Shares in The A2 Milk Company have plummeted after the New Zealand-based dairy firm said full-year sales revenue would be lower than analysts had forecast.
A2 said today it expects revenue for the 12 months to June 30 to rise as much as 67 per cent to between $NZ900 million and $NZ920 million ($A826.8 million and $A845.2 million), but that was lower than analysts had expected.
Deutsche Bank had forecast $NZ923 million in sales after A2 unveiled a strong first-half result in February, and reiterated its expectation in March.
A2's ASX-listed shares fell as much as 20 per cent at the open before recovering slightly.
The dual-listed firm's shares fared even more poorly on the NZ exchange, dragging the overall market lower with a fall of about 20 per cent before recovering some of that lost ground.
In a third-quarter trading update, A2 said revenue for the nine months to March 31 was $NZ660 million, up about 70 per cent from the same time a year ago and more than the $NZ549.5 million in the whole of FY17.
Driving the performance was growth in both nutritional products and liquid milk, as well as seasonal sales from key selling events in China.
The strong analyst forecasts had come after the company doubled its first-half profit to $NZ98.47 million on the back of strong growth in infant formula and liquid milk sales in core markets.
It lifted revenue 70 per cent to $NZ434.7 million and secured an alliance with global dairy giant Fonterra to produce new products and expand into new markets.
