Exhibit 99.1

Investor Presentation Southland Holdings, Inc (SLND) September 2023

This presentation (together with oral statements made in connection herewith, the "Presentation") is for informational purposes only to assist current and prospective investors in making their own evaluation with respect to Southland Holdings, Inc. (“Southland”). This Presentation does not constitute an offer to sell, a solicitation of an offer to buy, or a recommendation to purchase any equity, debt or other financial instruments of Southland. The information contained herein does not purport to be all - inclusive and none of Southland, nor any of their respective subsidiaries, stockholders, affiliates, representatives, control persons, partners, members, managers, directors, officers, employees, advisers or agents (“Representatives”) make any representation or warranty, express or implied, as to the accuracy, completeness or reliability of the information contained in this Presentation. Current and prospective investors should consult with their own counsel and tax and financial advisors as to legal and related matters concerning the matters described here. Non - GAAP Financial Measures Backlog as presented in this presentation is an unaudited financial measure that is not presented in accordance with generally accepted accounting principles (“GAAP”). Southland defines backlog as a measure of the total amount of revenue remaining to be earned on projects that have been awarded. A project is included in backlog once Southland has an executed contract, or authorized notice to proceed. As a result, Southland believes backlog is firm, although cancellations or scope adjustments may occur. In Southland’s industry, backlog is an indicator of future revenue streams for work that has been awarded but not completed. Backlog should not be considered a comprehensive indicator of future revenue as contracts can be terminated by customers on relatively short notice, and backlog does not include future work for which Southland may be awarded. In the event of a cancelation, Southland is typically reimbursed for all of its costs through a specific contractual date, as well as its costs to demobilize from the project site. Southland’s contracts do not typically grant it rights to revenue reflected in backlog. Projects may remain in backlog for extended periods of time as a result of schedule delays, regulatory requirements, project specific issues, or other reasons. Contract amounts from contracts where a transaction price cannot be reasonably estimated are not be included within our backlog amount. Note that other companies may calculate backlog differently, and therefore backlog may not be directly comparable to similarly titled measures of other companies. Further, backlog is not a measure of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing financial results. Therefore, backlog should not be considered in isolation. Southland believes that backlog provides 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 backlog provides an additional tool for investors to use in evaluating ongoing operating results and trends. Southland’s calculation of backlog is subject to inherent limitations as it reflects the exercise of judgments by management. Forward - Looking Statements This presentation 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 presentation 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. In furnishing this Presentation, Southland and its Representatives expressly disclaim any obligation to update any information contained herein or to correct any omissions, inaccuracies, or errors.
