Shares of Glasgow-based temporary power giant Aggreko plc rose about 4% on Wednesday after it announced it agreed contract revisions with The Tokyo Organising Committee of the Olympic and Paralympic Games “to reflect both scope changes and the impact of the delay of the Games into this year.”

Aggreko said the revenue value the contract is now expected to be around $315 million.
