INTRODUCTION

Rio de Janeiro, March 13, 2022

**A Eletrobras (Centrais Elétricas Brasileiras S.A.)<br> [B3: ELET3 e ELET6 – NYSE: EBR e EBR-B – LATIBEX: XELTO and XELTB]** 

Eletrobras, the largest company in the electricity sector in Latin America, operating in the generation, transmission and commercialization segment, direct controller of 4 operating subsidiaries and a holding company – Eletropar –, a research center – Cepel and direct and indirect participation in 74 Special Purpose Entities, announces, on this date, its results for the period referring to the third quarter of 2022.

2022 Results

Eletrobras presented, in 2022, a net income of BRL 3,638 million, 36% lower than net income of BRL 5,714 million obtained in 2021.

The result for 2022 was negatively impacted by the accounting of expenses foreseen for the Voluntary Dismissal Plan (PDV), carried out in December 2022, in the amount of R$1,260 million (adherence of 2,494 employees, with 13 months of pay back) and also by the increase of R$4,475 million in provisions for doubtful accounts, which increased from R$1,027 million in 2021 to R$5,022 million in 2022, highlighting the provision of R$3,348 made by the Holding for receivables from Amazonas Energia, which aims to reflect the risk observed due to the maintenance of default on debt acknowledgment instruments (ICD), (for details, see explanatory note 40.1 of the financial statements). The 2022 result was also negatively impacted by the deflation that occurred in the period, which resulted in a reduction of R$1,675 million in transmission revenues, in particular contractual revenue (financial revenue) which are readjusted by IPCA and IGPM, according to the year of competence, considering the effects applicable accounting rules (IFRS).

4th QUARTER 2022

Eletrobras presented, in the fourth quarter of 2022 (4Q22), a net loss of R$479 million, lower than the net profit of R$610 million obtained in the fourth quarter of 2021 (4Q21).

The 4Q22 result was negatively impacted by the accounting of the Voluntary Dismissal Plan, carried out in December 2022, non-recurring event in the amount of R$1,260 million. In addition, the 4Q22 result was also impacted by the constitution of a provision for receivables from Amazonas Energia, in the amount of R$2,528 million, and there was also a decrease in the financial result of R$946 million, in particular, by the increase of R$1,098 million of financial expenses with debt charges, due to the consolidation of SPE Santo Antônio Energia (+R$436 million) as of 3Q22, and the impact of R$888 million in financial expenses (IPCA + charges) of obligations with the CDE (charge of 7.6%) and revitalization projects for the hydrographic basins and the Legal Amazon (charge of 5.67%), as established by Law No. 14,182/2021 (Privacy of Eletrobras), as one of the conditions for obtaining new concession grants for the generation of electricity for another 30 years.

The above negative effects were partially offset by the reversal of losses on investments in SPEs, with emphasis on Saesa, Jirau, Sinop, IE Madeira and São Manoel, in the net amount of 918 million, as well as discounts obtained in compulsory loan court agreements , in the amount of R$563 million.

Net Operating Revenue went from R$10,502 million in 4Q21 to R$9,009 million in 4Q22, a decrease of 14%, influenced by the deflation of the period (fall in the IPCA and IGPM), worsening the transmission revenue in a very relevant way, which which was mitigated, in part, by the tariff revision of the 22/23 cycle of 17 transmission contracts.

Generation revenue grew by R$337 million, overcoming the period's challenge in terms of energy prices, given the better hydrological conditions. Two factors were important for this growth, the first being the consolidation of Saesa (+ R$1,262 million) and the second the Company's effort to sell in advance, to 2022, its available energy, through bilateral contracts, allowing a margin of price significantly higher than the market price, mitigating the low PLD. These gains were partially offset by the reduction in revenues from the sale of energy imported from Uruguay (-R$964 million), in the regulated environment, due to better hydrological conditions.

Ebitda IFRS, in the amount of R$2,043 million in 4Q21, increased to an amount of R$1,420 million in 4Q22, mainly due to the aforementioned provision for PCLD, reduction in Transmission revenue as mentioned above and the increase in PMSO (+R$1,627 million), mainly due to non-recurring POS expenses. Excluding the PDV, personnel grew 4% (+R$136 million), less than the annual readjustment provided for in the Collective Bargaining Agreement – ACT 2022/2023 of 12.13%. Adjusted Ebitda decreased by 10%, from R$4,881 million in 4Q21 to R$4,401 million in 4Q22, influenced by the drop in transmission revenue due to deflation.

