The San Mateo County contract electronics manufacturer filed a California WARN notice July 7, citing "changing business needs" — nothing more. The closure includes the company president and reaches the top of the org chart.

LeeMAH Electronics filed a WARN Act notice with California state officials on July 7, disclosing it will close its headquarters at 155 South Hill Dr. in Brisbane and lay off all 212 workers there beginning September 8. The company's stated rationale in the letter to state officials: "changing business needs."

The closure reaches the top of the org chart. The 212 affected positions include the company president, 11 group leaders, 8 managers, 6 supervisors, and 92 assemblers — with roughly 84 additional roles not broken out in available records — per Hoodline's reporting on the WARN filing. Because 155 South Hill is LeeMAH's listed headquarters, not a branch location, this is a full wind-down.

At 212 workers, the LeeMAH notice is the largest active filing in California's current WARN window; Chevron's 180-person San Ramon reduction is next, per the independent tracker californiawarn.com.

LeeMAH has issued no public statement beyond the WARN notice. No union representation for the affected workers has been confirmed, and no workforce development agency has announced a rapid-response effort. What drove the closure — a lost contract, a financing shortfall, or a managed exit — remains undisclosed.
