Effective October 29, 2021, as part of an internal realignment of roles and duties stemming from CleanSpark, Inc.'s focus on its non-energy segments' significant growth, Amanda Kabak, the Chief Technology Officer, stepped down from her role as Chief Technology Officer. Ms. Kabak will continue to work for the Company in the role of VP of Software Architecture. The Company does not currently expect to replace the role of Chief Technology Officer at the corporate level, as all software development efforts will occur at the subsidiary level under the direction of the President of the Energy Division.
