Fiesta Restaurant Group, Inc. Reports First Quarter 2014 Results

Addison, Texas - (Business Wire) - May 6, 2014-Fiesta Restaurant Group, Inc. (“Fiesta” or the “Company”) (NASDAQ: FRGI), the owner, operator, and franchisor of the Pollo Tropical® and Taco Cabana® fast-casual restaurant brands, today reported results for the first quarter 2014, which ended on March 30, 2014.

Highlights of first quarter 2014 results include:

• Total revenues increased 8.8% to $145.4 million;

• Comparable restaurant sales increased 6.3% and comparable restaurant guest traffic increased 4.6% at Pollo Tropical;

• Comparable restaurant sales increased 0.8% and comparable restaurant guest traffic decreased 2.0% at Taco Cabana, negatively impacted by unfavorable weather and fewer newly remodeled restaurants;

• Four Company-owned Pollo Tropical restaurants were opened, including the first restaurant in Texas;

• Net income increased $3.9 million to $8.7 million, or $0.33 per diluted share, compared to net income of $4.8 million, or $0.20 per diluted share.

Fiesta President and Chief Executive Officer Tim Taft commented, “With a successful start to 2014, we increased revenues by almost nine percent, expanded operating margins and grew EPS over 60%. We also opened our newest Pollo Tropical restaurant prototype in Addison, Texas. This is the first of approximately 10 slated to open in three key Texas markets in 2014.”

Taft continued, “In April, we opened our first Cabana Grill restaurant in the greater Atlanta market. In addition to the westward expansion of Pollo Tropical and testing Cabana Grill in the east, we continue to focus our development efforts on building Pollo Tropical restaurants in markets where we already have presence, driving profitable growth.”

First Quarter 2014 Financial Review

Consolidated Results

Total revenues increased 8.8% in the first quarter of 2014 to $145.4 million from $133.6 million in the first quarter of 2013. Restaurant sales in the first quarter of 2014 increased 8.8% to $144.8 million from $133.1 million in the first quarter of 2013 due to the opening of new Company-owned restaurants and comparable restaurant sales growth.

Cost of sales decreased as a percentage of restaurant sales in the first quarter of 2014 compared to the prior year period as modest price increases and supply chain management initiatives more than offset commodity cost increases.

Restaurant wages and related expenses improved as a percentage of restaurant sales in the first quarter of 2014 compared to the prior year period due primarily to lower workers’ compensation claim costs along with the favorable impact of sales increases on fixed costs.

Other restaurant operating expenses increased slightly as a percentage of restaurant sales in the first quarter of 2014 compared to the prior year period. Pre-opening costs were $0.7 million compared to $0.8 million in the prior year period due to the timing of expenses for future openings. Rent expense increased slightly as a percentage of restaurant sales compared to the prior year period as a consequence of new Company-owned restaurant openings and sale-leaseback transactions completed over the course of a year.

Advertising expense increased as a percentage of restaurant sales in the first quarter of 2014 compared to the prior year period due primarily to an increase in expenditures and the timing of promotions.

General and administrative expenses were $12.2 million in both the first quarters of 2014 and 2013 and decreased as a percentage of restaurant sales in the first quarter of 2014 due to the favorable impact of higher sales on fixed costs.

Depreciation and amortization increased to $5.3 million in the first quarter of 2014 compared to $4.8 million in the prior year period. This increase was due to new Company-owned restaurant development, partially offset by the impact of sale-leaseback transactions.

Interest expense decreased $4.4 million to $0.6 million in the first quarter of 2014 from $5.0 million in the first quarter 2013 due to the reduction in Fiesta’s outstanding debt and a lower interest rate on borrowings under the new senior credit facility.

The provision for income taxes for the first quarter of 2014 was derived using an estimated annual effective income tax rate for 2014 of 38.3%, while the provision for income taxes for the first quarter of 2013 was derived using an estimated effective annual income tax rate for 2013 of 35.8%, excluding discrete items. The estimated effective annual income tax rate for 2014 is higher than the estimated effective annual income tax rate for the first quarter of 2013, primarily due to the expiration of the Work Opportunity Tax Credit on December 31, 2013.

