Wayfair (W) - Get Report shares were tumbling 18.3% to $82.63 Thursday after the furniture and home goods company reported a greater-than-expected third-quarter loss.

The Boston-based company reported a net loss of $272 million, or $2.94 a share, compared with a loss of $151.7 million, or $1.69 a share, a year ago. The adjusted loss was $2.23, which was much wider than Wall Street's expectation of a loss of $2.08.

Revenue totaled $2.31 billion, up from $1.71 billion a year ago, beating analysts' expectations for $2.28 billion.

The number of active customers in the direct retail business reached 19.1 million as of Sept. 30, up 37.6% year over year. Direct retail net revenue, consisting of sales generated primarily through Wayfair's sites, increased $607.2 million to $2.3 billion, up 35.9% year over year.

Repeat customers placed 6.1 million orders in the third quarter of 2019, an increase of 33.6% last year.

"This period of strong growth took place, despite some short-term tariff related volatility," said Niraj Shah, CEO, co-founder and co-chairman. "We could not be more confident in the future growth of the business. Our business continues to benefit from meaningful long term investments that directly and dramatically impact the customer experience further propelled by a massive structural shift in shopping behavior from offline to online."

In June, Wayfair employees walked out the company and gathered in Boston's Copley Square to protest Wayfair selling furniture to the operators of the migrant detention camps along the U.S. southern border. In August, Shah said the company and employees "are engaged in a constructive dialogue" over the issue, according to the Boston Business Journal.
