Yuanda China (HKG:2789) expects to post a net profit between 150 million yuan and 210 million yuan for the six months ended June 30, up from about 6 million yuan a year earlier, according to a Thursday Hong Kong bourse filing.

Shares of the curtain wall systems maker surged nearly 63% in Friday morning trade.

The improvement was mainly driven by increased overseas orders under its internationalization strategy, which boosted revenue scale and higher exchange gains compared with the prior-year period.

Interim results are slated for release by the end of August.
