Third Quarter 2025 Financial Results

Total Revenues

Total revenues were US$126.4 million, representing an increase of 57.7% year-over-year. The increase in total revenues was mainly attributable to the increased revenues generated from our major business operations.

Revenues from subscription were US$40.7 million, representing an increase of 22.3% year-over-year. The increase in subscription revenues was driven by the increase in the number of subscribers and the increased average revenue per subscriber. The number of subscribers was 6.56 million as of September 30, 2025, compared with 5.51 million as of September 30, 2024. The average revenue per subscriber for the third quarter was RMB44.2, compared with RMB40.9 in the same period of 2024. The higher average revenue per subscriber was due to the increased proportion of premium subscribers which have higher average revenue per subscriber.

Revenues from live-streaming and other services were US$49.1 million, representing an increase of 127.1% year-over-year. The increase was mainly due to the growth of our overseas audio live-streaming businesses as well as the advertising business.

Revenues from cloud computing were US$36.6 million, representing an increase of 44.9% year-over-year. The increase in cloud computing revenues was mainly attributable to the increased demand from major customers for our cloud computing services.

Costs of Revenues

Costs of revenues were US$65.4 million, representing 51.7% of our total revenues, compared with US$39.4million, or 49.1% of the total revenues, in the same period of 2024. The increase in costs of revenues was mainly attributable to the increase in bandwidth costs and revenue-sharing expenses in our overseas audio live-streaming operations, generally in line with the growth in revenues.

Bandwidth costs, as included in costs of revenues, were US$38.3 million, representing 30.3% of our total revenues, compared with US$24.8 million, or 31.0% of the total revenues, in the same period of 2024. The increase in bandwidth costs was primarily due to the increased sales of our cloud computing services.

The remaining costs of revenues mainly consisted of revenue-sharing costs for our live streaming business and payment handling charges.

Gross Profit and Gross Profit Margin

Gross profit for the third quarter of 2025 was US$60.5 million, representing an increase of 49.6% year-over-year. Gross profit margin was 47.9% in the third quarter of 2025, compared with 50.5% in the same period of 2024. The increase in gross profit was mainly contributed by our online advertising business, overseas audio live-streaming business and subscription business. The decrease in gross profit margin was mainly attributable to the decreased gross profit margin of our cloud computing business and higher proportion of the revenue derived from our audio live-streaming business, which has a lower gross profit margin.

Research and Development Expenses

Research and development expenses for the third quarter of 2025 were US$21.0 million, representing 16.6% of our total revenues, compared with US$17.7 million, or 22.1% of our total revenues, in the same period of 2024. The increased expenses were primarily due to the increase in labor costs as compared with the same period of 2024.

Sales and Marketing Expenses

Sales and marketing expenses for the third quarter of 2025 were US$25.8 million, representing 20.4% of our total revenues, compared with US$11.5 million, or 14.3% of our total revenues, in the same period of 2024. The increases were primarily due to more marketing expenses incurred during the quarter for our subscription and overseas audio live-streaming businesses as part of our ongoing efforts on user acquisition.

General and Administrative Expenses

General and administrative expenses for the third quarter of 2025 were US$10.9 million, representing 8.6% of our total revenues, compared with US$11.4 million, or 14.2% of our total revenues, in the same period of 2024. The decreased expenses were primarily due to the decrease in labor costs, partially offset by the increase in provision for litigations and share-based compensation expenses during the third quarter of 2025.

Operating Income/(Loss)

Operating income was US$2.7 million, compared with an operating loss of US$0.2 million in the same period of 2024. The increase in operating income was primarily attributable to the increase in gross profit, partially offset by the increase in marketing and other operating expenses during the quarter.

Other Income, Net

Other income, net was US$547.7 million, compared with other income, net of US$4.8 million in the same period of 2024. The increase was primarily attributed to fair value changes from our long-term investment in Arashi Vision Inc., which completed its initial public offering in June 2025.

Net Income /Earnings Per ADS

Net income was US$550.1 million compared with net income of US$4.4 million in the same period of 2024. The increase in net income was primarily due to the increase in other income as mentioned above. Non-GAAP net income was US$5.3 million in the third quarter of 2025, compared with US$4.9 million in the same period of 2024. The increase in Non-GAAP net income was primarily due to the increase in operating income.

Diluted income per ADS in the third quarter of 2025 was US$8.60 compared with diluted earnings per ADS of US$0.07 in the third quarter of 2024. Non-GAAP diluted earnings per ADS was US$0.09 in the third quarter of 2025, compared with non-GAAP diluted earnings per ADS of US$0.08 in the same period of 2024.

Cash Balance

As of September 30, 2025, the Company had cash, cash equivalents and short-term investments of US$284.1 million, compared with US$275.6 million as of June 30, 2025. The increase was mainly due to the increase in net cash inflow from operating activities during this quarter.

Guidance for the Fourth Quarter of 2025

For the fourth quarter of 2025, Xunlei estimates total revenues to be between US$131 million and US$139 million, and the midpoint of the range represents a quarter-over-quarter increase of approximately 6.8%.

About Non-GAAP Financial Measures

To supplement Xunlei's consolidated financial results presented in accordance with United States Generally Accepted Accounting Principles ("GAAP"), Xunlei uses the following measures defined as non-GAAP financial measures by the United States Securities and Exchange Commission: (1) non-GAAP operating income, (2) non-GAAP net income, (3) non-GAAP basic and diluted earnings per share for common shares, and (4) non-GAAP basic and diluted earnings per ADS. The presentation of the non-GAAP financial information is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP.

Xunlei believes that these non-GAAP financial measures provide meaningful supplemental information to investors regarding the Company's operating performance by excluding share-based compensation expenses, impairment loss of goodwill, and fair value changes of long-term investments, which are not expected to result in future cash payments, may recur from period to period but are subject to significant market volatility, and which are not indicative of our core operating results and business outlook. These adjustments do not affect the recognition or measurement of these items under GAAP but are presented solely to supplement investors’ understanding of our operating performance.

These non-GAAP financial measures also facilitate management's internal comparisons to Xunlei's historical performance and assist the Company's financial and operational decision making. A limitation of using these non-GAAP financial measures is that these non-GAAP measures exclude certain items that have been and will continue to be for the foreseeable future a recurring item in Xunlei's results of operations. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from each non-GAAP measure. The accompanying reconciliation tables at the end of this release include details on the reconciliations between GAAP financial measures that are most directly comparable to the non-GAAP financial measures the Company has presented.

The Company has not recast prior period non-GAAP measures in 2024 to exclude fair value changes of long-term investments, as such amounts in prior periods were immaterial and would not affect investors’ understanding of period-to-period comparisons.
