Avantor, Inc.

Avantor's Science for Goodness sustainability strategy is a key part of our commitment to deliver long-term value to our customers, associates, suppliers, communities and stockholders. This platform aims to foster an inclusive work

environment, promote innovation for a sustainable future, support and strengthen our communities, and add value to Avantor. We are embedding sustainability throughout our business ensuring our everyday actions generate positive impact.

Science for Goodness: Our Approach to Sustainability.

Our sustainability commitment is led by our Executive Leadership Team and Board of Directors, and is driven by our global associate population. Our impact and purpose are centered on four key commitment pillars – People & Culture, Innovation & Environment, Community Engagement and Governance & Integrity that are aligned with the following UN Sustainable Development Goals: Good Health & Wellbeing, Quality Education, Industry, Innovation and Infrastructure, Reduced Inequalities, and Responsible Consumption and Production.

People and culture: We empower people to create a better world. Our core values of innovation, customer centricity, accountability, respect and excellence ("ICARE") are embedded within our continuous improvement processes to advance best practices in all we do. At Avantor, goodness comes from how we innovate, collaborate, connect and inspire each other to help build a sustainable future for all.

Innovation and environment: Grounded in collaboration and driven by our customer relationships, our approach to innovation – from scientific discovery to commercial scale – aims to create value for our associates, investors, customers, suppliers and communities at large. As our customers look to us to support their sustainability goals, we are embedding sustainable practices throughout our operations by addressing our greenhouse gas emissions, energy consumption, water usage, and waste, as well as through providing environmentally preferable products for our customers.

While relentlessly focusing on advancing life-changing science, Avantor recognizes its shared responsibility and is committed to addressing key environmental sustainability issues. In 2024, we continued to make progress to reduce our Scope 1 (direct) and Scope 2 (indirect) greenhouse gas ("GHG") emissions, and added Scope 3 emissions tracking to our program. The cross-functional Environmental Task Force, created in 2022, continues to lead this effort whereby Avantor prioritizes investments that will optimize our operational processes, meet our productivity guidelines and lower our operating emissions.

Community engagement: Avantor’s philanthropic initiatives generate positive, enduring impact on the planet, society and the communities where we work and live. We do this through grants from the Avantor Foundation, a private charitable foundation funded by Avantor, and by encouraging our associates to give back through volunteerism, collection drives and other means. Our giving and volunteer efforts focus on increasing Science, Technology, Engineering and Math (STEM) education programs for underserved high school students, providing equitable access to quality healthcare and demonstrating environmental stewardship where Avantor has a presence. In 2024, we once again increased our community impact and programming. Contributing factors include the expansion of our Volunteer Time Off benefit to four additional countries and hosting our second annual Month of Giving campaign.

Governance and integrity: We are committed to practicing responsible corporate governance, adhering to best practices, proactively identifying opportunities for process improvement, and elevating valued partnerships, both internally and externally. This commitment encompasses conducting business in full compliance with applicable laws and regulations, maintaining a high degree of internal conduct and communication standards through our Code of Ethics and Conduct and other internal policies. Through the end of 2024, we have enrolled 55% of our suppliers by spend into our Responsible Supplier Program which is the vehicle to ensure Avantor suppliers are well-positioned to help us meet the sustainability challenges of the future.

Management and Board Oversight

Avantor’s executive leadership team, comprised of Avantor’s CEO, CFO and executives from across the company, oversee Avantor’s efforts to integrate sustainability and corporate responsibility into our strategic planning, risk management and reporting. Day-to-day responsibility for Avantor’s Sustainability Program resides with a cross-functional representation of leaders headed by the Vice President, Global Sustainability and Impact, who meet regularly to review progress and provide recommendations to the executive team.

At the Board level, the Board as a whole and through the Nominating and Governance Committee, oversees sustainability and corporate responsibility. The Nominating and Governance Committee and Board received regular updates throughout 2024 on the Company’s sustainability reporting and progress against goals under its four sustainability pillars. The full Board received an annual briefing from an outside consultant on the evolving climate and reporting landscape – including what investors expect. Our management team also briefs the Board regularly on the main priorities and feedback from key customers and other stakeholders. The Board has fully supported management's efforts to enhance our energy and emission practices.

Other Board committees also conduct detailed reviews on key corporate sustainability topics; for example, our Compensation and Human Resources Committee oversees the Company’s talent, culture, compensation structure and compensation programs. Throughout the year, we report on CEO and overall leadership succession, review talent/compensation philosophies, provide updates on human capital KPIs and evaluate plan-linkage of sustainability metrics to our annual bonus plan. Our Audit and Finance Committee assists the Board in monitoring cybersecurity risk. We continue to maintain best-in-class governance provisions, including robust stockholder rights, and established a responsible supplier code of conduct that outlines our expectations for suppliers on topics such as sustainability, human rights and compliance.

Reporting

We released our annual Avantor Corporate Sustainability Report in June 2024 that outlines progress made on our four sustainability pillars and highlights how our associates are involved in helping to advance Science for Goodness. Our annual Corporate Sustainability Reports continue to include the Sustainability Accounting Standards Board’s (SASB) reporting disclosure for the Medical Equipment & Supplies, Biotechnology & Pharmaceuticals and Chemicals industries, and the Task Force for Climate Disclosure. We also continue to disclose climate strategies and metrics through CDP (formerly Carbon Disclosure Project).
