Now moving on to our business, product and technology update for the quarter. Let's start with Agora. In this quarter, we held a series of webinars to discuss how real-time engagement, which combined with state-of-art technologies and artificial intelligence and AR/VR can greatly influence or even transform various industries, including live shopping, telehealth, and Internet of Things. For example, in live shopping, we see more and more digital brands and platforms relying on interactive live streaming to redefine the way consumers make their buying decisions. By creating a personalized, social and engaging experience for the audience, a loyal community of repeated buyers will strive and help drive sales. The combination of RTE AI and AR/VR is driving a rapid revolution of IoT use cases.

For example, heavy machinery operators can work remotely with an enhanced wheel that feeds beyond blind spots, enabling them to corral challenging tasks in a safe and efficient manner. For autonomous driving -- autonomous vehicles or AI powered robotic, human operators can monitor their operations from remote locations and pick a world whenever necessary. This series of webinars was well received and attracted thousands of participants globally. Mainly, Agora is uniquely positioned to facilitate innovation in this industry by leveraging our cutting-edge RTE technology and deep understanding of industry specific use cases. In this quarter, we also released a brand-new beta word of our cumulative product, which provides real-time data synchronization and low latency event notifications between devices and servers.

The new version can now accommodate an unlimited number of users per channel, deliver better synchronization, support storage and manage conflicting message effectively. It enables a wide range of use cases such as real-time bidding in live shopping, virtual gifting in live streaming, player status synchronization in online gaming, live pooling in education and remote command of IoT devices. In December, Twilio announced the upcoming End of Life of its Programmable Video Product, which was a competing solution with our video calling product. We have pushed a series of blogs covering guidance and best practice for migrating from Twilio to Agora, of course, a major operating system and developer platforms. Additionally, we are offering up to two months free to customers who switch from Twilio.

We believe Agora is an ideal alternative for Twilio's video customer base and expect to enhance our global market share following Twilio's exit. We are also thrilled to see OpenAI's recent launch of Sora, a powerful AI model that can create realistic and imaginative video clips based on task instruction. It aligns with our early view that multimodal capabilities of generative AI models will advance rapidly, eventually enabling human users to directly interact with AI models in voice and video format. This technology breakthrough in AI will greatly expand the boundary of real-time engagement and bring about tremendous new possibilities. I believe Agora is well positioned to play a critical role in facilitating massive games transmission between AI models and human users.

Moving on to Shengwang. Following the availability of Apple Vision Pro earlier this month, we have enabled many customers to launch applications in the Vision Pro App Store. I personally used Vision Pro, and I believe, it marks an important breakthrough in XR technology. The high-value resolution and the see-through capability of Vision Pro demand higher quality video content and opens the possibility for hologram video content consumption and interactions. For example, people will be able to watch a live keynote speech in hologram format on Vision Pro. Our network is well positioned to power such content and interaction. Over the past few months, mini games that overlay on video live streaming have been gaining popularity among social platforms.

For example, a round out of Ludo can serve as icebreaker in a matchmaking room. Live streaming channels can import team-based mini games where audience can participate by sending putting chats and gifts. We have partners with leading mini game developers to offer our customers a wide range of mini games that can be easily embedded into their applications. Early data from our customers shows that the mini game integration has resulted in increased user penetration, longer session duration and more monetized opportunities. In this quarter, we also introduced virtual sound card, an advanced feature that simulates key components of a professional hardware sound card, such as exciter, compressor, equalizer and reverberator to products end users' voice in real time.

Users can now easily enhance and modify their voices with only a cellphone without the need to purchase a computer with a professional sound card. For example, a customer recently add virtual sound card in their online IoT rooms. Users can choose from a range of pre-set specifics to make their voices clearer, sweeter, [indiscernible] or more mature. Slightly off-key notes can also be adjusted automatically. This capability makes users more confident to participate therefore, boosting user engagement and stickiness on our customers' platform. Before concluding my prepared remarks, I would like to thank both the Agora and Shengwang team for their commitment and diligence during this challenging period. We not only delivered consecutive quarter-over-quarter top line growth since the second quarter, but also achieved non-GAAP probability in the fourth quarter.

Looking ahead at 2024, we will keep focusing on creating customer value and enhancing our competitive advantage with the goal of expanding our market share globally. With that, let me turn things over to Jingbo, who will review our financial results.

