Force India are one of three teams yet to finalise their driver line-ups four days ahead of the start of testing.
Speaking at the launch of the VJM06 deputy team principal Bob Fearnley said: “The shareholders will make their decision in due course. We need to be very careful where we are going, and the shareholders will take as long as necessary.
“I expect we will announce the two remaining drivers before Barcelona.”
Jules Bianchi and Adrian Sutil are believed to be the two drivers in the running for the seat.
Fearnley added he expects the team to start the season as competitively as it ended 2013: “I like to think that we can start where we finished, it would be very nice to lead a few races, but perhaps that is a bit optimistic.
“We should certainly be looking at knocking on the door for podium positions again. That would finish off our five-year programme perfectly before we go into the new regulations in 2014.”
