(GIC), bringing the two parties’ respective stakes to 17% and 14% of the total share capital of Straumann Holding AG.

My belief in the long-term future of Straumann is undiminished, and I have every confidence in its business fundamentals, people, and strategy. Straumann remains my core investment, and I fully intend to continue contributing to its direction as a principal shareholder for the long-term.”

In addition, Dr Straumann has agreed to a one-year lock-up period, during which he will not reduce his stake.