Jingbo Wang: Thank you, Tony. Hello, everyone. Let me start by first reviewing financial results for the fourth quarter of 2023. And then I will discuss outlook for the first quarter to 2024. Total revenues were $36 million in the fourth quarter, an increase of 2.9% quarter-over-quarter and a decrease of 10.2% year-on-year. Agora's revenues were $15.3 million in the fourth quarter, flat compared to last quarter and decreased 3.2% year-over-year. The year-over-year decrease was primarily due to reduced usage from customers in emerging markets due to a challenging macroeconomic environment and tightening financing conditions starting from the second half of 2022. Shengwang revenues were RMB 148.7 million in the fourth quarter, an increase of 5% quarter-over-quarter and a decrease of 9.6% year-over-year excluding revenues from the of the disposed CEC business.

The quarter-over-quarter increase was primarily due to an increase in revenues to digital transformation customers for large enterprises. The year-over-year decrease was primarily due to slowing demand from internet customers due to regulation and general economic conditions. Dollar-based net retention rate is 93% for Agora and 82% for Shengwang, excluding revenues from discontinued business. Moving on to cost and expenses. For my following comments, I will focus on non-GAAP adjusted financial measures, which excludes share-based compensation expenses, acquisition-related expenses, financing-related expenses, amortization expenses of acquired intangible assets, income tax related to acquired intangible assets, impairment of goodwill, depreciation of property and equipment, and amortization of land use rights.

Adjusted gross margin for the fourth quarter was 65.2%, which was 0.3% higher than Q4 2023 and 1.7% lower in Q3 2023. The year-over-year increase was mainly due to the change in product mix and the implementation of technical and infrastructural optimization. The quarter-over-quarter decrease was mainly due to an increase in on-premises solution, revenue which has a lower gross margin. As we continue to implement effective expense controls, our adjusted R&D expenses decreased 18% year-over-year to $13.7 million in Q4. Adjusted R&D expenses represented 38% of total revenues in the quarter, compared to 41.6% in Q4 last year. Adjusted sales and marketing expenses were $6.3 million in Q4, decreased 40.6% year-over-year. Sales and marketing expenses represented 17.5% of total revenue in the quarter compared to 26.4% in Q4 last year.

Adjusted G&A expenses were $5.8 million in Q4, decreased 20.5% year-over-year. G&A expenses represented 16% of total revenues in the quarter compared to 18.2% in Q4 last year. Adjusted EBITDA was negative $2 million translating to a 5.6% adjusted EBITDA loss margin fourth quarter, significantly lower than the adjusted EBITDA loss margin of 21.1% in Q4 last year. Non-GAAP net income was $1.4 million in Q4, translating to a 3.9% net income margin for the quarter compared to a non-GAAP net loss margin of 39.3% in Q4 last year. As Tony just mentioned, thanks to our effective cost controls and relentless drive for revenue growth, we achieved profitability on a non-GAAP basis for the first time in more than three years. This demonstrates the resilience of our business amid a very challenging operating environment as well as our continued discipline and efforts in optimizing our cost structure.

Now turning to cash flow. Operating cash flow was positive $3.7 million in Q4 compared to negative $4.6 million last year. Free cash flow was positive $3.4 million compared to negative $6.1 million last year. Moving on the balance sheet. We ended Q4 with $371.8 million in cash, cash equivalents and deposits and financial products issued by banks or $4.03 per ADS. Net cash outflow in the quarter was mainly due to share repurchase of $10.1 million, which was offset in part by a free cash flow of $3.6 million. Since the Board approved our share repurchase program in February 2022 and as of December 31, 2023, we had returned approximately were $104.3 million to our shareholders through share repurchases, reducing our share count by roughly 18%.

So far, we have completed 52% of $200 million share repurchase program. We are pleased to announce that our Board has also authorized another 12-month extension of a $200 million share repurchase program through end of February next year with all other terms unchanged, which is a vote of confidence on financial strength and long-term prospects of the business. Now turning to guidance. There's a Seasonal impact, especially reduced usage in certain regions. During Lunar New Year for the first quarter of 2024, we currently expect total revenues to be between $32 million and $34 million. This forecast reflects our current and preliminary views on the market and operational conditions, which are subject to change. In closing, we are very proud of our execution and strong financial results during this challenging period.

Turning to profitability is a remarkable milestone. Thank you to both Agora and Shengwang teams for their hard work and sacrifice in the past quarter. Thank you, everyone, for attending the call today. Let's open it up for questions.
