Note 1. - Nature of the business

Atlantica Sustainable Infrastructure plc (“Atlantica” or the “Company”) is a sustainable infrastructure company with a majority of its business in renewable energy assets. Atlantica currently owns, manages and invests in renewable energy, storage, efficient natural gas and heat, electric transmission lines and water assets focused on North America (the United States, Canada and Mexico), South America (Peru, Chile, Colombia and Uruguay) and EMEA (Spain, Italy, Algeria and South Africa).

Atlantica’s shares trade on the NASDAQ Global Select Market under the symbol “AY”.

In March 2023, the Company completed the process of transitioning O&M services for the assets in Spain where Abengoa was still the supplier to an Atlantica’ subsidiary (Note 5). After this transfer, the Company performs the O&M services with its own personnel for assets representing approximately 72% of the consolidated revenue in 2022. Abengoa currently provides O&M services for assets representing less than 5% of the consolidated revenue of the Company for the year ended December 31, 2022.

The following three assets that the Company had under construction during 2022, finished construction and reached COD in the first quarter of 2023:

- Albisu, a 10 MW PV asset wholly owned by the Company. Albisu is located in the city of Salto (Uruguay). The asset has a 15-year PPA with Montevideo Refrescos, S.R.L, a subsidiary of Coca-Cola Femsa., S.A.B. de C.V. The PPA is denominated in local currency with a maximum and minimum price in U.S. dollars and is adjusted monthly based on a formula referring to U.S. Producer Price Index (PPI), Uruguay’s Consumer Price Index (CPI) and the applicable UYU/U.S. dollar exchange rate.

- La Tolua and Tierra Linda, two wholly owned solar PV assets in Colombia with a combined capacity of 30 MW. Each plant has a 10-year PPA in local currency indexed to local inflation with Coenersa, the largest independent electricity wholesaler in Colombia.

During the year 2022, the Company completed the following investments:

- On January 17, 2022, the Company closed the acquisition of Chile TL4, a 63-mile transmission line and 2 substations in Chile for a total equity investment of $38.4 million (Note 5). The Company expects to expand the transmission line in 2024, which would represent an additional investment of approximately $8 million. The asset has fully contracted revenues in U.S. dollars, with inflation escalation and a 50-year remaining contract life. The off-takers are several mini-hydro plants that receive contracted or regulated payments.

- On April 4, 2022, the Company closed the acquisition of Italy PV 4, a 3.6 MW solar portfolio in Italy for a total equity investment of $3.7 million (Note 5). The asset has regulated revenues under a feed in tariff until 2031.

- On September 2, 2022, the Company completed its third investment through its Chilean renewable energy platform in a 73 MW solar PV plant, Chile PV 3, located in Chile, for $7.7 million corresponding to a 35% of equity interest (Note 5). The Company expects to install batteries with a capacity of approximately 100 MWh in 2024. Total investment including batteries is expected to be in the range of $15 million to $25 million depending on the capital structure. Part of the asset’s revenue is currently based on capacity payments. Adding storage would increase the portion of capacity payments.

- On November 16, 2022, the Company closed the acquisition of a 49% interest, with joint control, in an 80 MW portfolio of solar PV projects in Chile, Chile PMGD, which is currently under construction. Atlantica´s economic rights are expected to be approximately 70%. Total investment in equity and preferred equity is expected to be approximately $30 million and Commercial Operation Date (“COD”) is expected to be progressive in 2024. Revenue for these assets is regulated under the Small Distributed Generation Means Regulation Regime (“PMGD”) for projects with a capacity equal or lower than 9MW, which allows to sell electricity through a stabilized price.

(*) Commercial Operation Date.

In October 2023, Chile PV 2, where the Company owns a 35% equity interest, did not make its debt service payment mainly due to the low electricity prices in Chile, which represents an event of default. The Company and its partner are in conversations with the banks regarding a potential waiver. In addition, Chile PV 1, where the Company owns a 35% equity interest, was not able to maintain the minimum required cash in its debt service reserve account during the third quarter of 2023 due to low electricity prices, which represents an event of default as of September 30, 2023. As a result, although the Company does not expect an acceleration of the debt to be declared by the credit entities, Chile PV 1 did not have an unconditional right to defer the settlement of the debt for at least twelve months and the project debt, which amounts to $49 million as of September 30, 2023 (Note 15), was classified as current in these Consolidated Condensed Interim Financial Statements in accordance with International Accounting Standards 1 (“IAS 1”), “Presentation of Financial Statements”.

Note 2. - Basis of preparation

The accompanying Consolidated Condensed Interim Financial Statements represent the consolidated results of the Company and its subsidiaries.

19

The Company’s annual consolidated financial statements as of December 31, 2022, were approved by the Board of Directors on February 28, 2023.

These Consolidated Condensed Interim Financial Statements are presented in accordance with International Accounting Standards (“IAS”) 34, “Interim Financial Reporting”. In accordance with IAS 34, interim financial information is prepared solely in order to update the most recent annual consolidated financial statements prepared by the Company, placing emphasis on new activities, occurrences and circumstances that have taken place during the nine-month period ended September 30, 2023, and not duplicating the information previously published in the annual consolidated financial statements for the year ended December 31, 2022. Therefore, the Consolidated Condensed Interim Financial Statements do not include all the information that would be required in a complete set of consolidated financial statements prepared in accordance with the IFRS-IASB (“International Financial Reporting Standards-International Accounting Standards Board”). In view of the above, for an adequate understanding of the information, these Consolidated Condensed Interim Financial Statements must be read together with Atlantica’s consolidated financial statements for the year ended December 31, 2022 included in the 2022 20-F.

In determining the information to be disclosed in the notes to the Consolidated Condensed Interim Financial Statements, Atlantica, in accordance with IAS 34, has taken into account its materiality in relation to the Consolidated Condensed Interim Financial Statements.

The Consolidated Condensed Interim Financial Statements are presented in U.S. dollars, which is the parent company’s functional and presentation currency. Amounts included in these Consolidated Condensed Interim Financial Statements are all expressed in thousands of U.S. dollars, unless otherwise indicated.

These Consolidated Condensed Interim Financial Statements were approved by the Board of Directors of the Company on November 7, 2023.

Application of new accounting standards

a) Standards, interpretations and amendments effective from January 1, 2023, under IFRS-IASB, applied by the Company in the preparation of these Consolidated Condensed Interim Financial Statements:

The applications of these amendments have not had any impact on these Consolidated Condensed Interim Financial Statements.

In addition, the IASB published in May 2023 an amendment to IAS 12, “Income taxes”, to clarify the application of this standard arising from tax legislation enacted or substantively enacted in each country to implement the Pillar Two model rules in which it provides:

- a temporary exception to the accounting for deferred taxes in connection with the implementation of Pillar Two.

- qualitative and quantitative disclosures to enable users to understand the entities’ exposure to taxes that may arise from the Pillar Two model rules and/or the entity’s progress in its implementation.

The Company is currently working on analyzing the implications arising from this new regulation applicable for accounting periods commencing on or after December 31, 2023.

b) Standards, interpretations and amendments published by the IASB that will be effective for periods beginning on or after January 1, 2024:

The Company does not anticipate any significant impact on the Consolidated Condensed Interim Financial Statements derived from the application of the new standards and amendments that will be effective for annual periods beginning on or after January 1, 2024, although it is currently still in the process of evaluating such application.

The Company has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

Use of estimates

Some of the accounting policies applied require the application of significant judgment by management to select the appropriate assumptions to determine these estimates. These assumptions and estimates are based on the Company´s historical experience, advice from experienced consultants, forecasts and other circumstances and expectations as of the close of the financial period. The assessment is considered in relation to the global economic situation of the industries and regions where the Company operates, taking into account future development of its businesses. By their nature, these judgments are subject to an inherent degree of uncertainty; therefore, actual results could materially differ from the estimates and assumptions used. In such cases, the carrying values of assets and liabilities are adjusted.

The most critical accounting policies, which require significant management estimates and judgment are as follows:

20

Estimates:

- Impairment of contracted concessional, PP&E and other intangible assets.

- Recoverability of deferred tax assets.

- Fair value of derivative financial instruments

- Fair value of identifiable assets and liabilities arising from a business combination

Judgement:

- Assessment of assets agreements.

- Assessment of control.

As of the date of preparation of these Consolidated Condensed Interim Financial Statements, no relevant changes in estimates made are anticipated and, therefore, no significant changes in the value of assets and liabilities recognized at September 30, 2023, are expected.

Although these estimates and assumptions are being made using all available facts and circumstances, it is possible that future events may require management to amend such estimates and assumptions in future periods. Changes in accounting estimates are recognized prospectively, in accordance with IAS 8, in the consolidated income statement of the period in which the change occurs.

Note 3. - Financial risk management

Atlantica’s activities are exposed to various financial risks: market risk (including currency risk and interest rate risk), credit risk and liquidity risk. Risk is managed by the Company’s Risk Management and Finance Departments, which are responsible for identifying and evaluating financial risks, quantifying them by project, region and company, in accordance with mandatory internal management rules. The internal management rules provide written policies for the management of overall risk, as well as for specific areas. The internal management policies of the Company also define the use of hedging instruments and derivatives and the investment of excess cash.

These Consolidated Condensed Interim Financial Statements do not include all financial risk management information and disclosures required for annual financial statements and should be read together with the information included in Note 3 to Atlantica’s annual consolidated financial statements as of December 31, 2022 included in the 2022 20-F.

Note 4. - Financial information by segment

Atlantica’s segment structure reflects how management currently makes financial decisions and allocates resources. Its operating and reportable segments are based on the following geographies where the contracted concessional assets are located: North America, South America and EMEA. In addition, based on the type of business, as of September 30, 2023, the Company had the following business sectors: Renewable energy, Efficient natural gas and Heat, Transmission lines and Water.

Atlantica’s Chief Operating Decision Maker (CODM), which is the CEO, assesses the performance and assignment of resources according to the identified operating segments. The CODM considers the revenue as a measure of the business activity and the Adjusted EBITDA as a measure of the performance of each segment. Adjusted EBITDA is calculated as profit/(loss) for the period attributable to the parent company, after adding back loss/(profit) attributable to non-controlling interests, income tax expense, financial expense (net), depreciation, amortization and impairment charges of entities included in the these Consolidated Condensed Interim Financial Statements and depreciation and amortization, financial expense and income tax expense of unconsolidated affiliates (pro rata of Atlantica’s equity ownership).

In order to assess performance of the business, the CODM receives reports of each reportable segment using revenue and Adjusted EBITDA. Net interest expense evolution is assessed on a consolidated basis. Financial expense and amortization are not taken into consideration by the CODM for the allocation of resources.

In the nine-month period ended September 30, 2023, Atlantica had three customers with revenues representing more than 10% of total revenue, in the renewable energy business sector. In the nine-month period ended September 30, 2022, Atlantica had two customers with revenues representing more than 10% of total revenue, both in the renewable energy business sector.

Note 5. – Business combinations

For the nine-month period ended September 30, 2023

On March 1, 2023, the Company completed the process of transitioning the O&M services for the assets in Spain where Abengoa was still the supplier to an Atlantica’ subsidiary. This acquisition has been accounted for in these Consolidated Condensed Interim Financial Statements in accordance with IFRS 3, Business Combinations. The O&M services are included within the Renewable energy sector and the EMEA geography.

The fair value of assets and liabilities consolidated at the effective acquisition date is shown in the following table:

	Business combinations for the nine-month period ended September 30, 2023
Property, plant and equipment under IAS 16		1,565
Intangible assets under IAS 38		5,645
Inventories		1,646
Other current and non-current liabilities		(6,653	)
Total net assets acquired at fair value		2,203
Asset acquisition – purchase price		(2,203	)
Net result of business combinations		-

The purchase price equals the fair value of the net assets acquired.

The allocation of the purchase price is provisional as of September 30, 2023, and amounts indicated above may be adjusted during the measurement period to reflect new information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the amounts recognized as of September 30, 2023. The measurement period will not exceed one year from the acquisition date.

The amount of revenue contributed by the acquisitions during the nine-month period ended September 30, 2023 to the Consolidated Condensed Interim Financial Statements of the Company is nil, and the amount of loss after tax is $0.4 million. Had the acquisitions been consolidated from January 1, 2023, the consolidated statement of comprehensive income would not have included additional revenue and profit after tax of $1.0 million.

For the year ended December 31, 2022

On January 17, 2022, the Company closed the acquisition of Chile TL4, a 63-mile transmission line and 2 substations in Chile for a total equity investment of $38.4 million. Atlantica has control over Chile TL4 under IFRS 10, Consolidated Financial Statements. The acquisition of Chile TL4 had been accounted for in these Consolidated Condensed Interim Financial Statements in accordance with IFRS 3, Business Combinations. Chile TL4 is included within the Transmission Lines sector and the South America geography.

On April 4, 2022, the Company closed the acquisition of Italy PV 4, a 3.6 MW solar portfolio in Italy for a total equity investment of $3.7 million. Atlantica has control over Italy PV 4 under IFRS 10, Consolidated Financial Statements. The acquisition of Italy PV 4 had been accounted for in these Consolidated Condensed Interim Financial Statements in accordance with IFRS 3, Business Combinations. Italy PV 4 is included within the Renewable energy sector and the EMEA geography.

On September 2, 2022, the Company closed the acquisition of Chile PV 3, a 73 MW solar PV plant through its renewable energy platform in Chile for a total equity investment of $7.7 million. Atlantica has control over Chile PV 3 under IFRS 10, Consolidated Financial Statements. The acquisition of Chile PV 3 had been accounted for in these Consolidated Condensed Interim Financial Statements in accordance with IFRS 3, Business Combinations, showing 65% of non-controlling interests. Chile PV 3 is included within the Renewable energy sector and the South America geography.

26

The fair value of assets and liabilities consolidated at the effective acquisition date is shown in aggregate on the basis that they are individually not significant in the following table:

	Business combinations for the year ended December 31, 2022
Property, plant and equipment under IAS 16		55,135
Rights of use under IFRS 16 (lessee) or intangible assets under IAS 38		26,794
Cash and cash equivalents		1,057
Other current assets		8,283
Non-current Project debt		(1,301	)
Current Project debt		(148	)

Non-controlling interests		(14,300	)
Total net assets acquired at fair value		49,667
Asset acquisition – purchase price		(49,667	)
Net result of business combinations		-

The purchase price equaled the fair value of the net assets acquired.

The amount of revenue contributed by the acquisitions performed during 2022 to the Consolidated Financial Statements of the Company for the year 2022 was $6.2 million, and the amount of profit after tax was $1.7 million. Had the acquisitions been consolidated from January 1, 2022, the consolidated statement of comprehensive income would have included additional revenue of $4.8 million and additional profit after tax of $1.7 million.

In January, April and September 2023, the provisional period for the purchase price allocation of Chile TL 4, Italy PV 4 and Chile PV 3, respectively, closed, and did not result in significant adjustments to the initial amounts recognized.

Note 6. - Contracted concessional, PP&E and other intangible assets

The Company has assets recorded as contracted concessional assets in accordance with IFRIC 12, property plant and equipment in accordance with IAS 16 and right of use assets under IFRS 16 or intangible assets under IAS 38.

No losses from impairment of contracted concessional, PP&E and other intangible assets, excluding the change in the provision for expected credit losses under IFRS 9, Financial instruments, were recorded during the nine-month period ended September 30, 2023. During the nine-month period ended September 30, 2022, an impairment loss of $41 million was recorded in Solana, due to the continued delays in the works and replacements that the Company was carrying out in its storage system and their impact on production in 2022, as well as an increase in the discount rate.
 

The impairment provision based on the expected credit losses on contracted concessional financial assets decreased by $1 million in the nine-month period ended September 30, 2023 (increase of $27 million in the nine-month period ended September 30, 2022, primarily in ACT).

None of the entities referred to above is a listed company.

