FAST Acquisition Corp, a blank-check firm, refused to end its merger with Fertitta Entertainment, owned by billionaire Tilman Fertitta, saying the termination initiated by Fertitta is invalid. Fertitta Entertainment had moved to terminate the deal, first agreed in February, on Wednesday. FAST said on Thursday Fertitta’s delay in delivering its financial statements is why the deal has not been closed by the termination date, and so it has no right to unilaterally end the merger agreement.
