Kingsoft Oce 2025 Sustainability ReportStrategyThe Company fully recognizes the potential negativeimpacts arising from inadequate management of datasecurity and user privacy protection. Deficiencies inthe Company's relevant management measures andmechanisms could have repercussions throughoutits operations and downstream value chain. On onehand, the Company's own operations would directlyface compliance pressure and the risk of operationaldisruption. On the other hand, downstream users couldsuffer direct losses from data leakage. Such incidentscould not only trigger a crisis of client trust but alsopotentially damage the collective reputation of the entireindustry.During the year, we reviewed the potential financialimpacts arising from risks related to data security anduser privacy protection. Violations of laws and regulationsrelated to data security and privacy protection mayresult in the Company being involved in major negativeincidents such as data security breaches and privacyleaks, which in turn could subject the Company toregulatory penalties. To address such risks, the Companyneeds to invest in relevant software applications andhardware equipment. If data security and user privacyprotection controls are ineective, the impact of relatedrisks may manifest in the short term.To mitigate negative impacts and proactively addresssuch risks, the Company has established a data securityand privacy protection management system covering theentire lifecycle. It strengthens risk prevention measures,enhances emergency response and handling capabilities,improves internal and external audit mechanisms, anddeepens transparent communication with clients andsuppliers to uphold data security and privacy for allparties in the value chain.

During the reporting period, the Company was notsubject to regulatory penalties due to data security oruser privacy protection issues. In response to relevantregulatory requirements, the Company has madededicated investments in software and hardware relatedto data security and user privacy protection.

Kingsoft Oce 2025 Sustainability ReportScenario Analysis

We conducted a climate scenario analysis to gain an understanding of Kingsoft Oce'srisk levels under dierent climate scenarios. By fully considering the concentration ofrisk, impact magnitude, data availability and other factors, we prioritized a detailedassessment of the nancial impacts arising from physical risks and transition risks underlow-carbon and high-carbon scenarios for our oce locations.

This could demonstratethe Company's climate risk response ability across various scenarios. To enhance ourclimate resilience, the results of the climate scenario analysis will be applied to theformulation of climate response measures and transition plans.Under the selected high-emission and low-emission scenarios, the most criticalphysical risks and transition risks, i.e. the rise in average temperatures, extreme weatherevents such as typhoon, tornadoes, rainstorm, and flooding, as well as policy risks,were analyzed and identied by the Company. The section "Climate-related Risks andOpportunities Assessment" above shows the potential impacts of these risks on businessand operational processes.Based on the scenario analysis results, under the assumption of no signicant changesin the existing geographic locations and business models of our oce locations, theasset loss due to typhoon, tornadoes, rainstorm, and flooding is expected to showa slight upward trend in the medium to long term, but it is not expected to have asignicant nancial impact. As we cannot entirely avoid the losses caused by extremeweather events, a series of disaster prevention systems and emergency response planswere established for our oce locations, considering the occurrence of extreme climateevents during site selection to minimize relevant impacts. We purchased catastropheinsurance, all-risk construction insurance, and third-party liability insurance for thebuildings and devices of our newly built Wuhan Park to reduce the risk of asset loss dueto unforeseen events caused by extreme weather. In terms of transition risks, if relevantpolicy adjustments impact electricity prices, the electricity costs for leased data centersare expected to exhibit an upward trend in the medium to long term. To effectivelyreduce energy costs, the Company has prioritized leasing data centers that utilizeclean energy and green electronic equipment, mitigating the impact of electricity priceuctuations on energy usage costs.

24. Our key assumptions include: Mitigation measures for climate-related physical risks will remain largely unchanged in the future. An accelerated transition to low-carbon energy

will be pursued to address transition risks.

25. The analyses for the years 2030 and 2050 are based on the average changes under each scenario over the respective timeframes, used to assess the potential impacts of climate

risks across dierent periods.

26. When selecting scenarios, the Company considered the following factors: The analysis period of the scenarios align with the Company's strategic planning horizon. The climate

factors included in the scenarios eectively describe the potential climate pressures the Company may face in the future.

27. SSP2-4.5: A low-carbon emissions scenario (optimistic scenario), which describes carbon emissions peaking by 2040 and subsequently declining, alongside stable economic

Kingsoft Oce has established a remuneration system for all employees that is precisely incentivized,value-oriented, and inclusive. Centered on the integration of long- and short-term incentives and equalemphasis on strategy and risk control, we align company strategy, business priorities, and individualcontributions, and formulate dierentiated remuneration strategies based on employee sequence rank tostrengthen the eectiveness of talent incentives.

Long-term IncentivesShort-term Incentives

To ensure the scientific adaptation of remuneration system, we regularly cooperate with externalprofessional agencies to conduct salary surveys, constantly monitor employee salaries, and dynamicallybenchmark against peer enterprises. We place particular emphasis on ensuring the externalcompetitiveness and internal equity of compensation for our entry-level employees. In addition, theCompany places signicant emphasis on addressing gender pay gaps and ensuring equal pay for equalwork. Through regular reviews and analysis of employee remuneration data and other measures, weeectively monitor employee remuneration and ensure that all employees receive fair remuneration forequivalent roles and performance levels. Additionally, we advocate for a healthy work-life balance forour employees. In cases where extra work is required, we ensure through strict working hour monitoringand overtime management that employees working overtime receive appropriate compensation.

We continue to implement equity incentive plans to attractand retain outstanding talent through stock incentives, fullymotivating the Company's core team. All full-time employeesare eligible to participate in the selection. This year, we granteda total of 3,460,000 restricted shares to core managementpersonnel, key technical staff, and other employees whohave made significant contributions to the Company. Amongemployees below the senior executive level, the overallparticipation rate in the equity incentive program wasapproximately 30%.

54. Agile dialogue refers to an unstructured approach to managing employee performance and development throughout the year.

We consistently monitor employees' performance against their objectives, conducting annual team performance assessment through performance review andbiannual individual performance assessment using employee self-assessment, departmental superior assessment, and grade-by-grade calibration. Building uponthe existing foundation, our performance assessment process has strengthened the "calibration and alignment" phase.

The results of both team and individual performance assessments collectively inuence employees' bonuses, remuneration, and promotions. We arecommitted to fostering a more objective and equitable appraisal environment.

Performance Assessment

We have established systematic communication mechanisms for employees. Each employee can engage in one-on-one communication with their direct supervisorregarding performance appraisal results to gain clear development feedback and improvement suggestions. To ensure the quality and eective implementation ofcommunication, we have introduced a "post-interview questionnaire follow-up" mechanism. This reversely evaluates the actual execution of the interviews, ensuringthat communication is eectively carried out. Additionally, we provide employees with clear channels. Employees can initiate an appeal within a stipulated 7-daywindow period for performance appraisal and other questions. The Company has designated personnel responsible for managing the entire process and promptlyaddressing employee inquiries. Upholding principles of equality and fairness, the Company actively engages with all parties and, when necessary, convenes reviewpanels to address employee appeals.

We encourage regular agile dialogues between supervisors and employees,

offering timely guidance through communication to quickly adjust employees'work direction and deepen their understanding of their roles.
