1. Business Results

(1) Analysis of Business Results

[1] Business results for the year ended March 31, 2012

Overall condition of business performance

During the year ended March 31, 2012, the severe conditions of the world economy deepened further due to the effects of the Great

East Japan Earthquake, financial and monetary problems in Europe, and a spontaneous decline in stock values worldwide. Within individual regions, in the US, personal consumption stopped growing at a low level and consumer prices were on an upward trend as unemployment rate remained high in the first half of the year. Although some improvements were seen after autumn, the recovery of the overall economy has been weak. Nonetheless, since the beginning of the new year, the jobs situation has improved, and the economy has gradually headed towards a recovery.

In Europe, personal consumption, which was sluggish in the first half of the year, stopped slowing down in Germany after autumn. Due to the financial crisis that started in Greece, business confidence worsened mainly in Southern Europe, and the average unemployment rate in the Euro zone rose to the highest level since 1997; thus, the overall economy was at a stagnated shape.

In Asia, during the first half of the year, the overall economy was robust as personal consumption was strong, but the pace of business expansion slowed down due to increasing anxiety over inflation and the effects of the Great East Japan Earthquake and flooding in

Thailand.

As for exports, though strong in the first half of the fiscal year, the pace of growth slowed down due to the deteriorating

European economies. In Japan, exports sank and personal consumption fell considerably due to decreased production of automobiles and other products, on account of the earthquake. The economy progressed along a recovery track after summer, but then again reverted towards a slowdown due to a stabilized but appreciated yen, while the jobs situation still remained bleak.

After mid-February, the economy gradually recovered due to the Bank of Japan’s monetary easing measures, an appreciation of the yen, and an adjustment to fallen stock prices.

Within the electronic industry, although smart phones and energy-saving related equipment, including LED lighting and solar power generators, enjoyed solid sales, inventory adjustment was prolonged due to a slowdown in production and sales of electronic products.

Market segments for audio visual equipment, game consoles, personal computers and flat-screen TVs remained in a distressed state, having been affected by the Great East Japan Earthquake and a worsening economy. In addition, flooding in Thailand cast a shadow over the production of automobiles and other electronic equipment.

Consequently, the electronic component industry suffered from these harsh conditions as well.

In individual sectors, in Japan, production volume of audio-visual equipment, including digital still cameras, game consoles, and automotive equipment drastically decreased due to the effects of supply chain interruptions and energy-saving measures that went to effect after f the Great East Japan Earthquake in March, 2011. After the summer, accompanied by the recovery from the earthquake, the overall economy tended to pick up, but did not achieve a full-fledged recovery. In addition, after autumn, the market of digital still cameras was affected by the flooding in Thailand, and sales of flat screen TVs considerably decreased as replacement demand spurred by the transition to digital terrestrial broadcasting had come to the end of its cycle. In Asia, the production of personal computers and flat-screen TVs decreased as it was affected by the Great East Japan Earthquake and the deteriorating European economies. Also, the production of digital still cameras and hard disks temporarily decreased due to the flooding in Thailand. Sales of smart phones and tablet PCs were strong.

In the US, the telecommunication infrastructure market and automotive market enjoyed robust sales, but the consumer-electronics market including TV sets, as well as the personal computer market remained sluggish.

In Europe, the consumer-electronics market remained in a slow state. Markets of automotive segments and telecommunication infrastructure, which were robust in the first half, entered into an adjustment phase due to a deteriorating interregional market in the second half of the year.

Under these circumstances, the ROHM Group exerted itself to strengthen production lines of automotive and electronic equipment, industrial instruments including medical equipment, digital home appliances, IT and mobile equipment, and also enhanced sales by increasing the number of FAEs (*1) at individual sales bases including China. In addition, the group continued to strengthen its sales structure for non-Japanese customers by establishing new sales companies in India and Brazil, and proceeding with efforts to form a structure capable of responding to changes in global markets.

