SOUTHLAKE, TX — (GLOBE NEWSWIRE) — August 21, 2012 — Del Frisco’s Restaurant Group, Inc. (NASDAQ: DFRG), the owner and operator of the Del Frisco’s Double Eagle Steak House, Sullivan’s Steakhouse, and Del Frisco’s Grille restaurant concepts, reported financial results today for the second quarter ended June 12, 2012. The Company also provided an outlook for the full 2012 fiscal year.

Key highlights from the second quarter 2012 compared to the second quarter 2011 include:

“During the second quarter, we demonstrated the strength of our business model with solid comparable restaurant sales and significant increases in both restaurant-level EBITDA and overall profitability,” said Mark S. Mednansky, Chief Executive Officer of Del Frisco’s Restaurant Group, Inc. “Looking ahead, we are confident that our recent IPO has provided us the financial flexibility to pursue our stated long-term growth objectives and further establish Del Frisco’s as a leading ‘next generation’ full-service dining company.”

Initial Public Offering (“IPO”)

On August 1, 2012, and subsequent to the end of the second quarter, Del Frisco’s closed its IPO of 5.8 million shares of common stock at $13.00 per share. The Company received net proceeds of approximately $70.1 million from the IPO, which included approximately $5.3 million of underwriting discounts and commissions, and repaid $61.0 million under its credit facility. In addition, Del Frisco’s used $3.0 million of the net proceeds to make a one-time payment to Lone Star Fund in consideration for the termination of an asset advisory agreement upon consummation of the IPO. The remainder of the net proceeds will be used for working capital and other general corporate purposes. In conjunction with the repayment of amounts outstanding under the credit facility and subsequent to the end of the second quarter, the Company wrote-off approximately $1.7 million in unamortized debt issuance costs.

Prior to the IPO closing, Del Frisco’s converted from a limited liability company to a corporation and converted its then-outstanding membership interests into approximately 18.0 million shares of common stock. All issued and outstanding common stock and per share amounts contained in this earnings release and accompanying financial statements have been retroactively adjusted to reflect the conversion. On August 1, 2012, Del Frisco’s had a total of approximately 23.8 million common shares issued and outstanding.

Review of Second Quarter 2012 Operating Results

Total revenues increased $7.8 million, or 17.9%, to $51.3 million in the second quarter of 2012 from $43.5 million in the second quarter of 2011. This increase was primarily due to a 4.0% increase in total comparable restaurant sales and 29 additional operating weeks resulting from four restaurant openings since the second quarter last year. Total operating weeks for all concepts during the second quarter of 2012 increased to 373 from 344 in the second quarter of 2011.

Cost of sales increased $2.5 million, or 18.8%, to $15.8 million in the second quarter of 2012 from $13.3 million in the second quarter of 2011. As a percentage of consolidated revenues, consolidated cost of sales increased slightly to 30.7% from 30.6%.

Restaurant-level EBITDA* increased $2.8 million, or 28.6%, to $12.6 million in the second quarter of 2012 from $9.8 million in the second quarter of 2011. As a percentage of consolidated revenues, restaurant-level EBITDA increased to 24.5% from 22.6%.

Operating income increased by $3.2 million, or 97%, to $6.5 million in the second quarter of 2012 from $3.3 million in the second quarter of 2011. As a percentage of consolidated revenues, operating income increased to 12.7% from 7.5%.

Net income for the second quarter of 2012 was $3.6 million, or $0.20 per diluted share, compared to net income of $1.0 million, or $0.06 per diluted share in the second quarter of 2011. The share base was 18.0 million shares for both periods.

Segment Results

The Company operates the Del Frisco’s Double Eagle Steak House, Sullivan’s, and Del Frisco’s Grille brands as operating segments. The operations of Del Frisco’s Grille are included in the “Other” segment.

Del Frisco’s Double Eagle Steak House

Revenues increased $3.6 million, or 14.9%, to $27.8 million in the second quarter of 2012 from $24.2 million in the second quarter of 2011. The improvement was primarily due to a 7.3% increase in comparable restaurant sales, comprised of a 5.1% increase in average check and a 2.2% increase in entrée counts. This increase follows a comparable restaurant sales increase of 13.2% in the second quarter of last year. Operating weeks for the quarter increased to 108 from 104.

Restaurant-level EBITDA* increased 21% to $7.9 million in the second quarter of 2012 from $6.6 million in the second quarter of 2011, as the concept benefitted primarily from lower restaurant operating expenses which offset higher cost of sales and marketing and advertising costs as a percentage of revenues.

Sullivan’s

Revenues were consistent at approximately $19.3 million for each period. The slight 0.3% increase in comparable restaurant sales for the second quarter of 2012 was comprised of a 4.1% increase in average check which was partially offset by a 3.8% decrease in entrée counts. This increase follows a comparable restaurant sales increase of 11.2% in the second quarter of last year. Operating weeks for the quarter remained consistent at 240 for both periods.

Restaurant-level EBITDA* increased 5.6% to $3.5 million in the second quarter of 2012 from $3.3 million in the second quarter of 2011, as the concept benefitted primarily from lower cost of sales and restaurant operating expenses partially offset by higher marketing and advertising costs as a percentage of revenues.

Segment Information and Reconciliation of Non-GAAP Measurement

We prepare our financial statements in accordance with generally accepted accounting principles (GAAP). Within our press release, we make reference to non-GAAP Restaurant-level EBITDA. This non-GAAP measurement is calculated by adding back to operating income depreciation and amortization plus the sum of certain non-operating expenses, including pre-opening costs, management fees and expenses, and general and administrative expenses. We believe that this measure represents a useful internal measure of performance. Accordingly, we include this non-GAAP measure so that investors have the same financial data that management uses in evaluating performance, and we believe that it will assist the investment community in assessing our underlying performance on a quarter-over-quarter basis. However, because this measure is not determined in accordance with GAAP, such a measure is susceptible to varying calculations and not all companies calculate the measure in the same manner. As a result, this measure as presented may not be directly comparable to a similarly titled measure presented by other companies. This non-GAAP measure is presented as supplemental information and not as alternatives to any GAAP measurements. The following tables include a reconciliation of restaurant-level EBITDA to operating income:
