1. Relevant Events

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.1** **Power generation segment** 

***Wind expansion: acquisition of VAR and development of PEPE IV and PEPE VI***

On December 16, 2022, Pampa acquired 100% of VAR, a company formerly owned by the Provincial Government of La Rioja. VAR operates PEA, a 100-MW wind farm located in Arauco, province of La Rioja. It has been selling its output under a 20-year RenovAr PPA since March 2020. The acquisition price amounts to US$170 million, of which US$128 million were paid at closing, while the balance will be settled in 12 monthly installments during 2023.

Regarding the expansion projects, 4 of the 18 4.5 MW Vestas wind turbines were commissioned in PEPE IV on December 29, 2022, and 4 additional wind turbines were online on February 25, 2023 (a total of 36 MW). Therefore, the full COD is estimated by the second quarter of 2023. Moreover, the construction of PEPE VI was announced on February 2023, a project that comprises 300 MW of wind energy in three stages. The first stage will install 94.5 MW, disbursing approximately US$186 million over a total investment exceeding US$500 million for the entire project. PEPE VI is located next to PEMC and PEPE II, 18 km from the city of Bahía Blanca, province of Buenos Aires. Pampa will mount 21 Vestas wind turbines, projecting its commissioning by the third quarter of 2024. Both wind farms will sell energy in the MAT ER under US$-PPA with private parties.

***Commissioning of the closing to CCGT at CTEB***

As of February 22, 2023, at midnight, CAMMESA commercially commissioned CTEB's EBARTV01 unit for a gross capacity of up to 260 MW, thus completing the CCGT project. Since this milestone, CTEB bills the stipulated remuneration under the 10-year PPA with CAMMESA under SE Res. No. 220/07. Consequently, CTEB's total gross capacity amounts to 827 MW, contributing a cleaner and more efficient plant to the national power grid.

Pampa, a co-controller shareholder with YPF, jointly invested more than US$250 million in the project. With this milestone, the guarantees' resolutory condition as guarantors of CTBSA's CB is fulfilled.

***Updates to the legacy remuneration scheme (energy sold under spot or without PPA)***

In December 2022, SE Res No. 826/22 increased 20% of the remuneration scheme as of June 2022, which is applicable from September 2022. Moreover, the Res. set a cumulative raise of 10% in December, 25% in February and 28% in August 2023. Finally, the Res. replaces the HMRT power remuneration with peak-hour energy generation as of November 2022.

***Differential remuneration for CCGT under legacy energy***

SE Res. No. 59/23 was published on February 7, 2023, seeking to promote the CCGT's operational performance under the legacy energy scheme. Power producers are encouraged to execute a PPA with CAMMESA for up to 5 years, committing to maintain at least 85% net capacity availability.

In consideration, the capacity will be partially priced in US$, combining: **(i)** US$2,000/MW-month payment, linearly decreasing if availability falls below 85%, but setting a US$600/MW-month floor if availability is less than 50%; and **(ii)** 65% of the legacy's capacity with DIGO price in AR$ for summer and winter, and 85% for the rest of the year. Moreover, the energy price generated by firing natural gas is US$3.5/MWh, US$6.1/MWh using FO o GO and US$8.7/MWh using biofuel. Operated and generated energy in peak hours will continue being remunerated in AR$ as legacy energy.

![](pampr4q226k_009.jpg)

Power producers may adhere to the Res. from 90 days after its publication. Pampa is analyzing because two CCGTs would apply under this scheme, CTLL and CTGEBA, with a 1,239 MW total capacity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.2** **Oil and gas segment** 

***Plan Gas.Ar: rounds 4 y 5***

On December 22, 2022, rounds 4 (Neuquina Basin) and 5 (Austral Basin) were awarded through SE Res. No 860/22. In particular, rounds 4.1 and 5.1 extended most of the annual base volume from December 2024 until December 2028 under the following conditions:

&nbsp;&nbsp;&nbsp;&nbsp;· Round 1: 48.0
million m<sup>3</sup>/day at a price of US$3.592/MBTU in Neuquina Basin and 2.4 million m<sup>3</sup>/day at a price of US$3.479/MBTU
in Austral Basin; and

&nbsp;&nbsp;&nbsp;&nbsp;· Round 3: 3 million
m<sup>3</sup>/day priced at US$3.435/MBTU at Neuquina Basin.

