1.         Consolidated Results

The consolidated result is made up of Copel (Holding), Copel Geração e Transmissão (GenCo), Copel Distribuição (DisCo), Copel Comercialização (TradeCo) and other equity holdings^[1]^ . The following analyses refer to the second quarter of 2025 (2Q25) compared to the same period in 2024 (2Q24) and, where applicable, to the accumulated periods of the first six months of 2024 and 2025 (1H24 and 1H25, respectively).

1.1 Ebitda

Copel Recurring Ebitda^[2]^ amounted R$ 1,335.0 million in 2Q25, 4.2% higher than the R$ 1,281.0 million recorded in 2Q24, reflecting the good performance and resilience of our assets and the Company's operational and commercial efficiency. GenCo and TradeCo accounted for approximately 58.4% of this result, while DisCo accounted for 42.6%.^[3]^

Highlights in 2Q25 include:

(i) GenCo's Ebitda, which grew by 12.6% (+R$ 85.1<br>million) compared to 2Q24, totaling R$ 761.4 million, mainly because of the following factors: i. an<br>increase of R$ 45.4 million, due to better results in transactions carried out<br>on the short-term market; ii. an increase of 17.2% in<br>wind power generation caused by a wind volume above certification, enabling a lower deviation<br>of R$ 18.9 million (-45.8% compared to 2Q24), despite the higher curtailment between<br>periods (12.1% vs. 7.6% in 2Q24); iii. R$ 16.9 million increase in revenue from the availability of the electricity grid,<br>explained mainly by the incorporation of the Mata de Santa Genebra S.A. (MSG) transmission company; and iv. Ebitda from discontinued<br>operations, which was negative R$ 13.8 million in 2Q24, absent in 2Q25;
(ii) a 98.0% increase (+R$ 8.4 million) in Elejor's<br>EBITDA compared to 2Q24, due to higher energy sales for bilateral contracts and average energy balance prices 17.4% higher between the<br>periods;
--- ---
(iii) DisCo' Ebitda, which increased by 0.6% (+R$ 3.1 million)<br>compared to 2Q24, mainly due to the June 2024 tariff readjustment, with an average increase of 2.7% in the Distribution System Use Tariffs<br>(TUSD), partially offset by the 2.6% drop in the billed grid market, a consequence mainly due to milder weather, which had a negative<br>impact on consumption in the residential and commercial segments, and by the increase of R$ 126.3 million (+33.1%) in the cost of<br>energy purchased for resale, due to the higher volume coming from the Distributed Micro and Mini Generation (MMGD) compensation system;<br>and
--- ---
(iv) a 3.7% (-R$ 27.6 million) reduction in manageable<br>costs (PMSO), mainly influenced by the dismissal of 1,436 employees, mostly through the Voluntary Dismissal Program (PDV) completed in<br>2024, partially offset by the pro rata provision, between October and December, of the 2024 Collective Bargaining Agreement, with<br>a 4.09% salary adjustment (INPC accumulated over 12 months up to September 2024) and by a 9.7% increase in third-party services, mainly<br>for maintenance of the electrical system at DisCo.

^[3]^ Holding, Copel Serviços and Elejor accounted for -1.0% of recurring Ebitda.

This result was partially offset by the decrease of R$ 16.6 million (-47.5%) in TradeCo's Ebitda, basically due to the lower sales margin, of R$ 15.3 million, and the Ebitda from discontinued operations, of R$ 31.0 million, recorded at Copel (Holding) in 2Q24 and absent in 2Q25.

