Duke Capital Limited operates as a private equity firm primarily engaged in Management Buyouts (MBOs), buy-and-build strategies, mid-market investments, minority buyouts, restructuring endeavors, and royalty financing for small to medium-sized enterprises (SMEs). The firm explicitly avoids investing in early-stage ventures, businesses with inherently tight profit margins, and does not provide venture capital funding. While its investment scope spans all sectors, Duke Capital exhibits a distinct preference for companies in manufacturing, services, healthcare, and IT services.
