Were the recent SMSI insider transactions open-market sales?

How many SMSI shares does William W. Smith Jr. own directly after these transactions?

The 43,366 Smith Micro shares were withheld at an average vesting price of $0.523 per share to pay income taxes due on vesting restricted stock. This tax-withholding disposition settled the tax obligation without a separate cash payment by the reporting person.

What does the forfeiture of 12,626 SMSI shares on March 4 represent?

The 12,626 Smith Micro shares forfeited on March 4 represent restricted stock returned to the issuer under the original grant terms. Such forfeitures usually occur when vesting conditions are not met or specified events occur, and do not involve cash proceeds from a market sale.

What is the role of the Smith Living Trust in SMSI share ownership?

An indirect ownership line shows 5,517,674 Smith Micro shares held through the Smith Living Trust as of February 27. This indicates a large block is owned indirectly via the trust, separate from William W. Smith Jr.’s directly held 301,669 shares following the reported dispositions.
