Agora closed 2025 with its fifth straight quarter of GAAP profitability and its first full year of GAAP profitability since 2018, reporting Q4 revenue of $38.2 million (up 10.7% year-over-year, above guidance) and net income of $4.9 million at a 12.9% margin. The overseas Agora division led growth at 14.4%, highlighted by hosting the largest US live video-shopping event in history for MrBeast on Whatnot at roughly 600,000 peak concurrent viewers. Gross margin eased to 65.1% as subscale conversational-AI products weighed on mix, while operating cash flow doubled to $9.3 million and the board extended the $200 million buyback to February 2027. Management guided Q1 2026 revenue to $36-37 million and set a goal of GAAP operating profit in Q4 2026, absorbing roughly $6 million of stock comp and $4 million of headquarters amortization along the way.
Thanks, operator. Welcome everyone to our earnings call. I'll begin by reviewing our operational performance for the past quarter. We're pleased to report our fifth consecutive quarter of GAAP profitability in Q4, marking our first full year of GAAP profitability since 2018, driven by sustained double-digit revenue growth, improved operating leverage, and disciplined cost management. Total revenue for the fourth quarter were $38.2 million, representing 10.7% year-over-year growth. Our GAAP net profit for the quarter was $4.9 million, with a GAAP net margin of 12.9%. I would like to share with you our recent business update, which highlights both the strength of our core real-time engagement business and the accelerating momentum of our conversational AI initiatives.
Our platform scalability and reliability were recently validated during a high-profile live streaming event over the Super Bowl weekend. MrBeast, the world most-followed content creator, hosted a forecast session on Whatnot the leading video-based shopping platform and a long-standing customer of Agora. We delivered high-quality full HD video to nearly 600,000 peak concurrent viewers worldwide while enabling their interactions at sub-second latency. To quote our customer's own word from their technical blog, "On event day, Agora's real-time media pipeline performed reliably at peak. Time to first stream stayed under one second. Latency remained consistently low, and video quality held stable throughout the stream, even as we pushed systems to their limits at extreme load." We believe this is the largest live video shopping event in U.S. history. Events of this magnitude are the ultimate stress test for real-time infrastructure.
Our ability to deliver stable, high-quality video with ultra-low latency at a global scale demonstrates our leadership in network resilience, distributed architecture, and real-time routing. This event was powered exclusively by our platform, as no competitors can match our performance and the scale. This is why industry leaders in e-commerce, social entertainment, and education continue to trust our infrastructure for their most critical moments. At the same time, we are witnessing rapid adoption of our Conversational AI Engine product. Since its launch in March 2025, usage has more than doubled each quarter. We are also encouraged to see, you know, early experimentations among our customers quickly evolve into real-world deployment across multiple verticals, including customer service, smart devices, education, and AI-powered consumer applications.
Companionship toys powered by our solution, such as Fuzozo, are driving accelerated shipment with high user stickiness. Validating this momentum, a leading consumer hardware giant recently launched a companionship toy built on our technology. Furthermore, our Conversational AI Device Kit, integrating a voice module and an emotion display screen, has set an industry trend and is now widely adopted by manufacturers. We started the year with a strong reception of our conversational AI solution for physical AI at CES 2026 in January. At the event, we introduced the latest upgrade of our Conversational AI Device Kit, featuring enhanced multimodal capabilities, including vision understanding and motion control. These new capabilities enables the development of embodied AI hardware and robotics across multiple use cases.
For example, our customer, Luwu Dynamics, is developing a desktop embodied AI robot powered by this solution. Many of our customers also showcased products at CES that leverage our solutions, ranging from AI companion devices and robotics to next-generation physical AI products. The strong market interest and media coverage coming out of CES further validates the growing demand for real-time human-like re-interaction embedded directly into smart devices. Beyond one-on-one interaction between humans and AI agents, we're also expanding into module agent collaboration scenarios. During the quarter, we supported Agnes AI in launching its next-generation AI group chat and multi-agent collaboration platform. By leveraging our real-time engagement infrastructure and conversational AI capabilities, Agnes AI enables multiple AI agents and human participants to interact seamlessly. We believe multiple agent observation represents the next frontier of AI-driven productivity.
