Jos. A. Bank Clothiers, based in Hampstead, Md., said in a statement it was "disappointed" that its request for information was turned down and reaffirmed that it would drop its offer if "good faith discussions" are not held by Nov. 14.

Jos. A. Bank made its unsolicited offer of $48 per share for Men's Wearhouse in September, and the following month Men's Wearhouse rejected the bid, calling it "opportunistic" and "inadequate."
On Monday, Men's Wearhouse said its board met with external financial and legal advisers and determined with them that it wasn't in its shareholders' best interest to give Jos. A Bank access to the information.
