Non-GAAP Financial Measures

This press release includes certain unaudited financial measures not presented in accordance with generally accepted accounting principles (“GAAP”), including but not limited to earnings before interest, taxes, depreciation, and amortization (“EBITDA”), adjusted earnings before interest, taxes, depreciation, and amortization (“Adjusted EBITDA”), backlog, adjusted net income (loss), adjusted net income (loss) per share and certain ratios and other metrics derived therefrom. Note that other companies may calculate these non-GAAP financial measures differently, and therefore such financial measures may not be directly comparable to similarly titled measures of other companies. Further, these non-GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. Southland believes that these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Southland’s financial condition and results of operations. Southland also believes that these non-GAAP financial measures provide an additional tool for investors to use in evaluating ongoing operating results and trends. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which items of expense and income are excluded or included in determining these non-GAAP financial measures.

Please see the accompanying tables for reconciliations of the following non-GAAP financial measures for Southland’s current and historical results: adjusted net income (loss) per share attributable to common stock (a non-GAAP financial measure) to net income (loss) per share attributable to common stock; and adjusted net income (loss) attributable to common stock, and Adjusted EBITDA (non-GAAP financial measures) to net income (loss) attributable to common stock.

Forward-Looking Statements

This press release contains “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on Southland’s current beliefs, expectations and assumptions regarding the future of Southland’s business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of Southland’s control. Southland’s actual results and financial condition may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements.

Any forward-looking statement made by Southland in this press release is based only on information currently available to Southland and speaks only as of the date on which it is made. Southland undertakes no obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.
