beneficial ownership financial

"Amount beneficially owned: Keystone Cranberry, LLC - 5,842,700 Charles E. Young - 7,357,733"

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.

dispositive power financial

"Sole Dispositive Power 7,357,733.00 8 | Shared Dispositive Power 0.00"

Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.

restricted shares financial

"Also includes (i) 1,184,664 shares held directly ... and (ii) 330,369 restricted shares issued"

Restricted shares are company stock that cannot be sold or transferred immediately because they are subject to legal or contractual limits, such as a required holding period or performance conditions. They matter to investors because these locked-up shares can affect a company’s available stock for trading, future dilution, and insider incentives—imagine a gift that can’t be cashed until certain conditions are met, which changes when and how much supply can suddenly enter the market.

performance-based vesting requirements financial

"Does not include 500,879 restricted shares ... subject to performance-based vesting requirements."

Omnibus Incentive Plan financial

"restricted shares issued under the Issuer's 2016 Ombnibus Incentive Plan ("2016 Plan")"

An omnibus incentive plan is a single, flexible program a company uses to give employees and executives different types of pay tied to performance — for example stock options, restricted shares, cash bonuses and other awards — all governed by one set of rules. It matters to investors because it determines how many new shares may be created, how leaders are motivated and how much the company will spend on compensation over time; think of it as a master toolbox that affects both costs and the total share supply.
