Item 2.01 Completion of Acquisition or Disposition of Assets.

On July 3, 2012, Wesco Aircraft Holdings, Inc., a Delaware corporation (the “Company”), together with Wesco Aircraft Europe, Ltd., a private limited company incorporated in England and Wales (“Wesco Europe,” and together with the Company, the “Buyers”), completed its previously announced acquisition (the “Acquisition”) of substantially all of the assets of Interfast Inc., an Ontario Corporation (“Interfast”). The Acquisition was consummated pursuant to the terms of an Asset Purchase Agreement (the “Asset Purchase Agreement”) dated May 23, 2012, by and among the Buyers and Interfast.

Pursuant to the terms of the Asset Purchase Agreement, the Buyers paid Interfast an aggregate cash purchase price of approximately CDN$134.0 million at the closing of the Acquisition (approximately US$132.4 million based on an exchange rate of CDN$1.00 to US$0.9879 on July 3, 2012), which amount is subject to certain customary adjustments described in the Asset Purchase Agreement. A portion of the purchase price has been placed into an escrow account that will be used to satisfy certain rights to indemnification and other payments as provided in the Asset Purchase Agreement. The Company funded the Acquisition through $95.0 million in borrowings under its existing $150.0 million revolving credit facility, with the remainder paid from cash on hand.

Interfast is a Toronto-based value-added distributor of specialty fasteners, fastening systems and production installation tooling for the aerospace, electronics and general industrial markets. Interfast has a global presence working with both OEM (original equipment manufacturers) and MRO (maintenance, repair and overhaul) businesses to deliver proactive and innovative fastener-based solutions for a broad base of applications.

The foregoing description of the Asset Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the Asset Purchase Agreement, which the Company intends to file as an exhibit to its Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2012.
