The project financing arrangement for Kaxu contained a cross-default provision related to Abengoa S.A.’s insolvency filing. In September 2021, the Company obtained a waiver for such cross-default which became effective on March 31, 2022, following the transfer of the employees performing the O&M in Kaxu from an Abengoa subsidiary to an Atlantica subsidiary and other conditions. As a result, as of March 31, 2022, the Company had again an unconditional right to defer the settlement of the debt for at least twelve months, and therefore the debt previously presented as current (as of December 31, 2021) had been reclassified as non-current at that date in accordance with the financing agreements in these Consolidated Financial Statements (Note 15). As expected in 2022, the Administration in Spain approved, measures to adjust the regulated revenue component for renewable energy plants, following the increase since mid-2021 in the billings of these plants for the sale of electricity in the market. On March 30, 2022, Royal Decree Law 6/2022 was published, adopting urgent measures in response to the economic and social consequences of the war in Ukraine. This Royal Decree Law contains a bundle of measures in diverse fields, including those targeted at containing the sharp rise in gas and electricity prices. It includes temporary changes to the detailed regulated components of revenue received by the solar assets of the Company in Spain, which are applicable from January 1, 2022. Specifically, prior to the entry into force of this new regulation, the level of remuneration under that specific remuneration system depended on the market price estimates used to calculate it, which are revised in each regulatory semi-period. Now, under article 5 of Royal Decree Law 6/2022, an extraordinary measure has been taken to subdivide the current regulatory semi-period, so as to create a new semi-period between January 1, 2022 and December 31, 2022 and the remuneration will be reviewed taking into account the future prices of OMIP (Regulated market operator in Spain), too. On May 14, 2022, the Royal Decree Law 10/2022 was published, including the so-called “Iberian mechanism”, which is the temporary production cost adjustment mechanism for reducing the price of electricity in the wholesale market. The main changes included by these regulations are - The statutory half-period of three years from 2020 to 2022 has been split into two statutory half-periods (1) from January 1, 2020 until December 31 2021 and (2) calendar year 2022. As a result, the fixed monthly payment based on installed capacity (Remuneration on Investment or Rinv) for calendar year 2022 has been revised in the new Order TED/1232/2022. - The electricity market price assumed by the regulation for calendar year 2022 was changed from €48.82 per MWh to an expected price of €121.9 per MWh, i.e., the remuneration parameters of 2022 have been updated with real prices of 2020 (33.94 €/MWh) and 2021 (111.90 €/MWh) and the future prices of OMIP for 2022 (value of second semester 2021: 121.9 €/MWh). As a result, the variable payment based on net electricity produced (Remuneration on Operation or Ro), is also being adjusted. The proposed Ro for the year 2022 is zero €/MWh reflecting the fact that market prices for the power sold in the market are significantly higher. Following the mandate contained in Royal Decree Law 6/2022 and Royal Decree Law 10/2022, whose main measures have been exposed above, the remuneration parameters have been updated for the year 2022 by the recent Order TED/1232/2022, of December 2, 2022, that was published in final form on December 14, 2022. For the three-year semi period starting on January 1, 2023, and ending on December 31, 2025, the adjustment for electricity price deviations in the preceding statutory half period will be progressively modified to take into account a mix of actual market prices and future market prices. On December 28, 2022 the proposed parameters for the year 2023 were published. They are still subject to review. All the adjustments to the regulated revenue of the solar assets of the Company in Spain stated above do not affect the reasonable return on investment previously set by the Spanish government, and therefore do not impact the value of these assets in the long term. The Consolidated Financial Statements were approved by the Board of Directors of the Company on February 28, 2023.

