In this article, Robert Cimasi and Matthew Wagner provide a roadmap of the valuation and legal issues valuation professionals confront valuing a medical practice that also provides ancillary and technical component (ASTC) services. The fact that the ASTC services are often integrated with the professional services of a practice does not restrict the ASTC service line from having value separate and aside from that of the practice enterprise. The authors share their views on how to value the hypothetical “carve-out” ASTC, including what approaches to consider.
