Carrols Restaurant Group Altman Z-Score, Current: 2.18Altman Z-Score, 2009: 2.3Carrols Restaurant Group's ( TAST) Z-Score declined to 2.18 in the trailing 12 months. Its score keeps the operator of Pollo Tropical and Taco Cabana restaurants in the grey area, and not necessarily headed for bankruptcy anytime soon, but its declining rating, from 2.3 in 2009, does not bode well. To boot, Carrols is also a franchisee of Burger King restaurants, also on TheStreet's list of risky restaurant stock plays. In its recent quarter, comps increased 6.3% at Pollo Tropical, decreased 0.1% at Taco Cabana and decreased 1.4% at its Burger King locations. Revenue edged up 0.3% to $204.5 million in the period, but Carrols' net profits plummeted 66.2% to $2.4 million, or 11 cents per share. Carrols expects comps at Pollo Tropical to grow as much as 5% this year while same-store sale at Taco Cabana locations are likely to be flat. Its Burger King comps are expected to be negative for the year.
