HCA continued its steady performance under Johnson's leadership. He has served as CEO since 2014. While other hospital systems tweak their business strategies, HCA has stayed true to its core operations. That commitment has paid off. The for-profit chain's net income jumped 25% during the second quarter of 2018, beating key earnings predictions from Wall Street analysts. The strong quarter prompted HCA to raise its internal performance guidance for fiscal 2018, increasing its revenue prediction by $500 million to between $45.5 billion and $46.5 billion.
