INTRODUCTION

Rio de Janeiro, August 11, 2021

A Eletrobras (Centrais Elétricas BrasileirasS.A.)[B3: ELET3 and ELET6 – NYSE: EBR e EBR-B – LATIBEX: XELTO and XELTB]

Eletrobras, the largest company in the electric energy sector in Latin America, active in the generation, transmission and commercialization segment, controlling 5 operating subsidiaries and a holding company – Eletropar –, a research center – Cepel, holding 50% of the share capital of Itaipu Binacional and, on June 30, 2021, with direct and indirect interest in 83 Special Purpose Entities, announces, on this date, its results for the period referring to the second quarter of 2021.

2^nd^ QUARTER OF 2021

Eletrobras presented, in the second quarter of 2021 (2Q21), a net profit of R$ 2,530 million, higher than the profit of R$ 469 million obtained in the second quarter of 2020 (2Q20). The 2Q21 profit was positively impacted by transmission results, as a result of the Periodic Tariff Review with effect from July 2020 and by the improvement in generation results, mainly due to the increase in volume and prices practiced in bilateral agreements of ACL (free market) and higher income in the short-term market arising from the settlement at the CCEE due to the increase in the price of the PLD (+ R$517 million), and negatively impacted due to provisions for contingencies of R$ 1,099 million, especially R$ 600 million related to the compulsory loan.

Net Operating Revenue went from R$ 5,337 million in 2Q20 to R$ 7,959 million in 2Q21, a growth of 49%, influenced by the effect on transmission revenue from the tariff review, the higher revenue from settlement with the CCEE, mentioned above. Ebtida IFRS, in the amount of R$ 1,992 million in 2Q20, increased to an amount of R$ 3,222 million in 2Q21, impacted by the aforementioned effect on revenue. Recurring Net Operating Revenue grew by 49%, from R$5,326 million in 2Q20 to R$ 7,943 million in 2Q21. Recurring EBITDA increased by 116%, from R$2,219 million in 2Q20 to R$ 4,794 million in 2Q21.

With the application of Circular Letter CVM/SNC/SEP 04/2020, issued on December 1, 2020, Eletrobras made, since 4Q20, retrospective adjustments in the measurement of its: (i) transmission assets - Existing Basic Systems Network (RBSE), until then classified as financial assets, starting to treat them as contract assets under the terms of CPC 47/IFRS 15 - Revenue from Contracts with Customers; and (ii) change in the remuneration rate of its other transmission assets considering the new criteria established in the guidance issued by CVM. Retrospective adjustments (2Q20) were made to maintain the comparative basis. For more information, see Note 4.4 to the 2Q21 Financial Statements.

•	At the holding (+R$62 million): sale in the CCEE short-term market, of energy originating from energy<br>imports from Uruguay, on demand by the SIN. In the same period of 2020, there was no imported energy sold in the spot market by Eletrobras.
---	---
•	At Chesf (+R$ 43 million): The variation is mainly due to: (i) increase in the average PLD from R$ 75.47/MWh<br>(2Q20) to R$ 229.44/MWh (2Q21) and from the GSF from 92.04% (2Q20) to 99.76% (2Q21), despite the increase in energy sold by about 82 average<br>MW in the supply and supply accounts above, and, therefore, the lower energy surplus in relation to to the same period of 2020.
---	---
•	In Furnas (+R$31 million): (i) The variation is mainly due to the following reasons: (i) an increase of<br>R$83 million arising from the booking of the Santa Cruz Plant in the MCP, which had higher generation in the period 2021, by emergency<br>dispatch; On the other hand, (ii) despite the GSF variation showing an increase of approximately 8% (92% in 2020 and 100% in 2021), there<br>was a greater negative exposure in the period, which together with the increase in the PLD (2020: R$ 75.47 / 2021: R$ 229.44), resulted<br>in an impact of R$ 54 million. .
---	---
•	At CGT Eletrosul (+R$27 million): (i) increase of 204% in the PLD (from R$75 / MWh in 2Q20 to R$230 /<br>MWh in 2Q21), corresponding to a positive variation of R$26 million; (iii) SPE Livramento was responsible for an increase of R$0.21 million<br>in 2Q21; and, (iii) other variations caused by other effects of market accounting.
---	---

Partially offset by:

•	In the subsidiary Amazonas GT (-R$ 17 million): (i) in 2Q20, due to the greater dispatch controlled by<br>the ONS, the UTE Mauá 03 plant had a revenue of approximately R$ 15.5 million, while in 2Q21, we had a greater exposure in the<br>short-term market due to the unavailability of UTE Aparecida due to claims occurred in two Generating Units.

