Exelixis, Inc. California Layoffs 2025: What Employees Should Know

Exelixis, Inc. has 2 layoff notices on file with California's Employment Development Department (EDD) under the state's Worker Adjustment and Retraining Notification (WARN) Act, covering 145 jobs in Alameda County. That is what the state has published since July 2025, not an all-time total. If you were one of them, here is what the filing says, how much notice the law asks for, and what to look at before you sign anything.

What the filing says

These are the details as Exelixis, Inc. reported them to the state. The EDD publishes every notice, and this page reflects the data as of Jul 31, 2026.

Location	County	Notice given	Jobs end	Workers	Type
Alameda	Alameda County	Aug 29, 2025	Aug 29, 2025	74	Layoff Permanent
Alameda	Alameda County	Aug 26, 2025	Oct 27, 2025	71	Layoff Permanent

How much notice the law requires

California's WARN Act requires 60 days of advance written notice before a covered mass layoff. What makes the California version unusual is how few ways out it gives an employer. The only statutory exception is a physical calamity or an act of war. Federal law has three exceptions, including one for unforeseeable business circumstances, and the California Legislature deliberately declined to copy them.

What this filing shows

The shortest gap in these filings is 0 calendar days between the notice date and the date the jobs end. That is less than the 60 days the statute describes.

This is a fact drawn from the public filing, not a conclusion that anyone broke the law. The date an employer records is not always the date workers were told, employers of different sizes are covered differently, and exceptions can apply. Whether it means anything in your case is exactly what a free consultation sorts out.

Exelixis severance: what to check before you sign

A severance offer is not the same thing as the notice pay the WARN Act describes, and an employer cannot use one to satisfy the other. A release may also give up more than you expect, and an arbitration agreement you signed at hire can affect where a dispute is heard. Read our full guide to the California WARN Act before you decide, and consider having the paperwork looked at.

Two things worth doing this week either way. File for unemployment now, because WARN money does not reduce it. And keep every document, including the notice itself and anything showing when it arrived.

Questions people are asking

What is the Exelixis severance package?

The WARN notice Exelixis filed with the state does not list severance terms, and we do not publish any employer's package. A WARN notice reports how many jobs end, where, and when. Severance is a separate contract offered at the employer's discretion. California law does not require it, and an employer cannot use contractual severance to satisfy what the WARN Act requires, so being offered a package does not by itself answer whether notice pay is also owed. If you have an offer in hand, the terms in front of you are the ones that matter, and they are worth reading closely before the deadline on them runs.

Am I owed severance from Exelixis, Inc.?

California law does not require severance on its own, and a severance offer is a separate thing from WARN pay. An employer cannot use contractual severance to satisfy its WARN obligation, so being offered a package does not answer whether notice pay is also owed.

Does taking the severance reduce what I could recover?

It depends on why the money is being paid. Severance the employer was already obligated to provide — under a contract, a policy, a benefit plan, or a union agreement — cannot be set against what the WARN Act requires. A payment that is genuinely voluntary and unconditional, one the employer had no legal obligation to make, can reduce that liability. Wages for work you actually performed during the notice period are not voluntary severance at all. Which category an offer falls into is a question about the document in front of you, not about the layoff, and it is one of the better reasons to have the paperwork read before the deadline on it runs.

Why do co-workers have different last days?

The filings here list 2 separate last days of work. Employers commonly stagger a reduction so some functions run longer than others. Your own notice period is measured against your date, not the earliest one in the filing, so two people at the same employer can be in genuinely different positions.

What if I did not get 60 days of notice?

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. That is far narrower than federal law, which has three exceptions. The shortest gap in these filings is 0 days, which is 60 short of 60. That is arithmetic on two published dates and not a finding that anyone broke the law: the recorded date is not always the date workers were told, and coverage depends on the employer's size and how many people were let go.

Can I still collect unemployment?

Yes. Under Labor Code section 1407, WARN-related payments are not treated as wages for unemployment purposes, so they cannot be used to deny or reduce your benefits in California. You do not have to wait for your last day — the filings here run through Oct 27, 2025 — and filing early is generally better than filing late.

