Item 1.01 Entry into a Material Definitive Agreement.

Agreement and Plan of Merger

On November 7, 2025, IES Holdings, Inc, a Delaware corporation (“IES”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Gulf Island Fabrication, Inc., a Louisiana corporation (“Gulf Island” or the “Company”), and IES Merger Sub, LLC, a Louisiana limited liability company and an indirect wholly owned subsidiary of IES (“Merger Sub”). The Merger Agreement provides that, among other things and on the terms and subject to the conditions of the Merger Agreement, (1) Merger Sub will merge with and into Gulf Island, with Gulf Island surviving the Merger as an indirect wholly owned subsidiary of IES (the “Merger”), and (2) at the effective time of the Merger (the “Effective Time”), each issued and outstanding share of Gulf Island’s common stock, no par value per share (the “Gulf Island Common Stock”), as of immediately prior to the Effective Time (other than certain excluded shares) will be converted into the right to receive $12.00 in cash, without interest, and subject to deduction for any required tax withholding (the “Merger Consideration”).

The Board of Directors of IES and the Board of Directors of Gulf Island (“Gulf Island Board”) have approved the Merger, Merger Agreement and the transactions contemplated thereby, and the Gulf Island Board has resolved to recommend that Gulf Island’s shareholders approve the Merger Agreement.

Treatment of Gulf Island Equity Awards

Gulf Island’s directors and executive officers hold outstanding equity-based awards consisting of both time-based and performance-based restricted stock units that represent the right to receive an equivalent number of shares of Gulf Island Common Stock (the “Gulf Island RSU Awards”). Under the terms of the Merger Agreement, each outstanding award of time-based restricted stock units granted under Gulf Island’s equity incentive plans shall, at the Effective Time, be converted into the right to receive upon vesting a cash payment in an amount equal to the product of (i) the number of shares of Gulf Island Common Stock subject to such Gulf Island RSU Award immediately prior to the Effective Time multiplied by (ii) $12.00, the Merger Consideration (each, a “Substitute Award”). Additionally, under the terms of the Merger Agreement, each outstanding performance-based Gulf Island RSU Award with a performance period that is incomplete (or that is complete but for which performance is not determinable ) as of the Effective Time shall be treated as if performance had been achieved at the target level (i.e., 100%), and shall be converted to a Substitute Award. Each Substitute Award shall remain subject to the original vesting terms and conditions as the underlying Gulf Island RSU Award, except as otherwise provided under the terms and conditions of the Merger Agreement or any employment agreement by and between the holder of a Substitute Award and the surviving corporation, and will pay out as follows:

•Non-Employee Directors’ Substitute Awards. The Gulf Island RSU Awards held by non-employee directors provide for the automatic acceleration of vesting upon a change of control if the director ceases to serve as a member of the Gulf Island Board as a result of the change of control. As such, the Substitute Awards held by non-employee directors will vest upon the Effective Time of the Merger and will be settled in accordance with the terms of the Merger Agreement; and

•Executive Officers’ and Other Employees’ Substitute Awards. The Gulf Island RSU Awards held by the Gulf Island’s executive officers and employees provide for acceleration of vesting in connection with certain terminations of employment following a change of control. Specifically, following the Effective Time, the Substitute Awards held by Gulf Island’s executive officers (except for Richard W. Heo, the Company’s Chief Executive Officer, and Westley S. Stockton, the Company’s Chief Financial Officer) and other employees will continue to vest according to the original vesting schedule under the underlying Gulf Island RSU Award, except that vesting will accelerate if the recipient’s employment is terminated (i) by the surviving corporation without cause prior to the vesting date, or (ii) by such recipient with good reason within one year following the Merger. The treatment of the Gulf Island RSU Awards held by Messrs. Heo and Stockton immediately prior to the Effective Time will be governed by the terms of the employment agreement that each has entered into with Gulf Island, which agreements provide that the Substitute Awards will continue to vest according to the original vesting schedule under the underlying Gulf Island RSU Award and any unvested Substitute Awards will vest at the end of the term of such employment agreement or earlier if the executive dies or his employment is terminated by the surviving corporation.

Conditions to the Merger

The completion of the Merger is subject to the satisfaction or waiver of certain customary mutual closing conditions, including, among other things, the approval of the Merger Agreement by at least a majority of the votes entitled to be cast on the matter by holders of the outstanding shares of Gulf Island Common Stock (the “Gulf Island Shareholder Approval”), the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (as amended, the “HSR Act”) and other regulatory approvals under applicable laws. The obligation of IES to consummate the Merger is also conditioned on no Company Material Adverse Effect (as defined in the Merger Agreement) having occurred since the execution of the Merger Agreement. The consummation of the Merger is not subject to any financing condition.

