**AXIA ENERGIA RELEASES FOURTH QUARTER 2025 RESULTS**

**4Q25 Main Events**

**4Q25 results**: The quarter reflected positive effects from energy sales, resulting in improved generation contribution margins, lower Personnel, Materials, Services, and Other (PMSO) expenses, expanded transmission margins, and reduced provision volumes. These advances evidenced the strategy of optimizing the energy portfolio, the continuous pursuit of operational efficiency, and consistent action in mitigating contingencies.

**Rebranding*:*** In October 2025, the Company announced a new chapter in its trajectory as the largest clean energy company in the Southern Hemisphere with the launch of the AXIA Energia brand, representing a future vision of a company guided by financial discipline, operational excellence, and consistent value creation.

**Extinction of the Direct Action of Unconstitutionality (ADI) 7,385:** On December 11, 2025, the Supreme Federal Court (STF) ratified the Settlement Agreement between the Company and the Federal Government within the Federal Administration's Mediation and Conciliation Chamber (CCAF), thereby extinguishing the ADI.

**Stock bonus:** In December 2025, the Company approved the capitalization of R$30 billion from profit reserves through the issuance of Class C preferred shares (PNC) as a stock bonus. Additionally, the Company created immediately and compulsorily redeemable preferred shares (PNR) for holders of Class A and B preferred shares to enable payment of the premium to which preferred shareholders are entitled.

**Portfolio management:** Management delivered significant and consistent milestones in October, accelerating the Company's streamlining and de-risking efforts. Key transactions include:

&nbsp;&nbsp;&nbsp;&nbsp;▪ Completion of
the sale of the Santa Cruz TPP, the last thermal asset. With this transaction, AXIA Energia now holds a 100% renewable portfolio, aligned
with its Net Zero 2030 commitment

&nbsp;&nbsp;&nbsp;&nbsp;▪ Execution of
the sale agreement for Eletronuclear

&nbsp;&nbsp;&nbsp;&nbsp;▪ Execution of
the acquisition agreement for Tijoá Energia

In addition, we completed the sale of EMAE stake in January 2026.

**Investments:** R$3,869 million in 4Q25, up by 43% and 28% compared to 3Q25 and 4Q24, respectively. It is worth noting the 57% YoY increase in transmission segment investments in reinforcements and improvements, which reached R$1,992 million in the quarter and the annual record of R$4,757 million in 2025.

Still within the transmission segment, 224 large-scale projects are under implementation, representing an additional RAP of R$1.8 billion between 2025 and 2030 with a total estimated CAPEX of R$14.0 billion.

**Financial management:** net debt totaled R$46,484 million in 4Q25, up by R$3,908 million and R$8,814 million compared to 3Q25 and 4Q24, respectively. This increase was due to the higher gross debt and lower available cash, resulting from the R$4.3 billion dividend payment in December 2025, which consumed a portion of the R$4.1 billion in free cash generated during the period. The average debt maturity decreased by 3.6 months while the average cost rose to CDI + 0.63% p.a. in 4Q25 from CDI + 0.07% p.a. in 4Q24, reflecting a 275 bps increase in the benchmark interest rate (Selic).

Capital raising transactions worth highlighting:

&nbsp;&nbsp;&nbsp;&nbsp;▪ Axia Norte raised
R$2 billion and Axia Energia raised R$1 billion through debenture issuances in December 2025

&nbsp;&nbsp;&nbsp;&nbsp;▪ Axia Energia
raised R$2 billion through debenture issuance in February 2026

**Compulsory loan:** the provision inventory was reduced by R$2.6 billion YoY and R$663 million sequentially, totaling R$11.1 billion in 4Q25. Agreements reached and favorable decisions led to a net reversal of R$138 million in the quarter.

![](image_003.jpg)

**4Q25 Financial Highlights**

**Adjusted regulatory net revenue:** R$9,915 million in 4Q25, down 5.5% YoY, reflecting lower generation revenue due to the sale of thermal power plants and the R$250 million negative impact from wind farm reimbursements, partially offset by the higher transmission revenue. On a sequential basis, the increase in generation revenue partially offset the decline in transmission revenue, which was explained by lower collection of items that will be compensated through PA in the following cycle, amounting to R$225 million.

**Contribution margin from generation, ACL + MCP:** The contribution margin from energy traded in the Free Contracting Environment (ACL) and settled in the Short Term Market (MCP) increased to R$101/MWh in 4Q25 from R$78/MWh in 4Q24, considering the resources available for allocation in both segments.

**Contribution margin from transmission:** R$3,924 million in 4Q25, up 3.1% vs. R$3,805 million in 4Q24, mainly reflecting the lower PA in the current tariff cycle. Sequentially, when compared to the R$4,187 million recorded in 3Q25, the R$263 million decrease in the contribution margin was mainly explained by the R$225 million mentioned above (additional information on page 25).

