On* August 31, 2026 (*Closing Date), we completed the acquisition (Wilson Acquisition) of all outstanding capital stock of Wilson, Sons Ultratug Participações S.A. (now known as Tidewater Offshore do Brasil S.A., WSUT) and Atlantic Offshore Services S.A. (together with WSUT, the Wilson Companies). We believe this acquisition significantly expands our presence in Brazil’s robust offshore market and strengthens our competitive position by adding Brazilian-built tonnage to our fleet. The Wilson Companies were managed under the common control of their previous owners and are presented here on an aggregate basis. As a result of the Wilson Acquisition, we acquired assets and assumed liabilities owned by the Wilson Companies and their wholly owned subsidiaries, which include a fleet of 22 platform supply vessels (Wilson Vessels). At the Closing Date, we paid an aggregate cash purchase price of $283.1 million, which was the original base purchase consideration of $500.0 million adjusted for the Wilson Companies' debt (net of cash), working capital and other adjustments as set forth in the Amended and Restated Sale and Purchase Agreement (SPA). The purchase price is subject to customary post-closing adjustments.

Assets acquired and liabilities assumed in the Wilson Acquisition were recorded at their estimated fair values as of the Closing Date under the acquisition method of accounting. The fair value estimates below are subject to adjustment during the post-closing measurement period, primarily consisting of the final valuation for various working capital items, tax and other liabilities existing on the Closing Date. The estimated fair values of certain assets and liabilities including long-lived assets and contingencies require judgment and assumptions. Adjustments* may*be made to these estimates during the post-closing measurement period, and those adjustments could be material.

Property and equipment acquired in the business combination consisted primarily of offshore support vessels. We recorded property and equipment acquired at estimated fair value of approximately $513.4 million. The fair values of the offshore support vessels were estimated by applying both an income approach, using projected discounted cash flows, and a market approach. We estimate that the remaining useful lives for the vessels acquired fall in the range ofone to 10 years, based on an original estimated useful life of 20 years. No goodwill was recognized in connection with this business combination.

Debt assumed in the business combination consisted primarily of construction and conversion loans. We recorded the debt assumed at estimated fair value of approximately $214.8 million after a net discount provision of approximately $14.2 million.

Business combination related costs for the Wilson Acquisition were expensed as incurred in general and administrative expense and consist of various advisory, legal, accounting, valuation and other professional fees totaling $10.2 million and $14.4 million for thethree andnine months ended* September 30, 2026*, respectively*.*

10

The provisional amounts for assets acquired and liabilities assumed are based on estimates of their fair values as of the Closing Date and were as follows:

Revenue and net loss for the Wilson Companies since the Closing Date were $17.1 million and $1.6 million, respectively, for both thethree andnine months ended* September 30, 2026*.

The unaudited supplemental pro forma results present consolidated information as if the business combination were completed on* January 1, 2025.The pro forma results include, among others, (i) an increase in depreciation expense for adjustments to property and equipment and (ii) the amortization of the discount on the debt measured at fair value. The pro forma results donot* include any potential synergies or non-recurring charges that* may*result directly from the business combination.

Expected credit losses are recognized on the initial recognition of our trade accounts receivable and contract assets. In each subsequent reporting period, even if a loss hasnot yet been incurred, credit losses are estimated and recognized based on the history of credit losses and current conditions, as well as reasonable and supportable forecasts affecting collectability. We utilize a model to estimate the expected credit losses applicable to our trade accounts receivable and contract assets. This model considers our historical performance and the economic environment, as well as the credit risk and its expected development for each segmented group of customers that share similar risk characteristics. In addition, we establish specific allowances for credit losses for certain customer balances that we deem uncollectable. It is our practice to write off receivables when all legal options for collection have been exhausted.

Activity in the allowance for credit losses for thenine months ended* September 30, 2026* and2025 is as follows:

See Note (14) - “Segment and Geographic Distribution of Operations” for revenue by segment and in total for the worldwide fleet.

Contract Balances

At* September 30, 2026*, we had $0.5 million of deferred mobilization costs included within Prepaid expenses and other current assets and $0.7 million of deferred mobilization costs included in Other assets. At* December 31, 2025*, we had $0.8 million of deferred mobilization costs included with Prepaid expenses and other current assets and $1.1 million of deferred mobilization costs included in Other assets.

