Japanese food group Ezaki Glico has booked an increase in half-year net profit but saw operating profit and net sales fall.

The owner of the Pocky confectionery brand saw net profit double to JPY15.32bn (US$136.4m) thanks to the proceeds from a sale of fixed assets.

Operating income slid 3.1% to JPY9.48bn. Ezaki Glico pointed to higher promotion and advertising expenses.

The deconsolidation of Ezaki Glico's livestock processing business weighed on sales, which fell 2.3% to JPY165.73bn.
