CUSIP No. G5920M100		Page 17 of 19 Pages

Item 4. Purpose of the Transaction

Item 4 of the Schedule 13D is amended to add the following:

As previously disclosed, (i) on April 24, 2024, Bidco announced the terms of its recommended cash offer to acquire the entire issued and to be issued share capital of Issuer for $0.55 per share (the “Cash Offer”); or, as an alternative to the Cash Offer, eligible shareholders of Issuer could elect to receive one unlisted, unregistered non-voting Class B unit of Topco (the “Unlisted Unit Alternative” and with the Cash Offer, collectively, the “Offer”); and (ii) in connection with the Offer, the Reporting Persons entered into Deeds of Irrevocable Undertakings in which they each agreed to accept or elect (i) the Cash Offer or alternatively (if Bidco or certain affiliates of Bidco elect to switch to a scheme of arrangement with respect to Issuer under the Irish Companies Act 2014) the scheme of arrangement under the Companies Act 2014 or (ii) other than the Runa Entities, the Unlisted Unit Alternative.

The Cash Offer expired at 5:00 p.m. (New York City time) on July 23, 2024 (the “Expiration Time”). The Reporting Persons tendered, or caused to be tendered, all of the Ordinary Shares owned by the Reporting Persons in the Offer, for the right to receive a cash payment of $0.55 per Ordinary Share or, other than the Runa Entities, the Unlisted Unit Alternative. As a result of the satisfaction of the conditions to the Offer, Bidco accepted all Ordinary Shares validly tendered (and not properly withdrawn) pursuant to the Offer.

The Ordinary Shares tendered, or caused to be tendered, by the Reporting Persons in the Offer constituted all of the Ordinary Shares beneficially owned by the Reporting Persons.

Accordingly, as of July 23, 2024, the Reporting Persons ceased to beneficially own any Ordinary Shares of the Issuer.
