2023 Financial Highlights

Revenue

The Group's revenue increased to RMB 2,124 million with an increase of 114% YoY. The increase was mainly attributable to (i) the growth in the number of customers and projects, driven by rapid growth of the global ADC and broader bioconjugate outsourcing service market and the Group's established position as a leading ADC CRDMO service provider in that market and (ii) the advancement of many Group's projects into later stage and external projects into pipeline due to effective implementation of "win the molecule" strategy.

Gross profit and gross profit margin

The Group's gross profit increased by 114% YoY to RMB 560 million, with a gross profit margin of 26.3%, primarily driven by the strong revenue growth.

Adjusted net profit

Adjusted net profit for the period increased by 112% YoY to RMB 412 million. Margin of adjusted net profit remained stable at 19.4%.

Adjusted Diluted earnings per share (EPS)

Adjusted diluted EPS was RMB 0.38, up by 73% YoY.

2023 Business Highlights

• Our rapidly expanding and high-quality customer base has reached a cumulative total of 345, including global pharma and innovative biotech companies. Collectively, our clients have submitted 55 INDs with the strong support from our Group. Notably, 6 out of top 10 global pharmaceutical companies have actively partnered with us to develop ADC or XDC assets.
• The "Enable, Follow and Win the Molecule" strategy continued to drive sustainable and fast project growth. We signed 50 new integrated projects in 2023. As of December 31 2023, the Group's total ongoing integrated projects reached 143.

• Later-stage projects (Phase II and III) increased to 21 with 5 PPQ projects, setting the stage for the next chapter of growth.
• The Group has accomplished a diversified project base, covering both innovative ADC and broader bioconjugate projects. Total number of integrated ADC projects reached to 129. Number of integrated XDC projects increased to 14.

Technology Expertise and External Partnerships

• Evolved from WuXiDAR4™ technology platform, the Group has developed and introduced an upgraded proprietary version, WuXiDARx™ technology, aiming to meet clients' demands to develop highly homogeneous ADCs with a range of distinct DAR values. The products produced from the platform have enhanced stabilities and much better pharmacokinetic profiles.
• The Group announced multiple partnerships with prominent biotech or pharmaceutical companies, e.g., the partnership with GeneQuantum, SyntaBio, Multitude Therapeutics/HySlink and Intocell, to accelerate the discovery of preclinical ADC candidates (PCCs) and develop more novel bioconjugates, and improve the development efficiency and rate of success.

Capacity Expansion & Quality System

• The Group currently operates three sites in Wuxi, Changzhou and Shanghai. The Wuxi city site has reached an important milestone by realizing fully integrated "All-in-One" manufacturing within one single site. The site now can manufacture all four ADC components, i.e., mAb intermediate, payload-linker, bioconjugate drug substance (DS) and bioconjugate drug product (DP). This will greatly simplify the ADC supply chain and significantly shorten the manufacturing cycle time.
• The global uniquely designed dual-function line for mAb intermediate and bioconjugate drug substance is efficiently operational. It accelerates processes, reduces costs, streamlines workflows, and shortens project timelines.
• All company's manufacturing operations are compliant with GMP regulation of FDA, EMA, and NMPA, with 100% success on client and QP audits in 2023, which will ensure the innovative bioconjugate products manufactured in high quality.

• Guided by the Group's lean culture and enabled by the WBS (WuXi Business System), the Group integrated lean management principles and methods to drive continuous improvement and dedicated to improving the comprehensive competitiveness from multiple dimensions including quality, process, cost and efficiency.
• The Group continues to improve ESG governance and has established an ESG Committee chaired by the CEO.
