Operational KPIs

Production in the renewable business portfolio decreased by 4.6% for the first half of 2024 compared with the first half of 2023.

Production increased in our U.S. solar assets mainly due to higher availability of the Solana storage system. Production also increased in our wind assets in the U.S. due to higher wind resource in the first half of 2024 compared to the same period of 2023. In South America, production increased due to higher production in our wind assets and to the contribution of solar assets that have recently entered into operation. In Spain, production at our solar assets decreased mainly as a result of significantly lower solar radiation. At Kaxu, production decreased due to the unscheduled outage that started at the end of September 2023. The plant, where we have 51% equity interest, restarted operations in mid-February 2024. Part of the damage and business interruption has been covered by our insurance policy, after a 60-day deductible.

Our efficient natural gas and heat assets, our water assets, and our transmission lines, for which revenue is based on availability, continued at very high levels during the first six months of 2024.

Liquidity and Debt

As of June 30, 2024, cash at Atlantica's corporate level was $20.0 million, compared with $33.0 million as of December 31, 2023. Additionally, as of June 30, 2024, the Company had $266.3 million available under its Revolving Credit Facility ($378.1 million as of December 31, 2023) and therefore a total corporate liquidity of $286.3 million, compared with $411.1 million as of December 31, 2023.

As of June 30, 2024, net project debt⁶ was $3.83 billion, which remained stable compared with $3.90 billion as of December 31, 2023, while net corporate debt⁷ was $1.17 billion as of June 30, 2024, compared with $1.05 billion as of December 31, 2023. As of June 30, 2024, the net corporate debt / CAFD before corporate debt service ratio⁸ was 3.9x.

Dividend        

On July 31, 2024, the Board of Directors of Atlantica approved a dividend of $0.445 per share. This dividend is expected to be paid on September 16, 2024, to shareholders of record as of August 30, 2024.

Growth Update

Regarding growth, some of the developments that have taken place during the second quarter of 2024 include:

• In May 2024, we entered into a 10-year PPA for Caparacena, a 27.5 MWDC/22 MWAC project in Spain. Total investment is expected to be between $16 million and $18 million, with COD expected in early 2026.
  
  
• We continue growing our pipeline of assets under development, which includes as of today approximately 2.2⁹ GW of renewable energy and 6.3 GWh of storage. 24% of our pipeline is at an advanced development stage and 22% is expected to reach ready to build ("RTB") in 2024 or 2025.
  
  

Proposed Acquisition

On May 27, 2024, Atlantica entered into a definitive agreement pursuant to which California Buyer Limited, a private company incorporated under the laws of England and Wales controlled by Energy Capital Partners ("Bidco"), for the acquisition of 100% of its shares at $22 per share in cash, subject to the terms of such agreement (the "Proposed Acquisition"), concluding the strategic review. The Proposed Acquisition is to be completed pursuant to a scheme of arrangement under the U.K. Companies Act 2006 and is subject to, among other conditions, approval by Atlantica's shareholders of the scheme of arrangement, sanction of the Proposed Acquisition by the High Court of Justice of England and Wales, and regulatory approvals in different jurisdictions. The transaction is expected to close in the fourth quarter of 2024 or early first quarter of 2025. Upon the completion of the Proposed Acquisition, Atlantica will become a privately held company and its shares will no longer be listed on any public market.

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:

• they do not reflect our cash expenditures, future requirements for capital expenditures or contractual commitments;
• they do not reflect changes in, or cash requirements for, our working capital needs;
• they may not reflect the significant interest expense, or the cash requirements necessary, to service interest or principal payments, on our debts;
• 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;
• 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
• 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, financial expense (net), depreciation, amortization and impairment charges of entities included in the consolidated financial statements and including 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 as CAFD divided by the weighted average number of outstanding ordinary shares of the Company during the period (116,159,054 for the six-months ended on June 30, 2024, and 116,146,766 for the six-months ended on June 30, 2023).

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.

Our management believes CAFD and CAFD per share are relevant supplemental measurements 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 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 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 six-month period ended June 30, 2024 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 associates 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.

¹ CAFD per share is calculated by dividing CAFD for the period by the weighted average number of shares for the period.

² Represents total installed capacity in assets owned or consolidated for the six-month period ended June 30, 2024 and 2023, respectively, regardless of our percentage of ownership in each of the assets except for Vento II for which we have included our 49% interest.

³ Includes 49% of Vento II wind portfolio production. Includes curtailment in wind assets for which we receive compensation.

⁴ Includes 55 MWt corresponding to thermal capacity from Calgary District Heating. Capacity as of the six-month period ended June 2023 included 43 MW corresponding to our 30% share in Monterrey, sold in April 2024.

⁵ GWh produced includes 30% of the production from Monterrey until its sale in April 2024.

⁶ Net project debt is calculated as long-term project debt plus short-term project debt minus cash and cash equivalents at the consolidated project level.

⁷ Net corporate debt is calculated as long-term corporate debt plus short-term corporate debt minus cash and cash equivalents at Atlantica's corporate level.

⁸ Net corporate leverage is calculated as net corporate debt divided by midpoint 2024 CAFD guidance before corporate debt service. CAFD before corporate debt service is calculated as CAFD plus corporate debt interest paid by Atlantica.

⁹ Only includes projects estimated to be ready to build before or in 2030 of approximately 3.9 GW, 2.2 GW of renewable energy and 1.7 GW of storage (equivalent to 6.3 GWh). Capacity measured by multiplying the size of each project by  Atlantica's ownership. Potential expansions of transmission lines not included.

¹⁰"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.

¹¹ "Change in non-restricted cash at project level" excludes investments in assets under construction financed with cash at the project level.
