Structurally rising electricity demand driven by AI and electrification, with a revenue base split across roughly 41% utilities, 48% state and local governments, commercial segment tied to data centers. FY2025 marked a breakout year with net revenue up 23%, adjusted EBITDA up 40%, and adjusted EPS up 101%, while margins expanded to 21.8%, exceeding its long-term 20% target.
Q4 2025 reinforced this momentum with revenue of $173.7 million versus $144.1 million YoY and adjusted EPS of $1.57 versus $0.75, highlighting strong operating leverage. Investment case centers on Willdan’s repositioning from a traditional efficiency consultant to a grid capacity and load growth solutions provider, particularly APG acquisition and expanding data center backlog extending into 2027–2028. Management has signaled robust acquisition pipeline that can further accelerate scale and margin expansion.
Despite near-term EPS optics impacted by assumed 179D normalization, underlying EBITDA strength and cash generation remain intact, supported by $71 million in free cash flow and a net cash balance. Retail-like mispricing stems from investors underappreciating the durability of data center driven demand, contract conversion visibility, and structural margin uplift.
With continued commercial expansion, sustained >20% margins, and accelerating backlog conversion, Willdan is well positioned for a re-rating as market recognizes its exposure to one of the most important infrastructure buildouts of the decade as downside remains limited by cash flow visibility disciplined execution clearly.
