Corporate governance

Oversight of Board of Directors

The Board of Directors of Rieter Holding Ltd. defines the company’s sustainability strategy at the Group level and sets objectives and priorities. Climate-related matters are embedded in Rieter Group's sustainability strategy. The Board of Directors has committed to addressing sustainability aspects, including climate-related issues, separately in three Board meetings each year. In 2025, this took place as planned in three meetings.

In 2024, the Board of Directors mandated the Group Executive Committee to establish a Sustainability Committee to develop the conceptual framework for the implementation of the sustainability strategy. Climate-related matters are embedded in these activities. The Committee includes leaders from the areas of supply chain, finance, legal, occupational safety and environmental protection, communications, human resources and sustainability. The Committee meets every two months to assess progress on sustainability initiatives. Under the leadership of the CEO of Rieter, the Committee met six times in 2025.

For more information on Board oversight, see the Sustainability Strategy section under Sustainability Governance.

Role of the Group Executive Committee

The Group Executive Committee is responsible for implementing the sustainability strategy at the operational level and for monitoring the achievement of sustainability goals. Climate-related matters are embedded in Rieter’s sustainability strategy and supported by corresponding goals. The Group Executive Committee has committed itself to address sustainability issues, including climate-related matters, in at least three Executive Committee Meetings. This took place as planned three times in 2025.

Strategy

Climate-related risks and opportunities

Rieter continuously identifies, monitors and manages climate-related risks and opportunities on a short-term (one year), medium-term (two to five years) and long-term (more than five years) basis. Two categories of climate-related risks and opportunities are differentiated: physical risks and opportunities associated with changing climatic conditions, and risks and opportunities associated with the transition to a low-carbon economy. The risks and opportunities identified by Rieter are summarized in the subsequent table.

Impact of climate-related risks and opportunities

Physical risks and opportunities include on one hand the effects of short-term, acute extreme weather events such as severe storms, heavy rain/flooding, wildfires and landslides. These can result in damage to the Group’s own infrastructure or disruptions in the supply chain, such as supply bottlenecks, or can significantly impact logistics due to disrupted transportation routes. On the other hand, the physical risks and opportunities also include the longer-term chronic, localized effects of climate change. These include the effects of rising average temperatures and/or sea levels, as well as increased and longer periods of heat and drought.

Transitional risks arise from new political, legal, technological, social, market and reputational developments triggered by climate change. These include the pricing of CO₂, compliance with new climate change legislation and regulations to protect the climate, the reliability of energy supply in the context of the energy transition, changing customer preferences towards sustainable products, the development of sustainable technologies, and the redirection of capital flows towards sustainable investments.

The climate-related risks and opportunities identified by Rieter, their impact on the Group and the measures taken are described in the following table. A distinction is made between the impacts, risks and opportunities for in-house production (own environmental footprint) and for Rieter’s customers and suppliers (supply chain).

