Restricted Stock Units financial
"Each restricted stock unit represents a contingent right to receive one share"
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.
derivative security financial
"transaction_code_description" : "Exercise or conversion of derivative security"
A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.

What type of securities did the HLIT CEO exercise in this Form 4 filing?

The CEO exercised Restricted Stock Units (RSUs), which are derivative securities. Each restricted stock unit represents a contingent right to receive one share of Harmonic (HLIT) common stock upon vesting and settlement conditions being satisfied.

Were the exercised HLIT Restricted Stock Units subject to a cash exercise price?

No, the exercised Restricted Stock Units converted into 26,196 common shares at an exercise price of $0.00 per share. This reflects a typical equity-settled RSU structure, where units settle in shares rather than requiring a cash payment.

Does the HLIT Form 4 indicate trades under a Rule 10b5-1 trading plan?

The Form 4’s Rule 10b5-1 checkbox is not checked, and no footnote describes a 10b5-1 plan. The filing therefore does not state that these RSU exercises occurred pursuant to a pre-arranged Rule 10b5-1 trading plan.
