KRONOS WORLDWIDE REPORTS FIRST QUARTER 2017 RESULTS

DALLAS, TEXAS…May 8, 2017… Kronos Worldwide, Inc. (NYSE:KRO) today reported net income of $36.8 million, or $.32 per share, in the first quarter of 2017 compared to a net loss of $3.8 million, or $.03 per share, in the first quarter of 2016.  We reported net income in the first quarter of 2017 as compared to a net loss in the 2016 period primarily due to higher income from operations in 2017 resulting from the favorable effects of higher average selling prices, higher sales and production volumes and lower raw materials and other production costs, as discussed below.

Net sales of $369.8 million in the first quarter of 2017 were $51.4 million, or 16%, higher than in the first quarter of 2016.  Net sales increased in the first quarter 2017 as compared to the same period in 2016 due to higher average TiO₂ selling prices and higher sales volumes.  The Company's average TiO₂ selling prices were 17% higher in the first quarter of 2017 as compared to the first quarter of 2016, and our average selling prices at the end of the first quarter of 2017 were 4% higher than at the end of 2016, with higher prices in all major markets.  TiO₂ sales volumes in the first quarter of 2017 were 3% higher as compared to the first quarter of 2016 due to higher sales in the North American and export markets, partially offset by lower sales in the European market.  Kronos' sales volumes in the first quarter of 2017 set a new overall record for a first quarter period.  Fluctuations in currency exchange rates (primarily the euro) also affected net sales comparisons, decreasing net sales by approximately $7 million in the first quarter 2017 as compared to the first quarter of 2016.  The table at the end of this press release shows how each of these items impacted the overall increase in sales.

The Company's TiO₂ segment profit (see description of non-GAAP information below) in the first quarter of 2017 was $56.5 million as compared to $3.8 million in the first quarter of 2016.  Segment profit increased in the first quarter of 2017 as compared to the first quarter of 2016 primarily due to higher average TiO₂ selling prices, higher sales and production volumes and lower raw materials and other production costs.  Kronos' TiO₂ production volumes were 10% higher in the first quarter of 2017 as compared to the first quarter of 2016.  We operated our production facilities at an overall average capacity utilization rate of 100% in the first quarter of 2017 compared to approximately 97% in the first quarter of 2016.  Fluctuations in currency exchange rates also affected segment profit comparisons, which decreased segment profit by approximately $8 million.

Other operating income, net in 2016 includes an insurance settlement gain of $2.0 million ($1.5 million, or $.01 per share, net of income tax expense) related to a 2014 business interruption claim.

The Company's income tax expense in 2017 includes a $5.0 million ($.04 per share) non-cash deferred income tax benefit as a result of a net decrease in our deferred income tax asset valuation allowance related to our German and Belgian operations.

The statements in this release relating to matters that are not historical facts are forward-looking statements that represent management's beliefs and assumptions based on currently available information.  Although the Company believes that the expectations reflected in such forward-looking statements are reasonable, it cannot give any assurances that these expectations will prove to be correct.  Such statements by their nature involve substantial risks and uncertainties that could significantly impact expected results, and actual future results could differ materially from those described in such forward-looking statements. While it is not possible to identify all factors, the Company continues to face many risks and uncertainties.  The factors that could cause actual future results to differ materially include, but are not limited to, the following:

Should one or more of these risks materialize (or the consequences of such a development worsen), or should the underlying assumptions prove incorrect, actual results could differ materially from those forecasted or expected.  The Company disclaims any intention or obligation to update or revise any forward-looking statement whether as a result of changes in information, future events or otherwise.

In an effort to provide investors with additional information regarding the Company's results of operations as determined by accounting principles generally accepted in the United States of America (GAAP), the Company has disclosed certain non-GAAP information, which the Company believes provides useful information to investors:

·

The Company discloses segment profit, which is used by the Company's management to assess the performance of the Company's TiO2 operations.  The Company believes disclosure of segment profit provides useful information to investors because it allows investors to analyze the performance of the Company's TiO2 operations in the same way that the Company's management assesses performance.  The Company defines segment profit as income before income taxes, interest expense and certain general corporate items.  Corporate items excluded from the determination of segment profit include corporate expense and interest income not attributable to the Company's TiO2 operations.

Kronos Worldwide, Inc. is a major international producer of titanium dioxide products.
