Why is Cardinal Health stock surging today?

Cardinal Health's stock surged 3.3% in pre-market trading after the company reported impressive fiscal fourth-quarter 2026 results, significantly surpassing Wall Street expectations. The company's non-GAAP diluted EPS of $2.91 exceeded the consensus estimate of $2.42, marking a 40% increase from the previous year. Additionally, GAAP operating earnings climbed 70% to $729 million, and quarterly revenue reached $63.7 billion, up 6% year-over-year.

The earnings beat was further bolstered by various shareholder-friendly announcements, including a new $5.0 billion share repurchase authorization and a quarterly dividend of $0.5158 per share. With the broader U.S. equity market showing a neutral-to-supportive trend, the combination of these factors led to renewed investor confidence in Cardinal Health's growth trajectory and margin expansion, propelling the stock into fresh all-time high territory.
