SEOUL, Aug 7 (Reuters) - South Korean e-commerce company

Coupang Inc ( CPNG ) swung to a net loss in the second quarter

due to operating losses at its luxury online platform subsidiary

Farfetch and the estimated costs of a fine imposed by the

domestic antitrust watchdog.

The New York-listed company, which is backed by Japan's

SoftBank Group Corp ( SFTBF ), posted a net loss of $105 million

for the second quarter compared to a net profit of $145 million

in the same period last year.

Coupang ( CPNG ) bought Farfetch in a deal that provided the

struggling online luxury fashion retailer with $500 million in

capital to keep operating. The acquisition was completed in

January.

Farfetch has been hit by a slowdown in the luxury sector

which has complicated its efforts to make a profit on technology

investments and prompted recent credit rating downgrades.

"On Farfetch, as we stated last quarter, our goal is to

generate close to positive adjusted EBITDA on a run-rate basis

by the end of the calendar year," Bom Kim, Coupang's ( CPNG ) founder and

chief executive officer, told an earnings call.

"Though we're still in the very early stages of our journey,

we're excited about Farfetch's progress and potential," said

Kim.

In June, South Korea's antitrust regulator announced the

imposition of 140 billion won ($101.65 million) in fines against

Coupang ( CPNG ) for allegedly manipulating search rankings.

Coupang ( CPNG ) had said then that it did not believe its practices

violate any South Korean laws and would vigorously appeal the

watchdog's decision in court.

The company reported $7.3 billion in net revenues for the

April-June period, up 25% from a year ago.
