PART I
Item 1. Business
Overview
Applied Optoelectronics, Inc. (the "Company" or "AOI") is a leading, vertically integrated provider of fiber-optic networking products, primarily for four networking end-markets: internet data center, cable television ("CATV"), telecommunications, ("telecom"), and fiber-to-the-home ("FTTH"). We design and manufacture a range of optical communications products at varying levels of integration, from components, subassemblies and modules to complete turn-key equipment.
In designing products for our customers, we typically begin with the fundamental building blocks of lasers and laser components. From these foundational products, we design and manufacture a wide range of products to meet our customers’ needs and specifications, and such products differ from each other by their end market, intended use and level of integration. We are primarily focused on the higher-performance segments within all four of our target markets, which increasingly demand faster connectivity and innovation.
The four end markets we target are all driven by significant bandwidth demand fueled by the growth of network-connected devices, video traffic, cloud computing and online social networking. Within the internet data center market, we benefit from the increasing use of higher-capacity optical networking technology as a replacement for older, lower-speed optical interconnects, particularly as speeds reach 800 Gbps and above, as well as the movement to open internet data center architectures and the increasing use of in-house equipment design among leading internet companies. Within the CATV market, we benefit from a number of ongoing trends including the move to higher bandwidth networks among CATV service providers, especially the desire by CATV multiple system operators ("MSOs") to increase the return-path bandwidth available to offer to their customers. In the FTTH market, we benefit from continuing passive optical network deployments and system updates among telecom service providers. In the telecom market, we benefit from deployment of new high-speed fiber-optic networks by telecom network operators, including 5G networks.
The CATV market is our most established business, for which we supply a broad array of products, including lasers, transmitters and transceivers, and turn-key equipment. Sales of headend, node and distribution equipment, including amplifiers, have contributed significantly to our revenue in recent years as a result of our ability to meet the needs of CATV equipment vendors who have continued to outsource both the design and manufacturing of this equipment. In 2023, we began offering many of our CATV products directly to MSO customers, under Quantum Bandwidth™ brand name. We made this strategic decision in order to better address the needs of our MSO customers as we believe they are embarking on a complex and lengthy series of network upgrades that will likely require significant innovation from their equipment suppliers. By selling products directly to these customers, we believe that we will be able to address these needs more efficiently and will improve our time to market for these new innovations, which MSOs have indicated will be critical to timely rollout of their planned network upgrades.
The internet data center market is currently our fastest-growing business. Our customers in this market are generally large internet-based ("hyperscale") data center operators, along with equipment suppliers who supply our products along with others to our hyperscale data center operator customers. In both cases, we supply optical transceivers that plug into switches and servers within the data center and allow these network devices to send and receive data over fiber optic cables. The majority of the data center optical transceivers that we sell utilize our own lasers and subassemblies (we refer to the transceivers subassemblies as "light engines"), and we believe that our in-house technology and manufacturing capability for these lasers and subassemblies gives us an advantage over many of our competitors who often lack either development or manufacturing capabilities for these advanced optical modules. In addition, we believe that the significant automation employed in our production process for data center optical modules gives us advantages over our competitors in the ability to scale production rapidly, which is beneficial because the rapid adoption of artificial intelligence ("AI") is fueling a new wave of investment by hyperscale data center operators, as AI computing is very compute and bandwidth intensive.
As the complexity of CATV networks has increased over the years, equipment vendors, many of whom are our customers, have been under pressure to supply a wider variety of increasingly complex equipment to MSOs. In order to meet these demands, many equipment vendors have looked to engage with suppliers like us who have the capability to design and manufacture various network equipment or subassemblies, rather than developing these devices themselves. This outsourcing trend has been a significant contributor to the revenue we derive from the CATV market. We believe that our extensive high-speed optical, mixed-signal semiconductor and mechanical engineering capabilities position us well to continue to benefit from these industry dynamics. Our recent launch of our own branded line of equipment offers an additional growth opportunity for us, enabling us to sell directly to MSOs in certain cases rather than to CATV equipment vendors.
In the telecom market we supply lasers and laser subassemblies as well as transceivers. Our customers in this segment consist mostly of network equipment manufacturers ("NEMs") and other manufacturers of optical transceivers. Our NEM customers manufacture equipment used in telecommunications networks and our transceiver manufacturer customers use our lasers and subassemblies in the manufacture of their optical transceivers. Most of our products in this segment are purchased for use in advanced 5G mobile network deployments.
Our vertically integrated manufacturing model provides us several advantages, including rapid product development, fast response times to customer requests and greater control over product quality and manufacturing costs. We design, manufacture and integrate our own analog and digital lasers using proprietary Molecular Beam Epitaxy ("MBE") and Metal Organic Chemical Vapor Deposition ("MOCVD"), alternative processes for the fabrication of lasers. We believe the use of both processes, and our knowledge of how to combine these processes with others to fabricate lasers is unique in our industry. We manufacture the majority of the laser chips and optical components that are used in our products. The lasers we manufacture are tested extensively to enable reliable operation over time and our devices are often highly tolerant of changes in temperature and humidity, making them well-suited to the CATV, FTTH and 5G markets where networking equipment is often installed outdoors. All of our laser chips are manufactured in our facility in Sugar Land, Texas. We believe that our domestic production capacity for these devices gives us a competitive advantage over many of our competitors, as we believe that many of our customers prefer to source key components from suppliers who have domestic manufacturing capacity.
In 2025, 2024 and 2023, our revenue was $455.7 million, $249.4 million and $217.6 million and our gross margin was 30.0%, 24.8% and 27.1%, respectively. In the years ended December 31, 2025, 2024 and 2023, we had net loss of $38.2 million, $186.7 million and $56.0 million, respectively. At December 31, 2025 and 2024, our accumulated deficits were $493.1 million and $451.9 million, respectively. In 2025, we earned 53.8% of our total revenue from the CATV market and 42.9% of our total revenue from the internet data center market.
In 2025, our key customer in the CATV market was Digicomm. In 2025, 2024, and 2023, Digicomm accounted for 53.1%, 34.1% and 11.3% of our revenue, respectively, and in 2023, ATX Networks accounted for 15.6% of our revenue. In 2025, our key customer in the internet data center market was Microsoft. In 2025, 2024 and 2023, Microsoft accounted for 28.8%, 43.7% and 46.6% of our revenue, respectively, and in 2024, Oracle accounted for 12.4% of our revenue.
Industry Background
During 2025, our four target markets, internet data center, CATV, telecom and FTTH, experienced a significant growth in bandwidth consumption and the corresponding need for network infrastructure improvement to support this growth.
The prevailing trends in our target markets include:
| ‑ |
Trends in the Internet Data Center Market. To support the substantial increase in bandwidth consumption, internet data center operators are increasing the scale of their internet data centers and deploying infrastructure capable of higher data transmission rates. As a result, there is an ongoing transition from the use of copper cable, typically at speeds of up to 1 gigabit per second ("Gbps"), to optical fiber as a transport medium, typically providing speeds from 10 Gbps to 1.6 Tbps. In recent years, a number of leading internet companies have adopted more open internet data center architectures, using a mix of systems and components from a variety of vendors, and in some cases designing their own equipment. For these companies, compatibility of new networking equipment with legacy infrastructure is not as important, and consequently, these companies are more willing to work with non-traditional equipment vendors, which we believe creates an opportunity for optical device vendors. Moreover, transmission speeds have continued to increase among the companies who have previously transitioned from copper-based to fiber-based infrastructure, resulting in opportunities for optical device vendors to supply new optical transceivers capable of operating at these higher data rates. In recent years, supply chain disruptions have become increasingly concerning to our customers. As a result, we believe that our ability to manufacture lasers and other data center products in the US represents a competitive advantage compared with many of our competitors who have most or all of their production outside the US. We have developed a highly-automated production process for many of our data center products, and we believe that this gives us advantages over many of our competitors in terms of ability to scale production rapidly, as well as being able to locate production in favorable geographic locations while maintaining relatively low production costs. Hyperscale data center operators have consistently sought and deployed the most advanced technologies to support the compute and bandwidth needs within their facilities, driving the growth of optical networking within data centers. These operators have adopted more open internet data center architectures and have designed their own networking equipment, both of which use a mix of systems and components from a variety of vendors. We have benefited from these trends over the past several years, and we expect to continue to benefit from them. Recently the hyperscale data center operators have begun to build and upgrade their data centers to support AI, offering us a new growth opportunity. The leading-edge AI applications require significantly more compute capacity and bandwidth, driving the need for faster (800Gbps and higher) and innovative optical networking solutions to support the intra-data center connectivity needs. |
| ‑ | Trends in the CATV Market. Beginning over two decades ago, CATV service providers have invested extensively to support high speed, two-way communications over their networks and we expect that they will continue to do so. In North America, CATV service providers have most recently upgraded their networks with technologies like DOCSIS 3.1, which enables them to offer high speed internet connections to their customers. In order to increase available bandwidth for their customers beyond the bandwidth possible with DOCSIS 3.1, cable MSOs have supported the development of DOCSIS 4.0, which is primarily aimed at increasing the amount of bandwidth available to offer to customers, and also to making the distribution of bandwidth between "forward-path" (i.e. from the MSO office to the customer) and "return-path" (i.e. from the customer to the MSO office) more flexible. In part, enabling the flexible deployment of bandwidth between forward-path and return-path is an effort by MSOs to enable their networks to more effectively scale with consumer demand trends in the future. MSOs like Comcast and Charter have announced plans to spend billions of dollars over the next few years to upgrade to DOCSIS 4.0 network equipment. As one of the early developers of DOCSIS 4.0 equipment, we believe that this represents a significant opportunity for sales of CATV equipment in the next few years. Beginning in 2025, nearly all of our CATV equipment sold meets DOCSIS 4.0 standards. |
| ‑ | Trends in the Telecom Market. The telecom market is composed of customers who deploy wireline optical networks, other than Passive Optical Networks, or PONs, for telecom access networks, including for backhaul of cellular telephone signals. As demand for mobile internet connectivity has increased in recent years, reliable and high-speed optical networks have become increasingly important. In particular, the use of wavelength division multiplexing ("WDM") to expand the capacity of mobile networks has led to increased demand for WDM components (including lasers and transceivers) by telecom equipment manufacturers. In coming years, we believe that the deployment of advanced 5G networks will result in increased demand for optical components, especially those used in connecting between antennas and base stations, as well as for backhaul. |
| ‑ |
Trends in the FTTH Market. The FTTH market generally refers to the PONs that telecom service providers deploy. The most commonly deployed PON technology is Gigabit PON, or GPON, which delivers up to 2.5 Gbps of data, but due to the splitting of the bandwidth among multiple users, the actual bandwidth delivered to an individual subscriber is far less than 2.5 Gbps. One approach that does support true 1 Gbps service to the home is wavelength division multiplexing PON, or WDM-PON, a technology that enables the transmission of multiple wavelengths of data over a single fiber-optic strand. Another approach is XGS-PON, which offers 10 Gbps over a single fiber strand. We also see opportunities for 10 Gbps Ethernet Passive Optical Network ("EPON") and higher data rate PON networks in the future. We have also developed solutions for 25 Gbps PON networks and 50 Gbps PON networks, which we believe will one day be adopted by customers. We have seen trends towards cable television MSOs beginning to deploy PON networks. We see opportunities with these customers particularly given our knowledge and experience in CATV. |
Our Solutions
We experience certain challenges within our target markets, including continuous pressure to innovate and deliver highly integrated products that perform reliably in harsh, demanding environments and to produce high-quality devices in large volumes at competitive prices.
By addressing the challenges in our target markets, we provide the following benefits to our customers:
| ‑ |
Enable customers to deliver innovative products. We leverage our extensive expertise in high-speed optical, mixed-signal semiconductor and mechanical engineering, and MOCVD and our proprietary MBE laser fabrication process to deliver technologically advanced products to our customers. |
| ‑ |
Enhance efficiency and cost effectiveness of our customers’ supply chains. We design and sell products at the level of integration desired by a customer, from components to turn-key equipment, providing our customers a dependable, cost-effective and simplified supply chain. Our relatively more automated production process for certain optical modules also allows us more freedom in locating our manufacturing operations in customer-favored geographic locations while maintaining relatively low labor costs. |
| ‑ |
Deliver high quality, reliable products in high volume. As a vertically integrated supplier, we are able to monitor and maintain quality control throughout the production process, using our internally produced components, where possible, for our final products. With manufacturing facilities in the U.S., Taiwan and China, we can support high volume production and timely delivery for our customers around the world. |
| ‑ |
Provide sophisticated design solutions to our customers. We believe our in-house expertise in both analog and digital optical engineering enables us to design comprehensive solutions that meet many of the different network architectures and protocols used by our customers. |
Our Strengths
Our key competitive strengths include the following:
| ‑ |
Proprietary technological expertise and track record of innovation. We continue to develop innovative products by leveraging our technological expertise, including our proprietary MBE and MOCVD laser fabrication process. |
| ‑ |
Innovative light engine design and manufacturing. High-speed data center interconnect transceivers increasingly rely on multiple parallel optical signals. Our expertise in designing and manufacturing light engines, which combine lasers and photodiodes, and in some cases, driver electronics and/or signal amplifiers, with channel multiplexing and de-multiplexing elements, gives us the ability to quickly develop new products for our data center customers. |
| ‑ |
Proven system design capabilities. We have extensive expertise and proven design capabilities in high-speed optical, mixed-signal semiconductor and mechanical engineering, which we believe position us to take advantage of the continuing shift to outsourced design and manufacturing among CATV equipment vendors. |
| ‑ |
Industry-leading position in the CATV market. We continue to be awarded new design and manufacturing opportunities for CATV components and equipment. We serve a majority of the largest CATV equipment manufacturers in the world and our knowledge of both their requirements and the needs of their customers (the CATV network operators) allows us to access these new opportunities. |
| ‑ |
Vertically integrated, highly automated and geographically distributed manufacturing model. Our vertically integrated design and manufacturing process encompasses various steps from laser design and fabrication to complete optical system design and assembly. Furthermore, we have geographically distributed our manufacturing by strategically locating our operations in the U.S., China and Taiwan to reduce development time and production costs, to better support our customers and to help protect our intellectual property. In addition, we have developed many automated processes used in our production which we believe give us advantages in terms of scalability and control of labor costs. |
Our Strategy
We seek to be the leading global provider of optical components, modules and equipment for each of our four target markets: internet data centers, CATV, telecom and FTTH. Our strategy includes the following key elements:
| ‑ |
Continue to penetrate the internet data center market. In the internet data center market, we primarily target internet data center operators who have adopted an open system architecture—one in which the optical connectivity solutions can be provided by a different vendor than the vendor which provides their servers and switches. |
| ‑ |
Invest in US production capacity for data center products. We believe that our flexible and highly-automated production process gives us a competitive advantage by allowing us to locate production in the U.S., which is desirable to our customers, without dramatically increasing the cost of production by doing so. We intend to enhance this advantage by continuing to aggressively invest in U.S. production. |
| ‑
|
Extend our leadership in CATV networking. We intend to add to our product portfolio in the CATV market following our launch in 2023 of our own branded products to sell directly to MSOs, which we believe offers us further opportunity to enhance our presence as a supplier in the CATV market. |
| ‑ |
Continue to invest in our capabilities, especially our automated module production, and infrastructure. We intend to continue to invest in new products, new technology and our highly-automated production infrastructure and facilities to maintain and strengthen our competitive position. We engage in an active research and development program to develop new products and enhance existing products. |
| ‑ |
Selectively pursue other opportunities that leverage our existing expertise. Our expertise in designing and manufacturing outdoor equipment for the CATV industry positions us well to pursue applications that are also characterized by having varying and demanding environments, including wireless and wireline telecom infrastructure, industrial robotics, aerospace and defense, and oil and gas exploration. |
| ‑ |
Pursue complementary acquisition and strategic alliance opportunities. We evaluate and selectively pursue acquisition opportunities or strategic alliances that we believe will enhance or complement our current product offerings, augment our technology roadmap, or diversify our revenue base. |
Our Technology
We believe that we have technology leadership in four key areas: semiconductor laser manufacturing, electronic technologies that enhance the performance of our lasers, optical hybrid integration and mixed-signal semiconductor design.
| ‑ |
Differentiated semiconductor laser manufacturing. We use a combination of MBE and MOCVD processes in the fabrication of our lasers. We believe that the combination of these two epitaxial processes allows our products to benefit from the advantages afforded by each of these techniques. Among the differentiators of MBE relative to MOCVD fabrication are a lower process temperature and the use of solid phase materials rather than gaseous sources to grow wafers and the growth of more highly strained crystals. These factors contribute to longer operating lives of our lasers, improved laser efficiency and threshold current, and other performance attributes that make them well-suited to our target markets. While we believe that these advantages of MBE are important, MBE does have disadvantages including the inability to use certain dopant materials (for example, Iron), difficulty in certain types of regrowth, and the necessity to maintain complex ultra-high vacuum equipment. By utilizing MOCVD in a portion of our production process, we are able to ameliorate some of these disadvantages. However, the epitaxial and processing steps required in the fabrication of our devices are very complex, with numerous critical steps requiring highly precise control. As a result of some of these challenges, production yields and the performance attributes of laser devices are highly variable and optimizing these characteristics requires numerous enhancements and modifications to standard MBE equipment and the MBE process. To our knowledge, we are unique in incorporating MBE processes in the production of communications lasers in high volume, and believe it would be difficult and time-consuming for other vendors to replicate our production technology. |
| ‑ |
Laser enhancement technology. Certain properties of the semiconductor lasers predominantly used in traditional communications devices, such as chirp and wavelength drift, negatively affect their ability to transmit signals over long fiber distances or prevent them from transmitting signals with acceptable fidelity in certain applications. We have developed laser enhancement circuitry that can correct many of these deficiencies. We believe that our technology will become more essential with wider deployment of higher capacity CATV and FTTH systems, which place more stringent demands on laser performance. |
| ‑ |
Optical hybrid-integration technology. Reducing the size, power consumption and complexity of optical devices is essential for achieving the price and performance targets of our customers. Our ability to integrate multiple optical networking functions into a single device and to co-package multiple devices into smaller form factors helps us meet customer requirements, which we believe can also create new opportunities. For instance, the transmission speed between network elements (switches and servers, for example) within the data center has continued to increase. However, the rate at which this data can be converted from electrical signals to optical signals by laser diodes has not increased at the same pace. Therefore, to achieve data rates of 40 Gbps and above, many customers utilize multiple lower data rate lasers co-packaged together into a single optical module, which we refer to as a light engine. The technology required to cost-effectively and reliably co-package these lasers and the associated electronic control circuitry is complex. Our extensive experience with the processes and the manufacturing technologies required to produce these devices gives us a competitive advantage. |
|
| Similarly, in FTTH and telecom networks, installing new fiber-optic cable is expensive and difficult, and in some situations prohibitively so for a network service provider. As a consequence, network operators seek to maximize the utilization of their installed fiber plant. In long-haul and metropolitan networks, the number of service providers who deployed WDM technology as fiber utilization rose. Fiber utilization in access networks has risen, but the use of WDM technology in the access segment has been problematic due to the relatively high cost and power consumption of the requisite optical devices. We have developed proprietary miniaturized optical packaging, electronic control circuitry and testing algorithms to create a hybrid WDM-PON solution that addresses these historical impediments that we believe will make WDM-PON a cost-effective alternative for deployment. |
| ‑ |
Mixed-signal design. As CATV providers continue to evolve from primarily broadcast-video content providers to a mixture of HD video content together with data-connectivity providers, the networks they utilize to offer these services must evolve as well. Older analog networks are giving way to hybrid networks that incorporate both analog and digital signals. For example, many newer networks are being designed with "digital return-path" capabilities, and certain MSOs have begun to deploy "Remote-PHY" technologies. Both of these technologies involve transporting certain network signals in digital format, and then converting these signals to and from analog signals at various points in the MSO’s network. This combination of analog and digital signaling creates unique design challenges. Our engineers have many years of experience in developing equipment, modules and components that are well suited to these sorts of mixed-signal architectures. We believe that having deep experience in both digital and analog signaling allows us to offer superior solutions to our customers, compared with companies who have expertise in only one of these signal types. |
Our Products
Our products include an array of optical communications solutions at varying levels of integration. We commonly begin from the fundamental building blocks of lasers and laser components. From these foundational products, we design and manufacture a wide range of products from optical modules to complete turn-key equipment. We design our products to target customers in our identified markets to meet their needs and specifications.
Our components often incorporate one or more of our optical laser chips inside a precision housing that provides mechanical protection as well as standardized electrical contacts. More complex optical components may also include optical filters (for example, for use in WDM) or other optical elements by which optical signals are routed internally within the component. These more advanced components may also include coolers, heaters and sensors that allow the temperature of the laser chip to be measured and controlled. We manufacture the majority of the laser chips and optical components that are used in our own products.
At the next level of integration, our module or sub-assembly products typically contain one or more of our optical components and some additional control circuitry. Examples of modules include our transceiver line primarily used in internet data center markets, telecom markets, and FTTH markets.
At the highest level of integration and complexity, our equipment products typically contain one or more optical components, modules and additional electronic control circuitry required to enable these subsystems to operate independently. For example, our CATV transmitter equipment requires utilization of our optical components and assembly onto a circuit board and to an external housing. Examples of equipment include our CATV transmitter and CATV nodes. Notwithstanding our expertise in optical transmission equipment, in some cases we utilize our technical expertise in radio frequency ("RF") design to develop products that do not have significant optical technology incorporated, for example our CATV amplifier products which serve to amplify the RF signals in the coaxial-cable portion of an MSO's network do not incorporate optics, but do rely on advanced mixed-signal RF and digital electronic design as well as software and firmware which we develop in house.
Research and Development
Intellectual Property
We rely on a combination of patent, copyright, trademark, trade secret laws and unfair competition laws, as well as confidentiality and licensing arrangements, to establish and protect our intellectual property. We employ various methods to protect these intellectual property rights, including maintaining a technological infrastructure with significant security measures, limiting disclosure and restricting access to only those individuals with an operational need for such information, and having employees, consultants and suppliers execute confidentiality agreements with us. While we expect our intellectual property to provide competitive advantages, we also find meaningful value from unpatented proprietary process knowledge, know-how and trade secrets.
Patents
As of December 31, 2025, we owned a total of 199 U.S. issued patents, 140 patents issued in China and Taiwan and 10 patents issued in Europe, plus a number of pending U.S. and foreign/international patent applications. Our issued U.S. and foreign patents will expire between 2026 and 2046. While our patents are an important element of our success, our business as a whole is not dependent on any one patent or group of patents. We do not anticipate any material effect on our business due to any patents expiring in 2025, and we continue to obtain new patents through our ongoing research and development.
Our portfolio of patents and patent applications covers several different technology families including:
| ‑ | laser structure and design; |
| ‑ | optical signal conditioning and laser control; |
| ‑ |
laser fabrication; |
| ‑ |
photodiode and optical receiver design and fabrication; |
| ‑ |
optical device and module designs; |
| ‑ |
optical device packaging equipment and techniques; |
| ‑ |
optical network enhancements; and |
| - | CATV networking technologies. |

