Listed infrastructure investor Infratil expects its underlying earnings to grow by as much as 10% in 2012 following pre-tax earnings of $443 million in the year to the end of March.
The company has announced pre-tax earnings of $443 million in the year to the end of March 2011 and is forecasting that it will increase that to between $460 million and $490 million in the 2012 financial year.
Infertil says the improvement is due to increased earnings for Wellington Airport, NZ Bus, Z Energy, and Trustpower - in which Infratil has a 51% stake.
It expects earnings in its Australian energy business to fall slightly.
Shares in Infratil fell 3 cents to $1.69 on Monday.