**Adjusted PMSO:**

&nbsp;&nbsp;&nbsp;&nbsp;▪ **IFRS**:
R$1,763 million in 4Q25, down 14.4% compared to R$2,060 million in 4Q24.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Regulatory**:
R$1,761 million in 4Q25, down 15.9% compared to R$2,093 million in 4Q24.

&nbsp;&nbsp;&nbsp;&nbsp;▪ Two key events
in the quarter impacted both IFRS and regulatory frameworks:

&nbsp;&nbsp;&nbsp;&nbsp;▪ R$108 million
related to changes applied to the Profit Sharing (PLR) and Long-Term Incentive programs (ILP) at the end of 4Q25 to reinforce the alignment
between performance, value generation and the Company's strategic priorities

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ R$60 million
in rebranding expenses related to the AXIA Energia brand launch announced in October

**Adjusted Provision:**

&nbsp;&nbsp;&nbsp;&nbsp;▪ **IFRS**:
R$129 million provision in 4Q25, compared to a R$406 million provision in 4Q24.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Regulatory**:
R$147 million provision in 4Q25, compared to a R$150 million provision in 4Q24.

**Adjusted Regulatory EBITDA** **:** EBITDA reached R$5,745 million in 4Q25, up 12.9% YoY, delivering consistent evolution, driven by:

&nbsp;&nbsp;&nbsp;&nbsp;▪ A 5.8% increase
in transmission revenues

&nbsp;&nbsp;&nbsp;&nbsp;▪ A 15.9% drop
in PMSO expenses, reflecting the continuous pursuit of operational efficiency

&nbsp;&nbsp;&nbsp;&nbsp;▪ A 28.9% increase
in equity income, even excluding Eletronuclear and EMAE

These advances more than offset the 12.4% decrease in generation revenue.

(1) Pass-through items that will be compensated through the Adjustment Portion (PA) in the following cycle.

(2) Rebranding expense was R$60 million in 4Q25 and R$1 million in 3Q25, summing up to R$61 million in 2025.

**Income and Social Contribution Taxes on Net Income, IFRS:** The highlight in 4Q25 was the recognition of R$12,362 million in deferred tax assets, explained by changes in estimates of future taxable income. It is worth noting that the amount of R$2,493 million, relating to non-operating results, remains unrecognized.

**Adjusted IFRS Net Income:** Reached R$1,251 million, up 141% YoY, driven by lower PMSO expenses, reduced provisions, and decreased income tax and social contribution expenses, which more than offset the decline in generation contribution following thermal plant divestments.

(1) The figures in both lines relating to 4Q24 presented in this report show two differences compared to those originally disclosed on March 13, 2025. While gross transmission revenue decreased by R$209 million, from R$4,419 million to R$4,210 million, the cost of network usage charges, recorded under Energy Resale, Grid, Fuel and Construction, also decreased by R$209 million, from R$3,757 million to R$3,528 million. Therefore, the net effect on EBITDA and net income is nil. The change in both line items stems from a 2025 revision of accounting practices for eliminations of transactions between the Company's generation and transmission segments, given that the network usage charges paid by certain power plants in the generation segment have a corresponding revenue receipt by transmission companies within the group. To ensure comparability between 2024 and 2025, the 2024 elimination amounts were revised.

(2) Energy purchased for resale includes: (a) short-term purchases (contracts with a duration of less than 12 months), (b) structural purchases (contracts with a duration of at least 12 months), and (c) results from agents (portions of power plants) that recorded negative settlement at the CCEE during the period. In addition, the effect of intercompany purchases is disregarded, as they are eliminated in accounting consolidation.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Income Tax and Social Contribution:** -R$11,196
million, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ -R$11,398 million
related to deferred tax asset recognition from revised estimates

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ R$203 million
related to deferred tax effects from provision reversals

Regulatory Result: Adjusted EBITDA

In 4Q25, adjusted regulatory EBITDA totaled R$5,745 million, up R$656 million YoY, reflecting:

&nbsp;&nbsp;&nbsp;&nbsp;▪ Increase in generation
revenue along with reduction in energy purchase expenses, excluding the operating results of thermal power plants

&nbsp;&nbsp;&nbsp;&nbsp;▪ Reduction in
PMSO costs and expenses

&nbsp;&nbsp;&nbsp;&nbsp;▪ Increase in transmission
revenue

These effects more than exceeded:

&nbsp;&nbsp;&nbsp;&nbsp;▪ The R$263 million
decline in results from thermal power plants, with the completion of their divestment

&nbsp;&nbsp;&nbsp;&nbsp;▪ The increase
in connectivity costs

&nbsp;&nbsp;&nbsp;&nbsp;▪ The lower contribution
from equity income

Equity income was R$470 million in 4Q25, up R$105 million YoY, primarily driven by the higher contribution from the Belo Monte stake. Worth noting that 4Q25 results do not include income from the stakes in Eletronuclear, as the company was classified as asset held for sale, and in Equatorial Maranhão.

