Insights

Corporate Governance Analyst

Trust discloses a meaningful passive stake and a renegotiated convertible position.

Francisco Trust reports 4,363,045 shares beneficially owned and sole voting power over 3,410,664 shares. The filing clarifies voting and dispositive powers, which matter for shareholder votes.

The Convertible Note amendment reduced the conversion price to $1.05 and extended maturity to 12/31/2027; this changes potential dilution timing and conversion economics. Subsequent filings will show whether conversion is exercised.

Capital Markets Analyst

Amendment adjusts convertible economics and reports position relative to outstanding shares.

The filing lists 952,381 shares underlying the Convertible Note and an aggregate share base of 36,438,703 as of 03/24/2026. The conversion price change to $1.05 from $1.40 increases the note-holder's per-share exposure if converted.

Cash‑flow treatment and any planned conversions are not disclosed in this excerpt; future filings may state transactions if they occur.

Key Terms

4 terms

Convertible Note financial

"The Convertible Note was amended on December 23, 2025"

A convertible note is a type of loan that a company gets from investors, which can later be turned into company shares instead of being paid back in cash. It matters because it helps startups raise money quickly without setting a fixed value for the company right away, making it easier to grow and attract investors.

beneficially owned regulatory

"Amount beneficially owned: 4,363,045"

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.

sole voting power governance

"The Reporting Person has sole voting power over 3,410,664 shares"

Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.

Schedule 13G/A regulatory

"Item 1. Name of issuer: DYADIC INTERNATIONAL INC"

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.
