SCOTTSDALE, AZ, February 13, 2014—Kona Grill, Inc. (NASDAQ: KONA), an American grill and sushi bar, reported financial results for its fourth quarter and full year ended December 31, 2013.

Fourth Quarter 2013 Highlights vs. Year-Ago Quarter

Management Commentary

“In the fourth quarter, we achieved our third straight quarter of same-store sales growth, despite macro challenges including a shortened holiday shopping season and inclement weather,” said Berke Bakay, president and CEO of Kona Grill. “This growth is attributed to our differentiated concept and compelling sales initiatives, and we’ve seen the traffic gap relative to our peers widen. Our guest traffic during the fourth quarter grew 2.7%, which represents our best traffic growth of the year, while Knapp Track traffic declined 3.7%.

“Our strategy of transitioning back into a growth company is well underway and our two new locations are performing well. In October, we opened in Boise, which is our first new restaurant since 2010, and in December, we opened in The Woodlands, which is our second restaurant in the Houston market. Average weekly sales for our new restaurants were over $100,000 in the fourth quarter, compared to approximately $80,000 for our existing base.

“In November, we also completed remodels of our Scottsdale and San Antonio restaurants, which incorporated modern design elements being used in our new locations. Early results from these two remodels are outstanding and we anticipate stronger operating results from them in 2014.

“Excitement around our brand is intensifying as we accelerate new unit growth. Last week’s Fort Worth grand opening marked the first new restaurant of 2014 and our first location that was augmented with an engaging rooftop bar. The next phase of our growth is to open at least three more new restaurants in 2014, while continuing to find attractive locations for 2015 and beyond. We have made and will continue to make the necessary G&A investments to execute this plan and we remain on track to double our sales within five years.”

Fourth Quarter 2013 Financial Results

Restaurant sales in the fourth quarter of 2013 increased 6.4% to $24.5 million compared to $23.0 million in the fourth quarter of 2012. Excluding the effects of the Scottsdale, AZ and San Antonio, TX store remodels completed in November 2013, as well as the effect of the Chandler, AZ remodel completed in November 2012, same-store sales increased 3.5%, with guest traffic increasing 2.7% and guest check rising 0.8%. The 350 basis point increase laps a 10 basis point increase in the fourth quarter of 2012. The contribution from new restaurants to fourth quarter sales was $1.3 million.

Net loss in the fourth quarter of 2013 was $509,000, or $(0.06) per share, compared to net income of $851,000, or $0.10 per share, in the year-ago quarter. Net loss in the fourth quarter of 2013 included costs incurred for preopening, new restaurant and remodeling inefficiencies, and write-offs associated with the remodeled locations, which totaled approximately $0.20 per share.   

At December 31, 2013, cash and cash equivalents totaled $5.9 million compared to $8.0 million at December 31, 2012. Total debt was $3.5 million at December 31, 2013, compared to $0.4 million at December 31, 2012. The company has drawn $3.5 million against its line of credit as of year-end.

Full Year 2013 Financial Results

Restaurant sales in 2013 increased 2.3% to $98.3 million compared to $96.0 million in 2012. Same-store sales increased 1.4% due to higher pricing and a 20 basis point improvement in guest traffic in 2013, which laps a 2.7% same-store sales increase in 2012.

Net income for 2013 decreased to $2.7 million, or $0.31 per share, compared to net income of $4.8 million, or $0.54 per share in 2012, primarily driven by preopening costs for new restaurants and the infrastructure investments to support new unit growth.

Financial Guidance

For the first quarter of 2014, the company expects restaurant sales of $27.0 million, compared to $23.5 million in the same year-ago quarter, driven by a 3.0% same-store sales increase and an 11.0% operating week growth assumption. The company expects net income of $0.2 million, or $0.02 per share, which includes approximately $0.08 to $0.10 per share in costs associated with opening and operating new restaurants, higher corporate infrastructure investments and a timing shift in the company’s annual conference.

These statements relate to our future financial performance and growth goals for 2014, including but not limited to those relating to our sales trends and projected earnings for the first quarter of 2014 and expectations of new store openings in 2014 and beyond. We have attempted to identify these statements by using forward-looking terminology such as “may,” “will,” “anticipates,” “expects,” “believes,” “intends,” “should,” or comparable terms. All forward-looking statements included in this press release are based on information available to us on the date of this release and we assume no obligation to update these forward-looking statements for any reason.

Reconciliation of Restaurant Operating Profit to Income 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, preopening expense, insurance recoveries and other, and depreciation and amortization. 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 income 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 income from operations, the most comparable GAAP measure (in thousands).

Certain amounts do not sum to total due to rounding.
