UP Fintech Holding Limited Reports Unaudited Second Quarter 2026 Financial Results

Singapore, August 26, 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 second quarter ended June 30, 2026.

Mr. Wu Tianhua, Chairman and CEO of UP Fintech stated: “In the second quarter, we saw substantial improvement in both commission income and interest related income compared with both the prior quarter and the same quarter of last year. Our total revenue for the second quarter reached US$182.3 million, hitting an all-time high and representing a sequential increase of 17.7% and a year-over-year growth of 31.4%. Income from operations for the second quarter reached US$56.8 million, representing a quarter-over-quarter increase of 19.5% and year-over-year growth of 12.6%. GAAP and non-GAAP net income attributable to UP Fintech reached US$39.4 million and US$42.8 million respectively, versus the GAAP and non-GAAP net losses of US$26.9 million and US$23.8 million in the prior quarter.

In the second quarter, we added 32,600 new funded clients, the great majority of which came from Singapore and Hong Kong markets. Our total funded accounts reached 1,315,400 at quarter end, representing a 10.3% year-over-year increase. We continued to generate solid net asset inflows from overseas retail users, which amounted to over $1.5 billion in the second quarter. Fueled by mark-to-market gains, total client assets stood at US$60.7 billion at the end of the second quarter, reflecting a 3.1% quarter-over-quarter increase and a 16.7% year-over-year growth. Client assets across all of our overseas markets posted quarter-over-quarter growth. In the Hong Kong market, we rolled out more offline client-acquisition initiatives and expanded branding exposure, driving local client assets up by nearly 30% quarter-over-quarter. Client assets in the Australia-New Zealand market and the U.S. market grew by more than 30% and nearly 50% quarter-over-quarter, respectively. This demonstrates that thanks to the diversified development of our core businesses and continued execution of our internationalization strategy, we have earned sustained trust and recognition from both new and existing users across all the markets we entered.

We continued to iterate localized functions and upgrade our product ecosystem to deliver a more streamlined and user-centric trading experience in the second quarter. For the Singapore market, we further enhanced localized trading capabilities by launching fractional share trading for Singapore-listed stocks and REITs. The initiative effectively lowered market entry barriers, making local investment more accessible and friendly to novice investors. Furthermore, to streamline users’ compliance procedures and reduce tax declaration complexities, we rolled out a dedicated tax reporting tool under our Hong Kong, Singapore and New Zealand regulatory licenses. The upgraded tool optimizes the end-to-end tax filing experience, enabling users to directly view and download annual tax reference documents via our mobile app and official website personal center. It comprehensively covers key tax data including trading profits and losses, dividend income, as well as interest and coupon earnings. Additionally, we launched “Cboe” index options trading in Hong Kong, and hosted a dedicated launch event for TigerX Cboe index options alongside a series of investor education initiatives, further enriching the range of trading products available to local investors.

Our corporate business continued to perform well in the second quarter of 2026. We underwrote 14 Hong Kong IPOs, including “CloudNavi” and “DeepZero”. We also participated in the distribution of four U.S. IPOs, among which were “DSOCHE” and “Micware”. Our ESOP business delivered steady growth during the quarter. We added 50 new ESOP clients in the second quarter, bringing our aggregate ESOP client served to 840 as of June 30, 2026.

To date, we have repurchased approximately US$5 million worth of our American Depositary Shares (“ADSs”), which represent the Company’s Class A ordinary shares. These buyback activities fall under the 12-month share repurchase plan we announced on June 2, 2026. Moving forward, we will assess market conditions and may execute additional buyback activities from time to time under the existing share repurchase program.”

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.