At* September 30, 2026*, we had $1.4 million of deferred mobilization revenue included within Accrued expenses and $0.8 million of deferred mobilization revenue included in Other liabilities that will be recognized from2026 through2028. At* December 31, 2025*, we had $4.8 million of deferred mobilization revenue included within Accrued expenses and $3.6 million of deferred mobilization revenue included in Other liabilities.

During thenine months ended* September 30, 2026* and2025, the amount of revenue recognized that was included in deferred mobilization revenue at the beginning of the period was $6.9 million and $8.6 million, respectively.

Earnings per share

For thenine months ended* September 30, 2026* and2025, we reported net income from operations. Our diluted earnings per share for these periods is based on our weighted average common shares outstanding and is computed using the treasury stock method for our outstanding “in-the-money” warrants and restricted stock grants (both time and performance based) awarded as part of our share-based compensation and incentive plans.

Accumulated Other Comprehensive Income

The following tables present the changes in accumulated other comprehensive income (OCI) by component, net of tax:

Dilutive Equity Instruments

The following table presents the outstanding number of common shares, “in-the-money” warrants and restricted stock units:

No warrants, restricted stock awards or restricted stock units, whether in the money or out of the money, are included in our earnings per share calculations if the effect of such inclusion is antidilutive.

Common Stock Repurchases

On* February 27, 2025,our Board of Directors (Board) approved a $90.3 million share repurchase program, and then on August 1, 2025,our Board approved a new $500.0 million share repurchase program. During thethree* andnine months ended* September 30, 2026*, we repurchased and retired 95,018 shares for approximately $7.9 million, excluding commissions and a 1% excise tax. No shares were repurchased during thethree months ended* September 30, 2025.During thenine* months ended* September 30, 2025,*we repurchased and retired 2,290,204 shares for approximately $90.0 million, excluding commissions and a 1% excise tax.

Income tax rates and taxation systems in the jurisdictions where we and our subsidiaries conduct business vary and our subsidiaries are frequently subjected to minimum taxation regimes. In some jurisdictions, tax liabilities are based on gross revenues, statutory deemed profits or other factors, rather than on net income. We use a discrete effective tax rate method to calculate taxes for interim periods instead of applying the annual effective tax rate to an estimate of the full fiscal year due to the level of volatility and unpredictability of earnings in our industry, both overall and by jurisdiction.

For thenine months ended* September 30, 2026*, income tax expense differs from the tax effect of the U.S. rate due to tax liabilities in various jurisdictions based on either revenue (deemed profit regimes) or pre-tax profits, international activity that generated income subject to U.S. tax, and the impact of Pillar Two.

During thenine months ended* September 30, 2026*, a gain on sale of a vessel was recognized in connection with an internal restructuring to reposition the vessel for strategic opportunities. This transaction resulted in $2.9 million of Pillar Two top-up tax and was included as Subpart F income and subject to U.S. taxation. Due to the internal nature of this transaction, this gain isnot reflected in the consolidated financial statements leading to a higher effective tax rate. The total expense accrual related to Pillar Two is approximately $13.6 million. We also generated U.S. tax expense of $22.6 million, primarily related to Net CFC Tested Income (NCTI) and Subpart F income.

During thenine months ended* September 30, 2025,*after assessing relevant positive and negative evidence, we released our valuation allowance against our entire U.S. net operating loss (NOL) balance totaling approximately $27.0 million.

The tax liabilities for uncertain tax positions are primarily attributable to permanent establishment considerations related to foreign jurisdictions, subpart F income inclusions and withholding taxes on foreign services. Penalties and interest related to income tax liabilities are included in income tax expense. Income tax payable is included in other current liabilities.

As of* December 31, 2025*, our balance sheet reflected approximately $528.4 million of net deferred tax assets prior to a valuation allowance of $332.0 million. As of* September 30, 2026*, we had net deferred tax assets of approximately $465.2 million prior to a valuation allowance of $348.1 million. The net deferred tax assets amount as of* September 30, 2026*, include $58.4 million of deferred tax liabilities from the Wilson Acquisition, consisting of a deferred tax asset of $1.7 million offset by a valuation allowance of $1.7 million and $58.4 million of deferred tax liabilities.

