Grill Concepts 2006 First Quarter Total Revenues Up 12.1 Percent Over Prior-Year Period


LOS ANGELES, May 9, 2006 (PRIMEZONE) -- Grill Concepts, Inc. (Nasdaq:GRIL) today reported another period of record quarterly revenues for the three months ended March 26, 2006. Total revenues, including restaurant sales, cost reimbursements and management and license fees, rose 12.1 percent to $19.3 million from $17.2 million in the year-ago period.

For the 2006 first quarter, sales at company-owned restaurants grew 12.5 percent to $15.1 million from $13.4 million in the prior-year period. Management and license fees increased 18.0 percent to $420,000 from $356,000 in the year-ago first quarter. Same store sales improved 6.9 percent.

"We achieved strong sales at both our Daily Grill and Grill-branded restaurants, reflecting increases in guest counts and average checks," said Philip Gay, chief financial officer and incoming chief executive officer of Grill Concepts. "Benefiting from a 3.9% increase in comparable sales and contributions from our newer locations in Santa Monica and Downtown LA, opened in March and May, respectively, of 2005, weighted average weekly sales at our Daily Grill restaurants rose 6.4% to $66,000. We also experienced continued strength in sales at our Grill-branded restaurants, up 12.9% over the prior-year period."

Earnings before interest, taxes, depreciation and amortization (EBITDA) in the current first quarter totaled $1.1 million, compared with $1.3 million in the 2005 first quarter.

Net income for the 2006 first quarter totaled $482,000, or $0.08 per diluted share, based on 6,242,486 shares outstanding. Grill Concepts adopted Financial Accounting Standards Board Statement No. 123(R) related to expensing stock-based compensation on a prospective basis beginning in the first quarter of fiscal 2006, which reduced net income by $38,000 and diluted net income per share by $0.01 in the quarter. In the year-ago first quarter, the company posted net income of $682,000, or $0.11 per diluted share, based on 6,092,223 shares outstanding.

Gay added: "We are pleased with the progress being made in executing our strategic expansion plans. Our newest Grill-branded restaurant is on schedule to debut in the Dallas market late summer this year as part of the renowned Galleria shopping complex.

"Separately, we announced today plans to enter the Memphis market with the 2007 opening of a Daily Grill restaurant adjacent to the FedExForum, home to the NBA's Memphis Grizzlies, and centrally located within the Beale Street entertainment district, on of Tennessee's top tourist attractions," Gay said. "This new restaurant, which will be located in the Westin Beale Street Hotel, a $40 million Starwood Hotels & Resorts project currently under construction, demonstrates the success of our efforts to revitalize our Starwood alliance in an improved economy. With a number of other new sites currently being negotiated and backed by a new $8 million credit facility to support our growth initiatives, we believe the prospects for our company are greater than ever."

Non-GAAP Financial Measure

The company believes that EBITDA, although a non-GAAP measure, provides greater comparability regarding its ongoing operating performance.

A reconciliation of the company's U.S. GAAP information to EBITDA is provided in the attached table.

Such statements include, but are not limited to, the company's ability to continue expanding its restaurant network and projected opening dates of the Dallas and Memphis restaurants.
