Auditor Report To the EXAT’s Board of Directors Qualified opinions The Office of the Auditor General of Thailand (OAG) audited the EXAT’s financial statements, which comprise the Financial Position Statement as of 30 September 2020, the Comprehensive Income Statement, the Equity Change Statement, and the Cash Flow Statement for the year ending on the same day, including the notes to the financial statements and to significant accounting policies. The OAG was opined that, except for the effects and exceptions of inadequate disclosures of the said matters in the Section : Criteria for Expressing Qualified Opinions, the above financial statements revealed the EXAT’s financial position as of 30 September 2020, as well as its operating results and cash flow statement for the year ending on the same day correctly as they should in the substantive matters based on the Thai Financial Reporting Standards. Criteria for expressing qualified opinions. Non-recognition of accounting transactions from signing the Second Stage Expressway Agreement (Si Rat Expressway and the ‘D’ Section) and the Bang Pa-in-Pak Kret Expressway Agreement (Udon Ratthaya Expressway) (Revisions) As discussed in the notes to the financial statements, Section 4.23.5 : The Second Stage Expressway Agreement (Si Rat Expressway and ‘D’ Section) and the Bang Pa-in-Pak Kret Expressway Agreement (Udon Ratthaya Expressway) (Revisions), which aimed to resolve disputes between the EXAT and its contractual parties, the OAG considered relevant formation and then outlined key issues of signing the revised agreements, as follows : 1) There are many lawsuits where the EXAT’s contractual parties had taken actions to end legal execution, and individual lawsuits were different in terms of contents, including those with the court’s final judgment that the EXAT shall pay for indemnification, those under consideration both in the court and arbitral tribunal, and other disputes as a result of granting concessions of the same nature. 2) The revised agreements were intended to settle the lawsuits and disputes which would impose obligations of the EXAT in the case where it lost, and these revised agreements would result in the EXAT having the obligation to extend the period of sharing its revenue with its contractual parties. 3) The original agreements required that the contractual parties construct the expressways and transfer the expressway ownership to the EXAT immediately upon their completion, with its contractual parties entitled to manage the expressways, provide expressway service, and earn a share of the revenue The Office of the Auditor General of Thailand (OAG) 96

based on what was agreed-upon in the agreements. The revised agreements indicate that its contractual Annual Report 2020  Expressway Authority of Thailand parties shall have the right to manage the expressways, provide expressway service, and earn a revenue share equal to what was agreed-upon in the original agreements without constructing any additional assets or making an additional investment. An examination of the evidential documents used for considering the extension of the period of the original agreements and facts in the revised agreements suggested that the EXAT hadn’t not pay off the disputes-related debt in cash, but it would extend the period of the original agreements to entitle its contractual parties to manage, and provide the service of, the expressways under the terms and conditions included in revised agreements and would spend the share of potential toll revenue in the future on compensating for the sources of obligation in the disputes. The EXAT analyzed the guidelines for negotiation to determine an appropriate extension of years for the agreements by calculating the sources of obligation for the lawsuits and disputes in the case where the lawsuits and disputes were settled by not requiring its contractual parties to invest in the construction of the double deck values at 78,461 million baht. The OAT considered that the origin of the revision of the agreements was the acknowledgment of the debt and payment for the debt by extending the period for its contractual parties to earn a revenue share. In the past, the EXAT assessed that it would win the lawsuits and would not have to pay any damages or compensation; however, the revised agreements involved the EXAT in the obligation to share its revenue with its contractual parties without receiving any other additional benefits. This had an impact on its accounting transactions and financial statements. Nonetheless, the EXAT ’s management considered that the disputes were settled, so there was no need to recognize any transactions, which aimed to reflect the acknowledgement of the disputes-related debt and debt payment by extending the period for its contractual parties to receive a revenue share. The OAG considered that the methods used for recording accounting transactions and preparing the financial statements of the EXAT did not reflect the true economic content of the lawsuit and dispute settlement through extending the agreement period. The OAG regarded that if the EXAT had considered the actual economic content of the lawsuit and disputes settlement on the day when the revised agreements were signed, the EXAT should have recorded the recognition of the