Overview

We design, manufacture, and sell DC power generators, renewable energy and cooling systems for applications primarily in the telecommunications market and, to a lesser extent, in other markets, including military, electric vehicle charging, marine and industrial. We are continuously diversifying our customer base and are selling our products into non-telecommunication markets and applications at an increasing rate.

Within the various markets we service, our DC power systems provide reliable and low-cost DC power to service applications that do not have access to the utility grid (i.e., prime power applications) or have critical power needs and cannot be without power in the event of utility grid failure (i.e., back-up power applications).

Serving these various markets, we offer the following three configurations of our DC power systems, with output power ranging from 5 kW to 50 kW:

Our DC power systems are available in diesel, natural gas, LPG / propane and renewable formats, with diesel, natural gas and propane gas being the predominate formats.

During the years ended December 31, 2024 and 2023, 88% and 95%, respectively, of our total net sales were within the telecommunications market. In 2024, our two largest customers represented 48% and 14% of our total net sales, respectively, one being a Tier-1 telecommunications customer in the U.S. and one being a telecommunications customer outside the U.S. In 2023, our two largest customers represented 50% and 18% of our total net sales, respectively, one being a Tier-1 telecommunications customer in the U.S. and one being a telecommunications customer outside the U.S. There was no other revenue from customers in excess of 10% of total net sales in either period. During those periods, the majority of our sales were of our DC base powers systems. During 2024 and 2023, sales to international customers accounted for 13% and 21% of total revenue, respectively. Sales to military customers during 2024 and 2023 accounted for 8% and 3% of total revenues, respectively. During 2024 and 2023, sales to the marine and other markets accounted for 4% and 2% of total revenue, respectively.

We launched our prime power DC generators incorporating the Toyota 1KS engines optimized for propane, natural gas, and extremely long operational life. We believe that with the increasing installation restrictions on small diesel engines along with their limited availability due to stringent EPA regulations will force a change to natural gas and propane (LPG) generators. LPG and natural gas are lower in cost than diesel fuel in many areas throughout the world. Our new LPG and natural gas generators will provide strong opportunities for growth and diversification in line with our long-term plan.

At the international level, we have several telecommunications customers in the south pacific region purchasing our DC generators to develop the telecommunications infrastructure in this region. We believe the implementation and ongoing development of 5G networks along with programs to develop the telecommunications infrastructure in rural and underdeveloped countries will continue to fuel our growth in the telecommunications market over the next five to ten years.

In May 2023, we announced plans to expand our mobile offerings by upgrading our mobile CHAdeMO EV chargers to the universal combined charging system standard to reach the mobile EV charging market. Mobile EV chargers are used for emergency roadside service providing a fast-charging solution for EVs that have run out of charge before reaching a stationary charging facility. During second half of 2024, we have successfully tested our demonstrator model on several platforms and made appropriate improvements and changes. We believe this configuration of remote mobile electric vehicle charger is just an initial model and based on power and fuel needs will result in various additional configurations.

We also continue to market our DC generators for the military, advanced mobility and marine markets as part of our ongoing customer diversification strategy. The military’s increasing use of robotics, drones, and computerization in the field is driving the demand for battery charging with DC generators. Military sales are advantageous because of their long-term contracts and they tend to cover the cost of product development.

We expect that opportunities in the bad-grid (i.e., areas where wireless towers are connected to an electrical grid that loses power for more than eight hours), and off-grid (i.e., areas where wireless towers are not connected to an electrical grid) applications, which include telecommunications towers, commercial and residential backup power, electric vehicle charging, “mini-grid” and various other power applications, will help to expand the market for our natural gas/LPG (propane) product lines domestically and internationally. In 2024, we demonstrated a microgrid product that can provide ²⁴⁄₇ electric power to a commercial facility. This project was funded by UNHCR, a United Nations organization. The product included DC generator, battery storage, AC inverter, solar charge controller and remote monitoring in a single container which can be delivered to any remote location to provide power. We believe this product in its current configuration can serve mid-level micro grid needs in residential and commercial areas. We plan to develop new configurations of DC power system, battery storage and solar products to optimize the match between our solutions and various application needs.

