restricted stock award financial

"Shares withheld on vesting of restricted stock award to cover tax withholding."

A restricted stock award is company shares given to an employee or executive that cannot be sold or fully owned until certain conditions—like staying with the company for a set time or hitting performance targets—are met. Think of it as a gift that only becomes yours after you fulfill specific obligations; for investors, these awards matter because they can increase the total shares outstanding when they vest, reveal how management is being paid and motivated, and create potential selling pressure when restrictions lift.

tax withholding financial

"Shares withheld on vesting of restricted stock award to cover tax withholding."

Tax withholding is the practice of taking a portion of a payment—such as wages, dividends, or sale proceeds—before it reaches the recipient and sending that portion to the tax authority as an advance on the recipient’s eventual tax bill. For investors it matters because withholding reduces immediate cash received and affects after‑tax returns, estimated tax payments, and whether you may owe more or receive a refund when taxes are finally calculated, like having a small automatic savings set aside for your tax bill.

Form 4/A regulatory

"The reporting person's original Form 4 filed on April 2, 2026 mistakenly reported a per-share market value..."

Form 4/A is an amended filing that corrects or updates an earlier Form 4, the mandatory report that insiders (like company executives, directors, or large shareholders) must file when their ownership stakes change. Think of it as an edited receipt showing who bought or sold stock and when; investors use it to track insider confidence, detect potential conflicts, and spot trading patterns that might signal future company prospects.

market closing price financial

"the market closing price on April 1, 2026 was $36.71."
