Rome 23 January 2023 - Maire Tecnimont S.p.A. announces that, through its subsidiary NextChem Holding S.p.A., it is expanding into the high-valuederivates and biodegradable plastic by-productslicensing markets with the acquisition of an 83,5% stake of Conser, a technology licensor and process engineering design company based in Rome, Italy. Founded more than Fifty years ago, Conser has been developed by Flavio Simola, who has led the company to the current technological excellence. The closing, which is subject to customary conditions, is expected to take place by April 15, 2023. NextChem Holding also retains an option to acquire the remaining 16.5% stake within the next 3 years. The acquisition of Conser, which is expected to reach total revenues of approximately €25 million in 2022, is strategically important because it allows the Group to enter new markets.

Conser has a portfolio of technology patents dedicated to the energy transition and added-value specialty chemicals processes. Such a portfolio includes cost-effective and process-flexible technologies for Maleic Anhydride, Butanediol and Dimethyl Succinate, which are crucial building blocks for the production of biodegradable plastics, in particular Polybutylene Succinate (PBS) and polybutylene adipate co- terephthalate (PBAT). Conser's portfolio also includes technologies for Liquid

Organic Hydrogen Carriers, specialties for Lithium-based batteries production and Bio-based (vegetable glycerine) derivatives.

PBS and PBAT have excellent biodegradation properties, and their relevant consolidated markets show very promising outlooks driven by a growing demand
