• EBITDA is expected at CZK 115-120 bn.
• Net income adjusted for extraordinary effects is estimated at CZK 25-30 bn.
  • * Adjusted net income = Net income adjusted for extraordinary effects that are generally unrelated to ordinary financial performance in a given period (in particular fixed asset impairments and goodwill impairment).

Main Causes of Year-over-Year Change in EBITDA

GENERATION Segment – Generating facilities (CZK +3.8 bn)

• Levy on revenues above price caps from generation in Czechia in Q1 2023 (CZK +10.3 bn)
• Lower margin from generation in Czechia due to changes in the purchase prices of emission allowances and gas, realized prices of electricity and exchange rate hedging (CZK -5.2 bn)
• Effect of different schedules of planned outages of nuclear facilities (CZK -1.5 bn)

MINING Segment (CZK -1.0 bn)

▪ Lower external revenues due to reduced coal supplies (CZK -0.9 bn)

SALES Segment (CZK +4.2 bn)

• Negative gross margin CZK +3.0 bn from electricity and gas sales in Q1 2023 due to temporary seasonal factors**, fluctuations in consumption, and commodity prices
• The gross margin from electricity and gas sales reached a positive value of CZK +1.2 bn in Q1 2024
  • * Mainly the elimination of the effect of hedging the currency risks of ČEZ ESCO (SALES segment) through ČEZ, a. s. (GENERATION segment), where the effect is reported under foreign exchange gains and losses (outside EBITDA).
• www.cez.cz 4 ** Prices for end-use customers are generally set the same for winter and summer, while the purchase prices of electricity and gas are generally significantly higher in winter than at other times of the year. In addition, there are temporary effects due to electricity purchases to cover losses in the grid.

We confirm the initial financial outlook for 2024: EBITDA CZK 115-120 bn, Adjusted net income CZK 25-30 bn

EBITDA (CZK bn)

Adjusted net income (CZK bn)

Main year-over-year effects on EBITDA

• – Lower expected income from commodity trading (CZK -8 to -4 bn) due to the achievement of the 2nd highest income in history (CZK +9.4 bn) in 2023
• – Lower sales for ancillary services and higher purchase prices of emission allowances
• – Higher fixed operating expenses
• + Realized prices of electricity incl. effect of exchange rate hedging
• + Levies on revenues above price caps from generation in 2023

Selected assumptions of the current forecast

• Total electricity supply from generation in Czechia of ~42 TWh
• Average realized price of electricity generated in Czechia of EUR 130 to 135 per MWh
• Acceleration of depreciation of coal-fired power plants
• Windfall tax of CZK 25–32 bn

Selected prediction risks and opportunities

• Availability of generating facilities
• Realized prices of generated electricity
• Income from commodity trading and revaluation of derivatives
• Amount of the income tax base

The given predictions of CEZ Group's financial targets do not include the contribution of the potential purchase of a stake in Czech Gas Networks. The transaction is subject to the approval of the European Commission.

New nuclear power plant in Dukovany – receipt of supplemented bids and approval of state aid by EU

Elektrárna Dukovany II received updated bids for the construction of new nuclear power plants

• The French EdF and the Korean KHNP submitted updated bid for the construction of the fifth nuclear unit in Dukovany and for three more units at existing nuclear sites.
• The winner of the tender for the new nuclear unit in Dukovany is expected to be selected in 2024 and the contract is expected to be signed with the selected bidder by March 31, 2025.
• The overall schedule remains unchanged the goal is to start trial operation of the new unit in 2036.

The European Union has approved state aid for the new nuclear unit in Dukovany

• The approved state aid for the construction of the fifth unit in Dukovany constitutes a significant milestone in the development of nuclear energy in Czechia
• Decision of the EC SA.58207 concerns the new nuclear unit in Dukovany with a capacity of 850 to 1,200 MW^e
• The support for Elektrárna Dukovany II contains three measures:
  • Contract on the purchase of power from the new nuclear power plant for 40 years
  • Repayable financial assistance for financing the construction of the new nuclear unit by the Czech state
  • Contractual instrument to protect the investor against changes in the legislative and regulatory environment in Czechia
• The purchase contract guarantees the investor protection against a decrease in future electricity market prices. If the market price of electricity falls below the set purchase price, the state (or an authorized entity) pays the difference to the investor. If, on the other hand, the electricity market price exceeds the set purchase price, the investor pays the difference back to the state.

Status of price risk hedging of the generation margin in Czechia and expected realized prices of generation for 2024

Electricity – share of hedged supplies from generation in Czechia

Electricity – status of generation revenue hedging* in Czechia

• As at March 31, 40.7 TWh sold at an average realized price of EUR ~130 per MWh
• Current open position assumption of ~1.4 TWh
• Average expected realized price for 100% supply of generated electricity** is EUR 130-135 per MWh.
  • * This is the hedging of the generation margin in ČEZ and Energotrans.

