Disclaimer:

The sales figures, including but not limited to power sold and revenues received therefrom (the “Estimates”), of Korea Electric Power Corporation (“KEPCO”) as presented above have been prepared for convenience only based on internal estimates of KEPCO as of the relevant meter reading dates and do not include power sold and revenues received from pumped storage units. These figures have neither been audited nor reviewed by KEPCO’s independent accountants, Deloitte Anjin LLC., or any other accountants. These Estimates may differ significantly from the actual results of operations of KEPCO, which KEPCO expects to publicly disclose in the future, in a number of ways, including but not limited to, elimination of internal profits and sales discount. KEPCO disclaims any liability in connection with the Estimates, and no reliance should be made upon these Estimates including in connection with, but not limited to, entering into any contract for the purpose of trading any securities of KEPCO or any other investment decision in respect of KEPCO or its securities.
