"Rattler closed the year on a high note, with a strong operational quarter in terms of volumes, operating expense control and Free Cash Flow. In particular, the free cash flow of $54 million in the fourth quarter and $216 million for full year 2021 highlights the cash generation potential of the operated business before taking into account the return of capital from the majority of Rattler's equity method joint ventures. Underpinned by contracts extending through 2034 and with unparalleled visibility into the development plan and reserves of its primary customer, Diamondback, Rattler's operated gathering business has been resilient, growing free cash flow even though Diamondback's oil production has stayed flat over the same time period," stated Travis Stice, Chief Executive Officer of Rattler's general partner.

Mr. Stice continued, "Looking forward to 2022, the three strategic announcements closed in the fourth quarter of 2021 and the newly announced participation in the BANGL joint venture provide an opportunity for Rattler to continue to grow the business. Building out greenfield water infrastructure on assets acquired as part of the drop down, as well as the expansion of gas processing and NGL takeaway for Diamondback and other producers as part of the WTG and BANGL joint ventures, will result in higher capital expenditures this year. However, such expenditures will result in a sustainable and growing Free Cash Flow profile in 2023 and beyond. Lastly, in keeping with Rattler's history of prioritizing return of the free cash flow produced by the business, we are increasing our distribution by 20% to $1.20 per unit annualized as a reflection of the confidence in the future trajectory of the business."

OPERATIONS AND FINANCIAL UPDATE

During the fourth quarter of 2021, the Company recorded total operating income of $47.3 million, an increase of 6% compared to the third quarter of 2021. During the fourth quarter of 2021, the Company recorded consolidated net income (including non-controlling interest) of $44.5 million, an increase of 14% from the third quarter of 2021. Fourth quarter 2021 Adjusted EBITDA (including non-controlling interest and as defined and reconciled below) was $80.8 million, an increase of 8% from the third quarter of 2021.

COMMON UNIT REPURCHASE PROGRAM

On October 29, 2020, the Board of Directors of Rattler's general partner approved a common unit repurchase program to acquire up to $100.0 million of Rattler's outstanding common units through December 31, 2021.

In total from the program's inception through February 18, 2022, Rattler has repurchased 6.3 million common units for a total cost of $64.9 million, utilizing 43% of the $150.0 million authorization.

The Company intends to purchase common units under the repurchase program opportunistically with cash on hand, free cash flow from operations and proceeds from potential liquidity events such as the sale of assets. The repurchase program may be suspended from time to time, modified, extended or discontinued by the Board of Directors of Rattler's general partner at any time. Purchases under the repurchase program may be made from time to time in open market or privately negotiated transactions in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended, and will be subject to market conditions, applicable legal requirements, contractual obligations and other factors. Any common units purchased as part of this program will be retired.

The transaction was approved by the Conflicts Committee of the Board of Directors of Rattler's general partner.

All statements, other than statements of historical fact, including statements regarding Rattler's: future performance; business strategy; future operations; estimates and projections of revenues, losses, costs, expenses, returns, cash flow, and financial position; anticipated benefits of strategic transactions (including acquisitions and divestitures); and plans and objectives of management (including plans for future cash flow from operations) are forward-looking statements. When used in this news release, the words "aim," "anticipate," "believe," "continue," "could," "estimate," "expect," "forecast," "future," "guidance," "intend," "may," "model," "outlook," "plan," "positioned," "potential," "predict," "project," "seek," "should," "target," "will," "would," and similar expressions (including the negative of such terms) as they relate to Rattler are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. Although Rattler believes that the expectations and assumptions reflected in its forward-looking statements are reasonable as and when made, they involve risks and uncertainties that are difficult to predict and, in many cases, beyond Rattler's control. Accordingly, forward-looking statements are not guarantees of future performance and Rattler's actual outcomes could differ materially from what Rattler has expressed in its forward-looking statements.

Factors that could cause the outcomes to differ materially include (but are not limited to) the following: changes in supply and demand levels for oil, natural gas, and natural gas liquids, and the resulting impact on the price for those commodities; the impact of public health crises, including epidemic or pandemic diseases such as the COVID-19 pandemic, and any related company or government policies or actions; actions taken by the members of OPEC and Russia affecting the production and pricing of oil, as well as other domestic and global political, economic, or diplomatic developments; regional supply and demand factors, including delays, curtailment delays or interruptions of production, or governmental orders, rules or regulations that impose production limits; federal and state legislative and regulatory initiatives relating to hydraulic fracturing, including the effect of existing and future laws and governmental regulations; and the risks and other factors disclosed in Rattler's filings with the Securities and Exchange Commission, including its Forms 10-K, 10-Q and 8-K, which can be obtained free of charge on the Securities and Exchange Commission's web site at http://www.sec.gov.