Significant accounting policies [Abstract]
Significant accounting policies	Note 2.- Significant accounting policies 2.1 Basis of preparation These Consolidated Financial Statements are presented in accordance with the International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The Consolidated Financial Statements are presented in U.S. dollars, which is the Company’s functional and presentation currency. Amounts included in these Consolidated Financial Statements are all expressed in thousands of U.S. dollars, unless otherwise indicated. The Company presents assets and liabilities in the statement of financial position based on current/non-current classification. An asset or liability is current when it is expected or due to be realized within twelve months after the reporting period. The Company recognises that there may be potential financial implications in the future from changes in legislation and regulation implemented to address climate change risk. Over time these changes may have an impact across a number of areas of accounting. However, as at the reporting sheet date, the Company believes there is no material impact on the balance sheet carrying values of assets or liabilities. Application of new accounting standards a) Standards, interpretations and amendments effective from January 1, 2022 under IFRS-IASB, applied by the Company in the preparation of these Consolidated Financial Statements: The applications of these amendments have not had any impact on these financial statements. b) Standards, interpretations and amendments published by the IASB that will be effective for periods beginning on or after January 1, 2023: The Company does not anticipate any significant impact on the Consolidated 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, 2023, 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. 2.2. Principles to include and record companies in the consolidated financial statements Companies included in these Consolidated Financial Statements are accounted for as subsidiaries as long as Atlantica has control over them and are accounted for as investments under the equity method as long as Atlantica has significant influence over them, in the periods presented. a) Controlled entities Control is achieved when the Company: ● Has power over the investee; ● Is exposed, or has rights, to variable returns from its involvement with the investee; and ● Has the ability to use its power to affect its returns. The Company reassesses whether or not it controls an investee when facts and circumstances indicate that there are changes to one or more of the three elements of control listed above. The Company uses the acquisition method to account for business combinations of companies previously controlled by a third party. According to this method, identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. Any contingent consideration is recognized at fair value at the acquisition date and subsequent changes in its fair value are recognized in accordance with IFRS 9 in profit or loss. Acquisition related costs are expensed as incurred. The Company recognizes any non-controlling interest in the acquiree either at fair value or at the non-controlling interest’s proportionate share of the acquirer’s net assets on an acquisition by acquisition basis. All assets and liabilities between entities of the group, equity, income, expenses, and cash flows relating to transactions between entities of the group are eliminated in full. b) Investments accounted for under the equity method An associate is an entity over which the Company has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies. A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control. The results and assets and liabilities of associates and joint ventures are incorporated in these financial statements using the equity method of accounting. Under the equity method, an investment in an associate or joint venture is initially recognized in the statement of financial position at fair value and adjusted thereafter to recognize changes in Atlantica´s share of net assets of the associate or joint venture since the acquisition date. Any goodwill relating to the associate or joint venture is included in the carrying amount of the investment and is not tested for impairment separately. Controlled entities, associates and joint ventures included in these financial statements as of December 31, 2022 and 2021 are set out in appendices. 2.3. Contracted concessional, Property, Plant and Equipment (PP&E) and other intangible The assets accounted for by the Company as contracted concessional assets under IFRIC 12 (either intangible model or financial model), as PP&E under IAS 16 or as other intangible assets under IAS 38 or under IFRS 16 (as “Lessee” or “Lessor”), include renewable energy assets, transmission lines, efficient natural gas assets and water plants. a) Contracted concessional assets under IFRIC 12 The infrastructure used in a concession accounted for under IFRIC 12 can be classified as an intangible asset or a financial asset, depending on the nature of the payment entitlements established in the agreement. The application of IFRIC 12 requires extensive judgement in relation to, among other factors, (i) the identification of certain infrastructures and contractual agreements in the scope of IFRIC 12, (ii) an understanding of the nature of the payments in order to determine the classification of the infrastructure as a financial asset or as an intangible asset and (iii) the timing and recognition of revenue from construction and concessionary activity. Under the terms of contractual arrangements within the scope of this interpretation, the operator shall recognize and measure revenue in accordance with IFRS 15 for the services it performs. The useful life of these assets is approximately the same as the length of the concession arrangement. Intangible assets The Company recognizes an intangible asset to the extent that it receives a right to charge final customers for the use of the infrastructure. This intangible asset is subject to the provisions of IAS 38 and is amortized linearly, taking into account the estimated period of commercial operation of the infrastructure which coincides with the concession period. Once the infrastructure is in operation, the treatment of income and expense is as follows: - Revenues from the updated annual revenue for the contracted concession, as well as revenues from operations and maintenance services are recognized in each period according to IFRS 15 “Revenue from contracts with Customers”. - Operating and maintenance costs and general overheads and administrative costs are recorded in accordance with the nature of the cost incurred (amount due) in each period. Financial asset The Company recognizes a financial asset when demand risk is assumed by the grantor, to the extent that the concession holder has an unconditional right to receive payments for the asset. This asset is recognized at the fair value of the construction services provided, considering upgrade services in accordance with IFRS 15, if any. The financial asset is subsequently recorded at amortized cost calculated according to the effective interest method, using a theoretical internal return rate specific to the asset. Revenue from operations and maintenance services is recognized in each period according to IFRS 15 “Revenue from contracts with Customers”. Allowance for expected credit losses (financial assets) According to IFRS 9, Atlantica recognizes an allowance for expected credit losses (ECLs) for all debt instruments not held at fair value through profit or loss. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Company expects to receive. There are two main approaches to applying the ECL model according to IFRS 9: the general approach which involves a three stage approach, and the simplified approach, which can be applied to trade receivables, contract assets and lease receivables. Atlantica applies the simplified approach. Under this approach, there is no need to monitor for significant increases in credit risk and entities will be required to measure lifetime expected credit losses at the end of each reporting period. The key elements of the ECL calculations, based on external sources of information, are the following: - the Probability of Default (“PD”) is an estimate of the likelihood of default over a given time horizon. Atlantica calculates PD based on Credit Default Swaps spreads (“CDS”); - the Exposure at Default (“EAD”) is an estimate of the exposure at a future default date; - the Loss Given Default (“LGD”) is an estimate of the loss arising in the case where a default occurs at a given time. It is based on the difference between the contractual cash flows due and those that the Company would expect to receive. It is expressed as a percentage of the EAD. b) Property, plant and equipment under IAS 16 Property, plant and equipment is measured at historical cost, including all expenses directly attributable to the acquisition, less depreciation and impairment losses, with the exception of land, which is presented net of any impairment losses. Such cost includes the cost of replacing part of the plant and equipment and borrowing costs for long-term installation projects if the recognition criteria are met. Repair and maintenance costs are recognized in profit or loss as incurred. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets. The Company reviews the estimated residual values and expected useful lives of assets at least annually. In particular, the Company considers the impact of health, safety and environmental legislation in its assessment of expected useful lives and estimated residual values. An item of property, plant and equipment and any significant part initially recognized is derecognized upon disposal (i.e., at the date the recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the statement of profit or loss when the asset is derecognized. c) Rights of use under IFRS 16 The Company assesses at contract inception whether a contract is, or contains, a lease. That is, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Company as a lessee: The Company applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value assets. The Company recognizes lease liabilities to make lease payments and right-of-use assets representing the right to use the underlying assets. Main right of use agreements correspond to land rights. The Company recognizes right-of-use assets at the commencement date of the lease (i.e. the date the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities (Note 2.11). The cost of right-of-use assets includes the amount of lease liabilities recognised, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received. Right-of-use assets are depreciated on a straight-line basis over the shorter of the lease term and the estimated useful lives of the assets. d) Other intangible assets Other intangible assets acquired separately are measured on initial recognition at cost. The cost of intangible assets acquired in a business combination is their fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. Intangible assets are amortized over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. An intangible asset is derecognised upon disposal (i.e., at the date the recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising upon derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the statement of profit or loss. Research and development costs: Research costs are expensed as incurred. Development expenditures on an individual project are recognised as an intangible asset when the Company can demonstrate: - the technical feasibility of completing the intangible asset so that the asset will be available for use or sale - its intention to complete and its ability and intention to use or sell the asset - how the asset will generate future economic benefits - the availability of resources to complete the asset - the ability to measure reliably the expenditure during development. Following initial recognition of the development expenditure as an asset, the asset is carried at cost less any accumulated amortization and accumulated impairment losses. Amortization of the asset begins when development is complete, and the asset is available for use. It is amortized over the period of expected future benefit. During the period of development, the asset is tested for impairment annually. e) Asset impairment Atlantica reviews its contracted concessional assets to identify any indicators of impairment at least annually, except for ECL assessment for financial assets which is discussed above. When impairment indicators exist, the Company calculates the recoverable amount of the asset. The recoverable amount of an asset is the higher of its fair value less costs to sell and its value in use, defined as the present value of the estimated future cash flows to be generated by the asset. In the event that the asset does not generate cash flows independently of other assets, the Company calculates the recoverable amount of the Cash Generating Unit (‘CGU’) to which the asset belongs. When the carrying amount of the CGU to which these assets belong is higher than its recoverable amount, the assets are impaired. Assumptions used to calculate value in use include a discount rate and projections considering real data based in the contracts terms and projected changes in both selling prices and costs. The discount rate is estimated by Management, to reflect both changes in the value of money over time and the risks associated with the specific CGU. For contracted concessional assets, with a defined useful life and with a specific financial structure, cash flow projections until the end of the project are considered and no relevant terminal value is assumed. Contracted concessional assets have a contractual structure that permits the Company to estimate quite accurately the costs of the project and revenue during the life of the project. Projections take into account real data based on the contract terms and fundamental assumptions based on specific reports prepared internally and third-party reports, assumptions on demand and assumptions on production. Additionally, assumptions on macro-economic conditions are taken into account, such as inflation rates, future interest rates, etc. and sensitivity analyses are performed over all major assumptions which can have a significant impact in the value of the asset. Cash flow projections of CGUs are calculated in the functional currency of those CGUs and are discounted using rates that take into consideration the risk corresponding to each specific country and currency. Taking into account that in most CGUs the specific financial structure is linked to the financial structure of the projects that are part of those CGUs, the discount rate used to calculate the present value of cash-flow projections is based on the weighted average cost of capital (WACC) for the type of asset, adjusted, if necessary, in accordance with the business of the specific activity and with the risk associated with the country where the project is performed. In any case, sensitivity analyses are performed, especially in relation to the discount rate used and fair value changes in the main business variables, in order to ensure that possible changes in the estimates of these items do not impact the recovery of recognized assets. In the event that the recoverable amount of an asset is lower than its carrying amount, an impairment charge for the difference would be recorded in the income statement under the item “Depreciation, amortization and impairment charges”. An assessment is made at each reporting date to determine whether there is an indication that previously recognized impairment losses no longer exist or have decreased. If such indication exists, the Company estimates the CGU’s recoverable amount. A previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the asset’s recoverable amount since the last impairment loss was recognized. The reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount, nor exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in the income statement. 2.4. R evenue recognition According to IFRS 15, Revenue from Contracts with Customers, the Company assesses the goods and services promised in the contracts with the customers and identifies as a performance obligation each promise to transfer to the customer a good or service (or a bundle of goods or services). In the case of contracts related to intangible or financial assets under IFRIC 12, the performance obligation of the Company is the operation of the asset. The contracts between the parties set the price of the service in an orderly transaction and therefore corresponds to the fair value of the service provided. The service is satisfied over time. The same conclusion applies to concessional assets that are classified as tangible assets under IAS 16 or leases under IFRS 16. All of the transaction prices of assets under IFRIC 12 are fixed and included as part of the long-term PPAs of the Company as disclosed in Appendix III-2. In the case of financial asset under IFRIC 12, the financial asset accounts for the payments to be received from the client over the residual life of the contract, discounted at a theoretical internal rate of return for the project. In each period, the financial asset is reduced by the amounts received from the client and increased by any capital expenditure that the project may incur and by the effect of unwinding the discount of the financial asset at the theoretical internal rate of return. The increase of the financial asset deriving from the unwinding of the discount of the financial asset is recorded as revenue in each period. Revenue will therefore differ from the actual billings made to the client in each period. In the case of Spain, according to Royal Decree 413/2014, solar electricity producers receive: (i) the market price for the power they produce, (ii) a payment based on the standard investment cost for each type of plant (without any relation whatsoever to the amount of power they generate) and (iii) an “operating payment” (in €/MWh produced). The principle driving this economic regime is that the payments received by a renewable energy producer should be equivalent to the costs that they are unable to recover on the electricity pool market where they compete with non-renewable technologies. This economic regime seeks to allow a “well-run and efficient enterprise” to recover the costs of building and running a plant, plus a reasonable return on investment (project investment rate of return). Some of the Company´s assets in Spain are receiving a remuneration based on a 7.09% reasonable rate of return until December 31, 2025 while others are receiving a remuneration based on a 7.398% reasonable rate of return until December 31, 2031. 2.5. Loans and accounts receivable Loans and accounts receivable are non-derivative financial assets with fixed or determinable payments, not listed on an active market. In accordance with IFRIC 12, certain assets under concessions qualify as financial assets and are recorded as is described in Note 2.3. Pursuant to IFRS 9, an impairment loss is recognized if the carrying amount of these assets exceeds the present value of future cash flows discounted at the initial effective interest rate. Loans and accounts receivable are initially recognized at fair value plus transaction costs and are subsequently measured at amortized cost in accordance with the effective interest rate method. Interest calculated using the effective interest rate method is recognized under other financial income within financial income. 2.6. Derivative financial instruments and hedging activities Derivatives are recognized at fair value in the statement of financial position. The Company maintains both derivatives designated as hedging instruments in hedging relationships, and derivatives to which hedge accounting is not applied. When hedge accounting is applied, hedging strategy and risk management objectives are documented at inception, as well as the relationship between hedging instruments and hedged items. Effectiveness of the hedging relationship needs to be assessed on an ongoing basis. Effectiveness tests are performed prospectively at inception and at each reporting date. The Company analyses on each date if all these requirements are met: - there is an economic relationship between the hedged item and the hedging instrument; - the effect of credit risk does not dominate the value changes that result from that economic relationship; and - the hedge ratio of the hedging relationship is the same as that resulting from the quantity of the hedged item that the Company actually hedges and the quantity of the hedging instrument that the Company uses to hedge that quantity of hedged item. Ineffectiveness is measured following the accumulated dollar offset method. In all cases, current Company´s hedging relationships are considered cash flow hedges. Under this model, the effective portion of changes in fair value of derivatives designated as cash flow hedges are recorded temporarily in equity and are subsequently reclassified from equity to profit or loss in the same period or periods during which the hedged item affects profit or loss. Any ineffective portion of the hedged transaction is recorded in the consolidated income statement as it occurs. When interest rate options are designated as hedging instruments, the time value is excluded from the hedging instrument as permitted by IFRS 9. Changes in the effective portion of the intrinsic are recorded in equity and subsequently reclassified from equity to profit or loss in the same period or periods during which the hedged item affects profit or loss. Any ineffectiveness is recorded as financial income or expense as it occurs. Changes in options time value is recorded as cost of hedging. More precisely, considering that the hedged items are, in all cases, time period hedged item, changes in time value is recognized in other comprehensive income to the extent that it relates to the hedged item. The time value at the date of designation of the option as a hedging instrument, to the extent that it relates to the hedged item, is amortized on a systematic and rational basis over the period during which the hedge adjustment for the option’s intrinsic value could affect profit or loss. When the hedging instrument matures or is sold, or when it no longer meets the requirements to apply hedge accounting, accumulated gains and losses recorded in equity remain as such until the forecast transaction is ultimately recognized in the income statement. However, if it becomes unlikely that the forecast transaction will actually take place, the accumulated gains and losses in equity are recognized immediately in the income statement. Any change in fair value of derivatives instruments to which hedge accounting is not applied is directly recorded in the income statement. 2.7. Fair value estimates Financial instruments measured at fair value are presented in accordance with the following level classification 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. In the event that prices cannot be observed, management shall make its best estimate of the price that the market would otherwise establish based on proprietary internal models which, in the majority of cases, use data based on observable market parameters as significant inputs (Level 2) but occasionally use market data that is not observed as significant inputs (Level 3). Different techniques can be used to make this estimate, including extrapolation of observable market data. The best indication of the initial fair value of a financial instrument is the price of the transaction, except when the value of the instrument can be obtained from other transactions carried out in the market with the same or similar instruments, or valued using a valuation technique in which the variables used only include observable market data, mainly interest rates. Differences between the transaction price and the fair value based on valuation techniques that use data that is not observed in the market, are not initially recognized in the income statement. Atlantica derivatives correspond primarily to the interest rate swaps designated as cash flow hedges, which are classified as Level 2. Description of the valuation method Interest rate swap valuations consist in valuing separately the swap part of the contract and the credit risk. The methodology used by the market and applied by Atlantica to value interest rate swaps is to discount the expected future cash flows according to the parameters of the contract. Variable interest rates, which are needed to estimate future cash flows, are calculated using the curve for the corresponding currency and extracting the implicit rates for each of the reference dates in the contract. These estimated flows are discounted with the swap zero curve for the reference period of the contract. The effect of the credit risk on the valuation of the interest rate swaps depends on the future settlement. If the settlement is favorable for the Company, the counterparty credit spread will be incorporated to quantify the probability of default at maturity. If the expected settlement is negative for the Company, its own credit risk will be applied to the final settlement. Classic models for valuing interest rate swaps use deterministic valuation of the future of variable rates, based on future outlooks. When quantifying credit risk, this model is limited by considering only the risk for the current paying party, ignoring the fact that the derivative could change sign at maturity. A payer and receiver swaption model is proposed for these cases. This enables the associated risk in each swap position to be reflected. Thus, the model shows each agent’s exposure, on each payment date, as the value of entering into the ‘tail’ of the swap, i.e. the live part of the swap. Variables (Inputs) Interest rate derivative valuation models use the corresponding interest rate curves for the relevant currency and underlying reference in order to estimate the future cash flows and to discount them. Market prices for deposits, futures contracts and interest rate swaps are used to construct these curves. Interest rate options (caps and floors) also use the volatility of the reference interest rate curve. To estimate the credit risk of the counterparty, the credit default swap (CDS) spreads curve is obtained in the market for important individual issuers. For less liquid issuers, the spreads curve is estimated using comparable CDSs or based on the country curve. To estimate proprietary credit risk, prices of debt issues in the market and CDSs for the sector and geographic location are used. The fair value of the financial instruments that results from the aforementioned internal models takes into account, among other factors, the terms and conditions of the contracts and observable market data, such as interest rates, credit risk and volatility. The valuation models do not include significant levels of subjectivity, since these methodologies can be adjusted and calibrated, as appropriate, using the internal calculation of fair value and subsequently compared to the corresponding actively traded price. However, valuation adjustments may be necessary when the listed market prices are not available for comparison purposes. 2.8. Trade and other receivables Trade and other receivables are amounts due from customers for sales in the normal course of business. They are recognized initially at fair value and subsequently measured at amortized cost using the effective interest rate method, less allowance for doubtful accounts. Trade receivables due in less than one year are carried at their face value at both initial recognition and subsequent measurement, provided that the effect of not discounting flows is not significant. An allowance for doubtful accounts is recorded when there is objective evidence that the Company will not be able to recover all amounts due as per the original terms of the receivables. The Company has established a provision matrix that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment. 2.9. Cash and cash equivalents Cash and cash equivalents include cash in hand, cash in bank and other highly-liquid current investments with an original maturity of three months or less which are held for the purpose of meeting short-term cash commitments. 2.10. Grants Grants are recognized at fair value when it is considered that there is a reasonable assurance that the grant will be received and that the necessary qualifying conditions, as agreed with the entity assigning the grant, will be adequately complied with. Grants are recorded as liabilities in the consolidated statement of financial position and are recognized in “Other operating income” in the consolidated income statement based on the period necessary to match them with the costs they intend to compensate. In addition, as described in Note 2.11 below, grants correspond also to loans with interest rates below market rates, for the initial difference between the fair value of the loan and the proceeds received. 2.11. Loans and borrowings Loans and borrowings are initially recognized at fair value, net of transaction costs incurred. Borrowings are subsequently measured at amortized cost and any difference between the proceeds initially received (net of transaction costs incurred in obtaining such proceeds) and the repayment value is recognized in the consolidated income statement over the duration of the borrowing using the effective interest rate method. In the case of modification of terms of loans and borrowings, the Company determines whether the modification constitutes an exchange or an extinguishment of the debt instrument. In determining whether there is an exchange, the Company evaluates whether the redemption of the old debt and the issuance of new debt were negotiate

