PHP advances Assura takeover with new share admissions as £1.8bn healthcare REIT merger moves forward

Why has Primary Health Properties’ Assura deal moved from unconditional status to ongoing implementation with new share admissions?

Primary Health Properties PLC (LSE: PHP; JSE: PHP) confirmed further progress in its recommended takeover of Assura PLC (LSE: AGR; JSE: AGR). The £1.8 billion offer was declared unconditional in all respects on 12 August 2025 after securing shareholder approval and regulatory clearance. With the legal certainty in place, PHP has since been issuing new shares to Assura investors who accepted the offer.

On 12 September 2025, PHP admitted 44,845,540 new shares to the Financial Conduct Authority’s Official List and to trading on both the London Stock Exchange Main Market and the Johannesburg Stock Exchange. Following this tranche, PHP now has 2,570,139,680 ordinary shares of 12.5 pence each in issue, with none held in treasury. This follows an earlier admission of 29.6 million shares on 4 September 2025, showing the phased nature of the settlement process as acceptances are processed.

This implementation update makes clear that while the headline unconditional milestone happened in August, September is about the practical mechanics: crediting new shares, adjusting capital, and preparing for Assura’s eventual delisting and re-registration as a private company once squeeze-out thresholds are met.

How does the takeover structure under Part 28 of the Companies Act shape the mechanics of the PHP–Assura deal?

The acquisition is being conducted by way of a takeover offer under Part 28 of the Companies Act 2006, bringing the full rigour of the UK Takeover Code. For each Assura share, investors are entitled to 0.3865 new PHP shares plus 12.5 pence in cash, alongside a special dividend of 0.84 pence declared by Assura. This mix of stock, cash, and dividend created a balanced offer, combining immediate liquidity with ongoing exposure to a larger healthcare REIT.

The structure means new shares are admitted in tranches to meet valid acceptances, with the offer unconditional as of August. Once PHP crosses the 90 per cent acceptance threshold, it can compulsorily acquire the remaining shares. At that point, Assura shares will be delisted from the London Stock Exchange and JSE, and the company will be re-registered as private, completing the transition.

The International Securities Identification Number (ISIN) for PHP’s ordinary shares is GB00BYRJ5J14, and its Legal Entity Identifier (LEI) is 213800Y5CJHXOATK7X11. These identifiers ensure investors and institutions can track regulatory disclosures and position changes, reflecting the transparency requirements that accompany UK public market takeovers.

Why did Assura’s board support PHP’s revised offer over private equity cash bids?

The backdrop to this merger was more dramatic than most REIT combinations. In early 2025, Assura attracted interest from private equity firms KKR and Stonepeak, which were preparing all-cash proposals. Such bids appealed to some shareholders for their simplicity and certainty, especially given the volatile interest rate environment weighing on property valuations.

However, Assura’s board ultimately recommended PHP’s revised shares-and-cash offer. The improved terms allowed investors to receive some cash upfront, retain public market exposure through PHP shares, and benefit from a special dividend. Institutional investors were particularly swayed by the argument that remaining in the listed REIT universe preserved liquidity and future upside. Private equity ownership, by contrast, would have removed that exposure and potentially loaded the business with higher leverage.

The decision to back PHP was therefore framed as maximising long-term shareholder value rather than chasing the highest short-term cash price. Analysts noted that by supporting PHP, Assura ensured continuity of dividend income and positioned shareholders to benefit from the enhanced scale of a combined healthcare property landlord.

How does this merger reshape the UK healthcare real estate investment trust sector?

The merger consolidates two of the largest specialist healthcare property REITs in the UK. Assura and PHP both built their reputations as landlords for GP surgeries, community health centres, and integrated medical facilities, typically leased on long-term, inflation-linked contracts to the NHS or equivalent public-sector tenants.

Assura’s portfolio stood at over £2.7 billion, while PHP’s assets exceeded £3.5 billion before the deal. The merger therefore creates a combined entity controlling more than £6 billion of healthcare real estate, providing unparalleled scale in this defensive asset class. In an environment where larger size translates into better access to capital, stronger negotiating leverage, and enhanced liquidity, the merger positions PHP as the clear sector leader.

