Ørsted — Capital/Financing Update 2013

Jun 6, 2013

DONG Energy's unit interest in one of its major assets, the Norwegian gas field
Ormen Lange, has increased from 10.34% to 14.02%.

The increase in DONG Energy’s unit interest is based on an agreed
redetermination process initiated by the Ormen Lange partners and concluded in
June 2013 in the form of an independent external expert ruling.

Ormen Lange is a unitised field governed by three production licenses. The
purpose of the redetermination process carried out has been to review and,
where relevant, revise and re-allocate each Ormen Lange partner’s equity share
and capex in the Ormen Lange unit. This on the basis of reservoir performance
and updates after the field began producing in 2007.

DONG Energy’s higher unit interest is expected to take effect as of 1 July 2013.

The higher unit interest from this date will have a positive impact on DONG
Energy’s EBITDA and reserves going forward. As a consequence of the higher unit
interest, DONG Energy will receive additional volumes and be charged a higher
share of investments regarding previous years. This catch-up effect will mainly
affect 2013-2015.

DONG Energy's reserve base will increase by approximately 75 million barrels of
oil equivalents.

As a consequence of the increased unit interest, DONG Energy's EBITDA outlook
for 2013 is raised from DKK 11.5-12.5 billion to DKK 13-14 billion.

Furthermore, the expectation for net investments in 2013-2014 is increased from
DKK 25-30 billion to be in the level of DKK 30 billion due to the catch-up
effect regarding Ormen Lange.
