Hello everyone, and thank you and welcome to Kingsoft Cloud fourth quarter and fiscal year 2025 earnings call. I am Tao Zou, CEO of Kingsoft Cloud. Since the beginning of 2025, the global AI industry has reached a series of milestones, from the democratization sparked by the DeepSeek moment to the active competition among multimodal large models. From the leap of embodied AI into the physical world to agents close to the capability of understanding and execution. AI is evolving with unstoppable momentum, linking across models, agents, computing power to industrial applications, reshaping every sector. As a tightly integrated component of the AI five-layer stack, cloud computing is now meeting an unprecedented surge in demand for intelligent computing. This year, we stayed committed to our high quality and sustainable development strategy. Embracing the opportunities in AI era, strengthening our capability through solid execution.
We have delivered impressive results, achieving strong financial performance while forging lasting business strength. First, we recorded a historical high quarterly revenue, reaching RMB 2.76 billion, representing a year-over-year growth of 24%. Among which revenues from Public Cloud Services increased by 35% to RMB 1.9 billion. Our intelligent computing services keep driving our growth. The gross billing of AI business reached RMB 926 million, representing a 95% year-over-year and contributing 49% of our Public Cloud Services.

Now, I would like to walk you through the key business highlights for the fourth quarter of 2025. In terms of Public Cloud Services, revenue reached RMB 1.9 billion this quarter, representing a year-over-year increase of 35%. From customer perspective, in 2025, AI continued pushing its boundaries, driving industries to fully embrace it, diversifying our customer base. Beyond leading AI enterprises and internet giants, we now also serve automotive manufacturing, autonomous driving, embodied AI, and fintech sectors, et cetera. We've solidified our cooperation within the Xiaomi and Kingsoft ecosystem while capturing new external opportunities. From product and services perspective, we keep pushing the limits of cluster scale, supporting large-scale training and explosive inference demand. Notably in this quarter, we delivered a new inference cluster for top video streaming platform, serving over 100 million users.
We also secured a major fintech customer using our token-based inference service, who speak highly of our stable model and computing power services. On supply chain front, despite market uncertainties, our well-established and resilient supply chain, built through years of experience, allowed us to plan ahead strategically and stock key components dynamically to ensure sustainable business growth. Now in terms of Enterprise Cloud, revenue reached RMB 859 million this quarter, a significant quarter-over-quarter increase of 18%. Driven by the AI Plus policy, industrial intelligence solutions have become a key growth driver. The demand for specialized vertical models, real-world application, and strict data compliance makes cloud services more essential than ever in advancing industrial intelligence.
The AI business of Enterprise Cloud is paving the way for steady long-term growth, not only representing a trillion-dollar market opportunity, but also playing a critical role in driving the technological leap across industries. As a B2B cloud service provider with solid technology, expertise, and enterprise service capabilities, we are well-positioned to capture these industrial transformation opportunities. In the area of enterprise services, we achieved key breakthroughs in high-end manufacturing industry. We provided stable and high-performance computing service to the top enterprises to support their process in intelligent manufacturing, industrial vision, and AI R&D. In healthcare space, we launched a Data Agent-based AI application in healthcare intelligent operation process, marking a paradigm shift from digitalization to intelligence. This analysis through natural dialogues platform enables natural language insights into DRG cost control, moving hospital management from retrospective statistics to proactive intervention.
While significantly lowering the barriers to data application, we have further solidified our technical moats and differentiated competitive advantages in high-value medical AI scenarios. In public services area, we partnered with telecom operators to provide sustainable and stable high-performance computing cluster for the public services sector, successfully entering key markets like Shanghai. We believe that by leveraging Kingsoft Cloud's deep vertical expertise and enterprise service experience, intelligent computing opportunities in the Enterprise Cloud segment represent a massive industrial frontier, generating synergies with our public cloud business. In terms of products and technology, we are building a next-generation computing services system for LLM training, inference, and industrial intelligence, offering full-stack capabilities from computing services to model-as-a-service. Our technology upgrades from basic cloud computing to an AI-first, AI-native cloud architecture, contributing toward digital and intelligent transformation across sectors.
