PULSE BIOSCIENCES (PLSE) posted its first commercial revenues of $86,000 in Q3 2025, reflecting the company's transition from pre-commercial to early market activity. Revenue was driven by limited market release sales of the NPulse Vibrance system and related disposables, targeting soft tissue ablation for benign thyroid nodules. This initial revenue base is modest, but it marks a critical inflection as the company moves from pilot to commercial accounts.
Expenses rose sharply, with GAAP costs and expenses up $6.8 million year-over-year to $20.5 million, primarily due to organizational expansion for clinical trials and commercialization, as well as non-cash stock-based compensation. Non-GAAP net loss widened to $13.5 million, reflecting the deliberate investment phase. Cash used in operations increased to $13 million, with quarter-end cash at $95.2 million, offering runway for ongoing trials and early commercialization. Management emphasized that most procedures are still under pilot or study protocols and not yet contributing to revenue, underscoring the long-term focus on clinical validation and market development.
- Commercialization Progress: Initial sales and procedure growth highlight early acceptance among targeted providers.
- Expense Ramp Tied to Clinical Expansion: Headcount and R&D spending rose to support pivotal studies and market entry.
- Cash Position Remains Solid: $95.2 million in cash provides a buffer for continued clinical and commercial investments.
PULSE’s Q3 results reflect a company in the early innings of market entry, balancing investment in clinical validation with disciplined commercial rollout.
Executive Commentary
"We are driving early targeted adoption of the MPulse Vibrance percutaneous electrode system for soft tissue ablation with benign thyroid nodule treatment as the first use case... We are intensely focused during this early phase, ensuring we identify proper patients, develop and train physicians and staff on consistent techniques across multiple conditions, confirm market access for commercial reimbursement, and provide clinical support to generate consistently positive outcomes."
