Fathom to commence trading on the New York Stock Exchange under the ticker “FATH” on Monday, December 27, 2021

Fathom Digital Manufacturing Corp. (“Fathom” or the “Company”), an industry leader in on-demand digital manufacturing services, today announced the completion of its previously announced business combination with Altimar Acquisition Corp. II (“Altimar”), a special purpose acquisition company. The business combination, which was approved by a vote of Altimar’s shareholders, closed on December 23, 2021. Prior to the business combination, Fathom was a privately held portfolio company of CORE Industrial Partners (“CORE”), a Chicago-based private equity firm focused on investing in and growing middle-market manufacturing, industrial technology and industrial services businesses. CORE will remain the largest shareholder in the combined business.

Fathom will continue to be led by Chief Executive Officer Ryan Martin, Chief Financial Officer Mark Frost, Chief Commercial Officer Rich Stump, and Chairman of the Board TJ Chung, who all have substantial experience in on-demand digital manufacturing services.

Fathom delivers a wide breadth of advanced manufacturing services through a differentiated technology-agnostic strategy focused on speed, problem solving, adaptive technical responsiveness and manufacturing expertise, allowing companies to iterate faster and shorten their product development and production cycles. Fathom also enables customers to both consolidate and localize their supply chains driven by the shift to Industry 4.0, the digitization of manufacturing, providing significant growth opportunities in the fragmented $25 billion low-to-mid volume manufacturing market. By continuing to leverage its proven business model, Fathom has secured new business wins with large innovative companies, achieving continued market penetration for its additive and traditional manufacturing technologies and growing its backlog of business.

“We are taking this step because we are a strong, profitable company, and believe our NYSE listing will accelerate Fathom’s growth, both organically and inorganically, by using our stock as a currency to advance our M&A strategy and investing in promising new technologies across the industry,” said Mr. Martin. “These new technologies will enable us to serve our target markets with greater efficiency and responsiveness than ever before. Our broad capabilities from rapid prototyping to low- to mid-volume production, proprietary software suite, engineering expertise and comprehensive support system are competitive advantages we expect will enable us to continue executing our strategic plan and delivering strong profitable growth.”

“Fathom offers an exciting new paradigm – fast, technologically sophisticated, flexible, and geared for rapid growth,” said Mr. Chung, Senior Partner at CORE. “This is an opportunity for us to increase our product offerings to better serve our clients and power their accelerating pace of new product development and manufacturing innovation while expanding both our geographic and strategic reach.”

“With the completion of this transaction, Fathom has solidified its position at the forefront of the fast-growing on-demand digital manufacturing sector,” said John May, Founder and Managing Partner of CORE. “The Company’s unique on-demand platform and diverse offerings serve a broad variety of customers, ranging from the Fortune 500 to high-growth disruptive startups, and are perfectly suited to the challenges and opportunities facing manufacturers today. We are extremely proud of the incredible growth and innovation the Fathom team has achieved over the past three years since we initially partnered with the Company, and we’re excited to remain Fathom’s largest investor. We are confident Fathom’s solid foundation will enable the Company to achieve further success in the public markets.”

Morgan Securities LLC and Stifel served as joint placement agents and capital markets advisors, and Paul, Weiss, Rifkind, Wharton & Garrison LLP served as legal counsel to Altimar.
