News Summary:

On February 5, 2026, KT's Board of Directors confirmed Yoon-Young Park as the final candidate for CEO. Previously, on February 4, KT developed a quantum key distribution (QKD) system capable of generating up to 300,000 encryption keys per second, more than doubling the performance of its previous system introduced in early 2024. The company stated this system uses proprietary technology and quantum mechanical principles to prevent key duplication and detect eavesdropping on physical communication lines. This followed news from February 3, when South Korea's National Pension Service (NPS) shifted its investment purpose in KT Corp. from passive to active, a move widely interpreted as a precursor to potential shareholder action ahead of the company’s March annual general meeting.
