Tower Semiconductor Ltd. is a pure-play independent specialty foundry dedicated to providing high-value, high-quality, processed wafers to customers for their end products, and does not offer products of its own. The semiconductor industry is characterized by rapid change, including rapid technological developments, evolving industry standards, changes in customer and end-user requirements, frequent new product introductions and enhancements, and short product life cycles with declining prices as products mature. The industry has historically been characterized as highly cyclical, both seasonally and over the long term, cycling through periods of weak demand, excess capacity, excess inventory, and price pressure, as well as periods of strong demand, full capacity utilization, and wafer shortages that command higher selling prices. Foundry services are used by nearly all major semiconductor companies in the world, including integrated device manufacturers, as part of a dual-source, risk-diversification and cost effectiveness strategy. The company operates as a specialty foundry focused on high-growth specialized markets, including silicon photonics for AI and data center communications, RF for smartphones, IoT, infrastructure communications, power management and CMOS image sensors for industrial, automotive, medical, and consumer end markets.
The company competes most directly in the specialty segment with foundries such as GlobalFoundries (mainly in the RF space), Vanguard Semiconductor, DongBu, X-Fab, and Hua Hong Semiconductor. It also competes in certain areas with pure-play, advanced technology node-driven foundry service providers that also provide specialty technologies, such as Taiwan Semiconductor Manufacturing Corporation (TSMC), United Microelectronics Corporation (UMC), and Semiconductor Manufacturing International Corp. (SMIC). Many competitors may have one or more competitive advantages, including greater capacity, a more diverse and established customer base, greater financial, sales, marketing, distribution and other resources, governmental funding or support, better cost structure, and/or better operational performance. The company aims to compete primarily on the basis of advanced specialty analog/mixed-signal technology, research and development, breadth of process offerings, production quality, technical support, and its design and engineering services. The company believes its highly differentiated specialty offering and proven track record in analog/mixed-signal markets, as well as in the Silicon Photonics market, enable it to effectively compete with larger foundry service providers.
The company generates revenue principally from providing customers with manufacturing services performed over wafers processed in its various fabrications, as well as revenue from design and technology support services. Wafer sales typically contain a single performance obligation that is fulfilled on the date of delivery and recognized at a point in time, which is upon shipment of the company's products to unaffiliated customers, depending on shipping terms stipulated in the contract. The primary customers of its foundry and design services are fabless semiconductor companies and integrated device manufacturers (including module integrators). The company prices its products on a per-wafer basis, taking into account the unique value of its technology, its ability to enable customers to differentiate their products, the complexity of the technology, prevailing market conditions, volume forecasts, the strength and history of relationships with the customer and its current capacity utilization.
The company currently offers process technology geometries of 0.35, 0.18, 0.16 and 0.13-micron on 200-mm wafers and 65 nanometer on 300-mm wafers.

It has developed a highly competitive silicon backplane technology for the OLEDoS (OLED on Silicon) market, primarily targeting the VR and AR sectors.
For the year ended December 31, 2025, 11% of revenues were generated from NTCJ, 39% of revenues were derived from an additional seven customers, each of which generated between 4% to 7% of revenues, and the remaining 50% of revenues were derived from many other smaller customers. For the year ended December 31, 2024, 13% of revenues were derived from NTCJ, 27% of revenues were derived from an additional four customers, each of which generated between 3% to 11% of revenues, and the remaining 60% of revenues were derived from many other smaller customers. The geographical distribution of net revenues for the year ended December 31, 2025 was 42% from the United States, 13% from Japan, 39% from Asia excluding Japan, and 6% from Europe. For the year ended December 31, 2024, the geographical distribution was 42% from the United States, 16% from Japan, 33% from Asia excluding Japan, and 9% from Europe.
During the last two years, the company initiated plans to invest an aggregate of $920 million in capital expenditures (primarily machinery and facilities), mainly to expand its silicon photonics (SiPho) and silicon germanium (SiGe) capacity and capabilities, as well as to enhance its power, next-generation and other capacity. In March 2026, the company signed an agreement for the strategic restructuring of its Japan operations, under which Tower will take full ownership of Fab 7, to be held through a wholly owned Japanese subsidiary of Tower, while NTCJ will take full ownership of Fab 5. The transaction is targeted to close on April 1, 2027, subject to the satisfaction of customary closing conditions and receipt of applicable regulatory approvals. Contingent upon subsidy approval from Japan's Ministry of Economy, Trade and Industry (METI) following the formal application, and subject to other considerations such as funding, permits and the engagement of contractors and equipment vendors, Tower's Japanese subsidiary may purchase the adjacent land on pre-agreed terms between Tower and NTCJ, which would be used for a potential new fab shell build-out in order to significantly expand its 300mm capacity and capabilities. During 2025, in response to anticipated changes in market dynamics and customer demand, the company discontinued operations at Fab 1 and consolidated certain flows into Fab 2. In September 2023, Tower and Intel signed an agreement under which Intel undertook to build a capacity corridor at Tower's instruction, to enable Intel to manufacture wafers for Tower's customers at Intel's 300mm facility in New Mexico, U.S.; Intel expressed its intention not to perform under the agreement, and the parties are presently in a mediation process. In March 2026, GlobalFoundries filed three lawsuits against the Company in the U.S. International Trade Commission and the U.S. District Court for the Western District of Texas, alleging infringement of certain of its patents; the Company disputes these claims.
