Willdan's stock plummeted 16.26% during intraday trading on Friday, reflecting a sharp decline in investor confidence.
The drop follows the company's release of its financial outlook, which set 2026 adjusted diluted EPS guidance at USD 4.50 to USD 4.70, below the USD 4.89 achieved in 2025. This forecast disappointed the market, even as Willdan reported strong fourth-quarter and full-year 2025 results, including a 143.4% surge in Q4 net income to USD 18.7 million.
The weaker-than-expected earnings projection for the coming year appears to have driven the significant sell-off, overshadowing the recent positive performance.
