The Worst-Performing Large IPOs: Where Sector Mattered More Than Deal Size
Three of the 10 largest IPOs were negative at the 5-year mark, and a fourth spent most of its first five years below its offer price. In each case, the company was influenced by sector dynamics.
Saudi Aramco is down 13% since its December 2019 offer price, the worst total return in the group, according to investing.com data. The company listed at the end of a decade in which energy's share of global equity indexes declined, and oil prices have not consistently supported the valuation implied at the IPO price.
SoftBank Corp (TSE:9434), the Japanese telecom subsidiary, not SoftBank Group, fell 15% on its first day of trading in December 2018, according to FactSet data, and spent most of the following five years below its offer price. Total return from the split-adjusted offer price of 150 JPY: +43% as of May 2026, according to FactSet data. A mature telecommunications business with limited growth levers attracted limited long-term capital.
NTT DoCoMo (TSE:9437) gained 47% in its first year after its October 1998 IPO, then fell sharply with the broader telecom sector. By year three, it was down 48% from the IPO price. NTT took the company private in 2020.
Enel SpA raised $16.5 billion in its 1999 Italian privatization. Total return in euros from the split-adjusted offer price of €7.31: +31% as of May 2026, according to FactSet data.
The five companies with the highest total returns, Visa, Meta, AIA Group, ICBC, and General Motors, are all financials, technology, or consumer companies. The four weakest performers span energy, telecom, and utilities.
