ANNOUNCEMENT

REVISION OF ANNUAL CAPS FOR CERTAIN CONTINUING CONNECTED

TRANSACTIONS IN RELATION TO THE 2024

KINGSOFT FRAMEWORK AGREEMENT

REVISION OF ANNUAL CAPS FOR CONTINUING CONNECTED TRANSACTIONS

Reference is made to the Announcement in relation to, among others, the 2024 Kingsoft Framework Agreement entered into between the Company and Kingsoft Corporation. Pursuant to the 2024 Kingsoft Framework Agreement, during the period from January 1, 2025 to December 31, 2027, the Group will provide cloud services to Kingsoft Group, and Kingsoft Group will provide comprehensive property services, comprehensive technology services, and property lease services to the Group.

Due to the Group’s increasing demand of leasing from Kingsoft Group in light of its future business planning and administrative needs, the Board resolved to revise the annual caps for the comprehensive property services and the property lease services provided by Kingsoft Group to the Group for the two years of 2026 and 2027, while the annual caps for the remaining transactions under the 2024 Kingsoft Framework Agreement for the two years of 2026 and 2027 will remain unchanged.

HONG KONG LISTING RULES IMPLICATIONS

As at the date of this announcement, Kingsoft Corporation directly held approximately 32.94% of the Shares, thus is a connected person of the Company as defined under the Hong Kong Listing Rules. Accordingly, the 2024 Kingsoft Framework Agreement and the transactions contemplated thereunder constitute continuing connected transactions of the Company under Chapter 14A of the Hong Kong Listing Rules.

As the highest applicable percentage ratios in respect of the revised annual caps for the comprehensive property services and the property lease services provided by Kingsoft Group to the Group under the 2024 Kingsoft Framework Agreement for the two years of 2026 and 2027 are more than 0.1% but less than 5%, the comprehensive property services and the property lease services provided by Kingsoft Group to the Group under the 2024 Kingsoft Framework Agreement are subject to the reporting, announcement and annual review requirements, but are exempt from the independent shareholders’ approval requirement under Chapter 14A of the Hong Kong Listing Rules.

From January 1, 2026 to the date of this announcement, the actual transaction amounts for the comprehensive property services and the property lease services provided by Kingsoft Group to the Group under the 2024 Kingsoft Framework Agreement have not exceeded their respective original annual caps for the year ending December 31, 2026.

Basis of determination of the revised annual caps

The revised annual caps for the fees payable by the Group in respect of the comprehensive property services under the 2024 Kingsoft Framework Agreement for the two years of 2026 and 2027 are determined with reference to, among others, (i) the historical transaction amounts and fees charged by Kingsoft Group; (ii) the current and expected future office space demand of the Group; and (iii) the fair market rates for similar services.

The revised annual caps for the maximum value of right-of-use asset of the Group in respect of the property lease under the 2024 Kingsoft Framework Agreement for the two years of 2026 and 2027 are determined with reference to, among others, (i) the historical transaction amounts for the year ended December 31, 2025; (ii) the business development plan of the Group and the potential future lease arrangements; and (iii) the fair market rates for similar services.

For other reference factors regarding the basis of determination of the revised annual caps, please refer to the section headed “Reasons for and benefit of the revised annual caps” in this announcement.

Reasons for and benefit of the revised annual caps

In light of the Group’s future business planning, administrative needs, and changes in the status of certain properties, the Group intends to adjust the leasing models for certain properties accordingly. Specifically, instead of the Group directly leasing certain properties, Kingsoft Group will lease certain properties as a contracting party and then sub-lease them to the Group for use. Subject to the pricing basis under the 2024 Kingsoft Framework Agreement, the prices at which Kingsoft Group sub-leases certain properties to the Group shall be the same as the prices at which the Group directly leases such properties. Based on this, the Group will enter into property sublease agreements with Kingsoft Group for such properties, and such properties will be recorded in the Group’s consolidated financial statements as right-of-use assets upon execution of such agreements. The Group expects the annual comprehensive property service fees payable to be approximately RMB5.20 million (unaudited) and the value of the right-of-use assets recognized to be approximately RMB49.59 million (unaudited). Therefore, the Board anticipated that the original cap amounts for the two years of 2026 and 2027 will be insufficient to meet the Group’s leasing demands, and has resolved to correspondingly increase the annual caps for the fees payable in respect of the comprehensive property services and the maximum value of right-of-use asset in respect of the property lease under the 2024 Kingsoft Framework Agreement for the two years of 2026 and 2027.

Leveraging the long-standing cooperation between the Kingsoft Group and the Group as well as the familiarity of products and services of each party, the entering into of the 2024 Kingsoft Framework Agreement is expected to mutually benefit both parties. The provision of comprehensive property services and property lease services by Kingsoft Group to the Group will better leverage the mature infrastructure and services coverage already established by Kingsoft Group to provide a more stable and undisrupted office environment to the Group with the costs that are in line with prevailing market prices.