Round 4.2 awarded new volumes until December 2028, which can be limited up to 30% with ENARSA as offtake to industrial clients and/or GNC, subject to the SE's approval:

&nbsp;&nbsp;&nbsp;&nbsp;· Annual flat
commitment since July 2023: 11 million m<sup>3</sup>/day at a price of US$3.41/MBTU;

&nbsp;&nbsp;&nbsp;&nbsp;· Annual flat
commitment since January 2024: 3 million m<sup>3</sup>/day at a price of US$2.989/MBTU;

&nbsp;&nbsp;&nbsp;&nbsp;· Peak commitment
(winter) from 2024: 7 million m<sup>3</sup>/day at a price of US$4.249/MTBU; and

&nbsp;&nbsp;&nbsp;&nbsp;· Peak commitment
(winter) from 2025: 7 million m<sup>3</sup>/day at a price of US$3.597/MTBU.

Finally, round 5.2 awarded the maximum incremental volume vs. round 1 for 3.3 million m<sup>3</sup>/day at a price of US$7.319/MBTU for 2023-2028. CAMMESA is the client, with a daily DoP and monthly ToP of 80%.

Through round 4.1 results, Pampa extended until 2028 4.9 million m<sup>3</sup>/day awarded from round 1 at US$3.60/MBTU and 2 million m<sup>3</sup>/day from round 3 for US$3.347/MBTU. In addition, Pampa was granted an annual flat volume in round 4.2 for 4.8 million m<sup>3</sup>/day at US$3.485/MBTU, deliverable from July 2023.

![](pampr4q226k_001.jpg)

**Note**: Production assumes maximum daily volumes are delivered per contract.

***Permits to export gas to Chile***

PEN Executive Order No. 730/22, issued on November 4, 2022, allows exports on a firm basis even in winter, prioritizing producers with the most competitive prices and/or contributing with a higher volume under Plan Gas.Ar, always prioritizing internal supply.

Therefore, SE Res. No. 774/22 was issued on November 16, 2022, establishing the following: **(i)** No producer will export more than 30% of the authorized export quota per basin or more than 50% of the commitment under Plan Gas.Ar; **(ii)** ToP export quotas per basin are assigned for higher offered volume (45%) and price (55%); **(iii)** export volume will reduce Plan Gas.Ar commitment only during off-peak months ; **(iv)** minimum price will be the higher between a percentage of Brent set by the applicable authority and the seasonal-adjusted Plan Gas.Ar price; **(v)** reduction on committed volumes under Plan Gas.Ar with CAMMESA and/or ENARSA (previously, reductions were available only with CAMMESA).

![](pampr4q226k_009.jpg)

In February 2023, the SE approved Pampa's export requests on a ToP basis to Chile for a maximum of 1.31 million m<sup>3</sup>/day between May-June 2023 (winter months).

***Foreign currency scheme access for incremental hydrocarbon production***

Access to MULC will be allowed to pay principal and interests on commercial or financial liabilities held with foreign parties, including liabilities with non-resident related companies, and/or profit and dividends corresponding to full audit annual financial statements, and/or repatriation of direct investment made by non-resident companies.

In the case of natural gas, the MULC quota equals 30% of the incremental injection valued at the rolling 12-month-weighted average export price of Argentina, net of export duties. For oil, the quota is equivalent to 20% of the quarter's incremental production valued at Brent's rolling 12-month-average quote, defined by the applicable authority, net of export duties and adjusted by the crude oil's quality<sup>[4]</sup>. Moreover, the quotas may be assigned to direct suppliers, associated third parties and/or block operators.

Pampa submitted a request to join both schemes and the quota benefits calculations for the third and fourth quarters of 2022. However, as of today, the SE has not responded to our request.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.3** **Other news** 

***Transener and TGS's tariff situation***

On December 2022, Transener and Transba's tariff schemes dated February 2022 were incremented by 155% and 154%, respectively, applicable since January 1, 2023 (ENRE Res. No. 698/22 and 702/22).

On the other hand, TGS's public hearing took place on January 4, 2023, requesting a 135% tariff increase on March 2022's schemes, to be applicable since February 2023. As of today, TGS is awaiting a response from ENARGAS.