Manufacturing and Operations
We have three manufacturing sites: Sugar Land, Texas, Ningbo, China and Taipei, Taiwan. Our research and development functions are generally partnered with our manufacturing locations, and we have an additional research and development facility in Duluth, Georgia. In our Sugar Land facility, we manufacture laser chips (utilizing our MBE and MOCVD processes), subassemblies and components. The subassemblies are used in the manufacture of components by our other manufacturing facilities or sold to third parties as modules. We manufacture our laser chips only within our Sugar Land facility, where our laser design team is located. In our Taiwan location, which comprises several buildings in close proximity to each other, we manufacture optical components, such as our butterfly lasers, which incorporate laser chips, subassemblies and components manufactured within our Sugar Land facility. In addition, in our Taiwan location, we manufacture transceivers for the internet data center, telecom, FTTH and other markets and we also manufacture CATV outdoor equipment including amplifiers. In our China facility, we take advantage of lower labor costs and manufacture certain more labor intensive components and optical equipment systems, such as optical subassemblies and transceivers for the CATV transmitters (at the headend), internet data center market, and CATV outdoor equipment. Each manufacturing facility conducts testing on the components, modules or subsystems it manufactures and each facility is certified to ISO 9001:2015 and ISO 14001:2015.
We sell our products to customers worldwide, and in addition to these external customer sales many of our products are used internally in the production of transceivers and equipment that we manufacture. With a vertically integrated manufacturing process, we produce many of our own laser chips and other parts required to manufacture our optical components. Through this model, we are able to reduce development time and product costs as well as actively monitor and control product quality. We incorporate our own components into our transceivers, subsystems and equipment products wherever possible. In instances where we do not produce components ourselves, we source them from external suppliers and regularly evaluate these relationships in an attempt to reduce risk and lower cost.
We depend on a limited number of suppliers, including in some cases our own internal supply, for certain raw materials and components used in our products. We regularly review our vendor relationships in an attempt to mitigate risks and lower costs, especially where we depend on one or two vendors for critical components or raw materials. While maintaining inventories that we believe are sufficient to meet our near-term needs, we strive not to carry significant inventories of externally sourced raw materials. Accordingly, we maintain ongoing communications with our vendors in order to help prevent any interruptions in supply, and have implemented a supply-chain management program to maintain quality and lower purchase prices through standardized purchasing efficiencies and design requirements.
Sources of Raw Materials
Customers
Our customers are primarily internet data center operators, CATV and telecom equipment manufacturers, and internet service providers. We generally employ a direct sales model in North America and in the rest of the world we use both direct and indirect sales channels. In 2025, 2024 and 2023, we obtained 44.7%, 64.4% and 88.6% of our revenue, respectively, through our direct sales efforts and the remainder of our revenue through our indirect sales channels. Our sales channel partners provide logistical services and day-to-day customer support. Where we sell through an indirect sales channel, we work with the end customer to establish technological specifications for our products. We also from time to time offer design or manufacturing services to customers to assist them in more effectively using our products and realizing time-to-market advantages.
We have taken several actions to increase the diversity of our customer base. These actions include hiring sales staff to improve our ability to serve new customers and the introduction of new products that we believe will appeal to new customers. Furthermore, we have developed additional original design manufacturer, or ODM, relationships with customers in each of our target markets which should enable us to diversify our revenue base.
In 2025, the largest customer who contributed most to our internet data center revenue was Microsoft. In 2025, our largest CATV customer was Digicomm. In 2025, revenue from CATV market, the internet data center market, telecom market, FTTH and other markets provided 53.8%, 42.9%, 3.0% and 0.3% of our revenue, respectively, compared to 35.2%, 59.5%, 4.4% and 0.9%, respectively, in 2024.
In our telecom market, we manufacture and sell optical products which include transceivers designed to transmit signals used in 5th Generation ("5G") mobile networks, and various products targeted at the metro-scale telecom networking market. We have various other products designed for diverse applications, both inside and outside of communications technology, which generally are derivatives of products developed for our four target markets.
We support our sales efforts by attendance at industry trade shows, technical conferences and other promotional efforts. These efforts are aimed at attracting new customers and enhancing our existing customer relationships.
Backlog
We generally make sales pursuant to short-term purchase orders without deposits and subject to rescheduling, revision or cancellation on short notice. We accordingly believe that purchase orders are not an accurate indicator of our future sales and any backlog of purchase orders is not a reliable indicator of our future revenue.
Competition
The optical networking market is intensely competitive. Because of the broad nature of our product offerings, we do not believe that we face a single major competitor across all of our markets. We do, however, experience intense competition in each product area from a number of manufacturers and we anticipate that competition will increase. Our major competitors in one or more of our markets include Coherent Corporation, Eoptolink Technology Inc., Ltd., Foxconn Interconnect Technology Ltd., InnoLight Technology (Suzhou) Ltd., Intel Corporation, Lumentum Holdings, Inc., Mitsubishi, Molex, LLC, Source Photonics, Inc. and Sumitomo Electric Industries, Ltd.
Many of our competitors are larger than we are and have significantly greater financial, marketing and other resources.
In addition, several of our competitors have large market capitalizations or cash reserves and are much better positioned to acquire other companies to gain new technologies or products that may displace our products. Network equipment providers, who are our customers, and network service providers, who are supplied by our customers, may decide to manufacture the optical subsystems incorporated into their network systems in-house. We also encounter potential customers that, because of existing relationships, are committed to the products offered by these competitors.
We believe the principal competitive factors in our target markets include the following:
| ‑ |
use of internally manufactured components; |
| ‑ |
product breadth and functionality; |
| ‑ |
timing and pace of new product development; |
| ‑ |
breadth of customer base; |
| ‑ |
technological expertise; |
| ‑ |
reliability of products; |
| ‑ |
product pricing; and |
| ‑ |
manufacturing efficiency. |
We believe that we compete favorably with respect to the above factors based on our MBE and MOCVD processes, our vertically integrated model, the performance and reliability of our product offerings, and our technical expertise in light engine design and manufacture.
Seasonality
See Part II, Item 7, "Management’s Discussion and Analysis of Financial Condition and Results of Operations—Seasonality," regarding seasonality of certain of the Company’s products.
Human Capital
Employees
As of December 31, 2025, we employed 4,691 full-time employees, of which 69 held Ph.D. degrees in a science or engineering field. Of our employees, 548 are located in the U.S., 1,262 are located in Taiwan and 2,881 are located in China.
As of December 31, 2025, none of our employees are represented by any collective bargaining agreement, but certain employees of our China subsidiary are members of a trade union. We have never suffered any work stoppage as a result of an employment related strike or any employee related dispute and believe that we have satisfactory relations with our employees.
Employee Engagement, Development and Career Planning
Our business results depend in part on our ability to successfully manage our human capital resources, including attracting, identifying, and retaining key talent. Factors that may affect our ability to attract and retain qualified employees include employee morale, our reputation, competition from other employers, and availability of qualified individuals. We believe our commitment to our human capital resources is an important component of our mission to deliver superior products to our customers. We provide all employees with the opportunity to share their opinions in open dialogues with our human resources department and senior management. In the past, we have conducted confidential surveys of select workforce members to measure engagement. The results are discussed with senior leadership and managers. We provide all employees a wide range of professional development experiences, both formal and informal. We offer our highest level employees/executives/VPs leadership development programs as part of our talent and succession planning process. Also, we have development programs for managers and supervisors and learning opportunities for all employees. We provide access to learning platforms so employees can access resources to support their career aspirations and advance their skills.
Employee Safety
The safety of our employees is a paramount value for us. We provide mandatory safety trainings in our production facilities, which are designed to focus on empowering our employees with the knowledge and tools they need to make safe choices and to mitigate risks. Supervisors complete safety management courses as well.
Compensation, Benefits and Wellness
We offer fair, competitive compensation and benefits that support our employees’ overall wellness. Further, the health and wellness of our employees are critical to our success. We provide our employees with access to a variety of innovative, flexible and convenient health and wellness programs. Such programs are designed to support employees' physical and mental health by providing tools and resources to help them improve or maintain their health status and encourage engagement in healthy behaviors. We offer financial education and financial wellness tools and resources to help employees reach their personal financial goals. Additionally, we provide robust compensation and benefits through internal and external benchmarking.
Governmental Regulations
Our research and development and manufacturing operations and our products are subject to a variety of federal, state, local and foreign environmental, health and safety laws and regulations, including those governing discharges of pollutants to air and water, the use, storage, handling and disposal of hazardous materials and solid wastes, employee health and safety, and the hazardous material content in our products. To date, costs and accruals incurred to comply with these governmental regulations have not been material to our capital expenditures, results of operations, and competitive position. Our environmental management systems in our facilities in Sugar Land, Texas, Ningbo, China and Taipei, Taiwan are all certified to meet the requirements of ISO14001:2015. However, there can be no assurance that violations of applicable laws at any of our facilities will not occur in the future as a result of human error, accident, equipment failure or other causes. We use, store and dispose of hazardous materials and solid wastes in our manufacturing operations and hazardous materials are present in our products. We incur costs to comply with environmental, health and safety requirements, and any failure to comply, or the identification of contamination for which we are found liable, could cause us to incur substantial costs, including cleanup costs, natural resource damages, monetary fines, or administrative, civil or criminal penalties, and subject us to property damage and personal injury claims, and result in injunctive relief including the suspension of production, alteration or upgrades of our manufacturing processes, redesign of our products, or curtailment of sales, and could result in adverse publicity. Liability under environmental, health and safety laws can be joint and several and without regard to fault or negligence. For example, pursuant to environmental laws and regulations, including but not limited to the Comprehensive Environmental Response Compensation and Liability Act, or CERCLA, we may be liable for the full amount of any remediation-related costs at properties we currently own or operate or formerly owned, such as our currently owned Sugar Land, Texas facility, or at properties at which we previously operated, as well as at properties we will own or operate in the future, and properties to which we have sent hazardous substances, whether or not we caused the contamination.
Environment
We are committed to maintaining compliance with all environmental laws applicable to our operations, products, and services and to reducing our environmental impact across our business. Our operations and many of our products are subject to various federal, state, local, and foreign regulations that have been adopted with respect to the environment, such as the Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment; Registration, Evaluation, Authorization, and Restriction of Chemicals; and Substances of Concern In Products, regulations adopted by the European Union, or EU.
| – |
Obtain at least 20% of the energy used in our operations from renewable sources |
| – |
Properly recycle waste materials including paper, electronic components, glass and batteries |
| – |
Reduce our generation of hazardous waste by at least 10% over the five year period beginning in 2024 |
In order to meet these goals, we maintain an Integrated Environmental and Safety Management System.
We expect that our operations and products will be affected by new environmental requirements on an ongoing basis. Environmental, health and safety requirements have become more stringent over time, and changes to existing requirements could restrict our ability to expand our facilities, require us to acquire costly pollution control equipment, require us to obtain additional permits for our activities, or cause us to incur other significant expenses or to modify our manufacturing processes or the hazardous material content of our products. Identification of presently unidentified environmental conditions, more vigorous enforcement by a governmental authority, enactment of more stringent legal requirements or other unanticipated events could give rise to adverse publicity, restrict our operations, affect the design or marketability of our products or otherwise cause us to incur material environmental costs or delays in planned activities.
We face increasing complexity in our product design and procurement operations as we adjust to new and upcoming requirements relating to the materials composition of our products. Some jurisdictions in which our products are sold have enacted requirements regarding the hazardous material content of certain products. For example, member states of the European Union and China are among a growing number of jurisdictions that have placed restrictions on the use of lead, among other chemicals, in electronic products, which affect the composition and packaging of our products. The passage of such requirements in additional jurisdictions, or the tightening of standards or elimination of certain exemptions in jurisdictions where our products are already subject to such requirements, could cause us to incur significant expenditures to make our products compliant with new requirements, or could limit the markets into which we may sell our products. Other governmental regulations may require us to reengineer our products to use components that are more environmentally compatible, resulting in additional costs to us.
Climate Change and Sustainability
Export Controls
The Bureau of Industry and Security (BIS) of the U.S. Department of Commerce is responsible for regulating the export of most commercial items that are classified as dual-use goods that may have both commercial and military applications. Our products are primarily classified under Export Control Classification Numbers ("ECCN") 5A991, 6A995, and EAR99. Export Control Classification requirements are dependent upon an item’s technical characteristics, the destination, the end-use, the end-user, and the activities of the end-user. Should the ECCN change, then the export of our products to certain countries would be restricted. However, we currently do not export our products to any countries on the restricted list, and therefore a change in the ECCN would not materially impact our business.
Additional information concerning regulatory compliance and a discussion of the risks associated with governmental regulations that may materially impact us is described more fully under the heading "Risk Factors" in this Form 10-K.

