Investment thesis
Sterling Investment Partners positions itself as a go-to middle-market private equity firm concentrating on distribution and business services. It targets recession-resistant segments characterized by secular growth tailwinds, significant fragmentation, and recurring demand dynamics. The firm favors businesses with recurring demand, competitive advantages from scale, technology leadership, and those that compete on a basis other than price, across after-market and MRO parts, building and facilities services, consumables, and essential outsourced services. Sterling takes a patient, long-term, customized approach to each investment, viewing management teams as true partners and working collaboratively to grow companies with GDP-plus growth end markets and strong free cash flow generation.
