Transaction shifts control of a major North American environmental testing and compliance platform from Morgan Stanley Capital Partners to Blackstone, reinforcing private equity appetite for regulated environmental services.
Alliance Technical Group’s growth highlights rising demand for compliance, monitoring, and laboratory services as environmental regulation tightens across the US and Canada.
The deal underscores environmental services as a defensive, policy driven investment theme tied to ESG disclosure, industrial compliance, and regulatory enforcement.
A Strategic Exit in a Growing Compliance Market
Morgan Stanley Capital Partners has completed the sale of Alliance Technical Group, one of North America’s largest providers of environmental testing and compliance services, to private equity funds affiliated with Blackstone. Financial terms of the transaction were not disclosed.
The sale marks the end of a four year investment cycle for Morgan Stanley Capital Partners, the middle market private equity arm of Morgan Stanley Investment Management, and places Alliance under the ownership of one of the world’s largest alternative asset managers. The transaction reflects continued investor interest in environmental services businesses positioned at the intersection of regulation, industrial operations, and ESG compliance.
Alliance operates in a segment that has grown steadily as environmental standards become more complex and enforcement more consistent. Industrial facilities, utilities, and infrastructure operators increasingly rely on third party testing, monitoring, and certification providers to meet federal, state, and provincial requirements.
From Regional Operator to National Platform
Founded in 2000 as a small stack testing business, Alliance has evolved into a comprehensive environmental services platform with more than 2,200 employees across more than 60 offices in the United States and Canada. Its service offering spans environmental compliance, on site testing and monitoring, and laboratory testing and analysis.
Since Morgan Stanley Capital Partners invested in the business in 2021, Alliance has pursued a multi pronged growth strategy. That approach combined organic expansion, targeted acquisitions, entry into adjacent service lines, technology investment, and the creation of an integrated national operating platform.
These initiatives broadened the company’s technical capabilities and positioned it as a partner to clients navigating tightening environmental regulations and expanding disclosure requirements. The scale achieved under Morgan Stanley ownership reflects a broader consolidation trend across environmental testing, inspection, certification, and compliance services.
Morgan Stanley’s Investment Thesis
Eric Kanter, Head of Industrial Services for Morgan Stanley Capital Partners, emphasized the strategic transformation achieved during the firm’s ownership period.
“We’re proud to have partnered with Chris LeMay and the entire Alliance team to accelerate the company’s growth and advance its mission to deliver comprehensive environmental solutions. Over the course of our partnership, the team built a truly differentiated and unique business within Environmental Testing, Inspection, Certification, and Compliance, which we believe is well positioned for continued success. We are extremely grateful for their hard work and dedication and look forward to seeing the company’s next chapter unfold.”
For Morgan Stanley Capital Partners, the exit highlights how environmental services have become a core industrial investment theme, driven by regulatory pressure rather than discretionary spending cycles. Compliance requirements tend to persist regardless of macroeconomic conditions, making the sector attractive to long term financial sponsors.

Blackstone’s Entry and the Next Phase
For Alliance, the transaction opens a new chapter under Blackstone ownership. The firm has expanded its exposure to environmental, infrastructure, and services assets aligned with long term regulatory and sustainability trends.
Chris LeMay, Chief Executive Officer of Alliance Technical Group, pointed to continuity and further investment as key priorities under the new ownership structure.
“Our partnership with MSCP accelerated Alliance’s growth and enabled us to build a more diversified, integrated environmental services platform while staying true to our culture and client first approach. I’m incredibly proud of our team’s dedication and execution over the past several years. As we look ahead, we’re excited to partner with Blackstone to continue investing in our people, strengthening our processes, and delivering industry leading technology for our clients.”
What Executives and Investors Should Take Away
The sale illustrates how environmental compliance services have moved from niche support functions to critical infrastructure for regulated industries. As governments expand climate related regulation, emissions monitoring, and disclosure requirements, demand for specialized testing and certification continues to rise.
For C suite leaders, the transaction signals that environmental compliance capacity is becoming a strategic asset rather than a cost center. For investors, it reinforces the view that regulatory driven services can offer durable growth and downside protection.
Piper Sandler & Co. served as financial advisor to Alliance, with support from Robert W. Baird & Co, Houlihan Lokey, and Environmental Financial Consulting Group. Jones Day acted as legal advisor to Morgan Stanley Capital Partners.
At a time when ESG oversight is intensifying across North America, the transfer of Alliance from Morgan Stanley Capital Partners to Blackstone highlights how private capital continues to consolidate and scale the infrastructure underpinning environmental regulation itself.