Risks Related to Operating Our Business
Significant capital investments in U.S. manufacturing and automation, including investments intended to support artificial intelligence ("AI")-related demand, may not achieve expected returns and could adversely affect our business, financial condition, and results of operations.
We are planning and, in some cases, have already commenced substantial capital investments to expand and modernize our U.S. manufacturing footprint and to increase automation across our operations.
We are dependent on our key customers for a significant portion of our revenue and the loss of, or a significant reduction in orders from, any of our key customers would adversely impact our revenue and results of operations.
We generate much of our revenue from a limited number of customers. For each year ended 2025, 2024 and 2023, our top ten customers represented 96.6%, 95% and 92.7% of our revenue, respectively. In 2025, Digicomm represented 53.1% of our revenue and Microsoft represented 28.8% of our revenue. As a result, the loss of, or a significant reduction in orders from any of our key customers would materially and adversely affect our revenue and results of operations. We typically do not have long-term contracts with our customers and instead rely on recurring purchase orders. However, many of our current revenue expectations and forecasts reflect significant anticipated orders from a limited number of key customers. If our key customers do not continue to purchase our existing products or fail to purchase additional products from us, our revenue would decline and our results of operations would be adversely affected.
Adverse events affecting our key customers could also negatively affect our ability to retain their business and obtain new purchase orders, which could adversely affect our revenue and results of operations. For example, in recent years, there has been consolidation among various network equipment manufacturers and this trend is expected to continue. We are unable to predict the impact that industry consolidation would have on our existing or potential customers. We may not be able to offset any potential decline in revenue arising from the consolidation of our existing customers with revenue from new customers or additional revenue from the merged company.
Customer demand is difficult to forecast accurately and, as a result, we may be unable to match production with customer demand.
We make planning and spending decisions, including determining the levels of business that we will seek and accept, production schedules, component procurement commitments, personnel needs and other resource requirements, based on our estimates of product demand and customer requirements. Our products are typically purchased pursuant to individual purchase orders. While our customers may provide us with their demand forecasts, they are typically not contractually committed to buy any quantity of products beyond firm purchase orders. Furthermore, many of our customers may increase, decrease, cancel or delay purchase orders already in place without significant penalty. The short-term nature of commitments by our customers and the possibility of unexpected changes in demand for their products reduce our ability to accurately estimate future customer requirements. On occasion, customers may require rapid increases in production, which can strain our resources, cause our manufacturing to be negatively impacted by materials shortages, necessitate more onerous procurement commitments and reduce our gross margin. We may not have sufficient capacity at any given time to meet the volume demands of our customers, or one or more of our suppliers may not have sufficient capacity at any given time to meet our volume demands. If any of our major customers decrease, stop or delay purchasing our products for any reason, we will likely have excess manufacturing capacity or inventory and our business and results of operations would be harmed.
If our customers do not qualify our products for use on a timely basis, our results of operations may suffer.
Prior to the sale of new products, our customers typically require us to "qualify" our products for use in their applications. At the successful completion of this qualification process, we refer to the resulting sales opportunity as a "design win". Additionally, new customers often audit our manufacturing facilities and perform other evaluations during this qualification process. The qualification process involves product sampling and reliability testing and collaboration with our product management and engineering teams in the design and manufacturing stages. If we are unable to accurately predict the amount of time required to qualify our products with customers, or are unable to qualify our products with certain customers at all, then our ability to generate revenue could be delayed or our revenue would be lower than expected and we may not be able to recover the costs associated with the qualification process or with our product development efforts, which would have an adverse effect on our results of operations.
In addition, due to rapid technological changes in our markets, a customer may cancel or modify a design project before we have qualified our product or begun volume manufacturing of a qualified product. It is unlikely that we would be able to recover the expenses for cancelled or unutilized custom design projects. Some of these unrecoverable expenses for cancelled or unutilized custom design projects may be significant. It is difficult to predict with any certainty whether our customers will delay or terminate product qualification or the frequency with which customers will cancel or modify their projects, but any such delay, cancellation or modification would have a negative effect on our results of operations.
Our ability to successfully qualify and scale capacity for new technologies and products is important to our ability to grow our business and market presence, and we may invest a significant amount to scale our capacity to meet potential demand from customers for our new technologies and products. If we are unable to qualify and sell any of our new products in volume, on time, or at all, our results of operations may be adversely affected.
Technology adoption cycles impact our business.
In each of our markets, technology standards influence customer purchasing patterns and vendor selection. Network operators deploy the next generation of technology at different times and typically reduce or stop their purchase of the trailing generation of equipment in advance of their deployment of the next generation. Our revenue from sales of the trailing generation products may fall rapidly, or at an uneven rate, and the prices at which we can sell the trailing generation products may decline. If we do not effectively manage our inventory, we may have an excess of inventory that we may not be able to participate in vendor selection processes of operators and their equipment providers for the next generation of technology deployment, which would reduce our future revenue potential.
We must continually develop successful new products and enhance existing products, and if we fail to do so or if our release of new or enhanced products is delayed, our business may be harmed.
The markets for our products are characterized by frequent new product introductions, changes in customer requirements and evolving industry standards, all with an underlying pressure to reduce cost and meet stringent reliability and qualification requirements. Our future performance will depend on our successful development, introduction and market acceptance of new and enhanced products that address these challenges. If we are unable to make our new or enhanced products commercially available on a timely basis, we may lose existing and potential customers and our financial results would suffer.
In addition, due to the costs and length of research, development and manufacturing process cycles, we may not recognize revenue from new products until long after such expenditures, if at all, and our margins may decrease if our costs are higher than expected, adversely affecting our financial condition and results of operations.
Although the length of our product development cycle varies widely by product and customer, it may take 18 months or longer before we receive our first order. As a result, we may incur significant expenses long before customers accept and purchase our products.
Product development delays may result from numerous factors, including:
| ‑ |
modification of product specifications and customer requirements; |
| ‑ |
unanticipated engineering complexities; |
| ‑ |
difficulties in reallocating engineering resources and overcoming resource limitations; and |
| ‑ |
rapidly changing technology or competitive product requirements. |
The introduction of new products by us or our competitors and other changes in our customer’s demands could result in a slowdown in demand for our existing products and could result in a write-down in the value of our inventory. We have in the past experienced periodic fluctuations in demand for existing products and delays in new product development, and such fluctuations will likely occur in the future. To the extent we fail to qualify our products and obtain their approval for use, which we refer to as a design win, or experience product development delays for any reason, our competitive position would be adversely affected and our ability to grow our revenue would be impaired.
Furthermore, our ability to enter a market with new products in a timely manner can be critical to our success because it is difficult to displace an existing supplier for a particular type of product once a customer has chosen a supplier, even if a later-to-market product provides better performance or cost efficiency.
The development of new, technologically advanced products is a complex and uncertain process requiring frequent innovation, highly-skilled engineering and development personnel and significant capital, as well as the accurate anticipation of technological and market trends. We cannot assure you that we will be able to identify, develop, manufacture, market or support new or enhanced products successfully or on a timely basis. Further, we cannot assure you that our new products will gain market acceptance or that we will be able to respond effectively to product introductions by competitors, technological changes or emerging industry standards. We also may not be able to develop the underlying core technologies necessary to create new products and enhancements, license these technologies from third parties, or remain competitive in our markets.
Adverse global economic conditions could have a negative effect on our business, results of operations and financial condition and liquidity.
A general slowdown in the global economy or in a particular region or industry, other unfavorable changes in economic conditions, such as inflation, higher interest rates, tightening of the credit markets, recession or slowing growth, or an increase in trade tensions with U.S. trading partners could negatively impact our business, financial condition and liquidity. Adverse global economic conditions have from time to time caused or exacerbated significant slowdowns in the industries and markets in which we operate, which have adversely affected our business and results of operations. Macroeconomic weakness and uncertainty also make it more difficult for us to accurately forecast operating results, and may make it more difficult to raise or refinance debt. An escalation of trade tensions between the U.S. and China has resulted in trade restrictions, increased protectionism and increased tariffs that harm our ability to participate in Chinese markets or compete effectively with Chinese companies. Sustained uncertainty about, or worsening of, current global economic conditions and further escalation of trade tensions between the U.S. and its trading partners, especially China, and the decoupling of the U.S. and China economies, could result in a global economic slowdown and long-term changes to global trade. Such events may also (i) cause our customers and consumers to reduce, delay or forgo technology spending, (ii) result in customers sourcing products from other suppliers not subject to such restrictions or tariffs, (iii) lead to the insolvency or consolidation of key suppliers and customers, and (iv) intensify pricing pressures. Any or all of these factors could negatively affect demand for our products and our business, financial condition and results of operations.
Our revenues, growth rates and operating results are likely to fluctuate significantly as a result of factors that are outside our control, which could adversely impact our operating results.
Our revenues, growth rates and operating results are likely to fluctuate significantly in the future as a result of factors that are outside our control. We may not achieve similar revenues, growth rates or operating results in future periods. Our revenues, growth rates and operating results for any prior quarterly or annual period should not be relied upon as any indication of our future revenues, growth rates or operating results. The timing of order placement, size of orders and satisfaction of contractual customer acceptance criteria, changes in the pricing of our products due to competitive pressures as well as order or shipment delays or deferrals, with respect to our products, may cause material fluctuations in revenues. Our lengthy sales cycle, which may extend to more than one year, may cause our revenues and operating results to vary from period to period and it may be difficult to predict the timing and amount of any variation. Delays or deferrals in purchasing decisions by our customers may increase as we develop new or enhanced products for existing and new markets, including automotive and biotechnology markets. Our current and anticipated future dependence on a small number of customers increases the revenue impact of each such customer’s decision to delay or defer purchases from us, or decision not to purchase products from us. Our expense levels in the future will be based, in large part, on our expectations regarding future revenue sources and, as a result, operating results for any quarterly period in which anticipated material orders fail to occur, or are delayed or deferred, could be significantly harmed.
Given the high fixed costs associated with our vertically integrated business, a reduction in demand for our products will likely adversely impact our gross profits and our results of operations.
We have a high fixed cost base due to our vertically integrated business model, including the fact that 4,116 of our employees as of December 31, 2025 were employed in manufacturing and research and development operations. We may not be able to adjust these fixed costs quickly to adapt to rapidly changing market conditions. Our gross profit and gross margin are greatly affected by our sales volume and volatility on a quarterly basis and the corresponding absorption of fixed manufacturing overhead expenses. In addition, because we are a vertically integrated manufacturer, insufficient demand for our products may subject us to the risk of high inventory carrying costs and increased inventory obsolescence. Given our vertical integration, the rate at which we turn inventory has historically been low when compared to our cost of sales. We do not expect this to change significantly in the future and believe that we will have to maintain a relatively high level of inventory compared to our cost of sales. As a result, we continue to expect to have a significant amount of working capital invested in inventory. We may be required to write down inventory costs in the future and our high inventory costs may have an adverse effect on our gross profits and our results of operations.
Changes in United States tariff and import/export regulations may have a negative effect on our business.
During the year ended December 31, 2025, the United States has imposed, and may continue to impose, significant tariffs and other trade restrictions on imported goods. In February 2026, the U.S. Supreme Court held that tariffs imposed under the International Emergency Economic Powers Act ("IEEPA") were unlawful, and U.S. Customs and Border Protection subsequently announced that IEEPA-based tariff provisions would be terminated effective February 24, 2026. However, tariffs imposed under other authorities, including Section 232 of the Trade Expansion Act of 1962 and Section 301 of the Trade Act of 1974, remain in effect, and the U.S. government has indicted that it may pursue additional or replacement tariffs under alternative legal authorities, including temporary measures under Section 122 of the Trade Act of 1974.
As a result, the tariff environment remains highly uncertain and subject to rapid change. Further changes in tariff rates, product coverage, enforcement, exclusions, customs guidance, or related trade measures, as well as litigation outcomes and any governmental responses to such outcomes, could increase our costs, disrupt our supply chain, affect customer demand, reduce our margins, and otherwise adversely affect our business, results of operations and financial condition. In addition, uncertainty regarding the availability, timing and amount of any refunds or other relief relating to previously paid duties may affect our cash flows and results in future periods. We cannot predict the scope, timing or ultimate impact of these developments.
President Trump has directed various federal agencies to further evaluate key aspects of U.S. trade policy and there has been ongoing discussion and commentary regarding potential significant changes to U.S. trade policies, treaties and tariffs. There continues to exist significant uncertainty about the future relationship between the U.S. and other countries with respect to such trade policies, treaties and tariffs. These developments, or the perception that any of them could occur, may have a material adverse effect on global economic conditions, the stability of global financial markets, and may significantly reduce global trade and, in particular, trade between impacted nations and the U.S. Any of these factors could depress economic activity and restrict our access to suppliers or customers and have a material adverse effect on our business, financial condition and results of operations.
Increasing costs and shifts in product mix may adversely impact our gross margins.
Our gross margins on individual products and among products fluctuate over each product’s life cycle. Our overall gross margins have fluctuated from period to period as a result of shifts in product mix, the introduction of new products, decreases in average selling prices and our ability to reduce product costs, and these fluctuations are expected to continue in the future. We may not be able to accurately predict our product mix from period to period, and as a result we may not be able to forecast accurately our overall gross margins. The rate of increase in our costs and expenses may exceed the rate of increase in our revenue, either of which would materially and adversely affect our business, our results of operations and our financial condition.
Our financial results may vary significantly from quarter-to-quarter due to a number of factors, which may lead to volatility in our stock price.
Our quarterly revenue and operating results have varied in the past and will likely continue to vary significantly from quarter-to-quarter. This variability may lead to volatility in our stock price as research analysts and investors respond to these quarterly fluctuations. These fluctuations are due to numerous factors, including:
| ‑ |
the timing, size and mix of sales of our products; |
| ‑ |
fluctuations in demand for our products, including the increase, decrease, rescheduling or cancellation of significant customer orders; |
| ‑ |
our ability to design, manufacture and deliver products which meet customer requirements in a timely and cost-effective manner; |
| ‑ |
the gain or loss of key customers; |
| ‑ |
changes in our pricing and sales policies or the pricing and sales policies of our competitors; |
| ‑ |
seasonality of certain of our products and manufacturing capabilities; |
| ‑ |
quality control or yield problems in our manufacturing operations; |
| ‑ |
supply disruption for certain raw materials and components used in our products; |
| ‑ |
capacity constraints of our outside contract manufacturers for a portion of the manufacturing process for some of our products; |
| ‑ |
length and variability of the sales cycles of our products; |
| ‑ |
unanticipated increases in costs or expenses, including rising inflation or other changes in macroeconomic conditions; |
| ‑ |
the loss of key employees; |
| ‑ |
different capital expenditure and budget cycles for our customers, affecting the timing of their spending for our products; |
| ‑ |
political stability in the areas of the world in which we operate; |
| ‑ |
changes in or limitations imposed by trade protection laws or other regulatory orders or requirements in the United States or in other countries, including tariffs, sanctions, or other costs, restrictions, or requirements which may affect our ability to import or export our products to or from various countries; and |
|
|
‑ | trade-related government actions that impose barriers or restrictions that would impact our ability to sell or ship products to customers. |
The foregoing factors are difficult to forecast, and these, as well as other factors, could materially adversely affect our quarterly and annual operating results. In addition, a significant amount of our operating expenses are relatively fixed in nature due to our internal manufacturing, research and development, sales and general administrative efforts. Any failure to adjust spending quickly enough to compensate for a revenue shortfall could magnify the adverse impact of such revenue shortfall on our results of operations. For these reasons, you should not rely on quarter-to-quarter comparisons of our results of operations as an indicator of future performance. Moreover, our operating results may not meet our announced guidance or the expectations of research analysts or investors, in which case the price of our common stock could decrease significantly. There can be no assurance that we will be able to successfully address these risks.
We depend on key personnel to develop and maintain our technology and manage our business in a rapidly changing market.
The continued services of our executive officers and other key engineering, sales, marketing, manufacturing and support personnel is essential to our success. For example, our ability to achieve new design wins depends upon the experience and expertise of our engineers. Any of our key employees, including our Chief Executive Officer, Chief Financial Officer, Senior Vice President and North America General Manager and Senior Vice President and Asia General Manager, may resign at any time.
To implement our business plan, we also intend to hire additional employees in expanding areas of our business. Our ability to continue to attract and retain highly skilled employees is a critical factor in our success. Competition for highly skilled personnel is intense. We may not be successful in attracting, assimilating or retaining qualified personnel to satisfy our current or future needs. Our ability to develop, manufacture and sell our products, and thus our financial condition and results of operations, would be adversely affected if we are unable to retain existing personnel or hire additional qualified personnel.
We depend on a limited number of suppliers and any supply interruption could have an adverse effect on our business.
We depend on a limited number of suppliers for certain raw materials and components used in our products. Some of these suppliers could disrupt our business if they stop, decrease or delay shipments or if the materials or components they ship have quality or reliability issues. Some of the raw materials and components we use in our products are available only from a sole source or have been qualified only from a single supplier. Furthermore, other than our current suppliers, there are a limited number of entities from whom we could obtain certain materials and components. We may also face shortages if we experience increased demand for materials or components beyond what our qualified suppliers can deliver. Our inability to obtain sufficient quantities of critical materials or components could adversely affect our ability to meet demand for our products, adversely affecting our financial condition and results of operations.
We typically have not entered into long-term agreements with our suppliers and, therefore, our suppliers could stop supplying materials and components to us at any time or fail to supply adequate quantities of materials or components to us on a timely basis. It is difficult, costly, time consuming and, on short notice, sometimes impossible for us to identify and qualify new suppliers. Our customers generally restrict our ability to change the components in our products. For more critical components, any changes may require repeating the entire qualification process. Our reliance on a limited number of suppliers or a single qualified vendor may result in delivery and quality problems, and reduced control over product pricing, reliability and performance.
Our products could contain defects that may cause us to incur significant costs or result in a loss of customers.
Our products are complex and undergo quality testing as well as formal qualification by our customers. Our customers’ testing procedures are limited to evaluating our products under likely and foreseeable failure scenarios and over varying amounts of time. For various reasons, such as the occurrence of performance problems that are unforeseeable in testing or that are detected only when products age or are operated under peak stress conditions, our products may fail to perform as expected long after customer acceptance. Failures could result from faulty components or design, problems in manufacturing or other unforeseen reasons. Any such failures could delay product shipments to our customers or result in a loss of customers. Our products are typically embedded in, or deployed in conjunction with, our customers’ products, which incorporate a variety of components, modules and subsystems and may be expected to interoperate with modules produced by third parties. As a result, not all defects are immediately detectable and when problems occur, it may be difficult to identify the source of the problem. We face this risk because our products are widely deployed in many demanding environments and applications worldwide. In addition, we may in certain circumstances honor warranty claims after the warranty has expired or for problems not covered by warranty to maintain customer relationships. Any significant product failure could result in litigation, damages, repair costs and lost future sales of the affected product and other products, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations problems, all of which would harm our business. Although we carry product liability insurance, this insurance may not adequately cover our costs arising from defects in our products or otherwise.
Future acquisitions may adversely affect our financial condition and results of operations.
As part of our business strategy, we may pursue acquisitions of companies that we believe could enhance or complement our current product portfolio, augment our technology roadmap or diversify our revenue base. Acquisitions involve numerous risks, any of which could harm our business, including:
| ‑ |
difficulties integrating the acquired business; |
| ‑ |
unanticipated costs, capital expenditures or liabilities or changes related to research in progress and product development; |
| ‑ |
diversion of financial and management resources from our existing business; |
| ‑ |
difficulties integrating the business relationships with suppliers and customers of the acquired business with our existing business relationships; |
| ‑ |
risks associated with entering markets in which we have little or no prior experience; and |
| ‑ |
potential loss of key employees, particularly those of the acquired organizations. |
Acquisitions may also result in the recording of goodwill and other intangible assets subject to potential impairment in the future, adversely affecting our operating results. We may not achieve the anticipated benefits of an acquisition if we fail to evaluate it properly, and we may incur costs in excess of what we anticipate. A failure to evaluate and execute an acquisition appropriately or otherwise adequately address these risks may adversely affect our financial condition and results of operations.
Future divestitures may adversely affect our financial condition and results of operations.
We frequently evaluate our portfolio of products and may consider divestitures or exits of businesses that we no longer believe to be an appropriate strategic fit. Divestitures may adversely impact our results if we are unable to offset the dilutive impacts from the loss of revenue associated with the divested products or businesses, or mitigate overhead costs allocated to those businesses. Furthermore, the divestitures could adversely affect our ongoing business operations, including by enhancing our competitors' positions or reducing customer confidence in our ongoing brand and products. The inability to effectively and efficiently manage divestitures with the results we expect or in the timeframe we anticipate could adversely affect our financial condition and results of operations.
Natural disasters or other catastrophic events could harm our operations.
Our operations in the U.S., China and Taiwan could be subject to significant risk of natural disasters, including earthquakes, hurricanes, typhoons, flooding and tornadoes, as well as other catastrophic events, such as epidemics, cyberattacks, terrorist attacks or wars. For example, our corporate headquarters and wafer fabrication facility in Sugar Land, Texas is located near the Gulf of Mexico, an area that is susceptible to hurricanes. We use a proprietary MBE laser manufacturing process that requires customized equipment, and this process is currently conducted and located solely at our wafer fabrication facility in Sugar Land, Texas, such that a natural disaster, cyberattack, terrorist attack or other catastrophic event that affects that facility would materially harm our operations. In addition, our manufacturing facility in Taipei, Taiwan, is susceptible to typhoons and earthquakes, and our manufacturing facility in Ningbo, China, has from time to time, suffered electrical outages. Any disruption in our manufacturing facilities arising from these and other natural disasters or other catastrophic events could cause significant delays in the production or shipment of our products until we are able to shift production to different facilities or arrange for third parties to manufacture our products. We may not be able to obtain alternate capacity on favorable terms or at all. Our property insurance coverage with respect to natural disaster is limited and is subject to deductible and coverage limits. Such coverage may not be adequate or continue to be available at commercially reasonable rates and terms. The occurrence of any of these circumstances may adversely affect our financial condition and results of operation.
Our ability to retain or recruit key personnel could be adversely affected by the lack of available shares under our equity incentive plan. In addition, if this lack causes us to be unable to settle outstanding awards in shares and such awards must instead be settled in cash, such cash settlement could deplete our available cash, which could have an adverse effect on our business and financial condition.
The success of our business and results of operations is dependent on our executive officers and other key personnel. Beginning in 2021, in order to improve our ability to retain and recruit such persons, as well as to better align our executive compensation program with the interests of our stockholders, we implemented a long-term incentive program under our Amended and Restated 2021 Equity Incentive Plan (the "2021 Plan") pursuant to which we grant performance-based equity awards that vest on the achievement of specified performance goals for a specified three-year period. These performance-based awards could be earned and become payable with respect to between 0% and 200% of the target number of shares based on the Company’s achievement of preset performance goals.
If the Company is not able to obtain shareholder approval for additional shares of common stock under the 2021 Plan in the future that are sufficient to permit outstanding awards to be settled in shares, the Company may have to incur additional cash expenditures to settle such awards in cash in lieu of shares. This could impair the effectiveness of our long-term incentive program and negatively affect our ability to retain or recruit key personnel, and cash settlement in lieu of shares could have an adverse effect on our future results and financial condition.
Legal and Regulatory Risks
We are subject to governmental export and import controls that could subject us to liability or impair our ability to compete in international markets.
We are subject to export and import control laws, trade regulations, and other trade requirements that limit which products we sell and where and to whom we sell our products. Specifically, the BIS regulates the export of most commercial items and "dual-use" goods that may have both commercial and military applications. Our products are primarily classified under Export Control Classification Numbers (ECCN) 5A991, 6A995, and EAR99. Export Control Classification requirements are dependent upon an item’s technical characteristics and dictate the licensing requirements and permissible destination, end-use, end-users, and activities of the end-user. Should the regulations applicable to our products change, or the restrictions applicable to countries to which we ship our products change, then the export of our products to such countries could be restricted. As a result, our ability to export or sell our products to certain countries and end-users could be restricted, which could adversely affect our business, financial condition, and results of operations.
New policy priorities may modify our import risks footprint affecting the flow of our products into the U.S.
Changes in our products, any change in export or import regulations or related legislation, shift in approach to the enforcement or scope of existing regulations, or change in the countries, persons, or technologies targeted by such regulations could result in delayed or decreased sales of our products to existing or potential customers. In such cases, our business and the results of operations could be adversely affected.
Our business could be negatively impacted as a result of shareholder activism.
In recent years, shareholder activists have become involved in numerous public companies. Shareholder activists frequently propose to involve themselves in the governance, strategic direction, and operations of the Company. We may in the future become subject to such shareholder activity and demands. Such demands may disrupt our business and divert the attention of our management and employees, and any perceived uncertainties as to our future direction resulting from such a situation could result in the loss of potential business opportunities, be exploited by our competitors, cause concern to our current or potential customers, and make it more difficult to attract and retain qualified personnel and business partners, all of which could adversely affect our business. In addition, actions of activist shareholders may cause significant fluctuations in our stock price based on temporary or speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business.
The unfavorable outcome of any pending or future litigation or administrative action and expenses incurred in connection with litigation could result in financial losses or harm to our business.
We have been, and in the future may be, subject to legal actions in the ordinary course of our operations, both domestically and internationally. There can be no assurances as to the favorable outcome of any litigation, arbitration or administrative action. In addition, it can be costly to defend such matters and these costs could negatively impact our financial results. Any litigation, arbitration, or other administrative action could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business.
Risks Related to Our Indebtedness and Future Financing
| - |
increasing our vulnerability to adverse economic and industry conditions; |
|
| - |
limiting our ability to obtain additional financing; |
|
| - |
requiring the dedication of a substantial portion of our cash flow from operations to service our indebtedness, which will reduce the amount of cash available for other purposes; |
|
| - |
limiting our flexibility to plan for, or react to, changes in our business; |
|
| - |
diluting the interests of our existing stockholders as a result of issuing shares of our common stock upon conversion of the 2030 Notes; and |
|
| - |
placing us at a possible competitive disadvantage with competitors that are less leveraged than us or have better access to capital. |
Our loan agreements contain restrictive covenants that may adversely affect our ability to conduct our business.
We have lending arrangements with several financial institutions, including credit facilities with several lending institutions in Asia, and BOK Financial in the U.S. Our loan agreements governing our long-term debt obligations in Asia and the U.S. contain certain financial and operating covenants that limit our management’s discretion with respect to certain business matters. Among other things, these covenants restrict our ability to incur additional debt, create liens or other encumbrances, change the nature of our business, sell or otherwise dispose of assets and merge or consolidate with other entities.
These restrictions may limit our flexibility in responding to business opportunities, competitive developments and adverse economic or industry conditions. Any failure by us or our subsidiaries to comply with these agreements could harm our business, financial condition and operating results. A breach of any of the covenants under our loan agreements, or a failure to pay interest or indebtedness when due under any of our credit facilities could result in a variety of adverse consequences, including the acceleration of our indebtedness.
We may not be able to obtain additional capital when desired, on favorable terms or at all.
We operate in a market that makes our prospects difficult to evaluate and, to remain competitive, we will be required to make continued investments in capital equipment, facilities and technological improvements. We expect that substantial capital will be required to expand our manufacturing capacity and fund working capital for anticipated growth. If we do not generate sufficient cash flow from operations or otherwise have the capital resources to meet our future capital needs, we may need additional financing to implement our business strategy, which includes:
| ‑ |
expansion of research and development; |
| ‑ |
expansion of manufacturing capabilities; |
|
| - | payment of any outstanding indebtedness; |
| ‑ |
hiring of additional technical, sales and other personnel; and |
| ‑ |
acquisitions of complementary businesses. |
If we raise additional funds through the issuance of our common stock or convertible securities, the ownership interests of our stockholders could be significantly diluted. These newly issued securities may have rights, preferences or privileges senior to those of existing stockholders. Additional financing may not, however, be available on terms favorable to us, or at all, if and when needed, and our ability to fund our operations, take advantage of unanticipated opportunities, develop or enhance our infrastructure or respond to competitive pressures could be significantly limited. If we cannot raise required capital when needed, we may be unable to meet the demands of existing and prospective customers, adversely affecting our sales and market opportunities and consequently our business, financial condition and results of operations.
Risks Related to Data Breaches and Network Infrastructures
Data breaches and cyberattacks could compromise our operations, our customers’ operations, or the operations of our contract manufacturers upon whom we rely, and cause significant damage to our business and reputation.
Cyberattacks have become more prevalent and much harder to detect and defend against. Companies, including companies in our industry, have been increasingly subject to a wide variety of security incidents, cyberattacks and other attempts to gain unauthorized access to their systems or to deny access and disrupt their systems and operations. These threats can come from a variety of sources, ranging in sophistication from an individual hacker to a state-sponsored attack. Cyber threats may be generic, or they may be custom-crafted against our information systems.
In the ordinary course of our business, we and our customers maintain sensitive data on our respective networks, including intellectual property, employee personal information and proprietary or confidential business information relating to our business and that of our customers and business partners. The secure maintenance of this information is critical to our business and reputation. Despite our implementation of network security measures, our network and storage applications have been subject to computer viruses, ransomware and other forms of cyber terrorism.
We may be subject to disruptions or failures in information technology systems and network infrastructures that could have a material adverse effect on our business and financial condition.
We rely on the efficient and uninterrupted operation of complex information technology systems and network infrastructures to operate our business. A disruption, infiltration or failure of our information technology systems as a result of software or hardware malfunctions, system implementations or upgrades, computer viruses, third-party security breaches, employee error, theft or misuse, malfeasance, power disruptions, natural disasters or accidents could cause a breach of data security, loss of intellectual property and critical data and the release and misappropriation of sensitive competitive information and partner, customer, and employee personal data. Any of these events could harm our competitive position, result in a loss of customer confidence, cause us to incur significant costs to remedy any damages and ultimately materially adversely affect our business and financial condition. To manage our growth and our increasingly complex business operations, we may need to upgrade systems and procedures, which requires management time and may result in significant additional expense. For example, we upgraded our enterprise resource planning system in fiscal 2025 in order to accommodate our expanding operations. We cannot be certain that we will institute, in a timely or efficient manner or at all, the improvements to our managerial, operational and financial systems and procedures necessary to support our anticipated increased levels of operations. Problems associated with, or disruptions resulting from, any improvement or expansion of our operational and financial systems could adversely affect our relationships with our suppliers, manufacturers, resellers and customers, inhibit our ability to expand or take advantage of market opportunities, cause harm to our reputation, result in errors in our financial and other reporting, and affect our ability to maintain an effective internal control environment and meet our external reporting obligations, any of which could harm our business and operating results and affect our stock price.
Risks Related to International Trade and Operations
Changes in U.S. and international trade policies, particularly regarding China, may materially and adversely impact our business and operating results.
The U.S. government has made statements and taken certain actions that have led and may lead to further changes to U.S. and international trade policies, including imposing additional tariffs on certain products manufactured abroad, with a specific focus on China. Since the beginning of 2018, increasing rhetoric coupled with legislative, administrative, or executive action, from several U.S. and foreign leaders has led to the imposition of increased tariffs on imports of certain materials and products. Five rounds of U.S. tariffs on imports from China (respectively the "U.S. Tariffs on China Imports") went into effect on July 2018, August 2018, September 2018, September 2019, and February 2020. In 2025, following an Executive order, all Chinese-origin products became subject to additional U.S. "Fentanyl" tariffs. "Reciprocal tariffs" were also implemented on Chinese and Taiwanese origin goods. The Chinese government has, in turn, issued reciprocal tariffs on U.S. goods. In February 2026, the U.S. Supreme Court held that that tariffs imposed under the IEEPA were unlawful. The U.S. government indicated that it may pursue additional or replacement tariffs under alternative legal authorities, including temporary measures under Section 122 of the Trade Act of 1974. In addition to country-specific tariffs, sectoral tariffs have come into effect targeting raw materials such as aluminum and rare earth minerals, as well as some finished and semifinished goods, such as semiconductors.
Due to rapid changes to U.S. import laws and applicable duties the Company faces a variety of import-related risk. Because of the political nature of U.S. trade policy, it is unknown whether and to what extent new tariffs (or other new laws or regulations) will be adopted, the duration of any existing punitive tariffs, or the effect of U.S. trade policy on the Company or our industry. A significant portion of our manufacturing operations are based in Ningbo, China; therefore, there could be material adverse effects on our business, financial condition, and/or cash flow if any new tariffs, legislation, regulations, or executive orders are implemented, or if existing trade agreements are renegotiated or if China or other affected countries take further retaliatory trade measures.
Furthermore, the implementation of tariffs both globally and between the U.S. and China specifically carries the risk of negatively impacting China’s overall economic condition, which could negatively affect our business. Bilateral tariffs could result in a decrease in the sales of our products to customers located in China or other customers selling to Chinese end users.
The Company's ability to export U.S.-made products is primarily subject to the jurisdiction of the Bureau of Industry and Security (BIS) of the U.S. Department of Commerce. Because the Company's focus on telecommunications products is a priority trade issue for BIS, the Company actively monitors licensing and export policy for our products.
Significant changes to existing international trade agreements could also lead to sourcing or logistics disruption resulting from import delays or the imposition of increased tariffs on our sourcing partners. For example, the Chinese government could require the use of local suppliers, compel companies that do business in China to partner with local companies, or otherwise provide additional government incentives or subsidies to government-backed local customers to buy from local suppliers. Changes in and responses to U.S. trade policy could reduce the competitiveness of our products and thus cause our sales and revenues to drop, which could materially and adversely impact our business and operations.
We face a variety of risks associated with our international sales and operations.
Trade-related government actions by the U.S., China or other countries that impose barriers or restrictions that would impact our ability to sell or ship products to customers or potential customers may have a negative impact on our financial condition and operations. We cannot predict the actions government entities may take in this context and we may be unable to quickly or effectively react to government actions that restrict our ability to sell to certain customers or those in certain jurisdictions. Government actions that affect our customers' ability to sell products or access critical elements of their supply chains may result in a decreased demand for their products, which may consequently reduce their demand for our products.
Our international revenue and operations are subject to several material risks, including:
| - | difficulties in staffing, managing and supporting operations in more than one country; |
| ‑ | difficulties in enforcing agreements and collecting receivables through foreign legal systems; |
| ‑ |
fewer legal protections for intellectual property in foreign jurisdictions; |
| ‑ |
foreign and U.S. taxation issues and international trade barriers, including the adoption or expansion of governmental trade tariffs, export controls, and fluctuating changes to end-use and end-user rules; |
| ‑ |
difficulties in obtaining any necessary governmental authorizations for the export of our products to certain foreign jurisdictions; |
| ‑ |
fluctuations in foreign economies including the impact of recessionary environments and inflation in the United States and other economies where we do business; |
| ‑ |
fluctuations in the value of foreign currencies and interest rates, including the impact of recessionary environments and inflation in the United States and other economies where we do business; |
| ‑ |
trade and travel restrictions; |
| ‑ |
domestic and international economic or political changes, hostilities and other disruptions in regions where we currently operate or may operate in the future; |
| ‑ |
difficulties and increased expenses in complying with a variety of U.S. and foreign laws, regulations, and trade standards, including modifications of the U.S. import regime, the Foreign Corrupt Practices Act and various modifications by the BIS to export policy; and |
| ‑ |
different and changing legal and regulatory requirements in the jurisdictions we currently operate or may operate in the future. |
Negative developments in any of these factors in China, Taiwan, the U.S., or other countries could result in a reduction in demand for our products, the cancellation or delay of orders already placed, difficulties in producing and delivering our products, threats to our intellectual property, difficulty in collecting receivables, and a higher cost of doing business. Although we maintain compliance programs throughout the Company, violations of U.S. and foreign laws and regulations may result in criminal or civil sanctions, including material monetary fines, penalties and other costs against us or our employees, and may have a material adverse effect on our business.
Our business operations conducted in China and Taiwan are important to our success. A substantial portion of our property, plants, and equipment is located in China and Taiwan. We expect to make further investments in Taiwan in the future. Therefore, our business, financial condition, results of operations and prospects are subject to economic, political, legal, and social events and developments in Asia. Factors affecting military, political or economic conditions between China and Taiwan could have a material adverse effect on our financial condition and results of operations, as well as the market price and the liquidity of our common shares.
Risks Related to Our Operations in China
Our business operations conducted in China are critical to our success. A total of $262.1 million, $111.8 million and $43.3 million or 57.5%, 44.8% and 19.9% of our revenue in the years ended December 31, 2025, 2024 and 2023 was attributable to our product manufactured at our plant in China, respectively. Additionally, a substantial portion of our property, plant and equipment, 42.8%, 46.9% and 43.0%, as of December 31, 2025, 2024 and 2023, was located in China, respectively. Therefore, our business, financial condition, results of operations and prospects are to a significant degree subject to economic, political, legal, and social events and developments in China.
The Chinese economy differs from the economies of most developed countries in many respects, including the level of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. The Chinese economy has been transitioning from a planned economy to a more market-oriented economy. Despite reforms, the government continues to exercise significant control over China’s economic growth by way of the allocation of resources, control over foreign currency-denominated obligations and monetary policy and provision of preferential treatment to particular industries or companies.
Our China subsidiary is subject to Chinese labor laws and regulations, and Chinese labor laws may increase our operating costs in China.
Risks Related to Intellectual Property Matters
If we fail to protect, or incur significant costs in defending, our intellectual property and other proprietary rights, our business and results of operations could be materially harmed.
Our success depends on our ability to protect our intellectual property and other proprietary rights. We rely on a combination of patent, trademark, copyright, trade secret and unfair competition laws, as well as license agreements and other contractual provisions, to establish and protect our intellectual property and other proprietary rights. We have applied for patents in the U.S. and in other foreign countries, some of which have been issued. In addition, we have registered certain trademarks in the U.S. We cannot guarantee that our pending applications will be approved by the applicable governmental authorities. Moreover, our existing and future patents and trademarks may not be sufficiently broad to protect our proprietary rights or may be held invalid or unenforceable in court. A failure to obtain patents or trademark registrations or a successful challenge to our patents and trademark registrations in the U.S. or other foreign countries may limit our ability to protect the intellectual property rights that these patent and trademark registrations intended to cover.
Policing unauthorized use of our technology is difficult and we cannot be certain that the steps we have taken will prevent the misappropriation, unauthorized use or other infringement of our intellectual property rights. Further, we may not be able to effectively protect our intellectual property rights from misappropriation or other infringement in foreign countries where we have not applied for patent protections and where effective patent, trademark, trade secret and other intellectual property laws may be unavailable, or may not protect our proprietary rights as fully as U.S. law. We may seek to secure comparable intellectual property protections in other countries. However, the level of protection afforded by patent and other laws in other countries may not be comparable to that afforded in the U.S.
We also attempt to protect our intellectual property, including our trade secrets and know-how, through the use of trade secret and other intellectual property laws, and contractual provisions. We enter into confidentiality and invention assignment agreements with our employees and independent consultants. We also use non-disclosure agreements with other third parties who may have access to our proprietary technologies and information. Such measures, however, provide only limited protection, and there can be no assurance that our confidentiality and non-disclosure agreements will not be breached, especially after our employees end their employment, and that our trade secrets will not otherwise become known by competitors or that we will have adequate remedies in the event of unauthorized use or disclosure of proprietary information. Unauthorized third parties may try to copy or reverse engineer our products or portions of our products, otherwise obtain and use our intellectual property, or may independently develop similar or equivalent trade secrets or know-how. If we fail to protect our intellectual property and other proprietary rights, or if such intellectual property and proprietary rights are infringed, misappropriated or duplicated, our business, results of operations or financial condition could be materially harmed.
We have taken legal actions to prevent third parties from infringing upon or misappropriating our intellectual property or from otherwise gaining access to our technology. Protecting and enforcing our intellectual property rights and determining their validity and scope could result in significant litigation costs and require significant time and attention from our technical and management personnel, which could significantly harm our business. We may not prevail in such proceedings, and an adverse outcome may adversely impact our competitive advantage or otherwise harm our financial condition and our business.
We may be involved in intellectual property disputes in the future, which could divert management’s attention, cause us to incur significant costs and prevent us from selling or using the challenged technology.
Participants in the markets in which we sell our products have experienced frequent litigation regarding patent and other intellectual property rights. While we have a policy in place that is designed to reduce the risk of infringement of intellectual property rights of others and we have conducted a limited review of other companies’ relevant patents, there can be no assurance that third parties will not assert infringement claims against us. We cannot be certain that our products would not be found infringing on the intellectual property rights of others. Regardless of their merit, responding to such claims can be time consuming, divert management’s attention and resources and may cause us to incur significant expenses. Intellectual property claims against us could force us to do one or more of the following:
| ‑ |
obtain from a third party claiming infringement a license to the relevant technology, which may not be available on reasonable terms, or at all; |
| ‑ |
stop manufacturing, selling, incorporating or using our products that use the challenged intellectual property; |
| ‑ |
pay substantial monetary damages; or |
| ‑ |
expend significant resources to redesign the products that use the technology and to develop non-infringing technology. |
Any of these actions could result in a substantial reduction in our revenue and could result in losses over an extended period of time.
In any potential intellectual property dispute, our customers could also become the target of litigation. Because we often indemnify our customers for intellectual property claims made against them with respect to our products, any claims against our customers could trigger indemnification claims against us. These obligations could result in substantial expenses such as legal expenses, damages for past infringement or royalties for future use. Any indemnity claim could also adversely affect our relationships with our customers and result in substantial costs to us.
Risks Related to Our Common Stock
Our stock price has been and is likely to be volatile.
The market price of our common stock has been and is likely to be subject to wide fluctuations in response to, among other things, the risk factors described in this section of this Form 10-K, and other factors beyond our control, such as fluctuations in the valuation of companies perceived by investors to be comparable to us. For example, announcements made by competitors regarding factors influencing their business may cause fluctuations in the valuation of companies throughout our industry, including fluctuations in the valuation of our stock.
Furthermore, the stock markets have experienced 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 affect the market price of our common stock.
In the past, many companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We have been and may become the target of this type of litigation in the future.
Our charter documents, stock incentive plans and Delaware law could prevent a takeover that stockholders consider favorable and could also reduce the market price of our stock.
Our Restated Certificate of Incorporation and our Amended and Restated Bylaws and our stock incentive plans contain provisions that could delay or prevent a change in control of our company. These provisions could also make it more difficult for stockholders to elect directors and take other corporate actions. These provisions include:
| ‑ | providing for a classified board of directors with staggered, three-year terms; |
| ‑ | not providing for cumulative voting in the election of directors; |
| ‑ |
authorizing our board of directors to issue, without stockholder approval, preferred stock rights senior to those of common stock; |
| ‑ |
prohibiting stockholder action by written consent; |
| ‑ |
limiting the persons who may call special meetings of stockholders; |
| ‑ |
requiring advance notification of stockholder nominations and proposals; and |
| ‑ |
change of control provisions in our stock incentive plans, and the individual stock option agreements, which provide that a change of control may accelerate the vesting of the stock options and equity awards issued under such plans. |
In addition, we are governed by the provisions of Section 203 of the Delaware General Corporate Law. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding common stock, from engaging in certain business combinations without the approval of substantially all of our stockholders for a certain period of time.
These and other provisions in our Restated Certificate of Incorporation, our amended and restated bylaws and under Delaware law could discourage potential takeover attempts, reduce the price that investors might be willing to pay for shares of our common stock in the future and result in the market price being lower than it would be without these provisions.
Our Restated Certificate of Incorporation includes a forum selection clause, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us.
Our Restated Certificate of Incorporation provides that, unless the Company consents 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 behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to the Company or the Company's stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or the Company's Restated Certificate of Incorporation or By-laws, or (iv) any action asserting a claim against the Company governed by the internal affairs doctrine. This exclusive forum provision will not apply to claims under the Securities Exchange Act of 1934 but will apply to other state and federal law claims including actions arising under the Securities Act of 1933 (although our stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder). Section 22 of the Securities Act of 1933, however, creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act of 1933 or the rules and regulations thereunder. Accordingly, there is uncertainty as to whether a court would enforce such a forum selection provision as written in connection with claims arising under the Securities Act of 1933. This forum selection provision in our Restated Certificate of Incorporation may limit our stockholders' ability to obtain a favorable judicial forum for disputes with us. It is also possible that a court could rule that such a provision is inapplicable or unenforceable.