The ROHM Group also aims to improve the global environment, by continuing to develop new power devices including SiC (silicon carbide) and other eco-friendly products. The group also started the world’s first mass-production of full-SiC power modules in March.

ROHM group has developed specific driver ICs for automotive LED rear lighting, head lights and daytime running lights, whose markets continue to expand. Furthermore, product lineups of the household LED lighting equipment including LED ceiling lights were drastically enhanced by AGLED Co., Ltd. (renamed from Maruzen Electric Co., Ltd. on October 1, 2011). Recently, the group started selling mini- krypton type LED light bulbs of 180 degree light distribution angle. In March, LED ceiling lights equipped as a standard feature with a “circadian lighting mode.”(*2) were offered to the market,, thus the group continued to focus on increasing sales of

LED-related devices and LED lighting whose markets are expanding rapidly as next-generation energy-saving lighting sources.

The ROHM Group also worked to augment business synergy, by strengthening partnership structures with LAPIS Semiconductor Co.,

Ltd. (renamed from OKI Semiconductor Co, Ltd. on October 1, 2011), which ROHM acquired in 2008, SiCrystal AG, a German SiC wafer manufacturer that ROHM purchased in 2009, and the US-based Kionix, Inc., which is a MEMS acceleration sensor (*3) supplier.

On the other hand, in the manufacturing arena, the ROHM Group was forced to temporarily suspend operations at the two strongholds of Miyagi and Ibaragi on account of the Great East Japan Earthquake, and at factories including two semiconductor assembly plants and a molding plant due to the flooding in Thailand. It is important to note that recovery from the damages caused by the flooding was

ROHM CO., LTD. (6963) Financial Report for the Year Ended March 31, 2012 much faster than anticipated and ROHM resumed full-volume supplies of products, earlier than initial estimates, from January 1, 2012, as a result of efforts by the entire group. However, unfortunately the whole process also attributed to a considerable decrease in sales.

Under these circumstances, consolidated net sales in the year ended March 31, 2012 were 304,652 million yen (a decrease of 10.9 percent from the year ended March 31, 2011), and operating profits were 6,352 million yen (a decrease of 80.6 percent from the year ended March 31, 2011), which were due to a stabilized but appreciated yen in this fiscal year. Ordinary income was 7,286 million yen

(a decrease of 72.8 percent from the year ended March 31, 2011).

Although a gain on insurance adjustments related to the flooding disaster in Thailand and the Great East Japan Earthquake was recorded, the net loss of the year ended March 31, 2012 was 16,106 million yen (net profit of 9,632 million yen for the year ended

March 31, 2011) as taxes increased as a result of an impairment of fixed assets and rounding off of deferred tax assets.

March 31, 2011), and segment losses amounted to 6,665 million yen (segment profits of 6,599 million yen recorded in the year ended

March 31, 2011).

In the digital audio and visual equipment segments, system power source ICs for digital still cameras enjoyed robust sales, but lens controller driver ICs, which experienced growth in the first half of the year, slowed down after January. For flat-screen TVs, as replacement demand slowed down due to the Great East Japan Earthquake and the switching to terrestrial digital broadcasting after the summer, power source ICs, LED backlight drivers, and speaker amplifiers marked a sizable drop in sales.

The sales of timing controllers for panels were sluggish in the first half of the year, but increased right after the new calendar year. In the mobile phone market, although illumination and proximity sensor ICs enjoyed strong sales, the sales of LED driver ICs dropped, and the sales of system power source ICs, which were strong in the first half of the year, decreased after the new year.

In the personal computer category, sales of fan motor driver ICs and power supply ICs performed poorly. For the automotive components market, in the first half of the year, sales of power source ICs for engine control units deteriorated, but, after the summer, sales went on a positive trend thanks to a recovery from the effects of the Great East Japan Earthquake.

In the general-purpose equipment category, although stepping motor driver ICs (*4) continuously enjoyed strong sales, sales of

EEPROMs and LDO regulators (*5) temporarily slowed down due to the damage from the flooding in Thailand.

