• Increased full year Adjusted EBITDA by 31% to $2.1 billion with improvements in all segments

• Raised quarterly dividend

• Completed sale of 100,000 acres of Southern timberlands for $202.5 million in the fourth quarter

SEATTLE (February 2, 2018) - Weyerhaeuser Company (NYSE: WY) today reported fourth quarter net earnings of $271 million or 36 cents per diluted share, on net sales of $1.8 billion. This compares with net earnings from continuing operations of $62 million, or 8 cents per diluted share, on net sales of $1.6 billion for the same period last year.

Excluding a net after-tax benefit of $37 million from special items, the company reported net earnings of $234 million or 31 cents per diluted share. This compares with net earnings from continuing operations before special items of $106 million for the same period last year and $259 million for third quarter 2017.

For the full year 2017, Weyerhaeuser reported net earnings of $582 million, or 77 cents per diluted share, on net sales of $7.2 billion. This compares with net earnings from continuing operations of $415 million on net sales of $6.4 billion for the same period last year.

Full year 2017 includes net after-tax charges of $290 million from special items. Excluding these items, the company reported net earnings from continuing operations before special items of $872 million, or $1.15 per diluted share. This compares with net earnings from continuing operations before special items of $534 million for the full year 2016.

"2017 was a year of strong financial and operational performance for Weyerhaeuser. We increased Adjusted EBITDA by over 30 percent to $2.1 billion, generated over $1 billion of EBITDA from Wood Products, achieved all targets for operational excellence, merger cost synergies and overhead cost reduction, and raised our dividend,” said Doyle R. Simons, president and chief executive officer. “We also further simplified and optimized our portfolio by divesting our Uruguay operations, exiting the Twin Creeks joint venture and selling 100,000 acres of Southern timberland for collective proceeds of over $700 million. Going forward, we expect continued growth in the U.S. housing market and we remain relentlessly focused on improving performance through operational excellence, fully capitalizing on strengthening market conditions, and driving value for shareholders through disciplined capital allocation."

Fourth quarter includes a $99 million gain on the previously announced sale of 100,000 acres of Southern timberlands.

The company redeemed its ownership interest in the Twin Creeks Timber, LLC joint venture in October 2017. Fourth quarter results include no earnings contribution from operation of the joint venture.

1Q 2018 Outlook - Weyerhaeuser expects first quarter earnings before special items and Adjusted EBITDA to be comparable to the fourth quarter. In the West, the company anticipates improved average log sales realizations, partially offset by modestly lower fee harvest volumes.

Fourth quarter net pre-tax special charges of $41 million include $50 million for product remediation and a $9 million net benefit primarily from an adjustment to the periods covered and rates associated with the softwood lumber countervailing and antidumping duties.

1Q 2018 Outlook - Weyerhaeuser anticipates first quarter earnings before special items and Adjusted EBITDA from the Wood Products segment will be comparable to the fourth quarter.