**VARIATION ANALYSIS 4Q22 X 4Q21**

**ENERGY SUPPLY TO DISTRIBUTION COMPANIES: Revenue obtained from a customer that is not a final consumer, such as generators, traders and distributors.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In Furnas (+R$951 million): (i) consolidation of SAESA (Santo Antônio Energia), which took place
in 3Q22, with revenues of R$1,229 million referring to Energy resellers, of which ACL= R$533.3 million and ACR = BRL 695.8 million; (ii)
updates of SAESA contracts, which are made annually by the IPCA and represented an increase of R$113.56 million; (iii) readjustment of
prices of the ACR contracts of Furnas by the IPCA of approximately R$26 million, these factors being partially offset by (iii) lower
amount of energy contracted in the ACL (1,924 GWh in 2021 to 1,823 GWh in 2022) , representing a reduction of R$24 million in revenue;
(iv) lower dispatch from the Santa Cruz thermal plant, due to better hydrological conditions, 34 GWh in 4Q22 x 667 GWh in 4Q21, resulting
in lower revenue in the amount of R$218 million.

Partially offset by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· At Eletronorte (-R$103 million): The variation is due to: In the ACL:
(i) the decrease of R$160 million in sales revenue from UHE Tucuruí (4Q21 R$713 million X 4Q22 R$553 million) , which occurred
due to the 24% decrease in Contract Prices (4Q21 R$194.93/MWh X 4Q22 R$148.66/MWh), due to: (a) the large supply of energy, due to the
reservoirs of the hydroelectric plants in historic levels and increased generation of renewable sources encouraged (distributed mini-generation)
and by the timid growth in demand, due to the slow recovery of the economy. In ACR: (ii) mainly due to the R$38 million increase in sales
at UTE Mauá (4Q21 R$306 million X 4Q22 R$344 million), a consequence of the 37% increase in contract prices (4Q21 R$464.4/ MWh
X 4Q22 R$634.1/MWh), the contract had a fixed revenue readjustment in Nov/22, due to the IPCA and the increase of R$9 million in
sales at UTE Aparecida (4Q21 R$93 million X 4Q22 R$102 million), as a result of the 44% increase in contract prices (4Q21 R$
465.56/MWh X 4Q22 R$672.24/MWh), the contract had a fixed revenue readjustment in Nov/22, by the IPCA.

**SUPPLY FOR END CONSUMERS: Revenue obtained from a customer who is a final consumer.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Chesf (+R$54 million): increase in the period by around 51 average MW in consumption by industrial customers
achieved by Law 13,182/2015 in 3Q22.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In Furnas (+R$39 million): (i) consolidation of Saesa (+R$32 million) referring to the billing of ACL
customers (4,446,177 average MW and whose contracts are updated annually (IPCA); (ii). 9% readjustment in the unit prices of Furnas supply
contracts, linked to UHE Itumbiara (Law 13,182), resulting in an increase of R$24 million in the period; (iii) new contracts started
in 2022, representing an increase of R$2 million; and on the other hand, there was (iii) a reduction of R$19 million in ICMS paid due
to the variation in the rate between states and allocation of billing to consumer units, by customers.

Partially offset by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· At Eletronorte (-R$38 million): (i) the R$39 million reduction in Albrás revenues, due to variations
in parameters, defined in the contract, used to calculate the final sale price: aluminum price, US Dollar and Sector Charges. (a) 18%
decline in average aluminum prices (US$2,822.7 4Q21 X US$2,306.78 4Q22); (b) negative variation of 6% in the average dollar conversion
rate (4Q21 R$5.58/US$ X 4Q22 R$5.24/US$); (ii) positive variation of R$1 million due to the increase in the sale price of the other sales
contracts for UHE Tucuruí (4Q21 R$221/MWh X 4Q22 R$241/MWh).

**CCEE**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In the holding company (-R$964 million): improvement of the country's hydrological conditions, significantly
reducing the need to import electricity from the Oriental Republic of Uruguay.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· PLD variation of 53% (4Q21 R$118.70/MWh X 4Q22 R$55.70/MWh), affecting Eletronorte (-R$178 million),
referring to energy from the Tucuruí, Samuel and Curuá-uma hydraulic power plants ; Chesf (-R$103 million) and Furnas (-R$54
million).

