The filing shows an acquisition of 639 dividend equivalent rights on common stock at a price of $0.00 per share, increasing his directly held common shares to 234,294.1.

Insights

Equity compensation analyst

Routine dividend-linked RSU accrual; no open‑market buying or selling.

The filing reflects a grant-type acquisition of 639 dividend equivalent rights tied to existing restricted stock units, at a stated price of $0.00 per share. This is a standard equity compensation mechanism triggered by Iridium’s quarterly dividend of $0.15 per share.

No open-market purchases or sales occurred, and there are no derivative option exercises. The director’s direct holdings rise modestly to 234,294.1 common shares, while 36,682 additional shares are held indirectly in a grantor retained annuity trust. Overall, this looks like routine, low-signal housekeeping of stock-based awards.

restricted stock units financial

"restricted stock units with respect to the Issuer's common stock ("Original RSUs") held by the reporting person"

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.

dividend equivalent right financial

"Each dividend equivalent right entitles the reporting person to receive one share of the Issuer's common stock"

Rule 16b-3 regulatory

"The grant of dividend equivalent rights was approved by the Issuer's board of directors pursuant to Rule 16b-3"

Rule 16b-3 is a Securities and Exchange Commission regulation that exempts certain routine, pre-approved transactions by company insiders from automatic liability for short-term trading profits. It acts like a safe harbor: if an insider follows a formal plan or the board approves specific transactions in advance, profits from buying and selling company stock within six months are not automatically reclaimed. Investors care because the rule clarifies when insider trades are permissible and reduces uncertainty about potential clawbacks.
