tax-withholding disposition financial
"Payment of exercise price or tax liability by delivering securities"
A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.
Long Term Incentive Plan financial
"earned under the 2024-2026 Long Term Incentive Plan granted on 5/23/2024"
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.
Performance Restricted Stock Units financial
"Includes 19,316 Performance Restricted Stock Units earned under the 2024-2026 Long Term Incentive Plan"
Performance restricted stock units (PRSUs) are promises to deliver company shares to employees or executives only if the business meets specific performance targets and any time-based holding rules. Think of them as a bonus that converts into stock only after set goals are reached, so investors watch PRSUs for two reasons: they can dilute existing shares if paid out, and they signal how closely management’s pay is tied to company performance.
401(k) Plan financial
"L.B. Foster Company 401(k) Plan Shares"
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.