It is worth noting that if one excludes the results from the thermal power plants sold in May and October 2025, EBITDA went up R$919 million, to R$5,724 million in 4Q25 from R$4,805 million in 4Q24.

**3.** **ENERGY TRADING**

AXIA Energia companies sold 31.4 TWh of energy in 4Q25, down 11.8% compared to the 35.6 TWh traded in 4Q24.

The volumes sold include energy from plants under the quota regime, renewed under Law 12,783/2013, as well as from plants operating under the ACL and ACR exploration regimes and consolidated Special Purpose Entities (SPEs): Teles Pires and Baguari HPPs (as of Oct/23), and Retiro Baixo and Santo Antônio HPPs (as of Nov/23).

Contracts signed until 12/31/2025.

The energy balance reflects the SPEs consolidated into AXIA Energia: Santo Antônio HPP (as of 3Q22) and Baguari and Retiro Baixo HPPs (as of 4Q23) in terms of resources, sales, and average prices. Similarly, Teles Pires HPP, an SPE consolidated into AXIA Energia Norte (as of 4Q23), is also included.

&nbsp;&nbsp;&nbsp;&nbsp;1. The energy balance does not include Independent
Power Producers (IPPs) contracts resulting from the Amazonas Distribuidora de-verticalization process, thermal plant availability contracts,
or Assured Capacity Quotas, whether in terms of resources, requirements (sales), or average prices.

&nbsp;&nbsp;&nbsp;&nbsp;2. Own Resources include the decotization plants
(new IPPs) and the New Grants—Sobradinho, Itumbiara, Tucuruí, Curuá-Una, and Mascarenhas de Moraes. For hydroelectric
projects, an estimated GFIS2 was considered, that is, the Assured Capacity adjusted for Internal Loss Factors, Basic Network Loss Factors,
and Availability Factors, as well as adjustments for portfolio-specific characteristics.

&nbsp;&nbsp;&nbsp;&nbsp;3. The revised Assured Capacity values, as outlined
in Ordinance No. 709/GM/MME, of November 30, 2022, have been taken into account.

&nbsp;&nbsp;&nbsp;&nbsp;4. With the gradual phasing out of quota-based generation
legacy contracts (decotization), plants currently operating under the quota regime are gradually granted new concessions under the IPP
regime over a five-year period beginning in 2023. The Assured Capacity values were established in Ordinance GM/MME No. 544/21.

&nbsp;&nbsp;&nbsp;&nbsp;5. Considering the new concession grants from 2023
onward for the Sobradinho, Itumbiara, Tucuruí, Curuá-Una, and Mascarenhas de Moraes plants, whose Assured Capacity values
were established in Ordinance GM/MME No. 544/21.

&nbsp;&nbsp;&nbsp;&nbsp;6. The balances include all energy purchased for
resale: (a) short-term purchases (contracts with a duration of less than 12 months) and (b) structural purchases (contracts with a duration
of at least 12 months). Additionally, the balances include intercompany transactions, impacting both energy purchase and sales lines in
the ACL, in the following amounts: approximately 900 aMW in 2025 and 550 aMW in 2026 and 500 aMW in 2027.

&nbsp;&nbsp;&nbsp;&nbsp;7. Average prices consider taxes in effect as of
the date of this report (February 26, 2026).

&nbsp;&nbsp;&nbsp;&nbsp;8. The figures represent an estimate of uncontracted
energy. The estimated values for 2025, 2026 and 2027 is 81.8%. Worth noting that the average historical GSF from 2019 to 2024 was 82.7%.

&nbsp;&nbsp;&nbsp;&nbsp;9. This excludes the Assured Capacity of Jaguari
HPP (12.7 aMW), whose concession remains under AXIA Energia's interim management.

&nbsp;&nbsp;&nbsp;&nbsp;10. Decotization occurs gradually over a five-year
period beginning in 2023. The Assured Capacity values applied from 2023 onward are those established in Ordinance GM/MME No. 544/21.

