A. 1Q2023 Highlights

Resolution 826/2022

On December 12th, 2022, through Resolution 826/2022 the Secretariat of Energy authorizes generators a tariff increases of 25% in February 2023 and 28% in August 2023 to Spot Energy.

Resolution 59/2023

On February 7^th, 2023, through Resolution 59/2023 the Secretariat of Energy authorizes generators that have combined cycle units to adhere to the Agreement on Availability of Power and Improvement of Efficiency with the aim of encouraging the necessary investments of Major and Minor Maintenance of the machines. Through this agreement, the adhering generators undertake to achieve, at least, 85% availability of average monthly power in exchange for a new power and generation price.

In the case of Power, an amount of 2,000 USD/Mw-month is established plus the sum in pesos corresponding to 85% and 65% of the power value established in Resolution 826/22 for the periods of spring/autumn and summer/winter respectively. Additionally, the price for generated energy is set at 3.5 USD/MWh in the case of using gas and at 6.1 USD/MWh for alternative fuel (diesel).

The adherence to the Agreement by the Company, together with the improvements set by Resolution 826/22 represents a significant increase in the income of the thermal units, the effects of which will be fully verified in the 2023 period.

Proener S.A.U acquires Enel Generación Costanera S.A.

On February 17^th, 2023, Proener acquired from Enel Argentina S.A. 75.68% of the capital and voting stock of Enel Generación Costanera S.A. ("Central Costanera"). The transaction price amounts US$ 48.0 million.

By taking possession of Central Costanera, Central Puerto reinforces its growth in Argentina consolidating as market leader in the generation sector.

The value of Central Costanera represents a unique opportunity as a strategic asset. The growth potential of this acquisition is based on the operational and corporate synergies, experienced management, and knowledge in technical and operational field. We believe that it is necessary to increase the power availability of the Costanera machines to strengthen and cover the demand at the national level.

All of this means that the acquisition cost does not accurately reflect the enormous growth potential of Central Costanera.

Central Costanera is in the City of Buenos Aires, reaching almost 6% participation in the total installed capacity of SADI and generates energy demanded by 3.5 million homes throughout the country. Currently, the Costanera plant is made up of six turbo-steam units, with an installed capacity of 1,131 MW of power, and two Combined Cycle units of 1,133 MW.

Proener S.A.U acquires EVASA group.

On May 3, 2023, Proener S.A.U., acquired 100% of the capital stock and votes of Empresas Verdes Argentina S.A., Las Misiones S.A. and Estancia Celina S.A, consisting of 88,063 hectares geographically located in the center of the province of Corrientes, of which approximately 26,000 hectares are planted with pine out of a total of approximately 36,000 plantable hectares.

The Company is focus on increase its environmental performance and contributing to global decarbonization objectives.

B. Market Overview

The table below sets forth key market data for 1Q2023, compared to 4Q2022 and 1Q2022.

Source: CAMMESA; company data.
¹ EoP refers to "End of Period".

Installed Capacity: In 1Q2023, the installed capacity reached 43,278 MW, compared to 42,871 MW in 1Q2022, resulting in 1%increase. The installed capacity from thermal´s sources increased 1% from 25,274 MW in 1Q2022 to 25,533 MW in 1Q2023, while renewable´s capacity increased 3% to 5,156 MW in 1Q2023 compared to 5,008 MW in 1Q2022. There were no new hydro projects or nuclear in this period.

Between 1Q2023 and 1Q2022, the variation in installed capacity was 407 MW, increasing the capacity of the system. Regarding thermal sources, the increase of 260 MW is related with combine cycle Ensenada Barragan Site. Regarding renewable sources, 147 MW were added to the system, in which the main sources were solar (99 MW) and wind (36 MW).

As of 1Q2023, the installed capacity is divided in 59% thermal, 25% hydro, 4% nuclear and 12% renewable (maintaining the same percentage as in 1Q2022).

