Itaconix plc

("Itaconix" or the "Company")

Production Resumed after Storm Damage

Itaconix (AIM: ITX) (OTCQB: ITXXF), a leading innovator in plant-based specialty polymers used as essential ingredients in everyday consumer products, is pleased to provide an update to the 4 November 2021 announcement regarding the temporary interruption to operations due to water damage.

The Company was successful with interim measures to resume production in the middle of November, with permanent repairs scheduled to be completed in the coming weeks.

Itaconix has met and expects to continue to meet all customer orders. The Company is working closely with one large customer on minor delivery delays that will not impact the customer's operating needs.

Itaconix has filed a claim with the relevant insurers to cover the costs of both property damage and operational costs incurred.
