COTT ANNOUNCES COMPLETION OF ACQUISITION OF PRIMO WATER CORPORATION AND WITH CLOSING THE SALE OF S&D COFFEE AND TEA TO WESTROCK COFFEE ON FEBRUARY 28^TH TRANSITIONS INTO A PURE-PLAY WATER SOLUTIONS PROVIDER

Cott to Rebrand its Corporate Name to Primo Water Corporation and Assume the Ticker PRMW on the NYSE and TSX

TAMPA, FL – March 2, 2020 – Cott Corporation (NYSE:COT; TSX:BCB) (the “Company” or “Cott”), today announced the completion of the acquisition of Primo Water Corporation (“Primo”), a leading provider of water dispensers, purified bottled water, and self-service refill drinking water in the U.S. and Canada.

The acquisition of Primo is consistent with Cott’s strategy of transitioning to a pure-play water solutions provider. Primo is a growing business with over $300 million in 2019 revenues. The acquisition adds further density to the distribution platform of Cott’s existing North American business by adding leading scale water solutions businesses to its portfolio. The transaction is expected to increase revenue growth and EBITDA margins, be accretive to earnings per share and deliver a cash on cash IRR above our cost of capital.

Cott has conducted an exchange offer by its wholly-owned subsidiary, Fore Acquisition Corporation (“Purchaser”), for all of the outstanding shares of common stock of Primo. The consideration is $14.00 per share, payable in cash, stock, or a combination thereof at the election of Primo’s stockholders, subject to the terms of the merger agreement. The transaction values Primo at approximately $775 million.

As a part of the transaction, Cott will change its name to Primo Water Corporation and its common shares will trade under the ticker PRMW on the NYSE and the TSX.

“The Primo acquisition is another great step in our strategy to become a pure-play water solutions provider with financial metrics more in line with our peers,” said Tom Harrington, Cott’s Chief Executive Officer. “We firmly believe that our combined businesses will drive significant value for our shareholders over the coming years,” continued Mr. Harrington.

Deutsche Bank Securities Inc. acted as financial advisor to Cott and Faegre Drinker Biddle & Reath LLP and Goodmans LLP provided legal counsel to Cott. Goldman Sachs acted as financial advisor to Primo and K&L Gates LLP provided legal counsel to Primo.

Exchange Offer Details

The depositary and paying agent for the exchange offer has advised that, as of 5:00 p.m., New York City time, on February 28, 2020, the expiration of the exchange offer, 32,716,138 shares of common stock of Primo were tendered pursuant to the exchange offer, representing approximately 81.1% of the issued and outstanding shares of common stock of Primo. The condition to the exchange offer that at least a majority of the issued and outstanding shares of Primo (as determined pursuant to the merger agreement) be validly tendered and not validly withdrawn and all other conditions to the exchange offer have been satisfied. Accordingly, Purchaser has accepted payment and will promptly pay the depositary for all validly tendered shares.

Following Purchaser’s acceptance of the Primo shares tendered in the exchange offer, Cott completed the acquisition of Primo on March 2, 2020 through a merger under Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”). All remaining shares of Primo common stock not tendered pursuant to the exchange offer (other than shares of Primo common stock (a) held in the treasury of Primo or owned by any direct or indirect wholly owned subsidiary of Primo, (b) owned by Purchaser, Cott or any direct or indirect wholly owned subsidiary of Cott, and (c) in respect of which appraisal rights were perfected in accordance with Section 262 of the DGCL) were canceled in the merger and converted into the right to receive the merger consideration in the same amounts offered in the exchange offer.

ABOUT COTT CORPORATION

Cott is a pure-play water solutions provider with a leading volume-based national presence in the North American and European home and office delivery industry for bottled water, a top five position across point of use or filtration within our 21-country footprint as well as leading positions in water dispensers, purified bottled water, and self-service refill drinking water in the U.S. and Canada. Our platform reaches over 2.5 million customers across North America and Europe and is supported by strategically located sales and distribution facilities and fleets, as well as wholesalers and distributors. This enables us to efficiently service residences, businesses, hotels and motels, small and large retailers and healthcare facilities.

Non-GAAP Measures

To supplement its reporting of financial measures determined in accordance with GAAP, Cott utilizes certain non-GAAP financial measures. Because Cott uses these adjusted financial results in the management of its business, 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. With respect to our expectations of performance of Primo as it is being integrated, reconciliations of 2020 estimated adjusted EBITDA, earnings accretion and cash on cash IRR are not available, as we are unable to quantify certain amounts that would be required to be included in the relevant GAAP measures without unreasonable effort. We expect that the unavailable reconciling items, which primarily include taxes, interest costs that would occur if the company issued debt, costs to capture synergies and phasing of capex, could significantly affect our financial results. These items depend on highly variable factors and any such reconciliations would imply a degree of precision that would be confusing or misleading to investors. We expect the variability of these factors to have a significant, and potentially unpredictable, impact on our future GAAP financial results. 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.
