Investment Review №356. A Reassessment of Values

Investment Potential

• Company Profile. Centinel Spine manufactures total disc replacement implants for the cervical and lumbar spine, which are designed to preserve mobility as an alternative to spondylodesis. The Pro Disc platform offers four key advantages that are critical for the long-term adoption of total disc replacement (TDR): improved kinematics, durable materials, a broad and customizable range of implants, and an optimized instrument set. The Pro Disc platform has been developed over more than 35 years as a comprehensive suite of systems designed to provide surgeons with flexibility in accommodating a patient’s anatomical characteristics, the severity of the condition, and the goals of the procedure. Manufacturing is outsourced to Hammill Manufacturing, located in Ohio. In the U.S., Centinel sells its products through a sales department supported by 400+ independent distributors.
• Potential Market. Surgical procedures, including those for spondylodesis, are widely used in patients with degenerative disc disease: In 2025, approximately 750,000 instrumented spondylodesis procedures were performed in the U.S. on the cervical and lumbar spine. The company believes that a significant portion of these spondylodesis procedures (~275,000) could have been performed using TDR. Despite this potential, only ~58,000 TDR procedures were made in the U.S. in 2025. Therefore, the addressable U.S. market is estimated at $2.5 billion. Based on data provided by Grand View Research for the TDR market and by iData Research for the spondylodesis market, the TDR and spondylodesis markets grew at a CAGR of approximately 7.7% and 0.6%, respectively, from 2022 to 2025.
• Financial Performance. In 2025, revenue rose 39%, and in the first six months of 2026, it accelerated to 42%. The EBIT margin rose from 2% in 2024 to 15% in the first six months of 2026. At the end of H1 2026, debt on the company’s balance sheet was 52% of total assets.
