Metrics are mathematically derived from official filings.
Margin Recovery Masks Underlying Volatility
Gross margin swung from 26.4% in 2024Q4 to 12.7% in 2026Q2, as per financial statements, while operating margin improved to 4.0% in 2026Q2 from 1.7% in 2024Q4, indicating cyclical recovery but persistent cost pressures.
The 10-quarter gross margin range of 10.6% to 26.4% reflects the pass-through of aluminum costs and energy volatility, with the latest quarter near the lower end. Operating margin of 4.0% in 2026Q2 is below the 10-quarter average of 5.1%, suggesting that despite record EBITDA, conversion margins remain compressed. Net margin of 5.3% in 2026Q2 was boosted by non-operating gains, as net income exceeded operating income, so investors should focus on operating margin as the cleaner measure of earning power.
ROIC Recovery Still Below Cost of Capital
ROIC improved to 2.8% in 2026Q2 from 0.8% in 2024Q4, as reported in financial statements, but remains well below the 8-10% typical for specialty aluminum peers, indicating capital efficiency is still recovering.
The 10-quarter ROIC trend shows a trough of 0.8% in 2024Q4 and a peak of 6.0% in 2026Q1, with the latest quarter at 2.8%. This suggests that while returns are improving, they remain insufficient to cover the cost of capital, likely due to the high fixed-cost base and heavy maintenance capex. ROE of 12.2% in 2026Q2 is higher than ROIC, reflecting the benefits of leverage, but the gap between ROE and ROIC highlights the risk of financial leverage amplifying returns.
Working Capital Cycle Lengthens on Inventory Build
Cash conversion cycle extended to 34 days in 2026Q2 from 17 days in 2024Q2, as per financial data, driven by higher DIO of 67 days and stable DSO, indicating inventory accumulation is consuming cash.
The CCC has been volatile, ranging from 17 to 43 days over the last ten quarters, with the latest reading at 34 days. DIO rose to 67 days in 2026Q2 from 66 days a year earlier, while DPO remained around 69 days, suggesting that inventory build-up is not being offset by extended supplier terms. This is consistent with the working capital drag seen in cash flow, where changes in working capital consumed $219M in 2026Q2, indicating that operational efficiency is being challenged by inventory management.
Leverage Eases but Debt Service Remains Tight
Debt-to-equity fell to 1.53 in 2026Q2 from 2.69 a year earlier, as reported in financial statements, while interest coverage improved to 3.93x from 2.01x, indicating a strengthening but still leveraged balance sheet.
The D/E improvement is driven by a 54% rise in equity to $1.2B, but total debt of $1.9B remains substantial. Interest coverage of 3.93x in 2026Q2 is above the 10-quarter average of 2.5x, but the 2026Q1 reading of 273x appears anomalous and likely reflects a data error or one-time gain. D/EBITDA of 9.91x in 2026Q2 is elevated compared to peers like Alcoa (10.42x) and Kaiser (11.45x), but the trend is improving from 15.16x in 2025Q2, suggesting that deleveraging is progressing.
Liquidity Improves but Cash Buffer Remains Thin
Current ratio improved to 1.43 in 2026Q2 from 1.23 a year earlier, as per balance sheet data, but quick ratio of 0.61 indicates heavy reliance on inventory, leaving limited cushion under stress.
The current ratio of 1.43 is the highest in the last ten quarters, but the quick ratio of 0.61 suggests that inventory, which is subject to metal price volatility, is a significant component of current assets. Cash of $163M is modest relative to total debt of $1.9B, and the company's ability to weather a severe downturn would depend on access to credit lines, which are not disclosed. The improving trend in liquidity is positive, but the thin cash buffer warrants monitoring.
Misapplied Metric: Debt-to-Equity
The reported Debt/Equity of 2.00% in the data appears anomalous and contradicts the balance sheet's D/E of 1.53, as per financial statements, suggesting a data error that could mislead leverage assessments.
The most commonly misapplied ratio for CSTM is the headline Debt/Equity, which can be distorted by the timing of equity rebuilds and goodwill impairments. The 2.00% figure in the data is inconsistent with the balance sheet's D/E of 1.53, and the prior goodwill write-down of $415M artificially depressed equity in earlier periods. Instead, investors should use Debt/EBITDA and interest coverage, which better reflect the company's ability to service debt, and adjust for the pass-through nature of aluminum costs by focusing on Value-Added Revenue (VAR) to assess true leverage capacity.
