At the heart of the company's mission is the RNS System, a novel and differentiated brain-responsive neuromodulation system designed to deliver personalized, real-time treatment directly at the seizure source. This technology represents a significant advancement over traditional, non-responsive stimulation devices. The RNS System operates by continuously monitoring the brain's electrical activity. It is uniquely capable of recognizing patient-specific abnormal electrical patterns that precede seizures and responding instantly with imperceptible electrical pulses to prevent them. This targeted, on-demand therapy contrasts with devices that deliver continuous or scheduled stimulation, regardless of the brain's real-time state. Furthermore, the RNS System is the only commercially available device that records continuous brain activity data, providing clinicians with invaluable insights for optimizing patient care and making more informed treatment decisions, even remotely. The company believes these therapeutic advantages, coupled with the power of its extensive brain data set, offer a substantial leap forward in epilepsy treatment. NeuroPace's technological edge is not merely theoretical; it is supported by compelling clinical evidence. Data from the post-approval study in adults with focal epilepsy, presented in April 2025, demonstrated an impressive 62.5% median seizure reduction at six months post-implant, improving to 82.0% at 36 months. Critically, 42.5% of patients in the study achieved a period of seizure freedom lasting at least six months, with 22.0% remaining seizure-free for at least one year. These outcomes compare favorably to other neuromodulation therapies like VNS (Vagus Nerve Stimulation) and DBS (Deep Brain Stimulation), which have shown lower median seizure reductions (e.g., 30% for VNS and 23% for DBS at six months, 44% for VNS and 40% for DBS at three years in their respective studies) and lower rates of seizure freedom (e.g., 8% for VNS and 4% for DBS at last follow-up in their most recent studies). This quantifiable clinical superiority forms a core part of NeuroPace's competitive moat. The company is not resting on its laurels, continuing to invest in research and development to enhance the RNS platform. This includes developing AI-enabled software tools, leveraging its unique brain data, such as an AI-powered seizure classifier planned for release in the second half of 2025, designed to streamline physician workflow and provide deeper insights into patient rhythms. Development of a next-generation device platform is also underway, signaling a commitment to long-term technological leadership. These initiatives aim to improve efficiency, ease of use, and ultimately, increase the effectiveness of RNS therapy, further strengthening the company's competitive position. Within the competitive landscape, NeuroPace operates in a market with significant unmet need, targeting the approximately 1.2 million U.S. patients living with drug-resistant epilepsy. While ablative or resective surgery is an option, an estimated 80% of drug-resistant focal epilepsy patients are not suitable candidates or are unwilling to undergo such procedures. This leaves neuromodulation as a primary alternative, where NeuroPace competes directly with larger, more diversified medical device companies like Medtronic (TICKER:MDT) and LivaNova (TICKER:LIVN), which offer DBS and VNS systems, respectively. These competitors possess significantly greater resources, longer operating histories, and established relationships. However, NeuroPace's focused expertise and superior clinical data in its indicated population provide a critical differentiator. While larger competitors benefit from economies of scale and broader distribution networks, NeuroPace's specialized technology and data capabilities allow it to target a niche where its clinical performance stands out. Indirect competition comes from pharmaceutical companies offering anti-epileptic drugs, which, while often less effective for drug-resistant cases, represent a lower-cost initial treatment path. NeuroPace's strategy is to leverage its clinical superiority and expanding access initiatives to drive adoption despite the scale advantages of its rivals. ## Building Momentum: Performance and Strategic Execution NeuroPace's recent financial performance reflects the increasing traction of its core RNS System and the initial impacts of its strategic initiatives. For the first quarter of 2025, the company reported total revenue of $22.5 million, representing a robust 24% increase compared to $18.1 million in the prior-year period. This growth was primarily fueled by a 26% surge in RNS System sales, or 29% when excluding the impact of NAUTILUS study implants in Q1 2024, demonstrating strong underlying demand for the core technology. Sales of DIXI Medical SEEG products also contributed to this growth, although this contribution is set to change. Gross margin saw a notable improvement, rising to 77.0% in Q1 2025 from 73.6% in Q1 2024. This expansion was primarily attributed to enhanced manufacturing efficiency for the RNS System, as higher production volumes allowed fixed overhead costs to be spread over more units. This benefit was partially offset by the lower gross margin associated with the DIXI Medical distribution business. Operating expenses increased by a more modest 8% year-over-year in Q1 2025, totaling $22.5 million. This reflects disciplined expense management, particularly in selling, general, and administrative costs, while strategically increasing investment in research and development to support product development and clinical trials. The resulting operating leverage, with revenue growth significantly outpacing expense growth, contributed to a reduced loss from operations of $5.1 million compared to $7.5 million in the prior year.

A significant strategic decision announced in March 2025 was the planned termination of the exclusive distribution agreement with DIXI Medical, set to expire on September 30, 2025, followed by a wind-down period through Q1 2026. While DIXI product sales contributed approximately 17% of total revenue in 2024, the decision was driven by a strategic refocusing on the higher-margin core RNS business. Management stated that this change is expected to enhance the company's long-term margin profile and does not anticipate a material impact on 2025 revenue due to the ability to sell remaining inventory during the wind-down. Crucially, this decision does not alter the company's long-range plan expectations of achieving a 20%+ annual revenue CAGR through 2027 and reaching cash flow breakeven by year-end 2027.

