DirecTV generates earnings before interest, taxes, depreciation, and amortization (EBITDA) of approximately $4.5 billion, and potential buyers are offering 3.5 times that amount. That would translate into an offer of $15.75 billion, according to the report. If AT&T accepts such a low bid, it would lose over $50 billion when factoring in the total that it paid, including for DirecTV's debt that the telecommunications giant is still on the hook for.
