Understanding ROE

Return on Equity (ROE) measures how efficiently a company generates profits from shareholders' equity. For CSTM, the current ROE is 46.22%.

Why ROE Matters

Warren Buffett has called ROE one of his favorite metrics because it shows how well management uses shareholders' capital to generate returns. A company that consistently earns 15%+ ROE is typically a well-run business that creates value for shareholders.

High Leverage Warning

CSTM's debt-to-equity ratio of 3.49x is elevated. High ROE combined with high debt can be a red flag — the company may be using financial leverage to boost returns, which increases risk. Compare to ROIC for a more complete picture.

ROE Benchmarks

Excellent: >20%

Exceptional returns on equity. Often indicates strong competitive advantages. Common in capital-light businesses.

Good: 15-20%

Above-average ROE. Buffett often looks for companies in this range or higher.

Average: 10-15%

Typical for most companies. Returns are reasonable but not exceptional.

Below Average: <10%

May indicate poor capital allocation or challenging business conditions.

The DuPont Analysis

ROE can be decomposed into three components using DuPont analysis:

ROE = Net Margin × Asset Turnover × Equity Multiplier

This breakdown reveals whether high ROE comes from high profitability (good), efficient asset use (good), or high leverage (potentially risky).

ROE vs ROIC: Which is Better?

ROIC: 9.02% →

ROIC measures returns on ALL capital. It's more comprehensive and less affected by leverage. Often considered the better quality metric.

ROE: 46.22%

ROE only measures returns on equity. Can be inflated by high debt. If ROE >> ROIC, the company uses significant leverage.

Owner Earnings: $243.0M →

Shows actual cash available to owners. Use alongside ROE and ROIC for complete analysis.

Net Income: $435.0M →

The numerator in ROE. Understanding net income trends helps explain ROE changes over time.
