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, if you received paper copies of the Proxy Materials, 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 PROVIDED POSTAGE PRE-PAID ENVELOPE, OR SUBMIT YOUR VOTE BY TELEPHONE OR ONLINE, NO LATER THAN 11:59 P.M., EASTERN TIME, ON MAY 28, 2025. 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 below under the heading“Revocation of Proxy” 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.

Revocation of Proxy

If you are a shareholder of record, you may revoke or change your proxy before it is voted by providing notice of revocation to our Corporate Secretary, by delivering a proxy bearing a later date or by attending and voting at the Annual Meeting. Attendance at the Annual Meeting will not cause your previously granted proxy to be revoked unless you specifically make that request. If you are a beneficial owner of shares, you may submit new voting instructions by contacting your bank, broker or other record holder or, if you obtained a legal proxy from your bank, broker or other record holder giving you the right to vote your shares, by attending and voting at the Annual Meeting.

Any written notice of revocation must be sent to Compass Group Diversified Holdings LLC, 301 Riverside Avenue, Second Floor, Westport, Connecticut 06880 or by facsimile to (203) 221-8253, to the attention of Carrie W. Ryan, Secretary.
