The investment group listed in London ends in an agreement of 200 million pounds Sterling to buy three of the largest regional airports in Great Britain.
Sky News has learned that the ICG should sign a formal agreement to buy Bournemouth, Exeter and Norwich airports later this month.
The trio of sites collectively serves just over 2 million passengers per year.
ICG buys airports from Rigby Group, a private conglomerate that has interests in the hotels, software and technology sectors.
Exeter acted as the center of Flybe, the regional carrier which collapsed following the pandemic.
The agreement will take place in the midst of an activity frenzy involving the main British airports while infrastructure investors seek to use their assessments.
Avialliance, which belongs to the Canadian PSP Investments pension fund, agreed to buy the parent company of Aberdeen, Glasgow and Southampton airports for 1.55 billion pounds Sterling last year.
The basis of shareholders at London City airport has just been shaken with an agreement that saw Macquarie in Australia take a big stake.
The French investor Ardian has increased his investment at Heathrow airport, because the largest aviation center in the United Kingdom offers an expansion that will cost dozens of billions of pounds.
ICG and Rigby Group refused to comment.
