FINANCIAL STATEMENTS 208

Dear all,

In 2025, our targeted efforts were focused on strengthening infrastructure, competencies, and organizational resilience. We opened the year with the selection of a new Company's CEO, where Nemunas Biknius was appointed.. This gave an opportunity to continue with the planned strategic directions.

Particular attention is paid to the security of the main gas pipeline. We have performed internal diagnostics and spearheaded long-term solutions, ensuring sound operation of the gas transmission system in the future. The incident at the Pabradė Training Area in the spring proves the relevance of reinforcing prevention, and enhancing public and institutional relations to avoid undue risks posed by activities near the infrastructure.

Proceeding with further infrastructure modernization, we have opened a new System Control Centre, signed a contract for the electrification of the Jauniūnai Compressor Station, and have launched the procurement of the reconstruction of the Panevėžys Gas Compressor Station. We have engaged in a dialogue with the regulator on relining critical gas pipeline sections as required to ensure the reliability of the system.

For the first time, Amber Grid has prepared and presented a network optimization plan to the Board, and has initiated joint electricity, gas, and hydrogen system development scenarios as the basis for ten-year development plans. Our aim is to ensure effective use and development of transmission system meeting the actual needs for both, Lithuania and the region.

The completed sale of GET Baltic is also worth mentioning. From now on, Baltic gas suppliers form an integral part of a single trading system, the European Energy Exchange AG. This has strengthened gas market integration and improved regional competitiveness.

We have kept our efforts continued our focus on green gas, progressing to the next phase of the Hydrogen Corridor and initiating technical and economic feasibility studies, financially supported by the European Union. The Company is strengthening its excellence in green hydrogen and synthetic fuels, and has carried out and published an analysis of the potential for synthetic fuel production, export and storage. To make decisions driven by market demand and trends, we conduct market surveys on a regular basis. We also observe the upwards trend in the biomethane sector, while the connection to the AIB Hub has paved the way for further green gas development and opened up international biomethane trading opportunities.

We continue to extend our support to Ukraine: 55 vehicles and 4 generators were handed over to Ukrainian emergency services in 2025. From the outbreak of large-scale war in 2022, we have provided support and humanitarian assistance to Ukraine for EUR 172 thousand.

Looking ahead to 2026 and beyond, we see definite trends. Gas consumption in Lithuania does not show any decrease, marking the start of the year with new record-high consumption and transmission levels. Cold spells further underscored the importance of gas infrastructure for the Lithuanian and European economy and resilience.

We will maintain the Company's focus on strengthening the resilience of the system by investing in physical and cyber security, business continuity plans, and employee professional development. Occupational safety and competency building also remains a priority.

I thank all - employees, management personnel and the Board for the trust and joint efforts. Through consistent implementation of the Amber Grid's Strategy, we continue to strengthen the Company as a solid pillar of the

energy system and an active player in the development of green gas and new technologies.

Yours faithfully,

Chairman of the Board of Amber Grid Paulius Butkus

Dear colleagues, partners and customers,

In this Amber Grid Integrated Annual Report, we present a comprehensive overview of the year 2025 - our operating principles, values, key operational and financial indicators, and the strategic directions we continue to pursue.

The past year was marked by significant structural changes in the national gas sector. Although overall gas consumption in Lithuania decreased due to lower demand from the fertilizer industry, international gas flows increased, further strengthening the strategic importance of our system: gas flows to Latvia and Poland grew substantially, while export volumes were driven by rising demand in Ukraine.

Imports through the Klaipėda LNG terminal reached 30.5 TWh, enabling an increase in international flows. Gas flows to Latvia grew by nearly one-third, and to Poland - almost twofold. The latter increase was driven by the opportunity to redirect part of the gas to meet newly emerging demand in Ukraine. Overall, international gas flows grew by 15 percent last year. In the coming years, we aim to fully leverage the system's potential by attracting new clients from across Europe.

In 2025, we completed the strategic process launched in early 2023 - the transfer of GET Baltic shares to our partner, European Energy Exchange AG (EEX). The integration of GET Baltic into one of Europe's largest energy exchanges strengthened regional market liquidity, increased competition, and provided market participants with access to more advanced trading tools and a broader range of services. This is an important step for the development of the gas markets in Lithuania, Latvia, Estonia and Finland.

The geopolitical situation remains tense, so we place particular emphasis on the safety and reliability of the gas transmission system. Energy security is the foundation of the country's sustainable development. We continuously carry out technical inspections, maintenance and restoration works, and business resilience remains a priority in our daily operations. Last year, for the first time, we held national-level complex emergency exercises at the Jauniūnai gas compressor station, where together with responsible institutions we tested preparedness for extreme and hybrid incident scenarios.

