Manawa Energy's shares are in a trading halt pending a review of its earnings outlook which was expected to be less than the guidance it provided in May.
The renewable power generator was expecting underlying, for the year ending March 2025, to be in the range of $130m and $150 million.
However, it said earnings were likely to be down on guidance amid uncertainty about the recovery of money owed by a customer, as well as adverse market conditions.
The trading halt was expected to be lifted no later than the NZX market opening on Friday morning.
