Mergers have become a common topic of discussion among nonprofit leaders, boards, and funders. They are often seen as a way to preserve and strengthen needed community services. However, organizations have been challenged by the lack of research based information about what factors influence the outcomes of a merger. This study was done to add to the body of knowledge about why direct service nonprofits decide to merge, how the process is completed, what happens following a merger, and what factors most influence merger outcomes. The resulting information is intended to help guide nonprofit leaders, staff, funders, board members, and other stakeholders to make decisions and assess the potential for success in nonprofit mergers.
