Total Company ADJUSTED EBITDA RECONCILIATION 1. Adjusted EBITDA is a non-GAAP measure that management uses to evaluate the performance of the company. Adjusted EBITDA, as we define it, is operating income adjusted for depreciation, depletion, amortization, basis of real estate sold, unallocated pension service costs and special items. Adjusted EBITDA excludes results from joint ventures. Adjusted EBITDA should not be considered in isolation from, and is not intended to represent an alternative to, our GAAP results. 2. Net earnings (loss) for 2017, 2018, 2019, 2020, 2022 and 2025 include net charges of $52 million, $122 million, $354 million, $285 million, $359 million and $111 million, respectively, of after-tax non-operating special items which are reported in non-operating pension and other post-employment benefit costs, interest income and other, interest expense, net, and income taxes. $ Millions 2017 2018 2019 2020 2021 2022 2023 2024 2025 Adjusted EBITDA1 $2,080 $2,032 $1,276 $2,201 $4,094 $3,654 $1,694 $1,292 $1,021 Depletion, depreciation & amortization (521) (486) (510) (472) (477) (480) (500) (502) (509) Basis of real estate sold (81) (124) (116) (141) (71) (84) (93) (120) (84) Unallocated pension service costs (4) — — — — — — — — Special items included in operating income (343) (28) 1 122 97 (10) 85 15 303 Operating Income (GAAP) $1,131 $1,394 $651 $1,710 $3,643 $3,080 $1,186 $685 $731 Non-operating pension & other post-employment benefit costs (62) (272) (516) (290) (19) (254) (45) (42) (220) Interest income & other 40 60 30 5 5 25 76 53 22 Net Contribution to Earnings $1,109 $1,182 $165 $1,425 $3,629 $2,851 $1,217 $696 $533 Interest expense, net (393) (375) (369) (351) (313) (270) (280) (269) (273) Loss on debt extinguishment — — (9) (92) — (276) — — — Income taxes (134) (59) 137 (185) (709) (425) (98) (31) 64 Net Earnings (Loss) (GAAP)2 $582 $748 $(76) $797 $2,607 $1,880 $839 $396 $324 We have not provided a reconciliation of forecasted Adjusted EBITDA to the most comparable GAAP measure of net earnings because Adjusted EBITDA excludes the impact of certain items described in the definition above, and management cannot estimate these items or the impact they will have on Adjusted EBITDA on a forward-looking basis without unreasonable effort. As a result, investors may be unable to accurately compare the results or expected results of other companies that may define and calculate Adjusted EBITDA differently. Nonetheless, management believes that providing this forward-looking non-GAAP information is useful to investors, and given the uncertain nature of forward-looking statements, we believe investors are able to take into account the inherent limitations of this forward-looking non-GAAP information. We cannot reasonably predict the occurrence, timing or amount of any of the items that we exclude from our Adjusted EBITDA estimate. Accordingly, the actual effect of these items, when determined, could potentially be significant to the calculation of Adjusted EBITDA and actual results may differ materially from our estimate.

ADJUSTED FUNDS AVAILABLE FOR DISTRIBUTION (FAD) RECONCILIATION 1. Funds available for distribution (FAD) is a non-GAAP measure that management uses to evaluate the company's liquidity. FAD, as we define it, is net cash from operations adjusted for capital expenditures. FAD measures cash generated during the period (net of capital expenditures) that is available for dividends, repurchases of common shares, debt reduction, acquisitions, and other discretionary and nondiscretionary capital allocation activities. FAD should not be considered in isolation from, and is not intended to represent an alternative to, our GAAP results. 2. Adjusted funds available for distribution (Adjusted FAD) is a non-GAAP measure that management uses to evaluate the company's liquidity. Adjusted FAD, as we define it, is net cash from operations adjusted for capital expenditures and significant non-recurring items. Adjusted FAD measures cash generated during the period (net of capital expenditures and significant non-recurring items) that is available for dividends, repurchases of common shares, debt reduction, acquisitions, and other discretionary and nondiscretionary capital allocation activities. Adjusted FAD should not be considered in isolation from, and is not intended to represent an alternative to, our GAAP results. $ Millions 2017 2018 2019 2020 2021 2022 2023 2024 2025 Net cash from operations $1,201 $1,112 $966 $1,529 $3,159 $2,832 $1,433 $1,008 $562 Capital expenditures (excluding discontinued operations) (419) (427) (384) (281) (441) (468) (447) (416) (474) Funds Available for Distribution1 $782 $685 $582 $1,248 $2,718 $2,364 $986 $592 $88 Cash for product remediation payments (from product remediation insurance recoveries) 192 96 (68) (8) — (37) — (25) — Cash tax payments attributable to Cellulose Fibers divestiture 75 — — — — — — — — Monticello engineered wood products facility capital expenditures — — — — — — — — 109 Cash contribution to (cash tax refund associated with contribution to) our U.S. qualified pension plan — 300 — — (95) — — — 200 Adjusted Funds Available for Distribution2 $1,049 $1,081 $514 $1,240 $2,623 $2,327 $986 $567 $397

OTHER NON-GAAP FINANCIAL MEASURES This presentation references forward-looking estimates of free cash flow yield, Adjusted EBITDA multiple and return on investment (ROI), each of which is a non-GAAP financial measure that management uses to evaluate the performance of the company and certain investments. Free cash flow yield, as we define it, is calculated by dividing free cash flow — defined as Adjusted EBITDA generated less capital expenditures to support operations — by the purchase price of the investment. Adjusted EBITDA multiple is calculated by dividing the purchase price by the company's forecasted Adjusted EBITDA. ROI is calculated by dividing forecasted cash flow by invested capital. These measures should not be considered in isolation from, and are not intended to represent alternatives to, our GAAP results. We have not provided a reconciliation of these forward-looking non-GAAP financial measures to the most comparable GAAP measure of net cash from operations (in the case of free cash flow), net earnings (in the case of Adjusted EBITDA multiple) and return on assets (in the case of ROI), because they each exclude the impact of certain items that are inherently difficult to forecast, such as changes in working capital, capital expenditures, and asset sales. Management cannot estimate these items or their impact on free cash flow yield, Adjusted EBITDA multiple or ROI on a forward-looking basis without unreasonable effort. As a result, investors may be unable to accurately compare our historical results to those of other companies that may define or calculate free cash flow yield, Adjusted EBITDA multiple, or ROI differently. Nonetheless, management believes that providing this forward-looking non-GAAP information is useful to investors. Given the uncertain nature of forward-looking statements, we believe investors are able to take into account the inherent limitations of this forward-looking non-GAAP information. Actual results may differ materially from our estimates due to the potential significance of the excluded items.
