CWT International (HKG:0521) expects to post profit after tax of at least HK$270 million for the six months ended June 30, up 99% or more from HK$136 million a year earlier, it said in a Wednesday Hong Kong bourse filing.

Shares of the logistics services provider gained nearly 4% in Thursday late-morning trade.

The company attributed the expected increase to stronger performance in its commodity marketing segment, driven by higher premiums and improved margins in its concentrates portfolio, as well as a tax credit recognised in the logistics services segment.

Interim results are due on or before Aug. 31.
