Exhibit 99.1

EXCO Resources, Inc. Announces 1-for-15 Reverse Share Split, Shareholder Approval for Share Issuance under 1.5 Lien Notes and 1.75 Term Loans, and Annual Meeting Results

06/01/2017

DALLAS—EXCO Resources, Inc. (NYSE: XCO) (“EXCO” or the “Company”) today announced that its Board of Directors (the “Board”) has approved a 1-for-15 reverse share split of its common stock. The Company’s shareholders granted authority to the Board to effect the reverse share split at the Company’s 2017 Annual Meeting of Shareholders on May 31, 2017 (the “Annual Meeting”). The reverse share split is expected to become effective after the market closes on June 12, 2017. The Company’s common stock will continue to trade on the NYSE under the symbol “XCO” and is expected to begin trading on a post-split basis when the market opens on June 13, 2017.

The shareholder and Board approval of the reverse share split and the shareholder approval to issue additional shares of the Company’s common stock allow the Company, subject to certain limitations, to pay interest in common shares on both its senior secured 1.5 lien notes and its senior secured 1.75 lien term loans. Harold L. Hickey, EXCO’s Chief Executive Officer and President, commented, “We believe the successful completion of the reverse share split and the passage of the charter amendment allowing use of shares to pay interest provide a number of immediate benefits. We will be able to comply with NYSE listing standards and significantly reduce our cash interest payments. This will allow us to create value for our shareholders by investing our cash in the business as opposed to making interest payments.”

Once the reverse share split is effected, every 15 shares of EXCO’s issued and outstanding common stock (and such shares held in treasury) will be converted into one share of common stock. The reverse share split and related charter amendment will disproportionately reduce the number of the Company’s authorized common shares from 780 million to 260 million. No fractional shares will be issued for the reverse share split. Instead, the Company will round fractional shares upwards to the next whole share. The new CUSIP number for the Company’s common stock post-reverse share split is 269279 501.

Continental Stock Transfer & Trust Company, LLC (“Continental Stock”), the Company’s transfer agent, will act as the exchange agent for the reverse share split. Shareholders with certificated shares will receive a letter of transmittal from Continental Stock with instructions on how to surrender certificates representing pre-split shares. Shareholders should not send in their pre-split certificates until they receive a letter of transmittal from Continental Stock. Shareholders with book-entry shares or who hold their shares through a bank, broker or other nominee will not need to take any action. Please contact Continental Stock for further information at (212) 509-4000.

Additional information about the reverse share split, the related charter amendment, and the issuance of common shares by the Company can be found in the Company’s definitive proxy statement filed with the Securities and Exchange Commission (“SEC”) on April 24, 2017.