Critical Accounting Policies

We believe that the following critical accounting policies, among others, affect our more significant judgment and estimates used in the preparation of our financial statements:

Revenue Recognition: We recognize revenue in accordance with Financial Accounting Standards Board Accounting Standards Codification 606, “Revenue from Contracts with Customers” (ASC 606). ASC 606 requires entities to recognize revenue through the application of a five-step model, which includes: identification of the contract; identification of the performance obligations; determination of the transaction price; allocation of the transaction price to the performance obligations; and recognition of revenue as the entity satisfies the performance obligations.

Substantially all of our revenue is derived from product sales. Product revenue is recognized when performance obligations under the terms of a contract are satisfied, which occurs for us upon shipment or delivery of products or services to our customers based on written sales terms, which is also when control is transferred. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring the products or services to a customer. We determine whether delivery has occurred based on when title transfers and the risks and rewards of ownership have transferred to the customer, which usually occurs when we place the product with the customer’s carrier or deliver the product to a customer’s location. We regularly review our customers’ financial positions to ensure that collectability is reasonably assured.

We also recognize revenue from the rental of equipment. Our rental revenues have not been significant to date and have accounted for less than one percent of total revenues for the years ended December 31, 2024 and 2023.

Warranty Costs: We provide limited warranties for parts and labor at no cost to our customers within a specified time period after the sale. Our standard warranty on new products is two years from the date of delivery to the customer. We offer a limited extended warranty of up to five years on our certified DC power systems based on application and usage. Our warranties are of an assurance-type and come standard with all of our products to cover repair or replacement should product not perform as expected. Provisions for estimated expenses related to product warranties are made at the time products are sold. These estimates are established using historical information about the nature, frequency and average cost of warranty claim settlements as well as product manufacturing and recovery from suppliers.

Inventory: Inventories are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out (FIFO) basis. We record adjustments to our inventory based on an estimated forecast of the inventory demand, taking into consideration, among others, inventory turnover, inventory quantities on hand, unfilled customer order quantities, forecasted demand, current prices, competitive pricing, and trends and performance of similar products.

Effects of Inflation

The impact of inflation and changing prices during 2024 has not been significant on the financial condition or results of operations of our company. Rapid changes in the global economy may cause significant spikes in inflation which may have an impact in our financial condition during 2025 and beyond. Because some of our contracts are at a fixed price, we face the risk that cost overruns or inflation may exceed, erode or eliminate our expected profit margin, or cause us to record a loss on certain projects. We are taking actions to manage the potential impacts of these matters and we will continue to assess the actual and expected impacts and the need for further action.

Financial Performance Summary – Year Ended December 31, 2024

Our net sales for the year ended December 31, 2024, were $13,970, as compared to $15,293 for the year ended December 31, 2023. We reported a net loss of $4,677 for 2024, as compared to net loss of $6,548 for 2023. Cost of sales includes inventory write-downs of $900 in 2024, and $450 in 2023, to adjust inventory to net realizable value.

During 2024, we saw significant volatility in revenue primarily from our largest customer which greatly affected overall performance. We believe the drop in sales is attributed to excess inventory at customer warehouse collected during COVID-19 and customer concerted effort to reduce inventory. We believe the excess inventory has largely been reduced and anticipate normalization in purchases during second half of 2025. We reached profitability in the second and third quarters of the year with gross margins at 39% and 29%, respectively. We experienced net losses and negative margins in the first and fourth quarter. We believe economic and geopolitical factors continue to influence our customers’ buying patterns.

