Willdan Group (NASDAQ:WLDN) executives reported the company ended fiscal 2025 with 'record financial performance' and entered 2026 with momentum driven primarily by energy-related work, expanding program activity at utilities, and growing demand from data center customers. The company posted 21% year-over-year growth in contract revenue to $682 million and a 23% increase in net revenue to $365 million, with adjusted EBITDA rising 40% to $79.5 million.

Why it matters

Willdan's strong 2025 results and positive outlook reflect broader trends in the energy and infrastructure sectors, including the return of electric load growth, accelerating demand from data centers, and increased focus on energy efficiency, grid modernization, and reliability. The company's performance highlights its ability to capitalize on these market dynamics through its diverse service offerings.

The details

Willdan reported solid margin expansion in 2025, with gross margin increasing to 37.5% from 35.8% a year earlier. This was attributed to growth and productivity gains in program management and consulting services, along with reduced direct delivery costs. The company also benefited from a significant tax benefit of $12.6 million, driven by energy efficiency incentives and a higher stock valuation. However, 2026 adjusted EPS guidance of $4.50 to $4.70 is below 2025's $4.89, primarily due to the assumed expiration of Section 179D tax credits and a shift in project mix.
