NL Industries reported a 2025 fourth-quarter net loss of $31.0 million, or $0.63 per share, reversing a $16.5 million profit in Q4 2024. Results included a $4.5 million unrealized loss on marketable equity securities and a $19.7 million after-tax charge related to the termination of its U.S. pension plan.

For the full year of 2025, NL posted a net loss of $37.8 million, or $0.77 per share, compared to a $67.2 million net income in 2024. The annual results reflected a $13.6 million unrealized securities loss and absence of the prior year’s $31.4 million environmental remediation settlement income.

CompX generated Q4 net sales of $37.7 million, down from $38.4 million, but lifted segment profit to $5.6 million on stronger Marine Components sales and improved margins. Kronos net sales fell 1% to $418.3 million in Q4 and posted a $63.1 million operating loss, driven by an 8% decline in average TiO2 selling prices and shifts in product mix despite currency gains.