We focus on the technologies catering to model training and inference scenarios, aiming to provide highly stable, highly efficient, and ready-to-use intelligent computing services. This quarter, our StarFlow Platform keeps upgrading with the launch of MCP, aka Model Context Protocol Hub, prompt optimization, and AI search features to help enterprises develop and deploy AI agents through a unified platform, gradually building a new ecosystem centered around agent-based operations. For enterprises with private deployment demands, our Galaxy Stack provides heterogeneous GPU management, RoCE network, and intelligent container scheduling capabilities. We also feature full-stack localization with indigenous adaptations to empower intelligent transformation across verticals. Standing at a new starting point, looking ahead, we're truly excited by the limitless possibilities that lie before us. We will remain committed to our high-quality and sustainable development strategy.
By embracing the immense opportunities presented by the AI era, developing along with the industry, and refining our core technologies, we will continue to capture the market opportunities both within and beyond our ecosystem, optimizing the operations of our assets to enhance profitability and thereby create value for our customers, shareholders, employees, and society. I will now pass the call to our CFO, Ms. Yi Li, to go over our financials for the fourth quarter and fiscal year 2025. Thank you.
Thank you, Mr. Zhou and Clark, and thank you all for joining the call today. Before we walk through the details of financial results for the fourth quarter and fiscal year 2025, I would like to highlight the following aspects. First, our revenue has achieved record high RMB 2,761 million this quarter, representing a year-over-year growth rate of 24%. Within that, revenue from Public Cloud Services was RMB 1,902 million, increased by 35% from RMB 1,410 million in the same quarter last year. Unprecedented explosive demand for AI business drove a 95% year-over-year billing growth, which totaled RMB 926 million. Second, profitability has seen substantial improvement. Driven by shifts in our revenue structure, our adjusted gross margin continued its upward trend, rising to 70% from 60% in the previous quarter.
Adjusted EBITDA margin reached 28%, up 12 percentage points from 60% in the same quarter last year, though down from 33% last quarter. The year-over-year growth was fueled by a large contribution from AI-related business. Well, depreciation represent the primary cost component. The sequential decrease was mainly due to a non-recurring subsidy received last quarter, which established a high baseline. Notably, we have achieved adjusted operating profits for two consecutive quarters, reaching RMB 55 million this quarter, which was a 2% margin. This result validates our ability to monetize intelligent cloud opportunities and our strategic focus on high-quality enterprise services. Third, our cash and cash equivalent achieved RMB 6,080 million, strengthening our ability to further support the investment into AI business. Now, I will walk you through our financial results for the fourth quarter of 2025.
This quarter, total revenue was RMB 2,761 million. Of these, revenues from Public Cloud Services were RMB 1,902 million, up 35% from RMB 1,410 million in the same quarter last year. Revenues from Enterprise Cloud Services reached RMB 859 million during this seasonally strong quarter, which was characterized by a high volume of project completion. Total cost of revenues was RMB 2,296 million, up 27% year-over-year, which was mainly due to our investment into infrastructure to support intelligent cloud business growth. IDC costs increased by 13% year-over-year from RMB 725 million to RMB 812 million this quarter. The increase was mainly due to the increasing needs of racks, which serves the expanding AI business.
Depreciation and amortization costs increased from RMB 323 million in the same quarter of 2024 to RMB 741 million this quarter. The increase was mainly due to the depreciation of newly acquired and leased servers and network equipment, which were mainly allocated to our AI business. Solution development and service costs increased by 50% year-over-year from RMB 557 million in the same quarter of 2024 to RMB 642 million this quarter. The increase was mainly due to the solution personnel expansion. Fulfillment costs and other costs were RMB 40 million and RMB 61 million this quarter. Our adjusted gross margin for the quarter were RMB 471 million, increased to 10% year-over-year, and 20% quarter-over-quarter.
It was mainly due to the expansion of our revenue scale, the enlarged contribution from AI business, and the cost control over IDC racks and servers. Adjusted gross margin increased from 60% last quarter to 70% in this quarter, which was mainly due to the high contribution from Enterprise Cloud. On the expense side, excluding share-based compensation costs, our total adjusted operating expenses were RMB 459 million, increased by 3% year-over-year and increased 9% quarter-over-quarter. Of which, our adjusted research and development expenses were RMB 181 million, increased by 7% from same quarter last year.

Our adjusted operating profit was RMB 55 million, increased by 124% from adjusted operating profit of RMB 24 million in the same period last year. The improvement was mainly due to the expansion of our revenue scale and gross profit, as well as the expense control. The total expense as a percentage of revenue keeps decreasing. Adjusted operating profit margin increased from 1% in the same period last year to 2% this quarter. Our non-GAAP EBITDA was RMB 785 million, increased by 180% from RMB 360 million in the same quarter last year. Our non-GAAP EBITDA margin achieved 28% compared with 6% in the same quarter last year. It was mainly due to our strong commitment to AI cloud computing development, strategic adjustment of business structure, strict control over costs and expenses.
