HUBB · CIK 48898
What Hubbell Incorporated told the SEC could break it.
Hubbell's disclosures cluster on the cost of inputs and the channel it sells through. Its products draw on a broad set of commodity raw materials — steel, aluminum, brass, copper, bronze, zinc, nickel, plastics and petrochemicals — plus electronic components, so while it isn't reliant on any single supplier, disruptions to cost or availability can hurt results. Trade policy is the sharpest version of that: it sources materials, components and finished goods from Mexico, China and elsewhere, and tariff expense contributed roughly 5 points of margin contraction in 2025, with further tariff increases on Canada, Mexico, China and Europe a continuing threat. On the demand side, its top ten customers — distributors, utilities and contractors — account for about 42% of net sales, a meaningful channel concentration.

In its own words
What could break it.
Commodity & input dependence
- metals and petrochemical raw materialsmedium
Hubbell's products use steel, aluminum, brass, copper, bronze, zinc, nickel, plastics, elastomers and petrochemicals plus electronic components; while not dependent on any one supplier, raw-material cost/availability disruptions can hurt results.
“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.”
Customer concentration
- top ten customers (~42% of net sales)medium
Hubbell isn't dependent on a single customer, but its top ten customers account for ~42% of net sales across its distributor/utility/contractor base — a meaningful channel concentration.
“We are not dependent on a single customer, however, our top ten customers account for approximately 42% of our Net sales.”
SEC filing →As of 2026
Regulatory & policy
- import tariffs (Canada, Mexico, China, Europe)medium
Hubbell sources materials/components/finished goods from Mexico, China and other countries; tariff expense contributed to ~5 points of 2025 margin contraction, and further tariff increases on Canada/Mexico/China/Europe goods could materially hurt results.
“We cannot predict what changes to trade policy will be made, or the economic impact that changes to trade policy will have, including significant increases in tariffs on goods imported into the United States, particularly tariffs on products manufactured in Canada, Mexico, China, and in Europe and the length of time such tariffs may remain in place”
