11 Quality, climate protection and resource conservation are the basis for our AimS product line. We are setting new standards in ecological and economic criteria and achieving excellent processing properties. Approx. 30% of the binder in AimS plasters and paints is made from renewable raw materials. Pine oil is used instead of crude oil. For a detached house with a facade area of approx. 200 m², the use of StoArmat Classic AimS / Stolit AimS / StoColor Lotusan AimS saves approx. 40 litres of crude oil. Conclusion: The more buildings that are coated with AimS products, the better it is for climate protection. AimS. The most sustainable product line of Sto 30/04/2025

Example: The EU Energy Performance of Buildings Directive was adopted by the Council of the European Union. The transposition into national law in conjunction with the goal of a climate- neutral building stock by 2045 will lead to an increase in refurbishment activities. The rate for energy-efficient refurbishment in the German building stock is currently 0.69% (as of 10/24). 41 Green Deal Possible opportunities and challenges Sources: Verband der Lack- und Druckfarbenindustrie VdL; Bundesverband energieeffiziente Gebäudehülle (BuVeG) Opportunities Challenges Example: In the ongoing discussions on the EU chemicals strategy the economic and technical/content-related effects on our products must be continuously reviewed with regard to future regulations and adjustments made if necessary. Political and geopolitical developments have pushed the issue of climate protection into the background at EU level. 30/04/2025
Page 42
42 Green Deal Status of the EU Energy Performance of Buildings Directive EU agreement on a standardised Energy Performance of Buildings Directive (EPBD) in April 2024. It must be transposed into national law by 29 May 2026. However, the EU was unable to agree on mandatory minimum standards (Minimum Efficiency Performance Standard, MEPS for short) for residential buildings. These have been introduced for non-residential buildings. Residential building: o Reduction in primry energy demand by 2030 (by 16 % or 20-22 % by 2035 compared to 2020). o Reduction of up to 55 % must come from the so-called "worst-performing buildings". Non-residential buildings: o Obligation to refurbish the 16 % with the poorest energy performance by 2030; 26 % with the poorest energy performance by 2035. In the area of residential buildings, the majority of savings must come from the buildings with the poorest energy performance – from a technical point of view, this effect cannot be achieved simply by changing the plant technology and therefore requires improvements to the building envelope.

Sto has great expertise when it comes to energy-efficient facade insulation for new buildings and refurbishment projects Building permits in the new construction segment have declined significantly in recent years. Permits (detached house/semi- detached house) have been rising slightly since autumn 2024. At the same time, there was and still is a high need for refurbishment of existing buildings. To achieve the climate targets set, a refurbishment rate of 1.9% would be necessary (currently 0.67%). Legislators are called upon to set the framework for sustainable investments in the building sector Do not increase technical requirements any further Reduce bureaucracy Targeted funding 43 Building stock in Germany Sources: ThePioneer & Handelsblatt, Media Pioneer Publishing AG, 2023; Bundesverband energieeffiziente Gebäudehülle (BuVeG); Statistsches Bundesamt 30/04/2025

Sto Group 2023 Forecasted turnover and earnings targets achieved 30/04/2025 About the title image Steimle Architekten realised a striking residential and office ensemble with three point buildings linked by a shared ground floor in Ludwigsburg city centre. The design of the new KfW -55 buildings (energy efficiency class according to German investment and development bank) is based on the surrounding aged clinker brick buildings from the 'Gründerzeit’ (time period between the mid 19th century and 1914). Rough, irregularly shaped hand-laid brick slips (StoBrick) were used on two different facade systems – the StoTherm Mineral external wall insulation system and the StoVentec C ventilated rainscreen cladding system. The sloping surface was achieved with a special construction and a rainscreen cladding facade from Sto. In the window openings with their reveal chamfers, the sloping motif is repeated a second time in the facade and gives the architecture a characteristic expression. The plinth storey was designed with the StoSignature Fine 20 surface technique. It combines the organic Stolit render finish with a sanded fine render (Stolit Milano[R-Markenzeichen]).

72 30/04/2025 Outlook Outlook for 2025 as a whole * The forecast is based on average weather conditions and an economic development in line with expectations in Sto's key markets as well as a mainly stable euro exchange rate. Another key assumption is that geopolitical tensions such as the Russia- Ukraine conflict or the Middle East conflict will not cause any significant impairment of demand in the markets relevant to Sto and that there will be no restrictions in the conduct of business activities or the supply of raw materials, bought-in products and energy. Further significant amendments to general conditions, such as the introduction of tariffs by the US government, which could have a considerable impact on Sto’s key trading partners and thus above all an indirect impact on the Sto Group, cannot be reliably calculated and have not been taken into account. The risks and opportunities for 2025 fiscal year are described in detail in the Management report of the Annual Report 2024.
