VAN DER MOOLEN HOLDING N.V. annonce l'acquisition de Robbins & Henderson et la vente de 123 646 actions NYSE

Van der Moolen Holding NV (VDM) annonce un accord de principe portant sur l'acquisition de 100 % du courtier institutionnel américain Robbins & Henderson LLC (R & H). R & H offre une large gamme de service de courtage grâce à son équipe expérimentée de professionnels de l'industrie. En 2006, le chiffre d'affaires brut s'élevait à 6,4 millions de dollars.

VDM doit encore obtenir l'autorisation réglementaire.

The acquisition price is based on the earnings of R&H for the years 2006, 2007 and 2008. For 2006 the price amounts $ 2 million. The acquisition price for 2007 and 2008 respectively will be the net profit for the year multiplied by factor 4.5 for 2007 and factor 4 for 2008. R&H will be included in the VDM figures as of third quarter 2007 earnings.

Richard den Drijver, CEO of VDM: "This acquisition marks the start of a brokerage division for VDM in the US. This will bring us closer to achieving our goal to become a Global Securities Firm in 3 time zones acting as a liquidity provider, a broker and an investor and developer of exchanges. With R&H we can now offer professional services to our broker clients in the US."

Tom Hearden, CEO of R & H: "Together, VDM and R & H will provide a suite of products and services that will enable our customers to be competitive in a global arena. Additionally, this will enhance our ability to recruit experienced investment professionals thereby accelerating the growth of this effort."
