Ortho Clinical Diagnostics Holdings Plc (“Ortho”): Notice of UK Court Scheme Directions Hearing

Further to the joint announcement by Ortho and Quidel Corporation (“

Quidel

”) on December 23, 2021 of the signing of a definitive business combination agreement, Ortho announces that, as a preliminary procedural step in the process of implementing the combination, Ortho has scheduled a hearing of the High Court of Justice of England and Wales (the “

UK Court

”) to seek the UK Court’s consent and directions to convene a meeting of Ortho shareholders as part of the scheme of arrangement of Ortho proposed to be made pursuant to Part 26 of the Companies Act 2006 (the “

UK Scheme

”) for the purpose of implementing the business combination (the “

UK Scheme Directions Hearing

”).

Under the provisions of Part 26 of the Company Act 2006, a scheme of arrangement must be agreed by a majority in number (the "numerosity" majority), representing at least 75 per cent. in value (the "value" majority), of each class of scheme shareholders present and voting either in person or by proxy, together as a class at the relevant class meeting ordered to be summoned by the Court for the purposes of considering the scheme.

At the UK Scheme Directions Hearing, Ortho will seek the UK Court’s confirmation that, for the purposes of voting at the UK Court meeting of Ortho shareholders to be held in respect of the UK Scheme, Cede & Co and GTU Ops Inc. (each a “Depositary Nominee”) are treated as a single class of Ortho shareholders (the Depositary Nominees currently being Ortho’s only registered shareholders, who hold shares as nominee for Depositary Trust Company and Computershare Limited respectively). Ortho shall also seek the UK Court’s directions to confirm that on the application of the numerosity requirement, as each Depositary Nominee is required to cast votes on the UK Scheme to reflect the instructions of underlying beneficial holders of Ortho shares, each Depositary Nominee shall be treated as a registered shareholder voting in accordance with how a majority of the shares it is validly instructed by underlying beneficial shareholders to vote are cast.

The UK Scheme Directions Hearing is expected to take place on February 15, 2022. It is a matter for the UK Court as to whether the hearing is in person, virtual only using Microsoft Teams (or such other videoconferencing software as the UK Court decides) or hybrid. The time of the hearing will be set out on HM Courts & Tribunals Service’s website at www.justice.gov.uk/courts/court-lists. Ortho shareholders who wish to attend the UK Scheme Directions Hearing, or wish to instruct counsel to attend the UK Scheme Directions Hearing and to make representations to the UK Court on his or her behalf, should confirm their intention to attend by email to [e-mail] (with a copy to [e-mail]) specifying their name and email address, and if applicable, the name and email address of their counsel. Any requisite videoconferencing link will be provided to such parties directly by the UK Court.

You should note that this announcement has been prepared in accordance with the procedure and guidance laid down by the UK Court in Practice Statement (Companies: Schemes Of Arrangement Under Part 26 And Part 26A Of The Companies Act 2006) issued on 26 June 2020 but this announcement is not soliciting a vote in respect of any meeting of Ortho shareholders, which shall be held to seek the approval of Ortho shareholders to the UK Scheme and for which specific instructions on voting and proxy voting materials will be set forth in the definitive joint proxy statement/prospectus to be issued by Quidel and Ortho relating to the proposed business combination (the “Joint Proxy Statement”) to be mailed to Ortho shareholders of record in due course. Beneficial holders of Ortho shares will also receive instructions on how to provide voting instructions or obtain a legal proxy from their broker, bank, trust or other nominee,

Further details of the implementation process, including further detail of the expected timetable and the action to be taken by Ortho shareholders will be included in the Joint Proxy Statement which is expected to be published by Ortho and Quidel during the first quarter of 2022.
