Prior research on IPO long-term performance focuses on three- to five-year post-issue periods and shows that the apparent IPO underperformance disappears when different risk exposures across IPO and mature firms are accounted for by using a Carhart (1997) factor model. We show that a sample of 7,487 U.S. IPOs between 1975 and 2014 continues to significantly underperform mature firms in terms of Carhart-alphas over two years, with underperformance peaking one year after going public. We apply a regression-based portfolio sorts approach (RPS) to explain one-year IPO underperformance using a multitude of market and firm characteristics in a statistically robust setting. Our RPS-model, that augments the Carhart-factors by firm characteristics related to investments, internationality, liquidity, and leverage, completely explains IPO underperformance. Our RPS-model even explains underperformance in the univariately most severely underperforming sub-samples in terms of firm size, time period, venture capital involvement, and IPO underpricing.
