Speaking at a briefing on the company's earnings for the year to June 30, Binns said that while he was not leaving Meridian until the end of the year, he would hand over the day to day running of the company to the CEO-elect Neal Barclay, who has served in senior management positions across the business in the last nine years, from Nov. 1.
In specific comments on the company's performance in the last year, Binns said it was notable that there was almost no discussion of the potential for the Rio Tinto-controlled aluminium smelter either to announce its closure or a reduced demand for electricity.
The smelter is Meridian's largest single customer, consumes around one-seventh of the country's total electricity production and has been subject in recent years to constant speculation as to its commercial viability.
Binns said that "the smelter is now in my view in a far better position than it has been in my five and a half years".
In answer to questions, Binns acknowledged Australian media speculation about metals giants Glencore and US-based Century Aluminium were "circling" the Australasian smelters and other aluminium production assets owned by Pacific Aluminium, the bundle of assets that Rio Tinto has sought a buyer for in the past.
There's been a lot of speculation that I might be going to Fletcher Building either as CEO or as a director. Read my lips: the answer is that I will not be.
"We will just have to wait and see how that all goes," said Binns. "If I was going to own a smelter, I would rather own a smelter in New Zealand than Australia."
That was less because of the volatility of Australian energy prices than the potential for Australian metals producers not to be able to secure the energy supplies required to maintain operations.
"There are real issues around energy security in Australia", where he said energy policy had become "incoherent", with renewable energy target planning apparently bogged down and the volatility in prices and threats of retail price regulation in Victoria potentially leading to a slow down in growth in its Powershop operations, which launched in Queensland during the last financial year.
Meridian reported flat earnings for the year to June 30, reflecting a strong first-half performance offset by dry conditions in the South Island that limited its ability to generate electricity from its southern hydro dams.
Net profit was $197 million, up from $185 million the year before, but on its preferred measure of earnings before interest, tax, depreciation, amortisation and changes in the value of financial instruments (ebitdaf), earnings were just 5 per cent up on the previous year at $653 million.
The result was achieved on total revenues of $2.319 billion, from $2.375 billion the previous year and total expenses of $1.666 billion, compared with $1.725 billion.
The shares edged up 0.2 per cent to $2.95.
