Wrth i'r broses o ddatrys yr anghydfod fynd rhagddi, mae Costain wedi gwneud dau ddatganiad rheoleiddiol, un ar ddiwedd 2019 ac un arall ym mis Medi 2020, i ddiweddaru’r marchnadoedd ac addasu lefel y refeniw yr oeddent yn disgwyl ei dderbyn o'r contract hwn. Deallaf fod Costain yn bwriadu rhoi diweddariad masnachu arall i gadarnhau bod yr anghydfod wedi cael ei ddatrys
As the dispute resolution process has progressed Costain have made two regulatory statements, at the end of 2019 and again in September 2020, to update markets and adjust the level of revenue they expected to achieve from this contract. I understand that Costain plans to provide a further trading update to confirm settlement of the dispute.
