PART I

Item 1. BUSINESS

Company History and Background.

Focus Universal Inc. (the “Company,” “we,” “us,” or “our”) is a Nevada corporation. We are based in the city of Ontario, California, and were incorporated in Nevada in 2012. In December of 2013, we filed an S-1 registration statement that went effective on March 14, 2014. From March 14, 2014, through August 30, 2021, our securities traded on the OTCQB Market. From August 31, 2021, through January 27, 2022, our securities traded on the Nasdaq Capital Market. From January 28, 2022, to September 22, 2024, our securities traded on the Nasdaq Global Market. On September 23, 2024, our securities were transferred for trading to the Nasdaq Capital Market. We hold 28 patents and patents pending in various phases of the patent process.

We operate through multiple subsidiaries, including Perfecular Inc. (“Perfecular”), AVX Design and Integration, Inc. (“AVX”) also doing business as Smart AVX, Focus Universal (Shenzhen) Technology Company LTD (“Focus Shenzhen”), and Lusher, Inc. (“Lusher”).

Perfecular Inc. was founded in September 2009, is headquartered in Ontario, California, and is engaged in designing certain digital sensor products, and sells a broad selection of horticultural sensors and filters in North America and Europe.

AVX, incorporated on June 16, 2000, in the state of California, is an IoT installation and management company specializing in high performance and easy to use audio/video systems, home theaters, lighting control, automation and integration systems for houses, apartments, commercial complexes, and office spaces. AVX also markets and sells our internet of things (IoT) products, such as high-end LED, and live wall panel products and cameras, under the Smart AVX name.

On December 23, 2021, we founded Focus Shenzhen in China for manufacturing procurement expertise and to support research and development activities. Focus Shenzhen is designed to function as a branch office accessing high level research and development support, and the ability to source products and build relationships with Chinese manufacturers.

On April 30, 2024, we founded Lusher Inc. to develop, market, and commercialize an automation financial reporting software called One Touch Financial.

In August of 2024, we decided to discontinue the operations of one of our subsidiaries AT Tech Systems LLC (“AT Tech”). AT Tech specialized in commercial and industrial smart IoT installation projects in areas throughout Southern California.

On November 29, 2024, we held our 2024 annual shareholders meeting, and the shareholders approved of an amendment to the Company’s Articles of Incorporation to increase the number of authorized shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), from 75,000,000 to 150,000,000.

On January 28, 2025, the Company filed a Certificate Change pursuant to Nevada Revised Statutes (“NRS”) 78.209 with the Secretary of State of the State of Nevada to effect a 1-for-10 reverse stock split of the Company’s (i) authorized Common Stock shares and (ii) issued and outstanding Common Stock shares. The reverse stock split became effective on January 31, 2025. All shares of Common Stock, options, warrants and securities convertible or exercisable into Common Stock have been adjusted to give retroactive effect to this reverse stock split for all periods presented. As a result of the reverse split, the Company was authorized to issue 15,000,000 shares of Common Stock.

On September 8, 2025, the Company filed its Second Amendment and Restatement to its Articles of Incorporation to increase the total number of its authorized capital stock to 30,000,000 shares with 25,000,000 shares designated as Common Stock and 5,000,000 shares designated as preferred stock.

On October 20, 2025, the Company filed a Certificate of Designation of Series B Preferred Stock (the “Series B Designation”) that had the effect of designating 15,000 shares of its 5,000,000 authorized shares of preferred stock as Series B Convertible Preferred Stock.

On October 21, 2025, the Company filed a Certificate of Designation of Series A Preferred Stock (the “Series A Designation”) that had the effect of designating 1,000,000 shares of its 5,000,000 authorized shares of preferred stock as Series A Preferred Stock.

On November 17, 2025, the Company increased the total number of authorized capital stock from 30,000,000 shares to 1,100,000,000 shares and designated 1,000,000,000 shares as Common Stock and designated 100,000,000 shares as preferred stock by filing a Third Amendment and Restatement to the Articles of Incorporation.

On December 5, 2025, the Company filed an amendment and restatement to the Series B Designation (the “Amended Series B Designation”) that provided for (i) a fixed floor price, adjusted in the event if reverse splits and/or subdivisions, (ii) the method of calculating the conversion price in the event of a reverse splits and/or subdivisions and (iii) grant of redemption rights to the holders of Series B Convertible Preferred Stock.

On February 9, 2026, the Company effected a reverse stock split of its outstanding common stock on a 1-for-10 basis. No adjustment was made to the Company’s authorized shares of capital stock. As such, the Company’s authorized capital stock consists of 1,000,000,000 shares of Common Stock and 100,000,000 shares of preferred stock with 1,000,000 shares of preferred stock designated as Series A Preferred Stock and 15,000 shares of preferred stock designated as Series B Convertible Preferred Stock.

