Valuation
The Nov 6 close compared with the last 12 months of reported results (the four quarters to Sep 30, 2026). Tap a metric to see how it’s calculated.
Price-to-earnings (P/E)
5.3×The Nov 6 close ÷ diluted EPS over the last 12 months ($4.09)
The range covers daily P/E ratios from Oct 28, 2021 to Nov 6, 2026, each based on the previous 12 months of earnings.
CSTM trades at 5.3× its earnings over the last 12 months, below its 5-year median of 12.4×. In plain terms, buyers are paying about $5 for each $1 of profit from the past year. How to read P/E
Other valuation measures
- 0.3×Last 12 months’ revenue
Market value divided by revenue over the last 12 months. Useful when earnings are small or negative.
P/S = Market cap ÷ Revenue (last 12 months)Price-to-sales ratio - 2.2×Book value as of Sep 30, 2026
Price relative to accounting equity (book value) per share on the Sep 30, 2026 balance sheet. Asset-light companies often trade far above book value.
P/B = Price ÷ Book value per sharePrice-to-book ratio - 3.7×Last 12 months’ EBITDA
Enterprise value divided by EBITDA over the last 12 months. It compares companies with different amounts of debt.
EV/EBITDA = Enterprise value ÷ EBITDA (last 12 months)EV/EBITDA explained - 0.01Last 12 months’ EPS growth
The P/E divided by the growth in diluted EPS over the last 12 months (+404.9% on the 12 months before). It looks backward: near 1 means the P/E roughly matches last year’s growth. Sites that use analysts’ growth forecasts show a different PEG.
PEG = P/E ÷ EPS growth (%) = 5.3 ÷ 404.9 - 11.27%Last 12 months’ free cash flow
Free cash flow over the last 12 months as a share of the company’s market value: the cash the business generated for each dollar of stock.
FCF yield = Free cash flow (last 12 months) ÷ Market capFree cash flow - $4.62BAt the Nov 6 close
What it would cost to buy the whole business: the market cap at the Nov 6 close, plus debt, minus cash and short-term investments from the Sep 30, 2026 balance sheet.
