beneficially owned financial

"the aggregate number and percentage of the shares ... that are beneficially owned by the Reporting Person"

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 financial

"Number of Shares Beneficially Owned by Each Reporting Person With: 7 Sole Voting Power 235,482.00"

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.

shared dispositive power financial

"10 Shared Dispositive Power 2,000.00"

restricted shares financial

"On June 9, 2025, Mr. Heilbron was granted 20,000 restricted shares that will vest annually"

Restricted shares are company stock that cannot be sold or transferred immediately because they are subject to legal or contractual limits, such as a required holding period or performance conditions. They matter to investors because these locked-up shares can affect a company’s available stock for trading, future dilution, and insider incentives—imagine a gift that can’t be cashed until certain conditions are met, which changes when and how much supply can suddenly enter the market.

tradeable warrants financial

"used $62.42 in personal funds to purchase 1,900 tradeable warrants"

Tradeable warrants are market-traded securities that give the holder the right, but not the obligation, to buy a company's shares at a set price before a specific date—think of them as time-limited coupons for future stock purchases that you can also buy or sell on an exchange. They matter to investors because they offer leveraged exposure to a stock’s move and are easier to trade than private options, but they can dilute existing shareholders if exercised and can lose value quickly as the expiry approaches.

warrants financial

"Each warrant is exercisable into 1/10 of a share."

Warrants are special documents that give you the right to buy a company's stock at a set price before a certain date. They are often used as a way for companies to attract investors or raise money, and their value can increase if the company's stock price goes up.
