Westlake’s (WLK) Second Quarter Turned Two Straight Losses Into Profit

On August 4, Westlake Corporation (NYSE:WLK) reported a turnaround in its second-quarter results, erasing two consecutive losses and reporting a net income of $260 million, or $2.01 per share. This marked a stark contrast to the $169 million loss in the previous quarter and the $142 million loss a year earlier. EBITDA nearly tripled from the previous quarter.

The improvement centered around the Performance and Essential Materials (PEM) segment, which shifted from an operating loss of $318 million in the second quarter of 2025 to $185 million in profit. The increase in PEM's EBITDA margins from 3% to 21% was driven by a 14% rise in average sales prices year-over-year in the segment. This pricing recovery outweighed a 3% decline in the Housing and Infrastructure Products segment and a 7% increase in companywide sales volume, excluding shutdowns and acquisitions.

Westlake also reduced its debt by $500 million and returned $99 million to shareholders via dividends and share repurchases. However, the Housing and Infrastructure Products segment saw its EBITDA margin drop to 22% from 24% a year earlier, despite a 6% increase in volume. The turnaround in PEM's performance was largely driven by pricing rather than volume growth.

The first quarter of 2026 highlighted the volatility of the sector, as the company posted a $169 million net loss three months prior, burdened by $85 million in identified items, including litigation settlements and facility shutdowns. Hedge fund ownership rose to 39 funds from 34 in the prior quarter, indicating growing institutional skepticism.

With a forward price-to-earnings ratio of 15.02, Westlake's stock price suggests the market is uncertain about whether the recent earnings power will be sustained beyond the current quarter. While the turnaround demonstrates the effectiveness of Westlake's three-pillar profitability plan, the recent improvement may not be sustainable if margins in Housing and Infrastructure Products continue to soften.
