General information on the issuer and its share capital Management report for the nancial year ended 31 December 2021

4.3 Environmental information Aware of the interrelationship between the environment and the property sector, M.R.M. has undertaken to reduce its environmental footprint at the corporate level and across its asset portfolio. At the corporate level, M.R.M.’s head offices at 5, avenue Kléber in Paris are certified HQE (“High Environmental Quality”). The Company encourages its employees as users of the building to respect and protect the environment by sorting waste, using stationery sparingly, using alternative modes of commuting, conserving energy, and adopting other best practices. Across its asset portfolio, M.R.M. applies several voluntary and regulatory measures to limit the environmental impact of its properties. In its day-to-day operations M.R.M. implements formal measures such as the mandatory environmental appendix to all leases for retail property with a surface area of more than 2,000 Sqm. The appendix is meant to involve all parties in the value chain in workable and informative efforts to improve energy efficiency, reduce water and energy consumption, and limit waste production. The lessor and the lessee thus jointly draw up an assessment of the changes in the energy and environmental performance of the building and the leased premises in order to consider the actions to be implemented to improve energy effciency. M.R.M. wants to go beyond the regulatory obligation on this subject. Thus, since 2020, the Company has taken advantage of each new lease, amendment or lease renewal, regardless of its size, to include an environmental appendix. As of 31 December 2021, 70% of M.R.M.’s retail leases, representing 80% of leased space, thus had an environmental appendix. In 2019, only 7.5% of commercial leases had an environmental appendix. water consumption and waste production For several years M.R.M. has put concrete measures in place to reduce the amount of energy and water consumed and the amount of waste generated on its properties. 4.3.1 The environmental appendix, a key regulatory tool 4.3.2 Reduction in energy consumption,

In day-to-day operations they are applied via an action plan based on what works best for each type of retail property managed by M.R.M. Energy consumption • improvement of equipment and automation of heating, ventilation and air conditioning (“HVAC”) systems to achieve reduced energy consumption and a higher level of comfort. For example, by using Building management Systems (“BMS”) and modernising HVAC installations; • modernisation of equipment and automation of lighting systems resulting in substantial energy savings, notably through the installation of LED lighting systems and the installation of presence detectors; • conducting in 2021 of pre-audits on all buildings subject to the Tertiary Decree in order to control energy consumption and defne the investments to be made to achieve the regulatory objective of reducing the energy consumption of assets of more than 1,000 Sqm by 40% by 2030. The work plans for the buildings concerned have been adapted accordingly to ensure their regulatory compliance by 2030. To date, very encouraging results have already been recorded for the common areas of the buildings owned and managed by M.R.M., including: • Sud Canal shopping centre in Saint-Quentin-en-Yvelines: a 54.3% reduction in energy consumption over the period 2015-2021; • Les Halles du Beffroi shopping centre in Amiens: a 27.2% reduction in energy consumption over the period 2010-2021; • Le Passage du Palais shopping centre in Tours: a 38.8% reduction in energy consumption over the period 2015-2021; • Carré Vélizy mixed-use complex in Vélizy-Villacoublay: a 10.3% reduction in energy consumption over the period 2015-2021. The actions undertaken by M.R.M. since 2015 have significantly reduced the portfolio’s energy consumption (1) and, as can be seen from the graph below, the Company is now on the right trajectory to achieve the ambitious target of a reduction of 40% by 2030 set by the Tertiary Decree.

(1) Scope includes Sud Canal in Saint-Quentin-en-Yvelines, Les Halles du Beffroi in Amiens, Le Passage du Palais in Tours, Carré Vélizy in Vélizy-Villacoublay and Le Passage de la Réunion in Mulhouse.