1.2 Operating Revenue

Net Operating Revenue totaled R$ 6,225.2 million in 2Q25, up 13.6% on the R$ 5,479.3 million recorded in 2Q24. This result is mainly the result of increases:

(i) R$ 414.1 million (+57.0%) in electricity<br>supply revenue, with the following highlights: i. R$ 262.6 million increase in TradeCo (excluding revenue from group companies),<br>due to the 36.0% growth in the volume of energy sold to bilateral contracts; ii. an increase<br>of R$ 45.4 million at GenCo, due to the better result in transactions carried out on the short-term market in<br>2Q25 compared to 2Q24, especially the modulation of the hydroelectric generation portfolio in view of the behavior of the PLD in<br>the South submarket in the period; iii. lower<br>generation deviation, of R$ 18.9 million (-45.8%), in the wind complexes; iv. an<br>increase of R$ 54.9 million in DisCo revenue due to the higher sale of energy in the short term (MCP); and v. an increase<br>of R$ 9.5 million in the energy sold by Elejor for bilateral contracts;
(ii) R$ 377.3 million (+188.7%) in the result<br>of sectorial financial assets and liabilities (CVA), because of the adherence of tariff coverage in relation to costs with Parcel A, especially<br>with energy purchased for resale and the return of PIS/COFINS to DisCo consumers in the period;
--- ---
(iii) R$ 168.4 million (+25.0%) in construction<br>revenue, mainly due to the increase in the volume of works related to DisCo's investment program (see topic 2), which includes investments<br>aimed at improving and modernizing infrastructure and improving customer service; with no effect on the result given that the amount recorded<br>in costs and expenses is equal; and
--- ---
(iv) R$ 91.3 million (+77.6%) in other revenues,<br>especially due to the R$ 61.2 increase in the fair value of TradeCo's energy purchase and sale contracts (Marked to Market - MTM)<br>(which was mainly influenced by the reduction in the long-term NTN-B discount rate and the reduction in the submarket spread) and<br>the R$ 28.4 million increase in revenue from DisCo's infrastructure sharing rents and contractual fines.
--- ---

These increases were partially offset by:

(v) the decrease of R$ 167.5 million (-8.1%)<br>in electricity supply revenue, due to: i. the reduction of R$ 91.7 million at DisCo due to the 10.2% drop in the captive market<br>billed, due to the lower temperature in the period and greater MMGD compensation, as well as the negative tariff adjustment of 4.0% in<br>the Energy Tariff (TE) in the 2024 Annual Tariff Review; and ii. the drop of R$ 75.9 million at TradeCo due to the 5.5% reduction<br>in energy sold to free consumers; and
(vi) the<br>decrease of R$ 136.3 million (-8.2%) in revenue from the availability of the electricity grid, mainly explained by: i. the<br>reduction of R$ 86.7 million in DisCo due to the 0.7% drop in the wire market, due to milder temperatures in the period; and ii.<br>a decrease of R$ 115.1 million, due to Aneel's decision to recalculate the financial component of the Existing System Basic Network (RBSE);<br>partially offset: iii. by an increase of R$ 39.0 million due to the partial granting of an administrative appeal requesting the<br>recalculation of the July 2024 tariff review amounts for transmission contracts; iv. by the consolidation of revenue of R$ 30.9<br>million from MSG, as of June 1, 2025; and v. by the adjustment of transmission contract asset balances, mainly due to the increase<br>in the IPCA.
--- ---

1.3 Operating Costs and Expenses

In 2Q25, operating costs and expenses totaled R$ 5,067.9 million, an increase of 9.9% compared to R$ 4,611.6 million recorded in 2Q24. In this regard, the following stand out:

(i) the increase of R$ 550.5 million (+27.3%) in<br>electricity purchased for resale, mainly due to: i. the increase of R$ 185.5 million in the purchase of energy from DisCo on the<br>Energy Trading Chamber (CCEE) and the higher volume from the distributed generation system (+R$ 126.3 million); ii. an increase<br>of R$ 224.9 million (+27.5%) at TradeCo, mainly due to the acquisition of electricity under bilateral contracts; and iii. growth<br>of R$ 70.8 million in purchases on the short-term market (MCP), given a lower average GSF (95.3% compared to 99.3 in 2Q24), partially<br>offset iv. by an increase of R$ 56.5 million (+11.5) in eliminations and reclassifications of purchases made between groups;<br>and
(ii) an increase of R$ 168.4 million (+25.0%) in<br>construction costs, mainly due to Copel DIS's investment program, with no effect on results given the matching of the amount recorded<br>in construction revenue.
--- ---

