Banpu is confident of getting approval but withdrew its FIRB application earlier this week because of the pending federal election.
The FIRB application will be resubmitted in the coming weeks while the company will hold an extraordinary general meeting of shareholders in Bangkok on August 10.
Banpu’s takeover offer at $6.20 per share on July 5 was made at a 40% premium to the closing price of Centennial shares on the previous trading day.
A year ago, Centennial shares were struggling to surpass $3, but closed down 4c to $5.98 on Friday.
