A. 1Q2021 Highlights

1Q2021 energy generation decreased 11% to 3,479 GWh, as compared to 3,908 GWh during the same period of 2020. Energy generation was positively impacted by the new renewable wind farms Manque, Los Olivos and La Genoveva I and negatively impacted by lower water availability for the Piedra del Águila hydro plant and due to small failures in Puerto´s combined cycle and some of its steam turbines (for more information see section B. Main Operating Metrics).

Results for the quarter ended on March 31, 2021

Thermal units’ availability during the quarter was 89%, compared to 93% in the 1Q2020, and a market average of 81% for the 1Q2021, mainly due to the unavailability of Puerto´s combined cycle and some of its steam turbines.

Terminal 6-San Lorenzo cogeneration plant (391 MW). Construction continues to complete the project closing the cycle and producing steam during the third quarter of 2021. It is important to highlight that on November 21, 2020, the plant obtained partial commissioning of its gas turbine (269.5 MW) and sell energy under the spot market regulation (Res. 31/2020). Once the COD for the full project is achieved the plant will be remunerated under a 15-years PPA with CAMMESA and a Steam Contract with T6.

Refinancing of debt under the terms of Communication “A” 7230 of the Central Bank of the Republic of Argentina (“BCRA”). On February 25, 2021, the BCRA decided to extend the FX regulatory restrictions established by Communication “A” 7106 until December 31, 2021 through the issuance of Communication “A” 7230. The installments, under the Syndicate loan signed with Citibank N.A., JP Morgan Chase Bank N.A. and Morgan Stanley Senior Funding INC for the acquisition of the Brigadier López Thermal Plant, maturing on June, September and December 2021 are under the scope of such regulation. Therefore, and as of the date of this press release, we are maintaining negotiations with these banks to reschedule those installments.

Source: CAMMESA; company data.

1 EoP refers to “End of Period”.

2 Availability weighted average by power capacity. Off-time due to scheduled maintenance agreed with CAMMESA is not considered in the ratio.

In the 1Q2021, energy generation decreased 11% to 3,479 GWh, compared to 3,908 GWh in the 1Q2020. As a reference, domestic energy generation remained stable during the 1Q2021, compared to the 1Q2020, according to data from CAMMESA.

The decrease in the energy generated by Central Puerto was due to:

a)

a 33% decrease in energy generation form the hydro plant Piedra del Águila due to lower water inflow in the Limay and Collón Curá rivers.

b)

a decrease of 7% in the electricity generation from thermal units, primarily from Central Puerto´s combined cycle and some of its steam units due to small failures during the quarter.

This was partially offset by,

c)

a 19% increase in energy generation from renewable units, which increased mainly due to the operation during the full quarter of Manque (57 MW), as the wind farm only had partial COD for 38 MW since December 2019 and increased its capacity to 53.2 MW on January 23, 2020, and to 57 MW on March 3, 2020, Los Olivos (22.8 MW) which started operations on February 2020, and the full commissioning of La Genoveva I since November 2020.

Results for the quarter ended on March 31, 2021

During 1Q2021, machine availability for thermal units reached 89%, compared to 93% in 1Q2020, mainly due to certain small failures in Puerto´s combined cycle during March 2021, and the unavailability for some of Puerto´s steam turbines. As a reference, the market average availability for thermal units for the same period was 81%, according to data from CAMMESA.

Steam production increased 3%, totaling 262,000 tons produced during 1Q2021, compared to 255,000 tons during the 1Q2020, due to good availability and generation of Lujan de Cuyo cogeneration.

1Q 2021 Results Analysis

Revenues decreased to Ps. 10,164 million in the 1Q2021, as compared to Ps. 11,419 million in the 1Q2020. This decrease was mainly due to:

(i)

a 31% decrease in Spot Sales/Energia Base (Revenues from Resolution 1, Resolution 31, Resolution 19 and amendments) which totaled Ps. 4,166 million in the 1Q2021 as compared to 6,050 million in the 1Q2020, mainly due lack of monthly price adjustment of Res.31/2020 instructed by the Energy Secretariat on April 8, 2020 and to a lesser extent to small failures in Puerto´s combined cycle and some of its steam turbines.

2 4Q2020 figures were constructed, as the difference between the 2020 and the 9M2020 financial figures, respectively, informed in the Financial Statements for the quarter and the nine-month period ended on September 30, 2020, stated in the measuring unit current as of March 31, 2021.

Results for the quarter ended on March 31, 2021

partially offset by:

(ii)

an 13% increase in Sales under contracts, which amounted to Ps. 5,444 million during the 1Q2021, as compared to Ps. 4,833 million in the 1Q2020, mainly due to the new windfarms mentioned above.

(iii)

a 9% increase in the Steam Sales, which totaled Ps. 281 million in the 1Q2021, compared to Ps. 258 million in the 1Q2020, as the steam production increased 3% in the quarter.

It is worth mentioning that prices for units under the Energía Base Regulatory framework are established by Res. 31/2020, in force since February 1, 2020, and the Annex VI of such resolution (monthly price adjustment procedure) was suspended by the Secretariat of Energy on April 8, 2020. In this regard the prices for the Energía Base Regulatory framework were fixed in Argentina pesos since February 2020. Currently, the generating companies hold several meetings with the Secretariat of Energy to work on a tariff’s update scheme for 2021.

