Long Term Incentive Plan financial

"granted under the Issuer's 2024 Long Term Incentive Plan and is exercisable"

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.

Stock Option (Right to Buy) financial

"security_title: "Stock Option (Right to Buy)""

401(k) Plan financial

"nature_of_ownership: "401(k) Plan""

A 401(k) plan is a workplace retirement account that lets employees set aside part of their pay into a tax-advantaged savings pot, often with employers adding matching contributions — like a workplace piggy bank for future income. It matters to investors because the amount people save and how employers fund these plans influence consumer spending, corporate payroll costs and the flow of money into financial markets, which can affect stock prices and company valuations.