This result was partially offset by:

(i) a R$ 42.5 million (-6.5%) reduction in electricity<br>network usage charges, mainly due to the increase in the share of the locational signal in the calculation of the TUST in the generation<br>segment (-R$ 20.1 million) and lower costs with the Basic Network and Transportation from Itaipu in the distribution segment due to lower<br>tariffs approved by ANEEL (-$ 30.3 million); and
(ii) lower PMSO costs (excluding provisions, reversals<br>and the effects of the partial disposal and swap of assets), which fell by R$ 27.6 million (-3.7%), due to the reduction in the number<br>of employees, partially offset by an increase of R$ 24.7 million (+9.7%) in third-party services, mainly due to an increase of R$ 23.7<br>million in expenses with maintenance of the electrical system at Copel DIS.

Neutralizing the effects of provisions related to performance bonuses (PPD), profit sharing (PLR), long-term incentives (ILP) and PDV, there was a reduction of R$ 40.8 million (-17.5%) in personnel and management costs in the quarterly comparison, because of the reduction in the total number of employees in the comparison between the periods, partially offset by the pro rata provision between October and December of the collective bargaining agreement - ACT 2024, with a salary readjustment by the National Consumer Price Index - INPC, of 4.09%, considering 12 months until September/2024.

1.4 Equity Income Results

The equity income from jointly controlled companies and other affiliates of Copel in 2Q25 decreased by 20.2% compared to the same period last year (R$ 64.3 million, compared to R$ 80.5 million recorded in 2Q24). The decrease is mainly due to the consolidation of 100% of Mata de Santa Genebra S.A. - MSG, as of June 1, 2025, with a reduction of approximately R$ 5.5 million in this item, and by the decrease in the restatement of contract assets in the transmission segment, caused by lower inflation in the period (IPCA of 0.93% vs. 1.05% in 2Q24). Details of the results can be found in Annex I.

1.5 Financial Results

The financial result was a negative R$ 401.9 million in 2Q25, compared to a negative R$ 289.7 million in 2Q24, an increase of R$ 112.2 million (38.7%). This variation is mainly due to the increase in expenses with charges and monetary variation of R$ 213.3 million (+48.9%), due to the increase in debt and the CDI (Copel's main debt indexer) in a higher interest rate environment. These effects were partially offset by an increase of R$ 31.6 million in interest on taxes to be offset, essentially due to the updating of PIS/COFINS, and by an increase of R$ 52.2 million in other financial income, mainly due to the updating of the adjustment to present value of the Use of Public Property - UBP.

Total Financial Result (401.9) (289.7) 38.7 (848.4) (557.9) 52.1

1.6 Consolidated Net Income

Copel recorded reported net income of R$ 573.6 million in 2Q25, compared to R$ 473.6 million in 2Q24, an increase of 21.1%, mainly due to improved operating performance, with emphasis on the increase in the results of the hydroelectric and wind power portfolios, as well as the reduction in personnel costs and net gains of R$ 132.3 million from the disposal and swap of assets in 2Q25, partially offset by the lower financial result identified in the previous section and by the 25.9% increase in income tax/social contribution (IR/CSLL), mainly due to operating performance and gains from the disposal and swap of assets.

4

The main adjustments to net income in 2Q25 were:

Excluding non-recurring effects and non-cash items (VNR, MTM and IFRS in broadcasters) in 2Q25, Recurring Net Income decreased by 9.5% compared to 2Q24. This was substantially influenced by the R$112.2 million decline in financial results, as highlighted in section 1.5, which was partially offset by improved operating performance, with a R$ 54.0 million increase in recurring Ebitda, and a 12.1% reduction in IR/CSLL, due to the lower calculation basis resulting from the decline in financial results.