While agent can coordinate tasks, share information, and collaborate with humans in real time. This development, a clear theme is emerging. As AI becomes more interactive and multimodal, the technology complexity behind delivering a seamless interaction experience between a human and an AI agent increases significantly. Real-time conversational AI requires not only powerful foundation models, but also advanced audio processing, ultra-low latency networking, global scalability, interruption handling, turn-taking management, and device-level optimization. These are areas where we have made substantial investments and have built a strong competitive edge. Our deep expertise in real-time infrastructure uniquely positions us to bridge the gap between AI model capabilities and production-grade user experiences. Looking ahead, we remain focused on driving revenue growth and advancing conversational AI innovation throughout 2026.
We enter the new year with strong momentum, supported by an expanding customer pipeline, growing production deployments, and increasing ecosystem partnership. We believe we are well-positioned to capture this transformation and create long-term value for our shareholders. Before I conclude, I would like to thank our customers, developers, partners, and shareholders for their continued trust and support. Our global team for their dedication and innovation. With that, let me turn things over to Jingbo, who will reveal our financial results.
Thank you, Tony. Hello, everyone. Let me start by first reviewing financial results for the fourth quarter of 2025, and then I will discuss outlook for the first quarter of 2026. Total revenues for the fourth quarter reached $38.2 million, representing a 10.7% year-over-year increase and exceeding the high end of our revenue guidance. This marks our fourth consecutive quarter of double-digit organic growth. If we look at the two business divisions, Agora revenues reached $19.9 million in Q4, representing 14.4% year-over-year growth and 9.3% quarter-over-quarter growth. The strong growth reflects our successful market penetration and growing adoption in verticals such as live shopping.
Shengwang revenues reached RMB 129.2 million in Q4, up 5.7% year-over-year and 5.6% sequentially, driven by continued business expansion and adoption in key verticals such as social, entertainment, and IoT. Dollar-based net retention rate is 109% for Agora and 89% for Shengwang. Gross margin for this quarter was 65.1%, down 1.5 percentage points year-over-year, and 0.9 percentage points sequentially. The slight decline was primarily driven by the lower margin profile of our conversational AI-related products, as usage is still ramping up and remains at a sub-scale level. Turning to expenses, R&D expenses were $13.6 million in Q4, down 7.7% year-over-year, reflecting our continued cost discipline.
R&D expenses accounted for 35.8% of total revenues, compared to 42.9% in the same period last year. The marketing expenses were $7.1 million in Q4, down to 0.1% year-over-year. The marketing expenses represented 18.7% of total revenue in the quarter, compared to 21.1% in Q4 last year. G&A expenses were $5.4 million in Q4, a decrease of 16.5% year-over-year. Primarily due to lower provisions for credit losses following improved customer collections. G&A expenses represented 14.1% of total revenues compared to 18.7% in Q4 last year. Moving on to the bottom line. We delivered net income of $4.9 million in Q4, representing a 12.9% net income margin.
As Tony just mentioned, this marks our fifth consecutive quarter of GAAP profitability and the first full year of GAAP profitability since 2018. Based on current business momentum and visibility into 2026, we expect net income to grow compared to 2025. Turning to cash flow. Operating cash flow was $9.3 million in Q4 compared to $4.5 million in last year, in Q4 last year. Moving on to balance sheet. We ended Q4 with $374.9 million in cash equivalents, bank deposits, and financial products issued by banks. Net cash outflow in the quarter was mainly due to share repurchase of $10.9 million.
In the fourth quarter, we repurchased 12 million ordinary shares or 3 million ADSs, representing 3.3% of our outstanding shares at the beginning of the quarter. Since our board approved the share repurchase program in February 2022, we have repurchased $143.1 million worth of shares through December 31st, 2025, which represented 71.6% of our $200 million share repurchase program. We are pleased to announce that our board has authorized a 12-month extension of our share repurchase program through February 28th, 2027, with all other terms unchanged. This reflects the board's confidence in our long-term growth prospects and our continued commitment to delivering shareholder value. Turning to guidance.
For the first quarter of 2026, we currently expect total revenues to be between $36 million and $37 million compared to $33.3 million in the first quarter of 2025, representing year-over-year growth rate of 8.1%-11.1%. This outlook reflects our current and preliminary views on the market and operational conditions, which are subject to change. In closing, I want to extend my sincere gratitude to our exceptional teams in Shengwang and Agora. Our sustained double-digit revenue growth and double-digit net income margin are a direct result of their dedication and execution. Let's remain focused on driving revenue growth and advancing conversational AI innovation throughout 2026. To our shareholders, thank you for your continued trust and partnership. Thank you all for joining the call today. Let's open it up for questions.