Generation: In 1Q2023, energy generation increased 8% to 38,627 GWh, compared to 35,719 GWh in 1Q2022, mainly due to: (i) an 1%increase in thermal generation, (ii) a 74%increase in hydro generation, which was partially offset by: (i) a 28% decrease in nuclear generation (ii) a 3% decrease in renewable generation.

The increase in thermal generation was mainly due to higher dispatch, the average system availability was 73% in 1Q2023, compared to 76% of 1Q2022. The increase in hydro generation is mainly related with the increase in the inflow of the Paraná River. In contrast, in the case of generation from nuclear sources, the decrease is related with a severe technical failure in Atucha II. Regarding renewable energies, the decrease in generation was related to lesser wind resource.

During 1Q2023, the main sources of energy generation continued to be thermal and hydro, with a share of 61% and 22%, respectively. Renewables reached 12%, -1 p.p. (percentage point) less than 1Q2022 while Nuclear decreased -2 p.p. (percentage points) from 7% in 1Q2022 to 5% in 1Q2023. Thermal generation decreased -5 p.p. (percentage points) compared to the same quarter in 2022, as for hydro generation it increased 8 p.p. (percentage points) compared to 2022.

Demand: In 1Q2023, energy demand increased 14% to 39,490 GWh, compared to 34,513 GWh in 1Q2022, in which residential demand grew 25%, commercial 7%, and large industrial/commercial demand a 4%.

The increase in energy demand for both the residential and commercial segments is due to the rise in temperatures and the arrival of summer, there were historically higher temperatures specially at the end of the quarter.

As of 1Q2023 and in terms of demand structure, 49% is represented by residential users, 27% by commercial activity and the remaining 24% is related to great demand industrial/commercial.

1Q2023 Results Analysis

Revenues decreased to Ps. 27.9 billion in the 1Q2023, as compared to Ps. 35.1 billion in the 1Q2022. This 20% decrease represents Ps. 7.1 billon was mainly due to:

1. a 36% decrease in Sales under contracts, which amounted to Ps. 11.7 billion during the 1Q2023, as compared to Ps. 18.4 billion in the 1Q2022, it was impacted by the ending of Brigadier Lopez TG PPA contract in August 2022 and negatively impacted by a higher inflation´s adjustment over the peso´s depreciation in the period. Is worth to mention that the impact related to the ending of Brigadier Lopez TG PPA contract will be recovered with the new PPA contract for the Brigadier Lopez steam turbine when we finish the closing of the combined cycle by the end of 2024.
2. a 7% decrease in Spot/Energía Base Sales (Revenues from Resolution 826/22 SE) which totaled Ps. 13.3 billion in the 1Q2023 as compared to 14.3 billion in the 1Q2022, negatively impacted by a higher inflation´s adjustment over the tariffs increase in the period and due to lower generation mainly for technical failures of Puerto site steam turbines of Ps 2.8 billon, partially offset by Central Costanera revenues of Ps. 1.8 billon.
3. a 23%decrease in the Steam Sales, which totaled Ps. 1.3 billion in the 1Q2023, compared to Ps. 1.7 billion in the 1Q2022.
4. Forestry segment that totaled Ps. 1.0 billion in revenues during 1Q2023.

Operating income before other operating results, was. 8.6 billion, compared to Ps. 17.5 billion in the 1Q2022. This 51% decrease was due to:

1. the above-mentioned drop in revenues.
2. 16% increase in administrative and selling expenses that totaled Ps. 2.4 billion in the 1Q2023, as compared to Ps. 2.0 billion in the 1Q2022, for CPSA the deviation is mainly driven by Ps. 0. 17 billion increases in third party services. Ps. 0. 11 billion from Central Costanera and Ps. 0.05 billion are coming from Forestry segment.
3. 9% increase in costs of sales that totaled Ps 17.0 billion in Q1-23, compared to Ps. 15.5 billion in the 1Q2022. The deviation is mainly explained by including Central Costanera for Ps. 1.3 billon and Forestry Segment Ps. 0.6 billon, partially offset by a reduction in CPSA of Ps. 0.6 billon primarily driven by lower third party services and insurance costs in the 1Q2023.

