“Renewable energy is central to our transition to a low carbon economy. Powering a bright future is what we do at Sonnedix - developing, building and operating renewable energy that makes renewable power the affordable, reliable and sustainable choice for our customers.

“Powering a bright future is what we do at Sonnedix. This means that we’re committed to driving the energy transition at a pace and scale that meets the global ambitions established in the Paris Agreement. This work is urgent – we are continuing to see the escalating impacts of the climate emergency and know that the threats posed by the changing climate will have a serious negative impact on people and nature globally.

CHIEF EXECUTIVE OFFICER

While we continue to grow we recognise that we have an important responsibility to drive our own transition to a net zero business. This transition is integral to our vision for our company. The good news for our investors and other stakeholders is that it is also creating value, securing attractive financing, delivering on our customer needs and driving operational efficiencies.

Our focus on powering a bright future draws together everyone at Sonnedix and helps us build our talented and engaged team. Our approach to driving the energy transition, and decarbonising our business is at the heart of our culture.

We are proud of the progress we’re making but recognise that decarbonising any business is a long term journey and requires a joint effort. That’s why we’re focusing on integrating decarbonisation into the internal governance and systems to ensure that our business strategy remains integrated with our transition plan.

We know that we can’t do this alone - our success will rely on collaboration with our business partners and stakeholders, including our suppliers, to deliver the low carbon solutions we need. It also requires regulatory action to ensure a level playing field for all power companies and drive aligned action across our sector.

The engagement of our team is going to be critical to our decarbonisation effort. Thankfully the passion, expertise and capabilities we have as a team in delivering renewable solutions, will serve us well in our decarbonisation efforts.

At Sonnedix we are determined to be a leader in the transition to a low carbon economy. Our transition plan provides the road map for how we will deliver. I am proud to share it with you.”

GENERAL COUNSEL

We recognise that we can have an important positive impact in two areas – by delivering low carbon power to the market, and also by improving the sustainability of our business and decarbonising our own operations.

To deliver we must continue to accelerate the growth of our business and decouple commercial results from our operational carbon emissions. This is why decarbonisation is integral to our business strategy.

Decarbonisation is also fundamental to our business culture and values, and is shaped by our purpose to power a bright future. Our transition plan lays out the steps that we will take to decarbonise and the plan has helped us to establish the organisational structures we need to deliver across the business. It will allow us to ensure that we are decarbonising at a pace that aligns with the climate science. Decarbonising our business is an exciting process that will involve all our team, working together, with our stakeholders, towards our shared goals.

Climate Transition Plan

EXECUTIVE SUMMARY Welcome to Sonnedix’s Climate Transition Plan.

Sonnedix is a global renewable energy producer dedicated to accelerating the energy transition. Our climate transition plan describes our roadmap to achieve net-zero emissions by 2040, aligning with global climate targets and the Paris Agreement. This plan integrates decarbonisation into every aspect of our business, ensuring that our growth is powering a bright future. By leveraging innovation, digitalisation, and industry collaboration, we are committed to continuing on our path to deliver a resilient, low-carbon business and energy sector.

We have set ambitious targets to decarbonise our business. By 2030 we are targeting reducing our Scope 1 & 2 emissions by 60% and reducing our Scope 3 emission intensity by 40% and we aim to reach net zero by 2040.

Since the launch of our net zero target in 2021, Sonnedix has made notable strides in reducing emissions and embedding decarbonisation across our operations. Some of our key achievements include: • Signing The Climate Pledge, committing to net-zero carbon by 2040 and collaborating with peers across sectors to drive change.

• Increasing the purchase of green electricity to power our operations from 25% in 2021 to 64% in 2024 to drive a 23.5% reduction in absolute Scope 1 and 2 emissions.

• Increased engagement with key suppliers to align on decarbonisation objectives and drive future progress in Scope 3 reduction, with some initial progress already being made, including a 7% reduction in Scope 3 emissions intensity from 2023 to 2024.

Our transition plan is built to drive action and to tackle our biggest emission sources. It will adapt to integrate with changes to our business strategy. It is structured around six strategic action areas: 1

Decarbonised Supply Chain Partnering with suppliers to reduce embedded emissions in materials and logistics.

4

100% Renewable Power Ensuring our supply is sourced from clean power.

2

Low Carbon Development Using sustainable construction practices and alternative fuels.

5

Low Carbon Culture Embedding sustainability into decision-making.

3

Low Carbon Operations Reducing emissions from on-site activities and vehicle fleets.

6

Partnerships Collaborating with industry, policymakers, and investors to drive systemic change.

Our supply chain is a major driver of our carbon emissions, with our Scope 3 footprint typically accounting for over 95% of our emissions. Our purchase of PV panels currently accounts for the majority of our Scope 3 footprint. In the short term our priority is to drive our decarbonised supply chain and shift to 100% renewable power given the significant emission reduction opportunities. As we expand into battery energy storage solutions (BESS), and other new techologies, we are evaluating how this shift may reshape our emissions profile and are working closely with suppliers to understand the carbon footprint of these technologies.

