Pay Versus Performance

The MDCC designed our executive compensation program to link a majority of our NEOs’ realized compensation to achievement of Sylvamo’s financial, commercial and strategic goals, and to align executives’ interest with those of shareowners. The table below shows the total compensation for our NEOs for the past five years, the “compensation actually paid” to our CEO and, on an average basis, our other NEOs, our TSR, the TSR of the S&P Small Cap Materials Index, our net income and our financial performance measure for compensatory purposes, Free Cash Flow.

(1) On October 1, 2021, the Company spun off from International Paper and became a publicly traded company, as such we are reporting fiscal 2025, 2024, 2023, and 2022 and the period October 1, 2021 through December 31, 2021.

(2) The amounts shown in this column represent the total compensation per the Summary Compensation Table (see page 46) for our CEO, Mr. Ribiéras, for the fiscal years 2025, 2024, 2023, 2022 and the period October 1, 2021 through December 31, 2021.

(3) The amounts shown for 2022, 2023, and 2024 were revised in the Summary Compensation Table (see page 46) as part of “All Other Compensation” for the “Personal Use of Charter Aircraft” to reflect travel conducted during our 2022, 2023, and 2024 fiscal years, respectively. In prior proxy statements, for 2022, 2023, and 2024 we disclosed amounts in the “All Other Compensation” table based on the 12-month period used for IRS reporting. The above disclosure represents an increase over the prior disclosed amount of $51,384 for 2022 and a decrease of $14,154 for 2023 and $34,016 for 2024.

(4) SEC rules require certain adjustments be made to the Summary Compensation Table totals to determine “compensation actually paid” as reported above. The amounts shown do not necessarily reflect the actual amounts of compensation paid to our CEO or non-CEO NEOs (“Other NEOs) during the applicable year as they include (i) the year-end value of equity awards granted during the reported year that have not yet vested, (ii) the change in the value of equity awards that were unvested at the end of the prior year, measured through the date the awards vested or were forfeited, or through the end of the fiscal year and (iii) certain pension related costs. The NEOs included for 2025 are Messrs. Devlin, Sims, Barron, Davoli and Ms. Kalman, for 2024 are Messrs. Sims, Barron, Davoli and Wilczynski, for 2023 are Messrs. Sims, Barron, Davoli and Gibson, for 2022 are Messrs. Sims, Gibson, Barron and Wilczynski, and for 2021 Messrs. Sims, Gibson, Cleves and Wilczynski.
