Financial Profile 27/100

Based on FY2025 annual data. Scores normalized against common benchmarks. How we calculate these scores

Profitability
0

WESTLAKE CORPORATION has an operating margin of -14.1%, meaning the company retains $-14 of operating profit per $100 of revenue. This below-average margin results in a low score of 0/100, suggesting thin profitability after operating expenses. This is down from 7.2% the prior year.

Growth
20

WESTLAKE CORPORATION's revenue declined 8% year-over-year, from $12.1B to $11.2B. This contraction results in a growth score of 20/100.

Leverage
90

WESTLAKE CORPORATION carries a low D/E ratio of 0.58, meaning only $0.58 of long-term debt for every $1 of shareholders' equity. This conservative leverage earns a score of 90/100, indicating a strong balance sheet with room for future borrowing.

Liquidity
41

WESTLAKE CORPORATION's current ratio of 2.24 indicates adequate short-term liquidity, earning a score of 41/100. The company can meet its near-term obligations, though with limited headroom.

Cash Flow
13

While WESTLAKE CORPORATION generated $465.0M in operating cash flow, capex of $995.0M consumed most of it, leaving -$530.0M in free cash flow. This results in a low score of 13/100, reflecting heavy capital investment rather than weak cash generation.

Returns
0

WESTLAKE CORPORATION generates a -17.2% ROE, indicating limited profit relative to shareholders' investment. This results in a returns score of 0/100. This is down from 5.7% the prior year.

Piotroski F-Score Weak
2/9

WESTLAKE CORPORATION passes 2 of 9 financial strength tests. 2 of 4 profitability signals pass, no leverage/liquidity signals pass (rising debt, declining liquidity, or share dilution), neither operating efficiency signal passes.

Earnings Quality Mixed
-0.31x

For every $1 of reported earnings, WESTLAKE CORPORATION generates $-0.31 in operating cash flow ($465.0M OCF vs -$1.5B net income). This mixed ratio suggests some earnings may rely on non-cash accounting items.

Interest Coverage At Risk
-9.2x

WESTLAKE CORPORATION earns $-9.2 in operating income for every $1 of interest expense (-$1.6B vs $171.0M). This narrow margin raises concern about the company's ability to service its debt if operating income declines.
