The company lowered its expectation to 1,515 million kilograms of milk solids (kgMS) from the prior forecast of 1,530 million kgMS.

While it maintained its full-year adjusted earnings guidance and farmgate milk price range, the company flagged "significant risks" in the second half from the coronavirus outbreak.

"We have already contracted a high percentage of our 2020 financial year's milk supply and this is helping us manage the impact of coronavirus," the company said in a statement.

Fonterra said it would provide a further update on the impact of the epidemic on its business when it releases its interim results next month.
