EX-99.1

Georgia and Alabama for $216 million and entered into an agreement to divest approximately 108,000 acres in Virginia for $193 million. The Virginia transaction is expected to close in first quarter 2026 and is subject to customary closing conditions.

In the fourth quarter, Weyerhaeuser completed the purchase of a group annuity contract that transferred approximately $455 million of the company’s U.S. pension liabilities to an insurance carrier. The contract purchase was funded from $440 million of U.S. pension plan assets. As a result of the transaction, fourth quarter special items include a non-cash after-tax settlement charge of $111 million. In conjunction with the transaction, the company made a $200 million voluntary cash contribution to the plan. This transaction is the latest in a series of actions taken to reduce the company’s pension plan obligations. Since beginning these efforts in 2018, Weyerhaeuser’s pension obligations have decreased from $6.8 billion to $1.9 billion as of December 31, 2025.

(1)

Net earnings before special items is a non-GAAP measure that management believes provides helpful context in understanding the company’s earnings performance. Additionally, 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 and special items. Net earnings before special items and Adjusted EBITDA should not be considered in isolation from, and are not intended to represent an alternative to, our GAAP results. Reconciliations of net earnings before special items and Adjusted EBITDA to GAAP earnings are included within this release.

(2)

Fourth quarter 2025 after-tax special items include a $117 million gain on the sale of Georgia and Alabama timberlands, a $149 million gain on the sale of Oregon timberlands, a $111 million pension settlement charge and a $14 million noncash environmental remediation charge. Special items for prior periods presented are included in the reconciliation tables within this release.

(3)

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. A reconciliation of Adjusted FAD to net cash from operations is included within this release.

Q4 2025 Performance – Earnings and Adjusted EBITDA increased from the third quarter due to the timing and mix of real estate sales. The average price per acre was significantly higher, while the number of acres sold and basis as a percentage of real estate sales were significantly lower.

Q1 2026 Outlook – Weyerhaeuser anticipates first quarter earnings before special items will be approximately $75 million higher than the fourth quarter and Adjusted EBITDA will be approximately $90 million higher than the fourth quarter due to the timing and mix of real estate sales and a large conservation easement transaction. The company expects full year 2026 Adjusted EBITDA for the segment to be approximately $425 million and basis as a percentage of real estate sales to be 25 to 35 percent for the full year.
