beneficially own financial
"may be deemed to beneficially own the NEA 17 Shares"
Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.
pro rata distribution financial
"NEA 17 made a pro rata distribution of 1,000,000 shares"
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.
sole voting power financial
"Number of Shares Beneficially Owned by Each Reporting Person With: | 7 | Sole Voting Power"
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 6,692,298.00"
percent of class financial
"13Percent of class represented by amount in Row (11) 7.9 %"
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.
options to purchase financial
"record owner of options to purchase 135,432 shares of Common Stock"
A legal right, usually in the form of a contract, that lets someone buy a specific asset—most often shares—at a set price within a fixed time period. Think of it like a reservation or coupon that guarantees today’s price for a future purchase; investors watch these because exercising the options can change how many shares exist, affect company ownership, and create potential gains or dilution for existing shareholders.
