Statements included in this press release that are not statements of historical fact, including statements about our expectations, beliefs, plans, strategies, objectives, prospects, assumptions or future events or performance, are forward-looking statements. Forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified.

Various risks that could cause actual results to differ from those expressed by the forward-looking statements included in this press release include, but are not limited to: our failure to manage our growth effectively and our ability to achieve and maintain profitability; the potential for delayed or failed launches, and any failure of our launch vehicles and spacecraft to operate as intended; our inability to manufacture our launch vehicles, landers, or orbital vehicles at a quantity and quality that our customers demand; the hazards and operational risks that our products and service offerings are exposed to, including the wide and unique range of risks due to the unpredictability of space; the market for commercial launch services for small- and medium-sized payloads not achieving the growth potential we expect; our dependence on contracts entered into in the ordinary course of business and our dependence on major customers and vendors; a loss of, or default by, one or more of our major customers, or a material adverse change in any such customer’s business or financial condition, could materially reduce our revenues and backlog; uncertain global macro-economic and political conditions, including the implementation of tariffs; disruptions in U.S. government operations and funding and budgetary priorities of the U.S. government; the failure of our information technology systems, physical or electronic security protections; the inability to operate Alpha at our anticipated launch rate (including due to potential regulatory delays) or finalize the development and delivery of Eclipse; our failure to establish and maintain important relationships with government agencies and prime contractors; the inability to realize our backlog; evolving government laws and regulations; our ability to remediate the material weakness with respect to our internal control over financial reporting and disclosure controls and procedures; our ability to implement and maintain effective internal control over financial reporting in the future; and other factors set forth in our filings with the Securities and Exchange Commission.

Use of Non-GAAP Financial Measures

Adjusted EBITDA, Non-GAAP Operating Expenses, Non-GAAP Research and Development, Non-GAAP Selling, General, and Administrative, Non-GAAP Other Expense, and Free Cash Flow are non-GAAP financial measures. These non-GAAP measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with U.S. GAAP. A reconciliation of each non-GAAP financial measure to the most directly comparable financial measure prepared in accordance with U.S. GAAP is included in the supplemental financial data attached to this press release. Non-GAAP financial measures have important limitations as analytical tools and should not be considered in isolation or as a substitute for analyses of Firefly’s performance or cash flows as reported under U.S. GAAP. Non-GAAP financial measures may be defined differently by other companies in our industry and may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

Firefly believes non-GAAP financial information provides additional insight into the Company’s ongoing performance. Therefore, Firefly provides this information to investors for a more consistent basis of comparison and to help them evaluate the Company’s ongoing performance and liquidity and to enable more meaningful period to period comparisons.

Adjusted EBITDA

We define Adjusted EBITDA as net loss adjusted for interest expense, net, provision for income taxes, depreciation and amortization, stock-based compensation expense, the change in fair value of warrant liabilities, loss on disposal of fixed assets, transaction costs, and other expenses. In addition to net loss, we use Adjusted EBITDA to evaluate our business, measure its performance, and make strategic decisions.

We believe that Adjusted EBITDA provides useful information to management, investors, and analysts in assessing our financial performance and results of operations across reporting periods by excluding items we do not believe are indicative of our core operating performance. Net loss is the U.S. GAAP measure most directly comparable to Adjusted EBITDA. Adjusted EBITDA should not be considered as an alternative to net loss. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.

Non-GAAP Operating Expenses

We define Non-GAAP Operating Expenses as operating expenses, less stock-based compensation expense, one-time costs related to the IPO, and loss on disposal of fixed assets. Management believes this non-GAAP measure provides investors with meaningful

img187228946_0.jpg

insight into results from ongoing operations by excluding items of income or loss to present it in accordance with how management manages the business.

Non-GAAP Research and Development

We define Non-GAAP Research and Development as research and development less stock-based compensation expense. Management believes this non-GAAP measure provides investors with meaningful insight into results from ongoing operations by excluding items of income or loss to present it in accordance with how management manages the business.