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

| MARKETLETTER **2Q21** |

| --- | | • | In Furnas (+R$ 33 million): (i) annual readjustment of the RAG (approximately 11%) which reflects an increase<br>of R$ 33 million, pursuant to Aneel Ratifying Resolution 2746/2020; (ii) entry of the Jaguari plant (Ex. CPFL) in Jan/21, temporarily<br>operated by Furnas, representing an increase in revenue of R$ 3 million, without comparison in 2020. On the other hand, (iii) the variation<br>in CFURH and, consequently, PIS/COFINS, in the sum of the period, account for the remainder of the difference (R$ -2 million). | | --- | --- |

CONSTRUCTION REVENUE

•	Higher level of investment made in 2Q21, but with no effect on results as it has an equivalent amount<br>in construction expenses.

Itaipu TRANSFER

•

At the Holding (+R$ 87 million): (i) Tariff variation on which the monetary restatement is applied, calculated<br>based on the American Commercial Price and Industrial goods price indices, levied on Itaipu's financial asset, which offset the levied<br>exchange variation on said asset, recognized by interministerial ordinance 04/2018 of the MME and Ministry of Finance that determines<br>the revenue of Itaipu.

ANALYSIS OF VARIATION 2021X2020

•	Revenue from the Power Generation segment grew by 7% in the 1st half of 2021, in line with the same period<br>of the previous year. This growth was mainly influenced by the higher revenue at the CCEE, caused by the increase in pld and the import<br>of energy from Uruguay by the holding, for sale, by order of the ONS, due to the low volume of reservoirs in Brazil, and by the growth<br>in revenue of Operation and Maintenance Revenue, caused by the annual readjustment of the RAG. This revenue growth was partially offset<br>by the reduction in supply revenue at the subsidiary Eletronuclear, especially in 2Q21, as explained above.

•

The costs and expenses of personnel, material, services and others presented, in the 1st half of 2021,<br>a variation of 10.4% compared to the same period of the previous year, mainly reflecting: (i) non-recurring expenses of approximately<br>R$ 80 million due to the dismissal of 285 employees between January and March 2021. Increase of R$54 million in the Eletronuclear Personnel<br>account, impacted by the adjustment of the vacation provision in 2020, reducing the cost and causing a variation of R$42 million in compared<br>periods and higher expenses with social charges in the amount of R$15.5 million; Increase in Eletronuclear's Services bill of R$42 million,<br>mainly explained by: (i) in both periods compared, there were 2 plant shutdowns, however, the scope of work for the shutdowns in 2020<br>was reduced due to the Covid Pandemic -19. Several activities were not performed in that year, being transferred to execution in 2021,<br>which caused a higher expense in the compared periods.

process, as Aneel's Board of Directors had already deliberated, on March 19, 2019, the result of the First Inspection Period of CCC reimbursements to Amazonas Energia, with the company entitled to receive a credit in the order of R$1,592 million (at September 2018 prices), to be offset against the credits to be returned. The net balance of credits assigned by Amazonas Energia, positive in R$ 2.44 billion, refers, in addition to the contract signed with the distributor, with the payment of the amount of R$ 442 million in current credits, upon revenue of the disallowances of the CCC arising from economic and energy efficiency criteria, a right recognized by Law 13,299/2016, in the historical amount of R$ 1,358 million to be paid by the National Treasury. Eletrobras updated the value of economic and energy “inefficiency” by Selic until 06/30/2021.

On June 15, 2021, Aneel approved the result of the inspection and monthly reprocessing of the benefits reimbursed by CCC to Boa Vista Energia, setting the amount to be reimbursed by CCC to the distributor at R$ 103,883,187.32, at prices of February 2020, and establishing that the payment to Eletrobras, holder of the credits, must await the final result (1st and 2nd periods) of the inspections carried out at Amazonas Energia, Ceron, Eletroacre and Boa Vista Energia. As the result was in line with the information contained in Technical Note No. 49/2020-SFF-SFG-SRG/ANEEL, of April 6, 2020, Eletrobras did not need to make new adjustments to the credits assumed by Boa Vista.

Technical Note No. 106/2021-SFF-SFG-SRG/ANEEL, of June 14, 2021, informed the value, still preliminary, of the result of the 2nd inspection period of Ceron. In this technical note, in

addition to the analysis of CCC processing and reimbursements for the 2nd inspection period, the two claims still pending analysis by Aneel were also analyzed, and which Eletrobras understood as likely to be accepted by the Agency: i) Financial costs arising from CCDs, based on two Interministerial Ordinances (652/2014 and 372/2015); and ii) Recognition of guaranteed energy and specific consumption of the Guascor and Rovema contracts, signed before Law 12,111/2009 and Aneel Normative Resolution No. 427/2011.

Aneel partially accepted both claims. Recognized the effects of Interministerial Ordinance No. 652/2014 for CCDs, correction by Selic from the taxable event and accumulated debt balance until Nov/2014, but did not recognize the effects of Interministerial Ordinance No. 372/2015, which increased the term for training of the outstanding balance until Jun/15. Regarding the energy supply contracts signed with Guascor (1998) and Rovema (2006), Aneel recognized the contractual issue on guaranteed energy, but did not accept the claim regarding the recognition of the specific consumption limit defined in the contract. Thus, the technical note contains the total amount to be received by Ceron of R$806,574,733.65, in the April/2021 position, to be reimbursed by the CCC to Eletrobras.

