HAMPSTEAD, Md. — Jos. A. Bank withdrew its $2.3 billion offer to buy rival Men’s Wearhouse.

Shares of Men’s Wearhouse dropped almost 7 percent in premarket trading today.

Jos. A. Bank made an unsolicited offer of $48 per share for Men’s Wearhouse Inc. in September. Men’s Wearhouse rejected the bid in October, calling it “opportunistic” and “inadequate.”

In late October Jos. A. Bank Clothiers Inc. announced that it would terminate its bid by Nov. 14 if there continued to be no discussions on the proposal. The company says it still believes that a deal could be in the best interest of both companies’ shareholders.

An e-mail was sent seeking comment from Men’s Wearhouse.

Jos. A. Bank had previously said it would be open to raising its offer if allowed to assess whether an increased bid is justified. But Men’s Wearhouse wouldn’t give the company access to nonpublic information.

Today, Jos. A. Bank said that if the board of Men’s Wearhouse decides in the future that it wants to discuss a potential acquisition, or if circumstances otherwise change, that it may consider whether a new bid for its rival is warranted.
