Johnson & Johnson shares rise as $3.5B biotech deals expand oncology pipeline
Johnson & Johnson (JNJ) shares rose 0.86% to $258.03 after announcing two biotech deals totaling $3.5B. The company acquired Firefly Bio for $1B and partnered with Sail Biomedicines, with an option to buy it for $2.58B. These deals aim to expand JNJ's oncology and immunology pipelines but will reduce EPS in 2026-2027.
