What Worthington Steel, Inc. told the SEC could break it.
Worthington Steel's two sharpest exposures are the auto industry and steel-tariff policy. About 52% of its net sales go to automotive customers, with the Detroit Three automakers alone roughly 33% and its two largest automotive customers individually 14% and 12%, so an auto-production downturn or the loss of a major customer would hit it hard. As a steel processor holding inventory, it's also directly exposed to Section 232 tariffs — reinstated at 25% on steel and aluminum in March 2025 and doubled to 50% in June — which, along with retaliatory foreign tariffs and excessive low-priced imports, drive the steel-price volatility that shapes its business (fiscal 2025 selling prices fell about 6% and volumes about 5%).

In its own words
What could break it.
Customer concentration
- automotive end-market / Detroit Three automakershigh
Approximately 52% of Worthington Steel's net sales are to automotive-related customers, with the Detroit Three automakers (GM/Ford/Stellantis) representing ~33% of net sales in fiscal 2025; its two largest automotive customers individually accounted for 14% and 12% of net sales (both >10%, not named in the filing). A significant loss from these customers or an auto-production downturn would materially impact sales.
“Approximately 52% of our net sales are to automotive-related customers. Although we do sell to the domestic operations of foreign automakers and their suppliers, a significant portion of our automotive sales are to the Detroit Three automakers and their suppliers.”
SEC filing →As of 2025
Regulatory & policy
- Section 232 steel and aluminum tariffshigh
Section 232 measures reinstated a blanket 25% tariff on all steel imports (and raised aluminum to 25%) effective March 12, 2025, revoking country-specific exemptions and product exclusions; a June 3, 2025 proclamation doubled the steel and aluminum duties to 50% effective June 4, 2025. These tariffs, plus retaliatory foreign tariffs, drive steel-price volatility and shifts in customer purchasing that directly affect Worthington Steel's processing business.
“On February 10, 2025, new Section 232 measures reinstated a blanket 25% tariff on all steel imports and raised aluminum tariffs from 10% to 25%, effective March 12, 2025, revoking prior country-specific exemptions and halting product exclusions. On June 3, 2025, President Trump elevated these tariffs under Section 232 once again by signing a proclamation doubling the steel and aluminum duties to 50%, effective June 4, 2025.”
Commodity & input dependence
- steel price volatilitymedium
As a steel processor holding steel inventory, Worthington Steel is exposed to U.S. steel-price volatility; excessive low-priced steel imports exert downward pressure on prices, and in fiscal 2025 direct selling prices fell ~6% with volumes down ~5%, pressuring net sales (which declined $337.3M to $3,093.3M).
“Excessive imports of steel into the U.S. have exerted, and may continue to exert, downward pressure on U.S. steel prices.”
