The Government of the Republic of Rwanda and related entities filed a counterclaim against KT Corporation in an ongoing PCA arbitration proceeding, seeking approximately USD 386 million (KRW 512.4 billion) in damages for alleged breaches of a shareholders' agreement. This follows KT's initial claim for roughly USD 152 million based on the Counterclaimants' failure to meet put option obligations. The counterclaim represents about 2.63% of KT's consolidated equity as of December 31, 2025. KT intends to vigorously dispute the validity of the calculation basis and defend its position during the proceedings. KT Corporation operates in the telecommunications industry.