At LAPIS Semiconductor Co., Ltd., a ROHM Group company, sales of LCD driver ICs were strong, but sales of memory ICs for amusement fell off considerably.

With regards to production systems, ROHM continued efforts to improve efficiency in pre- and post-processes, and strengthen the supply system against risks such as disasters by sharing production lines with LAPIS Semiconductor Co., Ltd. .

Consolidated net sales for the year ended March 31, 2012 recorded 103,861 million yen (a decrease of 8.5 percent from the year ended

March 31, 2011), and segment profits were 11,616 million yen (a decrease of 39.0 percent from the year ended March 31, 2011).

In the diode and transistor categories, overall sales slowed down due to the effects of the Great East Japan Earthquake and the flooding in Thailand, and a sluggish flat screen TV market. Sales of high efficiency power MOSFETs, which were robust in the first half of the fiscal year, deteriorated after autumn.

In the light emitting diode category, blue LEDs, which had experienced weak sales, enjoyed a robust trend after the new year. Overall sales results were on a recovery path, but did not achieve considerable growth.

In the area of laser diodes, sales of dual wavelength pulsation lasers for CD/DVD (*6) and lasers for DVD moved towards recovery.

In addition, ROHM strengthened its lineup of SiC diode / transistor products, which the company began selling as next-generation high efficiency devices in 2010, and the group started mass-production of full SiC modules by modulizing these devices.

ROHM also continued to improve production efficiency at individual group factories in Thailand, the Philippines, and Tianjin, China, as well as making efforts to enhance the BCM (Business Continuity Management) structure.

*6. Dual wavelength pulsation laser for CD/DVD

March 31, 2011), and segment losses were 482 million yen (segment profits of 4,633 million yen recorded in the year ended March 31,

2011).

In the resistors category, sales of super-small 0402 size resistors greatly increased, but overall sales slowed down.

In the tantalum capacitor category, sales decreased due to the effects of the flooding in Thailand.

In the module product category, as the result of enhancing product line up of LED lighting module products, which have been garnering attention, sales of power modules used in LED lighting and infrared reception modules for remote control steadily increased.

Demand for lighting products (LED lighting) also increased as demand for energy-saving products drastically increased for straight tube type LED lights. Consequently, the sales were on the rise.

In the sensor category, sales of proximity sensors were strong as smart phones enjoyed strong sales.

In the print head category, sales were sluggish because of adjustments continuing in the mini-printer market.

In the LED display category, as the existing mobile phone market was sluggish, sales of mainly dot-matrix displays slowed down.

In medical segments, micro blood testing systems started seeing an increase in sales after autumn in partnership with Arkray, Inc., a company that manufactures and sells medical equipment.

In the area of production systems, the ROHM Group continued efforts to strengthen production management systems and BCM structure, to improve production efficiency, and to reduce costs at a group factory in Dalian, China.

The net sales mentioned above are sales to external customers.

[2] Prospects for the Next Fiscal Year

Overall conditions concerning the performance prospects for the next fiscal year

In regards to the world economy, the US economy is seeing a recovery trend, but its resilience is weak. European economies remain in a volatile state as the financial crisis continues to smolder. In the electronics industry, the flat screen TVs market, which greatly decreased, seems to have at last gotten off the bottom, but did not reach to a full-fledged recover. We cannot help judging that the market still remains in a severe state.

The ROHM Group continues to develop new products that fit market needs, and improve new product lineups, and especially develop products in new fields and launch them on markets in a timely manner, to note SiC devices, sensor devises and LED related devices.

The group also continued to make utmost efforts to increase sales by expanding sales in the automotive and industrial equipment markets where further market growth is expected, strengthen our customer support system in overseas markets, and restructure production systems and cost reduction efforts, thus we are working to improve performance and corporate values.

With these conditions in mind, consolidated business result forecast throughout the fiscal year is as follows.

