You want a low EV/EBITDA number. A high EV to EBITDA means there is a ton of debt and no cash in the business and/or low operating profits.
So the EV/EBITDA multiple would be positively realted to growth in EBITDA and poitively related to FCFF, since you net out the cash to calculate the EV, which makes the numerator smaller.
I think, anyway.
