The Cost That Does Not Shrink
Why the cost of maintaining a stock exchange listing weighs in inverse proportion to size, and the point from which delisting pays for itself
The thesis
The cost of maintaining a listed company is practically fixed, and therefore weighs in inverse proportion to size. For Ambev, the present value of that cost is equivalent to three thousandths of one per cent of the company. For a company with a market value of twelve million, the same cost is equivalent to forty-four per cent, and that is where the decision to go private makes itself
What the study establishes
The number of companies listed on B3 fell from 416 in October 2023 to 368 in October 2025, forty-eight delistings in three years and no IPO since 2021
Below roughly fifty-four million in market capitalisation, with a quarter of the shares in free float, a going-private tender offer pays for itself on registration-cost savings alone
Across nine going-private tender offers analysed, the median premium to the share price was 24.8%, ranging from 2.6% to 57.9% depending on the nature of the transaction