**OPERATION AND MAINTENANCE REVENUE - PLANTS RENEWED BY LAW 12.783/2013**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Annual RAG readjustment of around 14%, according to Aneel Ratifying Resolution No. 3,068/2022, in addition
to the increase in CFURH in 4Q22, compared to 4Q21, and consequently the associated taxes, with emphasis on Chesf (R$99 million) and
Furnas (+R$59 million).

**CONSTRUCTION REVENUE**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In Furnas (-R$44 million): (i) with the enactment of Law 14,182/21, the treatment for quota-holding plants
was changed and, as of June 22, there will no longer be accounting of the financial asset generated in revenue of construction.

**ITAIPU TRANSFER**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In Holding (+R$324 million): revenue was impacted by US inflation, which in 4Q21 was 5.17% and in 4Q22
was 14.57%.

**ANALYSIS OF VARIATION 2022X2021**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Revenue from the Power Generation segment increased by 7% in 2022, around R$1,531 million, when compared
to 2021, mainly influenced by (i) the incorporation of Saesa (+R$2.46 billion); and (ii) the 11% increase (+R$456 million) in Plant Operation
and Maintenance revenue, due to the readjustment of the RAG (Annual Generation Revenue), pursuant to Ratifying Resolutions issued by Aneel,
and also variations in the CFURH portion. These effects were partially offset by: (iv) Reduction of 62% (-R$1,931 million) in Revenue
from short-term electricity (CCEE), mainly caused by lower revenue from the resale of energy imported from Uruguay (-R $1,408 million)
and the drop in the average PLD (from BRL 134.71 in 2021 to BRL 55.70 in 2022).

**ANALYSIS OF VARIATION 4Q22 X 4Q21**

**O&M REVENUE**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Chesf (-R$88 million): (i) In 4Q21, there was an adjustment in the amount of R$130.9 million involving
one of the O&M revenue accounts, which caused a distortion in the comparison between the quarters of the years involved. Excluding
this effect, 4Q21 amounts to R$532.2 million, which produces a positive variation of 8.1% in revenue. This positive variation is due
to the publication of Aneel Ratifying Resolution 3,067/2022, which contemplated the tariff readjustment of the 22/23 cycle (of 11.29%),
including the effects of the periodic tariff revision of 10 concession contracts of the Company, which are : 010/2007, 012/2007, 009/2011,
010/2011, 017/2011, 005/2012, 017/2012, 018/2012, 019/2012, 008/2011; (iii) reduction of 28% in the amount PA - portion of adjustment
between periods; and (iv) remeasurement of the contractual asset in Nov/21, which impacted comparisons between periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· At CGT Eletrosul (-R$30 million): (i) reduction of approximately 53% of the O&M RAP related to MP
579/2012, which occurred gradually in 1/5 per cycle during the period 2018/19 to 2022/23, as stipulated by ANEEL in the periodic tariff
review process, REH ANEEL nº 2.716/2020, generating a reduction of R$23.9 million in the analyzed period; (ii) transfer of DIT facilities
and respective revenues to the CELESC distributor; in accordance with REN ANEEL º 916/2021, with a reduction effect of R$11.2 million
in the period.

