What Gorman-Rupp Co. told the SEC could break it.

Substantially all materials used to fabricate Gorman-Rupp's pumps — castings, structural steel, bar stock, motors, engines, seals and plastic/elastomeric components — are purchased from outside suppliers, exposing margins to raw-material price and availability swings the company may not be able to pass on to customers.

“Substantially all of the materials, supplies, components and accessories used by the Company in the fabrication of its products, including all castings (for which most patterns are made and owned by the Company), structural steel, bar stock, motors, solenoids, engines, seals, and plastic and elastomeric components are purchased by the Company from other suppliers and manufacturers.”

U.S. tariffs on imported materials and products — and trade conflicts with China, Mexico and Canada — may increase the cost of imported materials used by Gorman-Rupp's suppliers, who may pass those costs along, pressuring the company's margins.

“The U.S. administration has implemented numerous tariffs on imported materials and products and, in response, various countries have imposed new, or increased existing, tariffs on imports. These tariffs, to the extent that they continue to be imposed, and any new or increased tariffs, may increase the cost of imported materials used by our supplie”

Gorman-Rupp purchases motor components for its large submersible pumps and motors and engines for its pump systems from a limited number of suppliers (though it states it is not dependent on a single source), and does not buy materials under long-term contracts.

“The Company purchases motor components for its large submersible pumps, and motors and engines for its pump systems, from a limited number of suppliers.”
