## TL;DR

Ionetix is a Michigan company that makes radioactive isotopes with compact cyclotrons. It supplies isotopes for PET scans and produces the alpha-emitting isotopes actinium-225 and astatine-211 that newer cancer radiotherapy drugs are built on.

## Summary

Ionetix Corporation, of Lansing, Michigan, incorporated in Delaware in 2009 to develop smaller superconducting cyclotrons, filed for an initial public offering in October 2026. Its cyclotrons are cryogen-free and need no liquid helium. In diagnostics it produces ammonia N-13 at nine production sites under an Abbreviated New Drug Application, and other PET isotopes including fluorine-18 and gallium-68. In therapeutics it produces the alpha-emitting isotopes actinium-225, using a cyclotron bought from a third-party maker, and astatine-211 for use in oncology therapeutics. The company says it no longer intends to sell cyclotrons.