Revenue for the year ended December 31, 2025 amounted to $1,566.1 million, as compared to $1,436.1 million for the year ended December 31, 2024, reflecting a $130.0 million, or 9%, year-over-year revenue increase. Gross profit for the year ended December 31, 2025 amounted to $363.9 million, as compared to $339.4 million for the year ended December 31, 2024. Operating profit for the year ended December 31, 2025 amounted to $194.2 million, as compared to $191.3 million for the year ended December 31, 2024. Net profit for the year ended December 31, 2025 amounted to $218.8 million, as compared to $207.2 million for the year ended December 31, 2024. Net profit attributable to the Company for the year ended December 31, 2025 amounted to $220.5 million, as compared to $207.9 million for the year ended December 31, 2024. As of December 31, 2025, the company had an aggregate of $235.4 million in cash and cash equivalents, as compared to $271.9 million as of December 31, 2024.
A key growth vector is the expansion of silicon photonics (SiPho) and silicon germanium (SiGe) capacity and capabilities. During the last two years, the company initiated plans to invest an aggregate of $920 million in capital expenditures (primarily machinery and facilities), primarily to expand SiPho and SiGe capacity at Fabs 2, 3, 7 and 9, as well as to enhance power next-generation and other capacity. Specifically with respect to SiPho, during 2026, the company has engaged with certain customers for committed capacity reservation through 2028 in exchange for prepayment received and to be received, which would be credited to them against their future purchases. The company is ramping its latest 1.6Tb/s platform into high-volume production and is developing and prototyping various advanced technologies aimed at a next-generation 3.2Tb/s platform, as well as co-packaged optics (CPO) for the future. These technologies include wafer-to-wafer bonding, lasers (including DWDM lasers), III-V modulators and TSVs, all embedded in the SiPho chip.
Another major growth vector is the potential significant expansion of 300mm capacity and capabilities in Japan. Contingent upon subsidy approval from Japan's Ministry of Economy, Trade and Industry (METI) following the formal application, and subject to other considerations such as funding, permits and the engagement of contractors and equipment vendors, Tower's Japanese subsidiary may purchase the adjacent land on pre-agreed terms between Tower and NTCJ, which would be used for a potential new fab shell build-out in order to significantly expand its 300mm capacity and capabilities, through the purchase of machinery and cleanroom facilities, and related investments. The necessary capital to be funded in part by the company, METI and other cash sources, which may consist of equity investments and/or debt vehicles, or a combination thereof. In March 2026, the company signed an agreement for the strategic restructuring of its Japan operations, under which Tower will take full ownership of Fab 7, to be held through a wholly owned Japanese subsidiary of Tower, while NTCJ will take full ownership of Fab 5. The transaction is targeted to close on April 1, 2027, subject to the satisfaction of customary closing conditions and receipt of applicable regulatory approvals.
The company's gross and operating margin is influenced by various factors, including market demand for semiconductor wafers, pricing changes, shipment volumes, new product introductions, changes in product mix, changes in the purchase price of raw materials, and yields. A large portion of total cost is comprised of fixed costs, so during periods of low utilization, reduced revenues may not cover all costs. The ramp-up of new capacity, where fixed costs are incurred upon the start of operations while gradually ramping up utilization, causes a decrease in profit margins. The company expects that the average selling prices of its products will decline as they mature and will seek to offset this effect by reducing operating costs and introducing new and higher value-add products.
The company has invested, and intends to continue to invest, in expanding its capacity, developing products to support its growth, and expanding its infrastructure. This includes the $920 million capital expenditure plan to expand SiPho and SiGe capacity at Fabs 2, 3, 7 and 9, as well as to enhance power next-generation and other capacity. The company also invested in equipment for the Agrate, Italy facility (Fab 10), where the comprehensive qualification process was completed during 2024, followed by the commencement of volume production and operations, managed by ST. Capital expenditures in 2025 and 2024 were $436 million and $432 million, respectively, net of proceeds from the sale of equipment and fixed assets of $8 million and $5 million, respectively. As of December 31, 2025, the company employed 5,316 employees, compared to 5,359 as of December 31, 2024.
Research and development expenses for the years ended December 31, 2025, 2024 and 2023 were $86.5 million, $79.4 million and $79.8 million, respectively, net of government participation of $1.0 million, $0.3 million and $0.5 million, respectively. The company plans to continue to invest significantly in research and development activities in order to develop advanced process technologies for new applications. The company does not anticipate paying dividends in the foreseeable future, intending to use future cash and earnings, along with its existing cash balance and deposits, to finance its growth and acquisition strategy, capacity expansion, ongoing operations, and other business and operational needs. The company may, however, use its existing cash balance and/or future cash earnings to execute share repurchases.
