Basically what the last thread said: the typical pattern is to buy a company, load it up with debt and cut expenditure to make all of the revenue graphs trend up for a few years then sell it to unwary public investors and walk away with a huge profit.

A lot of them end up collapsing under the debt a few years later, plus the heavy cutting of capital expenditure (“capex”) leads to a long term declining revenue as they are no longer investing in new products.