(2) Financial Analysis

Analysis on status of assets, liabilities, net assets and cash flow

During the fiscal year ended March 31, 2012, total assets decreased by 22,662 million yen from the previous fiscal year and amounted to 737,326 million yen. The main factors behind the decrease are as follows: cash and time deposits decreased by 19,087 million yen, intangible fixed assets decreased by 16,615 million yen, and securities decreased by 12,476 million yen, respectively, while liquidity assets increased by 30,709 million yen (of which accrued insurance increased 29,504 million yen).

Liabilities increased by 11,837 million yen from the previous fiscal year and amounted to 103,046 million yen. The main cause was our accounts payable increasing by 6,682 million yen.

Net assets decreased by 34,498 million yen from the previous fiscal year and amounted to 634,280 million yen. The main causes behind were a decrease in owners’ equity by 26,353 million yen and foreign currency translation adjustments by 4,417 million yen, respectively.

Consequently, equity ratio decreased from the 87.7 percent from the previous fiscal year to 86.0 percent.

The cash flow status in the year ended March 31, 2012 is as follows.

Cash flow from operating activities recorded a decrease of 26,699 million yen, which amounts to a plus of 36,858 million yen (a plus of 63,557 million yen in the year ended March 31, 2011). This is mainly attributable to certain negative factors in that the net profit before tax changed to a loss and gains on insurance claims, which did not incur in the previous year, were earned, and to certain positive factors in that accrued losses increased and insurance payments accrued in this term, which did not incur in the previous year.

Cash flow from investment activities recorded a minus of 45,788 million yen (a minus of 52,985 million yen in the year ended March

31, 2011) by decrease in expenses 7,197 million yen. This is mainly attributable to time deposits changing from an increase to a decrease, which worked as a positive factor, and expenses increasing due to purchase of subsidiary stocks, which worked as a negative factor.

Cash flow from financial activities decreased by 13,940 million yen (a minus of 24,434 million yen in the year ended March 31, 2011) and recorded a minus of 10,494 million yen in the year ended March 31, 2012. It was mainly due to the positive effects of a decrease in expenses due to the acquisition of own shares.

As a result of adding a decrease in exchange rate changes of 2,551 million yen, cash and cash equivalents decreased by 21,976 million yen from the previous fiscal year, and amounted to 208,745 million yen.

Plant and equipment investment of 62,000 million yen and depreciation of 46,200 million yen are scheduled as events with potential to significantly affect cash flow in the next fiscal year.

ROHM CO., LTD. (6963) Financial Report for the Year Ended March 31, 2012

(3) Basic Policy for Profit Distribution for the Year Ended March 31, 2012 and Year Ending March 31, 2013

[1] Basic Policy for Profit Distribution

In profit distribution to shareholders, ROHM is implementing actions in order to meet shareholders’ expectations for improving future value of the Company, by thoroughly considering the Company’s business results, financial status, and funding demands for business investment.

Under the global-scale restructuring and shakeout of the semiconductor industries, ROHM aggressively infuses funds to necessary capital investments and M&A to win out over competition, and strives to improve business performance from a long-term perspective, in order to live up to the expectations of shareholders.

On the other hand, from the long-term viewpoint of making continuous improvements to corporate value and ensuring stable and continuous payment of dividends, ROHM will make utmost efforts to stably pay dividends and maintain business performance and cash flow.

The world economy is expected to remain unstable for a while. In addition, due to the effects of the Great East Japan Earthquake and the flooding in Thailand, the electronics market still remains in a sluggish state. In the semiconductor industries, market growth in the mid- to long-term can be expected alongside further development of informatization despite such negative effects. However, global competition will intensify. The group is conducting company-wide efforts to enhance its corporate value through investment in cash reserves and generated cash flows both carefully and effectively, and ensure its manufacturing facilities are equipped with the proper equipment required to enhance its developmental and technological expertise. ROHM’s competitiveness is based on its expertise in technology, which leads to joint ventures and company acquisitions that ensure attractive returns. This allows ROHM to improve its net income per share (EPS) and return on equity (ROE).