Partially compensated by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· At Eletronorte (+R$63 million): (i) R$70.6 million increase in O&M revenue from the renewed contract
(058/2001), due to: (a) R$132.8 million increase in billed revenue (4Q22 R$569.7 million x 4Q21 R$436.9 million) due to the 22% readjustment
in the RAP of contract 058/2001 by Ratifying Resolution 3067/2022, effective from July/2022; (b) Reduction of R$62.2 million due to
the increase in amortization (R$239.1 million in 4Q21 x R$301.3 million in 4Q22), due to the 2022 tariff readjustment. (ii) R$
increase $3.3 million in O&M revenue, due to the adjustment made to the CDE revenue (not collected) due to the accrual basis
(difference between the revenue amount between the months of December/2022 and December/2021, as the revenue is received in the month
subsequent to the one in which it is accounted for); (iii) Reduction of R$10.6 million in O&M revenue from non-renewed
contracts, due to: (a) Reduction of R$11.2 million due to the increase in amortization (R$74.0 million in 4Q21 x R$85.2 million in
4Q22) due to the 2022 tariff review - Ratifying Resolution 3067/2022. (b) On the other hand, there was an increase of R$0.6 million
in billed revenue (4Q22 R$159.5 million x 4Q21 R$158.9 million). Despite the readjustment of the RAPs of all contracts having been
relevant due to the IPCA of the cycle of Ratifying Resolution 3,067/2022 (11.73% effective from July/2022), the adjustment portion of
the previous cycle of ETE contracts and PVTE had a negative impact of R$15.6 million on billed revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In Furnas (+R$43 million): (i) readjustment of tariff cycles of 11.73%, based on current regulations (REH
nº. 3067/22), in addition to the entry of new assets; (ii) additionally, in the light of the aforementioned resolution, we highlight
that, in October/21, a difference was recognized in relation to the facilities dedicated to the Transport of Itaipu in the order of 60
million. According to articles 2 and 3 of REH 2.958/21 (formerly REH 2.896/21), the retroactive effects to July/21 were considered in
the revenue, that is, the amounts charged under the bills for the months July, August and September/21, impacting only the 4Q21.

**CONSTRUCTION REVENUE – TRANSMISSION**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Chesf (-R$80 million): investments made (appropriated and allocated) in ongoing transmission projects,
associated with concession contracts: 061/2001, 021/2010, 019/2010, 012/2007, 004/2010, 013 /2010, 020/2010, 018/2012, 010/2007, 008/2011,
007/2010, 008/2005, 018/2009, 014/2008, 010/2011, 019/2012, 009/2011, 017/2012 , 005/2008, 005/2012, 007/2005, 017/2009, 006/2009, 017/2011
and 014/2010, offset by (ii) adequacy of the effects of the annual tariff adjustment in light of the publication of REH 3,067/ 2022, reducing
around R$133 million in the contractual asset balance and impacting construction revenue. This is because, in Nov/22, there was an inconsistency
in the percentage of progress of works associated with 2 REA's of the renewed contract, giving rise to the need to adjust the effects
of the annual tariff readjustment. Thus, although there were more investments in 2022, revenue was lower due to lower performance, since
construction revenue is due to a margin calculated in the measurement spreadsheet and applied to investments made in the period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· At Eletronorte (-R$26 million): (i) Launches of annual adjustments made, in the tariff readjustment process
of transmission contracts in the month of July. However, in the years 2021 and 2022, the accounting audit found differences in the amount
that should have been accounted for as an annual adjustment due to the list of modules considered. These adjustments were released in
4Q22 of both years. Thus, as the reduction in 4Q22 was more relevant than that of 4Q21, the impact on construction revenue was negative.
(reduction of R$40.6 million in 4Q22 x reduction of R$14.2 million in 4Q21); (ii) Increase of R$0.4 million, due to higher construction
revenue (R$65.3 million in 4Q22 x R$64.9 million in 4Q21), with emphasis on: (a) increase of R$11.6 million in revenue from the construction
of contracts 058/2001 (R$7.8 million) and 010/2009 (R$2.6 million); and (b) reduction of R$11.2 million in revenue from contracts 001/2009
(R$8.3 million) and 007/2008 (R$2.9 million); (ii) Increase of R$0.4 million due to higher construction revenue (R$65.3 million in 4Q22
x R$64.9 million in 4Q21) mainly due to: (a) Increase of R$11, 6 million in construction revenue, with emphasis on contracts 058/2001
(R$7.8 million) and 010/2009 (R$2.6 million); (b) Reduction of R$11.2 million in revenue from contracts 001/2009 (R$8.3 million)
and 007/2008 (R$2.9 million).

Partially compensated by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In Furnas (+R$89 million): (i) increase in the value of construction revenue for CT 062-RBNI, which in
4Q22 was R$206.64 million and in 4Q21 totaled R$120.89 million. (ii) In the other contracts, the value in 4Q22 was R$4.48 million and
in 4Q21 it was R$1.29 million, both adjusted to an average construction margin of 1.006%.

