Restricted Stock Unit financial
"On October 8, 2025, the reporting person was granted 482,589 restricted stock units."
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
Stock Option (Right to Buy financial
"Stock Option (Right to Buy) with underlying common stock and specified exercise prices."
Long Term Incentive Plan financial
"On September 24, 2025, the reporting person was granted 320,000 stock options of the Company pursuant to the Company's Long Term Incentive Plan."
A long term incentive plan is a company program that awards executives and key employees bonuses—often in stock, options, or cash—only if the business meets multi-year performance goals. It links management pay to company results—like tying a coach’s bonus to a team’s multi-season record—so investors monitor it for how leaders are motivated, potential share dilution, and signals about the company’s long-term priorities.
beneficial ownership financial
"The reporting person disclaims beneficial ownership of such stock options except to the extent of his pecuniary interest therein."
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
"The reporting person disclaims beneficial ownership of such stock options except to the extent of his pecuniary interest therein."
