Discussions with Potential Offerors and Update Regarding Buyback Programme

On 14 January 2026, Senior plc (the "Company" or "Senior") received a preliminary, non-binding all-cash proposal from a potential offeror, which was unanimously rejected by the Board on the basis that it fundamentally undervalued Senior and its future prospects.  Two subsequent, higher proposals were received from the same party in February 2026, the second of which was unequivocally rejected by the Board.

Following the approaches described above, the Board appointed Lazard and Jefferies to initiate discussions with a limited number of third parties regarding a possible offer for the entire issued and to be issued share capital of Senior, to determine the value that could potentially be achieved.  Following a period of discussions with these other parties, the Company confirms it has received two further, superior all-cash proposals from other potential offerors.  Discussions with potential offerors remain ongoing.

In view of the Company's ongoing discussions with the potential offerors, and mindful of the Company's regulatory obligations, the Board has postponed the start of the £40m buyback programme which had been due to commence following publication of the full year results.  The Board will keep this under review and make a further announcement as necessary.

The Panel Executive has granted a dispensation from the requirements of Rules 2.4(a) and 2.4(b) of the Code such that the Company is not required to identify in any announcement any potential offeror with which the Company is in talks, or from which an approach has been received, unless that potential offeror has been specifically identified in any rumour or speculation.

Senior is now in an "offer period" as defined in the Code and the attention of Senior shareholders is drawn to the dealing disclosure requirements of Rule 8 of the Code, which are summarised below.

There can be no certainty that an offer will be made for the Company nor as to the terms on which any offer might be made.

This announcement has been made without the consent of any of the potential offerors.

The person responsible for arranging the release of this announcement on behalf of Senior is Andrew Bodenham, Company Secretary.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested (directly or indirectly) in 1% or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the offer period and, if later, following the announcement in which any securities exchange offeror is first identified.

An Opening Position Disclosure must contain details of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s).  An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 pm (London time) on the 10th business day following the commencement of the offer period and, if appropriate, by no later than 3.30 pm (London time) on the 10th business day following the announcement in which any securities exchange offeror is first identified.  Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested (directly or indirectly) in 1% or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror.  A Dealing Disclosure must contain details of the dealing concerned and of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror, save to the extent that these details have previously been disclosed under Rule 8.  A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 pm (London time) on the business day following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures and Dealing Disclosures must also be made by any persons acting in concert with the offeree company (see Rules 8.2 and 8.4).
