Sierra Pacific Industries

What Sierra Pacific Industries does

Sierra Pacific Industries (SPI) is a privately held, family-owned vertically integrated timber and forest products company headquartered in Redding, California, founded over 70 years ago and controlled by the Emmerson family. The Emmerson family's landholdings exceed 2.2 million acres, making SPI America's largest private landowner as of 2022. The company operates across California, Oregon, and Washington, harvesting and processing six primary softwood species (Ponderosa Pine, Sugar Pine, Douglas Fir, Incense Cedar, White Fir, and Western Hemlock) through a network of sawmills, with downstream operations in millwork, mouldings, fencing, fiber products, cogeneration, and conifer seedling propagation. Sierra Pacific Windows operates as a separately branded division manufacturing windows and doors, with plants including a newly opened facility in Phenix City, Alabama capable of supporting up to 600 jobs.

The business model combines commodity lumber sales (specialty, structural, dimension, and fencing grades), value-added millwork and mouldings, branded windows and doors through acquired brands (Hurd, Semco), fiber byproducts, and clean electricity generated from wood waste via cogeneration. Distribution is executed through dedicated direct sales forces segmented by product line, a dedicated export department serving international lumber markets, and dealer networks across North America. The company holds SFI (SFI-00027) and FSC (FSC C084658) certifications, markets a Sierra Premium lumber sub-brand, and operates a conifer seedling nursery launched with CAL FIRE to produce 25 million seedlings for reforestation.

Revenue is not publicly disclosed. Growth has been driven by a combination of organic capacity additions (Lane County, Oregon mills) and acquisitions of complementary family-owned or branded businesses (Simpson Lumber assets in 2015, Hurd Windows & Doors completed 2015, Semco Window and Doors in 2020, and Seneca in 2021). The company has also institutionalized government-facing activities, including a $75 million US Forest Service wildfire prevention and hazardous fuel reduction partnership announced in 2025 and longstanding cooperative arrangements with the Bureau of Land Management and conservation organizations such as Trust for Public Land.
