UnitedHealth Group Chairman and CEO Stephen Hemsley faces a major test Tuesday as the company reports earnings amid a sharp stock decline, DOJ investigations, and leadership turmoil.

The insurer’s shares have nearly halved since May due to plunging profits in Medicare and Optum Health, prompting the return of Hemsley after CEO Andrew Witty’s resignation.

Investors are eager to hear how he plans to restore confidence and navigate what analysts call a “perfect storm,” CNBC has reported.
