NON-GAAP FINANCIAL MEASURES In addition to results determined in accordance with U.S. generally accepted accounting principles (“GAAP”), this presentation contains Adjusted EBITDA, Adjusted EBITDA Margin, and Adjusted Imagery and Software Analytical Service Cost of Sales, excluding depreciation and amortization, which are non-GAAP financial performance measures. Adjusted EBITDA is defined as net income or loss attributable to BlackSky before interest income, interest expense, income taxes, depreciation and amortization, as well as significant non- cash and/or non-recurring expenses as our management believes these items are not as useful in evaluating the Company’s core operating performance. These items include, but are not limited to, stock-based compensation expense, unrealized (gain) loss on certain warrants/shares classified as derivative liabilities, litigation, settlements, and related costs, severance, income on equity method investment, investment loss on short-term investments, and transaction costs associated with debt and equity financings. We determine Adjusted EBITDA Margin by taking the ratio between our Adjusted EBITDA and our revenue and expressing such ratio as a percentage and Adjusted Imagery and Software Analytical Service Cost of Sales by taking our Imagery and Software Analytical Service Costs, excluding depreciation and amortization, minus our stock-based compensation expense. We determine total Gross Margin percentage by taking total revenue and reducing it by the imagery and software analytical service costs that exclude depreciation and amortization and reducing that by the professional and engineering service costs that exclude deprecation and amortization. We determine Software Analytical Margin by taking the imagery and software analytical service revenue and reducing it by the imagery and software analytical service costs that exclude deprecation and amortization. These non-GAAP financial measures should not be considered in isolation or as an alternative to measures of financial performance determined in accordance with GAAP. Please refer to the appendix herein and our SEC filings for a reconciliation of such non-GAAP financial measures to their most comparable measures reported in accordance with GAAP, and for a discussion of the presentation, comparability, and use of such metrics.
