Johnson & Johnson Shares Rise 089% in Second Consecutive Day of Gains Trading Volume Ranks 78th in Market

Johnson & Johnson (JNJ) shares rose 0.89% on June 6, 2025, marking the second consecutive day of gains, with a total increase of 1.18% over the past two days. The trading volume for the day was 8.35 billion, ranking 78th in the overall market.

Johnson & Johnson has been ordered to pay $442 million in damages in an antitrust case involving the reprocessing of cardiac mapping catheters. This decision comes after a federal jury in Central California awarded Innovative Health $147 million in damages last month. The jury found that J&J's Biosense Webster business had violated sections of the federal Sherman Antitrust Act and California’s Cartwright Act through tying and other anticompetitive practices, allegedly maintaining a monopoly on cardiac mapping catheters and squeezing out reprocessors such as Innovative Health.

Daniel J. Vukelich, president and CEO of the Association of Medical Device Reprocessors (AMDR), described the ruling as a "seismic result," emphasizing that the court's decision to triple the damages sends a clear message to all device manufacturers that anti-competitive tactics will not be tolerated. The lawsuit, which dates back to 2019, accused J&J of illegally tying access to its Carto 3 cardiac mapping system specialists with the purchase of brand-new catheters, thereby maintaining a monopoly on the market.
