Consolidated Water Co Ltd

This Proxy Statement has been prepared and is distributed and made available by the board of directors (the “Board of Directors”) of Consolidated Water Co. Ltd. (the “Company”) in connection with the solicitation of proxies for the Annual General Meeting of Shareholders of the Company (the “Annual General Meeting”) to be held at The Westin Grand Cayman Seven Mile Beach Resort & Spa, Seven Mile Beach, Grand Cayman, Cayman Islands, at 3:00 p.m. Cayman Islands time (4:00 p.m. Eastern Daylight Time), on Tuesday, May 27, 2025, and any adjournment or postponement thereof for the purpose set forth in the accompanying Notice of Annual General Meeting of Shareholders. Shareholders will need to have the 16-digit control number included on their Notice of Internet Availability, their proxy card or the instructions that accompany their proxy materials to be admitted to the Annual General Meeting.

This Proxy Statement and the accompanying form of proxy will be distributed to shareholders and will be made available for viewing, downloading and printing by shareholders atwww.proxyvote.com, on or about April 17, 2025. The Company will bear the cost of the solicitation of proxies.

Only holders of record of the Company’s Ordinary Shares, par value CI$0.50 per share (the “Ordinary Shares”), and the Company’s Redeemable Preference Shares, par value CI$0.50 per share (the “Redeemable Preference Shares”), on the books of the Company at the close of business on March 28, 2025, are entitled to vote at the Annual General Meeting. On that date, 15,916,685 Ordinary Shares and 40,830 Redeemable Preference Shares were issued and outstanding. Our Ordinary Shares and Redeemable Preference Shares are referred to as “common stock” and “redeemable preferred stock,” respectively, in our consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America. All matters that come before this Annual General Meeting will be decided by a vote that will be demanded in each case by Frederick W. McTaggart or David W. Sasnett, the persons who are appointed proxies in the proxy card which accompanies this Proxy Statement. Each shareholder of record is entitled to one vote for each Ordinary Share or Redeemable Preference Share (collectively, the “Shares”) on all matters that come before the Annual General Meeting. The holders of 331∕3% of the issued and outstanding Shares, present in person or represented by proxy, will constitute a quorum for the transaction of business at the Annual General Meeting.

For Proposal 1, the election of eight directors, each nominee shall be elected as a director if the number of Shares cast “for” such nominee’s election exceeds the number of Shares “withheld” with respect to such nominee’s election. The approval of holders of at least a majority of the Shares cast is required for: (i) Proposal 2, the advisory vote on executive compensation; and (ii) Proposal 3, the ratification of the selection of CBIZ as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2025.

Proposal 1 (the election of eight directors) and Proposal 2 (the advisory vote on executive compensation) are considered “non-routine” matters. Proposal 3 (the ratification of the appointment of CBIZ as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2025) is considered a “routine” matter. Banks, brokers, or other nominees (“Brokers”) who hold shares on behalf of beneficial shareholders have discretion to vote such shares with respect to “routine” matters without receiving voting instructions from the beneficial holders of the shares. However, Brokers who hold shares on behalf of beneficial shareholders do not have discretion to vote such shares with respect to “non-routine” matters if they do not receive voting instructions from the beneficial holders of the shares. If no instruction is given to Brokers with respect to “non-routine” matters, a “broker non-vote” is recorded for each such uninstructed share. Abstentions and “broker non-votes” are not treated as votes cast and, therefore, will not affect the outcome of the vote.

Shares represented by a properly executed proxy must be received not later than 24 hours before the scheduled time of the meeting and, if received in time to permit its use at the meeting or any postponement or adjournment thereof, will be voted in accordance with the instructions indicated therein. If no instructions are

​

indicated, the Shares represented by the proxy will be voted (i) “for all” in the election of the nominees for director; (ii) “for” the approval of executive compensation; and (iii) “for” the ratification of the selection of CBIZ as the Company’s independent registered public accounting firm.

A shareholder of record who has given a proxy may revoke it at any time before it is voted at the meeting by giving written notice of such revocation to the office of the Secretary of the Company, or by executing and delivering to the Company not later than 24 hours before the scheduled time of the meeting a proxy bearing a later date. A proxy will be revoked automatically if a shareholder attends the meeting.