2007 Vento II, LLC, is the holding company of a 596 MW portfolio of wind assets (“Vento II”) in the U.S., 49% owned by Atlantica since June 16, 2021, and accounted for under the equity method in these Consolidated Condensed Interim Financial Statements.

Windlectric Inc., the project entity, is 100% owned by Amherst Island Partnership, itself 30% owned by Atlantica Yield Energy Solutions Canada Inc. (“AYES Canada”) and therefore accounted for under the equity method in these Consolidated Condensed Interim Financial Statements.

Myah Bahr Honaine, S.P.A., the project entity, is 51% owned by Geida Tlemcen, S.L., which is accounted for using the equity method in these Consolidated Condensed Interim Financial Statements. Geida Tlemcen, S.L. is 50% owned by Atlantica.

Pemcorp SAPI de CV, Monterrey´s project entity, is 100% owned by Arroyo Netherlands II B.V., which is accounted for under the equity method in these Consolidated Condensed Interim Financial Statements. Arroyo Netherlands II B.V. is 30% owned by Atlantica.

28

Akuo Atlantica PMGD Holding S.P.A.(“Akuo”) is the holding company of an 80 MW portfolio of solar PV assets in Chile, which is currently under construction, 49% owned by Atlantica, with joint control since November 2022 and accounted for under the equity method in these Consolidated Condensed Interim Financial Statements.

The Colombian portfolio of renewable energy entities includes the following entities: Atlantica – HIC Renovables S.A.S., SJ Renovables Sun 1 S.A.S. E.S, AC Renovables Sol 1 S.A.S. E.S, SJ Renovables Wind 1 S.A.S. E., PA Renovables Sol 1 S.A.S. E.S and Atlantica Hidro Colombia S.A.S. On March 1, 2023, Atlantica sold part of its equity interest in these entities to a partner, which now holds a 50% equity interest. Atlantica and the partner hold 50% of the shares each and have joint control over these entities in accordance with IFRS 11, Joint arrangements. As a result, the subsidiaries, which were previously fully consolidated showing 30% of non-controlling interest, are now recorded as an investment in joint ventures under the equity method in these Consolidated Condensed Interim Financial Statements in accordance with IAS 28, Investments in associates and joint ventures. Carrying amount of the non-controlling interests in these entities were derecognized at the date control was lost by Atlantica. Further to the sale of part of its equity interest, Atlantica recorded a gain of $4.6 million as Other operating income in the nine-month period ended September 30, 2023 (Note 20).

The decrease in investments carried under the equity method as of September 30, 2023, is primarily due to the distributions made by Amherst Island Partnership to AYES Canada for the period for $11.1 million related to the investment in Windlectric Inc. A significant portion of the distributions received from Amherst are distributed by the Company to its partner in this project (Note 13). The decrease in the investment in Vento II is primarily due to the distributions received from this asset by the Company for $11.0 million, partially offset by the share of profit in Vento II for the nine-month period ended September 30, 2023 for $5.3 million.

Note 8. - Financial assets

The detail of Non-current and Current financial assets as of September 30, 2023, and December 31, 2022, is as follows:

	Balance as of September 30, 2023		Balance as of December 31, 2022

Other receivable accounts at amortized cost		754		1,477
Total current financial assets		173,532		195,893

Investment in Ten West Link is a 12.5% interest in a 114-mile transmission line in the U.S., currently under construction.

Note 9. - Derivative financial instruments

The breakdowns of the fair value amount of the derivative financial instruments as of September 30, 2023, and December 31, 2022, are as follows:

	Balance as of September 30, 2023				Balance as of December 31, 2022
	($ in thousands)
	Assets		Liabilities		Assets		Liabilities
Interest rate cash flow hedge		109,938		5,523		94,192		12,159
Foreign exchange derivatives instruments		3,610		-		3,189		-
Notes conversion option (Note 14)		-		931		-		4,688
Total		113,548		6,454		97,381		16,847

29

The derivatives are primarily interest rate cash flow hedges. All are classified as non-current assets or non-current liabilities, as they hedge long-term financing agreements.

The net amount of the fair value of interest rate derivatives designated as cash flow hedges transferred to the consolidated condensed income statement is a profit of $18.0 million for the nine-month period ended September 30, 2023 (loss of $31.5 million for the nine-month period ended September 30, 2022).

The after-tax results accumulated in equity in connection with derivatives designated as cash flow hedges as of September 30, 2023, and December 31, 2022, amount to a profit of $357.5 million and $345.6 million, respectively.

Additionally, the Company has currency options with leading international financial institutions, which guarantee minimum Euro-U.S. dollar exchange rates. The strategy of the Company is to hedge the exchange rate for the net distributions from its European assets after deducting euro-denominated interest payments and euro-denominated general and administrative expenses. Through currency options, the strategy of the Company is to hedge 100% of its euro-denominated net exposure for the next 12 months and 75% of its euro denominated net exposure for the following 12 months, on a rolling basis. Change in fair value of these foreign exchange derivatives instruments are directly recorded in the consolidated income statement.

Finally, the conversion option of the Green Exchangeable Notes issued in July 2020 (Note 14) is recorded as a derivative with a fair value (liability) of $0.9 million as of September 30, 2023 ($4.7 million as of December 31, 2022).

Note 10. - Fair value of financial instruments

Financial instruments measured at fair value are classified based on the nature of the inputs used for the calculation of fair value:

- Level 1: Inputs are quoted prices in active markets for identical assets or liabilities.

- Level 2: Fair value is measured based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices).

- Level 3: Fair value is measured based on unobservable inputs for the asset or liability.

As of September 30, 2023, all the financial instruments measured at fair value correspond to derivatives and have been classified as Level 2, except for the investments held in Ten West Link, which has been classified as Level 3.

Note 11. - Related parties

The related parties of the Company are primarily Algonquin Power & Utilities Corp. (“Algonquin”) and its subsidiaries, non-controlling interests (Note 13), entities accounted for under the equity method (Note 7), as well as the Directors and the Senior Management of the Company.

Note 12. - Trade and other receivables

Trade and other receivables as of September 30, 2023, and December 31, 2022, consist of the following:

	Balance as of September 30,		Balance as of December 31,

Other accounts receivable		4,703		17,390

The increase in trade receivables is primarily due to collections pending from the Spanish state-owner regulator, Comision Nacional de los Mercados y de la Competencia or “CNMC” in the solar assets of the Company in Spain and from Pemex in ACT.

During the year 2022, in the assets in Spain, the Company collected revenue in line with the parameters corresponding to the regulation in place at the beginning of the year 2022, as the new parameters, reflecting lower revenue, became final on December 14, 2022. As a result, as of December 31, 2022, trade receivables in the assets in Spain were lower than usual. In the nine-month period ended September 30, 2023, collections at these assets in Spain were regularized.

As of September 30, 2023, and December 31, 2022, the fair value of trade and other receivables accounts does not differ significantly from its carrying amount.

In the nine-month period ended September 30, 2023, the Company issued 103,928 new shares (228,560 new shares in the nine-month period ended September 30, 2022) to its employees to settle a portion of these plans.

During the nine-month period ended September 30, 2022, the Company sold 3,423,593 shares at an average market price of $33.57 pursuant to its distribution agreement, representing net proceeds of $114 million.

Note 15. - Project debt

This note shows the project debt linked to the assets included in Note 6 of these Consolidated Condensed Interim Financial Statements.

Project debt is generally used to finance contracted assets, exclusively using as guarantee the assets and cash flows of the company or group of companies carrying out the activities financed. In addition, the cash of the Company´s projects include funds held to satisfy the customary requirements of certain non-recourse debt agreements and other restricted cash for an amount of $209 million as of September 30, 2023 ($208 million as of December 31, 2022).

Total Project debt		4,412,064		4,553,052

The Company refinanced the Solaben 2&3 assets in March 2023, entering into two green senior euro-denominated loan agreements for the two assets with a syndicate of banks for a total amount of €198.0 million. The new project debt replaced the previous project loans for a similar amount and maturity was extended from December 2030 to June 2037.

Chile PV 1, where the Company owns a 35% equity interest, was not able to maintain the minimum required cash in its debt service reserve account during the third quarter of 2023 due to low electricity prices, which represents an event of default as of September 30, 2023. As a result, although the Company does not expect an acceleration of the debt to be declared by the credit entities, Chile PV 1 did not have an unconditional right to defer the settlement of the debt for at least twelve months and the project debt, which amounts to $49 million as of September 30, 2023, was classified as current in these Consolidated Condensed Interim Financial Statements in accordance with International Accounting Standards 1 (“IAS 1”), “Presentation of Financial Statements”.

The repayment schedule for project debt in accordance with the financing arrangements as of September 30, 2023, is as follows and is consistent with the projected cash flows of the related projects:

The amount recorded in Grants as a liability is progressively recorded as other income over the useful life of the asset.

36

The remaining balance of the “Grants” account corresponds to loans with interest rates below market rates for Solana and Mojave for a total amount of $280 million as of September 30, 2023 ($299 million as of December 31, 2022). Loans with the Federal Financing Bank guaranteed by the Department of Energy for these projects bear interest at a rate below market rates for these types of projects and terms. The difference between proceeds received from these loans and its fair value, is initially recorded as “Grants” in the consolidated statement of financial position, and subsequently recorded progressively in “Other operating income”.

Total amount of income for these two types of grants for Solana and Mojave is $43.8 million and $43.9 million for the nine-month periods ended September 30, 2023 and 2022, respectively (Note 20).

The “Accruals on Spanish market prices differences” corresponds to the non-current portion of the payables related to the high market prices in Spain at which the solar assets in Spain invoiced electricity up to September 30, 2023, as a result of a negative adjustment to the regulated revenues for the deviation from the estimated market prices used by the Administration in Spain, which is expected to be compensated over the remaining regulatory life of the solar assets of the Company.

Note 17. - Trade payables and other current liabilities

Trade payables and other current liabilities as of September 30, 2023, and December 31, 2022, are as follows:

Nominal values of trade payables and other current liabilities are considered to be approximately equal to fair values and the effect of discounting them is not significant.

Note 18. - Income Tax

The effective tax rate for the periods presented has been established based on management’s best estimates, taking into account the tax treatment of permanent differences and tax credits.

For the nine-month period ended September 30, 2023, income tax amounted to a $11,587 thousand expense with respect to a profit before income tax of $60,483 thousand. In the nine-month period ended September 30, 2022, income tax amounted to a $12,975 thousand expense with respect to a profit before income tax of $14,780 thousand. The effective tax rate differs from the nominal tax rate mainly due to permanent tax differences in some jurisdictions.

Note 19. - Financial expense, net

Financial income and expense

The following table sets forth financial income and expenses for the nine-month periods ended September 30, 2023 and 2022:

	For the nine-month period ended September 30,

Total		(243,083	)		(243,208	)

Gains and losses from interest rate derivatives designated as cash flow hedges primarily correspond to transfers from equity to financial expense when the hedged item impacts the consolidated income statement. The decrease of losses and increase of gains in the nine-month period ended September 30, 2023 compared to the nine-month period ended September 30, 2022, is due to an increase in the spot interest rates in 2023 compared to 2022, which implies lower interest payments on the derivatives instruments contracted.

Net exchange differences

Net exchange differences primarily correspond to realized and unrealized exchange gains and losses on transactions in foreign currencies as part of the normal course of business of the Company.

Other financial income and expenses

The following table sets out Other financial income and expenses for the nine-month periods ended September 30, 2023, and 2022:

Other financial losses primarily include guarantees and letters of credit, other bank fees and non-monetary interest expenses for updating the present value of provisions and other long-term liabilities reflecting passage of time.

Note 20. - Other operating income and expenses

The table below shows the detail of Other operating income and expenses for the nine-month periods ended September 30, 2023, and 2022:

The decrease in other operating expenses for the nine-month period ended September 30, 2023 is primarily due to:

-  the internalization of the O&M services in the solar assets in Spain during 2022 and 2023. These services are now provided by employees of Atlantica, whose cost is classified within the line “Employee benefit expense” of the profit and loss statement; and

-  to the lower cost of supplies due to lower price of electricity in the solar assets in Spain in 2023.

Note 21. - Earnings per share

Basic earnings per share have been calculated by dividing the profit/(loss) attributable to equity holders of the Company by the average number of outstanding shares.

Average number of outstanding diluted shares for the nine-month period ended September 30, 2023 have been calculated considering the potential issuance of 3,347,305 shares (3,347,305 shares for the nine-month period ended September 30, 2022) on the settlement of the Green Exchangeable Notes (Note 14) and the potential issuance of 219,762 shares (224,269 shares for the nine-month period ended September 30, 2022) under the long-term incentive plans granted to employees. It also included the potential issuance of 596,681 shares to Algonquin for the nine-month period ended September 30, 2022 under the agreement signed on August 3, 2021, according to which Algonquin has the option, on a quarterly basis, to subscribe such number of shares to maintain its percentage in Atlantica in relation to the use of the ATM program (Note 13).

(*) The potential ordinary shares related to the Green Exchangeable Notes and the long-term incentive plans granted to employees have not been considered in the calculation of diluted earnings per share for the nine-month period ended September 30, 2023, as they have an antidilutive effect. For the nine-month period ended September 30, 2022, the potential ordinary shares related to the long-term incentive plans granted to employees and the ATM program have not been considered in the calculation of diluted earnings per share as they have an antidilutive effect.

Note 22. - Subsequent events

On October 16th, 2023, Chile PV 2 did not make its project debt service mainly due to the low electricity prices in Chile, which represents an event of default under its financing arrangement. The carrying amount of the debt of $21.5 million shall not be reclassified yet as current as of September 30, 2023, in accordance with IAS 1, Presentation of Financial Statements. The Company and its partner are currently in conversations with the banks to obtain a potential waiver.

On November 7, 2023, the Board of Directors of the Company approved a dividend of $0.445 per share, which is expected to be paid on December 15, 2023.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read together with, and is qualified in its entirety by reference to, our Consolidated Condensed Interim Financial Statements and our Annual Consolidated Financial Statements prepared in accordance with IFRS as issued by the IASB and other disclosures including the disclosures under “Part II, Item 1.A.—Risk Factors” of this quarterly report and “Part I, Item 3.D.—Risk Factors” in our Annual Report. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs, which are based on assumptions we believe to be reasonable. Our actual results could differ materially from those discussed in such forward-looking statements. The results shown here are not necessarily indicative of the results expected in any future period. Please see our Annual Report for additional discussion of various factors affecting our results of operations.

Overview

We are a sustainable infrastructure company with a majority of our business in renewable energy assets. Our purpose is to support the transition towards a more sustainable world by investing in and managing sustainable infrastructure, while creating long-term value for our investors and the rest of our stakeholders. In 2022, our renewable sector represented 75% of our revenue, with solar energy representing 64%. We complement our renewable assets portfolio with storage, efficient natural gas and transmission infrastructure assets, as enablers of the transition towards a clean energy mix. We also hold water assets, a relevant sector for sustainable development.

As of the date of this quarterly report, we own or have an interest in a portfolio of assets and new projects under development, diversified both in terms of business sector and geographic footprint. Our portfolio consists of 44 operating assets with 2,161 MW of aggregate renewable energy installed generation capacity (of which approximately 73% is solar), 343 MW of efficient natural gas-fired power generation capacity, 55 MWt of district heating capacity, 1,229 miles of electric transmission lines and 17.5 M ft3 per day of water desalination.

We currently own and manage operating facilities and projects under development in North America (United States, Canada and Mexico), South America (Peru, Chile, Colombia and Uruguay) and EMEA (Spain, Italy, Algeria and South Africa). Our assets generally have contracted or regulated revenue. As of September 30, 2023, our assets had a weighted average remaining contract life of approximately 13 years¹.

