Johnson Electric Holdings' first-half profit jumped 22.4 per cent from a year earlier to US$80.26 million.
The results for the six months to September 30 were at the low end of analysts' expectations for the micro-motor manufacturer.
It struck a dividend of 0.38 US cent, down from 1.3 US cents previously. However, when Johnson Electric's four-for-one share split in August was taken into account, the dividend grew 20 per cent, the company said.
Turnover rose 34.9 per cent in the half, against the equivalent period last year, to US$395.21 million.
Analysts expressed worries about sluggish growth in the sales of micro-motors to the vehicle industry.
The company also manufactures components for power tools, home appliances, business equipment and personal care products.
'The greatest concern is the automotive sector,' Indosuez W I Carr Securities analyst Alan Wong said.
