The historical performance data from Biglari's other investments, particularly Steak 'n Shake and Western Sizzlin', reveals a concerning pattern. At Steak 'n Shake, system sales declined 9.0% annually, with revenue dropping 20.6% annually. Western Sizzlin' saw a dramatic unit reduction from 140 to 33 locations. These outcomes suggest potential risks to CBRL's long-term viability under Biglari's influence.
