On July 17, 2017, the Bankruptcy Court issued a written order (the “Confirmation Order”) confirming the Second Amended Joint Prepackaged Chapter 11 Plan of Reorganization of the Debtors, as modified by the Confirmation Order (the “Plan”).

On July 31, 2017 (the “Effective Date”), the Plan became effective in accordance with its terms and the Company and its subsidiaries emerged from the Bankruptcy Cases.

The descriptions of the Plan and the Confirmation Order in this Current Report on Form 8-K (this “Current Report”) do not purport to be complete and are qualified in their entirety by reference to the full text of the Plan and the Confirmation Order, which are filed as Exhibit 2.1 and Exhibit 99.1, respectively, to, and incorporated by reference into, this Current Report.

All capitalized terms used herein but not otherwise defined in this Current Report have the meanings set forth in the Plan.

Item 1.01. Entry into a Material Definitive Agreement.

Indenture

On the Effective Date, pursuant to the terms of the Plan, the Company entered into an indenture (the “Indenture”) by and among the Company, the wholly-owned subsidiaries named as guarantors therein (the “Guarantors”), and Wilmington Trust, National Association, as trustee and collateral agent (the “Trustee”), and issued $350 million aggregate principal amount of the Company’s new 8.00% Senior Secured Notes due 2022 (the “New Secured Notes”).

The New Secured Notes will mature on August 1, 2022. Interest on the New Secured Notes will accrue at a rate of 8.00% per annum payable quarterly in arrears on February 1, May 1, August 1, and November 1 of each year in cash, beginning November 1, 2017. The New Secured Notes are secured by substantially all of the assets of the Company and its Guarantors.

The New Secured Notes have minimum interest coverage requirements, minimum liquidity requirements, and other negative covenants as set forth in the Indenture. The Indenture contains certain customary events of default, including, among other things: (1) default in the payment of any interest when it becomes due and payable; (2) default in the payment of principal at maturity; (3) default in the performance or breach of any other covenant in the Indenture, which default continues uncured for a period of 30 days after (i) the Company’s receipt of written notice from the Trustee or (ii) the receipt by the Company and the Trustee of written notice from the holders of not less than 25% in principal amount of the New Secured Notes as provided in the Indenture; and (4) certain voluntary or involuntary events of bankruptcy, insolvency or reorganization of the Company.

Until terminated under the circumstances described below, the New Secured Notes and the guarantees by the Guarantors will be secured by the Collateral (as defined in the Indenture) pursuant to the terms of the Indenture and the related security documents. The Trustee’s liens upon the Collateral and the right of the holders of the New Secured Notes to the benefits and proceeds of the Trustee’s liens on the Collateral will terminate and be discharged: (i) upon satisfaction and discharge of the Indenture in accordance with the terms thereof; (ii) upon payment in full and discharge of all of the New Secured Notes outstanding under the Indenture and all other

1

obligations under the Indenture that are outstanding, due and payable under the Indenture at the time the New Secured Notes are paid in full and discharged (other than contingent indemnity obligations for which no claim has been made); (iii) as to any Collateral of the Company or the Guarantors that is sold, transferred or otherwise disposed of by the Company or the Guarantors in a transaction or other circumstance that complies with the terms of the Indenture, at the time of such sale, transfer or other disposition; (iv) in whole or in part, with the consent of the holders of the New Secured Notes of the requisite aggregate principal amount of New Secured Notes in accordance with the Indenture; or (v) with respect to the assets of the Guarantors, at the time that the Guarantors are released from their guarantees in accordance with the terms of the Indenture.

The foregoing description of the Indenture and the New Secured Notes does not purport to be complete and is qualified in its entirety by reference to the full text of the Indenture, which is filed as Exhibit 4.1 to, and is incorporated by reference into, this Current Report, and which includes the form of New Secured Notes.

Creditor Warrant Agreement

On the Effective Date, by operation of the Plan as confirmed by order of the Bankruptcy Court, and in such amounts and subject to such considerations as are discussed below, the Company entered into a warrant agreement (the “Creditor Warrant Agreement”) with Computershare Inc. and Computershare Trust Company, N.A. (together, the “Warrant Agent”), pursuant to which the Company issued, or caused to be reserved for issuance, warrants (the “New Creditor Warrants” and the holders thereof, the “New Creditor Warrant Holders”) to Non-U.S. Citizens who were holders of the Company’s unsecured notes, the lenders under the existing credit agreement, and the lessor parties to certain sale leaseback agreements (together, the “General Unsecured Creditors” and their claims, the “General Unsecured Claims”) on the Distribution Record Date (as defined in the Plan).

