Fundamentals of the Group

Business model

Adler Group S.A. is a residential real estate company which – through its subsidiaries – holds and manages 17,483 rental units, primarily based in Berlin. This rental portfolio is valued at EUR 3.5 billion as per 31 March 2026. Besides the rental portfolio, Adler Group owns a portfolio of development projects in some of the larger cities in Germany valued at EUR 0.5 billion. In agreement with the bondholders under the terms of the Restructuring Plan, these development projects are to be sold – some sales processes have already begun, others are to be initiated.

Hence, the Adler Group's business model focuses on asset and portfolio management, property and facility management, targeting at improving operating results by increasing rents and decreasing vacancies in its existing portfolio. The portfolio shall be further optimised depending on opportunities or necessities.

Our 318 employees (as per 31 March 2026) are based in Luxembourg and in several locations across Germany in order to bring Adler Group as close as possible to assets and tenants.

Objectives and strategy

Focus on active management of the portfolio to grow earnings and improve EBITDA margins.

Adler Group focuses on increasing rents through active asset management and targeted investments to modernise, refurbish and re-position properties, while constantly screening and anticipating developments in different sub-markets. In order to realise upside potential, Adler Group pursues regular rent increases up to the market levels within the regulatory and legal limits without CapEx investment. In addition, Adler Group continuously reviews rent potentials and pursues growth beyond the rent tables through targeted CapEx investments to modernise, refurbish and/or re-position properties. Vacancies are kept low through active marketing tailored to the respective micro-location.

As apartments are typically renovated to market standard after a tenant has moved out, Adler Group is in the position to rent vacant apartments to higher quality tenants and thus to continuously improve the tenant structure and average rent.

Fundamentals of the Group

Optimise the portfolio and recycle capital through selective investments and disposals.

By disposing of non-core assets, Adler Group aims to streamline the rental portfolio and to focus on Berlin where a critical mass of assets can be managed thereby improving profitability and portfolio KPIs. Active capital recycling enables Adler Group to reduce leverage and ultimately to improve its capital structure.

Committed to adding value through refurbishment and modernisation.

Investing selected CapEx in refurbishment and modernisation measures in the existing portfolio will elevate the quality of the rental portfolio, improve energy efficiency in line with sustainability targets to reduce greenhouse gas emissions and thus add value overall.

Corporate Governance

The Company's corporate governance practices are governed by Luxembourg Law (particularly the Luxembourg law of 10 August 1915 on commercial companies, as amended) and the Company's articles of association. As a Luxembourg company with its shares admitted to trading on the regulated market (Prime Standard) of the Frankfurt Stock Exchange, the Company is not subject to any specific mandatory corporate governance rules. The corporate governance practices applied by the Company are those applied under general Luxembourg law.

(
*) Annualised net rental income.

In addition to our financial performance indicators, we also use the following operational performance indicators:

The vacancy rate shows the ratio of $m^2$ of vacant units in our properties to total $m^2$. Vacancy rate is used as an indicator of the current letting performance. Operational vacancy excludes unavailable units, i.e., units under refurbishment and decommissioned units.

The in-place rent per $m^2$ provides an insight into the average rental income from the rented properties. It serves as an indicator of the current letting performance.

The like-for-like rental growth is the change rate of the net rents generated by the like-for-like residential portfolio over the last 12 months.

The total amounts spent on maintenance and CapEx in relation to the total lettable area of the portfolio are further operational figures to ensure an appropriate level of investment in the real estate portfolio. Maintenance expenses are spent to keep the property in its current condition and are typically charged to the consolidated income statement. These maintenance measures ensure the living quality of tenants and tenant satisfaction, which in turn decreases vacancies and increases reletting rents, giving place to higher and stable rental income. CapEx measures comprise targeted investments that increase the quality, safety and overall features of the assets in the portfolio, supporting the

ability to capture higher rents. Examples of these investments include refurbishments of facade or roof as well as refurbishments of apartments. CapEx are typically capitalised to the investment properties. The diverse CapEx projects support the value growth of the portfolio and the letting process, resulting in lower vacancies and higher rent potential. Additionally, Adler Group carries investments aimed at improving the energy efficiency and $\mathrm{CO}_{2}$ reduction.

All of the above-described operational performance indicators are key drivers for the development of rental income.

Adler Group's fully integrated active asset management is focused on rental growth and employs dedicated strategies to drive all relevant components. In units that require modernisation, Adler Group invests CapEx to improve quality to meet today's standards and regulations. Applying the relevant regulatory framework accurately and efficiently is key to successfully maximising rental growth for let units.

