PLEASE READ THE ANALYST CERTIFICATION AND IMPORTANT DISCLOSURES ON LAST PAGE MORE REPORTS FROM BLOOMBERG: RESP CMBR <GO> OR http://www.cmbi.com.hk 1 MN 4 Aug 2026 CMB International Global Markets | Equity Research | Company Update WuXi AppTec (603259 CH) WuXi AppTec (603259 CH) - Guidance raised after exceptional 2Q26 earnings Guidance raised after exceptional 2Q26 earnings WuXi AppTec delivered exceptionally strong results in 1H26, with growth accelerating through the year despite meaningful FX headwinds. In 1H26, total revenue rose 38.9% YoY to RMB28.9bn (2Q: +47.7% YoY), while revenue from continuing operations grew 48.0% YoY (2Q: +55.2% YoY). Adj. net profit surged 83.2% YoY to RMB11.6bn (2Q: +91.7% YoY), driving the adj. net margin to a record 40.0%. Demand visibility continued to improve, with backlog for continuing operations reaching RMB66.4bn as of 30 June. Mgmt. noted backlog/new bookings grew ~30%/ >40% YoY on a constant exchange basis. Mgmt. substantially raised full-year guidance by projecting 2026 revenue to reach RMB58.5-60.5bn (previously RMB51.3-53.0bn), with revenue from continuing operations to grow by 35-39% YoY (previously 18-22% YoY). Adj. net profit margin is expected to remain stable.  Broad-based growth led by Chemistry on capacity efficiency gains from late-stage and commercial projects. Mgmt. expected for greater success from several customers’ products, which we believe will be the main growth driver of the Chemistry segment in 1H26. Mgmt. emphasized that over 80% of commercial projects were converted internally from its own pipeline, and late-stage plus commercial projects now contribute more than 50% of revenue, a structural mix shift that underpins both growth durability and margin resilience. Specifically, small molecule D&M revenue jumped 72.7% YoY (2Q26: +66.9%), while TIDES revenue grew 44.3% YoY in 1H26 with 74.9% YoY growth in 2Q26, lifting full-year TIDES growth guidance to ~45% (from ~40%). Mgmt. attributed quarterly TIDES volatility to delivery scheduling and complex supply-chain planning, not underlying demand. Testing revenue rose 31.5% YoY (2Q: +35.1%), with safety assessment services up 42.8% YoY. Biology revenue steadily grew 11.2% YoY in 1H26 (2Q26: +12.3%). Mgmt. highlighted a recovery in global early-stage R&D demand over recent quarters, particularly in new modalities, and viewed AI-driven drug discovery as a positive factor for its early-stage business.  Capacity effectively running at full utilization. TIDES capacity is planned to reach 130k L by end-2026, with three new workshops under construction - two in Taixing (online in 2027) and one in Singapore (online in 2028). Small molecule capacity is targeted at 5mn L by end-2026. The construction of new Changzhou site was initiated ahead of schedule to accommodate demand. The increase of capex to RMB7.5–8.5bn reflects accelerated overseas construction and the early Changzhou start, with further potential rise over coming years. Wit
