Leading Proxy Advisory Firm ISS Recommends Fiesta Shareholders Vote “FOR” All Fiesta Director Nominees

ISS Notes Dissident’s Failure to Make Compelling Case for Change

Fiesta Urges Shareholders to Follow ISS’ Recommendation and Vote on the WHITE Proxy Card

DALLAS, Texas (May 30, 2017) – Fiesta Restaurant Group, Inc. (“Fiesta” or the “Company”) (NASDAQ: FRGI), parent company of the Pollo Tropical® and Taco Cabana® fast casual restaurant brands, announced today that leading independent proxy advisory firm Institutional Stockholder Services (“ISS”) has recommended that Fiesta shareholders vote on the WHITE proxy card “FOR” all of the Company’s highly qualified slate of nominees: Barry J. Alperin, Stephen P. Elker and Brian P. Friedman. ISS recommended that stockholders do not vote for the two nominees proposed by a dissident group of several activist hedge funds led by JCP Investment Management, LLC (collectively, the “Pappas Group” or “JCP”) at the Company’s June 7, 2017 Annual Meeting of Shareholders.

In recommending that Fiesta shareholders vote “FOR” Messrs. Alperin, Elker and Friedman in its May 26, 2017 report, ISS said¹:

● “The dissident has failed to make a compelling case that change at the board level is necessary at this time.”

● “[It] appears the board had already recognized and begun addressing the problems at hand, particularly the problems stemming from the expansion plan, by the time the dissident began its engagement, and has since taken appropriate steps to course-correct.”

● “The company expanded its board by adding Stockinger and two new directors with extensive backgrounds in the restaurant industry: Paul Twohig, formerly of Dunkin' Donuts, Starbucks and Panera Bread; and Nicholas [Shepherd], who had been CEO of TGI Friday's.”

● “As such, the dissident has not presented a compelling case that additional change is necessary at this time; therefore votes on the WHITE card for all management nominees are warranted.”

Commenting on the ISS report, Fiesta Board Chair, Stacey Rauch, issued the following statement:

“We are pleased that ISS supports and recommends the reelection of Fiesta’s experienced and engaged incumbent director nominees, recognizes the strength of the recently implemented Renewal Plan, and ultimately concludes that change to the Company’s Board of Directors is not warranted. ISS’ recommendation notes the ‘vigorous corrective actions’ Fiesta’s Board has taken, especially those actions taken prior to the dissident group’s engagement, to ensure that the Company has the right leadership team and right strategy in place to maximize value for all shareholders.”

Richard Stockinger, Fiesta’s CEO, President and Director, added, “ISS’ recommendation reaffirms my belief that Fiesta has the right Board in place to oversee the ongoing implementation of the Renewal Plan, which is already yielding positive results. I look forward to continuing the execution of this detailed plan to revitalize our great brands, deliver a great dining experience to our valued guests and create long-term value for all of our shareholders.”

With the Annual Meeting rapidly approaching, Fiesta urges shareholders to protect the value of their investment by voting today “FOR” ALL of the Company’s highly-qualified director nominees on the WHITE proxy card: Barry J. Alperin, Stephen P. Elker and Brian P. Friedman.

Shareholders can vote by completing, dating and signing the Company-provided WHITE proxy card, or by telephone or the internet by following the instructions on the WHITE proxy card.