The year was also important for hydrogen-related legislation. A working group of the Ministry of Energy began drafting the Hydrogen Law and amendments to energy legislation, transposing EU directives and creating conditions for the development of the hydrogen market and infrastructure. The draft outlines a clear framework for sector organisation, licensing, network development and compensation, and includes the necessary legal analysis for hydrogen network design and construction. Parliamentary deliberations are planned for the spring - a significant step in Lithuania's energy transition and the strengthening of the green economy.

In 2026, we will devote considerable attention to preparing secondary legislation on network operation, installation and protection, and we will participate in the development of the EU Network Package, which will accelerate the expansion of cross-border energy networks, reduce administrative burdens and enable financing for critical infrastructure security and resilience.

Another important direction is the biomethane market. Five biomethane producers are already connected to Lithuania's transmission system, one to the distribution system, and nine more are preparing to connect within the next couple of years. In 2025, around 277 GWh of biomethane was injected into the transmission and distribution systems, and by 2028 injection volumes are expected to reach approximately 815 GWh. Trade and investment will be

further stimulated by Lithuania's 2025 accession to the international biomethane guarantees of origin trading platform.

With increasing attention to sustainable operations, Amber Grid has begun monitoring a broader range of sustainability indicators. We aim to adhere to the highest sustainability governance standards so that these principles are not only declared but genuinely integrated into strategic decisions and daily activities. We prepare our sustainability report voluntarily, seeking to align as closely as possible with European sustainability reporting standards.

These ambitious goals cannot be achieved alone. That is why I highly value Amber Grid's membership in the EPSO-G group of companies. Together we can achieve far more than individually. Cooperation and synergy within the group bring significantly greater benefits than working in separate areas.

Looking back at 2025, I would like to sincerely thank the Amber Grid team for their dedication, professionalism and consistent work in the energy sector. I also thank our clients, partners and shareholders for their trust and cooperation. The year 2026 has already begun with new ideas, planned investments and necessary changes. As we pursue long-term goals, we are ready to seize emerging opportunities, overcome upcoming challenges and create value for both our clients and the state. I am confident that together we will be even stronger.

Sincerely, Nemunas Biknius CEO of Amber Grid

1. ‌Operating Environment and Regulatory Framework
   1. ‌Business environment and forecast

      Klaipėda LNG terminal continues to be the most important source of gas supply for Lithuania and the Baltic States.

      During 2025, 30.5 TWh of gas or 90.0% was supplied from the terminal, 2.6 TWh or 7.5% - from Latvia, 0.6 TWh or 1.7% - from Poland, and 0.3 TWh or 0.8% from biogas producers of total gas input. Klaipėda LNG terminal capacity is fully booked until 2033, i.e. each year, 33 TWh of its capacity will be allocated to the terminal's customers.

      The guarantees of origin were also issued for the biomethane which has been produced in Lithuania and fed into transmission network since the summer of 2023. By the end of 2023, 47 GWh of biomethane had been produced in Lithuania and fed into the Amber Grid's transmission system. During 2024 and 2025, 127 GWh and 277 GWh, respectively, had been fed into the natural gas transmission and distribution systems.

      In 2025, three biogas producer systems were connected to the Amber Grid's transmission network, and one to the natural gas distribution network.

      In pursuit of full energy independence from the Russian gas, and in response to Russia's blackmailing of Europe over energy and the outbreak of war in Ukraine, as of 1 April 2022, Lithuania has wean itself off Russian gas: the Lithuanian gas transmission system operates without imported Russian gas. Lithuania's entire gas demand is met through Klaipėda Liquefied Natural Gas (LNG) terminal, and Santaka entry point for gas from Poland, and Kiemėnai entry point for gas from Latvia.

      Gas is continued to be transported to the Kaliningrad Region by transit through Lithuania, however, in an unusual technical mode, which ensures transmission of gas only to the extent necessary for the transit.

      During 2025, 33.9 terawatt hours (TWh) of gas was supplied to Lithuania, excluding gas transported to the Kaliningrad Region. This was 14.6% more compared to the total quantity supplied in 2024,

      when 29.6 TWh of gas was transported to Lithuania. The pipeline connection to Latvia transported 12.7 TWh of gas for the needs of other Baltic States and Finland, which is by 31.3% more than 10.0

      TWh transported towards the Baltic States in 2024. The pipeline connection to Poland transported 5.0 TWh of gas, which was 95.0% more compared to 2.5 TWh transported towards Poland in 2024.

