“Raw materials used in the manufacture of Hubbell products primarily include steel, aluminum, brass, copper, bronze, zinc, nickel, plastics, elastomers and petrochemicals. Hubbell also purchases certain electrical and electronic components, including solenoids, printed circuit boards, integrated circuit chips and cord sets, from a number of suppliers. Hubbell is not materially dependent upon any one supplier for raw materials used in the manufacture of its products and equipment however the cost and supply of these materials may be affected by disruptions in availability of raw materials, components or sourced finished goods.”

“Following completion of the PFS for the Santa Cruz Copper Project, we are advancing detailed engineering, operational readiness, and permitting for a copper mining operation incorporating leading technologies to improve efficiencies and costs.”

“Our primary commodity cost exposures relate to steel, copper and leather.”

“Information about our exposure to metal commodity price market risks and a sensitivity analysis related to our metal commodity hedges is presented below (in millions): Notional amount (pounds of aluminum and copper) 87.6 Carrying amount and fair value of net asset $ 23.6 Change in fair value from 10% change in forward prices $ 13.2”

“The Company uses various metals in the manufacturing of its products, including copper, zinc, tin, gold, silver, and ruthenium.”

“particularly tariffs on steel, aluminum and copper and products manufactured in China, Canada and Mexico, and adverse responses by foreign governments to U.S. trade policies, among other possible changes.”

“Nickel is a prime material in stainless steel which the Company utilizes to manufacture CSST, and copper is a key component of the Company's brass fittings and our MediTrac ® CMT.”

“The costs of raw materials used by our Mineral Nutrition business are particularly subject to fluctuations in global commodities markets and cost changes in the underlying commodities markets typically lead directly to a corresponding change in our revenues.”

“Ralliant's manufacturing operations employ a wide variety of raw materials, including electronic components, steel, plastics and other petroleum-based products, aluminum, and copper.”

“Base materials for our products consist primarily of steel, copper and aluminum. Additionally, significant components of our product costs consist of bearings, plastic, electronic assemblies, electronic components, permanent magnets and ferrous and non-ferrous castings.”

“We are subject to fluctuations in the cost of raw materials used to manufacture our materials and products. In particular, we are exposed to market fluctuations in commodity pricing as we utilize certain materials, such as copper and ceramic, which are key materials in certain of our products.”

“Our market risk exposure is primarily a result of fluctuations in steel, aluminum and copper prices and customer concentrations.”

“Our critical raw materials include polymers, graphite, copper and stainless steel. For most of these materials, we purchase from multiple suppliers to avoid any potential disruption of our manufacturing operations. For a small number of raw material items that require specific quality specifications, we have single source supply arrangements.”

“Supply for PCB materials can vary over time depending on supply/demand dynamics for key raw materials such as copper clad laminates.”
