TransDigm Group Incorporated Commences Tender Offer for All Shares of Aerosonic Corporation

TransDigm Group Incorporated (“TransDigm”) (NYSE: TDG) and Aerosonic Corporation (“Aerosonic”) (NYSE MKT: AIM) today announced that TransDigm’s indirect wholly owned subsidiary, Buccaneer Acquisition Sub Inc. (“Purchaser”), has commenced a tender offer to acquire all of the outstanding shares of Aerosonic common stock for $7.75 per share in cash, without interest and less any applicable withholding taxes (the “Offer”). The Offer is being made pursuant to the terms of the previously announced definitive merger agreement (the “Agreement”) entered into between TransDigm, Purchaser and Aerosonic on April 19, 2013.

If the Offer is successfully completed, pursuant to the terms of the Agreement, TransDigm expects to acquire any of the Aerosonic common shares not tendered in the tender offer through a merger transaction in which the remaining shares of Aerosonic are converted into a right to receive the same consideration per share as paid in the Offer.

The Offer is subject to customary closing conditions, including valid tender of shares representing at least a majority of Aerosonic’s then outstanding shares on a fully diluted basis. There is no financing condition to the Offer.

The Offer is scheduled to expire at 12:00 Midnight, New York City time, on Tuesday, June 4, 2013, unless otherwise extended.

As contemplated by the Agreement, Aerosonic, with the assistance of its independent advisors, will solicit superior proposals from third parties until May 29, 2013. Aerosonic does not anticipate disclosing any developments regarding this process unless and until its Board of Directors makes a decision with respect to a potential superior proposal. There is no assurance that this process will result in a superior proposal. TransDigm will terminate the Offer if Aerosonic accepts a superior proposal and terminates the Agreement in accordance with its terms.

Today, TransDigm is filing with the Securities and Exchange Commission (the “SEC”) a tender offer statement on Schedule TO, including an offer to purchase and related letter of transmittal, setting forth in detail the terms of the Offer. In addition, Aerosonic is filing with the SEC today a Solicitation/Recommendation Statement on Schedule 14D-9 setting forth in detail, among other things, the recommendation of Aerosonic’s Board of Directors that Aerosonic stockholders tender their shares pursuant to the Offer.

Copies of the offer to purchase, letter of transmittal and other related materials, including the Solicitation/Recommendation Statement, are available free of charge to Aerosonic stockholders from Georgeson Inc., the Information Agent for the Offer, at (800) 868-1390 (toll-free).
