beneficially owned financial

"Item 4. | Ownership (a) | Amount beneficially owned: 706207"

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.

shared voting power financial

"Shared Voting Power 706,207.00 7 | Sole Dispositive Power 0.00 8 | Shared Dispositive Power 706,207.00"

Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.

shared dispositive power financial

"8 | Shared Dispositive Power 706,207.00 9 706,207.00"

fully discretionary basis financial

"shares reported by Driehaus Capital Management LLC (DCM) are held by numerous clients on a fully discretionary basis"

percent of class financial

"Item 4. | Ownership (a) | Amount beneficially owned: 706207 (b) | Percent of class: 7.18%"

Percent of class is the portion of a specific category of securities—such as a company’s common shares, preferred shares, or a bond series—that takes part in or approves a corporate action (vote, consent, tender, etc.). Investors watch this number because it reveals how much support or opposition exists within that particular shareholder group; like counting how many members of a club back a proposal, it can determine whether a plan passes or how influence is distributed.
