Here are the S-1 registration statements from CitroTech Inc. (CITR) in our archive over the last 12 months, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
An S-1 covers the registration statement a company files to sell shares publicly, so if you follow CITR and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full CITR filings page.

CitroTech Inc. (CITR) is offering 1,639,344 shares of common stock on a firm-commitment basis for up to $7.0 million, at an assumed $4.27 per share; the actual price may be at, above or below that assumption. Shares may not be sold until the registration statement becomes effective. CitroTech estimates net proceeds of approximately $6.3 million, or approximately $7.3 million if the underwriters exercise their full option, for working capital and general corporate purposes.

For the six months ended June 30, 2026, CitroTech reported a $10.1 million net loss, compared with approximately $22.8 million in the year-earlier period, and an accumulated deficit of $123.3 million.

CitroTech Inc. is registering up to 8,154,280 shares of common stock for resale by existing stockholders.

CitroTech will not receive cash from these resales, but may receive funds if warrants covered by the prospectus are exercised.
The company had 18,803,230 shares outstanding as of February 16, 2026, with a stated total of 26,957,510 shares outstanding after the offering.

The business is highly leveraged, with about $2.49 million of debt as of December 31, 2025, and depends on a small number of customers and a five-person management team. Two preferred stockholders control roughly 99% of voting power through super-voting Series A preferred shares, qualifying CitroTech as a “controlled company” that uses NYSE American governance exemptions. The prospectus highlights significant risks, including volatile share price, potential dilution from preferred stock, warrants and options, regulatory and product-liability exposure in fire-retardant markets, and the need for continued external financing.
