WuXi Biologics Achieves MSCI ESG AAA Rating and MSCI Selection Indexes Inclusion for Fourth Consecutive Year

• Maintained the highest MSCI AAA ESG Rating for the fourth consecutive year under the new ESG Model 5.0 (2026)
• Included in the MSCI ESG Selection Indexes for the fourth consecutive year
• Leader in Green CRDMO solutions for a healthier future

SHANGHAI, July 8, 2026 /PRNewswire/ -- WuXi Biologics (2269.HK), a leading global Contract Research, Development, and Manufacturing Organization (CRDMO), today announced that it has achieved MSCI's highest AAA ESG rating and been included in the MSCI 2026 Selection Indexes for the fourth consecutive year, underscoring global capital markets' recognition of the company's sustainability commitment and leadership in the biopharmaceutical industry.

This recognition is driven mainly by the evaluation of strong and sustained performance excellence across key ESG topics, including Product Safety and Quality, Human Capital Development, Corporate Governance and Corporate Behavior, and Climate Change. This year's rating is particularly meaningful as it was attained under MSCI ESG Model 5.0, the most significant revision since the rating system was established. Under the updated model, approximately 37% of rated issuers experienced rating changes, while WuXi Biologics successfully retained its AAA rating, demonstrating the robustness, adaptability, and long-term resilience of the company's ESG management system.

The MSCI Selection Indexes are designed to showcase the performance of companies with high ESG ratings relative to their sector peers. They are built especially for institutional investors seeking companies with a strong sustainability profile and a relatively low tracking error in relation to the underlying equity market. According to MSCI, the ETFs and ETF assets linked to the MSCI Sustainability and Climate Change indexes rank in the top globally among others.

Dr. Chris Chen, WuXi Biologics CEO and Chairman of the ESG Committee, commented, "We are honored to have once again achieved MSCI's highest AAA rating and been included in the MSCI Selection Indexes for the fourth consecutive year. This achievement validates our sustained efforts and continuous progress in sustainability. As a global leader in Green CRDMO, we consistently deliver ESG excellence, enable clients worldwide to fulfill their ESG commitments, and work with all stakeholders to promote responsible practices throughout the entire value chain."

Over the years, WuXi Biologics' consistent efforts to promote sustainable development have received notable recognition from leading global ESG rating agencies, including the EcoVadis Platinum Medal; a listing in Dow Jones Best‑in‑Class World Index and Emerging Markets Index; "A List" status from CDP for Climate Change, Water Security, and Supplier Engagement Assessment; the highest negligible-risk rating by Morningstar Sustainalytics, and designation as a Sustainalytics industry and regional ESG Leader; inclusion in the FTSE4Good Index Series; a "Prime" designation from ISS ESG Rating; and inclusion in the Hang Seng Corporate Sustainability Benchmark Index.
