November 10, 2021 – Atlantica Sustainable Infrastructure plc (NASDAQ:AY) ("Atlantica" or the "Company") today reported its financial results for the first nine months of 2021. Revenue was $940.4 million, a 22.3% increase compared with the first nine months of 2020. On a comparable basis¹, the increase in revenue was 8.4%. Adjusted EBITDA including unconsolidated affiliates increased by 2.1% up to $634.1 million. Growth in revenue and Adjusted EBITDA including unconsolidated affiliates, resulted mainly from the recent investments in new assets, higher production in our renewable energy business and foreign exchange differences, and was partially offset by an accounting adjustment with no cash impact in the current period caused by higher electricity market prices in Spain. Cash Available for Distribution was $168.5 million, a 12.9% increase compared with $149.2 million in the first nine months of 2020. CAFD per share² was $1.52, a 3.6% increase compared to the same period of the previous year.

Production in the renewable energy portfolio increased by 32.7% for the first nine months of 2021 compared with the first nine months of 2020 mainly thanks to the contribution of recent investments, higher output at Kaxu as well as better solar radiation in Spain. Our wind assets in the United States and South America had a lower production than expected due to lower wind resources.

In our efficient natural gas and heat and transmission lines segments, where revenue is based on availability, we maintained very high availability levels. In water, the decrease in availability was largely due to the installation of some new safety-related equipment during the first quarter and maintenance works in the third quarter.

Liquidity and Debt

As of September 30, 2021, cash at Atlantica's corporate level was $78.6 million, compared with $335.2 million as of December 31, 2020. Additionally, as of September 30, 2021, the Company had $425.0 million available under its Revolving Credit Facility and therefore total corporate liquidity of $503.6 million, compared with $750.2 million as of December 31, 2020.

As of September 30, 2021, net project debt⁸ was $4.59 billion, compared with $4.70 billion as of December 31, 2020, while net corporate debt⁹ was $951.5 million, compared with $658.5 million as of December 31, 2020. The net corporate debt / CAFD pre-corporate debt service ratio¹⁰ was 3.5x as of September 30, 2021. As of September 30, 2021, our average corporate debt maturity stands at approximately 5.5 years.

Dividend

On November 9, 2021, the Board of Directors of Atlantica approved a dividend of $0.435 per share. This dividend is expected to be paid on December 15, 2021 to shareholders of record as of November 30, 2021.

Accretive Growth Strategy

During the first nine months of 2021, Atlantica continued with its growth plan. 2021 has been a strong year in terms of investments.

With the acquisitions of Coso and Vento II, Atlantica invested close to $370 million in renewable assets in operation in North America.
The Company also invested in a photovoltaic (PV) plant through its renewable energy platform in Chile earlier this year and expects to close the acquisition of La Sierpe, another PV asset in South America in the fourth quarter of 2021.
Furthermore, in the third quarter of 2021, the Company closed the acquisition of two PV assets in Italy, the first investment in this country.

If we consider other smaller investments already executed during the year, total investments closed so far in 2021 total $465 million, well above the $300 million annual target that we provided at the beginning of 2021.

Continued Strong Progress on ESG

Atlantica continues to achieve new milestones within its strong commitment to ESG.

At the COP 26, the United Nations Climate Change conference held in Glasgow this November, Atlantica announced an ambitious greenhouse gas (GHG) objective approved by the Science Based Targets initiative (SBTi). Atlantica targets to reduce Scope 1 and 2 GHG emissions per kWh by 70% by 2035 from a 2020 base year¹¹. Targets are considered ‘science-based' if they are in line with the latest levels recommended by climate science to meet the goals set out in the Paris Agreement to limit global warming to "well-below 2ºC".
In addition, Atlantica has been selected amongst the inaugural recipients of the Terra Carta Seal, launched by His Royal Highness the Prince of Wales through the Sustainable Markets Initiative (SMI). The Terra Carta Seal recognizes companies which are demonstrating their commitment to, and momentum towards, the creation of genuinely sustainable markets. It is awarded to companies whose ambitions are aligned with those of the Terra Carta, a recovery plan for Nature, People and Planet, launched in January 2021.

2021 Guidance

Atlantica expects to close the year 2021 with a CAFD in the range of the guidance provided in March 2021, which is between $220 million and $240 million.

The Company expects to achieve an Adjusted EBITDA including unconsolidated affiliates at or slightly below the low end of its guidance, which was $820 million, mainly due to the accounting adjustment to revenue caused by high electricity market prices in Spain. The accounting adjustment would not have a cash impact in 2021.

Details of the Results Presentation Conference

Atlantica's CEO, Santiago Seage, and CFO, Francisco Martinez-Davis, will hold a conference call and a webcast on Wednesday, November 10, 2021, at 8:30 am (New York time).

In order to access the conference call participants should dial: + 1-631-510-7495 (US), +44 (0) 844-571-8892 (UK) or +1-866-992-6802 (Canada), followed by the confirmation code 8186973. Atlantica advises participants to access the conference call at least 20 minutes in advance.

The senior management team will hold meetings with investors during the month of November at the RBC Capital Markets Midstream and Energy Infrastructure Conference.

Non-GAAP Financial Measures

This press release also includes certain non-GAAP financial measures, including Adjusted EBITDA including unconsolidated affiliates, Adjusted EBITDA including unconsolidated affiliates as a percentage of revenues (margin), 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 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 including unconsolidated affiliates) 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 including unconsolidated affiliates as profit/(loss) for the period attributable to the Company, after adding back loss/(profit) attributable to non-controlling interest, income tax, share of profit/(loss) of associates carried under the equity method, finance expense net, depreciation, amortization and impairment charges. 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 (110,749,202 for the nine months ended on September 30, 2021, and 101,878,667 for 2020).

Our management believes Adjusted EBITDA including unconsolidated affiliates, 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. 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 including unconsolidated affiliates 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.
