FOR IMMEDIATE RELEASE

21 August 2026

Spire Healthcare Group plc

("Spire Healthcare", the "Company")
Further extension of the PUSU Deadline

On 14 May 2026, the Company announced that it had received a revised non-binding proposal (the "Proposal") from funds advised by Toscafund Asset Management LLP ("Toscafund"), the Company's second largest shareholder, regarding a possible cash offer of 250 pence per Spire Healthcare share for the entire issued and to be issued ordinary share capital of Spire Healthcare (the "Cash Offer"). The Proposal includes an option for Spire Healthcare shareholders to elect for an unlisted rollover equity alternative in respect of some or all of their Spire Healthcare shares.

The Proposal is subject to the satisfaction or waiver of a number of customary pre-conditions, including completion of confirmatory due diligence and agreement of definitive transaction documentation.

As set out in the Company's announcement on 6 August 2026, in accordance with Rule 2.6(a) of the Code, Toscafund is currently required, by not later than 5.00 p.m. (London time) on 21 August 2026 (the "PUSU Deadline"), either to: (i) announce a firm intention to make an offer for the Company in accordance with Rule 2.7 of the Code; or (ii) announce that it does not intend to make an offer for the Company.

Toscafund has confirmed to the Board that its due diligence has concluded and that it continues to work towards the announcement of a 250 pence per Spire Healthcare share recommended offer. Given that due diligence has concluded and the ongoing progress being made on transaction documentation, Toscafund has requested that the Board grants a further extension to enable it to finalise its financing arrangements, which are near-final.

Accordingly, the Board has therefore requested, and the Takeover Panel has consented to, a further extension to the PUSU Deadline. Consequently, in accordance with Rule 2.6(a) of the Code, Toscafund is now required, by not later than 5.00 p.m. (London time) on 3 September 2026, either to announce a firm intention to make an offer in accordance with Rule 2.7 of the Code or announce that it does not intend to make an offer, in which case the announcement will be treated as a statement to which Rule 2.8 of the Code applies. This deadline may be further extended by the Company with the consent of the Takeover Panel, in accordance with Rule 2.6(c) of the Code.

This announcement is being made with the approval of Toscafund.

In accordance with Rule 2.5(a) of the Code, Toscafund reserves the right to make an offer for Spire Healthcare at a lower value or on less favourable terms than the Proposal and/or not to offer the unlisted rollover equity alternative: (i) with the agreement or recommendation of the Board; (ii) if a third party announces a firm intention to make an offer for Spire Healthcare which, at that date, is of a value less than the value of the Proposal; or (iii) following the announcement by Spire Healthcare of a Rule 9 waiver transaction pursuant to Appendix 1 of the Code or a reverse takeover (as defined in the Code). If Spire Healthcare declares, makes or pays any dividend or distribution or other return of value or payment to its shareholders, Toscafund reserves the right to make an equivalent reduction to the Proposal. Toscafund reserves the right to introduce other forms of consideration and/or vary the form or mix of consideration of any offer. Toscafund reserves the right to waive any pre-condition to the making of an offer.

There can be no certainty that any firm offer will be made even if the pre-conditions are satisfied or waived. A further announcement will be made in due course as appropriate.

The person responsible for arranging the release of this announcement on behalf of the Company is Mantraraj Budhdev, Group General Counsel and Company Secretary.

Forward looking statements

This announcement, oral statements made regarding potential strategic actions or initiatives, and other information published by Spire Healthcare may contain statements which are, or may be deemed to be, "forward-looking statements. Forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and projections of the management of Spire Healthcare about future events, and are therefore subject to risks and uncertainties which could cause actual results to differ materially from the future results expressed or implied by the forward-looking statements. The forward-looking statements contained in this announcement include statements relating to the expected effects of potential strategic actions or initiatives on Spire Healthcare, the expected timing and scope of potential strategic actions or initiatives and other statements other than historical facts. Often, but not always, forward-looking statements can be identified by the use of forward-looking words such as "plans", "expects" or "does not expect", "is expected", "is subject to", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates" or "does not anticipate", or "believes", or variations of such words and phrases or statements that certain actions, events or results "may", "could", "should", "would", "might" or "will" be taken, occur or be achieved. Although Spire Healthcare believe that the expectations reflected in such forward-looking statements are reasonable, Spire Healthcare can give no assurance that such expectations will prove to be correct. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future. There are a number of factors that could cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements. These factors include uncertainties involved in the integration of acquisitions and new developments, changes in legislation and/or the regulatory regime governing healthcare in the UK, poor performance by consultants who practice at our facilities, unexpected regulatory actions or suspensions, competition in general, the impact of global economic changes, risks arising out of health crises and pandemics, changes in tax rates, future business combinations or dispositions, and Spire Healthcare and its group undertakings' ability to obtain or maintain accreditation or approval for its facilities or service lines. Other unknown or unpredictable factors could cause actual results to differ materially from those in the forward-looking statements. Such forward-looking statements should therefore be construed in the light of such factors. Spire Healthcare, nor any of its respective associates or directors, officers or advisers, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this announcement will actually occur. You are cautioned not to place undue reliance on these forward-looking statements. Other than in accordance with their legal or regulatory obligations (including under the UK Listing Rules and the Disclosure Guidance and Transparency Rules of the FCA), Spire Healthcare is under no obligation, and Spire Healthcare expressly disclaims any intention or obligation, to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

No statement in this announcement is intended as a profit forecast or profit estimate.
