Weyerhaeuser Reports Third Quarter Results

•

Generated net earnings of $80 million, or $0.11 per diluted share, and net earnings before special items of $40 million, or $0.06 per diluted share

•

Achieved Adjusted EBITDA of $217 million

•

Advanced capital-efficient transactions to enhance the company’s Timberlands portfolio

SEATTLE, October 30, 2025 – Weyerhaeuser Company (NYSE: WY) today reported third quarter net earnings of $80 million, or 11 cents per diluted share, on net sales of $1.7 billion. This compares with net earnings of $28 million, or 4 cents per diluted share, on net sales of $1.7 billion for the same period last year and net earnings of $87 million for second quarter 2025. Excluding an after-tax benefit of $40 million for special items, the company reported third quarter net earnings of $40 million, or $0.06 per diluted share. This compares with net earnings before special items of $35 million for third quarter 2024. There were no special items in second quarter 2025. Adjusted EBITDA for third quarter 2025 was $217 million, compared with $236 million for the same period last year and $336 million for second quarter 2025.

This afternoon, Weyerhaeuser announced updates on recent actions to optimize and improve its timberlands portfolio through a series of strategic and capital-efficient transactions. In the third quarter, the company completed two high-quality acquisitions totaling $459 million, including its previously announced transaction for timberlands in North Carolina and Virginia. Additionally, in the third quarter Weyerhaeuser advanced three divestiture packages of non-core timberlands – two of which were closed or under contract in early October, totaling $410 million of expected cash proceeds by year end. The company anticipates the third divestiture to close in early 2026, with total proceeds from all divestitures expected to exceed the cash outlay required for its recently completed acquisitions.

In September, Weyerhaeuser completed the sale of its lumber mill in Princeton, British Columbia for $85 million. The company received $61 million upon the sale of the lumber facility, with the remainder of the transaction proceeds to be received in conjunction with the transfer of associated timber licenses in the province. The transfer is expected to be completed over the coming months and is subject to customary closing conditions, including regulatory review.

“Our performance in the third quarter reflects solid execution against a very challenging market backdrop,” says Devin W. Stockfish, president and chief executive officer. “We remain well positioned to navigate the current environment given our deeply embedded OpX culture and competitive cost structure. In addition, we continue to capitalize on strategic opportunities to enhance our portfolio. Looking forward, we maintain a favorable outlook for the longer-term demand fundamentals that support growth for our businesses, and we remain focused on driving operational excellence, serving our customers and creating long-term value for our shareholders through our integrated portfolio and flexible capital allocation framework.”

(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)

Third quarter 2025 after-tax special items include a $21 million gain on the sale of our Princeton lumber mill and a $19 million insurance recovery. 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.

Q3 2025 Performance – Sales realizations for lumber and oriented strand board decreased 11 percent and 18 percent, respectively. For lumber, sales volumes were slightly lower and unit manufacturing costs were slightly higher, largely driven by a slight moderation in production levels in September. Log costs were moderately lower. For oriented strand board, sales volumes were comparable and unit manufacturing and fiber costs were moderately lower. For engineered wood products, sales realizations were slightly lower overall, but were comparable for solid section and I-joist products. Sales volumes were lower for most products, unit manufacturing costs were higher, and raw material costs were lower, primarily for oriented strand board webstock. Additionally, there was a one-time, small benefit from insurance proceeds associated with an early 2025 fire at the company's medium density fiberboard facility. Distribution results were lower than the second quarter, primarily due to lower sales volumes.

Third quarter pretax special items include a $29 million gain on the sale of the company’s Princeton lumber mill.

Q4 2025 Outlook – Weyerhaeuser anticipates fourth quarter earnings before special items and Adjusted EBITDA will be slightly lower than the third quarter, excluding the effect of changes in average sales realizations for lumber and oriented strand board. For lumber, the company expects lower sales volumes, comparable unit manufacturing costs, and moderately lower log costs. For oriented strand board, the company anticipates sales volumes and fiber costs to be comparable to the third quarter and unit manufacturing costs to be higher due to planned annual maintenance. For engineered wood products, the company expects sales volumes to be lower and sales realizations and raw material costs to be comparable to the third quarter. Distribution results are expected to be comparable to the third quarter.
