6. CONFIDENTIAL Factors Contributing To Our Success Efficient Communication: Internal  Co-location facilitates clear communication of key issues and promotes problem-solving  All under one roof to provide rapid in vitro data generation and discussion External  Cloud-based informatics and ELNs ensure rapid dissemination of data to all parties  Constant client-focused interactions to agree most effective routes forward  Full-time dedicated experienced Project Leaders (lab-based scientists) Experience Counts: Tailored assay and reagent development Assay validity and reliability Rapid identification of efficient medicinal chemistry routes Interpretation of data generated

7. CONFIDENTIAL Project teams composed of problem-solving PhD medicinal chemists Extensive industry experience across a wide range of therapeutic areas Seamless integration with comp chem, bioscience and DMPK for optimal turnaround of design → make → test → analyse cycle First-class laboratory facilities and capabilities HTS / fragment library design, synthesis and purification (~1K compounds per month)

8. CONFIDENTIAL Decades of experience in generating computational models that provide key insights into molecular optimisation challenges Close collaboration with medicinal chemists and each client Support drug discovery projects at all stages: target analysis, hit id, hit- to-lead and lead optimisation

9. CONFIDENTIAL Staffed by expert bioscientists, many with 10-20 years of drug discovery experience gained in pharmaceutical research Considerable drug discovery experience with small molecules and biologicals across a broad range of therapeutic areas and biological target classes Expert at designing screening cascades, establishing and performing complex assays, e.g. biochemical, cellular and biophysical Flexibility to respond to changes in project demands

10. CONFIDENTIAL Protein Crystallography Affiliate company – strategic financial investment by Sygil Group Founded in 2015 at BioHub, Alderley Park Protein expression and production  Construct design, protein expression and protein purification  Supply in formats suitable for in vitro assays, HTS, biophysics assays, in vivo studies or X- ray crystallography  Expression in E.coli, baculovirus/insect cells and mammalian cells  Few millilitres to >20 litres X-ray crystallography  Sparse matrix crystallisation screens, along with relevant screens designed around any literature precedents  Tool compounds used to explore options for co-crystallisation  Initial hit may require further optimisation to improve size and quality of diffraction  Following X-ray data collection at the synchrotron, 3D structural representations are produced
