Court Sanction of Scheme

On 17 December 2020, it was announced that the board of Tosca IOM Limited (the "Offeror") and the independent directors of TalkTalk Telecom Group PLC ("TalkTalk" or the "Company") had reached agreement on the terms of a recommended acquisition by the Offeror of the entire issued and to be issued share capital of TalkTalk.  The Acquisition is to be implemented by way of a Court-approved scheme of arrangement (the "Scheme").

The scheme document in relation to the Scheme (the "Scheme Document"), together with the associated Forms of Proxy and Form of Election, were published and posted to TalkTalk Shareholders (other than to TalkTalk Shareholders in certain Restricted Jurisdictions) and, for information only, to persons with information rights and participants in the TalkTalk Share Plans on 5 February 2021.

The Independent TalkTalk Directors are pleased to announce that, at the Court Hearing held earlier today, the High Court of Justice has made an order sanctioning the Scheme by which the Offeror's acquisition of TalkTalk is being implemented.

In addition, valid elections in respect of the Alternative Offer have been received by TalkTalk from TalkTalk Shareholders in respect of an aggregate of 645,710,628 TalkTalk Shares and, as such, the total Cash Consideration payable by the Offeror pursuant to the terms of the Scheme following it becoming Effective will be £485,542,270.74.

The last day of dealings in, and for registration of transfers of, and disablement in CREST of, TalkTalk Shares will be 11 March 2021.  The Scheme Record Time will be 6.00 p.m. on 11 March 2021.  No transfers of TalkTalk Shares will be registered after this time

Subject to the Court Order being duly delivered to the Registrar of Companies, it is anticipated that the Scheme will become Effective on 12 March 2021.  Accordingly, it is intended that dealings in TalkTalk Shares will be suspended at 7.30 a.m. on 12 March 2021 and that that the listing of the TalkTalk Shares on the Official List and the admission to trading of TalkTalk Shares on the main market for listed securities of the London Stock Exchange will, respectively, be cancelled with effect from 8.00 a.m. on 15 March 2021.

Notice to US investors

The Consideration Shares are expected to be issued in the United States in reliance upon the exemption from the registration requirements of the US Securities Act provided by section 3(a)(10) thereof.

For the purposes of qualifying for the exemptions from the registration requirements of the US Securities Act afforded by Section 3(a)(10), TalkTalk will advise the Court through counsel that the Court's sanction of the Scheme will be relied upon by the Offeror as an approval of the Scheme following a hearing on the fairness of the terms and conditions of the Scheme to TalkTalk Shareholders at which hearing all such shareholders are entitled to appear in person or through counsel to support or oppose the sanctioning of the Scheme and with respect to which notification has been given to all TalkTalk Shareholders.

TalkTalk Shareholders who are, or will be, affiliates of the Offeror after the Effective Date will be subject to certain US transfer restrictions relating to the Consideration Shares received pursuant to the Scheme. Otherwise, the Consideration Shares generally should not be treated as "restricted securities" within the meaning of Rule 144(a)(3) under the US Securities Act and persons who receive securities under the Scheme (other than certain affiliates of the Offeror) may resell them without restriction under the US Securities Act.

The receipt of Consideration Shares or cash pursuant to the Acquisition by a US TalkTalk Shareholder will be a taxable transaction for US federal income tax purposes, and may also be a taxable transaction under applicable state and local tax laws, as well as foreign and other tax laws.  Each TalkTalk Shareholder is urged to consult their independent professional advisor immediately regarding the tax consequences of the Acquisition. US TalkTalk Shareholders should also read sub-paragraph 18.2 of Part II (Explanatory Statement) of the Scheme Document.

It may be difficult for US TalkTalk Shareholders to enforce their rights and claims arising out of the US federal securities laws, since the Offeror and TalkTalk are located in countries other than the United States, and some or all of their officers and directors may be residents of countries other than the United States. US TalkTalk Shareholders may not be able to sue a non-US company or its officers or directors in a non-US court for violations of the US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court's judgment.

None of the securities referred to in this announcement have been approved or disapproved by the SEC, any state securities commission in the United States or any other US regulatory authority, nor have such authorities passed upon or determined the adequacy or accuracy of the information contained in this document.  Any representation to the contrary is a criminal offence in the United States.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in one per cent. 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 p.m. (London time) on the 10th business day following the commencement of the offer period and, if appropriate, by no later than 3.30 p.m. (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 in one per cent. 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(s), 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 p.m. (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 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).

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Panel's website at www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the offer period commenced and when any offeror was first identified. You should contact the Panel's Market Surveillance Unit on +44 (0)20 7638 0129 if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.
