Overview
Aargau is Switzerland's industrial heartland, a powerhouse canton with a GDP of CHF 42 billion and a population of approximately 700,000. Strategically positioned at the geographic crossroads of the country -- between Zurich, Basel, and Bern -- the canton benefits from unmatched transport connectivity and serves as a critical link in Switzerland's economic infrastructure. The cantonal capital Aarau, together with the industrial cities of Baden, Wettingen, Brugg, and Lenzburg, forms a corridor of manufacturing excellence and technological innovation.
The canton's industrial heritage runs deep. ABB, one of the world's largest industrial technology companies, has its roots in Baden, and the city continues to host major GE energy technology operations. This industrial DNA permeates the canton, which is home to thousands of manufacturing, precision engineering, and supply chain companies serving the pharma clusters of Basel and the technology ecosystem of Zurich. Aargau is also Switzerland's most important energy canton, hosting three nuclear power plants (Beznau I & II, Leibstadt) and the Paul Scherrer Institute (PSI), the country's largest research facility.
The pharma supply chain sector is a particular strength, with contract manufacturing, packaging, logistics, and specialized component suppliers clustered throughout the canton. This creates a dense web of interdependent businesses that drives M&A activity as multinationals continuously optimize their supplier networks. The IT and technology sector is growing rapidly, fueled by the Innovaare technology park adjacent to PSI and the FHNW university system.
With 48,000 companies -- 98.8% of which are SMEs -- Aargau has one of Switzerland's largest business populations. The net formation rate of 2.3% indicates healthy entrepreneurial activity. However, the succession challenge is equally large in scale: an estimated 5,800 companies face ownership transitions in the coming decade, representing one of the largest pools of M&A opportunity in the country. The canton's position between three major economic regions means both strong competition for talent and exceptional access to capital, advisory services, and potential acquirers.
