Item 4 of the Original Schedule 13D is hereby amended and supplemented by adding the following: On April 28, 2026, the Reporting Person delivered a non-binding written proposal (the "Proposal Letter") to the Board of Directors of the Issuer (the "Board") to acquire, through a comprehensive share exchange under applicable Korean law (the "Transaction"), all of the outstanding Common Shares (including those represented by ADSs) of the Issuer not currently owned by the Reporting Person, representing approximately 32.9% of the Issuer's outstanding Common Shares, at a cash purchase price of US$11.25 per ADS (equivalent to US$225.00 per Common Share) (the "Offer Price"). The Proposal Letter provides, among other things, that: (i) the Transaction will be conditioned upon the recommendation of a special committee of independent directors of the Board (the "Special Committee") advised by independent financial and legal advisors, and the execution of a mutually agreed definitive agreement; (ii) the Transaction will be subject to the affirmative vote of at least 95% of the Issuer's outstanding Common Shares, including a majority of the votes cast by shareholders other than the Reporting Person; (iii) the Transaction will not be subject to any financing condition; and (iv) the Reporting Person, in its capacity as the Issuer's controlling shareholder, intends to vote its Common Shares in favor of the Transaction, will not support any alternative transaction involving the Issuer, and has no present intention to reduce its shareholding in the Issuer. The Proposal Letter is a non-binding expression of interest. Accordingly, no assurance can be given that any definitive agreement will be executed or that the Transaction or any related transaction will be consummated. The Reporting Person reserves the right to amend or withdraw the Proposal Letter at any time, in its sole discretion, and to negotiate the terms of any definitive agreement, including with respect to pricing, structure, and conditions. Concurrently with the delivery of the Proposal Letter, the Reporting Person issued a press release announcing the submission of the Proposal Letter (the "Press Release"). The foregoing descriptions of the Proposal Letter and the Press Release do not purport to be complete and are qualified in their entirety by reference to the full text thereof, copies of which are filed as Exhibit 99.2 and Exhibit 99.3, respectively, and are incorporated herein by reference. If consummated, the Transaction would result in the Issuer becoming a wholly owned subsidiary of the Reporting Person, the Issuer's ADSs being delisted from the NASDAQ Global Select Market, and the termination of the Issuer's reporting obligations under Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the deregistration of the Issuer's ADSs and Common Shares under Section 12 of the Exchange Act as promptly as practicable following consummation of the Transaction. Except as set forth in this Amendment and the agreements described herein, the Reporting Person does not currently have any plans or proposals that relate to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D. However, as part of its ongoing evaluation of the Transaction, the Reporting Person may at any time modify its plans, propose or effect additional transactions or changes, or take any other actions with respect to its investment in the Issuer, in each case subject to applicable law.

Item 5 of the Original Schedule 13D remains unchanged from Amendment No. 1 and is incorporated herein by reference.

Item 6 of the Original Schedule 13D remains unchanged from Amendment No. 1 and is incorporated herein by reference.
