REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
To the Shareholders and the Board of Directors of Atlantica Sustainable Infrastructure plc
 
Opinion on the Financial Statements
 
We have audited the accompanying consolidated statements of financial position of Atlantica Sustainable Infrastructure plc (the “Company”) as of December 31, 2021 and 2020, the related consolidated statements of income, comprehensive income, changes in equity and cash flows, for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with International Financial Reporting Standards as issued by International Accounting Standards Board.
 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 27, 2022 expressed an unqualified opinion thereon.
 
Basis for Opinion
 
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
 
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
 
Critical Audit Matter
 
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

                                Recoverability assessment of contracted concessional assets

Description of the Matter
 
As described in Note 6 to the consolidated financial statements, the Company has recorded “contracted concessional” assets of $8,021 million at December 31, 2021, which are primarily classified as intangible assets or financial assets depending on the nature of the payment entitlements established in the respective agreements. Revenue derived from the Company’s contracted concessional assets are governed by power purchase agreements (“PPAs”) with the Company’s customers or by regulation.

As described in Note 2 to the consolidated financial statements, the Company reviews its contracted concessional assets for impairment indicators whenever events or changes in circumstances indicate that the carrying amounts of the assets or group of assets may not be recoverable, or previous impairment losses are no longer adequate. As discussed in Note 6, management identified triggering events at the Solana asset located in the United States (the “Solana US Asset”) and recorded a $43 million impairment charge in 2021.

Auditing the Company’s recoverability assessment related to the contracted concessional assets involves significant judgment in determining whether impairment indicator existed and, if an indicator exists, in the assumptions used by management in the determination if an impairment should be recorded or reversed. The main inputs considered when evaluating for impairment indicators include the performance of the plants versus budget and changes in applicable regulations. The significant assumptions which required substantial judgement or estimation used in management’s impairment calculation of the Solana US Asset are discount rates and projections considering real data based on contract terms and projected changes in both selling prices and costs.

8

How We Addressed the Matter in Our Audit
 
We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s contracted concessional assets recoverability assessment process. For example, we tested controls over management’s identification of potential impairment indicators, as well as controls over the determination of significant assumptions used in the Solana US Asset impairment calculation, including, among others, the discount rates and underlying projections used in the Company’s impairment assessment.

To test the Company’s impairment indicators assessment for contracted concessional assets, our audit procedures included, among others, comparing actual energy production versus budget and assessing the effects of any identified changes to regulation impacting significant locations.

For the Solana US Asset, we evaluated the design and tested the operating effectiveness of controls over the current year impairment calculation, including management’s review of the significant assumptions used.

As part of our audit procedures on the Solana US Asset, we assessed the appropriateness of the main inputs used in the cash flow projections, by comparing the future estimated performance of the asset to its historical energy production and evaluating the consistency of the actual energy production versus budget for 2021. For the discount rate, we involved our valuation specialists to assist us in calculating and developing a range of discount rates, which we compared to those used by the Company.

We assessed the adequacy of the related disclosures in the Company’s financial statements, including the sensitivity analyses on the energy production and discount rate assumptions.
