Assura rejects KKR’s advances and backs Primary Health Properties’ £1.8bn takeover offer

In one of the UK’s most closely watched healthcare real estate contests in years, Assura plc has reaffirmed its support for a £1.79 billion cash-and-shares takeover by Primary Health Properties plc (PHP), despite sustained lobbying from a private equity consortium led by Kohlberg Kravis Roberts & Co. (KKR) and Stonepeak Partners. The decision sets the stage for a shareholder showdown later this month, with Britain’s Competition and Markets Authority (CMA) actively reviewing whether the merger warrants a full investigation.

Assura, a specialist in developing, investing in and managing medical centres for National Health Service (NHS) general practitioners, told investors that the PHP offer provides the most compelling combination of value, strategic fit and execution certainty. The board emphasised PHP’s proven track record in managing healthcare properties and its operational alignment with Assura’s portfolio, which comprises more than 600 sites across the UK.

Why did Assura reaffirm its support for Primary Health Properties instead of KKR’s all-cash bid?

The decision follows a months-long bidding battle in which the KKR-Stonepeak consortium had initially gained traction with an all-cash offer valued at roughly £1.7 billion, including dividends. The consortium argued that its bid avoided regulatory hurdles and provided immediate liquidity. However, Assura’s board shifted its stance in late June, citing the enhanced value of PHP’s mixed cash-and-share proposal, the strategic benefits of scale, and the potential for cost synergies.

Market volatility has since altered valuations. KKR contends that falling share prices across the healthcare property sector now make its all-cash proposal more attractive on a per-share basis than PHP’s, and has signalled that it could return with an improved offer should shareholders reject the current merger plan. Assura’s leadership, however, maintains that the PHP deal offers greater long-term security and positions the combined group to benefit from its status as a listed real estate investment trust (REIT) with predictable, inflation-linked rental income.

How are market conditions and regulatory oversight shaping the takeover battle?

The CMA has already issued an initial enforcement order and begun a preliminary review of the PHP-Assura deal, focusing on the potential impact on competition in the ownership and leasing of primary healthcare facilities. Any extended investigation could delay completion, creating a risk factor for both sides.

In the interim, both suitors are appealing directly to shareholders. Institutional investors are assessing not only the headline valuation but also the likely timetable for completion. Analysts note that in today’s higher interest rate environment, the cost of capital and refinancing strategies weigh heavily on valuations in the healthcare REIT segment. A combined PHP-Assura entity could unlock economies of scale in financing and asset management, potentially offsetting some of those pressures.

What role do property valuations and Assura’s recent results play in its defence of the merger?

Assura’s latest annual results, delivered earlier this summer, strengthened its case for remaining in the public market through a strategic combination. The company reported a marked rebound in portfolio valuations, which rose to approximately £3.1 billion, alongside a 16–17 percent increase in rental income to £167 million. Pre-tax profit surged to £166 million, reversing a prior-year loss, underscoring the resilience of long-term, government-backed leases in the healthcare property sector.

These performance metrics bolster the argument that a merger with PHP could deliver sustained growth, greater negotiating power with lenders, and operational efficiencies. For investors focused on steady, inflation-linked yields, the listed REIT structure remains an appealing alternative to a private equity-led buyout.

How are analysts and institutional investors positioning ahead of the shareholder vote?

While both sides have supporters, early indications suggest stronger institutional alignment with PHP’s offer. Large asset managers with existing stakes in healthcare real estate appear to favour the liquidity and potential upside of holding shares in an enlarged PHP-Assura entity. Analysts point to the potential for cost synergies in property maintenance, tenant management and back-office functions, as well as the strategic advantage of owning over 1,000 medical properties nationwide.

Conversely, backers of the KKR-Stonepeak proposal highlight the certainty of cash, the absence of equity market risk and the ability to redeploy capital elsewhere. Some hedge funds and event-driven investors are reportedly monitoring for signs that KKR might improve its terms if it gains sufficient shareholder traction.

What could the outcome mean for the UK’s healthcare real estate sector?

If PHP secures the necessary shareholder approvals and clears CMA scrutiny, the combined group would emerge as the UK’s largest landlord of GP surgeries and primary care facilities. That scale could deliver lower borrowing costs, enable more efficient portfolio rationalisation and accelerate investment in modern, sustainable healthcare infrastructure.

Should shareholders instead favour the KKR-Stonepeak bid, Assura would transition to private ownership. That scenario could prompt a more aggressive expansion strategy, potentially involving acquisitions beyond the UK, but it would also remove the company from the transparency and governance standards of the public market.

Either outcome will be closely watched by global investors, as the contest reflects a broader trend: rising international interest in inflation-protected, infrastructure-like assets in mature markets. With healthcare demand largely immune to economic cycles, primary care property is increasingly viewed as a defensive investment class.

What is the expected timeline for the decision and what are the key variables to watch?

The shareholder vote on the PHP–Assura merger is scheduled for the final week of August, setting a clear deadline for both sides to consolidate support. While the voting outcome will ultimately be determined by the proportion of institutional and retail shareholders aligning with each camp, the Competition and Markets Authority’s findings are widely expected to shape the final timetable. If the CMA signals the need for a deeper Phase 2 investigation into the deal’s impact on competition in the UK healthcare real estate market, integration could be delayed by several months — potentially testing investor patience and opening the door to fresh negotiations.

In the weeks leading up to the ballot, investors are expected to monitor not only the possibility of revised bids but also a broader set of macroeconomic and market indicators that directly influence valuations in the real estate investment trust sector. Chief among these are movements in UK gilt yields, which affect the discount rates used to value long-term, inflation-linked rental streams from medical centre leases. A sustained rise in yields could pressure REIT share prices and challenge the relative appeal of PHP’s share-based consideration, while stable or falling yields might bolster the attractiveness of retaining equity exposure to the enlarged entity.

Bank of England policy decisions are another focal point, particularly as the central bank weighs inflation dynamics against the need to support economic growth. A shift in base rates can have a significant knock-on effect on financing costs for property acquisitions, portfolio refinancing, and development projects. For a combined PHP–Assura platform with more than 1,000 healthcare properties, the cost of debt will directly influence distributable income and, by extension, dividend capacity — a key consideration for income-oriented investors.

Institutional sentiment at present remains divided but notably measured. Many long-only asset managers appear to be adopting a “wait-and-see” stance, reserving their final decision until there is greater clarity from regulators and a more definitive sense of whether either party will adjust their terms before the shareholder vote. Event-driven funds and arbitrage players are reportedly positioning for short-term volatility, betting on the potential for a last-minute improvement in the KKR–Stonepeak offer or a sweetened PHP proposal to lock in incremental support.

In practical terms, the coming weeks will be a critical period for deal-making diplomacy. Both suitors are expected to ramp up direct engagement with top shareholders, deploy additional investor presentations, and sharpen their messaging on execution certainty, regulatory risk, and value creation potential. For the wider UK healthcare real estate market, the outcome could set a precedent for how competition authorities approach future consolidations in a sector that is both essential to public health delivery and increasingly targeted by global capital seeking stable, inflation-protected returns.