Subject to certain restrictions as described in greater detail below, each New Creditor Warrant is immediately exercisable for one share of the Company’s common stock, par value $0.001 (the “New Common Stock”) upon payment of an exercise price equal to the par value of the Company’s New Common Stock.

A total of 7,684,453 New Creditor Warrants were issued on the Effective Date to certain holders of allowed General Unsecured Claims who are Non-U.S. Citizens in lieu of an equal number of shares of New Common Stock, in order to ensure that, as required by the Plan, the aggregate percentage of the outstanding New Common Stock owned by Non-U.S. Citizens on the Effective Date was no more than 22%.

Under applicable statutes and regulations commonly referred to as the Jones Act, any corporation that engages in U.S. coastwise trade must be a U.S. Citizen within the meaning of that law, which requires, among other things, that the aggregate ownership of common stock by Non-U.S. Citizens within the meaning of the Jones Act be not more than 25% of its outstanding common stock. To ensure compliance with the Jones Act, and given the complete recapitalization of the Company through the bankruptcy, the Plan established a safety margin with respect to ownership by Non-U.S. Citizens, requiring that, on the date that the Company emerges from bankruptcy, not more than 22% of the outstanding New Common Stock will be held by Non-U.S. Citizens. After emergence, the Certificate of Incorporation (as defined and described under Item 5.03) limits ownership by Non-U.S. Citizens in the aggregate to no more than 24% of the Company’s outstanding New Common Stock.

The New Creditor Warrants have a 25-year term and are immediately exercisable at a nominal exercise price (par value of $0.001 per share) for shares of New Common Stock on a one-for-one basis, subject to restrictions contained in the Creditor Warrant Agreement and the Certificate of Incorporation limiting ownership by Non-U.S.

2

Citizens to 24%, as described above. Tidewater will establish, as permitted under its Certificate of Incorporation and through the Depositary Trust Company, appropriate measures to ensure compliance with these ownership limitations.

The New Creditor Warrants will not grant New Creditor Warrant Holders any voting or control rights or dividend rights, or contain any negative covenants restricting the operation of the Company’s business.

Termination. All unexercised New Creditor Warrants will expire, and the rights of the New Creditor Warrant Holders to purchase shares of New Common Stock will terminate on the first to occur of (i) the close of business on July 31, 2042 (the “NCW Expiration Date”) or (ii) upon settlement of all New Creditor Warrants validly exercised or converted prior to the NCW Expiration Date and, if exercised or converted under the terms of the Creditor Warrant Agreement by purchasing one share of New Common Stock at the exercise price, for which the exercise price was timely paid. However, the Creditor Warrant Agreement will terminate on any earlier date when all New Creditor Warrants have been exercised, converted or cancelled, provided that the responsibilities of the Warrant Agent will survive.

Adjustments. The number of shares of New Common Stock for which a New Creditor Warrant is exercisable, and the exercise price per share of such New Creditor Warrant are subject to adjustment from time to time upon the occurrence of certain events, including, among other things: (i) the issuance of shares of New Common Stock as a dividend or distribution to all holders of shares of New Common Stock, or a subdivision, combination, or other reclassification of the outstanding shares of New Common Stock into a greater or smaller number of shares of New Common Stock; (ii) the issuance as a dividend or distribution to all holders of shares of New Common Stock of evidences of indebtedness or other assets; and (iii) the merger, consolidation, recapitalization, reclassification, reorganization or business combination by the Company with another person.

Third-Party Mergers or Consolidations. In the event of a merger or consolidation where (i) the acquirer is not an affiliate of the Company, and (ii) all of the equity held by equity holders of the Company outstanding immediately prior thereto is extinguished or replaced by equity in a different entity, holders of New Creditor Warrants will be solely entitled to receive the consideration per New Creditor Warrant that is payable per share of New Common Stock, less the applicable exercise price of the New Creditor Warrant, which consideration shall be paid in the same form and in the same proportion as is payable to holders of New Common Stock. However, if the consideration is payable solely in cash, the New Creditor Warrants will be extinguished and the New Creditor Warrant Holders will be entitled to receive a cash payment for each New Creditor Warrant held equal to the difference between the per-share cash consideration and the nominal exercise price per share.

