(1) Adjusted EBITDA, restaurant-level adjusted EBITDA, restaurant-level adjusted EBITDA margin, and adjusted net income are non-GAAP measures. For reconciliations of adjusted EBITDA, restaurant-level adjusted EBITDA, restaurant-level adjusted EBITDA margin, and adjusted net income to the most directly comparable GAAP measure see the accompanying financial tables. For definitions and a discussion of why we consider them useful, see “Non-GAAP Measures” below.

Management Commentary

“We’re pleased to report solid results for the first half of 2025, including the opening of our first restaurant in South Korea, ” said David Kim, Chairman and Chief Executive Officer of GEN. “This launch highlights our ability to expand in other parts of the world and bring our concept to the people of South Korea. Our results have been impressive, despite the current business environment including the implications of tariffs and the impact of immigration concerns creating continued economic headwinds. While our same store sales traffic was down in May and June, customers began to return in July. We expect these headwinds will primarily be absorbed through a combination of cost savings and operational efficiencies.

“Looking to the remainder of 2025, our development pipeline remains robust, and we are on pace to exceed our target of 12 to 13 new restaurants by the end of 2025 as we have 7 additional restaurants under development which we expect to complete construction by the end of 2025. We’re encouraged by the early success of our dual-concept of GEN Korean BBQ and Kan Sushi format as a potential lever for future growth. With strong cash flow and over $9.6 million in cash and cash equivalents, no material long-term debt, and full availability of our $20 million line of credit,

we are in an excellent position to execute our strategic priorities. With growing brand awareness, our strong restaurant return on investment, and disciplined execution, we remain confident in our ability to drive sustained, profitable growth in 2025 and beyond.”

(2) This is a forward-looking non-GAAP financial measure for which a reconciliation to the most directly comparable GAAP financial measure is not available without unreasonable efforts. Refer to “Forward-Looking Non-GAAP Financial Measures” in this release, which identifies the information that is unavailable without unreasonable efforts and provides additional information. It is probable that this forward-looking non-GAAP financial measure may be materially different from the corresponding GAAP financial measure.

Second Quarter 2025 Financial Results

Total revenue increased 2.2% to $55.0 million in the second quarter of 2025 compared to $53.9 million in the second quarter of 2024 as a result of 50 restaurants open in the three months ended June 30, 2025 compared to 40 restaurants open in the three months ended June 30, 2024.

Total restaurant operating expenses as a percentage of revenue increased 416 basis points to 91.7% in the second quarter of 2025 from 87.6% in the second quarter of 2024. Total restaurant operating expenses decreased 91 basis points compared to the first quarter of 2025. The year-over-year changes as a percentage of revenue are primarily driven by the following:

•Cost of goods sold increased by 97 basis points compared to the second quarter of 2024, primarily as a result of new start-up restaurants in operation and inflationary cost increases. There was minimal impact from the Company’s premium menu rollout.

•Payroll and benefits decreased 29 basis points compared to the second quarter of 2024. Payroll and benefits decreased 163 basis points compared to the first quarter of 2025 as the Company implements labor efficiencies.

•Occupancy costs increased 116 basis points compared to the second quarter of 2024, primarily due to new restaurant openings. Occupancy costs increased 42 basis points compared to the first quarter of 2025.

•Other operating costs increased by 78 basis points compared to the second quarter of 2024 and increased 39 basis points compared to the first quarter of 2025.

•Depreciation and amortization increased 87 basis points compared to the second quarter of 2024.

•Restaurant pre-opening expenses increased to $2.1 million for the second quarter of 2025 from $1.6 million in the second quarter of 2024 as we have 11 additional stores either opened or in the pipeline.

Loss from operations was $(1.9) million, or 3.4% of revenue, for the second quarter of 2025, compared to income from operations of $1.6 million, or 3,0% of revenue, for the second quarter of 2024. Restaurant-level adjusted EBITDA margin improved from 15.6% in the first quarter of 2025 to 16.3% for the second quarter of 2025.

