What Masco Corporation told the SEC could break it.
Masco carries two extreme concentrations. On the demand side, a single customer dominates: The Home Depot bought about $2,859 million in 2025 — over half of Masco's roughly $5.2 billion in consolidated net sales, spanning all of its segments, with Behr granting Home Depot brand exclusivity — so the loss of that business would materially harm the company. On the cost side, its plumbing and coatings production depends on raw materials such as brass, copper, resins, titanium dioxide and zinc, whose prices and availability drive its margins. Those two pressures meet in trade policy: recently enacted tariffs, particularly on China, have significantly raised its costs (chiefly in Plumbing Products), which it is trying to offset through pricing, cost savings and sourcing changes even as higher prices risk dampening consumer demand.
3 self-disclosed vulnerabilities, pulled from its own filings — each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Commodity & input dependence
- brass, copper, resins, titanium dioxide and zinchigh
Masco's plumbing and coatings production depends on raw materials including brass, copper, resins, titanium dioxide and zinc; cost increases (from tariffs, inflation, FX or diminished availability) and procurement constraints have raised and could raise product prices and hurt results.
“Further, our production has been and may in the future be impacted if we or our suppliers are unable to procure our requirements for various raw materials, including, among others, brass, copper, resins, titanium dioxide and zinc.”
Customer concentration
- The Home Depot (~$2,859M, ~55% of net sales)high
Sales to one customer (The Home Depot, Masco's largest overall) were ~$2,859M in 2025 — over half of Masco's ~$5.2B consolidated net sales, spanning all segments — with Behr granting Home Depot brand exclusivity; loss of this business would materially harm Masco.
“Included in net sales were sales to one customer of $ 2,859 million, $ 3,010 million and $ 3,070 million in 2025, 2024 and 2023, respectively. Such net sales were included in each of our segments.”
SEC filing →As of 2026
Regulatory & policy
- China tariffs (Plumbing Products segment)high
Recently enacted tariffs — particularly those on China — have significantly raised Masco's costs, principally in its Plumbing Products segment; it seeks to mitigate via pricing, cost savings and sourcing changes, but higher prices could further dampen consumer demand.
“Additionally, we have been experiencing, and may continue to experience, significantly higher costs to us, principally in our Plumbing Products segment, due to the recently enacted tariffs, particularly those related to China. We seek to mitigate the impact of higher tariffs and other unfavorable impact to our costs over time with pricing, cost savings initiatives, sourcing changes, and other activities.”

Its customers
“Although other retailers, dealers, distributors, wholesalers and homebuilders represent other channels of distribution for our products and services, we might not be able to quickly replace, or replace at all, the loss of a substantial portion of our sales to The Home Depot or the loss of all of our sales to either Ferguson or Lowe's. Any such loss would have a material adverse impact on our business, results of operations and financial position.”
