On December 3, 2013, the YRC Worldwide Inc. (the “Company”) entered into an At Market Issuance Sales Agreement (the “Sales Agreement”) with MLV & Co. LLC (the “Sales Agent”), under which the Company may sell up to the amount available for offer and sale under the currently effective Registration Statement on Form S-3 (Registration No. 333-159355) (the “Registration Statement”) of the Company’s common stock from time to time through the Sales Agent. The Sales Agent may sell the common stock by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415 of the Securities Act of 1933, as amended, including without limitation sales made directly on the NASDAQ Global Select Market, on any other existing trading market for the common stock or to or through a market maker. The Sales Agents may also sell the common stock in negotiated transactions, subject to the Company’s prior approval. The compensation to the Sales Agent for sales of common stock sold pursuant to the Sales Agreement will be an amount equal to 3.0% of the gross proceeds of shares of common stock sold, if any.

The Sales Agreement will terminate on the earliest of (1) the sale of all of the common stock subject to the Sales Agreement, or (2) termination of the Sales Agreement in accordance with its terms. The Sales Agreement contains customary representations, warranties and covenants. The Company has also agreed to provide the Sales Agent with customary indemnification rights.

This description of the Sales Agreement is qualified in its entirety by the text of the Sales Agreement which is attached hereto as Exhibit 1.1 and incorporated by reference.

On August 29, 2013, the Securities and Exchange Commission (the “Commission”) declared effective the Company’s Registration Statement. That Registration Statement permits the issuance, from time to time, by the Company of certain of its securities, including shares of the Company’s common stock, up to an aggregate initial offering price not to exceed $350,000,000. A prospectus supplement dated December 3, 2013 to be filed with the Commission contemplates the sale of up to 3,000,000 shares of the Company’s common stock from time to time in at-the-market offerings pursuant to the Sales Agreement described in Item 1.01 above.

Sales pursuant to the Sales Agreement will be made only upon instructions by the Company to the Sales Agents, and the Company cannot provide any assurances that it will issue any shares pursuant to the Sales Agreement.

In order to furnish certain exhibits for incorporation by reference into the Registration Statement, the Company is filing the Sales Agreement and an opinion the Company received from its counsel regarding the validity of the shares to be sold pursuant to the Sales Agreement, which opinion is attached hereto as Exhibit 5.1.
