Datang Environment Industry Group (HKG:1272) expects a pre-tax profit of between 350 million yuan and 400 million yuan for the first half of 2025, down from 478 million yuan a year prior, a Thursday Hong Kong bourse filing said.

The firm attributed the forecast to lower revenue and profit from the desulfurization and denitrification concession projects, as well as the absence of a one-off revenue from certain projects seen in the prior-year period.
