Midwest Composite Technologies, a portfolio company of Core Industrial Partners, has acquired Fathom. Financial terms weren’t announced. Fathom is an advanced manufacturer with an expertise in 3D printing and additive manufacturing.




Chicago, IL, September 26, 2019 – CORE Industrial Partners (“CORE”), a Chicago-based private equity firm, announced today the acquisition of FATHOM (the “Company”), an advanced manufacturer with an expertise in 3D printing and additive manufacturing, by CORE portfolio company Midwest Composite Technologies (“MCT”), to form one of the largest global independent additive manufacturing companies.  The combined company has over 80 3D printing machines encompassing a wide variety of additive technologies and a large footprint with over 150,000 square feet of manufacturing capacity across three facilities.  Financial terms of the transaction were not disclosed.


Headquartered in Oakland, with a second facility in Seattle, FATHOM combines a broad array of in-house additive manufacturing technologies, including fused deposition modeling, multi jet fusion, polyjet printing, selective laser sintering and stereolithography, along with CNC machining, urethane casting, tooling and injection molding capabilities.  FATHOM’s expertise in both additive and traditional manufacturing allows the Company to offer hybridized solutions that uniquely blend both subtractive and formative methods to push the bounds of innovative product design and development.  FATHOM augments its 3D printing manufacturing services with mechanical engineering and industrial design support, as well as on-site managed equipment services.  The Company has been recognized by Inc. Magazine as one of the fastest growing private companies for seven consecutive years and holds an ISO 9001:2015 certification and ITAR registration.


Ryan Martin, Chief Executive Officer of MCT, said, “The acquisition of FATHOM brings together two of the leading additive manufacturing firms in North America.  Both companies offer differentiated engineering expertise, exceptional customer service and a long-tenured track record of successfully partnering with leading companies across myriad end markets to provide the best in modern manufacturing, from prototype to production. We are very pleased to complete this acquisition and look forward to working closely with the FATHOM team to help drive further value into the business.”


Rich Stump, a Principal and Co-Founder at FATHOM, said, “On behalf of my Co-Founder, Michelle, and the entire FATHOM team, we’re proud to partner with CORE and MCT. This is a very exciting time for FATHOM, especially given the growing demand for dynamic additive manufacturing services to transform how products are designed and manufactured.  We believe the combination with MCT and support from CORE will give the combined platform considerable scale and the financial resources to invest in cutting-edge technologies and infrastructure to be the most accelerated manufacturer of prototypes and production parts.”


Matthew Puglisi, a Partner at CORE, said, “The acquisition of FATHOM aligns well with our previously stated intention to build a leading Industry 4.0 additive manufacturing company.  From customer bases to technical expertise and additive manufacturing capabilities, MCT and FATHOM are highly synergistic, and we’re looking forward to further building out the platform through additional complementary acquisitions and continued organic growth.”


Winston & Strawn LLP provided legal representation to CORE and MCT in the transaction.  Stifel Global Technology Group acted as exclusive financial advisor to FATHOM in connection with this transaction.
