Asslar, Germany (ots - Ad hoc-Service) - Pfeiffer Vacuum increased Net Sales and Profits significantly, despite Asia's economic crisis

The hightech company, a
manufacturer and global vendor of vacuum pumps and components, didn't suffer significantly from the Asia crisis and the problems of the semiconductor industry, due to its well balanced geographical sales and limited exposure to the semiconductor industry.

Pfeiffer could increase its net sales in the 6 month period ended June 30, 1998 by nearly 7 % compared to the year before. Of even greater significance was the increase in net income by 78 % up to 11.5 million DEM as compared to the 6 month period ended June 30, 1997.

Besides the net sales both order intake and backlog increased by 22 %. These increases do not include a one-time order of 15 million Deutsche Mark for a solar cell production line.

Key numbers of the 6 month period ended 30 June 1998:

Net Sales 141.5 million DEM + 7 % Net Income 11.5 million DEM + 78 % Earnings per ADS 1.76 DEM + 7: Paragraph 15 WpHG-Mitteilung ------------------------------------------------------------------- Im Internet recherchierbar:
