B. Argentine Market Overview

The table below sets forth key Argentine energy market data for 4Q23 compared to 3Q23 and 4Q22 and FY 2023 compared to FY 2022.

Source: CAMMESA; company data.

(1) As of December 31^st , 2023.

Installed Power Generation Capacity: During 2023 , the country's installed generation capacity increased by 2% or 847 MW reaching 43,773 MW, compared to 42,926 MW in 2022. The increase in system's capacity was mainly due to the incorporation of 685 MW (+14%) from renewable sources of which 396 MW corresponds to new wind farms, 280 MW to solar photovoltaic projects, 6 MW to biogas and 3 MW of biomass. In turn, thermal capacity sources recorded a net increase of 162 MW (+1%) as a combination of an addition of 735 MW on new combined cycles and a decrease of 537 MW and 36 MW in gas turbines and diesel engines respectively.

Power generation & demand: In 4Q23 , energy generation dropped 4% to 33,258 GWh, compared to 34,572 GWh in 4Q22, in line with the 4% decrease in energy demand, which was essentially driven by a 5% decline in residential consumption on the back of milder temperatures during the period.

The lower demand of the period was mainly covered with an increase in nuclear (+7% y/y), hydro (+5% y/y) and renewable (+2% y/y) generation, resulting in a lower thermal requirement (-14% y/y).

In the first case, the increase in generation was a direct result of the re-commissioning of the Atucha II power plant as previously explained and the higher generation from Embalse, which was in maintenance shutdown during the same period 2022. With regards to the increase hydro generation, this was mainly due to the higher river flow rates, especially the Uruguay River, which recorded a 484% increase in flow after the severe drought recorded during 2022, while the rivers of the Comahue basin also recorded higher flows, with the Nequén and Limay rivers standing out with increases of 49% and 37%, respectively.

C. Central Puerto S.A.: Main operating metrics

The table below sets forth key operating metrics of the Central Puerto group for 4Q23, compared to 3Q23 and 4Q23, and FY 2023, compared to FY 2022:

Source: CAMMESA; company data.

(1) On February 22, 2024, it was published in the Official Gazette of the Republic of Argentina, the request submitted by Central Costanera for the decommissioning of steam generation units COSTTV04 and COSTTV06, for a total installed capacity of 120 MW and 350 MW, respectively.

Thermal availability ⁽¹⁾⁽²⁾
(%)

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

(2) Central Costanera figures does not consider the power capacity values of the steam generation units COSTTV04 and COSTTV06

During 4Q23, Central Puerto's operated power generation increased by 10% to 5,168 GWh, compared to 4,687 GWh in 2022.

It should be noted that this increase includes the consolidation of the energy generated by Central Costanera (+856 GWh) and Guañizuil II A solar plant (+73 GWh).

In 4Q23, the increase in hydro energy generation from Piedra del Aguila was once again noteworthy, reaching 1,678 GWh and standing 21% above 4Q22 levels, as a direct result of the increase in the flows of Limay and Collon Curá rivers (+37% and +13%, respectively) compared to 4Q22, when river flows were still affected by the drought that impacted the country in 2022.

With regards to renewables, energy generation increased by 12% in 4Q23 vís-a-vís 4Q22, being fully explained by the incorporation of the 73 GWh generated by Guañizuil II A solar plant and being partially offset by a 5% contraction in wind generation as a result of lower wind resource during the period.

Regarding thermal generation, it increased by 5% in 4Q23 compared to 4Q22, as a result of the acquisition of Central Costanera. Excluding this power plant from the analysis, thermal power generation would have recorded a 25% decrease vís-a-vís 4Q22, as a result of a higher availability of hydro generation, as previously stated, and the lower energy demand of the period, resulting in a lower thermal dispatch, particularly in the Puerto complex, Lujan de Cuyo and Brigadier Lopez sites.

Finally, steam production increased 25% during 4Q23, explained by a 29% increase in San Lorenzo cogeneration plant and a 23% increase in Lujan de Cuyo. In the first case, the increase is mostly explained by an increase in must-run operations, while in the second case the result is basically explained by higher availability of gas turbines (maintenance finished by mid-2023, which highly improved 4Q23 operation performance).

D. FY & 4Q23 Analysis of Consolidated Results

Important notice: "The results presented for the annual period 2023 and 4Q23 are negatively affected, at a non-cash level, as a consequence of the sharp devaluation of the local currency occurred in mid-December, in Central Puerto's accounting methodology. Given that the functional currency of the company is the Argentine peso, our Financial Statements are subject to inflation adjustment, while Company's figures are converted into US dollars using the end of period official exchange rate. Thus, given the significant disparity between inflation and devaluation for the period, it might affect comparability".

Main financial magnitudes of continuing operations (1)

(1) The FX rate used to convert Argentine Pesos to U.S. dollars is the reference exchange rate (Communication "A" 3500) reported by the Central Bank for U.S. dollars as of Dec-31st of AR$ 808.48 to US$1.00.

(2) See "Disclaimer-EBITDA & Adjusted EBITDA" on page 21 for further information.

During 4Q23, revenues totaled US$98.0 million decreasing 19% compared to US$120.9 million in the 4Q22.

This was mainly due to a combination of:

i. A US$4.3 million sales from the Forestry companies acquired in December 2022 and May 2023.

ii. A 21% or US$11.6 million decrease in sales under contracts, which totaled US$42.7 million in 4Q23 compared to US$54.3 million in 4Q22, mainly explained by the aforementioned effect between inflation and currency devaluation and to a lower generation from our wind farms on the back of a lesser wind resource, being partially offset by the recent acquisition of the solar farm Guañizul II A which contributed with sales of US$2.7 million in the quarter.

iii. A 19% or US$11.3 million decrease in Spot/Legacy energy sales which amounted to US$40.4 million in 4Q23 compared to US$59.4 million in the 4Q22, driven by a combination of the consolidation of Central Costanera's figures which contributed with sales of US$13.4 million, and a higher energy dispatch from Piedra del Aguila hydro power plant, being fully offset by the aforementioned effect between inflation and currency devaluation, a lower remuneration measured in US dollars, a lower generation from thermal units on the back of the lower demand of the period and the higher availability of hydro resource,

iv. A 15% or US$0.7 million decrease in steam sales, which totaled US$3.8 million in the 4Q23 compared to US$4.5 million in the 4Q22, despite a 25% increase in volumes being fully explained by the aforementioned non-cash effect between inflation and currency devaluation.

Operating cost, excluding depreciation and amortization, in 4Q23 amounted to US$40.4 million, decreasing by 13% or US$5.8 million when compared to US$46.3 million in 4Q22.

The decrease is basically explained by the aforementioned effect between inflation and currency devaluation and the reclassification of consumption of materials and spare parts allocated to the maintenance works carried on the cogeneration units of Lujan de Cuyo plant.

Other than the aforementioned effects, production costs increased by 11% or US$3.7 million primarily due to: (i) higher purchases of energy and power, (ii) other long-term employee benefits and (iii) consumption of material and spare parts.

In addition, SG&A, excluding depreciations and amortizations, increased by 9% or US$1.1 million in the year over year comparison due to: (i) an increase in compensation to employees and (ii) tax on bank account transactions.

Other operating results net in 4Q23 were positive in US$128.3 million, increasing 133% or US$73.2 million compared to 4Q22 . This is mainly explained by the higher exchange rate differences and interest accrued from the FONI program for a total net increase of US$71.9 million in 4Q23.

In addition, during the quarter a recovery of impairment of property, plant and equipment and intangible assets was recorded for US$54.4 million as opposed to the negative charge of US$79.2 million recorded in 4Q22.

Consequently, Consolidated Adjusted EBITDA ^([1]) amounted to US$45.2 million in 4Q23 , compared to US$68.1 million in 4Q22.

Consolidated Net financial results in 4Q23 were negative in US$105.8 million compared to a loss of US$35.0 million in 4Q22 mainly driven by higher negative foreign exchange differences on financial liabilities partially offset by better results from holding financial assets at fair value.

Loss on net monetary position in 4Q23 measured in US dollars amounted to US$41.5 million being 11% lower to the US$46.8 million loss in 4Q22, driven by the impact of the higher inflation of the period on a lower balance of monetary assets in Argentine pesos.

Profit on associate companies was positive on US$5.5 million compared to a US$1.4 million loss in 4Q22.

In addition, during 4Q23 the Company recorded a gain as a result of the valuation at fair value of the companies acquired during the period for US$89.9 million.

Income tax in 4Q23 resulted in a positive US$6.0 million compared to, also positive, US$7.9 million in 4Q22.

Finally, Net Income in 4Q23 amounted to US$155.8 million, compared to US$13.3 million of 4Q22.

FONI program collections associated to the receivables from the Vuelta de Obligado plant totaled US$11.2 million in 4Q23. This amount is composed by US$10.8 million corresponding to Central Puerto and US$0.4 million to Central Costanera.
