PRELIMINARY PROSPECTUS, SUBJECT TO COMPLETION, DATED FEBRUARY 17, 2026

Up to 8,154,280 Shares of Common Stock

This prospectus relates to the resale from time to time by the selling stockholders named in this prospectus (the “Selling Stockholders”) of up to 8,154,280 shares (the “Shares”) of common stock, par value $0.0001 per share, (“Common Stock”) of CitroTech Inc., a Wyoming corporation (the “Company,” “CITR,” “we,” “us,” or “our”), which includes (i) 2,383,391 shares of Common Stock issuable upon conversion of 688,922 shares of Series C preferred stock (“Series C Preferred Stock”) held directly or indirectly by the Selling Stockholders issued to investors in a private placement offering on September 30, 2025 (the “September 2025 Private Placement”) and subsequent private placement offering on October 21, 2025 (the “October 2025 Private Placement” and together, with the September 2025 Private Placement, the “2025 Private Placements”); (ii) 2,383,391 shares of Common Stock issuable upon the exercise of warrants issued to investors in the 2025 Private Placements, (iii) an aggregate of 1,042,711 shares of Common Stock issued to debtholders upon the conversion of convertible debt and (iv) 2,431,752 shares of Common Stock.

The Shares will be resold from time to time by the Selling Stockholders listed in the section titled “Selling Stockholder” beginning on page 78.

The Selling Stockholders, or their respective transferees, pledgees, donees or other successors-in-interest, will sell the Shares through public or private transactions at prevailing market prices, at prices related to prevailing market prices or at privately negotiated prices. The Selling Stockholders may sell any, all or none of the Shares offered by this prospectus, and we do not know when or in what amount the Selling Stockholders may sell their Shares hereunder following the effective date of this registration statement. We provide more information about how Selling Stockholders may sell their Shares in the section titled “Plan of Distribution” on page 80.

We are registering the Shares on behalf of the Selling Stockholders, to be offered and sold by them from time to time. We will not receive any proceeds from the sale of the Shares by the Selling Stockholders; however we may receive proceeds upon the exercise of outstanding warrants for shares of Common Stock covered by this prospectus. We have agreed to bear all of the expenses incurred in connection with the registration of the Shares. The Selling Stockholders will pay or assume discounts, commissions, fees of underwriters, selling brokers or dealer managers and similar expenses, if any, incurred for the sale of the Shares.

On April 15, 2025, our Board of Directors and our stockholders that have a majority of our voting power approved an amendment to our articles of incorporation (as amended, the “Articles of Incorporation”) to effect the reverse stock split (which includes the outstanding Series A Preferred Stock and Common Stock of the Company at a 1-for-6 ratio). The reverse stock split was effective on August 27, 2025 the (“Reverse Stock Split”). The share and per share data presented herein have been retroactively adjusted to reflect the Reverse Stock Split.

Our Common Stock is currently listed on the NYSE American LLC (“NYSE American”) under the symbol “CITR.” On February 13, 2026, the last reported sale price of our common stock was $7.33 per share.

We are a “smaller reporting company” as defined under the federal securities laws and, as such, we have elected to comply with certain reduced reporting requirements for this prospectus and may elect to do so in future filings. See “Risk Factors”, and “Prospectus Summary - Implications of Being a Smaller Reporting Company.”

We are a “Controlled Company” as defined under the listing rules of NYSE American because, and as long as, Mr. Theodore Ralston, our Chairman of the Board of Directors, holds more than 50% of the Company’s outstanding voting power, he will exercise control over the management and affairs of the Company and matters requiring stockholder approval, including the election of the Company’s directors. For so long as we remain a Controlled Company under that definition, we are permitted to elect, and intend, to rely on certain exemptions from the corporate governance rules of NYSE American, including:

Investing in our Common Stock involves risks. See “Risk Factors” beginning on page [11].

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.
