FOR IMMEDIATE RELEASE

**NL REPORTS THIRD QUARTER 2022 RESULTS**

​

DALLAS, TEXAS – November 2, 2022 - NL Industries, Inc. (NYSE: NL) today reported a net loss attributable to NL stockholders of $8.9 million, or $.18 per share, in the third quarter of 2022 compared to net income attributable to NL stockholders of $10.3 million, or $.21 per share, in the third quarter of 2021. NL results include an unrealized loss of $24.2 million in the third quarter of 2022 related to the change in value of marketable equity securities compared to a $1.2 million unrealized loss in the third quarter of 2021. For the first nine months of 2022, NL reported net income attributable to NL stockholders of $39.9 million, or $.82 per share, compared to net income attributable to NL stockholders of $36.3 million, or $.74 per share for the first nine months of 2021. NL results include an unrealized loss of $4.3 million in the first nine months of 2022 related to the change in value of marketable equity securities compared to a $9.7 million unrealized gain in the first nine months of 2021.  

Net sales were $42.9 million for the third quarter of 2022 compared to $34.5 million in the third quarter of 2021 and $126.6 million for the nine months ended September 30, 2022, compared to $106.7 million for the same prior year period. The increase in sales for both periods is due to higher Marine Components sales predominately to the towboat market and, to a lesser extent, higher Security Products sales across a variety of markets. Income from operations attributable to CompX was $6.0 million for the third quarter of 2022 compared to $5.1 million for the third quarter of 2021 and $20.0 million for the first nine months of 2022 compared to $16.7 million for the same prior year period. Income from operations increased for both comparative periods largely due to the strong performance of Marine Components, partially offset by increased production costs, particularly at Security Products, including increased raw material costs, higher shipping costs, and higher salary and employment related costs.  

​

The Company recognized equity in earnings of Kronos of $6.4 million in the third quarter of 2022 compared to $10.9 million in the third quarter of 2021 and $37.9 million in the first nine months of 2022 compared to $24.7 million in the same period of 2021. Kronos’ net sales of $459.6 million in the third quarter of 2022 were $40.2 million, or 8%, lower than in the third quarter of 2021. Kronos’ net sales of $1.6 billion in the first nine months of 2022 were $144.4 million, or 10%, higher than in the first nine months of 2021. Kronos’ net sales decreased in the third quarter of 2022 compared to the same period in 2021 primarily due to lower sales volumes in Kronos’ European, export and North American markets, partially offset by higher average TiO2 selling prices. Kronos’ net sales increased in the year-to-date period compared to the same period in 2021 primarily due to higher average TiO2 selling prices, partially offset by lower sales volumes. Kronos’ TiO2 sales volumes were 20% lower in the third quarter of 2022 as compared to the third quarter of 2021 and Kronos’ sales volumes in the first nine months of 2022 were 7% lower than in the first nine months of 2021. Kronos’ average TiO2 selling prices were 21% higher in the third quarter of 2022 as compared to the third quarter of 2021 and 24% higher in the first nine months of 2022 as compared to the first nine months of 2021. Kronos’s average TiO2 selling prices at the end of the third quarter of 2022 were 15% higher than the end of 2021. Fluctuations in currency exchange rates (primarily the euro) also affected net sales comparisons, decreasing net sales by approximately $31 million in the third quarter of 2022 and approximately $83 million in the first nine months of 2022, as compared to the same periods in 2021. The table at the end of this press release shows how each of these items impacted Kronos’ net sales.

​

Kronos’ income from operations in the third quarter of 2022 was $30.8 million as compared to $57.3 million in the third quarter of 2021. For the year-to-date period, Kronos’ income from operations was $179.3 million as compared to $135.1

million in the first nine months of 2021. Kronos’ income from operations decreased in the third quarter of 2022 as compared to the third quarter of 2021 primarily due to the net effect of lower sales volumes and higher production costs, including raw material and energy costs and higher average TiO2 selling prices. Kronos’ income from operations increased in the first nine months of 2022 as compared to the first nine months of 2021 primarily due to the net effect of higher average TiO2 selling prices, lower sales volumes, higher production costs, including raw material and energy costs. Kronos’ TiO2 production volumes were 5% lower in the third quarter of 2022 compared to the third quarter of 2021 and 1% lower in the first nine months of 2022 compared to the same period of 2021.  The lower production volumes in the third quarter of 2022 were primarily due to maintenance activities and alignment of Kronos’ production and inventory levels to anticipated near-term customer demand. Kronos operated its production facilities at 96% of practical capacity utilization in the first nine months of 2022 (100%, 95% and 93% in the first, second and third quarters of 2022, respectively) compared to 99% in the first nine months of 2021 (97 %, 100% and 100% in the first, second and third quarters of 2021, respectively). Fluctuations in currency exchange rates (primarily the euro) increased Kronos’ income from operations approximately $13 million in the third quarter of 2022 as compared to the third quarter of 2021 and increased Kronos’ income from operations approximately $21 million in the first nine months of 2022 as compared to the first nine months of 2021.

​

Kronos’ other operating income, net in the first nine months of 2022 includes an insurance settlement gain of $2.7 million (NL’s equity interest was $.5 million, or $.01 per share, net of income tax expense) related to a 2020 business interruption insurance claim recognized in the third quarter of 2022.

​

Corporate expenses decreased $.1 million in the third quarter of 2022 compared to the third quarter of 2021 primarily due to lower environmental remediation and related costs somewhat offset by higher litigation fees and related costs. Corporate expenses increased $1.1 million in the first nine months of 2022 compared to the same period of 2021 primarily due to higher litigation fees and related costs. Interest and dividend income increased in the third quarter and in the first nine months of 2022 compared to the same periods of 2021 primarily due to higher average interest rates on invested balances. Marketable equity securities represent the change in unrealized gains (losses) on our portfolio of marketable equity securities during the periods.
