Johnson & Johnson Shares Dip After Closing $3.05bn Halda Therapeutics Acquisition

Johnson & Johnson shares slipped around 0.3% in after-hours trading after the company confirmed it had completed its $3.05 billion all-cash acquisition of oncology-focused biotech Halda Therapeutics. The deal adds Halda’s RIPTAC platform and lead prostate cancer asset HLD-0915 to J&J’s oncology pipeline, while prompting investor focus on near-term earnings impact and future growth potential.

Oncology Pipeline Expansion with Near-Term EPS Impact
The acquisition strengthens J&J’s Innovative Medicine portfolio with Regulated Induced Proximity Targeting Chimera (RIPTAC) technology, designed to enable more precise, oral targeted cancer therapies. However, the company expects approximately $0.20 of dilution to adjusted earnings per share, split evenly across 2025 and 2026, reflecting increased pipeline investment ahead of clinical and commercial milestones.

Investor Focus Shifts to 2026 Outlook
With the transaction completed, attention is turning to Johnson & Johnson’s January 21 earnings call, where management is expected to outline full-year 2026 guidance. Investors will closely watch integration costs, clinical progress of HLD-0915, and whether the Halda platform can translate long-term scientific promise into sustainable earnings growth.
