General information on the issuer and its share capital

Consolidated financial statements for the financial year ended 31 December 2022

The acquisition by M.R.M. concerns 44 stores covering a surface area of 3,125 m 2 . The site welcomed 3.1 million visitors in 2022. A financing structure that keeps M.R.M.’s net debt under control The acquisition was carried out through contributions in kind and disposals by Altarea to two M.R.M. subsidiaries. It was remunerated partly in cash for a total amount of €68.9 million and partly by the issue of new M.R.M. shares for a total amount of €21 million, the latter taking the form of an increase in M.R.M.’s share capital reserved for Altarea at an issue price corresponding to its replacement NAV as of 30 June 2022, namely €48.92 per share. The cash payment of €68.9 million resulted from: • a new bank loan of €42 million; • a current account advance from SCOR SE in the amount of €25 million; • M.R.M.’s available cash. In a second step, M.R.M. carried out a capital increase in cash with maintenance of the preferential subscription rights in the amount of €29 million at a unit subscription price equal to its replacement NAV as of 30 June 2022, namely €48.92 per share: • SCOR SE subscribed in the amount of €25 million by capitalisation of the aforementioned current account advance; • Altarea subscribed by exercising its preferential subscription rights in the amount of €4 million. In the end, the transaction resulted in two capital increases of M.R.M. for a total amount of €50 million subscribed by SCOR SE for €25 million and by Altarea for €25 million. This financing structure allows M.R.M. to maintain a net LTV ratio of less than 45%: 43.6% as of 31 December 2022 compared to 40.0% a year earlier. Strengthening M.R.M.’s shareholding structure and governance Following the issue of new shares related to the two share capital increases carried out as part of the Acquisition Transaction, SCOR SE and Altarea now hold respective stakes of 56.63% and 15.94%. In addition, Altarea was appointed as a director by the Combined General Meeting of 16 November 2022. Since that date, M.R.M.’s Board of directors has been composed of: • François de Varenne, Chairman of the Board of directors and director;

• SCOR SE, director, represented by Karina Lelièvre; • Karine Trébaticky, director; • Altarea, director, represented by Rodrigo Clare; • Brigitte Gauthier-Darcet, independent director; and • Valérie Ohannessian, independent director. Rental management and rentals In 2022, the rental business was dynamic with thirteen new leases or renewals of leases signed, covering a total of 4,900 m 2 and representing annual rents of €0.9 million. These signatures include: • a lease with the fitness brand On Air, on the mid-size area of 2,000 m 2 located in the Carré Vélizy mixed-use complex in Vélizy-Villacoublay, which had been vacated in January 2022 by Office Dépôt. This new lease took effect on 29 April 2022; • two new leases with the Rougier & Plé brand, covering a total of 1,100 m 2 , for the takeover of the bookstore and the opening of a new boutique dedicated to creative leisure activities in the Passage de la Réunion in Mulhouse; • a new lease with the Takko Fashion brand for 700 m 2 at Aria Parc, a retail park located in Allonnes, focused on discount shopping and now 100% let; • three leases reinforcing the retailer mix, including in the Valentin shopping centre in Besançon. The physical and financial occupancy rates were 90% and 88% respectively as of 31 December 2022, stable compared to the situation as of 31 December 2021. Annualised net rents as of 1 January 2023 amounted to €15.1 million, up 62.4% year-on-year. This change is mainly due to the addition of the Flins-sur-Seine and Ollioules shopping centres. On a like-for-like basis, net annualised rents was up by 2.8% compared to 1 January 2022. Reverse stock split The consolidation of M.R.M.’s shares, the implementation of which was decided by the Board of directors at its meeting of 24 February 2022, began on 21 March 2022 and was completed on 20 April 2022, the day on which the new shares were listed. The reverse stock split was effected by exchanging twenty former shares with a par value of €1 for one new share with a par value of €20. The new shares are listed under ISIN code FR00140085W6. The former shares identified under ISIN code FR0000060196 r have been delisted. The ticker code is unchanged: M.R.M.
