LAFAYETTE - Lafayette-based Wabash National Corp.'s (NYSE: WNC) proposed acquisition of Goshen-based Supreme Industries Inc. (NYSEMKT: STS) is moving forward. The $364 million deal has cleared a federal antitrust review period.

The acquisition, announced in early August, was required to undergo a waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, or HSR Act. Wabash National is currently in the midst of its $21 per share tender offer for all outstanding shares of Supreme Industries common stock.

The company says the tender offer is set to expire on September 27, unless an extension is made. The acquisition remains subject to additional closing conditions, however Wabash National expects the deal to close by the end of the year.
