Item 1.01 Entry into a Material Definitive Agreement.

Agreement and Plan of Merger

On September 7, 2018, Industrea Acquisition Corp. (the “Company”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Concrete Pumping Holdings Acquisition Corp., a Delaware corporation and wholly owned subsidiary of the Company (“Newco”), Concrete Pumping Intermediate Acquisition Corp., a Delaware corporation and wholly owned subsidiary of Newco (“Concrete Parent”), Concrete Pumping Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of Concrete Parent (“Concrete Merger Sub”), Industrea Acquisition Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of Newco (“Industrea Merger Sub”), Concrete Pumping Holdings, Inc., a Delaware corporation (“CPH”), and PGP Investors, LLC, solely in its capacity as the initial Holder Representative thereunder (the “Holder Representative”), pursuant to which (a) Concrete Merger Sub will be merged with and into CPH, with CPH surviving the merger as a wholly owned indirect subsidiary of Newco (the “CPH Merger”), and (b) Industrea Merger Sub will be merged with and into the Company, with the Company surviving the merger as a wholly owned subsidiary of Newco (the “Industrea Merger”). The CPH Merger, the Industrea Merger and the other transactions contemplated in the Merger Agreement are referred to herein as the “Business Combination.”

Merger Consideration

Under the Merger Agreement and pursuant to the CPH Merger, Newco will acquire CPH for aggregate consideration of $610.0 million (subject to certain customary adjustments), payable in cash after taking into account (x) any shares of CPH capital stock that are contributed to Newco in exchange for shares of Newco’s common stock (“Newco common stock”) (valued at $10.20 per share) prior to the consummation of the CPH Merger and (y) any vested options to purchase shares of CPH common stock that are converted into vested options to purchase shares of Newco common stock immediately prior to the closing of the Business Combination. The cash portion of the consideration payable in the CPH Merger is expected to be between $446.9 million and $550.0 million, depending on the number of the Company’s public shares that are redeemed (“Redemptions”) in connection with the closing of the Business Combination (the “Closing”).

Under the Merger Agreement and pursuant to the Industrea Merger, all of the issued and outstanding shares of the Company’s common stock (“Industrea common stock”) will be exchanged on a one-for-one basis for shares of Newco common stock and all of the outstanding warrants to purchase Industrea common stock will be assumed by Newco and be exercisable for an equal number of shares of Newco common stock on the existing terms and conditions of such warrants.

Representations, Warranties and Covenants

The parties to the Merger Agreement have made customary representations, warranties and covenants in the Merger Agreement, including, among others, covenants with respect to the conduct of the Company and CPH during the period between execution of the Merger Agreement and the Closing.

Conditions to Closing

The Closing is subject to certain conditions, including, among others, (i) approval by the Company’s stockholders of the Merger Agreement and the Business Combination; (ii) delivery by CPH to the Company of a written consent of the stockholders of CPH approving and adopting the Merger Agreement and the CPH Merger within two (2) business days after the date of the Merger Agreement; and (iii) the expiration or termination of the applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. 

Termination

The Merger Agreement may be terminated under certain circumstances, including, among others: (i) by written consent of the Company and the Holder Representative; (ii) by the Company or CPH if the Closing has not occurred on or prior to the date that is 180 days after the execution of the Merger Agreement, unless the willful breach of such party seeking such termination is the primary reason for the Closing not occurring on or before such date; (iii) by CPH any time prior to the receipt of the approval of the Company’s stockholders of the Merger Agreement and the Business Combination, if the Company’s board of directors (x) failed to recommend to the Company’s stockholders that they approve the Merger Agreement and the Business Combination or failed to include such recommendation in the proxy statement/prospectus relating to the special meeting of the Company’s stockholders to be held to approve the Merger Agreement and the Business Combination (the “Special Meeting”), or (y) effected a change in such recommendation; or (iv) by CPH if the Company’s stockholders have not approved the Merger Agreement and the Business Combination at the Special Meeting or at any adjournment or postponement thereof, in each case at which a vote on such approval was taken.

