## What Zymeworks does

Zymeworks is a company that uses protein engineering and drug chemistry to discover and develop next-generation antibody-based therapeutics for hard-to-treat diseases. Its structure-guided molecular modeling, combined with internal antibody discovery and generation technologies, supports an integrated drug development engine. Its pipeline of multifunctional therapeutics is built on multispecific antibody therapeutics (MSATs) and antibody-drug conjugates (ADCs) platforms, aimed at cancer, inflammation and autoimmune disease. Partnerships and collaborations are central to its strategy, as a source of funding for research and development and to share risk, particularly in late-stage development. Through an asset and royalty aggregation strategy, Zymeworks seeks to optimize future cash flows from a growing portfolio of licensed products and product candidates, including Ziihera (zanidatamab-hrii) and pasritamig. As its royalty portfolio matures and generates capital beyond the needs of its operations and strategic investments, the company may allocate capital to stock repurchases.

| Product or program | What it is | Stage |
|---|---|---|
| Ziihera (zanidatamab-hrii) | Licensed product in Zymeworks' royalty portfolio |  |
| Pasritamig | Licensed product or candidate in Zymeworks' royalty portfolio |  |
