Chinese wind group Goldwind said its first-half profits will be lower than expected due to delays in completing a deal with US technology giant Apple.

Goldwind now expects net profits for the January to June period to come in between 1.01bn yuan and 1.45bn yuan ($147m-$213m), after indicating in April it expected the range to be 1.45bn-2.17bn yuan.

The revised figure would leave the net result between flat and 30% lower when compared to the same period in 2016.
