17. SEGMENTS

Midstream Logistics and Pipeline Transportation are our operating segments representing the Company’s segments for which discrete financial information are available and utilized on a regular basis by our CODM to make key operating decisions, assess performance and allocate resources. These segments represent strategic business units with differing products and services. No operating segments have been aggregated to form the reportable segments. Therefore, ourtwo operating segments represent our reportable segments. The activities of each of our reportable segments from which the Company earns revenues and incurs expenses are described below:

•Midstream Logistics: The Midstream Logistics segment operates under three revenue streams, 1) gas gathering and processing, 2) crude oil gathering, stabilization and storage services and 3) produced water gathering and disposal.

•Pipeline Transportation: The Pipeline Transportation segment consists of equity investment interests inthree Permian Basin pipelines that access various points along the U.S. Gulf Coast, Kinetik NGL Pipeline and Delaware Link Pipeline. The current operating pipelines transport crude oil, natural gas and NGLs.

Our Chief Executive Officer, who is the CODM, uses segment net income or loss including noncontrolling interest adjusted for interest, taxes, depreciation and amortization, gain or loss on disposal of assets and debt extinguishment, the proportionate EBITDA from our EMI pipelines, equity income and gain from sale of investments recorded using the equity method, share-based compensation expense, noncash increases and decreases related to commodity hedging activities, fair value adjustments to contingent liabilities, integration and transaction costs and extraordinary losses and unusual or non-recurring charges (“Segment Adjusted EBITDA”) to assess performance of each operating segment. For both segments, the CODM uses Segment Adjusted EBITDA to allocate resources. The CODM considers budget-to-actual and forecast-to-actual variances on a monthly basis for both measures when making decisions about allocating capital and personnel to the segments.

The Midstream Logistics segment accounts for more than 99% of the Company’s operating revenues, cost of sales (excluding depreciation and amortization), operating expenses and ad valorem expenses. The Pipeline Transportation segment contains all of the Company’s equity method investments, which contribute more than 92% of the segment’s adjusted EBITDA. Corporate and Other activities contain the Company’s executive and administrative functions, including more than 78% of the Company’s general and administrative expenses and all of the Company’s debt service costs.

The Company regularly provides management reports to the CODM that include cost of sales, operating, general and administrative expenses related to the segments, which are all considered to be significant.