**CONTRACTUAL REVENUE – TRANSMISSION**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The reduction is mainly due to lower inflation rates (IPCA) in the period, which ended up offsetting the
effects of the increase in contractual assets between 2021 (BRL 59.5 billion) and 2022 (BRL 61 billion). The variation presented in the
companies was: Furnas (-R$628 million); Chesf (-R$367 million); Eletronorte (-R$270 million); CGT Eletrosul (-R$114 million). This effect
is only due to the application of IFRS rules and is different from regualatory revenue, which had the adjustment according tho (ReH nº
3.067/22), in July 2022.

**VARIATION ANALYSIS 2022X2021**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Revenues from the Transmission segment decreased by 10% (-R$1,675 million) in 2022, compared to the same
period of the previous year, mainly influenced by: (i) reduction of 21% (2,046 million) in Transmission Contractual Revenue (Financial
Revenue), due to changes in the IPCA and IGPM indexes between the periods (IPCA of 5.9% and 2022 and 10.74% in 2021), which are used in
the monetary restatement of the balances of contractual assets and impact the value of the financial income of the Contracts.; (ii) decrease
of 3% (-R$42 million) in construction revenues. These effects were partially offset by: (iii) the 7% increase (+R$408 million) in revenue
from operation and maintenance of transmission lines, due to the entry into operation of new projects and due to the Tariff Review process,
based on in the current regulation (REH nº. 3.067/22), which in its annexes details the readjustments of the RAPs (Permitted Annual
Revenue) of Transmitters. Emphasis on the effect of the reprofiling of the financial component of the RBSE, which reduces the portion
of amortization that reduces revenue and applied the Ke, having a relevant impact on the remeasurement of the contractual asset.

**OTHERS REVENUES**

**VARIATION ANALYSIS 4Q21 X 4Q22**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In Furnas (-R$23 million): (i) reduction in revenue from operation, communication and teleassistance services
provided by FURNAS to Mata de Santa Geneva (R$ -11 million); (ii) Accounting of R$79.5 million in Actuarial Gains in 4Q21 x R$76.6 million
in 4Q22 (causing a variation of R$ -2.9 million) and (iii) Sale of Furnas payroll to Banco Bradesco, for a period of over 5 years, which
took place in 4Q21 (R$ -10.7 million).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In the Holding (-R$20 million): negative variation in revenues from Procel (-R$23 million) and Cigas (R$0
in 4Q21 and a reversal of R$35 million in 4Q22), partially offset by revenue of R$32 million from of permit withdrawals (judicial deposit)
regularized in 4Q22 considering the reconciliation work of judicial deposits.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· At Chesf (+R$21 million): (i) R$14 million increase in revenues from telecommunications services; (ii)
R$5 million increase in revenues from operation and maintenance services; (iii) R$1 million increase in revenue from engineering services.

**VARIATION ANALYSIS 4Q22 X 4Q21**

**ENERGY PURCHASED FOR RESALE**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In the holding company (-R$854 million): improvement of the country's hydrological conditions, significantly
reducing the need to import electricity from the Oriental Republic of Uruguay, accompanying the above-reported decline in CEEE revenue
(-R$964 million).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· At Chesf (-R$51 million): Reduction of around 99 average Mw in electricity purchased for resale in 4Q22,
compared to 4Q21. due to better hydrological conditions in 4Q22.

Partially compensated by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In Furnas (+R$419 million): (i) consolidation of Saesa, with a total addition of R$291 million in 4Q22,
without comparison in 4Q21, highlighting: (a) registration of purchased energy of (R$257, 9 million), due to purchases of electricity
for resale under bilateral contracts, and (b) result of the liquidation of CCEE (R$33.5 million); (ii) Price readjustment of the current
contracts for the purchase of Furnas, representing an expense increase of approximately R$36 million; ; (iii) higher volume of purchases
made in 2022 (1,820 GWh vs 1,331 GWh) of R$133 million due, in part, to the carrying out of energy purchase operations not linked to Furnas'
generation portfolio. These purchase operations, which totaled approximately R$110 million, are directly associated with the sale of
energy in the same amount, and do not aim to offset GSF as with traditional purchases; (iii) R$23 million related to energy purchase operations
carried out in 2021, to mitigate the hydrological risk projected at the time, for the year 2022; (iii) increase in PIS/COFINS items, in
the amount of R$15.6 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· At Eletronorte (+R$94 million): (i) +R$26 million referring to the contractual readjustment of the PIE's
based on the IGP-M, which has a counterpart in revenue, due to being pass-through; (ii) +R$5 million in the purchase of energy in the
ACL to replenish ballast in the Southeast submarket; (iii) +R$64.7 million, due to the adjustment in the SPOT market liquidation estimates
registered lower in the period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· At CGT Eletrosul (+R$26 million): (i) increase of 8.5% in the average acquisition price, according to
contractual rules, due to the impact of inflation (IPCA), raising the cost by R$15.6 million; (ii) an increase of 14 MWm in the quantity
purchased (from 372 MWm in 4Q21 to 386 MWm in 4Q22), causing an increase of R$7.5 million in cost; (iii) increase in energy purchased
through the MCP, impacting a cost increase of R$3.1 million. These effects were partially offset by (iv) the variation in PIS/COFINS credits
between the periods, resulting in a reduction of R$0.8 million in the purchase cost.

