On August 21, 2026, Insteel Industries Inc. issued a Press Release announcing that its wholly-owned subsidiary, Insteel Wire Products Company (together referred to as “Insteel” or the “Company”), will be closing its facility in Upper Sandusky, Ohio, and moving the manufacturing to the Company’s remaining welded wire reinforcement production facilities.

The consolidation of the Company’s welded wire manufacturing operations is expected to result in the elimination of up to 65 positions at the Upper Sandusky facility. It is anticipated that operations at the facility will cease by the end of October 2026. Insteel expects to incur a restructuring charge of approximately $4.6 million related to the facility’s closure, which includes $2.5 million for equipment relocation costs, $0.4 million for employee separation costs, $1.0 million for asset impairment and $0.7 million for other closure-related costs. Insteel expects that the restructuring charges, other than asset impairment, will consist of cash expenditures, which are anticipated to begin in the first quarter of fiscal 2027 and continue through the remainder of the fiscal year.
