Fiscal 2026 Tempel, a wholly owned subsidiary of Worthington Steel, owns a subsidiary in Canada (“Tempel Canada”). During the third quarter of fiscal 2026, the Company determined that certain internal-use software assets associated with a project at Tempel Canada were impaired. It was determined that it was no longer probable that the software being developed would be completed and placed in service. As the assessment for impairment for uncompleted software is performed at the module level, the assets associated with specific modules of the internal-use software assets were determined to have no value and were written down to zero, which resulted in a pre-tax impairment charge of $1.5 million for assets previously recorded in construction in progress.