We intend to grow our business through the development and construction of our project pipeline including expansion and repowering opportunities, as well as greenfield developments, third-party acquisitions and the optimization of our existing portfolio. We currently have a pipeline of assets under development of approximately 2.1 GW of renewable energy and 6.0 GWh of storage. Approximately 44% of the projects are PV, 42% storage 13% wind and 1% other projects, while 37% are expected to reach ready-to-build (“RTB”) in 2023-2024 or are in an advanced development stage and 63% are in early stage. Also, 23% are expansion or repowering opportunities of existing assets and 77% greenfield developments.

Our objective is to pay a consistent and growing cash dividend to shareholders that is sustainable on a long-term basis. We expect to distribute a significant percentage of our cash available for distribution as cash dividends and we will seek to increase such cash dividends over time through organic growth, investments in new assets and acquisitions.

Recent Investments

• In January 2022, we closed the acquisition of Chile TL 4, a 63-mile transmission line, and two substations in Chile for a total equity investment of $38.4 million. We expect to expand the transmission line in 2024, which would represent an additional investment of approximately $8 million. The asset has fully contracted revenues in U.S. dollars, with annual inflation adjustments and a 50-year remaining contract life. The off-takers are several mini-hydro plants that receive contracted or regulated payments.

¹ Calculated as weighted average years remaining as of September 30, 2023 based on CAFD estimates for the 2023-2026 period.

40

• In April 2022, we closed the acquisition of Italy PV 4, a 3.6 MW solar portfolio in Italy, for a total equity investment of $3.7 million. The asset has regulated revenues under a feed in tariff until 2031.

• In September 2022, we closed the acquisition of Chile PV 3, a 73 MW solar PV plant, through our renewable energy platform in Chile. The equity investment corresponding to our 35% equity interest was $7.7 million, and we expect to install batteries with a capacity of approximately 100 MWh in 2024. Total investment including batteries is expected to be in the range of $15 million to $25 million depending on the capital structure. Part of the asset’s revenue is currently based on capacity payments. Adding storage would increase the portion of capacity payments.

(3) Corresponds to the expected investment by Atlantica

(4) Atlantica owns 50% of the shares in Honda 1 and Honda 2

(5) The contract is in the process of being transferred to Conelsur

• In September 2022, we agreed our first investment in a standalone battery storage project of 100 MWh (4 hours) capacity located inside Coso, our geothermal asset in California. Our investment is expected to be in the range of $40 million to $50 million. This project is at an advanced stage, we are preparing to start construction and we have closed a contract with Tesla for the procurement of the batteries. COD is expected in early 2025.

In October 2023, we entered into two 15-year tolling agreements (PPAs) with an investment grade utility for Coso Batteries 1 and Coso Batteries 2. Coso Batteries 2 is a standalone battery storage project with 80 MWh (4 hours) capacity also located inside Coso, and which is currently under advanced development. Our investment is expected to be initially in the range of $35 to $45 million. COD is expected in 2025. We have also entered into an agreement with Tesla for the procurement of batteries. Under each of the tolling agreements recently signed, Coso Batteries 1 and 2 will receive fixed monthly payments adjusted by the financial settlement of CAISO’s Day-Ahead market. In addition, we expect to obtain revenue from ancillary services in each of the assets.

• In November 2022, we closed the acquisition of a 49% interest, with joint control, in an 80 MW portfolio of solar PV projects in Chile which is currently under construction (Chile PMGD). Our economic rights are expected to be approximately 70%. Total investment in equity and preferred equity is expected to be approximately $30 million and COD is expected to be progressive in 2024. Revenue for these assets is regulated under the Small Distributed Generation Means Regulation Regime (“PMGD”) for projects with a capacity equal or lower than 9 MW which allows to sell electricity at a stabilized price.

41

• In July 2022 we closed a 12-year transmission service agreement denominated in U.S. dollars that will allow us to build a substation and a 2.4-mile transmission line connected to our ATN transmission line serving a new mine in Peru (ATN Expansion 3). The substation is expected to enter in operation in 2024 and the investment is expected to be approximately $12 million.

• In July 2023, as part of the New Transmission Plan Update in Peru, the Ministry of Energy and Mines published the Ministerial Resolution that enables to start construction of our ATS Expansion 1 project, consisting in the reinforcement of two existing substation with new equipment. The expansion will be part of our existing concession contract, a 30-year contract with a fixed-price tariff base denominated in U.S. dollars adjusted annually in accordance with the U.S. Finished Goods Less Foods and Energy Index as published by the U.S. Department of Labor. Given that the concession ends in 2044, we will be compensated with a one-time payment for the remaining 9 years of concession. The expansion is expected to enter in operation in 2025 and the investment is expected to be approximately $30 million.

• In May 2022, we agreed to develop and construct Honda 1 and 2, two PV assets in Colombia with a combined capacity of 20 MW. Each plant has a 6-year PPA with Enel Colombia commencing at COD, which is expected in the fourth quarter of 2023. Our investment is expected to be $5.5 million for each plant.

In addition, the three assets that we had under construction during 2022 entered into operation in the first quarter of 2023:

• Albisu, the 10 MW PV asset wholly owned by us reached COD in January 2023. Albisu is located in Uruguay and has a 15-year PPA with Montevideo Refrescos, S.R.L., a subsidiary of Coca-Cola Femsa, S.A.B. de C.V. The PPA is denominated in local currency with a maximum and minimum price in U.S. dollars and is adjusted monthly based on a formula referring to the U.S. Producer Price Index (PPI), Uruguay’s Consumer Price Index (CPI) and the applicable UYU/U.S. dollar exchange rate.

• La Tolua and Tierra Linda are two wholly owned solar PV assets in Colombia with a combined capacity of 30 MW which reached COD in the first quarter of 2023. Each plant has a 10-year PPA which commenced in the first quarter of 2023, in local currency with Coenersa, the largest independent electricity wholesaler in Colombia.

Recent Developments

• Operation and Maintenance. In March 2023, we completed the process of transitioning the O&M services for our assets in Spain through the acquisition of the business of an Abengoa subsidiary which was still providing those services to some of our assets. After this transfer, we performed the O&M services with our own personnel for assets representing approximately 72% of our consolidated revenue for the year ended December 31, 2022, and the number of our employees increased to approximately 1,350. Abengoa currently provides O&M services for assets representing less than 5% of our consolidated revenue for the year ended December 31, 2022.

In addition, in July 2023 we internalized the O&M services for ATN, which were previously performed by Omega Peru Operacion y Mantenimiento S.A. (“Omega Peru”). Additionally, the O&M contract for ATS with Omega Peru, which could be terminated every five years was modified and can now be terminated every three years (or every two years under certain circumstances) and the contract for ATN2, which was a long-term contract expiring in 2027, was also modified and can now also be terminated every three years (or every two years under certain circumstances).

• Strategic Review. On February 21, 2023, Atlantica’s board of directors commenced a process to explore and evaluate potential strategic alternatives that may be available to Atlantica to maximize shareholder value. The Company believes it has attractive growth and other opportunities in front of it and is committed to ensuring it is best positioned to take advantage of those opportunities. The decision has the support of the Company’s largest shareholder, Algonquin. Atlantica expects to continue executing on its existing plans while the review of strategic alternatives is ongoing, including its current growth plan. As of the date of this report, the strategic review is ongoing. There is no assurance that any specific transaction will be consummated or other strategic change will be implemented as a result of this strategic review. See “Cautionary Statements Regarding Forward-Looking Statements” and “Part I, Item 3.D.—Risk Factors” in our Annual Report.

• Regulation in Spain. On December 28, 2022, the proposed parameters for the year 2023 were published in draft form and on June 30, 2023, the final parameters were published, including a revised assumption for electricity prices for the years 2023, 2024 and 2025, resulting in a higher Remuneration on Investment than that included in the draft published in December 2022. The parameters are as follows:

	Useful Life	Remuneration on Investment 2023 (euros/MW)		Remuneration on Operation 2023 (euros/GWh)		Adjustment Rate		Maximum Hours		Minimum Hours		Operating Threshold

• In June 2023 we executed an EPC heat exchanger performance bond at Kaxu for approximately $11 million, as we believe that the conditions were met. The EPC supplier has informed us that they intend to start an arbitration process. The cash received in connection with such bond has been recorded as a deferred income and is expected to be used for repairs at the asset.

• Our partner in Monterrey initiated a process to sell its 70% stake in the asset. Such process is well advanced and, as part of it, we intend to sell our interest as well under the same terms. The net proceeds to Atlantica are expected to be in the range of $46 to $53 million, after tax. The transaction is subject to certain conditions precedent and final transaction closing. We cannot guarantee that the transaction will finally close.

• Dividend. On November 7, 2023, our board of directors approved a dividend of $0.445 per share. The dividend is expected to be paid on December 15, 2023, to shareholders of record as of November 30, 2023.

Potential Implications of Abengoa Developments

Prior to the transfer of the O&M services from Abengoa to us previously mentioned, Abengoa. S.A. and its subsidiary in Spain who were performing the O&M services at some of our plants, filed for insolvency proceedings. There may be unanticipated consequences of such insolvency filings and potential liquidation process. See “Part I, Item 3.D.—Risk Factors—Risks Related to Our Relationship with Algonquin and Abengoa” in our Annual Report.

Factors Affecting the Comparability of Our Results of Operations

Investments

The results of operations of Chile TL4, Italy PV 4 and Chile PV 3 have been fully consolidated since January 2022, April 2022 and September 2022, respectively and the results of Albisu, Tierra Linda and La Tolua have been fully consolidated since these assets entered into operation in the first quarter of 2023. These investments represented additional revenue of $7.0 million and additional Adjusted EBITDA of $5.3 million for the nine-month period ended September 30, 2023.

Impairment

In the nine-month period ended September 30, 2022, we recorded an impairment loss of $41.2 million in Solana with no corresponding amount in 2023.

In addition, IFRS 9 requires impairment provisions to be based on expected credit losses on financial assets rather than on actual credit losses, which affects the concessional assets accounted for as financial assets. For the nine-month periods ended September 30, 2023 and 2022 we recorded an increase in the expected credit loss impairment provision of $1.1 million and $27.2 million, respectively, each of which is reflected in the line item “Depreciation, amortization, and impairment charges” and was primarily related to ACT.

Electricity market prices

Total revenue in Spain decreased by $15.8 million in the nine-month period ended September 30, 2023 compared to the same period of the previous year. In addition to regulated revenue, our solar assets in Spain receive revenue from the sale of electricity at market prices. The average electricity market price captured by our assets was approximately €69.9 per MWh in the first nine months of 2023 compared to approximately €149.5 per MWh in the first nine months of 2022. Revenue from the sale of electricity at current market prices represented $73.0 million in the first nine months of 2023, compared to $136.9 million in the first nine months of 2022. Regulated revenues are revised periodically to reflect, among other things, the difference between expected and actual market prices if the difference is higher than a pre-defined threshold and as a result, we record a provision. We increased our provision by $3.9 million in the nine-month period ended September 30,2023, with no cash impact on the current period, compared to an increase of $28.2 million in the same period of the previous year.

On May 12, 2022, remuneration parameters in Spain for the year 2022 were published and became final on December 14, 2022, with a decrease in regulated revenue. In addition, on December 28, 2022, the proposed parameters for the year 2023 were published in draft form and on June 30, 2023, the final parameters were published, including a revised assumption on electricity prices for the years 2023, 2024 and 2025, resulting in a higher Remuneration on Investment with respect to that included in the draft parameters published in December 2022. Revenue from the sale of electricity at market prices net of the incremental market price provision was $69.1 million for the nine-month period ended September 30, 2023, compared to $108.6 million for the nine-month period ended September 30, 2022.

In 2022 we collected revenue from our assets in line with the parameters corresponding to the regulation in place at the beginning of the year 2022, as the new parameters became final on December 14, 2022, while revenue for the year ended December 31, 2022, was recorded in accordance with the new parameters. Collections were regularized in the first quarter of 2023.

Exchange rates

We refer to “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Significant Trends Affecting Results of Operations—Exchange rates” below.

44

Significant Trends Affecting Results of Operations

Investments

If the acquisitions recently closed and new assets recently built perform as expected, we expect these assets to positively impact our results of operations in 2023 and upcoming years.

Solar, wind and geothermal resources

The availability of solar, wind and geothermal resources affects the financial performance of our renewable assets, which may impact our overall financial performance. Due to the variable nature of solar, wind and geothermal resources, we cannot predict future availabilities or potential variances from expected performance levels from quarter to quarter. Based on the extent to which the solar, wind and geothermal resources are not available at expected levels, this could have a negative impact on our results of operations.

Capital markets conditions

The capital markets in general are subject to volatility that is unrelated to the operating performance of companies. Our growth strategy depends on our ability to close investments and acquisitions, which often requires access to debt and equity financing to complete these acquisitions. Volatility in capital markets may affect our ability to access this capital through debt or equity financings.

Exchange rates

Our presentation currency and the functional currency of most of our subsidiaries is the U.S. dollar, as most of their revenue and expenses are denominated or linked to U.S. dollars. All our companies located in North America, with the exception of Calgary, with revenue in Canadian dollars, and most of our companies in South America have their revenue and financing contracts signed in or indexed totally or partially to U.S. dollars. Our solar power plants in Europe have their revenue and expenses denominated in euros, Kaxu, our solar plant in South Africa, has its revenue and expenses denominated in South African rand, La Sierpe, La Tolua and Tierra Linda our solar plants in Colombia have their revenue and expenses denominated in Colombian pesos and Albisu, our solar plant in Uruguay, has its revenue denominated in Uruguayan pesos, with a maximum and a minimum price in U.S. dollars.

Project financing is typically denominated in the same currency as that of the contracted revenue agreement, which limits our exposure to foreign exchange risk. In addition, we maintain part of our corporate general and administrative expenses and part of our corporate debt in euros which creates a natural hedge for the distributions we receive from our assets in Europe. To further mitigate this exposure, our strategy is to hedge cash distributions from our assets in Europe. We hedge the exchange rate for the net distributions in euros (after deducting interest payments and general and administrative expenses in euros). Through currency options, we have hedged 100% of our euro-denominated net exposure for the next 12 months and 75% of our euro-denominated net exposure for the following 12 months. We expect to continue with this hedging strategy on a rolling basis.

Although we hedge cash-flows in euros, fluctuations in the value of the euro in relation to the U.S. dollar may affect our operating results. For example, revenue in euro-denominated companies could decrease when translated to U.S. dollars at the average foreign exchange rate solely due to a decrease in the average foreign exchange rate, in spite of revenue in the original currency being stable. Fluctuations in the value of South African rand and Colombian peso with respect to the U.S. dollar may also affect our operating results.

In our discussion of operating results, when foreign currency exchange differences are material we usually include foreign currency exchange impacts in our revenue by providing constant currency revenue growth. The constant currency presentation is not a measure recognized under IFRS and excludes the impact of fluctuations in foreign currency exchange rates. We have not included constant currency information in this discussion given that the effect of foreign currency exchange rates is not significant for the nine-month period ended September 30, 2023.

Impacts associated with fluctuations in foreign currency are discussed in more detail under “Item 3—Quantitative and Qualitative Disclosure about Market Risk—Foreign exchange risk”.

45

Interest rates

We incur significant indebtedness at the corporate and asset level. The interest rate risk arises mainly from indebtedness at variable interest rates. To mitigate interest rate risk, we primarily use long-term interest rate swaps and interest rate options which, in exchange for a fee, offer protection against a rise in interest rates. As of September 30, 2023, approximately 93% of our consolidated debt has fixed rates or is hedged. As of that same date, 92% of our project debt and approximately 96% of our corporate debt either has fixed interest rates or has been hedged with swaps or caps. Nevertheless, our results of operations can be affected by changes in interest rates with respect to the unhedged portion of our indebtedness that bears interest at floating rates, which typically bear a spread over EURIBOR, SOFR or over the alternative rates replacing these. Our results of operations may also be affected when we refinance our corporate debt in the future, since interest rates at the time of refinancing may be higher than current interest rates in our existing facilities.