Our principal executive offices are located at 1515 W Cameron Avenue, Ste. 210, West Covina, CA 91790. Our telephone number is (626) 272-3883, and our website is www.focusuniversal.com. Our website and the information contained therein, or connected thereto, are not intended to be incorporated into this Annual Report.

Our current focus is on commercializing our universal smart technology and financial reporting software. We plan to utilize our universal smart technology for smart meters and automation systems, which will be incorporated into IoT devices. To generate revenues, we will focus on product development, technological upgrades, technical service and customer data collection. We believe this technology has applications in several industries and have completed the development of a system for horticulture applications. Our financial reporting software is an artificial intelligence (AI) enabled software designed to aid accounting professional with the preparation of reports based on financial statements, such reports on Form 10-Q and Form 10-K. We intend to commercialize this product under a software as a service (SaaS) model.

Other than our financial reporting software, the technologies, products and services that we have developed, and are currently developing, we believe will have significant applications in the IoT industry. The IoT refers to the overarching network created by billions of internet-compatible devices and machines that share data and information worldwide. As the sophistication of both hardware and software in the consumer electronics industry skyrockets, an increasing share of the electronic devices produced around the world are manufactured with internet connectivity. Forecasts suggest that by 2030, around 50 billion of these IoT devices will be in use worldwide, creating a massive web of interconnected devices spanning everything from smartphones to kitchen appliances. We believe that IoT will soon reach a critical limit; we do not have enough human labor and natural resources to support its growth. Fifty billion IoT devices will challenge existing resources. To address these challenges, we have segmented our operations and developed the technologies and products described below.

In addition to our universal smart technology and financial reporting software, we are current researching and developing the following:

Device on a Chip

We have developed an innovative “device on a chip” (“DoC”) technology, which combines the required electronic circuits of various integrated circuit components onto a single, integrated chip (“IC”). Our DoC technology works as a single component but is capable of handling entire IoT device functions (excluding sensors and architecture-specific components). Our DoC technology includes both the hardware and software, and decreases the number of interconnections between components. We believe that incorporating our DoC technology into our product offering, will simplify the manufacturing process, lowering our costs and allowing us to achieve a fast time-to-market. Our planned DoC technology allows devices to achieve interoperability with one another and to be interchangeable, both features where traditional IoT devices fall short.

Our research and development suggest that the existing IC integration in IoT devices is mainly focused on hardware-to-hardware integration, not incorporating software solutions. This lack of incorporating software under a common operating system, application software, and extra interface into ICs, limits IC integration to the component level. Software is a critical component in electronics, and the more tightly integrated the software, the better the power and performance. Software also adds an element of flexibility and allows multiple discrete ICs to be integrated into a single IC.

5G Ultra-narrowband Technology

Fifth generation (“5G”) telecommunications networks are expected to revolutionize the digital economy by enabling new applications that depend on ultra-fast communications on an industrial scale. 5G promises to deliver an improved end-user experience by offering new applications and services through gigabit speeds and significantly improved performance and reliability. A World Economic Forum report stated that by 2035 5G networks would contribute $13.2 trillion in economic value globally and generate 22.3 million jobs in the 5G global value chain from direct network investments and residual services. 5G networks and their related applications are expected to add three million jobs and $1.2 trillion to the economy in the U.S.

Though 5G offers a significant increase in speed and bandwidth over previous generation telecommunication networks, its more limited range for high-speed internet will require further infrastructure investments. A 5G network requires spectrum across low, mid, and high spectrum bands to deliver widespread coverage and support a wide range of use cases.

High band, mmWave spectrum is used primarily for urban and dense urban markets. The characteristics of high band, mmWave spectrum is that it is very wide and provides a significant increase in capacity. Because of the greater spectrum width, speed is increased, and transmission latency is reduced. However, the drawback is that high-band spectrum does not propagate over a large coverage area. For example, a 28 GHz mmWave spectrum can only travel 500 feet.

Low-band frequencies can travel long distances and penetrate buildings but can only carry a limited amount of data. High-band frequencies can carry a substantial amount of data, but due to their shorter wavelength, they travel shorter distances and are more susceptible to buildings and trees blocking the signal.

Unlike 4G LTE, which operates on established frequency bands below 6GHz, 5G requires frequencies up to 300GHz. Wireless carriers still need to bid for the costly higher spectrum bands, as they build and roll out their respective 5G networks. Adding the hardware required for 5G networks can significantly increase operating expenses. According to THALES, total global spending on 5G is set to reach $620 billion by 2025.

