AI Brief

Q2 FY26 earnings call · Aug 4, 2026
Q2 FY26

TL;DR. Westlake reported Q2 2026 EBITDA of $679M, more than double Q2 2025's $340M, driven by PEM's 21% sequential price increase, a $150M YoY contribution from its three-pillar profit plan, and HIP's 6% volume growth; however, HIP's 2026 revenue and EBITDA margin guidance was trimmed to the lower end of prior ranges amid soft residential construction and inflation.

Bullish
  • + Q2 EBITDA doubled YoY to $679M from $340M.
  • + Three-pillar profitability plan delivered ~$150M YoY EBITDA benefit in Q2 toward the $600M 2026 target.
  • + Reduced debt by $500M and returned $99M to shareholders while ending Q2 with $1.9B cash/investments and an investment-grade balance sheet.
  • + Closed acquisition of PVC/VCM Wilhelmshaven, Germany site with deep-water port access to integrate low-cost North American feedstocks.
Bearish
  • − Guided HIP 2026 revenue and EBITDA margin to the lower end of prior ranges due to weaker residential construction and cost inflation.
  • − HIP EBITDA margin contracted to 22% from 24% YoY on lower price and transportation/raw material inflation.
  • − PEM first-half plant reliability still trailed targets due to residual unplanned outages in Q2.
