What Insteel Industries, Inc. told the SEC could break it.
Insteel's earnings live and die by steel. Its products are made from hot-rolled steel wire rod, and that input dominates its economics — a 10% rise in wire rod prices, absent matching selling-price increases, would have cut fiscal 2025 pre-tax earnings by $37.5 million. Trade policy compounds that exposure: the Section 232 tariff on steel was doubled from 25% to 50%, and as a derivative steel product its PC strand is subject to a 50% tariff on its steel portion, with broader tariffs potentially lifting other input costs. On the demand side it is concentrated, with about 70% of net sales going to concrete-products manufacturers and roughly 85% tied to the cyclical nonresidential construction market.

In its own words
What could break it.
Commodity & input dependence
- hot-rolled steel wire rod raw-material price exposurehigh
Insteel's products are made from steel wire rod; a 10% rise in wire rod prices (absent matching selling-price increases) would have cut FY2025 pre-tax earnings by $37.5 million, making earnings highly sensitive to steel input costs.
“Based on our 2025 shipments and average wire rod cost reflected in cost of sales, a 10% increase in the price of wire rod would have resulted in a $37.5 million decrease in our annual pre-tax earnings (assuming there was not a corresponding change in our selling prices).”
Regulatory & policy
- Section 232 steel/aluminum tariffs raised to 50%high
The Section 232 tariff on steel and aluminum was raised from 25% to 50%; as a derivative steel product, Insteel's PC strand is subject to a 50% tariff on its steel portion, and broader tariffs could raise costs of other inputs amid uncertain U.S. trade policy.
“The Section 232 tariff on steel and aluminum was recently increased to 50% from 25%. As a derivative steel product, PC strand is also subject to a 50% tariff rate on the steel portion of the product.”
Customer concentration
- ~70% of sales to concrete-products manufacturers; ~85% nonresidential construction end-marketmedium
About 70% of Insteel's FY2025 net sales went to manufacturers of concrete products, with ~85% tied to nonresidential construction — concentrating demand in a single customer class and cyclical end-market.
“In fiscal 2025, we estimate that approximately 70% of our net sales were to manufacturers of concrete products and 30% were to distributors, rebar fabricators and contractors.”
