(1) Adjustments include the following assumptions used to calculate the fair value of the awards at each valuation date in accordance with Topic 718: •For awards of time-based RSUs, adjustments reflected are based on the fair value of the awards as of the applicable valuation date calculated by multiplying the change in stock price at each fiscal year end presented by the number of shares of restricted stock outstanding on such valuation date. •For the performance-based RSUs, adjustments reflected are based on the fair value of the awards as of the applicable valuation date calculated by multiplying the stock price at each fiscal year end by the number of performance-based RSUs outstanding and by the estimated probability of achieving the performance target that was used to calculate our Topic 718 expense for each fiscal year. •Discussion of the assumptions used in calculating the grant date fair value of the RSUs is set forth in Note 10 of the Notes to Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 29, 2024 filed with the SEC on February 26, 2025. |  |  |  |

Additional 402(v) Disclosure | The amounts reported in the “Compensation Actually Paid to PEO” and “Average Compensation Actually Paid to Non-PEO NEOs” columns do not reflect the actual compensation paid to or realized by our PEO or our non-PEO NEOs during each applicable year. The calculation of compensation actually paid for purposes of this table includes point-in-time fair values of stock awards and these values will fluctuate based on our stock price, various accounting valuation assumptions and projected performance related to our performance awards. See the Summary Compensation Table for certain other compensation of our PEO and our non-PEO NEOs for each applicable fiscal year and the Options Exercised and Stock Vested table for the value realized by each of them upon the vesting of stock awards during 2024. Relationship Between Financial Performance Measures The graphs below compare the compensation actually paid to our PEO and the average of the compensation actually paid to our remaining NEOs, with (i) our cumulative TSR, (ii) our Peer Group TSR, (iii) our net income(loss), and (iv) our Adjusted EBITDA, in each case, for the fiscal years 2020, 2021, 2022, 2023, and 2024. TSR amounts reported in the graph assume an initial fixed investment of $100, and that all dividends, if any, were reinvested. |  |  |  |

Non-GAAP Measure Description | (3) Adjusted EBITDA is a non-GAAP measure and should not be considered in isolation or as a substitution for financial information provided in accordance with GAAP. This non-GAAP financial measure may not be computed in the same manner as similarly titled measures used by other companies. The Company expects to continue to incur expenses similar to the Adjusted EBITDA financial adjustments described, and investors should not infer from the Company’s presentation of this non-GAAP financial measure that these costs are unusual, infrequent, or non-recurring. Adjusted EBITDA is a non-GAAP measure. A definition of Adjusted EBITDA, and a reconciliation of Adjusted EBITDA to the nearest GAAP counterpart, is provided in Annex A. |  |  |  |