Expansion Projects - Transmission

Large Scale Projects

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Projects:** 224<sup>[1]</sup>, including the Itaipu
HVDC System Revitalization project. Throughout 4Q25, the sample was reduced from 230 to 224 projects, due to 38 projects that were energized
and the inclusion of 32 new authorizations issued by the regulator.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Estimated investment:** R$6.09 billion, excluding
the Itaipu HVDC System Revitalization project, as AXIA Energia is responsible solely for its execution, and therefore does not benefit
from associated revenue while being fully reimbursed for the amount disbursed.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Auctions:** Investments of R$7.87 billion, mainly
driven by the following SPEs: Nova Era Janapu, which was part of the sample since 2Q24, while Nova Era Catarina, Nova Era Ceará,
Nova Era Integração and Nova Era Teresina were added in 3Q24<sup>[2]</sup>. The lot acquired in Auction 01/2022, awarded
to AXIA Energia Norte, was concluded in August 2025 — 13 months ahead of schedule.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Additional associated RAP:** R$1.8 billion between
2025-2030.

Small Scale Projects

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Works:** 8,009 small-scale events under implementation
or to be implemented, of which 7,577 were improvements and 432 were reinforcements. Data from ONS Improvement and Reinforcement Plan Management
System (SGPMR).

**5.** **INDEBTEDNESS**

Net debt totaled R$46,484 million in 4Q25, up R$3,908 million sequentially and R$8,814 million YoY.

As a result of a 275 bps increase in the Brazilian basic interest rate (Selic), the Company's total average cost increased to CDI + 0.63% p.a. in 4Q25 from CDI + 0.07% p.a. in 4Q24 while average debt maturity was reduced by 3.6 months in 4Q25 when compared to 4Q24.

**6.** **COMPULSORY LOAN**

AXIA Energia has implemented measures to mitigate risks associated with legal proceedings related to compulsory loans on electricity<sup>[3]</sup>. To address this, the Company has strengthened its legal defense strategy and pursued settlements with discounts and full resolution of lawsuits. As a result of the negotiations:

&nbsp;&nbsp;&nbsp;&nbsp;▪ The inventory of provisions was reduced by
R$2.6 billion YoY and R$663 million sequentially, totaling R$11.1 billion in 4Q25, mainly due to the agreements

&nbsp;&nbsp;&nbsp;&nbsp;▪ Net reversal of R$138 million due to executed
agreements and favorable decisions in the quarter

&nbsp;&nbsp;&nbsp;&nbsp;▪ R$161 million was the amount recorded in
4Q25 under financial expenses related to monetary restatements

&nbsp;&nbsp;&nbsp;&nbsp;▪ With the execution of new agreements in 4Q25,
R$78 million in guarantees previously deposited in court will be released upon approval, bringing the total released since 3Q22 to R$
2.7 billion

Since 3Q22, when negotiations began, the provision inventory related to compulsory loan fell by R$14.8 billion, reaching R$11.1 billion in 4Q25, even considering the accumulated R$3.0 billion monetary restatement in the period. The agreements also enabled the elimination of R$10.9 billion in legal risks considered "off balance", of which R$1.1 billion was classified as possible and R$9.7 billion as remote.

(1) Eliminations: These refer to the portion of transmission system usage charges paid by AXIA Energia's generators to the Company's own transmission companies, which receive them as RAP. For accounting consolidation purposes (Tables 5 and 6), these amounts are eliminated from both transmission revenue and generation usage charges. For management purposes, gross transmission revenue in 4Q25 is R$4,719 million, and including the accounting elimination of -R$264 million, this translates into accounting revenue of R$4,455 million. In the case of generation connection charges costs, for management purposes, the value in 4Q25 is R$1,169 million, and including the accounting elimination of R$264 million, this translates into an accounting cost of R$905 million.

(2) Energy purchased for resale includes: (a) short-term purchases (contracts with a duration of less than 12 months), (b) structural purchases (contracts with a duration of at least 12 months), and (c) results from agents (portions of power plants) that recorded negative settlement at the CCEE during the period. In addition, the effect of intercompany purchases is disregarded, as they are eliminated in accounting consolidation.

(3) The "RHR Hedge Cost" and "Other Operating Costs" lines, related to the generation segment costs, make up the "Other PMSO Costs" line under the accounting view. For a better understanding of the contribution margin by segment, from a management perspective, both lines are allocated in the composition of the contribution margin from generation. In 4Q25, the adjusted regulatory PMSO under the accounting view totaled R$1,761 million, composed of R$52 million in RHR hedge costs and R$13 million in other generation operating costs, both allocated in the margin from generation, and R$1,696 million in other cost and expense components for personnel, materials, services and other. At the same time, in 4Q25, the adjusted IFRS PMSO from an accounting perspective totaled R$1,763 million, comprised of R$52 million in RHR hedge costs and R$13 million in other generation operating costs, both allocated to the margin from generation, and R$1,698 million in other cost and expense components related to personnel, materials, services, and other.

