Red Robin Gourmet Burgers Reports Restaurant Revenue Up 16% for the Fiscal First Quarter

Ended April 19, 2015

Greenwood Village, CO – May 19, 2015 – Red Robin Gourmet Burgers, Inc., (NASDAQ: RRGB), a casual dining restaurant chain serving an innovative selection of high-quality gourmet burgers in a family-friendly atmosphere, today reported financial results for the 16 weeks ended April 19, 2015.

First Quarter Financial Highlights


•	First quarter revenues were $394.9 million, an increase of 16.0% over the same period a year ago


•	Comparable restaurant revenue increased 3.1% over the same period a year ago


•	Restaurant-level operating profit, as a percent of restaurant revenue, increased to 23.0% from 22.4% in the same period a year ago (See Schedule II) benefiting approximately 80 basis points from lower health care and workers compensation costs


•	Earnings per diluted share increased 41.5% to $1.16 compared to $0.82 for the same period a year ago


•	Adjusted earnings per diluted share were $1.10, an increase of 34.1% compared to $0.82 for the same period a year ago (See Schedule I)

Net income increased 38.7% to $16.6 million compared to $11.9 million for the same period a year ago. Adjusted net income of $15.6 million excludes an after-tax adjustment for a change in accounting estimate for gift card breakage of $0.9 million or $0.06 per diluted share. See Schedule I for a reconciliation of adjusted net income and earnings per share.

“Our solid first quarter results are a testament to the excellent performance of our restaurant team members combined with Red Robin's food and beverage innovation,” said Steve Carley, Red Robin Gourmet Burgers, Inc. chief executive officer. “Our initiatives are enabling us to continue taking market share including our Brand Transformation remodels which are generating even stronger guest satisfaction scores.”

Operating Results

Total Company revenues, which include Company-owned restaurant revenue and franchise royalties, increased 16.0% to $394.9 million in the first quarter of 2015 from $340.5 million in the first quarter of 2014. New restaurant openings, including acquisitions and net of closures, contributed $43.5 million of additional revenue, comparable restaurant revenue increased $10.0 million, and other revenue increased $0.9 million. Other revenue included a one-time adjustment of $1.4 million related to a change in estimate of the redemption pattern over which gift card breakage revenue is recorded. This was partially offset by a $0.9 million decrease in franchise royalties related to 36 franchised restaurants that the Company acquired in 2014.

System-wide restaurant revenue (including franchised units) for the first quarter of 2015 totaled $488.1 million, compared to $455.7 million for the first quarter in 2014 at constant currency rates.

Comparable restaurant revenue increased 3.1% in the first quarter of 2015 compared to the prior year. In the first quarter, guest counts increased 1.1%, while average guest check increased 2.0%. Comparable restaurants are those Company-owned restaurants that have operated five full quarters during the period presented, and such restaurants are only included in the comparable metrics if they are comparable for the entirety of both periods presented.

Restaurant-level operating profit margin (a non-GAAP financial measure) was 23.0% in the first quarter of 2015 compared to 22.4% in the first quarter of fiscal year 2014, an improvement of 60 basis points. The improved margin resulted primarily from a 110 basis point decrease in labor costs driven by lower health insurance and workers' compensation claims partially offset by higher rent related to newly opened and acquired restaurants. Schedule II of this earnings release defines restaurant-level operating profit, discusses why it is a useful metric for investors, and reconciles this metric to income from operations and net income.

Other Results

Depreciation and amortization costs increased to $23.0 million in the first quarter of 2015 from $18.9 million in the first quarter of 2014. The increased depreciation was primarily related to new restaurants opened and acquired since the first quarter 2014 and restaurants remodeled under the Brand Transformation Initiative.

General and administrative costs were $35.0 million, or 8.9% of total revenues, compared to $32.1 million, or 9.4% of revenues a year ago. The increase of $2.9 million resulted primarily from increased compensation expense, hiring costs, and travel costs.

Selling expenses were $13.1 million, or 3.3% of revenue, in the first quarter of fiscal year 2015, compared to $10.3 million, or 3.0% of revenue, a year ago due to increased spending on media and costs associated with higher gift card sales.

Pre-opening costs were $1.0 million in the first quarter of fiscal year 2015, compared to $2.1 million a year ago. The decrease is due to fewer restaurant openings in 2015 in addition to $0.6 million in acquisition costs included in the first quarter of 2014.

