My opinion on why NP was fired is pretty cut and dry . He made a pivot in the strategy of the company and threw the company’s energy , scarce cash, and focus behind Covid . This expensive shift was an all or nothing that CEOs do sometimes. Taking a risk and going all in. Once CD12 failed he continued by pumping energy and cash into chasing the virus globally, always one step behind the virus through the Philippines, Brazil and other locations. By the end of 2021 it was obvious to the new Board Chairperson that the shift failed as total revenue for this effort was a mere $425k. Add to that the DOJ overhang and the Board felt the company was going in the wrong direction . All speculation on my part but the timing coinciding with a new Board Chief just two months before , along with the obvious poor results of the spend , in my mind, led to NPs demise. Cyrus coming on board 6 months later as a more seasoned Pharma professional with the directive to clean house and put together a more focused strategy while at the same time , navigating the company through the difficult financial situation is probably what the reasoning was for him coming on board. Again, my speculation but looking at the timing of things and events, leads me to believe these things.
