WESTERN GAS ANNOUNCES

THIRD-QUARTER 2017 RESULTS

UPDATES 2017 CAPITAL EXPENDITURE OUTLOOK

HOUSTON, October 31, 2017 – Western Gas Partners, LP (NYSE: WES) (“WES” or the “Partnership”) and Western Gas Equity Partners, LP (NYSE: WGP) (“WGP”) today announced third-quarter2017 financial and operating results.

WESTERN GAS PARTNERS, LP

Net income (loss) available to limited partners for the third quarter of 2017 totaled $65.1 million, or $0.38 per common unit (diluted), with third-quarter2017 Adjusted EBITDA⁽¹⁾ of $257.8 million and third-quarter2017 Distributable cash flow⁽¹⁾ of $231.9 million.

WES previously declared a quarterly distribution of $0.905 per unit for the third quarter of 2017. This distribution represented a 2%increase over the prior quarter’s distribution and a 7%increase over the third-quarter2016 distribution of $0.845 per unit. The third-quarter2017 Coverage ratio⁽¹⁾ of 1.09 times was based on the quarterly distribution of $0.905 per unit.

“Our portfolio continues to display strong quarterly performance, driven by accelerated producer activity in the DJ and Delaware Basins, despite the over $3.0 million impact to Adjusted EBITDA associated with extreme weather events,” said Chief Executive Officer, Benjamin Fink. “Our Ramsey processing facility is nearing capacity as we prepare to commission Ramsey VI later this quarter, and we remain confident that the growing production in the Delaware and DJ Basins will support the significant processing capacity we are adding at our new Mentone and Latham facilities, both of which are on schedule.”

⁽¹⁾ Please see the tables at the end of this release for a reconciliation of GAAP to non-GAAP measures and calculation of the Coverage ratio.

Total throughput for crude, NGL and produced water assets for the third quarter of 2017 averaged 209 MBbls/d, which was 15% above the prior quarter and 13% above the third quarter of 2016.

Western Gas Partners, LP Reconciliation of GAAP to Non-GAAP Measures

Below are reconciliations of (i) net income (loss) attributable to Western Gas Partners, LP (GAAP) to WES’s Distributable cash flow (non-GAAP), (ii) net income (loss) attributable to Western Gas Partners, LP (GAAP) and net cash provided by operating activities (GAAP) to Adjusted EBITDA attributable to Western Gas Partners, LP (“Adjusted EBITDA”) (non-GAAP), and (iii) operating income (loss) (GAAP) to Adjusted gross margin attributable to Western Gas Partners, LP (“Adjusted gross margin”) (non-GAAP), as required under Regulation G of the Securities Exchange Act of 1934. Management believes that WES’s Distributable cash flow, Adjusted EBITDA, Adjusted gross margin, and Coverage ratio are widely accepted financial indicators of WES’s financial performance compared to other publicly traded partnerships and are useful in assessing its ability to incur and service debt, fund capital expenditures and make distributions. Distributable cash flow, Adjusted EBITDA, Adjusted gross margin and Coverage ratio, as defined by WES, may not be comparable to similarly titled measures used by other companies. Therefore, WES’s Distributable cash flow, Adjusted EBITDA, Adjusted gross margin and Coverage ratio should be considered in conjunction with net income (loss) attributable to Western Gas Partners, LP and other applicable performance measures, such as operating income (loss) or cash flows from operating activities.
