Thank you all for joining us on our fourth quarter and full year 2025 earnings conference call. Before we begin, I would like to note that the financial information and the non-GAAP numbers in this release are presented on a continuing operational basis and in RMB, unless otherwise stated. Let me begin with our latest business updates. In the fourth quarter of 2025, we continued to deliver steady progress in our core business, with top-line growth on a year-over-year and quarter-over-quarter basis. Our school-based subscription model business continued to expand, contributing a growing share in total revenue, emerging as a key contributor during the quarter. Meanwhile, we successfully launched our new consumer-facing product, Yiqi Aixue which is closely aligned with the national AI+ education initiative. Leveraging the brand recognition and user trust cultivated over the past decade, our new AI membership product has achieved strong presale orders and received highly positive market feedback since its launch, demonstrating its robust growth prospects in the quarters ahead. Notably, the robust presale demand for our new product generated a significant increase in free cash flow. As of quarter end, we maintained a healthy cash balance of RMB 407 million, reflecting the promising trajectory of our new AI-powered offerings and the positive expectations for future cash flow. Now let me go into more details. In the fourth quarter of 2025, we recorded net revenues of RMB 38.9 million, an increase of 94.6% on a quarter-over-quarter basis, and a 6.4% growth on a year-over-year basis. Driven by the growing contribution of recurring revenue on the subscription model, as well as our consistent commitment to cost control, growth was restored to a normalized level of 46.1% in Q4, a 12.5 percentage point increase on a year-over-year basis. Benefiting from sustained efficiency improvements, our net loss narrowed by 16.8% year-over-year. We also generated positive net operating cash inflow in the quarter, driven by the strong momentum of our new C-end business and continuous improvements in operational efficiency. During the quarter our school-based subscription model business maintained positive progress, contributing a growing share of total revenue. The increase in net revenues from this segment reflects its recurring nature as it continues to scale effectively. The steady progress of our school-based subscription business has not only strengthened our financial health, including gross margins and other key metrics, but also helped us reach a broader base of potential users and enhance brand influence, laying a solid foundation for the launch of our C-end business. In response to the national initiative of embedding AI throughout the entire educational process and guided by our mission to make learning a wonderful experience, during the quarter, we successfully rolled out our AI personalized learning membership product, Yiqi Aixue, targeting C-end users. Leveraging the user trust built over years, strong brand endorsement from our district-level and school-based projects as well as mature smart hardware capabilities and a solid AI foundation. This new AI membership product has garnered strong market enthusiasm and a robust pre-order volume. In the design of this product, we are committed to enabling users to achieve a more personalized, effective, and enjoyable learning experience in less time. It deeply integrates our hardware and software capabilities together with the extensive content resources we have built over the past decade. Our Smart Pen captures full process writing data while respecting traditional pen and paper habits. It efficiently digitalize handwritten notes and exercise responses, visualizing users' thinking process rather than simply uploading final answers. By visualizing these thinking patterns, we are able to deliver personalized learning diagnostics, generate AI-powered customized practice notes, and intelligently recommend similar learning exercises, enabling highly efficient and focused learning practice. Users' own notes taken with this endlessly with support for custom tags, categorization, and quick search. As a result, users can quickly identify their learning areas for improvement without spending extra time manually organizing paper notes, compiling practice notes, or searching for relevant problems. In addition, our AI planner provides study supervision based on personalized diagnostics and offers tailored learning plans aligned with the local learning schedules and individual progress. This allows users to focus on their growth areas and improve efficiently. These personalized practice and planning capabilities are backed by our 10 years of deep insights into local learning profiles, supported by massive data from large scale, regular, full scenario usage across our platforms. The product also features interactive tools, including AI Q&A and AI translation, et cetera, along with a suite of value-added learning resources. Notably, we have introduced Tuobitu Smart Rabbit, an intelligent learning companion that provides emotional support through natural voice interaction. It reminds users to study, offers encouragement, and makes the learning experience warmer and more engaging, helping users stay consistent with their personalized learning journeys. Looking ahead, we will continue to explore innovation practices in AI+ education and steadily reiterate and upgrade our products. Our business segments serving G-end, B-end, and C-end users will grow in synergy as we further strengthen our brand influence and enhance user value. The above concludes the business update.
