ROHM CO., LTD. (6963) Financial Report for the Nine Months Ended December 31, 2025 2 1. Overview of Business Results and Financial Condition (1) Business Results General Overview of Business Performance During the nine months (April –December) ended December 31, 2025 , the economies of Japan and other countries gradually recovered, but uncertainty related to geopolitical risk, including that around U.S. trade policy, remained high, raising concerns about economic slowdown. In the electronics industry, the automotive market was weaker than originally forecast but remained firm. The industrial equipment market saw progress in clearing supply chain inventory buildup and has been recovering. In the consumer product market, demand for amusement -related products grew significantly. The computer and storage market was also firm, mainly in products for servers. Working within this business environment, the ROHM Group formulated its second Medium -Term Management Plan, “MOVING FORWARD to 2028, ” for the three -year period ending FY2028. In line with the plan, we are working to build a strong business foundation that is resilient to market fluctuations and improve profitability in preparation for future corporate expansion. Specifically, we are implementing structural reforms, such as reorganizing manufacturing sites, optimizing the business portfolio, and revising prices, and working to achieve profitability in the SiC business. Recently, we have been working to control increases in fixed costs by minimizing capital investment and negotiating price revisions to pass on rising raw material and other costs. As a result, net sales for the nine months ended December 31, 2025 increased by 7.2 % from the same period of the previous fiscal year to 369,515 million yen. This was due in part to a significant increase in revenue from the consumer product market, as well as an increase in sales in the automotive market. Operating profit came to 9,703 million yen, compared with operating loss of 11,080 million yen in the same period of the previous fiscal year. This mainly reflected the increase in net sales as well as a reduction in fixed costs due to structural reforms from last fiscal year. Ordinary profit came to 15,058 million yen, compared with ordinary profit of 316 million yen in the same period of the pervious fiscal year. This was due to a decrease in interest income at overseas subsidiaries and foreign exchange losses, despite the increase in operating profit. Profit attributable to owners of parent came to 14,822 million yen, compared with profit attributable to owners of parent of 210 million yen in the same period of the previous fiscal year. Moreover, EBITDA* was 51,266 million yen for the nine month s ended December 31, 2025 , up 1.6% from the same period of the previous fiscal year. * EBITDA (Earnings before interest, taxes, depreciation and amortization) An accounting metric widely used around the world to compare businesses in terms of earning power, calculated by adding interest and depreciation to a company’s pretax earnings. The ROHM Group simplifies the EBITDA calculation by adding back depreciation to operating profit. Overview of Performance by Segment Integrated Circuits (ICs) By market, in the automotive market, products for ADAS applications were in an adjustment phase, but sales of high-value-added products, mainly for body applications and xEVs (the generic name for electromotive vehicles such as hybrid electric vehicles, plug -in hybrid electric vehicles and fuel -cell electric vehicles), grew. As a result, overall sales increased year on year. The industrial equipment market continued to face challenging conditions. In contrast, in the consumer product market, sales for amusement -related products were firm, and in the computer and storage market, sales of products for business equipment recovered. As a result, consolidated net sales for the nine months ended December 31, 2025 were 169,360 million yen, up 8.6% from the same period of the previous fiscal year, and segment profit was 19,937 million yen, up 400.1%.

ROHM CO., LTD. (6963) Financial Report for the Nine Months Ended December 31, 2025 3 Discrete Semiconductor Devices By business, in SiC power devices, sales of products for xEVs in the automotive market were firm. In Si power devices, sales of products for the consumer product and industrial equipment markets were firm. Sales of general -purpose devices and LEDs improved, mainly in the area of products for the industrial equipment market. Sales of laser diodes to the computer and storage market increased. As a result, consolidated net sales for the nine months ended December 31, 2025 were 155,837 million yen, up 8.1% from the same period of the previous fiscal year, and segment loss was 16,488 million yen, compared with segment loss of 20,493 million yen in the same period of the previous fiscal year. Modules By business, sales of printheads for business equipment increased. In optical modules, sales of LED modules for automotive applications and sensors for smartphones increased. As a result, consolidated net sales for the nine months ended December 31, 2025 were 24,915 million yen, down 2.9% from the same period of the previous fiscal year, and segment profit was 3,011 million yen, up 11.1%. Others By business, sales of high-reliability shunt resistors and high-power resistors were strong, particularly in the automotive market and industrial equipment market. However, sales of general -purpose resistors declined year on year, primarily in the consumer product and automotive markets. As a result, consolidated net sales for the nine months ended December 31, 2025 were 19,401 million yen, up 2.3% from the same period of the previous fiscal year, and segment profit was 3,332 million yen, up 76.2%. Sales referenced in the “Overview of Performance by Segment” section above were to customers outside of the ROHM Group. (2) Financial Conditions At the end of the nine months ended December 31, 2025, total assets were 1, 449,943 million yen, an increase of 9,177 million yen from the end of the previous fiscal year, which can be largely explained by increases in cash and deposits and property, plant and equipment, despite decreases in investment securities and securities. Total liabilities were 523,780 million yen, a decrease of 27,329 million yen from the end of the previous fiscal year, which can be largely explained by decrease in accounts payable – other, despite increases in deferred tax liabilities and others in current liabilities. Total net assets were 9 26,162 million yen, a n increase of 36,507 million yen from the end of the previous fiscal year, which can be largely explained by increases in foreign currency translation adjustment and valuation difference on available-for-sale securities. As a result, the equity ratio increased to 63.8% from 61.7% at the end of the previous fiscal year. (3) Cash Flow Cash and cash equivalents (collectively, “Cash”) at the end of the nine months ended December 31, 2025 were 300,932 million yen, an increase of 6 5,965 million yen from the end of the previous fiscal year (an increase of 28,981 million yen during the same period of last fiscal year). Net increase (decrease) of Cash and contributing factors are as follows: [Net cash provided by (used in) operating activities] There were decreasing factors contributing to 22,445 million yen of profit before income taxes such as an increase in trade receivables. However, due to increasing factors such as depreciation, net cash resulted in an increase of 71,324

