beneficial ownership financial

"aggregate amount beneficially owned by each reporting person"

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.

restricted stock financial

"75,951 shares of restricted stock held by the Reporting Person"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

Uniform Transfer to Minors Act regulatory

"Uniform Transfer to Minors Act ("UTMA") account"

Effective Time regulatory

"At the effective time of the Merger ("Effective Time")"

The exact clock time when a regulatory filing, approval, or corporate action formally becomes legally active; from that moment the change is binding and can be acted on. Investors care because the effective time marks when ownership, rights, trading rules, or new securities take effect — like a light switch turning on a contract or transaction — which determines when risks, benefits and market reactions begin.