(2) Energy purchased for resale includes: (a) short-term purchases (contracts with a duration of less than 12 months), (b) structural purchases (contracts with a duration of at least 12 months), and (c) results from agents (portions of power plants) that recorded negative settlement at the CCEE during the period. In addition, the effect of intercompany purchases is disregarded, as they are eliminated in the accounting consolidation.

(3) The "RHR Hedge Cost" and "Other Operating Costs" lines, related to generation segment costs, make up the "Other PMSO Costs" line under the accounting view. For a better understanding of the contribution margin by segment, from a management perspective, both lines are allocated in the composition of the contribution margin from generation. In 4Q24, the adjusted regulatory PMSO under the accounting view totaled R$2,093 million, composed of R$39 million in RHR hedge costs and R$10 million in other generation operating costs, both allocated in the margin from generation, and R$2,043 million in other cost and expense components for personnel, materials, services and others. At the same time, in 4Q24, the adjusted IFRS PMSO from an accounting perspective totaled R$2,060 million, comprised of R$39 million in RRH hedging costs and R$10 million in other generation operating costs, both allocated to the margin from generation, and R$2,010 million in other cost and expense components related to personnel, materials, services, and others.

8.2. Generation Segment

Revenue by Contracting Environment

Recurring regulatory revenue was R$7,021 million in 4Q25, in line with adjusted IFRS generation revenue. In both 4Q24 and 3Q25, this difference reflected the accounting treatment of the portion of revenue from Amazonas Energia related to previously unpaid amounts, following a change in the assessment of receivables. Under IFRS, these amounts were recognized as revenue, while under regulatory accounting—where such recognition had already occurred—there was also a reversal of the provision recorded at that time. The difference, which had been recognized in previous comparison periods, had the same nature at that time.

Two effects on energy sales in the regulated market deserve highlight:

&nbsp;&nbsp;&nbsp;&nbsp;▪ R$276 million<sup>[4]</sup>
provision recorded in 4Q25 related to reimbursement to counterparties of availability contracts in the regulated market (ACR) and reserve
energy contracts for wind farm generation shortfalls considering both annual and quadrennial assessments for the period from 2021 to 2025

&nbsp;&nbsp;&nbsp;&nbsp;▪ 95% revenue reduction
from thermal plant energy sales, as 4Q25 reflected only Santa Cruz TPP revenue through October 9, 2025, when the sale closed

(1) Provision due to energy committed under ACR-d and CER contracts, but neither generated nor supplied.

(2) M&A: Includes revenue from assets in which AXIA Energia's stake has changed over the past 12 months.

(3) Energy sales related to the 12th and 13th Existing Energy Auctions (LEN) of the Tucuruí HPP, resulting from the extension of the concession term through the signing of a contract in the Regulated Contracting Environment (ACR), following the renegotiation of hydrological risk for electricity generation, as per ANEEL Ruling No. 1,395, dated May 20, 2019. The revenues refer to the period from July 12, 2024, to August 30, 2024. This event, which affected only 3Q24—with no equivalent effect in the following periods—generated a sold volume of 1,872 MWm, recognized revenue of R$1,327 million, and an average price of R$321/MWh.

(4) Short-term market: the Brazilian electric energy trading chamber (CCEE).

(5) Main effect: recognition of a negative amount of R$26 million in 3Q25, related to adjustments in the value of thermal power plant sale transactions. This effect refers to obligations and rights with maturities extending beyond the completion of the transactions and is treated as a non-recurring adjustment to gross revenue in the period.

(6) The differences between IFRS and regulatory revenues in 3Q25, and 4Q24 refer to energy sold and unpaid for by Amazonas Energia, which was not recognized as revenue under IFRS accounting, but recorded under regulatory accounting, where it was fully provisioned.

<br> Regulatory Margin from Generation

The contribution margin from generation reflects the value added by this segment's results, considering energy trading and directly related costs, and excluding Personnel, Materials, Services, and Other expenses.

The contribution of generation to the results increased to R$3,059 million in 4Q25 from R$2,962 million in 4Q24, despite the sale of thermal power plants and the lower volume of available energy due to the GSF (Generation Scaling Factor), which fell to 67.4% in 4Q25 from 79.9% in 4Q24.

In unit terms, the margin by volume of available energy (energy resource) increased to R$92.05/MWh in 4Q25 from R$84.96/MWh in 4Q24.

It is worth noting that, when excluding the thermal power plant results (Table 19), the unit contribution margin rose to R$91.55/MWh in 4Q25 from R$80/MWh in 4Q24, while energy resources remained practically stable, up to 15,026 aMW from 14,903 aMW, even with a lower GSF, attributable to the 2025 portfolio allocation strategy and protection via hydrological risk renegotiation.

(6) Includes own resources and structural purchases, considering contracts with a supply term longer than 12 months.

