NorthStar

What NorthStar does

NorthStar Services, Inc. is a privately held, Delaware-chartered infrastructure and environmental solutions company founded in 1986 and headquartered in New York City. The company provides integrated demolition, decontamination and decommissioning (D&D), environmental remediation, hazardous material abatement (asbestos, lead, mold, radon), nuclear facility decommissioning, and 24/7 emergency response services to federal and state government agencies, utilities, and commercial clients across all 50 U.S. states. With reported average annual revenue above $700 million and 3,000+ employees following the Trans Ash acquisition, NorthStar operates one of the largest company-owned demolition fleets in the industry, supported by 18+ regional branch offices and proprietary technologies including the Pneumatic Separation Unit (PSU), high-pressure water jetting systems, in-situ thermal treatment, and a real-time, fully integrated cost accounting platform.

The company's service portfolio spans six core offerings — Facility Demolition, Nuclear Services, Facility Response, Environmental Services (including coal ash management), Facility Abatement, and Response & Restoration — delivered through wholly owned operations and subsidiaries such as NorthStar Recovery Services (NRS) and the Accelerated Decommissioning Partners joint venture with Orano USA. NorthStar holds rare Nuclear Regulatory Commission license transfers for Vermont Yankee and Crystal River, and was awarded a $418.5 million U.S. Navy contract in August 2026 to dismantle the former USS Enterprise nuclear aircraft carrier, with completion targeted for September 2030. The company is a portfolio company of J.F. Lehman & Company and is ranked by ENR as the #1 Demolition Contractor in the World since 2007 and #1 Abatement Contractor since 1999.

NorthStar's business model is primarily project-based, with the majority of engagements structured as fixed-price contracts (multi-million to multi-hundred-million dollar values) that transfer cost and schedule risk to NorthStar in exchange for project margin. Revenue is complemented by Master Service Agreements (MSAs) that provide preferred status and pre-negotiated pricing to multi-facility enterprise and government clients, as well as asset recovery income from scrap sales and material disposition. Following the January 2023 acquisition of Trans Ash Inc., the company holds over $3.5 billion in coal ash remediation backlog, and customers include the Department of Energy, Department of Defense, NASA, Army Corps of Engineers, Duke Energy, Florida Power & Light, Boeing, Lockheed Martin, Raytheon, Goldman Sachs, JP Morgan, Mass General Hospital, and the Ritz Carlton. The CEO succession effective July 14, 2026 elevated Jeffrey Adix (formerly CFO) to Chief Executive Officer, with Scott State transitioning to Executive Chairman while retaining the Chief Nuclear Officer role.
