Capital Intensity

The CAPEX / EBITDA ratio compares capital expenditures with operating earnings as measured by EBITDA. It indicates the company’s capital intensity: the higher the ratio, the larger the share of operating cash flow that must be reinvested to maintain or expand productive capacity. A low ratio, by contrast, suggests less dependence on heavy investments, leaving more room for debt reduction or shareholder returns.

Enterprise value

Enterprise Value reflects the total value of a company from the perspective of a buyer. It equals market capitalization plus net debt (financial debt minus cash). Unlike market cap alone, it accounts for all capital providers — both shareholders and lenders.
