The five audited annual reports cover years ended 31 December 2021 to 2025. The interim results cover the six months ended 30 June 2026 and have not been audited or reviewed. Each source keeps its own reporting date, units and Company or Group scope.

The annual shareholder register is dated 18 March 2026. Percentages use 633,034,104 issued ordinary shares excluding 22,464,500 treasury shares. The interim report records the same issued and treasury share counts at 30 June 2026. No later complete registered shareholder list is asserted.
The twenty largest registered or depository holders are not a list of distinct beneficial owners. Nominee positions are not mapped to underlying investors. Ng Soon Kai's direct interest and his deemed interest in 6,000,000 shares held by spouse Chua Seok Yin may overlap the registered list and must not be added again.
The printed top twenty total and sum of printed percentages are 63.83%. Dividing the printed 404,141,986 shares by the printed denominator rounds to 63.84%. All original shares and percentages are retained. Public shareholding is approximately 72% as stated by the issuer.

Group structure
The five audited annual reports cover years ended 31 December 2021 to 2025. The interim results cover the six months ended 30 June 2026 and have not been audited or reviewed. Each source keeps its own reporting date, units and Company or Group scope.
Statements about Myanmar legal and regulatory matters are dated disclosures attributed to the issuer, its commissioned legal advisers and its auditor. They do not establish present legal compliance.
The year-end annual source lists thirteen current subsidiaries, including a dormant company explicitly labelled dormant. Parent, Group and non-controlling interests are different columns. Goldwater Eagle Limited was struck off on 2 May 2025 and is not shown as a current operating subsidiary.
The annual report identifies KPR as a 40.00% associate and NCT as a 12.63% associate at 31 December 2025. The interim report records NCT dilution to 12.00% on 20 January 2026, with significant influence and associate accounting retained. Former associate IOI was liquidated in February 2025. The 40% MBI joint venture was disposed of on 4 September 2025.
GII became indirectly wholly owned through GCL following the completed internal transfer on 7 January 2026. The Group's 60% equity interest in GJOC and its separate 60% participating interests in the Myanmar IPRCs were transferred internally to GII on 20 January 2026. Equity and contractual participating rights are different interests.
The external GII disposal agreement announced on 22 June 2026 is conditional. The interim report explicitly confirms it had not completed at 30 June 2026, and the assets were not classified as held for sale because conditions precedent had not been satisfied. Completion is not established by the reviewed disclosures.
FISE is a Thai joint operating company held 49% through wholly owned IRET, with joint control and unanimous approval required for material decisions. It is not a majority owned subsidiary. The July school solar service agreement and the agreement concerning five commissioned rooftop projects are separate dated project disclosures; an agreement does not itself establish later transfer completion.
The 5 October 2026 announcement states that IES signed a restructuring agreement and a new convertible bond agreement with PT Berkat Bersatu dated 2 October 2026. Ancillary vessel transfer, service and guarantee obligations were due within seven business days. Their completion is not inferred. Vessel value was not independently valued, and the announcement's pro forma financial effects are illustrative.
