Restricted Stock Agreement financial
"will vest on the earlier of the 2027 Annual Meeting...subject to the terms of the Restricted Stock Agreement"
non-employee director financial
"granted to Jeffrey Altman as compensation for his services as a non-employee director"
beneficial ownership financial
"disclaims beneficial ownership of the securities to which this filing relates"
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.
pecuniary interest financial
"except to the extent of his or its pecuniary interest therein, if any"
