Other Events

On May 23, 2017, GP Investments Acquisition Corp., a Cayman Islands exempted company limited by shares (the “Company”), held an extraordinary general meeting of shareholders (the “Extraordinary General Meeting”) to approve, among other things, the extension of the date by which the Company must (i) consummate a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (a “business combination”), (ii) cease its operations if it fails to complete such business combination, and (iii) redeem all of the Company’s ordinary shares included as part of the units sold in the Company’s initial public offering that was consummated on May 26, 2015, from May 26, 2017 to November 27, 2017 (the “Extension Amendment Proposal”).

On May 23, 2017, the shareholders of the Company approved, among other things, the Extension Amendment Proposal. In connection with the Extension Amendment Proposal, public shareholders had the right to elect to redeem their shares for a per-share price, payable in cash, based upon the aggregate amount then on deposit in the Company’s trust account, as described in the definitive proxy statement filed with the SEC on April 24, 2017 relating to the Company’s Extraordinary General Meeting (the “Definitive Proxy Statement”).

In connection with the Extension Amendment Proposal, public shareholders holding 1,552,724 ordinary shares validly elected to redeem their ordinary shares. As of May 23, 2017, the balance in the Company’s trust account, after deduction of the amount required to redeem the ordinary shares to be redeemed on May 25, 2017, is $157.8 million.

Forward Looking Statements

The Company believes that some of the information in this Form 8-K constitutes forward-looking statements. You can identify these statements by forward-looking words such as “will”, “expects” and “proposes” or similar words. You should read statements that contain these words carefully because they (a) discuss future expectations, (b) contain projections of future results of operations or financial condition, and (c) state other “forward-looking” information. The Company believes it is important to communicate its expectations to the Company’s shareholders. However, there may be events in the future that the Company is not able to predict accurately or over which the Company has no control. Risks, uncertainties and events may cause actual results to differ materially from the expectations described by the Company in such forward-looking statements. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this Form 8-K. All forward-looking statements included herein in this Form 8-K are expressly qualified in their entirety by the cautionary statements contained in this section. Except to the extent required by applicable laws and regulations, we undertake no obligation to update or revise these forward-looking statements, whether as a result of new information, future events or otherwise. The Company’s shareholders are also advised to read the Definitive Proxy Statement, and any other relevant materials filed with the Securities and Exchange Commission (the “SEC”), carefully in their entirety, once available, including the section included therein relating to forward-looking statements, before making any voting or investment decision with respect to the matters referred to in this Form 8-K.
