KEY ECONOMIC EVENTS IN 2025

• Almost all business segments achieved double-digit REVENUE growth in the first three months of the year compared to the base period, resulting in a 9% increase in ALTEO's revenues for Q1.

• As an unfavorable development, domestic wind power production reached its lowest level in the past five years due to unfavorable weather conditions, which significantly reduced the expected positive impact of new wind turbine capacity added last year.

• ALTEO intends to continue to exploit as many opportunities as are offered by the market in the period ahead. ALTEO's management considers the results of the major segments and business lines to be successful. We expect the weather effects to level off in the medium to long term, but at the same time to increase deviations between years and quarters as the renewable portfolio grows. Long-term value maximization remains the objective of management, which is not affected by fluctuations of this kind.

• ALTEO is continuing its active INVESTMENT ACTIVITY as outlined in its announced strategy, has further expanded and intends to further expand its renewable energy and waste management activity, completed significant acquisitions at the end of 2024, and actively started the largest greenfield investment project in its history with the development of an energy storage facility worth nearly HUF 21 billion. In addition, it continues to identify opportunities in the strategic cooperation between MOL and ALTEO.

• CONSOLIDATED EBITDA WAS HUF 3.6 BILLION, down from the previous year, mainly due to higher costs related to strategic growth, caused by the share-based remuneration scheme, which grew in line with the significant increase in the share price.

• THE CONSOLIDATED NET PROFIT WAS HUF 981 MILLION, down by HUF 1.6 billion from 2024, primarily due to depreciation caused by the larger asset portfolio, different interest rates and exchange rates.

KEY EVENTS IN 2025 TO DATE

• On January 9, 2025, ALTEO published its business strategy for 2025-2030, which will enable the Company to achieve a veritable LEAP IN SCALE, BOTH IN THE GEOGRAPHICAL AND FINANCIAL SENSE.
• On February 6, 2025, ALTEO signed the largest credit facility agreement in its history with MBH Bank Nyrt. and Gránit Bank Nyrt. Under the agreement, the financing parties provide ALTEO with a FACILITY OF UP TO HUF 40 BILLION for general corporate financing purposes. ALTEO intends to use the available facility TO IMPLEMENT ITS STRATEGY, to support its further growth and to optimize its financing structure.
• On March 10, 2025, ALTEO established a new, independent organizational unit to support its regional expansion, which started its operations under the direct supervision of Deputy CEO Magdolna Tokai.
• On April 17, 2025, ALTEO'S GREEN COMMITTEE ADOPTED A COMPREHENSIVE BIODIVERSITY STRATEGY. The 15-year strategy goes beyond site-related environmental activities: the Company is not only seeking to conserve and restore biodiversity in its own power plant areas, but is also planning proactive habitat restoration and water retention projects in areas away from the power plants.
• On April 28, 2025, the General Meeting ADOPTED ALTEO'S 2024 ANNUAL REPORT, Corporate Governance Report and Remuneration Report.
• The General Meeting resolved that the Company WOULD NOT PAY DIVIDEND AGAINST 2024, AND THAT THE PROFIT BE ALLOCATED TO RETAINED EARNINGS FOR THE IMPLEMENTATION OF ITS LONG-TERM STRATEGIC OBJECTIVES.
• The General Meeting ELECTED ATTILA LÁSZLÓ CHIKÁN AS A MEMBER OF THE COMPANY'S BOARD OF DIRECTORS from April 30, 2025 until April 30, 2030.

CONSOLIDATED STATEMENT OF PROFIT OR LOSS (IFRS)

Most important changes in operating profit and loss items:

• REVENUE: Almost all business segments achieved double-digit revenue growth, resulting in a 9% increase in ALTEO's revenues for Q1. Revenues increased due to growth in the scheduling and retail portfolio, changes in electricity prices on the world market and increased overall renewables-based production capacity, offset by less favorable weather

• MATERIAL EXPENSES: Overall, these expenses rose proportionate to revenue, in line with

• compared to last year.
• portfolio expansion and the rise in energy prices.

• PERSONNEL EXPENSES: The higher cost level was mainly driven by strong share-pricedependent cost increases for long-term incentive programs and, to a lesser extent, by the increase in staff headcount needed to support further growth.

