Reitman Maureen T. F. 4

What Happened

• Maureen Reitman, Group Vice President of Exponent (EXPO), had 5,510 vested restricted stock units (RSUs) convert into common shares on 2026-03-11. The company withheld 1,756 of those shares to satisfy tax withholding obligations at $70.03 per share (value reported: $122,973), leaving a net 3,754 shares delivered to Reitman.
• This was a routine conversion of compensation (RSU vesting), not an open-market purchase or voluntary sale.

Context

• This was a compensation vesting event (RSU conversion). Withholding shares to cover taxes is common and does not necessarily signal any change in the insider's market view.
• Because the RSUs converted rather than shares being bought or sold in the open market, this is routine insider compensation reporting rather than a purchase/sale investment decision.