Financial risk management [Abstract]
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. a) Market risk The Company is exposed to market risk, such as movement in foreign exchange rates and interest rates. All of these market risks arise in the normal course of business and the Company does not carry out speculative operations. For the purpose of managing these risks, the Company uses a series of interest rate swaps and options, and currency options. None of the derivative contracts signed has an unlimited loss exposure. - Interest rate risk Interest rate risk arises when the Company’s activities are exposed to changes in interest rates, which arises from financial liabilities at variable interest rates. The main interest rate exposure for the Company relates to the variable interest rate with reference to the Libor, Euribor and SOFR. To minimize the interest rate risk, the Company primarily uses interest rate swaps and interest rate options (caps), which, in exchange for a fee, offer protection against an increase in interest rates. The Company does not use derivatives for speculative purposes. As of December 31, 2022, approximately 92% of the Project debt of the Company and approximately 96% of the Corporate debt either has fixed interest rates or has been hedged with swaps or caps. The Revolving Credit Facility of the Company has variable interest rates and is not hedged (Note 14). In connection with the interest rate derivative positions of the Company, the most significant impacts on these Consolidated Financial Statements are derived from the changes in EURIBOR, SOFR and LIBOR, which represent the reference interest rate for most of the debt of the Company. In the event that EURIBOR, SOFR and LIBOR had risen by 25 basis points as of December 31, 2022, with the rest of the variables remaining constant, the effect in the consolidated income statement would have been a loss of $1.3 million (a loss of $2.5 million in 2021 and a loss of $2.9 million in 2020) and a gain in hedging reserves of $18.4 million ($22.4 million in 2021 and $22.1 million in 2020). The gain in hedging reserves would be mainly due to an increase in the fair value of interest rate swaps designated as hedges. A breakdown of the interest rates derivatives as of December 31, 2022 and 2021, is provided in Note 9. - Currency risk The main cash flows in the entities included in these Consolidated Financial Statements are cash collections arising from long-term contracts with clients and debt payments arising from project finance repayment. Given that financing of the projects is typically closed in the same currency in which the contract with client is signed, a natural hedge exists for the main operations of the Company. In addition, to further mitigate this exposure, the Company policy is to contract currency options with leading financial institutions, which guarantee a minimum Euro-U.S. dollar exchange rate on the net distributions expected from solar assets in Europe. The net Euro exposure is 100% hedged for the coming 12 months and 75% for the following 12 months on a rolling basis. Although the Company hedges cash-flows in euros, fluctuations in the value of the euro in relation to the U.S. dollar may affect its 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 the operating results of the Company. Apart from the impact of these translation differences, the exposure of the income statement of the Company 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. b) Credit risk The Company considers that it has a limited credit risk with clients as revenues primarily derive from power purchase agreements with electric utilities and state-owned entities. In addition, the diversification by geography and business sector helps to diversify credit risk exposure by diluting the exposure of the Company to a single client. c) Liquidity risk Atlantica’s liquidity and financing policy is intended to ensure that the Company maintains sufficient funds to meet its financial obligations as they fall due. Project finance borrowing permits the Company to finance the project through project debt and thereby insulate the rest of its assets from such credit exposure. The Company incurs in project-finance debt on a project-by-project basis. The repayment profile of each project is established on the basis of 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 significantly. In addition, the Company maintains a periodic communication with its lenders and regular monitoring of debt covenants and minimum ratios. Corporate and Project debt repayment schedules are disclosed in Note 14 and 15, respectively.

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 December 31, 2022, 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 year 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 these Consolidated 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 year ended December 31, 2022, Atlantica had In the year ended December 31, 2021, a) The following tables show Revenues and Adjusted EBITDA by operating segments and business sectors for the years 2022, 2021 and 2020: Revenue Adjusted EBITDA For the year ended December 31, For the year ended December 31, Geography 2022 2021 2020 2022 2021 2020 North America 405,047 395,775 330,921 309,988 311,803 279,365 South America 166,441 154,985 151,460 126,551 119,547 120,023 EMEA 530,541 660,989 530,879 360,561 393,038 396,735 Total 1,102,029 1,211,749 1,013,260 797,100 824,388 796,123 Revenue Adjusted EBITDA For the year ended December 31, For the year ended December 31, Business sectors 2022 2021 2020 2022 2021 2020 Renewable energy 821,377 928,525 753,089 588,016 602,583 576,285 Efficient natural gas & Heat 113,591 123,692 111,030 84,560 99,935 101,006 Transmission lines 113,273 105,680 106,042 88,010 83,635 87,272 Water 53,788 53,852 43,099 36,514 38,235 31,560 Total 1,102,029 1,211,749 1,013,260 797,100 824,388 796,123 The reconciliation of segment Adjusted EBITDA with the profit/(loss) attributable to the parent company is as follows: For the year ended December 31, 2022 2021 2020 Profit/(loss) attributable to the Company (5,443 ) (30,080 ) 11,968 Profit attributable to non-controlling interests 3,356 19,162 4,906 Income tax expense/(income) (9,689 ) 36,220 24,877 Financial expense, net 310,934 340,892 331,810 Depreciation, amortization, and impairment charges 473,638 439,441 408,604 Depreciation and amortization, financial expense and income tax expense of unconsolidated affiliates (pro rata of Atlantica’s equity ownership) 24,304 18,753 13,958 Total segment Adjusted EBITDA 797,100 824,388 796,123 b) The assets and liabilities by geography and business sector at the end of 2022 and 2021 are as follows: Assets and liabilities by geography as of December 31, 2022: North America South America EMEA Balance as of December 31, 2022 Assets allocated Contracted concessional, PP&E and other intangible assets 3,167,490 1,241,879 3,073,889 7,483,259 Investments carried under the equity method 210,704 4,450 44,878 260,031 Other current financial assets 118,385 31,136 46,373 195,893 Cash and cash equivalents (project companies) 187,568 85,697 266,557 539,822 Subtotal allocated 3,684,147 1,363,162 3,431,697 8,479,005 Unallocated assets Other non-current assets 325,893 Other current assets (including cash and cash equivalents at holding company level) 296,013 Subtotal unallocated 621,906 Total assets 9,100,911 North America South America EMEA Balance as of December 31, 2022 Liabilities allocated Long-term and short-term project debt 1,713,125 841,906 1,998,021 4,553,052 Grants and other liabilities 994,874 25,031 232,608 1,252,513 Subtotal allocated 2,707,999 866,937 2,230,629 5,805,565 Unallocated liabilities Long-term and short-term corporate debt 1,017,200 Other non-current liabilities 313,328 Other current liabilities 175,771 Subtotal unallocated 1,506,299 Total liabilities 7,311,864 Equity unallocated 1,789,047 Total liabilities and equity unallocated 3,295,346 Total liabilities and equity 9,100,911 Assets and liabilities by geography as of December 31, 2021: North America South America EMEA Balance as of December 31, 2021 Assets allocated Contracted concessional, PP&E and other intangible assets 3,355,669 1,231,276 3,434,623 8,021,568 Investments carried under the equity method 253,221 -

Contracted Concessional, PP&E And Other Intangible Assets [Abstract]
Contracted concessional, PP&E and other intangible assets	Note 6.- Contracted concessional, PP&E and other intangible assets The Company has assets recorded as intangible or financial 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. For further details on the application of IFRIC 12 to assets of the Company, see Appendix III. The following table shows the movements of assets included in the heading “Contracted Concessional, PP&E and other intangible assets” for 2022: Cost Financial assets under IFRIC 12 Financial assets under IFRS 16 (Lessor) Intangible assets under IFRIC 12 Right of use assets under IFRS 16 (Lessee) and intangible assets under IAS 38 Property, plant and equipment under IAS 16 Total assets Total as of January 1, 2022 874,525 2,843 9,202,539 100,109 839,119 11,019,135 Additions - - 32,941 4,155 80,196 117,292 Subtractions - (57 ) (499 ) (1,350 ) (8,655 ) (10,561 ) Business combinations (Note 5) - - - 16,993 58,002 74,995 Currency translation differences 1,760 1 (261,536 ) (4,531 ) (21,006 ) (285,312 ) Reclassification and other movements (58,115 ) - 2,798 (6,200 ) 8,950 (52,567 ) Total cost, as of December 31, 2022 818,170 2,787 8,976,243 109,176 956,606 10,862,982 Depreciation, amortization and impairment Financial assets under IFRIC 12 Financial assets under IFRS 16 (Lessor) Intangible assets under IFRIC 12 Right of use assets under IFRS 16 (Lessee) and intangible assets under IAS 38 Property, plant and equipment under IAS 16 Total assets Total as of January 1, 2022 (62,889 ) - (2,769,345 ) (21,578 ) (143,755 ) (2,997,567 ) Additions (6,560 ) - (398,639 ) (6,419 ) (64,306 ) (475,924 ) Subtractions - - - 859 7,643 8,502 Currency translation differences (108 ) - 79,206 822 5,346 85,266 Total depreciation, amortization and impairment, as of December 31, 2022 (69,557 ) - (3,088,778 ) (26,316 ) (195,072 ) (3,379,723 ) Total net book value, as of December 31, 2022 748,613 2,787 5,887,465 82,860 761,534 7,483,259 The decrease in the contracted concessional assets cost is primarily due to the lower value of the Euro denominated assets since the exchange rate of the Euro decreased against the U.S. dollar since December 31, 2021, that more than offsets the increase resulting from business combinations and the additions for the year that primarily correspond to investments in operating concessional assets and assets under development or construction. The increase in accumulated depreciation, amortization and impairment is primarily due to the amortization charge for the year and the impairment registered in Solana, Chile PV1 and Chile PV2 (see further explanation below). The decrease included in “Reclassification and other movement” is mainly due to the reclassification from the long to the short term of the current portion of the contracted concessional financial assets. The following table shows the movements of assets included in the heading “Contracted Concessional, PP&E and other intangible assets” for 2021: Cost Financial assets under IFRIC 12 Financial assets under IFRS 16 (Lessor) Intangible assets under IFRIC 12 Right of use assets under IFRS 16 (Lessee) and intangible assets under IAS 38 Property, plant and equipment under IAS 16 Total assets Total as of January 1, 2021 936,837 2,941 9,467,309 80,030 336,920 10,824,037 Additions 922 442 40,383 3,639 13,024 58,410 Subtractions - - (348 ) (16 ) (21,266 ) (21,630 ) Business combinations (Note 5) - - - 22,149 519,931 542,080 Currency translation differences (9,519 ) (540 ) (334,497 ) (5,693 ) (20,029 ) (370,278 ) Reclassification and other movements (53,715 ) - 29,692 - 10,539 (13,484 ) Total cost, as of December 31, 2021 874,525 2,843 9,202,539 100,109 839,119 11,019,135 Depreciation, amortization and impairment Financial assets under IFRIC 12 Financial assets under IFRS 16 (Lessor) Intangible assets under IFRIC 12 Right of use assets under IFRS 16 (Lessee) and intangible assets under IAS 38 Property, plant and equipment under IAS 16 Total assets Total as of January 1, 2021 (87,689 ) - (2,442,520 ) (16,171 ) (122,239 ) (2,668,619 ) Additions (418 ) - (424,181 ) (6,370 ) (29,392 ) (460,361 ) Reversal of impairment 24,929 - - - - 24,929 Currency translation differences 289 - 97,356 963 7,876 106,484 Total depreciation, amortization and impairment, as of December 31, 2021 (62,889 ) - (2,769,345 ) (21,578 ) (143,755 ) (2,997,567 ) Total net book value, as of December 31, 2021 811,636 2,843 6,433,194 78,531 695,364 8,021,568 The increase in the contracted concessional assets cost was primarily due to business combinations for a total amount of $542 million (Note 5), partially offset by the lower value of the Euro denominated assets since the exchange rate of the Euro decreased against the U.S. dollar since December 31, 2020. This increase was mainly offset by the depreciation and amortization charge for the year and the impairment registered in Solana (see further explanation below). The decrease included in “Reclassification and other movement” was mainly due to the reclassification from the long to the short term of the current portion of the contracted concessional financial assets. Solana triggering event of impairment Considering the continued delays in the works and replacements that the Company is carrying out in the storage system at Solana and their impact on production in 2022, as well as an increase in the discount rate, the Company identified an impairment triggering event, in accordance with IAS 36, Impairment of assets. As a result, an impairment test has been performed using historical level of output (generation), which resulted in the recording of an impairment loss of $41 million in 2022 ($43 million in 2021). The impairment has been recorded within the line “Depreciation, amortization and impairment charges” of the consolidated income statement, decreasing the amount of intangible assets under IFRIC 12 pertaining to the Renewable energy sector and the North America geography. The recoverable amount considered is the value in use and amounts to $881 million for Solana, as of December 31, 2022 ($943 million as of December 31, 2021). A specific discount rate has been used in each year considering changes in the debt/equity leverage ratio over the useful life of this project, resulting in the use of a range of pre-tax discount rates between 5.9% and 6.3% in 2022 (between 4.9% and 5.9% in 2021). An adverse change in the key assumptions which are individually used for the valuation could lead to future impairment recognition; specifically, a 5% decrease in generation over the entire remaining useful life (PPA) of the project would generate an additional impairment of approximately $59 million. An increase of 50 basis points in the discount rate would lead to an additional impairment of approximately $33 million. Chile PV1 and Chile PV2 triggering event of impairment Considering that expected electricity prices in assumed at the time of the acquisition, the Company identified an impairment triggering event, in accordance with IAS 36, Impairment of assets. As a result, an impairment test has been performed which resulted in the recording of an impairment loss of $8 million for Chile PV1 and $12 million for Chile PV2 in 2022. The impairment has been recorded within the line “Depreciation, amortization and impairment charges” of the consolidated income statement, decreasing the amount of Property, plant and equipment under IAS 16 pertaining to the Renewable energy sector and the South America geography. The recoverable amount considered is the value in use and amounts to $58 million for Chile PV1 and $22 million for Chile PV2, as of December 31, 2022. A specific discount rate has been used in each year considering changes in the debt/equity leverage ratio over the useful life of these projects, resulting in the use of a range of pre-tax discount rates between 7.5% and 8.4% for Chile PV1 and 7.5% and 8.3% for Chile PV2 An adverse change in the key assumptions which are individually used for the valuation could lead to future impairment recognition; specifically, a 5% decrease in electricity prices over the entire remaining useful life of these projects would generate an additional total impairment of approximately $5 million. An increase of 50 basis points in the discount rate would lead to an additional total impairment of approximately $3 million. The Company did not identify any other triggering event of impairment of its contracted concessional assets as of December 31, 2022 and 2021. Expected credit losses The impairment provision based on the expected credit losses on contracted concessional financial assets, calculated in accordance with IFRS 9, Financial instruments, increased by $7 million in the year ended December 31, 2022, (decreased by $25 million in the year ended December 31, 2021, primarily in ACT, following an improvement of its client’s credit risk metrics), primarily in ACT.

