Wayfair's stock plunged 15.82% during intraday trading on Thursday, as investors reacted negatively to the company's fourth-quarter financial results which revealed a significant net loss.

While the online furniture retailer reported adjusted earnings per share of $0.85, surpassing analyst estimates of $0.69, and revenue of $3.34 billion that slightly exceeded expectations, the GAAP figures told a different story. The company posted a net loss of $116 million, resulting in a loss per share of $0.89, which fell far short of the modest profit analysts had anticipated.

The poor bottom-line performance was attributed to several factors, including a $165 million loss from the company's decision to repurchase some of its debt and costs related to equity-based compensation. Additionally, the company's active customer base declined by 0.5% year-over-year to 21.3 million, raising concerns about growth sustainability despite management's claims of market share gains.
