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, 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. The changes in customer diversity are reported in the financial section.

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 and mobile applications) or have critical power needs and cannot be without power in the event of utility grid failure (i.e., back-up power applications).

We believe it’s more efficient to build power systems around the DC generator because it’s simpler to integrate with battery storage and solar photovoltaics which also operate on DC. Many applications in communications, water pumping, lighting, vehicle and vessel propulsion, security systems operate on DC power only. Many micro-grids and energy storage are DC based and use inverters to convert the DC to AC.

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

Base power systems. These stationary systems integrate a DC generator and automated controls with remote monitoring, which are typically contained within an environmentally regulated enclosure.
Hybrid power systems. These systems incorporate lithium-ion batteries (or other advanced battery chemistries) with our proprietary battery management system into our standard DC power systems.
DC solar hybrid power systems. These stationary systems incorporate photovoltaic and other sources of renewable energy into our DC hybrid power systems.
Mobile power systems. These are very light weight and compact power systems used for EV charging, robotics, communications, security.

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

We were incorporated in 1979 in the State of Washington as Polar Products, Inc., and in 1991 we reincorporated in the State of California under the name Polar Power, Inc. In December 2016, Polar Power, Inc. reincorporated in the State of Delaware. Our internet website address is https://polarpower.com/.

Recent Developments

On November 24, 2023, the Company received a deficiency letter from the Listing Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) indicating that the Company’s common stock is subject to potential delisting from the Nasdaq because for a period of 30 consecutive business days, the bid price of the Company’s common stock has closed below the minimum $1.00 per share requirement for continued inclusion under Nasdaq Marketplace Rule 5550(a)(2) (the “Bid Price Rule”). The Nasdaq deficiency letter has no immediate effect on the listing of the Company’s common stock, and its common stock continues to trade on The Nasdaq Capital Market under the symbol “POLA” at this time. The Nasdaq notice indicated that, in accordance with Nasdaq Marketplace Rule 5810(c)(3)(A), the Company will be provided 180 calendar days, or until May 22, 2024, to regain compliance.

In the event that the Company receives notice that its common stock is being delisted, the Nasdaq listing rules permit the Company to appeal a delisting determination by Nasdaq to a hearings panel.

On November 30, 2023, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with ThinkEquity LLC, as the representative (the “Representative”) of the several underwriters named therein (collectively, the “Underwriters”), pursuant to which the Company sold to the Underwriters an aggregate of 4,000,000 shares (the “Shares”) of the Company’s common stock, $0.0001 par value per share, at a price to the public of $0.40 per share, in a firm commitment underwritten public offering (the “Offering”). The Company also granted the Underwriters an option exercisable for 45 days from the date of the Underwriting Agreement to purchase up to an additional 600,000 shares of common stock (or pre-funded warrants in lieu thereof) solely for the purpose of covering over-allotments. The Representative exercised the over-allotment option in full on December 4, 2023, to purchase an additional 600,000 shares of common stock (the “Over-Allotment Exercise’). The Offering and closing on the Over-Allotment Exercise closed concurrently on December 5, 2023. The Offering was made pursuant to an effective registration statement on Form S-3 (Registration No. 333-252196) and a related prospectus and prospectus supplement, in each case filed with the Securities and Exchange Commission.

On December 18, 2023, Peter Gross, a member of the Board of Directors of the Company, resigned as a member of the Board of Directors of the Company (the “Board”). Mr. Gross, an independent director, served as a member of the audit committee, chair of the compensation committee and chair of the nominating and corporate governance committee of the Board at the time of his resignation.

On January 5, 2024, the Company received a notification letter from Nasdaq that due to Mr. Gross’ resignation, the Company is no longer in compliance with Nasdaq Listing Rule 5605. Pursuant to Nasdaq Listing Rule 5605(c)(4), the Company is entitled to a cure period to regain compliance (i) until the earlier of the Company’s next annual shareholders’ meeting or December 18, 2024; or (ii) if the next annual shareholders’ meeting is held before June 17, 2024, then the Company must evidence compliance no later than June 17, 2024. The Company intends to appoint an additional independent director to the Board and the committees prior to the end of the cure periods.

Recent Business Events

The COVID-19 pandemic, inflation, the impacts of war and other recent geopolitical events have negatively impacted business and industries all over the world. These events have had a significant negative impact on our overall operations including revenues, productivity, gross margins, and liquidity. They have resulted in labor shortages, disruptions in the chain of supply, and higher material costs. They also resulted in unexpected challenges related to customer product or delivery requirements.

During the second half of 2023, our largest telecommunications customer asked us to postpone deliveries towards the end of the year. As of December 31, 2023, approximately $2.0 million in DC power generators that were scheduled to ship in 2023 remained in our sales backlog. During 2022 and to a lesser extent in 2023, supply chain constraints affected timely delivery of raw materials required to complete our DC power systems. We believe that the aftermath of the pandemic, inflation, the impacts of war and other recent geopolitical events will be an ongoing challenge for years to come and to adapt will require us to further globalize our vendors, engineering, and customers.

We continue to focus on expanding our market share into international markets as part of our diversification strategy. During 2023 and 2022, sales to customers in international markets represented 21% and 25% of our total net sales, respectively, as compared to 8% and 17% in 2021 and 2020, respectively. During 2022, we received purchase orders totaling $6.2 million from a telecommunications customer in the South Pacific Islands for our DC power generators for off-grid applications. We completed shipping this order to the South Pacific in 2023. This order is part of a growing program to develop broadband services in the South Pacific region.

During 2023, 50% of our total net sales were derived from our largest customer, compared to 66% in 2022. During 2023, 3% of our total net sales were derived from customers in the military market, as compared to 1% in 2022. We believe military actions of the Russian Federation and its invasion of Ukraine and conflicts between Israel and Hamas have added considerable to our shipping costs due to diesel fuel costs. However, we believe the resulting geopolitical uncertainty should increase our military contracts.

The implementation of 5G networks by Tier-1 telecommunication customers in the U.S. has also resulted in a significant increase in orders of our DC power systems. Approximately 75% of our net sales during 2023 were of our DC power systems to support 5G networks and 60% of our sales backlog as of December 31, 2023 are purchase orders of our of DC power systems to support 5G networks in the U.S.

For the three-year period prior to the pandemic, we experienced high double-digit sales growth which resulted in us making strategic investments to increase our production capacity to $50 million annual revenue through an increase in plant space and the addition of automation equipment. The unanticipated drop in sales during in the first three years after the pandemic caused a disproportionate distribution of fixed and semi-fixed overhead costs across much lower revenues. During 2023, our largest customer asked us to postpone deliveries of our DC power generators to 2024 resulting in a decrease in revenue and higher overhead cost. These delays in shipments, amongst others we have experienced since the pandemic, along with our addition of inventory to mitigate parts shortages on long-lead items, have resulted in elevated inventory levels. As of December 31, 2023, we have $16.5 million in inventory. We believe this inventory and our investments in state-of the-art equipment, additions to manufacturing plant space, and employee training will yield improvements in our gross margins and liquidity as sales volumes increase and as the economy normalizes from the impact of the pandemic and other known and unknown factors affecting the global economy.

Going Concern

The Company’s financial statements have been prepared under the assumption that the Company will continue as a going concern. For the year ended December 31, 2023, the Company recorded a net loss of $6,548 and used cash in operations of $3,430. These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year of the date that the financial statements are issued. In addition, the Company’s independent registered public accounting firm, in their report on the Company’s December 31, 2023, audited financial statements, raised substantial doubt about the Company’s ability to continue as a going concern.

Our ability to continue as a going concern is dependent upon our ability to obtain additional financing, drive further operating efficiencies, reduce expenditures, and ultimately, create profitable operations Our ability to obtain additional financing in the debt and equity capital markets is subject to several factors, including market and economic conditions, our performance and investor sentiment with respect to us and our industry. The Company has taken action to improve its margins, and is continuing to build a strong back log, and expects to continue investing in product development and sales and marketing activities. In the event that the Company does not generate sufficient cash flows from operations and is unable to obtain funding, the Company will be forced to delay, reduce, or eliminate some or all of its discretionary spending, which could adversely affect the Company’s business prospects, ability to meet long-term liquidity needs or ability to continue operations.

Markets

We primarily operate within 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.

Telecommunications

We provide power generation equipment for the telecommunications markets. Our equipment provides backup power to grid connected mobile tower sites during power outages resulting from severe weather like hurricanes, wildfires, and floods. Most telecommunications towers are equipped with battery backup for short term power outages. Our DC power generators are installed to address longer-term disruptions in power. We also deliver products that provide prime power for off-grid telecommunications tower sites installed in remote and rural areas where reliability of the power grid is suspect. Since 2012, the telecommunications market is our largest market segment and has contributed over 87% of our annual revenues.

Since 2012, we developed products and configurations that target telecommunications applications with key features like high fuel efficiency, light weight and compact design when compared to our competitors’ products. These features allow our telecommunications customers to install equipment requiring a smaller footprint on building roof tops and compact commercial sites while also requiring less fuel storage due to the fuel efficiency of our products. In the past eight years, we have gained approval and certifications from four top Tier-1 telecommunications operators in the U.S. market. With over 90% of the world’s telecommunication towers located in non-U.S. territories, we decided to establish international sales offices in Poland, Romania, Australia, U.A.E., Dominican Republic and South Africa to provide long term growth. In 2017, we began investments into international markets and have recorded a steady increase in sales every year since.

In the U.S. market, over 95% of the telecommunications towers are connected to a power grid, thereby only requiring backup power generation in equipment in case of an emergency loss of power, while in the emerging markets of Africa and Asia, a significant percentage of telecommunications towers are not connected to the grid thereby requiring fuel-efficient prime power equipment to provide power by charging the batteries. Most prime power sites also require integration with solar and storage batteries to utilize renewable energy during the day while generators and batteries provide power during nights and/or on cloudy days. In the U.S., telecommunications companies have focused their efforts on adding generators to provide backup power at existing sites, while in the international market telecommunications companies are in expansion phase of adding new sites to the infrastructure to provide coverage in rural and remote areas.

The advent of 5G technology has resulted in a digital revolution within both the commercial and consumer sectors leading to an exponential increase in data usage. We believe that the need for backup power equipment in the telecommunications services industry which consists of digital infrastructure (e.g., fiber, telecommunications towers, active networks and data centers), operators (e.g., mobile and fixed broadband, data centers and cloud computing) and applications (e.g., broadband connections, telephones, video streaming and e-commerce), holds promising growth opportunities as 5G use expands in the near and long term.

Wireless network capabilities continue to expand far beyond smart phones and mobile devices. The 5G mobile network is converging connectivity, intelligent edge and Internet of Things (IoT) technologies resulting in an increase in telecommunications tower sites in both the U.S. and abroad. The 5G network delivers broadband-like services such as high-definition streaming video to a cell phone. Businesses benefit from using 5G for data monitoring and cloud-native 5G networks to compute and store data locally. All of these applications dramatically scale up data usage which requires an increase in infrastructure and an increase in power and backup generators.

The pervasiveness of 5G, including reliance by users on, among other things, local weather, traffic conditions, self-driving vehicles, wearable health monitoring devices that automatically informs doctors, stores automatically ordering items sold on virtual carts, farmers automated irrigation system with tracking sensors, will require robust backup equipment at telecommunications sites. We believe higher data usage will require higher reliability backup systems that are fuel efficient and are located in proximity to the point of use. In urban environments, roof-top space, weight of the equipment and the amount of fuel storage are critical factors in the selection of backup equipment. As one of the leading providers of DC power generation equipment, we have demonstrated these benefits to telecommunications providers for decades and we are therefore encouraged with the prospect of infrastructure expansion in this space that requires fuel efficient and lower emission power generation equipment.

Military

Since 1979, we have been developing and marketing products to the U.S. military and large defense contractors in the U.S. and international markets. The need for light weight and compact DC power generation systems are vital for military operations and commonly used to charge storage batteries, provide backup emergency power, or provide startup power for aircrafts or weapon systems. During the past decade, digitization of the military accelerated exponentially to support modern information, communication, and weapon systems. The need to process information rapidly has led to digitization of command, control, communications, computers and intelligence across both combat support and service support. This expansion in data transfer and storage has led to an increase in energy needs, which requires efficient power generation equipment that can charge batteries or directly power these systems.

A digitized battlefield includes sensors, information processing, data distribution, electronic countermeasures, all requiring with few exceptions, DC power. Our DC generators designed for military applications provide:

enhanced mobility, reliability and maintainability;
improved fuel efficiency;
reduced system size and weight;
reduced infrared and acoustic signatures;
increased survivability in rugged combat operations; and
reduced total cost of ownership.

In 2016, the military began the Advanced Medium Mobile Power Sources, or AMMPS, a U.S. Department of Defense program to develop and deliver 5 kW-50 kW output ranging generators in either a skid, trailer mounted, or microgrid configurations to replace legacy standalone AC generators. The new generation of mobile power generators combined with solar and wind power can function as sustainable sources of DC and AC power in remote areas. The new generation of AMMPS power systems are required to provide 21% higher fuel efficiency, lower noise, weight, 90% reliability and be capable of performing in extreme environments. During 2020, we directly and jointly partnered with defense contractors, provided DC hybrid power systems, with integrated controls providing higher fuel efficiency than legacy AC generators currently in use.

Improvements in sensors, navigation and communication technologies have led to increased integration of situational awareness systems that allow all combat assets to communicate and coordinate both defensive and offensive efforts during combat. In earlier combat vehicle designs, these surveillance systems were powered by the main auxiliary vehicle battery, which required the vehicle’s main engine to continue operating to power auxiliary battery systems. A decade ago, we began delivering compact 3 kW – 15 kW DC power systems for communication and reconnaissance systems thereby improving fuel efficiency of the combat and vehicles when deployed. During the decade we have delivered several configurations of these auxiliary power units to the military, which vary in function from battery charging to supplying power to weapon systems.

We are currently in the process of development of next-generation higher output power DC power system. After conclusion of the testing of this higher power DC power system, we plan to introduce a configuration of this product to the residential and commercial microgrid market in emerging markets. We believe 50 kW standalone DC power system, powered by natural gas or LPG would be ideal for rural communities in emerging markets such as Africa and Asia. The capacity of 50 kW is sufficiently large enough to power a small rural hospital, dairy farm and a cluster of houses in a small village. The ease of connecting our DC power system with solar, battery packs or any other source of energy like wind can introduce a sustainable cost-effective solution in emerging markets.

The 50 kW generator can also provide roadside emergency charging services for electric vehicles.

Electric Vehicle Charging

According to Precedence Research, a market research company, the global electric vehicle market size accounted for USD 255.54 billion in 2023 and is expected to reach USD 2,108.80 billion by 2033, growing at a compound annual growth rate (CAGR) of 23.4% during the forecast period 2024 to 2033. The primary growth factors driven by significant number of government incentives such as tax rebates, subsidies, and grants. This increase will require a significant increase in charging stations globally to support the cumulative growth of electric vehicles. During 2023, the global electric vehicle charging station market size reached USD 34.59 billion and has a forecasted CAGR of 29.1% for the period of 2023 to 2032.