General and administrative expenses totaled $6.4 million, or 11.6% of revenue, for the second quarter of 2025 and $5.1 million, or 9.4% of revenue, for the second quarter of 2024. Excluding non-cash stock compensation expenses of $0.7 million, general and administrative expenses for the second quarter of 2025 totaled $5.7 million, or 10.3% as a percentage of total revenue, largely reflecting increased personnel required for new restaurant development and additional marketing and legal expenditures. General and administrative expenses remained flat from the first quarter of 2025 to the second quarter of 2025.

Net loss before income taxes was $1.8 million, which equated to $0.05 per basic and diluted share of Class A common stock for the second quarter of 2025, compared to net income before income taxes of $2.1 million, which equates to $0.06 per diluted share of Class A common stock in the second quarter of 2024. The decrease was primarily attributable to higher costs related to new restaurant development, including pre-opening costs and increased occupancy expense for the ten additional stores opened during the second quarter of 2025. Adjusted net income was $1.2 million, which equated to $0.04 per diluted share of Class A common stock for the second quarter of 2025.

Adjusted EBITDA was $1.9 million or 3.4% of revenue for the second quarter of 2025, compared to $4.9 million or 9.1% of revenue in the prior year period.

As of June 30, 2025, the Company had $9.6 million in cash and cash equivalents. The Company continues to operate with no material long-term debt and has access to $20.0 million in total available liquidity.

Non-GAAP Measures

Restaurant-level adjusted EBITDA represents income (loss) from operations plus adjustments to add-back the following expenses: depreciation and amortization, pre-opening costs, general and administrative expenses, and non-cash lease expense. Restaurant-level adjusted EBITDA margin is the calculation of restaurant-level adjusted EBITDA divided by revenue. Management believes that restaurant-level adjusted EBITDA and restaurant-level adjusted EBITDA margin are useful to investors because these measures highlight trends in our core business that may not otherwise be apparent to investors when relying solely on GAAP financial measures and enabling investors to more effectively compare the Company’s performance to prior and future periods.

Adjusted EBITDA represents net income (loss) before net interest expense, income taxes, depreciation and amortization, stock-based compensation expense, employee retention credits, litigation accruals, non-cash lease expenses and non-cash lease expense related to pre-opening costs and gain on remeasurement of previously held interest. Adjusted EBITDA margin is defined as Adjusted EBITDA divided by revenue. Management believes that Adjusted EBITDA and Adjusted EBITDA margin are useful to investors because these measures highlight trends in our core business that may not otherwise be apparent to investors when relying solely on GAAP financial measures and enabling investors to more effectively compare the Company’s performance to prior and future periods.

Adjusted Net Income represents net (loss) income, adjusted for pre-opening costs, gain on remeasurement of previously held interest and non-cash stock-based compensation, and the related tax impact of the adjustments. Adjusted net income per share is defined as adjusted net income divided by the weighted-average number of shares of Class A common stock outstanding for the applicable period. Management believes that adjusted net income and adjusted net income per share are useful to investors because these measures highlight trends in our core business that may not otherwise be apparent to investors when relying solely on GAAP financial measures and enabling investors to more effectively compare the Company’s performance to prior and future periods.

Forward-Looking Non-GAAP Financial Measures

This press release also includes certain forward-looking non-GAAP financial measures for the year ending December 31, 2025. We calculate forward-looking non-GAAP financial measures based on internal forecasts that omit certain amounts that would be included in GAAP financial measures. We have not provided quantitative reconciliations of these forward-looking non-GAAP financial measures to the most directly comparable forward-looking GAAP financial measures because the excluded items are not available on a prospective basis without unreasonable efforts. For example, the timing of new restaurant openings and construction is difficult to predict because of delays in timing from city and other regulatory inspectors. In addition, we believe such reconciliations would imply a degree of precision and certainty that could be confusing to investors. It is probable that these forward-looking non-GAAP financial measures may be materially different from the corresponding GAAP financial measures
