(4) RISK MANAGEMENT - RISK OF CLIMATE CHANGE ON STRABAG'S BUSINESS CLIMATE CHANGE More frequent and extreme climate events have made environmental risks more significant for STRABAG's activities, notably storms, floods, heat and rockslides or even ground movements can affect buildings and infrastructure as well as the safety and health of our employees Climate change also implies an increasing scarcity and security of supply of raw materials, and this despite our own production and supply of building materials, notably minerals, rare metals, fossil fuels but also water, timber and plastics POSSIBLE IMPACT • Material damage to building construction, installation and equipment • Health and safety conditions for our employees • Financial impact from higher costs of raw materials but also repair and maintenance, operational losses and construction delays • Regulatory or market changes leading to lower project profitability • Reputational damage in case of quality deficiencies and/or missed delivery deadlines 27 Investor Presentation November 2021 STRABAG SOCIETAS EUROPAEA
