Korean Air (KE, Seoul Incheon) has been ordered by South Korea's Financial Supervisory Service (FSS) to correct its merger registration statement relating to its planned absorption of Asiana Airlines (OZ, Seoul Incheon), according to notices published on the regulator's electronic disclosure system.

The FSS said Korean Air's registration statement failed to satisfy statutory requirements because it contained false statements, omitted material information, or included unclear descriptions of significant matters.

In a separate notice, the regulator said Asiana's major matters report on the merger also required corrections, after it found material information had been omitted or falsely stated, among other deficiencies.

Under South Korea's Capital Markets Act, the effectiveness of Korean Air's registration statement is suspended until the submission of a corrected filing.

The regulator also warned that the timetable for securities issuance, including subscription dates, may be delayed because of the correction request.

The FSS did not disclose the specific deficiencies identified in either filing. However, according to local outlet Newswatch, an FSS official said further details could not be released because they could affect the companies' share prices.

The South Korean Ministry of Land, Infrastructure and Transport (MOLIT) recently granted conditional approval for the merger, clearing the final domestic regulatory hurdle. Korean Air has said it aims to complete the remaining procedures and merge with Asiana on December 17, 2026.