Risk Management and Strategy
Collaboration
Our cybersecurity risks are identified and addressed through a cross-functional approach. Key security, risk, and compliance stakeholders meet to develop strategies for preserving the confidentiality, integrity and availability of Company and customer information, identifying, preventing and mitigating cybersecurity threats, and effectively responding to cybersecurity incidents. We maintain controls and procedures that are designed to ensure prompt escalation of certain cybersecurity incidents so that decisions regarding public disclosure and reporting of such incidents can be made by management and the Board in a timely manner.
Risk Assessment
At least annually, we conduct a cybersecurity risk assessment that takes into account information from internal stakeholders, known information security vulnerabilities, and information from external sources (e.g., reported security incidents that have impacted other companies, industry trends, and evaluations by parties and consultants). The results of the assessment are used to drive alignment on, and prioritization of, initiatives to enhance our security controls, make recommendations to improve processes, and inform a broader enterprise-level risk assessment that is presented to our Board and members of management.
Technical Safeguards
We regularly assess and deploy technical safeguards designed to protect our information systems from cybersecurity threats. Such safeguards are regularly evaluated and improved based on vulnerability assessments, cybersecurity threat intelligence and incident response experience.
Incident Response and Recovery Planning
We have established comprehensive incident response and recovery plans and continue to evaluate the effectiveness of those plans. Our incident response and recovery plans address — and guide our employees, management and the Board on — our response to a cybersecurity incident.
Education and Awareness
Our policies require our employees to contribute to our data security efforts. We provide awareness training to our employees to help identify, avoid and mitigate cybersecurity threats. Our employees participate annually in required training, including spear phishing and other awareness training.

