## Questions

### Who runs investment decisions at Avidity?

Michael Gregory serves as Founder and Chief Investment Officer, holding ultimate authority over portfolio construction. David Brown is a Partner and Portfolio Manager. Gregory's investment approach was shaped during his tenure at Perceptive Advisors, where he managed healthcare portfolios before founding Avidity in 2013.

### Does Avidity participate in private investments or only public equities?

Avidity actively participates in private investments, particularly crossover rounds and pre-IPO financings. The firm has invested in private placements for companies such as Structure Therapeutics and held positions in Chinook Therapeutics prior to its acquisition by Novartis. This allows Avidity to build positions before companies reach public markets.

### How does the Shanghai office fit into Avidity's operations?

The Shanghai office provides Avidity with direct analytical access to Chinese biotech and pharmaceutical companies. It supports the firm's mandate to invest in China-based innovators, a structural advantage that most US-based healthcare hedge funds do not maintain. Specific personnel in the Shanghai office are not publicly disclosed.

### Which sectors does Avidity explicitly target or avoid?

Avidity targets the life sciences sector exclusively, including biotechnology, pharmaceuticals, and medical technology. The firm does not invest outside of healthcare and has no known positions in technology, financials, energy, or other sectors. This singular focus mirrors the model employed by other dedicated healthcare funds such as Baker Bros. Advisors.
