As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K (the “PVP Rules”), we are providing information about the relationship between our company performance and executive compensation actually paid to our Principal Executive Officer (our “PEO”) and the other Named Executive Officers (the “Reported NEOs”), as calculated in accordance with Item 402(v) of Regulation S-K. For further information concerning our pay-for-performance philosophy and how we align executive compensation with our performance, see our Compensation Discussion and Analysis in this Proxy Statement and in our proxy statements filed for 2021, 2022, 2023 and 2024.

In the below pay versus performance table, we provide information about compensation of our Named Executive Officers for each of the last five fiscal years (the “Covered Years”). Additionally, we provide information about the results for certain financial performance measures during the Covered Years. Although the PVP Rules require us to disclose “compensation actually paid” (“CAP”), these amounts do not necessarily reflect compensation that our NEOs actually earned in the Covered Years. Instead, “compensation actually paid” reflects a calculation computed in accordance with the PVP Rules, including adjustments to the values of unvested and vested equity awards during the Covered Years based on either year-end or vesting date stock prices and various accounting valuation assumptions. “Compensation actually paid” generally fluctuates due to stock price performance.

1. Peter Beck served as the Company’s Principal Executive (our “PEO”) for the entirety of fiscal years 2021, 2022, 2023, 2024 and 2025. The Company’s other Reported NEOs for the indicated fiscal years were as follows:

•2025: A. Spice, F. Klein, and A. Kampani

•2024: A. Spice, F. Klein, and A. Kampani

•2023: A. Spice and A. Kampani

•2022: A. Spice, S. O’Donnell, and A. Kampani

•2021: A. Spice and S. O’Donnell

2. Amounts reported in these columns represent (i) the total compensation reported in the Summary Compensation Table for the indicated fiscal year in the case of our PEO and (ii) the average of the total compensation reported in the Summary Compensation Table for the Reported NEOs in the indicated year for such years.

3. Amounts reported in these columns represent the compensation actually paid to our PEO for the indicated fiscal year, as calculated under Item 402(v) of Regulation S-K based on his total compensation reported in the Summary Compensation Table for the indicated fiscal years and adjusted per the PVP Rules to determine compensation actually paid. Such adjustments for 2025 are shown in the table below.

Equity Award values are calculated in accordance with FASB ASC Topic 718, and the valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant.

4. Amounts reported in these columns represent the average compensation actually paid to the Reported NEOs in the indicated fiscal year, as calculated under Item 402(v) of Regulation S-K based on their total compensation reported in the Summary Compensation Table for the indicated fiscal years and adjusted per the PVP Rules to determine compensation actually paid. Such adjustments for 2025 are shown in the table below.

Please see footnote 1 for the Reported NEOs included in the average for each indicated fiscal year. Equity Award values are calculated in accordance with FASB ASC Topic 718, and the valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant.

5. Pursuant to Pursuant to Item 402(v) of Regulation S-K, the comparison assumes $100 was invested in our Common Stock on August 25, 2021, using the closing stock price of the end of the day we began training on the NASDAQ after our merger with Vector Acquisition Corporation (the “Business Combination”). Historic stock price performance is not necessarily indicative of future stock price performance.

6. The TSR Peer Group is the ARK Space Exploration & Innovation ETF. This calculation assumes that $100 was invested in this index on August 25, 2021 (aligned with the period used in footnote #5 above).

Note that per the PVP Rules, our Net Income for 2021, 2022, 2023, 2024 and 2025 is shown in the table above. Since none of our incentive programs for our Named Executive Officers are based on any specific financial criteria, we have omitted the “Company Selected Measure” column and the tabular list of financial performance metrics.
