After Pressure, All-Male Boards Have Now Vanished From S&P 500

  • Monolithic Power added a female director in May after search
  • Men retiring helped women rise to 29.7% of board seats

Monolithic Power Sytems Inc. added a female director last month, ending the power-management company’s three-month run as the only S&P 500 member with an all-male board.

The appointment of Carintia Martinez, chief information officer at European aerospace company Thales Alenia Space SAS, caps a year-long search for a company that hadn’t had a woman on the board since 2016.
