Key Financial Trends

Westlake (NYSE: WLK) showed a sharp improvement in early 2025 and 2026 after a difficult stretch in late 2025, but the latest quarter still reflects a business under pressure.

Q1 2026 ended with a strong cash position of $2.27 billion in cash and equivalents, plus $205 million in short-term investments.
The company’s balance sheet remains sizable, with $19.7 billion in total assets and $9.1 billion in total equity and noncontrolling interests.
Operating cash flow turned positive again in Q4 2025 at $225 million after being negative in Q1 2025 and Q1 2026, showing the business can still generate cash in better quarters.
Q1 2026 depreciation and other non-cash charges helped offset the quarterly loss, a sign that reported earnings are being supported by a capital-intensive operating model.
Gross margin improved materially versus the weakest periods in 2025, with Q1 2026 gross profit of $112 million compared with a much deeper loss in Q4 2025 and Q3 2025 operating results.
Revenue in Q1 2026 was $2.65 billion, down slightly from Q4 2025 and Q3 2025, suggesting demand is stable but not clearly accelerating.
Capital spending remains steady, with Q1 2026 purchases of property, plant and equipment at $209 million, indicating ongoing maintenance and growth investment requirements.
The company continues to pay dividends, with Q1 2026 cash dividends to common shareholders of $0.53 per share, which may appeal to income investors but also consumes cash.
Q1 2026 ended with a net loss of $169 million attributable to common shareholders, or -$1.31 per share.
Operating income was also negative at -$172 million, meaning the core business did not cover operating costs in the quarter.
The gross margin remains thin: revenue of $2.65 billion versus cost of revenue of $2.54 billion left only $112 million of gross profit.
Leverage is meaningful, with $5.07 billion in long-term debt and $496 million in short-term debt on the Q1 2026 balance sheet.
Balance sheet quality weakened year over year, as goodwill rose sharply from $1.31 billion in Q3 2025 to $1.35 billion in Q1 2026, while liabilities also increased.
Cash declined by $452 million in Q1 2026, driven by negative operating cash flow, investing outflows, and dividend payments.
The prior quarters show pronounced volatility, including a large Q3 2025 impairment charge of $727 million and Q4 2025 restructuring charge of $501 million, highlighting a challenging operating backdrop.

Bottom line: Westlake’s recent data points suggest a cyclical manufacturer that can produce solid cash flow in stronger periods, but profitability has been volatile and the latest quarter was still loss-making. Investors will likely want to see sustained improvement in operating margins and cash generation before calling the turnaround durable.
