Reading the Amentum WARN Record
With 10 separate WARN Act filings in this dataset, Amentum has one of the more extensive recorded layoff-notice histories, covering 686 workers from Mar 13, 2020 through Mar 9, 2026, and even that likely understates the real total (why). By total workers affected, Amentum ranks #53 of 757 tracked employers in WA. Among the 8 other Other Services employers with recorded WARN filings, the median is 3,640 affected workers -- Amentum's 686 sits well below that group's typical scale. Filings span 4 states, most concentrated in WA (Other Services), so more than one state workforce agency and mini-WARN threshold applied depending on where each notice was filed.
Averaging 69 workers per notice, Amentum's filings fall into a pattern that suggests targeted team or department cuts that still crossed the WARN reporting threshold. With 10 separate recorded filings, this is not an isolated event, the cadence of notices points to recurring workforce adjustment tied to industry cycles, merger integration, or capacity right-sizing.
Workers on WA-based Amentum notices should contact the WA workforce agency directly, response teams, severance negotiation guidance, and TAA (Trade Adjustment Assistance) screening move fastest in the days immediately following a notice.

This record reflects filed notices only; subsequent hiring, rescinded closures, or facility reopenings are not tracked by WARN disclosures.