Reorganization Event. Upon the occurrence of a merger, consolidation, recapitalization, reclassification, reorganization or business combination by the Company with another person, each holder of New Creditor Warrants will have the right to receive, upon exercise of a New Creditor Warrant, the amount of securities, cash or other property that a holder of one share of New Common Stock would have owned or been entitled to receive in connection with such transaction.

Cashless Exercise. The New Creditor Warrants will permit a New Creditor Warrant Holder to elect to exercise the New Creditor Warrant such that no payment of cash will be required in connection with such exercise. If cashless exercise is elected, the Company shall deliver, without any cash payment therefor, a reduced number of shares of New Common Stock equal to the value (as of the exercise date for such New Creditor Warrant) of the aggregate exercise price which would otherwise be payable in cash for all of the shares of New Common Stock for which such New Creditor Warrants are being exercised, divided by the market price of a share of New Common Stock determined as of the business day immediately preceding the day the warrant exercise notice is delivered to the Warrant Agent.

This summary is qualified in its entirety by reference to the full text of the Creditor Warrant Agreement, which is filed as Exhibit 10.1 to, and incorporated by reference into, this Current Report.

Series A and Series B Warrant Agreement

On the Effective Date, by operation of the Plan and the Confirmation Order, the Company entered into a warrant agreement (the “Equity Warrant Agreement”) with the Warrant Agent, pursuant to which the Company issued two series of warrants (the “Series A Warrants” and the “Series B Warrants” and together, the “Equity Warrants,” and the holders thereof, the “Equity Warrant Holders”), on a pro rata basis to all pre-emergence holders of the Company’s common stock (the “Old Common Stock”).

Each Equity Warrant represents the right to purchase one share of New Common Stock at the applicable exercise price, subject to adjustment as provided in the Equity Warrant Agreement. On the Effective Date, the Company issued (i) Series A Warrants to purchase an aggregate of 2,432,432 shares of New Common Stock, with an exercise price of $57.06 per share and (ii) Series B Warrants to purchase an aggregate of 2,629,657 shares of New Common Stock, with an exercise price of $62.28 per share. Each series of warrants issued under the Equity Warrant Agreement has a six-year term.

Similar to the New Creditor Warrants, the Equity Warrants do not grant the Equity Warrant Holder any voting or control rights or dividend rights, or contain any negative covenants restricting the operation of the Company’s business. In addition, exercise of the Equity Warrants will be subject to the restrictions in the Certificate of Incorporation, which limit the exercise of such warrants where such exercise would cause the total number of shares held by Non-U.S. Citizens to exceed 24% of the Company’s outstanding New Common Stock.

Termination. All unexercised Equity Warrants will expire, and the rights of the Equity Warrant Holders to purchase shares of New Common Stock will terminate, on the first to occur of (i) the close of business on July 31, 2023 (the “EW Expiration Date”) or (ii) upon settlement of all Equity Warrants validly exercised prior to the EW Expiration Date and, if exercised under the terms of the Equity Warrant Agreement by purchasing one share of New Common Stock at the applicable exercise price, for which the exercise price was timely paid. Notwithstanding, the Equity Warrant Agreement will terminate on any earlier date when all Equity Warrants have been exercised, redeemed or cancelled, provided that the responsibilities of the Warrant Agent will survive.

Conversion to Jones Act Warrant. If, at any time during the 180-day period ending on the expiration of the Equity Warrants, the exercise of the Equity Warrants would be prohibited because of the Jones Act limitations on ownership by Non-U.S. Citizens, an Equity Warrant Holder that is a Non-U.S. Citizen and has exercised such warrant (including the payment of the exercise price) will receive from the Company, in lieu of shares of New Common Stock, an equivalent number of warrants substantially similar to the New Creditor Warrant (the “Jones Act Warrant”). These Jones Act Warrants, like the New Creditor Warrants, will be exercisable at a price of $0.001 per share and will have a term that expires on July 31, 2042. The Jones Act Warrants will be issued pursuant to a Jones Act Warrant Agreement that the Company and the Warrant Agent will enter into upon the Company’s first issuance of Jones Act Warrants.

Adjustments. The number of shares of New Common Stock for which an Equity Warrant is exercisable, and the exercise price per share of such Equity Warrant are subject to adjustment from time to time upon the occurrence of certain events, including, among other things: (i) the issuance of shares of New Common Stock as a dividend or distribution to all holders of shares of New Common Stock, or a subdivision, combination, or other reclassification of the outstanding shares of New Common Stock into a greater or smaller number of shares of New Common Stock; (ii) the issuance as a dividend or distribution

4

to all holders of shares of New Common Stock of evidences of indebtedness or assets (excluding cash distributions of dividends from earnings); and (iii) the payment in respect of a tender offer or exchange offer by the Company for shares of New Common Stock, where the exercise price or warrant shares issuable would result in an increase or decrease of at least one percent, provided, that any adjustments which are not required to be made are required to be carried forward and taken into account in any subsequent adjustments.