The contribution margin of energy traded in the Free Contracting Market (ACL) and settled in the Short Term Market (MCP) increased to R$101/MWh in 4Q25 from R$78/MWh in 4Q24, considering the resources available for allocation in both environments.

The increase in resources available for allocation in the ACL and MCP reflected, from the energy balance requirements side, the release of volumes resulting from the decotization and committed to fulfilling the sales contracts of thermal power plants. This effect more than offset the reduction in total resources for trading, explained by the sale of thermal power plants. From the hydroelectric side, the strategy of allocating own energy throughout 2025 helped to neutralize the reduction in GSF (Generation Scaling Factor) in 4Q25.

The contribution margin increased to R$2,006 million in 4Q25 from R$1,312 million in 4Q24. This increase was explained by energy trading strategy results, with revenue growth despite flat energy purchase spending, more than offsetting the R$152 million increase in connection charges (TUST) during the period.

8.3. Transmission Segment

Regulatory Margin from Transmission

Net transmission revenue comprises gross revenue and its respective deductions and, for management purposes, represents the contribution margin of this segment.

Gross transmission revenue is based on the Allowed Annual Revenue (RAP) and the Adjustment Portion (PA) approved by ANEEL for the current tariff cycle, 2025/2026 (from July 1, 2025, to June 30, 2026). It is worth noting that the PA of the current tariff cycle is a contractual mechanism established by the regulator to compensate for any deficit or surplus between the revenue billed and the RAP approved in the previous cycle.

In addition, gross revenue includes:

&nbsp;&nbsp;&nbsp;&nbsp;▪ taxes and charges
that are not part of the RAP (gross up);

&nbsp;&nbsp;&nbsp;&nbsp;▪ discounts for
unavailability

&nbsp;&nbsp;&nbsp;&nbsp;▪ additional RAP
related to new facilities that entered into operations after the approval

&nbsp;&nbsp;&nbsp;&nbsp;▪ pass-through
items, which are offset in the following cycle through the PA

Accounting eliminations related to transmission system usage charges paid by AXIA Energia's generation companies to the Group's own transmission subsidiaries are not considered. Deductions include taxes (PIS/COFINS, ICMS, and ISS) and sector charges (CDE, PROINFA, TFSEE, R&D, and RGR).

Net regulatory transmission revenue was R$3,924 million in 4Q25, up 3.1% YoY, mainly reflecting the lower PA in the current tariff cycle.

It is worth noting that the RAP variation was primarily explained by:

&nbsp;&nbsp;&nbsp;&nbsp;▪ the repositioning
of RBSE's financial component

&nbsp;&nbsp;&nbsp;&nbsp;▪ the review of
resources linked to the 2023 Periodic Tariff Review (RTP)

&nbsp;&nbsp;&nbsp;&nbsp;▪ the addition
of RAP from reinforcement and improvement projects authorized by the regulator

The variation in PA was primarily explained by the occurrence in 4Q24, without a corresponding impact in 4Q25, of a negative Postponement portion related to the 2023 RTP, according to ANEEL Resolution 3,344/2024, applicable only to the 2024/2025 tariff cycle.

Sequentially, when compared to the R$4,187 million recorded in 3Q25, the R$263 million decrease in the contribution margin was mainly explained by lower collection of items that will be compensated through PA in the following cycle, including:

&nbsp;&nbsp;&nbsp;&nbsp;▪ R$113 million
related to deficit between ONS-calculated collection and approved RAP for the tariff cycle

&nbsp;&nbsp;&nbsp;&nbsp;▪ R$82 million
associated with uncollected fines on connection contracts terminated but unpaid by generators in the quarter

&nbsp;&nbsp;&nbsp;&nbsp;▪ R$44 million
related to the reduction in deficit between ONS-calculated collection and approved RAP for the tariff cycle for a connection dedicated
to Itaipu's exclusive use

Further details and explanations are available in the "Modeling Support - Transmission" spreadsheet, located in the Results Center on the Company's Investor Relations website, including an analysis of the transmission revenue and a breakdown of the Adjustment Portion (PA).

(1) RAP and PA: considers 1/4 of the amounts approved for the tariff cycle in effect during the quarter, and proportional amounts accumulated throughout the year.

(2) Considers (a) PIS/COFINS and (b) CDE/Proinfa. Both are pass-through costs, and AXIA Energia collects these amounts from consumers.

(3) Discount associated with Variable Portion (PV), suspension of Base Payment (PB) due to unavailability, and pending items in Release Terms (TL).

(4) Items for which transmission companies act only as collection agents, and which will be deducted in PA in the following tariff cycle.

