The dollar amounts do not reflect the actual amount of compensation earned or received during the applicable fiscal year. There are no material differences between the assumptions used to compute the valuation of the equity awards for calculating the compensation actually paid from the assumptions used to compute the valuation of such equity awards as of the grant date. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to the total compensation of our PEO and non-PEO NEOs for each year to determine the “compensation actually paid” to him or her: PEO 2024 Summary Compensation Table - Total Compensation (a) $3,600 - Grant Date Fair Value of Stock Awards and Option Awards Granted in Fiscal Year (b) $0 + Fair Value at Fiscal Year End of Outstanding and Unvested Stock Awards and Option Awards Granted in Fiscal Year (c) $0 + Change in Fair Value of Outstanding and Unvested Stock Awards and Option Awards Granted in Prior Fiscal Years (d) $98,798,127 + Fair Value at Vesting of Stock Awards and Option Awards Granted in Fiscal Year That Vested During Fiscal Year (e) $0 + Change in Fair Value as of Vesting Date of Stock Awards and Option Awards Granted in Prior Fiscal Years For Which Applicable Vesting Conditions Were Satisfied During Fiscal Year (f) $-1,405,426 - Fair Value as of Prior Fiscal Year End of Stock Awards and Option Awards Granted in Prior Fiscal Years That Failed to Meet Applicable Vesting Conditions During Fiscal Year (g) $0 = Compensation Actually Paid $97,396,301 Non-PEO NEO Average 2024 Summary Compensation Table - Total Compensation (a) $8,588,639 - Grant Date Fair Value of Stock Awards and Option Awards Granted in Fiscal Year (b) $7,870,183 + Fair Value at Fiscal Year End of Outstanding and Unvested Stock Awards and Option Awards Granted in Fiscal Year (c) $10,392,815 + Change in Fair Value of Outstanding and Unvested Stock Awards and Option Awards Granted in Prior Fiscal Years (d) $2,546,643 + Fair Value at Vesting of Stock Awards and Option Awards Granted in Fiscal Year That Vested During Fiscal Year (e) $662,118 + Change in Fair Value as of Vesting Date of Stock Awards and Option Awards Granted in Prior Fiscal Years For Which Applicable Vesting Conditions Were Satisfied During Fiscal Year (f) $-829,364 - Fair Value as of Prior Fiscal Year End of Stock Awards and Option Awards Granted in Prior Fiscal Years That Failed to Meet Applicable Vesting Conditions During Fiscal Year (g) $3,019,956 = Compensation Actually Paid $10,470,781 No dividends were paid during fiscal years 2022, 2023 and 2024 and GitLab does not maintain any pension plans, so there was no change in pension values during fiscal years 2022, 2023 or 2024. | | |

| Compensation Actually Paid vs. Total Shareholder Return | The following graph illustrates the relationship between compensation actually paid to our PEO and our non-PEO NEOs and our TSR for the period presented in the Pay-Versus-Performance table. | | |
| Compensation Actually Paid vs. Net Income | The following graph illustrates the relationship between compensation actually paid to our PEO and our non-PEO NEOs and our net income for the period presented in the Pay-Versus-Performance table. In fiscal 2023, as a high-growth company, GitLab emphasized revenue growth as a performance measure. Consequently, we did not use net income (loss) as a performance measure in our executive compensation program in fiscal 2023. Given this, we do not believe there is any meaningful relationship between our net income (loss) and compensation actually paid to our named executive officers during the periods presented. | | |
