In the summer of 2022, the laying of the high voltage cable between the two islands was completed and the construction of the High Voltage Substation in Santorini is progressing.

In November 2022 the tender process was completed and in February 2023 the contracts for the cables were signed for the remaining three islands of the southwest Cyclades (Folegandros, Milos, Serifos) which will integrate the entire island complex into the High Voltage System until the end of first semester of 2026.

In September 2023, the contracts of the High Voltage Substations for Folegandros, Milos and Serifos were signed, putting the entire project in construction phase.

In February 2024, the laying of the submarine high-voltage cable for the Lavrio - Serifos interconnection was completed. In May 2024 the laying of the submarine high - voltage cable for the Serifos - Milos interconnection was also completed.

The protection work for both submarine interconnections were completed in July 2024.

In February 2025 the laying of the submarine high-voltage cable for the Milos - Folegandros interconnection and the Folegandros - Thira interconnection were completed. The protection of both submarine interconnections has been completed in June 2025. The completion of the Cyclades interconnection will enable the development of RES plants with a total capacity of 332 MW on the islands, achieving a more stable, green and economical energy mix for the island complex.

The project is co-financed by the Recovery and Resilience Fund "Greece 2.0" with funding from the European Union Next Generation EU and by the Government Gazette No 494 4/8/2022 was characterized as a project of general importance for the economy of the country.

Eastern Peloponnese Corridor

The sub-project of the Transmission Line 400 kV that will connect the existing Megalopolis EHV Substation with the new Corinth EHV Substation was completed and put into operation in December 2022. In December 2023, the contract of the subproject of the new Transmission Line connecting the Corinth EHV Substation to the Koumoundourou EHV Substation was signed, putting the second part of the project in construction phase.

The completion of this sub-project is expected in the first half of 2026. The project of the Transmission Line "Koumoundourou EHV Substation – Corinth EHV Substation" is co-financed by the Recovery and Resilience Fund "Greece 2. 0" with the funding of the European Union's Next Generation EU and by the Government Gazette No 494 4/8/2022 was characterized as a project of general importance for the economy of the country.

Upgrading of the Koumoundourou EHV Substation

- FINANCIAL RESULTS FOR THE FIRST HALF 2024

The construction process of the new gas-insulated (GIS) Koumoundourou EHV Substation, which will replace the existing airinsulated EHV Substation, is in progress. The implementation of the new Koumoundourou EHV Substation will serve the connection of the 400 kV Eastern Peloponnese Corridor, will be the terminal of the Attica-Crete interconnection with the mainland grid and will enhance the reliability of the supply of loads (mainly in Western) Attica. The project is co-financed by the Recovery and Resilience Fund, as part of the Megalopolis – Corinth - Koumoundourou EHV Substation Transmission Line. The 400KV side (Phase A) was completed in February 2024 and test electrification was achieved in August 2024. The upgraded Koumoundourou EHV Substation is expected to be finalized in the first half of 2026.

The project is co-financed by the Recovery and Resilience Fund "Greece 2.0" with funding from the European Union's instrument Next Generation EU.

Dodecanese and Northeast Aegean islands' electrical interconnections

Kos, Rhodes and Karpathos will be connected to the mainland grid, with the Dodecanese electrical interconnection, via Corinth, in two phases. Accordingly, the Northeastern Aegean interconnection will include the islands of Limnos, Lesvos, Skyros, Chios and Samos, and will be implemented in three phases. The Dodecanese islands interconnection is included in the contract of the relevant Ministry for co-financing from the Islands' Decarbonization Fund. The marine surveys for both interconnections, Dodecanese and Northeastern Aegean, were completed in December 2024.

In April 2024, the call for expressions of interest of Phase A' of the Framework Agreement was posted, which concerns the submission of participation applications for the cable interconnections of the two projects, which was completed in July. Phase B, which concerns the submission of technical and economic offer from the contractors who have been approved during Phase A, was submitted in October 2024 and is in progress.

The tender for the section of the Dodecanese Interconnection project concerning the Korinthos and Kos Converter Stations, as well as the Korinthos–Kos High-Voltage Direct Current (HVDC) cable interconnection, was published at the end of 2024. The tender process for the Converter Stations is ongoing, while the tender for the Korinthos–Kos HVDC cable interconnection was declared unsuccessful due to the absence of bids and will be re-tendered.

