RECENT INCREASE OF POWER PRICES IS DRIVEN BY GROWTH OF CARBON ALLOWANCES

Development of prices of electricity price and carbon allowances

Czech baseload in EUR/MWh, EUR/t for carbon, Y+1

Continued increase in the price of carbon allowances has been the main reason for the recent increase in electricity prices

1 EUR/t change in carbon allowance implies 0.5-0.6 EUR changes in electricity price

CEZ GROUP BENEFITS FROM INCREASING CARBON PRICES

14

CEZ Group's emission intensity (tCO² /MWh of generated electricity)

WE HAVE A ROBUST GENERATION PORTFOLIO WITH LOW AND LARGELY FIXED COSTS

We have diversified generation portfolio

Generation capacity and volumes (strategic assets)

Our fuel costs are low, not dependent on commodity prices

Current marginal costs by technology (fuel and carbon, EUR/MWh)

* Nuclear fuel costs + CZK 55/MWh payment for fuel storage

** Cash cost of extracting own lignite, 42% efficiency, 11.5 GJ/t calorific value, carbon at 53 EUR/t

*** Gas 25 EUR/MWh, 57% efficiency, 0.35 t/MWh CO2 (gas prices depend on market)

NUCLEAR PLANTS ARE IMPORTANT PROFIT GENERATORS WITH STABLE PRODUCTION VOLUMES

Our nuclear fleet has low and fixed costs and benefits directly from increasing power prices

• y Operating licenses secured enabling 60 years operating life, i.e., remaining 30+ years of operations until decommissioning
• y We have stabilized production volumes at above 30 TWh per year
• y Capacity increased by 568 MW to 4,290 MW by technical improvements (fuel with higher enrichment, modernization of turbines and generators)

NEW NUCLEAR PROJECT IS IN THE FIRST PREPARATORY STAGE THAT IS COVERED BY THE SIGNED FIRST IMPLEMENTATION CONTRACT…

** It does not include the costs incurred until 2020 for the permitting and contracting and the purchase of land; assuming the current supplier model

… GOVERNMENT SHALL PROVIDE FINANCING FOR PERMITTING AND CONSTRUCTION PHASES AND SECURE THE OPERATION BY POWER PURCHASE AGREEMENT

Currently contemplated financing structure*

• y CEZ Group will fund Stage 1 entirely through its equity investment. (ca EUR 0.2 billion**)
• y Stage 2 onwards will be financed by the repayable financial assistance from state (RFA)
  • During 2024-2029 in the Stage 2 in the amount ca EUR 0.7 billion
  • During 2029-2038 in the Stage 3 and 4 in the amount ca EUR 5.1 billion

Repayable Financial Assistance from state (RFA)

• y 0% during the period of construction
• y During period of operation: costs of State debt financing plus 1% but not less than 2% p.a.
• y Duration 30 years from the start of operation of NPP

As a result of a higher share of state financing, the offtake price is expected to be between 50-55 EUR/MWh, i.e., in the lower interval of the originally assumed range of 50-60 EUR/MWh (subject to EPC tender results)

Additional cost overrun financing mechanism

y CEZ Group will not bear any risk of additional costs in case of "legitimate grounds", the Czech state bears the additional costs

Test on the overcompensation will be implemented in the PPA contract

y The mechanism according to the low-carbon law will ensure adequacy of the purchase price and return (regular review after 5 years)

This model will be further discussed in the prenotification with the European Commission and finalized

We are No. 1 player in Czechia

We are within Top 3 players in Germany

We are helping our customers to decarbonize by:

• y Installation of efficient cogeneration units on their sites
• y Providing energy advisory and management
• y Energy storage installations
• y Rooftop photovoltaic plants
• y Lighting, cooling, heating installations

23 * ESCO revenues would be CZK 25.9 billion without Covid-19 related slowdown of CZK 3.9 billion.

