Morgan Stanley Capital Partners, a middle-market private equity platform, completed the acquisition of a majority stake in Apex, a consulting and engineering services company, from Sentinel Capital Partners, a private equity firm. Financial terms were not disclosed. “Apex’s solutions serve clients and communities across a broad range of environmental and infrastructure needs, and seek to ensure that corporations, government agencies and municipalities achieve and maintain regulatory compliance. In addition to being a highly respected provider of environmental services, Apex is also a leader in the attractive and high-growth stormwater compliance industry. We believe the company’s record of expansion, both organically and through accretive M&A, has generated substantial momentum for continued growth. We are excited to partner with Dave and the Apex leadership team to drive continued success in Apex’s core service offerings and to pursue strategic M&A that adds additional geographic presence, service capabilities and customer diversity,” Eric Kanter, MSCP Managing Director and Head of Industrials.
