# Nan Nan Resources flags swing to loss on bond valuation hit and weaker coal margins

An update from Nan Nan Resources Enterprise Limited ( (HK:1229) ) is now available.

Nan Nan Resources Enterprise Limited has warned that it expects to swing from a profit of about HK$71.79 million in the year ended 31 March 2025 to a loss of up to HK$10 million for the year ended 31 March 2026. The deterioration reflects pressure on its coal mining business, where higher costs and lower average selling prices are eroding margins and exposing the group to market volatility.

The anticipated loss is also driven by a HK$65.13 million loss from the fair value change of a HK$200 million zero-coupon convertible bond maturing in 2029, which is measured as a financial liability at fair value through profit or loss. The company said the figures are based on unaudited management accounts and may change, and it cautioned shareholders and potential investors to act carefully when dealing in its shares ahead of the full annual results due by end-June 2026.