[2] Profit Distribution for the Year Ended March 31, 2012

In consideration of obligations to provide a return to shareholders, the performance for this fiscal year (ended March 31, 2012), and future capital requirements, the year-end dividend will be 30 yen per share. As a result, the annual dividend, with 30 yen per share added as an interim dividend, is scheduled to be 60 yen per share.

[3] Schedule of Profit Distribution for the Year Ending March 31, 2013

Profit distributions for the year ending March 31, 2013 are scheduled, in consideration of performance for the next fiscal year and cash flow status, at 30 yen per share as an interim dividend and 30 yen per share as a year-end dividend, totaling 60 yen.

[4] Retirement of Treasury Stock

The ROHM Group considers the maximum treasury stock holdings to be 5 percent of the total outstanding shares, and, in principle, any amount beyond this limit shall be retired at the end of every fiscal year. The group continuously possesses treasury stocks on hand in order to secure management flexibility by utilizing them for merger and acquisition activity and other needs as required.

(4) Risk concerning the Company’s Businesses

The following are risks that may have a significant impact on the financial status and operating results of the ROHM Group.

[1] Risks Associated with Market Changes

The semiconductor industry and electronics component industry are subject to sharp, abrupt changes in market conditions, due to factors such as the tendency of end-set manufacturers in adjusting production according to the sales status of electronic products, as well as competition in prices and technology development. Prices are especially susceptible to sudden drops according to the supply-demand relationship, while competition from emerging Asian manufacturers tends to cause instability with regard to maintaining and increasing sales and procuring profits.

- 6 -

ROHM CO., LTD. (6963) Financial Report for the Year Ended March 31, 2012

[2] Exchange Risks

The ROHM Group has expanded its stronghold in global development, production, and sales; meaning the financial statements prepared in each local currency are converted into the Japanese yen in order to prepare consolidated financial statements. Accordingly, even if the values in local currencies remain the same, the profits and losses on the consolidated financial statement may be affected because of the exchange rates at the time of conversion.

The ROHM Group, while conducting production activities in Japan and Asian countries, sells its products in Japan, Asia, the U.S., and

Europe. This means different currencies are used between production and sales bases and consequently exchange rate fluctuations exert a continual influence on ROHM. Generally, a strong Japanese yen conversion adversely affects our business performance, while a weak yen conversion has a favorable impact.

[3] Risks of Product Defects

As stated in the Company Mission, the ROHM Group places top priority on quality, and produces products subject to stringent quality control standards. However, this does not guarantee that it never produces defective products or that it will never be liable to compensate buyers for product defects. If a buyer should make a claim for defects with regard to ROHM products, company performance might be adversely affected.

[4] Legal Risks

In order to manufacture products distinguished from those of other companies, the ROHM Group develops various new technologies and know-how, and produces and sells products worldwide based on these proprietary technologies. The ROHM Group has a division that specializes in the strict supervision of in-house activities so as to ensure that the technologies and know-how used by the Group do not infringe on the intellectual property rights of other companies such as patent rights. In addition, in all business fields in which the

ROHM Group is involved, the Group complies with all relevant laws and regulations with respect to the utilization and handling of exhaust air, drainage, harmful materials, waste treatment, surveys on soil/underground water pollution, and protection of the environment, health, and safety. However, the Group may incur legal responsibilities in this respect due to unexpected events, possibly having an adverse influence on business results.

[5] Natural Disasters and Geopolitical Risks

The ROHM Group performs development, manufacturing, and sales activities not only in Japan, but also worldwide. To diversify the risks, the Group locates production lines at different bases as a countermeasure. However, these production bases may be damaged due to earthquake, typhoon, flooding, and other natural disasters, or political uncertainty or international conflicts. Business results could be adversely affected by stalled product supply or considerable changes in electronics markets due to these disasters.

