Nieuwoudt joined the board effective November 4, with appointments to its Audit and Compensation & Leadership Development committees. Aspen expanded the board from six directors to seven.

  • Board term and experience: Nieuwoudt will serve as a Class III director through the company’s 2029 annual meeting. She has been a private investor since 2019 and previously worked as an energy and industrials analyst at Citadel affiliates.

She also received a prorated award of restricted stock and stock options. The award is scheduled to vest before the 2027 annual meeting or upon a change in control, whichever comes first.
