Anyone following the recent financial statements of the company can realize, like this group has, that something needs to change. Either Oil has to go back over $60-$70 per barrel and/or the company must invest into other sources/industries for future sales/income and its own survival.
Unfortunately for this Engine group, they only own 0.2% of the shares of the company. So, as much as they might want it, there is no way they are going to be able to do anything on their own.
While this currently garners some headlines, I'm sure every one has seen past shareholder initiated proxy proposals, none of which have passed throughout the decades.
It will take strong engagement by many many others (shareholders) to gather a significant majority before management will have to pay any attention to this at all.
