Filing Released Lang Actions
FORM SD
Regulatory Filings Classification · 86% confidence The provided document is a Form SD (Specialized Disclosure Report) relating to conflict minerals disclosure. It is an SEC compliance filing with exhibits, not an annual or interim financial report, earnings release, management discussion, or any other specialized category. It does not contain substantive financial statements but rather a regulatory disclosure. Therefore, it falls under the generic “Regulatory Filings” category.
2026-05-29 English
8-K
Capital/Financing Update Classification · 91% confidence The document is a Form 8-K reporting entry into an underwriting agreement for the issuance and sale of equity shares, detailing the terms of the offering, underwriting arrangements, and proceeds. This constitutes a capital fundraising and financing activity update rather than a simple governance, earnings, or report publication notice. Therefore, it fits the Capital/Financing Update category.
2026-05-15 English
424B5
Capital/Financing Update Classification · 92% confidence The document is a prospectus supplement filed under Rule 424(b)(5) describing an offering of 4,568,308 common shares (1,261,384 primary and 3,306,924 secondary) by PDF Solutions and a selling stockholder, with underwriting details, use of proceeds, risk factors, and financial summaries. This is clearly a fundraising / financing transaction—an equity issuance prospectus—rather than an annual report, earning release, or management call transcript. It updates on a capital raise and change in capital structure, matching the definition for Capital/Financing Update (CAP).

8-K - PDF SOLUTIONS INC (0001120914) (Filer)
Capital/Financing Update Classification · 95% confidence The document is a Form 8-K Current Report filed with the SEC, dated April 23, 2026. It announces the entry into a material definitive agreement, specifically a First Amendment to a Credit Agreement that increases the revolving credit facility and adjusts commitment fees based on leverage ratios. The document does not contain financial statements or detailed financial analysis but rather reports a financing event and amendment to credit terms. This fits the category of Capital/Financing Update (CAP), which covers updates on company fundraising, financing activities, or capital structure changes. The document length is about 4842 characters, which is sufficient for a detailed announcement but not a full financial report. Therefore, the correct classification is CAP with high confidence.
