There are no detailed financial statements or comprehensive financial data presented, only a regulatory update about listing compliance.

PRE 14A
Proxy Solicitation & Information Statement Classification · 100% confidence The document is a Schedule 14A proxy statement filed with the SEC for a Special Meeting of Stockholders of Soluna Holdings, Inc. It includes detailed information about the meeting agenda, voting procedures, record date, and proxy solicitation. The document is not an annual report, earnings release, or financial statement, but rather a solicitation of shareholder votes on specific proposals, including an amendment to increase authorized shares and an adjournment proposal. The presence of the term 'Proxy Statement' and the form type 'PRE 14A' clearly identifies this as a Proxy Solicitation & Information Statement. The document length (15,000 characters) and content confirm it is the full proxy statement, not just an announcement or notice. Therefore, the correct classification is Proxy Solicitation & Information Statement (PSI).

S-3
Capital/Financing Update Classification · 95% confidence The document is a Form S-3 Registration Statement filed with the SEC, dated September 26, 2025, for Soluna Holdings, Inc. It is a registration statement under the Securities Act of 1933, used for registering securities for public sale. The text includes a preliminary prospectus describing the offering of warrants and common stock, details about the company, and the terms of the offering.

Therefore, it fits the category of Capital/Financing Update (CAP).
