Filing Released Lang Actions
FORM 8-K
Capital/Financing Update Classification · 85% confidence The document is a Form 8-K current report disclosing a Debt Cancellation Agreement that converts $3.0 million of senior notes into equity and settles the remainder in cash, along with an unregistered share issuance under Section 4(a)(2). This clearly concerns financing activities and a material capital structure change rather than an earnings release or legal proceeding. It therefore best fits the Capital/Financing Update category.
2026-06-01 English
FORM S-1/A
Regulatory Filings Classification · 95% confidence The document is a Form S-1/A registration statement and preliminary prospectus filed with the U.S. SEC under the Securities Act of 1933, detailing the offering of common stock and warrants. It is not an Annual Report (10-K), Earnings Release, or any AGM/EGM disclosure, nor is it a proxy statement or any management/board change announcement. It is a regulatory filing of a securities offering (an S-1 registration). Since it does not fit any more specific category, it falls under the fallback category “Regulatory Filings (RNS).”

FORM S-1
Regulatory Filings Classification · 87% confidence The document is a Form S-1 registration statement and preliminary prospectus filed with the U.S. Securities and Exchange Commission under the Securities Act of 1933 for LiqTech International, Inc. It outlines the terms of a securities offering (common stock, warrants, underwriter arrangements), but does not constitute a general annual or quarterly financial report, nor does it report earnings results, governance changes, legal proceedings, or an AGM presentation. It is a regulatory compliance filing for a securities offering and hence falls under the general “Regulatory Filings” category (RNS) as the closest match.

FORM 8-K
Capital/Financing Update Classification · 85% confidence The document is a U.S. SEC Form 8-K “Current Report” describing the Company’s issuance and sale of promissory notes – a financing event detailing new debt obligations. This fits the definition for a Capital/Financing Update (CAP).