A 2018 article by McKinsey & Company entitled “The potential impact of electric vehicles on global energy systems” stated that although a modest increase in electric vehicle sales of 5% will not lead to a shortage in electricity since most new capacity can be delivered by renewables like solar, wind, and gas-powered generation. This modest increase in sales may have a significant impact on peak loads, especially in concentration points of electric vehicle charging and during the evening peak times when most electric vehicle users connect their vehicles for charging. The report claims unmanaged peak load increases due to electric vehicle charging will require increases in costly sub-station upgrades. We believe that the more cost-effective option will be investing into battery storage at the utility level to manage the peak loads or flexible electricity costs for electric vehicle charging to discourage peak load charging.

Regardless of how the peak charging issue is resolved, most homes have not been designed to allow for fast charging of electric vehicles. In order to address this issue, we are in the process of upgrading our CHAdeMO chargers to CCS natural gas-powered electric vehicle charger and combined heat and power generators. Our electric vehicle chargers, being independent of the grid, are designed to fast charge connected electric vehicles at home while providing backup power during power outages. In addition, the heat generated while charging is captured and delivered to heat the home, heat water for laundry, or heat the pool.

Our CHAdeMO style electric vehicle charger was initially designed in 2009 as a diesel-fueled mobile charger for EV manufacturers to aid in testing their vehicles in the field. We have supplied these mobile chargers to five of the leading automakers in the USA. We are presently improving this product using heavy duty 60,000-hour Toyota natural gas or propane engine. This product targets residential customers that own or are expected to own electric vehicles.

With the anticipated stress on utility grids due to an increase in the number of electric vehicles that require charging, combined with the fact that most homes are unable to provide fast charging, we believe that an independent natural gas-powered electric vehicle charger would be ideal and cost effective. Currently, many electric vehicle owners exceed the base power usage at home resulting in peak hour usage penalties which diminishes anticipated cost savings of using electric vehicles. Our residential natural gas-powered EV charger eliminates these costs while also providing backup power in case of emergencies.

The benefits of fast charging with a natural gas generator, as opposed to using the electric grid, includes avoids peak rate charges, a reduced carbon footprint and the opportunity to provide heating and air conditioning, through combined heat and power or CHP systems that utilize waste heat from the generator/charger which we believe is a compelling market opportunity for our new product.

Residential and Commercial Power – Mini-Grid

Increased use of electricity worldwide is directly related to humanity’s improvement in the quality of life. Increased global urbanization has resulted in many governments investing in power plants and providing infrastructure to satisfy the growing demand for electricity. Similar needs of the rural populations have been largely ignored worldwide due to the isolation, low density and population spread over vast areas resulting in an increased cost of infrastructure. Even in rural areas where the infrastructure was built to deliver electricity, frequent blackout and infrastructure failures are commonplace and often not repaired for long periods.

According to recent World Bank data, approximately 733 million, 9%, of the world’s population still lack electricity compared to 25% in 1994. While 42% of the world’s population still lives in rural areas, about 12% of those living in rural areas lack electricity. Approximately 69% of the population living without electricity are in sub-Saharan Africa while approximately 29% are located in South Asia and 2% in other areas.

During the past decade, developments in renewable energy and battery storage have provided an alternate method to resolve this energy inequity between rural and urban populations worldwide. However, due to weather and costs of such systems and technologies are still at an early stage of mass adoption. We envision a hybrid system with natural gas or LPG integrated with a solar and battery system to generate power during peaks and valleys of demand that we believe would be more cost effective and reliable than the current systems in place. These “Mini-Grid” hybrid systems would generate between 5kW – 25kW of power on 24/7 basis and provide electricity for a small housing unit, commercial facility or a school building.

Our Mini-Grid system uses natural gas or LPG as primary fuel source, the same fuel as cooking fuel in rural and remote regions worldwide. For decades, many governments have been allocating resources to eliminate solid fuels like wood, solid waste as cooking fuels from rural and remote communities. Significant progress has been made by providing economic subsidies for use of natural gas or LPG as cooking fuel to reduce pollution. In 2017, we established sales offices near the emerging growth countries of Australia and U.A.E. setup to develop strategic alliances with distributors to promote our residential solutions to communities living in bad-grid and off-grid areas.

Our Competitive Strengths

We have over a 40-year history and have developed a reputation as a proven supplier of reliable and advanced proprietary technology products to customers within the telecommunications, military, commercial, industrial and marine markets. We have invested significant capital and engineering expertise to develop power generation systems that are environmentally friendly and fuel-efficient. We further believe our success will be based on the following key competitive strengths:

Proprietary Technologies. Our decades of research and development has led to the development of DC power systems with output ranging from 5 kW – 50 kW. Our DC power systems integrates our proprietary DC alternator with electronic controls to monitor and control the power being outputted to the equipment, which is then coupled to an engine assembly and cooling systems. Our DC power system output voltage can be configured between 12 V – 800 VDC to match the precise application needs (e.g., telecom equipment, robotic propulsion drives, electric drives for marine vessels, electric vehicle chargers, etc.). Over the past decades we have developed proprietary charge algorithms for most commercially available batteries and match charge algorithms to battery model or chemistry prior to initiating a charge cycle. Unlike AC power systems, our DC power systems are directly connected to the battery source and therefore optimized for efficiently and safely charging a particular battery chemistry. AC power systems are indirectly connected to commercially available battery chargers that convert the AC output to DC voltage making it less efficient, higher in cost, and require considerably more space.
Engineering Expertise. Over the past four decades we have strategically constructed a product portfolio that focuses on improving energy efficiency by developing DC power output-based equipment where all major components and technologies are developed in-house, and proprietary manufacturing processes created in-house to ensure product reliability and long life. Our leading competitors approached the need for DC equipment in the telecom, military, and industrial markets by modifying legacy AC generators with conversion equipment resulting in significantly lower efficiency when compared to DC power systems. Being one of the first companies to develop DC generators for telecommunications, we developed proprietary components ranging from alternators, control systems and charging algorithms for various battery chemistries. We have focused on providing the lowest cost of ownership with demonstrated long life of our equipment during the past thirty years. Lowest cost of ownership is complemented with the best fuel economy, best in class weather resistance provided by aluminum enclosures and customized algorithms matching battery chemistries and operational profiles.
Manufacturing Competitiveness. We believe that our vertical integration approach to manufacturing lowers our production costs and improves our overall operational efficiency. In addition, vertically integrated manufacturing of our proprietary technologies such as DC alternators, charge controls and battery management systems, provides us with a greater control and protection over our intellectual property. We believe our modular approach to manufacturing provides us with the lowest manufacturing costs for our proprietary technologies while giving us the ability to deliver customized solutions to our Tier-1 wireless telecommunications customers.
Strong Customer Base. Our customer base consists of large telecommunications companies, military sub-contractors and industrial companies. Tier-1 telecommunications customers have represented 62% to 91% of our aggregated sales for the past five years. Initial demand of our products by telecommunications customers was primarily based on the need to provide backup power during electricity outages and for off grid remote locations. While our competitors provided and continue to provide legacy AC generators with DC conversion devices, we elected to invest significant time and capital in the research and development of products with a lowest cost of ownership. Certification of our products by Tier-1 telecommunications customers was time intensive and takes upwards of three years of field trials to receive final product acceptance. This thorough approach to vendor selection reduces the number of vendors selected by our telecommunications customers and has dramatically reduced the number of competitors in the U.S. markets. Currently, a significant percentage of our U.S. sales are to national Tier-1 telecommunications providers with multiple facilities. Since 2021, we increased our efforts to diversify our sales efforts to include Tier-2 telecommunications customers, off-grid remote area products and residential charging. In the international markets, our customers are regional Tier-1 telecommunications providers. We have established sales offices in emerging markets like U.A.E., Australia, Poland and the Dominican Republic. Our sales team directly markets to Tier-1 telecommunications companies in their regions.

Experienced Management Team. Our Chief Executive Officer and key engineers combined have over 100 years of engineering and production experience in the design and manufacturing of power systems. Our engineers have equipment design experience, as well as hands-on skills to build prototypes. A key factor demonstrating our management’s abilities and our engineering aptitude can be found in our successful track record over the last 40 years of executing research, design and engineering contracts.

Business Strategy

For the past three decades we have been promoting the use of DC power systems where DC power is the primary power in use. The telecommunications tower application is the largest user of DC power, in both grid and off-grid connected sites. Furthermore, we believe that the growth in wireless telecommunications infrastructure in the U.S. and international markets has led to a rapid rise in the need for DC backup power systems.

With over 40 years of experience and reputation within the DC power systems market, we are working to increase awareness, availability and affordability of more efficient DC-based products as a backup power and charging sources within the telecommunications industry. Because of the increased power outages during emergencies and natural disasters, existing and new wireless installations need to be upgraded to provide reliable operations during times of emergency. The primary elements of our business strategy include:

Further develop U.S. mobile telecommunications market. We continue to invest capital into our sales and marketing efforts to demonstrate our DC power systems to the top Tier-1 wireless telecommunications providers and more than 500 small wireless and cable operators in the U.S. Our goal is to further diversify our customer base. We believe the rapid transition towards 5G will result in an increase in demand for back-up power generators and that our new LPG / natural gas DC power systems will allow us to better compete on an economic basis with our competitors that provide AC power systems.
Expand global sales to bad-grid or off-grid markets. The increase in telecommunications subscriber base in rural and remote areas in emerging countries has increased the deployment of telecommunications sites in off-grid and bad-grid areas. During 2023, approximately 75% of our DC power systems sales were to U.S. telecommunications customers, which we believe represents only 4.7% of the total global telecommunications market. We believe that the lack of a stable electric infrastructure in rural regions of many developing nations provides significant opportunity for our products in both off-grid and bad-grid location. During 2023, we demonstrated our products to several prospects in need of off-grid and/or bad-grid solutions which resulted in several initial orders.
Further develop our new LPG and natural gas DC power systems. With the increased growth in off-grid and bad-grid telecommunications sites, emissions generated by telecommunications towers is beginning to be a major contributor of pollution and greenhouse gases. Since 2019, we have developed lower emission LPG and natural gas DC power generators for use in rural off-grid and bad-grid sites. We initiated this development by partnering with world’s largest natural gas engine manufacturer, Toyota Engines, located in Japan. Subsequently, we integrated engine control systems utilizing control technology from Bosch, located in Germany, and concluded by receiving certification from the EPA in December 2019 to sell our new product in all 50 states in the U.S. Upon certification, we began marketing this low emission natural gas solution to telecommunications customers worldwide and in the midst of the COVID-19 pandemic we secured several orders for natural gas configured backup and prime power applications. During 2020, we began shipments of our DC natural gas generators to several domestic and international Tier-1 telecommunications customers. In 2024, we plan to expand our sales and service network for our natural gas generators, targeting residential and telecommunications customers in the U.S. while also targeting Tier-1 telecommunications customers in emerging nations with solar hybrid natural gas generators for off-grid markets.

Expand renewable solar energy product offerings. Developing regions like Africa, South East Asia and Latin America lack an electric utility infrastructure to support the installation of grid connected telecommunications towers in remote areas. Due to these challenges, telecommunications companies are installing hybrid power generation systems that consist of solar panels, batteries and fossil fuel powered generators. Installing fuel inefficient generators combined with solar and batteries without any integration is proving to be cost prohibitive. Several local government programs to subsidize the adoption of solar and battery storage along with generators in off-grid telecommunications towers have failed due to lack of quality components and integration. We believe our hybrid systems using natural gas fuel powered generators integrated with solar and battery storage offer an ideal solution for this market.

Our Technologies

Starting in 1979, Polar began manufacturing and exporting solar PV vaccine refrigerator/freezers as part of the WHO Cold Chain projects. We developed solar refrigeration and air conditioning systems that operated directly with DC batteries, along with solar photovoltaic charge controls. Our DC power and refrigeration technologies drew the attention of various military projects. We manufactured packaged remote home power systems for Arizona Public Service who in turn provided them to remote customers. The use of remote home power systems drew our attention to the need for DC generator sets.

In the early 1990’s, we began introducing DC generators to provide backup and prime power for off-grid and bad-grid applications. Our initial products were predominantly designed for military applications and used as auxiliary power for vehicles, battlefield tanks and radar sites. In the late 1990s, we introduced our DC power systems for commercial applications like mobile telecommunications towers, solar refrigerators and oil field applications.

We introduced our 6200 PMHH alternator, which combines the attributes of homopolar alternator technology with a permanent magnet. When mounted on an engine and operated at either a fixed or variable speed, the model 6200 PMHH generates a precise amount of regulated voltage and current. The DC output can then be used to power electronics or charge batteries.

We developed our own proprietary DC alternator to improve system efficiency, reduce costs and lower weight. Our design replaced a conventional 4-pole, three-phase designs with a light weight, low cost 12-pole incorporating either 6 or 3 phases. Another unique aspect of the design of our DC alternators is the elimination of bearings, internal wiring connections, and an exciter (i.e., a device which supplies the magnetizing current to generate working flux) to provide a longer life cycle than conventional motor designs in the marketplace.

In 2006, we introduced our next generation 8000 Series alternators designed for higher power and voltage applications, which features our proprietary 32-pole permanent magnet alternator technology. The 8000 Series offers high efficiency at a lower cost while integrating our proprietary digital control system, Supra Controller™, that manages and optimizes alternator output. Our Supra Controller™ networks all components via CAN bus communications and software and has the ability to control, analyze, monitor, record and communicate all key system parameters to ensure efficiency, safety and reliability of the overall system. The ability to remotely monitor and calibrate each system parameter, receive system alarms and auto-reset the system when a fault is corrected are the key differentiating factors of our DC power systems.

In telecommunications tower backup applications, backup generators are used to provide power during grid outages or to charge batteries to provide longer run times during emergencies. Due to battery costs and availability issues, many telecommunications providers are known to use various types of chemistries or capacities as storage sources. During the past decade, we have successfully integrated various battery chemistry charge algorithms into our Supra Controller™ software.

In 2011, we added charge algorithms for various lithium battery chemistries and integrated our proprietary battery management system, or BMS, with our Supra Controller™ software. In 2013, we further expanded the integration of storage and renewable energy such as solar and wind into our Supra Controller™ software resulting in the shipment of twenty off-grid telecommunications tower power systems to Australia.

In 2017 and 2018, we demonstrated our DC hybrid power systems to telecommunications providers in South East Asia and Africa. We believe that the integration of renewable energy and storage batteries are ideal for off-grid remote locations in rural areas worldwide. During 2024, we plan to continue our research and development efforts to further enhance these integrations for remote telecommunications towers in South East Asia and Africa.

In 2018, we developed our next generation BMS that enhances our current technology to more accurately measure, monitor, control and integrate battery performance data with our Supra Controller™. In addition, we enhanced the user interface to allow us the ability to update or develop new charging algorithms in the field which can be remotely programmed or uploaded.

