Westlake (WLK) is back on investors’ radar after reporting second quarter 2026 results that showed a move from a net loss a year ago to net income of US$260 million.

Despite the return to profitability and a regular dividend that has been paid and increased over 22 years, Westlake’s recent 90 day share price return declined 11.79% and its 1 year total shareholder return declined 3.60%. This signals fading momentum after a stronger year to date share price return of 5.48%.

For Westlake, the share price has lagged even as earnings moved back into the black and the dividend track record continued. Does that set up a reasonable entry now, or is it better to remain patient and wait for a cheaper price?

Most Popular Narrative: 16.6% Undervalued

Westlake closed at $78.21, while the most followed narrative pegs fair value closer to $93.73. That gap hinges on how investors see long term infrastructure demand and an earnings turnaround playing out.

The multi-year increase in municipal infrastructure spending in the U.S., fueled by the Infrastructure Act and ongoing underspend in water infrastructure, is structurally supporting long-term demand for Westlake's HIP (Housing and Infrastructure Products) segment, particularly for PVC pipes and fittings. This is creating a reliable revenue and volume growth driver that is not affected by near-term housing volatility.

Want to see what powers that valuation gap for Westlake? The narrative leans on a profit recovery path, steadier HIP revenue, and a future earnings multiple that needs careful scrutiny.

Result: Fair Value of $93.73 (UNDERVALUED)

However, there are still real pressure points for Westlake, including ongoing ethylene antitrust litigation and persistent global oversupply in core chemical chains that keeps pricing under strain.