Indemnification

Subject to the limitations set forth in the Merger Agreement, from and after the Closing Date, (i) the Company and its related parties will be indemnified from the amount and any interest accrued thereon held in escrow for purposes of indemnification, from and against any and all losses arising from certain matters, including, among others, (x) breaches of certain specified representations, warranties and covenants of CPH, (y) unpaid transaction expenses and funded debt of CPH, in each case, to the extent not actually included in the calculation of final merger consideration and (z) certain claims by pre-Closing holders of CPH securities, and (ii) the Company and its related parties will, jointly and severally, indemnify the CPH equityholders from and against all losses arising from breaches of certain specified representations, warranties and covenants of Industrea parties.

The foregoing description of the Merger Agreement and the Business Combination does not purport to be complete and is qualified in its entirety by the terms and conditions of the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 and is incorporated herein by reference. The Merger Agreement contains representations, warranties and covenants that the respective parties made to each other as of the date of such agreement or other specific dates. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract among the respective parties and are subject to important qualifications and limitations agreed to by the parties in connection with negotiating such agreement. The Merger Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company, CPH or any other party to the Merger Agreement. In particular, the representations, warranties, covenants and agreements contained in the Merger Agreement, which were made only for purposes of such agreement and as of specific dates, 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 and reports and documents filed with the U.S. Securities and Exchange Commission (the “SEC”). Investors should not rely on the representations, warranties, covenants and agreements, or any descriptions thereof, as characterizations of the actual state of facts or condition of any party to the Merger Agreement. In addition, the representations, warranties, covenants and agreements and other terms of the Merger Agreement may be subject to subsequent waiver or modification. Moreover, information concerning the subject matter of the representations and warranties and other terms may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.

In connection with the Merger Agreement, the Company and Newco entered into a subscription agreement (the “Argand Subscription Agreement”) with Argand Partners Fund, LP (the “Argand Investor”), an affiliate of the Company’s sponsor Industrea Alexandria LLC (the “Sponsor”), for the purpose of funding the Business Combination consideration and paying the costs and expenses incurred in connection therewith and offsetting potential redemptions of the Company’s public shares in connection with the Business Combination (“Redemptions”).

Forward-Looking Statements

This Current Report on Form 8-K includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995.

Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, the Company’s and CPH’s expectations with respect to future performance and anticipated financial impacts of the Business Combination, the satisfaction of the closing conditions to the Business Combination and the timing of the completion of the Business Combination. These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from the expected results. Most of these factors are outside the Company’s and CPH’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement or could otherwise cause the Business Combination to fail to close; (2) the outcome of any legal proceedings that may be instituted against the Company and CPH following the announcement of the Merger Agreement and the Business Combination; (3) the inability to complete the Business Combination, including due to failure to obtain approval of the stockholders of the Company or other conditions to closing in the Merger Agreement; (4) the receipt of an unsolicited offer from another party for an alternative business transaction that could interfere with the Business Combination; (5) the inability to obtain or maintain the listing of the shares of common stock of the post-acquisition company on The Nasdaq Stock Market following the Business Combination; (6) the risk that the Business Combination disrupts current plans and operations as a result of the announcement and consummation of the Business Combination; (7) the ability to recognize the anticipated benefits of the Business Combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably and retain its key employees; (8) costs related to the Business Combination; (9) changes in applicable laws or regulations; (10) the possibility that CPH or the combined company may be adversely affected by other economic, business, and/or competitive factors; and (11) other risks and uncertainties indicated from time to time in the proxy statement relating to the Business Combination, including those under “Risk Factors” therein, and in the Company’s other filings with the SEC. The Company cautions that the foregoing list of factors is not exclusive. The Company cautions readers not to place undue reliance upon any forward-looking statements, which speak only as of the date made. The Company does not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in its expectations or any change in events, conditions or circumstances on which any such statement is based.
