Business Report for the 44th Fiscal Year

Pursuant to Article 447-2(Preparation of Business Report) and Article 449 of the Commercial Act (Approval and Public Notice of Financial statements, etc.), KT’s 44th annual business report is as follows:

In 2025, KT focused on strengthening business capabilities and driving innovation to transform into an AICT Company. Through strategic partnerships with global big tech companies, KT launched new B2B AX services and secured key reference cases, while advancing AX-based innovation across core CT, media, and network businesses. KT also continued to enhance management structure and profitability by streamlining underperforming businesses and optimizing the group portfolio. By reinforcing AX capabilities and advancing business innovation, KT aims to sustain balanced growth across both B2B AX businesses—including AI, Cloud, and DC—and its B2C operations.

In the wireless business, as of the end of 2025, 5G mobile subscribers reached 11.54 million, accounting for 82% of total MNO subscribers. Growth in MVNO subscribers and roaming revenue supported stable revenue growth. In the Broadband and IPTV businesses, the proportion of high-value products—such as GiGA Internet and premium IPTV plans—continued to increase.

In the B2B segment, demand for corporate communication services, including enterprise broadband and enterprise messaging, increased, alongside continued growth in AI/IT businesses. KT also pursued structural improvements in B2B profitability by streamlining low-margin and non-core businesses.

KT’s subsidiaries likewise sustained both business growth and profitability improvement. In the AI/IT domain, kt cloud expanded cloud and data center capabilities to meet rapidly growing AX demand. In real estate, kt estate achieved strong performance in hotel business and asset development. In media and content, KT realigned the portfolio centered on KT StudioGenie. In financial services, Kbank showed balanced growth across key operating indicators, including deposits, loans, and customer base.

In 2025, KT recorded standalone operating revenue of KRW 19.324 trillion, operating profit of KRW 1.305 trillion, and net profit of KRW 1.062 trillion. As of the end of 2025, the status of major service subscribers is as follows:


Subscribers (Unit: 10K)	Mobile	Broadband	IPTV	PSTN	VoIP
December 31, 2025	2,899	1,017	953	772	317
December 31, 2024	2,613	996	945	826	321

Report on the Criteria and Methods for Director Compensation

Pursuant to Article 31 (Remuneration and Severance Allowance for Directors) of the KT’s Articles of Incorporation, the criteria in place to determine the remuneration for executive directors and the method of payment are reported as follows:

Summary of Director Compensation Program

KT’s inside director compensation program is designed to reward management for both short-term and long-term performances. The Company believes it is critical to maintain a well-balanced incentive program that encourages the management not only to achieve short-term performance but also to strive for the Company’s long-term value enhancement. The Evaluation and Compensation Committee sets annual goals and conducts evaluations of the management annually. The Committee is composed entirely of outside directors.

The compensation program for outside directors consists of cash and annual stock grants which are subject to a one-year lock-up period beginning at the start of the year it is awarded. The stock grant is not subject to any performance criteria and has been introduced to ensure that outside directors have “skin in the game” to align their interests with all shareholders.

Components of Inside Director Compensation

The remuneration for inside directors consists of annual salary (base salary and position allowance), performance incentives (short and long-term), and severance pay.

i.Base Salary: Paid in 1/12 monthly installments (prorated for partial periods of service)

ii.Position Allowance: Paid in 1/12 monthly installments (prorated for partial periods of service)

iii.Short-Term Incentives: Paid after the end of each fiscal year based on management performance, within the aggregate director compensation limit (prorated for partial months of service)

-If term ends in the first half of the year, the incentive will be based on the prior year’s performance and paid within one month after retirement; if it ends in the second half, it will be based on the retirement year’s performance paid in the following year.

iv.Long-Term Incentives: Granted in shares following each fiscal year based on the achievement of applicable long-term performance metrics, within the aggregate director compensation limit

v.Severance Pay: Paid in accordance with the Company’s executive severance payment policy approved by the General Meeting of Shareholders.

Criteria for Evaluation

The Company’s performance evaluation process begins with the setting of annual goals by the Evaluation and Compensation Committee. Annual goals are established in alignment with the Company’s overall operational and financial goals with an emphasis on improving shareholder value.

Short-term performance is comprised of quantitative and qualitative factors. Typically, quantitative goals are related to financial and operational performances, whereas qualitative goals are focused on achieving operational and strategic goals to further enhance long-term competitiveness. Please refer to “Report on Evaluation Results of Management Performance for the 44th Fiscal Year” for results of the Representative Director’s short-term performance for FY2025.

Long-term performance incentives are provided to reward management’s contribution to long-term financial and operational competitiveness. Incentives are offered in accordance with share price performance, Group revenue, Group operating profit, and qualitative performance indicators.