liabilities as a result of the lawsuits and disputes on which the EXAT made negotiation to settle them and should have recorded additional expenses on the lawsuits and disputes to those recognized when the Supreme Administrative Court ruled that the EXAT shall pay a compensation for a reduction in revenue as a result of the construction of competitive expressways and shall record the recognition of the transaction on granting the right to its contractual parties to receive a share of the toll revenue based on the revised agreements to pay off the debt as a deferred revenue while recognizing it as a revenue over the agreement period. As described in the note to the financial statements, Section 4.17 : Deferred Revenue, the EXAT recorded the account of the deferred revenue from its joint ventures only the parts where it had recognized based on the Supreme Administrative Court’s ruling that the EXAT shall pay a compensation for a reduction in revenue as a result of the construction of competitive expressways and interest incurred which were valued at 4,468.89 million baht and recognize this as a revenue over the period of the revised agreements. As for transactions on the liabilities and expenses on the debt for the lawsuits and disputes on which the EXAT negotiated for settlement under the terms and conditions included in the revised agreements, they were not recognized by the EXAT. The Office of the Auditor General of Thailand (OAG) 97

If the EXAT updates the financial statements for the year ending on 30 September 2020 to ensure that they are correct as they should be under the Thai Financial Reporting Standards based on the assumption that the source of the obligation valued at 78,461 million baht is the total amount of debt that the EXAT has considered for making negotiation on dispute settlement and for determining the appropriate number of years for the extension of the agreement period. This will have material effects, as follows : 1) The Financial Position Statement as of 30 September 2020 must show an additional deferred revenue (as a result of granting the right to its contractual parties to earn a share of the toll revenue under these revised agreements for lawsuit and dispute settlement) of approximately 73,992.11 million baht, which will reduce the equity by the same amount. 2) The Comprehensive Income Statement for the year ending on 30 September 2020 must show the expenses on debt for the lawsuits and disputes on which the EXAT has negotiated for settlement under the terms and conditions included in the revised agreements, amounting to approximately 73,992.11 million baht. This will change the operating result from the net profit of 6,420.96 million baht to the net loss of approximately 67,571.15 million baht. Inadequate disclosure on the extension of the agreement period (Revisions) The notes to the financial statements for the year ending on 30 September 2020, Section 4.23.5, Subject : The Second Stage Expressway Agreement (Si Rat Expressway and the ‘D’ Section) and the Bang Pa-in-Pak Kret Expressway Agreement (Udon Ratthaya Expressway), (Revisions) disclosed 10 disputes with the total capital of 55,874.08 million baht, which were cancelled and revoked but didn’t disclose the entire number of the lawsuits and disputes and the total amount of money cancelled and revoked. Originally, they were disclosed in the notes to the 3-month Interim Financial Data ending on 31 December 2019, Section 4.21.1 : Eleven Disputes between Joint Ventures with the capital of 128,099.55 million baht. In addition, they did not disclose information about the amount of the sources of obligation for the lawsuits and disputes which were taken into account so that they were settled by extending the agreement period until 31 October 2035. Thus, the data and facts provided in the said notes were insufficient for the financial statement users to understand the substantive matters of the extension of the concession period in the revised agreements. The Office of the Auditor General of Thailand (OAG) conducted the audit in accordance with the state audit standards and accounting audit standards. Our responsibilities are described in the Section : The Auditor’s Responsibilities for the Audit of Financial Statements in out report. We are independent of the Company’s business in accordance with the standard criteria for the state audit specified by the State Audit Commission and the Codes of Ethics for Professional Accountants by the Federation of Accounting Professions under the Royal Patronage of his Majesty the King in relation of the audit of financial statements. We have fulfilled other ethical responsibilities in accordance with the standard criteria for the state audit and the codes of ethics. We believe that the audit evidence we have obtained is sufficient and appropriate to serve as the criteria for expressing qualified opinions. Other information The EXAT’s management are responsible for the other information, which consists of information to be included in the Annual Report, but this excludes the financial statements and the Auditor Report to be included in the Annual Report. The management will have to prepare the Annual Report for the OAG after the date specified in the Auditor’s Report. The Office of the Auditor General of Thailand (OAG) 98
