Senseonics Holdings, Inc. (NYSE American: SENS) has launched a $50 million public offering of common stock alongside a concurrent $25 million private placement with Abbott Laboratories to fund the commercial rollout of its long-term implantable continuous glucose monitoring (CGM) technology.
The Germantown, Maryland-based medical technology company announced on May 15, 2025, that it has commenced an underwritten public offering of its common stock, subject to market and other conditions. In addition to the public offering, Abbott Laboratories has agreed to purchase up to $25 million of Senseonics' common stock in a separate private placement at the public offering price.
TD Cowen and Barclays are acting as joint book-running managers for the offering, with RBC Capital Markets and Lake Street serving as additional bookrunners. Senseonics plans to grant the underwriters a 30-day option to purchase up to an additional 15% of the total number of shares offered in the public offering.
Funding the Future of Implantable CGM Technology
Senseonics intends to use the net proceeds from both transactions to fund the ongoing commercial launch of Eversense 365 and continue development of its pipeline products, as well as for working capital and general corporate purposes.
The Eversense CGM system represents a significant advancement in diabetes management technology. Unlike traditional CGM systems that require frequent sensor replacements, Senseonics' Eversense 365 features a small sensor inserted completely under the skin that can remain in place for up to one year. The sensor communicates with a smart transmitter worn over the insertion site, automatically sending glucose data every 5 minutes to a mobile app on the user's smartphone.
This long-term implantable approach offers potential advantages for patients with diabetes, including reduced insertion procedures, consistent glucose monitoring, and elimination of the need for frequent sensor replacements.
Strategic Investment from Abbott
Abbott's $25 million investment in Senseonics signals strategic interest in the implantable CGM market. Abbott, already a major player in diabetes care with its FreeStyle Libre flash glucose monitoring system, appears to be expanding its portfolio through this investment in long-term implantable technology.
The concurrent private placement is subject to the closing of the public offering and other customary closing conditions, according to the company's announcement.
Market Context and Regulatory Details
The public offering is being made pursuant to a "shelf" registration statement on Form S-3 that was filed with the Securities and Exchange Commission on August 10, 2023, and became effective on September 12, 2023. A preliminary prospectus supplement and accompanying prospectus relating to the offering will be filed with the SEC.
Senseonics has emphasized that the proposed offering is subject to market and other conditions, with no assurance as to whether or when it may be completed, or the actual size or terms of the offering.
Competitive Landscape in Diabetes Management
The diabetes monitoring market continues to evolve rapidly, with companies competing to provide more convenient, accurate, and longer-lasting solutions for the millions of people living with diabetes worldwide. Senseonics' Eversense technology represents one approach to addressing the challenges of continuous glucose monitoring, focusing on extended wear time to reduce the burden of frequent sensor changes.
The company's Eversense product line includes both the Eversense 365 and Eversense E3 systems, providing options for patients seeking long-term implantable glucose monitoring solutions.
As diabetes prevalence continues to rise globally, the market for advanced monitoring technologies is expected to expand significantly in the coming years, with implantable sensors potentially capturing an increasing share of this growing market.
