Advanced Pressure Technology California Layoffs 2025: What Employees Should Know

What the filing says

These are the details as Advanced Pressure Technologyreported them to the state. The EDD publishes every notice, and these figures come from the state's report as retrieved on Aug 13, 2026.

How much notice the law requires

California's WARN Act requires 60 days of advance written notice before a covered mass layoff, and its only statutory exception is a physical calamity or an act of war — far narrower than federal law's three. Who is covered and how the thresholds are counted is in our California WARN Act guide.

Advanced Pressure Technology severance: what to check before you sign

A severance offer is not the notice pay the WARN Act describes. Severance you were already promised — in a contract, a handbook, or a union agreement — cannot be used to satisfy that obligation, though Labor Code section 1402 does let an employer reduce a back-pay award by voluntary payments it was never required to make. A release may also give up more than you expect. Justin reviews severance agreements before workers sign. What to check before you decide is in our full guide to the California WARN Act.

Two things worth doing this week either way. File for unemployment now — WARN money does not reduce it, and the filings here run through Dec 1, 2025, so you do not have to wait for your last day. And keep every document, including the notice itself and anything showing when it arrived.

Questions people are asking

Where a layoff can raise a legal question

A layoff is lawful on its own, and nothing below is a statement about Advanced Pressure Technology. These are the places California law can still come into play, depending on the facts of your own situation.

• The severance you were asked to signA release can give up claims you did not know you had, and the terms are sometimes negotiable.
• How you were selectedA reduction in force still cannot be used to cut someone for a protected reason such as age, disability, pregnancy, or a complaint they made.
• Your final paycheckCalifornia sets when final wages are due at termination, and unpaid time or accrued vacation can carry penalties on top of the wages.

General information about California law, not legal advice, and reading it does not create an attorney-client relationship.

What has been reported

Press coverage of this layoff, summarized and attributed. This is reporting rather than the filing itself, and we did not independently verify it.

Advanced Pressure Technology, known as AP Tech, is closing its Napa plant and laying off all 237 remaining employees, the North Bay Business Journal reported. The company, founded in San Rafael in 1987, moved into its 77,000-square-foot Napa facility in 1997 and was acquired by Japan-based SMC Corporation in 2007. It makes pressure regulators and valves for the semiconductor industry.

The Napa Valley Register reported that the work will be consolidated at SMC Corp. of America's headquarters in Noblesville, Indiana, with the company saying "the cost of maintaining the facility in California has remained higher than can be supported." SMC Corp. of America president Kelley Stacy said: "This was not an easy decision. The Napa team has demonstrated exceptional skill, dedication and care for our customers."

The North Bay Business Journal reported that the company pointed to international trade disputes and falling customer demand, with its HR manager writing that "our proactive efforts to preserve jobs have not been enough" and that "workload has continued to decline and show no sign of recovery." The closure follows an earlier 2025 round of layoffs at the same plant.

A PAGA case is not a class action, and there is nothing to opt out of. A PAGA settlement resolves civil penalties owed to the state — most of which the state keeps — and it does not necessarily resolve your own unpaid wages, missed break premiums, or final-paycheck penalties. If you worked here and were not paid correctly, that is a separate question worth asking about. How California wage claims work.