Investments carried under the equity method	Note 7.- Investments carried under the equity method The table below shows the breakdown and the movement of the investments held in associates and joint ventures for 2022 and 2021: Investments in associates and joint ventures 2022 2021 Initial balance 294,581 116,614 Share of profit 21,465 12,304 Distributions (57,537 ) (36,877 ) Acquisitions 4,901 202,345 Others (incl. currency translation differences) (3,379 ) 195 Final balance 260,031 294,581 In November 2022, Atlantica closed the acquisition of a 49% interest, with joint control, in Chile PMGD, an 80 MW portfolio of solar PV assets in Chile, which is currently starting construction (Note 1). Chile PMGD is accounted for in these Consolidated Financial Statements using the equity method as per IAS 28 – Investments in Associates. The decrease in investments carried under the equity method in 2022, is primarily due to the distributions received by AYES Canada from Amherst Island Partnership for $20.9 million ($17.7 million in 2021), distributions from Vento II for $32.6 million ($14.8 million in 2021) and from Honaine for $4.0 million ($4.4 million in 2021), pa rtially offset by the share of profit of associates for $21.5 million ($12.3 million in 2021) an . A significant portion of the distributions received from Amherst Island Partnership are distributed by the Company to Algonquin Power Co. (Note 13).

Derivative financial instruments	Note 9.- Derivative financial instruments The breakdowns of the fair value amount of the derivative financial instruments as of December 31, 2022 and 2021 are as follows: Balance as of December 31, 2022 Balance as of December 31, 2021 Assets Liabilities Assets Liabilities Interest rate cash flow hedge 94,192 12,159 9,550 206,763 Foreign exchange derivatives instruments 3,189 - 3,410 - Notes conversion option (Note 14) - 4,688 - 16,690 Total 97,381 16,847 12,960 223,453 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. As stated in Note 3 to these Consolidated Financial Statements, the general policy is to hedge variable interest rates of financing agreements using two types of hedging derivatives: - Interest rate swaps under which the Company receives the floating leg and pays the fixed leg; and - Purchased call options (cap), in exchange of a premium to fix the maximum interest rate cost. The notional amounts hedged, strikes contracted and maturities, depending on the characteristics of the debt on which the interest rate risk is being hedged, can be diverse.

The table below shows a breakdown of the maturities of notional amounts of interest rate cash flow hedge derivatives as of December 31, 2022 and 2021.

The after-tax result accumulated in equity in connection with derivatives designated as cash flow hedges at the years ended December 31, 2022 and 2021, amount to a $345,567 thousand gain and a $171,272 thousand gain, 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 $5 million as of December 31, 2022 ($17 million as of December 31, 2021).

The increase of the total remuneration in 2022 is mainly due to the increase of the long-term awards, as a result of the vesting in 2022 of a portion of the share options awarded from 2019 to 2022 and the increase of Atlantica’s share price from the date of such awards being granted. None of the directors received any pension remuneration in 2022 nor 2021.

Each share grants one voting right. Algonquin owns 42.2% of the shares of the Company and is its largest shareholder as of December 31, 2022. Algonquin’s voting rights and rights to appoint directors are limited to 41.5% and the difference between Algonquin´s ownership and 41.5% will vote replicating non-Algonquin’s shareholders’ vote. On December 11, 2020, the Company closed an underwritten public offering of 5,069,200 ordinary shares, including 661,200 ordinary shares sold pursuant to the full exercise of the underwriters’ over-allotment option, at a price of $33 per new share. Gross proceeds were approximately $167 million. Given that the offering was issued through a subsidiary in Jersey, which became wholly owned by the Company at closing, and subsequently liquidated, the premium on issuance was credited to a merger reserve account (Capital reserves), net of issuance costs, for $161 million. Additionally, Algonquin committed to purchase 4,020,860 ordinary shares During the first quarter of 2021, the Company changed the accounting treatment applied to its existing long-term incentive plans granted to employees from cash-settled to equity-settled in accordance with IFRS 2, Share-based Payment, as a result of incentives being settled in shares. The liability recognized for the rights vested by the employees under such plans at the date of this change, was reclassified to equity within the line “Accumulated deficit” for approximately $9 million. The settlement in shares was approved by the Board of Directors on February 26, 2021, and the Company issued 141,482 new shares to its employees up to December 31, 2021, to settle a portion of these plans. During the year 2022, the Company issued 228,560 new shares under such incentive plans. On August 3, 2021, the Company established an “at-the-market program” and entered into a distribution agreement with J.P. Morgan Securities LLC, as sales agent, under which the Company may offer and sell from time to time up to $150 million of its ordinary shares. The Company also entered into an agreement with Algonquin pursuant to which the Company has offered Algonquin the right but not the obligation, on a quarterly basis, to purchase a number of ordinary shares to maintain its percentage interest in Atlantica at the average price of the shares sold under the distribution agreement in the previous quarter (the “ATM Plan Letter Agreement”). On February 28, 2022, the Company established a new “at-the-market program” and entered into a distribution agreement with BofA Securities, MUFG and RBC Capital Markets, as its sales agents, under which the Company may offer and sell from time to time up to $150 million of its ordinary shares. Upon entry into the distribution agreement, the Company terminated its prior “at-the-market program” established on August 3, 2021 and the related distribution agreement dated such date, entered into with J.P. Morgan Securities LLC.

Pursuant to the ATM Plan Letter Agreement, the Company delivers a notice to Algonquin quarterly in order for them to exercise their rights thereunder. Atlantica´s reserves as of December 31, 2022 are made up of share premium account and capital reserves. The share premium account reduction by $200 million during the year 2021, increasing capital reserves by the same amount, was made effective upon the confirmation received from the High Court in the UK, pursuant to the Companies Act 2006. Other reserves primarily include the change in fair value of cash flow hedges and its tax effect. Accumulated currency translation differences primarily include the result of translating the financial statements of subsidiaries prepared in a foreign currency into the presentation currency of the Company, the U.S. dollar. Accumulated deficit primarily includes results attributable to Atlantica.

