Sustainability Report

Dear Shareholders,

I am honored to present the 2025 Sustainability Report, which highlights Belimo's commitment to healthier, more comfortable indoor environments and reduced energy consumption. Sustainability remains a strategic priority embedded in our mission and reflected in innovative products that enhance building energy efficiency worldwide.

Improving indoor air quality is central to our business, whether equipping new buildings with innovative field devices or deploying them in RetroFIT+ projects. We closely monitor the positive impact of our products and are constantly seeking to improve the wellbeing of building occupants. This dedication is grounded in our culture of credibility, built on trust, expertise, and responsibility, which serves as the foundation of our value creation model.

Belimo operates with the highest level of integrity, supported by cultural diversity, equal treatment, an inclusive workplace, and a firm commitment to preventing discrimination. In 2025, Belimo further advanced its diversity, equity, and inclusion efforts through several successful initiatives, increasing the Company’s visibility among female engineers and contributing to a higher number of women in leadership positions. Belimo also reinforced its commitment to pay equity by regularly reviewing compensation across all roles and regions.

Our sustainability goals drive us towards the decarbonization of our entire value chain – from purchased materials, and transportation, to manufacturing and operational waste in our own operations, and the use-phase of our products. Recognizing the urgency to minimize its environmental impact, Belimo joined the Science Based Targets initiative. In 2025, the Science Based Targets initiative reviewed and validated our near-term and net-zero emissions reduction targets for Scope 1, 2, and 3. This ensures that our decarbonization trajectory is aligned with the Paris Agreement's 1.5°C mitigation pathway, thereby highlighting the credibility and ambition of our climate targets.

Belimo may become subject to the EU’s Corporate Sustainability Reporting Directive – and consequently the European Sustainability Reporting Standards – as early as 2028, given its subsidiaries in the EMEA region. To ensure compliance early on, we undertook our first double materiality assessment in 2024, engaging key stakeholders – including the financial community, academia, associations, suppliers, and customers.

This Sustainability Report has been prepared in accordance with the Global Reporting Initiative Standards and selected disclosures have been reviewed by a third party to ensure completeness and accuracy of reporting.

Climate-related risks and opportunities are integrated in the annual Enterprise Risk Management process in accordance with the IFRS S1 and S2 standards, and they are aligned with the recommendations of the Task Force on Climate-related Financial Disclosures.

Our ongoing sustainability efforts contribute to the United Nations Sustainable Development Goals, and we are proud to uphold the principles of the UN Global Compact. To ensure compliance with best global practices, this Sustainability Report follows the Global Reporting Initiative standards. In parallel, we adapt our processes for future alignment with European Sustainability Reporting Standards requirements by expanding the reporting scope and the set of sustainability indicators.

These initiatives form part of Belimo’s broader sustainability strategy, which includes a comprehensive climate strategy with long-term decarbonization goals, alignment with internationally recognized standards and best practices, and readiness for future sustainability reporting requirements under the European Sustainability Reporting Standards. Belimo remains committed to making a positive impact on the environment, society, and governance by focusing on the topics most relevant to our stakeholders.

We thank all of our valued stakeholders for their continued support as we strive to achieve our sustainability targets.

Sincerely,