1.7 Indebtedness

Copel's total consolidated debt on June 30, 2025 was R$ 20,037.4 million, a variation of 12.9% in relation to the amount recorded on December 31, 2024, of R$ 17,753.8 million. The following table and graphs show the indebtedness of Copel and its subsidiaries as of June 30, 2025.

On June 30, 2025, consolidated leverage reached 3.1x, reflecting a net debt of R$ 16,563.7 million - an increase of 0.5x compared to the end of 2024. Despite the increase, the indicator remains within the parameters defined by the optimal capital structure. The increase is mainly attributable to the conclusion of the acquisition of 70% of the Baixo Iguaçu HPP, with a cash outflow of R$ 1.0 billion, in the context of the asset divestment process. Excluding the effects of this transaction, leverage ended the period at 2.9x.

Of the amount invested in DIS in the quarter, 82.0% was allocated to investments in electrical assets and 18.0% to non-electrical assets and other investments. The funds were allocated mainly under the Paraná Trifásico and Rede Elétrica Inteligente projects, with the aim of modernizing, automating and renewing the distribution network, with standardized technologies for automation equipment. Among the benefits of the projects are the reinforcement of rural networks to reduce disconnections and ensure support for the growth of agribusiness in the state of Paraná, the reduction of costs with O&M and commercial services and the improvement in the control of the indicators of Equivalent Duration of Interruption per Consumer Unit - DEC and Equivalent Frequency of Interruption per Consumer Unit - FEC. The program is made up of pillar projects:

Paraná Trifásico (ParanáThree-Phase): covers the construction of approximately 25,000 km of new networks by 2025 and represents the improvement and renovation<br>of rural distribution networks in the company's concession area, with the implementation of a three-phase network and the creation of<br>redundancy in the main rural branches. By late June 2025, 22,996 km of network had been completed.
Rede Elétrica Inteligente (SmartGrid): aims to implement a private communication network with standardized technology to serve all the distribution network's automation<br>equipment and advanced metering infrastructure. By late June 2025, 1,519,502 smart meters had already been installed. Phases 1, 2 and<br>3 of the program identified advances for our operation, with a reduction in man-hours and km traveled, less non-technical losses, improved<br>quality and a reduction in compensation for breaches of quality performance limits.

3.1 Economic and Financial Performance

GenCo reported recurring Ebitda^[4]^ of R$ 761.4 million, 12.6% higher than the R$ 676.3 million recorded in 2Q24.

This result mainly reflects:

**(i)**the increase of R$ 45.4 million, resulting from the positive effects on transactions carried out in the short-term market, especially the modulation of the hydroelectric generation portfolio in the face of the behavior of the PLD in the South submarket in the period;

**(ii)**the 17.2% increase in wind power generation (799 GWh, compared to 682 GWh in 2Q24), mainly due to the volume of wind above certification, enabling a lower generation deviation of R$ 18.9 million

(-45.8%), despite the increase in curtailment, which went from 7.6% in 2Q24 to 12.1% in 2Q25;

**(iii)**the increase of R$ 17.3 million in revenue from Energy Purchase Contracts in the Regulated Environment - CCEAR, essentially due to the start of supply from Jandaíra;

**(iv)**higher revenue from grid availability, of R$ 16.9 million, mainly due to the incorporation of the Mata de Santa Genebra S.A.

  • MSG transmission company;

**(v)**a reduction of R$ 20.1 million in charges for the use of the electricity grid, due to the increased participation of the locational signal in the calculation of TUST;

**(vi)**the decrease of R$ 10.3 in the cost of PMSO; and

**(vii)**the negative Ebitda from discontinued operations of R$ 13.8 million present in 2Q24 and not in 2Q25.

The positive effects mentioned above were partially offset by the R$ 70.8 million increase in the cost of electricity purchased for resale, because of the higher PLD between the periods.

Neutralizing the effects of the provisions relating to the PDV, PPD and PLR, there was a 33.3% reduction in personnel and management costs compared to 2Q24, reflecting the already mentioned reduction in the workforce between the periods, partially offset by the pro rata provision, between October and December, for the 2024 Collective Bargaining Agreement, with a salary adjustment of 4.09% (INPC accumulated over 12 months up to September/2024).

