1. Organization and Background of Business

Description of Business

We manufacture and provide patented proppant management systems that unload, store and deliver proppant at oil and natural gas well sites. The systems are designed to address the challenges associated with transferring large quantities of proppant to the well site, including the cost and management of last mile logistics.

The systems are deployed in many of the most active oil and natural gas basins in the U.S., including the Permian Basin, the Eagle Ford Shale, the SCOOP/STACK Formations and the Haynesville Shale.

We are also developing the first independent, unit-train capable, high speed transload facility in Oklahoma. We expect construction to be fully completed in August 2018. In July 2017, we entered into a seven-year contract with a leading STACK exploration and production company to provide proppant transloading service at the facility.

Initial Public Offering

Solaris Oilfield Infrastructure, Inc. (“Solaris” or the “Company”) was incorporated on February 2, 2017 as a Delaware corporation.

Solaris was formed for the purpose of completing an initial public offering of equity (the “IPO” or the “Offering”) and related transactions in order to carry on the business of Solaris Oilfield Infrastructure, LLC and its subsidiaries (“Solaris LLC”). On May 11, 2017, in connection with the closing of the offering, Solaris became a holding company whose sole material asset consists of units in Solaris LLC (“Solaris LLC Units”). Solaris became the managing member of Solaris LLC and is responsible for all operational, management and administrative decisions relating to Solaris LLC’s business.

On May 17, 2017, Solaris completed the Offering of 10,100,000 shares of the Class A common stock, par value $0.01 per share (“Class A Common Stock”), at a price to the public of $12.00 per share ($11.28 net of underwriting discounts and commissions). After deducting underwriting discounts and commissions payable by Solaris, Solaris received net proceeds of approximately $113.9 million. After deducting offering expenses of approximately $2.8 million, Solaris received approximately $111.1 million. Solaris contributed all of the net proceeds of the IPO to Solaris LLC in exchange for Solaris LLC Units. Solaris LLC used the net proceeds (i) to fully repay borrowings under its Credit Facility (as defined below) of $5.5 million, (ii) to pay approximately $3.1 million in cash bonuses to certain employees and consultants and (iii) to distribute approximately $25.8 million to its existing members (the “Original Investors”) as part of the corporate reorganization undertaken in connection with the IPO. Solaris LLC has used a portion of the proceeds and intends to continue to use the remaining proceeds for general corporate purposes, including funding the remainder of its 2017 capital program.

As the sole managing member of Solaris LLC, Solaris operates and controls all of the business and affairs of Solaris LLC, and through Solaris LLC and its subsidiaries, conducts its business. As a result, Solaris consolidates the financial results of Solaris LLC and its subsidiaries and reports non-controlling interest related to the portion of Solaris LLC Units not owned by Solaris, which will reduce net income (loss) attributable to the holders of Solaris’ Class A Common Stock. As of September 30, 2017, Solaris owned 25.9% of Solaris LLC, including unvested restricted stock.

Reorganization Transactions

In connection with the IPO, we completed a series of reorganization transactions on May 17, 2017 (the “Reorganization Transactions”), including:

Solaris LLC’s limited liability company agreement was amended and restated to, among other things, appoint Solaris as sole managing member, and all of the membership interests in Solaris LLC held by the Original Investors were converted into (i) a single class of Solaris LLC Units, representing in the aggregate 32,365,823 Solaris LLC Units and (ii) the right to receive the distributions of cash and shares of Solaris’ Class B common stock (“Class B Common Stock”) described in clauses (c) and (d) below;

Solaris issued and contributed 32,365,823 shares of its Class B Common Stock and all of the net proceeds of the IPO to Solaris LLC in exchange for a number of Solaris LLC Units equal to the number of shares of Class A Common Stock issued in the IPO;

Solaris LLC used a portion of the proceeds from the IPO to distribute to the Original Investors, on a pro rata basis, an aggregate amount of cash equal to 2,288,800 times the initial public offering price per share of Class A Common Stock after underwriting discounts and commissions; and

Solaris LLC distributed to each of the Original Investor one share of Class B Common Stock for each Solaris LLC Unit such Original Investor held.
