restricted stock unit financial
"Each share is represented by a restricted stock unit (RSU) that represents a contingent right"
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.
RSU Award financial
"The RSU Award was granted on May 28, 2026 and 100% of the RSU Award will vest"
contingent right financial
"represents a contingent right to receive one share of DexCom, Inc. Common Stock"
Revocable Trust financial
"Shares are held by the Richard A. Collins Revocable Trust, with respect to which"
A revocable trust is a legal arrangement where the person who creates it keeps control and can change or cancel the trust at any time, while naming who will manage and receive the assets later. Think of it like a flexible folder for your investments and property that can be relabeled or reworked as circumstances change; it matters to investors because it determines how ownership is recorded, how easily assets transfer on incapacity or death, and whether holdings bypass public probate proceedings.