To ensure the delivery of the transition plan and the continued alignment with our strategy we have established clear organisational forums, roles and responsibilities to oversee and drive implementation.

ACTING ON EMISSIONS IS URGENT The science is clear: climate change is accelerating, and we are running out of time to limit global temperature rise. Recent years have seen record-breaking heat and increasingly severe weather events, causing widespread disruption around the world. The World Meteorological Organization continues to report alarming trends, reinforcing the urgency of climate action.

To mitigate these risks, the Paris Agreement set a critical target of limiting global warming to 1.5°C above pre-industrial levels. Achieving this goal requires an economy-wide transition to low-carbon energy sources. Renewable energy plays a pivotal role in displacing fossil fuels and reducing carbon emissions. As energy demand continues to rise, expanding renewable capacity is essential to meeting global electricity needs sustainably.

We are committed to playing our part to help meet this target, both through growing our business to deliver more renewable power and through our transition plan and targets that describe how we will, in parallel, decarbonise our business.

Sonnedix is uniquely positioned to be a leader through this transition, delivering clean power at scale and advancing the technologies needed to make renewable energy even more efficient and accessible.

OUR BUSINESS STRATEGY AND TRANSITION PLAN As a global renewable energy producer, we are supporting the energy transition and are a key enabler of a decarbonised future.

Sonnedix’s transition plan is designed to integrate with, and support execution of, our business strategy to grow and optimise our operations (see www.sonnedix.com/offer). Decarbonising while driving business growth will deliver long-term and sustainable value for investors and the communities we serve.

Our transition to a net zero business will enable access to opportunity and is central to our operational excellence approach. Our transition plan provides an agile framework that will evolve with the business and couples a long term focus on delivering net zero by 2040 with flexibility to adapt to market needs. It guides how we integrate decarbonisation alongside our growth ambitions and vision for a low-carbon global energy system and will evolve with our business.

As most of our greenhouse gas emissions are generated outside of our direct control, there is a critical need to work closely with our suppliers to drive emissions reductions and ensure that every stage of our value chain aligns with our sustainability goals. By fostering these partnerships and building an ecosystem around clean energy, we will be able to contribute to a more resilient and low-carbon future for all.

Delivering will require us to have a long-term mindset and enduring commitment—working in collaboration with policymakers, peers, and other stakeholders to navigate and advance policies that support decarbonised supply chains, support renewable energy expansion and investment.

Sonnedix’s transition to net zero is not just an environmental imperative—it is a strategic opportunity. As renewable energy adoption accelerates globally, we are positioned for continued growth, resilience, and leadership in the sector. Our proactive approach to sustainability ensures regulatory compliance, enhances investor confidence, improves access to green and sustainable financings and strengthens our competitive edge in a rapidly evolving market.

OUR ROADMAP IN DETAIL Acting in six strategic actions will drive our transition to net zero. Each presents a unique opportunity to reduce our carbon footprint. We identify key emission reduction opportunities in each area and use reduction potential and degree of control to describe the impact of each opportunity. Reduction potential reflects by how much specific actions can lower emissions—classified as very high, high, medium, or low. Degrees of control describes Sonnedix’s ability to implement the actions: full control for (majority) owned assets, partial control where we can influence an action but cannot fully determine or implement it on our own, and limited control where we depend largely on external actors. Those labelled as ‘enablers’ are actions which do not directly contribute to emissions reduction, but they are essential for enabling the success of other emissions-reducing initiatives.

BUSINESS IMPLICATIONS OF TRANSITION The transition to a low-carbon economy presents both opportunities and investment considerations for Sonnedix. The transition plan is designed to align with and support our strategy for growth. It will provide opportunities to leverage financing arrangements that support and reward carbon emission reduction. It will help attract and retain customers who are aligning power purchasing with sustainability goals, and it will drive continued commercial advantage.

While some investments may be required over time, overall financial implications in the short-run are expected to be limited and can be mitigated through maximising the financial opportunities presented by the transition.

The immediate focus will be on opportunities that will have a high impact on emissions reduction with relatively low capital requirements. Strategic phasing of our implementation will further mitigate the financial impacts whilst ensuring we deliver against our long-term targets.

EVOLUTION OF SCOPE 1 AND 2 EMISSIONS (tCO2e)

2040

*vs 2023 baseline

SCOPE 1 AND 2 EMISSION DECARBONISATION PATHWAY For Scope 1 and 2, we have set ambitious near-term targets, aiming for a 60% reduction in absolute Scope 1 and 2 emissions by 2030 compared to the 2021 base year.