A typical 5G base station consumes up to twice or more power than a 4G base station. Energy costs increase at higher frequencies due to a need for more antennas and a denser layer of small cells. Edge computing facilities needed to support local processing and new IoT services will also add to overall network power usage.

Our ultra-narrowband (UNB) wireless communication 5G+ technology aims to achieve both low band 5G coverage and 1 Gbps high-band speed because we employ an ultra-narrow spectrum channel (<1kHz) to establish an ultra-long-distance link between the 5G base station and the receiver.

UNB allows for long-range coverage, making it an optimal low-power wide-area network solution for industrial IoT systems. Additionally, its ultra-high power spectral density creates endurance against interference and jamming, which enables the friendly coexistence of UNB on shared frequency bands. The narrower the bandwidth, the fewer occurrences of noise and interference entering the bandwidth. In addition, UNB’s transmission of energy concentrates on ultra-narrowband width, resulting in a very high concentration of power in a very narrow frequency band.

Figure 4. Comparison between Ultra-Narrowband and Broadband

We developed an ultra-narrowband technology that offers a potential alternative and/or complementary solution to the broadband technology used in 5G networks and meets the challenging 5G demands. A comparison of our ultra-narrowband technology with 4G and 5G is illustrated in the table below:

Technology	Bandwidth	No. of subcarriers	Operating Frequency	Speed	Spectral
	MHz		GHz	Mbps	Bits/s/Hz
4G	20	1200	6	4-60	6
5G	100	3276	Up to 300	40-1100	10
UNB (finished)	0.001	1	0.004	4	~4000
UNB (in development)	0.001	1	0.064	64-256	>4000

As shown by the above table, our internal testing shows that our finished ultra-narrowband technology can achieve speeds of 4 Mbps per second at a bandwidth of less than 1000 Hz. The spectral efficiency of our finished technology has reached 4000 bits/sec/Hz. Development work of our ultra-narrowband technology is underway for speeds of 64 Mbps at a bandwidth of 64 MHz with spectral efficiency of over 4000 bits/sec/Hz.

Our internal testing suggests that a single 5G+ subcarrier wave has the potential to provide speeds of 64 to 256 Mbps. Moreover, multiple UNB subcarriers may be combined, which effectively increases bandwidth. Given anticipated data rates of 64 Mbps, we believe only 4 to 16 5G+ subcarrier waves would be needed to achieve the current 5G speeds, and just 40 to 160 5G+ subcarrier waves would be needed to achieve 6G speeds. By contrast, 5G technology requires 3,276 subcarrier waves to achieve its current speeds. Fewer subcarriers translate into cost savings because they are more compact and consume less energy. Our goal is to increase the speed of 5G networks while simultaneously reducing the number of subcarriers.

Our internal testing suggests that to achieve speeds of 1 Gbps, our 5G+ technology would only require bandwidths of 4 to 16 kHz, which is narrow enough to be operated in lower frequency spectrums. This would mean that 5G+ providers would not need to purchase the higher frequency spectrums required by 5G technology. Accordingly, a 5G+ provider would realize significant savings from not having to bid for costly higher spectrum band licenses. Operating in relatively lower frequency spectrum bands, when compared to 5G, also means that 5G+ would have a more extensive coverage area than that of 5G, in many cases three to ten times larger. It would also mean that we could reduce the number of subcarriers and reduce the overall costs of the 5G networks infrastructure.

Ultra-narrowband Power Line Communication (“PLC”) Technology

Our patented PLC is innovative communication technology that enables sending data over existing power cables in the electric grid. Because PLC uses the existing power lines, it does not require substantial new investment for a dedicated wiring infrastructure. Existing power lines already form a distribution network that penetrates every residential, commercial, and industrial property. This makes PLC the most cost-effective, scalable interconnectivity approach for the backbone communication infrastructure required for IoT. PLC allows IoT devices to be plugged into power outlets to establish a connection using the existing electrical wiring, permitting data sharing without the substantial investment and inconvenience of running dedicated network cables.

The power line network was not originally designed to function as a communication channel. The harsh electrical noise present on power lines and variations in equipment and standards make communications over the power grid difficult and present several challenges for data transfer. Signals propagating along the power line are subjected to substantial amounts of noise, attenuation, and distortion. This is why previous attempts at implementing PLC technology resulted in power companies and internet service providers deciding that the technology is not a viable means of delivering data or broadband internet access.

We have successfully developed ultra-narrowband PLC technology that can transfer data through the power grid. According to our internal testing, our ultra-narrowband PLC technology can send and receive data without the customary interference that occurs in standard office and residential environments, achieving speeds of 4 Mbps at a bandwidth of less than 1000 Hz. To test noise interference and disturbance, we utilized six industrial blowers simultaneously when testing, and no significant interference was found. By comparison, a single hair dryer will render our competitors’ legacy PLC technology completely useless. We have completed the development of our 4Mbps PLC modules and the printed circuit board layout. These modules will be used for IoT systems involving over 1,000 sensors.

