Item 8.01         Other Events.

As previously disclosed, on February 22, 2026, Tidewater Inc., a Delaware corporation (the “Company”), and certain of the Company’s subsidiaries (collectively, the “Tidewater Parties”), entered into a Sale and Purchase Agreement (the “Sale and Purchase Agreement”) to acquire all outstanding shares of Wilson Sons Ultratug Participações S.A. and Atlantic Offshore Services S.A. (collectively, the “Target Companies”) from Wilson Sons S.A., Ultranav International II, S.A. and Remolcadores Ultratug Limitada (collectively, the “Sellers”). In exchange, the Tidewater Parties will pay the Sellers an aggregate cash purchase price of $500,000,000 on a debt free, cash free basis, subject to adjustments, including a reduction for the assumption of the Target Companies’ debt, which was approximately $239.7 million as of March 31, 2026 (the “Transaction”).

Since announcing the Transaction, the Company has received all required local regulatory approvals, including approval from the Brazilian Antitrust Authority, and has obtained the change-of-control waivers required under the Target Companies’ primary credit facilities. The parties are continuing to complete documentation relating to the remaining closing matters, including amendments to the credit facilities, and now expect the Transaction to close sometime during the third quarter of 2026.

Disclaimer Regarding Forward Looking Statements

In accordance with the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, the Company notes that certain statements set forth in this communication are forward-looking statements which reflect our current view with respect to future events and future financial performance. Forward-looking statements are all statements other than statements of historical fact, including, without limitation, statements about the expected timing for completion of the transaction, and the parties’ ability to satisfy the conditions precedent and complete the transaction. All such forward-looking statements are subject to risks and uncertainties, many of which are beyond the control of the Company, and our future results of operations could differ materially from our historical results or current expectations reflected by such forward-looking statements. These risks and uncertainties include, without limitation: satisfaction of the conditions to completing the transaction; uncertainties as to the timing to consummate the transaction; the risk that regulatory approvals are not obtained or are obtained subject to conditions that are not anticipated by the parties; failure to obtain consents or waivers from the relevant third parties; potential adverse reactions or changes to business relationships resulting from the announcement or completion of the transaction; the effects of disruption to our and the sellers’ respective businesses; the effects of industry, market, economic, political or regulatory conditions outside of the parties’ control; transaction costs; our ability to achieve the benefits from the proposed transaction, including the anticipated cash flow generation and customer relationships; our ability to promptly, efficiently and effectively integrate the vessels into our own operations; unknown liabilities; and the diversion of management time on transaction-related issues. Other important factors that could cause actual results to differ materially from those in the forward-looking statements include: fluctuations in worldwide energy demand and oil and gas prices; fleet additions by competitors and industry overcapacity; limited capital resources available to replenish our asset base as needed, including through acquisitions or vessel construction, and to fund our capital expenditure needs; uncertainty of global financial market conditions and potential constraints in accessing capital or credit if and when needed with favorable terms, if at all; changes in decisions and capital spending by customers based on industry expectations for offshore exploration, field development and production; consolidation of our customer base; loss of a major customer; changing customer demands for vessel specifications, which may make some of our older vessels technologically obsolete for certain customer projects or in certain markets; rapid technological changes; delays and other problems associated with vessel maintenance; the continued availability of qualified personnel and our ability to attract and retain them; the operating risks normally incident to our lines of business, including the potential impact of liquidated counterparties; our ability to comply with covenants in our indentures and other debt instruments; acts of terrorism and piracy; the impact of regional or global public health crises or pandemics; the impact of potential information technology, cybersecurity or data security breaches; integration of acquired businesses and entry into new lines of business; disagreements with our joint venture partners; natural disasters or significant weather conditions; unsettled political conditions, war, civil unrest and governmental actions, such as expropriation or enforcement of customs or other laws that are not well developed or consistently enforced; risks associated with our international operations, including local content, local currency or similar requirements especially in higher political risk countries where we operate; interest rate and foreign currency fluctuations; labor changes proposed by international conventions; increased regulatory burdens and oversight; changes in laws governing the taxation of foreign source income; retention of skilled workers; enforcement of laws related to the environment, labor and foreign corrupt practices; increased global concern, regulation and scrutiny regarding climate change; increased stockholder activism; the potential liability for remedial actions or assessments under existing or future environmental regulations or litigation; the effects of asserted and unasserted claims and the extent of available insurance coverage; the resolution of pending legal proceedings; and other risks and uncertainties detailed in our most recent Form 10-K, Form 10-Qs and Form 8-Ks filed with or furnished to the Securities and Exchange Commission. If one or more of these or other risks or uncertainties materialize (or the consequences of any such development changes), or should our underlying assumptions prove incorrect, actual results or outcomes may vary materially from those reflected in our forward-looking statements. Statements in this communication are made as of the date hereof, and the Company disclaims any intention or obligation to update publicly or revise such statements, whether as a result of new information, future events or otherwise.