Electricity market prices

As previously discussed, our solar assets in Spain receive revenue from the sale of electricity at market prices in addition to regulated revenue. Regulated revenues are revised periodically to reflect the difference between expected and actual market prices if the difference is higher than a pre-defined threshold. Additionally, our assets in Italy have contracted revenues through a regulated feed-in premium in addition to merchant revenues for the energy sold to the wholesale market.

Furthermore, we currently have three assets with merchant revenues (Chile PV 1 and Chile PV 3, where we have a 35% ownership, and Lone Star II, where we have a 49% ownership) and one asset with partially contracted revenues (Chile PV 2, where we have a 35% ownership). Our exposure to merchant electricity prices represents less than 2% of our portfolio² in terms of Adjusted EBITDA. At Lone Star II we are analyzing, together with our partner, the option to repower the asset in the context of the IRA, at a point in time to be determined.

Due to low electricity prices in Chile, the project debt of Chile PV 1&2, where we own a 35% equity interest, are under an event of default. Chile PV 1 was not able to maintain the minimum required cash in its debt service reserve account as of September 30, 2023. As a result, although we do not expect an acceleration of the debt to be declared by the credit entities, Chile PV 1 did not have an unconditional right to defer the settlement of the debt for at least twelve months and the project debt was classified as current in our interim consolidated financial statements. In addition, in October 2023, Chile PV 2 did not make its debt service payment. We are in conversations with the banks, together with our partner, regarding a potential waiver. The value of the net assets contributed by Chile PV 1&2 to the consolidated financial statements, excluding non-controlling interest, are approximately $3.5 million as of September 30, 2023.

Key Financial Measures

We regularly review a number of financial measurements and operating metrics to evaluate our performance, measure our growth and make strategic decisions. In addition to traditional IFRS performance measures, such as total revenue, we also consider Adjusted EBITDA.

Adjusted EBITDA is calculated as profit/(loss) for the period attributable to the parent company, after adding back loss/(profit) attributable to non-controlling interest, income tax expense, financial expense (net), depreciation, amortization and impairment charges of entities included in the Consolidated Condensed Interim Financial Statements and depreciation and amortization, financial expense and income tax expense of unconsolidated affiliates (pro-rata of our equity ownership).

Our management believes Adjusted EBITDA is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with an additional tool to compare business performance across companies and across periods. EBITDA is widely used by investors to measure a company’s operating performance without regard to items such as interest expense, taxes, depreciation and amortization, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired. Adjusted EBITDA is widely used by other companies in our industry.

² Calculated as a percentage of our Adjusted EBITDA in 2022.

46

The non-GAAP financial measures including Adjusted EBITDA may not be comparable to other similarly titled measures of other companies and has limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our operating results as reported under IFRS as issued by the IASB. Non-GAAP financial measures and ratios are not measurements of our performance or liquidity under IFRS as issued by the IASB and should not be considered as alternatives to operating profit or profit for the period or any other performance measures derived in accordance with IFRS as issued by the IASB or any other generally accepted accounting principles or as alternatives to cash flow from operating, investing or financing activities. Adjusted EBITDA excludes the impact of cash costs of financing activities and taxes, and the effects of changes in operating working capital balances, and therefore are not necessarily indicative of operating profit or cash flow from operations as determined under IFRS GAAP.

Note:

(1)   Adjusted EBITDA is not a measure of performance under IFRS as issued by the IASB and you should not consider Adjusted EBITDA as an alternative to operating income or profits or as a measure of our operating performance, cash flows from operating, investing and financing activities or as a measure of our ability to meet our cash needs or any other measures of performance under generally accepted accounting principles. We believe that Adjusted EBITDA is a useful indicator of our ability to incur and service our indebtedness and can assist securities analysts, investors and other parties to evaluate us. Adjusted EBITDA and similar measures are used by different companies for different purposes and are often calculated in ways that reflect the circumstances of those companies. Adjusted EBITDA may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results. See “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Financial Measures”.

Operational Metrics

In addition to the factors described above, we closely monitor the following key drivers of our business sectors’ performance to plan for our needs, and to adjust our expectations, financial budgets and forecasts appropriately.

• MW in operation in the case of Renewable energy and Efficient natural gas and heat assets, miles in operation in the case of Transmission lines and Mft³ per day in operation in the case of Water assets, are indicators which provide information about the installed capacity or size of our portfolio of assets.

• Production measured in GWh in our Renewable energy and Efficient natural gas and heat assets provides information about the performance of these assets.

• Availability in the case of our Efficient natural gas and heat assets, Transmission lines and Water assets also provides information about the performance of the assets. In these business segments revenues are based on availability, which is the time during which the asset was available to our client totally or partially divided by contracted availability or budgeted availability, as applicable.

Production in the renewable business sector increased by 5.5% in the nine-month period ended September 30, 2023, compared to the same period of the previous year. The increase was largely due to the increase in production in our solar assets in Spain, where solar radiation was higher in the period, and to the contribution from the assets recently consolidated or which have entered into operation recently, including Chile PV 3, La Tolua, Tierra Linda, Albisu and Italy PV 4, bringing approximately 144.4 GWh of additional electricity generation in the nine-month period ended September 30, 2023.

In our solar assets in the U.S. production increased by 6.6% in the nine-month period ended September 30, 2023, compared to the same period of the previous year. The increase was mainly due to greater availability of the storage system in Solana in the nine-month period ended September 30, 2023 compared to the first nine months of 2022. Solar radiation for the period was in line with the previous year (slightly lower in Mojave). On the other hand, production decreased by 10.4% in our wind assets in the U.S., due to lower wind resource in the nine-month period ended September 30,2023 compared to the same period of 2022. Production also decreased at Coso mostly due to scheduled maintenance stops and to the snow storm in California in the first quarter of 2023.

In Chile, production at our PV assets was lower in the nine-month period ended September 30, 2023 compared to the same period of the previous year mainly as a result of higher curtailments. At our wind assets in Uruguay, production increased by 4.9% due to better wind resource.

In Spain, production at our solar assets increased by 16.8% in the nine-month period ended September 30, 2023 as a result of better solar radiation compared to the same period of the previous year.

In Kaxu, production decreased by 23.6% compared to the same period of the previous year due to an outage of the plant. In the third quarter, a scheduled turbine major overhaul was carried out by Siemens, the original equipment manufacturer and took approximately 30 days longer than expected. After re-starting production, at the end of September, a problem was found in the turbine, likely related to the major overhaul. Siemens is currently performing repairs in some elements of the turbine and we expect such repairs to continue until at least December 2023. We expect part of the damage and the business interruption to be covered by our insurance property policy, after 60-day deductibles. We also expect to seek to recover part of the costs from Siemens.

In our efficient natural gas and heat segment availability decreased in the nine-month period ended September 30, 2023 mostly due to the scheduled major overhaul performed in the turbines at ACT. Since this major maintenance was scheduled, it did not impact revenue.

Our Water assets and Transmission lines, for which revenue is based on availability, continued to achieve very high levels of availability in the first nine months of 2023.

Comparison of the Nine-Month Periods Ended September 30, 2023 and 2022

The significant variances or variances of the significant components of the results of operations are discussed in the following section.

Revenue

Revenue remained stable at $858.6 million for the nine-month period ended September 30, 2023, compared to $858.4 million for the nine-month period ended September 30, 2022.

51

Revenue was higher at our solar assets in the U.S. due to higher electricity production as previously explained. Revenue also increased in our transmission lines in the nine-month period ended September 30, 2023 compared to the same period of the previous year mostly as a result of inflation adjustments to tariffs, including a positive tariff adjustment in Chile TL 3 corresponding to previous years, which was published in the second quarter of 2023. In addition, revenue also increased due to the assets recently consolidated and assets that entered in operation recently, which together represented a total of $7.0 million of additional revenue in the nine-month period ended September 30, 2023 compared to the same period of the previous year. These effects were partially offset by the decrease of $15.8 million in revenue at our solar assets in Spain in spite of higher production during the period, primarily due to lower electricity prices net of its corresponding accounting provision (see “Factors Affecting the Comparability of Our Results of Operations—Electricity market prices”). Revenue also decreased at Kaxu where production for the nine-month period ended September 30, 2023 was lower than in the same period from previous year as previously explained.

Other operating income

The following table sets forth our Other operating income for the nine-month periods ended September 30, 2023, and 2022:

	Nine-month period ended September 30,
Other operating income	2023		2022
	($ in millions)
Grants	$	44.1	$	44.4
Insurance proceeds and other		13.3		10.5
Total	$	57.4	$	54.9

“Grants” represent the financial support provided by the U.S. Department of the Treasury to Solana and Mojave and consist of an ITC Cash Grant and an implicit grant related to the below market interest rates of the project loans with the Federal Financing Bank. Grants were stable for the nine-month period ended September 30, 2023, compared to the same period of the previous year.

“Insurance proceeds and other” for the nine-month period ended September 30, 2023 included $4.6 million resulting from the sale of part of our equity interest in our development company in Colombia to a partner who now holds a 50% equity interest, with joint control. This gain was the main reason for the increase compared to same period of the previous year.

Employee benefit expenses

Employee benefit expenses increased by 29.4% to $76.1 million for the nine-month period ended September 30, 2023, compared to $58.8 million for the nine-month period ended September 30, 2022 mainly due to the internalization of the operation and maintenance services at Kaxu and at our solar assets in Spain.

Depreciation, amortization and impairment charges

Depreciation, amortization and impairment charges decreased by 17.0% to $310.5 million for the nine-month period ended September 30, 2023, compared to $374.1 million for the nine-month period ended September 30, 2022. The decrease was mainly due to the impairment loss recorded at Solana in the nine-month period ended September 30, 2022, for $41.2 million with no corresponding amount in the same period of 2023. The decrease was also due to a decrease of the expected credit loss impairment provision at ACT. IFRS 9 requires impairment provisions to be based on the expected credit loss of the financial assets in addition to actual credit losses. ACT recorded an increase in the credit loss impairment provision of $1.1 million for the nine-month period ended September 30, 2023, while for the nine-month period ended September 30, 2022, it recorded an increase in the credit loss impairment provision of $22.8 million. On the other hand, these effects on depreciation, amortization and impairment were partially offset by increased charges due to the consolidation of assets recently acquired or which entered in operation recently.

Other operating expenses

The following table sets forth our Other operating expenses for the nine-month periods ended September 30, 2023 and 2022:

	Nine-month period ended September 30,
Other operating expenses	2023						2022
	$ in millions			% of revenue			$ in millions			% of revenue
Raw materials and consumables used	$	(25.0	)		2.9	%	$	(13.7	)		1.6	%
Leases and fees		(9.8	)		1.1	%		(8.6	)		1.0	%
Operation and maintenance		(87.8	)		10.3	%		(106.1	)		12.4	%
Independent professional services		(31.3	)		3.7	%		(28.1	)		3.3	%
Supplies		(28.2	)		3.3	%		(45.7	)		5.3	%

Other expenses		(13.3	)		1.5	%		(11.2	)		1.3	%
Total	$	(237.9	)		27.7	%	$	(261.4	)		30.5	%

Other operating expenses decreased by 8.9% to $237.9 million for the nine-month period ended September 30, 2023, compared to $261.4 million for the nine-month period ended September 30, 2022, mainly due to lower operation and maintenance costs and lower cost of supplies.

Our operation and maintenance costs decreased during the nine-month period ended September 30, 2023, compared to the same period of the previous year mainly due to lower O&M costs in Spain, where these services have been internalized and are now provided by employees of Atlantica, with the cost classified in “Employee benefit” expenses. In addition, the cost of supplies decreased mostly due to lower price of electricity in our assets in Spain and insurance costs decreased due to lower fees particularly in our U.S. solar assets.

On the other hand, the cost of raw materials increased in the subsidiaries which are now performing the operation and maintenance which was previously subcontracted, as these costs are now assumed directly by subsidiaries of Atlantica.

Operating profit

As a result of the above-mentioned factors, operating profit increased by 33.1% to $291.5 million for the nine-month period ended September 30, 2023, compared with $219.0 million for the nine-month period ended September 30, 2022.

Financial income and financial expense

Financial income

The following table sets forth our Financial income for the nine-month periods ended September 30, 2023, and 2022:

	For the Nine-month period ended September 30,
	2023		2022
Financial income	($ in thousands)
Interest income on deposits	$	15.1		3.8
Interest income from loans and credits		2.0		1.0
Interest rate gains on derivatives: cash flow hedges		0.3		1.1
Total	$	17.4		5.9

Financial income increased from $5.9 million for the nine-month period ended September 30, 2022 to $17.4 million for the nine-month period ended September 30, 2023 mostly due to higher remuneration of deposits resulting from higher interest rates.

Financial expense

The following table sets forth our Financial expense for the nine-month periods ended September 30, 2023, and 2022:

	For the Nine-month period ended September 30,
Financial expense(1)	2023			2022
	($ in millions)
Interest on loans and notes	$	(260.9	)	$	(211.4	)
Interest rates gains / (losses) derivatives: cash flow hedges		17.8			(31.7	)
Total	$	(243.1	)	$	(243.1	)

(1) Classification within Financial expense has been revised to show a more meaningful classification of Financial expense following the increase in interest rates. Prior period classification has been revised accordingly.

Financial expense remained stable at $243.1 million for the nine-month period ended September 30, 2023, and for the nine-month period ended September 30, 2022.

“Interest on loans and notes” expense increased in the nine-month period ended September 30, 2023 when compared to the nine-month period ended September 30, 2022 mainly as a result of higher interest rates in our variable rate debt. This effect was offset by the increase of “Interest rate gains / (losses) on derivatives: cash flow hedges”, where we record transfers from equity to the income statement when the hedged item impacts profit and loss and which was a $17.2 million gain in the nine-month period ended September 30, 2023 while it was a $31.5 million loss in the nine-month period ended September, 2022, also due to the increase in the reference rates in the nine-month period ended September 30, 2023, compared to the same period of the previous year.

Net exchange differences

Net exchange differences decreased to a $0.2 million loss in the nine-month period ended September 30, 2023 compared to a $13.8 million income in the same period of the previous year. The decrease was mainly due to the change in fair value of caps hedging our net cash flows in euros, which was largely stable in the nine-month period ended September, 2023 while it increased in the nine-month period ended September, 2022.

Other financial income/(expense), net

The following table sets forth our Other financial income/(expense), net for the nine-month periods ended September 30, 2023, and 2022:

54

	Nine-month period ended September 30,
Other financial expense, net(1)	2023			2022
	($ in millions)
Other financial income	$	7.8		$	15.1
Other financial expense		(19.8	)		(16.6	)
Total	$	(12.0	)	$	(1.5	)

(1) Classification within Other financial income / (expense), net has been revised to show a more meaningful classification of Other financial income / (expense), net following the increase in interest rates. Prior period classification has been revised accordingly.

Other financial income/(expense), net increased to a net expense of $12.0 million for the nine-month period ended September 30, 2023, compared to a net expense of $1.5 million for the nine-month period ended September 30, 2022.

Other financial income in the nine-month period ended September 30, 2023, primarily includes an income of $3.8 million corresponding to the change in the fair value of the conversion option of the Green Exchangeable Notes in the period, (compared to $6.8 million in the nine-month period ended September 30, 2022). Other financial income also includes a non-monetary change to the fair value of derivatives of Kaxu for which hedge accounting is not applied for $1.1 million (compared to $6.2 million in the nine-month period ended September 30, 2022 and a one-time income related to the extension in the maturity of the Green Project Finance, which qualifies as a refinancing from an accounting perspective.

Other financial expense increased in the nine-month period ended September 30, 2023, mainly due to the financial impact related to the electricity market prices provision recorded at our solar assets in Spain. This is a long-term provision recorded at present value in accordance with the effective interest method, which progressively accrues a financial expense. Other financial expense also includes expenses for guarantees and letters of credit, wire transfers, other bank fees and other minor financial expenses.