Third-Party Mergers or Consolidations. In the event of a merger or consolidation of the Company in which stock or non-cash consideration of the acquiring entity is more than 50% of the merger consideration, the Equity Warrants will remain outstanding, with the Equity Warrant Holders having the right thereafter to exercise the Equity Warrants for the duration of their term to acquire the merger consideration into which a share of New Common Stock was converted in the transaction. However, in the event of a merger or consolidation occurring within 18 months after the date of issuance of the Equity Warrants where 50% or more of the consideration is to be paid in cash, the Equity Warrants will be cancelled and such Equity Warrant Holders shall be paid out at their Black-Scholes value, using such inputs as are set forth in the Equity Warrant Agreement, even if the exercise price of the Equity Warrant is less than the per-share merger consideration.

Reorganization Event. Upon the occurrence of a Reorganization Event (as defined in the Equity Warrant Agreement), each holder of Equity Warrants will have the right to receive, upon exercise of an Equity Warrant (including the payment of the exercise price), the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of one share of New Common Stock would have owned or been entitled to receive in connection with such Reorganization Event.

Cashless Exercise. The Equity Warrants will permit an Equity Warrant Holder to elect to exercise the Equity Warrant such that no payment of cash will be required in connection with such exercise. If a cashless exercise is elected, the Company will deliver, without any cash payment therefor, a reduced number of shares of New Common Stock equal to the value (as of the exercise date for such Equity Warrant) of the aggregate exercise price which would otherwise be payable in cash for all of the shares of New Common Stock for which such Equity Warrants are being exercised, divided by the market price of a share of New Common Stock determined as of the business day immediately preceding the day the warrant exercise notice is delivered to the Warrant Agent.

This summary is qualified in its entirety by reference to the full text of the Equity Warrant Agreement, which is filed as Exhibit 10.2 to, and incorporated by reference into, this Current Report.

10

Provisions of Tidewater’s Certificate of Incorporation and Bylaws

Capital Stock. The Company’s authorized capital stock consists of 128,000,000 shares, which includes 125,000,000 shares of New Common Stock, par value $0.001, and 3,000,000 shares of preferred stock, without par value.

Dividends. Subject to the rights granted to any holders of the preferred stock, holders of the New Common Stock will be entitled to dividends, if any, in the amounts and at the times declared by the Company’s Board in its discretion out of any assets or funds of the Company legally available for the payment of dividends.

Voting. Each holder of shares of the New Common Stock is entitled to one vote for each share of the New Common Stock on all matters presented to the stockholders of the Company, including the election of directors. Each director will be elected by a majority of the votes cast with respect to that director’s election (i.e. the number of votes cast “for” a director exceeds the votes cast “against” the director), unless the number of nominees for director exceeds the number of directors to be elected, in which case, the directors will be elected by a plurality of the shares represented in person or by proxy and entitled to vote on the election of directors.

Written Consent of Stockholders. The Company’s Certificate of Incorporation provides that any action required or permitted to be taken by the stockholders must be taken at a duly called meeting of stockholders and not by written consent; however, this provision may be amended by the vote of 80% of the stockholders.

Amendment of the Bylaws. Under Delaware law, the power to adopt, amend or repeal bylaws is conferred upon the stockholders. A corporation may, however, in its certificate of incorporation also confer upon the board of directors the power to adopt, amend or repeal its bylaws. The Certificate of Incorporation and Bylaws grant the Board or the stockholders the power to adopt, amend and repeal the Bylaws on the affirmative vote of a majority of the directors then in office or of the shareholders owning a majority of the Company’s shares entitled to vote on the matter.

Special Meetings of Stockholders. The Bylaws preclude the ability of the stockholders to call special meetings of stockholders.

Other Limitations on Stockholder Actions. Advance notice is required for stockholders to nominate directors or to submit proposals for consideration at meetings of stockholders, which to be timely, such notice is required no sooner than 120 days and no later than 90 days before the meeting. The Bylaws provide detailed procedures for the nomination of directors and the conduct of meetings.

