A Word from the CEO

Dear Stakeholders,

I am delighted to present our latest Corporate Responsibility Report, which showcases our commitment to manage and operate our Company in a manner that helps preserve a world of opportunities for future generations. We continue our efforts across a broad range of ESG topics as part of our sustainability journey.

I am particularly pleased to see the high interest and engagement our team has expressed in our GreenMT initiative. Our new Purpose Statement, introduced in 2023, provides additional support and encouragement to align our daily actions with our Company Vision and Values.

In the past year, we made further strides toward our 2025 zero-waste-to-landfill goal; accelerated adoption of electric vehicles in our fleet; ramped up solar power and district heating capacities; and re-achieved our 100-percent-renewable-electricity-sourcing and carbon-neutral-operations targets. As a result, we remain on track to meet our 2030 science-based target for Scope 1

and 2 emissions reduction. However, we recognize that more effort is needed to achieve the corresponding target for our Scope 3 emissions, and we are fully committed to implementing the necessary programs to achieve our ambitious goals here as well.

We have also increased our efforts related to sustainable product design, supplier engagement, and transparency in our supply chain. Additionally, 2023 marked the launch of our refreshed Employer Brand and the expansion of our inclusive workplace program, fostering a diverse and inclusive corporate culture.

I am excited to share the details of our progress and ongoing ESG commitments in this report. We are proud and inspired by our work in these important areas and remain committed to continuous improvement, striving to create a lasting, positive impact for a better and healthier tomorrow.

Sincerely,

Patrick K. Kaltenbach

Sustainability Materiality Assessment

Our initial comprehensive materiality assessment dates to 2018 and was conducted by members of the Corporate Sustainability team, senior management, and various stakeholder representatives. During this assessment, we identified and prioritized the issues most relevant to us and our customers and shareholders, as bound within this report. To prioritize relevant topics, we identified our main economic, environmental, social, and governance impacts. We then viewed these in the context of the Company's culture, Corporate Vision and Values, and overall strategy to deliver sustainable shareholder and customer value over the long term.

Our assessment considered inputs we received from internal stakeholders-such as employees and representatives of different functional groups-and external stakeholders, including potential employees, customers, investors, suppliers, governments, regulators, and other interest groups. These various stakeholder groups all have an impact on the Company's success or are affected by the Company's actions and performance.

We have ongoing engagement with stakeholder groups: management has numerous interactions with the Board of Directors and with employees at all levels through regularly scheduled surveys, town hall meetings in local Units, training events, and other forums.

We regularly engage with our customers through our extensive sales and service interactions, customer surveys, and specific sustainability assessments that customers ask us to participate in. Our Supply Chain Management team is closely engaged with our suppliers on all relevant topics, including our expectations regarding sustainability in our supply chain. Our Investor Relations program ensures that we have a good sense of our shareholders' interests. We also actively monitor global trends and draw on consultants to understand current and emerging expectations of regulators, non-governmental organizations, and other interested parties.

As sustainability topics continue to evolve, we update the assessment to reflect changing and emerging topics and how these affect our Company and stakeholders. Based on best practice reviews and the stakeholder engagement described above, we updated this assessment in 2021, 2022, and 2023 to redefine and reprioritize topics where appropriate. We plan a further revision in 2024 to prepare for compliance with the new EU CSRD regulation.

We are confident our GreenMT strategy and updated goals are positioned to address all relevant ESG topics and help us deliver meaningful results.

Economic Performance

Financial Highlights

We operate a global business with sales that are diversified by region, product range, and customer type. We hold leading positions worldwide in all our markets thanks to the strength of our brand name and reputation, our comprehensive offering of innovative products and services, and the breadth and quality of our global sales and service network.

Our net sales were $3.8 billion for the year ended December 31, 2023, compared with $3.9 billion in 2022. Our local currency sales declined three percent following exceptional sales growth over the prior two years. Reduced market demand and a deteriorating economic environment led to an unprecedented sales decline during the second half of 2023. Despite these market challenges, our team demonstrated tremendous resilience and continued to execute extremely well.

Our net sales in 2023 derived 41 percent from the Americas, 32 percent from Asia and other countries, and 27 percent from Europe. Our customer base is also diversified by industry and by individual end-customer. We are a worldwide manufacturer with major facilities located in China, Switzerland, the United States, Germany, the United Kingdom, and Mexico.

