CESPIRA SIGNS AGREEMENT TO SUPPLY COMPONENTS FOR A CUSTOMER TRUCK TRIAL

Cespira, Westport Fuel Systems Inc.'s joint venture with the Volvo Group, has signed an agreement with and received full payment from a leading OEM (original equipment manufacturer) for Cespira's HPDI components to be utilized in a customer truck trial.

Cespira will deliver several hundred sets of a key component in support of the trial. The truck trial is designed to assess the market interest and viability of the direct injection system in certain heavy-duty trucking markets and is expected to form the basis upon which the OEM will determine whether to make a further investment to commercialize this system. It is also important to note that some of the other system components not supplied by Cespira and used during the trial have not been validated by Cespira. Further information regarding the trial is not disclosed for commercially sensitive reasons.
