Bad Ragaz/Switzerland, April 20, 2011.

Significant Sales Increase
INFICON Holding AG (SIX Swiss Exchange: IFCN) reported for the first quarter 2011 a sales increase of 36.1% (foreign currency exchange effects of 5.0 percentage points and 2.3 percentage points acquisitions) to USD 81.8 million, which represents a new all-time high. The good business performance was made possible by the continued positive market developments, selective internal capacity increases as well as the elimination of bottlenecks on the procurement side. This enabled to reduce the backlog and in turn improve delivery times.

Markets for Semiconductors and Refrigeration & Air Conditioning with Strongest Increases
The most notable delivery increases were recorded in the market for Specific Vacuum Process Industries (+71% to USD 32.3 million) to the manufacturers of memory and microprocessor chips, but also to display and OLED manufacturers. The strongest demand in this target market continued to come from Asia, followed by Europe. The market for General Vacuum Processes reported an increase of +30.5% to USD 33.9 million. Significantly driven by Asian demand, sales increased in the market for Refrigeration & Air Conditioning by +45.3% to USD 12.5 million. Not least as a result of the uncertain federal budget situation in the US, the expected orders from government agencies in the Emergency Response & Security market did not occur. Consequently INFICON’s smallest market was down substantially over last year (-52.9% to USD 3.2 million).

Income From Operations Doubled
INFICON generated in the first quarter of 2011 income from operations of USD 15.8 million, which corresponds to a margin of 19.3 percentage points and a doubling over the prior-year period (+106.5%). The first quarter recorded a solid operating cash flow of USD 8.9 million after re-cording USD 12.0 million in the prior-year period. The inventory turns and days sales outstanding have been actively addressed so that net working capital remained stably below 20%, and INFICON closed the year with cash and cash equivalents of USD 79.5 million. The balance sheet continues to remain strong with an equity ratio of 74.3%.

Compared to the first quarter of 2010, net income for the period was increased by +88.0% to USD 10.8 million. This amounts to earnings per diluted share of USD 4.89 compared with earnings per diluted share of USD 2.65 last year.

Outlook
Given the now mostly normalized procurement and production situation, and based on the assumption that the impacts of the catastrophe in Japan will not have massive negative effects, INFICON has raised its sales target and expects for the full year 2011 sales in the range of USD 270-310 million and significantly higher income from operations of USD 42-54 million.
