As inventories of the iPhone 6S and 6S Plus have piled up since they were launched last September, production will be scaled back to let dealers go through their current stock, the business daily reported.
The report prompted a 2.5% drop in Apple shares, which have lost about a quarter of their value from record highs in April, reflecting worries over slowing shipments.
Shares in the mainly Asian makers of the iPhones’ screens and chips were also sharply lower yesterday.
“This is an eye-opening production cut which speaks to the softer demand that Apple has seen with 6S out of the gates,” FBR Capital Markets analyst Daniel Ives said.
“The Street was bracing for a cut but the magnitude here is a bit more worrisome.”
Some Taiwanese suppliers pointed to falling sales, a rare holiday break, and a government subsidy as evidence of the gloomy outlook.
“The slowing down of the market is the truth,” one Taiwanese supplier said.
In China’s Henan province, the Zhengzhou capital city government said this week it had awarded 82m yuan (€12.53m) in subsidies to companies under Foxconn, a major iPhone assembler.
Officially called Hon Hai Precision Industry Co, Foxconn employs hundreds of thousands of workers in the province, and a subsidy of this kind suggests the government is concerned about the company’s ability to maintain its workforce, analysts said.
Another Taiwanese supplier said Foxconn had granted its factory workers time off around Chinese New Year, which falls on February 8, rather than follow its past practice of paying overtime to keep its production lines humming through the biggest holiday in China.
Hon Hai closed down 0.1%, but had been trading earlier at lows not seen in over four months.
Among LCD panel makers, Japan Display fell 4.7% while LG Display Ltd fell 3.4%.
TSMC, the world’s largest chipmaker which has supplied some of the chips used in Apple iPhones, fell 1.8%, while another Taiwanese assembler, Pegatron, ended 5.7%.
Other suppliers such as Japan’s Murata Manufacturing, Alps Electric, and TDK Corp fell by 3% or 4%.
Production is expected to return to normal in the April-June quarter, the Nikkei reported.
However, Patrick Moorhead, an analyst at Moor Insights & Strategy, said he was a bit sceptical about the production cut reports.
“Apple has been gaining significant market share in pretty much every region, and I’m not seeing a global slowdown,” Mr Moorhead said.
