1st Quarter 2024 Investor Presentation

May 2, 2024

Safe Harbor

This presentation includes certain financial measures that have not been prepared in a manner that complies with generally accepted accounting principles in the United States ("GAAP"), including, without limitation, Adjusted Gross Profit, Adjusted Gross Margin, EBITDA, Adjusted EBITDA and Pro Forma Adjusted EBITDA (collectively, the "non-GAAP financial measures"). These non-GAAP financial measures may exclude items that are significant in understanding and assessing the Company's financial results. Therefore, these measures should not be considered in isolation or as an alternative to measures of financial performance in accordance with GAAP. Management believes that these non-GAAP financial measures provide meaningful information to investors because they provide insight into how effectively we operate our business. You should be aware that these non-GAAP financial measures may not be comparable to similarly-titled measures used by other companies. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures can be found in the appendix of this presentation.

This presentation includes market data and other statistical information from third-party sources. Although CTOS believes these third-party sources are reliable as of their respective dates, CTOS has not independently verified the accuracy or completeness of this information.
