In 2020, ROHM's subsidiary SiCrystal GmbH entered into a multi-year supply agreement with STMicroelectronics for 150mm silicon carbide (SiC) substrate wafers, valued at over $120 million, which was expanded in 2024 to include larger volumes worth at least $230 million over the agreement period.^[79]^[80] This partnership supports the joint development and scaling of SiC technologies for automotive and industrial applications, leveraging SiCrystal's manufacturing in Nuremberg, Germany. Additionally, ROHM maintains ongoing industry-academia ties with Kyoto University through the ROHM Plaza, established to promote collaborative research on the physical properties of next-generation semiconductor devices and materials.^[81] In parallel, ROHM has pursued sustainability initiatives integrated into its R&D framework, emphasizing environmental responsibility and social impact. The company's Environmental Vision 2050 outlines a commitment to carbon neutrality by achieving virtually zero greenhouse gas emissions and 100% renewable energy usage by 2050, with interim targets including a 50.5% reduction in Scope 1 and 2 emissions by 2030 compared to FY2018 levels.^[82]^[83] To support this, ROHM has certified its goals under the Science Based Targets initiative (SBTi) at the 1.5°C level, focusing on energy-efficient product development such as SiC devices that contribute to downsizing and reduced power consumption in end applications.^[84] ROHM's waste management efforts in production align with its zero-emissions goal, achieving a consolidated recycling rate of 98.8% in FY2024, including high recovery of wafer production waste through resource recycling programs that target a recycling rate of 99.0% or higher on a worldwide consolidated basis by FY2030.^[85] The company has also prioritized compliance with the RoHS Directive since 2004 by transitioning to lead-free components across its portfolio, minimizing hazardous substances in semiconductors and optoelectronics to support global environmental standards.^[86] Complementing these environmental commitments, ROHM integrates diversity into its R&D workforce development, aiming to increase the global female manager ratio to 15% by 2025 and 20% by 2030 as part of broader initiatives to foster inclusive innovation and talent retention in engineering roles.^[85] These efforts are supported by collaborations with external bodies, such as membership in the UN Global Compact since 2011 and participation in the Responsible Business Alliance (RBA) to promote sustainable supply chains.^[87]

Financial Performance

Revenue and profitability trends

ROHM's revenue has exhibited significant fluctuations influenced by global semiconductor demand cycles and currency movements. In fiscal year 2017, net sales totaled ¥352 billion.^[88] By fiscal year 2023, semiconductors, including integrated circuits and discrete devices, accounted for approximately 80% of total sales, underscoring the company's core focus on this segment.^[89] The trailing twelve months as of September 2025 reached ¥461 billion, reflecting a recovery from earlier declines amid ongoing industry challenges.^[90] In recent performance, the first half of fiscal year 2026 (April to September 2025) saw net sales rise 5.3% year-over-year to ¥244.2 billion.^[91] Attributable profit surged 399% to ¥10.3 billion, driven by heightened demand for electric vehicle (EV) components, particularly silicon carbide (SiC) devices, alongside cost reduction measures such as adjusted depreciation methods that lowered fixed expenses.^[91]^[92] Following these results, ROHM revised its full-year FY2026 guidance to net sales of ¥460 billion and operating profit of ¥40 billion as of November 2025.^[93] Profitability metrics have varied with market conditions and operational efficiencies. The operating margin stood at 18.2% in fiscal year 2022, benefiting from strong demand and favorable exchange rates.^[94] However, it declined to -9.2% in fiscal year 2025 due to inventory adjustments and softer EV adoption amid economic headwinds.^[95] Return on equity (ROE) for fiscal year 2025 was -5.4%, reflecting the impact of net losses during the chip cycle downturn.^[96] For the first half of fiscal year 2026, the operating margin improved to 3.1%, signaling early recovery through cost controls.^[91] Key drivers of growth include the expansion of SiC technologies, which have helped offset supply shortages experienced in 2021–2022 by enabling higher-margin EV applications in markets like China and Europe.^[91]^[97] Additionally, yen depreciation has boosted export competitiveness through favorable translation effects.^[98] Challenges persist from global chip inventory gluts and volatile raw material costs, though strategic cost cuts and SiC investments position ROHM for improved margins in upcoming periods.^[91]

Market position and stock overview

ROHM Semiconductor holds a notable position in the global semiconductor industry, ranking among the top 40 companies by revenue as of 2025, with particular strengths in power devices and analog integrated circuits (ICs). The company commands approximately 1.1% of the worldwide analog IC market, placing it 17th among global players, driven by its focus on automotive and industrial applications.^[99] In power discretes, ROHM maintains a competitive edge through its expertise in silicon carbide (SiC) technologies, where its SiC product market share by volume exceeds 10% in key segments like automotive power modules, though overall SiC penetration remains below 20% amid growing demand for electric vehicles.^[100] Key competitors in the power semiconductor space include Infineon Technologies and ON Semiconductor, both of which lead in SiC and power modules for automotive and industrial uses, while ROHM differentiates through integrated SiC MOSFETs and cost-effective discretes. In analog ICs, ROHM faces rivalry from Texas Instruments, which dominates with broader portfolios in signal processing and power management. These dynamics position ROHM as a specialized mid-tier player, benefiting from Japan's robust supply chain but challenged by larger integrated device manufacturers.^[101]^[102] ROHM's stock, traded on the Tokyo Stock Exchange under ticker 6963, had a market capitalization of approximately ¥800 billion as of November 18, 2025, reflecting its mid-cap status in the sector. The forward price-to-earnings (P/E) ratio stood at approximately 12.6, indicating relative undervaluation compared to peers amid cyclical recovery, with a forward dividend yield of 2.49% based on an annual payout of ¥50 per share.^[103]^[104] The stock reached a 52-week high of ¥2,529 in late 2025, buoyed by positive first-half earnings that highlighted profit surges in power devices.^[103] Looking ahead, analysts project a consensus price target of ¥2,277 for the stock by mid-2026, supported by expected revenue growth to ¥473 billion, driven by the successful execution of ROHM's "Moving Forward to 2025" medium-term management plan, which emphasizes SiC expansion and operational efficiency. This outlook anticipates a 2.7% year-over-year sales increase in fiscal 2026, aligning with broader semiconductor demand revival in automotive and renewables.^[105]^[106]^[21]
