Kingsoft Cloud Announces UnauditedFirst Quarter 2026 Financial Results

Kingsoft Cloud Holdings Limited (“Kingsoft Cloud” or the “Company”) (NASDAQ: KC and HKEX: 3896), a leading cloud service provider in China, today announced its unaudited financial results for the first quarter ended March 31, 2026.

Mr. Tao Zou, Chairman of the Board and Chief Executive Officer of Kingsoft Cloud, commented: “We continued to advance our 'High Quality and Sustainable Development Strategy'. The gross billing of AI business grew 90% year-over-year, accounting for more than half of the revenue from public cloud services for the first time. We are excited about the vast opportunities in this new era, from computing power to vertical solutions, as we continued to invest in infrastructure, enhance our capabilities, and strengthen customer base both within and outside of the ecosystem.”

Ms. Yi Li, Chief Financial Officer of Kingsoft Cloud, added, “We delivered a solid quarter, with our total revenue reaching RMB2,703.7 million, an increase of 37.2% year-over-year. Our adjusted gross profit was RMB351.4 million, increased by 7.2% year-over-year, despite overall supply chain challenges. Our adjusted EBITDA margin was 27.6%, increased by 11.4 percentage points year-over-year, in line with our AI revenue growth. In light of strong demand across diverse sectors, we remain steadfast in investing in our infrastructure, as our capital expenditures and leased assets obtained in combination amounted to RMB3 billion in Q1, and we expect to continue to invest to facilitate further business expansion throughout the year.”

First Quarter 2026 FinancialResults

Total Revenues reached RMB2,703.7 million (US$392.0^1^ million), increased by 37.2% year-over-year from RMB1,970.0 million in the same quarter of 2025, and decreased by 2.1% quarter-over-quarter from RMB2,761.4 million in the fourth quarter of 2025. The year-over-year increase was mainly due to the revenue growth from Xiaomi and Kingsoft Ecosystem and AI related customers and our further penetration into enterprise cloud customers. The quarter-over-quarter decrease was mainly due to the seasonality impact for enterprise cloud.

Revenues from public cloud services were RMB1,996.3 million (US$289.4 million), increased by 47.5% year-over-year from RMB1,353.5 million in the same quarter of 2025 and increased by 4.9% quarter-over-quarter from RMB1,902.4 million last quarter. The increase was mainly due to higher overall revenue driven by the growth of AI demands.

Revenues from enterprise cloud services were RMB707.4 million (US$102.6 million), representing a year-over-year increase of 14.7% from RMB616.5 million in the same quarter of 2025 and a quarter-over-quarter decrease of 17.6% from RMB859.0 million last quarter. The sequential decrease was mainly due to the Chinese New Year impact and differentiated delivery schedules for various projects.

Unless otherwise noted, the translation of RMB into US$ has been made at RMB6.8980 to US$1.00, the noon buying rate in effect on March 31, 2026 as certified for customs purposes by the Federal Reserve Bank of New York.

Cost of revenues was RMB2,358.0 million (US$341.8 million), representing an increase of 42.8% from RMB1,651.7 million in the same quarter of 2025, which was mainly due to our investment into AI computing resources. IDC costs increased by 26.1% year-over-year from RMB722.8 million to RMB911.1 million (US$132.1 million) this quarter, largely in line with our revenue expansion. Depreciation and amortization costs increased from RMB378.5 million in the same quarter of 2025 to RMB818.9 million (US$118.7 million) this quarter. The increase was mainly due to the depreciation of newly acquired and leased servers, and network equipment which were mainly related to AI business. Solution development and services costs increased by 13.8% year-over-year from RMB505.2 million in the same quarter of 2025 to RMB574.8 million (US$83.3 million) this quarter. The increase was mainly due to the solution personnel expansion of Camelot. Fulfillment costs and other costs were RMB1.8 million (US$0.3 million) and RMB51.4 million (US$7.4 million) this quarter.

Gross profit was RMB345.7 million (US$50.1 million), representing an increase of 8.6% from RMB318.3 million in the same quarter of 2025. The increase was mainly due to the expansion of our revenue scale, especially the AI business. Gross margin was 12.8% in this quarter, compared with 16.2% in the same quarter of 2025 and 16.9% in the fourth quarter last year. The decrease was mainly due to the higher cost of servers along with the expansion of AI business, as well as upfront costs incurred for future revenue-generating activities with certain customers. Non-GAAP gross profit^2^ was RMB351.4 million (US$50.9 million), compared with RMB327.7 million in the same period in 2025.

Research and development expenses were RMB193.3 million (US$28.0 million), decreased by 14.5% from RMB226.2 million in the same period in 2025 and increased by 1.6% from RMB190.2 million last quarter.

Use of Non-GAAP Financial Measures

The unaudited condensed consolidated financial information is prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In evaluating our business, we consider and use certain non-GAAP measures, Non-GAAP gross profit, Non-GAAP gross margin, Non-GAAP operating (loss) profit, Non-GAAP operating (loss) profit margin, Non-GAAP EBITDA, Non-GAAP EBITDA margin, Non-GAAP net loss and Non-GAAP net loss margin, as supplemental measures to review and assess our operating performance. The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with U.S. GAAP. We define Non-GAAP gross profit as gross profit excluding share-based compensation expenses allocated in the cost of revenues, and we define Non-GAAP gross margin as Non-GAAP gross profit as a percentage of revenues. We define Non-GAAP operating (loss) profit as operating loss excluding share-based compensation expenses and amortization of intangible assets, and we define Non-GAAP operating (loss) profit margin as Non-GAAP operating (loss) profit as a percentage of revenues. We define Non-GAAP net loss as net loss excluding share-based compensation expenses and foreign exchange (gain) loss, and we define Non-GAAP net loss margin as Non-GAAP net loss as a percentage of revenues. We define Non-GAAP EBITDA as Non-GAAP net loss excluding interest income, interest expense, income tax expense (benefit) and depreciation and amortization, and we define Non-GAAP EBITDA margin as Non-GAAP EBITDA as a percentage of revenues. We present these non-GAAP financial measures because they are used by our management to evaluate our operating performance and formulate business plans. We also believe that the use of these non-GAAP measures facilitates investors’ assessment of our operating performance.

^4^ Non-GAAP net loss is defined as net loss excluding share-based compensation expenses and foreign exchange (gain) loss, and we define Non-GAAP net loss margin as Non-GAAP net loss as a percentage of revenues. See “Use of Non-GAAP Financial Measures” set forth at the end of this press release.

^5^ Non-GAAP EBITDA is defined as Non-GAAP net loss excluding interest income, interest expense, income tax expense (benefit) and depreciation and amortization, and we define Non-GAAP EBITDA margin as Non-GAAP EBITDA as a percentage of revenues. See “Use of Non-GAAP Financial Measures” set forth at the end of this press release.

These non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. These non-GAAP financial measures have limitations as analytical tools. One of the key limitations of using these non-GAAP financial measures is that they do not reflect all items of income and expense that affect our operations. Further, these non-GAAP measures may differ from the non-GAAP information used by other companies, including peer companies, and therefore their comparability may be limited.

We compensate for these limitations by reconciling these non-GAAP financial measures to the nearest U.S. GAAP performance measure, all of which should be considered when evaluating our performance. We encourage you to review our financial information in its entirety and not rely on a single financial measure.
