GUANZE MEDICAL (02427.HK) issued a profit warning, expecting to record a loss of no more than 1 million yuan RMB for the six months ending June this year, while a profit of approximately 15.9 million yuan RMB was recorded for the same period last year. The board of directors believes that the expected losses are mainly due to the average selling price and quantity of medical imaging films sold, which has led to a decrease in revenue of about 34.4 million yuan RMB.