This quarter, our capital expenditure, including those financed by third parties and right of use assets of RMB 10 and RMB 20 for finance lease liabilities, were RMB 496 million. For the full year 2025, our total revenue achieved RMB 9,759 million, increased by 23% from RMB 7,785 million in 2024. Among which, revenues from Public Cloud Services were RMB 6,634 million, increased by 33% year-over-year. Revenues from Enterprise Cloud Services were RMB 2,925 million.
Increased by 5% year-over-year. Adjusted gross profit was RMB 1,542 million, increased by 40% from RMB 1,358 million last year.

We remain focused on AI-driven strategy, providing customers with high value-added cloud services. That's all for the introduction of our operational and financial results. Thank you all.
Thank you. Operator, this concludes our prepared part, my remarks. We are now happy to take your question. Please ask your question in both Chinese and English if possible. Operator, please go ahead. Thank you.
Thank you. As a reminder, to ask a question, you will need to press star one and one on your telephone and wait for your name to be announced. To withdraw your question, press star one and one again. We'll now move on to our first question. Our first question comes from the line of Liping Zhao from CICC. Please go ahead. Your line is open.
[Non-English content] Good evening, Mr. Zhou and Ms. Li. Thanks for taking my questions and congrats for the very good 4Q results. I have two questions here.
First, Xiaomi recently launched the MiMo- V2 series models, which have received positive market feedback. How should we view our role and the positioning within Xiaomi's AI strategy? What strategies will be implemented around Xiaomi and Kingsoft service going forward? Secondly, how does the management view the current pricing uptrend in the cloud service industry? Has the company already adjusted its prices for AI computing services? Or are there any related plans in place? To what extent are those price adjustments driven by demand or driven by the upstream procurement cost pass through? Thank you.

OK, the answer comes from our CEO. A little bit of the background back in 2024. I think that was in August. We had an internal discussion about around the development of AI and models for the whole Xiaomi and Kingsoft ecosystem. The idea was that the whole Xiaomi and Kingsoft ecosystem will form a team or portfolio of solutions where a whole system where Kingsoft will stay discipline and not really developing our own large language models, which is left to for Xiaomi to develop. The MiMo model and its widely recognized performance is actually an implementation and manifestation of our overall AI strategy within the Xiaomi and Kingsoft ecosystem. Secondly, back in 2025. One year later from the internal discussion session, from a KC perspective, we formed a strategy that's called a 1+N.
The one here actually refers to the Xiaomi MiMo model, which is the key to KC's inference strategy. In the future, we will continue to adhere to this strategy, which essentially means that within the ecosystem, we will continue to serve the Xiaomi and Kingsoft ecosystem. For external customers, we will also try to monetize our model as a service capabilities thereby not only in the training area that we are able to make a revenue and profits, but also make our contribution in the inference era that is approaching. Thank you.
[Non-English content]
The answer comes from our SVP Mr. Liu Tao. A little background again. In the Q3 last year, we have anticipated the significant price increase from the supply chain side. Therefore we had dynamically and strategically stocked up some of the key components. We were actually prepared for this, what's unfolding today. Now in terms of the price hike that you were asking. We stick to two principles. Number one, if we already for the, for some of the customers and business where we already have contracts in place and where we have the stocking of the underlying resources, we tend to not increase the pricing. However, for some of the new customers, new contracts, especially with significant increase of usage, there is going to be significant price hiking in this kind of scenarios. Now, also in terms of profitability, one thing is that we will actually try to pass through some of the upstream cost increases to our customers. Secondly, we also, depending on the demand right, we also try to increase some of the price to reflect and increase our profit. Thank you.
Operator, next question please.
Thank you. Please stand by. Our next question comes from the line of Wenting Yu from CLSA. Please go ahead, your line is open.
[Non-English content] The first question is that some of our pure cloud service partners have announced they will shift their cloud business more towards an approach from the traditional server rental and also the subscription model. Will KC adopt a similar strategy?
How do you view the impact of this trend on industry competition and long term profit margin? The second question is regarding the impact from the ByteDance's Volcano Engine. It is adopting a relatively low price strategy. How do you view the impact on the industry and also on potentially our business this year? Thank you.

