Weyerhaeuser Company is a global forest products enterprise and real estate investment trust that manages one of the world's largest private timberland portfolios. The company owns or controls more than 10 million acres of timberlands across the United States and manages additional public timberlands in Canada under long-term licenses. Weyerhaeuser operates through three primary business segments: Timberlands, which focuses on sustainable forestry and timber harvesting; Wood Products, which manufactures lumber, structural panels, engineered wood products, and complementary building materials for residential, multi-family, industrial, and light commercial applications; and Real Estate and Natural Resources, which identifies and monetizes higher-value land uses and surface and subsurface assets. The company leverages its extensive landholdings to generate revenue from timber harvesting, wood product manufacturing, real estate sales, and emerging opportunities such as biocarbon products and carbon credits. Structured as a real estate investment trust, Weyerhaeuser benefits from tax advantages on timber harvest activities and maintains a commitment to managing its timberlands on a fully sustainable basis in compliance with internationally recognized forestry standards. The company serves diverse markets including construction, manufacturing, and energy sectors, distributing products through multiple channels to customers worldwide. Founded in 1900 and headquartered in Seattle, Washington, Weyerhaeuser combines traditional forest management with modern sustainable practices and innovative product development to maintain its position as a leader in the global forest products industry.
