Yaskawa, one of the world's biggest industrial robot manufacturers, forecast profit at 53 billion yen ($491.74 million) for the year ending February, down 10 percent from the previously estimated 59 billion yen.

The ongoing trade dispute has turned smartphone and other manufacturers in China cautious about investment, leading to a steeper-than-expected fall in orders for servo motors, the company said.

The revised outlook missed the 56.92 billion yen average of 23 analyst estimates in a Refinitiv poll.

The slowdown in automation equipment demand in China has weighed on Yaskawa's share price, sending the stock down by 18 percent since the company first lowered its profit outlook on Oct 10.
