BlackSky SPAC Presentation Deck

Confidentiality, Proprietary Information, and Forward Looking Statements (cont.) Use of Non-GAAP Financial Metrics. This presentation includes certain non-GAAP financial measures (including on a forward-looking basis) such as Adjusted EBITDA. These non-GAAP measures are an addition, and not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with GAAP. Reconciliations of non- GAAP measures to their most directly comparable GAAP counterparts are included in the Appendix to this presentation. BlackSky believes that these non-GAAP measures of financial results (including on a forward-looking basis) provide useful supplemental information to investors about BlackSky. BlackSky's management uses forward-looking non-GAAP measures to evaluate BlackSky's projected financials and operating performance. However, there are a number of limitations related to the use of these non-GAAP measures and their nearest GAAP equivalents, including that they exclude significant expenses that are required by GAAP to be recorded in BlackSky's financial measures. In addition, other companies may calculate non- GAAP measures differently, or may use other measures to calculate their financial performance, and therefore, BlackSky's non-GAAP measures may not be directly comparable to similarly titled measures of other companies. Additionally, to the extent that forward-looking non-GAAP financial measures are provided, they are presented on a non-GAAP basis without reconciliations of such forward-looking non-GAAP measures due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations.