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 Financial Statements. Project debt is generally used to finance contracted assets, exclusively using as a guarantee the assets and cash flows of the company or group of companies carrying out the activities financed. In most of the cases, the assets and/or contracts are set up as a guarantee to ensure the repayment of the related financing. In addition, the cash of the Company´s projects includes funds held to satisfy the customary requirements of certain non-recourse debt agreements and other restricted cash for an amount of $208 million as of December 31, 2022 ($254 million as of December 31, 2021). The variations in 2022 of project debt have been the following: Project debt - long term Project debt - short term Total Balance as of December 31, 2021 4,387,674 648,519 5,036,193 Increases 39,161 230,320 269,481 Payments (73,478 ) (543,484 ) (616,962 ) Business combinations (Note 5) 1,301 148 1,449 Currency translation differences (119,068 ) (18,041 ) (137,109 ) Reclassifications (9,072 ) 9,072 - Balance as of December 31, 2022 4,226,518 326,534 4,553,052 The decrease in total project debt as of December 31, 2022 is primarily due to: - the repayment of project debt for the period in accordance with the financing arrangements; and - the lower value of debt denominated in Euros given the depreciation of the Euro against the U.S. dollar since December 31, 2021. Interest accrued, which are included in Increases, were offset by a similar amount of interest paid during the year, included in Payments in the table above. As of December 31, 2021, Kaxu total debt was presented as current in the Consolidated Financial Statements of the Company, for an amount of $314 million, in accordance with International Accounting Standards 1 (“IAS 1”), “Presentation of Financial Statements”, as a result of the existence of a theoretical event of default under the Kaxu project finance agreement. Since March 31, 2022, the Company has again an unconditional right to defer the settlement of the debt for at least more than twelve months, and therefore the debt previously presented as current in these Consolidated Financial Statements has been reclassified as non-current in accordance with the financing agreements (Note 1). The variations in 2021 of project debt were the following: Project debt - long term Project debt - short term Total Balance as of December 31, 2020 4,925,268 312,346 5,237,614 Increases 54,908 256,581 311,489 Payments (85,259 ) (564,603 ) (649,862 ) Business combinations (Note 5) 288,352 38,781 327,133 Currency translation differences (140,502 ) (49,679 ) (190,181 ) Reclassifications (655,093 ) 655,093 - Balance as of December 31, 2021 4,387,674 648,519 5,036,193 The decrease in total project debt as of December 31, 2021 were primarily due to: - the repayment of project debt for the period in accordance with the financing arrangements; and - the lower value of debt denominated in Euros given the depreciation of the Euro against the U.S. dollar since December 31, 2020. The decrease of project debt during the year 2021 was partially offset by the business combinations, being the acquisitions of Rioglass, Coso, Chile PV 2, Italy PV 1 and Italy PV 3 for a total amount of $327 million (Note 5). Interest accrued, which are included in Increases, were offset by a similar amount of interest paid during the year, included in Payments in the table above. The Kaxu project financing arrangement contains cross-default provisions related to Abengoa such that debt defaults by Abengoa, subject to certain threshold amounts and/or a restructuring process, could trigger a default under the Kaxu project financing arrangement. The insolvency filing by the individual company Abengoa S.A. in February 2021 represented a theoretical event of default under the Kaxu project finance agreement. In September 2021, the Company obtained a waiver for such theoretical event of default and it was extended until April 30, 2022 and was subject to the lenders receiving certain documentation from the Company. Although the Company did not expect the acceleration of debt to be declared by the credit entities, as of December 31, 2021 Kaxu did not have what International Accounting Standards define as an unconditional right to defer the settlement of the debt for at least twelve months, as the cross-default provisions make that right conditional. Therefore, Kaxu total debt, previously presented as non-current as of December 31, 2020, was presented as current in the Consolidated Financial Statements of the Company as of December 31, 2021 for an amount of $314 million (Note 1). The repayment schedule for project debt in accordance with the financing arrangements as of December 31, 2022, is as follows and is consistent with the projected cash flows of the related projects: 2023 2024 2025 2026 2027 Subsequent years Total Interest payment Nominal repayment 15,053 311,481 323,731 442,920 358,444 504,954 2,596,469 4,553,052 The repayment schedule for project debt in accordance with the financing arrangements and assuming there would be no acceleration at the Kaxu debt as of December 31, 2021, was as follows and was consistent with the projected cash flows of the related projects: 2022 2023 2024 2025 2026 Subsequent years Total Interest payment Nominal repayment 18,017 317,388 355,956 369,528 498,712 411,514 3,065,078 5,036,193 The following table details the movement in project debt for the years 2022 and 2021, split between cash and non-cash items: Project Debt 2022 2021 Initial balance 5,036,193 5,237,614 Cash changes (636,343 ) (636,831 ) Non-cash changes 153,202 435,410 Final balance 4,553,052 5,036,193 The non-cash changes primarily relate to interest accrued, currency translation differences and the business combinations for the year. The equivalent in U.S. dollars of the foreign currency-denominated project debts held by the Company is as follows: Balance as of December 31, Currency 2022 2021 Euro 1,633,790 1,942,903 South African Rand 277,492 314,471 Algerian Dinar 86,739 97,877 Total 1,998,021 2,355,251 All of the Company’s financing agreements have a carrying amount close to its fair value.

Grants and other liabilities	Note 16.- Grants and other liabilities Grants and other liabilities as of December 31, 2022 and December 31, 2021 are as follows: Balance as of December 31, 2022 2021 Grants 911,593 970,557 Other liabilities and provisions 340,920 293,187 Dismantling provision 140,595 124,593 Lease liabilities 63,076 59,219 Accruals on Spanish market prices differences 91,884 74,795 Other 45,365 34,580 Grant and other non-current liabilities 1,252,513 1,263,744 As of December 31, 2022, the amount recorded in Grants corresponds primarily to the ITC Grant awarded by the U.S. Department of the Treasury to Solana and Mojave for a total amount of $610 million ($642 million as of December 31, 2021), which was primarily used to fully repay the Solana and Mojave short-term tranche of the loan with the Federal Financing Bank. 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 $299 million ($326 million as of December 31, 2021). 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 in “Other operating income” starting at the entry into operation of the plants. Total amount of income for these two types of grants for Solana and Mojave is $58.5 million and $58.7 million for the years ended December 31, 2022 and 2021, respectively (Note 20). The “Accruals on Spanish market prices differences” corresponds to the payables related to the current high market prices in Spain at which the solar assets in Spain inv oiced electricity up to December 31, 2022, The maturity of Other liabilities and provisions is as follows As of December 31, 2022 Total 2023 2024 and 2025 2026 and 2027 Subsequent years Other liabilities and provisions 340,920 - 46,489 41,428 253,003 Total 340,920 - 46,489 41,428 253,003 As of December 31, 2021 Total 2022 2023 and 2024 2025 and 2026 Subsequent years Other liabilities and provisions 293,187 - 51,490 33,656 208,041 Total 293,187 - 51,490 33,656 208,041

Down payments from clients in 2022 primarily include the collections from the CNMC (Spanish solar assets), which have been in line with the parameters corresponding to the regulation in place at the beginning of the year, as the new parameters became final on December 14, 2022, while revenue was recorded in accordance with the new parameters (Note 1). Nominal values of trade payables and other current liabilities are considered to approximately equal to fair values and the effect of discounting them is not significant.

Income Tax [Abstract]
Income Tax	Note 18.- Income Tax All the companies of Atlantica file income taxes according to the tax regulations in force in each country on an individual basis or under consolidation tax regulations. The consolidated income tax has been calculated as an aggregation of income tax expenses/income of each individual company. In order to calculate the taxable income of the consolidated entities individually, the accounting result is adjusted for temporary and permanent differences, recording the corresponding deferred tax assets and liabilities. At each consolidated income statement date, a current tax asset or liability is recorded, representing income taxes currently refundable or payable. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial statement and income tax purposes, as determined under enacted tax laws and rates. Income tax payable is the result of applying the applicable tax rate in force to each tax-paying entity, in accordance with the tax laws in force in the country in which the entity is registered. Additionally, tax deductions and credits are available to certain entities, primarily relating to inter-company trades and tax treaties between various countries to prevent double taxation. The Company offsets deferred tax assets and deferred tax liabilities in each entity where the latter has a legally enforceable right to set off current tax assets against current tax liabilities, and the deferred tax assets and liabilities relate to income taxes levied by the same taxation authority. As of December 31, 2022, and 2021, the analysis of deferred tax assets and deferred tax liabilities is as follows: Deferred tax assets Balance as of December 31, From 2022 2021 Net operating loss carryforwards (“NOL´s”) 442,415 323,115 Temporary tax non-deductible expenses 134,328 128,186 Derivatives financial instruments 3,461 55,217 Other 5,895 4,225 Total deferred tax assets 586,099 510,743 Deferred tax liabilities Balance as of December 31, From 2022 2021 Accelerated tax amortization 524,363 465,219 Other difference between tax and book value of assets 186,536 180,218 Derivatives financial instruments 19,034 - Other 2,991 1,897 Total deferred tax liabilities 732,924 647,334 After offsetting deferred tax assets and deferred tax liabilities, where applicable Consolidated balance sheets classifications Balance as of December 31, 2022 2021 Deferred tax assets 149,656 172,268 Deferred tax liabilities 296,481 308,859 Net deferred tax liabilities 146,825 136,591 Most of the NOL´s recognized as deferred tax assets corresponds to the entities in the U.S., South Africa, Peru, Chile and Spain as of December 31, 2022 and 2021. As of December 31, 2022, deferred tax assets for non-deductible expenses are primarily due to the temporary limitation of financial expenses deductibles for tax purposes in the solar plants in Spain for $94 million ($97 million as of December 31, 2021). As of December 31, 2022, deferred tax liabilities for accelerated tax amortization are primarily in the U.S. assets for $274 million, the solar plants in Spain for $173 million and Kaxu for $63 million ($184 million, $186 million and $76 million as of December 31, 2021, respectively). Deferred tax liabilities for other temporary differences between the tax and book value of contracted concessional assets relate primarily to ACT for $56 million, the U.S. entities for $51 million, the Peruvian entities for $37 million and the Chilean entities for $27 million as of December 31, 2022 ($72 million, $28 million, $34 million and $27 million as of December 31, 2021, respectively). In relation to tax losses carryforwards and deductions pending to be used recorded as deferred tax assets, the entities evaluate their recoverability projecting forecasted taxable result for the upcoming years and taking into account their tax planning strategy. Deferred tax liabilities reversals are also considered in these projections, as well as any limitation established by tax regulations in force in each tax jurisdiction. Therefore, the carrying amount of deferred tax assets is reviewed at each annual closing date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilised. Unrecognised deferred tax assets are re-assessed at each annual closing date and are recognised to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered. In assessing the recoverability of deferred tax assets, Atlantica relies on projections of results over the useful life of the contracted concessional assets. In addition, the Company has $361 million unrecognized net operating loss carryforwards as of December 31, 2022 ($346 million as of December 31, 2021), as it considers it is not probable that future taxable profits will be available against which these unused tax losses can be utilized. The movements in deferred tax assets and liabilities during the years ended December 31, 2022 and 2021 were as follows: Deferred tax assets Amount As of December 31, 2020 152,290 Increase/(decrease) through the consolidated income statement 46,855 Increase/(decrease) through other consolidated comprehensive income (equity) (23,712 ) Business combinations (Note 5) 4,410 Currency translation differences and other (7,575 ) As of December 31, 2021 172,268 Increase/(decrease) through the consolidated income statement 29,197 Increase/(decrease) through other consolidated comprehensive income (equity) (46,344 ) Currency translation differences and other (5,465 ) As of December 31, 2022 149,656 Deferred tax liabilities Amount As of December 31, 2020 260,923 Increase/(decrease) through the consolidated income statement 32,059 Business combinations (Note 5) 4,910 Currency translation differences and other 10,967 As of December 31, 2021 308,859 Increase/(decrease) through the consolidated income statement (19,864 ) Increase/(decrease) through other consolidated comprehensive income (equity) 17,608 Currency translation differences and other (10,122 ) As of December 31, 2022 296,481 Details of income tax for the years ended December 31, 2022, 2021 and 2020 are as follows: For the year ended December 31, 2022 2021 2020 Current tax (39,372 ) (51,016 ) (21,205 ) Deferred tax 49,061 14,796 (3,672 ) - relating to the origination and reversal of temporary differences 49,061 14,796 (3,672 ) Total income tax (expense)/income 9,689 (36,220 ) (24,877 ) The reconciliation between the theoretical income tax resulting from applying an average statutory tax rate to profit before income tax and the actual income tax expense recognized in the consolidated income statements for the years ended December 31, 2022, 2021, and 2020, is as follows: For the year ended December 31, 2022 2021 2020 Consolidated profit/(loss) before taxes (11,776 ) 25,302 41,751 Average statutory tax rate 25 % 25 % 25 % Corporate income tax at average statutory tax rate 2,944 (6,326 ) (10,438 ) Income tax of associates, net 5,366 3,076 128 Differences in statutory tax rates (4,296 ) (3,359 ) (94 ) Unrecognized NOLs and deferred tax assets (10,944 ) (11,232 ) (37,183 ) Purchase of Liberty Interactive’s equity interest in Solana - - 36,352 Other permanent differences 3,957 (4,052 ) (8,895 ) Other non-taxable income/(expense) 12,662 (14,327 ) (4,747 ) Corporate income tax 9,689 (36,220 ) (24,877 ) For the year ended December 31, 2021, the overall effective tax rate was different than the average statutory rate of 25% primarily due to unrecognized tax losses carryforwards, mainly in the UK entities and to provisions recorded for potential tax contingencies in some jurisdictions. For the year ended December 31, 2020, the overall effective tax rate was different than the average statutory rate of 25% primarily due to unrecognized tax losses carryforwards, mainly in the UK entities, partially offset by the non-taxable gain recorded in the Consolidated Financial Statements on the purchase of Liberty Interactive’s equity interest in Solana (Note 21). Uncertain tax positions as of December 31, 2022, 2021 and 2020 has been analysed by the Company in accordance with IFRIC 23 (uncertainty over income tax treatments). As a result of this analysis, the Company concluded that the risk of the uncertainties is remote and accordingly, the expectation is that these uncertainties would have an insignificant effect on the Consolidated Financial Statements.

