Quad-C Buys Warren’s Industrial Services Platform

Quad-C Management has acquired O6 Environmental, a provider of environmental remediation and industrial services, and a portfolio company of Warren Equity since June 2022.

O6 provides waste management, site cleanup, and emergency response services to utilities, where environmental compliance and site remediation are often required; government agencies, which contract O6 for both planned and emergency cleanup projects; and manufacturing and energy infrastructure firms that require scheduled waste management and cleaning services to maintain operations. Construction companies also utilize O6 for site assessments and waste removal during and after project completion.

Specific examples of O6’s services include the removal of pollutants from soil, groundwater, or surface water; industrial cleaning services for plants, equipment, and facilities; non-hazardous liquid waste processing; and third-party waste disposal and rapid-response services for chemical spills and infrastructure failures.

O6 serves customers primarily in the central and southeastern United States and focuses on small to mid-sized contracts, which, according to the company, tend to carry more stable margins and reduced volatility compared to large-scale industrial bids. O6 was founded in 2014 by CEO Dan Giesler and is headquartered in St. Louis.

“We are excited to enter our next phase of growth in partnership with Quad-C,” said Mr. Giesler. “The Quad-C team has an established track record as a collaborative and value-added partner to management teams. We believe their operational expertise and deep experience within industrials and infrastructure services will be instrumental as we continue to drive growth.”

“We are thrilled to welcome O6 Environmental to our industrial services portfolio,” said Tom Hickey, a senior partner at Quad-C. “Dan and his team have done a tremendous job building a leading environmental services platform known for its excellent customer service, safety and technical capabilities.”l

The environmental services sector is being shaped by tighter regulations, more industrial outsourcing, and growing demand for compliance-driven expertise. O6 is focused on a specific part of that market—remediation, industrial cleaning, and waste handling—which are services that utilities, manufacturers, and infrastructure players are outsourcing more often to reduce liability and manage risk.

IBISWorld projects that the U.S. environmental consulting market, which overlaps quite a bit with our space, will grow at 2.8% annually through 2030. That’s being driven by increased demand from construction, energy, and public sector clients, along with more aggressive enforcement from both federal and state environmental regulators. On top of that, the Infrastructure Investment and Jobs Act (IIJA) is still fueling contract activity tied to federally funded infrastructure upgrades.

At the same time, industrial clients are facing more pressure around waste, air, and water compliance—so they’re leaning more heavily on third-party providers to manage field work and ensure they’re aligned with regulations. This shift toward non-optional environmental spending means that firms like O6, which focus on frequent, mid-size cleanup and remediation projects, are well positioned to capture steady contract volume and repeat business across both the public and private sectors.

“We look forward to working in partnership with the O6 Environmental team to expand its geographic footprint, broaden its service offerings and leverage tailwinds within the industry,” said Matt Trotta, a principal at Quad-C.

Quad-C invests from $50 million to $150 million of equity in North America-based service and industrial companies with enterprise values of $100 million to $500 million. The firm was founded in 1989 and is headquartered in Charlottesville, Virginia. Quad-C is currently investing from its tenth fund, Quad-C Partners X LP, which closed in May 2022 with $1.7 billion in capital.

Warren Equity invests from $5 million to $40 million in North American-based companies that have from $3 million to $15 million of EBITDA and total enterprise value of less than $150 million. Sectors of interest include industrial services, industrial products, business services, and distribution. In April 2023, the firm closed its fourth flagship fund, Warren Equity Partners Fund IV LP, with over $1.4 billion in hard cap capital commitments. Warren Equity was founded in mid-2015 by Steven Wacaster, Scott Bruckmann, and Henrik Dahlback and is headquartered in Jacksonville, Florida.

Harris Williams was the financial advisor to O6 on this transaction and Piper Sandler advised Quad-C.
