Material Changes Versus Prior Period
- Backlog Growth: The Company reported a material increase in sales backlog from $1.3 billion as of March 31, 2026. This growth supported the expansion of the AR Convertible Debentures facility.

Guidance, Risks, and Management Commentary
- Revenue Realization Risk: Management explicitly states that bookings do not guarantee revenue in the anticipated period. Projects are subject to delays, cancellations, government approvals, and third-party financing contingencies.
- Liquidity Impact: Failure of bookings to convert to revenue could materially reduce revenue, profitability, and liquidity.
- Unregistered Sales: The issuance of the Amended and Restated AR Convertible Debenture relied on the Section 4(a)(2) exemption from registration under the Securities Act of 1933.
