restricted stock units financial

"These shares were withheld by the Issuer upon the vesting of restricted stock units to satisfy the Reporting Person's tax withholding obligations."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

tax withholding obligations financial

"upon the vesting of restricted stock units to satisfy the Reporting Person's tax withholding obligations."

Section 16 regulatory

"Such withholding is treated as a disposition of securities under Section 16 of the Securities Exchange Act of 1934, as amended."

Section 16 is a U.S. securities law rule that governs the trading and disclosure obligations of company insiders — typically officers, directors and large shareholders — to promote transparency and deter unfair profit-taking. It requires insiders to publicly report their stock trades and allows companies or the issuer to reclaim quick, short-term profits from certain insider trades, like a scoreboard and a refund policy that help investors see and limit possible insider advantage.

Common Stock financial

"security_title": "Common Stock""

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.

No. The Form 4 states the dispositions were tax-withholding events tied to restricted stock unit vesting. Shares were withheld by OptimizeRx to satisfy Greco’s tax obligations, so these are not open-market sales and do not represent discretionary selling activity.
