beneficial ownership regulatory
"Reference to "beneficial ownership" of securities for purposes of this statement"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
Rule 13d-3 regulatory
"beneficial ownership as that term is defined in Rule 13d-3 of the Securities Exchange Act"
Rule 13d-3 defines who is treated as the beneficial owner of a company’s shares for U.S. securities disclosure rules — essentially anyone who has the power to vote or direct how shares are voted, or the power to buy or sell them, even if they don’t hold the certificates. For investors this matters because crossing certain ownership thresholds triggers public filing and disclosure obligations and signals potential control or influence, much like having the keys to a car implies you can drive it even if it’s registered to someone else.
Schedule 13G/A regulatory
"The percentage reported in Row 11 was calculated in accordance with Rule 13(d)-3(d)(1)(i) promulgated"
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.
GRAT financial
"Venturo Family 2024 Friends and Family GRAT (the "F&F GRAT")"
GST Exempt Trust financial
"Venturo Family GST Exempt Trust dated June 30, 2023 (the "GST Exempt Trust")"
dispositive power financial
"Sole Dispositive Power 9,992,957.00 8 | Shared Dispositive Power 7,006,036.00"
Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
