Rule 10b5-1 trading plan regulatory

"The sales reported in this Form 4 were effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person."

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

withholding taxes financial

"Represents shares sold in payment of withholding taxes upon partial vesting of RSUs pursuant to a Rule 10b5-1 trading plan adopted by the reporting person."

Withholding taxes are amounts a payer or government takes out of payments — such as wages, interest, or dividends — before the recipient gets the money, functioning like a cashier keeping part of a bill to pay taxes on your behalf. For investors this matters because it reduces the cash they actually receive, affects net returns and yield calculations, and may require additional paperwork or treaty claims to recover or offset the withheld amount against final tax bills.

restricted stock units (RSUs) financial

"Includes the following pursuant to the 2018 Coastal Financial Corporation Omnibus Incentive Plan: (1) 12,791 restricted stock units (RSUs) with remaining shares vesting monthly..."

Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

performance-based RSUs financial

"15,000 performance-based RSUs - eligible to vest on April 30, 2028, subject to continuous employment and achievement of return on equity criteria."

Performance-based restricted stock units (RSUs) are promises to deliver company shares to employees only if the business meets specific goals, such as revenue, profit, stock-price targets, or strategic milestones. For investors, they matter because they change future share supply and align management incentives with company results—like a salesperson whose bonus only pays out when sales targets are hit—so they can affect earnings, dilution, and confidence in leadership.

Omnibus Incentive Plan financial

"Includes the following pursuant to the 2018 Coastal Financial Corporation Omnibus Incentive 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.
