OF AN ADDITIONAL €75 MILLION OF 9.50% SENIOR SECURED NOTES DUE 2029

DALLAS, TEXAS – July 23, 2024 – Kronos Worldwide, Inc. (NYSE: KRO) (the “Company”) announced today that its wholly-owned subsidiary, Kronos International, Inc. (“KII”), has agreed to sell €75 million aggregate principal amount of additional 9.50% Senior Secured Notes due 2029 (the “Notes”) through an institutional private placement. The Notes will be issued as additional notes to the existing €276,174,000 aggregate principal amount of 9.50% Senior Secured Notes due 2029 that KII issued on February 12, 2024 (the “Existing Notes”). Other than with respect to the date of issuance and issue price, the Notes will have the same terms as the Existing Notes. The Notes will be maintained under the same ISIN and Common Code numbers as the Existing Notes, except that the Notes issued pursuant to Regulation S under the U.S. Securities Act of 1933, as amended (the “Securities Act”), will trade separately under different ISIN and Common Code numbers until 40 days after the issue date of the Notes, but thereafter, the Notes issued pursuant to Regulation S will be maintained under the same ISIN and Common Code numbers as the Existing Notes issued pursuant to Regulation  S.

The Notes will be fully and unconditionally guaranteed, jointly and severally, on a senior basis by the Company and each of its direct and indirect domestic, wholly-owned subsidiaries (other than the Issuer, the “Guarantors”), subject to certain exceptions and secured by first-priority security interests in certain assets of the Company and the Guarantors.

The Notes were oversubscribed and priced at a premium of 107.50%. The proceeds to the Company are expected to be approximately €80,625,000 (or approximately $87,500,000 at current exchange rates) before fees and expenses. The Company intends to use the proceeds of the offering, after payment of fees and expenses, to repay a portion of its global revolving credit facility with Wells Fargo, on which it drew in connection with its recently announced acquisition of the remaining equity interest that it did not already own of Louisiana Pigment Company. L.P., a chloride-process TiO₂ production facility located in Lake Charles, LA which the Company had previously operated as a 50% owned joint venture with Venator Materials. Subject to customary closing conditions, the closing of this offering is expected to occur on or about July 30, 2024.

This press release shall not constitute an offer to sell, or the solicitation of an offer to buy any of the Notes nor shall there be any sales of the Notes in any jurisdiction in which such offer, solicitation or sale would be unlawful without registration or qualification under the securities laws of any such jurisdiction. This notice is being issued pursuant to and in accordance with Rule 135(c) under the Securities Act.

The Notes and related guarantees subject to the private placement have not been and will not be registered under the Securities Act, or any state securities laws, and will be sold only to persons reasonably believed to be qualified institutional buyers in reliance on Rule 144A under the Securities Act and in offshore transactions to non-U.S. persons (within the meaning of Regulation S) outside the U.S. that are not “retail investors” residing in a member state of the EEA or the UK.
