Novo Nordisk A/S purchases B shares worth DKK 2.5 billion from Novo A/S as part of the on-going share repurchase programme

Bagsværd, Denmark, 3 May 2013 - Novo Nordisk A/S has today entered into an agreement to purchase 2,550,000 B shares (nominal DKK 1) of a value of DKK 2.5 billion from Novo A/S. This transaction is part of the on-going share repurchase programme of up to DKK 14.0 billion to be executed during a 12-month period beginning 31 January 2013. The transaction price is set to DKK 981.84 per share and has been calculated as the average market price from 1 May 2013 to 3 May 2013 in the open trading window following the announcement of Novo Nordisk's financial results for the first quarter of 2013.

Novo A/S will thereby readjust its ownership of Novo Nordisk A/S to 25.5%, equal to the level of ownership prior to the cancellation of treasury shares, which took place in April 2013.

Prior to the sale of B shares, the shareholding of Novo A/S in Novo Nordisk A/S corresponded to 26.0% of the share capital and 73.2% of the votes. Following the transaction, the shareholding of Novo A/S in Novo Nordisk A/S is 107,487,200 A shares (nominal DKK 1) and 32,762,800 B shares (nominal DKK 1), corresponding to 25.5% of the capital and 73.0% of the votes.

Henrik Gürtler, CEO of Novo A/S, said: "Following the recent cancellation of treasury shares, Novo A/S has realigned its shareholding in Novo Nordisk A/S to the level of just over 25%, which has been the desired minimum level since the demerger of Novozymes A/S in 2000. We remain a committed long-term majority shareholder of Novo Nordisk A/S."

As of 3 May 2013, Novo Nordisk A/S has repurchased B shares amounting to DKK 5.5 billion during the period beginning 31 January 2013 when taking this transaction with Novo A/S into account. Transactions related to Novo Nordisk's incentive programmes have resulted in a net sale by Novo Nordisk of 33,422 B shares in the period from 1 May
