Pay vs Performance Disclosure, Table | PAY VS. PERFORMANCE 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, we are providing the following information about the relationship between executive compensation actually paid (as calculated in accordance with such rule) (CAP) and certain financial performance metrics of Tidewater. Amounts reflected in the tables below for prior years have been updated to reflect the updated 2022 and 2023 values reported in the Summary Compensation Table, as discussed in notes 3 and 5 thereto, and to correct for inadvertent errors in calculating the equity award adjustments of previously awarded stock options and PRSU’s. As discussed in the CD&A above, our C&HC Committee has implemented an executive compensation program designed to link a substantial portion of our NEOs’ realized compensation to the achievement of Tidewater’s financial, operational, and strategic objectives, and to align our executive pay with changes in the value of our shareholders’ investments. For further information concerning Tidewater’s pay for performance philosophy and how Tidewater aligns executive compensation with performance, see “Compensation Discussion and Analysis—Pay-for-Performance Driven” beginning on page 41.
