SINTX Technologies Inc (NASDAQ: SINT) is a biomaterials and medical device company that designs, manufactures, and sells silicon nitride (SiN) ceramic products for spinal fusion, joint replacement, and antipathogenic applications. Revenue comes from direct product sales of silicon nitride implants and advanced ceramic powders, supplemented by consulting, product development, and royalty arrangements with surgeons and healthcare professionals. The company operates a 30,764 square foot corporate facility in Salt Lake City, Utah, which includes 19,000 square feet of FDA-registered, ISO 13485:2016 certified, and AS9100D certified manufacturing space. Products are primarily sold in the United States. SINTX has manufactured silicon nitride spinal implants for over 10 years and is pursuing expanded applications in foot and ankle, dental, maxillofacial, and arthroplasty markets, as well as antipathogenic products incorporating silicon nitride powder. The company has received three NIH grants to develop 3D printed silicon nitride and polymer implantable medical devices. Financing activity in FY2025 provided $8.2 million, primarily from warrant exercises and ATM common stock issuances, indicating reliance on equity markets rather than operating cash flow.
