CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Forward-looking statements provide our current expectations or forecasts of future events.

The words “anticipates,” “believe,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predicts,” “project,” “should,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.

These forward-looking statements are based on information available as of the date of this prospectus, and current expectations, forecasts and assumptions, and involve a number of judgments, risks and uncertainties. Accordingly, forward-looking statements should not be relied upon as representing the parties’ views as of any subsequent date, and the Company does not undertake any obligation to update forward-looking statements to reflect events or circumstances after the date they were made, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws. You should not place undue reliance on these forward-looking statements. As a result of a number of known and unknown risks and uncertainties, actual results or performance may be materially different from those expressed or implied by these forward-looking statements.

PROSPECTUS SUMMARY

Company Overview

We own and operate one of the largest integrated equipment dealership platforms in the Unites States (“U.S”). Through our branch network, we sell, rent, and provide parts and service support for several categories of specialized equipment, including lift trucks and aerial work platforms, cranes, earthmoving equipment and other Material Handling and Construction Equipment. We engage in five principal business activities in these equipment categories:

We have operated as an equipment dealership for over 35 years and have developed a branch network that includes 55 total locations in Michigan, Illinois, Indiana, Massachusetts, Maine, Connecticut, New Hampshire, Vermont, New York, Virginia, and Florida. We offer our customers a one-stop-shop for most of their equipment needs by providing sales, parts, service, and rental functions under one roof. More recently, with the acquisition of PeakLogix, we have entered the warehouse design, automated equipment installation and system integration sector, which we believe has natural synergies with our Material Handling business and positions us to take advantage of the macroeconomic trend in warehousing and logistics, and e-commerce.

Within our territories, we are the exclusive distributor of new equipment and replacement parts on behalf of our OEM partners. We enjoy long-standing relationships with leading Material Handling and Construction Equipment OEMs, including Hyster-Yale, Volvo, and JCB, among more than 30 others. We are consistently recognized by OEMs as a top dealership partner and have been identified as a nationally recognized Hyster-Yale dealer and multi-year recipient of the Volvo Dealer of the Year award.

We are committed to providing our customers with a best-in-class equipment dealership experience. Our customers are principally focused on equipment reliability and up-time, and our teams of skilled technicians and commitment to service are key to establishing and maintaining long-term customer relationships, representing a critical competitive advantage. Parts and service are also our most predictable and profitable businesses, with the dealership model structured to drive aftermarket parts and service revenue. Through our new and used equipment sales and our sale of rental fleet, we populate our exclusive territories with serviceable equipment. As the field population ages, we capitalize on aftermarket parts and service sales through the equipment maintenance cycle.

We have experienced significant organic and acquisition-led growth since 2008, completing over 20 acquisitions in that timeframe. We expect that acquisition activity to continue, as OEM partners support us as a consolidator by granting us new exclusive territories or by consenting to our acquisition of existing dealers.

Private Placements

The common stock registered for resale on this Prospectus was issued to the selling securityholders in a private placement in connection with the Howell Acquisition.  The shares were registered for resale on the Form S-1 pursuant to the provisions of the asset purchase agreement executed in connection with the Howell Acquisition.

RISK FACTORS

Investing in our securities involves risk. See the risk factors described in our most recent Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as applicable, and those contained in our other filings with the SEC that are incorporated by reference in this prospectus and any accompanying prospectus supplement. Before making an investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus and any accompanying prospectus supplement. These risks could materially adversely affect our business, financial condition or results of operations and the trading price of our securities to decline. You could lose all or part of your investment.

USE OF PROCEEDS

The selling stockholders will receive all of the net proceeds from the sale of the shares of common stock offered hereby. We will not receive any proceeds from this offering.

SELLING SECURITYHOLDERS

This prospectus also relates to the resale or distribution from time to time by the selling securityholders named in this prospectus or their permitted transferees of up to 507,143 shares of our common stock issued to the selling securityholders in connection with the consummation of the Howell Acquisition.

The term “selling securityholders” includes the securityholders listed in the table below and their permitted transferees.

The following table provides, as of the date of this prospectus, information regarding the beneficial ownership of our common stock of each selling securityholder, the number of shares of our common stock that may be sold by each selling securityholder under this prospectus and that each selling securityholder will beneficially own after this offering.

Because each selling securityholder may dispose of all, none or some portion of their securities, no estimate can be given as to the number of securities that will be beneficially owned by a selling securityholder upon termination of this offering. For purposes of the table below, however, we have assumed that after termination of this offering none of the securities covered by this prospectus will be beneficially owned by the selling securityholders and further assumed that the selling securityholders will not acquire beneficial ownership of any additional securities during the offering. In addition, the selling securityholders may have sold, transferred or otherwise disposed of, or may sell, transfer or otherwise dispose of, at any time and from time to time, our securities in transactions exempt from the registration requirements of the Securities Act after the date on which the information in the table is presented.

We may amend or supplement this prospectus from time to time in the future to update or change this selling securityholders list and the securities that may be resold.

Please see the section titled “Plan of Distribution” for further information regarding the stockholders’ method of distributing these shares.

Shares of common stock

PLAN OF DISTRIBUTION

T The selling securityholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of our common stock or interests in shares of our common stock received after the date of this prospectus from a selling securityholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of our common stock or interests in shares of our common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The selling securityholders may use any one or more of the following methods when disposing of shares or interests therein:

7

In addition, a selling securityholder that is an entity may elect to make an in-kind distribution of securities to its members, partners or stockholders pursuant to the registration statement of which this prospectus is a part by delivering a prospectus with a plan of distribution. Such members, partners or stockholders would thereby receive freely tradeable securities pursuant to the distribution through a registration statement. To the extent a distributee is an affiliate of ours (or to the extent otherwise required by law), we may file a prospectus supplement in order to permit the distributees to use the prospectus to resell the securities acquired in the distribution.

The selling securityholders may, from time to time, pledge or grant a security interest in some or all of the shares of our common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of our common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling securityholders to include the pledgee, transferee or other successors in interest as selling securityholders under this prospectus. The selling securityholders also may transfer the shares of our common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

In connection with the sale of our shares of our common stock or interests therein, the selling securityholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the shares of our common stock in the course of hedging the positions they assume. The selling securityholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling securityholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the selling securityholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. Each of the selling securityholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

The selling securityholders and any underwriters, broker-dealers or agents that participate in the sale of the common stock or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling securityholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, the shares of our common stock to be sold, the names of the selling securityholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the selling securityholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling securityholders and their affiliates. In addition, to the extent applicable we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling securityholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling securityholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify the selling securityholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

We have agreed with the selling securityholders to keep the registration statement of which this prospectus constitutes a part effective until such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with the registration statement or such securities have been withdrawn.
