Arthur Sams, Chairman and CEO of Polar Power, commented, “We continue to improve our operational efficiency and increase sales in aftermarket parts and service, which provide higher margins, as we expand our customer base. During the first quarter, we received orders and shipped products to first time customers who are in process of evaluating and integrating our products into their operations. Our focus on addressing aftermarket parts and service on a large equipment fleet has resulted in sales of aftermarket parts and services representing 28% of our total net sales in the first quarter of 2025. During this quarter, we jointly worked with our telecom customer to implement monitoring equipment on legacy units to report performance and maintenance data, which we believe improves product uptime and longevity. We plan to jointly implement this remote monitoring system on over five thousand legacy units during the next twelve months, which we expect to generate additional aftermarket parts and service revenue. During the first quarter of 2025, sales to our telecom customers represented 82% of total net sales, compared to 71% in the same period in 2024. Sales to international markets represented 18% of total net sales in the first quarter of 2025, compared to 6% in the same period in 2024. Sales to military customers represented 17% of total net sales in the first quarter of 2025, compared to 26% in the same period in 2024.”

“We have seen a steady decline in excess inventory at our largest customer which was reflected by higher bookings towards the end of the first quarter. During the first quarter, we have seen benefits of implementation of companywide ERP systems which helped streamlined manufacturing operations, thereby improving our labor efficiencies and manufacturing lead times. During the forty years of our business, we have significant installed base of our equipment in the field, which are still being used by second or third-tier users. We are contacting these users to promote product upgrades, repairs or new equipment sales opportunities. Currently, we have approximately $13 million of raw materials in inventory which helps reduce our cash burn for the rest of the year. We have also made substantial improvements to our manufacturing capacity in recent years, giving us the potential to produce products of more than $50 million in revenue per year, assuming sufficient bookings are in place,” concluded Mr. Sams.
