A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.

In connection with the proposed Business Combination, Concrete Pumping Holdings Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of the Company (“Newco”) has filed a Registration Statement on Form S-4, which includes a preliminary proxy statement/prospectus of the Company. The Company’s stockholders and other interested persons are advised to read the preliminary proxy statement/prospectus and, when available, and the amendments thereto and the definitive proxy statement/prospectus and documents incorporated by reference therein filed in connection with the Business Combination, as these materials will contain important information about CPH, the Company and the Business Combination. When available, the definitive proxy statement/prospectus and other relevant materials for the Business Combination will be mailed to stockholders of the Company as of the Record Date. Stockholders will also be able to obtain copies of the preliminary proxy statement/prospectus, the definitive proxy statement/prospectus and other documents filed with the SEC that will be incorporated by reference therein, without charge, once available, at the SEC’s web site at www.sec.gov, or by directing a request to: Industrea Acquisition Corp., 28 West 44th Street, Suite 501, New York, NY 10036, Attention: Secretary, (212) 871-1107.

A list of the names of those directors and executive officers and a description of their interests in the Company is contained in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2017, which was filed with the SEC and is available free of charge at the SEC’s web site at www.sec.gov, or by directing a request to Industrea Acquisition Corp., 28 West 44th Street, Suite 501, New York, NY 10036, Attention: Secretary, (212) 871-1107.

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. The Company’s and CPH’s actual results may differ from their expectations, estimates and projections and consequently, you should not rely on these forward looking statements as predictions of future events. 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 Agreement and Plan of Merger entered into in connection with the Business Combination (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/prospectus 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 exhaustive. 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.

 No Offer or Solicitation

This Current Report on Form 8-K shall not constitute a solicitation of a proxy, consent or authorization with respect to any securities or in respect of the Business Combination. This Current Report on Form 8-K shall also not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any states or jurisdictions in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.
