Markets and market position

Sales by markets

Products from Pfeiffer Vacuum are employed in numerous industry markets. Over 14,000 customers trust in the reliability of our products. Pfeiffer Vacuum divides these customers into the following markets: semiconductor, industry, coating, analytics, and research & development.

As far as the positioning of these markets is concerned, only a limited amount of data is available regarding the size of the entire market and individual market segments. Based on surveys conducted by the German Engineering Federation (VDMA) as well as our own estimates, we expect to take the leading market position in the market segments of industry, coating, analytics, and research & development. In the semiconductor market segment, we should rank second.

Without vacuum technology, a number of innovative processes would be inconceivable, such as in nanotechnology, in producing LEDs or in scientific research. Many of these new technologies create innovative products and production processes. Strong advances in people’s personal and professional communication patterns, for example, are bringing forth ever more new technologies in the semiconductor industry. The rising demand for energy coupled with the need to conserve resources is leading to a steadily increasing amount of new developments in the field of energy supply. These, and further social and industrial trends, are typically producing additional marketing opportunities for Pfeiffer Vacuum. Our strengths include the ability to serve all markets, which makes us largely independent of developments in individual market segments.

Pfeiffer Vacuum Market Segments


Our vacuum pumps are required in the semiconductor industry for the production of microprocessors and handling systems. Customers in this industry predominantly require a large number of medium-sized and large backing pumps, but also turbopumps, as well as measurement equipment. Chip manufacturers can significantly increase their yield with our decontamination systems. The semiconductor industry itself particularly benefits from the changes in communication technology. New fields of application for vacuum arise, for example, in nanotechnology. Our customers are increasingly located in Asia, and also in the United States, as well as – to a lesser extent – in Europe.


In this segment, we combine a heterogeneous category of industrial customers who require our vacuum solutions for specific production steps. Industrial trends such as quality improvement, energy supply, and conservation, mobility or environmental protection are currently leading to new fields of application. Examples include metallurgy, tube production, as well as air conditioning and refrigeration technology. A further field of application is solar thermal energy. The absorber tubes needed for this technology are evacuated by using our pumping stations as well as continuously being tested for leaks with our leak detectors. Our customers in the industrial segment primarily come from Europe, as well as from the United States, and increasingly from Asia.


Our largest customers in this market are so-called OEM (Original Equipment Manufacturer) customers, i.e. manufacturers of industrial systems or analytical instruments. Complex analytical devices such as scanning electron microscopes are primarily employed for industrial quality control. This industry is characterized in particular by megatrends such as Life Science, Biotechnology, and Security. Ever smaller and lighter portable analyzers are required in environmental technology, in security technology or for doping analyses. The analytical industry therefore typically requires small and medium-sized turbopumps along with backing pumps and measurement equipment. Our major customers in this market are located in the United States, Japan, the United Kingdom, and Germany.

Research & Development

Collaboration with research facilities enjoys a long tradition at Pfeiffer Vacuum. Whether in physics or chemistry laboratories at universities, prominent research institutions like the Fraunhofer and Max Planck Institutes or in large multinational research facilities – all of them rely upon the quality and dependability of our mass spectrometers, leak detectors, or vacuum solutions. Working in close cooperation with research facilities in Europe, the United States, and Asia, new applications arise continuously in the fields of energy supply or healthcare technology.


Without vacuum, many things that are used in daily life could not be produced in the desired quality. The antireflective coatings on eyeglass lenses, the coatings within flat screen manufacturing, the coatings on Blu-ray discs or on high-quality bathroom faucets and fittings as well as the coatings on solar cells or architectural glazing are produced in vacuum chambers, for example. High-quality tools are coated and hardened under vacuum to make them even more durable. One significant megatrend in this segment is the orientation towards regenerative energies, such as solar energy. What is predominantly required in the coating industry are medium-size and large backing pumps and turbopumps as well as measurement equipment and complete vacuum systems. Our customers are located in all industrial nations.

Strategy and control


Corporate Management

The Management Board of Pfeiffer Vacuum Technology AG assumes responsibility for the strategic leadership of the Corporate Group.

The Group companies were allocated to the business units “Semiconductor & Coating” or “Analytics & Industry” according to the focus of their operations and the market potential. They are directly subordinated to this business unit, and their comprehensive regional responsibility for all market segments continues to apply unchanged.

All subsidiaries in the Group therefore have self-directed managements and essentially make their own decisions within central guidelines on how to attain the targets that have been defined by Corporate Headquarters and the business unit (sales, EBIT margin and earnings before taxes). The supervisory bodies of the subsidiaries, whose composition also includes members of the Management Board of Pfeiffer Vacuum Technology AG, the heads of the business units or Headquarters in Asslar, Germany, must be involved in the case of major decisions.

Steering instruments

All subsidiaries are steered by Corporate Headquarters in Asslar through the stipulation of annual sales and profitability targets (“Management by Objectives”), and thus primary steering lies with the legal entities in the regions.

The achievement of these targets is monitored by means of detailed target/actual comparisons and variance analyses within the framework of monthly reporting, which was expanded to market information, to additionally take account of the requirements of the business unit structure. This ensures that undesirable trends will be identified and corrected early on. Monthly conference calls with the management of the subsidiaries additionally ensure that all business development questions are discussed. In addition, face-to-face meetings with staff at the local site are held by Group and business unit management. For countries in which Pfeiffer Vacuum is not represented directly through a subsidiary, the sales targets are agreed with the local distribution partner. Here, too, the achievement of sales targets is measured by means of target/actual comparisons. A further steering instrument consists of the variable remuneration of the local management of the non-German subsidiaries and of the sales staff. This sensitizes employees to cost structures, and so to the Company’s long-term success, even if they do not work in areas of the Company which have a direct influence on sales.

Risk and Opportunities Report

In order to achieve sustained success and remain competitive, Pfeiffer Vacuum always strives to recognize early on and actively utilize opportunities that present themselves. Seizing opportunities often involves consciously taking risks but handling these responsibly. Overall, we strive to achieve a balanced relationship between opportunities and risks by facing and countering them systematically and in a controlled manner, while avoiding risks that could jeopardize the company’s existence.

Risk and Opportunity Management System

We define risks as possible future internal or external events or fluctuations that could have a negative impact on the achievement of our corporate objectives or result in deviation from the planned figures in the underlying corporate planning. Accordingly, we define opportunities as potential events or developments that could contribute to the achievement of our corporate goals.

Overall responsibility for Pfeiffer Vacuum’s effective risk and opportunity management system is borne by the Management Board. Identifying and exploiting opportunities is essential to ensure the continuous success of the Company. These opportunities are continuously evaluated by management, taken into account in the planning processes and implemented in the business process. The risk management system is being continuously developed and adapted to the latest internal and external requirements in close coordination between the Management Board and the Global Compliance & Risk Management department.

The principles, procedures, roles and responsibilities as well as the requirements for reporting risks and countermeasures within the Group are set out in the Group Policy: Risk Management.

Tax Reporting

In recent years, the issue of taxing internationally active corporations in countries in which their companies are domiciled has increasingly come to the forefront of public debate. The attached report outlines Pfeiffer Vacuum’s approach.
