Morgan Stanley Capital Partners (MSCP) has acquired Apex Companies, a provider of environmental consulting and engineering services, from Sentinel Capital Partners which will maintain a minority interest in the company post-closing. Sentinel first invested in Apex in November 2018.
Apex specializes in assessing, preventing, and curing environmental issues related to water, ground, facilities, and air quality. The company’s public and private sector customers are active in a range of end markets including energy, industrial, manufacturing, real estate, retail, and telecom.

Apex’s environmental compliance and risk services team includes more than 700 geologists, hydrogeologists, engineers, air quality specialists, environmental scientists, information management experts, industrial hygienists, and field technicians. The company, led by CEO Dave Fabianski, was founded in 1988 and is headquartered near Washington DC in Rockville, Maryland.
MSCP is partnering on this transaction with Mr. Fabianski, who will continue as CEO, and other members of the company’s management team.

MSCP’s acquisition of Apex is the firm’s second investment in an environmental services company following the July 2021 acquisition of Alliance Technical Group (ATG) from Align Capital Partners. Alabama-based ATG provides source testing, emissions monitoring, and analytical services to industrial facilities for permitting and compliance in accordance with air-quality mandates from local, state and federal regulatory bodies. The company services customers’ facilities on a repeated basis, with the frequency determined by regulations for each industry. In December 2022, ATG closed the add-on acquisition of GBMc & Associates, an Arkansas-based environmental consulting firm.

MSCP is the middle-market-focused private equity business of Morgan Stanley Investment Management which in turn is part of Morgan Stanley, a financial services firm providing investment banking, securities, wealth management, and investment management services. MSCP invests in North American-based companies that are active in the business services, consumer, healthcare and industrial markets.
Carlyle and Churchill Asset Management were the administrative agents, bookrunners, and arrangers on the financing to back MSCP’s buy of Apex.