Further information about our products and services, sales, operating results, cash flow, organization, and subsidiaries can be found in our Annual Report 2023, Item 1 (Business), Item 7 (Management's Discussion and Analysis of Financial Condition and Results of Operations), and Item 8 (Financial Statements and Supplementary Data).

Climate change highlights the need to accelerate actions and look beyond our operations to understand and limit impact on climate across our entire value chain. In 2021, we committed to near- and long-termCompany-wide greenhouse gas (GHG) emissions reductions, in line with the Science Based Targets initiative (SBTi). These targets are consistent with the latest climate science and the Paris Agreement goal of limiting global warming to 1.5°C above pre-industrial levels and were approved by SBTi in 2022 (for detailed description of our science-based targets covering Scopes 1, 2, and 3, see box on page 19).

The approval of these targets underlines our long-term commitment to taking meaningful action to limit climate change and supports credible collaboration with our suppliers and customers toward decarbonization (see also chapter "Responsible Supply Chain"). Our focus in 2023 was to continue our efforts to reduce Scope 1 and 2 emissions and to start activities aimed at reducing Scope 3 emissions in line with our climate strategy and road map.

In addition to reducing our GHG emissions, we continue our efforts to reduce the waste generated in our operations and to make progress toward our zero-waste-to-landfill target (less than five percent) by 2025.

The Corporate Sustainability team manages the GreenMT targets in these areas. Executive management members oversee projects in pursuit of the goals in their respective areas of responsibility. The individual Units manage initiatives relating to their specific business operations.

Assessment of Climate-Related Risks and Opportunities

In 2021, we broadened our analysis of climate-related risks and opportunities to incorporate the recommendations from the Task Force on Climate-Related Disclosure (TCFD) into

this report and our annual submission to the Carbon Disclosure Project (CDP). As part of our broader annual assessment of enterprise risks, the Head of Sustainability leads the assessment of climate-related risks and opportunities with active involvement from the Chief Executive Officer. Our annual enterprise risk assessment, conducted under the supervision of the Chief Financial Officer, includes the results of the climate-related assessment and is presented to the Board of Directors.

Business continuity planning is also a component of our enterprise risk management. Our Businesses Units update their business continuity plans every other year under the direction

The METTLER TOLEDO Climate Strategy

Absolute emissions cover Scopes 1, 2, and 3: Scope 1 covers direct emissions from owned or controlled sources; Scope 2 covers indirect emissions from the generation of purchased electricity, steam, heating, and cooling consumed by the reporting company; Scope 3 includes all other indirect emissions that occur in a company's value chain, such as upstream and downstream-related activities.

of the Chief Financial Officer's office and the Head of Supply Chain and IT. Where relevant, these plans assess and outline actions to mitigate and manage physical climate-related risks to our business locations. For information on risk oversight, also see chapter "Good Corporate Governance."

Our climate-related risks and opportunities cover the short-,medium-, and long-term and address regulatory, technological, legal, market, reputational, and physical risks. We include further details in our annual submission to CDP, accessible at www.cdp.net/en/scores.

Reducing Our Carbon Footprint

Reducing the carbon footprint of our operations has been at the core of the GreenMT Program since 2010, and we have made good progress since then. With our commitment to science- based targets in 2021, we further stepped up our ambition to reduce emissions from our operations (Scope 1 and 2). We also expanded the scope of our commitment to include GHG emission reductions in our value chain, upstream and downstream of our operations (Scope 3).

In support of these goals, we developed a comprehensive climate strategy with the initial focus on achieving our near-term targets by 2030. This strategy builds upon a range of key initiatives and measures, detailed below (also see box on page 20).

Strategy for Reducing Emissions from Operations (Scope 1 and 2)

The largest share-83percent-of our operations' GHG emissions stems from our sales and service vehicle fleet, consisting of more than 3,000 vehicles. We have been optimizing the efficiency of our vehicles for many years and aim for a fleet with more than 90 percent electric vehicles by 2030. We have country-specific targets for our Business Units' purchase and use of low-emission hybrid and electric vehicles, taking into account the availability of suitable vehicle types and charging infrastructure in their markets, as well as the vehicles' life cycle costs. In addition, we have implemented efficiency-raising fleet management practices and measures. Remote sales and service approaches are also leveraged where possible to reduce the use of vehicles altogether.

