YD Bio Limited ("YD Bio Ltd" or the "Company") (NASDAQ:YDES), a biotechnology company advancing DNA methylation-based cancer detection technology and ophthalmologic innovations, today announced that its subsidiary YD Bio USA, Inc. ("YD Bio USA") entered into a Master Strategic Alliance Agreement (the "Agreement") with YC Biotech Co., Ltd. ("YC Biotech") on February 24, 2026. This partnership represents a pivotal advancement in the Company's mission, establishing YD Bio USA as the official strategic hub and exclusive U.S. Agent for regulatory applications to the U.S. Food and Drug Administration (the "FDA") for YC Biotech's Contract Research Organization ("CRO") clients in Asia.

Pursuant to the Agreement, the partnership will cover FDA-related projects, including Investigational New Drug ("IND"), New Drug Application ("NDA"), and Biologics License Application ("BLA") submissions, which will provide clients with a streamlined, integrated approach to navigating the complexities of the regulatory landscape. Through deep integration of YC Biotech's execution capabilities in Asia and YD Bio USA's experience engaging U.S. regulatory authorities, the companies will establish a "Taiwan-U.S. Dual-Core" regulatory platform.

Under the terms of the Agreement, YD Bio USA will serve as YC Biotech's exclusive U.S. Agent and formal liaison with the FDA. In this role, YD Bio USA will manage official communications and correspondence with the FDA, represent sponsors in pre‑IND and other formal regulatory meetings, provide high‑level U.S. regulatory pathway strategies and positioning advice, and serve as compliance risk advisor. YD Bio USA will also coordinate FDA inspection readiness efforts to facilitate compliance with applicable U.S. regulatory requirements.

YC Biotech will lead project acquisition and technical execution for clients with U.S. regulatory requirements and provide support for regulatory submissions. YC Biotech's responsibilities will also include preparation and drafting of comprehensive submission documentation, integration and scientific compilation of CMC (Chemistry, Manufacturing, and Controls) data, development of clinical protocols and regulatory content, overall project management to maintain timelines, and assembly of complete submission packages.

The collaboration will provide a one‑stop solution for a broad range of FDA‑related projects, including drug submissions such as IND, NDA, and BLA filings; medical device filings including Investigational Device Exemption ("IDE"), 510(k), De Novo, and Premarket Approval ("PMA") submissions; and strategic advisory services such as pre‑IND meeting facilitation, FDA inspection support, and ongoing regulatory strategy development.
