(2) Net earnings for 2017, 2018, 2019, 2020 and 2022 include net charges of $52 million, $122 million, $354 million, $285 million and $359 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 2015 2018 2016 2019 2017 2020 2018 2021 2022 2023 2024 Adjusted EBITDA(1) $2,080 $2,032 $1,276 $2,201 $4,094 $3,654 $1,694 $1,292 Depletion, depreciation & amortization (521) (486) (510) (472) (477) (480) (500) (502) Basis of real estate sold (81) (124) (116) (141) (71) (84) (93) (120) Unallocated pension service costs (4) — — — — — — — Special items included in operating income (343) (28) 1 122 97 (10) 85 15 Operating Income (GAAP) $1,131 $1,394 $651 $1,710 $3,643 $3,080 $1,186 $685 Non-operating pension and other post-employment benefit costs (62) (272) (516) (290) (19) (254) (45) (42) Interest income and other 40 60 30 5 5 25 76 53 Net Contribution to Earnings $1,109 $1,182 $165 $1,425 $3,629 $2,851 $1,217 $696 Interest expense, net (393) (375) (369) (351) (313) (270) (280) (269) Loss on debt extinguishment — — (9) (92) — (276) — — Income taxes (134) (59) 137 (185) (709) (425) (98) (31) Net Earnings (Loss) (GAAP)(2) $582 $748 $(76) $797 $2,607 $1,880 $839 $396 ADJUSTED EBITDA RECONCILIATION Total Company

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. ADJUSTED EBITDA RECONCILIATION Wood Products We have not provided a reconciliation of forecasted Adjusted EBITDA related to the new TimberStrand® facility in Monticello, Arkansas to the most comparable GAAP measure of net income because Adjusted EBITDA, excludes the impact of certain items described in the definition below, 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 expected impact of this investment to our historical results or the results or expected results of other companies that may have treated such matters differently. Nonetheless, management believes that providing this forward-looking non-GAAP information about this investment 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 EBITDA, as we define it, is operating income adjusted for depreciation, depletion, amortization, basis of real estate sold and special items. Adjusted EBITDA should not be considered in isolation from, and is not intended to represent an alternative to, our GAAP results. We have not provided a reconciliation of forecasted Adjusted EBITDA related to Natural Climate Solutions to the most comparable GAAP measure because Adjusted EBITDA excludes the impact of certain items described in the definition below and management cannot estimate the impact these items will have on Adjusted EBITDA without unreasonable effort. We believe that the probable significance of providing these forward-looking non-GAAP financial measures without a reconciliation to operating income is that investors and analysts will have certain information that we believe is useful and meaningful regarding our Natural Climate Solutions business, but they will not have that information on a GAAP basis. As a result, investors and analysts may be unable to accurately compare the expected impact to our historical results or the results or expected results of other companies that may have treated such matters differently. Management believes that, given the inherent uncertainty of forward-looking statements, investors and analysts will be able to understand and appropriately take into account the limitations in the information we have provided. Investors are cautioned that we cannot predict the occurrence, timing or amount of all non-GAAP items that we exclude from Adjusted EBITDA.
