FOR IMMEDIATE RELEASE

15 August 2022

M&C Saatchi plc

("M&C Saatchi" or the "Company")

Update for Shareholders on Regulatory Filings and Associated Timetable

As detailed in the M&C Saatchi Scheme Document dated 17 June 2022, the Next 15 Offer is conditional, amongst other things, upon certain competition and regulatory approvals being obtained, including UK CMA merger control approval, and approvals under the UK National Security and Investment Act 2021 ("NSIA"), the Australian foreign investment regulatory framework and from the US Committee on Foreign Investment in the United States ("CFIUS").

As noted in its announcement earlier today, Next Fifteen Communications Group plc ("Next 15") has now received the required regulatory approvals pursuant to the NSIA and the Australian foreign investment regulatory framework. In addition, in respect of Condition 3(c)(i) of the Next 15 Offer, the CMA has responded to the briefing paper submitted by Next 15 in respect of the Next 15 Offer and confirmed that it has no further questions in relation to the Next 15 Offer and, as at the date of this announcement, has not otherwise opened an inquiry, or indicated in writing that it is still investigating whether to open an inquiry.

Accordingly, the only regulatory approval remaining outstanding for Next 15 is the CFIUS approval in the United States which it is expected will be received during the early part of Q4 2022 as detailed in the M&C Saatchi Scheme Document and in previous Company announcements.

In the defence circular published by M&C Saatchi on 28 June 2022 in connection with the offer by AdvancedAdvT Limited ("ADV"), M&C Saatchi noted that ADV had failed to include any regulatory conditions in the timetable of the ADV Offer and flagged to M&C Saatchi Shareholders the risks associated with ADV's failure to make the appropriate foreign direct investment filings. Subsequently, ADV acknowledged this omission and made the appropriate filings in respect of both the Australian foreign investment regulatory framework and the NSIA.

As noted in its announcement earlier today, ADV has now received its mandatory regulatory clearances pursuant to the NSIA and the Australian foreign investment regulatory framework.

The Company's advisers have emphasised to ADV's advisers the importance of also seeking CFIUS approval with respect to the ADV Offer but were informed by ADV's advisers that ADV does not consider the pursuit of CFIUS approval from the American regulators to be warranted. The M&C Saatchi Directors believe that CFIUS will wish to understand the work performed by the M&C Saatchi Group in support of the US Government to which a material proportion of the M&C Saatchi Group's revenue is attributable. The M&C Saatchi Directors believe that closing the ADV Offer without formally notifying CFIUS of this transaction would be viewed unfavourably by CFIUS and may carry business risk for M&C Saatchi given the US Government's sensitivity to foreign ownership of government contractors and its broad discretion to terminate relevant contracts without cause. Furthermore, the M&C Saatchi Directors understand that, in the absence of a pre-closing notification to CFIUS concerning the ADV Offer, CFIUS would have authority to review the ADV Offer post-closing - a process that likely would last several months and carry with it an uncertain outcome.

Consequently, the M&C Saatchi Directors consider that it is in the best interests of M&C Saatchi Shareholders for ADV to remove any uncertainty with respect to the consequences of foregoing appropriate regulatory filings in the United States, as Next 15 has done, and urge both M&C Saatchi Shareholders and ADV Shareholders to suggest that ADV jointly submit a CFIUS filing with M&C Saatchi with respect to the ADV Offer.

M&C Saatchi notes that both the existence of the ADV Offer and M&C Saatchi's understanding that ADV intends to forego CFIUS review with respect to the ADV Offer will be noted in the disclosures made by M&C Saatchi to CFIUS with respect to the Next 15 Offer.

Should ADV change its position with respect to the advisability of a pre-closing CFIUS filing, M&C Saatchi will support ADV in the preparation of such filing to ensure the M&C Saatchi / ADV CFIUS review can commence expeditiously.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested 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).

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 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.

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 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).
