Recent Developments

As previously announced, on February 4, 2026, the Company completed the acquisition of J. E. McAmis, Inc. and JEM Marine Leasing LLC (together, “J.E. McAmis” or “McAmis”), for approximately $60 million, net of cash acquired, plus additional contingent consideration. Founded in 1973, J.E. McAmis is a heavy civil contractor with a proven track record for delivering complex marine construction projects in challenging environments with work spanning jetty and breakwater construction, dredging, environmental restoration, and dam and spillway construction. With a highly skilled leadership and operations team, J.E. McAmis has consistently posted high-margin growth over the last several years winning and successfully executing projects primarily in Washington and Oregon andalso Canada, Florida, Alaska and Hawaii. McAmis has strong client relationships with the U.S. Department of Defense and U.S. Army Corp of Engineers, a robust $1.4 billion pipeline of opportunities, and a broad portfolio of marine and real estate assets valued at $34 million.

In late 2025, the Company purchased a large derrick barge to further increase capacity and execution flexibility. This strategic asset will enable our team to pursue a broader range of marine and defense-related work.
