(Corrects TSMC’s earlier capex estimate in the second paragraph to $11.5-12 billion, not $10.5-11 billion)
* Q2 profit T$72.29 bln vs T$71.895 bln analyst view
* Q2 revenue in line with company forecast
* Demand for high-end chips likely to slow -analysts
TAIPEI, July 19 (Reuters) - Taiwan Semiconductor Manufacturing Co Ltd cut its annual revenue and capital expenditure estimates on Thursday, as the world’s largest contract chipmaker braces for slowing growth in the smartphone and cryptocurrency mining industries.
TSMC, which makes chips for technology giants such as Apple Inc, Qualcomm Inc and Nvidia Corp, its lowered 2018 revenue growth forecast to a high single digit percent from 10 percent previously, and trimmed its expected capex range to $10-10.5 billion from $11.5-12 billion.
For the April-June, TSMC reported a 9 percent rise in net profit from a year earlier to T$72.29 billion ($2.36 billion), in line with market estimates, on strong demand for high-end chips used in cryptocurrency mining.
Revenue rose 11 percent to US$7.85 billion, the middle of the US$7.8 billion to US$7.9 billion range TSMC forecast in April.
Sales to the personal computer industry accounted for 21 percent of total revenue, from 8 percent a year prior, while revenue from the communications sector that includes smartphones fell to 48 percent from 58 percent.
The firm could face slowing demand for high-end chips used in cryptocurrency mining as miners switch to lower-powered chips due to price volatility as well as increased regulatory scrutiny of the sector, analysts said.
“We anticipate our business will benefit from new product launches ... while cryptocurrency mining demand will decrease from the second quarter,” Chief Financial Officer Lora Ho told analysts.
An intensifying trade spat between the United States and China could also be a near-term risk for TSMC, which has many of its biggest clients in mainland China, analysts said.
Revenue from China jumped to 23 percent from 11 percent a year earlier, though North America remains its biggest market with 53 percent of total revenue, down from 59 percent.
Prior to the earnings announcement, shares in TSMC closed up 0.67 percent versus a flat wider market. The stock has slipped less than 1 percent so far this year. ($1 = 30.5070 Taiwan dollars) (Reporting by Yimou Lee and Jess Macy Yu Editing by Christopher Cushing)
