Primech Holdings is a Singapore-based facilities services company that provides cleaning and maintenance services to commercial, public sector, and institutional customers. Its core business covers cleaning and maintenance of airports, public housing common areas, schools, hospitals, hotels, offices, and industrial facilities. Key customers include Singapore Changi Airport, the Singapore Ministry of Education, and the National Environment Agency, typically under multi-year contracts of two to four years, giving Primech a recurring revenue base. Primech wins business primarily through competitive tenders on government procurement platforms and direct solicitation of private sector clients. The business is organized into facilities services (~79% of revenue), office cleaning (~10%), and stewarding services — kitchen cleaning and F&B staffing in healthcare and hospitality venues (~11%). Primech employs roughly 2,800 people and keeps most service delivery in-house, with labor as its dominant cost. Contracts are priced either on an input basis (agreed staffing at cost-plus-margin) or output basis (fixed fee for a performance standard). Margin discipline depends on accurate cost estimation at the bidding stage and efficient workforce deployment. Primech is investing in autonomous cleaning robots and IoT-based management tools to improve worker productivity. The company is also expanding into landscaping, hospitals, and data centers, and has pursued bolt-on acquisitions to add customer bases and sector expertise.