Management assesses all available positive and negative evidence to permit use of existing deferred tax assets.

With limited exceptions, we areno longer subject to tax audits by U.S. federal, state, local or foreign taxing authorities for years prior to* December 2021.We are subject to ongoing examinations by various foreign tax authorities and donot* believe the results of these examinations will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

U.S. Defined Benefit Pension Plan

We sponsor a defined benefit pension plan (pension plan) that was frozen in2010 covering certain U.S. employees. Actuarial valuations are performed annually. We contributed $0.3 million and $0.9 million to the pension plan during thenine months ended* September 30, 2026and2025*, respectively, and expect to contribute an additional $0.1 million to the pension plan during the remainder of2026.

Supplemental Executive Retirement Plan

We support a non-contributory and non-qualified defined benefit supplemental executive retirement plan (supplemental plan) that was closed to new participants in2010. We contributed $0.9 million and $0.9 million to the supplemental plan for thenine months ended* September 30, 2026and2025*, respectively, and expect to contribute $0.3 million during the remainder of2026. Our estimated obligations under the supplemental plan were $14.1 million and $14.0 million at* September 30, 2026* and* December 31, 2025*, respectively, and are included in “accrued expenses” and “other liabilities” in the Condensed Consolidated Balance Sheets.

Net Periodic Benefit Costs

The net periodic benefit cost for our pension plans and supplemental plan (collectively, Pension Benefits) is comprised of the following components:

The components of the net periodic pension cost are included in the caption “Interest income and other, net.”

Currency Devaluation and Fluctuation Risk

Due to our international operations, we are exposed to foreign currency exchange rate fluctuations against the U.S. dollar. For some of our international contracts, a portion of the revenue and local expenses are incurred in local currencies with the result that we are at risk for changes in the exchange rates between the U.S. dollar and foreign currencies. To minimize the financial impact of these items, we attempt to contract a significant majority of our services in U.S. dollars. In addition, we attempt to minimize the financial impact of these risks by matching the currency of our operating costs with the currency of our revenue streams when considered appropriate. We continually monitor the currency exchange risks associated with all contractsnot denominated in U.S. dollars. In recent years, laws impacting our operations in certain African countries require our customers to pay us onshore in local currency rather than offshore in U.S. dollars, subjecting us to heightened currency risk and restrictions on the repatriation of cash. As a result, we have accumulated cash in these countries. We continue to take steps to mitigate this additional foreign currency and repatriation risk with a focus on reducing cash balances denominated in currencies other than the U.S. dollar. Despite our efforts to mitigate currency risk, we* mayreport significant realized and unrealized currency-related gains or losses in our statement of operations. Beginning in thesecond* quarter of2025, we entered into derivative contracts to assist us in managing our foreign currency risk. See Note (11) - “Fair Value Measurements” and Note (13) - “Derivative Instruments and Hedging Activities” for activity and disclosure related to our foreign currency derivative contracts.

Legal Proceedings

In2009, on behalf of the Venezuelan government, Petróleos de Venezuela, S.A. (PDVSA), the national oil company of Venezuela, took possession of our assets and operations in Venezuela. In connection with this expropriation, we fully wrote-down our Venezuelan assets and initiated international arbitration. In2019, we converted our final international award into a U.S. federal court judgment, which we perfected pursuant to a writ of attachment against the shares held by PDVSA in PDV Holding, Inc. (PDVH), the parent company of CITGO Petroleum Corporation. The Delaware District Court (Court) ordered a public sale of the PDVH shares (the PDVH Sale) to satisfy the various judgments against Venezuela inCrystallex International Corp. v. Bolivarian Republic of Venezuela,No. 17-mc-151-LPS (D. Del.). On* July 2, 2025,the Court appointed Special Master filed its final recommendation for the winning bid for the PDVH Sale, which included listing the Tidewater subsidiaries holding judgment as thesecond* most senior creditor. On* November 25, 2025,the Court approved the Special Master’s recommended purchaser; however, an appeal is pending before the U.S. Court of Appeals for the Third Circuit, with a hearing held on October 21, 2026.*

Closing of the PDVH Sale and the collection of our judgment, if at all, are highly uncertain and present significant practical and legal challenges, including, without limitation, satisfaction of numerous closing conditions, including regulatory approval by the Office of Foreign Assets Control, and the positive final outcome of numerous claims filed by other parties opposing the PDVH Sale. We can provideno assurances regarding the timing or ultimate outcome of this case. As of* September 30, 2026*, the value of our judgment, including interest and $4.6 million of reimbursable fees we have paid to the Special Master, was approximately $87.0 million. However, given the collection uncertainty,no amount had been recorded in our financial statements related to this gain contingency.

