Company Information

Heico has a history of success. Since its founding over 40 years ago, The Heico Companies has grown from a single business to over 78 separate companies through a strategic acquisition policy and by reinvesting its earnings into internal growth and new prospects. Historically talented at restoring distressed companies, Heico strategically targets acquisitions that complement its ever-growing portfolio of companies in manufacturing, construction, and industrial services.

These four core operations are organized into groups: Applied Solutions Group, Construction Solutions Group, Industrial Technologies Group, and Metal Processing Group. Once acquired, new Heico companies are assigned to a group and run on a stand-alone basis, allowing for great independence as well as the opportunity to share knowledge about markets, production processes, and management practices across other Heico groups and companies.

Heico continues to seek out new opportunities and maintain its standard of success. The Heico Companies has remained a privately held company since its creation and maintains a majority ownership in each of its operations, which generate more than $3.3 billion in annual revenues. Many of our businesses are certified Woman-Owned Business Enterprises (WBE).