      Decrease in gas consumption in Lithuania in 2025 was marginal. In total 15.9 TWh of gas was consumed in Lithuania during 2025, which was 6.2% less than 16.9 TWh of gas demand in 2024.

      More stringent EU environmental policy requirements introduced in the context of combating climate change, promotion and development of renewable energy sources, and more efficient use of energy will reduce consumption of natural gas for both energetic and industrial domestic needs. However, due to the limited number of alternatives in some of the industries and segments of the transport sector, and due to competitiveness while rendering balancing, reservation services in the heat and electricity sectors, natural gas will play an important role as a transitional source of energy in pursuance of pan-European and national goals to reduce greenhouse gas emissions. At the same time, gas transported via the pipelines will face changes, with green gas making up an increasing share: biomethane and gas generated through the process of conversion of green electricity -green hydrogen and synthetic methane.

      On 28 June 2024, the Parliament (Seimas) of the Republic of Lithuania adopted the resolution on the Approval of the National Climate Change Management Agenda Regarding the National Energy Independence Strategy (NEIS). In its NEIS, Lithuania has set ambitious goals that will contribute significantly to the implementation of the United Nations' 2030 Agenda for Sustainable Development, and implementation of the goals set forth in the Paris Agreement, and the goals set forth in the EU's 2030 Climate and Energy Framework. They aim to increase the share of renewable energy sources (including biomethane and other RES-produced gas) in the country's total final energy consumption. The Law on Energy from Renewable Sources of the Republic of Lithuania sets a target of at least 55% of renewable energy sources in the country's total final energy consumption by 2030, with a further increase in this share.

      In Lithuania, similarly as in the EU, it is expected that natural gas will continue to play an important role in the energy mix at the time of transition to a low-carbon economy. The domestic annual demand for natural gas will reach around 17 TWh by 2030, of which more than 50% will represent demand for gas as a raw material in the fertilizer production industry.

      There is an urgency to transform Europe's energy system:

      In response to the difficulties and disruptions in the global energy market caused by Russia's invasion of Ukraine, the European Commission (EC) launched the RePowerEU plan in 2022 to gradually phase out Russian fossil fuel imports.

      As foreseen in the REPowerEU Plan, the objectives will be pursued by:

      • energy savings,

      • diversification of energy supplies,

      • accelerated roll-out of renewable energy

      The gas sector and networks can effectively contribute to the creation and development of the European hydrogen economy as envisaged in the EU Hydrogen Strategy. The European Commission envisages two phases - the transition period until 2030 and the period until the hydrogen market is established in 2050.

      On 13 June 2024, the hydrogen and gas decarbonisation package was adopted (hereinafter the "Gas Package"). The Package comprises a Regulation and a Directive. The aim of the initiative of the proposals stipulated in the Directive and the Regulation is to facilitate the integration of renewable and low-carbon gas, particularly hydrogen and biomethane, into the energy system. The objective is a 55% reduction in methane emissions compared to 1990 by 2030 and the achievement of the climate-neural economy in the EU by 2050.

      One of the main objectives of the Gas Package is to create the hydrogen market, develop a proper environment for investments and facilitate the development of the related infrastructure and trade with the third parties. Firstly, the access to the hydrogen infrastructure, segregation of the hydrogen production and transport activities and setting the tariffs will be governed by the market rules.

      The year 2025 was dedicated to transposing the provisions of the Gas Package into Lithuanian legislation. The inter-institutional working group established by the Minister of Energy prepared the draft Law on Hydrogen and Law on Electricity, which were published at the end of the year for comments from the stakeholders.

      On 13 June 2024, the EU regulation on the reduction of methane emissions in the energy sector was adopted and officially entered into force on 5 August 2024. The requirements in this Regulation aim to increase the transparency of imports of fossil energy (e.g. natural gas, oil and coal) into the EU, promote the wider application of measures to reduce methane emissions in the energy sector, and harmonize comprehensive standards for the measurement, reporting and verification (MRV) of methane emissions and guidelines. The requirements of this Regulation will have a great impact on the organization of the Company's activities.

      On December 10, 2025, the European Commission published the EU Grid Package. It presents proposals aimed at promoting investments in networks, accelerating permitting procedures for infrastructure development projects, and improving coordination of network planning at the EU level. Significant attention is given to the resilience and security of energy networks. Member States are currently submitting their positions on the package.