In parallel, the Environmental Impact Assessment (EIA) for the Dodecanese interconnection was submitted to the Ministry of Environment and Energy in December 2023, and the issuance of the environmental assessment approval is expected. For the Northeastern Aegean interconnection, the EIA for the section from N.Santa (EHV S/S N. Santas) to Western Lesvos substation was posted for public consultation on the Electronic Environmental Registry (EER) in December 2024. The EIA for the section of the 150kV overhead transmission line from Western Lesvos substation to Mytilene substation, and up to the new Mytilene substation, is scheduled to be posted during the first semester of 2026.

In the meantime, with the licensing process, the collection of all the required cadastral data of the areas from the local services, which are to be expropriated for the construction of the projects, has commenced and is in progress.

ROUF EHV Substation

The development of the new Rouf EHV substation in the central Athens area will contribute decisively to the supply of the Attica basin. The new Rouf EHV substation is planned to be connected to the 400 kV System with the Koumoundouros and Acharnes substations with underground cables. For the connection to the 150 kV System, all 150 kV underground lines that are connected to the existing Rouf Substation to date, will be connected to the 150 kV side of the Rouf EHV Substation after its completion. The connection scheme of Rouf EHV Substation will provide the possibility of dismantling the 150 kV overhead lines from Koumoundouros substation to Rouf (3 double circuits), as well as the diversion of the 2B/150 transmission line Rouf - Schimatari to Koumoundouros, with the simultaneous dismantling of the section of the aforementioned transmission line.

The technical studies for the underground lines are currently in progress, in collaboration with the involved Municipalities and other relevant bodies. At the same time, the evacuation of buildings in the surrounding area of the existing Substation is underway, along with the necessary demolitions. The tender for the new Rouf GIS Substation is expected to be launched by the end of 2025.

APPENDIX A – ALTERNATIVE PERFORMANCE INDICATORS

In the context of the implementation of "Alternative Performance Measures" guidelines of the European Securities and Markets Authority (ESMA/2015 /1415el) applicable as of 3 rd July 2016 to the "Alternative Performance Measures" ("APM"), the Group uses "Alternative Performance Measures" ("APM") in the decision-making framework on financial, operational and strategic planning as well as for the evaluation and publication of its performance. The "APM's" serve to a better understanding of the financial and operational results of the IPTO Group and IPTO S.A. and its financial position. Alternative Performance Measures should always be considered in conjunction with the financial results, prepared under IFRS, and not to replace them. The following measures are used to describe the IPTO Group's and the IPTO S.A. performance:

EBIΤ (Earnings before interest and tax)

EBIT is used for the best analysis of IPTO Group's and IPTO's S.A. operating results and is calculated as follows: Total revenue minus total expenses. The EBIT margin (%) is calculated by dividing EBIT by the total revenue.

Adjusted EBIT

Adjusted EBIT is defined as published EBIT adjusted by a) provisions (including provisions for litigations and trade receivables), b) valuation losses (impairments) of tangible assets and, c) non-recurring items.

EBITDA (Earnings before interest, tax, depreciation and amortization)

EBITDA is used for the best analysis of IPTO Group's and IPTO's S.A. operating results and is calculated as follows: Total revenue minus total expenses before depreciation and amortization and valuation losses (impairments) of tangible assets. The EBITDA margin (%) is calculated by dividing the EBITDA by the total revenue.

Adjusted EBITDA

Adjusted EBITDA is defined as published EBITDA adjusted by the effect of a) provisions (including provisions for litigations and trade receivables), b) valuation losses (impairments) of tangible assets and c) non-recurring items.

Adjusted earnings before tax

Adjusted earnings before tax is defined as published earnings before tax adjusted by a) provisions (including provisions for litigations and trade receivables), b) valuation losses (impairments) of tangible assets, c) non-recurring items and d) non-recurring financial income/expenses.

Adjusted net income

Adjusted net income is defined as published Group net income adjusted by a) provisions (including provisions for litigations and trade receivables), b) valuation losses (impairments) of tangible assets, c) non-recurring items and d) non-recurring financial income/ expenses.

Net debt/EBITDA

The ratio reflects how earnings before interest, tax, depreciation and amortization of the IPTO Group and the IPTO S.A. cover net debt (as defined in the following paragraph).

Net debt

Net debt is defined asthe IPTO Group and the IPTO S.A. debt (current and non-current portion of debt, including finance lease liabilities) minus cash and cash equivalents and indicates the level of liquidity as well as the ability of the Group and the IPTO S.A. to repay the interest.

Return on Equity

This ratio shows how efficiently the IPTO Group and IPTO S.A. used its net assets to generate additional profits and is calculated as follows: Profit before tax divided by equity.

The calculation of the above rates (except for Alternative Performance Measures) directly derived from the Statement of Financial Position and Income Statement.

The following tables analyze the calculation ofselected Alternative Performance Measures:
