The Belgian Healthcare REIT Buying Europe One German Nursing Home at a Time

How Aedifica absorbed Cofinimmo, broke ground in Stadtlohn, and built Europe's largest healthcare real estate platform in a single year.

The Belgian Competition Authority cleared the path in January 2026. S&P upgraded the credit rating in March. Construction started in North Rhine-Westphalia the same month. By the time Aedifica completed its acquisition of just under 80% of Cofinimmo shares on March 10, 2026, the Brussels-listed REIT had spent the preceding twelve weeks executing three simultaneous moves that together added more than EUR 6 billion in assets to a portfolio already worth EUR 6 billion. The thread running through all of it is Germany, and behind Germany, arithmetic: an aging population, a structural shortage of licensed care beds, and a class of purpose-built real estate that operators cannot afford to leave.

From Brussels to Frankfurt: How Aedifica Got Here

Aedifica was founded in Brussels in 2006 and spent its first decade quietly assembling care home portfolios across Belgium. The company listed on Euronext Brussels that year and expanded its reach to Germany by 2013, recognising early that the country's demographic trajectory made it a structural growth market. By 2017, Aedifica had signed its first major framework agreement with the Specht Group, a developer and operator with more than 35 years of experience in German healthcare real estate. That relationship grew to encompass 23 Aedifica properties operated by Specht, and became the template for how the Belgian REIT built its German footprint: long-term partnerships with established operators, long lease structures with built-in maintenance guarantees, and purpose-built stock aligned to rising care standards.

CEO Stefaan Gielens, who has led the company since its founding and holds a law degree from KU Leuven, has framed Germany not as one market among many but as the core of the European healthcare real estate thesis. In the company's 2025 annual report, Gielens was explicit: with an aging population wave looming ever larger in Europe and market sentiment shifting as healthcare operators could once again think about growth, it was the right moment to create the leading healthcare real estate platform on the continent. By early 2026, he had done it.

The Cofinimmo Deal: Scale in One Move

The acquisition of Cofinimmo, announced in June 2025 and completed on March 10, 2026, was the largest healthcare REIT transaction in European history. Structured as an all-share voluntary exchange offer, Aedifica acquired a 79.57% stake in Cofinimmo by issuing 1.185 new Aedifica shares for each tendered Cofinimmo share. The Belgian Competition Authority approved the deal on January 21, 2026, conditional on Aedifica committing to divest approximately EUR 300 million of Belgian healthcare assets over several years. Regulators in Germany, the Netherlands, and France had already cleared the transaction.

The combined portfolio as of Q1 2026 stands at EUR 12.4 billion across 923 properties in ten European countries. Germany is the second-largest country allocation at 17% of combined gross asset value. The Cofinimmo portfolio alone brought 58 German nursing home properties into the combined entity, with a proportional value of approximately EUR 750 million according to JLL's Q1 2026 Germany Investment Market Overview. That figure made the transaction the largest German healthcare real estate deal of the quarter, surpassing even TPG Real Estate's EUR 400 million acquisition of the Northwest Healthcare Properties REIT German-Dutch portfolio. The healthcare sector recorded a transaction volume of approximately EUR 937 million in Q1 2026, the strongest quarter since Q4 2021.

The deal delivered immediate financial consequences. S&P Global raised Aedifica's long-term issuer credit rating from BBB to BBB+ with a stable outlook in March 2026, following the successful settlement of the exchange offer. Both boards had flagged a one-notch improvement as likely when they unanimously approved the combination in June 2025, noting it would lower borrowing costs in the bond market. The company expects approximately EUR 16 million in annual run-rate operating synergies by 2027, generated from streamlined third-party fees and consolidated governance structures.

Stadtlohn: The Ground-Up Bet

While the Cofinimmo integration dominates headlines, Aedifica simultaneously broke ground on a new care home in Stadtlohn, a town of roughly 20,000 people in the Borken district of North Rhine-Westphalia. The EUR 22 million investment, with contracts exchanged on January 19, 2026, will deliver a three-storey, 100-resident facility built to KfW 40 energy efficiency standards, equipped with air-source heat pumps, rooftop solar panels, and triple-glazed windows. Completion is expected in June 2028.

The Stadtlohn project will be operated by the Specht Group under a new 30-year double net lease with a 15-year triple net maintenance warranty. That structure is standard Aedifica practice in Germany: long, irrevocable leases that eliminate vacancy risk and pass a defined category of maintenance obligation back to the operator. The address sits at Burgstrasse 23 in the centre of Stadtlohn, on a plot Aedifica acquired in 2021 and held until construction financing and care demand aligned.

Andreas Jantsch, Aedifica's Country Manager for Germany, has articulated what the Stadtlohn project represents at a structural level: building the healthcare real estate of the future while providing a solution for the care and housing needs of Germany's ageing population. That framing is grounded in a concrete supply gap. Germany currently reports a shortfall of approximately 200,000 inpatient care units against existing supply, according to ImmoTISS Care. The care home market is expected to require between EUR 81 billion and EUR 125 billion in new investment by 2040 according to CBRE and immoTISS analysis, driven by both rising demand and the obsolescence of ageing stock.

The Demographic Engine

Germany's care sector dynamics are not subtle. The country is expected to have 5.7 million people in need of care by 2030, rising to 6.4 million by 2040, a 28% increase over 2021 levels that would require an additional 322,000 inpatient care places. The workforce math compounds the problem: approximately 40% of currently employed nursing staff are over 50 years old, and from 2030 onward there is projected to be one unfilled nursing position for every active nurse. The baby boom generation reaches retirement age while simultaneously removing workers from the sector and adding residents to it.

This is the paradox that benefits real estate investors. The structural undersupply of purpose-built facilities makes newly constructed, energy-efficient stock particularly valuable. Operators require modern buildings to attract and retain the limited qualified staff available. Regulators in multiple German states have upgraded building standards for licensed care facilities, making older stock increasingly expensive to maintain or renew. Aedifica's KfW 40 buildings sit at the upper end of what operators need to compete for both residents and staff.

The numbers in the Q1 2026 report reflect this positioning. Aedifica's weighted average unexpired lease term stands at 15 years, with an occupancy rate of 99.2% across the portfolio. That occupancy figure, in a market where closures from cost pressure and staffing constraints are accelerating, reflects the quality skew of Aedifica's assets. The company does not own the facilities where operators struggle to fill beds. It owns the facilities operators cannot afford to vacate.

Three Moves, One Direction

The legal merger of Aedifica and Cofinimmo is scheduled to take effect on July 1, 2026, following extraordinary general meetings convened for mid-June. The full run-rate impact of synergies is expected during 2027. In the meantime, Aedifica continues its development pipeline alongside the integration, with the EUR 300 million Belgian divestment program running in parallel with new construction starts and ongoing portfolio negotiations.

Jan-Bastian Knod, Head of Healthcare Advisory at Cushman and Wakefield Germany, noted in April 2026 that international investors are clearly focusing on German healthcare property and that the high proportion of foreign capital, combined with large-scale portfolio transactions, demonstrates growing confidence in established operator structures and sustainable revenue models. That confidence now flows through one company more than any other.

With a EUR 12.4 billion portfolio, a BBB+ credit rating, a 15-year average lease duration, and a ground-up construction program active in the same quarter as a multi-billion-euro M&A integration, Aedifica has built something rare in European commercial real estate: a platform whose growth case rests not on speculation, but on the arithmetic of a continent that is getting older faster than it is building the places to care for itself.
