Note 4. Revenue from Contracts with Customers

Disaggregated revenue

Revenue disaggregated by reportable segment is presented in Note 20. Segments Information.

Contract balances

Contract assets relate to uncompleted Engineering contracts. As of December 31, 2025 and 2024, contract assets were $8.3 million and $6.5 million, respectively.

As of December 31, 2025 and 2024, the combined amount of contract liabilities and deferred revenue were $37.1 million and $26.1 million, respectively. In connection with the Rhodium Settlement described in Note 3. Acquisitions, the legacy hosting contract with Rhodium was terminated, thereby eliminating the Company’s future obligations under the contract. As a result, approximately $14.9 million of previously recognized deferred revenue was relieved and is included in Loss on contract settlement on the Consolidated Statements of Operations during the year ended December 31, 2025. The increase in contract assets was primarily attributable to the E4A Solutions Acquisition and significant third-party demand for Engineering products due to the increased interest in data center construction, as well as growing worldwide demand for power.

During the years ended December 31, 2025, 2024, and 2023, $10.4 million, $6.1 million, and $11.2 million, respectively, of the beginning balance of contract liabilities and deferred revenue was recognized as revenue.

During the years ended December 31, 2025, 2024, and 2023, $1.1 million, $3.5 million, and $0.7 million, respectively, was recognized as revenue as a result of satisfying performance obligations in previous periods.

Subsequent data center lease

In January 2026, the Company entered into the AMD Lease with AMD, a leading innovator in high-performance computing, graphics and visualization technologies, at the Rockdale Site. The AMD Lease includes an initial deployment of 25 MW of critical IT load capacity to be delivered in phases beginning in January 2026 and completing in May 2026, with the potential for additional expansion of up to a total of 200 MW of critical IT load capacity. The AMD Lease carries a term of 10 years, with three five-year extension options, and is expected to generate approximately $311.0 million in base rent over the initial term. In addition, AMD holds an expansion option for an additional 75 MW of critical IT load capacity and a right of first refusal for another 100 MW. If both options are exercised, AMD’s total leased capacity at the Rockdale Site would increase to 200 MW. As part of the AMD Lease, the Company began incurring tenant fit-out costs, which are anticipated to be reimbursed by AMD during 2026, for the construction of certain facilities to be used by AMD.

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
