Celanese Corporation reported that its wholly owned subsidiary, Celanese US Holdings LLC, has moved to redeem all of its outstanding 4.777% Senior Notes due July 19, 2026. The action was disclosed under Item 8.01, “Other Events,” in a current report dated June 10, 2026. On that date, Celanese US Holdings LLC issued a notice of redemption for the notes under the indenture governing the securities. The redemption is expected to take place on June 25, 2026. The redemption price will be equal to 100% of the principal amount of the notes being redeemed, plus accrued and unpaid interest up to, but not including or through as specified in the governing documents, the June 25, 2026 redemption date. The filing states that all outstanding notes in the series are subject to the redemption. Celanese also noted that the Form 8-K itself does not constitute the formal notice of redemption for the notes; rather, the notice was issued separately by Celanese US Holdings LLC pursuant to the indenture. The report was signed on behalf of Celanese Corporation by Ashley B. Duffie, Senior Vice President, General Counsel and Corporate Secretary, on June 10, 2026. The transaction reflects a near-maturity debt management step by Celanese, retiring the 4.777% senior notes roughly three weeks before their scheduled July 19, 2026 maturity date. No share issuance, insider transaction, equity award, vesting event, or change in beneficial ownership was reported in this filing.
