I understand that there is a great deal of mainframe-era enterprise software that is still in active use, if not on the original hardware then in emulated environments. Its users keep it running because it still works for its intended use cases and because the cost of reimplementing it in a modern language, on modern hardware and operating systems, is therefore not justified. Similarly, some businesses continue to use MS-DOS and OS/2 today, despite them being long ago EOL'd by Microsoft and IBM, respectively. There are apparently enough active DOS and OS/2 users to support at least one company providing third-party legacy support.
Is the same true of CP/M? That is, are there any enterprise users that continue to maintain and run CP/M installations for their original purposes? (Note that I am not talking about running CP/M as a retrocomputing hobby or as museum piece.) Wikipedia claims that, besides vintage computer enthusiasts, there exist "some small commercial businesses, still developing and supporting computer platforms that use CP/M (mostly 2.2) as the host operating system", but no examples or references are provided.
