Investopedia explains Like-For-Like Sales
Using like-for-like sales is a method of valuation that attempts to exclude any effects of expansion, acquisition, or other events that artificially enlarge the company's sales. For example, if you are trying to compare the turnover of company ABC from this year to last year, it makes sense to exclude from the equation any sales resulting from acquisitions this year.
