What SigmaTron International does

SigmaTron International, Inc. is a mid-tier Electronics Manufacturing Services (EMS) provider founded in 1993 and headquartered in Elk Grove Village, Illinois. The company delivers contract manufacturing of printed circuit board assemblies (PCBA), cable harnesses, system integration, and box build services to enterprise customers across five verticals: Industrial, Consumer, Medical/Life Sciences, Aerospace/Defense/Security, and Automotive. Operations span 7 manufacturing facilities totaling over 830,000 sf across the United States, Mexico, China, and Vietnam, with a Taiwan International Purchasing Office providing centralized sourcing. The company employs 2,800+ people and serves 168+ active customers, historically generating approximately $391 million in annual net sales.

The company's core offering is organized under its "One Source, Global Options" framework, combining PCBA manufacturing, new product introduction (NPI), supply chain management, system integration, product development support, and post-manufacturing solutions. Differentiated capability is anchored in proprietary IT infrastructure: the SCORE™ customer portal providing 24/7 real-time ERP visibility, the iScore suite of supply chain management tools supporting vendor-managed inventory and Production Driven Replenishment (PDR), and an internally-developed Manufacturing Execution System (MES) supporting serialization, traceability, automated CAPA reporting, and device history recordkeeping. The company holds ISO 9001:2015, ISO 13485:2016, IATF 16949, AS9100D, FDA device licensure, and ITAR registrations across multiple sites, providing entry credentials into regulated end-markets.

SigmaTron was publicly traded on NASDAQ (SGMA) until it was acquired by Transom Capital Group in July 2025 for approximately $83 million, becoming a privately held company. Revenue runs through direct field sales targeting enterprise OEMs on a custom-quoted contract basis; pricing is not publicly disclosed. The company is currently navigating a downturn, with Q3 FY2025 net sales of $71.1 million down 25.9% year-over-year and a nine-month net loss of $8.9 million, while a new CEO (Jim Kircher) and refreshed executive team have been installed to drive operational restructuring and growth under private ownership.