Okay. Regarding your question on the shifting to model as a service strategy. We have noted some of the other peer companies who released their results earlier than us mentioning this. However, my view is that this is not actually some new concept. It is actually one of the inevitable stage of the development of AI as well as large language model. From the training that we do to create them to a certain phase that they become applicable and workable in our day-to-day work and life. In relation to our own inference related work model to service work, we actually launched the StarFlow Platform as we mentioned in the prepared remarks last year.
Because we are a neutral platform, we were able to host essentially all of the open source models, including also the model coming from Xiaomi to provide model as a service business. This is essentially actually the fastest growing business in the history of the company. Actually, we talked about the Xiaomi MiMo model earlier. The way that we're providing services for Xiaomi MiMo model is also model as a service business. Also, for some of the large language model customers that we used to and we're still providing training services to them, we also provide model as a service business to them as well to cater to their inference needs.
Now to the second question about the price change for Volcano Engine. I haven't really, you know, noticed that particular piece of news. However, the general market dynamics today is that on one hand we're seeing explosive growth on the demand side, and we're seeing a particularly high price hiking from the supply chain side. I do not personally think that under such circumstances changing price to a lower level would actually be implementable and applicable in the real world. Now what I have focused more is the price hiking information from for example Alibaba Cloud. We have worked with them together.
We have been in the industry together for many years, and this is the first time that we've seen them hiking their price. Also an addition from our SVP, Mr. Liu Tao, is that there is a difference between the catalog price and the actual price that the companies that we as cloud players and our customers engage into. The change in catalog price is more of a marketing kind of purpose. It does not necessarily mean the actual price that companies enter into business with. Thank you.
Thank you. Our next question comes from the line of Timothy Zhao from Goldman Sachs. Please go ahead. Your line is open.
[Non-English content]
Thank you, Matthew, for taking my question. My first question is on your financial outlook. Just wondering if you can share some color on how we should think about the revenue EBITDA operating profit growth outlook for this year. Also on the capital expenditure plan, what is your thoughts and concerns of balance sheet and also the prepayment from certain customers? Do you think it's possible to further raise your CapEx plan given the rising AI demand? Secondly is regarding the third party revenue in the AI outlook. Just wondering if you can share more detailed color on what specific product or what type of customers are driving this third party AI growth.
What is the breakdown and outlook between the mix of AI training versus AI inferences? Thank you.
All right. I will take the CapEx first. For 2026, we expect total CapEx and tangible assets to exceed RMB 10 billion, represent expansion from 2025 level. From the structure, we expect approximately half our CapEx is targeted to be covered by customer prepayment arrangements, which will significantly reduce our funding requirements. Additionally, we plan to access more assets through short and long-term leases, with payment structure as operating cash flows to minimize upfront capital, commitments. For the funding position and financing needs, we currently have no equity finance plans. 2026 capital expenditure are secured through four channels. First, proceeds from our 2025 financing. Second are customer operating receipts. Third, the strategic customer prepayments. Fourth, the committed credit facilities from banks and financial lease institutions.
Incremental resource requirements will be made primarily through leasing to preserve balance sheet flexibility. For the guidance for the 2026, we expect our growth rate will accelerating and the EBITDA rate will improve much better in 2026 as well.
If you look at the past results, as discussed in the prepared remarks, for the top five non-ecosystem customers combined revenue, for year-over-year basis, revenue growth was 44%, which is very really strong growth. Those would include internet companies, autonomous driving, and robotics. In terms of looking forward into the year of 2026, we do see extremely large demand coming from outside of the ecosystems. To some extent that such demand is actually higher than the demand from our ecosystem. The final revenue or financial results coming from that demand will actually be dependent on how much resources we're able to secure and to deliver to such customers.
Now, from the perspective of products and solutions, we're actually seeing more than half of the potential demand coming in for inference versus training. For the StarFlow platform, which we discussed earlier, it's growing really fast for that business. We're seeing better profit margin coming from that particular business. This is a result of course from the very good application and increasing penetration for agents and cloud applications. Thank you.
Thank you. Due to time constraints, this concludes our Q&A session. Thank you once again for joining us today. If you have any other questions, please feel free to contact us. Look forward to speaking with you again next quarter. Have a nice day. Thank you all.
This concludes today's conference call. Thank you for participating. You may now disconnect. Speakers, please standby.