Share of profit of associates carried under the equity method decreased to $6.9 million for the nine-month period ended September 30, 2023, compared to $20.7 million for the nine-month period ended September 30, 2022 primarily due to a lower profit at Vento II, resulting from lower production and a lower price at Lone Star II after its PPA expired in January 2023.

Profit before income tax

As a result of the previously mentioned factors, we reported a profit before income tax of $60.5 million for the nine-month period ended September 30, 2023, compared to a profit before income tax of $14.8 million for the nine-month period ended September 30, 2022.

Income tax

The effective tax rate for the periods presented has been established based on management’s best estimates. For the nine-month period ended September 30, 2023, income tax amounted to an expense of $11.6 million, with a profit before income tax of $60.5 million. For the nine-month period ended September 30, 2022, income tax amounted to an expense of $13.0 million, with profit before income tax of $14.8 million. The effective tax rate differs from the nominal tax rate mainly due to permanent tax differences in some jurisdictions.

Profit attributable to non-controlling interests

Profit attributable to non-controlling interests decreased to $2.9 million for the nine-month period ended September 30, 2023 compared to $11.3 million for the nine-month period ended September 30, 2022. Profit attributable to non-controlling interests corresponds to the portion attributable to our partners in the assets that we consolidate (Kaxu, Skikda, Solaben 2 & 3, Solacor 1 & 2, Seville PV, Chile PV 1, Chile PV 2, Chile PV 3 and Tenes). The decrease in profit attributable to non-controlling interest was mainly due to the loss reported in Kaxu resulting from lower production as previously explained.

55

Profit attributable to the parent company

As a result of the previously mentioned factors, profit attributable to the parent company was $46.1 million for the nine-month period ended September 30, 2023, compared to a loss of $9.5 million for the nine-month period ended September 30, 2022.

Segment Reporting

We organize our business into the following three geographies where the contracted assets and concessions are located: North America, South America and EMEA. In addition, we have identified four business sectors based on the type of activity: Renewable energy, Efficient natural gas and heat, Transmission and Water. We report our results in accordance with both criteria.

Note:

(1) Adjusted EBITDA is not a measure of performance under IFRS as issued by the IASB and you should not consider Adjusted EBITDA as an alternative to operating income or profits or as a measure of our operating performance, cash flows from operating, investing and financing activities or as a measure of our ability to meet our cash needs or any other measures of performance under generally accepted accounting principles. We believe that Adjusted EBITDA is a useful indicator of our ability to incur and service our indebtedness and can assist securities analysts, investors and other parties to evaluate us. Adjusted EBITDA and similar measures are used by different companies for different purposes and are often calculated in ways that reflect the circumstances of those companies. Adjusted EBITDA may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results.

Note:

(1) GWh produced includes 30% of the production from Monterrey and our 49% of Vento II wind portfolio production since its acquisition.

(2) Availability includes only those assets that have revenue based on availability.

(3) Includes curtailment production in wind assets for which we receive compensation.

North America

Revenue increased by 4.6% to $338.7 million for the nine-month period ended September 30, 2023, compared to $323.7 million for the nine-month period ended September 30, 2022, and Adjusted EBITDA increased by 1.0% to $260.7 million for the nine-month period ended September 30, 2023, compared to $258.1 million for the nine-month period ended September 30, 2022. The increase of Revenue was mainly due to higher electricity production in our solar assets in the U.S. as previously discussed, together with higher revenue at ACT (see “Efficient natural gas & heat” below), which was partially offset by lower revenue at Coso due to lower production. Adjusted EBITDA increased mainly due to the increase in revenue, which was partially offset by lower EBITDA at Vento II, caused by lower production and lower prices at Lone Star II after the end of its PPA.

South America

Revenue increased by 14.5% to $140.3 million for the nine-month period ended September 30, 2023, compared to $122.5 million for the nine-month period ended September 30, 2022. The increase was mainly due to assets recently consolidated and assets which entered in operation recently. Revenue also increased due to indexation to inflation in our revenue in transmission lines, including a positive tariff adjustment in Chile TL 3 corresponding to previous years which was published in the second quarter of 2023, and in wind assets in Uruguay. This increase was partially offset by lower revenue at our PV assets in Chile, where production decreased and electricity prices were lower. Adjusted EBITDA increased by 17.9% to $112.1 million for the nine-month period ended September 30, 2023, compared to $95.1 million for the nine-month period ended September 30, 2022, mostly due to the increase in revenue and to a $4.5 million gain from the sale of part of our equity interest in our development company in Colombia to a partner in the first quarter of 2023.

EMEA

Revenue decreased to $379.6 million for the nine-month period ended September 30, 2023, which represents a decrease of 7.9% compared to $412.2 million for the nine-month period ended September 30, 2022. The decrease was mainly due to lower revenue at our solar assets in Spain in spite of higher production during the period, primarily due to lower electricity prices net of its corresponding accounting provision (see “Factors Affecting the Comparability of Our Results of Operations—Electricity market prices”). The decrease was also due to lower revenue at Kaxu resulting from lower production as previously explained.

Adjusted EBITDA decreased to $254.5 million for the nine-month period ended September 30, 2023, which represents a decrease of 8.3% compared to $277.4 million for the nine-month period ended September 30, 2022. Adjusted EBITDA decreased mainly due to lower revenue at Kaxu. Adjusted EBITDA at our solar assets in Spain decreased less than revenue mainly due to lower costs of supplies in our assets in Spain, resulting mostly from a decrease in the price of electricity.

(2) GWh produced includes 30% of the production from Monterrey.

Renewable energy

Revenue decreased to $640.1 million for the nine-month period ended September 30, 2023, which represents a 1.9% decrease compared to $652.8 million for the nine-month period ended September 30, 2022. The decrease in revenue was primarily due to lower revenue at our solar assets in Spain and at Kaxu as previously discussed. On the other hand, revenue increased at our solar assets in the U.S. due to higher electricity production as previously explained and at our wind assets in Uruguay due to higher production and price indexation to inflation, together with the contribution of assets recently consolidated.

58

Adjusted EBITDA decreased to $460.4 million for the nine-month period ended September 30, 2023, which represents a decrease of 2.0% compared to $469.8 million for the nine-month period ended September 30, 2022. The decrease in Adjusted EBITDA was mainly due to the decrease in revenue and to lower EBITDA at Vento II, as previously explained. This decrease was partially offset by lower costs of supplies in our assets in Spain resulting from a decrease in the price of electricity.

Efficient natural gas & heat

Revenue increased by 3.8% to $85.0 million for the nine-month period ended September 30, 2023, compared to $81.9 million for the nine-month period ended September 30, 2022, while Adjusted EBITDA decreased by 0.4% to $66.5 million for the nine-month period ended September 30, 2023 compared to $66.8 million for the nine-month period ended September 30, 2022. Revenue increased at ACT with Adjusted EBITDA remaining stable mainly due to higher operation and maintenance costs, since there is a portion of revenue related to operation and maintenance services plus a margin.

Transmission lines

Revenue increased by 10.2% to $91.8 million for the nine-month period ended September 30, 2023, compared to $83.3 million for the nine-month period ended September 30, 2022, while Adjusted EBITDA increased by 10.7% to $73.3 million for the nine-month period ended September 30, 2023 compared to $66.2 million for the nine-month period ended September 30, 2022. The increase in revenue and Adjusted EBITDA was mainly due to tariff indexation to inflation including a positive tariff adjustment in Chile TL 3 corresponding to previous years.

Water

Revenue and Adjusted EBITDA remained stable at $41.7 million and $27.1 million respectively for the nine-month period ended September 30, 2023, compared to $40.4 million and $27.8 million respectively for the nine-month period ended September 30, 2022.

Liquidity and Capital Resources

Our principal liquidity and capital requirements consist of the following:

• debt service requirements on our existing and future debt;

• cash dividends to investors; and

• investments in new assets and companies and operations (See “Recent Investments”).

As a normal part of our business, depending on market conditions, we will from time to time consider opportunities to repay, redeem, repurchase or refinance our indebtedness: Changes in our operating plans, lower than anticipated sales, increased expenses, acquisitions or other events may cause us to seek additional debt or equity financing in future periods. There can be no guarantee that financing will be available on acceptable terms or at all. Debt financing, if available, could impose additional cash payment obligations and additional covenants and operating restrictions. In addition, any of the items discussed in detail under “Part I, Item 3.D.—Risk Factors” in our Annual Report and other factors may also significantly impact our liquidity.

Interest accrues at a rate per annum equal to 1.96%. If at any time the rating of these senior secured notes is below investment grade, the interest rate thereon would increase by 100 basis points until such notes are again rated investment grade.

Our obligations under the 2020 Green Private Placement rank equal in right of payment with our outstanding obligations under the Revolving Credit Facility, the Note Issuance Facility 2020, the Green Senior Notes and the Credit Line with Export Development Canada.

The program had an original maturity of twelve months and has been extended twice, for annual periods. The program allows Atlantica to issue short term notes for up to €50 million, with such notes having a tenor of up to two years. As of September 30, 2023, we had €28.0 million ($29.6 million) issued and outstanding under the Commercial Paper Program at an average cost of 4.9% maturing on or before February 2024.

Covenants, restrictions and events of default

The Note Issuance Facility 2020, the 2020 Green Private Placement, the Green Senior Notes and the Revolving Credit Facility contain covenants that limit certain of our and the guarantors’ activities. The Note Issuance Facility 2020, the 2020 Green Private Placement and the Green Exchangeable Notes also contain customary events of default, including a cross-default with respect to our indebtedness, indebtedness of the guarantors thereunder and indebtedness of our material non-recourse subsidiaries (project-subsidiaries) representing more than 25% of our cash available for distribution distributed in the previous four fiscal quarters, which in excess of certain thresholds could trigger a default. Additionally, under the 2020 Green Private Placement, the Revolving Credit Facility and the Note Issuance Facility 2020 we are required to comply with a leverage ratio of our corporate indebtedness excluding non-recourse project debt to our cash available for distribution of 5.00:1.00 (which may be increased under certain conditions to 5.50:1.00 for a limited period in the event we consummate certain acquisitions).

Furthermore, our corporate debt agreements contain customary change of control provisions (as such term is defined in each of those agreements) or similar provisions. Under the Revolving Credit Facility, a change of control without required lenders’ consent would trigger an event of default. In the other corporate debt agreements or securities, a change of control or similar provision without the consent of the relevant required holders would trigger the obligation to make an offer to purchase the respective notes at (i) 100% of the principal amount in the case of the 2020 Green Private Placement and Green Exchangeable Notes and at (ii) 101% of the principal amount in the case of the Note Issuance Facility 2020 and the Green Senior Notes. In the case of the Green Senior Notes, such prepayment obligation would be triggered only if there is a credit rating downgrade by any of the agencies.

 B) At-The-Market Program

On February 28, 2022, we established an “at-the-market program” and entered into the Distribution Agreement with BofA Securities, Inc., MUFG Securities Americas Inc. and RBC Capital Markets LLC, as our sales agents, under which we may offer and sell from time to time up to $150 million of our ordinary shares, including in “at-the-market” offerings under our shelf registration statement on Form F-3 filed with the SEC on August 3, 2021, and a prospectus supplement that we filed on February 28, 2022. During the nine-month period ended September 30, 2023, we did not issue and sell any ordinary shares under the program.

C) Project debt refinancing

Green Project Finance

In June 2023 we extended the maturity of the debt of Logrosan Solar Inversiones, S.A.U., the sub-holding company of Solaben 1&6 and Solaben 2&3, from April 2025 to December 2028. The facility is a green project financing euro-denominated agreement that had an initial notional of €140 million of which approximately 37% is amortized between the signing date and maturity. As of June 30, 2023, the amount outstanding was €111 million, of which €23.2 million is progressively amortized with a two-year grace period and the remaining €87.8 million is expected to be refinanced at maturity. The Green Project Finance is guaranteed by the shares of Logrosan and its lenders have no recourse to Atlantica corporate level.

The interest rate for the loans accrues at a rate per annum equal to the sum of six-month EURIBOR plus a margin of 3.25%. The principal is 100% hedged for the life of the loan through a combination of the following instruments:

- a pre-existing cap with a 0% strike with notional of €115.9 million starting by June 2023 and decreasing over time until December 2025.

- a cap with a 3.5% strike with initial notional of €2.5 million starting in June 2023. The notional increases progressively until June 2025 up to €110.9 million and decreases progressively thereafter until maturity to ensure that the principal hedged stays at 100% over the life of the loan.

The Green Project Finance permits cash distribution to shareholders twice per year if the Logrosan sub-holding company debt service coverage ratio is at least 1.20x and the debt service coverage ratio of the sub-consolidated group of Logrosan and the Solaben 1 & 6 and Solaben 2 & 3 assets is at least 1.075x.

Like in previous refinancings, the financing agreement also includes a mechanism under which, in the case that electricity market prices are above certain levels defined in the contract, a reserve account should be established and funded on a six-month rolling basis for the additional revenue arising from the difference between actual prices and prices defined in the agreement. Under certain conditions, such amounts, if any, should be used for early prepayments upon regulatory parameters changes.

64

Solaben 2&3

In March 2023 we refinanced Solaben 2&3. We entered into two green senior euro-denominated loan agreements for the two assets with a syndicate of banks for a total amount of €198.0 million. The new project debt replaced the previous project loans and maturity was extended from December 2030 to June 2037.

The interest rate for the loans accrues at a rate per annum equal to the sum of six-month EURIBOR plus a margin of 1.50% between 2023 and June 2028, 1.60% between June 2028 and June 2033 and 1.70% from June 2033 onwards. The principal is 90% hedged for the life of the loan through a combination of the following instruments:

• a pre-existing cap with a 1.0% strike with notional of €115.1 million starting in March 2023 and decreasing over time until December 2025.

• a swap with a 3.16% strike with initial notional of €64.9 million starting in March 2023. The notional increases progressively until June 2026 and decreases progressively thereafter until maturity to ensure that the principal hedged stays at 90% over the life of the loan.

The financing agreement also includes a mechanism under which, in the case that electricity market prices are above certain levels defined in the contract, a reserve account should be established and funded on a six-month rolling basis for the additional revenue arising from the difference between actual prices and prices defined in the agreement. Under certain conditions, such amounts, if any, should be used for early prepayments upon regulatory parameters changes.

See “Item 5.B—Liquidity and Capital Resources—Financing Arrangements” in our Annual Report for further detail on the rest of our financing arrangements.

Uses of liquidity and capital requirements

Cash dividends to investors

We intend to distribute a significant portion of our cash available for distribution to shareholders on an annual basis less all cash expenses including corporate debt service and corporate general and administrative expenses and less reserves for the prudent conduct of our business (including, among other things, dividend shortfall as a result of fluctuations in our cash flows), on an annual basis. We intend to distribute a quarterly dividend to shareholders. Our board of directors may, by resolution, amend the cash dividend policy at any time. The determination of the amount of the cash dividends to be paid to shareholders will be made by our board of directors and will depend upon our financial condition, results of operations, cash flow, long-term prospects and any other matters that our board of directors deem relevant. Our board of directors may, by resolution, amend the cash dividend policy at any time.

Our cash available for distribution is likely to fluctuate from quarter to quarter and, in some cases, significantly as a result of the seasonality of our assets, the terms of our financing arrangements, maintenance and outage schedules, among other factors. Accordingly, during quarters in which our projects generate cash available for distribution in excess of the amount necessary for us to pay our stated quarterly dividend, we may reserve a portion of the excess to fund cash distributions in future quarters. During quarters in which we do not generate sufficient cash available for distribution to fund our stated quarterly cash dividend, if our board of directors so determines, we may use retained cash flow from other quarters, and other sources of cash to pay dividends to our shareholders.

Investments and Acquisitions

The acquisitions and investments detailed in “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Recent Investments” have been part of the use of our liquidity in 2022 and 2023. In addition, we have made investments in assets which are currently under development or construction.

