Boston Scientific Corporation secured net sales of $5.203 billion during the first quarter of 2026, growing 11.6% overall. The company’s guidance predicted 10.5% to 12% growth for the period.
In addition, the company’s MedSurg segment posted 7.8% growth, while its cardiovascular segment posted 13.5% growth.
Amid growing competition in the cardiovascular space, and a
recent shareholder lawsuit over inflated Electrophysiology
results, this growth is a good sign for both the company and its investors.
Despite the growing competition, Boston Scientific has managed to
retain its place on the list of the top nine cardiovascular device companies
in the world in 2026.
The global cardiovascular devices market size was valued at $53.67 billion in 2024 and is anticipated to grow at a CAGR of 8.4% from 2025 to 2030.
WATCHMAN FLX, EKOS, and FARAPULSE studies demonstrate clinical superiority
During Q1 2026, the company also made several strides in its cardiology portfolio. Research presented at the American College of Cardiology’s annual meeting
demonstrated that the WATCHMAN FLX Left Atrial Appendage Closure Device
as a first-line option for stroke risk reduction met all primary and secondary endpoints and demonstrated superior bleeding risk reduction and similar efficacy of the WATCHMAN FLX device compared to oral anticoagulants in a broad population of patients with non-valvular atrial fibrillation.
A second study demonstrated that the EKOS Endovascular System for the treatment of acute pulmonary embolism (PE) in patients with intermediate-risk PE demonstrated the EKOS system plus anticoagulation was superior to anticoagulation alone.
The company also announced positive outcomes from the ADVENT Long-Term Outcomes clinical trial, which demonstrated greater long-term AF treatment success, fewer hospital-based arrhythmia interventions and lower repeat ablation rates at four years with
FARAPULSE Pulsed Field Ablation (PFA) compared to thermal ablation
, received National Medical Products Association approval in China for the OPAL HDx Mapping System, which enables catheter visualization during FARAPULSE PFA procedures, and determined that patients found statistically significant pain relief and improved quality of life with peripheral nerve stimulation therapy with the Nalu Neurostimulation System compared to conventional medical management in patients with chronic pain.
Boston Scientific completes Valencia technologies acquisition, advances Penumbra deal
This quarter, Boston Scientific also
completed the acquisition of Valencia Technologies Corporation
, a privately held company focused on the development and commercialization of the eCoin System, an implantable tibial nerve stimulation device for the treatment of urge urinary incontinence.
In the same quarter, Boston Scientific also
announced plans to acquire Penumbra
, and
officially acquired Nalu
.
The company now estimates net sales growth for the full year 2026, versus the prior year period, to be approximately 7% to 8.5%. The company estimates net sales growth for the second quarter of 2026, versus the prior year period, to be approximately 5.5% to 7.5%.
Company lowers full-year 2026 guidance to 7-8.5% growth
This guidance is down from Boston Scientific’s original guidance of 8.5% to 10% full year growth.
The company also said its outlook excludes the impact of foreign currency fluctuations and net sales attributable to certain acquisitions and divestitures.
Analysts at BTIG still remain strong on the stock, holding a buy rating, despite adjusting the company’s price target from $90 to $110.
"Our global team and the strength of our category leadership strategy enabled us to deliver solid results this quarter," Mike Mahoney, chairman and CEO of Boston Scientific, said in a prepared release. "We remain focused on executing our long-term strategy and advancing our differentiated pipeline to drive meaningful impact for patients, physicians and hospital systems."
Following the release of Q1 2026 results, the company’s stock jumped 10%.
This is the third quarter in a row that high sales and growth for Boston Scientific have been
led by its cardiovascular segment
.
Electrophysiology segment faces headwinds from PFA competition
Investors should, however, remain leery of its Electrophysiology segment performance following the aforementioned shareholder lawsuit.
In February, Boston Scientific missed consensus for its electrophysiology segment by $33 million due to increased competition in the pulsed-field ablation market.
Marie Thibault, a BTIG analyst, wrote, “The closely watched electrophysiology segment missed consensus by $33 million, confirming investor fears.”
Because of the sales miss, BTIG analysts readjusted their forecast for the electrophysiology segment.
“We reduce our electrophysiology revenue forecast and increase our ICVT outlook,” Thibault wrote. “We now model 17% year over year worldwide sales growth for EP, reflecting estimates for 13% U.S. year-over-year EP sales growth and 25% OUS year-over-year EP sales growth.”
Thibault also wrote, “Boston Scientific has dazzled investors in the past with its one-two punch of Farapulse and Watchman, but we think that era is likely behind us.”
