Stimson Lumber Company

What Stimson Lumber Company does

Stimson Lumber Company is a family-owned, integrated wood products enterprise headquartered in Portland, Oregon, that controls the full vertical from forest to finished product. The company owns and manages more than 600,000 acres of timberland across Oregon, Idaho, Montana, and Washington, and operates five active sawmills and a wet-process hardboard plant (Clatskanie, Forest Grove, Priest River, St. Maries, and Tillamook), with a sixth mill at Plummer, Idaho permanently closed in September 2024. Its product portfolio comprises six categories — kiln-dried and green studs, Douglas Fir dimension lumber, specialty grades (crossarms, transmission arms, lamstock, crane/timber mats, mining timbers), rough and surfaced timbers up to 40 feet, Western Red and Japanese Cedar, and hardboard panels — all SFI-certified since 2000 and graded to WWPA/WCLIB standards.

Underlying technology centers on conventional lumber milling, kiln drying, anti-stain treatment, and wet-process hardboard production, augmented by drone-based forest management (five Part 107-certified foresters using UAS for tree counting, harvest mapping, inspections, and stockpile volumetrics) and a structured 45-year, six-phase forestry lifecycle model (planning, preparing, planting, protecting, evaluating, renewing). Stimson is also developing Improved Forest Management (IFM) forest carbon offset projects on its timberlands, including a 100,000-acre Montana Forestlands Carbon Project seeking a partner in voluntary carbon markets.

The business model is predominantly direct, quote-based B2B sales through regional teams in Portland covering studs, dimension lumber, specialty grades, timbers, cedar, and hardboard, with dedicated product-line reps and a national accounts function. Distribution uses a multi-modal mix of rail (Burlington Northern, Santa Fe, Union Pacific connections via Portland & Western, Pend Oreille Valley, and St. Maries River railroads) and truck (flatbed, maxi, OTR van). Secondary revenue streams include log and timber purchases from private woodland owners, land sales through the Land.com marketplace, and emerging forest carbon credit transactions. The customer base is horizontally diversified across retail building material suppliers, residential and commercial construction, industrial heavy-equipment and mining, utility power transmission, glulam manufacturers, and corporate carbon offset buyers.

Direct peers

• Hampton Lumber: Family-owned sawmill operator with multiple mills in Oregon, Washington, and British Columbia producing Douglas Fir and Western Red Cedar studs, dimension lumber, and specialty products. Closely comparable as a private PNW softwood sawmill competitor with overlapping customer base.
• Boise Cascade: Publicly traded manufacturer of engineered wood products (I-joists, LVL, plywood/OSB) and wholesale building products distribution with sawmill operations. Comparable as a major PNW-oriented wood products manufacturer competing in similar construction end markets.
• Roseburg Forest Products: Privately held integrated forest products manufacturer in Oregon and the U.S. South producing lumber, plywood, particleboard, and engineered wood. Highly comparable as a private PNW competitor; Stimson previously sold its Duratemp plywood siding product line to Roseburg in 2008.
• PotlatchDeltic: A timberland REIT and wood products manufacturer operating across the U.S. South and Pacific Northwest with sawmills producing lumber and specialty products. Closely comparable as a timberland-owning sawmill operator; Stimson even purchased 33,000 acres from PotlatchDeltic in 2011-2014.
• Sierra Pacific Industries: One of the largest privately held, vertically integrated lumber and millwork manufacturers in the U.S., owning roughly 2 million acres of California/Oregon/Washington timberland. Highly comparable as a family-owned, fully integrated private competitor with similar PNW footprint and species mix.
• Green Diamond Resource Company: Family-owned timberland and forest products company operating in Oregon, Washington, and California with substantial timberland ownership and mill operations.

Emerging players

• Cascade Forest Products: PNW-based manufacturer of cedar and Doug Fir products serving specialty and appearance-grade markets. Comparable as a smaller private PNW lumber manufacturer focused on cedar and premium-grade products, partially overlapping with Stimson's specialty grades and cedar product lines.

Broad incumbents

• Weyerhaeuser: One of the world's largest private owners of softwood timberland and an integrated wood products manufacturer with significant PNW and U.S. South operations. Highly comparable as a vertically integrated timberland/sawmill competitor; meaningfully larger in scale and public, serving as the dominant industry benchmark.

Regional players

• Idaho Forest Products: Family-owned sawmill operator headquartered in Idaho producing dimension lumber, studs, and specialty lumber from Inland Empire timber. Comparable as a regional Inland Empire sawmill competitor sourcing from similar species and serving overlapping stud/dimension markets.

Others

• Plum Creek (now part of Weyerhaeuser): Historical direct peer — Plum Creek was the largest private timberland owner in the U.S. before merging into Weyerhaeuser in 2016. Stimson purchased 81,000 acres from Plum Creek in the early 2000s, illustrating close historical comparability in the Inland Empire timberland market.