The Company had an effective tax rate of 27.3% in the first quarter of fiscal year 2015, compared to a 27.0% rate in the same period a year ago.

Restaurant Development

As of the end of the first quarter of 2015, there were 408 Company-owned Red Robin^® restaurants, 10 Red Robin Burger Works^® and 99 franchised Red Robin restaurants for a total of 517 restaurants. In the first quarter of fiscal year 2015, the Company opened one Red Robin restaurant and three Red Robin Burger Works, and closed one Red Robin restaurant.

Under the Brand Transformation Initiative, the Company completed 18 remodels during the first quarter resulting in a total of 122 Red Robin restaurants remodeled to the new brand standards through the first quarter 2015.

Balance Sheet and Liquidity

As of April 19, 2015, the Company had cash and cash equivalents of $21.4 million and total debt of $144.2 million, including $8.3 million of capital lease liabilities. The Company decreased debt by $3.7 million during the first quarter.

Outlook for 2015

Red Robin’s 2015 fiscal year consists of 52 weeks and will end on December 27, 2015.

In fiscal year 2015, the Company expects total revenue growth of 12.0% to 12.5% including comparable restaurant revenue growth of 2.5% to 3.0%. Additionally, the Company plans to open 20 new Red Robin restaurants and five Red Robin Burger Works resulting in operating week growth, inclusive of 2014 acquisitions, of approximately 9.5%.

Capital investments in fiscal year 2015 are expected to be approximately $170 million. In addition to the new restaurant openings, the Company plans to relocate three locations and to remodel approximately 150 Red Robin restaurants as part of its Brand Transformation Initiative.

Restaurant-level operating profit margin in fiscal year 2015 is expected to approach 22.0%.

General and administrative costs are expected to be between $100 million and $101 million, while selling expenses are expected to be approximately 3.3% of sales. Pre-opening expense is expected to be approximately $7.5 million. Depreciation and amortization is projected to be between $78 million and $79 million.

Interest expense is expected to be approximately $4.0 million while the income tax rate in fiscal year 2015 is expected to be approximately 27.5%.

The sensitivity of the Company’s earnings per diluted share to a 1% change in guest counts for fiscal year 2015 is estimated to be $0.30 on an annualized basis. Additionally, a 10 basis point change in restaurant-level operating profit margin is expected to impact earnings per diluted share by approximately $0.07, and a change of approximately $145,000 in pre-tax income or expense is equivalent to approximately $0.01 per diluted share.

Schedule II

Reconciliation of Non-GAAP Restaurant-Level Operating Profit to Income

from Operations and Net Income

(In thousands)

The Company believes that restaurant-level operating profit is an important measure for management and investors because it is widely regarded in the restaurant industry as a useful metric by which to evaluate restaurant-level operating efficiency and performance. The Company defines restaurant-level operating profit to be restaurant revenue minus restaurant-level operating costs, excluding restaurant closures and impairment costs. The measure includes restaurant- level occupancy costs, which include fixed rents, percentage rents, common area maintenance charges, real estate and personal property taxes, general liability insurance, and other property costs, but excludes depreciation related to restaurant buildings and leasehold improvements. The measure excludes depreciation and amortization expense, substantially all of which is related to restaurant-level assets, because such expenses represent historical sunk costs which do not reflect current cash outlay for the restaurants. The measure also excludes selling, general, and administrative costs, and therefore excludes occupancy costs associated with selling, general, and administrative functions, and pre-opening costs. The Company excludes restaurant closure costs as they do not represent a component of the efficiency of continuing operations. Restaurant impairment costs are excluded, because, similar to depreciation and amortization, they represent a non-cash charge for the Company’s investment in its restaurants and not a component of the efficiency of restaurant operations. Restaurant-level operating profit is not a 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 or net income as indicators of financial performance. Restaurant-level operating profit as presented may not be comparable to other similarly titled measures of other companies. The table below sets forth certain unaudited information for the 16 weeks ended April 19, 2015 and the 16 weeks ended April 20, 2014, expressed as a percentage of total revenues, except for the components of restaurant-level operating profit, which are expressed as a percentage of restaurant revenue.

Certain percentage amounts in the table above do not total due to rounding as well as the fact that components of restaurant-level operating profit are expressed as a percentage of restaurant revenue and not total revenues.
