Westlake Corporation (WLK) 10Y Growth Potential Analysis (2026)

Invetso Score: 3.8/10 — Weak · Last Updated: 2026-08-01

Overall Score

Growth Durability

Revenue growth is not supported by current profitability, with TTM net margin at -10.9% and operating margin at -10.9%.

Gross margin remains thin at 4.7%, limiting operating leverage unless pricing or mix improves.

Recent results do not yet show a durable earnings compounding profile.

Financial Strength

Current ratio is 2.45 and quick ratio is 1.70, indicating adequate short-term liquidity.

Debt remains manageable on a balance-sheet basis, with debt-to-equity at 0.66 and debt-to-capital at 0.40.

Cash generation is weak, with operating cash flow ratio at 0.23 and free cash flow still negative.

Profitability Trend

Return on equity is -13.9% and return on invested capital is -6.4%, showing value destruction at the current run rate.

Operating return on assets is -6.3%, consistent with persistent margin pressure.

Interest coverage is negative at -15.1x, reflecting current operating losses.

Reinvestment Runway

Capex remains heavy relative to operating cash flow at 2.06x, which constrains free cash flow conversion.

Working capital is positive at $3.37B, but the cash conversion cycle is still long at 92.7 days.

The company has room to reinvest, but current returns on capital are not yet attractive.

Valuation Support

EV/Sales of 1.24x and price/sales of 0.88x suggest the market is not pricing in strong growth.

Price/book of 1.14x is modest relative to the asset base.

Negative earnings and free cash flow keep traditional valuation support limited.
