What NL Industries, Inc. told the SEC could break it.
NL Industries' disclosures reflect a holding company whose fortunes ride on its two operating affiliates, each with its own concentration. Kronos drew about 90% of its 2025 sales from titanium dioxide, so it is highly exposed to TiO2 pricing and demand cycles, and its feedstock — rutile, slag and ilmenite — comes from a limited number of suppliers concentrated in Australia, South Africa, Norway, Canada and India. CompX, meanwhile, leans on the U.S. Postal Service at 26% of its net sales, with its top ten customers about 52%. Both businesses are exposed to tariffs: Kronos makes much of its North American TiO2 in Canada, so U.S. tariffs on Canadian imports would raise its costs, while CompX already incurred surcharges on China-sourced electronic components.

In its own words
What could break it.
Commodity & input dependence
- Kronos ~90% dependent on the TiO2 industryhigh
NL's Kronos affiliate derived ~90% of its sales from titanium dioxide (TiO2) in 2025, so Kronos' earnings are highly exposed to TiO2 industry pricing and demand cycles.
“Kronos' sales and profitability are largely dependent on the TiO 2 industry. In 2025, approximately 90% of Kronos' sales were attributabl”

Customer concentration
- CompX: USPS = 26% of net sales; top-10 customers = 52%high
NL's CompX subsidiary has customer concentration — the United States Postal Service was 26% of CompX's consolidated net sales in 2025 and the ten largest Component Products customers were ~52% of sales — so loss of USPS or a few large OEMs would materially hit CompX.
“CompX sells to a diverse customer base with only one customer representing 10% or more of its consolidated net sales in 2025 (United States Postal Service representing 26%). CompX's largest ten customers accounted for approximately 52% of its sales in 2025.”

Regulatory & policy
- tariffs — Kronos Canada-made TiO2 imported to US; CompX China electronic-component surchargesmedium
Kronos manufactures a significant portion of its North American TiO2 in Canada, so US tariffs on Canadian imports would raise its costs/prices, and CompX already incurred tariff surcharges on China-sourced electronic components — exposing both businesses to trade policy.
“As Kronos currently manufactures a significant portion of its North American TiO 2 in Canada, if sustained for an extended period of time, a tariff on Kronos' imports into the U.S. from Canada, would make its products manufactured in Canada and sold into the U.S. more expensive.”

Supplier concentration
- titanium-containing feedstock available only from a limited number of geographically concentrated suppliersmedium
Kronos' TiO2 feedstock (rutile/slag/ilmenite) comes from a limited number of suppliers concentrated in Australia, South Africa, Norway, Canada and India; political/economic instability or regulation in those countries could impair raw-material availability.
“Titanium-containing feedstocks suitable for use in Kronos' TiO 2 facilities are available from a limited number of suppliers around the world. Political and economic instability or increased regulations in the countries from which Kronos purchases or mines its raw material supplies could adversely affect raw material availability.”
