The other shortlisted bidders are Greenwich Leisure Ltd and Parkwood Leisure, both of which have largely worked with local authorities in running leisure centers.
"We are delighted by the caliber of shortlisted candidates to operate two of London's best sporting facilities," Peter Tudor, director of venues at the Olympic Park Legacy Company (OPLC), said in a statement.
The 269 million pound aquatics center, with its distinctive sting-ray shaped roof, was completed this week and was the focus of London's one-year-to-go celebrations.
Designed by Iraqi-born architect Zaha Hadid, it will be reduced in size from 17,500 seats to 2,500 when it re-opens in 2014. Experts say it will need subsidies if it is to fulfill the OPLC's ambition of both elite and community use, despite an expected 800,000 visits a year.
The copper-clad 44-million-pound handball arena, to be called the multi-use arena after the Games, is to be a center for community sport and will also be used to host a range of sporting, community, entertainment, cultural and business events.
The 7,500-seat arena, which will also re-open in 2014, is expected to attract up to 600,000 visits a year.
Both are part of the OPLC's plans to lure investment into the site, to be re-named the Queen Elizabeth Olympic Park.
Greenwich Leisure is an employee-led charitable social enterprise which works mainly with local councils to operate more than 100 public leisure centers, including Crystal Palace, which stages Grand Prix international athletics events.
Parkwood Leisure specializes in the development and operation of leisure facilities on behalf of clients, while Serco works with national and local governments in the areas of health, transport, leisure, science, defense and education.
