Blue Bird Corporation, formerly named Hennessy Capital Acquisition Corp., announced today the extension of its previously announced offer to exchange (the “Offer”) up to a maximum of 5,750,000 of its outstanding warrants (the “Warrants”) for shares of Company common stock (the “Shares”) at an exchange ratio of 0.1 of a Share for each Warrant validly tendered and not withdrawn (approximately one Share for every ten Warrants tendered). The Offer has been extended until 12:00 midnight, New York City time, at the end of the day on March 2, 2015, unless further extended by the Company.

The Offer was previously scheduled to expire at 12:00 midnight, New York City time, at the end of the day on February 26, 2015. As of February 23, 2015, 283,366 Warrants have been tendered and not withdrawn and the last reported trading price of the Warrants was $0.75 per Warrant.

The terms and conditions of the Offer are set forth in the Amended and Restated Offer to Exchange, dated January 21, 2015 (as it may be amended or supplemented from time to time, the “Offer to Exchange”), the related Amended and Restated Letter of Transmittal and other Offer materials that were filed on January 22, 2015 with the U.S. Securities and Exchange Commission (the “SEC”) and were distributed to Warrant holders. The “Business Combination” referenced in the Offer to Exchange was consummated on February 24, 2015, thereby satisfying one of the conditions to the Offer. Except for the extension of the Offer and the satisfaction of the “Business Combination” condition to the Offer described in the Offer to Exchange and related materials, all of the material terms and conditions of the Offer remain unchanged.