Corporate debt guarantees The payment obligations under the Green Senior Notes, the Revolving Credit Facility, the Note Issuance Facility 2020 and the 2020 Green Private Placement are guaranteed on a senior unsecured basis by following subsidiaries of the Company: Atlantica Infraestructura Sostenible, S.L.U., Atlantica Peru, S.A., ACT Holding, S.A. de C.V., Atlantica Investments Limited, Atlantica Newco Limited and Atlantica North America LLC. The Revolving Credit Facility and the 2020 Green Private Placement are also secured with a pledge over the shares of the subsidiary guarantors. 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 S.A. 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 I, 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. Atlantica is not a party to any other significant legal proceedings other than legal 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.

Financial expense, net	Note 21.- Financial expense, net The following table sets forth financial income and expenses for the years ended December 31, 2022, 2021 and 2020: For the year ended December 31, Financial income 2022 2021 2020 Interest income from loans and credits 1,641 2,066 6,651 Interest rates benefits derivatives: cash flow hedges 3,928 689 401 Total 5,569 2,755 7,052 For the year ended December 31, Financial expenses 2022 2021 2020 Interest on loans and notes (292,043 ) (302,558 ) (316,237 ) Interest rates losses derivatives: cash flow hedges (41,220 ) (58,712 ) (62,149 ) Total (333,263 ) (361,270 ) (378,386 ) Financial interest income from loans and credits included in 2020 a non-monetary financial income of $3.8 million resulting from the refinancing of the debt of Cadonal. Interest on loans and notes primarily include interest on corporate and project debt, which decrease in 2022 and 2021 compared to the previous year, primarily due to the repayment of project and corporate debt in accordance with the financing arrangements. 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 in 2022 compared to 2021 is due to an increase in the spot interest rates in 2022 compared to 2021, 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 the business of the Company. The increase in profit in 2022 is mainly due to the impact of foreign exchange caps instruments hedging the net cash flows of the Company in Euros, resulting from the appreciation of the U.S. dollar against the Euro. Other financial income/(expense), net The following table sets out Other financial income/(expense), net for the years 2022, 2021 and 2020: For the year ended December 31, Other financial income/(expense), net 2022 2021 2020 Other financial income 27,938 32,321 162,290 Other financial losses (21,435 ) (16,571 ) (121,415 ) Total 6,503 15,750 40,875 Other financial income in 2022 include $6.2 million of income for non-monetary change to the fair value of derivatives of Kaxu for which hedge accounting is not applied, and $12.0 million income further to the change in the fair value of the conversion option of the Green Exchangeable Notes since December 2021 (Note 14). Residual items primarily relate to interest on deposits and loans, including non-monetary changes to the amortized cost of such loans. The decrease of other financial income in 2021 compared to the year 2020 is primarily due to the gain of $145 million further to the purchase of Liberty Interactive´s equity interest in Solana accounted for in 2020. Other financial losses primarily include guarantees and letters of credit, other bank fees, non-monetary changes to the fair value of derivatives which hedge accounting is not applied and of financial instruments recorded at fair value through profit and loss, and non-monetary changes to the present value of provision and other long-term liabilities. The decrease of other financial losses in 2021 compared to the year 2020 was primarily due to $73 million of financial expenses further to the refinancing of the Helios 1&2 debts accounted for in 2020 and a $16 million expense further to the change in the fair value of the conversion option of the Green Exchangeable Notes in 2020.

Earnings per share [Abstract]
Earnings per share	Note 22.- 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 year 2022 has been calculated considering the potential issuance of 3,347,305 shares (3,347,305 shares as of December 31, 2021 and December 31, 2020) on the settlement of the Green Exchangeable Notes (Note 14) and the potential issuance of 596,681 shares ( as of December 31, 2021) For the year ended December 31, Item 2022 2021 2020 Profit/(loss) attributable to Atlantica (5,443 ) (30,080 ) 11,968 Average number of ordinary shares outstanding (thousands) - basic 114,695 111,008 101,879 Average number of ordinary shares outstanding (thousands) - diluted 118,501 114,523 103,392 Earnings per share for the year (US dollar per share) - basic (0.05 ) (0.27 ) 0.12 Earnings per share for the year (US dollar per share) - diluted () (0.05 ) (0.27 ) 0.12 () The potential ordinary shares related to the Green Exchangeable Notes and the ATM program have not been considered in the calculation of diluted earnings per share for the years 2022 and 2021 as they have an antidilutive effect.

Other information [Abstract]
Other information	Note 23.- Other information 23.1 Restricted Net assets Certain of the consolidated entities are restricted from remitting certain funds to Atlantica Sustainable Infrastructure plc. as a result of a number of regulatory, contractual or statutory requirements. These restrictions are mainly related to standard requirements to maintain debt service coverage ratios and other requirements from the financing arrangements. At December 31, 2022, the accumulated amount of the temporary restrictions for the entire restricted term of these affiliates was $286 million. The Company performed a test on the restricted net assets of consolidated subsidiaries in accordance with Securities and Exchange Commission Regulation S-X Rule 12-04 and concluded the restricted net assets did not exceed 25% of the consolidated net assets of the Company as of December 31, 2022. Therefore, separate financial statements of Atlantica Sustainable Infrastructure, plc. do not have to be presented. 23.2 Subsequent events On February 22, 2023, the Company signed an agreement to terminate the operation and maintenance services performed by Abengoa to some of its solar assets in Spain. The transfer of employees from an Abengoa subsidiary to a Company’s subsidiary is expected to be effective on March 1, 2023. On February 28, 2023, the Board of Directors of the Company approved a dividend of $0.445 per share, which is expected to be paid on March 25, 2023.