Gross profit was Ps. 4,973 million in the 1Q2021, compared to Ps. 6,686 million in 1Q2020. This decrease was due to (i) the above-mentioned variation in revenues and (ii) a 10% increase in the costs of sales that totaled Ps. 5,191 million in the 1Q201, compared to Ps. 4,734 million in the 1Q2020. This increase in the cost of sales was primarily driven by:

(i)

A 43% increase in purchases of materials and spare parts which totaled Ps. 1,345 million during the 1Q2021, as compared to Ps. 942 million in the 1Q2020.

(ii)

a 6% increase in costs of production, which totaled Ps. 4,052 million in the 1Q2021, as compared to Ps. 3,806 million in the 1Q2020 mainly due to i) an increase in depreciations of Ps. 349 million and ii) an increase in maintenance expenses of Ps. 173 million.

Gross Profit Margin was 49% during the 1Q2021, as compared to 59% in the 1Q2020.

Operating income before other operating results was Ps. 4,179 million in the 1Q021, compared to Ps. 5,792 million in the 1Q2020. This decrease was due to (i) the above-mentioned decrease in gross profits, partially offset by (ii) a 11% decrease (in real terms) in administrative and selling expenses that totaled Ps. 794 million in the 1Q2021, as compared to Ps. 893 million in the 1Q2020, mainly driven by i) a Ps. 63 million reduction in tax on bank account transactions and ii) a Ps. 48 million reduction in maintenance expenses.

Adjusted EBITDA was Ps. 9,679 million in the 1Q2021, compared to Ps. 10,848 million in the 1Q2020. This decrease was mainly due to:

(i)

A 17% decrease in foreign exchange difference on operating assets, mainly related to FONI trade receivables, that generated a Ps. 2,862 million gain during the 1Q2021, compared to Ps. 3,461 million during the 1Q2020. It is worth mentioning that during 2020, CAMMESA has completed all scheduled payments of principal and interest in accordance with the FONI agreement for Termoeléctrica José de San Martín S.A. (“TJSM”) and Termoeléctrica General Manuel Belgrano S.A. (“TMB”) during 2020. This was partially offset by a higher depreciation of the argentine peso. As reference, during the 1Q2021, the Argentine peso depreciated 9.28%, compared to 7.77% during the 1Q2020.

Results for the quarter ended on March 31, 2021

(ii)

a 44% decrease in interest from clients which totaled Ps. 613 million during the 1Q2021, compared to Ps. 1,094 million of 1Q2020, mainly related to the total collection of the FONI Agreement for TJSM and TMB during 2020.

This was partially offset by:

(iii)

An increase in depreciations and amortizations that totaled Ps. 1,913 during the 1Q2021, as compared to Ps. 1,657 million during the 1Q2020.

Consolidated Net income was Ps. 640 million and Net income for shareholder was Ps. 634 million or Ps. 0.42 per share or Ps. 4,21 per ADR, in the 1Q2021, compared to Ps. 1,364 million and Ps.1,330 million, respectively, or Ps. 0.88 per share or Ps. 8.84 per ADR, in the 1Q2020. In addition to the above-mentioned factors, net income was negatively impacted by (i) higher financial expenses that amounted to Ps. 7,012 million in the 1Q2021, compared to Ps. 6,213 million in the 1Q2020, mainly due to higher foreign exchange difference on loans, most of which are denominated in US dollars and positively impacted by (i) higher financial income which amounted to Ps. 422 million during the 1Q2021, compared to Ps. 186 million in the 1Q2020 and (ii) lower income tax expenses that amounted to Ps. 450 million in the 1Q2021, compared to Ps. 2,325 million in the 1Q2020.

Additionally, the share of profit of associates was Ps. 267 million loss during the 1Q2021 compared to Ps. 77 million gain during the 1Q2020, mainly due to lower results from the operations of Ecogas due to lack of tariff adjustments for the natural gas distribution business.

Finally, the gain on net monetary position totaled Ps. 181 million during the 1Q2021, as compared to Ps. 447 million in the 1Q2020.

FONI collections totaled Ps. 1,109 million in the 1Q2021, -including VAT, associated to the FONI trade receivables for Vuelta de Obligado Plant, compared to Ps. 2,255 million of 1Q2020. The amounts are being collected on time and according to the signed contract.

CAUTIONARY STATEMENTS RELEVANT TO FORWARD-LOOKING INFORMATION

This release contains certain forward-looking information and forward-looking statements as defined in applicable securities laws (collectively referred to in this Earnings Release as “forward-looking statements”) that constitute forward-looking statements. All statements other than statements of historical fact are forward-looking statements. The words ‘‘anticipate’’, ‘‘believe’’, ‘‘could’’, ‘‘expect’’, ‘‘should’’, ‘‘plan’’, ‘‘intend’’, ‘‘will’’, ‘‘estimate’’ and ‘‘potential’’, and similar expressions, as they relate to the Company, are intended to identify forward-looking statements.

Statements regarding possible or assumed future results of operations, business strategies, financing plans, competitive position, industry environment, potential growth opportunities, the effects of future regulation and the effects of competition, expected power generation and capital expenditures plan, are examples of forward-looking statements. Forward-looking statements are necessarily based upon a number of factors and assumptions that, while considered reasonable by management, are inherently subject to significant business, economic and competitive uncertainties, and contingencies, which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

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.
