True Corporation Public Company Limited (SET: TRUE) previously filed a petition with the Central Administrative Court to revoke the arbitral awards in the case where CAT Telecom Public Company Limited (currently National Telecom Public Company Limited (“NT”)) claimed Total Access Communication Public Company Limited (dtac) (currently the Company) for additional benefits from the interconnection charge (“IC”) revenue for the 17 th and 20th concession years. NT also filed a petition for enforcement of the arbitral awards for the aforementioned concession years.
The Company disclosed a significant update the issue through the Stock Exchange of Thailand that on September 24, 2025, the Central Administrative Court rendered its judgments as follows:
1) With respect to the case concerning the 17 th concession year, the Court rendered its judgment to partially revoke the arbitral award, specifically the portion where the arbitral tribunal determined an interest rate exceeding the rate prescribed by law, and to enforce the arbitral award only in the part where the interest rates are not exceeding the rates prescribed by law. According to the Court’s judgment, the Company is ordered to pay THB 3,957 million, together with interest calculated from the principal amount at the rate of 7.5% per annum from November 16, 2012 until April 10, 2021, and at the rate of 5% per annum from April 11, 2021 onwards until full payment is made. The payment must be completed within 90 days from the date the case becomes final.
2) With respect to the case concerning the 20th concession year, the Court rendered its judgment to partially revoke the arbitral award, specifically the portion where the arbitral tribunal determined an interest rate exceeding the rate prescribed by law. However, the Court is considering and has not yet rendered its judgment on the case where NT requested enforcement of the arbitral award.
The above judgments of the Central Administrative Court can be appealed to the Supreme Administrative Court; therefore, the cases are not yet final. The Company respectfully disagrees with the said judgments, and will exercise its right to appeal to the Central Administrative Court’s judgments to the Supreme Administrative Court within 30 days from the date of acknowledgment of the judgment. Therefore, the Company is not obligated to make any payment to NT pursuant to the above Central Administrative Court’s judgments.
