Forward-Looking Statements Forward-Looking Statements discussed in this release as well as in other reports, materials and oral statements that SEACOR Marine Holdings Inc. ("SEACOR Marine" 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. Non-GAAP Financial Measures This presentation includes certain non-GAAP financial measures. Direct Vessel Profit (defined as operating revenues less operating costs and expenses including major repairs and drydocking 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. Adjusted EBITDA is defined as DVP less general and administrative expenses and lease expenses. We believe that the presentation of Adjusted EBITDA provides useful information to investors and management uses it to assess our on-going operations. Our use of Adjusted EBITDA should not be viewed as an alternative to measures calculated in accordance with GAAP. Adjusted EBITDA has limitations as analytical tool such as: (i) Adjusted EBITDA does not reflect the impact of earnings or charges that we consider not to be indicative of our on-going operations, (ii) Adjusted EBITDA does not reflect interest and income tax expense; and (iii) other companies, including other companies in our industry, may calculate Adjusted EBITDA differently than we do. Net Debt is defined as total debt (the most comparable GAAP measure, calculated as long-term debt plus current portion of long-term debt excluding discount and issuance costs) less cash and cash equivalents (including restricted cash). We believe that the presentation of Net Debt provides useful information to investors and management uses it to compare total debt less cash and cash equivalents across periods on a consistent basis. Reconciliation for each of these non-GAAP measures are included as an appendix to this presentation.

II. Market Outlook

------

![Slide 10](smhi-ex99_1s10.jpg)

Supportive Industry Fundamentals Global Offshore Project Capex by FID Year Commentary: 2024 and H1 2025 saw a decline in offshore project capex leading to a dip in OSV demand across most offshore basins Global offshore project capex expected to increase significantly over the next 18-24 months which provides a supportive environment for the OSV sector in the long-term Source: Clarksons Research Services, Rystad Energy. Commentary: Outlook for offshore oil and gas projects remains positive, with forecasted stable offshore exploration capex over the next several years Capex allocation towards deepwater regions, likely to drive demand for larger, high-spec OSVs and subsea Offshore Exploration Capex by Region

Balance Supply / Demand Current demand decline is <1% from the 2024 peak Adjusted utilization remains ~90% despite "weakness" Supply and demand balance remains tight: Demand remains high with adjusted utilization close to 90%, which is supportive of a 2026 rate rebound Utilization, when adjusted for stacked PSVs, is in practice 14-15% higher than total utilization Source: Clarksons Research Services, Clarksons Securities.

![Slide 12](smhi-ex99_1s12.jpg)

Continued Supply Side Constraints Stacked supply and stacking length PSV orderbook at ~5% of fleet Supply is Driving the Cycle: Supply side constraints continue to drive utilization for PSVs for market activity in general higher than anticipated year-to-date "Real" sideline capacity is less than 4% of the fleet and the orderbook indicates "zero" fleet growth going forward Source: Clarksons Research Services, Clarksons Securities.

Dayrates remain robust, but regional bifurcations more pronounced Dayrates remain resilient: large PSVs increase due to South America – small vessel fixtures on the lower side Average LTM fixtures across vessel classes at ~$26k per day – North Sea on the low side, with South America on top Source: Clarksons Research Services, Clarksons Securities.
