The story

Founded in 1968, as Input/Output (I/O), ION began as a provider of highly specialized, seismic source synchronization equipment. ION was publicly traded on NASDAQ in 1991, and was listed on the New York Stock Exchange in November 1994 using the trading symbol "IO". Throughout the 1990s and 2000s ION experienced growth through a number of key acquisitions. In September 2007 Input / Output (I/O) officially changed its name to "ION" as part of a re-branding. The company filed for bankruptcy in the spring of 2022. In July 2022, the company announced that it would sell of parts of its assets and ceased operations during the bankruptcy procedure. The company completed its bankruptcy reorganization and exited Chapter 11 bankruptcy by September 2022.