Physical risks and opportunities

Type	Impacts on Rieter: risks and opportunities	Measures
Acute
Extreme weather events (storms, flooding, landslides, wildfires) and earthquakes	Risks Own production Damage to the Group’s own infrastructure can result in unforeseen costs for repairs or replacements, or in production downtime and the associated loss of sales. Supply chain Supply bottlenecks due to damage at suppliers can result in production downtime and the associated loss of sales. Disruptions to sea and road transportation routes can result in higher costs due to rescheduling and delays. Opportunities Supply chain Rieter can assist its customers in assessing the damage and provide appropriate advice. Rieter can expedite repairs and inspections of damaged machines. Rieter can assist its customers in restoring production capacity.	Risk mitigation and exploitation of opportunities Own production Rieter ensures that dealing with extreme weather events is integrated into the contingency plan at all sites. Rieter maintains its critical infrastructure on a regular basis. Own production and supply chain To ensure the resilience and stable management of the supply chain, Rieter conducts regular risk assessments in accordance with an annual audit plan.
Chronic
Long-term local impacts (rising average temperature and sea level, more frequent and prolonged heat waves)	Risks Own production and supply chain Rising average temperatures can lead to higher energy requirements for cooling machines and workplaces in the summer. This can result in higher operating and capital costs and increased greenhouse gas (GHG) emissions. Rising sea levels may lead to the relocation of the Group’s own sites, such as in the Netherlands, as well as the relocation of suppliers’ and customers’ sites at or near sea level. This can result in higher operating and capital costs. In addition, supply bottlenecks may occur, which could have a negative impact on the Group’s sales. More frequent and longer heat waves can have a negative impact on the availability and quality of cotton, resulting in higher procurement costs and/or a shortage of cotton. In addition, heat waves can affect the availability and quality of drinking water and water levels needed for cotton production. Opportunities Own production and supply chain Rising average temperatures reduce the need for heating in winter. This can result in cost savings and reduced GHG emissions. A shortage of cotton on the world market may lead to increased demand for resource-efficient technologies and Rieter’s recycling solutions. Rieter’s technological expertise can help to develop new fiber types and further expand the company’s market leadership.	Risk mitigation and exploitation of opportunities Own production Regular assessment of chronic physical risks as part of the risk management system ensures resource efficiency, energy-efficient production, and maintenance of business continuity. Supply chain In addition, annual supplier risk assessments increase resilience by requiring diversification of the supplier base and identifying alternative transportation routes.
Biodiversity	Risks Own production and supply chain Increasing textile consumption has a negative impact on biodiversity due to resource intensity, the global supply chain and water intensity during the use phase. Opportunities Own production and supply chain Collaboration with various stakeholders in the industry strengthens the company’s ability to innovate, which in turn underscores Rieter’s leading role in sustainability. Supply chain If demand for sustainable products increases, Rieter is able to supply the appropriate technology.

Strategy resilience

The faster climate change progresses, the greater the impact of physical risks. To slow global warming accordingly, various measures are needed, which tend to lead to higher transition risks.

In a net-zero scenario, transition risks such as policy, regulatory and legal risks dominate.

Physical risks, such as extreme weather events, storms, hurricanes and rising sea levels dominate in a low decarbonization and adaptation scenario.

Risk management

Process to identify and assess climate-related risks

The climate-related risks and opportunities described in the table were identified by the Corporate Risk and Insurance Management department and reviewed and confirmed by the Sustainability Committee. They were then integrated into existing workflows in all three divisions.

Processes for managing climate-related risks

The measures identified to manage climate-related risks are described in the table.

Integration of processes to identify, assess and manage climate-related risks

Rieter has implemented a comprehensive risk management system that also identifies and manages non-financial risks. The risk management process is governed by the “Rieter Risk Management System” directive. This directive defines the procedures for identifying, reporting and handling risks, the criteria for qualitative and quantitative risk assessment, and the thresholds for reporting identified risks to the appropriate management levels.

Environmental risks are also evaluated and assessed as part of the risk assessment. As a result, various areas for action have already been identified and risk mitigation measures have been implemented. At least once a year, the risks are assessed in a workshop led by the Head of Legal Services (General Counsel) and documented in a report to the Board of Directors.

Key figures and goals

Key figures to assess climate-related risks and opportunities

Rieter assesses its environmental footprint using the following key figures:

greenhouse gas (GHG) emissions scope 1, scope 2 and partially scope 3,
energy consumption and share of energy consumption in renewable sources,
amount of waste generated during production and recycling rate as well as
water withdrawal.

Water withdrawal in production has a smaller impact on Rieter’s environmental footprint than GHG emissions, energy consumption and waste volumes, as most processes are not water intensive. Rieter’s current materiality analysis therefore does not identify water as a topic of high relevance, and reporting on this topic will be discontinued after 2025. Nevertheless, Rieter continues to promote responsible water management throughout its operations.

GHG emissions and associated risks

Scope 1 GHG emissions include direct greenhouse gas emissions from sources owned or controlled by Rieter, such as emissions from a gas-powered heating system or a gasoline-powered company-owned vehicle.

Scope 2 GHG emissions include indirect GHG emissions from the generation of acquired or received electricity, steam, heat or cooling, such as emissions from purchased electricity.

Scope 3 GHG emissions include all indirect GHG emissions not covered by scope 2 that occur in Rieter’s upstream and downstream value chain.

Climate-related risks and opportunities

To reduce its own environmental footprint, Rieter has set targets in the following climate-related areas for the financial year 2025:

Reduction of energy consumption at own locations,
reduction of GHG emissions (scope 1 and scope 2),
reduction of waste in the production of Rieter spinning systems and
reduction of water withdrawal.
