Polar Power

What Polar Power does

Polar Power Inc. (NASDAQ: POLA) is a Gardena, California-based designer, manufacturer, and assembler of direct current (DC) power generation systems founded in 1979. The company sells DC generators ranging from 5 kW to 27 kW in diesel, LPG/propane/natural gas, and marine configurations, alongside proprietary 6200 and 8000 Series permanent magnet hybrid homopolar alternators developed in-house since 1992. Its integrated product ecosystem also covers hybrid solar-diesel power systems, lithium-ion battery systems, supercapacitors, and digital control software (MCS 2020 and CMCS), with all units custom-assembled in the Los Angeles area to meet application-specific requirements.

The company serves primary end markets in telecommunications (including AT&T for cell tower backup power) and the U.S. military (Army, Navy, Air Force, Defense Logistics Agency, including U-2 program GPU applications), with secondary verticals in marine, renewable energy, rapid EV charging, microgrid/UPS, and oil fields. Products are sold in over 100 countries via a direct enterprise field-sales model led by regional directors in North America, Latin America/Caribbean, and Asia Pacific, with quote-based pricing and no standard published price lists.

Financially, Polar Power is a micro-cap public company (11-50 employees) currently in a turnaround phase: Q3 2025 sales fell 74% year-over-year driving a $4.08M net loss and inventory write-downs, while Q1 2026 net loss narrowed 86% YoY to $176K with gross margin recovering to 65.7% from 18.6%. The company is operating under a restructuring engagement with Mammoth Crest Capital, financed in part by $970,600 of convertible notes placed in May 2026, with management targeting Nasdaq listing compliance recovery and diversification into microgrids, EV charging, and international markets.
