Trustpower, which spun out its Australian windfarms into a separately listed company, Tilt Renewables, on October 31, posted a 7.6 percent decline in first-half profit on a demerged basis, in the face of rising operating expenses and costs related to the split.
Profit was $45 million in the six months ended September 30, from $48.7m a year earlier, the Tauranga-based company said in a statement.
Revenue climbed to $501.6m from $474.8m.
The demerger created a separate company in Tilt that was valued at about $657m, based on the value of its shares on the NZX and ASX, which were distributed to existing shareholders.
Based on figured adjusted for the split, Trustpower's operating expenses rose to $392m from $354m a year earlier, driven by increases in line costs, generation production costs, wages and 'other expenses'.
Earnings included $8.7m of demerger expenses and one-time costs associated with the closure of the company's Energy Direct brand, it said on Monday.
Trustpower shares were unchanged at $4.79. The company declared an interim dividend of 16 cents a share, payable on December 9, from 21 cents a year earlier when the company included its Australian windfarms.
