Strategic Portfolio Optimization Creating Long-Term Value

Cost Management Drives Restaurant Margin Improvement in Fourth Quarter

Full Year 2026 Financial Targets Introduced

The ONE Group Hospitality, Inc. (“The ONE Group” or the “Company”) (Nasdaq: STKS) today reported its financial results for the fourth quarter and full year ended December 28, 2025.

Effective January 1, 2025, the Company adopted a new fiscal calendar structure using four 13-week quarters, with a 53rd week added when necessary. The 2025 fiscal year ran from January 1, 2025, to December 28, 2025.

This fiscal calendar change created timing differences that impacted quarterly comparisons: the fourth quarter of 2025 had 91 days versus 92 days in the fourth quarter of 2024. Additionally, the New Year’s Eve holiday shifted from fiscal 2025 to fiscal 2026. The exclusion of New Year’s Eve in the current year impacted total GAAP revenues by approximately 2.5%, representing 37% of the total GAAP revenue decline for the quarter.

Highlights for the fourth quarter 2025 compared to the same quarter in 2024 are as follows:

• Total GAAP revenues decreased 6.7% to $207 million from $222 million;
• Consolidated comparable sales* decreased 1.8%;
• GAAP net loss attributable to The ONE Group Hospitality, Inc. increased to $6 million from a net income of $2 million primarily related to a non-cash loss on impairment of $7 million related to the Grill optimization strategy;
• Restaurant Operating Profit** increased by 10 basis points to 19.5% of owned restaurant net revenue, excluding Grill Concepts restaurants closed or to be closed, from 19.4%; and,
• Adjusted EBITDA*** attributable to The ONE Group Hospitality, Inc. decreased to $28 million from $31 million, with approximately $3 million of the decrease attributable to the New Year’s Eve holiday shift from fiscal 2025 to fiscal 2026.

Highlights for the full year 2025 compared to the full year 2024 are as follows:

• Total GAAP revenues increased 19.7% to $806 million from $673 million;
• Consolidated comparable sales* decreased 3.7%;
• GAAP net loss attributable to The ONE Group Hospitality, Inc. increased to $92 million from a net loss of $17 million due primarily to an increase in the income tax expenses of $69 million, primarily related to the establishment of a non-cash tax valuation allowance, and non-cash lease termination and exits costs of $7 million coupled with a non-cash impairment of $11 million related to the Grill optimization strategy;
• Adjusted Operating Income**** increased 15.2% to $38 million from $33 million; and,
• Adjusted EBITDA*** attributable to The ONE Group Hospitality, Inc. increased 16.3% to $89 million, excluding approximately $4 million attributable to two days in fiscal year 2025 versus fiscal year 2024, from $76 million.

“Guests continue to choose our differentiated Vibe Dining concepts when they want memorable experiences. In the fourth quarter, consolidated comparable sales improved by four percentage points sequentially from the third quarter, with every brand contributing. So far in the first quarter, we are delivering positive consolidated comparable sales. These results confirm that our strategy is working, even in a challenging consumer environment,” said Emanuel “Manny” Hilario, President and CEO of The ONE Group.

“Our disciplined cost management initiatives continue to drive results. In the fourth quarter, we expanded our restaurant operating margins, even while facing sales deleveraging. Looking ahead, our operational foundation remains strong, supported by beef supply and pricing secured through September 2026 and significant cost synergies from the Benihana acquisition that we believe we have yet to fully capture,” Hilario continued.

“In 2025, we took decisive action to optimize our portfolio and position the company for sustained long-term growth. We closed six underperforming Grill locations and identified up to five additional units for conversion to our higher-performing Benihana or STK formats through 2026. Our first RA Sushi to STK conversion in Scottsdale, Arizona has exceeded expectations, operating at a run rate of approximately $7 million in annualized sales on an approximate $1 million capital investment. This validates the strength of this repositioning strategy. Additionally, we advanced our asset-light growth strategy by securing development rights for ten Benihana and Benihana Express locations in the San Francisco Bay Area, representing the largest franchise agreement in our Company's history. We have also secured a commitment for an additional franchised Benihana location and a licensed Benihana Express location in the Florida Keys,” Hilario concluded.

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.

We exclude items management does not consider in the evaluation of its ongoing core operating performance from Adjusted EBITDA. Starting in Q4 2025, the Adjusted EBITDA attributable to closed Grill Concepts restaurants is excluded from Adjusted EBITDA. 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.

The following table sets forth certain statements of operations data as a percentage of total revenues for the periods indicated. Certain percentage amounts may not sum to total due to rounding.

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 Operating Income, 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 at these locations. 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):

The following table presents the elements of the quarterly and annual Same Store Sales measure for 2025:

Adjusted Operating Income. We define Adjusted Operating Income as operating income (loss) before transition and integration expenses, loss on impairment of non-current assets, lease termination and exit expenses and transaction and exit costs. Not all the aforementioned items defining Adjusted Operating Income occur in each reporting period but have been included in our definitions of terms based on our historical activity. Adjusted Operating Income 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.

Adjusted EBITDA. We define Adjusted EBITDA as net income (loss) before interest expense, provision for income taxes, depreciation and amortization, stock-based compensation, transition and integration expenses, loss on impairment of non-current assets, lease termination and exit expenses, transaction and exit costs, loss on early debt extinguishment, non-cash rent and the Adjusted EBITDA attributable to the closed Grill Concepts restaurants. 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. Refer to the reconciliation of Net income (loss) to Adjusted EBITDA in this press release.

On January 1, 2025, the Company transitioned from a calendar-based fiscal year to a 52/53-week fiscal year. Beginning in 2025, the Company’s fiscal year ended on the last Sunday in December. The Company’s fiscal year ending December 28, 2025 contained 362 days due to the transition. The following unaudited pro forma results of operations for December 28, 2025 have been adjusted to reflect a 364-day year (in thousands):

The following table presents a reconciliation of Owned restaurant net revenue to Owned restaurant net revenue, excluding net revenue of Grill Concepts restaurants closed prior to December 28, 2025 or to be closed in the first quarter of 2026 for the periods indicated (in thousands):

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.

The following table presents a reconciliation of Operating income to Restaurant Operating Profit and Restaurant EBITDA for the periods indicated (in thousands):

Restaurant Operating Profit by brand is as follows (in thousands):
