US nuclear company Fermi has said recent departures from its management team were part of “a comprehensive progression” of its strategic direction, governance structure and operating platform as it continues to progress with an ambitious nuclear buildout programme.

Toby Neugebauer, the company’s co-founder and chief executive officer, suddenly departed the company this week along with chief financial officer Miles Everson

The company said Neugebauer has stepped down as chairman, although he still remains on the board.

Lead independent board director Marius Haas has stepped into the role of chairman, the company said. Everson has been elected as a board director as a result of the exercise of designation rights held by the Melissa A. Neugebauer 2020 Trust.
