leveraged our integrated WuXi AppTec Investigational New Drug (IND) program

(WIND) to generate preclinical data and prepare global regulatory submissions of

IND packages,expediting the IND application process for many of our customers

worldwide. Customers signed 47 WIND service packages with us in the first quarter

of 2022.

ii. Drug safety evaluation services achieved strong revenue growth of 53% year-over-

year. We maintained our industry-leading position in Asia for drug safety evaluation

services that meet global regulatory requirements.

The Company has the largest discovery biology enabling platform,with more than 2,500 experienced scientists who provide comprehensive biology services covering all stages and therapeutic areas of drug discovery. The Company has established 3 centers of excellence for non-alcoholic steatohepatitis (NASH),anti-viral,neuroscience & aging.

The Company has a leading DNA Encoded Library (DEL) and compound generation platform. More than 1,100 customers globally now use our DEL services.

The Company announced the launch of Tetracycline-Enabled Self-Silencing Adenovirus (TESSA™) in March 2022. TESSA™ technology is a revolutionary and novel process for transfection-free,scalable manufacturing of adeno-associated virus (AAV),and the new data recently published in Nature Communications supports the benefits of this technology. It highlights that in the same manufacturing volume,TESSA™ vectors produced 10 times more AAV than plasmid-based technology. By end of first quarter 2022,we have 14 TESSA™ evaluation projects.

Gross profit declined in Q1-2022 largely due to under-utilized capacities of the newly built Shanghai Lin-gang site and the new testing facility in Philadelphia. With capacity utilization ramping up in the coming quarters,gross profit is expected to turn positive and increase.

- WuXi DDSU: business evolving to focus more on innovative drug discovery

Revenue from WuXi DDSU declined 21.6% to RMB241 million and adjusted non-IFRS gross profit declined 45.1% to RMB80 million,with a gross margin of 33.1%. DDSU's revenue decline was mainly attributed to business adjustments that aim to better serve the growing needs of clients in China for novel and differentiated products that will take longer to deliver INDs.

During the Reporting Period,our success-based drug discovery service unit filed INDs for 2 drug candidates and obtained 16 CTAs on behalf of China-based customers. As of March 31,2022,we have cumulatively submitted 146 new chemical entity IND filings with the NMPA and obtained 126 CTAs,with 1 project in NDA review stage,3 projects in Phase III clinical trials,16 projects in Phase II clinical trials,and 74 projects in Phase I clinical trials. Upon these products' successful launch to the market by our customers,we will begin receiving royalty income.

Among the 146 projects for which INDs were filed or are currently in clinical stage,about 70% of them rank in the top three in China in terms of drug development progress among same-class drug candidates.

Continuous Improvements in ESG Management and Performance

Management Comment

Dr. Ge Li,Chairman and CEO of WuXi AppTec,said,"We achieved record growth in the first quarter of 2022. Our revenue increased 71.2% YoY and our adjusted Non-IFRS net profit increased 85.8% YoY. WuXi AppTec's performance during the first quarter of 2022 underscores that our unique CRDMO and CTDMO business models continue to drive the rapid growth for our company and allow us to better enable customers worldwide."

"After the outbreak of Omicron in Shanghai at the end of the first quarter,we quickly implemented our business continuity plan to ensure the health of our employees whilst operating our business continuously. We effectively leveraged our global capacities and comprehensive capabilities to meet project delivery timelines and capture new business opportunities. If the Omicron outbreak in Shanghai can be largely contained by April,we expect 63-65% YoY revenue growth for the second quarter and 65-70% revenue growth for the full year of 2022. Our management team will closely monitor the development of the outbreak and will provide business updates when appropriate."

We also provide adjusted non-IFRS net profit attributable to owners of the Company and earnings per share,which further exclude realized and unrealized gains or losses from our venture investments and joint ventures. Neither is required by,or presented in accordance with IFRS.

To better reflect the operation results and key performance,the Company has adjusted the scope of the foreign exchange related gains or losses by adjusting only the gains or losses that the management believes irrelevant to the core business. The comparative financial figures for the comparable periods have been adjusted to reflect the change of the scope.

We believe that the adjusted financial measures used in this press release are useful for understanding and assessing our core business performance and operating trends,and we believe that management and investors may benefit from referring to these adjusted financial measures in assessing our financial performance by eliminating the impact of certain unusual,non-recurring,non-cash and non-operating items that we do not consider indicative of the performance of our core business. Such adjusted non-IFRS net profit attributable to owners of the Company,the management of the Company believes,is widely accepted and adopted in the industry the Company is operating in. However,the presentation of these adjusted non-IFRS financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with IFRS. You should not view adjusted results on a stand-alone basis or as a substitute for results under IFRS,or as being comparable to results reported or forecasted by other companies.
