Kona Grill Announces Preliminary Fourth Quarter 2014 Restaurant Sales

- Same-Store Sales Increase 3.1% -

SCOTTSDALE, AZ – January 12, 2015─ Kona Grill, Inc. (NASDAQ: KONA), an American grill and sushi bar, today announced preliminary restaurant sales for the fourth quarter of 2014, which ended December 31, 2014. Restaurant sales increased approximately 29.0% to $31.5 million, compared to $24.5 million for the same quarter last year. Same-store sales increased approximately 3.1% compared to an increase of 3.5% in the fourth quarter of 2013.

For fiscal year 2014, restaurant sales increased approximately 21.2% to $119.1 million, compared to $98.3 million for fiscal year 2013. The increase was driven by same-store sales of approximately 3.8% and incremental sales associated with the opening of seven new Kona Grill restaurants since October 2013, three of which were opened in the recently completed fourth quarter.

Berke Bakay, President and CEO of Kona Grill, commented, “We are excited to announce fourth quarter total restaurant sales and same-store sales both of which exceeded our expectations. We have now generated positive same-store sales in 17 of the last 18 quarters, which is a testament to the strength of our brand. For the fourth quarter of 2014, average weekly sales of our non-comp base restaurants exceeded the average weekly sales of our comp base restaurants which is further evidence that our new design and real estate efforts are generating strong interest from our customers. Given our strong fiscal year 2014 sales and our year-over-year acceleration of unit development to achieve our 20% target, we believe our uniquely positioned concept is poised to continue its restaurant sales growth momentum into 2015 and beyond.”

Kona Grill, Inc. will be presenting at the 17th Annual ICR XChange Investor Conference at the Grande Lakes Resort in Orlando, FL on Tuesday, January 13, 2015. Berke Bakay and Christi Hing, Chief Financial Officer, are hosting the presentation, which will begin at 8:30 am Eastern Time.