Does taking a new job hurt my claim?

No. Wages you earn at a new job during the notice period do not reduce what a former employer may owe under WARN. You do not need to delay a job search to protect a claim.

How long do I have to act?

Generally three years. The federal WARN Act sets no limitations period of its own, so courts borrow the closest state deadline, which in California is the three-year period for a liability created by statute. The clock starts when you suffer an employment loss, not when the notice went out. Measured from the last day of work in these filings, Oct 27, 2025, three years runs to about Oct 27, 2028. If this was a layoff rather than an outright termination, the loss may not count until the layoff has lasted more than six months, which can start the clock later still. Treat all of it as an outer edge rather than a plan. Other claims arising from the same layoff run much shorter, and a severance offer usually carries its own deadline measured in days.

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.

Fierce Biotech reported the Alameda cuts were part of a reorganization eliminating about 130 positions company-wide as Exelixis winds down its King of Prussia, Pennsylvania site to focus operations at its Alameda headquarters; a spokesperson said the company had hired a significant number of employees, including many fully remote positions, during the pandemic and post-pandemic period.

According to the California WARN notice as reported by Fierce Biotech, 71 employees at the Alameda site were laid off along with 33 remote employees who report to California-based managers; those dismissed included four vice presidents, a clinical trial manager and several scientists.

Details worth knowing

Exelixis hopes to reopen many of the impacted positions in Alameda, a company spokesperson told Fierce Biotech, and BioSpace reported the company is looking at the possibility of relocating some eliminated Pennsylvania roles to its Alameda headquarters.

What the numbers show

The 145 affected positions are in Alameda.
They cover 2 separate addresses rather than a single site, so co-workers at different locations may have received different dates.
The jobs do not all end on the same day. The filings list 2 separate last days of work, running from August 29, 2025 to October 27, 2025.
The shortest gap between notice and last day here is 0 days, against a statewide median of 61 days across every notice on file.
By headcount it sits in the top 25% of the 593 employer layoffs tracked here.
The 145 workers leaving Exelixis, Inc. re-enter a job market where Alameda County unemployment stood at 4.4% in June 2026, below the 5.2% statewide rate (Bureau of Labor Statistics, not seasonally adjusted).
All 2 notices are dated within a single month, August 2025, which reads as one event reported site by site rather than a rolling reduction.

These are counts and comparisons drawn from the published filings, not findings about Exelixis.

About this data

Where it comes from. Every figure on this page is reproduced from the WARN report the California Employment Development Department publishes at edd.ca.gov (opens in a new tab), retrieved Jul 31, 2026. Employers file these notices with the state, and the state publishes them as a public record.

We make no representation that it is accurate or complete. We reproduce the state's file as published and do not independently verify it. Notices are amended and withdrawn, employers correct their own filings, layoffs are called off, and the published report can lag or contain errors. Nothing here is a substitute for the EDD's own record, and if the two disagree, the EDD's is the one that counts.

How employers are grouped. The EDD's report lists one row per notice and often names the same employer several ways — with a store or site number, a warehouse code, a per-location name, or a spelling variation. This tracker groups those filings under one employer so a company's notices appear on a single page; every underlying filing still appears as its own row in that page's table. The grouping is ours, not the EDD's, and it never combines differently named companies, even ones related through ownership.

Nothing here says an employer did anything wrong. Filing a WARN notice is what the law asks an employer to do, so appearing in this data reflects compliance with the notice requirement rather than a violation of it. Where we show the number of days between a notice and the last day of work, that is arithmetic on two published dates and not a legal conclusion. The date recorded in a filing is not necessarily the date employees were told, employers of different sizes carry different obligations, and statutory exceptions can apply. Whether any particular layoff complied with the law is a fact-specific question that this page does not answer.

This page is general information about California law, not legal advice, and reading it does not create an attorney-client relationship. It is not affiliated with, endorsed by, or sponsored by Exelixis, Inc., and any company names are used only to identify publicly filed notices.
