## Questions

### What is the relationship between Beijing BII Technology Development and the Beijing subway system?

Beijing BII Technology Development is the technology investment platform of Beijing Infrastructure Investment Co. (BII), the state-owned enterprise responsible for building and operating much of Beijing's subway network. The firm holds direct interests in subway communication income rights and owns Beijing Subway Civil Communication Transmission Systems. This concession-backed structure provides a recurring revenue base that the firm can deploy into venture investments.

### Who controls investment decisions at Beijing BII Technology Development?

The firm operates under the ultimate ownership of Beijing Infrastructure Investment Co., a municipal state-owned enterprise supervised by the Beijing SASAC. Cao Wei, the former chairman and executive director of the parent BII Group, has historically been the key figure. His son Cao Mingda holds a non-executive director role at the listed parent entity, BII Railway Transportation Technology Holdings. The specific investment committee structure is not publicly disclosed.

### Does Beijing BII Technology Development invest as a venture capital fund or as a corporate strategic investor?

It operates as a corporate venture and strategic investor rather than a traditional fund. The firm does not appear to raise third-party capital or report to limited partners. Its capital base is tied to operating infrastructure — specifically subway communication system revenue — rather than committed fund cycles, giving it a structural ability to hold positions over longer time horizons than typical VC funds.

### What investment stages does Beijing BII Technology Development target?

The firm invests across the full venture lifecycle, from seed and start-up through expansion and late-stage. Its mandate is broad within the infrastructure-technology nexus, favoring companies that can commercialize technologies proven in Beijing's transit ecosystem. Specific stage allocation weights are not publicly disclosed.

### How is Beijing BII Technology Development governed, and is it a truly state-controlled entity?

The firm is part of a state-owned group ultimately controlled by the Beijing municipal government through its SASAC. The governance structure includes both state-appointed directors at the parent level and family representation through Cao Mingda, son of former chairman Cao Wei, creating a hybrid oversight model. The listed parent, BII Railway Transportation Technology Holdings, trades on the Hong Kong Stock Exchange, adding a layer of public-market disclosure alongside state ownership.
