The battle between Riot and Bitfarms

Riot announced a $950 million acquisition bid for Bitfarms in late May, claiming that Bitfarms’ founders were not acting in the best interests of all shareholders. They stated that their proposal was rejected by the Bitfarms board without substantive engagement.

Bitfarms responded by stating that Riot’s offer “significantly undervalues” its growth prospects. 

Bitfarms then implemented a shareholder rights plan, often called a “poison pill,” to protect its strategic review process from hostile takeover attempts by Riot Platforms.

Riot owned 11.62% of Bitfarms’ shares at the time of the acquisition bid, Bitfarms’ board unanimously supported the poison pill plan to ensure their shareholders’ interests are safeguarded.
