Eighth Consecutive Profitable Quarter

SINGAPORE, May 12, 2026 /PRNewswire/ -- LightInTheBox Holding Co., Ltd. (NYSE: LITB) ("LightInTheBox" or the "Company"), a global consumer lifestyle company, today announced its unaudited financial results for the first quarter ended March 31, 2026.

First Quarter 2026 Financial Highlights

“We are very pleased to report our eighth consecutive profitable quarter and a record first-quarter profit of $1.2 million since 2022, despite Q1 typically being our seasonally weakest period,” commented Jian He, CEO of LightInTheBox. “This marks our second consecutive quarter of year-over-year revenue growth, with revenues increased by 11% to $52 million. Our branded apparel business continued to gain momentum, growing over 81% year over year and accounting for 24% of total revenue, up from 15% in the first quarter of 2025.”

“These results reflect the continued progress of our transformation into a global consumer lifestyle company. By offering highly customized products that create deep emotional resonance for festivals, holidays, and special occasions, combined with our brand matrix strategy across women’s fashion, golf apparel, and light party dresses, we are driving stronger engagement and customer loyalty. With sustained profitability, disciplined cost control, and an ongoing share repurchase program, we believe we are well positioned to pursue continued revenue and profit growth, as well as greater shareholder value throughout 2026.” Mr. He concluded.

Share Repurchase Program

On March 31, 2025, the Company’s board of directors authorized a share repurchase program under which the Company may repurchase up to $0.7 million of its ordinary shares in the form of ADSs no later than June 30, 2025.

Non-GAAP Financial Measure

In evaluating the business, the Company considers and uses a non-GAAP measure, Adjusted EBITDA, as a supplemental measure to review and assess operating performance. The presentation of this non-GAAP financial measure is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The Company's non-GAAP financial measure excludes share-based compensation expenses, depreciation and amortization expenses, interest income, interest expenses and income tax benefit / (expense).

The Company presents this non-GAAP financial measure because it is used by management to evaluate operating performance and formulate business plans. The Company believes that the non-GAAP financial measure helps identify underlying trends in its business. The Company also believes that the non-GAAP financial measure could provide further information about the Company's results of operations and enhance the overall understanding of the Company's past performance and future prospects.

The non-GAAP financial measure is not defined under U.S. GAAP and is not presented in accordance with U.S. GAAP. The non-GAAP financial measure has limitations as an analytical tool. The Company's non-GAAP financial measure does not reflect all items of income and expenses that affect the Company's operations and does not represent the residual cash flow available for discretionary expenditures. Further, the non-GAAP measure may differ from the non-GAAP information used by other companies, including peer companies, and therefore their comparability may be limited. The Company compensates for the limitations by reconciling the non-GAAP financial measure to the nearest U.S. GAAP performance measure, all of which should be considered when evaluating performance. The Company encourages you to review the Company's financial information in its entirety and not rely on a single financial measure.

For more information on the non-GAAP financial measure, please see the table captioned "Unaudited Reconciliations of GAAP and Non-GAAP Results" set forth at the end of this press release.