[6] Mergers and Acquisitions Risks

The ROHM Group, taking into account future business prospects, considers it necessary to investigate and implement mergers and acquisitions worldwide with a focus on entering new fields that are relevant to our existing business, and to always make utmost efforts to improve corporate value and broaden the size of business. In conducting mergers and acquisitions, we thoroughly study, review, and discuss before any acquisitions are made. Nonetheless, due to unexpected circumstances or significant changes in market forces after an acquisition, an acquired business may not progress as expected and we may suffer loss in some cases as a result.

[7] Other Risks and Corporate Risk Management System

In addition to the above-mentioned risks, there are various other risks that may influence the financial condition and business performance during business activities, such as risks related to logistics, material procurements, security leaks, and information systems. The ROHM Group set up a “Risk Management and BCM (Business Continuity Management) Committee” with the aim of averting these risks or minimizing such effects, by strengthening our risk management structure in ways that would consent business to continue.

3. Management Policies

(1) ROHM’s Basic Management Policy

ROHM believes that, in creating and improving perpetual and overall corporate status, added-values created by the company’s business activities should be allocated to all constituents, including shareholders, employees, and stakeholders in local communities in appropriate proportions, while retained earnings should be allotted to business investment and efforts to increase its competitive strength. To pursue this objective, it is also essential to obtain the understanding and cooperation of all those with a stake in the company’s performance. Making ROHM shares more attractive to investors has been one of the highest priorities of company management.

With these perspectives, ROHM has committed itself to developing market-leading products by focusing on high value-added system

ICs, Power Devices, LED related products, and Sensor devices for digital information technologies, mobile electronic equipment, industrial instruments and automotive components, where we can expect further market expansion. As a fundamental policy, ROHM pursues a stable supply of high quality, cost-competitive products in high volume through optimal utilization of its distinctive production technologies, and will consequently maintain a leading position in the global electronic components market.

(2) Referenced Corporate Performance Indices

ROHM is moving forward with various efforts, including the development of new products, while reinforcing sales operations to ensure profits. ROHM uses indices representing profits, such as EBITDA (*), as well as asset turnover ratio and plant and equipment investment efficiency. In addition, we are also striving to improve the net income per share (EPS) and financial efficiency, in order to enhance shareholder value.

* EBITDA (earnings before interest, taxes, depreciation, and amortization)

An index obtained by adding interest expenses and depreciation to income before income taxes and minority interests. It is commonly used to compare corporate earning power internationally.

(3) Mid- to Long-term Corporate Strategies

Amidst anticipated expansion in the electronics industry over the medium to long term, and parallel to further progress of informatization, global competition is expected to intensify, due mainly to broader demand fluctuations, ultimately mandating a realignment of the industry and an elimination of noncompetitive businesses.

To ensure stable growth and a strong, well-balanced financial position under these circumstances, a range of measures should be implemented: the development of original high value-added products, utilizing world-ranked advanced technologies, enhanced cost competitiveness, the establishment of a global production and distribution network that conveys high customer satisfaction in both domestic and overseas markets, as well as strengthening of sales and technical support for customers.

We also consider it extremely important to construct a concrete BCM system that maintains a stable supply chain in the event of natural disasters.

ROHM puts top priority on consistent development and production systems and the significance of quality, and devotes ceaseless effort to achieve these values.

As concrete measures, ROHM will enhance digital, analog, and integrated digital/analog technologies via continuous enhancements to our R&D system. For this purpose, ROHM is reinforcing customer support and in-house R&D system for further future growth with the development bases of the “Kyoto Technology Center”, “Yokohama Technology Center”, and “Optical Device Research Center” at the core of technological enhancement.

