Radnostix Inc. INIS

What this company does

Radnostix Inc. (the “Company”, “we”, “us” and “our”) manufactures a wide range of radioisotope-focused products used in variety of medical and industrial applications. On December 23, 2025, we filed a Certificate of Amendment in the state of Texas for the sole purpose of amending our Certificate of Formation to change our corporate name from International Isotopes Inc. to Radnostix, Inc. Our core business consists of five reportable segments which include: Theranostics Products, Cobalt Products, Calibration & Reference Products (previously called Nuclear Medicine Standards), Medical Devices, and Fluorine Products. To our knowledge, our FDA approved generic sodium iodide I-131 drug product is the only generic product of this type manufactured in the U.S. and offers customers an attractive domestic alternative to the single existing foreign commercial drug manufacturer. We started the Medical Devices segment in 2024 and many of our products in this segment remain under development. We established the fluorine products business segment in 2004 to support production and sale of various fluoride gases produced using our Fluorine Extraction Process ("FEP").