We intend to grow our business through the development and construction of our project pipeline including expansion and repowering opportunities, as well as greenfield developments, third-party acquisitions and the optimization of our existing portfolio. We currently have a pipeline of assets under development of approximately 2.1 GW of renewable energy and 6.0 GWh of storage. Approximately 44% of the projects are PV, 42% storage 13% wind and 1% other projects, while 37% are expected to reach ready-to-build (“RTB”) in 2023-2024 or are in an advanced development stage and 63% are in an early stage. Also, 23% are expansion or repowering opportunities of existing assets and 77% greenfield developments.

Our uses of liquidity also include debt service and contractual obligations (refer to our Annual Report for further detail).

Net cash provided by operating activities

For the nine-month period ended September 30, 2023, net cash provided by operating activities was $333.9 million, a 35.3% decrease compared to $515.7 million in the nine-month period ended September 30, 2022. The decrease was mainly due to the negative impact of changes in working capital for $116.1 million in the nine-month period ended September 30, 2023 compared to a positive change in working capital for $47.7 million in the same period of the previous year:

- During the year 2022, in our assets in Spain we collected cash in line with the old parameters corresponding to the regulation in place at the beginning of the year 2022 and we were booking revenue in accordance with the new parameters published in draft form, which were lower. This caused a positive change in working capital of approximately $54 million in the nine-month period ended September 30, 2022. In the first quarter of 2023, collections at these assets in Spain were regularized, following the approval on December 14, 2022 of the new parameters for 2022, causing a negative change in working capital of approximately $58 million for the nine-month period ended September 30, 2023.

- Additionally, working capital in the nine-month period ended September 30, 2023, also includes a negative change due to lower collections in ACT of approximately $44 million compared to a positive change in working capital of approximately $28 million of the same period from previous year.

Net cash used in investing activities

For the nine-month period ended September 30, 2023, net cash used in investing activities amounted to $24.6 million and corresponded mainly to $76.0 million investments in new assets as well as development and construction of and investments in existing assets, including investments and replacements in Solana. These cash outflows were partially offset by $28.9 million of dividends received from associates under the equity method, of which $10.9 million corresponded to Amherst by AYES Canada, most of which were paid to our partner in this project, and $11.1 million corresponded to Vento II.

For the nine-month period ended September 30, 2022, net cash used in investing activities amounted to $48.1 million and corresponded mainly to $45.6 million paid for acquisitions consisting mainly of Chile TL4, Chile PV 3 and Italy PV4, investments in assets under construction for $30.4 million and other investments in existing assets for $27.9 million, including the investments and replacements in Solana. These cash outflows were partially offset by $56.2 million of dividends received from associates under the equity method, of which $22.0 million corresponded to Amherst Island Partnership by AYES Canada, most of which were paid to our partner in this project.

Net cash (used in) financing activities

For the nine-month period ended September 30, 2023, net cash used in financing activities amounted to $309.9 million and includes the scheduled repayment of principal of our project financing for $154.5 million and dividends paid to shareholders for $155.1 million and non-controlling interests for $25.8 million. These cash outflows were partially offset by the proceeds of corporate debt mainly related to the issuance of commercial paper for a net amount of $19.2 million and the Revolving Credit Facility, which was drawn for an additional $10 million in the nine-month period ended September 30, 2023.

For the nine-month period ended September 30, 2022, net cash used in financing activities amounted to $263.1 million and includes the repayment of principal of our project financing for $196.3 million and dividends paid to shareholders for $151.5 million and non-controlling interests for $26.4 million. These cash outflows were partially offset by the proceeds from the equity raised under the at-the-market programs for a net amount of $113.2 million.

Item 3. Quantitative and Qualitative Disclosure about Market Risk

Our activities are undertaken through our segments and are exposed to market risks that include foreign exchange risk, interest rate risk, credit risk, liquidity risk, electricity price risk and country risk. Our objective is to protect Atlantica  against material economic exposures and variability of results from those risks. Risk is managed by our Risk Management and Finance Departments in accordance with mandatory internal management rules. The internal management rules provide written policies for the management of overall risk, as well as for specific areas, such as foreign exchange rate risk, interest rate risk, credit risk and liquidity risk, among others. Our internal management policies also define the use of hedging instruments and derivatives and the investment of excess cash. We use swaps and options on interest rates and foreign exchange rates to manage certain of our risks. None of the derivative contracts signed has an unlimited loss exposure.

The following table outlines Atlantica’s market risks and how they are managed:

Market Risk	Description of Risk	Management of Risk
Foreign exchange risk	We are exposed to foreign currency risk – including euro, Canadian dollar, South African rand,  Colombian peso and Uruguayan peso – related to operations and certain foreign currency debt. Our presentation currency and the functional currency of most of our subsidiaries is the U.S. dollar, as most of our revenue and expenses are denominated or linked to U.S. dollars. All our companies located in North America, with the exception of Calgary, whose revenue is in Canadian dollars, and most of our companies in South America have their revenue and financing contracts signed in or indexed totally or partially to U.S. dollars. Our solar power plants in Europe have their revenue and expenses denominated in euros; Kaxu, our solar plant in South Africa, has its revenue and expenses denominated in South African rand, La Sierpe, La Tolua and Tierra Linda, our solar plants in Colombia, have their revenue and expenses denominated in Colombian pesos and Albisu, our solar plant in Uruguay, has its revenue denominated in Uruguayan pesos, with a maximum and a minimum price in US dollars.	The main cash flows in our subsidiaries are cash collections arising from long-term contracts with clients and debt payments arising from project finance repayment. Project financing is typically denominated in the same currency as that of the contracted revenue agreement, which limits our exposure to foreign exchange risk. In addition, we maintain part of our corporate general and administrative expenses and part of our corporate debt in euros which creates a natural hedge for the distributions we receive from our assets in Europe. To further mitigate this exposure, our strategy is to hedge cash distributions from our assets in Europe. We hedge the exchange rate for the net distributions in euros (after deducting interest payments and general and administrative expenses in euros). Through currency options, we have hedged 100% of our euro-denominated net exposure for the next 12 months and 75% of our euro-denominated net exposure for the following 12 months. We expect to continue with this hedging strategy on a rolling basis. The difference between the euro/U.S. dollar hedged rate for the year 2023 and the current rate reduced by 5% would create a negative impact on cash available for distribution of approximately $6 million. This amount has been calculated as the average net euro exposure expected for the years 2023 to 2026 multiplied by the difference between the average hedged euro /U.S. dollar rate for 2023 and the euro/U.S. dollar rate as of the date of this quarterly report reduced by 5%. Although we hedge cash-flows in euros, fluctuations in the value of the euro in relation to the U.S. dollar may affect our operating results. For example, revenue in euro-denominated companies could decrease when translated to U.S. dollars at the average foreign exchange rate solely due to a decrease in the average foreign exchange rate, in spite of revenue in the original currency being stable. Fluctuations in the value of the South African rand, the Colombian peso and the Uruguayan peso with respect to the U.S. dollar may also affect our operating results. Apart from the impact of these translation differences, the exposure of our income statement to fluctuations of foreign currencies is limited, as the financing of projects is typically denominated in the same currency as that of the contracted revenue agreement.

68

Interest rate risk   We are exposed to interest rate risk on our variable-rate debt.   Interest rate risk arises mainly from our financial liabilities at variable interest rates4 (less than 10% of our consolidated debt currently). Interest rate risk may also arise in the future when we refinance our corporate debt, since interest rates at the moment of refinancing may be higher than current interest rates in our existing facilities.   The most significant impact on our Consolidated Condensed Interim Financial Statements related to interest rates corresponds to the potential impact of changes in EURIBOR or SOFR on the debt with interest rates based on these reference rates and on derivative positions.   In relation to our interest rate swaps positions, an increase in EURIBOR or SOFR above the contracted fixed interest rate would create an increase in our financial expense which would be positively mitigated by our hedges, reducing our financial expense to our contracted fixed interest rate. However, an increase in EURIBOR or SOFR that does not exceed the contracted fixed interest rate would not be offset by our derivative position and would result in a stable net expense recognized in our consolidated income statement.   In relation to our interest rate options positions, an increase in EURIBOR, or SOFR above the strike price would result in higher interest expenses, which would be positively mitigated by our hedges, reducing our financial expense to our capped interest rate. However, an increase in these rates of reference below the strike price would result in higher interest expenses.
Our assets largely consist of long duration physical assets, and financial liabilities consist primarily of long-term fixed-rate debt or floating-rate debt that has been swapped to fixed rates with interest rate financial instruments to minimize the exposure to interest rate fluctuations.   We use interest rate swaps and interest rate options (caps) to mitigate interest rate risk. As of September 30, 2023, approximately 93% of our consolidated debt has fixed rates or is hedged. As of that same date, 92% of our project debt and approximately 96% of our corporate debt either has fixed interest rates or has been hedged with swaps or caps. Our revolving credit facility has variable interest rates and is not hedged as further described in “Item 5.B— Operating and Financial Review and Prospects—Liquidity and Capital Resources— Corporate debt agreements—Revolving Credit Facility”;   In the event that EURIBOR or SOFR had risen by 25 basis points as of September 30, 2023, with the rest of the variables remaining constant, the effect in the consolidated income statement would have been a loss of $0.7 million and an increase in hedging reserves of $17.5 million. The increase in hedging reserves would be mainly due to an increase in the fair value of interest rate swaps designated as hedges.

69

Credit risk	We are exposed to credit risk mainly from operating activities, the maximum exposure of which is represented by the carrying amounts reported in the statements of financial position. We are exposed to credit risk if counterparties to our contracts, trade receivables, interest rate swaps, or foreign exchange hedge contracts are unable to meet their obligations. The credit rating of Eskom is currently CCC+ from S&P , Caa1 from Moody’s and B from Fitch. Eskom is the off-taker of our Kaxu solar plant, a state-owned, limited liability company, wholly owned by the Republic of South Africa. In addition, Pemex’s credit rating is currently BBB from S&P, B1 from Moody’s and B+ from Fitch. We have experienced delays in collections in the past, especially since the second half of 2019, which have been significant in certain quarters.	The diversification by geography and business sector helps to diversify credit risk exposure by diluting our exposure to a single client. In the case of Kaxu, Eskom’s payment guarantees to our Kaxu solar plant are underwritten by the South African Department of Mineral Resources and Energy, under the terms of an implementation agreement. The credit ratings of the Republic of South Africa as of the date of this quarterly report are BB-/Ba2/BB- by S&P, Moody’s and Fitch, respectively. In the case of Pemex, we continue to maintain a proactive approach including fluent dialogue with our client.
Liquidity risk	We are exposed to liquidity risk for financial liabilities. Our liquidity at the corporate level depends on distribution from the project level entities, most of which have project debt in place. Distributions are generally subject to the compliance with covenants and other conditions under our project finance agreements.	The objective of our financing and liquidity policy is to ensure that we maintain sufficient funds to meet our financial obligations as they fall due. Project finance borrowing permits us to finance projects through project debt and thereby insulate the rest of our assets from such credit exposure. We incur project finance debt on a project-by-project basis or by groups of projects. The repayment profile of each project is established based on the projected cash flow generation of the business. This ensures that sufficient financing is available to meet deadlines and maturities, which mitigates the liquidity risk. In addition, we maintain a periodic communication with our lenders and regular monitoring of debt covenants and minimum ratios. As of September 30, 2023, we had $441.1 million liquidity at the corporate level, comprised of $48.0 million of cash on hand at the corporate level and $393.1 million available under our Revolving Credit Facility. We believe that the Company’s liquidity position, cash flows from operations and availability under our revolving credit facility will be adequate to meet the Company’s financial commitments and debt obligations; growth, operating and maintenance capital expenditures; and dividend distributions to shareholders. Management continues to regularly monitor the Company’s ability to finance the needs of its operating, financing and investing activities within the guidelines of prudent balance sheet management.

70

Electricity price risk	We currently have three assets with merchant revenues (Chile PV 1 and Chile PV 3, where we have a 35% ownership, and Lone Star II, where we have a 49% ownership) and one asset with partially contracted revenues (Chile PV 2, where we have a 35% ownership). In addition, in several of the jurisdictions in which we operate including Spain, Chile and Italy we are exposed to remuneration schemes which contain both regulated incentives and market price components. In such jurisdictions, the regulated incentive or the contracted component may not fully compensate for fluctuations in the market price component, and, consequently, total remuneration may be volatile. In addition, operating costs in certain of our existing or future projects depend to some extent on market prices of electricity used for self-consumption and, to a lower extent, on market prices of natural gas. In Spain, for example, operating costs increased during 2021 and 2022 as a result of the increase in the price of electricity and natural gas.	We manage our exposure to electricity price risk by ensuring that most of our revenues are not exposed to fluctuations in electricity prices. As of September 30, 2023, assets with merchant exposure represent less than a 2%3 of our portfolio in terms of Adjusted EBITDA. Regarding regulated assets with exposure to electricity market prices, these assets have the right to receive a “reasonable rate of return” (see “Item 4—Information on the Company— Regulation”). As a result, fluctuations in market prices may cause volatility in results of operations and cash flows, but it should not affect the net value of these assets.
Country risk	We consider that Algeria and South Africa, which represent a small portion of the portfolio in terms of cash available for distribution, are the geographies with a higher political risk profile.	Most of the countries in which we have operations are OECD countries. In 2019, we entered into a political risk insurance agreement with the Multinational Investment Guarantee Agency for Kaxu. The insurance provides protection for breach of contract up to $47.0 million in the event that the South African Department of Mineral Resources and Energy does not comply with its obligations as guarantor. We also have a political risk insurance in place for two of our assets in Algeria for up to $37.2 million, including two years of dividend coverage. These insurance policies do not cover credit risk.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

In 2018, an insurance company covering certain Abengoa obligations in Mexico claimed certain amounts related to a potential loss. Atlantica reached an agreement under which Atlantica´s maximum theoretical exposure would in any case be limited to approximately $35 million, including $2.5 million to be held in an escrow account. In January 2019, the insurance company called on this $2.5 million from the escrow account and Abengoa reimbursed this amount. The insurance company could claim additional amounts if they faced new losses after following a process agreed between the parties and, in any case, Atlantica would only make payments if and when the actual loss has been confirmed and after arbitration if the Company initiates it. The Company used to have indemnities from Abengoa for certain potential losses, but such indemnities are no longer valid following the insolvency filing by Abengoa in February 2021.

In addition, during 2021 and 2022, several lawsuits were filed related to the February 2021 winter storm in Texas against among others Electric Reliability Council of Texas (ERCOT), two utilities in Texas and more than 230 individual power generators, including Post Oak Wind, LLC, the project company owner of Lone Star II, one of the wind assets in Vento II where the Company currently has a 49% equity interest. The basis for the lawsuit is that the defendants failed to properly prepare for cold weather, including failure to implement measures and equipment to protect against cold weather, and failed to properly conduct their operations before and during the storm.

Except as described above, Atlantica is not a party to any other significant legal proceedings other than legal proceedings (including administrative and regulatory proceedings) arising in the ordinary course of its business. Atlantica is party to various administrative and regulatory proceedings that have arisen in the ordinary course of business.

While Atlantica does not expect these proceedings, either individually or in combination, to have a material adverse effect on its financial position or results of operations, because of the nature of these proceedings Atlantica is not able to predict their ultimate outcomes, some of which may be unfavorable to Atlantica.

Nature of the business [Abstract]

Nature of the business

Note 1. - Nature of the business

Atlantica Sustainable Infrastructure plc (“Atlantica” or the “Company”) is a sustainable infrastructure company with a majority of its business in renewable energy assets. Atlantica currently owns, manages and invests in renewable energy, storage, efficient natural gas and heat, electric transmission lines and water assets focused on North America (the United States, Canada and Mexico), South America (Peru, Chile, Colombia and Uruguay) and EMEA (Spain, Italy, Algeria and South Africa).