This involves differences between approved RAP and ONS billing related to prepayment apportionment,

as the receipt of CDE Fund resources (via CCEE) for amounts not collected due to discounts applied on tariffs.

(5) Other mismatches in relation to the approved RAP for the current tariff cycle, such as (a) mismatch

between Transmission and Distribution Annual Adjustments, (b) complementary AVCs associated with the termination of

Transmission System Usage Agreements (CUST) by generators, etc.

(6) Does not consider the accounting elimination effect of charges paid to the Company's own transmission segment.

Eliminations: transactions that occur between companies of the same group, i.e., AXIA Energia companies.

These refer to transmission system usage charges paid by AXIA Energia generation companies to AXIA Energia transmission companies,

which receive them in the form of RAP. For consolidation purposes, these amounts are eliminated from

transmission revenue and generation usage cost.

(7) Sector Charges includes: RGR, R&D, TFSEE, CDE, and Proinfa.

(1) Energy purchased for resale includes: (a) short-term purchases (contracts with a duration of less than 12 months), (b) structural purchases (contracts with a duration of at least 12 months), and (c) results from agents (portions of power plants) that recorded negative settlement at the CCEE during the period. In addition, the effect of intercompany purchases is disregarded, as they are eliminated in the accounting consolidation.

Energy purchased for resale, charges on the use of electricity grid, fuel for electricity production, and construction costs comprise the generation and transmission margins.

The explanation of the remaining lines, including PMSO (Personnel, Materials, Services, and Other), is provided below.

Positive values in the table above indicate reversal of provision.

\* Primarily Includes impairment and RGR refunds.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Provision for litigation:** provision of R$380
million in 4Q25 compared to a provision of R$486 million in 4Q24. The R$106 million variation was explained by the recording of provisions
in civil, tax, labor, regulatory, environmental, land, and other proceedings, partially offset by the reversal of provisions in compulsory
loan proceedings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Compulsory Loan:
Contributed a net reversal of R$138 million in 4Q25, compared to the net reversal of R$359 million in 4Q24, reflecting agreements signed
and favorable decisions. It is worth noting that, unlike other provisions, the monetary restatement related to the compulsory loan provision
was recognized under financial results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Other events,
contributing to results as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in provision
balances: provision of R$349 million in 4Q25 vs. R$634 million in 4Q24, a positive variation of R$285 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Monetary update:
R$168 million expense in 4Q25 compared to R$210 million in 4Q24

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Share conversion process – Compulsory Loan:** R$
192 million provision in 4Q25, compared to a R$23 million provision in 4Q24. This result reflects the mark-to-market effect on the average
price of the Company's class B preferred shares over the past 12 months, related to amounts recorded in the balance sheet and linked
to those shares. In addition, there is an impact from the increased provision due to the dividends of the period.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Fair value measurement of asset held for sale:** no
recognitions in 4Q25, after a R$137 million provision was recorded in 4Q24, primarily relating to the devaluation of the equity stake
in the SPE Mata de Santa Genebra.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Estimated losses on investments:** reversal of
R$133 million in 4Q25 vs. reversal of R$217 million in 4Q24, an R$84 million variation mainly explained by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ R$153 million:
reversal of impairment in Norte Energia in 4Q24

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ R$122 million:
reversal of equity holdings in SPEs MESA, Sinop and São Manoel

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ R$88 million:
reversal of impairment in AXIA Energia Nordeste in 4Q24

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ R$68 million:
provisions for equity holdings in ISA Energia Brasil in 4Q24

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Expected Credit Losses (ECL) - Consumers and Resellers:** provision
of R$84 million in 4Q25, due to:

![](image_003.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ R$69 million
related to uncollected Transmission System Usage Charges (EUST)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ R$41 million
from monetary update

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Onerous Contracts:** R$200 million reversal in 4Q25 compared
to a R$251 million reversal in 4Q24. The recognition is predominantly explained by the reassessment of the contract with the Jirau HPP.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Impairment:** The R$227 million amount recognized
in 4Q25 resulted from impairment testing of the Casa Nova (R$141 million), Coxilha Negra (-R$340 million), and Ibirapuitã (R$
28 million) wind farms, as detailed in the table below:

8.5. Equity Holdings - IFRS

The main highlights of equity income were as follows:

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Eletronuclear:** No income was recognized in 4Q25 as the asset
was classified as held-for-sale

&nbsp;&nbsp;&nbsp;&nbsp;▪ **ISA Energia**: reduction due to higher financial expenses from
new debt raised for investment execution

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Equatorial Maranhão**: variation resulting from the non-recognition of equity accounting in 4Q25

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Belo Monte Transmissora de Energia S.A.**: reduction
from contractual asset adjustment for lower IPCA in 4Q25 versus 4Q24

![](image_003.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Norte Energia**: increase due to deferred tax asset write-offs
in 4Q24 with no counterpart in 4Q25

(1) To properly assess interest expense on total debt, including hedge results contracted to protect part of the debt, the analysis must consider both line items: "debt charges" and "change in fair value of hedged debt, net of derivative." The first reflects interest on the unhedged portion of debt, while the second reflects not only interest on the hedged portion of debt but also fair value changes of the associated hedging instruments.

