restricted stock units ("RSUs") financial

"Received in exchange for 500,000 unvested restricted stock units ("RSUs") of First Foundation Inc."

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

exchange ratio financial

"based on the exchange ratio in the merger of 0.16083 of a share of FirstSun common stock"

The exchange ratio is the number used to decide how many shares of one company you get for each share you own in another company during a merger or acquisition. It’s like a recipe that tells you how to swap shares fairly, ensuring both companies’ values are balanced. This ratio matters because it determines how ownership divides between the companies' shareholders.

revocable living trust financial

"Thomas C. Shafer Revocable Living Trust"

merger financial

"in connection with the merger of First Foundation with and into FirstSun"

A merger is when two companies combine into a single business, with ownership and control reorganized so they operate as one entity. For investors it matters because mergers can change the value and risk of holdings—shares may be exchanged, diluted, or rise if the combined company saves costs or gains market power, and the deal often depends on regulatory approval and successful integration like two households joining resources and routines.
