The Company was performing under two contracts as both a prime and subcontractor to the United States government to provide R&D services. The larger of these two contracts was modified and accounted for as a new contract in the quarter ending December 31, 2024. These contracts were not accounted for as revenue prior to September 30, 2024 as they were not in the ordinary course of business and the counterparties were not customers under GAAP. In September 2024, the Company was awarded a best effort cost-plus-fixed fee contract up to $ 16.0 million by the United States Department of the Navy’s Office of Naval Research (“ONR”) to research the suitability of its KARNO generator for Navy ships and stationary power applications. Under the agreement, the Company will provide R&D services through September 2026, including delivery of up to seven KARNO generators. The ONR contract represented a significant change in business strategy toward providing R&D activities in the ordinary course of business in addition to developing power generators for stationary and mobile applications. The Company now accounts for all three contracts under ASC 606 beginning in the quarter ending December 31, 2024. The remaining amounts of revenue that we may recognize under these contracts was up to $ 15.7 million as of December 31, 2024, which is expected to be recognized in 2025 and 2026.

These contracts were not accounted for as revenue prior to September 30, 2024 as they were not in the ordinary course of business and the counterparties were not customers under GAAP. In September 2024, the Company was awarded a best effort cost-plus-fixed fee contract up to $ 16.0 million by the United States Department of the Navy’s Office of Naval Research (“ONR”) to research the suitability of its KARNO generator for Navy ships and stationary power applications. Under the agreement, the Company will provide R&D services through September 2026, including delivery of up to seven KARNO generators. The ONR contract represented a significant change in business strategy toward providing R&D activities in the ordinary course of business in addition to developing power generators for stationary and mobile applications. The Company now accounts for all three contracts under ASC 606 beginning in the quarter ending December 31, 2024. The remaining amounts of revenue that we may recognize under these contracts was up to $ 15.7 million as of December 31, 2024, which is expected to be recognized in 2025 and 2026. </context>
