What these concentrations mean together
updated 2026-07-06Willdan's concentration risk centers on customer dependency at a high-share level, with geography and a narrower customer subset both sitting at medium-share. The top 10 customers accounted for 50.7% of consolidated contract revenues — a high-share dependency on a relatively small set of named relationships. Geographically, California contributed 43.5% of consolidated contract revenue in fiscal 2025, with New York at 19.0% and Nevada at 11.8% — a medium-share structural exposure to a handful of states rather than to any single counterparty. Within the Energy segment specifically, two customers — Clark County School District and Southern California Edison — together accounted for 27.4% of segment contract revenues, a medium-share dependency layered on top of the broader top-10 figure. These three exposures don't cleanly offset one another: the high-share top-10 customer concentration is the single figure most likely to move the verdict, since it describes over half of all revenue sitting with ten relationships, while the state-level and segment-level concentrations describe narrower slices of the same underlying business. Overall, Willdan's risk profile is dependency-heavy rather than purely structural, with real counterparty concentration layered on top of geographic concentration.
