Business Overview: NL Industries, Inc. (NYSE: NL)

---

Executive Summary

NL Industries, Inc. is a New Jersey holding company, organized in 1891, that holds controlling and minority stakes in two very different industrial businesses: an 87%-owned lock and locking-mechanism manufacturer (CompX International) and a 31% noncontrolling stake in a global titanium dioxide (TiO2) pigment producer (Kronos Worldwide). NL itself has no direct employees — it operates entirely through its subsidiaries, its affiliate, and an intercorporate services agreement with its ultimate parent, Contran Corporation.

NL matters as a pure holding-company play inside the Valhi/Contran corporate family, giving investors indirect exposure to global TiO2 pigment economics (through Kronos) alongside a smaller, more stable security-hardware manufacturing business (CompX), all wrapped inside a tightly controlled ownership structure.

1. Core Business Model & How They Work

[ NL Industries (holding company, no employees) ]
        │
        ├── 87% ownership ➡️ [ CompX International — locks/marine components ] ➡️ Consolidated segment results
        │
        └── 31% noncontrolling stake ➡️ [ Kronos Worldwide — TiO2 pigments ] ➡️ Equity-method income

Key Operational Drivers

1. Pure holding-company structure: NL generates no operating revenue itself; its results are entirely a function of CompX's consolidated performance and its equity interest in Kronos.
2. TiO2 pigment economics: Kronos' profitability depends on global TiO2 capacity utilization, pigment pricing, and feedstock (titanium ore) costs — cyclical, commodity-chemical dynamics largely outside NL's direct control.
3. Concentrated customer exposure at CompX: the U.S. Postal Service alone accounted for 26% of CompX's 2025 net sales, with the top ten customers at ~52% — a meaningful single-customer concentration.
4. Contran intercorporate services: NL relies on an intercorporate services agreement with Contran for administrative functions rather than maintaining its own staff.

Component Products (CompX International)

Manufactures locks and locking mechanisms for postal, furniture, and cabinetry markets, plus marine components, from three U.S. plants with 549 employees.

Chemicals (Kronos Worldwide)

A global TiO2 pigment producer with roughly 3,000 customers across ~100 countries; core TiO2 pigments were about 90% of Kronos' 2025 net sales, with plants in Europe, Canada, and Louisiana and 2,263 employees at year-end 2025.

4. Competitive Landscape

• CompX's lock/hardware competitors: various security-hardware manufacturers competing for furniture, cabinetry, and postal-equipment contracts; the USPS relationship in particular reflects a long-standing, specialized supplier position.
• Kronos' global TiO2 competitors: the four largest global TiO2 producers hold about 42% of worldwide capacity; Kronos itself holds roughly a 7% share of global TiO2 sales volume, making it a mid-sized player in a concentrated, capital-intensive global industry.

5. Strategic Strengths & Risks

Strengths

• Diversified exposure through two distinct businesses: CompX's niche, relationship-driven hardware manufacturing is largely uncorrelated with Kronos' global commodity-chemical cycle.
• Sticky institutional relationship at CompX: a long-standing USPS supply relationship (26% of 2025 net sales) reflects durable, hard-to-displace specification-level integration.
• Full consolidation of Louisiana Pigment Company: Kronos' 2024 acquisition of the remaining 50% simplifies its production structure and captures full economics of that capacity.

Risks

• Holding-company structure limits direct control: NL's Kronos exposure is a noncontrolling 31% equity stake, meaning NL cannot unilaterally direct Kronos' capital allocation or strategy.
• TiO2 cyclicality: Kronos' ~77% capacity utilization in 2025 points to a pigment market currently running below full capacity, a cyclical commodity-chemical risk that flows through to NL's equity-method income.
• Customer concentration at CompX: USPS at 26% of CompX's net sales is a significant single-customer dependency; loss or reduction of that relationship would meaningfully affect the segment.
• Controlled-company governance: Valhi (83% owner of NL) is itself ~91%-controlled by Contran, with the Simmons family trust ultimately in control — minority shareholders have limited influence over strategic direction.

7. Summary Conclusion

NL Industries is best understood not as an operating company but as a holding vehicle giving investors indirect, leveraged exposure to two very different businesses: a niche, relationship-driven lock manufacturer with a decades-long USPS relationship, and a noncontrolling stake in a mid-sized global TiO2 pigment producer navigating a currently under-utilized commodity-chemical cycle. The structural ceiling on NL's moat is its own ownership position — a 31% noncontrolling Kronos stake means NL captures Kronos' economics without controlling its strategy, while the broader Valhi/Contran controlled-company structure means minority NL shareholders are, in practice, passengers on decisions made at the Contran level.
