Marketing services revenue was RMB189.4 million (US$26.6 million), compared with RMB256.6 million in the same period of 2024. The decrease was primarily due to our proactive and ongoing refinement of service offerings.

Paid membership revenue was RMB385.6 million (US$54.2 million), compared with RMB459.4 million in the same period of 2024. The decrease was primarily due to a decline in the number of our average monthly subscribing members.

Other revenues[3] were RMB83.9 million (US$11.8 million), compared with RMB129.0 million in the same period of 2024. The decrease was primarily due to the strategic refinement of our vocational training business.

Cost of revenues decreased by 16.3% to RMB255.3 million (US$35.9 million) from RMB304.9 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.

Use of Non-GAAP Financial Measures

In evaluating the business, the Company considers and uses non-GAAP financial measures, such as adjusted income from operations and adjusted net income, 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.
