Performance in the three months ended March 31, 2010
(Comparative figures for the same period of last year are shown in brackets)

- ALK's vaccine sales grew by 10% in local currencies in Q1
- Total revenue increased by 13% to DKK 558 million (493)
- Operating profit before depreciation and amortization (EBITDA) increased to
DKK 136 million (96)
- Operating profit (EBIT) increased by 48% to DKK 114 million (77)
- Profit for the period was DKK 75 million (55)

ALK outperformed both sales and earnings expectations in Q1. The sales growth
was broadly based, and was mainly driven by sales of GRAZAX® in Northern and
Central Europe, injection-based vaccines in Germany, drop-based vaccines in
France and adrenaline in the UK.

As expected, ALK received net operating income of DKK 16 million in connection
with the initiation by ALK's collaborative partner, Merck, of treatment of
patients in two Phase III clinical studies of the tablet vaccine against
ragweed. Payments from Merck during the same period of last year amounted to
DKK 8 million.

ALK has proposed to acquire the largest allergy vaccine company in the
Netherlands. Assuming shareholder approval at an extraordinary general meeting,
the acquisition is expected to be made with effect from July 1, 2010.

ALK expects Germany to implement a healthcare reform which will include an
increase of mandatory sales rebates on pharmaceuticals eligible for
reimbursement. If implemented, the proposed reform will adversely affect ALK's
sales and earnings.

Outlook for 2010
For the 2010 financial year and excluding any acquisitions, ALK retains its
forecast of growth in allergy vaccine sales of 5-8% in local currencies and a
minor improvement of EBITDA and EBIT. The anticipated adverse effects of the
German healthcare reform are reflected in the forecasts.

If the acquisition of the Dutch allergy vaccine company goes ahead as planned,
it is expected to contribute favourably to ALK's sales and earnings in 2010.
Once the transaction has been completed, ALK will specify the impact on
operating results.