For a discussion of the year ended December 31, 2024 compared to the year ended December 31, 2023, please refer to Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2024.
Overview
We are a leading, vertically integrated provider of fiber-optic networking products. We target four networking end-markets: internet data centers, CATV, telecom and FTTH. We design and manufacture a range of optical communications products at varying levels of integration, from components, subassemblies and modules to complete turn-key equipment. In designing products for our customers, we typically begin with the fundamental building blocks of lasers and laser components. From these foundational products, we design and manufacture a wide range of products to meet our customers’ needs and specifications, and such products differ from each other by their end market, intended use and level of integration. We are primarily focused on the higher-performance segments within the internet data center, CATV, telecom and FTTH markets which increasingly demand faster connectivity and innovation. Our vertically integrated manufacturing model provides us several advantages, including rapid product development, fast response times to customer requests and control over product quality and manufacturing costs.
The four end markets we target are all driven by significant bandwidth demand fueled by the growth of network-connected devices, video traffic, cloud computing and online social networking. Within the internet data center market, we benefit from the increasing use of higher-capacity optical networking technology as a replacement for older, lower-speed optical interconnects, particularly as speeds reach 800Gbps and above, as well as the movement to open internet data center architectures and the increasing use of in-house equipment design among leading internet companies. Within the CATV market, we benefit from a number of ongoing trends including the move to higher bandwidth networks among CATV service providers, especially the desire by MSOs to increase the return-path bandwidth available to offer to their customers. In the FTTH market, we benefit from continuing PON deployments and system upgrades among telecom service providers. In the telecom market, we benefit from deployment of new high-speed fiber-optic networks by telecom network operators, including 5G networks.
In 2025, 2024 and 2023, our revenue was $455.7 million, $249.4 million and $217.6 million, and our gross margin was 30.1%, 24.8% and 27.1%, respectively. We have grown our annual revenue at a compound annual growth rate, or CAGR, of 5.7% between 2016 and 2025. In the years ended December 31, 2025, 2024 and 2023, we had net loss of $38.2 million, $186.7 million and $56.0 million, respectively. At December 31, 2025 and 2024, our accumulated deficit was $491.0 million and $451.9 million, respectively. In 2025, we earned 53.8% of our total revenue from the CATV market and 42.9% of our total revenue from the internet data center market.
We sell our products to leading OEMs in the CATV, telecom, and FTTH markets as well as internet data center operators and CATV MSOs. In 2025, revenue from CATV market, the internet data center market, telecom market, FTTH and other markets provided 53.8%, 42.9%, 3.0% and 0.3% of our revenue, respectively, compared to 35.2%, 59.5%, 4.4% and 0.9%, respectively, in 2024. In 2025, our key customer in the CATV market was Digicomm. In 2025, 2024, and 2023, Digicomm accounted for 53.1%, 34.1% and 11.3% of our revenue, respectively, and in 2023, ATX Networks accounted for 15.6% of our revenue. In 2025, our key customer in the internet data center market was Microsoft. In 2025, 2024 and 2023, Microsoft accounted for 28.8%, 46.6% and 18.4% of our revenue, respectively, and in 2024, Oracle accounted for 12.4% of our revenue.
In 2025, our increase of revenue of 82.8% over the prior-year was driven primarily by increased demands both for our CATV products and internet data center products, which we believe is arising from demand for products necessary for new data center construction along with data center upgrades to enable new technologies like AI. Based on customer forecasts and order backlog we believe that this elevated data center demand will likely continue into 2026. We also believe that sales in our CATV market will increase in 2026.
We expect continued sales of our 40 Gbps, 100 Gbps, and 400 Gbps products in 2026, and we expect that sales of 800 Gbps products will likely exceed sales of 400 Gbps products later in 2026. However, quarter-to-quarter results may show considerable variability as is usual in a period of technology transition. Similar to revenue, our gross margins can fluctuate materially depending on a variety of factors including average selling price changes, product mix, global supply chain situation, raw material cost reduction or increase, manufacturing utilization rate and changes in manufacturing efficiency.
Our sales model focuses on direct engagement and close coordination with our customers to determine product design, qualifications, performance and price. Our strategy is to use our direct sales force to sell to key accounts and to expand our use of distributors for increased coverage in certain international markets and certain domestic market segments. We have direct sales personnel that cover the U.S., Taiwan and China focusing primarily on major OEM customers and internet data center operators along with CATV MSOs. Throughout our sales cycle, we work closely with our customers to qualify our products into their product lines. As a result, we strive to build strategic and long-lasting customer relationships and deliver products that are customized to our customers’ requirements.
Our business depends on winning competitive bid selection processes to develop components, systems and equipment for use in our customers’ products. These selection processes are typically lengthy, and as a result our sales cycles will vary based on the level of customization required, market served, whether the design win is with an existing or new customer and whether our solution being designed in our customers’ product is our first generation or subsequent generation product. We do not have any long-term purchase commitments (in excess of one year) with any of our customers, most of whom purchase our products on a purchase order basis, however, once one of our solutions is incorporated into a customer’s design, we believe that our solution is likely to continue to be purchased for that design throughout that product’s life cycle because of the time and expense associated with redesigning the product or substituting an alternative solution.
In 2025, 2024 and 2023, we had 9, 8 and 6 design wins, respectively. We define a design win as the successful completion of the evaluation stage, where our customer has tested our product, verified that our product meets substantially all of their requirements and has informed us that they intend to purchase the product from us. Although we believe that our ability to obtain design wins is a key strength and can provide meaningful and recurring revenue, an increase or decrease in the mere number of design wins does not necessarily correlate to a likely increase or decrease in revenue, particularly in the short term. As such, the number of design wins we achieve on a quarterly or annual basis and any increase or decrease in design wins will not necessarily result in a corresponding increase or decrease in revenue in the same or immediately succeeding quarter or year. For example, if our total number of design wins in an annual or quarterly period increases or decreases compared to the total number of design wins in a prior period, this does not necessarily mean that our revenue in such period will be higher or lower than our revenue in the prior period. In fact, our experience is that some design wins result in significant revenue and some do not, and the timing of such revenue is difficult to predict as it depends on the success of the end customer’s product that uses our components. Thus, some design wins result in orders and significant revenue shortly after the design win is awarded and other design wins do not result in significant orders and revenue for several months or longer after the initial design win (if at all). We do believe that over a period of years the collective impact of design wins correlates to our overall revenue growth.
Factors Affecting Our Performance
Increasing Demand for Data Center Connectivity, Especially for AI applications. Our large hyperscale customers are increasingly deploying massive data centers to support AI compute (e.g. training AI models, and drawing inferences from those models). As the demand for AI compute increases, so does the demand for interconnection between compute elements. Our products are used to interconnect network elements within data centers generally, and our 800G products in particular are used to interconnect AI compute infrastructure. Increasing use of AI and building more sophisticated and compute-intensive AI models directly drives the need for our products in interconnects within these AI-focused data centers.
Increasing Consumer Demand for Bandwidth. Bandwidth demand in all of our target markets is driving service provider investment in new equipment and in turn generating demand for our products. Increasingly, optical networking technologies are being incorporated into networking equipment, replacing legacy copper-based networking technologies. This shift to optical networking solutions benefits us as a provider of those solutions.
Pricing, Product Cost and Margins. Our products are sold in a highly competitive marketplace, and in many cases our products are only minimally differentiated from those of our competitors. In addition, our sales are heavily concentrated with a small number of end customers. As a result, there is strong pricing pressure across many of our product lines. We have addressed this strong pressure in several ways:
| ‑ |
Lowering our material costs. In some cases, we are able to negotiate more favorable pricing from our raw material suppliers. Also, where feasible, we are often able to develop internal production for certain materials that were previously purchased from other companies. This generally has resulted in lower material costs for us. |
| ‑ |
Enhancing the efficiency of our production process. We have been able to automate many of our production processes, which often results in lower labor costs and reduced scrap or rework rates, both of which lower our production cost. In some cases, we have been able to redesign our products to make them less complex to manufacture, and when possible during these redesigns we also incorporate lower cost raw materials. |
| ‑ |
Introducing new products. In many cases, newly released products have more features and often higher prices compared with older products. By regularly introducing new products, we attempt to minimize the average price reduction we experience. However, we often initially experience lower gross margins on new products, as our pricing is based upon anticipated volume-driven cost reductions over the life of the design win. Thus, if we are unable to realize our expected cost reductions, we may experience declining gross margins on such products. |
Our product pricing is established when the product is initially introduced to the market, and thereafter through periodic negotiations with customers. Furthermore, due to the dynamics in the CATV market and the value of our outsourced design services to our customers, we believe we face less downward price pressure than many of our competitors in this market. We sell a wide variety of products among our four target markets and our gross margin is heavily dependent in any quarter on the product mix achieved during that period as well as any price changes that we have agreed upon with our customers.
Customer Concentration within End Markets. Our revenue tends to be split primarily between CATV market and data center market. Moreover, within these markets, revenue tends to be concentrated among a small number of customers. We have taken several actions to increase the diversity of our customer base. These actions include hiring additional sales staff to improve our ability to serve new customers and introduction of new products that we believe will appeal to new customers. Furthermore, we have developed additional original design manufacturer, or ODM, relationships with customers in each of our target markets which should enable us to diversify our revenue base. We had two customers that accounted for more than 10% of our revenue in 2025 and three customers that accounted for more than 10% of our revenue in 2024. Given the size of our data center customers, however, we continue to expect high concentration of our revenue with the largest of these customers.
Product Development. We invest heavily to develop new and innovative products. The majority of our research and development expense is allocated to product development, usually with a specific customer and customer platform in mind. We believe our close coordination with our customers regarding their future product requirements enhances the efficiency of our research and development expenditures.
Discussion of Financial Performance
Revenue
We generate revenue through the sale of our products to equipment providers for the internet data center, CATV, telecom, FTTH and other markets. We derive a significant portion of our revenue from our top ten customers, and we anticipate that we will continue to do so for the foreseeable future. The following chart provides the revenue contribution from each of the markets we serve for the years 2025, 2024 and 2023, as well as the corresponding percentage of our total revenue for each period (in thousands, except percentages):

