In the fourth quarter of 2024, net revenues decreased by 10.8% to RMB483.5 million (US$66.2 million) from RMB541.7 million in the fourth quarter of 2023.The decrease was primarily driven by the decline in gross billings from post-secondary courses over the recent quarters, resulting in a year-over-year decrease in net revenues from post-secondary courses, partially offset by the year-over-year growth in revenues from sales of goods such as books and learning materials.

About Non-GAAP Financial Measures

We use gross billings, EBITDA, non-GAAP operating cost and expenses, non-GAAP income from operations and non-GAAP net income per share, each a non-GAAP financial measure, in evaluating our operating results and for financial and operational decision-making purposes.

We define gross billings for a specific period as the total amount of cash received for the sale of course packages, net of the total amount of refunds paid in such period. Our management uses gross billings as a performance measurement because we generally bill our students for the entire course tuition at the time of sale of our course packages and recognize revenue proportionally over a period. EBITDA is defined as net income excluding depreciation and amortization, interest expense, interest income, and income tax expenses. We believe that gross billings and EBITDA provide valuable insight into the sales of our course packages and the performance of our business.

These non-GAAP financial measures should not be considered in isolation from, or as a substitute for, their most directly comparable financial measures prepared in accordance with GAAP. A reconciliation of the historical non-GAAP financial measures to their respective most directly comparable GAAP measure has been provided in the tables included below. Investors are encouraged to review the reconciliation of the historical non-GAAP financial measures to their respective most directly comparable GAAP financial measures. As gross billings, EBITDA, operating cost and expenses excluding share-based compensation expenses, general and administrative expenses excluding share-based compensation expenses, sales and marketing expenses excluding share-based compensation expenses, product development expenses excluding share-based compensation expenses, income from operations excluding share-based compensation expenses, and basic and diluted net income per share excluding share-based compensation expenses have material limitations as an analytical metric and may not be calculated in the same manner by all companies, it may not be comparable to other similarly titled measures used by other companies. In light of the foregoing limitations, you should not consider gross billings and EBITDA as a substitute for, or superior to, their respective most directly comparable financial measures prepared in accordance with GAAP. We encourage investors and others to review our financial information in its entirety and not rely on a single financial measure.
