After thorough evaluation, the Board of Directors of the Company has made the interim decision not to appoint a successor depositary at this time, as maintaining the ADR program is no longer cost-effective. This decision is not final and will be revisited as circumstances evolve.

While this decision reflects the Company’s current assessment of cost-benefit considerations, the Company retains the flexibility to reevaluate this position should market conditions or shareholder needs materially change in the future. The Company will continue to monitor the situation and may consider engaging a new depositary if warranted.

Notwithstanding this interim arrangement, the Company remains committed to complying with applicable reporting requirements under the U.S. Securities Exchange Act of 1934. The Company will maintain regular filing schedule, including annual reports on Form 20-F and current reports on Form 6-K, which will remain accessible to investors through the SEC's EDGAR system at www.sec.gov.