In 2025, 2024 and 2023, our top ten customers represented 96.6%, 95.0% and 92.7% of our revenue, respectively.
Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of control of products or services. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or providing services. A majority of our annual sales are denominated in U.S. dollars, but some sales from our Taiwan location and China-based subsidiary are denominated in NT dollars and RMB, respectively. For the year ended December 31, 2025, 57.5% of our total revenue was manufactured at our China-based subsidiary, with $3.4 million denominated in RMB and 38.2% of our total revenue was from products manufactured at our Taiwan-based facility, with no revenue denominated in NT dollars. We expect a similar (negligible) portion of our sales to be denominated in foreign currencies in 2026. In 2026, we expect to expand our manufacturing operations in the U.S. and Taiwan, with these two locations contributing more meaningfully to total revenue than in prior years.
Cost of goods sold and gross margin
Our cost of goods sold is impacted by variances arising from changes in yields and production volume, as well as increases or decreases in the cost of raw materials used in production. We typically experience lower yields and higher associated costs on new products, especially during the initial phase of the production. For our mature products, we can experience lower yields and higher production costs if customer requirements change or if we experience manufacturing difficulties or quality issues during our production process. Notwithstanding the foregoing, however, in general for our mature products our cost of goods sold for a particular product declines over time as a result of increasing efficiencies in the manufacturing processes, or supply cost declines, as well as yield improvements and testing enhancements.
We manufacture products in our facilities located in the U.S., Taiwan and China. Generally, laser chips and optical components are manufactured in our Sugar Land facility, and optical components, subassemblies and optical equipment are manufactured in our Taiwan and China facility. Because of our vertical integration model, we generally utilize our own optical component products in our semi-finished and finished goods that we sell between and among our respective manufacturing operations. We base those internal sales upon established transfer pricing methodologies. However, we eliminate all of those internal sales, and cost of goods sold transactions, to arrive at total revenue and cost of goods sold on a consolidated basis.
We have a global set of suppliers to help balance considerations related to product availability, quality and cost. Components of our cost of goods sold are denominated in U.S. or NT dollars or RMB, depending upon the manufacturing location.
Gross profit as a percentage of total revenue, or gross margin, has been and is expected to continue to be affected by a variety of factors, including the introduction of new products, production volumes, the mix of products sold, the geographic region in which products are sold, changes in the cost and volumes of materials purchased from our suppliers, changes in labor costs, changes in overhead costs, reserves for excess and obsolete inventories and changes in the average selling prices of our products. Although our overall gross margins over the past three years have been between 24.8% and 30.0%, our gross margins vary more broadly on a product-by-product basis. Our newer and more advanced products typically have higher average selling prices and higher gross margins; however, until the product volumes scale, the gross margin from newer and advanced products may initially be lower. Within our markets, we may sell similar products to different geographic regions at different prices, and therefore realize different gross margins among those similar products. Our strategy is to improve our gross margins through vertical integration such as utilization of our own laser chips and optical sub-components in our solutions. We expect that our gross margins are likely to continue to fluctuate from quarter to quarter because of the variety of products we sell and the relative product mix within a quarter.
Operating expenses
Our operating expenses consist of research and development, sales and marketing, and general and administrative expenses. Personnel costs are the most significant component of operating expenses and include salaries, benefits, bonuses and share-based compensation. With regard to sales and marketing expense, personnel costs also include sales commissions.
Research and development.
Research and development, or R&D, expense consists primarily of personnel costs, including share-based compensation for R&D personnel, and R&D work orders (that include material, direct labor and allocated overhead), as well as allocated development costs, such as engineering services, software and hardware tools, depreciation of capital equipment and facility costs. We record all research and development expense as incurred. Customers rely upon us to assist them with the development of new products and modification of existing products because of our extensive optical design and manufacturing expertise. We work closely with our customers in the critical design phase of product development and are occasionally reimbursed for some of these development efforts. We expect research and development expense to increase on a dollar basis, but will likely decrease as a percentage of our revenue to the extent that revenue increases over time.
Sales and marketing.
Sales and marketing expense consists primarily of personnel costs, including share-based compensation for our sales and marketing personnel, as well as travel and trade show expenses, shipping and tariff expenses, sales commissions and the allocation of overall corporate services and facility costs. We sell our products to customers who either incorporate our products into their own products, use them in their own infrastructure, or resell our products to end customers. Because we sell to a limited number of well-established customers, we employ a limited number of sales professionals who are able to cover large markets. We compensate our sales staff through base salary and commissions, with base salary being the largest component of overall compensation. Total sales commissions to employees amounted to less than one percent of our revenue in 2025, 2024 and 2023. Additionally, we pay commissions to third parties on certain product lines and identified customers, which also amounted to less than one percent of our revenue in 2025, 2024 and 2023. As such, our sales and marketing expense does not directly increase with revenue. In the future, we expect sales and marketing expense to increase on a dollar basis as we incrementally increase our overall sales activities, but expect our sales and marketing expense to decline as a percentage of revenue, to the extent our revenue increases over time.
General and administrative.
General and administrative expense consists primarily of personnel costs, including share-based compensation, primarily for our finance, human resources, legal and information technology personnel and certain executive officers, as well as professional services costs related to accounting, tax, banking, legal and information technology services, depreciation of capital equipment and facility costs. We expect general and administrative expense to increase as we continue to grow in both size and complexity as a public company. We expect rising costs including increased audit and legal fees, costs to comply with rules and regulations applicable to companies listed on a national stock exchange, as well as investor relations expense and higher insurance premiums. In the future, we expect general and administrative expense to increase on a dollar basis but to decline as a percentage of revenue, to the extent that our revenue increases over time.
Other income (expense)
Interest income consists of income earned on our cash, cash equivalents and short-term investments. Interest expense consists of amounts paid for interest on our short-term and long-term debt borrowings, and convertible senior notes.
Other income (expense), net is primarily made up of government subsidized income, extinguishment of debt and foreign currency transaction gains and losses. The functional currency of our China subsidiary is the RMB and the foreign currency transaction gains and losses of our China subsidiary primarily result from their transactions in U.S. dollars. The functional currency of our Taiwan location is the NT dollar and the foreign currency transaction gains and losses of our Taiwan location primarily result from their transactions in U.S. dollars.
Income taxes
We are a U.S. registered company and are subject to income taxes in the U.S. We also operate in a number of countries throughout the world, including Taiwan and China. Consequently, our effective tax rate is impacted by the geographic distribution of our earnings or losses and the tax laws and regulations in each geographical region. We expect that our income taxes will vary in relation to our profitability and the geographic distribution of our profits. In 2025, 2024 and 2023 our effective tax rate was 17.97%.
Our wholly owned subsidiary, Global Technology, Inc., has received preferential tax concessions in China as a national high-tech enterprise. In March 2007, China’s parliament enacted the PRC Enterprise Income Tax Law, or the EIT Law, under which, effective January 1, 2008, China adopted a uniform income tax rate of 25% for all enterprises including foreign invested enterprises. Global was recognized as a national high-tech enterprise in 2008 and was entitled to a 15% tax rate for a three-year period. Global renewed its national high-tech enterprise certificate in 2011, 2014, 2017, 2020, and 2023 extending its three-year tax preferential status through December 2026.
For the years ended December 31, 2025 and 2024, we had $0.2 million each, of unrecognized tax benefits related to U.S. tax benefits recognized for which we do not meet the more likely than not threshold.
See additional information regarding income taxes in Note O, included in Part II, Item 8 of this Form 10-K.
Seasonality
We are uncertain whether the demand for our internet data center, CATV, telecom and FTTH products is seasonal, as our sales data does not indicate a significant trend with respect to these products. Our Ningbo, China factory experiences a lengthy shut-down associated with the Lunar New Year holiday which occurs in the first quarter of each year. In addition to the factory shut-down, it is also common for employees in the factory to fail to return to work following resumption of operations. In the years 2025, 2024, and 2023, the percentage of employees in our China factory who resigned or were terminated during the first quarter, relative to the average number of employees during the quarter was 7.9%, 17.2% and 53.8% , respectively. As a result of employee turnover, we must hire and train replacement employees. These replacement employees require a period of training and improvement, and this impacts the quantity of products we can produce in the quarter. The combined effect of the factory shut-down and employee turnover in the quarter may also contribute to negative seasonality in the first quarter. In 2025, we began to produce more of our CATV and internet data center products outside of China which we believe will be instrumental in alleviating some of the typical seasonality that we see in the first quarter.
Our gross margin varies quarter to quarter and varies primarily due to the product mix in a particular quarter, as well as from the level of manufacturing efficiencies, production yields (particularly in the laser chip fabrication process) and overall supply costs.

Comparison of Years Ended December 31, 2025 and 2024
Revenue
We generate revenue through the sale of our products to equipment providers and network operators for the internet data center, CATV, telecom, FTTH and other markets. We derive a significant portion of our revenue from our top ten customers, and we anticipate that we will continue to do so for the foreseeable future. The following charts provide the revenue contribution from each of the markets we served for the years ended December 31, 2025 and 2024 (in thousands, except percentages):

Revenue increased by $206.4 million, or 82.8%, from 2024 to 2025. The increase was driven primarily by increased demand in the CATV market, which we believe is due to large scale deployments of our DOCSIS 4.0 products in 2025, and increased demand for our internet data center products, arising from demand for products necessary for new data center construction along with data center upgrades to enable new technologies like AI. Based on customer forecasts and order backlog we believe that this elevated data center demand will likely continue into 2026. We also believe that sales in our CATV market will increase in 2026 as a result of further adoption of our DOCSIS 4.0 products, including adoption by new customers.
In the years ended December 31, 2025 and 2024, our top ten customers represented 96.6% and 95.0% of our revenue, respectively. We believe that diversifying our customer base is critical for our future success, since reliance on a small number of key customers makes our ability to forecast future results dependent upon the accuracy of the forecasts we receive from those key customers.

Cost of goods sold increased by $131.2 million, or 70.0%, from 2024 to 2025. The increase in 2025 was primarily attributable to higher direct material and direct labor costs associated with increased revenue volumes, as well as an increase in inventory reserves.The increase in the reserve is consistent with the higher inventory levels and overall business expansion in 2025.
The increase in gross margin for the year ended December 31, 2025 compared to the same period ended December 31, 2024 was primarily driven by larger scale production of our CATV products, which resulted in improved manufacturing efficiencies and lower cost variances.

Research and development expense
Research and development expense increased $30.6 million, or 55.6%, from 2024 to 2025. Research and development costs consist of R&D work orders, R&D material usage and other project related costs related to 100 Gbps, 200/400/800/1,600 Gbps data center products, DOCSIS 4.0 capable CATV products, including 1.8 GHz-capable amplifier products, and other new product development, and depreciation expense resulting from R&D equipment investments. The expenses increased due to a higher volume of internal work orders and headcount increase. During 2025, we experienced increased interest in new technologies like 800G and 1.6T among our data center customers. Supporting customer testing and qualification for these new opportunities materially increased our R&D expenditures, and to the extent that we continue to see elevated customer interest in these new technologies we also expect continued elevated R&D expenditures relative to historical averages. We continue to place a high degree of strategic focus on innovation and product development to support future growth.
Sales and marketing expense
Sales and marketing expense increased by $12.1 million, or 66.7%, from 2024 to 2025. These increases were primarily due to more sales effort for our Quantum Bandwidth™ products and higher shipping expenses, including tariffs.
General and administrative expense
General and administrative expense increased by $16.1 million, or 27.1%, from 2024 to 2025. These increases were primarily due to the higher professional service fees and increased headcount and offset by decreased share-based compensation.

Interest income increased by $0.9 million, or 105.0%, from 2024 to 2025. The increase was primarily due to higher savings balance in 2025.
Interest expense decreased by $3.3 million, or 48.8%, from 2024 to 2025. The decrease was primarily due to a lower effective interest rate on the 2030 Notes in 2025 and the absence of loss on extinguishment, which was recognized in 2024 in connection with the exchange of the 2030 Notes with the 2026 Notes.
Other expense of $109.9 million in 2024 shifted to other income of $9.6 million in 2025. This favorable variance was primarily due to the absence of debt extinguishment costs related to the 2026 Notes, which in the prior period reflected the difference between the carrying value of the 2026 Notes and their fair value at the time of settlement. The settlement resulted in a one-time loss recognized in the prior period, which increased non-operating expenses. In 2025, the company recorded $1.9 million foreign currency exchange gains and $4.9 million of government subsidies in other income.

Our income tax benefit (expense) consists of U.S. income tax, state taxes, and Taiwan and China income tax recorded during the periods. Our effective tax rate is affected by recurring items, such as tax rates in state and foreign jurisdictions, the relative amounts of income we earn in those jurisdictions, and valuation allowances on our deferred taxes.
The income tax benefit in the year ended December 31, 2025 was due primarily to the release of the valuation allowance on our wholly owned subsidiary, Global Technology, Inc. The income tax expense for the year ended December 31, 2024 was primarily related to the state tax provision and the recording of a valuation allowance on our deferred tax assets.
We recorded no federal tax expense for the years ended December 31, 2025 and December 31, 2024. The income tax expense in the years ended December 31, 2025 and December 31, 2024 was primarily related to the state tax provision and the recording of a valuation allowance on our deferred tax assets.
Liquidity and Capital Resources
As of December 31, 2025, we had $60.7 million of unused borrowing capacity from all of our loan agreements. As of December 31, 2025, our cash, cash equivalents, restricted cash and short-term investments totaled $216.0 million. Cash and cash equivalents are held for working capital purposes and are invested primarily in money market or time deposit funds.
ATM Offerings
On December 18, 2024, the Company filed an automatic shelf registration statement on Form S-3ASR (Registration File No. 333-283905) with the Securities and Exchange Commission, which became effective immediately upon filing.

Registered Direct Offering
On December 23, 2024, the Company issued an aggregate of 1,036,458 shares of the Company’s common stock, par value $0.001 per share, at a purchase price of $33.97 per share, in a registered direct offering (the "Registered Direct Offering"). The Registered Direct Offering was made pursuant to the Automatic Shelf Registration Statement. The Registered Direct Offering closed on December 23, 2024.
Raymond James and Associates, Inc. acted as the sole placement agent (the "Placement Agent") for the Company in connection with the Registered Direct Offering. Pursuant to that certain Placement Agency Agreement, dated as of December 18, 2024, between the Company and the Placement Agent, the Placement Agent is entitled to a fee equal to an aggregate of 3% of the aggregate principal amount of the Registered Direct Offering.
The Registered Direct Offering generated proceeds of approximately $33.7 million, after deducting placement agent fees and other estimated offering expenses payable by us. The Company intends to use the net proceeds from the Registered Direct Offering for general corporate purposes, which may include among other things, capital expenditures and working capital. The Company may also use such proceeds to fund acquisitions of businesses, technologies or product lines that complement its current business; however, the Company has no present plans, agreements or commitments with respect to any potential acquisition.
Note Offerings
On December 5, 2023, the Company issued approximately $80.2 million aggregate principal amount of 5.250% convertible senior notes due 2026 (the "2026 Notes"), bearing interest at a rate of 5.250% per year maturing on December 5, 2026, unless earlier repurchased, redeemed or converted in accordance with their terms. The sale of the 2026 Notes generated net proceeds of $76.2 million, after expenses. On July 30, 2025, the Company retired the final $3.5 million principal and accrued and unpaid interest on the 2026 Notes by exchanging such outstanding principal for 239,404 shares of the Company's common stock and by paying the accrued and outstanding interest in cash.

