This Amendment No. 1 to Schedule 13G amends and restates in its entirety the Schedule 13G previously filed by BV IV L2, BCIV L1, BC IV, BCP IV, BCIL, Chandratillake, Misso, Andrew Whittaker and Nicolle (together with all prior and current amendments thereto, this “Schedule 13G”).

ITEM 2(A). NAME OF PERSONS FILING

This Amendment No. 1 to Schedule 13G is filed by BV IV L2, BCIV L1, BC IV, BCP IV, BCIL, Chandratillake, Misso, Mauger and Nicolle. Andrew Whittaker is no longer a director of BCIL and, therefore is not included as a Reporting Person on this Schedule 13G. The foregoing entities and individuals are collectively referred to as the “Reporting Persons.”

BC IV L1, the sole shareholder of BC IV L2, may be deemed to have sole power to vote and sole power to dispose of the shares of the Issuer owned directly by BC IV L2. BC IV, the sole shareholder of BC IV L2, may be deemed to have sole power to vote and sole power to dispose of the shares of the Issuer owned directly by BC IV L2. BCP IV, the sole general partner of BC IV, may be deemed to have sole power to vote and sole power to dispose of the shares of the Issuer owned directly by BC IV L2. Voting and dispositive power of BCP IV is delegated to BCIL and BCIL may be deemed to have sole power to vote and sole power to dispose of the shares of the Issuer owned directly by BC IV L2. Chandratillake, Misso, Mauger and Nicolle, the directors of BCIL, may be deemed to have shared power to vote and shared power to dispose of the shares of the Issuer directly owned by BC IV L2. Each of BCIV L1, BC IV, BCP IV, BCIL, Chandratillake, Misso, Mauger and Nicolle disclaims beneficial ownership of the shares of the Issuer owned directly by BC IV L2, except to the extent of their respective pecuniary interests therein.

Bernard Liautaud, a general partner of Balderton Capital and former member of the board of directors of the Issuer, has not and does not exercise any power to vote or dispose of the shares of the Issuer directly owned by BC IV L2 and, therefore, is not included as a “Reporting Person” on this Schedule 13G.

Pursuant to a Shareholder Agreement (the “Shareholders Agreement”) among the Issuer, certain of the Reporting Persons, and entities affiliated with Bpifrance Investissement, Galileo Partners, Idinvest Partners and Silver Lake (each, a “Major Shareholder”), certain affiliates of each Major Shareholder, other than Galileo Partners (collectively, the “Nominating Shareholders”), are entitled to nominate one member of the Issuer’s board of directors as long as certain continuing ownership thresholds are met. The Major Shareholders have agreed to vote for these nominees pursuant to the Shareholders Agreement.

By virtue of the Shareholders Agreement and the obligations and rights thereunder, the Reporting Persons, the Nominating Shareholders and/or certain of their affiliates may be deemed to constitute a “group” for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based in part on information provided by the Issuer, such a “group” would be deemed to beneficially own, as of December 31, 2017, an aggregate of approximately 9,843,646 Ordinary Shares, or approximately 33.2% of the Ordinary Shares calculated pursuant to Rule13d-3. The Reporting Persons expressly disclaim beneficial ownership over any ordinary shares that they may be deemed to beneficially own solely by reason of the Shareholders Agreement. Certain entities affiliated with the other Major Shareholders are separately making Schedule 13G filings reporting their beneficial ownership of Ordinary Shares.
