## Questions

### Who controls Joinn Laboratories?

Feng Yuxia co-founded the firm in 1995 and remains chairperson and controlling shareholder. Her spouse Zhou Zhiwen is also a co-founder. The founders' son, Zhou Fengyuan, owns Biorichland, a related-party real estate entity that leases facilities back to Joinn.

### What makes Joinn's investment model structurally different from other CROs?

Joinn owns and operates captive non-human primate breeding colonies across multiple sites in southern China. During periods of global NHP supply tightness, this gives Joinn a cost and availability advantage in preclinical studies and allows the firm to invest directly in drug-development programs while underwriting the service revenue.

### Does Joinn Laboratories invest directly in biotech companies?

Yes. Joinn acts as a corporate investor that takes direct equity stakes in early-stage biotech and pharmaceutical programs, often alongside its preclinical service agreements. The firm has publicly documented a co-investment relationship with Nexelis for bioanalytical studies servicing clinical trials in China.

### Where does Joinn derive its biologic assets?

Joinn maintains dedicated non-human primate breeding bases in Wuzhou (Guangxi Zhuang Autonomous Region), Yunnan, and Nanning. These captive colonies supply the firm's preclinical toxicology and pharmacology operations and function as a strategic asset held on its balance sheet.

### Does Joinn maintain operations outside of China?

The firm owns a commercial research property in Northern California, which extends its preclinical toxicology capabilities internationally and offers a regulatory foothold for clients pursuing FDA submissions.