Record Date. The record date to determine who is entitled to notice of and to participate in a meeting will be no more than 60 and no less than 10 days before a meeting of stockholders. The Bylaws provide for a dual record date, in which the Board may establish a separate voting record date to determine the shareholders actually entitled to vote.

Board of Directors. The Board of Directors will consist of five or more members. The terms of the directors will run until a successor is duly elected and qualified or the death, resignation, disqualification or removal of the director. At each annual meeting of stockholders, all director seats are up for election. Directors are elected in an uncontested election by a majority of the votes cast and in a contested election by a plurality of the votes cast. When there is a contested election or a failed election, which does not bring the sufficient amount of votes, the director must tender his or her resignation, and the Board will determine whether or not to accept such resignation. Directors may be elected without a written ballot.

11

The Bylaws provide that any action required or permitted to be taken by the Board at a duly called meeting may be taken by the unanimous written consent of the Board.

Limitation of Liability and Indemnification of Officers and Directors. The Certificate of Incorporation provides that no officer or director shall be personally liable to the Company or the stockholders for monetary damages for breach of fiduciary duty as an officer or director to the fullest extent permitted by the DGCL. The Certificate of Incorporation provides for mandatory indemnification of the Company’s officers and directors and requires the mandatory advancement of expenses and coverage of amounts paid in settlement without the approval of the Company. The officers and directors have the right to sue if the Company does not pay upon a written demand within 30 days, but which may be extended up to an additional 30 days.

Business Combination Under Delaware Law. The Company is subject to the provisions of Section 203 of the DGCL and has voluntarily elected to be governed by Section 203 in the Certificate of Incorporation, except for the provisions of Section 203(b)(4). In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner.

Section 203 defines a “business combination” as a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholders. Section 203 defines an “interested stockholder” as a person who, together with affiliates and associates, owns, or, in some cases, within three years prior, did own, 15% or more of the corporation’s voting stock. Under Section 203, a business combination between the Company and an interested stockholder is prohibited unless:

This provision has an anti-takeover effect with respect to transactions not approved in advance by the Board, including discouraging takeover attempts that might result in a premium over the market price for the shares of the Company’s New Common Stock. With approval of the stockholders, the Company could amend the Certificate of Incorporation in the future to elect not to be governed by the anti-takeover law. This election would be effective 12 months after the adoption of the amendment and would not apply to any business combination between the Company and any person who became an interested stockholder on or before the adoption of the amendment. By “opting-in” to Section 203, the provisions will apply to the Company regardless of whether the Company is no longer listed on a National Securities Exchange or falls below 2,000 record holders under Section 203(b)(4).

Exclusive Forum. The Certificate of Incorporation provides that, unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of

12

Chancery shall not have jurisdiction, another state court located within the state of Delaware, or if no such state court shall have jurisdiction, the federal district court for the District of Delaware) will be, to the fullest extent permitted by law, the exclusive forum for (i) any derivative action or proceeding brought on the Company’s behalf, (ii) any action asserting a breach of fiduciary duty, (iii) any action asserting a claim arising pursuant to the DGCL, the Certificate of Incorporation or the Bylaws, or (iv) any action asserting a claim against the Company or any director or officer or other employee of the Company that is governed by the internal affairs doctrine. Any person or entity purchasing or otherwise holding any interest in shares of capital stock of the Company will be deemed to have notice of and consented to the foregoing forum selection provisions.

Limitations on Ownership by Non-U.S. Citizens. To ensure the continuing ability of U.S. flag vessels owned by the Company’s subsidiaries to be eligible to engage in U.S. coastwise trade, the Company’s Certificate of Incorporation and Bylaws include provisions restricting ownership by Non-U.S. Citizens of the Company’s capital stock. The Jones Act requires any corporation that engages in U.S. coastwise trade be a U.S. Citizen within the meaning of that law, which requires, among other things, that the aggregate ownership of common stock by Non-U.S. Citizens within the meaning of the Jones Act be not more than 25% of its outstanding common stock. The Company’s Certificate of Incorporation and Bylaws contain restrictions and protections designed to ensure the Company’s U.S. flag vessels continue to be eligible to engage in coastwise trade under the Jones Act. These restrictions and protections prohibit the acquisition of shares or exercise of warrants where such acquisition or exercise would cause the aggregate number of shares held by Non-U.S. Citizens to exceed 24%. These restrictions and protections further provide the Board authority to redeem any share of common stock that is owned by Non-U.S. Citizens that would result in ownership by Non-U.S. Citizens in the aggregate in excess of 24%.
