Management Commentary

“Closing out 2024, we achieved our highest total annual revenue figure as a public company while maintaining healthy unit level economics as demonstrated by our results,” said David Kim, Chairman and Chief Executive Officer of GEN. “Driven by the success of new restaurants, for the year we delivered an impressive 15% increase in total revenue to $208.4 million, exceeding both our 2024 guidance and analysts’ expectations. We also achieved a restaurant-level adjusted EBITDA margin approaching 18%, which was in line with our 2024 outlook.

“Moving into 2025, our priority remains on executing our growth initiatives and capitalizing on the growing demand for Korean BBQ. We’re very pleased to report that our first quarter comparable restaurant sales through the end of February returned to positive growth of 1% as a result of continued success with our premium menu and modest pricing adjustments. We’ve opened three new restaurants in early 2025, with an additional 10-13 new units slated to open throughout the year. We’re also excited to bring GEN to the global stage as we plan to open at least two new restaurants in South Korea. Supported by over $23 million in cash and cash equivalents, strong cash flow from operations and no material long-term debt, we believe we’re well positioned to drive sustainable growth and profitability through execution of our strategic expansion strategy.”

Fourth Quarter 2024 Financial Results

Total revenue increased 21.2% to $54.7 million in the fourth quarter of 2024 compared to $45.1 million in the fourth quarter of 2023. Comparable restaurant sales decreased 4.8% in the fourth quarter of 2024 compared to the same period last year.

Total restaurant operating expenses (excluding pre-opening expenses) as a percentage of revenue decreased 58 basis points to 86.6% in the fourth quarter of 2024 from 87.2% in the fourth quarter of 2023. The year-over-year and quarter-over-quarter changes as a percentage of revenue are primarily driven by the following:

•Cost of goods sold increased by 146 basis points compared to the fourth quarter of 2023, largely due to a higher restaurant count and the premium menu.

•Payroll and benefits decreased 128 basis points compared to the fourth quarter of 2023.

•Occupancy costs increased 27 basis points compared to the fourth quarter of 2023, largely due to the six new restaurant openings over the last twelve months.

•Other operating costs decreased by 137 basis points compared to the fourth quarter of 2023.

•Depreciation and amortization increased 34 basis points compared to the fourth quarter of 2023.

•Restaurant pre-opening expenses increased to $2.3 million for the fourth quarter of 2024 from $1.6 million in the fourth quarter of 2023 due to additional new restaurant openings compared to the year ago period.

General and administrative expenses increased to $5.6 million, or 10.3% as a percentage of total revenue, excluding non-cash stock compensation expense, for the fourth quarter of 2024, primarily due to additional personnel required for new restaurant development.

Net loss before income taxes was $1.2 million, which equated to $(0.04) per diluted share of Class A common stock for the fourth quarter of 2024, compared to $(0.3) million, which equated to $(0.01) per diluted share of Class A common stock in the fourth quarter of 2023. The decrease was largely due to higher expenses related to new restaurant development, including pre-opening costs. Adjusted net loss was $0.7 million, which equated to $(0.02) per diluted share of Class A common stock for the fourth quarter of 2024.

Adjusted EBITDA increased 25.0% to $2.1 million or 3.8% of revenue inclusive of pre-opening expense of approximately $1.6 million for the fourth quarter of 2024, compared to $1.6 million or 3.6% of revenue inclusive of pre-opening expenses of $1.2 million in the prior year period.

2024 Financial Results

Revenue increased 15.1% to $208.4 million in 2024 compared to $181.0 million in 2023. Comparable restaurant sales decreased 5.6% in 2024 compared to 2023.

Total restaurant operating expenses before pre-opening expenses as a percentage of revenue increased 146 basis points to 85.8% in 2024 from 84.4% in 2023 primarily driven by the following:

•Cost of goods sold increased 76 basis points primarily due to higher costs associated with the launch of the premium menu and increased restaurant count.

•Payroll and benefits decreased 56 basis points.

•Occupancy costs increased 31 basis points primarily due to the six new restaurants opened in the past twelve months.

•Other operating costs increased 37 basis points.

•Depreciation and amortization increased 58 basis points.

•Restaurant pre-opening expenses increased to $7.6 million for 2024 from $3.7 million in 2023 due to a higher volume of new store openings.

General and administrative expenses excluding non-cash stock compensation expense increased year-over-year to $18.3 million in 2024 compared to $12.6 million in 2023, which included management fees. As a percentage of revenues, general and administrative expenses excluding non-cash stock compensation expense were approximately 8.8% in 2024. The increase is primarily attributable to additional fees for consulting and management following the Company’s IPO in 2023 as well as additional personnel required for new restaurant development.

Net income before income taxes was $4.9 million, which equated to $0.13 per diluted share of Class A common stock, compared to $11.5 million, which equated to $0.08 per diluted share of Class A common stock in 2023. The decrease is largely due to increased expenses from restaurant development. Adjusted net income, which represents net income plus non-cash stock-based compensation, was $7.4 million, which equated to $0.21 per diluted share of Class A common stock for 2024.

Adjusted EBITDA was $16.7 million and 8.0% of revenue inclusive of pre-opening expense of approximately $5.3 million, compared to $18.8 million and 10.4% of revenue inclusive of pre-opening expense of approximately $2.6 million in 2023. Without pre-opening expense, adjusted EBITDA was $22.0 million for 2024.

As of December 31, 2024, the Company had $23.7 million in cash and cash equivalents. The Company continues to operate with no long-term debt, aside from approximately $4.3 million in government-funded EIDL loans, and has access to $40.7 million in total available liquidity, plus annual cash flow from operations of approximately $20 million.

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, related party consulting fees, management fees and non-cash lease expense. Management believes that restaurant-level adjusted EBITDA is useful to investors because this measure highlights 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, and consulting fees paid to a related party and we also exclude non-recurring items, such as stock-based compensation expense, gain on extinguishment of debt, and Restaurant Revitalization Fund, or RRF, grants, employee retention credits, litigation accruals, aborted deferred IPO costs written off, non-cash lease expenses and non-cash lease expense related to pre-opening costs. Management believes that restaurant-level adjusted EBITDA is useful to investors because this measure highlights 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 income plus non-cash stock-based compensation net of the tax impact. Management believes that adjusted net income is useful to investors because this measure highlights 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.
