Exhibit

HOUSTON – (PR NEWSWIRE) – November 8, 2018 – Western Gas Partners, LP (NYSE:WES) (“WES”) and Western Gas Equity Partners, LP (NYSE:WGP) (“WGP” or the “Partnership”) today announced they have entered into a merger agreement (the “Agreement”) whereby WGP will acquire all the publicly held common units of WES and substantially all of the units owned by Anadarko Petroleum Corporation (NYSE: APC) (“APC”) in a unit-for-unit, tax-free exchange (the “Simplification Transaction”). WES will survive as a partnership with no publicly traded equity and remain the borrower for all existing and future debt issuances, as well as the owner of all operating assets and equity investments. WGP will own 98% of WES, and APC will own the remaining 2%. In conjunction with the Simplification Transaction, WES has agreed to acquire substantially all of APC’s remaining midstream assets for a price of $4.015 billion (the “Acquisition,” and together with the Simplification Transaction, the “Transactions”). The Transactions were negotiated and unanimously approved by the Special Committees of the Boards of Directors of the general partners of WGP and WES, and were also unanimously approved by the Boards of Directors of the general partners of WGP and WES, and the APC Board of Directors.

“The transactions we announced today will transform the Western Gas franchise, and put it on a new, stronger footing for continued success in the future. We have executed these transactions at a time when we are realizing strong organic cash flow growth and expanding distribution coverage,” said Chief Executive Officer, Benjamin Fink. “This step serves to strengthen our already considerable competitive advantages via a lower cost of equity and a clean, simple capital structure. We are delighted to have been able to structure a transaction in which we expect all unitholders will realize annual distribution growth in 2019, as well as an enhanced long-term distribution growth profile.”

Under the terms of the Agreement, the public unitholders of WES will receive 1.525 units of WGP per WES unit owned. This represents a 7.6% premium to WES’s closing price on November 7, 2018. The WES common units currently owned by Anadarko, including the Class C units, will be converted into WGP common units at closing at the same exchange ratio. In addition, the WES IDRs and general partner units will be exchanged for newly issued WES common units.

⁽²⁾ System statistics, including mileage and capacities, are as of September 30, 2018.

The Simplification Transaction will not be taxable to either WES or WGP unitholders and is expected to close in the first quarter of 2019, subject to the approval of holders of a majority of the WES common units, regulatory approvals, and other customary closing conditions.

The WGP Special Committee, consisting of directors not associated with management or APC, evaluated the Transactions on behalf of the public unitholders and the WGP Board of Directors. The WGP Special Committee unanimously recommended approval of the Transactions to the Board of Directors of WGP. The WES Special Committee, consisting of directors not associated with management or APC, evaluated the Transactions on behalf of the WES Board of Directors and the public unitholders and also unanimously recommended approval of the Transactions to the WES Board of Directors. The Transactions were unanimously approved by the Board of Directors of each of WGP, WES and APC.

On a pro forma basis, WGP’s portfolio will be highly focused on the Delaware and DJ Basins, which WGP forecasts will generate 40% and 37%, respectively, of its expected 2019 Adjusted EBITDA¹, with an additional 10% generated from investments in long haul transportation and fractionation assets. Additionally, on a run-rate basis, WGP forecasts that 97% of the pro forma portfolio’s Adjusted gross margin¹ will be generated by long-term, fixed-fee contracts, with approximately 66% of natural gas throughput and approximately 80% of liquids throughput supported by either minimum volumetric commitments with associated deficiency payments or cost of service commitments.

“As a result of this transaction, we are now one of the largest midstream service providers in the U.S. The significantly accretive acquisition of virtually all of Anadarko’s midstream assets perfectly complements our Delaware and DJ natural gas infrastructure by adding overlapping oil and produced water gathering and disposal assets,” said Chief Operating Officer, Gennifer Kelly. “Our enhanced ability to offer integrated midstream services will provide meaningful additional competitive advantages and economies of scale in each basin.”

To fund the cash consideration of the Acquisition, WES has received an underwritten commitment for a $2.0 billion senior unsecured term loan facility (the “Term Loan”), which will close concurrently with the closing of the Transactions. The $2.008 billion of WES units issued to APC as part of the Acquisition consideration will be issued at a price of $43.87 per unit, which is based on the 30 day VWAP as of November 6, 2018. A portion of such common units will not convert into WGP common units in order for APC to maintain a 2% interest in WES. The remainder will convert into WGP common units at a ratio of 1.4056 to 1 (which represents no premium to the 30 day VWAPs for WES and WGP as of November 6, 2018). After giving effect to the Transactions, WGP estimates that there will be approximately 453 million common units outstanding, and APC will own approximately 55.5% of WGP. The public float of WGP will be more than 4x greater than its current public float of approximately 49 million units.

WES believes that it will maintain its current ratings and outlooks with all three major ratings agencies. The pro-forma leverage ratio at the end of 2019 is expected to be between 4.0x to 4.25x and return to a range of 3.5x to 4.0x in 2020 without the need for future equity issuance.

WGP expects that WES’s existing unitholders will receive a 2019 full-year distribution that is 1% to 2% higher than its estimated 2018 full-year distribution of $3.83 per unit. Additionally, WGP expects that its current unitholders will receive a 2019 full-year distribution that is 6% to 8% higher than its estimated 2018 full-year distribution of $2.36 per unit. In 2020 and 2021, WGP expects that the pro forma portfolio will be capable of continuing to grow distributions annually by 6% to 8% while generating distribution coverage of over 1.3x with expanding distribution coverage in each year. Furthermore, given its significantly increased overall scale and focus on key basins, WGP announced that following the close of the Transactions it will begin providing quarterly disclosure of: (i) DJ and Delaware Basin volumes and (ii) produced water gathering and disposal volumes separately from crude oil and NGL volumes.

“Our outlook reflects the combination of an immediately accretive acquisition with an organic portfolio that was already projected to generate over 20% Adjusted EBITDA growth in 2019,” said Chief Financial Officer, Jaime Casas. “We believe the resulting portfolio will continue to generate healthy cash flow growth and distribution coverage, thus enabling us to execute our capital plan without the need for equity financing.”