Net income was $8.7 million, or $0.33 per diluted share (on a base of 26.2 million shares), compared to net income of $4.8 million, or $0.20 per diluted share (on a base of 22.9 million shares), in the first quarter of 2013.

Brand Results

Pollo Tropical restaurant sales increased 15.3% to $71.4 million in the first quarter of 2014 from $61.9 million in the first quarter of 2013 due to a comparable restaurant sales increase of 6.3% along with a net increase of 13 Company-owned restaurants. This is the eighteenth consecutive quarter the brand has delivered comparable restaurant sales growth and, on a two year basis, first quarter comparable restaurant sales grew 10.1%. The growth in comparable restaurant sales resulted from a 4.6% increase in comparable restaurant guest traffic along with a 1.7% increase in average check. Adjusted EBITDA for Pollo Tropical, a non-GAAP financial measure, increased to $13.7 million in the first quarter of 2014 from $9.8 million in the first quarter of 2013.

Taco Cabana restaurant sales increased 3.2% to $73.5 million in the first quarter of 2014 from $71.2 million in the first quarter of 2013 due to a 0.8% increase in comparable restaurant sales along with a net increase of three Company-owned restaurants. On a two year basis, first quarter comparable restaurant sales grew 2.8%. The increase in comparable restaurant sales resulted from a decrease of 2.0% in comparable restaurant guest traffic negatively impacted by unfavorable weather conditions in Texas and fewer newly remodeled restaurants, partially offset by a 2.8% increase in average check. Menu price increases drove an increase in restaurant sales of 1.3% while the remaining increase in average check is primarily driven by a positive change in sales mix due to the implementation of new menu boards. Adjusted EBITDA for Taco Cabana, a non-GAAP financial measure, increased to $7.1 million in the first quarter of 2014 from $6.5 million in the first quarter of 2013.

Restaurant Development

During the first quarter of 2014, Fiesta opened four new Company-owned Pollo Tropical restaurants, one in Texas and three in Florida. Subsequent to the end of the first quarter of 2014, the Company opened its first Cabana Grill restaurant in Snellville, Georgia, outside of Atlanta.

As of March 30, 2014, the Company owned and operated 106 Pollo Tropical restaurants and 165 Taco Cabana restaurants and franchised 39 Pollo Tropical restaurants in the U.S., Puerto Rico, the Bahamas, Costa Rica, Ecuador, Guatemala, Honduras, India, Panama, Trinidad & Tobago, Venezuela and the Dominican Republic, and seven Taco Cabana restaurants in the U.S.

Supplemental Non-GAAP Information

The following table sets forth certain unaudited supplemental financial data for the periods indicated

(in thousands):

Adjusted EBITDA and Restaurant-Level Adjusted EBITDA are non-GAAP financial measures. Adjusted EBITDA is defined as earnings before interest, income taxes, depreciation and amortization, impairment and other lease charges, stock-based compensation expense and other income and expense. Adjusted EBITDA for each of our segments includes an allocation of general and administrative expenses associated with administrative support for executive management, information systems and certain accounting, legal and other administrative functions. Restaurant-Level Adjusted EBITDA is defined as Adjusted EBITDA excluding franchise royalty revenues and fees and general and administrative expenses (including corporate-level general and administrative expenses). Adjusted EBITDA for each of our segments is a measure of segment profitability reported to our chief operating decision maker for purposes of allocating resources to the segments and assessing each segment's performance. In addition, management believes that Adjusted EBITDA and Restaurant-Level Adjusted EBITDA, when viewed with our results of operations calculated in accordance with GAAP and our reconciliation of Restaurant-Level Adjusted EBITDA and Adjusted EBITDA to net income (i) provides useful information (including at the restaurant level) about our operating performance and period-over-period growth, (ii) provides additional information that is useful for evaluating the operating performance of our business, and (iii) permits investors to gain an understanding of the factors and trends affecting our ongoing earnings, from which capital investments are made and debt is serviced. However, such measures are not a measure of financial performance or liquidity under GAAP and, accordingly, should not be considered as an alternative to net income or net income per share as indicators of operating performance or liquidity. Also these measures may not be comparable to similarly titled captions of other companies.
