Filing Explained

The amendment clarifies that the Trust’s 3,000,000 reported common shares are conversion shares issuable from 3,000 Series A preferred shares, not a completed common-stock issuance; if conversion occurs, the added shares would reduce existing holders’ percentage ownership absent offsetting changes.

beneficial owner financial
"As of August 12, 2026, Benchmark was the record beneficial owner of 650,000 Shares"
A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.
Series A Convertible Preferred Stock financial
"3,000 shares of Series A Convertible Preferred Stock of the Issuer that are convertible"
Series A convertible preferred stock is a class of shares sold in an early funding round that gives investors a mix of protection and upside: it pays a priority claim over common shares if the company is sold or closes, but can be converted into ordinary shares to share in future growth. Think of it like a hybrid between a safer stake and a ticket to ownership; it matters to investors because it affects who controls the company, how future gains are split, and how much their investment is protected from downside.
private placement financial
"all of which were purchased by Benchmark on October 30, 2025 in a private placement"
A private placement is a sale of securities directly to a selected group of investors, typically institutions or accredited investors, instead of through a public offering. It lets a company raise money faster and with fewer regulatory steps; for existing shareholders it matters because the newly issued shares, often sold at a discount, increase the share count and can dilute their ownership.
board observer agreement regulatory
"entered into a series A securities purchase agreement and a separate a board observer agreement"
conversion rights financial
"The Purchase Agreement set forth the terms and conditions ... including the conversion and voting rights"
Conversion rights are a contract feature that lets the holder change one kind of security—often a bond or preferred share—into another, typically common stock, at a predetermined rate. Investors care because conversion can provide upside if the stock rises (like swapping a ticket for a better prize), but it can also dilute existing shareholders and change ownership and voting power, affecting share value and strategy.
