No. S1700119110001)AssociateShenzhen We have more than 10 clientrequest meetings postourinitiation ontheAIDDsectorover last week. Key debates are asfollows: * Employed by a non-US affiliate of HSBC Securities (USA) Inc, and isnot registered/ qualified pursuant to FINRA regulations Interest in robustcapex with upcomingclinical validation.Investorsshowedstronginterestinthe fast-growingAI drug discovery (AIDD)sector.Our core thesis was broadly validated:Insilico is viewed asanasset-backedAIDD storywith higher visibility, while XtalPi’s modelisperceived as an AI-enabledplatformmodelwith self-developed pre-clinical pipeline.Thedifferencematters asinvestorsappreciateasset ownership: Insilico’srentosertib has reachedPhase III, while our broader screen covering globalAI drugpipelines (exhibit 1)isreinforcingthe scarcity value of clinicallyvalidated AI-discovered assets.We seeclinical validationasthe clearestsector-wide valuation differentiatorin 2H26. Still concernedoverrising competition.Investors worried frontier AIcompanies, CROs, pharmas and private platformswould enter AIDD, anddisruptive technologies maydullthe edge of existing platforms.We viewcompetition as a sign of afast-growingmarket rather than an immediatethesisdisruptor. Capable entrants can validate the technology andmayexpand the addressable market. We summarizemajor disruptivetechnologies, from generative protein design and agentic AI R&D to self-driving laboratories and frontier AI-biology platforms (exhibit 2).Further, wethinkthe strongest moat is shifting away from algorithms towardsproprietarybiology data, experimental feedback loops,and most importantly, clinicalvalidation. Insilico remains a meaningful leadervsearlier-stage competitors. Keycatalysts in 2027.First, overseas technology progress,particularlyIsomorphicLabs’(unlisted) potentialclinical transitioninend-2026(source: IntuitionLabs), will be a key eventforfrontier AI capabilities translatinginto clinical drug assets.We think capital and model capability still need1+years to be converted into Ph II/III clinicalproof. Second, continued clinicalprogress should supportvalidatingdifferentAIDDmodels. Third,newpartnerships in 2H26provide incrementalinvestmentforAIDD platform.