Recurring Net Income reached R$ 292.5 million in 2Q25, down 19.7% compared to 2Q24. This result mainly reflects the combination of the following effects: i. negative variation in the financial result (-R$ 236.5 million in 2Q25, compared to -R$ 146.4 million in 2Q24), explained by the higher amount of debt and higher CDI (3.3% in 2Q25, compared to 2.6% in 2Q24); ii. higher expenditure on Income Tax and Social Contribution, of R$ 81.9 million, due essentially to the payment of Interest on Own Capital (JCP) to Copel (Holding), which occurred in 2Q24 and not in 2Q25; iii. Higher Ebitda, by R$ 85.1 million, due to the points presented above; **iv.**Reduction in depreciation, by R$ 28.7 million, due to the renewal of concessions and the reclassification of assets held for sale; and v. Decrease in Others, including equity accounting, by R$ 15.3 million, mainly due to the consolidation of Mata de Santa Genebra - MSG into the portfolio, which ceased to contribute to equity income in the amount of R$ 9,4 million.

*Results from discontinued operations and equity income

In the year to date, GenCo recorded Recurring Ebitda of R$ 1,544.5 million, an increase of 13.2% over the same period last year, mainly due to: i. the higher average energy price of GenCo's portfolio in the year; ii. the lower generation deviation in the wind complexes; and iii. the reduction in personnel costs, due to the reduction in the workforce; partially offset by the higher expenditure on electricity purchased for resale.

3.2 Operational Performance

With a presence in 10 states, GenCo operates a diversified park of hydroelectric and wind power plants, totaling 6,227.0 MW^[5]^ of installed power and 2,696.2 MW of average physical guarantee. In the Transmission segment, Copel has a total network of 9,684 km of transmission lines and 53 basic network substations, considering its shareholdings.

For more information on generation and transmission businesses operating data, see Annex IV.


^[5]^ Does not include HPP Baixo Iguaçu, which is in the process of being sold.

3.2.1 Generation

Copel's generation park is made up of 100% renewable operating sources.

GenCo's hydroelectric generation was 49.4% lower in 2Q25 (2,726 GWh, compared to 5,389 GWh in 2Q24), caused by a less favorable hydrological scenario and divestment in Small Hydroelectric Plants and the Colíder HPP. In wind farms, generation was 17.2% higher in 2Q25 (799 GWh, compared to 682 GWh in 2Q24), despite the increase in curtailment in 2Q25 (12.1%, compared to 7.6% in 2Q24) and the unavailability of some machines. In the year to date, the total generation of the company's portfolio was 41.9% lower (3,525 GWh in 1H25, compared to 6,071 GWh in 1H24).

3.2.2 Energy sold

In the 2nd quarter of 2025, GenCo recorded 3,708 GWh of electricity sold from hydroelectric sources, a reduction of 8.2%, mainly due to divestments in the SHPs and HPP Colíder. Consequently, this led to an increase in the amount of energy purchased on the short-term market (MCP). The energy sold does not consider the generation allocated to the Energy Reallocation Mechanism (MRE), which fell by 85.6% in the quarter (220 GWh, compared to 1,527 GWh in 2Q24), reflecting the hydrological conditions in the period.

For wind farms, the total electricity sold was 1,177 GWh, an increase of 11.7%, mainly due to the increase in sales under bilateral contracts and energy sold in the regulated environment (CCEARs), due to the start of supply at the Jandaíra Complex^[6]^.

3.2.3 Transmission

Copel has more than 9,600 km of transmission lines in eight Brazilian states, including its own assets and those in partnership with other companies. In addition to building, maintaining and operating its own extensive energy transmission network, Copel provides services for projects run by other concessionaires. The Transmission projects are listed in Annex IV, including the projects of GenCo, SPEs Costa Oeste, Marumbi, Uirapuru Transmissora and MSG (100% GenCo), as well as the 6 SPEs in which GenCo has a stake.