   2. ‌Regulatory environment

      In December 2024, the public consultation initiated by NERC on the principles of the pricing methodology applicable from the 2026 tariff period was closed on 14 February 2025.

      In May 2025, taking into account the results of the finalised public consultation, NERC updated the Methodology for Determining Revenue From and Prices for Regulated Natural Gas Transmission Activities. The updated methodology also considers the implementation of the provisions of the Regulation on Decarbonisation announced during the public consultation, which provides for a 100% discount to be applied to the internal entry point, i.e. the point for entry of green gas (biogas, hydrogen) into the transmission system.

      The updated methodology will be applicable from the 2026 tarif period. There were no other significant changes in the regulatory framework in 2025.

Describing 2035 success: value proposition for stakeholders

Below is an overview of the implementation of the Company's Strategy to 2035 set for 2025.

In implementing our mission and pursuing our vision, we highlight three fundamental commitments, which we refer to as key business directions for implementing strategic changes. We have also supplemented these directions with the commitment of enabling sustainable and effective progress with the aim of implementing the Strategy.

The key directions were used as the basis for defining objectives, measures and strategic performance indicators within a short-term horizon of three years.

Implementation of the mission, pursuit of the vision and all activities of the Company are based on the fundamental human and professional values: we are open, responsible and reliable.

Map of strategic directions, goals and key indicators to 2035

In pursuit of its goals, Amber Grid continuously evaluates the implementation and progress of the Strategy. A detailed information on the Company's strategy is available on the Company's website at Strategy I Amber Grid.

The following represents the status of implementation of the strategy set for 2025.

Implementation of the Company's strategy

No precise strategic measurement indicators are set for strategic objectives "Gas network optimisation, considering gas consumption needs and security", "Strengthen national security", and "Develop progressive business environment", as the nature of their activities leaves no choice in setting long-term, measurable, comprehensive indicators, therefore they are addressed through the specific measures.

1. 1. ‌Operating and financial objectives

      The Board of Amber Grid set and approved the annual operating objectives to be implemented by the Company in 2025.

      Based on the Board's assessment, the objectives set for the Company for 2025 were achieved at 88.5%

   2. ‌10-year network development plan

      In January 2026, Amber Grid updated its strategy, which outlines significant investments in the renewal of existing infrastructure and the development of new infrastructure. To properly plan infrastructure needs and the investments required to meet them, and following best practices, in 2026 for the first time Litgrid and Amber Grid carried out a public consultation on a joint development scenario for electricity, gas, and hydrogen networks. During the consultation, planned investment projects and their preliminary values were also presented. The proposals and comments received from market participants are currently being analysed and coordinated with stakeholders; the assessment will be made public. Based on the agreed development scenario for electricity, gas, and hydrogen networks, the transmission system operators' network development plans will be updated, with publication planned for early in the second half of 2026. Below are the network development plans prepared in 2024 and valid in 2025, which are currently being updated.

      In accordance with the provisions of the Natural Gas Act, Amber Grid prepares a ten-year transmission system operator network development plan every two years. The currently valid plan is the ten-year (2024-2033) network development plan prepared by Amber Grid in 2024, which was approved by the National Energy Regulatory Council (VERT) in October 2024. The main aspects of Amber Grid's ten-year network development plan include:

      • modernisation of existing gas infrastructure elements, ensuring security and increasing resilience to crisis situations,

      • development of alternative energy sources and integration of renewable energy,

      • creation of a hydrogen transmission network and synergy between the gas and electricity sectors,

      • reduction of greenhouse gas (GHG) emissions.

      One of the commitments highlighted in the plan is the modernisation of the national gas transmission infrastructure, taking into account Lithuania's energy independence goals, European energy and decarbonisation policies, and the needs of green energy project developers and market participants. Considerable attention is given to the integration and diversification of renewable energy sources (RES), including biomethane and green hydrogen. When preparing the integrated hydrogen network plan within the ten-year network development plan, the needs of potential customers were taken into account. Possible network solutions were coordinated with the electricity transmission system operator Litgrid and its network development plans.

      Key investment projects implemented by the Company in 2025 were as follows:

      A project to rebuild sections of the main gas pipeline (due to non-compliance with local class requirements) has been launched and will continue in 2026. During the project, separate sections of the gas pipeline are planned to be rebuilt in several locations in Lithuania to meet the requirements for higher area classes, thereby improving their safety. The value of the project is more than EUR 10 million;

      The project for the reconstruction of the Jauniūnai gas compressor station (GCS), which will continue in 2026. Following the project, the reliability of GCS will be optimized by installing an electrically powered compressor. The value of the project is EUR 30.9 million;

      The reconstruction of the Elektrėnai gas distribution station (DSS). The project will continue in 2026 and envisages the renovation of the GDS by installing new technological equipment. The value of the project is EUR 2.1 million;

      The project preparatory work for the reconstruction of the Panevėžys gas compressor station has been initiated. During the project, new compressor units are planned to be installed to comply with environmental requirements.

