All stockholders who do not receive a Notice of Internet Availability, or who have not consented to receive their proxy materials electronically by email, will be mailed a paper copy of the proxy materials. Furnishing proxy materials over the Internet allows us to provide our stockholders with the information they need in a timely manner, while reducing the environmental impact and lowering the costs of printing and distributing our proxy materials.

On behalf of our Board of Directors, I cordially invite all stockholders to attend the Meeting. It is important that your shares be voted on the matters scheduled to come before the Meeting. Whether or not you plan to attend the Meeting, I urge you to vote your shares. We encourage you to vote your proxy by mailing in your enclosed proxy card in the enclosed postage-paid envelope or vote online or over the telephone according to the instructions in the proxy card. If you attend the Meeting, you may revoke such proxy and vote in person if you wish. Even if you do not attend the Meeting, you may revoke such proxy at any time prior to the Meeting by executing another proxy bearing a later date or providing written notice of such revocation to the Chief Executive Officer of the Company.

Date: October 23, 2026 BY ORDER OF THE BOARD OF

Chief Executive Officer, Principal Executive Officer and Director

This Proxy Statement and the accompanying proxy card are being furnished with respect to the solicitation of proxies by the Board of Directors (the "Board") of LiqTech International, Inc., a Nevada corporation (the "Company" or "LiqTech"), for the Annual Meeting of the Stockholders (the "Meeting") to be held at 3:00 p.m. local time on Thursday, December 3, 2026, and at any adjournment or adjournments thereof, at the corporate headquarters of the Company at Industriparken 22C, DK2750 Ballerup, Denmark.

For the Meeting, we have elected to furnish our proxy materials, including this proxy statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, as amended (the "Annual Report"), to our stockholders primarily via the internet. On or about October 23, 2026, we expect to mail to our stockholders a Notice of Internet Availability of Proxy Materials (the "Notice") that contains notice of the Meeting and instructions on how to access our proxy materials on the internet, how to vote at the Meeting and how to request printed copies of the proxy materials.

These proxy materials are available free of charge on the internet at www.proxyvote.com. Stockholders are invited to attend the Meeting to vote on the proposals described in this Proxy Statement. However, stockholders do not need to attend the Meeting to vote. Instead, stockholders may simply complete, sign and return the proxy card in the enclosed postage-paid envelope or vote online or over the telephone according to the instructions in the proxy card.

We will bear the expense of solicitation of proxies for the Meeting, including the printing and mailing of this Proxy Statement. We may request persons, and reimburse them for their expenses with respect thereto, who hold stock in their name or custody or in the names of nominees for others to forward copies of such materials to those persons for whom they hold Common Stock (as defined below) and to request authority for the execution of the proxies. In addition, some of our officers, directors and employees, without additional compensation, may solicit proxies on behalf of the Board personally or by mail, telephone or facsimile.

Only stockholders of record of the Company's common stock, $0.001 par value (the "Common Stock"), as of the close of business on October 7, 2026 (the "Record Date") are entitled to notice and to vote at the Meeting and any adjournment or adjournments thereof.

As of the Record Date, there were 32,947,841 shares of Common Stock outstanding. Each holder of Common Stock on the Record Date is entitled to one vote for each share then held on the matters to be voted at the Meeting. No other class of voting securities was then outstanding.

The presence at the Meeting of the persons entitled to vote a majority of the issued and outstanding shares of Common Stock as of the Record Date, in person or by proxy, is required for a quorum. Should you submit a proxy, even though you abstain as to a proposal, or you are present in person at the Meeting, your shares shall be counted for the purpose of determining if a quorum is present.

Broker "non-votes" are included for the purposes of determining whether a quorum of shares is present at the Meeting. A broker "non-vote" occurs when a nominee holder, such as a brokerage firm, bank or trust company, holding shares of record for a beneficial owner, does not vote on a particular proposal because the nominee holder does not have discretionary voting power with respect to that item and has not received voting instructions from the beneficial owner. Proposal 1 is considered a non-routine matter, and a broker or other nominee holder cannot vote without instructions on non-routine matters. Consequently, we expect broker non-votes with respect to Proposal 1. Proposal 2 is considered a routine matter, and a broker or other nominee holder is permitted to vote on routine matters without instructions.

The election of directors is by plurality vote. Withholding authority to vote your shares with respect to one or more director nominees and broker non-votes will have no effect on the outcome of Proposal 1. Proposal 2 requires the approval of a majority of votes cast in person or by proxy at the meeting. Abstentions and non-broker votes will have no effect on the outcome of Proposal 2.

If you are the beneficial owner, but not the registered holder of our shares of Common Stock, you cannot directly vote those shares at the Meeting. You must provide voting instructions to your nominee holder, such as your brokerage firm or bank, by following the specific directions provided to you by your nominee holder.

If you wish to vote in person at the Meeting but you are not the record holder, you must obtain from your record holder a "legal proxy" issued in your name and bring it to the Meeting. At the Meeting, ballots will be distributed with respect to the proposals to each stockholder (or the stockholder's proxy if not the management proxy holders) who is present and did not deliver a proxy to the management proxy holders or another person. The ballots shall then be tallied, one vote for each share owned of record as follows:

● the votes on the election of directors being either "FOR ALL", "WITHHOLD ALL"or"FOR ALL EXCEPT" (where stockholders may withhold such vote by writing the names of such nominee(s) in a space provided on the ballot); and

● the votes on Proposal 2 being either "FOR," "AGAINST"or"ABSTAIN".

The form of proxy solicited by the Board affords you the ability to specify a choice among approval of, disapproval of, or abstention with respect to, the matters to be acted upon at the Meeting. Shares represented by the proxy will be voted, and where the solicited stockholder indicates a choice with respect to the matter to be acted upon, the shares will be voted as specified. If no choice is given, a properly executed proxy will be voted in favor of the proposals.

Even if you execute a proxy, you retain the right to revoke it and change your vote by notifying us at any time before your proxy is voted. Such revocation may be effected by execution of a subsequently dated proxy, or by a written notice of revocation, sent to the attention of the Chief Executive Officer (the "CEO") of the Company at the address of the corporate headquarters of the Company set forth above in the Notice to this Proxy Statement or your attendance and voting at the Meeting. Unless so revoked, the shares represented by the proxies, if received in time, will be voted in accordance with the directions given therein.

You are requested, regardless of the number of shares you own or your intention to attend the Meeting, to sign the proxy and return it promptly in the enclosed envelope or vote online or over the telephone according to the instructions in the proxy card.