In light of these factors, the events anticipated by Rattler's forward-looking statements may not occur at the time anticipated or at all. Moreover, Rattler operates in a very competitive and rapidly changing environment and new risks emerge from time to time. Rattler cannot predict all risks, nor can it assess the impact of all factors on its business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those anticipated by any forward-looking statements it may make.

All forward-looking statements speak only as of the date of this news release or, if earlier, as of the date they were made. Rattler does not intend to, and disclaims any obligation to, update or revise any forward-looking statements unless required by applicable law.

NON-GAAP FINANCIAL MEASURES

Adjusted EBITDA is a supplemental non-GAAP financial measure used by management and external users of its financial statements, such as industry analysts, investors, lenders and rating agencies. Management believes Adjusted EBITDA is useful because the measure allows it to more effectively evaluate the Company's operating performance and compare the results of its operations period to period without regard to its financing methods or capital structure.

The Company defines Adjusted EBITDA as net income (loss) attributable to the Company plus net income (loss) attributable to non-controlling interest before interest expense (net of amount capitalized), depreciation, amortization and accretion on assets and liabilities of Rattler Midstream Operating LLC, its proportional depreciation and interest expense related to equity method investments, its proportional impairments and abandonments related to equity method investments, non-cash unit-based compensation expense, impairment and abandonments, (gain) loss on disposal of assets, (gain) loss from sale of equity method investment, provision for income taxes and other. The GAAP measure most directly comparable to Adjusted EBITDA is net income (loss). However, Adjusted EBITDA should not be considered an alternative to net income (loss) or any other measure of financial performance or liquidity presented in accordance with generally accepted accounting principles in the United States ("GAAP"). The Company excludes the items listed above from net income (loss) in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. As such, Adjusted EBITDA as presented below may not be comparable to similarly titled measures of other companies, and may not be comparable to similarly titled measures in Rattler Midstream Operating LLC's credit agreement and in the indenture that governs its senior notes. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company's financial performance, such as a company's cost of capital and tax structure, as well as historic costs of depreciable assets.

This release provides 2022 guidance for Adjusted EBITDA (non-GAAP measure) and net income (loss) (the comparable GAAP measure). We do not provide guidance on the reconciling items between forecasted net income (loss) and forecasted Adjusted EBITDA due to the uncertainty regarding timing and estimates of these items. We provide a range for the forecasts of net income (loss) and Adjusted EBITDA to allow for the variability in timing and uncertainty of estimates of reconciling items between forecasted net income (loss) and forecasted Adjusted EBITDA. Such reconciling items could be significant. Therefore, we cannot reconcile forecasted net income (loss) to forecasted Adjusted EBITDA without unreasonable effort.

The following table presents a reconciliation of net income (loss), the most directly comparable GAAP financial measure, to Adjusted EBITDA for each of the periods indicated:

Adjusted net income (loss) is a supplemental non-GAAP financial measure equal to net income (loss) attributable to Rattler Midstream LP plus net income (loss) attributable to non-controlling interest adjusted for (gain) loss on disposal of assets and related income tax adjustments. Management believes adjusted net income (loss) is useful because the measure provides useful information to analysts and investors for analysis of its operating results on a consistent, comparable basis from period to period. The Company's computation of adjusted net income (loss) may not be comparable to other similarly titled measures of other companies or to such measure in our credit facility or any of our other contracts.

The following table presents a reconciliation of net income (loss) attributable to Rattler Midstream LP to adjusted net income (loss) for each of the periods indicated:

Operating cash flow before working capital changes, which is a supplemental non-GAAP financial measure, represents net cash provided by operating activities as determined under GAAP without regard to changes in operating assets and liabilities. The GAAP financial measure most directly comparable to operating cash flow before working capital changes is net cash provided by operating activities. Management believes operating cash flow before working capital changes is an accepted measure which reflects cash flow from operating activities, additions to property, plant and equipment and net investments in its equity method investments across periods on a consistent basis. The Company also uses this measure because adjusted operating cash flow relates to the timing of cash receipts and disbursements that the Company may not control and may not relate to the period in which the operating activities occurred. This allows the Company to compare its operating performance with that of other companies without regard to financing methods and capital structure.

Free Cash Flow, which is a supplemental non-GAAP financial measure, is operating cash flow before working capital changes net of additions to property, plant and equipment and distributions from equity method investments. The GAAP financial measure most directly comparable to Free Cash Flow is net cash provided by operating activities. Management believes that Free Cash Flow is useful to investors as it provides the amount of cash available for reducing debt, investing in additional capital projects or paying dividends. This measure should not be considered as an alternative to, or more meaningful than, net cash provided by operating activities as an indicator of operating performance. The Company's computation of operating cash flow before working capital changes and Free Cash Flow may not be comparable to other similarly titled measures of other companies.

The following tables present a reconciliation of net cash provided by operating activities to operating cash flow before working capital changes and Free Cash Flow:
