On February 25, 2014, Darling International Inc.

The information contained in this Current Report, including Exhibit 99.1, is being furnished pursuant to Item 7.01, and the information contained therein shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, or otherwise subject to the liabilities under that Section.

{This current report, including Exhibit 99.1, contains forward-looking statements regarding the business operations and prospects of Darling International and industry factors affecting it. These statements are identified by words such as “may,” “will,” “begin,” “look forward,” “expect,” “believe,” “intend,” “anticipate,” “should,” “potential,” “estimate,” “continue,” “momentum” and other words referring to events that may occur in the future. These statements reflect Darling International’s current view of future events and are based on its assessment of, and are subject to, a variety of risks and uncertainties beyond its control, including the Company’s ability to successfully integrate and operate Rothsay and Darling Ingredients International, disturbances in world financial, credit, commodities, stock markets and climatic conditions; unanticipated changes in national and international regulations affecting the Company’s products; a decline in consumer confidence and discretionary spending; the general performance of the U.S. and global economies; global demands for bio-fuels and grain and oilseed commodities, which have exhibited volatility, and can impact the cost of feed for cattle, hogs and poultry, thus affecting available rendering feedstock and selling prices for the Company’s products; risks associated with the renewable diesel plant in Norco, Louisiana owned and operated by a joint venture between Darling International and Valero Energy Corporation, including possible unanticipated operating disruptions and marketing challenges; risks relating to possible third party claims of intellectual property infringement; economic disruptions resulting from the European debt crisis; continued or escalated conflict in the Middle East; and the Company’s relatively high level of indebtedness, each of which could cause actual results to differ materially from those indicated in the forward-looking statements. Other risks and uncertainties regarding Darling International, its business and the industry in which it operates are referenced from time to time in the Company’s filings with the Securities and Exchange Commission. Darling International is under no obligation to (and expressly disclaims any such obligation to) update or alter its forward-looking statements whether as a result of new information, future events or otherwise.}
