FIESTA RESTAURANT GROUP, INC. SHAREHOLDERS RE-ELECT ALL THREE INCUMBENT DIRECTOR NOMINEES AT 2017 ANNUAL MEETING OF SHAREHOLDERS

DALLAS, Texas (June 7, 2017) – Fiesta Restaurant Group, Inc. (“Fiesta” or the “Company”) (NASDAQ: FRGI), parent company of the Pollo Tropical® and Taco Cabana® fast casual restaurant brands, today announced that, based on preliminary voting tabulations provided by the Company’s proxy solicitor, Fiesta shareholders have supported the re-election of all three Fiesta nominees to the Company’s Board of Directors: Barry J. Alperin, Stephen P. Elker and Brian P. Friedman. Fiesta believes that all of its director candidates received between 80% and 98% of the votes cast, or 89% and 97% excluding the dissident group’s shares. The vote results are subject to certification by the independent inspector of elections.

Fiesta’s Board of Directors issued the following statement:

“During the course of this election campaign, we had very insightful discussions with a great number of our shareholders, including JCP, and received important feedback. Consistent with our year-round commitment to investor engagement, we will continue to have frequent communications with our shareholders. The Board has also decided to conduct an overall review of its corporate governance and board composition, and to put forward a proposal to declassify the Board at its next Annual Meeting. While we understand that challenges continue to lie ahead, we are gratified by the broad support of Fiesta’s shareholders and look forward to revitalizing the Company’s iconic brands and continuing to improve its financial results with our new CEO, Rich Stockinger, Fiesta’s Renewal Plan, and a refreshed and expanded Board.”

The preliminary vote count provided by the Company’s proxy solicitor also indicates that Fiesta shareholders voted in favor of all other proposals submitted for a vote at the Annual Meeting. Fiesta will file final voting results with the SEC on Form 8-K once they are certified by the independent inspector of elections.