Significant accounting policies [Abstract]
Basis of preparation	2.1 Basis of preparation These Consolidated Financial Statements are presented in accordance with the International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The Consolidated Financial Statements are presented in U.S. dollars, which is the Company’s functional and presentation currency. Amounts included in these Consolidated Financial Statements are all expressed in thousands of U.S. dollars, unless otherwise indicated. The Company presents assets and liabilities in the statement of financial position based on current/non-current classification. An asset or liability is current when it is expected or due to be realized within twelve months after the reporting period. The Company recognises that there may be potential financial implications in the future from changes in legislation and regulation implemented to address climate change risk. Over time these changes may have an impact across a number of areas of accounting. However, as at the reporting sheet date, the Company believes there is no material impact on the balance sheet carrying values of assets or liabilities. Application of new accounting standards a) Standards, interpretations and amendments effective from January 1, 2022 under IFRS-IASB, applied by the Company in the preparation of these Consolidated Financial Statements: The applications of these amendments have not had any impact on these financial statements. b) Standards, interpretations and amendments published by the IASB that will be effective for periods beginning on or after January 1, 2023: The Company does not anticipate any significant impact on the Consolidated 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, 2023, 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.
Principles to include and record companies in the consolidated financial statements	2.2. Principles to include and record companies in the consolidated financial statements Companies included in these Consolidated Financial Statements are accounted for as subsidiaries as long as Atlantica has control over them and are accounted for as investments under the equity method as long as Atlantica has significant influence over them, in the periods presented. a) Controlled entities Control is achieved when the Company: ● Has power over the investee; ● Is exposed, or has rights, to variable returns from its involvement with the investee; and ● Has the ability to use its power to affect its returns. The Company reassesses whether or not it controls an investee when facts and circumstances indicate that there are changes to one or more of the three elements of control listed above. The Company uses the acquisition method to account for business combinations of companies previously controlled by a third party. According to this method, identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. Any contingent consideration is recognized at fair value at the acquisition date and subsequent changes in its fair value are recognized in accordance with IFRS 9 in profit or loss. Acquisition related costs are expensed as incurred. The Company recognizes any non-controlling interest in the acquiree either at fair value or at the non-controlling interest’s proportionate share of the acquirer’s net assets on an acquisition by acquisition basis. All assets and liabilities between entities of the group, equity, income, expenses, and cash flows relating to transactions between entities of the group are eliminated in full. b) Investments accounted for under the equity method An associate is an entity over which the Company has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies. A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control. The results and assets and liabilities of associates and joint ventures are incorporated in these financial statements using the equity method of accounting. Under the equity method, an investment in an associate or joint venture is initially recognized in the statement of financial position at fair value and adjusted thereafter to recognize changes in Atlantica´s share of net assets of the associate or joint venture since the acquisition date. Any goodwill relating to the associate or joint venture is included in the carrying amount of the investment and is not tested for impairment separately. Controlled entities, associates and joint ventures included in these financial statements as of December 31, 2022 and 2021 are set out in appendices.
Contracted concessional, Property, Plant and Equipment (PP&E) and other intangible assets	2.3. Contracted concessional, Property, Plant and Equipment (PP&E) and other intangible The assets accounted for by the Company as contracted concessional assets under IFRIC 12 (either intangible model or financial model), as PP&E under IAS 16 or as other intangible assets under IAS 38 or under IFRS 16 (as “Lessee” or “Lessor”), include renewable energy assets, transmission lines, efficient natural gas assets and water plants. a) Contracted concessional assets under IFRIC 12 The infrastructure used in a concession accounted for under IFRIC 12 can be classified as an intangible asset or a financial asset, depending on the nature of the payment entitlements established in the agreement. The application of IFRIC 12 requires extensive judgement in relation to, among other factors, (i) the identification of certain infrastructures and contractual agreements in the scope of IFRIC 12, (ii) an understanding of the nature of the payments in order to determine the classification of the infrastructure as a financial asset or as an intangible asset and (iii) the timing and recognition of revenue from construction and concessionary activity. Under the terms of contractual arrangements within the scope of this interpretation, the operator shall recognize and measure revenue in accordance with IFRS 15 for the services it performs. The useful life of these assets is approximately the same as the length of the concession arrangement. Intangible assets The Company recognizes an intangible asset to the extent that it receives a right to charge final customers for the use of the infrastructure. This intangible asset is subject to the provisions of IAS 38 and is amortized linearly, taking into account the estimated period of commercial operation of the infrastructure which coincides with the concession period. Once the infrastructure is in operation, the treatment of income and expense is as follows: - Revenues from the updated annual revenue for the contracted concession, as well as revenues from operations and maintenance services are recognized in each period according to IFRS 15 “Revenue from contracts with Customers”. - Operating and maintenance costs and general overheads and administrative costs are recorded in accordance with the nature of the cost incurred (amount due) in each period. Financial asset The Company recognizes a financial asset when demand risk is assumed by the grantor, to the extent that the concession holder has an unconditional right to receive payments for the asset. This asset is recognized at the fair value of the construction services provided, considering upgrade services in accordance with IFRS 15, if any. The financial asset is subsequently recorded at amortized cost calculated according to the effective interest method, using a theoretical internal return rate specific to the asset. Revenue from operations and maintenance services is recognized in each period according to IFRS 15 “Revenue from contracts with Customers”. Allowance for expected credit losses (financial assets) According to IFRS 9, Atlantica recognizes an allowance for expected credit losses (ECLs) for all debt instruments not held at fair value through profit or loss. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Company expects to receive. There are two main approaches to applying the ECL model according to IFRS 9: the general approach which involves a three stage approach, and the simplified approach, which can be applied to trade receivables, contract assets and lease receivables. Atlantica applies the simplified approach. Under this approach, there is no need to monitor for significant increases in credit risk and entities will be required to measure lifetime expected credit losses at the end of each reporting period. The key elements of the ECL calculations, based on external sources of information, are the following: - the Probability of Default (“PD”) is an estimate of the likelihood of default over a given time horizon. Atlantica calculates PD based on Credit Default Swaps spreads (“CDS”); - the Exposure at Default (“EAD”) is an estimate of the exposure at a future default date; - the Loss Given Default (“LGD”) is an estimate of the loss arising in the case where a default occurs at a given time. It is based on the difference between the contractual cash flows due and those that the Company would expect to receive. It is expressed as a percentage of the EAD. b) Property, plant and equipment under IAS 16 Property, plant and equipment is measured at historical cost, including all expenses directly attributable to the acquisition, less depreciation and impairment losses, with the exception of land, which is presented net of any impairment losses. Such cost includes the cost of replacing part of the plant and equipment and borrowing costs for long-term installation projects if the recognition criteria are met. Repair and maintenance costs are recognized in profit or loss as incurred. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets. The Company reviews the estimated residual values and expected useful lives of assets at least annually. In particular, the Company considers the impact of health, safety and environmental legislation in its assessment of expected useful lives and estimated residual values. An item of property, plant and equipment and any significant part initially recognized is derecognized upon disposal (i.e., at the date the recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the statement of profit or loss when the asset is derecognized. c) Rights of use under IFRS 16 The Company assesses at contract inception whether a contract is, or contains, a lease. That is, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Company as a lessee: The Company applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value assets. The Company recognizes lease liabilities to make lease payments and right-of-use assets representing the right to use the underlying assets. Main right of use agreements correspond to land rights. The Company recognizes right-of-use assets at the commencement date of the lease (i.e. the date the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities (Note 2.11). The cost of right-of-use assets includes the amount of lease liabilities recognised, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received. Right-of-use assets are depreciated on a straight-line basis over the shorter of the lease term and the estimated useful lives of the assets. d) Other intangible assets Other intangible assets acquired separately are measured on initial recognition at cost. The cost of intangible assets acquired in a business combination is their fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. Intangible assets are amortized over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. An intangible asset is derecognised upon disposal (i.e., at the date the recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising upon derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the statement of profit or loss. Research and development costs: Research costs are expensed as incurred. Development expenditures on an individual project are recognised as an intangible asset when the Company can demonstrate: - the technical feasibility of completing the intangible asset so that the asset will be available for use or sale - its intention to complete and its ability and intention to use or sell the asset - how the asset will generate future economic benefits - the availability of resources to complete the asset - the ability to measure reliably the expenditure during development. Following initial recognition of the development expenditure as an asset, the asset is carried at cost less any accumulated amortization and accumulated impairment losses. Amortization of the asset begins when development is complete, and the asset is available for use. It is amortized over the period of expected future benefit. During the period of development, the asset is tested for impairment annually. e) Asset impairment Atlantica reviews its contracted concessional assets to identify any indicators of impairment at least annually, except for ECL assessment for financial assets which is discussed above. When impairment indicators exist, the Company calculates the recoverable amount of the asset. The recoverable amount of an asset is the higher of its fair value less costs to sell and its value in use, defined as the present value of the estimated future cash flows to be generated by the asset. In the event that the asset does not generate cash flows independently of other assets, the Company calculates the recoverable amount of the Cash Generating Unit (‘CGU’) to which the asset belongs. When the carrying amount of the CGU to which these assets belong is higher than its recoverable amount, the assets are impaired. Assumptions used to calculate value in use include a discount rate and projections considering real data based in the contracts terms and projected changes in both selling prices and costs. The discount rate is estimated by Management, to reflect both changes in the value of money over time and the risks associated with the specific CGU. For contracted concessional assets, with a defined useful life and with a specific financial structure, cash flow projections until the end of the project are considered and no relevant terminal value is assumed. Contracted concessional assets have a contractual structure that permits the Company to estimate quite accurately the costs of the project and revenue during the life of the project. Projections take into account real data based on the contract terms and fundamental assumptions based on specific reports prepared internally and third-party reports, assumptions on demand and assumptions on production. Additionally, assumptions on macro-economic conditions are taken into account, such as inflation rates, future interest rates, etc. and sensitivity analyses are performed over all major assumptions which can have a significant impact in the value of the asset. Cash flow projections of CGUs are calculated in the functional currency of those CGUs and are discounted using rates that take into consideration the risk corresponding to each specific country and currency. Taking into account that in most CGUs the specific financial structure is linked to the financial structure of the projects that are part of those CGUs, the discount rate used to calculate the present value of cash-flow projections is based on the weighted average cost of capital (WACC) for the type of asset, adjusted, if necessary, in accordance with the business of the specific activity and with the risk associated with the country where the project is performed. In any case, sensitivity analyses are performed, especially in relation to the discount rate used and fair value changes in the main business variables, in order to ensure that possible changes in the estimates of these items do not impact the recovery of recognized assets. In the event that the recoverable amount of an asset is lower than its carrying amount, an impairment charge for the difference would be recorded in the income statement under the item “Depreciation, amortization and impairment charges”. An assessment is made at each reporting date to determine whether there is an indication that previously recognized impairment losses no longer exist or have decreased. If such indication exists, the Company estimates the CGU’s recoverable amount. A previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the asset’s recoverable amount since the last impairment loss was recognized. The reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount, nor exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in the income statement.
Revenue Recognition	2.4. R evenue recognition According to IFRS 15, Revenue from Contracts with Customers, the Company assesses the goods and services promised in the contracts with the customers and identifies as a performance obligation each promise to transfer to the customer a good or service (or a bundle of goods or services). In the case of contracts related to intangible or financial assets under IFRIC 12, the performance obligation of the Company is the operation of the asset. The contracts between the parties set the price of the service in an orderly transaction and therefore corresponds to the fair value of the service provided. The service is satisfied over time. The same conclusion applies to concessional assets that are classified as tangible assets under IAS 16 or leases under IFRS 16. All of the transaction prices of assets under IFRIC 12 are fixed and included as part of the long-term PPAs of the Company as disclosed in Appendix III-2. In the case of financial asset under IFRIC 12, the financial asset accounts for the payments to be received from the client over the residual life of the contract, discounted at a theoretical internal rate of return for the project. In each period, the financial asset is reduced by the amounts received from the client and increased by any capital expenditure that the project may incur and by the effect of unwinding the discount of the financial asset at the theoretical internal rate of return. The increase of the financial asset deriving from the unwinding of the discount of the financial asset is recorded as revenue in each period. Revenue will therefore differ from the actual billings made to the client in each period. In the case of Spain, according to Royal Decree 413/2014, solar electricity producers receive: (i) the market price for the power they produce, (ii) a payment based on the standard investment cost for each type of plant (without any relation whatsoever to the amount of power they generate) and (iii) an “operating payment” (in €/MWh produced). The principle driving this economic regime is that the payments received by a renewable energy producer should be equivalent to the costs that they are unable to recover on the electricity pool market where they compete with non-renewable technologies. This economic regime seeks to allow a “well-run and efficient enterprise” to recover the costs of building and running a plant, plus a reasonable return on investment (project investment rate of return). Some of the Company´s assets in Spain are receiving a remuneration based on a 7.09% reasonable rate of return until December 31, 2025 while others are receiving a remuneration based on a 7.398% reasonable rate of return until December 31, 2031.
Loans and accounts receivable	2.5. Loans and accounts receivable Loans and accounts receivable are non-derivative financial assets with fixed or determinable payments, not listed on an active market. In accordance with IFRIC 12, certain assets under concessions qualify as financial assets and are recorded as is described in Note 2.3. Pursuant to IFRS 9, an impairment loss is recognized if the carrying amount of these assets exceeds the present value of future cash flows discounted at the initial effective interest rate. Loans and accounts receivable are initially recognized at fair value plus transaction costs and are subsequently measured at amortized cost in accordance with the effective interest rate method. Interest calculated using the effective interest rate method is recognized under other financial income within financial income.
Derivative financial instruments and hedging activities	2.6. Derivative financial instruments and hedging activities Derivatives are recognized at fair value in the statement of financial position. The Company maintains both derivatives designated as hedging instruments in hedging relationships, and derivatives to which hedge accounting is not applied. When hedge accounting is applied, hedging strategy and risk management objectives are documented at inception, as well as the relationship between hedging instruments and hedged items. Effectiveness of the hedging relationship needs to be assessed on an ongoing basis. Effectiveness tests are performed prospectively at inception and at each reporting date. The Company analyses on each date if all these requirements are met: - there is an economic relationship between the hedged item and the hedging instrument; - the effect of credit risk does not dominate the value changes that result from that economic relationship; and - the hedge ratio of the hedging relationship is the same as that resulting from the quantity of the hedged item that the Company actually hedges and the quantity of the hedging instrument that the Company uses to hedge that quantity of hedged item. Ineffectiveness is measured following the accumulated dollar offset method. In all cases, current Company´s hedging relationships are considered cash flow hedges. Under this model, the effective portion of changes in fair value of derivatives designated as cash flow hedges are recorded temporarily in equity and are subsequently reclassified from equity to profit or loss in the same period or periods during which the hedged item affects profit or loss. Any ineffective portion of the hedged transaction is recorded in the consolidated income statement as it occurs. When interest rate options are designated as hedging instruments, the time value is excluded from the hedging instrument as permitted by IFRS 9. Changes in the effective portion of the intrinsic are recorded in equity and subsequently reclassified from equity to profit or loss in the same period or periods during which the hedged item affects profit or loss. Any ineffectiveness is recorded as financial income or expense as it occurs. Changes in options time value is recorded as cost of hedging. More precisely, considering that the hedged items are, in all cases, time period hedged item, changes in time value is recognized in other comprehensive income to the extent that it relates to the hedged item. The time value at the date of designation of the option as a hedging instrument, to the extent that it relates to the hedged item, is amortized on a systematic and rational basis over the period during which the hedge adjustment for the option’s intrinsic value could affect profit or loss. When the hedging instrument matures or is sold, or when it no longer meets the requirements to apply hedge accounting, accumulated gains and losses recorded in equity remain as such until the forecast transaction is ultimately recognized in the income statement. However, if it becomes unlikely that the forecast transaction will actually take place, the accumulated gains and losses in equity are recognized immediately in the income statement. Any change in fair value of derivatives instruments to which hedge accounting is not applied is directly recorded in the income statement.