   3. ‌Market for the services provided

      Amber Grid provides natural gas transmission services to the system users, other operators, biogas producers and gas market participants in the territory of Lithuania: it transmits gas to the domestic consumers, also transports natural gas to Latvia, Poland and transit to the Kaliningrad Region of the Russian Federation. Gas is supplied to the system via the LNG terminal in Klaipėda and gas entry points from Latvia, Poland and for the transit needs from Belarus. As of the summer 2023, the biomethane produced in Lithuania has also been injected into the transmission system. With effect from 1 April 2022, gas supply for domestic consumption was discontinued from Russia.

      Amber Grid is also responsible for balancing gas flows in the transmission system and administering the Klaipėda LNG terminal, its infrastructure, installation of the interconnector and the funds (LNGT funds) to compensate for fixed operating costs and the nominated supplier's reasonable costs of supplying the necessary volume of liquefied natural gas. The Company actively works with its partners to create conditions for efficient functioning of the natural gas market by increasing the competitiveness and liquidity of the gas market and by ensuring attractive conditions for customers to operate in the natural gas market.

      Amber Grid administers the National Register of Guarantees of Origin for gas produced from renewable energy sources, i.e. fulfils the following functions: issuance, transfer and cancellation of the guarantees of origin, supervision and monitoring of the use of the guarantees of origin, and recognition of the guarantees of origin issued in other states as acceptable in Lithuania. Green gas is produced from biomass and other RES. The guarantee of origin is granted per unit of energy: one megawatt-hour (MWh) supplied to the gas transmission and distribution network. The guarantee of origin system enables identification, registration and monitoring of the biomethane produced, while the end-users of such fuel can be assured that the gas they use is produced from renewable energy sources.

   4. ‌Customers

      The customers of Amber Grid's services of natural gas transmission via gas transmission pipelines and balancing of natural gas flows in the transmission system are large Lithuanian electricity and district heating companies, industrial and medium-size businesses in Lithuania, energy and natural gas supply companies in the Baltic and third countries that receive natural gas transmission services.

      At the end of 2022 and H1 2023, the Company received a number of requests from biomethane producers for the issuance of preliminary connection conditions, following the adoption of amendments to Article 32 of the Law of the Republic of Lithuania on Renewable Energy Resources in 2022, which entered into force on 1 November 2022, which provide that a biogas producer, after coordinating with the gas system operator, shall have the right to design and/or construct / install and perform works in the gas system on behalf of the gas system operator, according to the procedure, terms and conditions set out in the gas system service agreement for connection of the biogas production facilities to the gas system.

      The new legal framework has significantly boosted the initiatives of biogas producers to connect to Amber Grid's gas transmission system. More information thereon is available in the Section "Green gas activities".

      1. Gas transmission Gas transmission quantities

         In 2025, 30540 GWh of natural gas was injected into Amber Grid's gas transmission system from Klaipėda LNG terminal for consumers of Lithuania and EU Member States; 2552 GWh was transported from Latvia to Lithuania and 565 GWh - from Poland

         to Lithuania. In 2025, 277 GWh of biomethane had been produced in Lithuania and injected into the transmission system in Lithuania. Klaipėda LNG terminal supplied 90.0% of the total required quantity of gas for consumers of Lithuania and EU Member States.

         In 2025, 15901 GWh of gas was transported through the domestic exit point for the gas consumers in Lithuania. Compared to 16947 GWh of gas transported during 2024, gas transmission quantities decreased by 6.2%.

         In 2025, 12,718 GWh of gas was transported from the Lithuanian transmission system to Latvia through the Kiemėnai gas metering station, i.e. 31.3% more than in 2024 (9,688 GWh).

         In 2025, 4,969 GWh of gas was transported from Lithuania to Poland via Santaka gas metering station, i.e. 95.0% more than in 2024 (2,548 GWh).

         During the reporting period, 19727 GWh of gas was transported to the Kaliningrad Region of the Russian Federation (2024: 26125 GWh).

         As at 31 December 2025, the Company had 97 agreements on natural gas transmission services with the transmission system users (gas consumers, gas distribution system operators, importers, gas suppliers supplying gas up to the consumer systems), of which 73 system users used the transmission capacity during the reporting period. The Company had 1 natural gas balancing agreement with the market participants trading natural gas via the virtual trading point, but not transporting it via the transmission system.

