Vestum's process



We strive to engage in continuous discussions with interesting acquisition candidates, both directly and through advisers. In total, we evaluate more than 100 companies each year.



Vestum evaluates potential acquisitions based on a number of parameters to create a deeper understanding of the company’s business model, risks, market position, competitive landscape, financial history and prospects, as well as the continued commitment of key personnel. During the evaluation process, Vestum formulates a value-creation hypothesis for how we can help drive profitable growth.



During the implementation phase, Vestum conducts a commercial, legal and financial screening of the target company, followed by negotiations and signing of the agreement.



After the acquisition has been completed, a plan is developed for how the business can best be incorporated into the Group to maximize the benefits of being part of Vestum. In addition to working together on strategic issues that arise, the acquired company's management maintains a continuous dialogue with the Group management. The focus of day-to-day management is on growth, profitability and working capital.