In 2018, we introduced our Toyota natural gas / propane engine across our product line. The Toyota product is a more advanced engine used in heat pump applications. We have negotiated a supply agreement with Toyota for the engine and with Bosch for the ignition control. In December 2019, we received our certificate of conformity from the EPA. These new generators provide power outputs between 5 kW to 15 kW and incorporate a 60,000- to 90,000-hour life engine with our proprietary control system. We are presently marketing these stationary generators within the telecommunications, commercial and residential markets.

In 2021, we began development of a higher power natural gas-powered DC backup power system utilizing larger engines and improved emission control systems. The implementation of 5G networks by Tier-1 telecommunication customers currently have significantly higher power requirements at cell sites than the previous 4G networks. In addition, use of 5G technology in IoT, video streaming, and data analytics applications requires cell sites to be operational 100% of the time which, in turn, increases the demand for reliable and fuel-efficient power generation backup systems. We believe increased power usage of 5G networks and higher fuel prices enhances market opportunities for our fuel-efficient DC power systems as compared to lower efficiency AC power systems. In March 2022, we received our EPA certification on our 4Y Toyota engine, which is a larger engine model for used on our 20 to 30 kW DC power systems. We believe being an approved supplier for the three largest Tier-1 telecommunication providers in the U.S. provides us with additional growth opportunities during the current rapid 5G expansion in the largest urban centers in the U.S.

Products and Services

DC Base Power Systems

Our DC base power systems are designed for use in prime power and backup power applications. All of our DC power systems are designed to last 20 years or more in backup applications and meet all UL2200 standards. To maximize operational life, we incorporate (over and above our competition) the following:

all aluminum, powder coated, enclosure with stainless hardware, which is lightweight and corrosion resistant;
105 C rated signal wire, tinned copper strands;
stainless steel braided covering hoses for fuel and coolant lines;
Class 220 C magnet wire for alternator windings;
watertight connectors in place of terminal strips and other non-sealed connectors; and
our proprietary Supra Controller™ modules that are environmentally sealed.

We believe that the number one reliability issue with a generator set is the failure to start. To improve the reliability of our generators, we remove the engine’s starting battery and replace it with a super capacitor. The super capacitor has a 15- to 20-year service life, greater cold cranking amps and withstands greater temperature extremes than conventional starting batteries.

To reduce maintenance and help ensure that there is always adequate oil, we increase the engine’s oil capacity to provide for a 4,300-hour (natural gas / propane) or 1,500-hour (diesel) maintenance interval. Standard oil intervals for typical generators range from 200 to 500 hours.

DC Hybrid Power Systems

In most off-grid or bad-grid outdoor applications where DC loads are required, such as telecommunications towers in rural or remote areas, generator fuel cost can account for more than 60% of the total operating costs.

In most backup applications, such as telecommunications and uninterruptable power supply systems, lead acid batteries are used for providing transitional power prior to the backup generator start-up. In most of our prime power applications (including telecommunications) the goal is to reduce maintenance and fuel costs. Our Supra Controller™ automatically cycles the generator off when the loads are small and cycles it on again when the load increases or the battery charge is depleted. This cycling reduces engine maintenance and saves significant quantities of fuel.

Additional fuel savings are realized by using lithium-ion batteries in place of lead acid batteries. Lead acid batteries, when compared with lithium-ion batteries, have high internal resistance, are inherently inefficient during charging or discharging in cyclic load applications and therefore require longer to charge, resulting in higher fuel costs. In 2011, we completed the design and testing of a hybrid power system, where our DC power system was integrated with lithium-ion batteries to provide a longer life and higher fuel efficiency for cyclic DC power applications such as telecommunications towers. In 2019, we implemented our next generation BMS for our lithium battery storage system. This next generation BMS enhances battery charging accuracy, integrates with engine controls and provides additional protection for the lithium batteries.

Our DC hybrid power systems can monitor the charge/discharge cycle of various battery chemistries, including lithium-ion and lead acid batteries. Our Supra Controller™ system incorporates a CAN bus communications capability that provides communication and control between the battery and the DC hybrid power system. Each cell in the battery pack is individually monitored for voltage and temperature, ensuring the safety and longevity of the battery bank. These power systems include enclosures, a lithium-ion battery pack, our proprietary BMS and our proprietary Supra Controller™ system that controls engine output, battery charging algorithms, cooling system and power control circuits that optimize DC load outputs.

DC Solar Hybrid Power Systems

Our DC solar hybrid power system combines our DC hybrid power system with solar photovoltaic modules and a custom engineered multi power point tracking charge controller. In most off-grid or bad-grid outdoor applications, such as telecommunications towers in rural or suburban areas, the fuel costs of operating a generator can account for more than half of the total operating costs. We believe that incorporating renewable energy sources, such as solar, with our DC hybrid power systems is ideal solution for numerous off-grid and bad-grid applications worldwide. Our DC solar hybrid power systems incorporate the following features:

Hybrid power panel. We produce distribution panel assemblies that make use of punched and plated buss bars to make the heavy current connections between appliances. The industry standard is using labor intensive hand crimped wires and lugs which are accomplished in the field.
Photovoltaic Arrays. Our telecommunications customers request photovoltaic array structures to withstand winds of 150 mph and 200 mph exceeding the industry standard of 120 mph.
Shelter. We provide an all-weather light-weight aluminum walk-in shelter that is easy to transport by truck or helicopter.

Lightning protection. We provide the highest degree of lightning protection through the use of air-coil type inductors designed by us.
Air-Conditioning. We provide DC air-conditioning if required in very hot weather environments. We also provide cooling systems using ambient air.

Our environmentally friendly solar hybrid power systems based on a combination of solar with LPG and propane power sources offer significant cost savings in capital expenditures and operating expenditures when compared to similar products offered by our competitors. Our solar hybrid power systems have been specifically designed to run in residential applications and provide power outputs between 5 kW to 22 kW and incorporate a 30,000- to 90,000-hour life engine with our proprietary control system. Our natural gas generators when integrated with battery storage and solar are ideal microgrids for off-grid and bad grid residential and commercial applications.

Service and Support

Global Network Management Tools

We offer global network management services through our telematics tool, which consists of our Supra Controller™ technology integrated with monitoring software. This hardware is integrated into each DC power system and collects critical data from the equipment and transmits this data back to the customer and our service department. This capability allows us and our customers to monitor system performance remotely and to remotely update the equipment with new revision software in the field.

Our telematics capabilities and services include:

automated and continuous remote monitoring with auto alerts and notifications that can be transmitted via email or text messaging;
maintenance management, which provides ability to schedule preventative maintenance based on actual equipment usage; and
real-time, bi-directional communication capability for remote upgrades, testing and troubleshooting.

Our telematics tools also provide information to our customers on specific equipment utilization that provides the abilities to determine the functional status of the equipment and proactively schedule maintenance. We believe these tools assist in reducing equipment downtime, thereby reducing the overall cost of ownership. In addition, we plan to use these tools to monitor and provide accurate billing for our rental equipment deployed at customer facilities.

Aftermarket and Service Parts

We offer extensive aftermarket and service parts programs. We maintain an extensive inventory of aftermarket parts and sell parts directly to customers or through our qualified network of service providers. In addition, we require our regional service providers to maintain sufficient quantities of aftermarket parts in their inventory to ensure minimum downtime upon product failure.

We maintain accurate records of bill of materials for each serial number shipped and service our products well beyond their recommended lives. In the marketplace, our products are known for their long life and durability.

Product and Warranty Support

We utilize a nationwide network of dealers and service providers to perform installation and warranty services for our customers. Through our dealers we offer product commissioning as an added service to all our customers and require the purchase of such services as a condition for acceptance of any warranty claims in the future. We offer installation of the equipment, preliminary testing, integration of equipment with other assets located at the site and introductory maintenance and safety training. We offer various levels of fee-based services to support our products in the field. In addition, we have trained product and application engineers that deliver high quality, responsive lifetime technical support to all our customers worldwide.

We further support our customers by using qualified regional independent service providers to perform warranty and aftermarket service and repair on our products. Our regional service providers are factory trained and certified prior to being authorized to repair or service our equipment. We generally reimburse regional service providers for the warranty services they perform on our systems.

Sales and Marketing

Our sales strategy focuses on using our direct sales force to market our DC backup power products to telecommunications providers in the U.S. We use local regional sales managers in the U.S. market to demonstrate our products to Tier-1 telecommunications providers. Our products are purchased by regional centers operated by our telecommunications customers, thereby expanding our overall market into regions we may not have covered previously.

We have established a sales and service infrastructure in international markets. We established regional sales offices in Australia, U.A.E., Poland and Dominican Republic and established sales and aftermarket service locations in Australia and Romania to manage the South East Asia and EMEA regions, respectively. Due to a general lack of a reliable power grid, many emerging markets continue to expand their telecommunications infrastructures at a high rate. We believe that this lack of a reliable power grid, together with our knowledge of integrating renewables with generators, provides us with an opportunity to enter these emerging markets with our hybrid storage and renewable energy solutions.

We also market our products through our web site and by exhibiting our products at industry trade shows globally. Our primary sales are generated through product demonstrations and short-term rentals to demonstrate the capabilities of our products and value proposition to large mobile network providers worldwide. We believe this strategy of demonstrating our products and technologies to prospective customers expedites the sales process for our DC power systems.

Distribution and Service

We service our products through various service partners that provide initial product installation and maintenance services. The promotion of our natural gas powered Mini-Grid product, targeting off-grid and bad grid rural areas, will be undertaken by certified independent dealers. We believe expansion of our dealer network will also provide additional opportunities for our DC power systems in the U.S. and other countries.

We utilize a combination of factory trained technicians and independent service providers to provide installation, maintenance, service and training at customer locations throughout the U.S.

In the international markets, we utilize local service partners to perform installation and service on our equipment. We have hired trained personnel in Australia, Romania, and South Africa to assist in regional training of technicians and also in product demonstrations.

Competition

Within the telecommunications power generation market, we compete with a few manufacturers of AC and DC generators that offer generators with an output power of 5 kW to 50 kW. In the U.S. market, our competitors are global manufacturers of AC generators designed primarily for the residential and industrial off-grid power markets. Internationally, our competitors include regional manufacturers of both AC and DC generators.

In the U.S. market, our competitors are large volume manufacturers of AC generators with a primary focus on emergency power backup generation for the residential marketplace. These AC generators are constructed using steel enclosures and are therefore heavier and can rust more easily in outdoor applications as compared to our products which generally have a smaller footprint and are constructed using aluminum enclosures. Due to the inherent design of AC motors, their units are approximately 40% larger in size than our DC generators. In order to monetize on our positives, we targeted telecommunications markets where generators are used to provide backup power during power outages. Due to the lighter weight and smaller size of our products as compared to AC products, we specifically target customers with the telecommunications towers located on roof-tops in urban areas. We believe that the smaller size, lighter weight and higher fuel efficiency of our products are performance parameters that offset the lower price alternative of AC generators. In addition, we believe that our recently introduced long-life (90,000 hours), natural gas-powered DC generator product line significantly increases our competitive advantage in densely populated urban markets.

Increased digitization of our lives has resulted in the need for more power usage in both residential and commercial applications. In the telecommunications tower market, the majority of the outdoor power needs are DC power since most components are DC powered. Historically, AC generator companies have utilized conversion technologies to convert AC output to DC output. This conversion results in an approximately 40% loss in energy. Meanwhile, our DC generators supply DC power directly to the telecommunications tower systems increasing the system’s overall efficiency. These efficiencies are further enhanced in off-grid and bad-grid applications where more power is being used from the generators due to the lack of grid power.

Below are our primary competitors across these applications:

DC Power: 3Tech Corporate Limited, Ascot Industrial srl, Ausonia srl, and Controllis.

AC Power: Generac Power Systems, Inc., Kohler Co., Onan, FG Wilson and many other companies.

Manufacturing and Assembly

A significant percentage of our business comes from multinational global corporations seeking configured product solutions ready to be field deployed with a minimum installation time. Our manufacturing process begins with our direct sales force and engineering team defining customer application needs and concludes with the production of a custom configured product solution. We believe our ability to have total control over the sales and manufacturing process is a key competitive differentiator in the markets we serve.

By implementing vertical integration throughout our manufacturing process, we believe that we reduce overall manufacturing costs, thereby increasing profitability and market competitiveness. Our production processes encompass all aspects of production of our DC power systems, which includes alternators, aluminum enclosures, engine configurations, control electronics, cooling systems, wiring harnesses, exhaust systems and final assembly. Manufacturing of our proprietary technologies requires proprietary automated equipment that ensures total control and agility in our production processes. Over the past decade, we have made significant investments in highly specialized manufacturing tooling, jigs and fixtures that allow us to manufacture products at lower cost while maintaining the highest quality.

Our production assembly lines are designed to be flexible, and we utilize advanced manufacturing planning software to predict, monitor and control demand levels and product mix to provide the shortest delivery time to our customers. We utilize 3-D CAD software to product design and document assembly instructions throughout our production process. All our products are 100% tested to customer specific application requirements prior to shipment.

Throughout our operations we utilize computerized ERP software that integrates all our processes from lead generation to product shipment and aftermarket support. Our focus on safety, quality and on-time delivery is supported by employee training and information systems that monitor process and product quality and communicate trends and findings to senior management on a real-time basis.

Design Engineering/Research and Development

Our research and development efforts are market driven and are focused on the development of new technologies and product improvements, as well as reducing costs and improving product quality and reliability. The primary focus of our research and development activities is the development of lighter-weight, more compact and lower cost DC power generation systems for our Tier-1 wireless provider customers in the U.S. and international markets. Over the years, we have expended significant resources in enhancing our system controls like our Supra Controller™ and BMS.

A significant part of our research and development effort has focused on the development of control software that integrates engine controls, power management and battery algorithms to fully optimize fuel consumption in both prime power and backup power generation applications. We use a high level of integration with a single control and communication module, our Supra Controller™, rather than competitive system designs with a number of independent control modules controlling a single function. Our integrated approach ensures software compatibility, reduces complexity in wiring, increases reliability and reduces cost. We maintain an in-house design, prototyping, testing and application engineering capabilities including expertise in 3-D solid modeling and finite element analysis, computer-based modeling and testing, rapid prototyping, design verification testing and document publication, which includes manufacturing assembly instructions, supplier drawings and product manuals. In addition, we utilize third party testing laboratories to certify our products’ compliance with current applicable UL standards.

Our research and development efforts are key to meeting customer demand and ever-changing power requirements. In 2024, we plan to gradually increase our team of engineers and continue investing into new product development as part of our strategy to diversify our product lines.

Intellectual Property

We possess a broad intellectual property portfolio comprised of electronics, software, engines, alternators, thermal systems and production techniques. We rely on trademark, copyright and trade secret laws to protect our intellectual property. Currently, we rely on common law rights to protect our “Polar Power, Inc.” trade name. We protect our trade secrets and other proprietary information by requiring confidentiality agreements from our employees, consultants and third parties that have access to such information. Despite these efforts, there can be no assurance that others will not gain access to our trade secrets, or that we can meaningfully protect our technology. In addition, effective trademark, copyright and trade secret protection may be unavailable or limited in certain foreign countries.

