Willdan Group (WLDN) Stock Forecast & Price Target

Willdan Group is positioned for stronger growth because the $285 million Mantis acquisition expands its energy efficiency, advisory, and facility asset management reach into attractive commercial end markets like data centers, food and beverage, and healthcare, while adding a 2026 revenue base of $120 million at a low-20s adjusted EBITDA margin. The deal should improve mix and synergies across Burton, APG, and Mantis, potentially adding up to $20 million of net revenue and supporting earnings accretion in 2027, even as the valuation is offset by strategic fit and cross-selling potential. In parallel, the KCS acquisition strengthens APG’s capacity-constrained power engineering bench, broadens Midwest exposure, and should help convert a pipeline of data center, battery storage, and grid modernization projects more quickly.

Willdan Group is facing integration and concentration risk from the Mantis acquisition, as data centers account for more than 30% of Mantis’s revenue and could rise to the mid-teens as a share of pro forma WLDN, increasing exposure to a cyclical end market. The deal also appears margin dilutive because Mantis carries a lower Adj. EBITDA margin than Willdan’s ~25% FY26 guidance, potentially creating about 50 bps of pro forma dilution and offsetting roughly one year of management’s targeted 50 to 100 bps annual expansion. While the acquisition expands Willdan’s footprint in building controls and utility demand-response opportunities, the weaker profitability and execution risk around integration temper the fundamental outlook.
