Company Description

ConforMIS is a medical technology company that designs, manufactures, and sells patient-specific knee replacement implants. Using a patient’s CT scan, the company creates a 3D model to produce a custom implant, such as its iTotal knee replacement system, that is designed to match an individual's unique anatomy. The process also includes customized, single-use surgical instruments delivered in a pre-sterilized kit. ConforMIS was founded in 2004 in Billerica, Massachusetts, by Dr. Philipp Lang, who was dissatisfied with the limitations of traditional, symmetric implant designs. Since its founding, the company has grown internationally, provided over 137,000 implants, and its technology is supported by more than a decade of clinical evidence.

While the company has not publicly released specific future plans or recent announcements, its stated focus is on continued innovation in personalized knee replacement and helping patients resume daily activities. The company's products have been featured in over 50 clinical studies and more than 30 peer-reviewed publications. In the United Kingdom, ConforMIS has also received a '7A Performance ODEP rating' from the Orthopaedic Data Evaluation Panel, which reflects its established use within the orthopedics field.

Deciding what to do with your private company stock involves creating a strategy for exercising options and selling shares to maximize your returns. Prospect can build a customized, multi-year option exercise strategy to help you manage your equity and minimize your tax burden.
