Proxy Statement Pursuant to Section 14(a) of
the Securities Exchange Act of 1934 (Amendment No. )

On April 26, 2024, LivaNova PLC (the “Company”) filed its definitive proxy statement and notice of Annual General Meeting (the “Proxy Statement”) with the Securities and Exchange Commission (“SEC”) in connection with the Company’s 2024 Annual General Meeting of Shareholders (“AGM”) to be held on June 11, 2024. This supplement (the “Supplement”) to the Proxy Statement is being filed to add Proposal No. 12, which is a non-binding, advisory vote on the frequency of holding an advisory vote on the compensation of the Company’s named executive officers, which is required by SEC rules to be included every six years. Specifically, the Company is asking its shareholders to vote, on a non-binding, advisory basis, with respect to the frequency of holding an advisory vote on executive compensation, as described herein. The recommendation of the Company’s Board of Directors (the “Board”) is that the Company continue to hold such an advisory vote on an annual basis and that the shareholders therefore vote for a frequency of “1 YEAR”.

Other than the changes described in this Supplement, which adds Proposal No. 12 and makes other conforming changes to the Proxy Statement, no other changes have been made to the Proxy Statement, and the Proxy Statement continues to be in full force and effect as originally prepared. Accordingly, we urge you to read the Supplement carefully and in its entirety together with the Proxy Statement. A form of the revised proxy card reflecting the addition of Proposal No. 12 has also been included in this filing.

On April 26, 2024, LivaNova PLC (the “Company”) filed its definitive proxy statement and notice of Annual General Meeting (the “Proxy Statement”) with the Securities and Exchange Commission (“SEC”) in connection with the Company’s 2024 Annual General Meeting of Shareholders (“AGM”) to be held on June 11, 2024. Subsequent to that date, the Company determined that it had inadvertently omitted a required proposal to shareholders related to the frequency of future advisory votes regarding the compensation of the Company’s named executive officers. This Supplement has been prepared to provide our shareholders with information regarding a new Proposal No. 12, a non-binding, advisory vote regarding the frequency with which the Company’s shareholders shall have the advisory, non-binding say-on-pay vote on compensation paid to its named executive officers.

This Supplement is being furnished to our shareholders of record at the close of business on April 15, 2024, the record date for the determination of shareholders entitled to attend the AGM. This Supplement supplements and amends the Proxy Statement, dated April 26, 2024, previously made available to our shareholders. This Supplement does not provide all of the information that is important to your decision at the AGM. Additional information is included in the Proxy Statement that was previously made available to our shareholders. We encourage you to carefully read this Supplement together with the Proxy Statement.

We urge shareholders of record to vote on Proposals 1 through 12 by following the methods described in the Proxy Statement. Please note that, if you vote again, it will revoke all proxies previously submitted. Accordingly, it is important to indicate your vote on each proposal.

If you are a shareholder of record and you execute and return a new proxy but do not give instructions, your proxy will be voted “FOR” all nominees set forth in Proposal 1, “FOR” Proposals 2-11 and “1 YEAR” for Proposal 12.

If you have already voted and do not take further action, your previously submitted proxy will be voted at the AGM with respect to Proposals 1-11 but will not be counted in determining the outcome of Proposal 12.

Except for the addition of Proposal No. 12, this Supplement does not modify, amend, supplement or otherwise affect any matter presented for consideration in the Proxy Statement.
