Judgment/Resolution of Lawsuit

In March 2018, AJ Energy LLC (“AJ Energy”) filed a lawsuit against Woori Bank in the Supreme Court of the State of New York, which was later transferred to the United States District Court for the Southern District of New York (the “District Court”), seeking to recover an alleged transfer to Woori Bank from AJ Energy’s foreign investors through an intermediary bank in the amount of EUR 8 billion.

In September 2019, the District Court granted Woori Bank’s motion to dismiss and its motion for sanctions. In its opinion and order, the District Court stated that the evidence submitted by AJ Energy in its complaint were generally forgeries and that no actual evidence supporting the alleged transfer was submitted. Accordingly, the lawsuit was dismissed with prejudice in its entirety, and the District Court ordered AJ Energy and its counsel to pay Woori Bank’s attorney’s fees and costs associated with filing the motions. In October 2019, AJ Energy filed an appeal against the District Court’s order to the United States Court of Appeals for the Second Circuit (the “Second Circuit”).

In September 2020, the Second Circuit affirmed the judgment of the District Court for substantially the same reasons articulated by the District Court. Woori Bank will continue to monitor and proactively respond to any such matters relating to AJ Energy.
