I. REVENUE AND BUSINESS REVIEW at 31 March 2026

Consolidated revenue and EU taxonomy alignment⁷

In the first quarter of 2026, Altarea's consolidated revenue⁸ amounted to €381.4 million, a decrease of -12.4% compared to the first quarter of 2025, due to a decline in Residential revenue (completion of older generation projects). New generation projects represented 70% of total Residential revenue, compared to 50% for the full year 2025.

As of March 31, 2026, the revenue alignment rate with the European taxonomy stood at 74.1% (vs. 73.9% for the full year 2025). This performance is linked to the weight of the new Residential operations, which are fully aligned.

Residential: growth in new orders to Individuals, Block sales of managed residences

Sales to Individuals are up in both volume (+15%) and value (+5%). This quarter, Block sales primarily involved managed residences, at lower unit prices⁹. For the full year 2026, the Group expects the average unit price for Block sales to be in line with previous years.

The Group launched 15 new programs for 596 units (+16%) and acquired 11 plots of land (compared to 2 in  Q1 2025).

At the end of March 2026, the retail supply remained stable at 2,756 units (-3%). This level allows the Group to adequately meet demand while also fulfilling its margin targets and prudential criteria.

Retail: solid operational performance¹⁰

Proactive asset management has resulted in positive indicators in a context where households remain cautious with their spending:

• tenants’ sales increased by +1.3%, driven by a +5.3% rise in footfall ;
• rental demand is dynamic with €10.2 million in lease signed since the beginning of the year (vs. €8.0 million in Q1 2025);
• occupancy rate at an optimal level of 97.1% (stable vs. 31/12/2025);
• and IFRS rental income as of 31 March 2026, increased by +1.9% to €61.3 million, including +1.2% on a like-for-like basis (+0.7% of indexation).

Business Property: solid progress on ongoing Offices & Logistics projects

Ongoing development projects are progressing as scheduled, both in the Paris area and in the regions.

Photovoltaics and Data Centers: finalization of two previously announced partnerships

In Photovoltaic infrastructure, Altarea has finalized a 25/75 partnership agreement¹¹ with several entities within the Crédit Agricole group, covering 124.6 MWp of solar infrastructure. The preliminary agreement for this partnership was announced during the publication of the 2025 annual results.

In the hyperscale data center segment, a partnership was signed at the end of February 2026 with Vantage Data Centers¹² for the design, marketing, and construction of a campus near Bordeaux on land owned by Altarea and with a 400 MW electrical grid connection authorization (Citadel project). The launch of this project is contingent upon the signing of agreements with the end user.

Financial position

At the end of March 2026, the Group's liquidity position¹³ was solid at €1,894 million (compared to €1,823 million at the end of March 2025).

In October, S&P Global Ratings confirmed the strength of Altarea's credit profile with a long-term rating of BBB- (Investment Grade) and a stable outlook.

II. 2026 OUTLOOK

In 2026, FFO¹⁴ is expected to increase significantly. Results should benefit from the continued recovery in Residential, a solid performance in Retail, one or more transactions in Business Property, and the overall breakeven of New businesses, subject to the political, geopolitical, and macroeconomic environment. Altarea did not record any direct impact from the conflict in the Middle East on its business in the first quarter, but the Group remains attentive to developments and their impact on the global macroeconomic environment.

In 2026, Altarea will continue to rely on its solid balance sheet structure and maintain strong liquidity, along with a financial policy consistent with an investment-grade rating.
