This Amendment No. 2 amends the Original Schedule 13G, as amended by Amendment No. 1, as specifically set forth herein. Except as specifically set forth herein, this Amendment No. 2 does not modify any of the information previously reported on the Schedule 13G (including Amendment No. 1 thereto).
This Amendment No. 2 is being filed to solely to voluntarily disclose that on March 4, 2019, the Issuer entered into an implementation agreement (the “Implementation Agreement”) by and among the Issuer, Biogen Switzerland Holdings GmbH (“Biogen”) and Tungsten Bidco Limited (“Bidco”) whereby Bidco agreed to acquire the entire issued and to be issued share capital of the Issuer for $25.50 in cash per share (the “Scheme”). In connection with the closing of the transaction contemplated by the Implementation Agreement, the Issuer and Biogen entered into a Shareholder’s Irrevocable Undertaking (the “Undertaking”) with Syncona Portfolio Limited (“Syncona”) and New Enterprise Associates 15, L.P. to vote or procure votes in favor of the resolutions relating to the Scheme in respect of their entire beneficial holdings. The Undertaking will terminate if the Scheme lapses or is withdrawn in accordance with its terms and Bidder or Bidco publicly confirms that it does not intend to proceed with the acquisition or if the Scheme lapses or has not become effective by 11:59pm (London time) on September 4, 2019.
As a result of the Undertaking, the Reporting Persons may be deemed to be members of a “group” with the parties of the Undertaking. Syncona, together with New Enterprise Associates 15, L.P. is the beneficial owner of 19,866,454 Ordinary Shares, in aggregate, representing approximately 59.3% of the issued share capital of the Issuer as reported as of February 28, 2019 on the Issuer’s 8-K filed with the Securities and Exchange Commission (“SEC”) on March 4, 2019 (the “8-K”).
The foregoing description of the Undertaking is qualified in its entirety by reference to the Form of Shareholder’s Irrevocable Undertaking, which is attached hereto as Exhibit 99.2.
