Cardinal Health has launched a drone delivery service in North Carolina, partnering with Novant Health and Magellan Rx Management to enhance product distribution. Despite this innovative step, the company faces significant financial difficulties, having reported losses last year while paying dividends that exceed its free cash flow. Analysts have downgraded their earnings estimates for Cardinal Health, questioning its viability as a long-term dividend investment, especially given a 19% annual decline in earnings per share over five years.
