UP Fintech Holding Limited Reports Unaudited First Quarter 2026 Financial Results

Singapore, June 2, 2026 – UP Fintech Holding Limited (NASDAQ: TIGR) (“UP Fintech” or the “Company”), a leading online brokerage firm focusing on global investors, today announced its unaudited financial results for the first quarter ended March 31, 2026.

Mr. Wu Tianhua, Chairman and CEO of UP Fintech stated: “In the first quarter, we continued to expand our user base and client assets, while further optimizing our comprehensive product offerings. Supported by these solid fundamentals, both our topline and operating performance have achieved notable year-over-year growth. Our total revenue for the first quarter reached US$154.9 million, representing a 26.3% increase year over year. Net loss and non-GAAP net loss attributable to UP Fintech for the quarter were $26.9 million and $23.8 million, versus net income of $30.4 million and $36.0 million in the same quarter last year. Recently on May 22, the Beijing Bureau of the China Securities Regulatory Commission (CSRC) issued administrative penalties and ordered the confiscation of illegal gains against certain subsidiaries of the Company, with a total amount of approximately RMB 411 million (equivalent to roughly $59.7 million). The penalties stemmed from certain subsidiaries’ unlicensed cross-border securities business and illegal activities relating to the fund and futures business in mainland China. The Company sincerely accepts the penalty and has recognized it as a subsequent significant event for the first quarter. Considering the Company’s overall profitability and cash flow position, this one-off expense will not have a material adverse impact on our business operations or long-term development.

In the first quarter, we added 28,900 new funded clients, with great majority of which came from Singapore and Hong Kong markets. Our total funded accounts reached 1,282,800 at quarter end, representing an 11.3% year-over-year increase. We continued to see solid net asset inflows, which amounted to $2.9 billion in the first quarter. It marks the first time in our history that quarterly net asset inflow above $2 billion from consolidated retail accounts, further demonstrating solid progress delivered by our client quality focused strategy. The overall market trended downward in the first quarter, driven by the pullbacks across financials, technology and consumer discretionary sectors. This caused $4.9 billion mark to market losses in client assets, led our total client assets down 3.2% quarter on quarter, though it still achieved a solid 28.4% year over year growth to reach $58.9 billion at quarter end. Nasdaq has since staged a rebound in the second quarter, and all mark to market losses on client assets recorded in the first quarter have been fully recovered on a quarter-to-date basis.

We continued optimizing products and elevating user experience. This quarter, we upgraded Tiger AI to a Multi-Agent structure, splitting functions like search, analysis, forecasting and risk control into standalone agents for more accurate outputs. In addition, we launched the Futures-focused Agent in the first quarter, which greatly improves accuracy and practicality in future-related inquiries and effectively lifts user satisfaction with Tiger AI’s futures service capabilities. Also, beyond its original dual-model setup, Tiger AI has now integrated with the Claude model, evolving into a triple-model intelligent assistant. Additionally, we further expanded our derivatives trading offerings by officially launching Hong Kong index options trading, alongside the TWAP (Time-Weighted Average Price) order function for options.

Our corporate business continued to perform well in the first quarter of 2026. We underwrote 10 Hong Kong IPOs, including industry-leading AI players “MiniMax” and “Zhipu AI”. We also completed two major U.S. SPAC IPOs, namely Fortress Value Acquisition Corp. V and KPET Ultra Paceline Corp. Additionally, investor demands for Hong Kong IPO subscriptions remained strong, the total subscription amount on the Tiger platform has exceeded HK$1 trillion year-to-date in 2026. In our ESOP business, we added 42 new clients in the first quarter, bringing our aggregate ESOP client count to 790 as of March 31, 2026.

To demonstrate our confidence in the Company's long-term growth prospects and our commitment to delivering shareholder value, our board of directors has approved a share repurchase program of up to US$50 million, to be implemented over a 12-month period from June 1, 2026.”

Use of Non-GAAP Financial Measures

In evaluating our business, we consider and use non-GAAP net loss or income attributable to ordinary shareholders of UP Fintech and non-GAAP net loss or income per ADS - diluted as supplemental measures to review and assess our operating performance. The presentation of the non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with the United States Generally Accepted Accounting Principles (“U.S. GAAP”). We define non-GAAP net loss or income attributable to ordinary shareholders of UP Fintech as net loss or income attributable to ordinary shareholders of UP Fintech excluding share-based compensation. Non-GAAP net loss or income per ADS - diluted is non-GAAP net loss or income attributable to ordinary shareholders of UP Fintech divided by the weighted average number of diluted ADSs.

We present these non-GAAP financial measures because they are used by our management to evaluate our operating performance and formulate business plans. Non-GAAP net loss or income attributable to ordinary shareholders of UP Fintech enables our management to assess our operating results without considering the impact of share-based compensation. We also believe that the use of these non-GAAP financial measures facilitates investors' assessment of our operating performance.

These non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. These non-GAAP financial measures have limitations as an analytical tool. One of the key limitations of using these non-GAAP financial measures is that they do not reflect all items of income and expenses that affect our operations. Share-based compensation has been and may continue to be incurred in our business and are not reflected in the presentation of non-GAAP net loss or income attributable to ordinary shareholders of UP Fintech. Further, these non-GAAP financial measures may differ from the non-GAAP financial information used by other companies, including peer companies, and therefore their comparability may be limited.

These non-GAAP financial measures should not be considered in isolation or construed as alternatives to total operating costs and expenses, net loss or income attributable to ordinary shareholders of UP Fintech or any other measure of performance or as an indicator of our operating performance. Investors are encouraged to review these historical non-GAAP financial measures in light of the most directly comparable GAAP measures. These non-GAAP financial measures presented here may not be comparable to similarly titled measures presented by other companies. Other companies may calculate similarly titled measures differently, limiting the usefulness of such measures when analyzing our data comparatively. We encourage investors and others to review our financial information in its entirety and not rely on a single financial measure.