A structural headwind is the potential for over-demand for foundry services to result in operational bottlenecks and a loss of customers and revenues. From time to time, in periods during which demand exceeds capacity and the company experiences high utilization rates, it may be unable to fulfill customer demand in whole or in part, in a timely manner or at all, despite commitments under supply agreements and customer prepayment arrangements. Another headwind is the cyclical nature of the semiconductor industry and the volatility of the markets served by customers. Any significant decrease in demand for applications, devices or products may significantly decrease revenue and margins due to lower demand for wafers and/or lower selling prices per wafer. The company also faces risks related to its international operations, including JPY and NIS fluctuations against the USD, the burden and cost of compliance with foreign government regulation, tariffs, import and export restrictions, and general geopolitical risks.
A key execution risk management has explicitly flagged is the reliance on acquisitions, establishing new fabs and/or gaining additional capacity for growth, which involves risks and uncertainties that may adversely affect future revenues, business and operating results and may require raising funds. The company's $920 million capital expenditure plan and the potential new 300mm fab shell build-out in Japan are subject to risks including the inability to complete installation and qualification of machinery in a timely manner due to conflicts preventing vendors from arriving in Israel, and no assurance that customer demand will require full or high utilization of such machinery tools. The strategic restructuring of Japan operations is targeted to close on April 1, 2027, but there is no assurance that the transaction will close on that timeline, if at all. Additionally, there is no assurance that METI will grant the subsidy approval for the potential new fab shell build-out, that any subsidies will be in the amount and/or percentage of capital-expenditures as currently expected, or that the company will have sufficient funds to execute such plan.
Management's message emphasizes the company's position as a pure-play independent specialty foundry focused on high-growth specialized markets, with a strategy to establish leading market share by providing high-value, high-quality wafer foundry services. The key themes include a focus on expanding capacity and capabilities, particularly in silicon photonics (SiPho) and silicon germanium (SiGe), as evidenced by the $920 million capital expenditure plan initiated over the last two years. Management also highlights the strategic restructuring of Japan operations, under which Tower will take full ownership of Fab 7, targeted to close on April 1, 2027, and the potential for a new fab shell build-out in Japan contingent upon METI subsidy approval. The company's strategic priorities for the period ahead include executing on its capacity expansion plans, continuing to develop advanced process technologies such as the next-generation 3.2Tb/s SiPho platform and co-packaged optics, and navigating the strategic restructuring of its Japan operations to streamline its global footprint.
For the year ended December 31, 2025, total revenue was $1,566.1 million 1, compared to $1,436.1 million 2 for the year ended December 31, 2024. Net profit attributable to the Company was $220.5 million 3, compared to $207.9 million 4 in the prior year. Diluted earnings per share were $1.94 5 for 2025, versus $1.85 6 for 2024. Gross profit for 2025 was $363.9 million 7, compared to $339.4 million 8 in 2024, representing gross margins of 23.2% 9 and 23.6% 10, respectively. Operating profit for 2025 was $194.2 million 11, compared to $191.3 million 12 in 2024. Financing income, net, for 2025 was $56.7 million 13, compared to $50.8 million 14 in 2024. Other expense, net, for 2025 was $10.5 million 15, compared to $24.7 million 16 in 2024, which included mainly non-recurring, non-operational items. Income tax expense, net, for 2025 was $21.6 million 17, compared to $10.2 million 18 in 2024. As of December 31, 2025, the company had cash and cash equivalents of $235.4 million 19, compared to $271.9 million 20 as of December 31, 2024. Total short-term and long-term debt as of December 31, 2025 was $28.1 million 21 and $133.4 million 22, respectively. Net cash provided by operating activities for 2025 was $395.5 million 23. Capital expenditures, net of proceeds from sale of equipment, were $436 million 24 in 2025. The restructuring income, net, for the year ended December 31, 2024 amounted to $6.3 million 25, resulting from the reorganization and restructuring of Japan operations.
The company faces significant risks related to its $920 million capital expenditure plan to expand SiPho and SiGe capacity, as there is no assurance that it will complete installation and qualification of machinery in a timely manner due to conflicts preventing vendors from arriving in Israel, or that customer demand will require full utilization of such tools. The strategic restructuring of Japan operations, targeted to close on April 1, 2027, is subject to risks including failure to obtain regulatory approvals or close on that timeline. The potential new 300mm fab shell build-out in Japan is contingent upon METI subsidy approval, and there is no assurance that subsidies will be granted in the expected amount or that the company will have sufficient funds. The company's Fab 3 lease expires in 2030, and the landlord has asserted claims of a material non-curable breach, which could harm operations and financial results. The company is exposed to currency exchange rate fluctuations, with the USD depreciating against the NIS by 12.5% during 2025, which may increase costs of Israeli operations in USD terms.
