Why Westlake’s latest earnings are back in focus

Westlake (WLK) is back on many investors’ radar after reporting second quarter 2026 results that showed a return to profitability, supported by higher pricing, lower feedstock costs, and company wide cost savings.

Westlake’s latest earnings have arrived after a choppy period, with the share price up 13.16% over the last week and 6.66% year to date. However, the 3 year total shareholder return has declined 37.40%, which points to improving short term momentum against a still weak longer term record.

Westlake now trades below both analyst targets and some intrinsic value estimates, even after the sharp rebound. Is the market being fairly cautious given its mixed multi year return record, or too slow to re rate the recovery story?

Most Popular Narrative: 18% Undervalued

Westlake’s most followed valuation narrative pegs fair value at $96, compared with the last close of $79.09, which frames the current rebound in a different light.

With a strong balance sheet, significant available cash, and focus on M&A in value-added and downstream segments, Westlake is positioned to continue portfolio diversification, capture opportunities in sustainable materials, and reduce business cyclicality. This may potentially drive revenue and earnings multiple expansion as the company aligns with circular economy and sustainability trends.

Want to see what sits behind that $96 figure for Westlake? The narrative leans heavily on future earnings, margin repair, and a richer profit multiple. The exact mix of growth, profitability, and discount rate assumptions might surprise you.

Result: Fair Value of $96 (UNDERVALUED)

However, Westlake’s story still carries real risk, including ongoing ethylene antitrust lawsuits in Europe and pressure from global chemical oversupply that can keep margins under strain.

Another View On Westlake’s Valuation
