Ad hoc announcement acc. to Sec. 15 WpHG : United Internet decides to buy back further treasury shares

Montabaur, May 27, 2011. The Management Board of United Internet AG (ISIN DE0005089031) today resolved to launch a new share buyback program. In the course of this new share buyback program, up to 7,500,000 company shares (corresponding to approx. 3.33% of capital stock) are to be bought back via the stock exchange. The resolution follows the authorization of the Annual Shareholders' Meeting of May 26, 2011 to buy back and sell treasury shares representing up to 10% of the company's capital stock. The authorization was issued for the period up to November 26, 2012.

The Annual Shareholders' Meeting of May 26, 2011 revoked the former authorization of June 2, 2010 to acquire and sell treasury shares on expiry of May 26, 2011 with effect in future. The last share buyback program adopted on the basis of this authorization on April 11, 2011, during which 1,500,000 treasury shares were to be repurchased, will thus no longer be continued.

United Internet AG currently holds 15,000,000 treasury shares, corresponding to around 6.67% of capital stock.

Treasury shares can be used for all purposes stated in the authorization of the Annual Shareholders' Meeting of May 26, 2011, in particular for current and future employee stock ownership plans and / or as an acquisition currency. However, they may also be cancelled without any further resolution of the Annual Shareholders' Meeting.