         Regulation of prices for the gas transmission system operator's services

         The network code on harmonised transmission tariff structures for gas (TAR NC) set by the European Commission Regulation (EU) 2017/460 of 16 March 2017 has been applied to pricing of transmission services since 2020.

         Regulation of gas transmission prices is conducted by NERC through setting the revenue cap, the pricing methodology, and through approval of the specific prices set by the Company. The revenue caps for regulated activities can be annually adjusted by the decision of NERC in accordance with the procedure established in the Methodology for determining revenue from and prices for regulated natural gas transmission activities.

         A 5-year regulatory period, which started in 2024, will end at the end of 2028. The revenue cap set by NERC for the regulated activity for 2025 was EUR 63.83 million (by 4.75% lower than the one set for 2024, which was EUR 67.01 million). In April 2025, NERC set a revenue cap of 82.95 million euros for the gas transmission system operator Amber Grid for the year 2026, which is 30% higher than in 2025. Compared to 2025, regulated costs in all categories will increase by a total of ~10% in 2026 due to inflation and investments made. The final part of compensation to the Polish gas transmission system operator, which increases costs by ~3%, has also been included for the implemented Lithuania-Poland interconnection project of common interest. The estimated deviations in revenue, costs and return on investment for previous periods are another significant reason for the increase in the revenue ceiling (~17%).

         At the beginning of 2025, when setting the transmission tariffs for 2025, 64.4 TWh of natural gas was forecast to be transported through the Lithuanian gas transmission system, which is 1.4% less than the estimate for 2025 (65.3 TWh) and 16.5% more than the actual transport in 2025 (55.3 TWh). It is forecasted that Lithuanian gas consumption will decrease by 1.1% next year: from

         16.9 TWh, which were estimated when setting prices for 2025, to 16.7 TWh calculated for 2026.

         The prices were set taking into account the regulatory revenue cap approved by NERC and the approved changes to the methodology applicable to the calculation of transmission service prices from 2026. The average price of gas transmission services for Lithuanian consumers in 2026 will be 1.52 EUR/MWh. This is 5% less than the gas transmission price valid in 2025, which was 1.60 EUR/MWh. In 2025, at all gas entry points, including the Klaipėda entry point, transmission service prices were standardised and aligned with the entry prices applied in the neighbouring tariff zone of Latvia, Estonia and Finland. The same pricing approach is maintained in 2026. In addition, as of 2026, a 100% discount will apply at the connection point of the Lithuanian transmission system with biogas production facilities.

         Detailed information on the prices of gas transmission services is available on Amber Grid's website.

      2. Balancing of gas flows in the transmission system

         Amber Grid ensures the balancing of natural gas flows in the transmission system. By following the Rules for Natural Gas Transmission System Balancing, the Company purchases balancing gas from a gas market participant when there occurs gas surplus in the transmission system, and the Company sells balancing gas to a gas market participant when there occurs gas shortage in the transmission system.

         The Rules for Balancing the Natural Gas Transmission System enforced on 1 March 2022 stipulate that the virtual trading point cannot trade in day-ahead products, which has increased the number of market participants causing imbalances. The Transmission system operator calculates a neutrality fee for each market participant to ensure financial neutrality for the reporting period. The amendments have been drafted in accordance with the provisions of Commission Regulation (EU) No 312/2014 of 26 March 2014 establishing a Network Code on Gas Balancing of Transmission Networks.

         During 2025, due to the imbalance caused by the system users, the Company bought 633.1 GWh and sold 478.4 GWh of gas.

         Following the amendments to Amber Grid's Rules for Balancing the Natural Gas Transmission System rules enforced on 1 March 2022, Amber Grid calculates a neutrality fee for market participants to ensure financial neutrality. In 2025, EUR 4.7 million was refunded to system users and EUR 0.1 million was collected from them.

         Transmission of gas by transit from/to third countries causes mixing of physical gas flows in the transmission system, which in turn results in a difference between the gross calorific value of gas at the entry and exit points of the gas transmission system. In 2025, the gas transmission to the Kaliningrad Region resulted in a difference of 225.1 GWh at the entry and exit points of the transmission system, which was bought from the Company through the settlement of the third country to third country transmission services provided.

         Apart from balancing of gas flows of the system users and other gas market participants, the quantity of natural gas contained in the pipelines of the Company's transmission system fluctuates due to technical and technological characteristics of the transmission system.

