Last month, cyclone Michaung flooded a large part of the southern Indian state, which is home to 13 of Hatsun's 20 milk processing plants and, according to ICICI Securities, accounts for over half of the company's revenue.

The Chennai-based company's profit after tax rose 23.6% to 574 million rupees ($6.91 million) in the three months ended December 31, its slowest since the 2023 March quarter.

Total expenses, led by raw material costs, rose 11.2%. This offset Hatsun's 11.3% rise in revenue - the highest revenue growth the company has recorded since the 2023 March quarter, coming on the back of a productive flush season.

The flush season runs from October to February, as lower temperatures lead to higher milk production, and is used by dairies to build supply for the lean season.

Rivals Heritage Foods and Dodla Dairy will report third-quarter results later this month.

Shares of Hatsun Agro rose as much as 3.7% to hit a four-month high after the results, before giving up all the gains to trade 2.1% lower.
