DuBois Chemicals Announces CEO Transition

DuBois Chemicals (“DuBois” or the “Company”), a leading full-service provider of customized specialty chemical solutions, today announced that after more than two decades of leadership, President and CEO Jeff Welsh will transition from his operating role to the company’s Board of Directors. Mr. Welsh, who has led DuBois since spearheading its carve-out as a standalone business in 2008, has played a pivotal role in driving the Company’s substantial growth, both organically and through strategic M&A. Effective February 24, 2025, Mr. Welsh will transition to a position on the Company’s Board of Directors, where he will continue to provide strategic guidance and support to DuBois. John Wolf, an accomplished CEO and senior executive with extensive experience leading and scaling solutions-oriented industrial businesses, will succeed Mr. Welsh as CEO.

“Leading DuBois has been a tremendous privilege, and I am incredibly proud of all that we have accomplished together,” Mr. Welsh said. “The entire DuBois family has worked tirelessly to develop and grow a world-class business delivering innovative custom chemical solutions for our customers. With John at the helm, I am confident that DuBois is well-positioned for continued growth, and I look forward to supporting the Company in my role on the Board of Directors.”

“Jeff has built an incredible business, executing on the vision of expanding DuBois’ portfolio of essential industrial applications that sustain the critical operations of its customers. We thank him for his many years of leadership and greatly appreciate his continued involvement as John transitions into the CEO role,” said Andrew Sheiner, Founder and CEO of Altas Partners, DuBois’ majority owner. “With his track record of driving strategic, high-quality organic growth, John is well-equipped to build on this strong foundation. His dedication to solving problems for customers and entrepreneurial energy make him a natural cultural fit at DuBois, and we look forward to working closely with him to continue DuBois’ successful trajectory.”

Mr. Wolf joins DuBois with more than twenty years of experience leading highly differentiated industrial businesses and driving strategic growth. Most recently, he served as President and CEO of Spectrum Plastics, a leader in the design, development, and manufacturing of specialty polymer products. At Spectrum, he led the business and its 2,500 employees across 19 global facilities, including through its acquisition by strategic buyer DuPont. Prior to that, he served as a commercial leader of North American and global business units across a variety of end-markets at Spectrum and Sealed Air Corporation.

“It is an honor to be appointed as the next CEO of DuBois,” said Mr. Wolf. “The Company has built a strong reputation as a market leader with a dynamic, solutions-oriented team dedicated to supporting its customers' critical operations. I am grateful for the strong business Jeff has built, and I am eager to leverage my experience in leading customer-focused teams to take DuBois to even greater heights in this next chapter.”