We consider our manufacturing process to be a trade secret and have non-disclosure agreements with our employees to protect the trade secrets held by us. However, such methods may not afford complete protection, and there can be no assurance that others will not independently develop similar know-how or obtain access to our know-how and manufacturing concepts. We may register patents and trademarks in future to protect our intellectual property rights and enhance our competitive position.

Suppliers

We attempt to mitigate the adverse effect of component shortages in our business through detail material planning and by qualifying multiple vendor sources for key components and outside processes. We conduct supplier audits of all major suppliers for initial qualification and to ensure reliability, quality, and sustainability of critical components. To meet our customer demands, we forecast the supply of our long lead time items such as engines, castings and electronic components through use of sales forecasting tools and ERP system.

Our suppliers are extensively surveyed and audited; and field or process generated non-conformities communicated with our Suppliers to continuously improve quality. To improve our costs and deliveries, our ERP system invites for all qualified suppliers to participate in relevant bids to ensure best proposals are selected.

We have experienced material shortages and delays due to the pandemic; more in 2022 than in 2023. We actively sourcing the global supply chain for key components to avoid or reduce the risk of future delays or interruptions to our operations or our ability to service customers. We have also experienced price increases on certain materials and freight services. Although we believe we can mitigate a portion of material price increases by passing through some cost increases to our customers, we believe a fair portion can be mitigated through increases in efficiency.

Quality Control

Our quality control is established to maintain the highest level of quality in the manufacturing of our DC power systems, spare parts, and services. The foundation of our quality control was initially set in the early 1980s, much of which was required by our customers at the time, including NASA and Hughes Aircraft. In the late 1980s, we implemented the MIL-I-45208A quality control system monitored by U.S. Department of Defense, to meet prime source requirements for a contract we received from the U.S. Army Picatinny Arsenal to design and manufacture an advanced battery and monitoring system for a security device used in nuclear munitions depots around the world. We are currently in the process of obtaining an ISO 9000 certification.

Certifications

Our DC generator systems comply with UL2200 safety standards. Our products also comply with applicable regulatory emission standards of the Environmental Protection Agency, and the California Air Quality Management District.

Product Warranties

The Company provides limited warranties for parts and labor at no cost to its 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 a product not perform as expected. Under our standard warranty, 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.

Information Systems

We utilize integrated information systems (i.e., ERP) that link our lead management, sales planning, order entry, purchasing, engineering, production control, manufacturing, inventory and accounting systems. During the past five years we have made significant investments to upgrade and customize our information systems to improve productivity and our ability to accurately forecast inventory and manpower requirements. We plan to invest additional capital in software and information systems to integrate aftermarket sales and service with our ERP system to improve post sales customer experience with our products and services.

Government Regulations and Environmental Matters

Our business operations are subject to certain federal, state, local and foreign laws and regulations. For example, our products, services and technologies are subject to regulations relating to building codes, public safety, electrical connections, security protocols, and local and state licensing requirements. The regulations to which we are subject may change, additional regulations may be imposed, or existing regulations may be applied in a manner that creates special requirements for the implementation and operation of our products or services that may significantly impact or even eliminate some of our revenues or markets. In addition, we may incur material costs or liabilities in complying with any such regulations. Furthermore, some of our customers must comply with numerous laws and regulations, which may affect their willingness and ability to purchase our products, services and technologies.

Additionally, we are subject to laws, regulations and other governmental actions instituted in response to the COVID-19 outbreak.

The modification of existing laws and regulations or interpretations thereof or the adoption of future laws and regulations could adversely affect our business, cause us to modify or alter our methods of operations and increase our costs and the price of our products, services and technology. In addition, we cannot provide any assurance that we will be able, for financial or other reasons, to comply with all applicable laws and regulations. If we fail to comply with these laws and regulations, we could become subject to substantial penalties or restrictions that could materially and adversely affect our business.

Human Capital

Our experienced employees and management team are our most valuable resources, and we are committed to attracting, motivating, and retaining top professionals to service our customers. As of April 1, 2024, we had 87 full time employees, which includes 80 employees in the U.S. and 7 employees outside the U.S. None of our employees are represented by labor unions. We consider our relationships with our employees to be generally satisfactory. In addition, from time to time, we utilize outside consultants or contractors for specific assignments.

We believe our success is directly related to the satisfaction, growth, and development of our employees. We strive to offer a work environment where employee unique characteristics and opinions are valued and one that provides our employees the opportunities to use and augment their professional skills. To achieve our human capital goals, we intend to remain focused on providing our personnel with career development opportunities to expand our business within their areas of expertise and continue to provide our personnel with personal and professional growth.

Risks Related to Our Business and Industry

Going Concern

The COVID-19 pandemic has had, and will likely continue to have, a significant negative impact on our business, sales, results of operations and financial condition.

The COVID-19 pandemic has had a widespread and detrimental effect on the global economy, particularly in the U.S. since 2020, but to a lesser extent in 2023. The repercussions of COVID-19 is likely to continue to have, a material and substantial adverse impact on our results of operations, including a decrease in our sales and delays in sourcing raw materials from suppliers.

In addition, COVID-19 adversely affected the economies and financial markets of many countries, which may affect our level of indebtedness, our need to generate sufficient cash flows to service our indebtedness and our ability to comply with the covenants contained in the agreements that govern our indebtedness. In the event of a sustained market deterioration and continued declines in net sales, and other repercussions of COVID-19, we may need additional liquidity. The need for additional liquidity may also be affected by the federal government’s potential failure to raise the debt ceiling or correct a prolonged banking or financial crisis. Such disruptions may impact the broader capital markets, and in turn, may impact our ability to access those markets. We cannot provide any assurance that we will be able to obtain additional sources of financing or liquidity on acceptable terms, or at all.

The ultimate impact of the COVID-19 pandemic on our business and results of operations remains unknown and will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration and potential resurgence of COVID-19, repeat or cyclical outbreaks and any additional preventative and protective actions that governments, or we, or our customers, or our suppliers may direct, which may result in an extended period of continued business disruption and reduced operations. Any resulting financial impact cannot be reasonably estimated at this time, but we expect it will continue to have a material impact on our business, financial condition and results of operations.

Rising inflation in the economies in which we operate may adversely affect our operating margins and our results of operation.

In general, we believe that our results of operations are not dependent on moderate changes in the inflation rate. Historically, we have been able to manage the impacts of more significant changes in inflation rates through our customer relationships, customer agreements that may provide for price increases and continued focus on improvements of operational productivity. However, the current inflationary environment has, we believe, has impacted the Company’s business in 2022 and 2023 and may continue to impact its business in 2024, including as a result of increased energy costs, as well as increasing wages in the labor markets in which we compete. Inflation could continue to pressure our margins in future periods. In addition, in response to the concerns over inflation risk in the broader U.S. economy, the U.S. Federal Reserve has been steadily increasing its benchmark interest rate since March 2022 and has signaled that additional rate increases will continue in 2024. It is possible that increases in interest rates may ultimately result in an economic recession, which could have a material adverse impact on our business. Adverse economic conditions resulting from inflationary pressures, U.S. Federal Reserve actions, geopolitical issues or otherwise are difficult to predict and may have a material adverse impact on our business, results of operations and financial condition.

Terrorist attacks and threats of war may impact all aspects of our operations, revenues, costs and stock price in unpredictable ways.

The impacts of war and other geopolitical events, including but not limited to Russia’s invasion of Ukraine and the Hamas-Israel conflict and the resulting war, are difficult to predict. The resulting geopolitical uncertainty are likely to have a significant impact on the European Union, the United Kingdom and other countries, including the U.S. The threat that these military operations may expand beyond Ukraine, Israel, and the Gaza Strip may have a negative impact as well. Significant increases in the price of oil and natural gas have occurred and are likely to continue putting additional inflationary pressures on central banks, including Federal Reserve System (the “FRB”). It is possible that interest rate hikes by the FRB will continue to occur in 2024, but the amount, timing, and frequency of such increases are not fully known at this time. As a result of these conflicts, the threat of cyberattacks has increased which could affect banks in the U.S. and their customers. Additionally, the United States and European nations have imposed very significant financial sanctions on the Russian Federation, including targeted sanctions on Russian banks and wealthy individuals as well as halting certification of the Nord Stream 2 gas pipeline. They have denied Russian banks access the Society for Worldwide Interbank Financial Telecommunications or SWIFT which is expected to slow international trade and make such transactions costlier to accomplish which could also negatively affect banks in the U.S. and their customers. In response to the Russian military actions, many businesses headquartered in the Eurozone and the United States have stopped doing business with Russia, which may negatively affect the profitability of those companies. The international turmoil has already had and may continue to have a negative impact on the stock market generally and, in turn, on our stock price.

The continuation or escalation of events like the war in Russia-Ukraine war or the Hamas-Israel conflict may also disrupt business operations of our suppliers and/or customers, causing supply chain constraints or delayed spending by our customers. The full impact of the such events are not known at this time, but they could have a material adverse impact on our business, financial condition, results of operations, and stock price.

We have incurred significant losses in the past and we may incur losses in the future, which may hamper our operations and impede us from expanding our business.

We have incurred significant losses in the past. For the years ended December 31, 2023 and 2022, we incurred net losses of approximately $6.5 million and $5.6 million, respectively. For the year ended December 31, 2023, we incurred a gross profit of approximately $0.7 million, and for the year ended December 31, 2022, we incurred a gross profit of approximately $2.1 million. We may incur net and gross losses in the future. We expect to rely on cash on hand, cash, if any, generated from our operations, borrowing availability under our line of credit and proceeds from our future financing activities, if any, to fund all of the cash requirements of our business. Additional losses may hamper our operations and impede us from expanding our business.

We are dependent on, and derive substantially all of our revenue from, sales of our DC base power systems to one customer within the U.S. telecommunications market. Our efforts to expand our customer base, our product portfolio or markets within which we operate may not succeed and may reduce our revenue growth rate.

We derive substantially all our revenues from sales of our DC base power systems to one customer within the telecommunications market, AT&T. The volume of sales to them may vary significantly from year to year. Any factor adversely affecting sales of these power systems to this customer or to other customers within this market, including market acceptance, product competition, performance and reliability, reputation, price competition and economic and market conditions, could adversely affect our business and results of operations.

In addition, any unfavorable change in our business relationship with our Tier-1 telecommunications wireless carrier customers, or delays in customer implementation and deployment of our products, could have a material adverse effect on our results of operation and financial condition. Our plans to invest in the development of electric vehicle chargers, residential and commercial power products and higher capacity DC hybrid solar systems may not result in an anticipated growth in sales and may reduce our revenue growth rate.

Many of our DC power systems involve long design and sales cycles, which could have an adverse impact on our results of operations and financial performance.

The design and sales cycle for our DC power systems, from initial contact with our potential customer to the shipments of our product, may be lengthy. Customers generally consider a wide range of factors before making a purchase decision. Prior to purchasing our products, many of our customers often require a significant technical review, tests and evaluations over long periods of time (i.e., three to twenty-four months), assessments of competitive products and approval at a number of management levels within their organization. During the time our customers are evaluating our products, we may incur substantial sales and service, engineering and research and development expenses to customize our products to meet customer’s application needs. We may also expend significant management efforts, increase manufacturing capacity, order long-lead-time components or purchase significant amounts of components and other inventory prior to receiving an order. Even after this evaluation process, a potential customer may not purchase our products.

The product development time before a customer agrees to purchase our DC power systems can be considerable. Our process for developing an integrated solution may require use of significant engineering resources, including design, prototyping, modeling, testing and application engineering. The length of this cycle is influenced by many factors, including the difficulty of the technical specification and complexity of the design and the customer’s procurement processes. A significant period may elapse between our investment of time and resources in designing and developing a product for a customer and receipt of revenue from sales of that product. The length of this process, combined with unanticipated delays in the development cycles or delays in our ability to demonstrate our products to current and potential customers could materially affect our results of operations and financial conditions.

We do not have long-term commitments for significant revenues with most of our customers and may be unable to retain existing customers, attract new customers or replace departing customers with new customers that can provide comparable revenues and profits.

Because we generally do not obtain firm, long-term volume purchase commitments from our customers, most of our sales are derived from individual purchase orders. We remain dependent upon securing new purchase orders in the future in order to sustain and grow our revenues. Accordingly, there is no assurance that our revenues and business will grow in the future. Our failure to maintain and expand our customer relationships could materially and adversely affect our business and results of operations.

The current high concentration of our sales within the telecommunications market could result in a significant reduction in sales and negatively affect our profitability if demand for our DC power systems declines within this market before we are able to make significant inroads with our diversification of markets and customers.

Currently, we are predominately focused on the manufacturing, marketing and sales of DC power systems to telecommunications companies. We may be unable to shift our business focus away from these activities to other potential markets for our products. Accordingly, the emergence of new competing DC power products or lower-cost alternative technologies within the telecommunications market may reduce the demand for our products. A downturn in the demand for our DC power systems within this market could materially and adversely affect our sales and results of operations.

We face inventory risk and may be required to write-off additional inventory in the future.

We value inventories at the lower of cost or net realizable value. If the estimated net realizable value is determined to be less than the recorded cost of the inventory, a provision is made to reduce the carrying amount of the inventory item to the lower net realizable value determination. Determination of the net realizable value may be complex, and therefore, requires management to make assumptions and to apply a high degree of judgment. In order for management to make the appropriate determination of net realizable value, the following items are commonly considered: inventory turnover statistics, inventory quantities on hand in our facilities, unfilled customer order quantities, forecasted consumer demand, current prices, competitive pricing, seasonality factors, consumer trends and performance of similar products or accessories. Subsequent changes in facts or circumstances do not result in the reversal of previously recorded write-downs.

If our estimates regarding net realizable value are inaccurate, including our estimates regarding our inventory, or changes in customer demand for our products in an unforeseen manner, we may experience additional write-downs of our inventory.

The unavailability or shortage, or increase in the cost, of raw materials and components could have an adverse effect on our sales and profitability.

Our operations require raw materials, such as aluminum, copper, engines, electronics, and permanent magnets. Commodities such as aluminum and copper are known to have significant price volatility based on global economic conditions. An increase in global economic outlook may result in significant price increases in the cost of our raw materials. In addition, we use Neodymium permanent magnets in our alternators, for which there are a limited number of global suppliers that can meet our standards. Increase in manufacturing of electric vehicles worldwide can have an adverse effect on the cost or supply of these magnets. At our current production volumes, we are unable to secure large quantities of these commodities at fixed prices; however, we do have multiple sources of supply for our raw materials to meet our near term forecasted needs. Various factors could reduce the availability of raw materials and components and shortages may occur from time to time in the future. An increase in lead times for the supply of raw materials due to a global increase in demand for commodities or other reasons may significantly increase the timing of receipt of such materials and/or increase the material costs of our products. For example, as a result of the COVID-19 pandemic, we are experienced both delays in sourcing, and price increases of, certain key components. As a result of these delays, our standard eight-week delivery time increased to fourteen weeks. In addition, if production was interrupted due to unavailability or shortage of raw materials and we were not able to find alternate third-party suppliers or re-engineer our products to accommodate different components or materials, we could experience disruptions in manufacturing and operations including product shortages, higher freight costs and re-engineering costs. If our supply of raw materials or components continues to be disrupted or our lead times extended, our business, results of operations or financial condition could be materially adversely affected.

