Polar Power supplies telecommunications sites with equipment that keeps them powered during grid outages or where reliable grid power is unavailable. Its generators deliver direct current to tower equipment and charge batteries; hybrid versions add battery storage and, in some cases, solar panels. Most sales come from generator-based systems rather than hybrids. The company sells directly to telecommunications providers, with parts and supporting services contributing a smaller share of revenue. It also serves smaller markets such as military applications.
Telecommunications accounts for the great majority of sales, and one large U.S. telecommunications customer supplies most of the company's revenue. Customers generally place individual purchase orders rather than make firm, long-term volume commitments, so the business depends heavily on winning new orders and on the timing of customer deployments.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
Polar Power depends on concentrated telecom orders and reliable engine deliveries, especially from unlisted Yanmar, which supplied 70% of the engines sold in its systems in 2025.
AT&T is a significant customer paying Polar Power for telecom power systems, so losing its orders would matter to Polar; AT&T itself earns revenue by providing wireless and wired services to consumers and businesses. Payments also matter: Polar's lending terms allow eligible AT&T bills to remain unpaid for up to 120 days, versus 90 days for other customers, when borrowing against customer receivables.
Verizon Communications' Verizon Wireless is a significant buyer of Polar Power's equipment to keep its wireless network powered, making those orders important to Polar. Verizon sells communications services to consumers and businesses; its purchases of network backup-power equipment are the part to watch for Polar, rather than its overall service revenue.
Generac Holdings competes for telecom operators' backup-power purchases with AC generators, while Polar Power sells DC generators. Generac also sells power equipment to homes and other business markets, so its telecom generator business is the relevant part to watch for competitive pressure on Polar.
EnerSys and Polar Power both depend on telecom operators spending to keep networks powered: EnerSys sells energy-storage and power systems, while Polar sells generators. Watch telecom demand within EnerSys' Energy Systems business, rather than its batteries for industrial vehicles, for a read on that shared spending.
Polar Power relies on Toyota Motor Corporation for natural-gas and propane engines used in its generators; Toyota supplied approximately 7% of the engines sold in Polar's DC power systems in 2025. Toyota mainly sells vehicles, but for Polar the relevant news is whether these engines arrive on time and at acceptable quality and cost, since supply problems can impair manufacturing.
AT&T Inc. earningsT
AT&T’s report offers a read on the wireless business and network investment of a significant Polar Power customer, both relevant to the foundation for its equipment demand.
Read wireless service revenue alongside network investment. If both hold up or grow, AT&T has a steadier business base for network spending, but that does not confirm an order from AT&T to Polar Power; if both weaken, AT&T may be more cautious with network outlays, raising the risk of delayed or reduced orders for Polar Power.
GENERAC HOLDINGS INC earningsGNRC
If Generac reports on its telecom backup-power business, its results can show whether its AC generators are competing for the same operator purchases as Polar Power’s DC systems.
Focus on any telecom-related backup-power demand Generac reports, not growth in its home-generator business. Strong telecom demand accompanied by signs that operators are choosing AC generators would point to more direct competition for Polar Power; weak demand in that area would give less reason to conclude that Generac is taking business from it.
Fed Interest Rate Decision
For Polar Power, the Fed’s policy rate—the rate that guides borrowing costs across the economy—can affect interest paid on advances under its $4.036 million Pinnacle facility, priced in 2025 at 8% on receivables and 9% on inventory advances.

If it comes in above expectations
If the policy rate is above expectations, higher economy-wide borrowing costs may raise interest on Polar Power’s advances if their rates reprice, leaving less cash for operations and debt repayment.
If it comes in below expectations
If the policy rate is below expectations, lower economy-wide borrowing costs may reduce interest on Polar Power’s advances if their rates reprice, leaving more cash for operations and debt repayment.
EnerSys, Inc. earningsENS
Telecom demand within EnerSys’ Energy Systems business can show whether operators’ spending to power their networks is supporting the broader market Polar Power serves.
Look for telecom-related demand within EnerSys’ Energy Systems business, not its industrial-vehicle battery business. If telecom demand holds up or grows, operators are still spending to power their networks, supporting a broader market for Polar Power’s generators; if it falls, the industry spending available to Polar Power may be shrinking, though this does not establish whether Polar Power’s own orders rose or fell.
Polar Power, Inc. earningsThis company
Polar Power’s report will show whether recovering sales of its DC power systems can cover production costs and factory overhead.
Read system sales alongside gross profit—the amount left after production costs—and check for inventory write-downs. Rising sales with positive gross profit and no large write-downs would point to better factory use and stronger product economics; weak sales with another gross loss or large write-downs would show that underused production and inventory problems are still eating into revenue.