** Slowdown due to Covid-19 in International markets: CZK 2.6 billion; Czechia and Slovakia: CZK 1.3 billion

2021 FINANCIAL GUIDANCE MAINTAINED: EBITDA OF CZK 57–60 BILLION, ADJUSTED NET INCOME AT CZK 17–20 BILLION

Adjusted net income

Main Year-On-Year Effects (2021 vs 2020)

y Higher realization prices of electricity y Higher generation at nuclear plants y Stabilization of the Retail segment after the impacts of Covid-19 on corporate customers y Sale of Romanian and Bulgarian assets y Higher expenses on emission allowances for generation y Lower revenue from ancillary services y Effect of a new regulatory period on CEZ Distribuce in Czechia

* The contribution of assets held for sale to CEZ Group's EBITDA will depend on the settlement date of the sale of Bulgarian assets

** We estimate the contribution of assets held for sale to the 2021 consolidated net income at nearly zero, especially in view of concluded contracts for the sale of foreign assets, under which any profit from 2021 belongs to the buyers

Modern distribution and a care for customers' energy needs

Development of new energy in Czechia

Development of energy services in Europe

Vision 2030 Strategic directions CLEAN ENERGY OF TOMORROW

I Decarbonize generation portfolio and reach carbon neutrality

Efficiently managing nuclear power plants and preparing conditions for the construction of a new nuclear power plant as part of enhancement of energy security in Czechia

Efficient management of coal-fired power plants located near the coal basins and decarbonization of Czech generating portfolio (including transformation of the heating industry)

Developing renewable energy sources (RES) while fulfilling the Czech energy and climate plan

Provide best energy solutions and highest quality customer experience and on market II

Modernizing and digitizing distribution and retail in Czechia, developing comprehensive services with respect to customers' needs.

Developing energy services sources (ESCO) in Czechia while fulfilling the Czech energy and climate plan.

Developing energy services (ESCO) abroad to achieve a significant market position in Germany, Northern Italy, and Poland ²⁹

UNDER THE CURRENT STRATEGY WE ARE ACCELERATING DEVELOPMENT. WE WANT TO ACHIEVE 40% INCREASE IN EBITDA BY 2030

Vision 2030 CLEAN ENERGY OF TOMORROW

• Decarbonize generation portfolio and reach carbon neutrality ^I
• Provide best energy solutions and highest quality customer experience and on market II

* Assuming forward power prices from March-2021, which were escalated and sensitivity was applied; carbon allowance price assumption for 2020: 25 EUR/t; 2025: 41 EUR/t; 2030: 46 EUR/t,

** Including financial investments

WE CAN EXECUTE OUR 2030 GROWTH STRATEGY WHILE KEEPING LEVERAGE WITHIN OUR TARGET

We will continue to generate positive free cash flow even with the increased Capex and our leverage would stay below 3.0x of EBITDA

Note: Organic growth = new renewables and gas capacities, expansion of distribution network, Acquisitions = ESCO companies abroad

EBITDA SENSITIVITY TO CHANGES IN WHOLESALE ELECTRICITY PRICES AND CARBON ALLOWANCES AS A DIFFERENCE BETWEEN CURRENT FORWARD PRICES AND BUSINESS PLAN

* Assuming market prices from March-2021 inflationary adjusted

** Escalated forward prices assumed and sensitivity applied: sensitivity assumed as if in 2025 and 2030 wholesale electricity prices are at the level of current forward Y+3 (19th July 2021: CZ baseload 2024 - 61 EUR/MWh, EUA 2024 - 54 EUR/t) and escalated by the inflation

We will increase storage capacities to above 300 MWe

* 2020 figures exclude contribution from 600 MW of Romanian wind, which was disposed on Mar-31, 2021

** Capex conservatively assumes no subsidies on Capex from Modernisation fund due to their uncertain amount

*** Realized prices for renewables will be adjusted by the shape discount (0.8-0.9) on top of wholesale power price

MODERNISATION FUND TO SUPPORT DEVELOPMENT OF PHOTOVOLTAICS IN CZECHIA

Indicative allocation from Modernisation fund to different grant categories

Support of renewables from Modernisation Fund

• y In 2021–30 CZK ~66 billion* is available for grants to support renewables projects, out of which 60% will be dedicated to projects of existing electricity producers
• y Actual amount of subsidy to be determined during auctions, grants will fund the Capex at max 60% or CZK 6.2-7.3 m/MW**
• y Production of renewables will be sold at market prices

CEZ Group submitted 296 projects for photovoltaics to the prequalification round

Receipt of applications for first round of grants starts in July 2021

** 60% for project submitted by large companies outside of Prague, maximum per MW grant depends on size and technology (rooftop or ground-mounted)