The markets within which we compete are highly competitive. Many of our competitors have greater financial and other resources than we do and one or more of these competitors could use their greater financial and other resources to gain market share at our expense.

If our business continues to develop as expected, we anticipate that we will grow our revenues in the near future. If, due to capital constraints or otherwise, we are unable to fulfill our existing backlog in a timely manner and/or procure and timely fulfill our anticipated future backlog, our customers and potential customers may decide to use competing DC power systems or continue the use of AC power systems. If we are unable to fulfill the demand for products and services in a timely manner, our customers and potential customers may choose to purchase products from our competitors. Some of our larger competitors may be willing to reduce prices and accept lower margins in order to compete with us. In addition, we could face new competition from large international or domestic companies with established industrial brands and distribution networks that enter our end markets. Demand for our products may also be affected by our ability to respond to changes in design and functionality, to respond to downward pricing pressure, and to provide shorter lead times for our products than our competitors. If we are unable to respond successfully to these competitive pressures, we could lose market share, which could have an adverse impact on our results. We cannot assure that we will be able to compete successfully in our markets or compete effectively against current and new competitors as our industry continues to evolve.

Rapid technological changes may prevent us from remaining current with our technological resources and maintaining competitive product and service offerings.

The markets in which we and our customers operate are characterized by rapid technological change, especially within the telecommunications market. Significant technological changes could render our existing and potential new products, services and technology obsolete. Our future success will depend, in large part, upon our ability to:

effectively identify and develop leading energy efficient technologies;
continue to develop our technical expertise;
enhance our current products and services with new, improved and competitive technology; and
respond to technological changes in a cost-effective and timely manner.

If we are unable to successfully respond to technological change or if we do not respond to it in a cost-effective and timely manner, then our business will be materially and adversely affected. We cannot assure you that we will be successful in responding to changing technology. In addition, technologies developed by others may render our products, services and technology uncompetitive or obsolete. Even if we do successfully respond to technological advances, the integration of new technology may require substantial time and expense, and we cannot assure you that we will succeed in adapting our products, services and technology in a timely and cost-effective manner.

If we are unable to continue to develop new and enhanced products and services that achieve market acceptance in a timely manner, our competitive position and operating results could be harmed.

Our future success will depend on our ability to continue to develop new and enhanced DC power systems and related products and services that achieve market acceptance in a timely and cost-effective manner. The markets in which we and our customers operate are characterized by frequent introductions of new and enhanced products and services, evolving industry standards and regulatory requirements, government incentives and changes in customer needs. The successful development and market acceptance of our products and services depends on a number of factors, including:

the impact of a global crisis such as the COVID-19 pandemic on the global markets;
the changing requirements and preferences of the potential customers in our markets;
the accurate prediction of market requirements, including regulatory issues;
the timely completion and introduction of new products and services to avoid obsolescence;
the quality, price and performance of new products and services;
the availability, quality, price and performance of competing products and services;

our customer service and support capabilities and responsiveness;
the successful development of our relationships with existing and potential customers; and
changes in industry standards.

We may experience financial or technical difficulties or limitations that could prevent us from introducing new or enhanced products or services. Furthermore, any of these new or enhanced products and services could contain problems that are discovered after they are introduced. We may need to significantly modify the design of these products and services to correct problems. Rapidly changing industry standards and customer preferences and requirements may impede market acceptance of our products and services.

Development and enhancement of our products and services will require significant additional investment and could strain our management, financial and operational resources. The lack of market acceptance of our products or services or our inability to generate sufficient revenues from this development or enhancement to offset their development costs could have a material adverse effect on our business. In addition, we may experience delays or other problems in releasing new products and services and enhancements, and any such delays or problems may cause customers to forego purchases of our products and services and to purchase those of our competitors.

We cannot provide assurance that products and services that we have recently developed or that we develop in the future will achieve market acceptance. If our new products and services fail to achieve market acceptance, or if we fail to develop new or enhanced products and services s that achieve market acceptance, our growth prospects, operating results and competitive position could be adversely affected.

Natural disasters and other events beyond our control could materially adversely affect us.

Natural disasters or other catastrophic events, including the COVID-19 pandemic, may cause damage or disruption to our operations, international commerce and the global economy, and thus could have a strong negative effect on us. Our business operations are subject to interruption by natural disasters, fire, power shortages, pandemics and other events beyond our control. Although we maintain crisis management and disaster response plans, such events could make it difficult or impossible for us to deliver our services to our customers and could decrease demand for our services.

We are dependent on relationships with our key material suppliers, and the partial or complete loss of one of these key suppliers, or the failure to find replacement suppliers or manufacturers in a timely manner, could adversely affect our business.

We have established relationships with third-party engine suppliers and other key suppliers from which we source components for our power systems. We purchase standard configurations of engines for our DC power systems and are substantially dependent on timely supply from our key engine suppliers, Yanmar Engines Company, Perkins Engines Company Ltd, and Toyota Corporation. Engines from Yanmar, Perkins, and Toyota represented approximately 62%,26%, less than 2% of our total engines sold as a component of our DC power systems during 2023, respectively, and represented approximately 54%, 37%, and 1% of our total engines sold as components of our DC power systems during the same period in 2022, respectively. We also use engines from Isuzu, Kubota and, to a lesser extent, Volvo Penta. In December 2019, we received our certificate of conformity from the EPA with respect to our small spark-ignition Toyota engines which will be used in our new LPG / natural gas generators. The new Toyota engine serves as our primary engine in our new LPG products which were launched in 2020. In January 2022, we applied for EPA certification on our 4Y Toyota engine, which is a larger engine model for used on our 20 to 30 kW DC power systems. We do not have any long-term contracts or commitments with any of these suppliers. If any of these engine suppliers were to fail to provide emissions certified engines in a timely manner or fail to supply engines that meet our quality, quantity or cost requirements, or were to discontinue manufacturing any engines we source from them or discontinue providing any of these engines to us, or the supply chain is interrupted or delayed as a result of the COVID-19 pandemic or unprecedented event, and we were unable to obtain substitute sources in a timely manner or on terms acceptable to us, our ability to manufacture our products could be materially adversely affected.

Price increases in some of the key components in our DC power systems could materially and adversely affect our operating results and cash flows.

The prices of some of the key components of our DC power systems are subject to fluctuation due to market forces beyond our control, including changes in the costs of raw materials incorporated into these components. Such price increases occur from time to time due to spot shortages of commodities, increases in labor costs or longer-term shortages due to market forces. In particular, the prices of engines can fluctuate frequently and often significantly. We do not have any long-term contracts or commitments with our two key engine suppliers. Substantial increases in the prices of raw materials used in components which we source from our suppliers may result in increased prices charged by our suppliers. If we incur price increases from our suppliers for key components in our DC power systems, our production costs will increase. Given competitive market conditions, we may not be able to pass all or any of those cost increases on to our customers in the form of higher sales prices. To the extent our competitors do not suffer comparable component cost increases, we may have even greater difficulty passing along price increases and our competitive position may be harmed. As a result, increases in costs of key components may adversely affect our margins and otherwise adversely affect our operating results and cash flows.

A portion of our key components are sourced in foreign countries, exposing us to additional risks that may not exist in the U.S.

A portion of our key components, such as engines, magnets and cooling systems, are purchased from suppliers located overseas, primarily in Asia. Our international sourcing subjects us to a number of potential risks in addition to the risks associated with third-party sourcing generally. These risks include:

inflation or changes in political and economic conditions;
unstable regulatory environments;
changes in import and export duties;
currency rate fluctuations;
trade restrictions;
labor unrest;
logistical and communications challenges; and
other restraints and burdensome taxes.

These factors may have an adverse effect on our ability to source our purchased components overseas. In particular, if the U.S. dollar were to depreciate significantly against the currencies in which we purchase raw materials from foreign suppliers, our cost of goods sold could increase materially, which would adversely affect our results of operations.

The unavailability or shortage, or increase in the cost, of raw materials and components could have an adverse effect on our sales and profitability.

Our operations require raw materials, such as aluminum, copper and permanent magnets. Commodities such as aluminum and copper are known to have significant price volatility based on global economic conditions. An increase in global economic outlook may result in significant price increases in the cost of our raw materials. In addition, we use Neodymium permanent magnets in our alternators, for which there are a limited number of global suppliers that can meet our standards. Increase in manufacturing of electric vehicles worldwide can have an adverse effect on the cost or supply of these magnets. At our current production volumes, we are unable to secure large quantities of these commodities at fixed prices; however, we do have multiple sources of supply for our raw materials to meet our near term forecasted needs. Various factors could reduce the availability of raw materials and components and shortages may occur from time to time in the future. An increase in lead times for the supply of raw materials due to a global increase in demand for commodities outlined may significantly increase material costs of our products. If production was interrupted due to unavailability or shortage of raw materials and we were not able to find alternate third-party suppliers or re-engineer our products to accommodate different components or materials, we could experience disruptions in manufacturing and operations including product shortages, higher freight costs and re-engineering costs. If our supply of raw materials or components is disrupted or our lead times extended, our business, results of operations or financial condition could be materially adversely affected.

We manufacture and assemble a majority of our products at two facilities. Any prolonged disruption in the operations of this facility would result in a decline in our sales and profitability.

We manufacture and assemble our DC power systems at our two production facilities located in Gardena, California. Any prolonged disruption in the operations of our manufacturing and assembly facilities, whether due to the COVID-19 pandemic, equipment or information technology infrastructure failure, labor difficulties, destruction of or damage to one or both of these facilities as a result of an earthquake, fire, flood, other catastrophes, and other operational problems would result in a decline in our sales and profitability. In the event of a business interruption at our facilities, we may be unable to shift manufacturing and assembly capabilities to alternate locations, accept materials from suppliers or meet customer shipment needs, among other severe consequences. Such an event could have a material and adverse impact on our financial condition and results of our operations.

Our business operations are subject to substantial government regulation.

Certain of our products are used in critical communications networks which may subject us to significant liability claims.

Because certain of our products for customers in the telecommunications industry are used in critical communications networks, we may be subject to significant liability claims if our products do not work properly. We warrant to our customers that our products will operate in accordance with our product specifications. If our products fail to conform to these specifications, our customers could require us to remedy the failure or could assert claims for damages. The provisions in our agreements with customers that are intended to limit our exposure to liability claims may not preclude all potential claims. In addition, any insurance policies we have may not adequately limit our exposure with respect to such claims. Liability claims could require us to spend significant time and money in litigation or to pay significant damages. Any such claims, whether or not successful, would be costly and time-consuming to defend, and could divert management’s attention and seriously damage our reputation and our business.

We could be adversely affected by our failure to comply with the laws applicable to our foreign activities, including the U.S. Foreign Corrupt Practices Act and other similar worldwide anti-bribery laws.

The U.S. Foreign Corrupt Practices Act, or the FCPA, and similar anti-bribery laws in other jurisdictions prohibit U.S.-based companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. We may pursue opportunities in certain parts of the world that experience government corruption, and in certain circumstances, compliance with anti-bribery laws may conflict with local customs and practices. Our policies mandate compliance with all applicable anti-bribery laws. Further, we require our partners, subcontractors, agents and others who work for us or on our behalf to comply with the FCPA and other anti-bribery laws. Although we have policies and procedures, and have conducted training, designed to ensure that we, our employees, our agents and others who work with us in foreign countries comply with the FCPA and other anti-bribery laws, there is no assurance that such policies, procedures or training will protect us against liability under the FCPA or other laws for actions taken by our agents, employees and intermediaries. If we are found to be liable for FCPA violations (either due to our own acts or inadvertence, or due to the acts or inadvertence of others), we could suffer from severe criminal or civil penalties or other sanctions, which could have a material adverse effect on our reputation, business, results of operations or cash flows. In addition, detecting, investigating and resolving actual or alleged FCPA violations is expensive and could consume significant time and attention of our senior management.

We are exposed to risks related to our international sales, and the failure to manage these risks could harm our business. If we fail to expand our business into international markets, our revenues and results of operations may be adversely affected.

In addition to our sales to customers within the U.S., we may become increasingly dependent on sales to customers outside the U.S. as we pursue expanding our business with customers worldwide. During 2023, and 2022, our sales to international customers accounted for 21% and 25%, respectively, of total revenue. We continue to expect that a significant portion of our future revenues will be from international sales to customers in less developed or developing countries. As a result, the occurrence of any international, political, economic, or geographic event could result in a significant decline in revenue. There are significant risks associated with conducting operations internationally, requiring significant financial commitments to support such operations. These operations present a number of challenges including oversight of daily operating practices in each location, handling employee benefits and employee behavior. In addition, compliance with complex foreign and U.S. laws and regulations that apply to our international operations increases our cost of doing business in international jurisdictions. These numerous and sometimes conflicting laws and regulations include internal control and disclosure rules, data privacy and filtering requirements, anti-corruption laws, such as the FCPA, and other local laws prohibiting corrupt payments to governmental officials, and anti-competition regulations, among others.

Violations of these laws and regulations could result in fines and penalties, criminal sanctions against us, our officers, or our employees, prohibitions on the conduct of our business and on our ability to offer our products and services in one or more countries, and could also materially affect our brand, our international expansion efforts, our ability to attract and retain employees, our business, and our operating results. Although we have implemented policies and procedures designed to ensure compliance with these laws and regulations, there can be no assurance that our employees, contractors, or agents will not violate our policies.

Some of the risks and challenges of conducting business internationally include:

the impact of a global crisis such as a pandemic;/ on the global markets and the power generation market within the international telecommunications markets;
requirements or preferences for domestic products or solutions, which could reduce demand for our products;
unexpected changes in regulatory requirements;
imposition of tariffs and other barriers and restrictions;
restrictions on the import or export of critical technology;

management communication and integration problems resulting from cultural and geographic dispersion;
the burden of complying with a variety of laws and regulations in various countries;
difficulties in enforcing contracts;
the uncertainty of protection for intellectual property rights in some countries;
application of the income tax laws and regulations of multiple jurisdictions, including relatively low-rate and relatively high-rate jurisdictions, to our sales and other transactions, which results in additional complexity and uncertainty;
tariffs and trade barriers, export regulations and other regulatory and contractual limitations on our ability to sell products;
greater risk of a failure of foreign employees to comply with both U.S. and foreign laws, including export and antitrust regulations, the FCPA and any trade regulations ensuring fair trade practices;
heightened risk of unfair or corrupt business practices in certain geographies and of improper or fraudulent sales arrangements that may impact financial results and result in restatements of, or irregularities in, financial statements;
potentially adverse tax consequences, including multiple and possibly overlapping tax structures;
general economic and geopolitical conditions, including war and acts of terrorism;
lack of the availability of qualified third-party financing; and
currency exchange controls.

While these factors and the impacts of these factors are difficult to predict, any one or more of them could adversely affect our business, financial condition and results of operations in the future.

Cyberattacks through security vulnerabilities could lead to disruption of business, reduced revenue, increased costs, liability claims, or harm to our reputation or competitive position.

