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