Fill up on gas: The Tipline for 4 August 2020

7-Eleven is best known for its Big Gulp soft drinks and hot dogs, but it expanded its business significantly yesterday by agreeing to purchase rival Speedway. The deal follows the gas station and convenience store chain's smaller purchase of gas stations in 2017, which the Federal Trade Commission approved with divestitures. Also in today’s Tipline, the FTC reportedly joins with New York and California to probe Amazon, health insurance purchasers suing California health insurer Sutter Health score class certification and a cancer treatment deal sets Siemens Healthineers on track to become a global leader in cancer care.