In addition to the foregoing, we are named defendants or parties in certain lawsuits, claims or proceedings incidental to our business and involved from time to time as parties to governmental investigations or proceedings arising in the ordinary course of business. Although the outcome of such lawsuits or other proceedings cannot be predicted with certainty and the amount of any liability or gain that could arise with respect to such lawsuits or other proceedings cannot be predicted accurately, we donot expect these matters to have a material adverse effect on our financial position, operating results or cash flows.

Other Financial Instruments

Our primary financial instruments consist of cash and cash equivalents, restricted cash, trade receivables and trade payables with book values that are considered to be representative of their respective fair values. The carrying value for cash equivalents is considered to be representative of its fair value due to the short duration and conservative nature of the cash equivalent investment portfolio.

We periodically enter into derivative contracts to manage our exposure to foreign currency risk. These derivative contracts, which are placed with major financial institutions, generally take the form of forward contracts with a duration of less than12 months. We report derivative instruments on the balance sheet as either assets or liabilities measured at fair value. Changes in fair value are recognized currently in earnings unless specific hedge accounting criteria are met. We generally donot designate our derivative instruments as hedges for accounting purposes, therefore, any gains or losses resulting from changes in fair value of outstanding derivative financial instruments and from the settlement of derivative financial instruments are recognized in earnings and included as a component of foreign exchange gain (loss) in the Condensed Consolidated Statements of Operations.

We held derivative instruments related to foreign exchange contracts recorded as current assets, which were measured at their approximate fair value of $1.3 million (Level2) as of* September 30, 2026*. We held derivative instruments related to foreign exchange contracts recorded as other current assets and current liabilities, which were measured at their approximate fair value of $0.1 million and $1.3 million, respectively, (Level2) as of* December 31, 2025.*See Note (13) - “Derivative Instruments and Hedging Activities” for activity and disclosure related to our foreign currency derivative contracts.

We didnot designate these contracts as hedges for accounting purposes.

Derivative instruments are classified as either assets or liabilities based on their individual fair values. The fair value of our derivative instruments was as follows:

Each of ourfive operating segments is led by senior management ultimately reporting to our Chief Executive Officer, the chief operating decision maker (CODM). Our operating segments comprise the structure used by our CODM to make key operating decisions and assess performance. Discrete financial information is available for each of the segments, and our CODM uses the results of each of the operating segments for resource allocation and performance evaluation. Our CODM evaluates the segments’ operating performance based on segment operating income. Segment operating income is defined as segment revenues less segment costs and expenses. The CODM primarily considers segment operating income for evaluating performance of each segment and making decisions about allocating capital and other resources to each segment.

The following tables provide a comparison of revenues, vessel operating profit, depreciation and amortization, additions to properties and equipment and assets by segment and in total for thethree andnine months ended* September 30, 2026and2025*. Vessel operating profit is calculated as vessel revenues less vessel operating costs, segment depreciation expenses, and segment general and administrative costs. Vessel revenues and operating costs relate to our owned and operated vessels while other operating revenues relate to the activities of our other miscellaneous marine-related businesses.

Pursuant to the SPA, we agreed to indemnify certain previous owners of the Wilson Companies in respect to the replacement of certain parent guarantees for the BNDES Vessel Construction Loans that would remain in place after the Closing Date of the Wilson Acquisition. Before the Closing Date, to support and backstop our obligation to indemnify these previous owners, we procured unsecured bank guarantees from DNB Bank ASAnot to exceed the amount of $170.5 million (Replacement LCs). Following the replacement of such parent guarantees for the BNDES Vessel Construction Loans, the Replacement LCs were terminated on* October 2, 2026*at a total cost of approximately $1.3 million.