See Note K "Notes Payable and Long-term Debt" and Note L "Convertible Senior Notes" of our Consolidated Financial Statements for a description of our notes payable and long-term debt and convertible senior notes.
Future liquidity needs
We believe that our existing cash and cash equivalents, cash flows from our operating activities, and available credit will be sufficient to meet our anticipated cash needs for the next 12 months. Our future capital requirements will depend on many factors including our growth rate, the timing and extent of spending to support our research and development efforts, the expansion of our sales and marketing activities, the introduction of new and enhanced products, changes in our manufacturing capacity and the continuing market acceptance of our products. In the event we need additional liquidity, we will explore additional sources of liquidity. These additional sources of liquidity could include one, or a combination, of the following: (i) issuing equity or debt securities, (ii) incurring indebtedness secured by our assets and (iii) selling product lines, other assets and/or portions of our business. There can be no guarantee that we will be able to raise additional funds on terms acceptable to us, or at all.
Contractual Obligations and Commitments
We have outstanding notes payable and debt with varying maturities with various financial institutions. As of December 31, 2025, our debt had an amount of $34.0 million, which is due within 12 months. Further information regarding our notes payable is provided in Note K – Notes Payable and Long-Term Debt in the Notes to Consolidated Financial Statements in this Form 10-K. We also have fixed-rate convertible senior notes. As of December 31, 2025, the 2030 Notes had an aggregate principal amount of $125 million and future interest payments associated with the 2030 Notes totaled $10.5 million. Further information regarding our convertible senior notes is provided in Note L – Convertible Senior Notes in the Notes to Consolidated Financial Statements in this Form 10-K. In addition, we have operating leases for certain property and equipment with an expected term at the commencement date of more than 12 months. As of December 31, 2025, the future minimum payments required under these leases totaled $63.2 million, with $5.2 million payable within 12 months. Further information regarding our leases is provided in Note D – Leases to Consolidated Financial Statements in this Form 10-K.
Inflation
The annual inflation rate in the US came down to 2.7% in 2025, compared with 2.9% in 2024. Even though the inflation has slowed from the peak, it remained above the Federal Reserve's objective of 2%. The annual inflation rate in Taiwan came down to around 1.7% in 2025 from 2.1% in 2024. The cost of inflation was reflected in increases in shipping costs, labor rates, and in costs of some raw materials. We believe these decreases are related to the supply chain pressure easing and decreasing commodity prices, however the labor market is still tight, and the wage pressure is still high. We cannot be sure when or if prices will return to pre-pandemic levels. Compared to other major economies in the world, China has a stable level of inflation, which has not had a significant impact on our sales or operating results. However, there is no guarantee that we may increase selling prices or reduce costs to fully mitigate the effect of inflation on our costs, which may adversely impact our sales margins and profitability.
Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. These principles require us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses and cash flows, and related disclosure of contingent assets and liabilities. Our estimates include those related to revenue recognition, share-based compensation expense, impairment analysis of goodwill and long-lived assets, valuation of inventory, warranty liabilities and accounting for income taxes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates. To the extent that there are material differences between these estimates and our actual results, our future financial statements will be affected.
We believe that of our significant accounting policies, which are described in Note B to our consolidated financial statements appearing elsewhere in this Form 10-K, the following accounting policies involve a greater degree of judgment and complexity. Accordingly, we believe these are the most critical to fully understand and evaluate our financial condition and results of operations.
Long-lived assets
We evaluate the carrying value of long-lived assets for potential impairment when we determine a triggering event has occurred, or whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. When indicators exist, recoverability of assets is measured by a comparison of the carrying value of the asset group to the estimated undiscounted future net cash flows expected to be generated by the asset group. Examples of such triggering events include a significant disposal of a portion of such assets, an adverse change in the market involving the business employing the related asset, a significant decrease in the benefits realized from an acquired business, difficulties or delays in integrating the business, and a significant change in the operations of an acquired business. If such assets are determined not to be recoverable we perform an analysis of the fair value of the asset group and will recognize an impairment loss when the fair value is less than the carrying amount of such assets. The fair value, based on reasonable and supportable assumptions and projections, require subjective judgments including meaningful asset grouping, expectations for future revenue, and disposal value for the asset(s). Depending on the assumptions and estimates used, the fair value projected in the evaluation of long-lived assets can vary within a range of outcomes. We consider the likelihood of possible outcomes in determining the best estimate for the fair value of the assets. We did not record any asset impairment charges in 2025, 2024 and 2023.
Valuation of inventories
Inventories are stated at the lower of cost (average-cost method) or net realizable value. Work in process and finished goods includes materials, labor and allocated overhead. We assess the valuation of our inventory on a periodic basis and provide an allowance for the value of estimated excess and obsolete inventory based on estimates of future demand. Inventory reserves are recorded to account for the excess and obsolete inventory combined with the lower of cost or net realizable value assessments. To develop the reserve, we developed certain percentages that determine the extent of inventory reserve adjustments based on the age of the inventory. Such percentages were determined through analysis of the inventory to determine each product's lifespan, a review of historical write-offs or scrapped inventory, and an assessment by product engineers of the possibility of obsolescence for each product.
During the years ended December 31, 2025, 2024 and 2023, we recorded excess and obsolete inventory reserve charges of $9.7 million, $3.4 million and $8.7 million, respectively. For the years ended December 31, 2025, 2024 and 2023, the direct inventory write-offs related to scrap, discontinued products and damaged inventories were $9.4 million, $3.8 million and $10.6 million, respectively.
We have an accounting policy to record a reserve for inventory encompassing the value of excess or obsolete items combined with the lower of cost or net reliable value. We considered the following factors in our determination of the appropriate reserve level: how often we buy material in bulk; the overall market value of raw material, semi-finished goods and finished goods across our varied product lines and within markets; changes in expected demand for our products; the change in valuations historically; the determined safety stock for key customers; and the likelihood of postponement in delivery schedules for materials already placed in finished goods inventory. We consider these factors to be subjective because there can be no certainty that past trends will continue and our future expectations cannot be known with certainty. If past trends in demand, for example, change, then this could materially change the values used in our estimates.
Accounting for income taxes
We account for income taxes in accordance with the provisions of ASC 740, Income Taxes. The liability method is used to account for deferred income taxes. Under the liability method, deferred tax assets and liabilities are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The ability to realize deferred tax assets is evaluated annually and a valuation allowance is provided if it is unlikely that the deferred tax assets will not give rise to future benefits in our tax returns.
On the basis of this evaluation, as of December 31, 2025, the company recognized $7.6 million deferred tax assets that are more likely than not to be realized. The amount of the deferred tax assets considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased or if objective negative evidence in the form of cumulative losses is no longer present and additional weight is given to subjective evidence such as our projections for growth.
We record uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority.
We recognize interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying consolidated statement of operations. Accrued interest and penalties are included on the related tax liability line in the consolidated balance sheet.
See additional information regarding income taxes in Note O of our Consolidated Financial Statements.

| Item 7A. |
Quantitative and Qualitative Disclosures about Market Risk |
Market Risks
Market risk represents the risk of loss that may impact our financial statements through adverse changes in financial market prices and rates and inflation. Our market risk exposure results primarily from fluctuations in foreign exchange and interest rates. We manage our exposure to these market risks through our regular operating and financing activities. We have not historically attempted to reduce our market risks through hedging instruments; we may, however, do so in the future.
Interest Rate Fluctuation Risk
Our cash equivalents consisted primarily of money market funds, and interest and non-interest bearing bank deposits. Our primary objective is to maintain the security of our principal balances and ensure liquidity. We attempt to maximize the return on these balances without significantly increasing risk, but have little opportunity to do so given the short-term nature of our investments and current interest rate environments. We do not anticipate any material effect on our cash balances or investment portfolio due to fluctuations in interest rates.
We could be exposed to interest rate risk, should we incur debt that had a floating interest rate. As of December 31, 2025, all debts bore a fixed interest rate and therefore did not generate interest rate risk. As of December 31, 2025, we had not hedged our interest rate risk.
Foreign Exchange Rates
We operate on an international basis with a large portion of our business conducted in our Taiwan branch and China subsidiary. We use the U.S. dollar as our reporting currency for our consolidated financial statements. The financial records of our China subsidiary and our Taiwan branch are maintained in their respective local currencies, the RMB and the NT dollar, which are the functional currencies for our China subsidiary and our Taiwan branch, respectively. Assets and liabilities are translated at prevailing exchange rates at the balance sheet date, equity accounts are translated at historical exchange rates and revenues, expenses, gains and losses are translated using the average rate for the then current period using a monthly average. Translation adjustments are reported as cumulative translation adjustments and are shown as a separate component of accumulated other comprehensive income in our statement of stockholders’ equity and comprehensive income.
All transactions in currencies other than their functional currencies during the year are subject to foreign exchange risk when the exchange rate fluctuates on the respective relevant dates of such transactions. Transaction gains and losses are recognized in our statements of operations in other income (expense). Monetary assets and liabilities existing at the balance sheet date denominated in currencies other than the functional currencies are re-measured at the exchange rates prevailing on the balance sheet date and unrealized exchange differences are recorded in our consolidated income statement. In October 2015, we determined that certain intercompany loans are long-term investments. Therefore, exchange gain (loss) arising from re-measurement of intercompany loans were recorded in the Cumulative Translation Adjustment accounts.
During the year ended December 31, 2025, we recognized approximately$0.1 million of exchange gain arising from foreign currency transactions and re-measurement of monetary assets and liabilities dominated in non-functional currency on the balance sheet date.
During the year ended December 31, 2025, 0.7% of our revenue was denominated in RMB and none of our revenue was denominated in NT dollars. In the year ended December 31, 2025, 21.7% of our operating expenses were denominated in RMB and 17.8% of our operating expenses were denominated in NT dollars. Accordingly, fluctuations in exchange rates directly affect our cost of goods sold and net income (loss), and have a significant impact on our operating margins. If exchange rates of RMB and NT dollars for U.S. dollars were 1% higher during the year ended December 31, 2025, our operating expenses would have had been higher by $0.8 million.
As of December 31, 2025, we held the U.S. dollar denominated liabilities net of assets of approximately $2.3 million in our China subsidiary and liabilities net of assets of $39.5 million in our Taiwan branch. With respect to these U.S. dollar denominated net assets as of December 31, 2025, if exchange rates of RMB and NT dollars for U.S. dollars were 1% higher during the year ended December 31, 2025, our other operating expenses would have been reduced by $0.4 million. Any significant revaluation of the RMB and NT dollars may materially and adversely affect the cash flows, revenues, and net income (loss) as reported in U.S. dollars.
We currently do not use derivative financial instruments to mitigate this exposure. We continue to review this issue and may consider hedging certain foreign exchange risks through the use of currency forwards or options in future years.

Controls and Procedures |
| a. |
Evaluation of Disclosure Controls and Procedures. |
The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their control objectives.
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2025. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered in this Form 10-K, our disclosure controls and procedures were effective.

Management’s Annual Report on Internal Control over Financial Reporting. |
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act). Internal control over financial reporting is a process designed by, or under the supervision of, the issuer’s principal executive and principal financial officers, or persons performing similar functions, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. 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 the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the 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 our degree of compliance with the policies or procedures may deteriorate.
Our management conducted an evaluation of the effectiveness of our internal control over financial reporting as of the end of the period covered by this Form 10-K based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organization ("COSO") of the Treadway Commission. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2025. Accordingly, management believes that the consolidated financial statements included in this Form 10-K present fairly in all material respects our financial position, results of operations, and cash flows for the period presented.
Remediation of Material Weakness Identified in 2024
As described on our Form 10-K for the year ending December 31, 2024, management identified a material weakness related to the operation of controls over our review of technical accounting analysis. Although this material weakness did not result in any material misstatement of our financial statements, we nevertheless concluded that our internal control over financial reporting was not effective as of December 31, 2024. During 2025, we took steps to remediate this material weakness, including instituting additional levels of review for technical accounting analyses, additional scrutiny of externally-prepared technical accounting analyses, and personnel changes within the Accounting department that possess knowledge of technical accounting matters sufficient to allow them to perform a review of the analysis that is precise enough to detect errors in the analysis that could lead to a conclusion that would have a material impact to the Company’s financial statements.
Under the oversight of our Audit Committee, we believe that these steps have been effective in remediating the material weakness.
Grant Thornton LLP, the independent registered public accounting firm that audited the consolidated financial statements included in this Form 10-K, has issued a report, included below, on the effectiveness of our internal control over financial reporting as of December 31, 2025.
| c. |
Changes in Internal Control over Financial Reporting |
Other than the remediation steps discussed above, there was no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) identified in connection with management’s evaluation required by the Rules 13a-15(d) and 15d-15(d) under the Exchange Act that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Definition and limitations of internal control over financial reporting
A company’s internal control over financial reporting is a process designed 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. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Board of Directors and Stockholders
Applied Optoelectronics, Inc.
Opinion on the financial statements
We have audited the accompanying consolidated balance sheets of Applied Optoelectronics, Inc. (a Delaware corporation) and subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"), and our report dated February 26, 2026, expressed an unqualified opinion.
Basis for opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical audit matters
Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.
/s/
We have served as the Company’s auditor since 2008.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
NOTE A—ORGANIZATION AND OPERATIONS
Applied Optoelectronics, Inc. ("AOI" or the "Company") was incorporated in the State of Texas on February 28, 1997. In March 2013, the Company converted into a Delaware corporation. The Company is a leading, vertically integrated provider of fiber-optic networking products, primarily for four networking end-markets: internet data center, CATV, telecom and FTTH. The Company designs and manufactures a wide range of optical communications products at varying levels of integration, from components, subassemblies and modules to complete turn-key equipment.
The Company has manufacturing and research and development facilities located in the U.S., Taiwan and China. At its corporate headquarters and manufacturing facilities in Sugar Land, Texas, the Company primarily manufactures lasers and laser components and performs research and development activities for laser component and optical module products. The Company operates in Taipei, Taiwan and Ningbo, China through its wholly-owned subsidiary Prime World International Holdings, Ltd. ("Prime World", incorporated in the British Virgin Islands). Prime World is the parent of Global Technology, Inc. ("Global", incorporated in the People’s Republic of China). Through Global, the Company primarily manufactures certain of its data center transceiver products, including subassemblies and transceivers, as well as Cable TV Broadband ("CATV") systems and equipment, and performs research and development activities for the CATV products. Prime World also operates a branch in Taiwan, which primarily manufactures transceivers. The Company also has a research and development center in Duluth, Georgia.
NOTE B—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
| 1. | Basis of Presentation |
The consolidated financial statements include the accounts of the Company and all of its wholly-owned subsidiaries and are prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). All intercompany balances and transactions have been eliminated in consolidation.
| 2. | Use of Estimates |
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates in the consolidated financial statements and accompanying notes. Significant estimates and assumptions that impact these financial statements relate to, among other things, allowance for doubtful accounts, inventory reserve, product warranty costs, share-based compensation expense, estimated useful lives of property and equipment, and taxes.
| 3. | Foreign Currency Translation |
The functional currency for the Company’s foreign operations is the local currency. The assets and liabilities of these operations are translated at the rate of exchange in effect on the balance sheet date and sales and expenses are translated at monthly average rates. The resulting gains or losses from translation are included in a separate component of other comprehensive income. There is no tax effect on the foreign currency translation because it is management’s intent to reinvest the undistributed earnings of its foreign subsidiaries indefinitely. Transaction gains and losses resulting from re-measuring monetary asset and liability accounts that are denominated in a currency other than a subsidiary’s functional currency are included in net foreign exchange gain and loss and are included in net income except for those intercompany balances that are long-term investments in nature. The translation gain or losses from the long-term investment nature of intercompany balances are treated as translation adjustments and included in comprehensive income.
| 4. | Fair Value |
The carrying value of cash, cash equivalents and short-term investments, accounts receivable, accounts payable, and note receivable approximate their historical fair values due to their short-term maturities. The carrying value of the debt and bank acceptance notes approximates its fair value due to the short-term nature of the debt since it renews frequently at current interest rates. Management believes that the interest rates in effect at each year end represent the current market rates for similar borrowings.
The fair value measurement standard defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standard characterizes inputs used in determining fair value according to a hierarchy that prioritized inputs based on the degree to which they are observable. The three levels of the fair value hierarchy are as follows:
Level 1—Inputs represent quoted prices in active markets for identical assets or liabilities.
Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
Level 3—Inputs that are not observable from objective sources, such as management’s internally developed assumptions used in pricing an asset or liability.
Assets and liabilities that are required to be fair valued on a recurring basis include money market funds, marketable securities, equity instruments and contingent consideration.
Money market funds are valued with Level 1 inputs, using quoted market prices, and are included in cash and cash equivalents on the Company’s consolidated balance sheets.
| 5. | Cash and Cash Equivalents |
The Company considers all highly liquid securities with an original maturity of ninety days or less from the date of purchase to be cash equivalents. Cash in foreign accounts was approximately $
The Company maintains cash and cash equivalents at U.S. financial institutions for which the combined account balances in individual institutions may exceed Federal Deposit Insurance Corporation ("FDIC") insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. As of December 31, 2025, approximately $
| 6. | Restricted Cash |
Restricted cash includes guarantee deposits for customs duties and deposits as collateral in order to secure bank acceptance notes issued to vendors.
| 7. | Accounts Receivable/Allowance for Doubtful Accounts |
The Company carries its accounts receivable at the net amount that it estimates to be collectible. We have established an allowance for credit losses to estimate the risk of loss associated with our accounts receivable balances. The Company estimates its allowance for the credit losses based on historical collection, the age of outstanding receivables of the customer, existing economic conditions and reasonable forecasts. Different assumptions or changes in economic circumstances could result in changes to the allowance.
| 8. | Concentration of Credit Risk and Significant Customers |
Financial instruments which potentially subject the Company to concentrations of credit risk include cash, cash equivalents and accounts receivable. The Company places all cash and cash equivalents with high-credit quality financial institutions.
The Company performs ongoing credit valuations of its customers’ financial condition whenever deemed necessary and generally does not require deposits or collateral to support customer receivables. The historical amount of losses on uncollectible accounts has been within the Company’s estimates. The Company generates much of its revenue from a limited number of customers. In 2025, 2024 and 2023, its top
The
| 9. | Inventories |
Inventories are stated at the lower of cost (average-cost method) or net realizable value. Work in process and finished goods includes materials, labor and allocated overhead. The Company assesses the valuation of its inventory on a periodic basis and provides write-offs for the value of estimated excess and obsolete inventory based on estimates of future demand. Inventory reserves are recorded to account for the excess and obsolete inventory combined with the lower of cost or net realizable value assessments. To develop the reserve, the Company developed certain percentages that determine the extent of inventory reserve adjustments based on the age of the inventory. Such percentages were determined through analysis of the inventory to determine each product's lifespan, a review historical write-offs or scrapped inventory, and an assessment by product engineers of the possibility of obsolescence for each product.
| 10. | Property, Plant and Equipment |
Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. The Company calculates depreciation using the straight-line method over the following estimated useful lives:
| Useful lives (in years) | ||||
| Buildings | | |||
| Land improvements | | |||
| Machinery and equipment | | |||
| Furniture and fixtures | | |||
| Computer equipment and software | | |||
| Leasehold improvements | The shorter of the life of the applicable lease or the useful life of the improvement | |||
| Transportation equipment | | |||
Major improvements are capitalized and expenditures for maintenance and repairs are expensed as incurred. Construction in progress represents property, plant and equipment under construction or being installed. Costs include original cost, installation, construction and other direct costs which include interest on borrowings used to finance the asset. Construction in progress is transferred to the appropriate fixed asset account and depreciation commences when the asset has been substantially completed and placed in service.
Land use rights allow the Company rights for
| 11. | Intangible Assets |
Intangible assets consist of intellectual property that is stated at cost less accumulated amortization. As of December 31, 2025, the Company had
| 12. | Impairment of Long-Lived Assets |
The Company accounts for impairment of long-lived assets in accordance with Accounting Standards Codification ("ASC") 360, Property, Plant and Equipment, ("ASC 360"). Long-lived assets consist primarily of property, plant and equipment, right-of-use assets and intangible assets. In accordance with ASC 360, the Company evaluates the carrying value of long-lived assets when it determines a triggering event has occurred, or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When indicators exist, recoverability of assets is measured by a comparison of the carrying value of the asset group to the estimated undiscounted future net cash flows expected to be generated by the asset group. Examples of such triggering events include a significant disposal of a portion of such assets, an adverse change in the market involving the business employing the related asset, a significant decrease in the benefits realized from an acquired business, difficulties or delays in integrating the business, and a significant change in the operations of an acquired business. If such assets are determined not to be recoverable, the Company performs an analysis of the fair value of the asset group and will recognize an impairment loss when the fair value is less than the carrying amounts of such assets. The fair value, based on reasonable and supportable assumptions and projections, require subjective judgments. Depending on the assumptions and estimates used, the appraised fair value projected in the evaluation of long-lived assets can vary within a range of outcomes. The Company considers the likelihood of possible outcomes in determining the best estimate for the fair value of the assets. The Company did record any asset impairment charges in 2025, 2024 or 2023.
| 13. | Comprehensive Income (Loss) |
ASC 220, Comprehensive Income, ("ASC 220") establishes rules for reporting and display of comprehensive income (loss) and its components. ASC 220 requires that unrealized gains and losses on the Company’s foreign currency translation adjustments be included in comprehensive income (loss).
| 14. | Share-based Compensation |
The Company accounts for share-based compensation in accordance with the provisions of ASC 718, Compensation—Stock Compensation. Share-based compensation expense is recognized based on the grant date fair value in order to recognize compensation cost for those shares expected to vest. Compensation cost is recognized on a straight-line basis over the vesting period of the restricted stock units and adjusted as forfeitures occur.
| 15. | Revenue Recognition |
The Company derives revenue from the manufacture and sale of fiber optic networking products. Revenue recognition follows the criteria of ASC 606, Revenue from Contracts with Customers. Specifically, the Company recognizes revenue when obligations under the terms of a contract with its customer are satisfied; generally this occurs with the transfer of control of products or services at point of time or over times. When the Company receives payments and its obligations to customers are not satisfied, the Company will recognize the payment as Unearned Revenue from customers.
| 16. | Product Warranty |
The Company generally offers a -year limited warranty for its products but it can extend for longer periods of to years for certain products sold to certain customers. The Company estimates the costs that may be incurred under its basic limited warranty and records a liability for the amount of such costs at the time when product defects occur. Factors that affect the Company’s warranty liability include the historical and anticipated rates of warranty claims and cost to repair. While the Company believes that its warranty accrual is adequate, the actual warranty costs may exceed the accrual, in which case the cost of sales will increase in the future. As of December 31, 2025 and 2024, the amount of accrued warranty was $