**FUEL FOR ELECTRIC POWER PRODUCTION**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· At Eletronorte (+R$553 million): (A) Fuel Costs: (i) R$515.2 million related to the adjustment of
 the extemporaneous credit entry of AmGT's PIS/COFINS calculation in 4Q21, with no counterpart in 4Q22, relating to the years 2015 to
 2020. The adjustment was made on a net basis between calculated credits and liabilities of the same nature, non-recurring entry;
 (ii) R$125.4 million referring to ancillary expenses for natural gas (Ship or Pay for Transport and Margin) given that there was an
 increase due to the readjustment of the price of natural gas for the period, as well as the increase in the volume of natural gas
 which is no longer consumed due to the -17.12% reduction in natural gas consumption at the UTEs. Thus, the natural gas that was no
 longer consumed for the production of electricity generated an overpayment obligation of Ship or Pay. We emphasize that this expense
 is not affected by the ICMS reduction, given that it is not characterized as a circulation of goods, but as a contractual financial
 obligation. On the other hand, reduction
of: (iii) R$91 million referring to expenses incurred with the purchase of Fuel for the production of electricity (Natural Gas) in
4Q22, which were lower than expenses in 4Q21 by -16.03% mainly due to the reduction of -24.22% in energy generation at the UTE that
consume natural gas imposed by the ONS as a result of the increase in the reservoirs of the Hydroelectric Power Plants –
UHE of the Submarket of the North Region, causing the dispatches of the UHE of the North Subsystem to be prioritized in comparison
with thermal plants that have inflexibility in their contracts and use fuel in their operation. We also highlight that in 4Q22 the
reduction of ICMS in the total cost of natural gas was also perceived in compliance with State Decree No. based on the IPCA variation
in the last twelve months) showed an increase of only 0.93% in the average price of natural gas, given the reducing effect on the
price as a result of the ICMS exemption. (iv) R$39 million referring to the reversal of ICMS on sales of energy produced by UTE
Mauá 3, due to the consumption of natural gas. The reversal occurs because the sale is outside the state of AM and is
exempt from ICMS; (B) Recovery of expenses - Subsidy received: (i) revenue from the CCC in 4Q22, which had an increase of 25.94% when
compared to 4Q21, due to the readjustment of the price of natural gas for the period, in addition, in 2021 the reimbursement for the
month of November of natural gas was only effected in the month of January 2022.

Partially compensated by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· In Furnas (+R$277 million): (i) lower dispatch from the Santa Cruz plant, of 667 GMh in 4Q21 and 43 GWh
in 4Q22. This dispatch of 43 occurred due to the combined cycle tests and not due to the need to dispatch given that we are in a hydrologically
favorable period.

**NETWORK USE CHARGES**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Readjustment of network usage charges, according to Ratifying Resolution 3066-ANEEL of 06/12/2022 of 15%.

The Fuel account increased by 10% year-over-year, from R$1,890 million in 2021 to R$2,086 million in 2022, mainly due to the adjustment to the extemporaneous credit entry of the PIS/COFINS calculation of Amazonas Energia, which occurred in 4Q21, and ancillary natural gas expenses (Transport Ship or Pay and Margin), due to the effect of the natural gas price readjustment. These effects were partially offset by the generation difference between the periods at UTE Santa Cruz (generation dispatches to the Santa Cruz plant in 2022 amounted to 659 GWh and in the same period of 2021 were 1,745 GWh) and the ICMS reversal of R$124.1 million on sales of energy produced by UTE Mauá 3, due to the consumption of natural gas. The reversal occurs because the sale is outside the state of AM and is exempt from ICMS.

