- No history of commercial operations, limiting the accuracy of forward-looking forecasts.
- History of negative operating cash flows and the potential for continued negative cash flow.
- Dependence on obtaining governmental approvals, permits, and financing.

Lock-Up Agreements: Sponsor and Key Holder shares are subject to lock-up periods expiring 12 months post-closing or upon the stock price reaching $15.00 (50% of shares) and $20.00 (100% of shares), whichever occurs first.
