LeeMAH Electronics' Brisbane Closures: 205 Workers This Week, 62 More in December

A manufacturer in Brisbane, California is winding down in two stages, according to WARN filings tracked by Layoff Atlas. LeeMAH Electronics filed a permanent closure notice affecting 205 workers with a planned effective date of October 16, 2026, and a second closure notice for 62 more workers at the same address, effective December 21, 2026. Together, the two filings cover 267 reported workers at a single site: 155 South Hill Drive in Brisbane, San Mateo County.

What the filings say

The larger filing was noticed on August 17, 2026, with the effective date set for October 16 - a full 60 days later, in line with the federal WARN Act's standard notice window. The source agency is the California Employment Development Department, and the record classifies the event as a permanent closure in the manufacturing sector.

The second filing, for 62 workers, carries a notice date of September 11, 2026 and an effective date of December 21, 2026 - again roughly the 60-day pattern. It names the same company and the same Brisbane address.

One important note: these are reported plans, not confirmed job losses. WARN filings describe what an employer has announced; they do not confirm that every listed worker was ultimately separated. Treat the figures as a forward-looking signal, not a final count.

Why two filings for one address

It is common for a single facility closure to show up as more than one WARN record. Employers may file separately for different waves of separations, or file an initial notice and then a follow-up as plans firm up. In LeeMAH's case, the two notices are a little under a month apart and point to the same location, which reads as a staged wind-down: the bulk of the workforce this week, with a smaller group effective in December.

Where this filing sits in the national picture

As of the October 14, 2026 data sync, Layoff Atlas is tracking 711 notices covering 65,795 reported workers. California is the second-hardest-hit state on the tracker, with 15,138 reported workers, trailing only Washington at 16,722. The October 15 effective week carries 3,513 reported workers in total, and the weeks of October 29 and November 19 are heavier still, at 8,646 and 8,275 reported workers respectively.

What workers at an affected site should know

If you work somewhere that just appeared in a WARN filing, the notice itself gives you a baseline of rights. Federal law generally requires 60 days of advance written notice of a plant closing or mass layoff at employers with 100 or more full-time workers, and California's Cal-WARN law extends similar protections with broader coverage. Workers affected by a filed notice typically become eligible for unemployment insurance, and those losing employer-sponsored health coverage may be eligible for continued coverage under COBRA.

The bottom line

LeeMAH Electronics' two filings total 267 reported workers at one Brisbane manufacturing site, with the main wave effective October 16, 2026 and a final 62-worker group effective December 21.
