Restricted Stock Units financial

"Each restricted stock unit ("RSU") represents the 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.

cliff vest financial

"The Award will cliff vest on the one-year anniversary of the Grant Date"

A cliff vest is a schedule for stock options or restricted shares where no ownership rights are earned until a fixed date, after which a set portion becomes fully owned all at once — like a probation period that suddenly unlocks pay. Investors watch cliff vests because they influence when insiders can sell shares, affect staff retention and dilution timing, and help predict short-term changes in a company’s shareholder makeup.

Equity Incentive Plan financial

"granted pursuant to the TETRA Technologies, Inc. Third Amended and Restated 2018 Equity Incentive Plan"

An equity incentive plan is a program that gives employees, executives or directors the right to receive company stock or options to buy stock as part of their pay. Think of it as offering slices of future company profit to motivate people to boost long‑term performance; for investors it matters because it can align employee goals with shareholder value but also increases the number of shares outstanding, which can dilute existing ownership.

settlement date financial

"Vested shares will be delivered to the reporting person on the settlement date"

The settlement date is the day when a securities trade is finalized: the buyer’s cash is delivered and the seller’s shares or bonds are transferred into the buyer’s account. Think of it like the closing day of a purchase, when ownership and payment officially change hands; until then the trade exists as an agreement but not as completed property transfer. Investors care because payment timing affects cash availability, record of ownership, dividends, and legal rights tied to the asset.

contingent right financial

"represents the contingent right to receive one share of Issuer's common stock"
