BEIJING, CHINA, June 3, 2020 – Kingsoft Cloud Holdings Limited (“Kingsoft Cloud” or the “Company”) (NASDAQ: KC), a leading independent cloud service provider in China, today announced its unaudited financial results for the first quarter ended March 31, 2020.

First Quarter 2020 Financial Highlights

“We are pleased to report strong operational and financial results in our first quarter as a public company. Our total revenues increased 64.5% year-over-year to RMB1,391.0 million, driven by solid growth in both public cloud and enterprise cloud services.” commented Mr. Yulin Wang, Chief Executive Officer of Kingsoft Cloud. “We believe the deeper penetration of cloud technology and commercial adoption of 5G will create long-term growth opportunities for both public cloud and enterprise cloud services in China. We are confident that our cutting-edge technology and ability to effectively execute our strategy will ideally position us to capture the growth opportunities the cloud industry will create in the future.”

“We remain committed to upholding the highest standards of corporate social responsibility and in response to the outbreak of COVID-19, we have devoted resources towards helping society and businesses readjusting to the new normal. For example, we rapidly developed new cloud solutions to support companies in various verticals that have seen demand during the pandemic such as online healthcare, education, remote working and entertainment among others.”

“In our F-1 prospectus, we provided revenue outlook in the first quarter of 2020 which ranged from RMB1,350.0 million to RMB1,400.0 million. Total revenues during the quarter came in at the top end of range at RMB1,391.0 million, representing an increase of 64.5% year-over-year and exceeding the growth of the public cloud industry in China in general.” added Mr. Henry He, Chief Financial Officer of Kingsoft Cloud.

“We achieved positive gross profit for the third consecutive quarter. And the Non-GAAP gross margin has continued to improve gradually for the last seven quarters. Non-GAAP gross margin increased rapidly, from -5.3% in the first quarter of 2019 to 5.3% in the first quarter of 2020, an improvement of 10.6 percentage points. Our non-GAAP EBITDA margin increased as well, up from -12.9% in the first quarter of 2019 to -2.8% in the first quarter of 2020, an improvement of 10.1 percentage points. Non-GAAP EBITDA margin has continued to improve steadily for consecutive seven quarters.

We have maintained a healthy balance sheet and sufficient liquidity. As of March 31, 2020, we had cash and cash equivalents, term deposits of RMB1.97 billion. On May 8, we have raised US$551.3 million of net proceeds from the IPO. Going forward, we will continue to maintain a healthy balance sheet and ensure sufficient investments in R&D and infrastructure.”

First quarter 2020 Financial Results

Total Revenues reached RMB1,391.0 million (US$196.4 million), an increase of 64.5% from RMB845.8 million in the same period of 2019. The increases were primarily due to the growth in public cloud services and enterprise cloud services for our premium customers.

2

Cost of revenues was RMB1,320.2 million (US$186.4 million), representing an increase of 48.2% from 890.9 million in the same period of 2019, primarily attributable to increase in IDC costs and depreciation and amortization costs. IDC costs increased by 36.1% to RMB920.2 million (US$130.0 million) from 676.3 million in the same period of 2019. The increase in IDC costs was in line with the Company’s expanding business and was partially offset by improved efficiency and utilization of bandwidth. Depreciation and amortization costs increased by 51.3% to RMB204.8 million (US$28.9 million) from 135.4 million in the same period of 2019, primarily due to new servers and other fixed assets purchased.

Gross profit was RMB70.8 million (US$10.0 million), compared to gross loss of RMB45.1 million in the same period in 2019. Gross margin was 5.1%, representing an increase of 10.4 percentage points from -5.3% in the same period in 2019.

Non-GAAP gross profit was RMB74.2 million (US$10.5 million), compared to Non-GAAP gross loss of RMB44.6 million in the same period in 2019. Non-GAAP gross margin was 5.3%, representing an increase of 10.6 percentage points from -5.3% in the same period in 2019. The increase was primarily due to our continued leverage on economies of scale.

Selling and marketing expenses were RMB88.0 million (US$12.4 million), representing an increase of 66.7% from RMB52.8 million in the same period in 2019, mainly due to an increase in share-based compensation expenses.

General and administrative expenses were RMB76.0 million (US$10.7 million), an increase of 116.3% from RMB35.1 million in the same period in 2019, mainly due to the increase in share-based compensation expenses, as well as salaries and welfare of management personnel.

Research and development expenses were RMB195.7 million (US$27.6 million), an increase of 57.3% from RMB124.4 million in the same period in 2019, primarily due to the increase in the salaries and welfare of research and development personnel.

Operating loss was RMB288.8 million (US$40.8 million), compared with RMB257.4 million in the same quarter of 2019.

Net loss was RMB331.6 million (US$46.8 million), compared with RMB201.4 million in the same quarter of 2019.

Non-GAAP net loss was RMB243.4 million (US$34.4 million), compared with RMB225.3 million in the same quarter of 2019.

3

Non-GAAP EBITDA was RMB-39.4 million (US$-5.6 million), compared with RMB-108.8 million in the same quarter of 2019. Non-GAAP EBITDA margin was -2.8%, compared to -12.9% in the same quarter of 2019. The steady increase of Non-GAAP EBITDA margin was due to the revenue growth and operating leverage.

Basic and diluted net loss per share was RMB0.39 (US$0.06), compared with RMB0.23 in the same quarter of 2019.

Cash and cash equivalents and short-term investments were RMB2,198.4 million (US$310.5 million) as of March 31, 2020, compared to RMB2,248.7 million as of December 31, 2019. The decrease was primarily driven by outbound cashflow associated with expansion of our business operations, partially offset by the net proceeds of RMB138.9 million from the issuance of Series D+ convertible redeemable preferred shares in December 2019.

Recent Developments

On May 8, 2020, Kingsoft Cloud successfully completed its initial public offering (the “IPO”) of 34,500,000 American Depositary Shares (“ADSs”) on the NASDAQ Global Select Market, at a price of US$17.0 per ADS, including 4,500,000 ADSs that underwriters exercised their over-allotment options in full. Each ADS represents 15 ordinary shares. The Company receive a total of approximately US$551.3 million of net proceeds from the IPO, after deducting the underwriting discounts and commissions.

Business Outlook

For the second quarter of 2020, the Company expects total revenues to be between RMB1.50 billion and RMB1.54 billion, representing a year-over-year growth of 60% to 65%. This forecast reflects the Company’s current and preliminary views on the market and operational conditions, which are subject to change.

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 (loss) profit, Non-GAAP gross margin, Non-GAAP EBITDA and Non-GAAP EDITDA 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 (loss) profit as gross (loss) profit excluding share-based compensation allocated in the cost of revenues, and we define Non-GAAP gross margin as Non-GAAP gross (loss) profit as a percentage of revenues. We define Non-GAAP net loss as net loss excluding share-based compensation, foreign exchange (gain) loss, changes in fair value of financial instruments and other (income) expense, net. We define Non-GAAP EBITDA as Non-GAAP net loss excluding interest income, interest expense, income tax expense 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. 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.