Charges on the use of the electricity grid increased by 21% (R$470 million) in 2022, compared to the same period of the previous year, mainly influenced by the readjustment of the TUST, according to Ratifying Resolution 3,066-ANEEL of 06/12 /2022 of 15%.

book-entry credits (2nd phase), in 4Q22, was R$24.3 billion against R$25.8 billion in 3Q22, a reduction, therefore, of R$1.5 billion,
influenced by the discounts mentioned above, for the payments of agreements that have already had their respective judicial
homologation and the final and unappealable decision, in the total amount of R$737 million, as well as for the increase in monetary
restatement, which was R$1,620 million (as will be explained in the financial result line), in the year 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The provision for Guarantees presented a reversal of R$214 million in 4Q22 due to the change in the methodology
for calculating the provision.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Estimated Losses on Investments showed a reversal of R$918 million in 4Q22, compared to a reversal of
R$91 million in 4Q21, mainly explained by: (i) constitution in Teles Pires of R$468 million (vs the fact that that the gain from the transfer
of the Dardanelos plant will be accounted for upon completion of the operation); and (ii) constitution of a provision of R$68 million
in LT Mata de Santa Geneva. On the other hand, there were reversals in: Companhia Energética Sinop S.A. – R$215 million in
SINOP, R$309 million in Jirau, R$218 million in Interligação Elétrica do Madeira S.A. - IE Madeira.

**VARIATION ANALYSIS 2022X2021**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The Operating Provisions account showed a 52% reduction, which is mainly explained by the variation in
the provision for litigation account, which went from R$13,081 million in 2022 to R$1,858 million in 2021. The Provision for Litigation
was impacted, mainly due to the records related to the compulsory loan, which amounted to R$133 million in 2022 and R$10,897 million in
2021 (due to the review of legal theses and precedents that took place in 3Q21). The reduction in the operating provision for the compulsory
loan was mainly influenced by discounts of R$563 million obtained in court agreements that were signed in 4Q22.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· On the other hand, there was an increase of R$2,709 million in provisions for doubtful accounts of financing
and loans, which increased from R$639 million in 2021 to R$3,348 million in 2022, with emphasis on the provision for loan receivable balances
with to Amazonas Energia (See Note 10 of the Explanatory Notes). There was also constitution of PECLD on consumers and resellers, in the
year ended December 31, 2022, in the amount of R$1,674 million, which is mainly due to the provision of 100% of the Debt Confession Instruments
of Amazonas Energia entered into with Eletronorte . (See note 09 of the Explanatory Notes).

**FINANCIAL RESULT:**

**VARIATION ANALYSIS 4Q22X4Q21** 

In 4Q22, the financial result presented a negative variation, having presented a negative result of R$732 million in 4Q21 and negative R$1,683 million in 4Q22. The main variations were:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Debt Charges, from -R$443 million in 4Q21 to -R$1,542 million in 4Q22, with emphasis on the consolidation
of Saesa, where there was a record of -R$436 million. Of this amount, around R$296 million is monetary restatement and debt interest restated
by the IPCA and around R$137 million is debentures, also restated by the IPCA. In addition, 3 new loan contracts were raised, in Furnas,
in 2Q22, with an impact of R$93 million more on the 4Q22 result. Consolidated accounts were also impacted by the increase in
interest on loans indexed to the CDI, which increased from 13.65 in 4Q22 to 9.15 in 4Q21;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Monetary restatement expenses of the provision for compulsory loan lawsuits (2nd phase – book-entry
credits) of R$284 million in 4Q22, although there was no relevant variation in this expense, since the increase in the selic rate has
already started to as of 4Q21.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Financial Expenses of IPCA + Charges on the outstanding balance of obligations with the CDE (charge of
7.6%) of R$746 million and obligations with the revitalization projects of the hydrographic basins and the Legal Amazon (charge of 5 .67%),
of R$143 million in 4Q22, with no counterpart in 4Q21. These obligations were established by Law 14,182/21 (Eletrobras Privatization),
as one of the conditions for obtaining new concession grants for electricity generation, for another 30 years. Charges were calculated
based on data published in Resolution CNPE 015/2021: (i) present value of the obligation; (ii) the future flow of payments; and (iii)
the payment term.