***TGS: Vaca Muerta midstream service***

On February 2023, TGS partially commissioned expansion works in the Tratayén plant, installing two gas conditioning modules of 3.5 million m3/day each. It is estimated that the commissioning will be completed during Q2 2023. Consequently, the plant's total conditioning capacity will reach 15 million m<sup>3</sup>/day.

***Board's Appointments***

The shareholders' meeting of Pampa, dated December 27, 2022, approved the appointment of María Renata Scafati as an independent board member, replacing Santiago Fraschina until term completion. Hence, 40% of the Board of Pampa comprises female members.

The 5% increase in power generation **sales** during Q4 22 is mainly explained by higher volumes and prices in legacy energy. Said pricing scheme is denominated in AR$ and had 20% and 10% cumulative increases in September and December 2022, respectively<sup>[6]</sup>, exceeding the nominal depreciation of 20% in Q4 22. The capacity remuneration for our thermal legacy units was US$4.0 thousand/MW-month (+13% vs. Q4 21) and US$2.1 thousand/MW-month for hydros (+10% vs. Q4 21). 73% of the 5,088 MW operated by Pampa<sup>[7]</sup> is composed of legacy energy but represented just 32% of the Q4 22 segment's sales.

Q4 22 sales also increased because of PEMC's consolidation and higher gas volume assigned to CAMMESA as the second CTGEBA's CCGT had a major overhaul in Q4 21. It is worth highlighting that fuel income only applies to PPAs under Energía Plus and SEE Res. No. 287/17, and in turn, the gas purchases to our E&P impact power generation costs. CAMMESA provides the remaining fuel for our thermal units without earning sales or accruing costs.

Those effects were partially offset by lesser PPA income due to contract maturities in CTLL's ST and CTP (remunerated as legacy energy since November and July 2021, respectively) and the export incentive collected in Q4 21 from CAMMESA, discontinued in January 2022. In addition, we recorded an incident in CTLL's GT05 in December 2022, which was put back on service in mid-January 2023.

------

<sup>6</sup> Increases granted in December 2022. For further information, see section 1.1 of this release.

<sup>7</sup> Under IFRS, we do not consolidate CTEB (567 MW) in our financial statements since it is an affiliate. However, it is an asset operated by Pampa and its EBITDA is incorporated to our shareholding to the total adjusted EBITDA.

![](pampr4q226k_009.jpg)

In **operating terms**, Pampa's operated power generation grew 11% vs. Q4 21, while the Argentine power grid recorded a drop of 1%. The higher generation was mainly due to Q4 21's programmed overhauls in CTEB, CTLL's CCGT and second CTGEBA's CCGT, partially offset by CTLL GT05's outage and lesser gas availability in CTGEBA during Q4 22 (+343 GWh). Additionally, the higher output was explained by greater gas availability in CPB (+234 GWh) and better nature conditions in HPPL (+162 GWh) and wind farms (+38 GWh). However, these increases were partially offset by the gas depletion from Bolivia impacted in CTG and CTP (-199 GWh), lower liquid fuels usage in CTIW and CTPP (-43 GWh), and lesser water in HINISA and HIDISA (-32 GWh).

The **availability** of Pampa's operated units reached 96.5% in Q4 22 (+93 basis vs. Q4 21's 95.5%), mainly because of Q4 21's programmed maintenance in CTLL's CCGT and CTGEBA's second CCGT and CPB's outage in Q4 21, partially offset by CTLL's GT05 incident in December 2022. Therefore, the thermal availability rate slightly improved from 95.3% in Q4 21 to 96.1% in Q4 22 (+76 basis points).

**Note**: Gross margin before amortization and depreciation. It includes CTEB, operated by Pampa (50% equity stake).

Without depreciation and amortizations, net **operating costs** rose 5% vs. Q4 21, mainly due to higher gas purchases either for generation or assigned to CAMMESA, and increased labor costs, which outnumbered the AR$ devaluation. Additionally, the lower electricity procured is explained by CTGEBA's Plus unit outage in Q4 21. However, these effects were partially offset by a rise in delay interests from CAMMESA and lower maintenance costs.

