This Amendment No. 1 (this “Amendment No. 1”) amends and supplements the Schedule 13D, originally filed on October 2, 2024 (the “Original Schedule 13D” and, together with this Amendment No. 1, the “Schedule 13D”). Except as set forth herein, the Original Schedule 13D remains in full force and effect.  Each capitalized term used but not defined herein has the meaning ascribed to such term in the Original Schedule 13D.

Item 4. Purpose of Transaction

Item 4 to the Schedule 13D is hereby amended to incorporate the following at the end thereof:

On November 6, 2024, OC Management sent a letter to the board of directors of the Issuer (the “Board”) expressing concern with the Issuer’s underperformance over 1, 2 and 3-year periods, and the over 50% drop in the Issuer’s stock price over the past year. OC Management highlighted notable strategic and communications problems at the Issuer, including failures to address competition to the Issuer’s core product Sublocade and guidance reductions, which have exacerbated investor concerns around the Issuer’s strategy and the Board’s willingness and ability to hold management accountable. OC Management urged the Board to address these issues immediately and work with OC Management on refreshing the Board with directors who are committed to taking all steps necessary to improve shareholder value and hold management accountable as they seek to address the Issuer’s performance. OC Management expressed its interest in working constructively with the Board, but noted that it is evident that shareholders are extremely concerned about the Issuer’s performance and direction and would support action to effectuate change if necessary. A copy of the letter is attached hereto as Exhibit 1 and incorporated herein by reference.

Item 5. Interest in Securities of the Issuer

Item 5 (a) and (b) of the Original Schedule 13D are hereby amended and restated as follows:

(a), (b)

The information set forth in rows (7) through (11) of the cover pages of this Schedule 13D is incorporated by reference into this Item 5.

The Reporting Persons hold an aggregate of 9,521,980 shares of Common Stock, representing 7.5% of the Common Stock outstanding as of the date hereof. All such ownership percentages of the securities reported herein are calculated assuming 127,219,020 Ordinary Shares outstanding as reported by the Issuer in its Form 6-K filed with the SEC on November 1, 2024.

In this regard, OVO Fund is the direct holder of 5,545,556 Ordinary Shares. VOF Fund is the direct holder of 2,351,370 Ordinary Shares. OPI Fund is the direct holder of 268,780 Ordinary Shares. OC Management is the investment manager to Boston Patriot Arlington St LLC, an SMA account which directly holds 1,356,274 Ordinary Shares. Oaktree GP I is the indirect general partner of OVO Fund, VOF, and OPI Fund, and as such may be deemed to beneficially own an aggregate of 8,165,706 Ordinary Shares. OC Holdings is the indirect general partner of OVO Fund, VOF, OPI Fund, and Oaktree GP I, and as such may be deemed to beneficially own an aggregate of 9,521,980 Ordinary Shares. OC Group Holdings is the indirect owner of the Class B Units of OC Holdings, and as such may be deemed to beneficially own an aggregate of 9,521,980 Ordinary Shares. Such amounts include an aggregate of 146,560 Ordinary Shares, representing 0.1% of the then-outstanding Common Shares, which were acquired on the London Stock Exchange prior to filing of the Original Schedule 13D but were inadvertently omitted from such filing. Brookfield is the indirect owner of the Class A1 Units OC Holdings, and as such may be deemed to beneficially own an aggregate of 9,521,980 Ordinary Shares. Each of the Reporting Persons disclaims beneficial ownership of the reported securities and the filing of this Statement shall not be construed as an admission of such beneficial ownership for the purposes of Section 13(d) or 13(g) of the Exchange Act.

Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by any of the Reporting Persons that it is the beneficial owner of any of the Common Stock referred to herein for the purposes of Section 13(d) of the Act, or for any other purpose.

Exhibit 24.1 Joint Filing Agreement, dated as of October 3, 2024, by and among the Reporting Persons, incorporated by reference to Exhibit 24.1 to the Schedule 13D.