Execution of the multi-phase growth strategy is progressing. The foundational pillar, increasing adoption and utilization within Level 4 CECs, continues to show strength, with the company reporting record levels of active RNS prescribers. The second pillar, expanding site of service through Project CARE, initiated in 2024, is gaining momentum. This pilot program targets clinicians outside Level 4 centers and has begun to show increasing implants and referrals, indicating success in broadening awareness and access to RNS therapy. Investment in expanding the commercial team, with new hires completing training and focusing on these expansion geographies, is intended to accelerate this initiative through 2025. The third pillar, expanding indications for the RNS System, is advancing through key clinical trials. The NAUTILUS study for idiopathic generalized epilepsy completed patient follow-up in March 2025, with preliminary one-year data analysis underway. FDA submission for this potential new indication is planned for the second half of 2025. Similarly, the company is leveraging real-world data in collaboration with NEST and the FDA to support an expanded indication for pediatric focal epilepsy patients, with submission also targeted for the second half of 2025. These potential label expansions represent significant future market opportunities that could substantially increase the addressable patient population for the RNS System. ## Financial Health and Future Outlook As of March 31, 2025, NeuroPace held cash, cash equivalents, and short-term investments totaling $66.3 million. The company has historically funded its operations through a combination of product sales, equity issuances, and debt financing. Operating activities utilized $7.5 million in cash during Q1 2025.

A significant development in strengthening the balance sheet occurred in February 2025 with the completion of a follow-on equity offering that generated $69.7 million in net proceeds. A portion of these proceeds ($49.5 million) was used to repurchase shares from a significant stockholder, KCK Ltd., facilitating an organized exit and addressing potential stock overhang. The company also terminated its At-the-Market (ATM) offering program in February 2025. Subsequent to the first quarter, in June 2025, NeuroPace further enhanced its financial flexibility by securing a new $75 million credit facility with MidCap Financial, comprising a term loan and a revolving credit facility, the proceeds of which were used to fully repay the prior Term Loan with CRG Partners. These financing activities are expected to provide sufficient capital to fund planned operations through to achieving cash flow breakeven.

For the full year 2025, NeuroPace has increased its revenue guidance to a range of $93 million to $97 million, representing anticipated growth of approximately 16% to 21% over 2024. This outlook is primarily driven by expected continued growth in RNS System sales, with DIXI Medical product sales contributing meaningfully until the wind-down period begins. Gross margin is projected to be in the range of 73% to 75% for 2025, reflecting the anticipated mix of products and ongoing manufacturing efficiencies, with minimal expected impact from recent U.S. government tariffs. Operating expenses for 2025 are guided to be between $92 million and $95 million, including approximately $11 million in stock-based compensation, indicating continued investment in growth initiatives while maintaining cost discipline. Management anticipates a revenue cadence similar to prior years, with the second half typically stronger than the first. The company's long-range plan targets a 20%+ annual revenue CAGR through 2027 and achieving cash flow breakeven by the end of 2027. These targets remain unchanged despite the planned exit from the DIXI distribution business, underscoring confidence in the growth potential of the core RNS franchise and the impact of strategic expansion efforts. As of March 31, 2025, NeuroPace was in compliance with the financial covenants of its Term Loan, including the minimum annual net revenue covenant ($70 million for 2025) and minimum cash balance ($5 million). ## Risks and Considerations While NeuroPace demonstrates promising growth and strategic execution, investors should consider several key risks. The company has a history of net losses and expects to continue incurring losses for the foreseeable future as it invests in growth. Achieving and sustaining profitability is not guaranteed. The Term Loan agreement contains financial maintenance covenants, including minimum revenue thresholds. While currently compliant, failure to meet these covenants in the future could lead to an event of default, requiring immediate repayment and potentially impacting the company's ability to continue as a going concern if additional capital is not secured. The ability to raise future capital, if needed, could be adversely affected by global economic conditions and financial market volatility. If unable to secure funding, the company may need to curtail planned commercialization or product development activities. Competition in the neuromodulation market is intense, with larger players possessing greater resources and established relationships. NeuroPace's ability to compete successfully depends on continued demonstration of clinical superiority, effective market penetration, and successful execution of its expansion strategies. Regulatory risks are significant. The RNS System and future modifications or expanded indications are subject to extensive FDA requirements. Delays or inability to obtain necessary clearances or approvals, including for the generalized and pediatric indications, could harm growth potential. Compliance with ongoing regulatory requirements, including manufacturing and quality systems, is costly, and failure to comply could result in enforcement actions or product recalls. The company relies on a limited number of single-source suppliers for critical components, creating vulnerability to supply shortages or price fluctuations. Accurate forecasting of customer demand is essential to manage inventory and avoid write-downs or shortages. The success of the RNS System depends on appropriate training of neurosurgeons for implantation and epileptologists for programming and ongoing patient care. Inadequate training could lead to negative patient outcomes and harm adoption. Maintaining adequate reimbursement for RNS procedures and ongoing care is crucial, and changes in coverage or rates could diminish sales or profitability. Finally, the company's growth prospects depend on the successful execution of strategic initiatives like Project CARE and the ability to effectively leverage its unique data asset and analysis capabilities. ## Conclusion NeuroPace is positioning itself as a leader in personalized, brain-responsive neuromodulation for drug-resistant epilepsy, leveraging its clinically differentiated RNS System. The company's recent financial performance, marked by strong revenue growth in its core RNS business and improving margins, reflects solid execution against its multi-phase growth strategy. Key initiatives aimed at expanding access through Project CARE and pursuing significant new indications in generalized and pediatric epilepsy populations are expected to drive future growth and broaden the addressable market. While challenges remain, including competition from larger players and the need to manage expenses on the path to profitability, the company's strengthened balance sheet provides a foundation to fund planned operations through to cash flow breakeven. The strategic decision to exit the lower-margin DIXI distribution business underscores a focus on enhancing the long-term financial profile and doubling down on the core RNS opportunity. Investors should monitor progress on clinical trial readouts and FDA submissions, the expansion of the Project CARE program, and the company's ability to maintain its growth trajectory and financial discipline as it works towards its long-range targets.
