On August 4, Westlake Corporation (NYSE:WLK) reported second-quarter results that erased two consecutive quarterly losses in a single swing. Net income landed at $260 million, or $2.01 per share, compared with a $169 million loss just three months earlier and a $142 million loss a year ago. EBITDA nearly tripled from the second quarter of 2025. The numbers mark a sharp reversal for a company whose chemicals business had been bleeding red ink.
Materials Business Roars Back To Life
The turnaround centers on Performance and Essential Materials, the segment that makes chlorovinyls and other basic chemicals. PEM swung from a $318 million operating loss in the second quarter of 2025 to $185 million in income this quarter, while EBITDA excluding identified items jumped from a 3% margin to 21%. The driver was pricing: average sales prices across PEM rose 14% year over year, more than offsetting a 3% price decline in the Housing and Infrastructure Products segment. Combined with a 7% increase in companywide sales volume, excluding the effects of plant shutdowns and an acquisition, the pricing recovery pushed companywide EBITDA to $679 million from $210 million a year earlier.
Westlake is also working the balance sheet alongside the market recovery. The company reduced debt by $500 million during the quarter and returned $99 million to shareholders through dividends and share repurchases. Management says its three-pillar profitability improvement plan remains on track to deliver a $600 million operating income benefit, a target that, if it holds, would layer structural cost savings on top of whatever the market gives back in pricing.
Housing Segment Loses Its Edge
Not every part of the story improved together. Housing and Infrastructure Products, the segment tied to home construction and building products, saw its EBITDA margin slip to 22% from 24% a year earlier, even as volume rose 6% excluding the ACI acquisition. Average sales prices in that segment fell 3% year over year, a sign that pricing power in housing products has softened even as the company sells more of it.
The improvement in the core chemicals business also leans heavily on price rather than volume. PEM’s turnaround came from a 14% jump in average sales price, a figure that can move in either direction with commodity cycles. The first quarter of 2026 was a reminder of how quickly conditions shift: Westlake posted a $169 million net loss just three months before this result, weighed down by $85 million in identified items, including a $67 million charge to settle litigation over PVC pipe and fittings and $18 million tied to facility shutdowns. A year earlier, in the second quarter of 2025, the company absorbed another $130 million in shutdown-related charges. Restructuring and legal charges showed up in two of the last three reported quarters.
Funds Keep Buying Despite Skepticism
Hedge fund ownership rose to 39 funds from 34 in the prior quarter, a modest increase in institutional conviction. Short interest sits at 17.44% of the float, a level that points to heavy organized skepticism. Westlake trades at a forward price-to-earnings ratio of 15.02, as of September 16, a multiple that assumes the second quarter’s earnings power holds rather than reverting to the losses of the prior two quarters. That gap, between funds adding shares and short sellers holding a crowded bet against the stock, captures the market’s uncertainty about which quarter was the outlier.
Which Quarter Was The Outlier
Westlake’s second quarter answered one question and raised another. The swing from consecutive losses to $260 million in net income shows the three-pillar plan and a firmer pricing environment can move the numbers fast. But the same speed that turned a loss into a profit could just as easily turn it back, especially with Housing and Infrastructure Products margins already softening. For the recovery to hold, pricing gains in Performance and Essential Materials need to persist beyond a single quarter.