Termination

The Merger Agreement contains termination rights for each of IES and Gulf Island (1) if the consummation of the Merger does not occur on or before August 7, 2026 (the “End Date”), (2) if the Gulf Island Shareholder Approval is not obtained following a meeting of Gulf Island’s shareholders for purposes of obtaining such Gulf Island Shareholder Approval, (3) if the other party breaches its representations or warranties or fails to comply with its covenants or perform its other obligations contained in the Merger Agreement and such party does not timely cure, and (4) if an injunction has been issued and becomes final or law has been passed permanently enjoining or preventing the consummation of the transactions contemplated by the Merger Agreement. The Merger Agreement contains a termination right for Gulf Island in order for Gulf Island to substantially concurrently enter into a Company Acquisition Agreement (as defined in the Merger Agreement) providing for a Company Superior Offer (as defined in the Merger Agreement) prior to the receipt of the Gulf Island Shareholder Approval, subject to certain conditions. The Merger Agreement contains termination rights for IES (1) if, subject to certain conditions, the Gulf Island Board adversely changes its recommendation to Gulf Island’s shareholders with respect to the Merger, and (2) for a willful breach of Gulf Island’s covenants, including the non-solicitation covenant. IES and Gulf Island may also terminate the Merger Agreement by mutual written consent.

Gulf Island is required to pay IES a termination fee of approximately $7.6 million (the “Termination Fee”) in cash upon termination of the Merger Agreement under specified circumstances, including, among others, (1) termination by IES in the event that the Gulf Island Board adversely changes its recommendation to Gulf Island’s shareholders with respect to the Merger or (2) termination by Gulf Island to enter into a Company Acquisition Agreement (as defined in the Merger Agreement) providing for a Company Superior Offer (as defined in the Merger Agreement).

IES Voting

IES owns approximately 565,886 shares (or 3.5%) of the Gulf Island Common Stock. Pursuant to the Merger Agreement, IES has agreed to, and will cause its affiliates to, at the Special Meeting, and at every adjournment or postponement of the shareholder meeting (subject to the limits on the number of postponements and adjournments set forth in the Merger Agreement), and in any action by written consent of shareholders of Gulf Island, (1) appear (in person or by proxy) at each such meeting or otherwise cause all of the securities of Gulf Island that IES and its affiliates are entitled to vote to be counted as present thereat for purposes of calculating a quorum, and (2) cause all of the shares of Gulf Island Common Stock with respect to which IES and its affiliates have voting rights to be voted, and duly execute and deliver any written consent of shareholders of Gulf Island with respect to such shares of Gulf Island Common Stock, “FOR” (i) the proposal to approve the Merger Agreement and the Merger, (ii) any proposal to adjourn or postpone the Special Meeting to a later date if there are not sufficient votes for approval (subject to the limits on the number of postponements and adjournments set forth in the Merger Agreement), and (iii) each of the other actions contemplated by the Merger Agreement.

Other Terms of the Merger Agreement

The Merger Agreement contains customary representations and warranties of IES, Gulf Island, and Merger Sub, in each case generally subject to materiality qualifiers. Additionally, the Merger Agreement provides for customary pre-closing covenants of IES, Gulf Island, and Merger Sub, including covenants relating to Gulf Island conducting its and its subsidiaries’ business in the ordinary course, preserving its business organizations substantially intact, preserving existing relations with key business partners substantially intact and refraining from taking certain actions without IES’s consent, subject to certain exceptions.

The Merger Agreement generally restricts Gulf Island’s ability to directly or indirectly solicit Company Acquisition Proposals (as defined in the Merger Agreement) from third parties (including by furnishing non-public information), to participate in discussions or negotiations with third parties regarding any Company Acquisition Proposal or to enter into agreements providing for any Company Acquisition Proposal. Under certain circumstances, however, and in compliance with certain obligations contained in the Merger Agreement, Gulf Island is permitted to engage in negotiations with, and provide non-public information to, third parties that have made an unsolicited Company Acquisition Proposal on the Gulf Island Board’s determination in good faith, after consultation with financial advisors and outside legal counsel, that such Company Acquisition Proposal constitutes, or could reasonably be expected to result in, a Company Superior Offer (as defined in the Merger Agreement) and the failure to participate in such negotiations or to furnish such information would reasonably be likely to be inconsistent or deemed inconsistent with the Gulf Island Board’s fiduciary duties under applicable law.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is filed as Exhibit 2.1 hereto and is incorporated herein by reference.