RBSE

Below is a description of the flow of the portion of the Revenue relating to the Basic Network of the Existing System - RBSE^[7]^ for the next few cycles. It is important to note that the data may be altered in the future due to tariff revision processes and/or revision of the parameters used to compose these revenues by the regulatory body. The figures below include the revision in the methodology for calculating the financial component, established by Aneel’s homologating resolution no. 3,467/2025, with a negative impact of R$ 115.1 million, and have been adjusted annually by the IPCA, according to Aneel’s homologating resolution no. 3,481/2025.

4. Copel Distribuição - DisCo

4.1 Economic and Financial Performance

DisCo reported recurring Ebitda of R$ 569.3 million in 2Q25, up 0.6%, mainly due to the June 2024 tariff adjustment, with an average increase of 2.7% in TUSD, partially offset by a 2.6% decline in the billed wire market. The following also contributed to the result:

(i) a R$ 53.0 million increase in DisCo's supply revenue,<br>with a 2.0% growth in consumed energy;
(ii) a R$ 21.7 million increase in other revenues, mainly<br>from infrastructure sharing rentals and contractual fines;
--- ---
(iii) a R$ 18.6 million reduction in PMSO, due to the dismissal<br>of 1,026 employees, mostly under the Voluntary Dismissal Program concluded in 2024, partially offset by an increase in third-party service<br>costs.
--- ---

These results were partially offset by an increase of R$ 18.4 million in provisions and reversals due to an increase of R$ 12.1 million in Estimated Losses on Doubtful Accounts - PECLD, mainly related to defaults in the low voltage group, and an increase of R$ 6.3 million in litigation, especially due to legal proceedings.

For the year to date, recurring Ebitda reached R$ 1,262.2 million, an increase of 6.7%.

Expenses with manageable costs (PMSO), excluding provisions and reversals, fell R$ 18.6 million (-4.0%) compared to 2Q24, mainly because of the reduction: i. of R$ 32.0 million (-28.4%) in the cost of personnel, administrators, social security and assistance; ii. of R$ 11.3 million (-17.9%) in other costs and expenses, essentially due to the recovery of taxes, in the amount of R$ 8.3 million, and a reduction of R$ 6.5 million in indemnities, mainly administrative reimbursements; and iii. of R$ 6.5 million (-38.7%) in materials expenses, basically from stock clearance and control and a reduction in fuel, parts and equipment costs for the company's fleet.

These effects were partially offset by an increase of R$ 31.2 million (+18.4%) in third-party service costs, due to a greater number of contracts and demands, mainly for maintenance services for the electricity system (+R$ 23.7 million) and cleaning of the right-of-way (+R$ 2.0 million), as well as an increase of R$ 4.7 million in losses on the decommissioning of assets, due to the investment program, mainly with the Smart Grid project.

In the year to date, manageable costs increased by 0.5%, mainly due to the growth in third-party service costs in 2t.

Disregarding the effects of the provisions for the Voluntary Dismissal Program (PDV), performance bonuses (PPD) and profit sharing (PLR), personnel costs fell by 21.9%, mainly reflecting the decrease in salaries, charges and expenses with the social security and assistance plans, as a result of the reduction of 1,026 employees in the company's own staff, mainly due to the PDV, as previously mentioned, partially offset by the provision pro rata, between October and December, of the 2024 Collective Bargaining Agreement, with a salary adjustment of 4.09% (INPC accumulated over 12 months until September 2024).

4.2 Operational Performance

4.2.1 Grid Market (TUSD)

In the second quarter of 2025, electricity consumption in DisCo's grid market fell by 0.7% compared to the same period last year. This decline was mainly influenced by the milder temperatures observed throughout the period, which reduced demand for energy in the residential and commercial sectors. On the other hand, the industrial sector showed a positive performance, helping to mitigate the downturn in total consumption and showing the resilience of economic activity in Copel's concession area. The billed wire market, which considers energy compensated by Mini and Micro Distributed Generation (MMGD), fell by 2.6% in 2Q25 and 0.9% year-to-date.