Atlantica’s shares trade on the NASDAQ Global Select Market under the symbol “AY”.

In March 2023, the Company completed the process of transitioning O&M services for the assets in Spain where Abengoa was still the supplier to an Atlantica’ subsidiary (Note 5). After this transfer, the Company performs the O&M services with its own personnel for assets representing approximately 72% of the consolidated revenue in 2022. Abengoa currently provides O&M services for assets representing less than 5% of the consolidated revenue of the Company for the year ended December 31, 2022.

The following three assets that the Company had under construction during 2022, finished construction and reached COD in the first quarter of 2023:

- Albisu, a 10 MW PV asset wholly owned by the Company. Albisu is located in the city of Salto (Uruguay). The asset has a 15-year PPA with Montevideo Refrescos, S.R.L, a subsidiary of Coca-Cola Femsa., S.A.B. de C.V. The PPA is denominated in local currency with a maximum and minimum price in U.S. dollars and is adjusted monthly based on a formula referring to U.S. Producer Price Index (PPI), Uruguay’s Consumer Price Index (CPI) and the applicable UYU/U.S. dollar exchange rate.

- La Tolua and Tierra Linda, two wholly owned solar PV assets in Colombia with a combined capacity of 30 MW. Each plant has a 10-year PPA in local currency indexed to local inflation with Coenersa, the largest independent electricity wholesaler in Colombia.

During the year 2022, the Company completed the following investments:

- On January 17, 2022, the Company closed the acquisition of Chile TL4, a 63-mile transmission line and 2 substations in Chile for a total equity investment of $38.4 million (Note 5). The Company expects to expand the transmission line in 2024, which would represent an additional investment of approximately $8 million. The asset has fully contracted revenues in U.S. dollars, with inflation escalation and a 50-year remaining contract life. The off-takers are several mini-hydro plants that receive contracted or regulated payments.

- On April 4, 2022, the Company closed the acquisition of Italy PV 4, a 3.6 MW solar portfolio in Italy for a total equity investment of $3.7 million (Note 5). The asset has regulated revenues under a feed in tariff until 2031.

- On September 2, 2022, the Company completed its third investment through its Chilean renewable energy platform in a 73 MW solar PV plant, Chile PV 3, located in Chile, for $7.7 million corresponding to a 35% of equity interest (Note 5). The Company expects to install batteries with a capacity of approximately 100 MWh in 2024. Total investment including batteries is expected to be in the range of $15 million to $25 million depending on the capital structure. Part of the asset’s revenue is currently based on capacity payments. Adding storage would increase the portion of capacity payments.

- On November 16, 2022, the Company closed the acquisition of a 49% interest, with joint control, in an 80 MW portfolio of solar PV projects in Chile, Chile PMGD, which is currently under construction. Atlantica´s economic rights are expected to be approximately 70%. Total investment in equity and preferred equity is expected to be approximately $30 million and Commercial Operation Date (“COD”) is expected to be progressive in 2024. Revenue for these assets is regulated under the Small Distributed Generation Means Regulation Regime (“PMGD”) for projects with a capacity equal or lower than 9MW, which allows to sell electricity through a stabilized price.

The following table provides an overview of the main operating assets the Company owned or had an interest in as of September 30, 2023:

(*) Commercial Operation Date.

In October 2023, Chile PV 2, where the Company owns a 35% equity interest, did not make its debt service payment mainly due to the low electricity prices in Chile, which represents an event of default. The Company and its partner are in conversations with the banks regarding a potential waiver. In addition, Chile PV 1, where the Company owns a 35% equity interest, was not able to maintain the minimum required cash in its debt service reserve account during the third quarter of 2023 due to low electricity prices, which represents an event of default as of September 30, 2023. As a result, although the Company does not expect an acceleration of the debt to be declared by the credit entities, Chile PV 1 did not have an unconditional right to defer the settlement of the debt for at least twelve months and the project debt, which amounts to $49 million as of September 30, 2023 (Note 15), was classified as current in these Consolidated Condensed Interim Financial Statements in accordance with International Accounting Standards 1 (“IAS 1”), “Presentation of Financial Statements”.

Amounts included in these Consolidated Condensed Interim Financial Statements are all expressed in thousands of U.S. dollars, unless otherwise indicated.

These Consolidated Condensed Interim Financial Statements were approved by the Board of Directors of the Company on November 7, 2023.

Application of new accounting standards

a) Standards, interpretations and amendments effective from January 1, 2023, under IFRS-IASB, applied by the Company in the preparation of these Consolidated Condensed Interim Financial Statements:

The applications of these amendments have not had any impact on these Consolidated Condensed Interim Financial Statements.

In addition, the IASB published in May 2023 an amendment to IAS 12, “Income taxes”, to clarify the application of this standard arising from tax legislation enacted or substantively enacted in each country to implement the Pillar Two model rules in which it provides:

- a temporary exception to the accounting for deferred taxes in connection with the implementation of Pillar Two.

- qualitative and quantitative disclosures to enable users to understand the entities’ exposure to taxes that may arise from the Pillar Two model rules and/or the entity’s progress in its implementation.

The Company is currently working on analyzing the implications arising from this new regulation applicable for accounting periods commencing on or after December 31, 2023.

b) Standards, interpretations and amendments published by the IASB that will be effective for periods beginning on or after January 1, 2024:

The Company does not anticipate any significant impact on the Consolidated Condensed Interim Financial Statements derived from the application of the new standards and amendments that will be effective for annual periods beginning on or after January 1, 2024, although it is currently still in the process of evaluating such application.

The Company has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

Use of estimates

Some of the accounting policies applied require the application of significant judgment by management to select the appropriate assumptions to determine these estimates. These assumptions and estimates are based on the Company´s historical experience, advice from experienced consultants, forecasts and other circumstances and expectations as of the close of the financial period. The assessment is considered in relation to the global economic situation of the industries and regions where the Company operates, taking into account future development of its businesses. By their nature, these judgments are subject to an inherent degree of uncertainty; therefore, actual results could materially differ from the estimates and assumptions used. In such cases, the carrying values of assets and liabilities are adjusted.

The most critical accounting policies, which require significant management estimates and judgment are as follows:

Estimates:

- Impairment of contracted concessional, PP&E and other intangible assets.

- Recoverability of deferred tax assets.

- Fair value of derivative financial instruments

- Fair value of identifiable assets and liabilities arising from a business combination

Judgement:

- Assessment of assets agreements.

- Assessment of control.

As of the date of preparation of these Consolidated Condensed Interim Financial Statements, no relevant changes in estimates made are anticipated and, therefore, no significant changes in the value of assets and liabilities recognized at September 30, 2023, are expected.

Although these estimates and assumptions are being made using all available facts and circumstances, it is possible that future events may require management to amend such estimates and assumptions in future periods. Changes in accounting estimates are recognized prospectively, in accordance with IAS 8, in the consolidated income statement of the period in which the change occurs.

Financial risk management

Note 3. - Financial risk management

Atlantica’s activities are exposed to various financial risks: market risk (including currency risk and interest rate risk), credit risk and liquidity risk. Risk is managed by the Company’s Risk Management and Finance Departments, which are responsible for identifying and evaluating financial risks, quantifying them by project, region and company, in accordance with mandatory internal management rules. The internal management rules provide written policies for the management of overall risk, as well as for specific areas. The internal management policies of the Company also define the use of hedging instruments and derivatives and the investment of excess cash.

These Consolidated Condensed Interim Financial Statements do not include all financial risk management information and disclosures required for annual financial statements and should be read together with the information included in Note 3 to Atlantica’s annual consolidated financial statements as of December 31, 2022 included in the 2022 20-F.

Financial information by segment [Abstract]

Financial information by segment

Note 4. - Financial information by segment

Atlantica’s segment structure reflects how management currently makes financial decisions and allocates resources. Its operating and reportable segments are based on the following geographies where the contracted concessional assets are located: North America, South America and EMEA. In addition, based on the type of business, as of September 30, 2023, the Company had the following business sectors: Renewable energy, Efficient natural gas and Heat, Transmission lines and Water.

Atlantica’s Chief Operating Decision Maker (CODM), which is the CEO, assesses the performance and assignment of resources according to the identified operating segments. The CODM considers the revenue as a measure of the business activity and the Adjusted EBITDA as a measure of the performance of each segment. Adjusted EBITDA is calculated as profit/(loss) for the period attributable to the parent company, after adding back loss/(profit) attributable to non-controlling interests, income tax expense, financial expense (net), depreciation, amortization and impairment charges of entities included in the these Consolidated Condensed Interim Financial Statements and depreciation and amortization, financial expense and income tax expense of unconsolidated affiliates (pro rata of Atlantica’s equity ownership).

In order to assess performance of the business, the CODM receives reports of each reportable segment using revenue and Adjusted EBITDA. Net interest expense evolution is assessed on a consolidated basis. Financial expense and amortization are not taken into consideration by the CODM for the allocation of resources.

In the nine-month period ended September 30, 2023, Atlantica had three customers with revenues representing more than 10% of total revenue, in the renewable energy business sector. In the nine-month period ended September 30, 2022, Atlantica had two customers with revenues representing more than 10% of total revenue, both in the renewable energy business sector.

Note 5. – Business combinations

For the nine-month period ended September 30, 2023

On March 1, 2023, the Company completed the process of transitioning the O&M services for the assets in Spain where Abengoa was still the supplier to an Atlantica’ subsidiary. This acquisition has been accounted for in these Consolidated Condensed Interim Financial Statements in accordance with IFRS 3, Business Combinations. The O&M services are included within the Renewable energy sector and the EMEA geography.

The fair value of assets and liabilities consolidated at the effective acquisition date is shown in the following table:

	Business combinations for the nine-month period ended September 30, 2023
Property, plant and equipment under IAS 16		1,565
Intangible assets under IAS 38		5,645
Inventories		1,646
Other current and non-current liabilities		(6,653	)
Total net assets acquired at fair value		2,203
Asset acquisition – purchase price		(2,203	)
Net result of business combinations		-

The purchase price equals the fair value of the net assets acquired.

The allocation of the purchase price is provisional as of September 30, 2023, and amounts indicated above may be adjusted during the measurement period to reflect new information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the amounts recognized as of September 30, 2023. The measurement period will not exceed one year from the acquisition date.

The amount of revenue contributed by the acquisitions during the nine-month period ended September 30, 2023 to the Consolidated Condensed Interim Financial Statements of the Company is nil, and the amount of loss after tax is $0.4 million. Had the acquisitions been consolidated from January 1, 2023, the consolidated statement of comprehensive income would not have included additional revenue and profit after tax of $1.0 million.

For the year ended December 31, 2022

On January 17, 2022, the Company closed the acquisition of Chile TL4, a 63-mile transmission line and 2 substations in Chile for a total equity investment of $38.4 million. Atlantica has control over Chile TL4 under IFRS 10, Consolidated Financial Statements. The acquisition of Chile TL4 had been accounted for in these Consolidated Condensed Interim Financial Statements in accordance with IFRS 3, Business Combinations. Chile TL4 is included within the Transmission Lines sector and the South America geography.

On April 4, 2022, the Company closed the acquisition of Italy PV 4, a 3.6 MW solar portfolio in Italy for a total equity investment of $3.7 million. Atlantica has control over Italy PV 4 under IFRS 10, Consolidated Financial Statements. The acquisition of Italy PV 4 had been accounted for in these Consolidated Condensed Interim Financial Statements in accordance with IFRS 3, Business Combinations. Italy PV 4 is included within the Renewable energy sector and the EMEA geography.

On September 2, 2022, the Company closed the acquisition of Chile PV 3, a 73 MW solar PV plant through its renewable energy platform in Chile for a total equity investment of $7.7 million. Atlantica has control over Chile PV 3 under IFRS 10, Consolidated Financial Statements. The acquisition of Chile PV 3 had been accounted for in these Consolidated Condensed Interim Financial Statements in accordance with IFRS 3, Business Combinations, showing 65% of non-controlling interests. Chile PV 3 is included within the Renewable energy sector and the South America geography.

The fair value of assets and liabilities consolidated at the effective acquisition date is shown in aggregate on the basis that they are individually not significant in the following table:

	Business combinations for the year ended December 31, 2022
Property, plant and equipment under IAS 16		55,135
Rights of use under IFRS 16 (lessee) or intangible assets under IAS 38		26,794
Cash and cash equivalents		1,057
Other current assets		8,283
Non-current Project debt		(1,301	)
Current Project debt		(148	)
Other current and non-current liabilities		(25,853	)
Non-controlling interests		(14,300	)
Total net assets acquired at fair value		49,667
Asset acquisition – purchase price		(49,667	)
Net result of business combinations		-

The purchase price equaled the fair value of the net assets acquired.

The amount of revenue contributed by the acquisitions performed during 2022 to the Consolidated Financial Statements of the Company for the year 2022 was $6.2 million, and the amount of profit after tax was $1.7 million. Had the acquisitions been consolidated from January 1, 2022, the consolidated statement of comprehensive income would have included additional revenue of $4.8 million and additional profit after tax of $1.7 million.

In January, April and September 2023, the provisional period for the purchase price allocation of Chile TL 4, Italy PV 4 and Chile PV 3, respectively, closed, and did not result in significant adjustments to the initial amounts recognized.

2007 Vento II, LLC, is the holding company of a 596 MW portfolio of wind assets (“Vento II”) in the U.S., 49% owned by Atlantica since June 16, 2021, and accounted for under the equity method in these Consolidated Condensed Interim Financial Statements.

Windlectric Inc., the project entity, is 100% owned by Amherst Island Partnership, itself 30% owned by Atlantica Yield Energy Solutions Canada Inc. (“AYES Canada”) and therefore accounted for under the equity method in these Consolidated Condensed Interim Financial Statements.

Myah Bahr Honaine, S.P.A., the project entity, is 51% owned by Geida Tlemcen, S.L., which is accounted for using the equity method in these Consolidated Condensed Interim Financial Statements. Geida Tlemcen, S.L. is 50% owned by Atlantica.

Pemcorp SAPI de CV, Monterrey´s project entity, is 100% owned by Arroyo Netherlands II B.V., which is accounted for under the equity method in these Consolidated Condensed Interim Financial Statements. Arroyo Netherlands II B.V. is 30% owned by Atlantica.

Akuo Atlantica PMGD Holding S.P.A.(“Akuo”) is the holding company of an 80 MW portfolio of solar PV assets in Chile, which is currently under construction, 49% owned by Atlantica, with joint control since November 2022 and accounted for under the equity method in these Consolidated Condensed Interim Financial Statements.

The Colombian portfolio of renewable energy entities includes the following entities: Atlantica – HIC Renovables S.A.S., SJ Renovables Sun 1 S.A.S. E.S, AC Renovables Sol 1 S.A.S. E.S, SJ Renovables Wind 1 S.A.S. E., PA Renovables Sol 1 S.A.S. E.S and Atlantica Hidro Colombia S.A.S. On March 1, 2023, Atlantica sold part of its equity interest in these entities to a partner, which now holds a 50% equity interest. Atlantica and the partner hold 50% of the shares each and have joint control over these entities in accordance with IFRS 11, Joint arrangements. As a result, the subsidiaries, which were previously fully consolidated showing 30% of non-controlling interest, are now recorded as an investment in joint ventures under the equity method in these Consolidated Condensed Interim Financial Statements in accordance with IAS 28, Investments in associates and joint ventures. Carrying amount of the non-controlling interests in these entities were derecognized at the date control was lost by Atlantica. Further to the sale of part of its equity interest, Atlantica recorded a gain of $4.6 million as Other operating income in the nine-month period ended September 30, 2023 (Note 20).

