Why it's interesting
Yum Brands, which opened 174 net new units in the quarter, has been able to offset ongoing trouble at its Pizza Hut chain with the strong success of Taco Bell.
The Kentucky-based company has worked to strengthen its pizza business by funneling $130m into upgrading equipment, increasing advertising and revamping restaurant technology.
In the second quarter Yum Brands noted a $12m charge due to investments in Pizza Hut's digital initiatives.
