Filing Released Lang Actions
S-1
Capital/Financing Update Classification · 85% confidence The document is a Form S-1 registration statement and preliminary prospectus under the Securities Act of 1933, detailing the planned sale of over 24 million shares of common stock by selling stockholders, the plan of distribution, risk factors, use of proceeds, and related financing terms. It is not a general regulatory announcement or a simple notice but a full capital raising document. Under our taxonomy, this best fits “Capital/Financing Update (CAP).”

424B3
Capital/Financing Update Classification · 85% confidence The document is a prospectus supplement filed under Rule 424(b)(3) updating a Registration Statement on Form S-1 and disclosing pro forma financial information in a Current Report on Form 8-K. It relates directly to a securities offering, amendment of prospectus details, and capital structure changes. This is a financing update rather than an annual or interim financial report or regulatory certification. Therefore it falls under Capital/Financing Update (CAP).

424B3
Capital/Financing Update Classification · 87% confidence The document is a Rule 424(b)(3) prospectus supplement to a Form S-1 registration statement, filed as a Current Report on Form 8-K, describing amendments to a securities offering and pro forma financials in connection with a rights offering and debt-for-equity exchanges. It is clearly focused on capital-raising and changes to the company’s capital structure rather than an annual or interim report, call transcript, or management discussion. Therefore it is classified as a Capital/Financing Update.
2026-06-09 English
8-K
Report Publication Announcement Classification · 83% confidence The document is a Form 8-K current report under the Exchange Act that discloses the attachment of unaudited pro forma financial information as Exhibit 99.1. The body contains no substantive financial statements but simply notes the report is attached. At only ~4,000 characters and stating that the report is attached, it fits the “menu vs meal” rule for a report publication announcement rather than the report itself. Therefore, it should be classified as an RPA.
2026-06-09 English
SD
Regulatory Filings Classification · 95% confidence The document is an SEC Form SD (Specialized Disclosure Report) filed under Rule 13p-1 for Conflict Minerals Disclosure. It contains no financial statements or audit findings but is a regulatory compliance filing. Form SD is not a full annual or interim report but a specialized regulatory submission, so it falls into the general Regulatory Filings category (RNS).
