SUSS MicroTec AG: Divestment of SUSS MicroTec Precision Photomask Inc.

SUSS MicroTec AG: Divestment of SUSS MicroTec Precision Photomask Inc.

Garching, October 17, 2011 – The SUSS MicroTec AG has sold its mask manufacturing business - SUSS MicroTec Precision Photomask Inc. (formerly known as Image Technology Inc.) - in Palo Alto, California, on October 14, 2011 to Compugraphics Inc.. This move supports the expansion of the SUSS MicroTec Photo Mask Equipment business by eliminating competitive overlap with prospective customers. Synergies with the core equipment business were limited so that a deconsolidation will be possible easily. The divestment of the mask business is a further step of SUSS MicroTec to focus on its profitable and high growth core business areas. The transaction will have no effect on the consolidated income statement.

Compugraphics Inc., a wholly owned subsidiary of OM Group, has acquired all the assets of SUSS MicroTec Precision Photomask Inc. and will continue operations in the US. Compugraphics is a globally acting mask manufacturer with mask shops in the US, UK and Germany.