Adjusted EBITDA was Ps. 29.8 billion in the 1Q2023, compared to Ps. 32.2 billion in the 1Q2022. This decrease was mainly due to:

1. the above-mentioned variations,
2. 3% increase in depreciations and amortizations that totaled Ps. 6.0 billion during the 1Q2023, as compared to Ps. 5.8 billion during the 1Q2022.
   partially offset by:
3. a Ps. 6.4 billion increase mainly explained by i) foreign exchange difference on operating assets, mainly related to FONI trade receivables, that generated a positive variation of Ps. 3.4 billion during the 1Q2023, Ps. 9.4 billon in Q1-23 compared to Ps. 5.9 billion during the 1Q2022 due to a higher depreciation of the Argentine peso during the quarter, ii) an increase in Ps 4.0 billon due to a fair value recognition in biological assets from Forestry segment, iii) a Ps. 1.0 billon decrease in other income results due to an insurance recovery in Q1-22.

As a result, Adjusted EBITDA excluding FX difference, interests related to FONI trade receivables and biological assets fair value recognition was Ps. 16.5 billion in the 1Q2023, compared to Ps. 26.3 billion in 1Q2022. Q1-23 adjusted EBITDA include Ps. 0.8 billon from Central Costanera (since March-23) and Ps. 0.4 billon from Forestry segment.

Consolidated Net Income was Ps. 0.1 billion and Net Income for shareholder was Ps. 0.1 billion or Ps. 0.10 per share or Ps. 1.00 per ADR, in the 1Q2023, compared to a Consolidated Net Income of Ps. 9.8 billion and Net Income for shareholder of Ps. 9.8 billion, respectively, or Ps. 6.50 per share or Ps. 65.02 per ADR, in the 1Q2022. In addition to the above-mentioned factors, net income was negatively impacted by:

1. an increase of Ps. 7.3 billon in net monetary position loss which amounted 13.7 billion during the 1Q2023 due to a higher inflation compared to a Ps. 6.4 billion loss in the 1Q2022.

Adjusted EBITDA

In this release, Adjusted EBITDA, a non-IFRS financial measure, is defined as net income for the year, plus finance expenses, minus finance income, minus share of the profit/ of associates, minus depreciation, and amortization, plus income tax expense, plus depreciation and amortization, minus net results of discontinued operations.

Adjusted EBITDA is believed to provide useful supplemental information to investors about the Company and its results. Adjusted EBITDA is among the measures used by the Company's management team to evaluate the financial and operating performance and make day-to-day financial and operating decisions. In addition, Adjusted EBITDA is frequently used by securities analysts, investors, and other parties to evaluate companies in the industry. Adjusted EBITDA is believed to be helpful to investors because it provides additional information about trends in the core operating performance prior to considering the impact of capital structure, depreciation, amortization, and taxation on the results.

Adjusted EBITDA should not be considered in isolation or as a substitute for other measures of financial performance reported in accordance with IFRS. Adjusted EBITDA has limitations as an analytical tool, including:

• Adjusted EBITDA does not reflect changes in, including cash requirements for, working capital needs or contractual commitments;
• Adjusted EBITDA does not reflect the finance expenses, or the cash requirements to service interest or principal payments on indebtedness, or interest income or other finance income;
• Adjusted EBITDA does not reflect income tax expense or the cash requirements to pay income taxes;
• although depreciation and amortization are non-cash charges, the assets being depreciated or amortized often will need to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for these replacements;
• although share of the profit of associates is a non-cash charge, Adjusted EBITDA does not consider the potential collection of dividends; and
• other companies may calculate Adjusted EBITDA differently, limiting its usefulness as a comparative measure.

The Company compensates for the inherent limitations associated with using Adjusted EBITDA through disclosure of these limitations, presentation of the Company's consolidated financial statements in accordance with IFRS and reconciliation of Adjusted EBITDA to the most directly comparable IFRS measure, net income. For a reconciliation of the net income to Adjusted EBITDA, see the tables included in this release.
