Winson Holdings Hong Kong (HKG:6812) expects a loss of HK$7 million for the six months ended Sept. 30, against a profit of HK$15.6 million logged for the same period last year, a Friday Hong Kong bourse filing said.

The environmental hygiene and related services provider attributed the turn to loss to a drop in gross profit and gross profit margins resulting from an increase in labor costs during the period, market competition, and an increase in general operating expenses.
