Boston Scientific Corporation (NYSE: BSX) today announced it has entered into a definitive agreement to acquire Nalu Medical, Inc., a privately held medical technology company focused on developing and commercializing innovative and minimally invasive solutions for patients with chronic pain.
Boston Scientific has been a strategic investor in Nalu Medical since 2017. The transaction consists of an upfront cash payment of approximately $533 million for the remaining equity not owned by Boston Scientific.*
The Nalu Neurostimulation System is designed to deliver targeted relief for adults living with severe, intractable chronic pain of peripheral nerve origin, including areas such as the shoulder, lower back and knee, through peripheral nerve stimulation (PNS). The therapy uses mild electrical impulses to interrupt pain signals before they reach the brain. The system features a miniaturized, battery-free implantable pulse generator, powered wirelessly by a small, externally worn therapy disc and controlled via a smartphone app.
Nalu Medical received U.S. Food and Drug Administration 510(k) clearance for the Nalu system in 2019. In the COMFORT and COMFORT 2 randomized controlled trials, evaluating the safety and efficacy of PNS, the system demonstrated significant and sustained pain relief for patients. In COMFORT, 87% of participants reported more than a 50% reduction in pain at 12 months,i while in COMFORT 2, 79% of patients reached an average pain relief of 64% at six months.ii Real-world data from more than 2,000 individuals reinforced these findings, with 94% of patients achieving clinically meaningful improvement across a broad range of chronic peripheral nerve pain conditions.iii
“Peripheral nerve stimulation is an exciting field with a significant unmet patient need,” said Jim Cassidy, president, Neuromodulation, Boston Scientific. “Adding the highly differentiated Nalu Medical technology complements our existing therapies—including spinal cord stimulation, basivertebral nerve ablation and radiofrequency ablation—enabling us to deliver advanced pain relief options to a wider variety of patient populations.”
Boston Scientific expects to complete the transaction in the first half of 2026, subject to customary closing conditions. Nalu is expected to generate sales in excess of $60 million in 2025 and to deliver year-over-year growth in excess of 25% in 2026. On an adjusted basis, the transaction is expected to be immaterial to adjusted earnings per share (EPS) in 2026, slightly accretive in 2027, and increasingly accretive thereafter. On a GAAP basis, the transaction is expected to be more dilutive due to amortization expense and acquisition-related charges.
*On a 100% basis before consideration of Boston Scientific’s current equity ownership in Nalu Medical, Inc. and other closing adjustments, the transaction price consists of an upfront cash payment of $600 million.
