GEN Restaurant Group Reports Second Financial Results

CPG Momentum Accelerates with Purchase Commitments from More Than 100 Costco Warehouses Nationwide and New Distribution Agreements with United Natural Foods and C&S Wholesale Grocers; Second Quarter Revenue Increased 1.2% Year-Over-Year to $55.7 Million

CERRITOS, CA, August 10, 2026 - GEN Restaurant Group, Inc. (“GEN” or the “Company”) (Nasdaq: GENK), a leader in Korean BBQ both in-restaurant and at home, with 54 GEN Korean BBQ locations and a rapidly growing consumer packaged goods (“CPG”) business, today announced its financial results for the second quarter ended June 30, 2026

Financial Summary:

Second Quarter 2026 Financial and Recent Operational Highlights

Management Commentary

David Kim, Chairman and Chief Executive Officer of GEN, commented: "The defining development of the second quarter was the strategic path it set for GEN. Earlier today, we announced receipt of a non-binding letter of intent from a nationwide, multi-concept restaurant operator to acquire our U.S. restaurant operations, with GEN retaining 100% of its rapidly growing consumer packaged goods and retail business. Our Board of Directors, together with our financial and legal advisors, is carefully reviewing and evaluating the proposal. The letter of intent is non-binding and no assurance can be given that any transaction will result, but we believe a transaction of this nature could make strategic sense — pairing our restaurants with a proven operator equipped to scale them, positioning GEN as a pure-play CPG company, and allowing us to dedicate our people and our capital fully to CPG — the fastest-growing part of the K-Food platform we are building.

"Our confidence in CPG is grounded in the momentum of our retail business, where GEN products are now in nearly 2,000 retail doors nationwide. Our CPG division delivered its best quarter yet, with revenue up 341% sequentially, and June was our largest month to date, with revenue surpassing $2 million. In June alone, we secured purchase commitments from approximately 60 to 70 Costco Warehouses across the Pacific Northwest — bringing our total to more than 100 warehouses, or over 16% of Costco's domestic footprint — signed national distribution agreements with C&S Wholesale Grocers and UNFI, and added new retail banners nationwide. Each win builds on the same formula: authentic GEN Korean BBQ flavors, retail-ready packaging, and in-store demos run by our own trained staff, which continue to deliver sell-through well above typical third-party programs. More than 1,000 additional doors have been presented to buyers, and more than 8,000 further doors are in active outreach across grocery and mass retail.

"On execution: we already purchase nearly $40 million of meat a year for our restaurants, so the procurement scale, supplier relationships, and buying power that CPG requires are already built. We are not standing up a supply chain from zero; we are pointing an existing one at the freezer aisle. And to stay ahead of demand, we have secured additional manufacturing capacity domestically and in South Korea.

"Total revenue for the second quarter of 2026 increased 1.2% year-over-year to $55.7 million — a return to revenue growth following a 6.0% year-over-year decline in the first quarter of 2026. Within the restaurants, payroll and benefits improved approximately 200 basis points as a percentage of revenue, and we exited six underperforming locations during the quarter, four of which were transferred to our previously announced joint venture with Chubby Cattle, in which we retained a 49% interest. These exits are expected to further strengthen restaurant-level performance beginning in the third quarter.

"As Korean food continues to move firmly into the American mainstream, GEN has built the brand, the products and the retail relationships to meet that demand at scale," concluded Kim.

Second Quarter 2026 Financial Results

Total revenue increased by 1.2% to $55.7 million in the second quarter of 2026 compared to $55.0 million in the second quarter of 2025. Growth in the Company's CPG division and revenue from restaurants opened in 2025 and 2026 more than offset a 9.3% decline in comparable restaurant sales and the loss of revenue from the six restaurants exited during the quarter, which contributed $2.3 million of revenue in the second quarter of 2025.

Total restaurant operating expenses were 95.4% of revenue in the second quarter of 2026, as compared to 91.7% of revenue in the second quarter of 2025. The year-over-year change as a percentage of revenue was driven by higher commodity costs and the growing mix of CPG revenue, which carries retail cost of goods, partially offset primarily by the growing mix of CPG revenue, which carries retail cost of goods and accounted for 81% of the $3.2 million year-over-year increase in food costs, with the balance reflecting commodity cost inflation in the Company’s restaurants, partially offset by lower payroll and benefits expenses and lower pre-opening expenses ($1.3 million versus $2.1 million in the prior-year period).

Loss from operations was $(5.2) million, or (9.2)% of revenue, for the second quarter of 2026, as compared to a loss from operations of $(1.9) million, or (3.4)% of revenue, for the second quarter of 2025. Restaurant-level adjusted EBITDA was $6.3 million, or 11.3% of revenue, for the second quarter of 2026, as compared to $9.0 million, or 16.3% of revenue, for the second quarter of 2025. Restaurant-level adjusted EBITDA margin improved sequentially from 7.4% in the first quarter of 2026 and 7.9% in the fourth quarter of 2025, representing the Company’s strongest restaurant-level margin in three quarters, reflecting labor efficiencies and the exit of underperforming locations.

General and administrative expenses totaled $7.1 million, or 12.8% of revenue, for the second quarter of 2026, as compared to $6.4 million, or 11.6% of revenue, for the second quarter of 2025. The increase was attributable to investment in the Company’s CPG go-to-market, including marketing and in-store demonstrations; excluding CPG, corporate and restaurant general and administrative expenses declined year over year. The Company recognized a $0.6 million loss on lease termination in the second quarter of 2026 related to the closure of two locations in Korea, with no comparable amount in the prior-year period.

Net loss was $(4.6) million, which equates to $(0.14) per basic and diluted share of Class A common stock, for the second quarter of 2026, as compared to a net loss of $1.7 million, or $(0.05) per basic and diluted share of Class A common stock, in the second quarter of 2025.

Adjusted EBITDA was negative $41,000 for the second quarter of 2026, as compared to $1.9 million, or 3.4% of revenue, in the prior-year period.

Cash and cash equivalents were $5.9 million as of June 30, 2026, as compared to $2.8 million as of December 31, 2025. Total debt outstanding totaled $24.0 million, as compared to $14.6 million as of December 31, 2025.

Non-GAAP Measures

Restaurant-level adjusted EBITDA represents (loss) income from operations plus adjustments for the following items: depreciation and amortization, pre-opening costs, loss on lease termination, gain on deconsolidation of restaurants, general and administrative expenses, and non-cash lease expense. Non-cash items such as charges for asset impairment and asset disposals are not included in the restaurant-level adjusted EBITDA. 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 (loss) income excluding interest (expense) income, net, income taxes, depreciation and amortization, stock-based compensation, employee retention credits, litigation accrual for a discrete claim, loss on lease termination, gain on deconsolidation of restaurants, non-cash lease expenses and non-cash lease expense included in pre-opening costs. 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 (Loss) Income represents net (loss) income, adjusted for pre-opening costs, non-cash stock-based compensation, legal settlements, loss on lease termination, gain on deconsolidation of restaurants, and the related tax impact of the adjustments. Adjusted net (loss) income per share is defined as adjusted net (loss) income divided by the weighted-average number of shares of Class A common stock outstanding for the applicable period. Management believes that adjusted net (loss) income and adjusted net (loss) 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.
