I think they did sign another contract but look at it this way - they can make just about the same amount of money, or more releasing Cheryl solo albums. 3 Words will probably sell a million copies by the end of the year. I don't know, if the contract does exist and the girls didn't want to get back together I don't think the label would be too upset. It'd be different if Cheryl was a flop, her albums and singles flopped, etc..