Fair value estimates	2.7. Fair value estimates Financial instruments measured at fair value are presented in accordance with the following level classification 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. In the event that prices cannot be observed, management shall make its best estimate of the price that the market would otherwise establish based on proprietary internal models which, in the majority of cases, use data based on observable market parameters as significant inputs (Level 2) but occasionally use market data that is not observed as significant inputs (Level 3). Different techniques can be used to make this estimate, including extrapolation of observable market data. The best indication of the initial fair value of a financial instrument is the price of the transaction, except when the value of the instrument can be obtained from other transactions carried out in the market with the same or similar instruments, or valued using a valuation technique in which the variables used only include observable market data, mainly interest rates. Differences between the transaction price and the fair value based on valuation techniques that use data that is not observed in the market, are not initially recognized in the income statement. Atlantica derivatives correspond primarily to the interest rate swaps designated as cash flow hedges, which are classified as Level 2. Description of the valuation method Interest rate swap valuations consist in valuing separately the swap part of the contract and the credit risk. The methodology used by the market and applied by Atlantica to value interest rate swaps is to discount the expected future cash flows according to the parameters of the contract. Variable interest rates, which are needed to estimate future cash flows, are calculated using the curve for the corresponding currency and extracting the implicit rates for each of the reference dates in the contract. These estimated flows are discounted with the swap zero curve for the reference period of the contract. The effect of the credit risk on the valuation of the interest rate swaps depends on the future settlement. If the settlement is favorable for the Company, the counterparty credit spread will be incorporated to quantify the probability of default at maturity. If the expected settlement is negative for the Company, its own credit risk will be applied to the final settlement. Classic models for valuing interest rate swaps use deterministic valuation of the future of variable rates, based on future outlooks. When quantifying credit risk, this model is limited by considering only the risk for the current paying party, ignoring the fact that the derivative could change sign at maturity. A payer and receiver swaption model is proposed for these cases. This enables the associated risk in each swap position to be reflected. Thus, the model shows each agent’s exposure, on each payment date, as the value of entering into the ‘tail’ of the swap, i.e. the live part of the swap. Variables (Inputs) Interest rate derivative valuation models use the corresponding interest rate curves for the relevant currency and underlying reference in order to estimate the future cash flows and to discount them. Market prices for deposits, futures contracts and interest rate swaps are used to construct these curves. Interest rate options (caps and floors) also use the volatility of the reference interest rate curve. To estimate the credit risk of the counterparty, the credit default swap (CDS) spreads curve is obtained in the market for important individual issuers. For less liquid issuers, the spreads curve is estimated using comparable CDSs or based on the country curve. To estimate proprietary credit risk, prices of debt issues in the market and CDSs for the sector and geographic location are used. The fair value of the financial instruments that results from the aforementioned internal models takes into account, among other factors, the terms and conditions of the contracts and observable market data, such as interest rates, credit risk and volatility. The valuation models do not include significant levels of subjectivity, since these methodologies can be adjusted and calibrated, as appropriate, using the internal calculation of fair value and subsequently compared to the corresponding actively traded price. However, valuation adjustments may be necessary when the listed market prices are not available for comparison purposes.
Trade and other receivables	2.8. Trade and other receivables Trade and other receivables are amounts due from customers for sales in the normal course of business. They are recognized initially at fair value and subsequently measured at amortized cost using the effective interest rate method, less allowance for doubtful accounts. Trade receivables due in less than one year are carried at their face value at both initial recognition and subsequent measurement, provided that the effect of not discounting flows is not significant. An allowance for doubtful accounts is recorded when there is objective evidence that the Company will not be able to recover all amounts due as per the original terms of the receivables. The Company has established a provision matrix that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment.
Cash and cash equivalents	2.9. Cash and cash equivalents Cash and cash equivalents include cash in hand, cash in bank and other highly-liquid current investments with an original maturity of three months or less which are held for the purpose of meeting short-term cash commitments.
Grants	2.10. Grants Grants are recognized at fair value when it is considered that there is a reasonable assurance that the grant will be received and that the necessary qualifying conditions, as agreed with the entity assigning the grant, will be adequately complied with. Grants are recorded as liabilities in the consolidated statement of financial position and are recognized in “Other operating income” in the consolidated income statement based on the period necessary to match them with the costs they intend to compensate. In addition, as described in Note 2.11 below, grants correspond also to loans with interest rates below market rates, for the initial difference between the fair value of the loan and the proceeds received.
Loans and borrowings	2.11. Loans and borrowings Loans and borrowings are initially recognized at fair value, net of transaction costs incurred. Borrowings are subsequently measured at amortized cost and any difference between the proceeds initially received (net of transaction costs incurred in obtaining such proceeds) and the repayment value is recognized in the consolidated income statement over the duration of the borrowing using the effective interest rate method. In the case of modification of terms of loans and borrowings, the Company determines whether the modification constitutes an exchange or an extinguishment of the debt instrument. In determining whether there is an exchange, the Company evaluates whether the redemption of the old debt and the issuance of new debt were negotiated in contemplation of one another (qualitative assessment) and performs the 10 per cent test to determine if the terms of the modified debt are substantially different (the net present value of the modified cash flows, including any fees paid net of any fees received, is higher than 10% different from the net present value of the remaining cash flows of the liability prior to the modification, both discounted at the original effective interest rate). When the terms of the modified liability are substantially different, the modification is accounted for as an extinguishment of the original liability and recognition of a new liability. Loans with interest rates below market rates are initially recognized at fair value in liabilities and the difference between proceeds received from the loan and its fair value is initially recorded within “Grants and Other liabilities” in the consolidated statement of financial position, and subsequently recorded in “Other operating income” in the consolidated income statement when the costs financed with the loan are expensed. Lease liabilities are recognized by the Company at the commencement date of the lease at the present value of lease payments to be made over the lease term. The lease payments include the exercise price of a purchase option reasonably certain to be exercised by the Company and payments of penalties for terminating the lease, if the lease term reflects the Company exercising the option to terminate. In calculating the present value of lease payments, the Company uses its incremental borrowing rate at the lease commencement date considering that the interest rate implicit in the lease is not readily determinable.
Bonds and notes	2.12. Bonds and notes The Company initially recognizes ordinary notes at fair value, net of issuance costs incurred. Subsequently, notes are measured at amortized cost until settlement upon maturity. Any other difference between the proceeds obtained (net of transaction costs) and the redemption value is recognized in the consolidated income statement over the term of the debt using the effective interest rate method. Convertible bonds or notes or debt issued with conversion features must be separated into liability and equity components if the feature meets the equity classification conditions in IAS 32. The issuer separates the instrument into its components by determining the fair value of the liability component and then deducting that amount from the fair value of the instrument as a whole; the residual amount is allocated to the equity component. If the equity conversion feature does not satisfy the equity classification conditions in IAS 32, it is bifurcated as an embedded derivative unless the issuer elects to apply the fair value option to the convertible debt. The embedded derivative is initially recognized at fair value and classified as derivatives in the statement of financial position. Changes in the fair value of the embedded derivatives are subsequently accounted for directly through the income statement. The debt element of the bond or note (the host contract), will be initially valued as the difference between the consideration received from the holders for the instrument and the value of the embedded derivative, and thereafter at amortized cost using the effective interest method.
Income taxes	2.13. Income taxes Current income tax expense is calculated on the basis of the tax laws in force as of the date of the consolidated statement of financial position in the countries in which the subsidiaries and associates operate and generate taxable income. Deferred income tax is calculated in accordance with the liability method, based upon the temporary differences arising between the carrying amount of assets and liabilities and their tax base. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date. Deferred tax assets are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized.
Trade payables and other liabilities	2.14. Trade payables and other liabilities Trade payables are obligations arising from purchases of goods and services in the ordinary course of business and are recognized initially at fair value and are subsequently measured at their amortized cost using the effective interest method. Other liabilities are obligations not arising in the normal course of business and which are not treated as financing transactions. Advances received from customers are recognized as “Trade payables and other current liabilities”.
Foreign currency transactions	2.15. Foreign currency transactions The Consolidated Financial Statements are presented in U.S. dollars, which is Atlantica’s functional and presentation currency. Financial statements of each subsidiary within the Company are measured in the currency of the principal economic environment in which the subsidiary operates, which is the subsidiary’s functional currency. Transactions denominated in a currency different from the entity’s functional currency are translated into the entity’s functional currency applying the exchange rates in force at the time of the transactions. Foreign currency gains and losses that result from the settlement of these transactions and the translation of monetary assets and liabilities denominated in foreign currency at the year-end rates are recognized in the consolidated income statement, unless they are deferred in equity, as occurs with cash flow hedges and net investment in foreign operations hedges. Assets and liabilities of subsidiaries with a functional currency different from the Company’s reporting currency are translated to U.S. dollars at the exchange rate in force at the closing date of the financial statements. Income and expenses are translated into U.S. dollars using the average annual exchange rate, which does not differ significantly from using the exchange rates of the dates of each transaction. The difference between equity translated at the historical exchange rate and the net financial position that results from translating the assets and liabilities at the closing rate is recorded in equity under the heading “Accumulated currency translation differences”. Results of companies carried under the equity method are translated at the average annual exchange rate.
Equity	2.16. Equity The Company has recyclable balances in its equity, corresponding mainly to hedge reserves and translation differences arising from currency conversion in the preparation of these Consolidated Financial Statements. These balances have been presented separately in equity. Ordinary shares are classified as equity. Any excess above the par value of shares received upon issuance of those shares is classified as share premium. Capital reserves is mainly the result of reductions of the share premium account which have increased distributable reserves. Non-controlling interest represents interest of other partners in subsidiaries included in these Consolidated Financial Statements which are not fully owned by Atlantica as of the dates presented. The costs of issuing equity instruments are accounted for as a deduction from equity.
Provisions and contingencies	2.17. Provisions and contingencies Provisions are recognized when: - there is a present obligation, either legal or constructive, as a result of past events; - it is more likely than not that there will be a future outflow of resources to settle the obligation; and the amount has been reliably estimated. Provisions are measured at the present value of the expected outflows required to settle the obligation. The discount rate used is a current pre-tax rate that reflects, when appropriate, the risks specific to the liability. The increase in the provision due to the passage of time is then recognized as a financial expense. The balance of provisions disclosed in the Notes reflects management’s best estimate of the potential exposure as of the date of preparation of the Consolidated Financial Statements. Contingent liabilities are possible obligations, existing obligations with low probability of a future outflow of economic resources and existing obligations where the future outflow cannot be reliably estimated. Contingences are not recognized in the consolidated statements of financial position unless they have been acquired in a business combination. Some companies of Atlantica have dismantling provisions, which are intended to cover future expenditure related to the dismantlement of the plants in situations where it is likely to be settled with an outflow of resources in the long term (over 5 years). Such provisions are recognised when the obligation for dismantling, removing and restoring the site on which the plant is located, is incurred, which is usually during the construction period. The provision is measured in accordance with IAS 37, “Provisions, Contingent Liabilities and Contingent Assets” and is recorded as a liability under the heading “Grants and other liabilities” of the Financial Statements, and the corresponding entry as part of the cost of the plant under the heading “Contracted concessional assets.” The estimated future costs of dismantling are reviewed annually if conditions have changed and adjusted appropriately. The impact of changes in the estimate of future costs or in the timing of when such costs will be incurred, on the dismantling provision, is recorded against an increase or decrease of the cost of the plant.
Earnings per share	2.18. Earnings per share Basic earnings per share is calculated by dividing the profit for the period attributable to ordinary equity holders of the parent by the weighted average number of ordinary shares outstanding during the period. Diluted earnings per share is calculated by dividing the profit for the period attributable to ordinary equity holders of the parent by the weighted average number of ordinary shares outstanding during the period plus the weighted average number of ordinary shares that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares.
Significant judgements and estimates	2.19. Significant judgements and estimates Some of the accounting policies applied require the application of significant judgement by management to select the appropriate assumptions to determine these estimates. These assumptions and estimates are based on the 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 the businesses of the Company. By their nature, these judgements 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 reflect significant management estimates and judgement to determine amounts in these Consolidated Financial Statements, are as follows: Estimates: - Impairment of contracted concessional, PP&E and other intangible assets. Impairment exists when the carrying value of an asset or cash generating unit exceeds its recoverable amount, which is the higher of its fair value less costs of disposal and its value in use. The value in use calculation is based on a discounted cash flow model, which is sensitive to the discount rate used as well as projected cash-flows (Note 6). The significant assumptions which required substantial estimates used in management’s impairment calculation are discount rates and projections considering real data based on contract terms and projected changes in selling prices, energy generation and costs. - Recoverability of deferred tax assets. Deferred tax assets are recognised for unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be utilised. Significant management estimates are required to determine the amount of deferred tax assets that can be recognised, based upon the likely timing and the level of future taxable profits together with future tax planning strategies (Note 18). - Fair value of derivative financial instruments When the fair values of financial assets and financial liabilities recorded in the statement of financial position cannot be measured based on quoted prices in active markets, their fair value is measured using valuation techniques including the discounted cash flow model. The inputs to these models are taken from observable markets where possible, but where this is not feasible, a degree of estimate is required in establishing fair values. Estimates include considerations of inputs such as liquidity risk, credit risk and volatility. Changes in assumptions relating to these factors could affect the reported fair value of financial instruments. - Fair value of identifiable assets and liabilities arising from a business combination The assets acquired and liabilities assumed on a business combination are recognised at the fair values of the underlying items. The estimates that have a significant risk of causing a material adjustment to the carrying amounts of the assets and liabilities are the ones considered when performing impairment review of operating assets (see above). Judgements: - Assessment of assets agreements. By evaluating the terms and conditions of each assets agreement, the Company determines the accounting category to which the asset belongs, e.g. IAS 16, IFRIC 12 or IFRS 16 (Note 2.3.). - Assessment of control. Judgement is required in determining the nature of Atlantica´s interest in another entity and in determining if it has control, joint control or significant influence over it (Note 2.2.). As of the date of preparation of these Consolidated Financial Statements, no relevant changes in the estimates made are anticipated and, therefore, no significant changes in the value of the assets and liabilities recognized at December 31, 2022, 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 year in which the change occurs.
