Pixar is to announce its fourth-quarter and full-year 2003 earnings later today. The results will be published at 5pm EST (10pm GMT).

Pixar's CEO is Steve Jobs, and his company's results come at the end of a good year, with Pixar fifth movie Finding Nemo becoming the biggest-selling animated movie ever, earning £339 million (£200m) in the US box office.

This follows news that Pixar has ended its distribution agreement with Disney, under which Pixar had agreed to produce five original computer-animated feature films for distribution by Disney. The deal, which was signed in 1997, was to end in 2005. Pixar must though produce two more movies for Disney under the existing contract – The Incredibles in 2004 and Cars in 2005.

Pixar has said it will now negotiate with other studios, with reports suggesting that both Warner Bros and 20th Century Fox are interested in distributing Pixar's movies.

Regarding the situation with Disney, Jobs said: "After ten months of trying to strike a deal with Disney, we're moving on. We've had a great run together – one of the most successful in Hollywood history – and it's a shame that Disney won't be participating in Pixar's future successes."

Speaking to The Times about Pixar last year, Jobs said: "We're the most successful animation studio in the world. "If you look at the box-office total for our last four films and compare it with Disney or DreamWorks’ last four films, our sales are over double theirs. It’s a wonderful thing."
