Acquisition provides highly differentiated clinical-stage treatment for prostate cancer, building on Johnson & Johnson’s nearly two decades of innovation in the disease area

Lead asset shows potential to overcome common types of resistance to treatment in prostate cancer with a precision tumor cell-killing approach

Includes novel technology platform capable of developing the next generation of highly targeted oral treatments for multiple solid tumors, including breast and lung cancers

Johnson & Johnson (NYSE: JNJ) announced today that it has entered into a definitive agreement to acquire Halda Therapeutics OpCo, Inc. (Halda), a clinical-stage biotechnology company with a proprietary Regulated Induced Proximity TArgeting Chimera (RIPTAC™) platform to develop oral, targeted therapies for multiple types of solid tumors, including prostate cancer, for $3.05 billion in cash. The transaction is expected to close within the next few months, subject to antitrust clearance and other customary closing conditions.

The lead candidate, HLD-0915, is a clinical-stage therapy for prostate cancer, of which new diagnoses are projected to reach 1.7 million globally by 2030¹. Given the existing unmet need, this once-daily therapy has the potential to transform patient outcomes with its novel precision cancer cell-killing approach that can overcome mechanisms of resistance to treatment. The acquisition also includes several earlier candidates for breast, lung and multiple other tumor types. Halda’s pipeline and platform may also enable the creation of novel targeted therapies beyond oncology.

“This acquisition further strengthens our deep oncology pipeline with an exciting lead asset in prostate cancer and a platform capable of treating multiple cancers and diseases beyond oncology, providing a potential mid- and long-term catalyst for growth,” said Jennifer Taubert, Executive Vice President, Worldwide Chairman, Innovative Medicine, Johnson & Johnson. “We look forward to combining Halda’s pipeline, platform and people with our world class R&D, commercial and manufacturing capabilities and advancing our goal of bringing these therapies to patients around the world.”

“Many therapies lose effectiveness over time due to resistance. Halda’s innovative technology is designed to work even when cancers no longer respond to standard treatments using a novel mechanism that enables the selective killing of cancer cells,” said John C. Reed, M.D., Ph.D., Executive Vice President, Innovative Medicine, R&D, Johnson & Johnson. “Results seen with HLD-0915 demonstrate impressive preliminary efficacy and a strong early safety profile in prostate cancer. We are eager to accelerate the ongoing Phase 1/2 clinical trial of HLD-0915 and progress a pipeline of novel product candidates based on RIPTAC™ technology​.”

The planned acquisition underscores Johnson & Johnson’s longstanding commitment to prostate cancer and industry-leading oncology portfolio, adding new therapies with novel and complementary mechanisms of action. Halda’s pipeline of differentiated assets, if successful, will provide critical new options for patients.

About the Acquisition Agreement

Under the terms of the agreement, Johnson & Johnson will acquire Halda. The transaction will be accounted for as a business combination and is expected to close within the next few months, subject to antitrust clearance and other customary closing conditions. The Company expects dilution in 2026 of $0.15 to Adjusted Earnings Per Share (EPS) due to short-term financing and a non-recurring charge related to the equity awards for Halda employees upon closing.
