Exhibit 99.1

Red Robin Gourmet Burgers, Inc. Reports Results for the Fiscal First Quarter Ended April 19, 2026

Englewood, CO – May 19, 2026 – Red Robin Gourmet Burgers, Inc. (NASDAQ: RRGB) ("Red Robin" or the "Company"), 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 fiscal first quarter ended April 19, 2026.

Chief Executive Officer Comments

“During the first quarter of 2026, we delivered continued progress in traffic trends and restaurant-level profitability at levels we haven’t achieved in several years, reflecting the growing momentum behind our First Choice strategic plan,” said Dave Pace, Red Robin’s President and Chief Executive Officer.

“This performance was driven by the successful launch of our new menu, which reflects a sharper focus on innovation, craveability, and value, along with targeted marketing investments that amplified awareness of our Big Yummm value platform and strengthened guest engagement through more personalized outreach. At the same time, we continued to improve restaurant operations by driving labor efficiencies, simplifying execution, and empowering our Managing Partners to deliver a better overall guest experience.”

First Quarter 2026 Financial Summary:

The following table presents financial results for the fiscal first quarter 2026, compared to results from the same period in 2025 ($ in millions except per share data):

Sixteen Weeks Ended

April 19, 2026 April 20, 2025

Total revenues $ 378.3  $ 392.4

Restaurant revenues $ 371.1  $ 385.8

(0.6) % 3.2  %

Income (loss) from operations $ 5.5  $ 9.1

$ 54.8  $ 55.0

Net income (loss) per share - diluted

$ (0.12) $ 0.07

Adjusted net income (loss) per share - diluted(2)

$ 0.13  $ 0.19

(1)    Comparable restaurant revenue represents revenue from Company-owned restaurants that have operated for at least 18 months as of the beginning of the period presented, excluding the impact of deferred loyalty revenue.

(2)    See "Reconciliation of Non-GAAP Results to GAAP Results" for more details.

First Quarter 2026 Commentary

•Comparable restaurant revenue decreased 0.6%. This included a 1.6% decrease in guest traffic, and a 1.0% increase in average guest check.

•Restaurant level operating profit margin of 14.8%, a 50 basis point improvement from the first quarter of 2025. This improvement was primarily driven by higher average guest check and the benefits of efficiency initiatives offsetting the impact of inflation and lower guest traffic.

•Adjusted EBITDA of $27.3 million, a 2.1% decrease from the first quarter of 2025. This decrease was driven by increased marketing costs, partially offset by general and administrative efficiencies.

Balance Sheet and Liquidity

As of April 19, 2026, the Company had outstanding borrowings under its credit facility of $175.7 million and liquidity of approximately $40.8 million, including cash and cash equivalents and available borrowing capacity under its credit facility.

Outlook for Fiscal 2026 and Guidance Policy

The Company is reaffirming its previously issued fiscal 2026 guidance, presented below. The projections are as of this date and the Company assumes no obligation to update or supplement this information.

•Comparable Restaurant Revenue growth, excluding deferred loyalty revenue, of 0.5% to 1.5%;

•Restaurant level operating profit of approximately 13.0%;

•Adjusted EBITDA of $70 million to $73 million;

•Capital expenditures of $25 million to $30 million.

Providing income (loss) from operations and net income (loss) guidance is potentially misleading and not practical given the difficulty of projecting event-driven transactional and other non-core operating items. As such, we do not present a reconciliation of forecasted non-GAAP measures to the corresponding GAAP measures.

Reconciliation of Non-GAAP Results to GAAP Results

In addition to the results provided in accordance with accounting principles generally accepted in the United States of America ("GAAP") throughout this press release, the Company has provided certain non-GAAP measures, which present operating results on an adjusted basis. These are supplemental measures of performance that are not required by or presented in accordance with GAAP and include the following: (i) Restaurant level operating profit, (ii) net income (loss) before interest expense, income taxes, and depreciation and amortization ("EBITDA"), (iii) adjusted EBITDA, and (iv) adjusted net income (loss) and adjusted net income per share - diluted.

We believe that our use of non-GAAP financial measures permits investors to assess the operating performance of our business relative to our performance based on GAAP results and relative to other companies within the restaurant industry by isolating the effects of certain items that may vary from period to period without correlation to core operating performance or that vary widely among similar companies. Management believes this supplemental information will assist with comparisons of past and future financial results against the present financial results presented herein.

Restaurant Level Operating Profit

The Company believes 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 income from operations less franchise revenue and other revenue, plus other (gains) charges, net, selling, general and administrative, and depreciation and amortization. The measure includes restaurant level occupancy costs that 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 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 costs associated with selling, general and administrative functions, as well as other (gains) charges, net because these costs are non-operating and therefore not related to the ongoing operations of its restaurants. Restaurant level operating profit is not a measurement determined in accordance with GAAP and should not be considered in isolation, or as an alternative, to income (loss) from operations as an indicator of financial performance. Restaurant level operating profit as presented may not be comparable to other similarly titled measures of other companies in the Company's industry.

The following table reconciles income (loss) from operations to restaurant level operating profit in thousands and in percent of total revenue for the period presented:

Sixteen Weeks Ended

Income (loss) from operations as a percentage of total revenues 1.5  % 2.3  %

Restaurant level operating profit margin (as a percentage of restaurant revenue) 14.8  % 14.3  %

EBITDA and Adjusted EBITDA

We define EBITDA as net income (loss) before interest expense, income taxes, and depreciation and amortization. Adjusted EBITDA is EBITDA, further adjusted to exclude the impact of non-operating items including changes in estimates, asset impairments, litigation contingencies, gains (losses) on debt extinguishment, restaurant and office closure costs, gains (losses) on restaurant sales, severance and executive transition costs, stock-based compensation expense and other non-cash or discrete items. EBITDA and adjusted EBITDA are supplemental measures of our performance that we believe gives the reader additional insight into the ongoing operational results of the Company.

The following table reconciles net income (loss) to adjusted EBITDA in thousands for the period presented:

(2)    Consisted of compensation expense associated with stock-based awards including phantom awards that may be settled in stock or cash at the Company’s option and stock appreciation rights, which are settled in cash.

Adjusted Net Income (loss) Per Diluted Share

We define adjusted net income (loss) per diluted share as net income (loss) excluding the impact of non-operating items including changes in estimates, asset impairments, litigation contingencies, gains (losses) on debt extinguishment, restaurant and office closure costs, gains (losses) on restaurant sales, severance and executive transition costs, stock-based compensation expense and other non-cash or discrete items; net of income tax impacts. Adjusted net income (loss) per share - diluted is a supplemental measure of our performance that we believe gives the reader additional insight into the ongoing operational results of the Company.

(2)    Assumed a 26% income tax rate, representing a blended average of federal and state statutory rates.

(3)    Dilutive securities were included in the computation of adjusted net income (loss) per share - diluted for the sixteen weeks ended April 19, 2026, because the Company reported an adjusted net income for the period. This differs from the GAAP net income (loss) per share - diluted calculation seen on the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) as the Company reported a net loss for the sixteen weeks ended April 19, 2026.
