Context These are routine tax-withholding transactions that occur when restricted stock units vest; the company or insider surrenders shares to cover withholding rather than selling in the open market. Such forfeitures do not necessarily signal insider sentiment about the company’s stock — they are administrative actions tied to compensation vesting.
