## Questions

### Who owns Seneca Holdings and how is it funded?

The Seneca Nation of Indians owns Seneca Holdings outright. It is funded by tribal enterprise revenues — primarily gaming, hospitality, and retail operations — rather than outside limited partners. This sovereign ownership structure means the firm answers only to the Nation's elected leadership and broader membership.

### What does Seneca Holdings actually own?

The portfolio spans commercial real estate in Buffalo's Larkin District, a 55-megawatt solar development partnership with Alternative Energy Development Group, a fiber network on Cattaraugus Territory, the Highbanks Campground, and the Rochester Knighthawks professional lacrosse franchise. Climate tech exposure comes through a D-SAFE vehicle with Elemental Impact that backed Dimensional Energy.

### Does Seneca Holdings take outside capital or co-invest?

The firm does not raise third-party funds. Co-investment occurs through project-level partnerships — it has worked alongside Elemental Impact on climate venture D-SAFEs and Alternative Energy Development Group on solar infrastructure. These are structured as bilateral partnerships rather than a formal co-investor program.

### What is Seneca Holdings' connection to Core Scientific?

A Seneca Holdings board member serves on the board of Core Scientific, the publicly traded bitcoin mining and hosting firm. Core Scientific emerged from Chapter 11 restructuring in early 2024 and relisted on Nasdaq, retaining the board relationship with Seneca Holdings throughout the process.

### Where does Seneca Holdings invest geographically?

Activity concentrates heavily in Western New York — Buffalo commercial real estate, the Cattaraugus Territory fiber infrastructure, the Steamburg campground, and the Rochester Knighthawks franchise. Energy and climate investments extend nationally through partnerships, but the portfolio's center of gravity remains within or adjacent to Seneca ancestral lands.
