Earnings management within IPO firms and private equity backing : Earnings management's affect on stock market reaction and IPO's adjustable offering

In order to boost the exit value, it is not uncommon that issuers report earnings in excess of cash flow generated by its operations at the initial public offering (IPO). The discretionary activity of performing earnings management can mislead investors about the intrinsic value of the newly public firm. Within this study, I examine how earnings management will affect the stock market reaction upon the lockup expiration date, the IPO adjustable offering size, and how the backing of private equity or venture capital (PEVC) affects earnings management tendencies within IPO firms. Using a unique, hand-collected dataset of 56 Swedish newly public firms from 2007 - 2014, I show that IPO firms (i) manage their earnings at the full fiscal year prior to the IPO and that earnings management will result in a negative stock market reaction upon the lockup expiration date. More importantly, I show that (ii) high adjustable offerings do not affect this relationship indicating that earnings management has no impact on the adjustable part of the offering size within IPOs. I also find that (iii) IPO firms backed by PEVC firms are more eager to manipulate their earnings, and (iv) highly reputable PEVC firms do not mitigate the manipulation of earnings within IPO firms. The results taken together suggest that studying the stock market reaction on the lockup expiration date is important for manipulative IPO firm detection, and that a participation in IPOs backed by PEVC firms must be done with caution
