Restricted Stock Units (RSUs) financial

"Certain of these securities are RSUs. Each RSU represents a contingent right to receive one share of Class A Common Stock"

Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

statutory tax withholding obligations financial

"shares sold to cover the statutory tax withholding obligations in connection with the vesting of Restricted Stock Units (RSUs)"

weighted-average price financial

"The "Amount" and "Price" reported in this Column 4 reflect the aggregate number and weighted-average price"

Equity Incentive Plan financial

"The options are granted pursuant to the BlackSky Technology Inc. 2021 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.

vesting schedule financial

"One third (1/3rd) of the award vests on March 10, 2026, and thereafter, one thirty-sixth (1/36th) of the award vests"

A vesting schedule is a timeline that determines when someone gains full ownership of certain benefits, such as company stock or retirement contributions. Think of it like earning the right to own a gift gradually over time, rather than receiving it all at once. It matters to investors because it affects when they can fully access or sell these benefits, influencing their financial planning and decision-making.