ROHM CO., LTD. (6963) Financial Report for the Nine Months Ended December 31, 2025 4 million yen compared to an increase of 68,485 million yen during the same period of last fiscal year. [Net cash provided by (used in) investing activities] Net cash from investing activities increased by 982 million yen compared to a decrease of 88,803 million yen during the same period of last fiscal year due to proceeds from sale and redemption of short -term and long -term investment securities, despite expenditures for purchase of property, plant and equipment. [Net cash provided by (used in) financing activities Net cash from financing activities decreased by 20,434 million yen compared to an increase of 39,398 million yen during the same period of last fiscal year mainly due to dividends paid. (4) Future Outlook The global economy is gradually improving overall, but geopolitical risks, including those related to U.S. trade policy, are rising, and the outlook remains unclear. The electronics industry will likely continue to benefit from the promotion of energy savings to combat climate change and help realize decarbonization , as well as firm capital investment for factory automation and digitalization around the world over the long term. Over the past few years, the rapid evolution and adoption of generative AI has fueled a significant increase in investment related to data centers, and demand for servers and storage is expanding rapidly. Consequently, the supply and demand for memory has become significantly tight, and concerns are growing about the impact on various markets. In the near term, within the automotive market, in light of the relatively quick resolution of recent halts in shipments from Chinese semiconductor manufacturers, global automobile production volume is expected to continue to see annual growth. In the computer and storage market, demand for products used in personal computers and servers is firm. In addition to the strength of the aforementioned markets, the weaker -than-forecast yen has also contributed to sales. As a result, net sales have been above the pace necessary to meet the plan for the fiscal year. However, in terms of profit, despite the increase in sales and impact of the weak yen, quality assurance -related costs in the SiC power device business have been up since the third quarter, negatively impacting profit for the fiscal year. However, these costs are only temporary, occurring during final adjustments for the adoption of products for mass -production in the automotive market, and improvement is expected in the coming fiscal year and beyond . Under these circumstances, we have revised our full -year consolidated earnings forecast for the fiscal year ending March 31, 2026, as shown below: Consolidated Financial Results Forecast (Billions of yen) Year ended March 31, 2025 Year ending March 31, 2026 (Estimates) Percentage Change from the Previous Year Net Sales 448.4 480.0 +7.0% Operating profit (loss) (40.0) 6.0 - Ordinary profit (loss) (29.6) 11.0 - Profit attributable to owners of parent (loss) (50.0) 10.0 -

Figures are based on an exchange rate of 1 USD to 153 JPY in the fourth quarter of the fiscal year. 2. ROHM Group has previously used the declining balance method as the depreciation method for tangible fixed assets, but has changed to the straight-line method from this fiscal year ending March 31, 2026. This change in depreciation method resulted in a decrease of 16,546 million yen in depreciation and an increase of 14,858 yen million in both operating profit and ordinary profit for the fiscal year ending March 31, 2026 compared to the previous method.

ROHM CO., LTD. (6963) Financial Report for the Nine Months Ended December 31, 2025 11 (4) Notes on Consolidated Quarterly Financial Statement (Changes in accounting policies that are difficult to distinguish from changes in accounting estimates) (Change in Depreciation Method for Tangible Fixed Assets) ROHM Group has previously used the declining balance method as the depreciation method for tangible fixed assets (excluding right-of-use assets), but we have changed to the straight-line method from the first quarter of the current fiscal year. Our Group's business structure has shifted from consumer to automotive applications, and in recent years, we have made large -scale capital investments in growth businesses to meet the growing demand for the automotive market. As a result of reviewing the actual use of fixed assets, we expect stable operation of tangible fixed assets in the future and have determined that straight-line depreciation more accurately reflects the actual use of tangible fixed assets. Due to this change in depreciation method, depreciation expense for the nine months ended December 31, 2025 decreased by 12,407 million yen compared to the previous method, and operating profit, ordinary profit, and quarterly profit before income taxes increased by 10,719 million yen.
