Restricted Stock Award financial

"The Reporting Person acquired these shares pursuant to a Restricted Stock Award under the AtriCure, Inc. 2023 Stock Incentive Plan."

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.
