So Twitter was at $70 per share a year ago. So what? Jack Dorsey was CEO a year ago, too. The share price was $33 less than a month ago. But, despite an absolutely incredible roller-coaster news cycle, things have been definitely trending down at Twitter ($33/share last month), which was reflected in its share price. The current executive team (and Dorsey) had wasted time focusing on things that didn't matter instead…
Here is what would be looking after their fiduciary duties:
The company had a loss of 200 million dollars this year. Was only profitable 2 years out of its 16 years of existence. The board should state that Twitter in the hands of Elon Musk, could jeopardize its current unique and somewhat also precarious, place in social media.
The company should ask Elon Musk, to first explain to shareholders what he plans to do with the company, and how it would benefit them. Provide details on shape and form of how his plan would be implemented. Until then, rejecting the offer is looking after their fiduciary duties.