Non-GAAP Selling, General, and Administrative

We define Non-GAAP Selling, General and Administrative as selling, general and administrative less stock-based compensation expense and one-time costs related to the IPO. Management believes this non-GAAP measure provides investors with meaningful insight into results from ongoing operations by excluding items of income or loss to present it in accordance with how management manages the business.

Non-GAAP Other Expense

We define Non-GAAP Other Expense as other expense less change in fair value of warrant liabilities and certain other items that are not expected to recur in the future. Management believes this non-GAAP measure provides investors with meaningful insight into results from ongoing operations by excluding items of income or loss to present it in accordance with how management manages the business.

Free Cash Flow

We define Free Cash Flow as net cash used in operating activities, less purchases of property and equipment. We believe that Free Cash Flow is a meaningful indicator of liquidity that provides information to management and investors about the amount of cash generated from or used in operations that, after purchases of property and equipment, can be used for strategic initiatives, including continuous investment in our business and strengthening our balance sheet.

Free Cash Flow has limitations as a liquidity measure, and you should not consider it in isolation or as a substitute for analysis of our cash flows as reported under U.S. GAAP. Free Cash Flow may be affected in the near to medium term by the timing of capital investments, fluctuations in our growth and the effect of such fluctuations on working capital, and changes in our cash conversion cycle.

