To address these challenges, Stereotaxis developed a comprehensive strategy focused on four key pillars: making the robot widely available through technological innovation, building an ecosystem of compatible catheters and integrations in the electrophysiology market, developing a broader portfolio of interventional devices to expand the platform's clinical applications, and establishing additional backbone connectivity and AI capabilities. Over the past decade, Stereotaxis has invested significant effort and resources to advance these strategic initiatives.
Financials
Stereotaxis' financial performance has been marked by a focus on sustainable growth and strategic investments. For the year ended December 31, 2024, the company reported total revenue of $26.9 million, a slight increase from $26.8 million in the previous year. While the company's system revenue remained relatively flat at $8.6 million in 2024, compared to $8.7 million in 2023, its recurring revenue from disposables, service, and accessories grew to $18.3 million, up from $18.0 million in the prior year. This shift towards a higher proportion of recurring revenue underscores Stereotaxis' strategic emphasis on building a robust "razor-and-blade" business model, leveraging its installed base of robotic systems to drive long-term profitability.
The company's overall gross margin was 54% in 2024 compared to 56% in 2023, with the decrease primarily due to changes in product mix. Stereotaxis continues to invest in research and development, with R&D expenses of $9.8 million in 2024 compared to $10.3 million in 2023. Sales and marketing expenses remained consistent at $12.4 million in both 2024 and 2023, while general and administrative expenses increased from $14.1 million to $17.2 million, driven by the remeasurement of contingent consideration and higher administrative costs related to the acquisition of Access Point Technologies EP, Inc. in 2024.
For the full year 2024, Stereotaxis reported a net loss of $24.1 million. The company's adjusted net loss, excluding non-cash charges, was $12.1 million, an improvement from the prior year's adjusted net loss of $10.2 million. Annual operating cash flow and free cash flow for 2024 were both negative $8.5 million.
In the most recent quarter (Q4 2024), Stereotaxis reported revenue of $6.3 million, representing a 39% increase year-over-year. This growth was driven by a 1400% increase in system revenue to $1.4 million and a 9% increase in recurring revenue to $4.9 million. The increase in recurring revenue was partially offset by continued catheter shortages. The net loss for Q4 2024 was $7.8 million.

One of the key factors contributing to Stereotaxis' success has been its commitment to innovation. The company designs, manufactures, and markets robotic systems, instruments, and information systems for the interventional laboratory. Its primary products include the Genesis RMN System, the GenesisX RMN System, and the Odyssey Solution.
The Genesis RMN System is designed to enable physicians to complete more complex interventional procedures by providing image-guided delivery of catheters through the blood vessels and chambers of the heart to treatment sites. This is achieved using externally applied magnetic fields that govern the motion of the working tip of the catheter, resulting in improved navigation, efficient procedures, and reduced x-ray exposure.
The GenesisX RMN System, the latest generation of the Genesis RMN System, is designed to significantly enhance the accessibility of Robotic Magnetic Navigation by eliminating the lengthy construction cycle necessary to install prior generation RMN systems.
The Odyssey Solution consolidates lab information onto one large integrated display, enabling physicians to view and control all the key information in the operating room. This is designed to improve lab layout and procedure efficiency. The system also features a remote viewing and recording capability called Odyssey Cinema, which delivers synchronized content for optimized workflow, advanced care, and improved productivity.
In 2024, the company made significant strides in expanding its product portfolio, with the regulatory submission of the MAGIC Sweep catheter, the first-ever robotically navigated high-density electrophysiology (EP) mapping catheter. This development not only addresses a longstanding need in the EP field but also positions Stereotaxis to capture a larger share of the growing EP market by providing physicians with a comprehensive suite of robotic solutions.
Furthermore, Stereotaxis made another strategic move in 2024 with the acquisition of Access Point Technologies EP, Inc. (APT), a manufacturer of high-quality diagnostic catheters used in cardiac ablation procedures. This acquisition has not only bolstered Stereotaxis' in-house research and development capabilities but has also strengthened its position in the robotically navigated catheter market, enabling the company to offer a more diverse and integrated product portfolio to its customers.
Expanding Applications
In addition to its focus on EP, Stereotaxis has also made significant strides in expanding the applications of its RMN technology beyond electrophysiology. The company's recent regulatory submission of the EMAGIN 5F catheter, the first in a family of robotically navigated endovascular devices, represents a pivotal milestone in its strategy to become a multi-specialty robotics platform. By leveraging its expertise in precise navigation and control, Stereotaxis aims to address the challenges faced in complex endovascular procedures, such as those encountered in neurointerventional, interventional cardiology, and interventional radiology applications.
