Hebei Yichen Industrial Group (HKG:1596) expects to post a net profit of about 333.6 million yuan for 2025, compared with a net loss of about 57.7 million yuan a year earlier, according to a March 13 Hong Kong bourse filing.

Shares of the rail fastening manufacturer surged over 80% in Monday afternoon trade.

The anticipated improvement was attributed to higher shipment volumes of railway fastening system products and lower raw material procurement prices.

The company said its annual results are expected to be released in March.