Disclaimer This presentation contains forward-looking statements (including within the meaning of Section 21E of the United States Securities Exchange Act of 1934, as amended, and Section 27A of the United States Securities Act of 1933, as amended) concerning Firefly. Statements included in this press release that are not statements of historical fact, including statements about our expectations, beliefs, plans, strategies, objectives, prospects, assumptions or future events or performance, are forward-looking statements. Forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified. In some cases, you can identify forward-looking statements by terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “objective,” “ongoing,” “plan,” “predict,” “project,” “potential,” “should,” “will,” “would,” or the negative of these terms or other comparable terminology. In particular, our guidance, outlook and forecasts for full-year 2025, statements about the markets in which we operate, including growth of our various markets, statements about potential new products and product innovation, our ability or expectations to establish new partnerships, our expectations regarding new vehicle launches and launch timelines, and our ability to retain existing customers and maintain their bookings are forward-looking statements. Accordingly, undue reliance should not be placed on such statements. Various risks that could cause actual results to differ from those expressed by the forward-looking statements included in this press release include, but are not limited to: our failure to manage our growth effectively and our ability to achieve and maintain profitability; the potential for delayed or failed launches, and any failure of our launch vehicles and spacecraft to operate as intended; our inability to manufacture our launch vehicles, landers, or orbital vehicles at a quantity and quality that our customers demand; the hazards and operational risks that our products and service offerings are exposed to, including the wide and unique range of risks due to the unpredictability of space; the market for commercial launch services for small- and medium-sized payloads not achieving the growth potential we expect; our dependence on contracts entered into in the ordinary course of business and our dependence on major customers and vendors; a loss of, or default by, one or more of our major customers, or a material adverse change in any such customer’s business or financial condition, could materially reduce our revenues and backlog; uncertain global macro-economic and political conditions, including the implementation of tariffs; disruptions in U.S. government operations and funding and budgetary priorities of the U.S. government; the failure of our information technology systems, physical or electronic security protections; the inability to operate Alpha at our anticipated launch rate (including due to potential regulatory delays) or finalize the development and delivery of Eclipse; our failure to establish and maintain important relationships with government agencies and prime contractors; the inability to realize our backlog; evolving government laws and regulations; our ability to remediate the material weakness with respect to our internal control over financial reporting and disclosure controls and procedures; our ability to implement and maintain effective internal control over financial reporting in the future; and other factors set forth in our filings with the Securities and Exchange Commission. You should not place undue reliance on these forward-looking statements, which speak only as of the date stated, or if no date is stated, as of the date of this press release. Actual results may vary from the estimates provided. We undertake no intent or obligation to publicly update or revise any of the estimates and other forward-looking statements made in this announcement, whether as a result of new information, future events or otherwise, except as required by law. Use of Non-GAAP Financial Measures Adjusted EBITDA, Non-GAAP Operating Expenses, Non-GAAP Research and Development, Non-GAAP Selling, General, and Administrative, Non-GAAP Other Expense, and Free Cash Flow are non-GAAP financial measures. These non-GAAP measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with U.S. GAAP. A reconciliation of each non-GAAP financial measure to the most directly comparable financial measure prepared in accordance with U.S. GAAP is included in the supplemental financial data attached to this press release. Non-GAAP financial measures have important limitations as analytical tools and should not be considered in isolation or as a substitute for analyses of Firefly’s performance or cash flows as reported under U.S. GAAP. Non-GAAP financial measures may be defined differently by other companies in our industry and may not be comparable to similarly titled measures of other companies, thereby diminishing their utility. Firefly believes non-GAAP financial information provides additional insight into the Company’s ongoing performance. Therefore, Firefly provides this information to investors for a more consistent basis of comparison and to help them evaluate the Company’s ongoing performance and liquidity and to enable more meaningful period to period comparisons. Adjusted EBITDA We define Adjusted EBITDA as net loss adjusted for interest expense, net, provision for income taxes, depreciation and amortization, stock-based compensation expense, the change in fair value of warrant liabilities, loss (gain) on disposal of fixed assets, transaction costs, and other expenses. In addition to net loss, we use Adjusted EBITDA to evaluate our business, measure its performance, and make strategic decisions. We believe that Adjusted EBITDA provides useful information to management, investors, and analysts in assessing our financial performance and results of operations across reporting periods by excluding items we do not believe are indicative of our core operating performance. Net loss is the U.S. GAAP measure most directly comparable to Adjusted EBITDA. Adjusted EBITDA should not be considered as an alternative to net loss. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. Non-GAAP Operating Expenses We define Non-GAAP Operating Expenses as operating expenses, less stock-based compensation expense, one-time costs related to the IPO, and loss on disposal of fixed assets. Management believes this non-GAAP measure provides investors with meaningful insight into results from ongoing operations by excluding items of income or loss to present it in accordance with how management manages the business. Non-GAAP Research and Development We define Non-GAAP Research and Development as research and development less stock-based compensation expense. Management believes this non-GAAP measure provides investors with meaningful insight into results from ongoing operations by excluding items of income or loss to present it in accordance with how management manages the business. Non-GAAP Selling, General, and Administrative We define Non-GAAP Selling, General and Administrative as selling, general and administrative less stock-based compensation expense and one-time costs related to the IPO. Management believes this non-GAAP measure provides investors with meaningful insight into results from ongoing operations by excluding items of income or loss to present it in accordance with how management manages the business. Non-GAAP Other Expense We define Non-GAAP Other Expense as other expense less change in fair value of warrant liabilities and certain other items that are not expected to recur in the future. Management believes this non-GAAP measure provides investors with meaningful insight into results from ongoing operations by excluding items of income or loss to present it in accordance with how management manages the business. Free Cash Flow We define Free Cash Flow as net cash used in operating activities, less purchases of property and equipment. We believe that Free Cash Flow is a meaningful indicator of liquidity that provides information to management and investors about the amount of cash generated from or used in operations that, after purchases of property and equipment, can be used for strategic initiatives, including continuous investment in our business and strengthening our balance sheet. Free Cash Flow has limitations as a liquidity measure, and you should not consider it in isolation or as a substitute for analysis of our cash flows as reported under U.S. GAAP. Free Cash Flow may be affected in the near to medium term by the timing of capital investments, fluctuations in our growth and the effect of such fluctuations on working capital, and changes in our cash conversion cycle.
