4 terms

Restricted Stock Unit financial

"Each Restricted Stock Unit (RSU) represents a contingent right to receive one share of Momentus Inc. Class A 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.

Form 4 regulatory

"This first amendment to the Form 4 filed by the Reporting Person on 05/21/2026 indicates a correction to the amount of securities acquired."

Form 4 is a official document that company insiders, such as executives or major shareholders, file with regulators whenever they buy or sell company shares. It provides transparency about how those with inside knowledge are trading, helping investors see if insiders are confident in the company's prospects or may be selling for personal reasons. This information can influence investor decisions by revealing insiders' perspectives on the company's value.

derivative securities financial

"This first amendment to the Form 4 filed by the Reporting Person on 05/21/2026 indicates a correction to the amount of derivative securities acquired."

Financial contracts whose value is tied to the price or performance of another asset, such as a stock, bond, commodity, index, or currency; examples include options, futures and swaps. They matter to investors because they let you protect against price swings, bet on future moves or gain larger exposure with less upfront cash—like using a lever or insurance policy on an investment—so they can amplify gains and losses and help manage portfolio risk.

vesting financial

"Represents a grant of RSUs, which vest in three equal annual installments from Vesting Commencement Date, subject to Executive's continued Employment through each such vesting date."

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