• DEPRECIATION: Depreciation exceeds the level of the previous year, due to a larger asset portfolio and the acquisition of Mov-R in the last quarter of 2024.

• CAPITALIZED OWN PRODUCTION: The difference compared to the previous year is due to increased Company-implemented investment activities, mainly related to the ARTEMIS

system.

*In the opinion of the Company, the profit category that can most reliably be used to measure the profitability of the Group is EBITDA (a profit category from which financial items, taxes, depreciation, and non-systematic reductions, typically impairments, have been removed). Therefore, impairment and local business taxes and innovation contributions, if any, have been removed from the Other Revenues and Other Expenses lines that are used to provide a more detailed elaboration of the EBITDA in the above table.

EBITDA was down by HUF 860 million year-on-year, despite a HUF 2,331 million increase in revenue.

• FINANCIAL INCOME: The decrease was due to the result from exchange rate changes and lower

• interest income realized on lower cash holdings.
• mainly due to restructuring and higher revenue.

• INCOME TAXES: Despite the decrease in profit before taxes, income taxes increased slightly,

• NET PROFIT dropped compared to the base period, as a result of the above operational impacts.

• OTHER COMPREHENSIVE INCOME: ALTEO enters into hedging transactions in order to secure the purchase price of raw materials and, thereby, the profit content on heat and electricity sold at fixed prices, and to fix the interest rates on loans. Other comprehensive income includes the result of changes in the fair value of transactions as financial instruments that hedge the price of gas used to produce electricity at the time of setting the official heat prices and/or sold at fixed forward prices, the EUR/HUF exchange rate, and interest rate changes, until the real transaction is closed.

CONSOLIDATED STATEMENT OF FINANCIAL POSITION (IFRS)

• INVESTMENTS, CAPITAL EXPENDITURES: In line with the strategy, capacity expansion and efficiency-enhancing projects with significant investment needs are underway (including RRF energy storage projects, DRS – processing of waste subject to product charges),
• WORKING CAPITAL: Available liquid assets have been significantly reduced due to increased capital expenditures. The significant increase in other current assets was due to a rise in long-term deposits, reflecting the higher portfolio and volume. The decrease in trade payables and accruals was in line with the change of trade receivables and accruals. The increase in the portfolio of other short-term liabilities is due to the rise in VAT payable at Group-level, which is due to the amendment of legislation on reverse-charge taxation and has a timing effect, with no impact on profit.
• The portfolio of LONG-TERM LIABILITIES, SHORT-TERM LOANS decreased by the contractual repayments of loans, slightly offset by a surplus in other long-term liabilities due to the increase in the price of share-based benefits.

HEAT AND ELECTRICITY PRODUCTION AND MANAGEMENT

• The segment's REVENUE increased by 16% (HUF 2.55 billion) compared to the 2024 period, due to the growth in the scheduling portfolio and the change in electricity prices on the world market, partially mitigated by the decrease in price-capped heat tariff revenues. The increase in revenue was somewhat exceeded by the rise in MATERIAL EXPENSES, mainly due to the expansion of the external partner portfolio and higher energy prices. The difference relative to revenues is due to the change in EBITDA distribution between the various sub-segments and activities.
• The increase in CAPITALIZED OWN PRODUCTION is caused by the ramp-up of own developments in complex digital production management linked to ARTEMIS Zrt.
• The drop in OTHER EXPENSES is due to the phasing out of the capacity tax from 2025, while the specific balancing surcharge for energy producers scheduled under KÁT has increased, mainly driven by external market impacts.

• By the end of 2024, ALTEO's renewable energy production portfolio had significantly expanded: the total installed capacity of the segment reached 115 MW, with the addition of 20 MW of photovoltaic capacity through the commissioning of EDELYN SOLAR Kft. in August 2024, and the 24 MW wind turbine added with the acquisition of Mov-R Kft. in October 2024.
• The revenue increased by HUF 597 million (34%) due to a larger portfolio and higher electricity prices, the positive impact of which was partly offset by unfavorable weather conditions compared to last year, and the lowest level of wind turbine production in the past five years. We expect the weather effects to level off in the medium to long term, but at the same time to increase deviations between years and quarters as the renewable portfolio grows.
• MATERIAL AND PERSONNEL EXPENSES increased primarily in connection with the operation and maintenance of new capacities, while the segment's EBITDA INCREASED BY HUF 388 million (32%).

