Revenue Recognition
Contract Balances
The following table provides information about accounts receivables, contract assets, customer deposits and deferred revenue from contracts with customers (in thousands):

| | December 31, |
| | | 2025 | | 2024 |

| Accounts receivable | | $ | 371,796 | | | $ | 335,841 | |
| Contract assets | | 241,186 | | | 145,162 | |
| Customer deposits | | 78,207 | | | 220,115 | |
| Deferred revenue | | 65,608 | | | 66,304 | |
Contract assets relate to contracts for which revenue is recognized upon transfer of control of performance obligations, but where billing milestones have not been reached. Contract liabilities are represented by deferred revenue. Customer deposits and deferred revenue include payments received from customers or invoiced amounts prior to transfer of goods or services.
Contract assets and contract liabilities are reported in a net position on an individual contract basis at the end of each reporting period. Contract assets are classified as current in the consolidated balance sheets when the milestones other than the passage of time, are expected to be complete and the customer is invoiced within one year of the balance sheet date, and as long-term when both the above-mentioned milestones are expected to be complete, and the customer is invoiced more than one year from the balance sheet date. Contract liabilities are classified as current in the consolidated balance sheets when the revenue recognition associated with the related customer payments and invoicing is expected to occur within one year of the balance sheet date and as long-term when the revenue recognition associated with the related customer payments and invoicing is expected to occur in more than one year from the balance sheet date.

Deferred Revenue
Deferred revenue activity during the years ended December 31, 2025 and 2024, consisted of the following (in thousands):
| | | | | | | | | | | | | | | | | | |
| | | | Years Ended December 31, |
| | | | | | 2025 | | 2024 |
| | | | | | | | |
| Beginning balance | | | | | | $ | 66,304 | | | $ | 72,328 | |
| Additions | | | | | | 1,497,242 | | | 1,142,599 | |
| Revenue recognized | | | | | | (1,497,938) | | | (1,148,623) | |
| Ending balance | | | | | | $ | 65,608 | | | $ | 66,304 | |
Deferred revenue is equivalent to the total transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied, as of the end of the period. The primary component of deferred revenue at the end of the period consists of performance obligations relating to the provision of maintenance services under current contracts and future renewal periods. Some of these obligations provide customers with material rights over a period that we estimate to be largely commensurate with the period of their expected use of the associated products. As a result, we expect to recognize these amounts as revenue over a period of up to 21 years, predominantly on a relative stand-alone selling price basis that reflects the cost of providing these services. Deferred revenue also includes performance obligations relating to product acceptance and installation. A significant amount of this deferred revenue is reflected as additions and revenue recognized in the same 12-month period, and a portion of this deferred revenue is expected to be recognized beyond this 12-month period mainly due to deployment schedules.
As of December 31, 2025, we have unsatisfied performance obligations of $394.4 million, primarily related to product sales and installation services. We expect to recognize the associated revenue within the next 1 to 2 years, consistent with customers’ project deployment schedules. In addition, we had unsatisfied performance obligations of $25.0 million related mainly to deferred service contracts which we expect to recognize over the remaining contractual terms ranging from 1 to 26 years.
We do not disclose the value of the unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

Commitment to Issue Share-Based Consideration Payable to Customer’s Customer
On October 28, 2025, in connection with the partnership between the Company and Oracle Corporation (“Oracle”) to provide on-site solid state power for AI data centers, subject to the negotiation of a warrant mutually acceptable to the Company and Oracle, we agreed to issue to Oracle a warrant (the “Warrant”) to purchase up to an aggregate of 3,531,073 shares of Class A common stock, with an exercise price of $113.28 per share, closing market price on October 28, 2025. We and Oracle agreed that (i) the expiration date of the Warrant will be six (6) months from the date of the issuance of the Warrant, (ii) the Warrant will include customary anti-dilution adjustments, transfer restrictions and exercise procedures, and (iii) the Warrant will not entitle the holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise and settlement of the Warrant. This investment strengthens the partnership and its objective of accelerating the adoption of Bloom fuel cell technology for large scale AI data centers, specifically and onsite power generally. The Warrant and the shares underlying the Warrant are expected to be issued in reliance on the exemption from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended.
As of December 31, 2025, the Warrant had not been issued and no grant date had been established. Consistent with ASC 606 and ASC 718, as clarified by ASU 2025‑04, we measure the expected fair value of such share‑based consideration payable to customer’s customer and recognize it as a reduction of revenue when, or as, the related goods are transferred and installation obligations fulfilled. The expected fair value of the Warrant is estimated using a Black‑Scholes valuation model, consistent with ASC 718’s fair‑value measurement framework. We used the following weighted-average assumptions for determination of the Warrant fair value:
| | | | | | | | | | |
| | Year Ended December 31, 2025 | | |
| | | | |
| Risk-free interest rate | | 3.6% | | |
| Expected term (years) | | 0.5 | | |
| Expected dividend yield | | — | | |
| Expected volatility | | 96.2% | | |
As of December 31, 2025, the estimated total fair value of the Warrant was $55.9 million. Based on the proportion of product and installation obligations fulfilled under executed statements of work with the key hyperscaler as of December 31, 2025, we recognized $15.9 million of the Warrant’s fair value as an increase to Additional paid‑in capital, with a corresponding reduction to revenue, comprising $15.8 million within product revenue and $0.1 million within installation revenue. The remaining fair value will be recognized as a reduction of revenue as the related goods are transferred and installation obligations fulfilled under executed statements of work. We will update our estimate of the award’s fair value at each reporting date until a grant date is established, with any changes recorded as cumulative adjustments to revenue and Additional paid‑in capital.
