The ONE Group Reports Second Quarter 2026 Financial Results

Positive Comparable Sales, Positive Transactions Across All Business Segments

Capital Expenditures, Net of Tenant Improvement Allowances, Reduced 38% Year-Over-Year as Company Prioritizes Capital-Efficient Growth and Free Cash Flow Generation

Denver, CO(BUSINESS WIRE) – August 5, 2026 – The ONE Group Hospitality, Inc. (“The ONE Group” or the “Company”) (Nasdaq: STKS) today reported its financial results for the second quarter ended June 28, 2026.

Highlights for the second quarter 2026 compared to the same quarter in 2025 are as follows:

Total GAAP revenues decreased 3.3% to $200.5 million from $207.4 million, due to the impact of permanent and temporary restaurant closures
Consolidated comparable sales* increased 0.9%
GAAP operating income increased to $6.6 million from $0.7 million
Restaurant operating profit** increased by 110 basis points to 16.4% of owned restaurant net revenue from 15.3%
Year-to-date net cash provided by operating activities improved $21.7 million to $33.0 million from $11.3 million

“Our second quarter results underscore the momentum we are building across the portfolio, driven by the continued strength of our Vibe Dining brands. Consolidated comparable sales were positive, with positive transaction growth across all segments. STK posted a strong comparable sales performance of 3.2%. We completed the relocation of our STK Downtown New York restaurant from Little West 12th to 15th Street, with the restaurant having been closed for most of the second quarter due to the transition,” said Emanuel “Manny” Hilario, President and CEO of The ONE Group.

“Quarterly margin performance was strong, with the consolidated margin expanding 110 basis points to 16.4%. These results reflect the continued execution of our operational and strategic initiatives across the portfolio,” Hilario continued.

“We remain focused on capital-efficient growth and portfolio optimization. During the quarter, we signed a new development agreement for two licensed STK locations at a major U.S. airport. We are also very excited about the expansion of the Benihana Express brand, a small footprint, fast casual version of the Benihana that you crave. Both of these are great examples of our asset-light strategy in action, which continues to gain traction with additional openings planned for the second half of the year. With this approach, we will be able to reduce capital expenditures while sustaining our development pipeline, further strengthening our balance sheet. Going forward, we remain committed to disciplined capital allocation and operational excellence as the foundation for building long-term shareholder value,” Hilario concluded.

Grill Concepts Portfolio Optimization

Temporarily closed three Kona Grill restaurants and two RA restaurants in January 2026 for conversion to Benihana or STK formats
The conversion of the Riverton Kona Grill to Benihana was completed on July 31, 2026 and is now re-opened to the public
The Kona Grill Baltimore conversion is expected to re-open as an STK in the third quarter
Conversion economics: approximately $1.0 to $1.5 million, net build-out cost per conversion with a one-year payback
Expected outcome: 100% profitable Grill portfolio with enhanced margins

Capital Efficiency Focus

Significant reduction in discretionary capital expenditures to increase free cash flow to strengthen the balance sheet
Prioritizing asset-light and conversion-driven growth with emphasis on franchising and licensing opportunities

(1) We have not reconciled guidance for Consolidated Adjusted EBITDA to the corresponding GAAP financial measure because we do not provide guidance for the various reconciling items. We are unable to provide guidance for these reconciling items because we cannot determine their probable significance, as certain items are outside of our control and cannot be reasonably predicted since these items could vary significantly from period to period. Accordingly, reconciliations to the corresponding GAAP financial measure are not available without unreasonable effort.

Non-GAAP Definitions

We have evolved our definition of non-GAAP financial measures starting in Q4 2025. We use certain non-GAAP measures in analyzing operating performance and believe that the presentation of these measures provides investors and analysts with information that is beneficial to gaining an understanding of the Company's financial results. Non-GAAP disclosures should not be viewed as a substitute for financial results determined in accordance with GAAP.

Reconciliations of these non-GAAP measures are included under “Reconciliation of Non-GAAP Measures” in this press release.

* Comparable sales represent total U.S. food and beverage sales at owned and managed units, a non-GAAP financial measure, opened for at least a full 24-months. This measure includes total revenue from our owned and managed locations. The Company monitors sales growth at its established restaurant base in addition to growth that results from restaurant acquisitions and new restaurant openings. Refer to the reconciliation of GAAP revenue to total food and beverage sales at owned and managed units in this press release.

** We define Restaurant operating profit as owned restaurant net revenue minus owned restaurant cost of sales and owned restaurant operating expenses. Restaurant operating profit has been presented in this press release and is a supplemental measure of financial performance that is not required by, or presented in accordance with, GAAP. Refer to the reconciliation of operating income to Restaurant operating profit in this press release.

Reconciliation of Non-GAAP Measures

We prepare our financial statements in accordance with generally accepted accounting principles (GAAP). In this press release, we also make references to the following non-GAAP financial measures: total food and beverage sales at owned and managed units, Adjusted EBITDA, Restaurant operating profit and Restaurant EBITDA.

Total food and beverage sales at owned and managed units. Total food and beverage sales at owned and managed units represents our total revenue from our owned operations as well as the revenue reported to us with respect to sales at our managed locations, where we earn management and incentive fees. We believe that this measure represents a useful internal measure of performance as it identifies total sales associated with our brands and hospitality services that we provide. Accordingly, we include this non-GAAP measure so that investors can review financial data that management uses in evaluating performance, and we believe that it will assist the investment community in assessing performance of restaurants and other services we operate, whether or not the operation is owned by us. However, because this measure is not determined in accordance with GAAP, it is susceptible to varying calculations and not all companies calculate these measures in the same manner. As a result, this measure as presented may not be directly comparable to a similarly titled measure presented by other companies. This non-GAAP measure is presented as supplemental information and not as an alternative to any GAAP measurements. The following table includes a reconciliation of our GAAP revenue to total food and beverage sales at our owned and managed units (in thousands):

Adjusted EBITDA. We define Adjusted EBITDA as net (loss) income before interest expense, provision for income taxes, depreciation and amortization, stock-based compensation, lease termination and restaurant closure expenses, transition and integration expenses, transaction costs, non-cash rent, non-cash impairment loss, non-recurring gains and losses, certain transactional and exit costs, and loss on early debt extinguishment. Not all the aforementioned items defining Adjusted EBITDA occur in each reporting period but have been included in our definitions of terms based on our historical activity. Adjusted EBITDA has been presented in this press release and is a supplemental measure of financial performance that is not required by, or presented in accordance with, GAAP.

(1)Lease termination and restaurant closure expenses are costs associated with closed locations.
(2)Non-cash rent expense is included in owned restaurant operating expenses, pre-opening expenses and general and administrative expense on the condensed consolidated statements of operations.

Restaurant operating profit and Restaurant EBITDA. We define Restaurant operating profit as owned restaurant net revenue minus owned restaurant cost of sales and owned restaurant operating expenses. We define Restaurant EBITDA as Restaurant operating profit minus non-cash rent.

We believe Restaurant operating profit and Restaurant EBITDA are an important component of financial results because: (i) they are widely used metrics within the restaurant industry to evaluate restaurant-level productivity, efficiency, and performance, and (ii) we use Restaurant operating profit and Restaurant EBITDA as key metrics to evaluate our restaurant financial performance compared to our competitors. We use these metrics to facilitate a comparison of our operating performance on a consistent basis from period to period, to analyze the factors and trends affecting our business and to evaluate the performance of our restaurants.
