News Release

February 28, 2007

Merck KGaA Holds Nearly All Voting Rights in Merck Serono S.A.

 

Geneva, Switzerland, February 28, 2007 — Merck Serono S.A. (virt-x: SEO and NYSE: SRA) has been informed by Merck KGaA of the preliminary final result of the public tender offer for all publicly held bearer shares of Merck Serono S.A. (formerly Serono S.A.). Following the expiration of the offer period on February 22 and including those shares purchased on the market, Merck holds a total of 11,013,040 registered shares of Merck Serono with a par value of CHF 10 each and 10,923,150 of Merck Serono’s bearer shares with a par value of CHF 25 each.

This corresponds to 100.4% of the voting rights of Merck Serono entered in the Swiss Commercial Register as well as an interest of 100.6% in the share capital entered in the Swiss Commercial Register. The amount of more than 100% is a mathematical result since the calculation was based on the share capital entered in the Commercial Register as of the balance sheet date. Merck Serono’s share capital has meanwhile increased due to the exercise of options. Merck currently holds 99.1% of actually issued voting rights as well as 98.7% of actually issued share capital.

After reaching the necessary threshold of 98%, Merck KGaA announced that it intends to conduct a squeeze-out for the remaining outstanding shares in order to acquire a 100% interest in Merck Serono’s actual share capital. In addition, Merck KGaA has also announced that it intends to delist the Merck Serono shares in Switzerland as well as to deregister the Merck Serono Shares under the U.S. Securities Exchange Act of 1934 and delist such shares, in form of American Depository Shares, from the New York Stock Exchange.
