Investor Verification Checklist
- Verify the total outstanding debt load ($1.733 billion) and its impact on the company's leverage ratios.
- Review the specific amortization schedules in the Indenture (Exhibits 4.1 and 4.2) to understand future cash outflow requirements post-construction.
- Assess the "Completion Guarantee" obligation and the company's liquidity position to fund potential construction overruns.
- Monitor compliance with the "Excess Cash Flow" repurchase covenant, which could force debt reduction if the facility generates significant early cash flow.
- Confirm the timeline for the Barber Lake Facility completion, as this triggers the start of principal amortization payments.