On June 21, 2021, Technical Note No. 111/2021-SFF-SFG-SRG/ANEEL was issued on the 2nd inspection period of Eletroacre. As previously reported, Aneel partially accepted the two claims still pending analysis: i) Financial costs arising from CCDs; and ii) Recognition of guaranteed energy and specific consumption of the contract with Guascor. The total result shown in the technical note is the return of BRL 97,529,535.30, in the position of April/2021, from Eletroacre to the CCC, that is, negative result for the 2nd pe inspection period of the distributor.

Thus, by June 30, 2021, Aneel has completed five inspection processes of the CCC, Amazonas (1st and 2nd periods), Ceron (1st period), Eletroacre (1st period), and Boa Vista (1st period), remaining finalize the inspection processes for the 2nd period of the last three mentioned distributors. The total value of these five inspections closed is R$1,937 million, position of June 2021. Additionally, Aneel released technical notes on the 2nd inspection period of Ceron and Eletroacre, and if the agency's board of directors decides to maintain the amount that contained in the technical notes, the result of the inspection will be R$ 2,656 million to be paid to Eletrobras. Only the 2nd inspection period at Boa Vista still does not have a technical note issued by Aneel with the preliminary result of the inspection.

It is noteworthy that Eletrobras made adjustments in this 2nd ITR in the credits assigned from the distributors and which depend on the inspection by the CCC, in line with the values ​​contained in the technical notes issued by Aneel referring to the 2nd inspection period of Ceron and Eletroacre.

It was established by Aneel's Board of Directors that only after the completion of all eight inspection processes and the ratification of the results, the total net amount of credits should be included in the annual budget of the sectorial fund CDE for payment to Eletrobras. Aneel has not yet defined the payment conditions to Eletrobras for the final result of the inspections. The Agency did not accept Eletrobras' request to include in the CDE budget for the year 2021 the payment of installments of the total net amount of the four CCC inspection processes deliberated by the Agency until December 2020.

Eletrobras expects the inspection processes for the 2nd period of Ceron, Eletroacre and Boa Vista to take place until 3Q21, as well as the definition of payment conditions to Eletrobras.

On June 30, 2020, the National Electric Energy Agency - ANEEL approved the tariff review of the transmission concessions extended under the terms of Law 12,783 / 2013. Consequently, it approved the new Permitted Annual Revenue (“RAP”) of these concessions for the 2020-2021 tariff cycle, which brought the following summarized changes, with an impact in relation to the cash flow projection of RBSE receivables:

•       Retrospective change to the wacc for the years 2018 and 2019;

•       Change in the asset base incorporating the write-offs occurred in the 2013-2018 cycle and the readjustment of the new replacement value of the assets associated with RBSE;

•       Incorporation of the payment of the controversial installment "Ke" that had been under judgment since 2017;

•       3 years' redistribution of the differences between the amount effectively received between 2018 and 2019 and the portions now revised via the adjustment portion updated by IPCA.

In April 2021, ANEEL approved the re-profiling of the financial component of RBSE, of the subsidiaries Furnas, Eletronorte, CGT Eletrosul and Chesf. The decision provides for a reduction in the payment curve of the amounts relating to the periodic review of the RAPs associated with transmission facilities for the 2021/2022 and 2022/2023 cycles and an increase in the payment flow in the cycles after 2023, extending such installments until the end of the year. cycle 2027/2028, preserving, however, the remuneration for the WACC, more details see note 36.1 of 1Q21. The effects of profiling will only impact the Company's Financial Statements in 3Q21.

(ii) provision in 2Q21 of R$209 million in ANEEL CCC Provision due to the adjustment of credits assigned to the Holding by the distributors Ceron, in -R$44.7 million, and Eletroacre, in -R$162.5 million, in resulting from the 2nd inspection period, partially offset by the updating of activated credits (see table 20 of this Report).

2.3       Parent Company Financial Result

In 2Q21, the Financial Result positively impacted the Parent Company's result by R$ 617 million, as well as in 2Q20, with a positive result of R$ 67 million. The result was mainly influenced by: (i) exchange rate fluctuation in the period, given the devaluation of the dollar against the real and the situation of passive exchange exposure. The result of net exchange variation went from a negative amount of R$71 million in 2Q20 to a positive result of R$733 million in 2Q21. On the other hand: (ii) Income from interest, commissions and fees increased from R$372 million in 2Q20 to R$213 million in 2Q21, due to the capitalization of Eletronuclear's debt in July 2020, which affected financial income; and (iii) Income from financial investments went from R$187 million in 2Q20 to R$14 million in 2Q21, mainly due to a reduction in the profitability indexes of the Eletronuclear decommissioning fund.
