I've come across several CNC Machine shops that look interesting on the surface. One in particular is based in the Southwest and has a long family history with the owner nearing retirement. I've read the IBIS industry report and have an overall understanding of the industry.

This particular machine shop has high customer concentration with 90% of the business from Boeing and lacks CMMC certification. The broker states the company is halfway to CMMC but I realize achieving CMMC certification is an in-depth and time-consuming process. The revenues appear stable at 6mm over the last few years.

Is anyone operating a machine shop in the aerospace and defense sector with this level of customer concentration? Additionally, can anyone shed some color on the CMMC process in terms of timeline, cost, and benefit post-certification?

Thank you.
