Restricted Stock Unit financial
"Each restricted stock unit represents a contingent right to receive one share of common stock."
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
tax withholding obligations financial
"withholding of shares by the issuer to satisfy the reporting person's tax withholding obligations"

"The stock option grant was approved by Inovio's Board of Directors on March 4, 2026"
Omnibus Incentive Plan financial
"under which the stock options were granted. Inovio's shareholders approved the amendment and restatement of the Amended and Restated 2023 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.
