Operational KPIs

Production in the renewable energy portfolio decreased by 11.0% for the first quarter of 2024 compared with the first quarter of 2023 largely due to the unscheduled outage at Kaxu, where we have a 51% equity interest, that started in 2023. Kaxu restarted operations in mid-February 2024. Part of the damage and the business interruption is covered by our insurance policy, after a 60-day deductible. Production also decreased in Spain as a result of significantly lower solar radiation.

Production in our solar assets in U.S. increased by 16.1% due to higher availability of the storage system at Solana.

Efficient natural gas and heat assets, water assets and transmission lines, for which revenue is based on availability, continued at very high levels during the first quarter of 2024.

Liquidity and Debt

As of March 31, 2024, cash at Atlantica's corporate level was $46.9 million, compared with $33.0 million as of December 31, 2023. Additionally, as of March 31, 2024, the Company had $305.0 million available under its Revolving Credit Facility and therefore a total corporate liquidity of $351.9 million, compared with $411.1 million as of December 31, 2023.

As of March 31, 2024, net project debt⁹ remained stable at $3.90 billion, compared with $3.90 billion as of December 31, 2023, while net corporate debt¹⁰ was $1,126.8 million, compared with $1,051.7 million as of December 31, 2023. As of March 31, 2024, the net corporate debt / CAFD before corporate debt service ratio¹¹ was 3.8x.

Dividend

On May 7, 2024, the Board of Directors of Atlantica approved a dividend of $0.445 per share. This dividend is expected to be paid on June 14, 2024 to shareholders of record as of May 31, 2024.

Growth Update

Atlantica continued consolidating its growth strategy through its own development engine complemented by acquisitions.

In April 2024, Atlantica acquired the Imperial project, a 100 MW PV + storage project in Southern California. On May 6, 2024 the project entered into a 15-year PPA with an investment grade off-taker. Imperial is a well contracted project that benefits from synergies with the existing assets in California.
On March 22, 2024, the Company closed the acquisition of a 100% equity interest stake in two operating wind assets, with 32 MW combined capacity, located in Scotland, UK. The assets are regulated under the UK green attribute regulation. The investment was approximately $66 million and the assets currently do not have any project debt. These are Atlantica's first operating assets in the UK, and the expected return from these assets will be enhanced by the use of our existing net operating loss carryforwards in the UK in the upcoming years.
In April 2024, Chile PV 3 signed a 10-year PPA covering part of the production of the PV plant in operation and the 142 MWh battery storage expansion under construction. Under the PPA, the asset is expected to sell the electricity at a fixed price per MWh denominated in U.S. dollars and indexed to the US CPI. The PPA benefits from a higher price, given that the electricity is delivered during the night. Our investment is expected to be between $14 million and $15 million and COD is expected in 2024.
In May 2024, we approved a 27.5 MWDC/22 MWAC project in Spain for which we are in advanced negotiations to sign a PPA. Total investment is expected to be between $16 million and $18 million, with expected COD in early 2026.

Atlantica currently has a pipeline of projects under development of approximately 2.2 GW¹² of renewable energy and 6.0 GWh¹² of storage. This pipeline consists mostly of PV (47%), storage (41%) and wind (11%).

Capital Recycling

In April 2024, an entity where Atlantica holds 30% equity interest closed the sale of Monterrey as planned. Atlantica expects to receive approximately $43 million proceeds subject to final transaction costs, taxes, and ongoing discussions with the partner. There is an earn-out mechanism that could result in additional proceeds for Atlantica of up to approximately $7 million between 2026 and 2028.

Non-GAAP Financial Measures

This press release also includes certain non-GAAP financial measures, including Adjusted EBITDA, CAFD, CAFD per share and Enterprise Value to EBITDA. 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, Adjusted EBITDA and Enterprise Value to 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, CAFD per share and Enterprise Value to EBITDA 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, CAFD per share and Enterprise Value to EBITDA 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 three-months ended on March 31, 2024, and 116,140,187 for March 31, 2023).

We define enterprise value to EBITDA as an investment's enterprise value divided by its earnings before interest, taxes, depreciation, and amortization.

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, CAFD per share and Enterprise Value to EBITDA are widely used by other companies in the same industry.

Our management believes enterprise value to EBITDA is a useful valuation tool widely used by investors when evaluating transactions as it compares the investment's value to its earnings before interest, taxes, depreciation, and amortization.

Our management uses Adjusted EBITDA, CAFD, CAFD per share and Enterprise Value to EBITDA 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 period ended March 31, 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.
