SCOTTSDALE, AZ April 27, 2011—Kona Grill, Inc. (Nasdaq: KONA), an American grill and sushi bar, reported financial results for the first quarter ended March 31, 2011.

First Quarter 2011 Highlights

· Restaurant sales increased 12.3% to $23.6 million

· Same-store sales increased 7.6%

· Restaurant operating profit margin increased to 14.0%

“We’ve continued the sales momentum reported at the end of the year with a 7.6% increase in same-store sales in the first quarter,” said Marc Buehler, President and Chief Executive Officer of Kona Grill. “We continue to enjoy positive results from the various marketing and menu improvement initiatives implemented over the past year.

“Although we continue to be impacted by higher commodity costs, we have been able to leverage top-line sales to drive improved restaurant operating margins. The quarter’s results further support our forecast for achieving profitability in 2011.”

First Quarter 2011 Financial Results

Restaurant sales increased 12.3% to $23.6 million from $21.1 million in the same year-ago quarter. The improvement reflects a 7.6% increase in same-store sales driven by strong traffic and higher average guest check, as well as additional revenue from the Kona Grill in Baltimore, Maryland that opened during the fourth quarter of 2010. The 7.6% increase in same-store sales compares to a 6.4% increase in the prior quarter and a 2.5% decrease in the first quarter of 2010.

Average weekly sales for the 22 restaurants in the comparable base were $73,240 during the first quarter of 2011, compared to $68,050 in the same year-ago period. Average weekly sales for restaurants not in the comparable base were $70,340 during the first quarter of 2011, versus $60,650 in the same year-ago period.

Net loss for the first quarter of 2011 was $0.1 million or $0.01 per share, an improvement from a net loss of $0.9 million or $0.10 per share during the first quarter of 2010.

Financial Guidance

For the second quarter of 2011, the Company forecasts restaurant sales of $24.0 million to $25.0 million, and net income of $0.2 million to $0.4 million, or $0.02 to $0.04 per share.

Reconciliation of Restaurant Operating Profit to Loss from Operations

The Company defines restaurant operating profit to be restaurant sales minus cost of sales, labor, occupancy, and restaurant operating expenses.  Restaurant operating profit does not include general and administrative expenses, depreciation and amortization, or preopening expenses.  The Company believes restaurant operating profit is an important component of financial results because it is a widely used metric within the restaurant industry to evaluate restaurant-level productivity, efficiency, and performance.  The Company uses restaurant operating profit as a key metric to evaluate its restaurants' financial performance compared with its competitors.  Restaurant operating profit is not a financial measurement determined in accordance with generally accepted accounting principles ("GAAP") and should not be considered in isolation or as an alternative to loss from operations.  Restaurant operating profit may not be comparable to the same or similarly titled measures computed by other companies. The table below sets forth the Company's calculation of restaurant operating profit and a reconciliation to loss from operations, the most comparable GAAP measure (in thousands).