Security vulnerabilities may arise from our hardware, software, employees, contractors or policies we have deployed, which may result in external parties gaining access to our networks, data centers, cloud data centers, corporate computers, manufacturing systems, and/or access to accounts we have at our suppliers, vendors, and customers. External parties may gain access to our data or our customers’ data, or attack the networks causing denial of service or attempt to hold our data or systems in ransom. The vulnerability could be caused by inadequate account security practices such as failure to timely remove employee access when terminated. To mitigate these security issues, we have implemented measures throughout our organization, including firewalls, backups, encryption, employee information technology policies and user account policies. However, there can be no assurance these measures will be sufficient to avoid cyberattacks. If any of these types of security breaches were to occur and we were unable to protect sensitive data, our relationships with our business partners and customers could be materially damaged, our reputation could be materially harmed, and we could be exposed to a risk of litigation and possible significant liability.

Further, if we fail to adequately maintain our information technology infrastructure, we may have outages and data loss. Excessive outages may affect our ability to timely and efficiently deliver products to customers or develop new products. Such disruptions and data loss may adversely impact our ability to fulfill orders and interrupt other processes. Delayed sales or lost customers resulting from these disruptions could adversely affect our financial results, stock price and reputation.

The State of California enacted the California Consumer Privacy Act of 2018, or CCPA, effective on January 1, 2020. Our and our business partners’ or contractors’ failure to fully comply with the CCPA and other laws could lead to significant fines and require onerous corrective action. In addition, data security breaches experienced by us or our business partners or contractors could result in the loss of trade secrets or other intellectual property, public disclosure of sensitive commercial data, and the exposure of personally identifiable information (including sensitive personal information) of our employees, customers, suppliers, contractors and others.

Unauthorized use or disclosure of, or access to, any personal information maintained by us or on our behalf, whether through breach of our systems, breach of the systems of our suppliers or vendors by an unauthorized party, or through employee or contractor error, theft or misuse, or otherwise, could harm our business. If any such unauthorized use or disclosure of, or access to, such personal information was to occur, our operations could be seriously disrupted, and we could be subject to demands, claims and litigation by private parties, and investigations, related actions, and penalties by regulatory authorities. In addition, we could incur significant costs in notifying affected persons and entities and otherwise complying with the multitude of foreign, federal, state and local laws and regulations relating to the unauthorized access to, or use or disclosure of, personal information. Finally, any perceived or actual unauthorized access to, or use or disclosure of, such information could harm our reputation, substantially impair our ability to attract and retain customers and have an adverse impact on our business, financial condition and results of operations.

Risks Related to Our Intellectual Property

If we fail to adequately protect our intellectual property rights, we could lose important proprietary technology, which could materially and adversely affect our business.

Our success and ability to compete depends, in substantial part, upon our ability to develop and protect our proprietary technology and intellectual property rights to distinguish our products, services and technology from those of our competitors. The unauthorized use of our intellectual property rights and proprietary technology by others could materially harm our business.

Historically, we have relied primarily on a combination of trademark, copyright and trade secret laws, along with non-competition and confidentiality agreements, contractual provisions, licensing arrangements and proprietary software and manufacturing processes, to establish and protect our intellectual property rights. Although we hold several unregistered copyrights in our business, we believe that the success of our business depends more upon our proprietary technology, information, processes and know-how than on patents or trademark registrations. In addition, much of our proprietary information and technology may not be patentable; if we decided to apply for patents and/or trademarks in the future, we might not be successful in obtaining any such future patents or in registering any marks.

Despite our efforts to protect our intellectual property rights, existing laws afford only limited protection, and our actions may be inadequate to protect our rights or to prevent others from claiming violations of their proprietary rights. Unauthorized third parties may attempt to copy, reverse engineer or otherwise obtain, use or exploit aspects of our products and services, develop similar technology independently, or otherwise obtain and use information that we regard as proprietary. We cannot assure you that our competitors will not independently develop technology similar or superior to our technology or design around our intellectual property. In addition, the laws of some foreign countries may not protect our proprietary rights as fully or in the same manner as the laws of the U.S.

We may need to resort to litigation to enforce our intellectual property rights, to protect our trade secrets, and to determine the validity and scope of other companies’ proprietary rights in the future. However, litigation could result in significant costs and in the diversion of management and financial resources. We cannot assure you that any such litigation will be successful or that we will prevail over counterclaims against us. Our failure to protect any of our important intellectual property rights or any litigation that we resort to in order to enforce those rights could materially and adversely affect our business.

If we face claims of intellectual property infringement by third parties, we could encounter expensive litigation, be liable for significant damages or incur restrictions on our ability to sell our products and services.

Although we are not aware of any present infringement of our products, services or technology on the intellectual property rights of others, we cannot be certain that our products, services and technologies do not or in the future will not infringe on the valid intellectual property rights held by third parties. In addition, we cannot assure you that third parties will not claim that we have infringed their intellectual property rights.

In recent years, there has been a significant amount of litigation in the U.S. involving patents and other intellectual property rights. In the future, we may be a party to litigation as a result of an alleged infringement of others’ intellectual property. Successful infringement claims against us could result in substantial monetary liability, require us to enter into royalty or licensing arrangements, or otherwise materially disrupt the conduct of our business. In addition, even if we prevail on these claims, this litigation could be time-consuming and expensive to defend or settle and could result in the diversion of our time and attention and of operational resources, which could materially and adversely affect our business. Any potential intellectual property litigation also could force us to do one or more of the following:

stop selling, incorporating or using our products and services that use the infringed intellectual property;
obtain from the owner of the infringed intellectual property right a license to sell or use the relevant technology, which license may not be available on commercially reasonable terms, or at all; or
redesign the products and services that use the technology.

If we are forced to take any of these actions, our business may be seriously harmed. Although we carry general liability insurance, our insurance may not cover potential claims of this type or may not be adequate to indemnify us for all liability that may be imposed.

Risks Related to Our Common Stock

Our operating results can fluctuate significantly from period to period, which makes our operating results difficult to predict and can cause our operating results in any particular period to be less than comparable periods and expectations from time to time.

Our operating results have fluctuated significantly from quarter-to-quarter, period-to-period and year-to-year during our operating history and are likely to continue to fluctuate in the future due to a variety of factors, many of which are outside of our control. Certain factors that may affect our operating results include, without limitation, those set forth under “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies” in this Annual Report on Form 10-K.

Because we have little or no control over many of these factors, our operating results are difficult to predict. Any adverse change in any of these factors could negatively affect our business and results of operations.

Our revenues, net income and other operating results are heavily dependent upon the size and timing of customer orders and projects, and the timing of the completion of those projects. The timing of our receipt of large individual orders, and of project completion, is difficult for us to predict. Because our operating expenses are based on anticipated revenues over the mid- and long-term and because a high percentage of our operating expenses are relatively fixed, a shortfall or delay in recognizing revenues can cause our operating results to vary significantly from quarter-to-quarter and can result in significant operating losses or declines in profit margins in any particular quarter. If our revenues fall below our expectations in any particular quarter, we may not be able, or it may not be prudent for us, to reduce our expenses rapidly in response to the revenue shortfall, which can result in us suffering significant operating losses or declines in profit margins in that quarter.

Due to these factors and the other risks discussed in this Annual Report on Form 10-K, you should not rely on quarter-to-quarter, period-to-period or year-to-year comparisons of our results of operations as an indication of our future performance. Quarterly, period and annual comparisons of our operating results are not necessarily meaningful or indicative of future performance. As a result, it is likely that, from time to time, our results of operations or our revenue backlog could fall below historical levels or the expectations of public market analysts and investors, which could cause the trading price of our common stock to decline significantly.

Our Chairman, President and Chief Executive Officer owns a significant percentage of our common stock and will exercise significant influence over matters requiring stockholder approval, regardless of the wishes of other stockholders.

Our Chairman, President, Chief Executive Officer and Secretary, Arthur D. Sams, beneficially owns approximately 32% of our outstanding shares of common stock. Mr. Sams therefore has significant influence over management and significant control over matters requiring stockholder approval, including the annual election of directors and significant corporate transactions, such as a merger or other sale of our company or our assets, for the foreseeable future. This concentrated control may limit stockholders’ ability to influence corporate matters and, as a result, we may take actions that our stockholders do not view as beneficial. As a result, the market price of our common stock could be adversely affected.

The price of our shares of common stock is volatile, and you could lose all or part of your investment.

The trading price of our shares of common stock is volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control, including limited trading volume. In addition to the factors discussed in the “Risk Factors” section and elsewhere in this Annual Report on Form 10-K, these factors include, without limitation:

competition from existing technologies and products or new technologies and products that may emerge;
the loss of significant customers, including AT&T and Verizon Wireless;
actual or anticipated variations in our quarterly operating results;
failure to meet the estimates and projections of the investment community or that we may otherwise provide to the public;
our cash position;
announcement or expectation of additional financing efforts;
issuances of debt or equity securities;
our inability to successfully enter new markets or develop additional products;
actual or anticipated fluctuations in our competitors’ operating results or changes in their respective growth rates;
sales of our shares of common stock by us, or our stockholders in the future;
trading volume of our shares of common stock on The Nasdaq Capital Market;
market conditions in our industry;
overall performance of the equity markets and general political and economic conditions;
introduction of new products or services by us or our competitors;
additions or departures of key management, scientific or other personnel;

publication of research reports about us or our industry or positive or negative recommendations or withdrawal of research coverage by securities or industry analysts;
changes in the market valuation of similar companies;
disputes or other developments related to intellectual property and other proprietary rights;
changes in accounting practices;
significant lawsuits, including stockholder litigation; and
other events or factors, many of which are beyond our control.

Furthermore, the public equity markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, as well as general economic, political and market conditions such as recessions, interest rate changes or international currency fluctuations, may negatively impact the market price of our shares of common stock.

A decline in the price of our common stock could affect our ability to raise further working capital, which could adversely impact our ability to continue operations.

A prolonged decline in the price of our common stock could result in a reduction in the liquidity of our common stock and a reduction in our ability to raise capital. We may attempt to acquire a significant portion of the funds we need in order to conduct our planned operations through the sale of equity securities; thus, a decline in the price of our common stock could be detrimental to our liquidity and our operations because the decline may adversely affect investors’ desire to invest in our securities. If we are unable to raise the funds we require for all of our planned operations, we may be forced to reallocate funds from other planned uses and may suffer a significant negative effect on our business plan and operations, including our ability to develop new products or services and continue our current operations. As a result, our business may suffer, and we may be forced to reduce or discontinue operations. We also might not be able to meet our financial obligations if we cannot raise enough funds through the sale of our common stock and we may be forced to reduce or discontinue operations.

We do not anticipate paying cash dividends, and accordingly, stockholders must rely on stock appreciation for any return on their investment.

We have never declared or paid cash dividends on our capital stock. We intend to retain a significant portion of our future earnings, if any, to finance the operations, development and growth of our business. Any future determination to declare dividends will be made at the discretion of our board of directors, subject to applicable laws, and will depend on number of factors, including our financial condition, results of operations, capital requirements, contractual restrictions, general business conditions and other factors that our board of directors may deem relevant. As a result, only appreciation of the price of our common stock, which may never occur, will provide a return to stockholders.

Our failure to satisfy certain listing requirements may result in our common stock being delisted from the Nasdaq Capital Market, which may make it more difficult for our shareholders to sell shares of our common stock.

Our common stock is listed on Nasdaq. Nasdaq has several quantitative and qualitative requirements companies must comply with to maintain this listing, including a $1.00 minimum bid price per share (the “Bid Price Rule”). On November 24, 2023, we received a deficiency letter from the Listing Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) indicating that our common stock is subject to potential delisting from the Nasdaq because for a period of 30 consecutive business days, the bid price of our common stock has closed below the minimum $1.00 per share requirement for continued inclusion under Nasdaq Marketplace Rule 5550(a)(2) (the “Bid Price Rule”). The Nasdaq deficiency letter has no immediate effect on the listing of our common stock, and our common stock continues to trade on The Nasdaq Capital Market under the symbol “POLA” at this time.

The Nasdaq notice indicated that, in accordance with Nasdaq Marketplace Rule 5810(c)(3)(A), we will be provided 180 calendar days, or until May 22, 2024, to regain compliance. If, at any time before May 22, 2024, the bid price of our common stock closes at $1.00 per share or more for a minimum of 10 consecutive business days, Nasdaq staff will provide written notification that we have achieved compliance with the Bid Price Rule.

If we fail to regain compliance with the Bid Price Rule before May 22, 2024 but meet all of the other applicable standards for initial listing on The Nasdaq Capital Market with the exception of the minimum bid price, then we may be eligible to have an additional 180 calendar days, or until November 18, 2024, to regain compliance with the Bid Price Rule. If we do not regain compliance with the Bid Price Rule by the end of the compliance period (or the second compliance period, if applicable), our common stock will become subject to delisting. In the event that we receive notice that our common stock is being delisted, the Nasdaq listing rules permit us to appeal a delisting determination by Nasdaq to a hearings panel.

We intend to monitor the closing bid price of our common stock and may, if appropriate, consider available options to regain compliance with the Bid Price Rule, such as reverse stock split. However, there can be no assurance that we will be able to regain compliance with the Bid Price Rule or will otherwise be in compliance with other Nasdaq listing rules.

On December 18, 2023, Peter Gross, a member of the Board of Directors of the Company, resigned as a member of the Board of Directors of the Company. Mr. Gross, an independent director, served as a member of the audit committee, chair of the compensation committee and chair of the nominating and corporate governance committee of the Board at the time of his resignation. On January 5, 2024, the Company received a notification letter from Nasdaq that due to Mr. Gross’ resignation, the Company is no longer in compliance with Nasdaq Listing Rule 5605. Pursuant to Nasdaq Listing Rule 5605(c)(4), the Company is entitled to a cure period to regain compliance (i) until the earlier of the Company’s next annual shareholders’ meeting or December 18, 2024; or (ii) if the next annual shareholders’ meeting is held before June 17, 2024, then the Company must evidence compliance no later than June 17, 2024.

The Company intends to appoint an additional independent director to the Board and the committees prior to the end of the cure periods. However, there can be no assurance that we will be able to regain compliance with Nasdaq Listing Rule 5605 or will otherwise be in compliance with other Nasdaq listing rules.

If the stock is delisted, we may trade on the over-the-counter market, or even in the pink sheets, which would significantly decrease the liquidity of an investment in our common stock.

If securities or industry analysts do not publish research or reports or publish inaccurate or unfavorable research or reports about our business, our share price and trading volume could decline.

The trading market for our shares of common stock depends, in part, on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. If no securities or industry analysts undertake coverage of our company, the trading price for our shares of common stock may be negatively impacted. If we obtain securities or industry analyst coverage and if one or more of the analysts who covers us downgrades our shares of common stock, changes their opinion of our shares or publishes inaccurate or unfavorable research about our business, our share price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our shares of common stock could decrease and we could lose visibility in the financial markets, which could cause our share price and trading volume to decline.