This consolidation also reflects a broader global trend in REIT markets: fewer, larger vehicles dominating specialist niches. Investors have shown growing preference for scale, especially in markets subject to interest rate shocks, as larger REITs can access more favourable financing terms and attract deeper institutional demand.

How are markets reacting to PHP’s enlarged share capital and what is the sentiment among investors?

The market’s reaction has been measured. PHP’s share price dipped slightly around the offer period as investors priced in the dilution from new share issuance. Assura’s shares, by contrast, traded close to the implied offer value once the unconditional milestone was confirmed, reflecting arbitrage by event-driven funds.

For income-oriented investors, the attraction remains the dividend yield. Both PHP and Assura historically delivered yields of around five per cent, backed by long-term government-linked leases. Analysts suggest the enlarged REIT may be able to maintain, or potentially grow, distributions thanks to the broader portfolio. However, higher debt servicing costs remain a headwind, and management discipline in refinancing will be critical.

Institutional flows point to a rotation. Long-only funds that previously held Assura have accepted the offer and reinvested into PHP shares, ensuring continued exposure to healthcare property. Hedge funds that entered during the bid speculation phase have already booked profits. Retail investors now weigh whether the larger PHP offers stability and dividend resilience in a higher-for-longer interest rate environment.

Market consensus sits at a cautious “hold” for PHP’s existing investors, reflecting integration risks, and a pragmatic “buy” for former Assura shareholders who now hold stock in a larger, more liquid entity.

What risks and opportunities should shareholders monitor after the PHP–Assura integration?

The opportunities are clear. By merging, PHP creates a REIT with unmatched market share in UK primary healthcare property. This gives it greater bargaining power when negotiating with contractors and healthcare tenants, and makes it a natural allocation for pension funds and insurers seeking defensive real estate exposure.

Yet risks remain. Leverage and refinancing stand out, as both companies carried significant debt portfolios. Rising interest rates mean refinancing costs could erode net asset values and squeeze dividend cover. Property revaluations also matter, as any softening in valuations would hit reported NAVs. Integration complexity, from overlapping functions to harmonising reporting standards, is another potential challenge. Finally, dividend policy will be closely scrutinised, as maintaining or growing payouts is essential to the REIT investment thesis.

If PHP manages these challenges while delivering operational synergies, the merger could unlock further institutional demand and cement its position as the default healthcare REIT in the UK.

What does the future hold for healthcare REIT consolidation and investor interest in this asset class?

The PHP–Assura merger could be a catalyst for further consolidation in the UK REIT sector. With healthcare real estate viewed as a defensive, income-generating asset class, scale will matter more than ever. Smaller niche players may find themselves takeover targets, while private equity, although unsuccessful here, remains active with significant capital to deploy.

The enlarged PHP may also be in a stronger position to engage in ESG-linked property developments, particularly carbon-efficient healthcare hubs that align with NHS sustainability targets. As institutional investors increasingly demand green credentials, such projects could bolster demand for PHP’s stock.

For shareholders, the message is clear: the UK healthcare REIT landscape is narrowing into fewer, larger players with greater liquidity and visibility. The PHP–Assura deal underscores that trajectory.

How should the unconditional PHP–Assura merger update influence buy, sell, and hold decisions?

While the unconditional milestone was reached in August, September’s admissions of new shares confirm that the deal is being implemented on the ground. For Assura shareholders, the result delivers a mix of cash, a special dividend, and ongoing equity exposure through PHP stock. For PHP shareholders, the near-term challenge is integration and debt discipline, but the long-term prize is scale and stability in a sector with steady demand.

Investor sentiment is cautious but constructive. Existing PHP investors may hold their positions while monitoring dividend cover and financing strategy. Former Assura shareholders who accepted the offer gain a liquid stake in the UK’s leading healthcare REIT, with potential upside if management delivers.

This merger reshapes the market, consolidates leadership, and signals a new chapter for healthcare REIT investing in the UK. For long-term investors, the message is one of defensive yield with an added layer of scale — but execution will determine whether the enlarged PHP proves to be a market-beating allocation.
