On August 14, 2025, Cardinal Health (CAH) rose 1.42% with a trading volume of $420 million, ranking 243rd in market activity.

Despite short-term volatility, the company’s updated earnings guidance signals confidence in its strategic direction. The deal underscores Cardinal’s focus on high-margin, high-growth specialties to diversify its revenue streams.
