Insights

Governance Analyst

Disclosure shows passive ownership below 5% with shared voting/dispositive power.

The filing documents that Dellora Investments Master Fund LP holds 345,257 shares and Dellora Investments LP and Kevin Pyun each report 394,665 shares, tied to shared voting and dispositive authority. The percentages are calculated from 17,197,613 shares outstanding as of March 6, 2026.

Because the filing is a Schedule 13G/A with an express disclaimer under Rule 13d-4, it indicates a passive reporting context; subsequent filings would disclose any change in status or percent exceeding 5%.

Compliance Counsel

Statement includes formal disclaimers and standard adviser attribution language.

The disclosure explains that Dellora Investments LP acts as an investment adviser to funds and that Mr. Pyun may be deemed to have voting and dispositive power, while expressly disclaiming beneficial ownership under Rule 13d-4. Signatures are provided by Kevin Pyun as Principal.

Filing-type implications: this is a disclosure filing; it does not report transactions or changes in ownership methodology. Future Form 13 filings would be required if passive/active status changes.

4 terms

Schedule 13G/A regulatory

"Amended Schedule 13G/A reporting beneficial ownership"

A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.

Rule 13d-4 regulatory

"expressly disclaim beneficial ownership under Rule 13d-4"

shared dispositive power financial

"Shared Dispositive Power 394,665.00 reported for Dellora Investments LP"

beneficially owned regulatory

"Amount beneficially owned: Dellora Investments LP may be deemed to be the beneficial owner"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
