CMA raises competition concerns over Welltower's UK senior care home acquisitions in a phase one merger review with potential remedies implications
The Competition and Markets Authority (CMA) has indicated that a series of acquisitions by Welltower — a US-listed real estate investment trust (REIT — a vehicle that owns and operates income-producing real estate) — in the UK senior care home sector may harm competition, according to Law360. The CMA's concern follows what appears to be a phase one merger investigation under the Enterprise Act 2002, the UK's principal merger control statute, into one or more of Welltower's deals to acquire senior living and care home assets in the UK. Welltower has been an active acquirer of UK healthcare real estate, and the CMA's competition concern suggests the regulator believes the cumulative effect of multiple acquisitions may be substantial enough to warrant a deeper investigation. Under the Enterprise Act, the CMA can refer a transaction for a full phase two investigation if it believes a merger has resulted or may result in a substantial lessening of competition (SLC). At phase one, the CMA may also accept undertakings in lieu of a reference — effectively negotiated remedies that allow a deal to proceed subject to conditions such as asset disposals. The care home sector is a sensitive area for UK competition authorities: consolidation among care home operators raises public interest concerns around the quality and accessibility of care as well as pricing, and the CMA has historically been prepared to require structural remedies in this sector.
Why this matters
The CMA's intervention in Welltower's care home acquisitions illustrates the regulator's increasingly active approach to real estate and healthcare sector consolidation, where multiple sequential acquisitions by a single buyer can cumulatively raise competition concerns even where individual deals fall below typical merger notification thresholds. For M&A lawyers advising healthcare and social care sector clients, this is a reminder that the CMA can investigate transactions on its own initiative within four months of completion, making the risk of post-completion CMA scrutiny a live deal consideration even for deals not voluntarily notified. The public interest dimension of care home consolidation — given the sector's social function and its elderly, often vulnerable, end users — makes the CMA particularly attentive to local market concentration.
On the Ground
A trainee on a CMA merger review matter would assist with preparing the disclosure verification exercise for any submissions to the regulator, help maintain a chronology of the relevant acquisitions and their completion dates, and support the drafting of responses to CMA information requests during the investigation period.
Interview prep
Soundbite
Serial acquisitions in care homes can trigger CMA scrutiny even without formal notification — post-completion reviews are a live deal risk.
Question you might get
“What are 'undertakings in lieu' of a CMA phase two reference, and when might a buyer prefer to offer them rather than face a full phase two investigation?”
Full answer
The CMA has flagged competition concerns about Welltower's UK senior care home acquisitions, potentially opening a phase one review under the Enterprise Act 2002. This matters because it demonstrates that the CMA will investigate serial acquirers in sensitive sectors — particularly healthcare — even where individual deals are not formally notified. The wider pattern is the CMA's growing willingness to use its call-in powers to scrutinise transactions that generate public interest concerns around service quality and market concentration. Advisers on healthcare real estate M&A transactions now need to build a systematic CMA risk assessment into deal timelines from the outset, accounting for the possibility of post-completion scrutiny and the need for phase one remedies.