The Merger Agreement and the above description have been included to provide investors and shareholders with information regarding its terms. They are not intended to provide any other factual information about Gulf Island, IES or the other parties thereto. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of the Merger Agreement as of the specific dates therein, were solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties thereto or any of their respective subsidiaries. Moreover, information concerning the subject matter of representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Gulf Island’s or IES’s public disclosures. Accordingly, the Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding IES, Gulf Island, and Merger Sub and the transactions contemplated by the Merger Agreement that will be contained in or attached as annexes to the proxy statement that Gulf Island will file in connection with the transactions contemplated by the Merger Agreement, as well as in other filings that Gulf Island or IES make with the U.S. Securities and Exchange Commission (the “SEC”).

Voting and Support Agreement

Concurrently with the execution of the Merger Agreement, certain of Gulf Island’s directors and executive officers and Piton Capital Partners LLC (“Piton Capital”), an affiliate of Robert Averick, a director of Gulf Island (collectively, the “Supporting Shareholders”), entered into a voting and support agreement (the “Voting Agreement”) with IES. Under the Voting Agreement, each of the Supporting Shareholders agreed, among other things, to vote the shares of Gulf Island Common Stock beneficially owned by the Supporting Shareholders in favor of the approval of the Merger Agreement and certain other matters, subject to the terms and conditions of such Voting Agreement. The Supporting Shareholders own approximately 20% of the Gulf Island Common Stock.

The Voting Agreement terminates upon the earliest of (i) the Effective Time of the Merger, (ii) termination of the Merger Agreement, (iii) a Company Change of Recommendation, or (iv) certain adverse amendments to the Merger Agreement. The foregoing description of the Voting Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Voting and Support Agreement, a copy of which is filed as Exhibit 10.1 hereto and is incorporated herein by reference.

Item 7.01 Regulation FD Disclosure.

On November 7, 2025, IES and Gulf Island issued a joint press release (the “Press Release”) announcing the entry into the Merger Agreement. A copy of the Press Release is furnished hereto as Exhibit 99.1.

Neither the information reported herein nor in the Press Release shall be deemed “filed” for purposes of Section 18 of the Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section unless the Company specifically states that the information is to be considered “filed” under the Exchange Act or incorporates it by reference into a filing under the Securities Act of 1933, as amended, or the Exchange Act.

Cautionary Statement on Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements. Forward-looking statements, within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995, are all statements other than statements of historical facts, such as projections or expectations relating to the consummation of the Merger and the realization of the anticipated benefits of the Merger. The words “anticipates,” “may,” “can,” “plans,” “expects,” “expected,” “projects,” “targets,” “intends,” “likely,” “will,” “should,” “to be,” “proposed,” “potential” and any similar expressions are intended to identify those assertions as forward-looking statements.

We caution readers that forward-looking statements are not guarantees of future performance and actual results may differ materially from those anticipated, projected or assumed in the forward-looking statements. Important factors that can cause our actual results to differ materially from those anticipated in the forward-looking statements include, but are not limited to: the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement or Company Change in Recommendation (as defined in the Merger Agreement); the inability to complete the Merger due to the failure to obtain the shareholder approval necessary for the Merger; the failure to obtain, delays in obtaining, or adverse conditions contained in any required regulatory or other approvals for consummation of the Merger or the failure to satisfy other conditions to completion of the Merger; the failure of the Merger to close for any other reason, including due to a Company Material Adverse Effect (as defined in the Merger Agreement); risks related to disruption of management’s attention from Gulf Island’s ongoing business operations due to the Merger; the outcome of any legal proceedings, regulatory proceedings or enforcement matters that may be instituted against IES, Gulf Island, or others relating to the Merger Agreement, the Merger or otherwise; the risk that the pendency of the Merger disrupts current plans and operations and the potential difficulties in employee retention as a result of the pendency of the Merger; the effect of the announcement of the Merger on IES’s and Gulf Island’s relationships with their contractual counterparties, including customers, operating results and business generally; the amount of the costs, fees, expenses and charges related to the Merger; and other factors described under the heading “Risk Factors” in Part I, Item 1A of each of IES’s and the Company’s Annual Reports on Form 10-K for the fiscal year ended December 31, 2024, as updated by subsequent filings with the SEC.

Additional factors or risks that we currently deem immaterial, that are not presently known to us or that arise in the future could also cause our actual results to differ materially from our expected results. Given these uncertainties, investors are cautioned that many of the assumptions upon which our forward-looking statements are based are likely to change after the date the forward-looking statements are made, which we cannot control. Further, we may make changes to our plans that could affect our results. We caution investors that we undertake no obligation to publicly update or revise any forward-looking statements, which speak only as of the date made, for any reason, whether as a result of new information, future events or developments, changed circumstances, or otherwise, and notwithstanding any changes in our assumptions, changes in plans, actual experience or other changes.
