Second Quarter 2025 Financial Results

Total revenues were RMB716.9 million (US$100.1 million) in the second quarter of 2025, compared with RMB933.8 million in the same period of 2024.

 1

Marketing services revenue was RMB222.8 million (US$31.1 million), compared with RMB344.0 million in the same period of 2024. The decrease was primarily due to our proactive and ongoing refinement of service offerings to strategically focus on margin improvement.

Paid membership revenue was RMB402.0 million (US$56.1 million), compared with RMB432.7 million in the same period of 2024. The slight decrease was primarily due to a decline in the number of our average monthly subscribing members.

Vocational training revenue was RMB62.1 million (US$8.7 million), compared with RMB133.6 million in the same period of 2024. The decrease was primarily due to the strategic refinement of our businesses.

Other revenues increased by 27.6% to RMB30.0 million (US$4.2 million) from RMB23.5 million in the same period of 2024.

Cost of revenues decreased by 28.8% to RMB268.7 million (US$37.5 million) from RMB377.3 million in the same period of 2024. The decrease was primarily due to reduced content and operating costs associated with the decline in our revenues, a decrease in personnel-related expenses and a decrease in cloud services and bandwidth costs resulting from our improved technological efficiency.

Gross profit was RMB448.2 million (US$62.6 million), compared with RMB556.5 million in the same period of 2024. Gross margin expanded to 62.5% from 59.6% in the same period of 2024, primarily attributable to our monetization enhancements and improvements in our operating efficiency.

Total operating expenses decreased by 27.2% to RMB539.2 million (US$75.3 million) from RMB740.4 million in the same period of 2024.

Selling and marketing expenses decreased by 21.8% to RMB326.3 million (US$45.5 million) from RMB417.0 million in the same period of 2024. The decrease was primarily due to more disciplined promotional spending and a decrease in personnel-related expenses.

Research and development expenses decreased by 30.4% to RMB145.7 million (US$20.3 million) from RMB209.3 million in the same period of 2024. The decrease was primarily attributable to improvements in our research and development efficiency.

General and administrative expenses decreased by 41.1% to RMB67.3 million (US$9.4 million) from RMB114.1 million in the same period of 2024. The decrease was primarily attributable to a decline in the allowance for expected credit losses on trade receivables and lower share-based compensation expenses.

Loss from operations narrowed by 50.5% to RMB91.0 million (US$12.7 million) from RMB183.9 million in the same period of 2024.

Adjusted loss from operations (non-GAAP)^[1] narrowed by 51.4% to RMB71.5 million (US$10.0 million) from RMB147.1 million in the same period of 2024.

 2

Investment income was RMB140.8 million (US$19.7 million), compared with RMB21.8 million in the same period of 2024. The increase was primarily attributable to unrealized gains as a result of re-measuring the fair value of our investment in a privately held company associated with an observable price change in the second quarter of 2025.

Net income was RMB72.5 million (US$10.1 million) in the second quarter of 2025, compared with a net loss of RMB80.6 million in the same period of 2024.

Adjusted net income (non-GAAP)^[1] was RMB91.3 million (US$12.8 million) in the second quarter of 2025, compared with an adjusted net loss of RMB44.6 million in the same period of 2024.

Diluted net income per American depositary share (“ADS”) was RMB0.88 (US$0.12), compared with a diluted net loss per ADS of RMB0.89 in the same period of 2024.

Cash and cash equivalents, term deposits, restricted cash and short-term investments

As of June 30, 2025, the Company had cash and cash equivalents, current and non-current term deposits, restricted cash and short-term investments of RMB4,820.8 million (US$673.0 million), compared with RMB4,859.0 million as of December 31, 2024.

Share Repurchase Programs

As of June 30, 2025, the Company had repurchased 31.1 million Class A ordinary shares (including Class A ordinary shares underlying the ADSs) for a total price of US$66.5 million on both the New York Stock Exchange and The Stock Exchange of Hong Kong Limited under the Company’s existing share repurchase programs.

Use of Non-GAAP Financial Measures

In evaluating the business, the Company considers and uses non-GAAP financial measures, such as adjusted income/(loss) from operations and adjusted net income/(loss), to supplement the review and assessment of its operating performance. The Company defines non-GAAP financial measures by excluding the impact of share-based compensation expenses, amortization of intangible assets resulting from business acquisitions and the tax effects of the non-GAAP adjustments, which are non-cash expenses. The Company believes that the non-GAAP financial measures facilitate comparisons of operating performance from period to period and company to company by adjusting for potential impacts of items, which the Company’s management considers to be indicative of its operating performance. The Company believes that the non-GAAP financial measures provide useful information to investors and others in understanding and evaluating the Company’s consolidated results of operations in the same manner as they help the Company’s management.

The non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. The presentation of the non-GAAP financial measures may not be comparable to similarly titled measures presented by other companies. The use of the non-GAAP financial measures has limitations as an analytical tool, and investors should not consider them in isolation from or as a substitute for analysis of our results of operations or financial condition as reported under U.S. GAAP. For more information on the non-GAAP financial measures, please see the tables captioned “Unaudited Reconciliations of GAAP and Non-GAAP Results” set forth at the end of this press release.
