DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Business Operations Perimeter Solutions, Inc. (the “Company”) is a leading provider of industrial products and services that support critical and complex customer missions across a range of niche applications. Our current operations span firefighting products, lubricant additives, electronic components and, following the acquisition of Medical Manufacturing Technologies, LLC (“MMT”) in January 2026, highly engineered machinery for the medical device industry. The Company conducts its operations globally, with approximately 76% of annual revenues derived in the United States, approximately 10% in Europe and approximately 7% in Canada, with the remaining approximately 7% spread across various other countries. The Company’s business is organized and managed in two reporting segments: Fire Safety and Specialty Products. The Fire Safety Segment is a formulator and manufacturer of fire management products that help the Company’s customers combat various types of fires, including wildland, industrial structural, flammable liquids and other types of fires. The Fire Safety Segment also offers specialized equipment and services, typically in conjunction with our fire management products to support the Company’s customers’ firefighting operations. The Company’s specialized equipment includes airbase retardant storage, mixing, and delivery equipment; mobile retardant bases; retardant ground application units; mobile foam equipment; and equipment that the Company custom designs and manufactures to meet specific customer needs. The Specialty Products Segment develops, produces and markets products for non-fire safety markets. The Specialty Products Segment includes Phosphorus Derivatives, Inc., which produces Phosphorus Pentasulfide (“P 2 S 5 ”) based lubricant additives. P 2 S 5 is also used in pesticide and mining chemicals applications, and emerging electric battery technologies. The Specialty Products Segment also includes Intelligent Manufacturing Solutions (“IMS”), which is a manufacturer of electronic or electro-mechanical components of larger solutions. IMS has a flexible, vertically integrated production facility that allows it to acquire and produce a variety of product lines across a range of end markets, including communications infrastructure, energy infrastructure, defense systems, and industrial systems, with a substantial focus on aftermarket repair and replacement. The Company completed the acquisition of MMT in January 2026, and the Company expects that MMT will be part of its Specialty Products Segment. MMT provides highly engineered machinery and associated aftermarket consumables, parts, and services to support the production of complex medical devices as well as select highly engineered industrial and aerospace and defense use cases. MMT’s capabilities include original equipment manufacturing, including application specific equipment and automation solutions for medical devices such as complex catheters, guidewires and microcoils, as well as aftermarket parts, services, and consumables.
