pro rata distribution financial

"Pro rata distribution from NorthView Sponsor I LLC, of which the reporting person is a manager."

A pro rata distribution is when a company or organization shares out money, assets, or benefits evenly among all eligible people based on their size or share. For example, if a company makes a profit and distributes it to shareholders, each person gets a portion proportional to how many shares they own. It ensures everyone gets their fair part based on their ownership or stake.

beneficial ownership financial

"may be deemed to share beneficial ownership of the securities held by NorthView Sponsor I LLC."

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

"disclaims beneficial ownership of such securities except to the extent of his pecuniary interest therein."

indirect ownership financial

"Common Stock transaction reported as indirectly held By NorthView Sponsor I LLC."
