Insights

Securities Compliance Specialist

Amendment corrects a reporting error and reconfirms disclosed holdings.

The amendment states a corrected beneficial ownership total of 4,328,045 shares and reiterates the filing is a remedial update to a prior 13G/A. The percentage is calculated using 36,438,703 shares outstanding as of May 12, 2026.

The note conversion detail—952,381 shares convertible at $1.05—is material to the composition of the position; timing and cash‑flow treatment of any conversion are not described in the excerpt.

Investor Relations Analyst

This is an ownership disclosure, not an active trading event.

The filing clarifies beneficial ownership and confirms no transactions since the prior filing dated May 11, 2026. The disclosed split between held shares and convertible note interest helps explain potential future dilution if conversion occurs.

Subsequent filings would be needed to show any conversion or sale activity; cash‑flow treatment from conversion is not provided in the excerpt.

Schedule 13G/A regulatory

"Amendment No. 2 to a Schedule 13G/A states that Francisco Trust beneficially owns"

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.

beneficially owned financial

"Amount beneficially owned: 4,328,045.00 (b) Percent of class: 11.58 %"

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.

convertible promissory note financial

"issuable upon conversion of a convertible promissory note issued on March 8, 2024"

A convertible promissory note is a loan a company takes now that can later be turned into shares instead of being repaid in cash. Think of it as lending money with the option to accept ownership in the business down the road; that matters to investors because it affects who gets paid first, how much ownership existing shareholders keep, and the company’s future valuation and cash needs. Terms such as conversion price, interest and maturity determine the financial impact.

conversion price financial

"Such note, as amended, is convertible at a per share price of $1.05"

The conversion price is the fixed price at which a convertible security, like a bond or preferred stock, can be exchanged for shares of common stock. It acts like a set rate that determines how many shares an investor can receive if they choose to convert their investment. This helps investors understand the value and potential benefits of converting their securities into company shares.