Refrigerants and fossil fuels used for stationary heating needs contribute to the remaining emissions from our operations. We aim to switch additional facilities to more modern HVAC systems, using refrigerants in lower volumes with lower GHG emissions. We also aim to switch more facilities to lower-emission and renewable energy options, including electric heat pumps, on-site renewable energy generation, or district heating. Projects for several of our facilities are currently being implemented or evaluated.

Energy efficiency projects continue to be implemented in our facilities, not only to reduce greenhouse gas emissions but also to increase operational resilience and reduce operational cost. Energy efficiency measures are part of our corporate operational excellence program, SternDrive. These measures are focused on optimizing manufacturing equipment and processes as well as facility infrastructure, including building insulation, lighting, heating, cooling (including refrigerants), and related control systems.

In addition to the above measures, we continue to purchase renewable electricity.

Strategy to Reduce Emissions from Upstream and Downstream Value Chain Activities (Scope 3)

Our responsibility extends beyond our direct operations and includes our Company's value chain emissions from upstream and downstream activities, also known as Scope 3 emissions.

Emissions from Purchased Goods and Services (Category 1) and Capital Goods (Category

1. together represent the largest share of our Scope 3 emissions. They are mainly driven by sourcing steel, metal parts, and other materials used in our products and the manufacturing of our products. A key priority for our teams in product development and supply chain
   is finding ways to reduce the amount-and the emissions impact-of metals and other materials used to make our products. This requires improved product and packaging designs and more efficient production processes. We are also engaging with suppliers to find alternative, low-emission materials or supply sources, such as materials with recycled content or produced with renewable energy.

Emissions from the Use of Sold Products (Category 11) are the second-largest contributor to our Scope 3 emissions. These emissions are largely driven by the electricity consumed by our products when used by customers. While most of our products have relatively low power consumption, they are sold in large numbers and remain in use by our customers

Our Approved Science-Based Emissions Reduction Targets

Near-Term Targets

Mettler-Toledo International Inc. commits to reduce absolute Scope 1 and 2 GHG emissions 70% by 2030 from a 2018 base year.

Mettler-Toledo International Inc. commits to reduce absolute Scope 3 GHG emissions from purchased goods and services, fuel and energy related activities, upstream transportation, business travel, employee commuting, and the use of sold products 30% by 2030 from a 2019 base year.

Long-Term / Net Zero Targets

Mettler-Toledo International Inc. commits to reduce absolute Scope 1 and 2 GHG emissions 90% by 2050 from a 2018 base year. Mettler-Toledo International Inc. commits to reduce absolute Scope 3 GHG emissions 90% by 2050 from a 2019 base year.

for many years, leading to sizeable aggregate emissions. We continue to focus on improving our products' energy efficiency during use, as well as training our customers to use energy- saving options where available. In addition, as our customers increase their use and sourcing of renewable electricity to reduce their own operations emissions, we can expect an additional reduction of our Category 11 emissions over time.

Emissions from Upstream and Downstream Transportation and Distribution (Categories 4 and 9) are the third-largest-although relatively smaller-contributor to our Scope 3 emissions. We have major manufacturing facilities located in China, Switzerland, the United States, Germany, the United Kingdom, and Mexico, and ship products worldwide to more than 140 countries. We continue to work with our logistics experts and transportation partners to improve the efficiency of our logistics network and to optimize routing and packing, as well as increase the share of low-emission transportation modes.

Business Travel (Category 6*) and Employee Commuting (Category 7) are two other relevant categories where we are making efforts to reduce emissions. Business travel to some extent is a necessity, given the global reach of our organization. Nevertheless, we continue to encourage our employees to minimize travel and leverage alternative web-based conferencing. For air travel we have a general policy to travel economy class. With more flexible and hybrid working models and the general shift to electric mobility, we expect further emissions reductions in the coming years. Wherever possible, employees are encouraged to use public transportation and bicycles when commuting to work.

• Category 6 also includes emissions related to the use of private vehicles to the extent covered by Company allowances or reimbursements.
