First Half 2025 Results

Total net revenues were US$95,000, representing an increase of 100% from US$nil in the first half of 2024. The revenue increase was mainly due to provision of consulting services relating to design and development of electric vehicles to customers.

Gross profit was US$95,000, resulting from rendering consulting services.

Operating expenses were US$8.7 million, significantly higher than that of US$5.7 million in the first half of 2024. The difference in operating expenses between the two periods was largely due to the increase of US$3.8 million in general and administrative expenses.

General and administrative expenses were US$8.7 million, compared to that of US$4.9 million in the first half of 2024.

About Non-GAAP Financial Measures

To supplement Kaixin’s consolidated financial results presented in accordance with United States Generally Accepted Accounting Principles (“GAAP”), Kaixin uses “adjusted loss from operations” and “adjusted net loss”, which are defined as non-GAAP financial measures by the SEC, in evaluating its business. We define adjusted loss from operations as loss from operations excluding share-based compensation expenses. To facilitate investors and analysts, we present the foresaid impact in “Reconciliation of non-GAAP results of operations measures to the comparable GAAP financial measures” retrospectively. We present adjusted loss from operations and adjust net income (loss) because they are used by our management to evaluate our operating performance. We also believe that these non-GAAP financial measures provide useful information to investors and others in understanding and evaluating our consolidated results of operations in the same manner as our management and in comparing financial results across accounting periods and to those of our peer companies.

These non-GAAP financial measures are not intended to be considered in isolation from, or as a substitute for, the financial information prepared and presented in accordance with GAAP.