Natural Integrated Programming Language (“NIPL”)

We have developed a patented “user interface machine auto generation platform” (“UIMAGP”) to replace manual software design. This platform is used to build IoT user interfaces. The natural integrated programming language we have developed is like the language humans use to communicate with each other, which makes it is easy for humans to learn, while still being understood by a machine. The UIMAGP simplifies the process of software programming by saving hundreds of lines of code into a micro code that can be saved to a sensor module. When that sensor module is plugged into a universal smart instrumentations platform (USIP), the user interface specification codes saved to the sensor module is sent to the platform and a universal display, such as a smartphone, a computer, or a display unit. The UIMAGP saved on the universal display automatically generates the user interface within milliseconds. An embedded coding hardware engineer can design sensor module hardware and provide the user interface specification code achieving the hardware-defining software.

The UIMAGP and user interface specification codes work collectively to perform the function of traditional customized software, enabling UIMAGP to be shared by the estimated 20 billion IoT devices worldwide,^[7][8] a feat that to our knowledge, current manual software designs have not been able not achieve.

Universal Smart Instrumentation Hardware and Software Platform (USIP)

USIP is an advanced hardware and software integrated instrumentation platform with a large-scale modular design approach. USIP integrates technologies, including cloud technology, wired and wireless communication technology, software programming, instrumentation technology, artificial intelligence, PLC, sensor networking, and IoT technology into a single platform. This results in circuit designs that we believe are vastly cheaper and faster than those constructed of discrete integrated circuit components designed from scratch.

USIP has primary functionalities and an open architecture capable of incorporating a variety of individual instruments, functions, sensors, and probes from different industries and vendors into a single unit. With USIP, Instruments, sensors, or probes ranging from a few to several hundred or even thousands in any combination from various industries and vendors can share or reuse the same platform. Adding, removing, or changing instruments or sensors is all the platform requires to switch from one type of device to another without revising the software and redesigning the hardware. We believe our USIP will revolutionize the field of instrumentation, measurement, control, and automation.

The development of USIP is closely associated with the development and proliferation of computers and mobile devices that provide the foundation and technical support to the universal smart instrument such as an attractive graphical user touch screen interface, data processing and analysis capabilities, video and audio, cameras, GPS, ubiquitous wireless connectivity, artificial intelligence, cloud-based communications and a diverse number of functions and software available to users that are not contained in traditional instruments. These features embody the advantages of USIP, which are lacking in stand-alone instrument systems. When compared with traditional instrument systems, USIP’s biggest advantage is cost savings. Other distinctive features include universality, interoperability, flexibility, compatibility, upgradeability, expandability, scalability, security, modularity, fast prototyping, reducing inventory, plug-and-play operation, remote accessibility, simplification, standardization, and cloud instrumentation.

We subdivide instruments into a reusable foundation component to the maximum extent possible, architecture-specific components, and sensor modules, which perform traditional instruments’ functions at a fraction of their cost. For most instruments, 90% of the design, parts, and firmware are the same. These parts can be replaced by USIP.

USIP utilizes a computer or a mobile device as its display and control to communicate with a group of sensors, instruments, probes, or controllers manufactured by different vendors in a manner that requires the user to have little or no knowledge of their unique characteristics.

The portable version of USIP, is a universal device called Ubiquitor, is illustrated below. When a blood pressure sensor is plugged into the Ubiquitor, the user interface specification code saved on the blood pressure sensor is sent to the Ubiquitor, and a computer or smartphone will then generate the user interface for the blood pressure device based on the interface specification code saved in the sensor.

Figure 5. A blood pressure sensor is connected to our universal device, which we call the Ubiquitor, and changes our device into a blood pressure measurement instrument.

Similarly, if we remove the blood pressure sensor and connect our Ubiquitor to both a pH sensor and a CO2 sensor, the Ubiquitor changes to a two-sensor device capable of measuring pH and CO2 concentration. Each sensor has its own user interface automatically generated based on the user interface specification code saved in each sensor.

Figure 6. A pH sensor and a CO2 sensor are connected to our universal device, and our device changes into a two-sensor device. A computer or smartphone can also be used for display.

As illustrated below, when a light sensor is also plugged into our Ubiquitor using a three-way splitter, the Ubiquitor becomes a three-sensor device.

Figure 7. A pH sensor, a CO2 sensor, and a light sensor are connected to the Ubiquitor , and the device changes into a three-sensor device. A computer or smartphone can also be used for display.

As illustrated in Figure 8, the Ubiquitor can connect any number of sensors in any combination.
