During 2022, production in the renewable energy portfolio increased by 14.3%, a considerable increase compared with 2021 mainly thanks to the contribution from recent investments. In our solar assets in the US, production in 2022 increased due to higher solar radiation compared with 2021. Production also increased at Kaxu. On the other hand, production decreased in the year 2022 in our solar assets in Spain and in our wind assets in Uruguay, due to lower solar radiation and lower wind resource, respectively, compared to 2021.

In our efficient natural gas and heat, transmission lines and water segments, where revenue is based on availability, we maintained very high availability levels in 2022.

#### Liquidity and Debt

<br> • In November 2022, Atlantica was ranked 1st globally on GRESB's Infrastructure Public Disclosure rating.

<br> • In December 2022, Atlantica was included for the second consecutive year in the CDP "A List", achieving the highest score on environmental transparency and action in relation to climate change.

<br> • In January 2023, Atlantica was ranked for the third consecutive year by Global 100 amongst the World's 100 Most Sustainable Corporations.

• The construction of Coso Batteries 1, a battery storage system developed in-house located inside our Coso geothermal plant in California, recently announced. The battery system will have a capacity of 100 MWh (4 hours) and is expected to start operation in 2024. The project, which will benefit from the U.S. Inflation Reduction Act and from synergies with existing assets in the region, will represent an expected investment in a range between $40 and $50 million.

• Several solar PV assets in North America, Europe and South America, in which we expect to invest between $80 and $85 million.

• The expansion of two of our transmission lines in Peru, ATN and ATS, which are expected to represent an investment in a range between $18 and $20 million.

<sup>12</sup> Estimation of equity already invested, committed or earmarked for investment in 2023 in projects currently under construction or expected to start construction in 2023, including expansions and repowerings.

------

![](image00002.jpg)<br>

• Other investments, including storage in different geographies, for an amount in the range of $25 to $30 million.

#### Development Pipeline
As a result of the Company's increasing focus on growth through development and construction, we currently have a pipeline of projects under development, including both repowering and expansion opportunities of existing assets and greenfield development, of approximately 2.0 GW<sup>13</sup> of renewable energy and 5.6 GWh<sup>13</sup> of storage. Our pipeline consists mostly of PV, storage and wind and is mainly focused on North America. Approximately 18% of the projects are estimated to reach ready to build ("Rtb") in 2023 or 2024 and 17% are in an advanced development stage. Our pipeline also includes our first hydrogen project, that comprises a 10 MW PV facility and has recently won a $6.5 million grant.

With this, we are confident that we can continue delivering accretive growth to our shareholders.

#### 2023 Guidance
Atlantica is initiating guidance for 2023:

2023 expected Adjusted EBITDA in the range of $790 million to $850<sup>14</sup> million.<br>

2023 expected CAFD in the range of $235 million to $260 million.<br>

#### Strategic Review

The decision has the support of the Company's largest shareholder, Algonquin. Atlantica expects to continue executing on its existing plans while the review of strategic alternatives is ongoing, including its current growth plan. There is no assurance that any specific transaction will be consummated, or other strategic change will be implemented as a result of this strategic review.

This communication discusses a process to explore and evaluate potential strategic alternatives. There can be no assurance that the strategic review process will lead to the approval or completion of any transaction or other strategic change.

The 2023 CAFD and 2023 Adjusted EBITDA referred to in section "2023 Guidance" are estimates as of March 1, 2023. These estimates are based on assumptions believed to be reasonable as of the date Atlantica published its Full Year 2022 Financial Results. Atlantica disclaims any current intention to update such guidance, except as required by law.

### Non-GAAP Financial Measures
This press release also includes certain non-GAAP financial measures, including Adjusted EBITDA, CAFD and CAFD per share. Non-GAAP financial measures are not measurements of our performance or liquidity under IFRS as issued by IASB and should not be considered alternatives to operating profit or profit for the period or net cash provided by operating activities or any other performance measures derived in accordance with IFRS as issued by the IASB or any other generally accepted accounting principles or as alternatives to cash flow from operating, investing or financing activities. Please refer to the appendix of this press release for a reconciliation of the non-GAAP financial measures included in this press release to the most directly comparable financial measures prepared in accordance with IFRS. Also, please refer to the following paragraphs in this section for an explanation of the reasons why management believes the use of non-GAAP financial measures (including CAFD, CAFD per share and Adjusted EBITDA) in this press release provides useful information to investors.

We present non-GAAP financial measures because we believe that they and other similar measures are widely used by certain investors, securities analysts and other interested parties as supplemental measures of performance and liquidity. The non-GAAP financial measures may not be comparable to other similarly titled measures employed by other companies and may have limitations as analytical tools. These measures may not be fit for isolated consideration or as a substitute for analysis of our operating results as reported under IFRS as issued by the IASB. Non-GAAP financial measures and ratios are not measurements of our performance or liquidity under IFRS as issued by the IASB. Thus, they should not be considered as alternatives to operating profit, profit for the period, any other performance measures derived in accordance with IFRS as issued by the IASB, any other generally accepted accounting principles or as alternatives to cash flow from operating, investing or financing activities. Some of the limitations of these non-GAAP measures are:

------

![](image00002.jpg)<br>

&nbsp;&nbsp;&nbsp;&nbsp;• they do not reflect our cash expenditures, future requirements for capital expenditures or contractual commitments;

&nbsp;&nbsp;&nbsp;&nbsp;• they do not reflect changes in, or cash requirements for, our working capital needs;

&nbsp;&nbsp;&nbsp;&nbsp;• they may not reflect the significant interest expense, or the cash requirements necessary, to service interest or principal payments, on our debts;

&nbsp;&nbsp;&nbsp;&nbsp;• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often need to be replaced in the future and Adjusted EBITDA, CAFD and CAFD per share do not reflect any cash requirements
 that would be required for such replacements;

&nbsp;&nbsp;&nbsp;&nbsp;• some of the exceptional items that we eliminate in calculating Adjusted EBITDA reflect cash payments that were made, or will be made in the future; and

&nbsp;&nbsp;&nbsp;&nbsp;• the fact that other companies in our industry may calculate Adjusted EBITDA, CAFD and CAFD per share differently than we do, which limits their usefulness as comparative measures.