The decrease in investments carried under the equity method as of September 30, 2023, is primarily due to the distributions made by Amherst Island Partnership to AYES Canada for the period for $11.1 million related to the investment in Windlectric Inc. A significant portion of the distributions received from Amherst are distributed by the Company to its partner in this project (Note 13). The decrease in the investment in Vento II is primarily due to the distributions received from this asset by the Company for $11.0 million, partially offset by the share of profit in Vento II for the nine-month period ended September 30, 2023 for $5.3 million.

Note 9. - Derivative financial instruments

The breakdowns of the fair value amount of the derivative financial instruments as of September 30, 2023, and December 31, 2022, are as follows:

	Balance as of September 30, 2023				Balance as of December 31, 2022

Total		113,548		6,454		97,381		16,847

The derivatives are primarily interest rate cash flow hedges. All are classified as non-current assets or non-current liabilities, as they hedge long-term financing agreements.

The net amount of the fair value of interest rate derivatives designated as cash flow hedges transferred to the consolidated condensed income statement is a profit of $18.0 million for the nine-month period ended September 30, 2023 (loss of $31.5 million for the nine-month period ended September 30, 2022).

The after-tax results accumulated in equity in connection with derivatives designated as cash flow hedges as of September 30, 2023, and December 31, 2022, amount to a profit of $357.5 million and $345.6 million, respectively.

Additionally, the Company has currency options with leading international financial institutions, which guarantee minimum Euro-U.S. dollar exchange rates. The strategy of the Company is to hedge the exchange rate for the net distributions from its European assets after deducting euro-denominated interest payments and euro-denominated general and administrative expenses. Through currency options, the strategy of the Company is to hedge 100% of its euro-denominated net exposure for the next 12 months and 75% of its euro denominated net exposure for the following 12 months, on a rolling basis. Change in fair value of these foreign exchange derivatives instruments are directly recorded in the consolidated income statement.

Finally, the conversion option of the Green Exchangeable Notes issued in July 2020 (Note 14) is recorded as a derivative with a fair value (liability) of $0.9 million as of September 30, 2023 ($4.7 million as of December 31, 2022).

Fair value of financial instruments

Note 10. - Fair value of financial instruments

Financial instruments measured at fair value are classified based on the nature of the inputs used for the calculation of fair value:

- Level 1: Inputs are quoted prices in active markets for identical assets or liabilities.

- Level 2: Fair value is measured based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices).

- Level 3: Fair value is measured based on unobservable inputs for the asset or liability.

As of September 30, 2023, all the financial instruments measured at fair value correspond to derivatives and have been classified as Level 2, except for the investments held in Ten West Link, which has been classified as Level 3.

Trade and other receivables

Note 12. - Trade and other receivables

Trade and other receivables as of September 30, 2023, and December 31, 2022, consist of the following:

	Balance as of September 30,		Balance as of December 31,
	2023		2022
	($ in thousands)
Trade receivables		225,144		125,437

Prepayments		23,636		11,827
Other accounts receivable		4,703		17,390
Total		287,202		200,334

The increase in trade receivables is primarily due to collections pending from the Spanish state-owner regulator, Comision Nacional de los Mercados y de la Competencia or “CNMC” in the solar assets of the Company in Spain and from Pemex in ACT.

During the year 2022, in the assets in Spain, the Company collected revenue in line with the parameters corresponding to the regulation in place at the beginning of the year 2022, as the new parameters, reflecting lower revenue, became final on December 14, 2022. As a result, as of December 31, 2022, trade receivables in the assets in Spain were lower than usual. In the nine-month period ended September 30, 2023, collections at these assets in Spain were regularized.

As of September 30, 2023, and December 31, 2022, the fair value of trade and other receivables accounts does not differ significantly from its carrying amount.

Project debt [Abstract]

Project debt

Note 15. - Project debt

This note shows the project debt linked to the assets included in Note 6 of these Consolidated Condensed Interim Financial Statements.

Project debt is generally used to finance contracted assets, exclusively using as guarantee the assets and cash flows of the company or group of companies carrying out the activities financed. In addition, the cash of the Company´s projects include funds held to satisfy the customary requirements of certain non-recourse debt agreements and other restricted cash for an amount of $209 million as of September 30, 2023 ($208 million as of December 31, 2022).

The breakdown of project debt for both non-current and current liabilities as of September 30, 2023, and December 31, 2022, is as follows:

	Balance as of September 30,		Balance as of December 31,
	2023		2022
	($ in thousands)
Non-current		4,012,592		4,226,518
Current		399,472		326,534
Total Project debt		4,412,064		4,553,052

The Company refinanced the Solaben 2&3 assets in March 2023, entering into two green senior euro-denominated loan agreements for the two assets with a syndicate of banks for a total amount of €198.0 million. The new project debt replaced the previous project loans for a similar amount and maturity was extended from December 2030 to June 2037.

Chile PV 1, where the Company owns a 35% equity interest, was not able to maintain the minimum required cash in its debt service reserve account during the third quarter of 2023 due to low electricity prices, which represents an event of default as of September 30, 2023. As a result, although the Company does not expect an acceleration of the debt to be declared by the credit entities, Chile PV 1 did not have an unconditional right to defer the settlement of the debt for at least twelve months and the project debt, which amounts to $49 million as of September 30, 2023, was classified as current in these Consolidated Condensed Interim Financial Statements in accordance with International Accounting Standards 1 (“IAS 1”), “Presentation of Financial Statements”.

The repayment schedule for project debt in accordance with the financing arrangements as of September 30, 2023, is as follows and is consistent with the projected cash flows of the related projects:

Remainder of 2023
Interest payment		Nominal repayment		Between January and September 2024		Between October and December 2024		2025		2026		2027		Subsequent years		Total

The repayment schedule for project debt in accordance with the financing arrangements as of December 31, 2022, was as follows and was consistent with the projected cash flows of the related projects:

2023				2024		2025		2026		2027		Subsequent years		Total

Others		42,283		45,365
Grants and other non-current liabilities		1,236,850		1,252,513

As of September 30, 2023, the amount recorded in Grants primarily corresponds to the ITC Grant awarded by the U.S. Department of the Treasury to Solana and Mojave for a total amount of $586 million ($610 million as of December 31, 2022). The amount recorded in Grants as a liability is progressively recorded as other income over the useful life of the asset.

The remaining balance of the “Grants” account corresponds to loans with interest rates below market rates for Solana and Mojave for a total amount of $280 million as of September 30, 2023 ($299 million as of December 31, 2022). Loans with the Federal Financing Bank guaranteed by the Department of Energy for these projects bear interest at a rate below market rates for these types of projects and terms. The difference between proceeds received from these loans and its fair value, is initially recorded as “Grants” in the consolidated statement of financial position, and subsequently recorded progressively in “Other operating income”.

Total amount of income for these two types of grants for Solana and Mojave is $43.8 million and $43.9 million for the nine-month periods ended September 30, 2023 and 2022, respectively (Note 20).

The “Accruals on Spanish market prices differences” corresponds to the non-current portion of the payables related to the high market prices in Spain at which the solar assets in Spain invoiced electricity up to September 30, 2023, as a result of a negative adjustment to the regulated revenues for the deviation from the estimated market prices used by the Administration in Spain, which is expected to be compensated over the remaining regulatory life of the solar assets of the Company.

Income Tax [Abstract]

Income Tax

Note 18. - Income Tax

The effective tax rate for the periods presented has been established based on management’s best estimates, taking into account the tax treatment of permanent differences and tax credits.

For the nine-month period ended September 30, 2023, income tax amounted to a $11,587 thousand expense with respect to a profit before income tax of $60,483 thousand. In the nine-month period ended September 30, 2022, income tax amounted to a $12,975 thousand expense with respect to a profit before income tax of $14,780 thousand. The effective tax rate differs from the nominal tax rate mainly due to permanent tax differences in some jurisdictions.

Financial income and expense

The following table sets forth financial income and expenses for the nine-month periods ended September 30, 2023 and 2022:

	For the nine-month period ended September 30,
	2023		2022
Financial income	($ in thousands)
Interest income on deposits		15,099		3,812
Interest income from loans and credits		2,046		994

Interest rates gains/(losses) on derivatives: cash flow hedges		17,785			(31,724	)
Total		(243,083	)		(243,208	)

Interest expense on loans and notes primarily include interest on corporate and project debt.

Gains and losses from interest rate derivatives designated as cash flow hedges primarily correspond to transfers from equity to financial expense when the hedged item impacts the consolidated income statement. The decrease of losses and increase of gains in the nine-month period ended September 30, 2023 compared to the nine-month period ended September 30, 2022, is due to an increase in the spot interest rates in 2023 compared to 2022, which implies lower interest payments on the derivatives instruments contracted.

Net exchange differences

Net exchange differences primarily correspond to realized and unrealized exchange gains and losses on transactions in foreign currencies as part of the normal course of business of the Company.

Other financial income and expenses

The following table sets out Other financial income and expenses for the nine-month periods ended September 30, 2023, and 2022:

	For the nine-month period ended September 30,

Other financial losses		(19,847	)		(16,582	)
Total		(12,011	)		(1,456	)

Other financial income in the nine-month period ended September 30, 2023 include an income for non-monetary change to the fair value of derivatives of Kaxu for which hedge accounting is not applied for $1.1 million, and $3.8 million of income further to the change in the fair value of the conversion option of the Green Exchangeable Notes (Note 14) in the period ($6.2 million and $6.8 million of income respectively in the nine-month period ended September 30, 2022).

Other financial losses primarily include guarantees and letters of credit, other bank fees and non-monetary interest expenses for updating the present value of provisions and other long-term liabilities reflecting passage of time.

Other expenses		(13,278	)		(11,220	)
Total		(237,930	)		(261,435	)

The decrease in other operating expenses for the nine-month period ended September 30, 2023 is primarily due to:

-  the internalization of the O&M services in the solar assets in Spain during 2022 and 2023. These services are now provided by employees of Atlantica, whose cost is classified within the line “Employee benefit expense” of the profit and loss statement; and

-  to the lower cost of supplies due to lower price of electricity in the solar assets in Spain in 2023.

Earnings per share

Note 21. - Earnings per share

Basic earnings per share have been calculated by dividing the profit/(loss) attributable to equity holders of the Company by the average number of outstanding shares.

Average number of outstanding diluted shares for the nine-month period ended September 30, 2023 have been calculated considering the potential issuance of 3,347,305 shares (3,347,305 shares for the nine-month period ended September 30, 2022) on the settlement of the Green Exchangeable Notes (Note 14) and the potential issuance of 219,762 shares (224,269 shares for the nine-month period ended September 30, 2022) under the long-term incentive plans granted to employees. It also included the potential issuance of 596,681 shares to Algonquin for the nine-month period ended September 30, 2022 under the agreement signed on August 3, 2021, according to which Algonquin has the option, on a quarterly basis, to subscribe such number of shares to maintain its percentage in Atlantica in relation to the use of the ATM program (Note 13).

Basis of preparation [Abstract]

Basis of preparation

The accompanying Consolidated Condensed Interim Financial Statements represent the consolidated results of the Company and its subsidiaries.

The Company’s annual consolidated financial statements as of December 31, 2022, were approved by the Board of Directors on February 28, 2023.

These Consolidated Condensed Interim Financial Statements are presented in accordance with International Accounting Standards (“IAS”) 34, “Interim Financial Reporting”. In accordance with IAS 34, interim financial information is prepared solely in order to update the most recent annual consolidated financial statements prepared by the Company, placing emphasis on new activities, occurrences and circumstances that have taken place during the nine-month period ended September 30, 2023, and not duplicating the information previously published in the annual consolidated financial statements for the year ended December 31, 2022. Therefore, the Consolidated Condensed Interim Financial Statements do not include all the information that would be required in a complete set of consolidated financial statements prepared in accordance with the IFRS-IASB (“International Financial Reporting Standards-International Accounting Standards Board”). In view of the above, for an adequate understanding of the information, these Consolidated Condensed Interim Financial Statements must be read together with Atlantica’s consolidated financial statements for the year ended December 31, 2022 included in the 2022 20-F.

In determining the information to be disclosed in the notes to the Consolidated Condensed Interim Financial Statements, Atlantica, in accordance with IAS 34, has taken into account its materiality in relation to the Consolidated Condensed Interim Financial Statements.

The Consolidated Condensed Interim Financial Statements are presented in U.S. dollars, which is the parent company’s functional and presentation currency. Amounts included in these Consolidated Condensed Interim Financial Statements are all expressed in thousands of U.S. dollars, unless otherwise indicated.

These Consolidated Condensed Interim Financial Statements were approved by the Board of Directors of the Company on November 7, 2023.

Application of new accounting standards

Application of new accounting standards

a) Standards, interpretations and amendments effective from January 1, 2023, under IFRS-IASB, applied by the Company in the preparation of these Consolidated Condensed Interim Financial Statements:

The applications of these amendments have not had any impact on these Consolidated Condensed Interim Financial Statements.

In addition, the IASB published in May 2023 an amendment to IAS 12, “Income taxes”, to clarify the application of this standard arising from tax legislation enacted or substantively enacted in each country to implement the Pillar Two model rules in which it provides:

- a temporary exception to the accounting for deferred taxes in connection with the implementation of Pillar Two.

- qualitative and quantitative disclosures to enable users to understand the entities’ exposure to taxes that may arise from the Pillar Two model rules and/or the entity’s progress in its implementation.

The Company is currently working on analyzing the implications arising from this new regulation applicable for accounting periods commencing on or after December 31, 2023.

b) Standards, interpretations and amendments published by the IASB that will be effective for periods beginning on or after January 1, 2024:

The Company does not anticipate any significant impact on the Consolidated Condensed Interim Financial Statements derived from the application of the new standards and amendments that will be effective for annual periods beginning on or after January 1, 2024, although it is currently still in the process of evaluating such application.

The Company has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

Use of estimates

Use of estimates

Some of the accounting policies applied require the application of significant judgment by management to select the appropriate assumptions to determine these estimates. These assumptions and estimates are based on the Company´s historical experience, advice from experienced consultants, forecasts and other circumstances and expectations as of the close of the financial period. The assessment is considered in relation to the global economic situation of the industries and regions where the Company operates, taking into account future development of its businesses. By their nature, these judgments are subject to an inherent degree of uncertainty; therefore, actual results could materially differ from the estimates and assumptions used. In such cases, the carrying values of assets and liabilities are adjusted.

The most critical accounting policies, which require significant management estimates and judgment are as follows:

Estimates:

- Impairment of contracted concessional, PP&E and other intangible assets.

- Recoverability of deferred tax assets.

- Fair value of derivative financial instruments

- Fair value of identifiable assets and liabilities arising from a business combination

Judgement:

- Assessment of assets agreements.

- Assessment of control.

As of the date of preparation of these Consolidated Condensed Interim Financial Statements, no relevant changes in estimates made are anticipated and, therefore, no significant changes in the value of assets and liabilities recognized at September 30, 2023, are expected.

Although these estimates and assumptions are being made using all available facts and circumstances, it is possible that future events may require management to amend such estimates and assumptions in future periods. Changes in accounting estimates are recognized prospectively, in accordance with IAS 8, in the consolidated income statement of the period in which the change occurs.

Fair value of financial instruments (Policies)

9 Months Ended

Sep. 30, 2023

Fair value of financial instruments [Abstract]

Fair value of financial instruments

Financial instruments measured at fair value are classified based on the nature of the inputs used for the calculation of fair value:

- Level 1: Inputs are quoted prices in active markets for identical assets or liabilities.

- Level 2: Fair value is measured based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices).

- Level 3: Fair value is measured based on unobservable inputs for the asset or liability.

As of September 30, 2023, all the financial instruments measured at fair value correspond to derivatives and have been classified as Level 2, except for the investments held in Ten West Link, which has been classified as Level 3.

It also included the potential issuance of 596,681 shares to Algonquin for the nine-month period ended September 30, 2022 under the agreement signed on August 3, 2021, according to which Algonquin has the option, on a quarterly basis, to subscribe such number of shares to maintain its percentage in Atlantica in relation to the use of the ATM program (Note 13).
