About Willdan Group, Inc.

Willdan Group, Inc. (NASDAQ: WLDN) is a U.S.-listed professional services and consulting company headquartered in Anaheim, California, United States. Founded in 1964, the business originally served public agencies and has since expanded into energy efficiency, decarbonization, infrastructure modernization, and technical consulting. For investors, Willdan is best viewed as a specialized energy-and-infrastructure services platform rather than a broad-based engineering conglomerate.

Its service mix includes engineering, program management, policy advisory, software, and data-management capabilities.

The company states that it serves a majority of the largest investor-owned electric utilities and more than half of the largest municipal utilities in the United States. Its footprint is nationwide, with offices across 22 states, the District of Columbia, Puerto Rico, and Canada, while its public-agency business is concentrated in California, New York, and Arizona.

In November 2025, Willdan announced a $97 million contract with Alameda County to design and implement energy and infrastructure upgrades, including HVAC electrification, solar PV, EV charging, and other decarbonization and maintenance improvements. The company also released its 2024 Sustainability Report, underscoring the strategic importance of ESG-linked services and its positioning in the energy-transition market. Recent company news has also highlighted additional contract wins and acquisitions intended to expand its commercial energy capabilities.
