PVC Pipe Prices Fall 9% as Utility Build-Out Grows
Minnesota construction suppliers face softer pipe demand while transmission spending continues to expand.
Updated on Nov. 4, 2026 in Construction
Otter Tail Corporation kept its 2026 adjusted diluted EPS midpoint at $5.88 and narrowed its guidance range to $5.73 to $6.03 in its third-quarter report. The company also raised its incremental capital spending opportunity to $850 million, which matters for Minnesota contractors and suppliers tied to its utility and transmission build-out.
Why it matters
Otter Tail is pointing to transmission projects and rate base growth as its main earnings engine, even as its building-products segment faces weaker demand. Elevated mortgage rates and rising developed-lot inventory are cooling residential construction, while input costs for resin have climbed, squeezing margins for PVC pipe makers.
Otter Tail's third-quarter revenue reached $320.51 million, down 1.6% year over year, while GAAP EPS was $1.41. Within its building products business, PVC pipe prices fell 9% and sales volume dropped 5%, even as resin and other input costs rose 10%.
The players
Otter Tail Corporation
A diversified Minnesota-based holding company with electric utility operations, a growing transmission portfolio, and a building products manufacturing segment that produces PVC pipe.
The details
The company's utility segment depends on a 10% five-year compound annual growth rate in rate base, which it expects will drive Otter Tail Power earnings at a similar pace. Its transmission program is facing siting and community engagement challenges, and the company says it is working directly with landowners, communities and local governments on those projects. Weaker PVC demand and higher resin costs show up as thinner margins in the building products line, which is more sensitive to housing activity.
Timeline
Third quarter 2026: Otter Tail reported GAAP EPS of $1.41 and revenue of $320.51 million.
Year-end 2026: The company expects to provide an update on transmission delays with its full-year results.
Market Landscape
Otter Tail's split performance mirrors a broader pattern in which utility and transmission spending holds up while housing-linked building materials soften under high mortgage rates. The company's own data shows developed-lot inventory rising, a signal that residential builders are slowing new starts.
Contractors and suppliers working on Minnesota transmission projects should watch for scheduling changes tied to siting and landowner engagement. Building-products distributors and PVC buyers should expect continued price pressure and lower volume while mortgage rates stay elevated.
The takeaway
Operators in construction supply should track resin input costs and developed-lot inventory as leading indicators of margin and demand. Review supplier contracts for resin pass-through terms before the next pricing cycle.
What happens next
Otter Tail expects to provide an update on transmission project delays with its year-end 2026 results, which will show whether siting and community challenges are pushing timelines.
