Use of Non-GAAP Financial Measures

Adjusted EBITDA, Free Cash Flow, Non-GAAP Research and Development, Non-GAAP Selling, General, and Administrative, Non-GAAP Operating Expenses, Non-GAAP Loss from Operations, Non-GAAP Other Income (Expense), Non-GAAP Net Loss, and Non-GAAP Net Loss Per Share are non-GAAP financial measures. These non-GAAP financial 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 and liquidity. 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 provision for income taxes, interest income, interest expense, depreciation and amortization, stock-based compensation expense, change in fair value of warrant liability, loss on extinguishment of debt, certain one-time costs related to the IPO, transaction-related expenses, gain on settlement of contingent liabilities, and certain other items that are not expected to recur in the future or that management does not view as reflective of the performance of the business. 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.

Free Cash Flow

We define Free Cash Flow as net cash used in operating activities, less purchases of property and equipment and internal-use software. 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, after purchases of property and internal-use software, that (after any debt service requirements or other non-discretionary expenditures not otherwise deducted from the measure) 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 our changes in our cash conversion cycle.

Non-GAAP Research and Development

We define Non-GAAP Research and Development as research and development, adjusted for 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, adjusted for amortization of acquired intangibles, stock-based compensation expense, certain one-time costs related to the IPO, transaction-related expenses, and certain other items that are not expected to recur in the future or that management does not view as reflective of the performance of the business. 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 Operating Expenses

We define Non-GAAP Operating Expenses as operating expenses, adjusted for amortization of acquired intangibles, stock-based compensation expense, certain one-time costs related to the IPO, transaction-related expenses, and certain other items that are not expected to recur in the future or that management does not view as reflective of the performance of the business. 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 Loss From Operations

We define Non-GAAP Loss From Operations as loss from operations, adjusted for amortization of acquired intangibles, stock-based compensation expense, certain one-time costs related to the IPO, transaction-related expenses, and certain other items that are not expected to recur in the future or that management does not view as reflective of the performance of the business. 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 Income (Expense)

We define Non-GAAP Other Income (Expense) as other income (expense), adjusted for change in fair value of warrant liability, gain on settlement of contingent liabilities, loss on extinguishment of debt, and certain other items that are not expected to recur in the future or that management does not view as reflective of the performance of the business. 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 Net Loss

We define Non-GAAP Net Loss as net loss, adjusted for the income tax effect of business acquisitions, amortization of acquired intangibles, stock-based compensation, change in fair value of warrant liability, loss on extinguishment of debt, certain one-time costs related to the IPO, transaction-related expenses, gain on settlement of contingent liabilities, and certain other items that are not expected to recur in the future or that management does not view as reflective of the performance of the business. 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.
