Thanks, Chris. And next, I'll go over the revenue for vertical application that includes financial risk management and market intelligence. Overall, Vertical Applications had a good quarter where revenue grew both year-over-year and quarter-over-quarter. And within vertical application, financial risk management recorded a strong 43% growth in revenue year-over-year and 12% quarter-over-quarter. Financial Risk Management delivered another excellent performance. We recorded robust revenue growth of 43% year-over-year and 11% quarter-over-quarter. Notably, this segment achieved revenue of more than RMB 22 million in each of the 4 quarters in 2025. In particular, the strong year-over-year performance was driven by impressive 20% in customer number growth and a 20% increase in ARPU. The customers that we signed up or renewed in Q4 include, but not limited to ChongXiing, Xiao, Chengduinhang and many more licensed credit or financial institutions throughout China. Market Intelligence revenue, on the other hand, decreased by 24% year-over-year and 3% quarter-over-quarter due to the continued weak market demand for Chinese APP data. This result is in line with our expectation. Next, I'll go over some of the profit and loss items. Our gross profit delivered another exceptional quarter, growing 23% year-over-year and 9% quarter-over-quarter. The RMB 69.7 million gross profit we had also was the highest gross profit recorded among any of the past 16 quarters. In this quarter, our revenue grew 13% year-over-year, yet our gross profit grew by 23% year-over-year. Notably, we saw this trend in Q3 as well. This tells a clear story. We are strengthening our ability to generate high-quality revenue with higher margins. Our strong gross profit number has proven instrumental in bringing us to a full year profitability in 2025. On net profit, after 3 consecutive profitable quarters, we have landed ourselves in a new territory, our first ever full year GAAP net profit for 2025. This is a great way for us to conclude our brilliant Q4 and full year 2025 story on a high note. On to operating expenses. Q4 operating expenses was at RMB 68.2 million, up 13% year-over-year and 6% quarter-over-quarter. Overall, we are pleased with the trending of OpEx to support revenue and profitability growth. I'll now dive deeper into the individual OpEx category. R&D expenses increased 16% year-over-year to RMB 28.3 million, mainly due to the higher staff costs and associated expenses. Technical service fee also contributed to the year-over-year increase in R&D expenses. Selling and marketing expenses increased by 16% as well year-over-year and to RMB 28.4 million, mainly due to the higher sales commission in line with the revenue growth and cash collection recorded in this quarter. Marketing expenses for investment in global business expansion also contributed to the year-over-year increase in SMS -- in selling and marketing expenses. G&A expenses remained flat at RMB 11.4 million, representing no change from the same quarter of last year. Next, I will share 3 very important KPIs that we closely monitor. Our net dollar retention rate, NDR, a commonly used KPI for SaaS companies stood at 103% for our core developer subscription business for the trailing 12-month period ended December 31, 2025. This is the second consecutive quarter where the NDR number has exceeded the 100% threshold. We are proud of this number as this demonstrates how our SaaS business model is widely accepted by the market. Customers have increased their spending on our platform over time. Secondly, another financial KPI for tracking the performance of SaaS company is the total deferred revenue. This represents cash collected in advance from customers for future contract performance, which exceeded the historical high we had last quarter and stood at RMB 178.7 million in Q4 of 2025. This historical high deferred revenue balance is a hallmark of high-quality, scalable business. It signifies strong customer loyalty, predictable future revenues, healthy cash flow and an effective sales strategies. Thirdly, we continue to maintain a healthy level of AR turnover days at 37 days. This number is simply fantastic. It shows we are collecting cash quickly and effectively. And this has really improved our financial liquidity while mitigating the risk of bad and doubtful debts. And there was no shortcut to achieving this. It was simply due to the result of our team's diligence, hard work and timely effort to engage with customers. On to the cash flow. We recorded yet another great number this quarter. For the quarter ended December 31, we recorded net operating activity cash inflow of RMB 35.1 million. This exceeds the last quarter and is now our best quarterly cash flow result since Q4 of 2020. Another metric to share with you, between the years, our cash and cash equivalent balance has increased by RMB 53.8 million. It represents a whopping 45% increase to RMB 173 million as of December 31, 2025. This reflects not only the significant step-up in our financial results, but also a meaningful improvement in the overall quality of our operations. Now let me take a few minutes here to recap. As you have heard Chris mention a year of pure brilliance at the beginning of this call. And throughout the entire 12 months of 2025, we have been operating under a high level of focus and rigor together with financial discipline. Our financial profile has fundamentally improved and moving in the right direction. And we closed a very strong and exceptional fiscal 2025. The numbers we have presented today speak for themselves. And this quarter, we achieved many historical milestones. Each one, a strong statement about the exceptional 2025 we have had and each one building momentum as we look forward to the next 12 months ahead of 2026. First, we achieved our very first full year GAAP net profit in history. Number two, the group quarterly revenue exceeded RMB 100 million mark, a historical first since we transitioned to the pure SaaS business model. Third, our core developer subscription business achieved a record of RMB 61.9 million in revenue this quarter, breaking through the RMB 60 million threshold for the first time. Our flagship product, EngageLab, continues to shine. Our EngageLab business reached another very important key milestone, ARR of USD 10 million in December 2025. This represents a stunning 186% of year-over-year growth. Number five, gross profit grew significantly at 23% year-over-year and the highest it has been for the past 16 quarters. Number six, operating activities brought in a net cash flow of RMB 35.1 million. Our net dollar retention, NDR, for core developer service surpassed 100%, reaching 103%. The 2025 numbers demonstrate our excellent execution. We have exceeded most, if not all, of our targets. With this in mind, Chris and I believe we are exceptionally well positioned to continue this momentum into 2026. Now let's turn to the business outlook. Based on the current available information, the company sees the 2026 full year revenue guidance to be in the range of RMB 450 million to RMB 480 million, representing a very solid and strong growth of 20% to 28% year-over-year compared to 2025. And the above outlook is based on current market conditions and reflects the company's current and preliminary estimate of the market and operating conditions and the customer demand, which are all subject to change. Lastly, before I conclude, I'll give a quick update on the share repurchase plan. In this quarter ended December 31, 2025, we repurchased 73,000 ADSs. Cumulatively, we have repurchased a total of 400,000 ADS since the start of our repurchase program. And this concludes our prepared remarks. We're happy to take your questions now.
