Stellantis Backs Poissy Plant, Rules Out Closure and Mass Layoffs, Announces €20 Million Stamping Upgrade

Model allocation will be decided in a strategic plan due in the first half of 2026 under new CEO Antonio Filosa.

Overview

  • The company pledged an industrial future for Poissy and confirmed there will be no collective redundancy plan.
  • Production of the Opel Mokka and DS3 at the site is assured through 2028.
  • The €20 million modernization of stamping lines is presented as enabling more than 20 years of production.
  • Stellantis plans near‑term development of complementary activities, including aftermarket parts and circular‑economy work such as vehicle recovery and parts reuse.