Our Scope 1 and 2 emissions consist mainly of emissions associated with fuel-used in Sonnedix-owned equipment and leased vehicles, refrigerants in air conditioning units and procured electricity for powering our operational assets.

Despite an ever-increasing number of assets in operation, and the resulting increase in production of electricity, our absolute Scope 1 and 2 emissions have reduced from our 2021 baseline by 23.5% as of 2024. In addition, our Scope 1 and 2 intensity has decreased by 65%. This has been driven by an increase in the share of green electricity procured from 26% of total electricity in 2021 to 64% in 2024.

We recognise that our emission reduction pathway will be influenced by the mix of technologies we deploy as our business grows.

SOLAR POWERED MAINTENANCE In 2024, we piloted replacing diesel-powered vegetation maintenance with autonomous, solar-powered robots on our PV plants in France. Following its success, we aim to expand this low-carbon solution, using both gridconnected and solar-only charging stations to further reduce emissions and operational costs. By replacing fossil fuel-powered machinery with this innovative, low-carbon solution, we are reducing emissions and promoting environmentally friendly practices on our sites — showcasing how technology can drive both sustainable practices and operational efficiencies.

SCOPE 3 EMISSION DECARBONISATION PATHWAY We have set an interim Scope 3 reduction target of 40% intensity reduction by 2030 and reaching net zero by 2040, against a 2023 baseline. In 2024, we began making progress, achieving a 7% reduction in intensity from 2023.

Our Scope 3 emissions are primarily driven by the procurement of key equipment for new sites, falling under the capital goods category, which currently represents by far the largest source. Other contributors include transportation and distribution, fuel and energy related activities, purchased goods and services, and several less material categories. Our net zero targets for Scope 3 are based on an intensity approach, which indexes our emissions against our procurement of equipment to monitor how we are decoupling our emissions from our business activities.

DRIVING EMISSION REDUCTION IN OUR SUPPLY CHAIN Decarbonising our supply chain is our greatest opportunity to reduce emissions, and we’re making meaningful strides in this transition. By consolidating our PV module procurement through framework agreements and prioritising suppliers with clear decarbonisation commitments, we are leveraging our purchasing power at scale to drive measurable impact and advance our long-term sustainability goals.

Our key solar suppliers have established decarbonisation plans and targets, making notable improvements to the embodied carbon in their products, with progress certified through product carbon footprints. These advancements reinforce the importance of supplier engagement in driving sustainability across our value chain.

To further support this transition, we hold dedicated decarbonisation workshops with our key suppliers, providing a platform to assess their progress, identify bottlenecks, and explore opportunities for joint action. By embedding carbon reduction into our procurement decisions and fostering deep engagement, we are supporting a resilient, low-carbon supply chain that accelerates our transition to net zero.

Climate Transition Plan

GOVERNANCE Our organisation and governance structure is intended to drive a culture of ownership across Sonnedix.

BOARD

Oversee decarbonisation

SENIOR LEADERSHIP TEAM (SLT)

Reports to the Board and is accountable for delivery, monitoring progress and integrating the transition plan fully with business strategy

ESG TEAM

Leads decarbonisation strategy, tracks and communicates performance and provides implementation support to relevant business areas, including employee and partner engagement and training

CLIMATE WORKING GROUP

Cross-functional collaboration of key function leads from Supply Chain, Construction, Operations, Finance, Commercial and Legal, responsible for monitoring and supporting implementation

REPORTING Structured and regular reporting will provide transparency, accountability, and continuous monitoring toward our decarbonisation goals.

Our reporting processes will include: • The SLT and Board will conduct annual reviews to assess progress and refine actions as needed.

• Quarterly Climate Working Group meetings will ensure targets remain on track and enable timely course correction.

• Annual carbon emission footprinting will allow us to track our progress in reducing emissions.

• External assurance will be secured on key carbon-related performance indicators to drive continuous improvement in data quality, supported by digital enhancements and integration with operational systems.

• Annual updates will be provided on our transition plan progress through our sustainability and annual reports.

TRANSITION PLAN APPROVAL The transition plan follows a structured approval process, ensuring alignment with business strategy, investment priorities, and risk management frameworks. The plan has been approved by the SLT and Board and progress against this plan will be reviewed annually (or more frequently as required) by both parties.

Our governance approach ensures that our climate transition plan remains integrated with the business strategy, supporting resilience, competitiveness, and long-term success.

BUILDING A LOW CARBON CULTURE As part of our transition plan, we have established a Climate Working Group to embed decarbonisation across all functions. This group drives emissions reduction by executing key initiatives, solving bottlenecks, and integrating sustainability into daily operations.

A crucial element of building a low-carbon culture is our employee engagement plan, which fosters education, transparent communication, collaboration, and recognition of achievements.

By embedding these principles and leveraging collective expertise, we drive progress while ensuring shared responsibility for emissions reduction.
