Yes, the corporation can be a party to a contract as long as the corporation ratified the contract once it did come into existence. To be safe, you would sue the company that entered into the contract, the new corporation and anybody else. If your company is a corporation, then you cannot sue, you will need to hire an attorney.
"Ratification can be determined by 1) the minutes of the new corp. expressly ratifying the contract, and/or the course of conduct of the parties in which the parties accepted the benefits of performance of the parties as provide for under the terms of the contract. A contracting party can be estopped from claiming that a contract is is enforceable after they received the benefits of the agreement and/or conducted themselves as if they was an enforecable contract.

As previously stated in the other answers A corporation may be liable if they ratified the contract. Further, you should note that who ever did sign the contract as Corp A may be able to be held personally liable for the breach.
In terms of the effect on Corp B this is dependent on the relatedness of the parties in the contract and whether the Corp B's performance was conditioned on Corp A's performance; more facts are needed to adequately analyze this question.
