Medivir’s board of directors has resolved to repurchase own shares

Stockholm, Sweden — Medivir AB (Nasdaq Stockholm: MVIR) today announce that
Medivir’s board of directors has resolved to use the authorisation given by the
annual general meeting regarding repurchases of Medivir class B shares.

The repurchases will be carried out in batches over time, not longer than up to
the next annual general meeting. The execution of the repurchases will depend on
market conditions and the repurchases are to be made in accordance with
applicable rules. Among other things, the number of shares repurchased on any
given day, with the exception for any block transactions, cannot amount to more
than 25 percent of the average daily volume during the four calendar weeks
immediately preceding the week during which shares are repurchased. Repurchases
may only be made at a price per share within the price range applicable, i.e.
the range between the highest purchase price and the lowest selling price. In
line with the purposes set out in the authorisation given by the annual general
meeting, the repurchases are made to flexibly and suitably distribute capital to
the shareholders and promote a more appropriate capital structure in light of
the current financial position of Medivir. Repurchases may be made of a maximum
number of shares corresponding to one tenth of the total number of shares in the
company, i.e. a maximum of 2,696,603 shares. As of today, Medivir holds no own
shares (treasury shares).
