Firefly Aerospace Inc. Revenue Disclosure

Launch Revenue

The Company has contracts with commercial and government entities to provide launch and integration services for payloads requiring transportation into orbit via launch vehicles. These contracts may include milestone payments and deposits. The Company considers the performance obligation under these contracts to be the initiation of the launch and recognizes revenue at that point in time. When the contract contains multiple performance obligations, stand-alone selling prices are established for each performance obligation in the contract based on cost plus margin or market prices for similar goods and services.

The Company also enters into contracts with its customers to provide engineering services and related components, and to develop and provide licenses for intellectual property. In these cases, the Company’s performance obligation is satisfied over time since the tasks are performed according to the customer’s specifications, which creates an asset with no alternative use to the Company, for which the Company has an enforceable right to payment for performance completed to date. The measure of progress over time is based upon an input method using a cost-to-cost measure which best depicts the transfer of control to the customer. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Estimating the total cost at completion of a performance obligation requires management to make estimates related to items such as subcontractor performance, material costs and availability, labor costs and productivity, and the costs of overhead. If the estimate of total costs to be incurred for a performance obligation exceed the total estimate of revenue to be earned, a provision for the anticipated loss is recognized in the period the loss is identified. Engineering services billed hourly are recognized over time.

Spacecraft Solutions Revenue

Spacecraft Solutions revenue includes revenue from contracts with commercial and government entities to provide end-to-end services to integrate payloads into Blue Ghost and Elytra for transport to the Moon and on-orbit space domain awareness missions, respectively, as well as to develop and provide software, sensor, and data processing capabilities for national defense missions. These contracts include firm-fixed-price and cost-plus pricing structures. For commercial payload services we consider the performance obligation to be the integration and delivery of customer payloads to specified destinations. These contracts typically require that the customer make milestone payments as specific conditions and tasks are performed. For software, sensor, and data processing contracts, we consider the performance obligation to be the development and implementation of the contracted solution. These contracts require customers to make milestone payments as specific conditions and tasks are performed, or regular periodic payments as costs are incurred. Performance obligations are satisfied over time since either (1) the tasks are performed according to the customer’s specifications and create an asset with no alternative use to the Company, or (2) the customer receives and consumes benefits as work is completed and the Company has an enforceable right to payment for performance completed to date.

For Spacecraft Solutions arrangements, the measure of progress over time is based upon an input method using a cost-to-cost measure which best depicts the transfer of control to the customer. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Estimating the total costs at completion of a performance obligation requires management to make estimates related to items such as subcontractor performance, material costs and availability, labor costs and productivity, and the costs of overhead. If estimates

of total costs to be incurred on a contract exceed total estimates of revenue to be earned, a provision for the entire loss on the contract is recognized in the period the loss is incurred.

For all revenue streams, the Company considers customer payments that are contingent on the success of a mission or that are dependent on award criteria to be variable consideration. We assess the likelihood of success of a mission or achievement of contractual award requirements at inception and may defer the recognition of some or all of the variable consideration until success of the mission is assured or the award fee amount is determined.

The Company’s contracts may provide customers with termination for convenience clauses, which may or may not include termination penalties. In some contracts, the size of the contractual termination penalty increases closer to the scheduled launch date. At the inception of each contract, the Company evaluates the contract’s termination provisions and the impact on the accounting contract term (i.e., the period in which the Company has enforceable rights and obligations). This includes evaluating whether there are termination penalties and if so, whether they are considered substantive. The Company applies judgment in determining whether the termination penalties are substantive.

The Company has elected the following practical expedients for Launch and Spacecraft Solutions revenue: (1) the Company does not account for significant financing components if the period between revenue recognition and when the customer pays for the product or service will be one year or less, (2) the Company recognizes revenue equal to the amount it has a right to invoice when the amount corresponds directly with the value to the customer of the Company's performance to date, and (3) the Company does not account for shipping and handling activities as a separate performance obligation, but rather as an activity performed to transfer the promised good or service.

The Company includes in its computation of remaining performance obligations customer orders for which it has accepted signed sales orders. Due to their nature, time and materials contracts contain variable consideration; however, in general, the Company's performance obligations under time and materials contracts qualify for the “right to invoice” practical expedient. Under this practical expedient, the Company recognizes revenue over time, in the amount to which the Company has a right to invoice. In addition, the Company is not required to estimate such variable consideration upon inception of the contract and reassess the estimate each reporting period. The Company determined that this method best represents the transfer of services, as upon billing the Company has a right to consideration from a customer in an amount that directly corresponds with the value to the customer of the Company's performance completed to date. As of December 31, 2025, the aggregate amount of the transaction price allocated to remaining performance obligations was $684.9 million. The Company expects to recognize approximately 28.5% of its remaining performance obligations as revenue within the next 12 months. The remaining performance obligations are expected to be recognized over the next five years. The remaining performance obligations do not include variable consideration that was determined to be constrained as of December 31, 2025.

Contract Balances

Contract assets and liabilities reflect timing differences between the receipt of consideration and the fulfillment of performance obligations under a contract with a customer. Contract assets reflect performance obligations satisfied, and revenue recognized in advance of customer billings. Contract liabilities reflect consideration received in advance of the satisfaction of a performance obligation under a contract with a customer. Contract assets become trade receivables once the Company’s rights to consideration become unconditional. Such rights are considered unconditional if only the passage of time is required before payment of that consideration is due. Retainage represents a portion of the contract amount that has been billed, but that the contract allows the customer to retain until final contract settlement. Billings for such retainage balances are generally collected within one year of the completion of the project. Contract costs are those costs directly related to fulfillment of specified customer contracts. Contract assets are recorded within accounts receivable, net or other current assets, depending on whether they represent an unconditional right to consideration, and contract liabilities are recorded within deferred revenue on the consolidated balance sheets.

During the years ended December 31, 2025, and December 31, 2024, the Company recognized $77.7 million and $51.9 million, respectively, of revenue that was included in the contract liabilities balance at the beginning of each period.

Loss Contracts

The Company recognizes a contract loss when the current estimate of the consideration expected to be received is less than the current estimate of total estimated costs to complete the contract. For purposes of determining the existence or amount of a contract loss, the Company considers total contract consideration, including any variable consideration constrained for revenue recognition purposes. The Company may experience favorable or unfavorable changes in contract losses from time to time due to changes in estimated contract costs and modifications that result in changes to contract prices. The Company recorded contract loss provisions related to its Spacecraft Solutions revenue contracts of $8.0 million and $12.7 million during the years ended December 31, 2025 and 2024 respectively. The decrease in the recorded loss provision amount of $4.7 million during the year ended December 31, 2025 is due to continued progress made towards the completion of the contract and changes in estimated contract costs. There were no contract losses recognized during the year ended December 31, 2023.
