Where Quest Diagnostics ranks

What the EV/EBIT tells you

What the whole business costs against its operating profit. Enterprise value is the market value plus borrowings and minority interests, less cash. EBIT is operating profit before interest and tax, with one-offs taken out. Unlike PE it is not moved by how a company is financed.

Leases are left out of debt for every company. Banks earn on their balance sheet, so EV/EBIT does not describe them.
