SEACOR Marine : SMHI Investor Presentation – April, 2023

Forward-Looking Statements discussed in this release as well as in other reports, materials and oral statements that SEACOR Marine Holdings Inc. ("SMHI" or the "Company") releases from time to time to the public constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Generally, words such as "anticipate," "estimate," "expect," "project," "intend," "believe," "plan," "target," "forecast" and similar expressions are intended to identify forward-looking statements and includes the information on Slide 26. Such forward-looking statements concern management's expectations, strategic objectives, business prospects, anticipated economic performance and financial condition and other similar matters. Forward-looking statements are inherently uncertain and subject to a variety of assumptions, risks and uncertainties such as the completion of our financial close process for the quarter, that could cause actual results to differ materially from those anticipated or expected by the management of the Company. These statements are not guarantees of future performance and actual events or results may differ significantly from these statements. Actual events or results are subject to significant known and unknown risks, uncertainties and other important factors, many of which are beyond the Company's control. It should be understood that it is not possible to predict or identify all such factors. Investors and analysts should not place undue reliance on forward-looking statements. Forward-looking statements speak only as of the date of the document in which they are made. The Company disclaims any obligation or undertaking to provide any updates or revisions to any forward-looking statement to reflect any change in the Company's expectations or any change in events, conditions or circumstances on which the forward-looking statement is based, except as required by law. It is advisable, however, to consult any further disclosures the Company makes on related subjects in its filings with the U.S. Securities and Exchange Commission, including Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K (if any). These statements constitute the Company's cautionary statements under the Private Securities Litigation Reform Act of 1995.

The financial results as of and for the three months ended March 31, 2023, included herein are preliminary, have not been reviewed or audited, are based upon the Company's estimates, and were prepared prior to the completion of the Company's financial statement close process for the quarter. The preliminary financial results should not be viewed as a substitute for the Company's full first quarter results and do not present all information necessary for an understanding of the Company's financial performance as of and for the quarter ended March 31, 2023. Accordingly, undue reliance should not be placed on this preliminary data.

Non-GAAP Financial Measures

This presentation includes certain non-GAAP financial measures. Direct Vessel Profit (defined as operating revenues less operating costs and expenses, "DVP"), when applied to individual vessels, fleet categories or the combined fleet. DVP is a critical financial measure used by the Company to analyze and compare the operating performance of its individual vessels, fleet categories, regions and combined fleet, without regard to financing decisions (depreciation for owned vessels vs. leased-in expense for leased-in vessels). DVP is also useful when comparing the Company's fleet performance against those of our competitors who may have differing fleet financing structures. DVP has material limitations as an analytical tool in that it does not reflect all of the costs associated with the ownership and operation of our fleet, and it should not be considered in isolation or used as a substitute for our results as reported under GAAP.

EBITDA is defined as net income (loss) before income taxes, interest income, depreciation and amortization. We believe that the presentation of EBITDA provides useful information to investors and management uses it to assess our on-going operations. Our use of EBITDA should not be viewed as an alternative to measures calculated in accordance with GAAP. EBITDA has limitations as analytical tool such as: (i) EBITDA does not reflect the impact of earnings or charges that we consider not to be indicative of our on-going operations, (ii) EBITDA does not reflect interest and income tax expense; and (iii) other companies, including other companies in our industry, may calculate EBITDA differently than we do. We do not provide a forward-looking reconciliation of EBITDA as the amount and significance of special items required to develop meaningful comparable GAAP financial measures cannot be estimated at this time without unreasonable efforts. These special items could be meaningful.