We are not subject to the provisions of Section 203 of the Delaware General Corporation Law, which could negatively affect your investment.

We elected in our certificate of incorporation to not be subject to the provisions of Section 203 of the Delaware General Corporation Law, or Section 203. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. A “business combination” includes a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns (or, in certain cases, within three years prior, did own) 15% or more of the corporation’s voting stock. Our decision not to be subject to Section 203 will allow, for example, Arthur D. Sams, our Chairman, President, Chief Executive Officer and Secretary (who beneficially owns approximately 32% of our common stock) to transfer shares in excess of 15% of our voting stock to a third-party free of the restrictions imposed by Section 203. This may make us more vulnerable to takeovers that are completed without the approval of our board of directors and/or without giving us the ability to prohibit or delay such takeovers as effectively.

Some provisions of our charter documents and Delaware law may have anti-takeover effects that could discourage an acquisition of us by others, even if an acquisition would be beneficial to our stockholders, and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our certificate of incorporation and bylaws, as well as provisions of Delaware law, could make it more difficult for a third party to acquire us or increase the cost of acquiring us, even if doing so would benefit our stockholders. These provisions include:

a requirement that special meetings of stockholders be called only by the board of directors, the president or the chief executive officer;
advance notice requirements for stockholder proposals and nominations for election to our board of directors; and
the authority of the board of directors to issue preferred stock on terms determined by the board of directors without stockholder approval and which preferred stock may include rights superior to the rights of the holders of common stock.

These anti-takeover provisions and other provisions in our certificate of incorporation and bylaws could make it more difficult for stockholders or potential acquirers to obtain control of our board of directors or initiate actions that are opposed by the then-current board of directors and could also delay or impede a merger, tender offer or proxy contest involving us. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing or cause us to take other corporate actions you desire. Any delay or prevention of a change of control transaction or changes in our board of directors could cause the market price of our common stock to decline.

Our certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or other employees.

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws, or (iv) any action asserting a claim against us governed by the internal affairs doctrine.

For the avoidance of doubt, the exclusive forum provision described above does not apply to any claims arising under the Securities Act of 1933, as amended, or the Securities Act, or the Securities Exchange Act of 1934, as amended, or the Exchange Act. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder, and Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.

The choice of forum provision in our bylaws may limit our stockholders’ ability to bring a claim in a judicial forum that they find favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and our directors, officers, employees and agents even though an action, if successful, might benefit our stockholders. The applicable courts may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. With respect to the provision making the Delaware Court of Chancery the sole and exclusive forum for certain types of actions, stockholders who do bring a claim in the Delaware Court of Chancery could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near Delaware. Finally, if a court were to find this provision of our bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could have a material adverse effect on us.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. As a result, stockholders could lose confidence in our financial and other public reporting, which would harm our business and the trading price of our common stock.

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties encountered in their implementation could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404 of the Sarbanes-Oxley Act, or any subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our financial statements or identify other areas for further attention or improvement. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our common stock.

We are required to disclose changes made in our internal controls and procedures on a quarterly basis and our management is required to assess the effectiveness of these controls annually. However, for as long as we are a “non-accelerated filer” under SEC rules, our independent registered public accounting firm will not be required to attest to the effectiveness of our internal controls over financial reporting pursuant to Section 404. An independent assessment of the effectiveness of our internal controls could detect problems that our management’s assessment might not. Undetected material weaknesses in our internal controls could lead to financial statement restatements and require us to incur the expense of remediation.

We incur significant costs as a result of operating as a public company and our management expects to devote substantial time to public company compliance programs.

As a public company, we incur significant legal, accounting and other expenses due to our compliance with regulations and disclosure obligations applicable to us, including compliance with the Sarbanes-Oxley Act as well as rules implemented by the SEC and Nasdaq. The SEC and other regulators have continued to adopt new rules and regulations and make additional changes to existing regulations that require our compliance. In July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, was enacted. There are significant corporate governance and executive compensation related provisions in the Dodd-Frank Act that have required the SEC to adopt additional rules and regulations in these areas. Stockholder activism, the current political environment, and the current high level of government intervention and regulatory reform may lead to substantial new regulations and disclosure obligations, which may lead to additional compliance costs and impact, in ways we cannot currently anticipate, the manner in which we operate our business. Our management and other personnel devote a substantial amount of time to these compliance programs and monitoring of public company reporting obligations and, as a result of the new corporate governance and executive compensation related rules, regulations, and guidelines prompted by the Dodd-Frank Act and further regulations and disclosure obligations expected in the future, we will likely need to devote additional time and costs to comply with such compliance programs and rules. These rules and regulations cause us to incur significant legal and financial compliance costs and make some activities more time-consuming and costly.

To comply with the requirements of being a public company, we may need to undertake various activities, including implementing new internal controls and procedures and hiring new accounting or internal audit staff. The Sarbanes-Oxley Act requires that we maintain effective disclosure controls and procedures and internal control over financial reporting. We are continuing to develop and refine our disclosure controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file with the SEC is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that information required to be disclosed in reports under the Exchange Act, is accumulated and communicated to our principal executive and financial officers. Our current controls and any new controls that we develop may become inadequate and weaknesses in our internal control over financial reporting may be discovered in the future.

Any failure to develop or maintain effective controls could adversely affect the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal control over financial reporting which we may be required to include in our periodic reports we will file with the SEC under Section 404 of the Sarbanes-Oxley Act, harm our operating results, cause us to fail to meet our reporting obligations, or result in a restatement of our prior period financial statements. In the event that we are not able to demonstrate compliance with the Sarbanes-Oxley Act, that our internal control over financial reporting is perceived as inadequate or that we are unable to produce timely or accurate financial statements, investors may lose confidence in our operating results and the price of our common stock could decline. In addition, if we are unable to continue to meet these requirements, we may not be able to remain listed on the Nasdaq Capital Market.

We are not currently required to comply with the SEC rules that implement Section 404 of the Sarbanes-Oxley Act, and are therefore not yet required to make a formal assessment of the effectiveness of our internal control over financial reporting for that purpose. However, we are required to comply with certain of these rules, which require management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of our internal control over financial reporting commencing with our next annual report. This assessment will need to include the disclosure of any material weaknesses in our internal control over financial reporting identified by our management or our independent registered public accounting firm. We are just beginning the costly and challenging process of compiling the system and processing documentation needed to comply with such requirements. We may not be able to complete our evaluation, testing and any required remediation in a timely fashion. During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal control over financial reporting is effective.

Raising additional capital, including through future sales and issuances of our common stock, the exercise of warrants or the exercise of rights to purchase common stock pursuant to our equity incentive plan could result in additional dilution of the percentage ownership of our stockholders, could cause our share price to fall and could restrict our operations.

We expect that significant additional capital will be needed in the future to continue our planned operations, including any potential acquisitions, purchasing of capital equipment, hiring new personnel, and continuing activities as an operating public company. To the extent we seek additional capital through a combination of public and private equity offerings and debt financings, our stockholders may experience substantial dilution. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our existing stockholders may be diluted, and the terms may include liquidation or other preferences that adversely affect the rights of our stockholders. Debt and receivables financings may be coupled with an equity component, such as warrants to purchase shares of our common stock, which could also result in dilution of our existing stockholders’ ownership. The incurrence of indebtedness would result in increased fixed payment obligations and could also result in certain restrictive covenants, such as limitations on our ability to incur additional debt and other operating restrictions that could adversely impact our ability to conduct our business. A failure to obtain adequate funds may cause us to curtail certain operational activities, including sales and marketing, in order to reduce costs and sustain the business, and would have a material adverse effect on our business and financial condition.

Under our 2016 Omnibus Stock Incentive Plan, as amended, or 2016 Plan, we may grant equity awards covering up to 1,754,385 shares of our common stock. As of December 31, 2023, we had granted options to purchase an aggregate of 140,000 shares of common stock and issued 161,347 shares of common stock as stock-based compensation to officers, employees and consultants under the 2016 Plan. Sales of shares issued upon exercise of options or granted under our 2016 Plan may result in material dilution to our existing stockholders, which could cause our share price to fall.

Our issuance of shares of preferred stock could adversely affect the market value of our common stock, dilute the voting power of common stockholders and delay or prevent a change of control.

Our board of directors has the authority to cause us to issue, without any further vote or action by the stockholders, up to 5,000,000 shares of preferred stock in one or more series, to designate the number of shares constituting any series, and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, voting rights, rights and terms of redemption, redemption price or prices and liquidation preferences of such series.

The issuance of shares of preferred stock with dividend or conversion rights, liquidation preferences or other economic terms favorable to the holders of preferred stock could adversely affect the market price for our common stock by making an investment in the common stock less attractive. For example, investors in the common stock may not wish to purchase common stock at a price above the conversion price of a series of convertible preferred stock because the holders of the preferred stock would effectively be entitled to purchase common stock at the lower conversion price causing economic dilution to the holders of common stock.

Further, the issuance of shares of preferred stock with voting rights may adversely affect the voting power of the holders of our other classes of voting stock either by diluting the voting power of our other classes of voting stock if they vote together as a single class, or by giving the holders of any such preferred stock the right to block an action on which they have a separate class vote even if the action were approved by the holders of our other classes of voting stock. The issuance of shares of preferred stock may also have the effect of delaying, deferring or preventing a change in control of our company without further action by the stockholders, even where stockholders are offered a premium for their shares.

Cybersecurity

As filed, 1,973 characters, with its headings, lists and tables. Extracted from the main document; charts and exhibits are in the original on sec.gov.

It is crucial for our business to have precise equipment and open lines of communication. A data breach can disrupt both of these factors, which can result in significant disruptions across of our operations. While we have not had a material cybersecurity incident impact our operations, we face various cyber and other security threats, including attempts to gain unauthorized access to sensitive information and networks; employee threats; virtual and cyber threats to our directors, officers, and employees; threats to the security of our facilities and infrastructure; and threats from terrorist acts or other acts of aggression. Our customers and vendors face similar threats. We utilize internal and external independent controls to monitor and mitigate the risk of these threats, including an outside independent Cybersecurity and Information Technology consultant. We also have a training system in place for our employees.

The impact of potential cybersecurity threats is difficult to predict, but one or more of them could result in the loss of information or capabilities, harm to individuals or property, damage to our reputation, loss of business, regulatory actions, and potential liability, any of which could have a material adverse effect on our financial position, results of operations and/or cash flows. These threats could lead to losses of sensitive information or capabilities, harm to personnel, infrastructure, or products, and/or damage to our reputation as well as our vendor’s ability to perform on our contracts.

Effective incident response involves every part of our organization, including IT teams, legal, technical support, human resources, corporate communications, and business operations. Our Board of Directors and executive management oversee all business, property and affairs of the Company, including cybersecurity risks. Our management keep the members of the Board informed of our business through discussions at Board meetings.

Properties

As filed, 598 characters, with its headings, lists and tables. Extracted from the main document; charts and exhibits are in the original on sec.gov.

Our principal offices are located in Gardena, California, where we lease a 40,000 square feet facility that includes our corporate staff offices, our manufacturing facility, and our research and development center. We also lease a 29,000 square foot manufacturing facility and a 20,000 square foot storage facility near our principal offices. We believe that our current facilities are sufficient to accommodate our anticipated production volumes for the next twelve months. If required, additional office and manufacturing space is available within less than three miles from our present location.

Legal proceedings

As filed, 310 characters, with its headings, lists and tables. Extracted from the main document; charts and exhibits are in the original on sec.gov.

From time to time, we may be involved in general commercial disputes arising in the ordinary course of our business. We are not currently involved in legal proceedings that could reasonably be expected to have material adverse effect on our business, prospects, financial condition or results of our operation.

Management's discussion and analysis

As filed, 34,564 characters, with its headings, lists and tables. Extracted from the main document; charts and exhibits are in the original on sec.gov.

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and the related notes and other financial information included elsewhere in this Annual Report on Form 10-K. In addition to historical information, this discussion and analysis contains forward-looking statements that involve risks, uncertainties, and assumptions. Our actual results may differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those identified below, and those discussed in the section titled “Risk Factors” and elsewhere in this Annual Report on Form 10-K. Our historical results are not necessarily indicative of the results to be expected for any future period, and results for any interim period are not necessarily indicative of the results to be expected for the full year.

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:

DC base power systems. These stationary systems integrate a DC generator and automated controls with remote monitoring, which are typically contained within an environmentally regulated enclosure.
DC hybrid power systems. These systems incorporate lithium-ion batteries (or other advanced battery chemistries) with our proprietary battery management system into our standard DC power systems.
DC solar hybrid power systems. These stationary systems incorporate photovoltaic and other sources of renewable energy into our DC hybrid power system.
Mobile power systems. These stationary systems incorporate photovoltaic and other sources of renewable energy into our DC hybrid power system.

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, 2023 and 2022, 95% and 96%, respectively, of our total net sales were within the telecommunications market. 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. In 2022, our two largest customers represented 66% and 23% 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 2023 and 2022, sales to international customers accounted for 21% and 25% of total revenue, respectively. Sales to military customers during 2023 and 2022 accounted for 3% and 1% of total revenues, respectively. During 2023 and 2022, sales to the marine and other markets accounted for 2% and 3% 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.

We also started deliveries of our Summit Series, 27 kW diesel fuel DC generators to the U.S. 5G telecommunications market. Our US Tier-1 telecommunications customers are in the process of upgrading 15 kW and 20 kW generators to the 27 kW to meet the increased power requirements for 5G.

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.

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. Marine sales interest have increased significantly both domestically and overseas due to the increased performance in comfort and fuel economy. Also, there are increasing restrictions on the use of diesel and gasoline engines in many lakes and waterways making way for our natural gas and propane operated generators. Using natural gas and propane for home and office charging for electric vehicle and forklifts is still a market under development. Same is true for diesel mobile chargers for emergency roadside assistance.

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. 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, 2023 and 2022.

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. Management actively studies trends of warranty claims and takes action to improve product quality and minimize warranty costs. We estimate the actual historical warranty claims coupled with an analysis of unfulfilled claims to record a liability for specific warranty purposes.

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. If the estimated net realizable value is determined to be less than the recorded cost of the inventory, the difference is recognized as a loss in the period in which it occurs. Once inventory has been written down, it creates a new cost basis for inventory that may not subsequently written up.

Stock-Based Compensation. We periodically issue stock-based compensation to officers, directors, employees, and consultants for services rendered. Such issuances vest and expire according to terms established at the issuance date.

Stock-based payments to officers, directors, employees, and for acquiring goods and services from nonemployees, which include grants of employee stock options, are recognized in the financial statements based on their grant date fair values in accordance with ASC 718, Compensation-Stock Compensation. Stock option grants to officers, directors, employees, and consultants, which are generally time vested, are measured at the grant date fair value and depending on the conditions associated with the vesting of the award, compensation cost is recognized on a straight-line or graded basis over the vesting period. Recognition of compensation expense for non-employees is in the same period and manner as if we had paid cash for the services. The fair value of stock options granted is estimated using the Black-Scholes option-pricing model, which uses certain assumptions related to risk-free interest rates, expected volatility, expected life, and future dividends. The assumptions used in the Black-Scholes option pricing model could materially affect compensation expense recorded in future periods.

