Acquisition valuations of withdrawn IPOs: When IPO plans turn into mergers

We examine the acquisition valuations of withdrawn-IPOs - private targets that are acquired after they file and then withdraw their IPOs - to examine how IPO registration and withdrawal affect valuations of withdrawn-IPOs in their subsequent mergers. We find that these “almost public” withdrawn-IPOs sell at a significant acquisition premium relative to comparable pure private targets that never file IPO registration and at acquisition valuations similar to comparable public targets. The premium persists only for withdrawn-IPOs that are acquired before their IPO withdrawals after other factors are controlled for. These findings confirm that there is a significantly positive (negative) valuation impact of IPO registration (IPO withdrawal) on withdrawn-IPOs' subsequent acquisitions. The two effects offset each other for withdrawn-IPOs that are acquired after their IPO withdrawals.