| 17. | Advertising Costs |
Advertising costs are charged to operations as incurred and amounted to approximately $
| 18. | Research and Development |
Research and development costs are charged to operations as incurred. The Company receives reimbursement for certain development costs, which offset with expense up to the reimbursable amount.
| 19. | Shipping and Handling Costs |
Shipping and handling costs are included in operating expenses as fulfillment costs unless we bill our customers for shipping and handling charges, which are included in net sales for the applicable period, and the corresponding shipping and handling expense is reported in cost of sales.
| 20. | Income Taxes |
The Company accounts for income taxes in accordance with the provisions of ASC 740, Income Taxes. The liability method is used to account for deferred income taxes. Under the liability method, deferred tax assets and liabilities are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The ability to realize deferred tax assets is evaluated annually and a valuation allowance is provided if it is unlikely that the deferred tax assets will not give rise to future benefits in the Company’s tax returns.
The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) it determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, it recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority.
The Company recognizes interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying consolidated statement of operations. Accrued interest and penalties are included on the related tax liability line in the consolidated balance sheet.
| 21. | Government Grant |
The Company receives incentives from local governments in China that encourage us to establish, maintain, or increase investment, employment, or production in the region. Because there is no direct applicable U.S. GAAP guidance that addresses the recognition and measurement of government assistance received by a business entity, U.S. GAAP allows for the adoption of other analogous accounting guidance under ASC 958-605 (Not-for-Profit Entities – Revenue Recognition). The Company accounts for the grant as other income based on the substance of the incentive received when the conditions associated with the grant are substantially met and collection is reasonably assured.
| 22. | Global Intangible Low-taxed Income Provisions ("GILTI") |
One of the base broadening provisions of the U.S. Tax Cuts and Jobs Act of 2017 ("the 2017 Act") is the global intangible low-taxed income provisions ("GILTI"). In accordance with guidance issued by the FASB staff, the Company has adopted an accounting policy to treat any GILTI inclusions as a period cost if and when incurred. Thus, for the fiscal years ended December 31, 2025, December 31, 2024, and December 31, 2023, deferred taxes were computed without consideration of the possible future impact of the GILTI provisions, and any current year impact was recorded as a part of the current portion of income tax expense.
| 23. | Recent Accounting Pronouncements |
Recent Accounting Pronouncements Adopted in 2025
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires the Company to disclose disaggregated jurisdictional and categorical information for the tax rate reconciliation, income taxes paid and other income tax related amounts.

There have been no other recent accounting pronouncements or changes in accounting pronouncements during fiscal 2025 that are of significance or potential significance to us.
NOTE C—REVENUE RECOGNITION
Revenue from Contracts with Customers
The Company derives revenue from the manufacture and sale of fiber optic networking products. Revenue is recognized when obligations under the terms of a contract with its customer are satisfied; generally this occurs with the transfer of control of products or services. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or providing services. Certain customers may receive cash and/or non-cash incentives, which are accounted for as variable consideration. To achieve this core principle, the Company applies the following five steps:
1. Identify the contract with a customer
A contract with a customer exists when (i) the Company enters into an agreement with a customer that defines each party's rights regarding the products or services to be transferred and identifies the payment terms related to these products or services, (ii) both parties to the contract are committed to perform their respective obligations, (iii) the contract has commercial substance, and (iv) the Company determines that collection of substantially all consideration for products or services that are transferred is probable based on the customer's intent and ability to pay the promised consideration. The Company applies judgment in determining the customer's ability and intention to pay, which is based on a variety of factors including the customer's payment history or, in the case of a new customer, published credit and financial information pertaining to the customer.
2. Identify the performance obligations in the contract
Performance obligations promised in a contract are identified based on the products or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the product or service either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the products or services is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised products or services, the Company must apply judgment to determine whether promised products or services are capable of being distinct and distinct in the context of the contract. If these criteria are not met, the promised products or services are accounted for as a combined performance obligation. The Company has elected to account for shipping and handling activities as a fulfillment cost as permitted by the standard.
3. Determine the transaction price
The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products or services to the customer. To the extent the transaction price is variable, revenue is recognized at an amount equal to the consideration to which the Company expects to be entitled. This estimate includes customer sales incentives which are accounted for as a reduction to revenue and estimated using either the expected value method or the most likely amount method, depending on the nature of the program. The Company will adjust its consideration for any rebates if it is more likely than not that the rebate conditions will be met.
4. Allocate the transaction price to performance obligations in the contract
If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price for each performance obligation. The Company determines standalone selling price based on the price at which the performance obligation is sold separately.
In cases where there is no directly observable stand alone selling price, allowable estimation methods are used. For example for contracts involving non-recurring engineering, an expected cost plus margin approach has typically been adopted to estimate the standalone selling price.
5. Recognize revenue when or as the Company satisfies a performance obligation
For product sales, the Company generally satisfies performance obligations at a point in time, most often upon shipment of a product to the customer or delivery of the product to the customer. In the case of such point in time satisfaction of a performance obligation, revenue is recognized based on the transaction price at the time the related performance obligation is satisfied.
For service obligations, the Company generally recognizes revenue over time. The most common type of service obligation encountered by the Company is an arrangement involving non-recurring engineering in which service revenue is typically recognized over time under either the time and material practical expedient, as the Company has a right to consideration from a customer, in an amount that corresponds directly with the value to the customer of the Company's performance completed to date, or under the output method, for example using contract-specific milestones or other objective measures of progress.
Disaggregation of Revenue
Revenue is classified based on the location of where the product is manufactured. For additional information on the disaggregated revenues by geographical region, see Note R, "Segments and Geographic Information."

NOTE D— Leases
The Company leases space under non-cancellable operating leases for manufacturing facilities, research and development offices and certain storage facilities and apartments. These leases do not contain contingent rent provisions. The Company also leases certain machinery, office equipment and a vehicle under operating leases. The Company determines if an arrangement is or contains a lease at contract inception. Many of its leases include both lease (e.g. fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g. common-area or other maintenance costs) which are accounted for as a single lease component as the Company has elected the practical expedient to group lease and non-lease components for all leases. Several of the leases include one or more options to renew which have been assessed and either included or excluded from the calculation of the lease liability of the right-of-use ("ROU") asset based on management’s intentions and individual fact patterns. Several warehouses and apartments have non-cancellable lease terms of less than one-year and therefore, the Company has elected the practical expedient to exclude these short-term leases from its ROU asset and lease liabilities.

On September 19, 2025, the Company entered into a Lease Agreement with Coleman Logistics Assets LLC ("Coleman"), pursuant to which the Company will lease approximately
Although the lease agreement was executed prior to December 31, 2025, the lease had not yet commenced as of that date, as Coleman is currently completing required improvements to the leased premises. The lease will commence in 2026, at which time the Company will recognize a ROU asset and a corresponding lease liability on its consolidated balance sheet. The total undiscounted lease payments over the initial lease term are approximately $
As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Based on the applicable lease terms and current economic environment, the Company applies a location approach for determining the incremental borrowing rate.
Lease expense is included under general and administrative expenses and was $

Convertible senior notes are included in the denominator as if it were converted at the beginning of the period or, if issued during the period, at the time of issuance. In periods with net losses, normally dilutive shares become anti-dilutive. Therefore, basic and dilutive earnings per share are the same.

The 2026 Notes bears interest at a rate of 5.250% per year and will pay interest semi-annually in arrears on June 15 and December 15 of each year, beginning on June 15, 2024. The 2026 Notes will mature on December 15, 2026, unless earlier converted, redeemed or repurchased in accordance with their terms.
On December 18, 2024, the Company entered into exchange agreements with certain holders of the 2026 Notes to exchange approximately $

The conversion rate for the 2030 Notes is
The 2030 Notes will be redeemable, in whole or in part (subject to certain limitations described in the Indenture), at the Company’s option at any time, and from time to time, on or after January 15, 2027 and on or before the 40th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the 2030 Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of the Common Stock exceeds
In addition, the 2030 Notes will be redeemable, in whole or in part, at the Company’s option at any time, and from time to time, on or before the 40th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the 2030 Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date (subject to the right of a holder of 2030 Notes as of the close of business on a record date to receive the related interest payment on the corresponding interest payment date), if the “Specified Divestiture” (as defined in the Indenture) is completed.
Calling any 2030 Note for redemption will constitute a "Make-Whole Fundamental Change" (as defined in the Indenture) with respect to that 2030 Note, in which case the conversion rate applicable to the conversion of that 2030 Note will be increased in certain circumstances if it is converted after it is called for redemption.
In addition, if the Specified Divestiture is completed, then unless the Company has previously elected to redeem all of the 2030 Notes, each holder of 2030 Notes will have the right to require the Company to repurchase its 2030 Notes for cash on a date of the Company’s choosing, which must be a business day that is no more than 35, nor less than 20, business days after the date the Company’s sends the related notice of Specified Divestiture. The repurchase price for a note tendered for such repurchase will be equal to the principal amount of the 2030 Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date (subject to the right of a holder of 2030 Notes as of the close of business on a record date to receive the related interest payment on the corresponding interest payment date).
Moreover, if the Company undergoes a fundamental change, as described in the Indenture, holders of the 2030 Notes may require the Company to repurchase for cash all or part of their 2030 Notes at a repurchase price equal to
Additionally, the 2030 Notes are subject to customary events of default. The 2030 Notes do not restrict the Company’s ability to incur debt or liens. No sinking fund is provided for the 2030 Notes. There are no guarantors of the 2030 Notes.
Pursuant to the guidance in ASC 815-40, Contracts in Entity’s Own Equity, the Company evaluated whether the conversion feature of the note needed to be bifurcated from the host instrument as a freestanding financial instrument. Under ASC 815-40, to qualify for equity classification (or non-bifurcation, if embedded) the instrument (or embedded feature) must be both (1) indexed to the issuer’s own stock and (2) meet the requirements of the equity classification guidance. Based upon the Company’s analysis, it was determined the conversion option is indexed to its own stock and also met all the criteria for equity classification. Accordingly, the conversion option is not required to be bifurcated from the host instrument as a derivative.
Pursuant to ASC 815-15, the Company further determined that the contingent redemption features in the 2030 Notes are not required to be bifurcated from the host contract and accounted for separately. Additionally, the Company then evaluated whether the conversion feature needed to be separately accounted for as an equity component under ASC 470-20, Debt with Conversion and Other Options, and determined that the additional premium was not substantial. Accordingly, that amount was recognized as a premium on the 2030 Notes.

Management assesses the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. A significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-year period ended December 31, 2025. Such objective evidence limits the ability to consider other subjective evidence, such as our projections for future growth.
On the basis of this evaluation, as of December 31, 2025 and December 31, 2024, a valuation allowance of $

The Company’s provision for income taxes in 2025 was lower than 2024 primarily due to the release of Valuation Allowance on the deferred tax assets of the Company’s wholly owned subsidiary, Global Technology, Inc. As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. As of December 31, 2025, in part because in the current year we achieved three years of cumulative pretax income in China, management determined that there is sufficient positive evidence to conclude that it is more likely than not that additional deferred taxes of $
The Company's provision for income taxes in 2024 was higher than 2023 primarily due to state taxes.
The Company’s wholly owned subsidiary, Prime World is a tax-exempt entity under the Income Tax Code of the British Virgin Islands.
The Company’s wholly owned subsidiary, Global Technology, Inc., has enjoyed preferential tax concessions in China as a national high-tech enterprise. In March 2007, China’s parliament enacted the PRC Enterprise Income Tax Law, or the EIT Law, under which, effective January 1, 2008, China adopted a uniform income tax rate of

The Company is subject to taxation in the United States and various states and foreign jurisdictions. The Company’s open tax years subject to examination in the U.S. federal and state jurisdictions are through 2024. To the extent allowed by law, the taxing authorities may have the right to examine prior periods where net operating losses or tax credits were generated and carried forward, and make adjustments up to the amount of the net operating loss or tax credit carryforward. The Company is subject to examination for tax years forward for various foreign jurisdictions.
On August 9, 2022, the Creating Helpful Incentives to Produce Semiconductors and Science Act, (the "CHIPS Act") was signed into law. Among other things, the CHIPS Act provides for refundable tax credits and certain other financial incentives to further investments in domestic manufacturing. At least a portion of our current and future capital expenditures and research and development costs will qualify for this credit, which benefits us by allowing us to net the credit received against our costs. This credit is accounted for outside of ASC 740 as a reduction to the depreciable basis of the assets used in operations and will not have an impact on our effective tax rate.
On July 4, 2025, legislation commonly referred to as the One Big Beautiful Bill Act (the “OBBBA”) was signed into law. Among other things, the OBBBA suspends the requirement to capitalize and amortize domestic research and development (R&D) expenditures for amounts paid or incurred in taxable years beginning after December 31, 2024 and before January 1, 2030. The OBBBA also permits taxpayers to elect to accelerate deductions for the remaining unamortized domestic R&D expenditures paid or incurred between January 1, 2022 and December 31, 2024 over a one- or two-year period. The Company elected to accelerated deductions with respect to unamortized domestic R&D expenditures capitalized in 2022, 2023, and 2024 as a deduction in 2025.
In addition, the OBBBA preserves a significant portion of the Inflation Reduction Act (IRA) clean energy tax credit framework but introduces certain limitations and additional diligence obligations for developers, investors, lenders, and credit purchasers, including a phaseout of the Clean Electricity Tax Credits and placed-in-service deadlines for certain wind and solar projects (Internal Revenue Code Sections 45Y and 48E). Based on the Company’s business profile and the limited applicability of these provisions to the Company, we do not currently expect these changes to have a material impact on our income tax provision or ETR. The OBBBA permanently extends 100% bonus depreciation for qualifying property placed in service after January 19, 2025. The Company does not intend to elect bonus depreciation and, as a result, does expect this provision to have a material impact on the Company’s income tax provision or effective tax rate. For tax years beginning after December 31, 2024, the OBBBA permanently restores the EBITDA-based calculation of adjusted taxable income (ATI) for purposes of the Section 163(j) business interest expense limitation (i.e., allowing addbacks for depreciation, amortization, and depletion in computing ATI). This change generally increases the amount of business interest expense that can be deducted and may reduce the amount of interest subject to carryforward.
The Company expects any earnings of foreign subsidiaries to be indefinitely invested outside the United States. As of December 31, 2025, however, the Company does not have any accumulated undistributed earnings generated by foreign subsidiaries and has estimated that its tax basis in foreign subsidiaries exceeds its book basis. The Company has concluded that no deferred tax asset (DTA) should be recorded because at the present time it does not expect that the temporary book-tax basis difference that would create this DTA will reverse in the foreseeable future.