Effects of Inflation

The impact of inflation and changing prices during 2023 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 2024 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.

Impact of Recent Accounting Pronouncements

See “Note 1 – Organization and Summary of Significant Accounting Policies – Recent Accounting Pronouncements” of the Notes to Financial Statements commencing on page F-7 of this Annual Report on Form 10-K for management’s discussion as to the impact of recent accounting pronouncements.

Financial Performance Summary – Year Ended December 31, 2023

Our net sales for the year ended December 31, 2023, were $15,293, as compared to $16,056 for the year ended December 31, 2022. We reported a net loss of $6,548 for 2023, as compared to net loss of $5,584 for 2022. Our revenues during these periods are primarily due to our telecommunications customers increasing their investments in back-up power generators primarily to support expansion of their network infrastructure.

During the second half of 2023, we experienced a decrease in revenue due to unanticipated rescheduling of approximately $2.0 million in deliveries to our largest telecommunications customers. These orders remain part of our backlog as of December 31, 2023, and are expected to be delivered to customers within the following two quarters.

During 2022 and to a lesser extent in 2023, supply chain constraints affected timely delivery of raw materials required to complete our DC power systems. We believe that the aftermath of the pandemic, inflation, the impacts of war and other recent geopolitical events will be an ongoing challenge for years to come and to adapt will require us to further globalize our vendors, engineering, and customers

During 2023, our international sales were $3,216, or 21% of total net sales, as compared to $3,983, or 25%, during 2022.

Our sales backlog as of December 31, 2023, was $3,862, with 56% of that amount being attributable to our largest U.S. telecommunications customer, 4% represented purchases from other telecommunications customers in the U.S., 31% represented purchases from telecommunications customers outside the U.S., 6% represented purchases from customers in the military markets, and 3% represented purchases from customer in the marine industry. During the first quarter of 2024, the Company received $5,400 in new purchase orders from customers for its DC power systems. Combined with open orders as of April 1, 2024, the Company has a total sales backlog of $7,700, which 40% of the orders are from its largest telecommunications customer in the U.S., 50% from other telecommunications customers, 8% from customers in military markets, and 2% from Marine, EV and other markets. Of the $7,700 in the sales backlog, 36% of the orders are from customers in international markets. The Company expects to complete shipment of these orders within the next six to twelve months.

We plan to continue to expand our customer base in all market segments. We also anticipate that our sales will increase as we overcome supply chain and labor issues. We plan to continue to take proactive steps to manage our operations and mitigate the financial impacts of higher costs and supply chain issues. However, the full impact on our financial and operating performance of the COVID-19 pandemic along with geopolitical factors and increasing inflation concerns 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. See “Risk Factors” commencing on page 16 of this Annual Report on Form 10-K for additional considerations.

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. The columns present the following:

The first two data columns in each table show the absolute results for each period presented.
The columns entitled “Dollar Variance” and “Percentage Variance” shows the change in results, both in dollars and percentages. These two columns show favorable changes as a positive and unfavorable changes as negative. For example, when our net revenues increase from one period to the next, that change is shown as a positive number in both columns. Conversely, when expenses increase from one period to the next, that change is shown as a negative in both columns.
The last two columns in each table show the results for each period as a percentage of net revenues.

Net Sales. Net sales decreased by $763, or 5%, to $15,293 for the year ended December 31, 2023, as compared to $16,056 for the year ended December 31, 2022. The decrease in net sales is attributable to a decrease in deliveries of our DC power generator to our largest telecommunications customer in the U.S. During the second half of 2023, our largest telecommunications customer asked us to postpone deliveries towards the end of the year. As of December 31, 2023, approximately $2.0 million in DC power generators that were scheduled to ship in 2023 remained in our sales backlog.

During 2023, revenue from telecommunications customers accounted for 95% of total net sales, as compared to 96% of total net sales during 2022. Our two largest customers represented 50% and 18% of our total net sales in 2023, as compared to 66% and 23% in 2022. 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 2023 and 2022, sales to international customers accounted for 21% and 25% of total revenue, respectively. Sales to military customers during 2023 and 2022 accounted for 3% and 1% of total revenues, respectively. Sales to marine and other markets during 2023 and 2022 accounted for 2% and 3% 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 increased by $667, or 5%, to $14,598 during 2023, compared to $13,931 during 2022. Cost of sales as a percentage of net sales increased from 86.8% in 2022 to 95.5% in 2023. During the second half of 2023, our largest telecommunications customer requested that we postpone shipments of our DC power generators. This resulted in under-utilization of our production capacity and an increase in factory overhead absorption. Cost of sales during 2023 includes an inventory write-down of $450 to adjust inventory to net realizable value. We believe we will achieve significant reductions in the cost of sales as a percentage of net sales in the upcoming quarters as we ship orders accumulated in our sales backlog.

Gross Profit. We recognized a gross profit of $695 during 2023, as compared to a gross profit of $2,125 during 2022, which represents a decrease in gross profit of $1,430 or 67%. Gross profit as a percentage of net sales decreased to 4.5% in 2023, as compared to 13.2% in 2022. The decrease in gross profit during 2023 was primarily attributable to a decrease in factory overhead absorption resulting from lower sales primarily during the second half of 2023 and an inventory write-down of $450 included in the cost of sales during 2023.

Sales and Marketing Expenses. Sales and marketing expenses decreased $299 to $1,172 during 2023, as compared to $1,471 during 2022. The decrease was attributable to a slight decrease in sales support staff during 2023 as compared the same period in 2022. We plan to increase our sales force and increase our marketing and tradeshow activities in 2024 to support our diversification strategy and expand our customer base in all market segments.

Research and Development Expenses. During 2023, research and development expenses decreased by $238 to $1,222, as compared to $1,460 during 2022. The decrease in 2023 is attributed to a decrease in engineering staff during 2023 as compared to 2022. Our research and development efforts during 2023 primarily focused on developing our new 27 kW power system, new software for our new 4Y Toyota engine control system, mobile EV chargers, and solar hybrid power systems. We continue to search for qualified engineers to join our engineering team and to support our customer diversification efforts.

General and Administrative Expenses. Our general and administrative expenses decreased by $436 to $4,291 during 2023, as compared to $4,727 during 2022. The decrease in general and administrative expenses during 2023 was primarily due to not having stock-based compensation during 2023, as compared to stock-based compensation expense of $515 during 2022, coupled with a slight increase in consulting services, rent, and bank fees during 2023.

Interest and Finance Costs. Our interest expense was $559 in 2023, as compared to $58 in 2022. In 2023, our equipment financing expense decreased by $10, bank fees related to our line of credit with Pinnacle Bank increased by $508.

Net Loss. As a result of the factors identified above, we generated a net loss of $6,548, or ($0.49) per basic and diluted share, for 2023, as compared to net loss of $5,584, or ($0.43) per basic and diluted share, for 2022, an increase loss of $964. The increase in net loss is primarily attributed to a decrease in net sales of $763 due postponement of shipments of our DC power generators during the second half of 2023 as requested by our largest telecommunications customer, an increase in interest expense primarily related to our line of credit with Pinnacle Bank of $508, and an inventory write-down of $450 recorded in the cost of sales during 2023 to adjust inventory to net realizable value.

Liquidity, Capital Resources and Going Concern

Going Concern

Sources of Liquidity

During the year ended December 31, 2023, we funded our operations primarily from cash on hand. As of December 31, 2023, we had working capital of $11,775, as compared to working capital of $17,367 at December 31, 2022. This $5,592 decrease in working capital is primarily attributable to a $338 increase in cash and cash equivalents resulting from net cash of $3,430 used in operating activities, net cash used in investing activities of $194 for the acquisition of new property and equipment, and net cash from financing activities of $3,962 which includes net proceeds of $1,556 from sales of 4,600,000 shares of common stock in December 2023 and net proceeds of $2,354 from our credit facility.

On December 31, 2023, and December 31, 2022, our net trade receivables totaled $1,676 and $2,230, respectively. On December 31, 2023, $1,156 (69%) and $264 (16%) represented the two largest open customer account balances, while $2,006 (90%) represented the largest open customer account balance on December 31, 2022.

At December 31, 2021, we recognized $2,000 related to the ERC for salaries and benefits expenses incurred during 2021 resulting in a refundable tax credit. The ERC assist business owners and their employees by providing an incentive to keep workers on the payroll and eligible businesses received a tax credit for a percentage of each eligible employee’s wage. As of December 31, 2023, the ERC is still being processed by the IRS.

Our available capital resources on December 31, 2023, consisted primarily of $549 in cash and cash equivalents, as compared to $211 as of December 31, 2022. We expect our future capital resources will consist primarily of cash on hand, cash generated by operations, drawdowns on our credit facility with Pinnacle Bank, funds from the ERC, and future debt or equity financings, if any.

Credit Facility

Effective September 30, 2020, we entered into a Loan and Security Agreement, or Loan Agreement, with Pinnacle. The Loan Agreement was amended by the First Modification to Loan and Security Agreement on October 7, 2020. The Loan Agreement’s initial term ended on September 30, 2022. On November 3, 2022, we executed the Second Modification to Loan and Security Agreement with Pinnacle for a two-year term with an expiration date of September 30, 2024.

The Loan Agreement, provides for a revolving credit facility under which Pinnacle may, in its sole discretion upon our request, make advances to us in an amount, subject to certain limitations and adjustments, of up to (a) 85% of the aggregate net face amount of our accounts receivable and other contract rights and receivables, plus (b) the lesser of (i) 35% of the lower of cost or wholesale market value of certain of our inventory or (ii) $2,500. The aggregate amount of the outstanding advances under the revolving credit facility were initially limited to $4,000. On May 25, 2023, we executed the Fourth Modification to the Loan Agreement to amend the amount of available advances under the Loan Agreement such that the aggregate amount of the outstanding advances under the revolving credit facility may not be greater than $6,000 and raised the concentration percentage applicable to certain Tier-1 telecommunication customers from 50% to 75% in the definition of eligible accounts.

On September 5, 2023, the Company entered into a Fifth Modification to the Loan Agreement under which the parties (a) agreed to amend the amount of available advances under the Loan Agreement such that the aggregate amount of the outstanding advances under the revolving credit facility may not be greater than seven and a half million dollars ($7.5 million), (b) extended the standard of eligibility applicable to certain Tier-1 telecommunication customers from ninety (90) days to one hundred twenty (120) days of invoice date in the definition of eligible accounts, (c) increased the inventory advance rate from 35% to 40% of the aggregate eligible inventory value of eligible inventory, and (d) raised the inventory advance limit from two million dollars ($2.0 million) to four million dollars ($4.0 million).

Interest accrues on the daily balance at a rate of 1.25% above the prime rate, or the Standard Interest Rate, but in no event will the Standard Interest Rate be less than 3.75% per annum. Interest on the portion of the daily balance consisting of advances against inventory accrues interest at a rate of 2.25% above the prime rate per annum, or the Inventory Interest Rate, but in no event will the Inventory Interest Rate be less than 4.75% per annum. The Loan Agreement also contains a financial covenant requiring us to attain an effective tangible net worth, defined as our total assets, excluding all intangible assets, less our total liabilities plus loans to us from our officers, stockholders or employees that have been subordinated to our obligations to Pinnacle, greater than $6,000 as determined by Pinnacle as of the end of each fiscal quarter.

We have an outstanding balance of $4,238 under the Loan Agreement at December 31, 2023. As of December 31, 2023, we had availability under the Loan Agreement of $376 and we believe that we are in compliance with the terms and conditions of the Loan Agreement.

Cash Flow

The following table sets forth the significant sources and uses of cash for the periods set forth below (in thousands):

Net Cash Provided By (Used In):	Year Ended December 31, 2023	2022
Operating Activities	$(3,430)	$(6,507)
Investing Activities	$(194)	$(25)
Financing Activities	$3,962	$1,642
Net increase (decrease) in cash	$338	$(4,890)

Operating Activities

Net cash used in operating activities for 2023 was $3,430, as compared to $6,507 for the same period in 2022. This increase in net cash used in 2023 was primarily due to a net loss of $6,548, a decrease in accounts receivable of $554, a decrease in prepaid expenses of $2,174, a decrease in customer deposits of $508, and an increase in inventories of $1,062.

Investing Activities

Net cash used in investing activities for 2023 totaled $194, as compared to $25 for 2022, an increase of $169. The net cash used in investing activities in 2023 was attributable to the purchase of two robotic welders to help improve efficiencies in manufacturing.

Financing Activities

Net cash provided by financing activities totaled $3,962 for 2023, as compared to $1,642 provided by financing activities during 2022, an increase of $2,320. This increase was primarily due to the issuance and sale of 4,60,000 shares of our common stock in a firm commitment underwritten public offering on December 5, 2023. We received net proceeds of approximately $1,556 from the sale of the shares after deducting underwriting discounts and commissions and other offering expenses payable by us. During 2023, we received $2,354 in net proceeds from advances from our credit facility at Pinnacle Bank and repaid $205 on our equipment financing notes payable.

Backlog

As of December 31, 2023, we had a backlog of $3,862. The amount of backlog represents revenue that we anticipate recognizing in the future, as evidenced by purchase orders and other purchase commitments received from customers, but on which work has not yet been initiated or with respect to which work is currently in progress. Backlog at December 31, 2023, was comprised of the following elements: 60% in purchases of DC power systems by telecommunications customers in the U.S., 31% in purchases by telecommunications customers outside the U.S., 6% in purchases in military markets, and 3% in purchases by customers in the marine industry. We believe the majority of our backlog will be shipped within the next twelve months. However, there can be no assurance that we will be successful in fulfilling such orders and commitments in a timely manner or that we will ultimately recognize as revenue the amounts reflected in our backlog. During the first quarter of 2024, the Company received $5,400 in new purchase orders from customers for its DC power systems. Combined with open orders as of April 1, 2024, the Company has a total sales backlog of $7,700, which 40% of the orders are from its largest telecommunications customer in the U.S., 50% from other telecommunications customers, 8% from customers in military markets, and 2% from Marine, EV and other markets. Of the $7,700 in the sales backlog, 36% of the orders are from customers in international markets. The Company expects to complete shipment of these orders within the next six to twelve months.

As filed, 3,887 characters, with its headings, lists and tables. Extracted from the main document; charts and exhibits are in the original on sec.gov.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and our principal financial officer, evaluated, as of the end of the period covered by this Annual Report on Form 10-K, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on that evaluation, our principal executive officer and principal financial officer have concluded that as of December 31, 2023, our disclosure controls and procedures were effective at the reasonable assurance level. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Rule 13a-15(f) under the Exchange Act. Internal control over financial reporting is a process designed under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, (b) our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (c) regarding the prevention or timely detection of the unauthorized acquisition, use or disposition of assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As of December 31, 2023, our management conducted an evaluation of the effectiveness of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013). Based on this evaluation, our management concluded that, as of December 31, 2023, our internal control over financial reporting was effective.

This Annual Report on Form 10-K does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to rules of the Securities and Exchange Commission that permit us to provide only management’s report in this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
