Compass Diversified Holdings

Shareholders of Record. We encourage you to appoint a proxy to vote on your behalf by submitting a proxy via the Internet or telephone or by promptly submitting the enclosed proxy card, which is solicited by the Company’s Board, and which, when properly completed, signed, dated and returned to us, will ensure that your shares are voted as you direct. We strongly encourage you to submit a proxy regardless of whether you will attend the Annual Meeting to ensure that your vote is represented at the Annual Meeting.

PLEASE RETURN YOUR PROXY CARD TO US IN THE ACCOMPANYING ENVELOPE, OR SUBMIT YOUR VOTE BY TELEPHONE OR ONLINE, NO LATER THAN 11:59 P.M., EASTERN TIME, ON MAY 20, 2026. IF WE DO NOT RECEIVE YOUR PROXY CARD OR VOTE BY THAT TIME, YOUR PROXY WILL NOT BE VALID. IN THIS CASE, UNLESS YOU ATTEND AND VOTE YOUR SHARES ELECTRONICALLY AT THE ANNUAL MEETING, YOUR VOTE WILL NOT BE REPRESENTED.

The persons named in the proxy card are officers of the Company and have been designated as proxies by our Board. These designated proxies will vote as directed by the completed proxy card.

If you wish to change your vote, you may do so by revoking your proxy before the Annual Meeting. Please see the section titled “Revocation of Proxy” below for more information.

Beneficial Owners. If you hold your shares in street name, these Proxy Materials are being forwarded to you by your bank, broker or their appointed agent. If you requested printed copies of these Proxy Materials, you should also have received a voter instruction card instead of a proxy card. Your bank or broker will vote your shares as you instruct on the voter instruction card. We strongly encourage you to promptly complete and return your voter instruction card to your bank or broker in accordance with their instructions so that your shares are voted. You may also request a legal proxy from your bank or broker to vote electronically at the Annual Meeting.

Voting by the Designated Proxies

The persons who are the designated proxies will vote as you direct in your proxy card or voter instruction card. Please note that proxy cards returned without voting directions, and without specifying a proxy to attend the Annual Meeting and vote on your behalf, will be voted by the designated proxies in accordance with the recommendations of our Board. Our Board recommends:

If any other matter properly comes before the Annual Meeting, your proxies will vote on that matter in their discretion.
