Fonterra has posted a 53 per cent drop in interim net profit as high dairy commodity prices and processing constraints hit the dairy co-op's margins.
Net profit for the six months to January 31 was $217 million, down from $459 million a year earlier, the company said.
Fonterra said total revenue for the six month period rose 21 per cent to $11.3 billion, while normalised earnings before interest and tax (ebit) fell 41 per cent to $403 million.
The interim result covers the period of Fonterra's botulism false alarm in August, which resulted in a global recall of dairy products, mostly infant formula.
While high dairy prices are a boon for farmers, the cooperative's earnings are negatively impacted because it has to purchase the milk at the higher rates before processing it into consumer products like milk powder.