During 2024, sales to our customers in the U.S. were $12,108, or 87% of total net sales, as compared to 79% in 2023. During 2024, our largest customer represented 48% of our total net sales, as compared to 50% in 2023. Our international sales were $1,862, or 13% of total net sales in 2024, as compared to $3,216, or 21%, during 2023.

Our sales backlog as of December 31, 2024, was $1,306, with 53% of that amount being attributable to our largest U.S. telecommunications customer, 3% attributed to other telecommunications customers, 36% to customers in the military markets, and 9% to customers in marine and other markets. The Company expects to complete shipment of these orders within the next six to twelve months.

We plan to continue to market our products globally and expand our customer base in all market segments. We plan to continually improve our inventory turns to generate cash flow from operations combined with austerity measures on non-essentials overhead to manage cash flow while sales improves. During 2024, we successfully reduced overhead expenses by $996 to improve cash generated through operations. We plan to continue take proactive steps to manage our operations and mitigate the financial impacts of higher costs, supply chain issues, and geopolitical factors. We have $12.9 million in inventory and completed updating our manufacturing facilities to accommodate three to four times the annual revenue of 2024. However, the full impact on our financial and operating performance of these factors will depend significantly on the duration and severity of these factors, the actions taken to mitigate their impact, disruption to our supply chain, and the pace with which our clients return to more normalized purchasing behavior, among others factors beyond our knowledge or control.

Results of Operations

The tables presented below, which compare our results of operations from one period to another, present the results for each period, the change in those results from one period to another in both dollars and percentage change, and the results for each period as a percentage of net revenues.

Net Sales: Net sales decreased by $1,323, or 9%, to $13,970 for the year ended December 31, 2024, as compared to $15,293 for the year ended December 31, 2023. The decrease in net sales is primarily due to a decrease in deliveries of our DC power generators to our largest telecommunications customer in the U.S.

During 2024, revenue from telecommunications customers accounted for 88% of total net sales, as compared to 95% of total net sales during 2023. Our two largest customers represented 48% and 14% of our total net sales in 2024, as compared to 50% and 18% in 2023. Our largest customer in each year was a Tier-1 telecommunications customer in the U.S., and our second largest customer in each year was a telecommunications customer outside the U.S. There was no other revenue from customers in excess of 10% of total net sales in either period.

During 2024 and 2023, sales to international customers accounted for 13% and 21% of total revenue, respectively. Sales to military customers during 2024 and 2023 accounted for 8% and 3% of total revenues, respectively. Sales to marine and other markets during 2024 and 2023 accounted for 4% and 2% of total revenue, respectively. Most of our sales were of our DC base powers systems during the two years.

Cost of Sales: Cost of sales decreased by $1,942 or 13%, to $12,656 during 2024, compared to $14,598 during 2023. Cost of sales as a percentage of net sales decreased from 95.5% in 2023 to 90.6% in 2024 primarily as a result of a decrease in factory overhead absorption as compared to the same period in 2023. We believe we can achieve significant reductions in the cost of sales in 2025 as a percentage of net sales as volumes in production increase. Cost of sales includes inventory write-downs of $900 in 2024, and $450 in 2023, to adjust inventory to net realizable value.

Gross Profit: We recognized a gross profit of $1,314 during 2024, as compared to a gross profit of $695 during 2023, which represents an increase in gross profit of $619 or 89%. Gross profit as a percentage of net sales increased to 9.4% in 2024, as compared to 4.5% in 2023. The increase in gross profit during 2024 was primarily because of improved labor efficiencies in manufacturing resulting from higher production volumes primarily during the second and third quarters of 2024.

Sales and Marketing Expenses: Sales and marketing expenses decreased $162 to $1,010 during 2024, as compared to $1,172 during 2023. The decrease was attributable to a slight decrease in sales support staff during 2024 as compared the same period in 2023. We plan to increase our sales force and increase our marketing and tradeshow activities in 2025 to support our diversification strategy and expand our customer base in all market segments.

Research and Development Expenses: During 2024, research and development expenses decreased by $451 to $771,
