Potential for development

The market environment is positive: the trend towards ‘smart’ and energy-efficient buildings ensures continued growth while expanding the market especially for electrical building services, which is predominantly what R+S offers. The company’s realignment, which is already well underway, is expected to be completed over the next few years, thus enabling further strong revenue growth. Further acquisitions will also contribute to this. DBAG is strengthening the company’s equity position, thus accelerating the successful realignment of the company.
