The company’s management retains a significant stake and will continue to lead the business. CEO Jason Caldwell oversees operations, including a defense logistics and compliance program that offers end‑to‑end supply chain management for military operations.

Tinicum praised the GracoRoberts team’s technical depth, commitment to customer service, and longstanding partnerships with leading material manufacturers. Partner Erik Blumenkranz remarked, "We greatly admire the business that the GracoRoberts team has built."

Harris Williams served as exclusive financial advisor, while Holland & Knight LLP and Goodwin Procter LLP provided legal counsel to GracoRoberts and Tinicum respectively.
