EV/EBITDA understand, companies, structure

CFA4Techie

Quick question. I know they say you should use EV/EBITDA for capital intensive type company's but I don't understand why. If you want to compare companies that are capital intensive and that's a major part of their business, wouldn't you want to use a multiple that includes an interest charge? Or is it because capital structure can be changed so best to exclude it?

Thanks
