FOR IMMEDIATE RELEASE

1^st February 2021
Marston's PLC

UPDATE ON POSSIBLE OFFER

Further to the announcement on Friday, 29th January 2021 that the Board of Marston's PLC ("Marston's" or the "Company") had received an unsolicited non-binding proposal from Platinum Equity Advisors, LLC ("Platinum") for the entire issued, and to be issued, share capital of Marston's (the "Proposal"), the Company provides the following update.

The Board of Marston's has considered the Proposal of 105 pence per Marston's share with its advisers, and unanimously rejected the Proposal on the basis that it very significantly undervalues Marston's. The Proposal followed two earlier proposals at 88 pence and 95 pence per share in December 2020, both of which were received prior to the Brains transaction, and were unanimously rejected by the Board.

The Proposal represents a 19% discount to the Company's share price at the start of 2020, pre-COVID 19; and since that time the Company has completed the transformative joint venture with Carlsberg to create the Carlsberg Marston's Brewing Company, which realised significant value on completion and is anticipated to continue to do so as the benefits of the joint venture are realised. In December 2020 the Company also announced an agreement to operate 156 high quality pubs within the SA Brain estate in South and West Wales, in a transaction which is expected to be accretive to earnings in the first full year of trading.

In accordance with Rule 2.6(a) of the Code, Platinum, is required, by no later than 5.00 p.m. (London time) on Friday, 26^th February 2021, being 28 days after Friday's announcement, to either announce a firm intention to make an offer for the Company 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 can be extended with the consent of the Takeover Panel (the "Panel") in accordance with Rule 2.6(c) of the Code.

This announcement has been made by Marston's without the prior agreement or approval of Platinum.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested 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 of the Code. A Dealing Disclosure by a person to whom Rule 8.3(b) of the Code 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 of the Code.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4 of the Code).