**Financial results** from Q4 22 reached a net profit of US$48 million, while in Q4 21, a loss of US$40 million was recorded, mainly due to gains from the holding of financial instruments, partially offset by a raise of interests due to a higher debt stock in AR$ and the PEMC's consolidation, in addition to higher foreign exchange losses from receivables.

**Adjusted EBITDA** from the power generation segment reached US$86 million in Q4 22 (-19% vs. Q4 21), mainly due to the end of CTLL, CTP and CTEB's certain PPAs, CTLL's GT05 outage and the rise of labor costs in US$, partially offset by higher legacy sales, PEMC's consolidation and lower maintenance costs. In addition, the adjusted EBITDA considers CTEB (CTBSA)'s 50% ownership (US$2 million in Q4 22 vs. US$19 million in Q4 21) and PEMC (Greenwind)'s 50% share capital for US$3 million in Q4 21<sup>[8]</sup>. Adjusted EBITDA excludes items such as the commercial interests for late collection, mainly charged to CAMMESA, and PPE's expenses as operating costs.

<sup>8</sup> As of August 12, 2022 PEMC is consolidated into Pampa's financial statemets.

Finally, **capital investments** without CTEB registered US$16 million in Q4 22 (vs. US$32 million in Q4 21), mainly due to the advanced stage of the PEPE IV expansion project. The PEPE VI project was announced after the closing of Q4 22.

**Note:** Net production in Argentina. Gas volume is standardized at 9,300 kilocalories (kCal).

In **operating** terms, total production reached 61.6 kboe/day in Q4 22 (+6% vs. Q4 21 but -10% vs. Q3 22 due to seasonality). **Gas production** reached 9.5 million m<sup>3</sup>/day (+6% vs. Q4 21 and -11% vs. Q3 22), mainly explained by the higher delivery volumes under Plan Gas.Ar, offset by lower exports to Chile. Analyzing by block, El Mangrullo recorded 6.9 million m<sup>3</sup>/day (+9% vs. Q4 21 and -15% vs. Q3 22), comprising 72% of our total gas output. However, this increase was partially offset by lower activity and the natural depletion at Rincón del Mangrullo (0.3 million m<sup>3</sup>/day, -25% vs. Q4 21 and similar to Q3 22). At Río Neuquén and Sierra Chata, the year-on-year production was similar. Still, compared to the previous quarter, Río Neuquén raised 5% its deliveries, while Sierra Chata decreased by 10% due to the demand seasonality.

Our **gas price** in Q4 22 was US$3.9/MBTU (+24% vs. Q4 21 but -20% vs. Q3 22 due to seasonality), mainly driven by exports with prices better than the local market, and to a lower extent, a slight increase in the industrial segment.

In Q4 22, our **gas deliveries** were allocated as follows: 28% as raw material to our thermal power units<sup>[9]</sup> and petchem plants, 23% sold to CAMMESA, 22% to the industrial/spot market, 14% to retail and 13% exported. On the other hand, in Q4 21, 40% of our gas deliveries were sold to the industrial/spot market, 22% was fired at our thermal and petrochemicals plants, 21% was exported, 15% supplied the retail segment, and the rest was sold directly to CAMMESA.

**Oil production** reached 5.7 kbbl/day in Q4 22 (+10% vs. Q4 22 and +5% vs. Q3 22), mainly due to higher foreign demand: 83% of the volume sold in Q4 22 was placed in the domestic market vs. 93% in Q4 21. Production grew at Gobernador Ayala, Los Blancos and Río Neuquén (+0.7 kbbl/day vs. Q4 21), offset by a slight decline of 0.2 kbbl/day at El Tordillo.

Our **oil price** in Q4 22 increased by 14% year-on-year, reaching US$66.9/barrel, mainly explained by the rise of the international Brent reference and the improvement of local prices.

By the end of Q4 22, we accounted for 895 **productive wells** vs. 884 as of December 31, 2021.

Pampa's **proven reserves (P1)** by the end of 2022 amounted to 179 million boe, 14% higher than the 157 million boe recorded by the end of 2021. The higher shale reserve quantification from the Vaca Muerta formation mainly explains this increase, essentially driven by the performance of pilot wells at El Mangrullo and Sierra Chata blocks. During 2022, we tripled the certified shale volume, reaching 44 million boe, comprising 24% of Pampa's P1 reserves (vs. 14 million boe or 9% of the 2021 P1 reserves). The tight gas addition is mainly from El Mangrullo and, to a lesser extent, from Río Neuquén.

