INFORMATION ON THE COMPANY

Opdenergy is a well-established and fully integrated independent producer of sustainable energy, focused on the production of solar photovoltaic ("PV") and onshore wind power, present in selected, stable and mainly fast-growing OECD renewable energy markets. In particular, Opdenergy is present and has pipeline projects in five markets in Europe (Spain, Italy, United Kingdom, France and Poland) and three markets in the Americas (United States, Chile and Mexico). Opdenergy's vertically integrated approach, with in-house expertise and integrated capabilities along the entire value chain, ensures invaluable understanding and control over the projects' development, structuring, financing, construction and operation and maintenance.

As of the date of this announcement, the Company's operating, ready for operation and under construction portfolio includes 13^[1] solar PV plants and one onshore wind plant, with an aggregate gross installed capacity of c.583.7 MW (including two plants in respect of which the Company owns a non-controlling interest) and an attributable installed capacity of c.468.3 MW. Approximately 104.3 MW of gross installed capacity correspond to Sol de los Andes, a wholly-owned solar PV plant located in Chile that is under construction, and the remaining gross installed capacity of c.479.4 MW (c.364 MW on an attributable basis) correspond to operating plants and plants which are ready for operation^[2]. In addition to this, the Company has an attractive growth profile with a pipeline with an aggregate gross capacity of c.9.4 GW, of which c.3.7 GW relates to projects in the most advanced stages (backlog and advanced stage projects) which the Company expects to undertake in the short to medium term.

The Offering represents the next step in Opdenergy's long-term development and ongoing transformation to become a large-scale geographically diversified independent power producer ("IPP"). Net proceeds from the primary component of the Offering will be fully dedicated to partially fund the equity portion of the capital expenditures associated with the development and construction of the c.3.7 GW related to pipeline projects in the most advanced stages, which includes c.907 MW of backlog projects, located in Spain and the United States, and c.2,781 MW of advanced stage projects. More than 93% of the backlog and advanced pipeline capacity is expected to reach a Ready to Build ("RTB") stage before the end of 2022, providing high visibility regarding the deployment in the short term of funds raised in the Offering.

Opdenergy has a clear vision and a well-defined strategy oriented towards the achievement of its medium-term targets while promoting a sustainable development. The Company is focused on OECD countries, creditworthy investment-grade off-takers and hard currency-denominated (or hard currency-linked) energy sales, which are supported mainly by long-term power purchase agreements ("PPAs") or other types of remuneration arrangements such as public remuneration plans with fixed or stabilized remuneration prices (or a combination thereof), for most of its power production, providing the Company with significant visibility and stability with respect to its future revenues.

Opdenergy has a proven track-record in executing renewable energy projects and delivering targets, having developed and overseen the commissioning of more than 800 MW in more than 70 different projects over the past 15 years, and having financed or transacted more than €2.0bn across different geographies.

The Company is led by a dynamic, highly qualified and experienced management team with over 100 years of combined experience in the sector, with a proven track-record identifying and executing new market and development opportunities and that has been directly responsible for the growth experienced by Opdenergy over the past few years.

Environmental, social and governance ("ESG") is at the core of Opdenergy's strategy and its key initiatives are oriented for the Company to play a very active role in the ESG transition, providing an opportunity to invest in an asset that will contribute positively and in an active manner to the transition towards a decarbonized world while targeting sustainable long-term returns. Opdenergy is also committed to maintaining best-in-class corporate governance practices to ensure a sound, long-term oriented governance.

"The Offering is a key milestone for Opdenergy in its path to become a large-scale IPP in Europe and the Americas. The company is currently at an ideal position benefiting from a robust balance sheet, a high quality and well-diversified operating portfolio and a tangible and attractive pipeline located in selected markets. The Offering proceeds will allow us to accelerate and fuel our ambitious business plan.

At Opdenergy we are fully committed to continue developing renewable energy projects in our markets, with a profitable and business-oriented strategy focusing on sustainability, and to continue delivering clean energy to our clients."

This Announcement includes forward-looking statements within the meaning of the securities laws of certain applicable jurisdictions. These forward-looking statements can be identified by the use of forward-looking terminology, including the terms "advanced stage", "backlog", "expects", "intends", "may", "pipeline", "potential", "should", "targets" and "will" as well as their negative or other variations or comparable terminology. These forward-looking statements include all matters that are not historical facts. They appear in a number of places throughout this Announcement and include statements regarding the Company's investment strategy and the Company's intentions, beliefs or current expectations concerning, among other things, the Company's financial performance, prospects, growth, pipeline, strategies and the industry in which the Company intends to operate.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. Forward-looking statements rely on a number of assumptions, including, among others, those related to the evolution of the industry, regulatory and economic trends and the Company's ability to successfully fund and carry out its growth plan, meet its targets and execute its pipeline. Such assumptions are inherently subject to significant business, operational, economic and other risks and uncertainties. You are hereby cautioned that forward-looking statements are not guarantees of future performance and that the Company's actual financial condition, results of operations and cash flows, size of its portfolio, and development of the industry in which it will operate, may differ materially from those made in or suggested by the forward-looking statements contained in this Announcement. In addition, even if the Company's financial condition, results of operations and cash flows, size of its portfolio, and development of the industry in which it will operate are consistent with the forward-looking statements contained in this Announcement, those results or developments may not be indicative of the Company's results or developments in subsequent periods and may be impacted by important factors. No representation or warranty is made that any forward-looking statement will come to pass. No one undertakes to publicly update or revise any such forward-looking statement.

The definition and classification of the pipeline of the Company, which comprises "Backlog", "Advanced Stage", "Early Stage" and "Identified Opportunities", may not necessarily be the same as that used by other companies engaged in similar businesses. As a result, the expected capacity of the Company's pipeline may not be comparable to the expected capacity of the pipeline reported by such other companies. In addition, given the dynamic nature of the pipeline, the pipeline is subject to change and certain projects classified under a certain pipeline category as identified above could be reclassified under another pipeline category or could cease to be pursued in the event that unexpected events occur.

The information, opinions and forward-looking statements contained in this release speak only as at its date and are subject to change without notice.

Information to distributors: Solely for the purposes of the product governance requirements contained within: (a) EU Directive 2014/65/EU on markets in financial instruments, as amended ("MiFID II"); (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the "MiFID II Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the Shares have been subject to a product approval process, which has determined that such Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the "Target Market Assessment"). Notwithstanding the Target Market Assessment, distributors should note that: the price of the Shares may decline and investors could lose all or part of their investment; the Shares offer no guaranteed income and no capital protection; and an investment in the Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Offering. Furthermore, it is noted that, notwithstanding the Target Market Assessment, the Managers will only engage with investors who meet the criteria of professional clients and eligible counterparties.

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Shares.

Each distributor is responsible for undertaking its own target market assessment in respect of the Shares and determining appropriate distribution channels.^[1] One of these 13 plants is our Puglia solar PV plant which consists of seven separate plants. The seven solar PV plants comprising Puglia are held through three different SPVs and are considered to be a single solar PV plant for management purposes.

^[2] Litre and Lingue, two of the Company's wholly-owned solar PV plants located in Chile with c.3.0 MW of gross installed capacity each, have already been constructed so for management purposes are considered ready for operation plants. However, these two plants are expected to reach full COD in June 2021.
