Regulation FD Disclosure (Form 8-K)

ITEM 7.01Regulation FD Disclosure.

​

On February 17, 2026, Trinseo Luxco Finance SPV, S.à r.l., a direct, wholly-owned subsidiary of the Company, elected to utilize a contractually-available 30-day grace period for the payment of interest under the terms of the indenture governing its 7.625% second lien secured notes due 2029 (the "2L Notes"). The Company has therefore elected to delay its next interest payment on the 2L Notes due on February 17, 2026, in the amount of approximately $10.0 million, notwithstanding that the Company has sufficient cash on hand to make such interest payment. Under the indenture governing the 2L Notes, the Company has until the end of the 30-day grace period to make the interest payment before such default triggers an event of default, and the Company retains its right to make all interest payments before the end of the applicable grace period. As previously disclosed, the Company is engaged in ongoing discussions with its financial stakeholders regarding its capital structure and the decision to utilize the grace period was made in connection with these discussions.