Emission allowances – status of generation hedging in Czechia

Emission allowances – status of generation expenses hedging* in Czechia

• As at March 31, 12.5 mil. t contracted at an average purchase price of EUR ~79 per t.
• Current open position assumption of ~ 0 t
• ** This is the result of hedging transactions and the current market valuation of electricity not yet sold and of emission allowances not acquired for expected generation in 2024. Some of the hedging contracts for electricity sales (mainly from gas and some coal-fired facilities) and the purchase of emission allowances, are continuously revalued in the P/L statement due to uncertain final supplies.

Hedging of the market risks of electricity generation in Czechia for 2025–2028

Concluded business contracts as at March 31, 2024

Share of hedged expected generation* in Czechia

2025	2026	2027	2028	Annual expected supplies from electricity
~65%	~35%	~11%	~2%	generation (100%) amount to 37 to 45 TWh

* This is the hedging of the generation margin in ČEZ and Energotrans.

Definitions and Calculations of Indicators Unspecified in IFRS

In accordance with the ESMA guidelines, ČEZ informs in more detail about indicators that are not normally reported in IFRS. Such indicators represent supplementary information in respect of financial data, providing report users with additional information for their assessment of the financial position and performance of CEZ Group. In general, these indicators are also commonly used in other commercial companies, not only in the energy sector.

Below are the definitions of individual indicators, including the specification of components that are not directly available in the financial statements or notes to the consolidated financial statements.

Indicator
EBITDA	Purpose: It is a basic indicator of the operational performance of publicly traded companies, which is monitored by international analysts, creditors, investors and shareholders. The EBITDA value indicates the generated cash flow from operating activities for the past period, i.e., it is the basic source for investment and financial expenses.
	Definition: Included in the notes to the financial statements, the point "Information on segments".
Adjusted Net Income (After-Tax Income, Adjusted)	Purpose: This is a supporting indicator, intended primarily for investors, creditors and shareholders, which allows interpreting the achieved financial results with the exclusion of extraordinary, usually nonrecurring effects that are generally unrelated to ordinary financial performance and value creation in a given period.
	Definition: Net income (after-tax income) +/- additions to and reversals of impairment of property, plant and equipment and intangible assets, including impairment of goodwill +/- additions to and reversals of impairments of developed projects +/- other extraordinary effects that are generally unrelated to ordinary financial performance and value creation in a given period +/- effects of the above on income tax.
Net Debt	Purpose: The indicator shows the real level of a company's financial debt, i.e., the carrying amount of debt net of cash, cash equivalents, and highly liquid financial assets held. The indicator is primarily used to assess the overall appropriateness of the indebtedness, e.g., in comparison with selected income or balance sheet indicators.
	Definition: Long-Term Debt, Net of Current Portion + Current Portion of Long-Term Debt + Short-Term Loans – (Cash and Cash Equivalents + Highly Liquid Financial Assets).
	The components of the indicator, except for Highly Liquid Financial Assets, are reported individually on the balance sheet, with items related to assets held for sale are presented separately on the balance sheet.

Indicator
Net Debt / EBITDA	Purpose: This indicates a company's capability to pay back its debt as well as its ability to take on additional debt to grow its business. CEZ Group uses this indicator primarily to assess the adequacy of its capital structure to the structure and stability of its expected cash flows.
	Definition: Net Debt / EBITDA, where Net Debt is the amount at the end of the reported period. EBITDA is the running total for the past 12 months. March 31 value therefore contains Net Debt as at March 31 and EBITDA for the period from April 1 of the previous year until March 31 of the current year.

Most of the indicators' components are directly calculated in the company's consolidated financial statements. Components not included in the financial statements relate to the Adjusted net income and Net Debt indicators (including derived indicator Net Debt / EBITDA) and are calculated as follows:

Adjusted Net Income Indicator – calculation for period in question:

Adjusted Net Income (After-Tax Income, Adjusted) Unit		Q1 2023	Q1 2024
Net income	CZK billions	10.8	13.6
Impairment of property, plant and equipment and intangible assets (including goodwill write-off) 1)	CZK billions	-0.0	0.0
Impairments of developed projects 2)	CZK billions	–	–
Effects of additions to or reversals of impairments on income tax 3)	CZK billions	0.0	-0.0
Other extraordinary effects	CZK billions	–	–
Adjusted net income	CZK billions	10.8	13.6

1) Corresponds to the total value reported in the row Impairment of Property, Plant and Equipment and Intangible Assets in the Consolidated Statement of Income

2) Included in the row Other operating expenses in the Consolidated Statement of Income

3) Included in the row Income taxes in the Consolidated Statement of Income

Highly Liquid Financial Assets – Component of the Net Debt Indicator (in CZK billions):

	as at Dec 31,	as at Mar 31,
	2023	2024
Current debt financial assets	6.7	6.2
Noncurrent debt financial assets	-	-
Current term deposits	0.1	0.1
Noncurrent term deposits	-	-
Short-term equity securities	0.0	0.0
Highly liquid financial assets, total	6.7	6.3

Totals and subtotals can differ from the sum of partial values due to rounding.
