Kingsoft Cloud and CEC D-Commerce Tech Form Strategic Partnership

to Drive Healthcare Cloud Development in China

BEIJING, CHINA, September 21, 2020 – Kingsoft Cloud Holdings Limited (“Kingsoft Cloud” or the “Company”) (NASDAQ: KC), a leading independent cloud service provider in China, today announced that the Company has recently entered into a multi-year strategic framework agreement (the “Agreement”) with CEC D-Commerce Technology (Shanghai) Co., Ltd. (“CEC D-Commerce Tech” ), to invest in and expand healthcare cloud services, re-engineering the data services layer, and improving the analytical capabilities of healthcare organizations across China.

Pursuant to the Agreement, both companies will jointly develop cloud-based healthcare solutions, and provide healthcare organizations with powerful data analysis and application tools which can significantly reduce on-premise IT construction, operation and maintenance costs for hospitals and healthcare agencies across China. Both parties will execute cloud projects at the national, provincial and municipal levels. Flagship projects will first be implemented within a number of regions, and then be gradually expanded to provinces and cities across the country.

CEC D-Commerce Tech will capitalize on its extensive connections with the healthcare supply chain to generate qualified sales leads and commit resources to facilitate healthcare projects, while Kingsoft Cloud will leverage its existing public cloud technologies to further research and develop proprietary technology in healthcare solutions, advise best-fit cloud adoption patterns, achieve enhanced technical interoperability, and successfully execute and deliver projects.

Kingsoft Cloud’s strategic expansion into the healthcare industry is primarily due to the following reasons:

1) Demand for healthcare cloud-native services is still in its infancy and presents an enormous growth opportunity in China. An IDC report asserts that IT spending on cloud services for China’s healthcare industry is expected to reach RMB17 billion by 2023.

2) National policies are supportive of healthcare digitalization, providing guidance on timetable, technology standards, data requirements and accommodative budget allocations.

3) The rapid onset and impact of the COVID-19 pandemic has urged national and local governments to digitalize the healthcare industry. As a result, there has been sustainable demand for the establishment of standardized data centers, unified information standards and data services for the healthcare industry across China.

4) Healthcare use cases for big data is multifaceted, spanning personal health, medical services, disease control and health preservation. The integration of various data sources and the growing need for data analysis create recurring demand for healthcare cloud services.

This new partnership with CEC D-Commerce Tech will enable Kingsoft Cloud to establish a solid foothold in a market with significant growth prospects.

Kingsoft Cloud’s robust cloud infrastructure, end-to-end healthcare solutions and unparalleled service capabilities will support healthcare data centers, along with healthcare information, medical insurance and medical community platforms. As an independent cloud service provider with no exposure to healthcare business, Kingsoft Cloud will provide secure, compliant and resilient data services, break down data silos and enable on-demand access to the data. By leveraging its expertise in enterprise service delivery, Kingsoft Cloud is best-positioned to manage the complexities of running enterprise programs, which is critical for operating in the highly regulated and standardized healthcare industry. CEC D-Commerce Tech is one of the leading companies advocating for favorable national policy to be deployed across China. It has deep access to a pool of project resources for the healthcare sector. This cooperation will expand Kingsoft Cloud’s integration into the operational infrastructure of the healthcare industry.

In order to fully capture this long-term growth opportunity, Kingsoft Cloud plans to devote additional resources, hire talent with specialized healthcare cloud computing experience and further invest in upgrading the Company’s technology capabilities for the healthcare industry.
