B. Riley Principal Investments, LLC
CIK 0001776226 Name as filed on the most recent filing
Filed as B. Riley Principal Investments, LLC (52)
200 transaction lines · from 52 filings · filed 2019-11-01 to 2023-12-04 The span is the filing dates this catalog holds, not the entity's full filing history. Absence here is not evidence of absence at the SEC.
A line appears here when the filing that carries it names this CIK as a reporting owner, not only when the parser picked this CIK as the line's primary owner. That is why a joint filing appears on both owners' pages rather than vanishing from the second one. The catalog never merges two CIKs into one person and never splits one CIK into two: identity here is the SEC's own identifier and nothing else.

This column is intentionally blank
No transaction line is stored for this reporting owner, though the catalog holds filings naming them. That happens when the filings report only holdings or only positions the store does not carry, and when a parse failed; each filing page states its own parse status.
- P, Open-market purchase
- Open-market purchase
- S, Open-market sale
- Open-market sale
Every value is as reported on the Form 4. A price the filing did not report is marked Not reported and no value is computed from it. Codes outside the open market, drawn in grey behind a dashed rule, are compensation and administrative machinery rather than a decision to trade at the prevailing price.
What this insider's stored lines contain
No transaction line is stored for this entity, so there is nothing to break down by code. The catalog holds its filings; what it does not hold is a single reportable line from them, which is a fact about the parse and about these filings, not about the entity.
