Gogo Inc., which provides Internet service on airline flights, failed to connect with the stock market Friday.
The company is growing rapidly, but it is also unprofitable. And the initial public offering of stock came at the end of a tumultuous week on Wall Street, which may have unnerved investors. The Dow Jones industrial average tumbled 560 points on Wednesday and Thursday.
On Friday, Gogo's stock fell 5.8 percent in its first day on the Nasdaq.
The company, which is based in Itasca, Ill., uses a network of cell towers to provide Internet access for passengers on more than 1,900 planes. Customers include four of the five biggest U.S. airlines — United, Delta, American and US Airways — which charge passengers for Internet access. Southwest Airlines uses a rival Wi-Fi provider, Row 44.
Gogo is going public as it seeks to expand its service to international flights. CEO Michael Small said Friday that the company decided to sell the shares now because its planned international expansion "is becoming real."
The IPO will help pay for that expansion, Small said in an interview, and "the credibility of being a public company will help us with airlines around the world." The IPO raised $187 million.
In March, Gogo signed an agreement with Delta to outfit the airline's entire international fleet of 170 planes with satellite-based service. It also wants to put its service on planes operated by foreign carriers.
While Gogo says its service is available on 81 percent of all Wi-Fi-enabled planes in North America, only about 6 percent of passengers pay for Internet.
