Westlake now sits near recent lows despite the legal relief and mixed earnings expectations. Does that setup still offer an appealing balance between downside risk and potential upside, as the valuation section spells out the numbers?

Most Popular Narrative: 3% Overvalued

Westlake's most followed narrative points to a fair value of about $70 per share, slightly below the last close of $71.72. This frames the latest legal win against a cautious earnings recovery path.

Global overcapacity in polyethylene and the chlorovinyl chain, combined with weak industrial activity in 2025, created sharp pricing pressure in PEM. If capacity additions and Chinese export behavior continue to weigh on PVC and caustic even after VAT rebate changes, PEM margins could stay compressed around low single digit levels, constraining earnings.

Want to see what keeps this fair value close to today's price? The narrative leans on muted revenue traction, modest margin repair and a punchy future earnings multiple. The full story joins those ingredients into one valuation view.

Result: Fair Value of $70 (OVERVALUED)

However, Westlake could still surprise if the 3 pillar plan delivers the targeted $600 million earnings uplift and the Housing and Infrastructure Products segment sustains its 20% EBITDA margin.
