Serial acquirer
Factual definition
A serial acquirer is a company that makes acquisitions repeatedly as part of its strategy. It may integrate acquired businesses or leave them operating with substantial independence; acquisition frequency alone does not establish skill.
Serial acquirer in round numbers
Hypothetical: an acquirer buys ten businesses at a combined acquisition enterprise value equal to 6× their aggregate annual earnings before interest, taxes, depreciation and amortization (EBITDA), measured on a consistent basis. If the group is later valued at 10× that same EBITDA, the assumed multiple rises by four turns.
Holding earnings fixed, this implies an enterprise-value uplift before transaction costs and other adjustments. It is not a realized profit or investor return; debt, fees, and the eventual sale price still matter.

Acquisitions can hide a shrinking existing business
Hypothetical: the businesses owned at the start of the year generated US$100m of revenue last year and US$95m this year. A newly acquired business contributes another US$20m of recognized revenue after closing.
Reported revenue is US$115m, up 15% from US$100m. But the existing businesses shrank 5%; the acquisition contribution more than offset that decline.
Keep the acquisition date and comparison basis explicit when building the bridge. Adding the acquired company’s full-year revenue to a partial-year reported figure would mix periods.
The next question is why the original businesses lost US$5m: fewer customers, lower prices, smaller orders or a deliberate exit from unprofitable work. Buying another business does not answer that operating question.
