Stout Advises on Sale of Plymouth Tube Company’s Winamac, Indiana, Facility

Stout is pleased to announce that Plymouth Tube Company (“Plymouth”) has completed the sale of its Winamac, Indiana, Carbon & Alloy Seamless Tube Mill (“Winamac”) to an affiliate of Shadowbriar Capital Partners (“Shadowbriar”). Stout served as the exclusive financial advisor to Plymouth for this transaction, which marks a strategic move for the company as it sharpens its focus on core specialty markets.

Founded in 1924, Plymouth is a global leader in specialty precision steel tubing, including stainless, nickel alloy, and carbon alloy tubing, with a particular emphasis on aerospace, defense, medical, nuclear, and fluid power markets. Headquartered in Warrenville, Illinois, and celebrating five continuous generations of family ownership, Plymouth is committed to delivering innovative, high-quality tubing solutions through its extensive manufacturing capabilities and customer-centered approach. The sale of the Winamac facility aligns with Plymouth’s strategy to enhance its product leadership in high-performance specialty markets, following the closure of its West Monroe, Louisiana, site earlier this year.

“We are grateful to the Winamac employees for their significant contributions since 1962 and are excited for their future under Shadowbriar’s ownership,” said Paul Lemke, Board Chair of Plymouth Tube Company. “This transaction allows Plymouth to further its focus on specialty markets, increasing the differentiated value we bring to our customers.”

The Winamac facility, which includes a cold draw, hot mill, and quench and temper line, manufactures carbon and alloy seamless steel tubing for a range of demanding applications, including construction, drilling, utilities, military, oil and gas, and other industrial sectors. Under its new name, Crossroads Seamless USA, the facility will continue to support a diverse customer base across North America.

“We see tremendous potential with Crossroads Seamless USA’s established manufacturing capabilities and skilled workforce,” said George Thompson, the newly appointed President of Crossroads Seamless USA, with over 35 years of industry experience. “We’re looking forward to expanding production volumes and processing capabilities to deliver greater value to our clients.”

Shadowbriar Capital Partners, based in Los Angeles, is a private equity firm specializing in industrial businesses with strong growth potential. With investments across metal processing and related sectors, Shadowbriar leverages its proven growth strategy to support long-term value creation.

Matt Homme, Managing Partner of Shadowbriar, shared, “We’re confident that George Thompson’s leadership will help Crossroads Seamless USA thrive, working alongside the company’s dedicated team to achieve significant growth.”

Mike Jenny, Stout’s Managing Director and Head of Metals & Specialty Manufacturing, shared, “This transaction exemplifies Stout’s commitment to providing value-driven advisory services that align with the strategic goals of our clients. It was a privilege to support Plymouth Tube Company in positioning the Winamac facility for continued success under new ownership.”

Stout’s Kevin Mayer, Zach Ryan, Luke Korney, and Carson Roth also supported the successful execution of this transaction.
