Acorn Energy, Inc. is a holding company focused on technology driven solutions for energy infrastructure asset management. The company conducts its operations primarily through the OmniMetrix subsidiary which provides wireless remote monitoring and control systems and Internet of Things applications for power generation and cathodic protection markets. As of December 31, 2025 the firm employed 27 individuals all located in the United States. Acorn Energy, Inc. emphasizes research and development to improve its proprietary OCOM communications platform and to broaden its product offerings.

Acorn Energy, Inc. generates revenue principally from the sale of monitoring devices and from associated service and support contracts. In the Power Generation segment revenue is derived from the OmniPro commercial monitor, the Omni residential monitor, the Smart Annunciator for visual generator status, and the legacy TrueGuard product line, together with ongoing monitoring and data services. In the Cathodic Protection segment revenue comes from the Hero 2 Rectifier Monitor, the Patriot Plus Test Station Monitor, the RAD and RADex product families that monitor rectifiers test stations and solid state decouplers and enable remote control of AC mitigation tools, plus related service agreements. The company also expects future revenue from its strategic technology partnership with AIO Systems Ltd which adds cloud based monitoring and analytics solutions for cell towers data centers and utility assets in North America.

The company operates through the following segments: Power Generation and Cathodic Protection.

• Power Generation: Provides wireless remote monitoring and control systems and IoT applications for commercial industrial and residential power generation equipment, including the Omni family of products built on the OCOM platform launched in 2025, the Smart Annunciator for visual generator status, and the legacy TrueGuard line. This segment collects operational data from generator control panels to enable diagnostic analysis and prognostic capabilities that help customers avoid failures and reduce maintenance costs.

• Cathodic Protection: Provides remote monitoring and control products for cathodic protection systems on gas pipelines, including the Hero 2 Rectifier Monitor that monitors and controls rectifiers, the Patriot Plus Test Station Monitor that supplies data points along pipeline segments including AC current density, and the RAD and RADex product families that mount onto solid state decouplers to enable remote disconnect or connect of AC mitigation tools, with the RADex model launched in 2025 on the OCOM platform adding cathodic measurement capabilities. This segment helps pipeline operators reduce corrosion and improve safety by continuously monitoring protection levels.

Acorn Energy, Inc. maintains a strong competitive position in the high performance power generation monitoring market due to its early entry as a first provider of wireless remote monitoring systems, its proprietary OCOM communications platform, and its ability to monitor equipment from all major generator brands. Competitors in this space include independent monitoring firms such as Ayantra, FleetZOOM, Gen-Tracker, and PowerTelematics, as well as original equipment manufacturers that offer brand specific solutions. In the cathodic protection market the company faces rivals like Mobiltex Solutions, Abriox, Elecsys, and American Innovations but believes its integrated monitoring and control approach delivers greater functionality than many of these alternatives.

Acorn Energy, Inc. serves a varied customer base that includes cell tower operators, manufacturing plants, medical facilities, data centers, retail stores, public transportation systems, energy distribution companies, federal state and municipal government facilities, and residential backup generator owners. The company also collaborates with original equipment manufacturers such as Caterpillar, Kohler, Generac, Cummins, Briggs and Stratton, and MTU Solutions to integrate its monitoring solutions across diverse equipment types. Through its partnership with AIO Systems Ltd the firm aims to reach additional customers in the cell tower data center and utility sectors.