Partially compensated by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The net exchange variation, which went from a negative net exchange variation of R$125 million in 4Q21
to a positive net exchange variation of R$215 million in 4Q22, mainly due to the debt exposure in dollar and dollar variation in the respective
periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· At Eletronorte, a positive net result associated with derivatives in the amount of R$41 million, in 4Q21,
against a positive net result of R$220 million in 4Q22, due to the variation of the LE - London Metal Exchange in the period. The contract
with Albras provides for a price for the sale of energy plus the payment of a premium, which varies according to the price of aluminum
on the LME, quoted in dollars.

**VARIATION ANALYSIS 2022X2021**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The Net Financial Result went from a net expense of R$1,442 million in 2021 to a net expense of R$4,374
million in 2022, representing an increase of R$2,932 million. This variation is mainly due to: (i) the increase in debt charges, caused
by the consolidation of SAESA, by the raising of new loan agreements that occurred during the year 2022; (ii) expenses with CDE Financial
Charges and Revitalization Projects - Law 14,182/2021, which total R$1,505 million; and (iii) losses on derivatives, which went from a
net income of R$726 million in 2021 to a net expense of R$356 million in 2022, influenced by the variation in the price of aluminum on
the London Metal Exchange – LME, quoted in dollars, which is used as a reference for payment of the premium provided for in the
contract with Albras; (iv) net monetary variations, which went from a net expense of R$35 million to a net expense of R$1,098 million
referring to monetary restatement, especially by Selic, of the provision for compulsory loan lawsuits, which went from an expense from
R$699 million in 2021 to R$1,621 million in 2022, given the variation in the update index between periods.

¹ Eletrobras sold its entire equity interest in CEEE-T to CPFL de Energia Cone Sul Ltda, in April 2022, see note 2.3.

² The residual values of the new concessions were written off against the result for the period due to the irrecoverability determined by the CNPE, for further details see note 1.1.5.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The variation was mainly due to (i) expense arising from the write-off of judicial deposits due to reconciliation
adjustments, in the amount of -R$507 million, partially offset by (ii) write-off of liabilities of R$97 million related to compulsory
loan credits not converted into shares; (iii) R$21.6 million referring to the gain from the sale of the investment in the sale of CEEE-G
shares, as part of the payment of the compulsory loan agreement; and (iv) entry of + R$266 million in write-off of CCC pass-through liabilities,
pursuant to article 206, paragraph 5, I, of the Civil Code.

As provided for in Law nº 14,182/2021, the capitalization of Eletrobras was conditioned to the corporate restructuring to maintain, directly or indirectly, the companies Eletronuclear and Itaipu Binacional, through the transfer of control to ENBpar. The effect on the result, as well as the comparison, were disclosed in 2Q22 in accordance with accounting pronouncement CPC 31/IFRS 5, to present the transactions of the segments mentioned above separately from the continuing operations. Thus, after the capitalization, Eletrobras' shareholding in the total capital of Eletronuclear increased from 99.95% to 67.95%, but Eletrobras does not hold the majority of common shares and no longer has control. In this sense, since 2Q22, Eletronuclear ceased to be a controlled company and became an affiliated company.

Note: As of 2019, the Company began to consider, in its adjusted EBITDA, the RBSE revenue from the extended concessions in light of Law 12,783/2013, in order to maintain a protocol similar to the debenture covenants issued in 2019. In addition, considering the privatization of the distributors was completed in April 2019, and these operations are no longer part of its core business, the company treated as non-adjusted the relevant effects of financial income, expenses, reversals of PL and provisions for prospective PCLD (CPC 48) of loans contracted with them before or as a result of the privatization process, although revenues and eventual provisions arising from loans contracted may continue to affect the company's accounting result until their complete exhaustion. However, they were treated as adjusted PCLD of outstanding effective debt of distributors, as well as their debts related to energy supply, with the exception, therefore, of prospective PCLD provisions (CPC 48) for energy supply.

Due to the atypical scenario and potentially unpredictable characteristics, it is not possible to accurately predict the scenarios that may materialize in the coming months in the company's operations.

\*On the balance of the 2030 and 2025 Bonuses, there is an accounting effect on the deferral of expenses with the repurchase of the 2021 bonus due to the operation carried out in February.
