Willdan's Margin Expansion Story: Too Hot to Cool Anytime Soon?
Read MoreHide Full Article
Key Takeaways
Willdan's adjusted EBITDA margin expanded 360 bps to 21.6%, driven by execution discipline and mix.
The Energy segment exposure supports recurring revenues and structurally higher margins for Willdan.
Acquisitions and data center demand reinforce margin expansion visibility ahead for WLDN.
Willdan Group, Inc. (WLDN - Free Report) continues to build a compelling narrative of margin expansion, and recent results suggest the story may be far from peaking. During the first nine months of fiscal 2025, it delivered robust profitability, driven by strong execution, a favorable product mix and disciplined cost control. Adjusted EBITDA during the said time frame increased year over year by 52.4% to $59.5 million, with adjusted EBITDA margin expanding 360 basis points (bps) to 21.6%.
The primary driver behind the margin momentum is the company’s growing exposure to higher-value energy and infrastructure services. Willdan’s Energy segment, which accounts for roughly 85% of revenues, benefits from long-term utility contracts, recurring program management work and rising demand tied to data center-driven electricity load growth. These engagements typically offer better pricing visibility and execution leverage, supporting steady margin improvement even as the company continues to invest in growth.
Notably, during the first nine months of fiscal 2025, gross profit increased 30.6% year over year, with gross margin expanding 290 bps. This uptrend was backed by improved project delivery efficiencies and scale benefits offsetting inflationary pressures.
Strategic acquisitions, including APG, are further enhancing Willdan’s margin profile by expanding its presence in power engineering and data center infrastructure, areas with attractive economics and long-term demand visibility. With a strong pipeline, rising backlog and exposure to one of the largest infrastructure investment cycles in decades, WLDN’s margin expansion story appears well supported, making it unlikely to cool anytime soon.
Willdan’s Competition Position
Willdan operates as a specialized engineering, energy efficiency and consulting firm focused on utility programs, grid modernization and sustainability services. Given the business areas, it faces substantial competition from renowned names like AECOM (ACM - Free Report) and Tetra Tech, Inc. (TTEK - Free Report) .
AECOM is a large, diversified global infrastructure consulting and engineering company offering urban planning, construction and program management across transportation, energy and environmental services sectors. With a broad service spectrum, AECOM competes for large-scale infrastructure and consulting contracts where scale and multi-disciplinary capabilities are decisive. On the other hand, Tetra Tech is a global professional services firm concentrated on water, environment and sustainable infrastructure, delivering consulting, engineering and program management solutions. Its science-led approach and strong presence in environmental and resilience projects differentiate it within those segments.
Compared with its peers, Willdan’s more focused energy-centric and utility program expertise allows it to target niche electrification and efficiency markets. On the other hand, AECOM and Tetra Tech leverage broader service portfolios and international scale to compete across wider infrastructure and environmental markets.
