Debt refinancing in motion: tender 2026 notes and issue new senior notes to reshape maturities.

Westlake launched a cash tender for any and all of its 3.600% Senior Notes due 2026 and announced an underwritten offering of new senior unsecured notes. This is classic liability management: retire near‑term debt and replace it with longer‑dated paper via the shelf registration on Form S‑3.

Outcomes hinge on pricing, participation, and terms in the Offer to Purchase. Interest expense could rise or fall depending on the new coupon; liquidity depends on the offering’s size and settlement alignment with tender outflows. Both actions are subject to market conditions and the tender’s stated terms and conditions.

Key items to watch: tender uptake rate for the 2026 notes, final coupon and tenor of the new notes, and settlement timing relative to November 2025 announcement. If execution is smooth, the maturity profile extends past 2026; investors should monitor the final results press release tied to the tender expiration and the pricing of the new issue when announced.
