Indenture and the 2030 Notes

On July 7, 2025, Tidewater Inc., a Delaware corporation (the “Company”), certain of the Company’s subsidiaries (the “Guarantors”), and Wilmington Trust, National Association, as trustee (the “Trustee”), entered into an indenture (the “Indenture”), pursuant to which the Company issued $650,000,000 in aggregate principal amount of the Company’s 9.125% Senior Notes due 2030 (the “2030 Notes”). The 2030 Notes are unconditionally guaranteed on a senior unsecured basis by the Guarantors and will be unconditionally guaranteed on the same basis by certain of the Company’s future subsidiaries that guarantee certain indebtedness of the Company and the Guarantors, including the New Revolving Credit Facility (as defined below).

Interest and Maturity

The 2030 Notes mature on July 15, 2030. Interest on the 2030 Notes is payable semi-annually in arrears on each January 15 and July 15, commencing January 15, 2026, to holders of record on the January 1 and July 1 immediately preceding the related interest payment date, at a rate of 9.125% per annum.

Optional Redemption

At any time prior to July 15, 2027, the Company may, from time to time, redeem up to 40% of the aggregate principal amount of 2030 Notes, upon not less than 10 or more than 60 days’ notice, at a redemption price of 109.125% of the principal amount of the 2030 Notes redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date), in an amount not greater than the net cash proceeds of one or more qualified equity offerings by the Company, subject to certain requirements. In addition, prior to July 15, 2027, the Company may redeem the 2030 Notes, in whole at any time or in part from time to time, upon not less than 10 or more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the 2030 Notes redeemed, plus an applicable make-whole premium and accrued and unpaid interest, if any, to, but excluding, the redemption date.

At any time on or after July 15, 2027, the Company may redeem the 2030 Notes, in whole or in part at any time or from time to time, upon not less than 10 or more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, on the 2030 Notes redeemed to, but excluding, the applicable redemption date (subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date), if redeemed during the twelve-month period beginning on July 15 of the years indicated below:

Year	Redemption Price
2027		104.563	%
2028		102.281	%
2029 and thereafter		100.000	%

Change of Control

If a Change of Control Triggering Event (as defined in the Indenture) occurs, each holder of 2030 Notes may require the Company to purchase all or any part of that holder’s 2030 Notes for cash at a price equal to 101% of the principal amount of the 2030 Notes to be purchased, plus any accrued and unpaid interest thereon, if any, to, but excluding, the date on which the notes are purchased.

Certain Covenants

The Indenture contains covenants that, among other things and subject to certain exceptions, limit the Company’s ability and the ability of its restricted subsidiaries to: (i) incur, assume or guarantee additional indebtedness or issue certain preferred stock; (ii) create liens to secure indebtedness; (iii) pay distributions on equity interests, repurchase equity securities, make investments or redeem subordinated indebtedness; (iv) restrict distributions, loans or other asset transfers from the Company’s restricted subsidiaries to the Company; (v) consolidate with or merge with or into, or sell substantially all of the Company’s assets to, another person; (vi) sell or otherwise dispose of assets, including equity interests in subsidiaries; (vii) designate a subsidiary as an Unrestricted Subsidiary (as defined in the Indenture); and (viii) enter into transactions with affiliates.

Events of Default

The Indenture contains customary events of default, including, among other things, failure to make required payments, failure to comply with certain agreements or covenants, failure to pay or acceleration of certain other indebtedness, certain events of bankruptcy and insolvency, and failure to pay certain judgments. An event of default under the Indenture will allow either the Trustee or the holders of at least 25% in aggregate principal amount of the then-outstanding 2030 Notes to accelerate the amounts due under the 2030 Notes.

The foregoing description of the Indenture does not purport to be complete and is qualified in its entirety by reference to the full text of the Indenture and the form of 9.125% Senior Notes due 2030, which are filed with this Current Report on Form 8-K (this “Current Report”) as Exhibit 4.1 and Exhibit 4.2, respectively.

New Credit Agreement

On July 7, 2025, the Company and the Guarantors entered into a credit agreement with DNB Bank ASA, New York Branch, as facility agent and security trustee, and a syndicate of lenders (the “New Credit Agreement”) providing for a new $250 million senior secured revolving credit facility (the “New Revolving Credit Facility”). The New Credit Agreement will replace the Company’s existing $25 million super senior secured revolving credit facility provided by that certain Credit Facility Agreement, dated November 16, 2021, by and among the Company, DNB Bank ASA, New York Branch, as facility agent, Nordic Trustee AS, as security trustee, DNB Markets, Inc. as bookrunner and mandated lead arranger, and the lenders party thereto (the “Existing Credit Facility”), which has been terminated in connection with the financing transactions described in this Current Report. Borrowing availability under the New Revolving Credit Facility is subject to customary conditions precedent that the Company expects will be satisfied in the near term.

All obligations of the Company under the New Credit Agreement and certain swap obligations will be unconditionally guaranteed, on a joint and several basis, by the Company and certain of its current and future material U.S. subsidiaries. All such obligations, including the guarantees of the New Revolving Credit Facility, will be secured by senior priority liens on substantially all assets of the Company and the guarantors, subject to certain exceptions and limitations described in the New Credit Agreement.

Loans under the New Revolving Credit Facility will bear interest at a rate per annum equal to Term SOFR plus an applicable margin ranging from 250 to 350 basis points, depending on the Company’s net leverage ratio, in the case of SOFR loans and ABR plus an applicable margin ranging from 250 to 350 basis points, depending on the Company’s net leverage ratio in the case of an ABR advance.

The New Credit Agreement requires payment of customary quarterly commitment fees and letter of credit and fronting fees under the New Revolving Credit Facility.

Under certain circumstances, mandatory prepayments or commitment reductions will be required under the New Credit Agreement in connection with certain asset sales, asset swaps and events of loss that cause the collateral coverage ratio to drop below 5.00 to 1.00 (subject to reinvestment rights), unless the Company causes one or more additional vessels to become collateral vessels such that the Company’s collateral coverage ratio is at least 5.00 to 1.00. Available cash and cash equivalents in excess of $175 million, subject to certain exclusions, will be required to be applied monthly to prepay outstanding loans (without a commitment reduction). Additionally, the Company will not be permitted to make a new borrowing if such borrowing would result in the Company’s available cash and cash equivalents to exceed $175 million, subject to certain exclusions. Any loans under the New Revolving Credit Facility will be subject to voluntary prepayment, and the commitments thereunder subject to voluntary termination or reduction, by the Company at any time without premium or penalty, other than customary breakage costs.

The New Credit Agreement requires the Company and its restricted subsidiaries to comply with the following financial maintenance covenants:

as of the last day of each fiscal quarter, beginning with March 31, 2025, the ratio of the Company’s net interest-bearing debt to the Company’s consolidated EBITDA must be equal to or less than 3.00 to 1.00;

as of the last day of each fiscal quarter, beginning with March 31, 2025, the sum of (a) the amount available for drawing under the New Revolving Credit Facility plus (b) the aggregate amount of cash and cash equivalents of the Company and the guarantors must not be less than the greater of (i) $20 million and (ii) 10% of total net interest-bearing indebtedness of the Company and its restricted subsidiaries; and

subject to certain customary cure rights, the collateral maintenance ratio must at all times be 250% or more.

The New Credit Agreement contains affirmative and negative covenants, representations and warranties and events of default that the Company considers customary for facilities of this type.

Item 1.02
