of US$27,273,000 (approximately RMB187,818,000).

Hasten Biopharmaceuticals (SG) Pte. Ltd. is principally engaged in the commercialization of prescription pharmaceutical products, with a strategic focus on chronic diseases and acute/critical care, particularly in the cardiovascular and metabolic segments. It has established a mature pan-Asia-Pacific commercialization platform supported by an experienced local team of approximately 120 dedicated field forces. With over 2 billion people in the core Asia Pacific market, the Asia Pacific region has a large and growing patient base and continues to face substantial unmet medical needs, particularly in chronic disease management.

Everest's product pipeline is focused on chronic disease therapeutic areas, including CKM (cardiovascular, kidney, and metabolic diseases), and the Company has established a leading innovative drug commercialization platform for chronic diseases in China. Beyond Mainland China, the Company's commercialized products, including NEFECON^®, VELSIPITY^® and XERAVA^®, are progressing through new drugs application (NDA) approvals and reimbursement processes in authorized Asian markets. The Acquisition is expected to accelerate the commercialization of the Company's existing products in Asian markets, support a faster ramp-up in overseas revenue contribution, and represent an important step in the Company's broader regional expansion strategy.

The Company also believes that the coming years may represent an important window of opportunity for the accelerated adoption of innovative Chinese medicines into the Asia Pacific region. Chinese innovation is becoming increasingly competitive in clinical value, affordability and accessibility, with growing alignment to the needs of healthcare systems and patients across the region. At the same time, regulatory pathways, market access frameworks and awareness of innovative therapies continue to improve. In such an environment, long-term success will depend not only on the quality of product assets, but also on the ability to build localized capabilities across regulatory, market access, medical affairs and commercialization which would create a competitive advantage for the Company in this growing region.

Everest Medicines is committed to becoming a leading global biopharmaceutical company in Asia. This acquisition would enable the Company to extend into the Asia Pacific region the commercialization capabilities it has already built and validated in China. This would allow the Company to strengthen its regional footprint, accelerate market entry and execution for both existing and future products, and build the infrastructure and local know-how required to support broader overseas expansion over time.