      3. Administration of funds intended for compensation of construction costs and fixed operating costs of the LNG terminal, its infrastructure and the connector, and for compensation of reasonable costs incurred by the designated supplier.

         In order to ensure compliance with the requirements of the legal acts (the Law on Liquefied Natural Gas Terminal and the supplementing legal acts), the Company collects, administers and pays out the LNGT funds to their payers in accordance with the procedure prescribed by laws. These funds are used to compensate Amber Grid for the costs of administration of the LNGT funds.

         The security component set for 2025 is EUR -25.55/ MWh/ day/ year (in accordance with Resolution No O3E-1469 of NERC of 27 November 2024). It applied from 1 January to 30 June 2025. The security component set for 2025 was EUR -43.00/ MWh/ day/ year (in accordance with Resolution No O3E-791 of NERC of 29 May 2025). It applied from 1 July to 31 December 2025. Acting as the administrator of the LNGT funds and in accordance with the description of the procedure for the administration of the LNGT funds, as amended by NERC, the Company will have to repay the LNGT funds to their payers (transmission system users) in 2025.

         The proportions of the allocation of LNGT funds applicable to their beneficiaries (applied in 2023 and as of 1 January 2024, respectively) and agreed with NERC, are presented in Table. Additionally, the proportions of the allocation of LNGT funds applicable to their beneficiaries and agreed with NERC, effective as of 1 January 2025, are presented in Table.

         By the decision of Kaunas Regional Court of 20 January 2022, the proceedings were suspended in respect of the claimed LNGT extra charges of EUR 4,678 thousand and late interest of EUR 55 thousand arising from the natural gas transmission service contract of 22 December 2014, as it was pending the decision of the European Commission regarding the compatibility of the LNGT extra charges, collected during the period from 1 January 2016 to 31 December 2018, with the state aid rules under the EU law. By decision of 17 March 2022, the Lithuanian Court of Appeal left the decision of Kaunas Regional Court of 20 January 2022 unchanged.

         By the decision of the Kaunas Regional Court of 20 September 2022, the proceedings concerning late interest of EUR 763 thousand under the natural gas transmission service contract of 21 December 2012, as well as AB Achema's counterclaim challenging the calculation of late interest and the allocation of payments, were suspended pending a decision of the European Commission on the compatibility of LNG terminal funds during the period from 1 January 2016 to 31 December 2018, with the state aid rules under the EU law. The Company appealed this decision; however, by its ruling of 8 September 2022, the Lithuanian Court of Appeal upheld the decision of the Kaunas Regional Court. As the European Commission has not yet adopted a decision, the proceedings remain stayed.

         On 8 August 2025, the Company submitted a statement to the Kaunas District Court regarding the increase of the claim (hereinafter the "Statement"), asking the court to award EUR 763,119.55 of default interest from Achema AB in favour of the Company based on the natural gas transmission service contract dated 21 December 2012, EUR 7,510,828.66 of LNG extra charges and EUR 640,180.35 of default interest under the natural gas transmission service contract dated 22 December 2014. The issue of acceptance of the Company's Statement will be decided by the Kaunas District Court after resuming the proceedings.

Guidelines for hydrogen development in Lithuania in 2024-2050

The Guidelines for Hydrogen Development in Lithuania 2024-2050 (hereinafter - H2 Guidelines) were approved by Order No 1-81 of the Minister of Energy of the Republic of Lithuania of 26 April 2024. The H2 Guidelines set out a vision for hydrogen development in Lithuania, defining strategic directions and stages of hydrogen development, the business environment and challenges The H2 Guidelines document identifies the hydrogen network from Finland to Germany as one of the main hydrogen transport projects, which will run through Lithuania and will enable the export or import of hydrogen from other EU countries. The implementation of this project will allow Lithuania to benefit from underground hydrogen storage facilities planned in other Member States. Hydrogen blending in the natural gas network is identified in the H2 Guidelines as a transitional measure to stimulate the emergence of a green hydrogen market and to create the first hydrogen transport capacities. In order to exploit the potential of green hydrogen and its derivatives in the Lithuanian economy and export markets, at least one hydrogen valley is planned to be established in the first stage, later increasing this number to two. According to the H2 Guidelines, the installation of a 1.3 GW electrolysis plant in Lithuania would produce 129,000 tonnes of green hydrogen per year from 2030. Taking into account Lithuania's GHG reduction targets and its international commitments, it is estimated that the demand for green hydrogen in Lithuania could reach 110,000 tonnes per year in 2030. In addition, around 33,000 tonnes could be available for export.

