Diageo signs agreement with Pernod to buy Bushmills

Diageo has entered into an agreement with Pernod to purchase Bushmills, the world’s second largest Irish whiskey brand, for approximately £200 million. The acquisition of Bushmills represents an important opportunity for Diageo as Irish whiskey is a category in which, currently, Diageo does not participate. Diageo expects that the proposed acquisition will be economic profit positive during the fourth full year after completion using a 9% weighted average cost of capital.

In addition Pernod has granted Diageo an exclusive no cost option to purchase Allied Domecq’s Montana wine business with the exception of the Corbans, Stoneleigh and Church Road wine brands for 11 x 2004 contribution after marketing expenditure (CAMP). The purchase price, of approximately £ 320 million, may be adjusted to reflect information relating to the Montana CAMP which will be available following completion of the acquisition of Allied Domecq by Pernod. Diageo will exercise the option subject to determining that the acquisition of Montana can achieve appropriate growth and returns for shareholders.

The agreements are conditional upon the successful completion of Pernod’s agreed bid for Allied Domecq which Pernod and Allied Domecq have both stated they expect to occur on 26 July 2005. Both acquisitions would also be subject to regulatory clearance and are expected to close in late 2005 or early in 2006.

Under a separate agreement Diageo has undertaken to cease discussions with any third party in connection with any of the assets or businesses currently owned by Allied Domecq and not to (and to procure that none of its concert parties will) acquire or dispose of any shares in Allied Domecq without Pernod’s consent. This undertaking falls away on completion of the acquisition of Allied Domecq by Pernod

Diageo’s financial position remains strong and therefore notwithstanding both of these acquisitions Diageo will recommence the share buy back programme from tomorrow.

Paul Walsh, Chief Executive of Diageo commented:

‘Since 2000 Diageo has built a focused premium drinks company which is now a world leader. The business has grown organically and through targeted acquisitions. The acquisition of Bushmills and the option we have to acquire Montana continues that strategy.

‘The acquisition of Bushmills is a particularly pleasing opportunity. This is one of the industry’s oldest Irish whiskey brands and gives Diageo, for the first time, an important presence in this growing category. Montana is one of the leading New Zealand wine brands and the number one New Zealand export brand. The option gives us the opportunity to establish whether it could deliver the same growth that we have seen from our existing wine business.’

UBS Investment Bank is acting as financial advisor to Diageo. Slaughter and May is acting as legal advisor.

Notes to editor:

Diageo has been a lead player in the consolidation of the global drinks industry. In December 1997 Diageo plc was formed through the merger of Guinness and Grand Met, creating with that merger the world’s leading spirits company, United Distillers and Vintners. In 2000 Diageo merged its spirits, wine and beer businesses followed in December 2001 by the acquisition of certain key businesses of the Seagram Company Ltd. Diageo now owns market leading spirits, wine and beer brands.

In 1997 key brands retained from Guinness PLC included: Guinness, Johnnie Walker, Gordon’s, Tanqueray and Bell’s. While key brands retained from GrandMet included: Smirnoff, J&B, Baileys, Cuervo, Beaulieu Vineyard and Blossom Hill. In 2001 we augmented our priority brand portfolio through the acquisition of Captain Morgan, Crown Royal, Sterling Vineyards, Cacique, Myers Rum, Bulleit Bourbon, Seagram’s 7 and Seagram’s VO. And in 2004 we went on to acquire Ursus vodka and the Chalone Wine Group.

Diageo trades in some 180 markets around the world and is listed on both the New York Stock Exchange (DEO) and the London Stock Exchange (DGE). For more information about Diageo, its people, brands and performance, visit us at www.diageo.com