4.2.2 Captive Market

The captive market recorded a 10.2% drop in electricity consumption in 2Q25 compared to the same period last year, mainly influenced by the milder temperatures which had a negative impact in the residential sector, and a 6.2% drop year-to-date. The billed captive market, which includes MMGD compensated energy, fell by 14.9% in 2Q25 and by 10.9% in the year to date.

4.2.3 Operational data

DisCo has a concession in force until 07.07.2045, whose service quality criteria (Equivalent Interruption Duration per Consumer Unit - DEC and Equivalent Interruption Frequency per Consumer Unit - FEC) are defined by Aneel.

Despite the severe weather events in the state of Paraná in recent months, the company has acted in a timely manner to re-establish the power supply and prevent vegetation on the network, which has contributed to maintaining the quality-of-service indices within the regulatory limits.

For DEC, the result for the last 12 months as of June 2025 was 7.49 hours, while for FEC, the result for the same period was 4.94 interruptions, both within the established regulatory limit.

Losses- Distribution losses can be defined as the difference between the electricity acquired by distributors and that billed to their consumers and are segmented as Technical and Non-Technical. Technical Losses are inherent to the activity of electricity distribution and Non-Technical Losses originate mainly from theft (clandestine connection, direct detour from the network), fraud (meter tampering or detour), reading, measurement and billing errors. At the end of June 2025, Technical Losses in the last 12 months were 2,291 GWh, compared to 2,230 GWh in the same period last year, and Non-Technical Losses were 716 GWh, compared to 874 GWh in the same period last year. Total losses over the last 12 months amounted to 3,007 GWh.

GWh - 12 Months Jun-21 Jun-22 Jun-23 Jun-24 Jun-25*

Technical losses 2,056 2,029 2,052 2,230 2,291
Non-technical losses 637 665 645 874 716

*As established by the result of CP 09/2024 (DSP No. 1,220/2025)

Non-Technical Losses, calculated as the difference between total losses and technical losses, are largely associated with the concessionaire's management and the socio-economic characteristics of the concession areas. To this end, Copel maintains a Program to Combat Non-Technical Losses, through the following actions, among others:

use of smart meter<br>alarms to improve the performance of selected targets;
improving actions to<br>combat irregular procedures, improving the performance of targeted inspections;
--- ---
investments in the<br>provision and/or acquisition of inspection equipment;
--- ---
preparing and carrying<br>out specific training and retraining related to commercial losses;
--- ---
carrying out inspections<br>on both medium and low voltage;
--- ---
educational notices<br>in the press and messages on electricity bills;
--- ---
joint operations with<br>the Civil Police and the Public Prosecutor's Office; and
--- ---
the opening of police<br>investigations in regions where significant numbers of irregular procedures have been found.
--- ---

The tariff transfer of efficient levels of losses is provided for in the concession contracts and these losses are included in energy purchase costs up to the regulatory limit stipulated by Aneel. DisCo has remained within the regulatory limits in recent tariff processes and in June 2025, total losses were 0.55% below the regulatory limit, influenced by the revision of targets resulting from the effects of CP 09/24.

5.1 Economic and Financial Performance

TradeCo reported recurring Ebitda of R$ 18.3 million in 2Q25, down 47.5% on the figure of R$ 34.9 million in 2Q24, mainly due to a reduction in the sales margin of approximately R$ 15.3 million.

The main adjustment in the quarter was the fair value of the energy purchase and sale contracts (mark-to-market), calculated as the difference between the contracted price and the future market price estimated by the company - which was positive by R$ 61.2 million in 2Q25 compared to a negative R$ 31 million in 2Q24, influenced mainly by the negative mark-to-market in the period, plus the change in the profile of the base contracts, the reduction in the NTN-B discount rate in the long term and the spread reduction in the Northeast submarket.