We define Adjusted EBITDA as profit/(loss) for the period attributable to the Company, after previously adding back loss/(profit) attributable to non-controlling interest, income tax, expense, financial expense (net), depreciation, amortization and impairment charges of entities included in the consolidated financial statements and depreciation and amortization, financial expense and income tax expense of unconsolidated affiliates (pro rata of our equity ownership).

CAFD is calculated as cash distributions received by the Company from its subsidiaries minus cash expenses of the Company, including debt service and general and administrative expenses. CAFD per share is calculated by dividing CAFD for the year by the weighted average number of shares for the year (114,694,880 for the year ended on December 31, 2022, and 111,008,350 for December 31, 2021).

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

------

![](image00002.jpg)<br>

Our management believes CAFD and CAFD per share are relevant supplemental measures of the Company's ability to earn and distribute cash returns to investors and are useful to investors in evaluating our operating performance because securities analysts and other interested parties use such calculations as a measure of our ability to make quarterly distributions. In addition, CAFD and CAFD per share are used by our management team for determining future acquisitions and managing our growth. Adjusted EBITDA, CAFD and CAFD per share are widely used by other companies in the same industry.

Our management uses Adjusted EBITDA, CAFD and CAFD per share as measures of operating performance to assist in comparing performance from period to period and aims to use them on a consistent basis moving forward. They also readily view operating trends as a measure for planning and forecasting overall expectations, for evaluating actual results against such expectations, and for communicating with our board of directors, shareholders, creditors, analysts and investors concerning our financial performance.

In our discussion of operating results, we have included foreign exchange impacts in our revenue and Adjusted EBITDA by providing constant currency growth. The constant currency presentation is not a measure recognized under IFRS and excludes the impact of fluctuations in foreign currency exchange rates. We believe providing constant currency information provides valuable supplemental information regarding our results of operations. We calculate constant currency amounts by converting our current period local currency revenue and Adjusted EBITDA using the prior period foreign currency average exchange rates and comparing these adjusted amounts to our prior period reported results. This calculation may differ from similarly titled measures used by others and, accordingly, the constant currency presentation is not meant to be a substitute for recorded amounts presented in conformity with IFRS as issued by the IASB nor should such amounts be considered in isolation.

Information presented as the pro-rata share of our unconsolidated affiliates reflects our proportionate ownership of each asset in our property portfolio that we do not consolidate and has been calculated by multiplying our unconsolidated affiliates' financial statement line items by our percentage ownership thereto. Note 7 to our consolidated financial statements as of and for the year ended December 31, 2022 includes a description of our unconsolidated affiliates and our pro rata share thereof. We do not control the unconsolidated affiliates. Multiplying our unconsolidated affiliates' financial statement line items by our percentage ownership may not accurately represent the legal and economic implications of holding a non-controlling interest in an unconsolidated affiliate. We include pro-rata share of depreciation and amortization, financial expense and income tax expense of unconsolidated affiliates because we believe it assists investors in estimating the effect of such items in the profit/(loss) of entities carried under the equity method (which is included in the calculation of our Adjusted EBITDA) based on our economic interest in such unconsolidated affiliates. Each unconsolidated affiliate may report a specific line item in its financial statements in a different manner. In addition, other companies in our industry may calculate their proportionate interest in unconsolidated affiliates differently than we do, limiting the usefulness of such information as a comparative measure. Because of these limitations, the information presented as the pro-rata share of our unconsolidated affiliates should not be considered in isolation or as a substitute for our or such unconsolidated affiliates' financial statements as reported under applicable accounting principles.

 <sup>15</sup> "Deposits into/ withdrawals from restricted accounts" and "Change in non-restricted cash at project level" are calculated on a constant currency basis to reflect actual cash movements isolated from the impact of variations generated by foreign exchange changes during the period.

 <sup>16</sup> The forward-looking measures of 2023 Adjusted EBITDA and CAFD are non-GAAP measures that cannot be reconciled to the most directly comparable GAAP financial measure without unreasonable effort primarily because of the uncertainties involved in estimating forward looking income tax expense, mark-to-market changes in derivatives, profit attributable to non-controlling interest and Share of loss/(profit) of entities carried under the equity method to arrive at net income and which are subtracted therefrom to arrive to CAFD.

 <sup>17</sup> Non-monetary items include (1) a positive non-cash adjustment for approximately $60.2 million corresponding to the difference between billings and revenue in assets accounted for as concessional financial assets, primarily related to ACT, (2) a positive non-cash adjustment of up to $65.5 million related to electricity market prices in Spain and (3) a negative non-cash adjustment of approximately $58.4 million related to income from cash grants in the U.S.
