We will begin receiving royalty income once our customers launch these products in the market.

We are now putting our efforts towards the discovery of potential best-in-class molecules and new modalities molecules for customers. Currently,we support 15 pre-clinical projects for customers in new modalities that include Peptide/Peptide-Drug-Conjugation (PDC),protein degraders and oligonucleotides. Several of these projects are expected to file an IND in late 2022 or early 2023.

- The unique CRDMO and CTDMO business model of the Company continue to successfully drive record high financial performance.
