Asset Purchase Agreements.

On June 27, 2014, TriCan Tire Distributors Inc. (“TriCan”), an indirect wholly-owned subsidiary of American Tire Distributors Holdings, Inc. (“Holdings” or the “Company”) entered into an Asset Purchase Agreement (the “Trail Tire Purchase Agreement”) with Trail Tire Distributors Ltd., a corporation formed under the laws of the Province of Alberta (“Trail Tire”) and the shareholders and principals of Trail Tire, pursuant to which TriCan agreed to acquire the wholesale distribution business of Trail Tire. Trail Tire is a wholesale distributor of tires, tire parts, tire accessories and related equipment in Canada.

On June 27, 2014, TriCan entered into an Asset Purchase Agreement (the “Extreme Purchase Agreement”) with Extreme Wheel Distributors Ltd., a corporation formed under the laws of the Province of Alberta (“Extreme”) and the shareholder and principal of Extreme, pursuant to which TriCan agreed to acquire the wholesale distribution business of Extreme. Extreme is a wholesale distributor of wheels and related accessories in Canada.

Simultaneous with the signing of the Trail Tire Purchase Agreement and the Extreme Purchase Agreement, the parties closed both acquisitions for aggregate cash consideration of approximately $27.3 million. The aggregate cash consideration was funded through borrowings under the Company’s existing ABL credit facility. The Trail Tire and Extreme purchase prices are both subject to certain post-closing adjustments, including, but not limited to, working capital adjustments. Neither Holdings, TriCan, nor any of their affiliates has had a material relationship with Trail Tire or Extreme, other than in respect to the purchase agreements.
