ORGANIZATION AND BASIS OF PRESENTATION

ORGANIZATION AND BASIS OF PRESENTATION

Organization

Rattler Midstream LP (the “Partnership”) is a publicly traded Delaware limited partnership, the common units of which are listed on the Nasdaq Global Select Market under the symbol “RTLR”. The Partnership was formed on July 27, 2018 by Diamondback Energy, Inc. (“Diamondback”) to, among other things, own, operate, develop and acquire midstream and energy-related infrastructure assets in the Midland and Delaware Basins of the Permian Basin. Unless the context requires otherwise, references to “the Partnership” are intended to mean the business and operations of the Partnership and its consolidated subsidiaries and, prior to May 28, 2019 for accounting purposes, the “Predecessor”.

The Predecessor’s assets, contributed from Diamondback, included (i) crude oil and natural gas gathering and transportation systems, (ii) produced water gathering and disposal systems, (iii) water sourcing and distribution systems and (iv) certain real property and related assets. All of the Partnership’s businesses are located or operate in the Permian Basin in West Texas.

On August 7, 2018, a Registration Statement on Form S-1 was filed with the SEC relating to the proposed underwritten initial public offering (the “IPO”) of common units of the Partnership. Prior to the completion of the IPO, the Predecessor was a wholly owned subsidiary of Diamondback.

Prior to the closing on May 28, 2019 of the IPO, Diamondback owned all of the general and limited partner interests in the Partnership. In connection with the IPO, the Partnership (i) issued 43,700,000 common units to the public at a price of $17.50 per common unit, representing a 29% voting limited partner interest in the Partnership, for net proceeds of approximately $719.4 million, (ii) issued 107,815,152 Class B units representing an aggregate 71% voting limited partner interest in the Partnership, in exchange for a $1.0 million cash contribution from Diamondback, (iii) issued a general partner interest in the Partnership to Rattler Midstream GP LLC (the “General Partner”) in exchange for a $1.0 million cash contribution from the General Partner and (iv) caused Rattler Midstream Operating LLC (the “Operating Company”) to make a distribution of approximately $726.5 million to Diamondback. Diamondback, as the holder of the Class B units, and the General Partner, as the holder of the general partner interest, are entitled to receive cash preferred distributions equal to 8% per annum on the outstanding amount of their respective $1.0 million capital contributions, payable quarterly.

As of December 31, 2020, the General Partner held a 100% general partner interest in the Partnership. Diamondback owns all of the Partnership’s 107,815,152 Class B units that provide a 72% voting interest. Diamondback owns and controls the General Partner.

As of December 31, 2020, the Partnership owned a 28% controlling membership interest in the Operating Company and Diamondback owned, through its ownership of the Operating Company units, a 72% economic, non-voting interest in the Operating Company. However, as required by GAAP, the Partnership consolidates 100% of the assets and operations of the Operating Company in its financial statements and reflects a non-controlling interest to Diamondback. In addition to the Operating Company, other consolidated subsidiaries of the Partnership include Tall City Towers LLC (“Tall Towers”), Rattler Ajax Processing LLC and Rattler OMOG LLC.

The Partnership also owns indirect interests in Amarillo Rattler, LLC; OMOG JV LLC (“OMOG”); EPIC Crude Holdings, LP (“EPIC”); EPIC Crude Holdings GP, LLC; Wink to Webster Pipeline LLC (“Wink to Webster”); and Gray Oak Pipeline, LLC (“Gray Oak”), which are accounted for as equity method investments as discussed further in Note 8—Equity Method Investments.

Basis of Presentation

Prior to May 28, 2019, the Partnership’s services were performed by the Predecessor. The consolidated financial statements include the results of the Predecessor for the periods presented prior to the closing of the IPO on May 28, 2019. The Predecessor financial statements have been prepared from the separate records maintained by the Partnership and may not necessarily be indicative of the actual results of operations that might have occurred if the Predecessor had been operated separately during the periods reported.

The consolidated results of operations following the completion of the IPO are presented together with the results of operations pertaining to the Predecessor. The assets of the Predecessor consist of produced water disposal wells and related

gathering systems, office buildings, surface land and an oil gathering system and asset retirement obligations related to these assets, which were contributed effective January 1, 2019. See Note 4—Acquisitions. The capital contribution of the net proceeds from the IPO to the Operating Company in exchange for 29% of the limited liability company units of the Operating Company was accounted for as a combination of entities under common control, with assets and liabilities transferred at their carrying amounts in a manner similar to a pooling of interests. The Partnership did not own any assets prior to May 28, 2019, the date of the equity contribution agreement by and between the Partnership and the Predecessor. Prior to the IPO, the Predecessor was a wholly owned subsidiary of Diamondback.

For periods prior to May 28, 2019, the accompanying consolidated financial statements and related notes thereto represent the financial position, results of operations, cash flows and changes in members’ equity of the Predecessor and, for periods on and after May 28, 2019, the accompanying consolidated financial statements and related notes thereto represent the financial position, results of operations, cash flows and changes in unitholders’ equity of the Partnership and its partially owned subsidiary, the Operating Company.

The Partnership’s operations are reported in two operating business segments: (i) midstream services and (ii) real estate operations.

The consolidated financial statements include the accounts of the Partnership and its subsidiaries after all significant intercompany balances and transactions have been eliminated upon consolidation.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period financial statement presentation. These reclassifications had no effect on the previously reported total assets, total liabilities, unitholders’ equity, results of operations or cash flows.