(2) These obligations were established by Law 14,182/21 (Privatization of Eletrobras, now AXIA Energia) as a condition for obtaining new concession grants for power generation for an additional 30 years. The charges were calculated based on data published in CNPE Resolution 015/2021, considering (a) the present value of the obligation; (b) the future payment flow; and (c) the payment term.

The main variations this quarter were:

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Financial Income:** went up 21% YoY, to R$1,173
million in 4Q25 from R$971 million in 4Q24, primarily explained by the increase in the average CDI rate during the period, which exceeded
the 13% reduction in average cash balance

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Interest expense on debt and change in fair value of hedge:** resulting,
respectively, from the expenses related to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• R$1,403 million
from debt charges

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• R$685 million
from the change in the fair value of hedged debt, net of derivatives

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In 4Q25, these
lines totaled R$2,088 million compared to R$1,830 million in 4Q24. This 14% increase stemmed primarily from higher Selic rate and new
hedge contracts, partially offset by lower leasing charges after thermal plant sales

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Monetary variations:** R$121 million expense in 4Q25, down
50% from R$242 million in 4Q24. This line is comprised by two main components:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Lawsuit update
for compulsory loans: R$161 million expense in 4Q25 from R$176 million in 4Q24, reflecting the reduction in the provision inventory,
which offset the higher Selic rate

![](image_003.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Other lines:
R$40 million income in 4Q25 compared to a R$66 million expense in 4Q24, mainly explained by a R$52 million decrease in debt monetary
restatement resulting from lower inflation-adjusted debt balances during the period

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Other financial expenses:** R$260 million in 4Q25,
down 15% from the R$306 million in 4Q24. The reduction was mainly explained by the R$34 million judicial deposits write-off in 4Q24,
with no corresponding entry in 4Q25.

8.7. Current and Deferred Taxes - IFRS

In 4Q25, the highlight was the recognition of R$12,362 million in deferred tax assets, comprising:

&nbsp;&nbsp;&nbsp;&nbsp;▪ R$3,512 million
related to deferred tax on tax loss carryforwards and negative tax base

&nbsp;&nbsp;&nbsp;&nbsp;▪ R$9,053 million
related to deferred tax on temporary differences

This event is explained by changes in estimates of future taxable profits. It is important to note that R$2,493 million related to non-operating results remains unrecognized.

<u>Non-recurring effects</u>: -R$12,362 million, including:

&nbsp;&nbsp;&nbsp;&nbsp;▪ -R$12,565 million
related to the deferred tax assets recognized as described above

![](image_003.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;▪ R$203 million
related to deferred tax on provision reversals

(1) The amount of R$12,565 million in 4Q25 refers to the recognition of deferred tax assets on tax loss carryforwards, negative basis and temporary differences, following the revision of future taxable income. In 4Q24, the net constitution of R$1,425 million reflects the constitution of R$1,594 million at AXIA Energia, after studies of the recoverability of negative tax bases and temporary differences, combined with the reversal of R$169 million at AXIA Energia Sul, following the analysis of the recoverability of deferred tax resulting from the sale of TPP Candiota. In 2Q24, two amounts were recognized: R$1,074 million at AXIA Energia, related to tax credits, stemming from accumulated tax loss carryforwards, following a reassessment of taxable income due to the merger with Furnas; and a reversal of R$292.4 million at AXIA Energia Sul, based on a revised expectation regarding the completion of the operations required to utilize the tax credit generated by the sale of TPP Candiota.

(2) In 2Q25, the amount of R$882 million was recognized in connection with the Regulatory Remeasurement, due to changes in the payment schedule of the RBSE financial component for contracts extended under Law 12,783/2013, for 2025-26, 2026-27 and 2027-28 cycle, as approved by ANEEL's Board at its 20th Ordinary Public Meeting on June 10, 2025. In 4Q24, the amount of R$758 million refers to the regulatory remeasurement of AXIA Energia's contractual assets carried out in 3Q24. Although the remeasurement was recognized in that period, the corresponding deferred tax expense was recorded in 4Q24. On that occasion, the expense was reallocated to 3Q24, in line with its recurring nature in fiscal year 2024, consistent with the treatment given to the taxable event and the expenses of the other subsidiaries recognized in 3Q24 .<br>

**9.** **OPERATIONAL PERFORMANCE**
