WEYERHAEUSER CO

We use Adjusted EBITDA as a key performance measure to evaluate the performance of the consolidated company and our business segments. This measure should not be considered in isolation from, and is not intended to represent an alternative to, our results reported in accordance with U.S. generally accepted accounting principles (U.S. GAAP). However, we believe Adjusted EBITDA provides meaningful supplemental information for our investors about our operating performance, better facilitates period to period comparisons and is widely used by analysts, lenders, rating agencies and other interested parties. Our definition of Adjusted EBITDA may be different from similarly titled measures reported by other companies. Adjusted EBITDA, as we define it, is operating income adjusted for depreciation, depletion, amortization, basis of real estate sold and special items.

Adjusted EBITDA by Segment

WEYERHAEUSER COMPANY >2025 ANNUAL REPORT AND FORM 10-K 57

We reconcile Adjusted EBITDA to net earnings for the consolidated company and to operating income (loss) for the business segments, as those are the most directly comparable U.S. GAAP measures for each.

The table below reconciles Adjusted EBITDA by segment to net earnings for the year ended December 31, 2025:

(1)

Non-operating pension and other post-employment benefit costs includes a pretax special item consisting of a $145 million noncash settlement charge related to the transfer of pension plan assets and liabilities to an insurance company through the purchase of a

group annuity contract.

(2)

Operating income (loss) for Timberlands includes pretax special items consisting of a $117 million gain on the sale of Georgia and Alabama timberlands and a $149 million gain on the sale of Oregon timberlands.

(3)

Operating income (loss) for Wood Products includes a pretax special item consisting of a $29 million gain on the sale of our Princeton lumber mill.

(4)

Operating income (loss) for Unallocated Items includes pretax special items consisting of an $18 million noncash environmental remediation charge and a $26 million insurance recovery.

The table below reconciles Adjusted EBITDA by segment to net earnings for the year ended December 31, 2024:

Operating income (loss) for Wood Products includes pretax special items consisting of a $25 million product remediation recovery and a $10 million noncash impairment charge related to the indefinite curtailment of our New Bern lumber mill.

Net Earnings and Net Earnings per Diluted Share Before Special Items (Income Tax Affected)

We reconcile net earnings before special items to net earnings and net earnings per diluted share before special items to net earnings per diluted share, as those are the most directly comparable U.S. GAAP measures. We believe the measures provide meaningful supplemental information for investors about our operating performance, better facilitate period to period comparisons, and are widely used by analysts, lenders, rating agencies and other interested parties.

Adjusted FAD

We use Adjusted Funds Available for Distribution (Adjusted FAD) to evaluate the company’s liquidity and measure cash generated during the period (net of capital expenditures and significant nonrecurring 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, results reported in accordance with U.S. GAAP. However, we believe the measure provides meaningful supplemental information for our investors about our liquidity. Adjusted FAD, as we define it, is net cash from operations adjusted for capital expenditures and significant non-recurring items. Our definition of Adjusted FAD may be different from similarly titled measures reported by other companies, including those in our industry. We reconcile Adjusted FAD to net cash from operations, as that is the most directly comparable U.S. GAAP measure.
