Baltimore, MD -

Combines Leading Players in Nuclear Power Risk Consulting Services

JENSEN HUGHES (the “Company”), the global market leader in fire protection engineering, fire code consulting, and related life safety services, with specialized capabilities to provide risk informed analysis and consulting services for the nuclear power industry, announced that it has completed the acquisition of Stevenson & Associates (“S&A”). S&A is a leading provider of seismic and other risk and hazard engineering consulting services for the nuclear power industry and also offers structural, civil, and mechanical engineering services for other high value and special performance facilities. JENSEN HUGHES is majority-owned by Gryphon Investors, a middle market private equity firm based in San Francisco, which purchased the Company in partnership with management in December 2015. Terms of this transaction were not disclosed.

The combination of JENSEN HUGHES and S&A brings together two leading firms in the nuclear power consulting industry and increases the technical expertise and resources available to provide risk assessment and other engineering consulting services to protect clients against unusual events, including earthquake, wind, blast, flood, thermal, and vibration hazards. This acquisition will augment the engineering, probabilistic risk assessment, and hazard services that JENSEN HUGHES provides to utility providers worldwide through the Company’s more than 60 offices in North America, Asia, and the Middle East.

“We are very excited to have completed the strategic acquisition of S&A, which is one of the leading firms within the nuclear power engineering services industry and has an attractive niche presence in the non-energy marketplace,” stated JENSEN HUGHES CEO Phil Rogers. “S&A shares with JENSEN HUGHES a strong commitment to technical excellence while possessing innovative capabilities to address clients’ most complex needs.
