Press Release

Share Repurchase Program

Cott announced its plans to commence, subject to compliance with the annual limits established by the Toronto Stock Exchange (“TSX”), a share repurchase program for up to $35 million in common shares over a 12 month period. Cott’s common shares may be purchased in open market transactions and privately negotiated repurchases under the program through either a 10b5-1 automatic trading plan or at management’s discretion in compliance with regulatory requirements, and given market, cost and other considerations.

Subject to completion of appropriate filings with and approval by the TSX, repurchases will be made through the facilities of the TSX, the New York Stock Exchange (“NYSE”), or by such other means as may be permitted by the TSX and/or the NYSE. The rules and policies of the TSX contain restrictions on the number of shares that can be repurchased over a 12-month period, and also contain restrictions on the number of shares that can be purchased on any given day, based on the average daily trading volumes of the common shares on the TSX. Similarly, the safe harbor conditions of Rule 10b-18 impose certain limitations on the number of shares that can be purchased on the NYSE per day.

“We are pleased to be able to announce this share repurchase program as an excellent way to return value to our shareowners,” continued Mr. Fowden.

There can be no assurance as to the precise number of shares that will be repurchased under the share repurchase program, or the aggregate dollar amount of the shares actually purchased. Cott may discontinue purchases at any time, subject to compliance with applicable regulatory requirements. Shares purchased pursuant to the share repurchase program will be cancelled.

Defined Terms

Certain defined terms used in this press release include the following. “GAAP” means U.S. generally accepted accounting principles. “EBITDA” means GAAP earnings (loss) before interest, taxes, depreciation and amortization. “Adjusted EBITDA” means GAAP earnings (loss) before interest, taxes, depreciation and amortization, excluding purchase accounting adjustments, integration expenses, restructuring and asset impairments. See the accompanying reconciliation of Cott’s EBITDA and Adjusted EBITDA to its GAAP net income, as well as the “Non-GAAP Measures” paragraph below.

Non-GAAP Measures

Cott supplements its reporting of revenue determined in accordance with GAAP by excluding the impact of foreign exchange to separate the impact of currency exchange rate changes from Cott’s results of operations and, in some cases, by excluding the impact of the Cliffstar acquisition. Cott supplements its reporting of earnings before interest, taxes, depreciation and amortization by excluding Cliffstar purchase accounting adjustments, integration expenses, restructuring and asset impairments to separate the impact of these items from the underlying business. Because Cott uses these adjusted financial results in the management of its business and to understand business performance independent of the Cliffstar acquisition, management believes this supplemental information is useful to investors for their independent evaluation and understanding of Cott’s underlying business performance and the performance of its management. The non-GAAP financial measures described above are in addition to, and not meant to be considered superior to, or a substitute for, Cott’s financial statements prepared in accordance with GAAP. In addition, the non-GAAP financial measures included in this earnings announcement reflect management’s judgment of particular items, and may be different from, and therefore may not be comparable to, similarly titled measures reported by other companies.

Forward-looking statements involve inherent risks and uncertainties and Cott cautions you that a number of important factors could cause actual results to differ materially from those contained in any such forward-looking statement.