The Energy Services segment realized an EBITDA of HUF 104 million. The segment's result does not include the added value of inward work, which is reflected in lower investment costs compared to outward work.

• The Business and Project Development division provided project management services to external partners with lower volumes than in the previous year. In 2025, the MOL PV project ensures the return of the segment.
• The profit realized by the segment from operation and maintenance services for third parties (MOL, Borsodchem, Budapest Power Plant, Főtáv, Siemens, Uniper) was nearly identical to the comparative period.
• The strategic cooperation with MOL, which started in 2023 continues in 2025, including exploring opportunities for cooperation in implementation, maintenance and operation. In the first quarter, the Maintenance segment operated with lower revenues than in the previous period, but the preparatory negotiations and works for the sale/installation of gas engines, which will provide higher profitability in the second half of the year, have commenced.
• The E-MOBILITY business, as expected, has no significant profit-generation capacity at present.

• Revenue increased by HUF 195 million (17%) compared to the previous year's base period, in which the increase in revenue from non-concession activities played an important role, and significant growth was also seen in revenue from the organic waste segment.
• The HUF 272 million increase in material expenses comprises activities aimed at further growth. One of the main factors influencing the change is the increase in contract work costs (155 million), which was aimed at keeping inventories as low as possible, and the costs of biogas feedstock, which contributed significantly to realizing higher revenues, are also shown on this line. In the case of personnel expenses, there is a wage increase at the beginning of the year, with the aim of recruiting as many own workforce members as possible to ensure more costeffective operation.
• Overall, the segment's EBITDA was HUF +314 million compared to HUF 444 million in the base period. In order to reduce this shortfall, we aim to replace the much more expensive contract labor workforce with our own staff in the coming period.
• The identification of areas with real potential for savings is underway by the business side, and several efficiency improvement and monitoring activities have been launched.

RETAIL ENERGY TRADE

• The segment's higher REVENUE AND MATERIAL EXPENSES compared to the same period of last year were driven by a significant increase in the electricity portfolio (+44 GWh, +37%), driven by the business line's outstanding sales activity. Compared to 2024, risks and uncertainty have been even further reduced, which has also generated a reduction in the available specific margins.
• The slight change in EBITDA for the segment is due to lower margins resulting from increasing competition, the impact of which is mitigated by significant PORTFOLIO GROWTH.
• The ELECTRICITY TRADE MARGIN shows a slight decrease compared to Q1 of the previous year. The negative impact was due to the declining price environment and increasing competition, partly offset by the portfolio growth achieved.
• The GAS TRADE BUSINESS reported HIGHER MARGINS on account of a 39% increase (+30 GWh) in volume compared to Q1 of the previous year. The increase in volume is also partly due to colder winter weather than last year, which led to an increase in consumption by heating customers.

OTHER ACTIVITIES NOT ASSIGNED TO SEGMENTS

• The segment shows costs primarily related to strategic growth and stock exchange presence that are not linked to specific segments, but rather the future growth of the Group as a whole, and as such are not part of distributed administrative expenses.
• The increase in costs relative to the comparative period was mainly due to long-term employee incentive schemes. ALTEO continues to attach priority importance to retaining and motivating its outstanding team of experts to implement its long-term strategy. Accordingly, in previous years ALTEO introduced an employee share ownership program (ESOP), which keeps its experts, executives and management closely involved and invested in long-term value creation through the implementation of the strategy. ESOP programs include a share price contingent payment. Compared to ALTEO's price of around HUF 4,000 at the beginning of the year, there was a significant increase seen by the end of the quarter.

In 2025, the allocation of administrative costs has been reviewed to track significant changes in central organizations. The time/resource allocation for the organizations to be allocated and the role of existing and newly created areas in supporting operational or strategic operations was reviewed in detail. The figures for the previous year are shown unchanged. The 2025 result is now shown broken down according to the new allocation, and the methodology is updated each year to reflect possible structural changes as growth occurs.
