Data roadblocks make mapping and navigating biology difficult Reproducibility Crisis Multiple studies have shown that the vast majority of published academic literature cannot be recapitulated Analog Standard The fax machine is alive and well in medicine, while in biopharma, study results from CROs are still often reported as PDFs or scanned printouts Siloed Data in Pharma Biopharma has 100s of petabytes of scientific data stored on a project-by- project basis without the meta-data or annotation needed to relate it to other projects or questions in biology ! ! ! ! ! ! ! ! ! !

All industry data has been adapted from Paul, et al. Nature Reviews Drug Discovery. (2010) 9, 203–214. The cost to IND has been inflation- adjusted using the US Consumer Price Index (CPI) through 2023. The Recursion data shown for the transition stages and time to validated lead is the average of all Recursion programs since late 2017 through 2023. The Recursion data shown for cost to IND pertains to the actual and projected costs for a novel chemical entity to reach IND.

The Future of TechBio 19


 
TechBio Origins: Point Solutions Most BioTech companies have built a point solution - they’ve developed a tool, process, model or analysis to accomplish an important step in drug discovery. This is how we started too. But discovering and developing medicines requires hundreds of steps… 20


 
As these point solutions evolve they increase in complexity and scale We manipulate human cells with CRISPR/Cas9- mediated gene knockouts, compounds, and other reagents Phenom-1 Models trained on a library of >2 billion images and hundreds of millions of parameters learn to extract biologically meaningful signals FOUNDATION MODELS Diverse biological and chemical inputs PROFILING SYSTEMS Our highly automated wet-labs systematically capture images of human cells in response to perturbations (>250M phenotypic experiments) High-throughput screening AUTOMATION Maps of Biology & Chemistry DIGITIZATION >50 human cell types ~2M physical compounds >1M transcriptomes sequenced Models infer relationships between all possible combinations of genes and compounds, recapitulating known biology and revealing novel insights across multiple biological and chemical contexts >6 trillion relationships conducted every week 2.2M experiments Phenomics Up to 21


 
To truly industrialize drug discovery, point solutions must be integrated as modules across many diverse steps 22


 
Each module is complex, and we continuously improve them Prioritize compound synthesis for compounds predicted to have high likelihood of suitable pharmacokinetics DMPK In Vivo Validation Establish in vitro-in vivo and in silico-in vivo correlations to minimize experimental toil. ANIMAL PHARMACOKINETICSPre-synthesis Evaluation ENRICH FOR QUALITY A highly automated DMPK module executes critical assays across human and rat contexts. HT ADME Experiments WET LAB Leverage Recursion’s power for structure-based prediction of in vitro assays and in vivo compound profiles Predictive Models LEARNING CYCLES 23


 
Utilizing each module requires specialized teams and expertise InVivomic prioritization Digitized data collection yields real-time, continuous, and non-invasive data recorded in the animal’s home cage. Data generates high-dimensional assays, and ML connects studies for productivity. Overall, there is a drastic reduction in time, labor, and cost. Industrialized program progression GOING DIGITAL Compound optimization DETERMINING DOSAGE Not tolerated Tolerated ML evaluation of mice against >10 liabilities. Rat and mouse studies with ML-based selection of optimal compound and dose from video. Speed to insight, including tolerability liability Faster readouts for critical studies SPEED & EFFICIENCY 24


 
We continuously add new modules to improve the Recursion OS BioHive-2, Recursion’s next generation supercomputer, can analyze Tempus data and run ML oncology models. We believe that BioHive-2’s performance may place it in the top 50 of the next TOP500 list. ML trained on Tempus data BioHive-2 supercomputer COMPUTE The Tempus partnership provides Recursion with preferential access to multi-modal data for >100,000 oncology patients totaling >20 PB. >20 PB of real-world patient data DATASET We are using Tempus’ scaled multimodal real-world patient data to train AI models for target discovery, biomarker development, and patient selection. Combining forward & reverse genetics APPROACH 25


 
The result is a palette of ever-evolving sophisticated modules 26


 
We use different modules for different tasks: Find NCE for known target 27


 
We use different modules for different tasks: Find novel target & drug it 28
