Audax Private Equity completed its acquisition of Integral Consulting from Imperial Capital Group, adding a Seattle-based science and engineering consultancy to its professional services portfolio. Ropes & Gray represented Audax in the transaction. Neither party disclosed terms, though comparable expert witness and regulatory advisory platforms in the $100M–$200M EBITDA range have traded at 10–14x multiples over the past eighteen months.
Integral Consulting provides science, engineering, and environmental advisory services to corporates, law firms, and government agencies navigating regulatory disputes, environmental remediation, and complex litigation. The firm employs roughly 300 consultants across offices in Seattle, Los Angeles, and Washington. Imperial Capital, a London-based private equity group, acquired Integral in 2019 and expanded its footprint in North American environmental and forensic consulting. Audax, managing approximately $70 billion across its platform, has assembled a roster of specialized services firms—tax advisory, actuarial, and now technical expert witness—under its lower-middle-market strategy.
The move matters because Audax is building a coordinated roll-up in high-margin advisory services where client stickiness and regulatory tailwinds create pricing power. Expert witness and environmental consulting have seen accelerated demand tied to climate disclosure mandates, ESG litigation, and federal enforcement activity under both administrations. Integral's revenue mix—roughly 60% litigation support, 40% regulatory and environmental remediation—positions it to capture growth in both lanes. Meanwhile, Audax's portfolio already includes environmental consultancy assets that can cross-sell into Integral's client base, compressing integration timelines and lifting EBITDA margins by 200–300 basis points within twelve months.
Operators should watch whether Audax announces add-on acquisitions in adjacent verticals—forensic accounting, industrial hygiene, or technical expert services—within the next six to nine months. Imperial Capital's exit after a six-year hold suggests the platform reached scale targets but lacked the capital or appetite for the next phase of consolidation. Audax's playbook typically involves three to five tuck-ins per platform company in years two and three post-close. If Integral announces leadership hires in business development or M&A integration by early 2027, expect the roll-up to accelerate.
Audax paid Ropes & Gray to close this, which means the deal survived diligence in a market where science consultancies face heightened scrutiny on expert credibility and engagement concentration risk.
