What this transaction means for investors

Iridium CEO Matthew Desch's Sept. 1 sale of company stock does not represent a red flag for investors, since it was a non-discretionary transaction executed to fulfill tax withholding obligations in connection with the vesting of restricted stock units (RSUs).

An RSU is a form of compensation where a company grants an employee shares of stock at a future date. When that vesting date arrives, as was the case here, a "sell to cover" transaction occurs to pay the related taxes.

Iridium Communications stock soared 88% over the trailing 12 months through Sept. 1 thanks to its impending acquisition by Rocket Lab. The deal involves a combination of cash and stock, and values Iridium at $54 per share.

The transaction is set to close in mid-2027, although it must get past regulatory hurdles, and the deal involves a collar. These factors have weighed on Iridium stock, and shareholders are likely to lose the dividend payments they've enjoyed to date. Rocket Lab does not currently pay a dividend and is not a profitable company.