Considering the production levels and additional reserves achieved in 2022, the replacement ratio amounted to 2.0, and the average reserve life was approximately 8.0 years. Moreover, 94% of the reserves are natural gas and 6% oil.

Net **operating costs** in Q4 22, excluding depreciation, amortization and Plan Gas.Ar compensation grew 10% vs. Q4 21, mainly because of the higher activity (treatment and transportation), royalties, levies and taxes from higher price and volume sold, as well as increased costs in labor, partially offset by the reclassification of PPE made in Q4 21 well repair campaign to production cost. Compared to Q3 22, net operating expenses decreased by 12%, mainly due to seasonality (royalties and lower activity) and oil stock consumption in Q3 22, partially offset by the higher transportation cost of exported gas. As a result, lifting cost reached US$7.0/boe produced in Q4 22 (-3% vs. Q4 21 but +5% vs. Q3 22).

**Financial results** in Q4 22 recorded a net loss of US$33 million (+27% vs. Q4 21), mainly due to higher losses from devaluation over receivables and the Plan Gas.Ar's subsidy component, in addition to the increased interests from the higher stock of AR$-debt, partially offset by gains from holding financial securities.

Our oil and gas **adjusted EBITDA** amounted to US$72 million in Q4 22 (+57% vs. Q4 21), mainly explained by the increased deliveries under Plan Gas.Ar, gas exports to Chile and better oil production and prices. These effects were partially offset by higher expenses related to the growing activity and increased royalties and payroll. The adjusted EBITDA of Q4 22 excludes the impairment of inventories.

Finally, in Q4 22, **capital expenditures** amounted to US$114 million (+70% vs. Q4 22), mainly driven by the growing commitments under Plan Gas.Ar.

The petrochemicals segment's **adjusted EBITDA** reached US$15 million in Q4 22 (+68% vs. Q4 21), mainly explained by the rise in local price and demand of reforming products, in addition to the lower costs of virgin naphtha and higher domestic sales of polystyrene, partially offset by lower margin and demand of styrene and SBR. The adjusted EBITDA excludes the impairment of inventories. The adjusted EBITDA fell 21% quarter-on-quarter, mainly due to lower reforming prices and decreased SBR volume sold, partially offset by off-peak gas costs.

Total **volume** sold grew 5% vs. Q4 21 to 120 thousand ton, mainly explained by local demand hike of octane bases associated with the recovery in gasoline consumption, offset by lower export of gasoline and sales of styrene products. Moreover, in Q4 21, 6 thousand ton of bases and gasoline were dispatched as toll processing, which was not recorded as volume sold.

The holding and others segment, without considering the affiliates' equity income (Transener and TGS), posted a US$27 million **operating profit,** while in Q4 21, it was a US$3 million loss, mainly explained by the arbitration award obtained in Ecuador for US$37 million, in addition to lower fees to third parties, partially offset by the updated executive compensation and lower accrued fees.

In Q4 22, **financial results** reached a net gain of US$44 million, while in Q4 21, it was a net loss of US$7 million, mainly due to FX difference gains over tax debt, partially offset by higher tax interests.

The **adjusted EBITDA** of our holding and others segment decreased by 74%, recording US$10 million in Q4 22. The adjusted EBITDA excludes the equity income from our participation in TGS and Transener. In turn, it adds the EBITDA adjusted by equity ownership in these businesses. Besides, it excludes the impairment of intangible assets and Ecuador's award in Q4 22.

In **TGS**, the EBITDA adjusted by our stake was US$22 million in Q4 22 vs. US$39 million in Q4 21. The decline in the total adjusted EBITDA was mainly due to lower international reference prices and regulated income (although tariffs were increased in March 2022, they failed to offset the evolution of AR$ devaluation), in addition to the higher cost of gas in US$, used to replace thermal reduction at Cerri. However, these effects were partially offset by ethane price hikes, higher dispatched liquid volume and lower maintenance costs.

In **Transener**, the EBITDA adjusted by our stake recorded a loss of US$2 million in Q4 22 vs. a gain of US$2 million in Q4 21, mainly because the AR$ devaluation outnumbered the tariff increase.
