Recommended all-share offer for Lonmin by Sibanye-Stillwater: Extension of Longstop Date to 30 June 2019

Johannesburg, 15 January 2019: On 14 December 2017, the Boards of Sibanye-Stillwater and Lonmin announced that they had reached agreement on the terms of a recommended all-share offer pursuant to which Sibanye-Stillwater, and/or a wholly-owned subsidiary of Sibanye-Stillwater, would acquire the entire issued and to be issued ordinary share capital of Lonmin (the “Offer”). The terms of the Offer are expressed to be conditional upon the Scheme becoming unconditional and effective by no later than the Longstop Date, being 28 February 2019 or such later date as Sibanye-Stillwater and Lonmin may, with the consent of the Panel, agree (and, if required, the Court may allow).

On 19 December 2018, Sibanye-Stillwater and Lonmin announced that the Association of Mineworkers and Construction Union had filed an appeal with the Competition Appeal Court of South Africa (the “CAC”) against the South African Competition Tribunal’s decision of 21 November 2018 to approve the Offer subject to certain specific conditions. In light of the appeal before the CAC, Sibanye-Stillwater and Lonmin have agreed, with the consent of the Panel, to extend the Longstop Date for the Scheme to become unconditional and effective from 28 February 2019 to 30 June 2019. Sibanye-Stillwater and Lonmin remain fully committed to the Offer.

Defined terms used but not defined in this announcement have the meanings set out in the firm offer announcement dated 14 December 2017.

Ends.

Disclosure requirements of the Takeover Code

Under Rule 8.3(a) of the Takeover Code (“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). 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 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 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 Takeover Panel’s website at http://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. If you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure, you should contact the Takeover Panel’s Market Surveillance Unit on +44 (0)20 7638 0129.]