On 27 June 2024, the Seimas of the Republic of Lithuania approved the National Energy Independence Strategy, designed to implement fundamental changes in the energy sector, ensuring that the amount of energy produced in Lithuania matches the amount consumed and that the energy sector becomes completely climate-neutral by 2050.

In order to contribute more significantly to the promotion of hydrogen and Power-to-Gas technologies at local and regional level, the Company further participates in the Lithuanian Hydrogen Platform established by the Ministry of Energy, and is a member of the European Clean Hydrogen Alliance and the Lithuanian Hydrogen Energy Association. The Company has continued to participate in the European Hydrogen Backbone initiative, which brings together more than 30 transmission system operators from across Europe to develop a vision, analyse alternatives, and draw up implementation plans for a nationwide interconnected hydrogen transport/storage infrastructure.

Nordic-Baltic Hydrogen Corridor project

On 1 July 2025, the project promoters of the Nordic-Baltic Hydrogen Corridor (NBHC), Finland's "Gasgrid vetyverkot Oy", Estonia's "Elering", Latvia's "Conexus Baltic Grid", Lithuania's "Amber Grid", Poland's "GAZ-SYSTEM", Germany's "ONTRAS Gastransport", and the European Climate, Infrastructure and Environment Executive Agency (CINEA), signed an agreement for the European Union's (EU) financial support for the Nordic-Baltic Hydrogen Corridor. A maximum amount of EUR 6.8 million is earmarked for the feasibility study phase of the Nordic-Baltic Hydrogen Corridor

This collaboration reinforces the competitiveness of the Baltics in the hydrogen sector and confirms the project partners' commitment to both national and international hydrogen infrastructure development. The Corridor aims to support the development of clean hydrogen markets and integrate them into Europe's future energy system. The co-financing from the Connecting Europe Facility (CEF) for cross-border energy infrastructure projects under the Trans-European Networks for Energy (TEN-E) will allow NBHC project partners to conduct in-depth feasibility studies that examine the technical, economic, regulatory and environmental aspects of building a large-scale hydrogen pipeline network in the Baltic Sea region.

The NBHC represents a significant step towards building the European hydrogen backbone, a strategic vision for connecting hydrogen production and consumption across the continent. By supporting renewable hydrogen transmission, the corridor will enhance energy security, and accelerate Europe's transition to a decarbonised economy.

By 2040, the corridor is projected to transport up to 2.7 million tons (Mt) of renewable hydrogen annually between the countries. The pre-feasibility study indicated that the NBHC can be one of the first operational cross-border hydrogen pipelines in Europe. The NBHC pipeline is currently planned to be 1,200 mm in diameter, with several compressor stations and spanning approximately 2,500 km. The feasibility study phase, launched in 2025, is expected to be completed early in 2027. It will lay the groundwork for subsequent project development phases.

NBHC commissioning is expected around 2033.

• In December 2022, six gas transmission system operators, the project partners, signed a cooperation agreement on promoting the project together.

• In April 2024, the Nordic-Baltic Hydrogen Corridor was granted the status of the project of common interest (PCI) by the European Commission.

• In June 2024, the project partners completed a pre-feasibility study.

• In October 2024, transmission system operators applied for funding under the Connecting Europe Facility (CEF).

• In July 2025, the grant under CEF was allocated to the Nordic-Baltic Hydrogen Corridor.

• In December 2025, the Nordic-Baltic Hydrogen Corridor was included by the European Commission in the second list of Projects of Common Interest (PCI).

Development of biomethane production

As Lithuania's economy grows and the country moves towards achieving the European green energy transformation goals, there is a growing need to look for possibilities to utilize renewable energy resources in the country. Recently, the emergence of biogas and biomethane in the gas system has played one of the most significant roles in this context.

In Lithuania, investments in biomethane production is also growing rapidly. Large industrial companies and new entrants areactively exploring the possibility of installing biomethane plants, connecting them to the gas transmission and distribution system, and supplying the biomethane produced to the domestic and foreign markets through the Green Gas Guarantee of Origin (GO). The integration of biomethane into the common energy system is now a key energy objective for European countries, and is therefore a significant future opportunity for the Company's customers.

The Lithuanian government has recognised the potential of biomethane and has already implemented certain policy measures to support its development. For example, the Alternative Fuels Act sets ambitious goals for the use of renewable fuels in the transport sector, providing a strong incentive to build new biomethane plants. The government has allocated funds to support biomethane projects, demonstrating its commitment to transitioning to a more sustainable energy system.