Financial Overview

Financial performance indicators

Adler Group has been exposed to a challenging situation that was partly self-inflicted and largely caused by external factors since financial year 2022. The situation itself manifested in liquidity constraints, lack of financing capacities and dried real estate markets that made portfolio sales almost impossible. In order to cope with this situation, management decided to focus on always preserving enough liquidity as well as on net rental income as the main key performance indicators. The other financial performance indicators outlined below were not suspended but were followed with a much lower focus than usual. Consequently, we waive the explicit description of the financial performance indicators listed below.

After the recapitalisation completed in September 2024, the Company decided to no longer report the EPRA NAV & NTA metrics as a result of the IFRS accounting treatment of the newly introduced perpetual notes, which would account these as equity. As such, in management's view, EPRA NAV & NTA no longer reflect the intrinsic value of Adler Group correctly.

Income from rental activities equals net rental income plus income from facility services and recharged utilities costs.

NOI (net operating income) equals total revenue from the property portfolio less all reasonably necessary operating expenses. Aside from rent, a property might also generate revenue from parking and service fees. NOI is used to track the real estate portfolio's capability of generating income.

Adj. EBITDA from rental activities is an indicator of a company's financial performance and is calculated by deducting the overhead costs from NOI. It is used as a proxy to assess the recurring earnings potential of the letting business.

Adj. EBITDA Total can be derived by adding the net profit from project development activities to Adj. EBITDA from rental activities.

In addition, we present the NOI margin from rental activities – calculated as NOI divided by net rental income, as well as Adj. EBITDA margin from rental activities – calculated as Adj. EBITDA from rental activities divided by net rental income. These metrics are useful to analyse the operational efficiency at real estate portfolio level as well as at Company level.

We believe that the alternative performance measures described in this section constitute the most important indicators for measuring the operating and financial performance of the Group's business.

We expect all of the above-described alternative performance measures to be useful for our investors when evaluating the Group's operating performance, the net value of the Group's property portfolio and the level of the Group's indebtedness.

Due to rounding, the figures reported in tables and cross-references may deviate from their exact values as calculated.

Profit situation

Compared to the prior year period, net rental income in 3M 2026 decreased due to the lack of rental income resulting from the disposals of the NRW-based portfolio, completed in Q1 2025. The decrease was partly compensated by rent increases realised on the remaining assets.

The adjusted EBITDA from rental activities amounted to EUR 21 million, a decrease compared to the prior year period reflecting primarily the smaller portfolio size. The adjusted EBITDA Total amounted to EUR 14 million as the development segment did not contribute material earnings in this quarter and was impacted by construction costs.

FFO 1 and FFO 2 were both negatively impacted by net interest expenses.

Financial Overview

Financial and asset position

Investment properties remain almost unchanged due to the lack of larger disposals and no portfolio revaluation done in the first quarter 2026. Other non-current assets include other financial assets of EUR 103 million (mainly comprising loans against non-controlling shareholders of subsidiaries), property and equipment of EUR 11 million, restricted bank deposits of EUR 10 million and investments in financial instruments of EUR 8 million. Inventories primarily include upfront sale projects and the land value of forward sale projects. Other current assets include other receivables (EUR 85 million), trade receivables (EUR 61 million) and restricted bank deposits (EUR 28 million). Non-current assets held-for-sale decreased significantly due to disposals.

Interest-bearing debts include bonds, bank debt and the refinanced facilities as part of the recapitalisation completed in September 2024. Other liabilities include provisions (EUR 58 million), other current payables (EUR 121 million) including income tax payables of EUR 53 million and trade payables (EUR 45 million). Non-controlling interests decreased primarily as a result of the participation of non-controlling-interest-holders in the loss of certain subsidiaries.

As at 31 March 2026, the total interest-bearing nominal debt amounted to around EUR 3,639 million. The average interest rate on all outstanding debt was 7.1%, with a weighted average maturity of 3.2 years.

Forecast Report

Forecast for 2026

Following certain disposals made from the yielding asset-portfolio, Adler Group expects to generate net rental income for 2026 in the range of EUR 124-129 million.

In accordance with the Restructuring Plan, the Group continues to focus on liquidity management and deleveraging through planned asset and portfolio disposals.

Following the sanctioning of the Restructuring Plan in April 2023, the Company refrained from announcing an FFO 1 guidance for the year 2023 and thereafter due to the current situation of the Group which is primarily focused on steering its liquidity situation and de-leveraging through asset and portfolio disposals.
