HOUSTON, April 8, 2021 – GulfStar Group (“GulfStar”) is pleased to announce the acquisition of Emission Monitoring Service, Inc. (“EMSI” or the “Company”) by Alliance Technical Group (“Alliance”), a portfolio company of Align Capital Partners LLC (“ACP”). GulfStar served as the exclusive financial advisor to EMSI throughout the transaction, which closed on April 1, 2021.

Founded in 1986 and headquartered in Baytown, Texas, EMSI is a leading environmental services company providing emissions leak detection and repair services. The Company designs and administers programs necessary for client compliance with a complex array of federal, state and local environmental regulations. EMSI employs more than 300 technicians within some of the largest refineries, petrochemical, natural gas processing, oil and gas pipeline, and specialty chemical plants in the United States. It serves more than 150 facilities in 38 states across the nation, with a leading presence in the Gulf Coast region.

“The expertise and guidance contributed by GulfStar throughout the process were integral to the success of this transaction,” said Paul Phillips, president of EMSI. “Managing the tasks associated with a sale while also running the daily operations of a business is a daunting task, and the support of the GulfStar team made it possible to succeed in accomplishing both.”

Headquartered in Decatur, Alabama, Alliance is the leading provider of source emission testing and monitoring solutions to customers throughout the United States. With expertise in a variety of test methods, Alliance is uniquely qualified to provide customers with the highest quality and most cost-effective source testing solutions available.

“GulfStar greatly appreciated the opportunity to advise EMSI, its owners and executives in this process,” said Bryan Frederickson, managing director of GulfStar. “The resulting transaction enabled an absentee majority owner to recognize liquidity in her holdings while providing the management team with leadership opportunities within Alliance. We found our interactions with ACP and Alliance to be constructive and collaborative, and wish the combined companies well as they continue aggressively growing the business.”

The GulfStar team was led by Managing Director Bryan Frederickson with support from Senior Vice President Ben Stanton and Analyst Brodie Sherman.

Norton Rose Fulbright served as EMSI’s legal counsel. Moss Adams provided transaction accounting services to the seller.