University in China; joint efforts with the Semiconductor Industry Research Institute of Japan—a think-tank of the Japanese semiconductor industry; and participation in other Japanese national leading-edge R&D projects that integrate industry-government-academia expertise. ROHM is also promoting partnerships with other companies whenever necessary to complement its technologies and consequently improve the efficiency of its R&D activities. Furthermore, ROHM is advancing with research and development for the next generation by moving forward with the development of using SiC substrates, which are expected to be far superior in terms of voltage endurance, high electric current, and low-loss to semiconductor devices made with conventional silicon substrates, and will proceed with the introduction of these devices to the market. At the same time, ROHM will move into new fields and technologies including bio-related business for medical related fields. In addition, the company is expanding into new fields and technologies by enhancing the lineups of biochips for the medical equipment industry and developing non-volatile logic ICs that nullify power consumption when on standby. ROHM makes the utmost efforts to build partnerships with SiCrystal AG, a

SiC wafers manufacturer in Germany, and Kionix, Inc. in the US, a supplier of MEMS acceleration sensors, which we acquired in

2009, as well as strengthening lineups of sensor related products via internal development. In addition, ROHM will enrich its product lineup for LED products including LED lighting, peripheral LED devices that are mounted in LED lighting, and LED driver ICs.

At production bases, ROHM is responding to global competition in the industry by enhancing its cost competitiveness and supply system to achieve global success. As concrete schemes, in the front-end process centered on domestic group factories, ROHM is advancing with the enlargement and miniaturization of wafers, while in the back-end process - focused on overseas group factories,

ROHM is working to improve production efficiency and establish a prompt supply system of new high quality products globally.

By focusing first and foremost on quality not only in manufacturing operations but also in the field of technological development including IC design and development of manufacturing technologies, the ROHM will extend its efforts group-wide to enhance product reliability. ROHM will also continue to produce components such as wafers, photomasks, and lead frames in-house, develop products

ROHM CO., LTD. (6963) Financial Report for the Year Ended March 31, 2012 that exceed competitor products in terms of quality and reliability, and reduce lead times, ultimately improving its global competitiveness.

In addition, with a view to expanding the company’s share in growing overseas markets, ROHM not only consolidates design center networks in Europe, the USA, and Asia, but also strengthens sales, technology, and quality support systems for customers worldwide by increasing local design personnel and FAEs. To respond to increasing global needs for digitalization and standardization, the company makes the utmost efforts to reinforce the lineup of ASSPs (application-specific standard products) (*). At the same time,

ROHM is dedicated to restructuring and integrating corporate organizations both in and outside Japan, in order to continue improving its business efficiency and accelerate the decision-making process.

In regards to sales, ROHM exerts itself to enrich the organizational structure so as to rapidly respond to changes in global markets and enhance the sales system to non-Japanese customers by increasing sales strongholds in inland China, India, and Brazil.

In the area of environmental conservation, the ROHM Group will continue to establish and implement environmental management systems based on “ISO 14001” as well as develop new products that contribute to energy conservation such as low-power-consumption products. ROHM is committed at both domestic and overseas production bases to attaining zero-emission goals by promoting the recycling of waste and continuing to support “green” procurement and supply. In Australia, ROHM has promoted a tree-planting project as part of its efforts against global warming. Furthermore, ROHM swiftly responded to the RoHS

Directive, the European environmental regulations, and imposed analyses of toxic substances by acquiring accreditation of the

“ISO/IEC 17025” laboratory and undertaking business activities in consideration of global environmental protection.

As for CSR activities, ROHM signed the United Nations Global Compact (UNGC) in May 2011, and requested the ROHM Group as well as procurement partners to uphold universal principles related to “human rights,” “labor standards,” “the environment” and

“corruption prevention.” The group also was the first to introduce ISO 26000, an international standard for social responsibility, and promote CSR management within the scope of a global standard.

* ASSP (Application Specific Standard Product)

General-purpose ICs specializing in functions for specific fields. They are advantageous in that they serve as general-purpose components as well as support a broad base of customers rather than being limited to specific customers.

(4) Priority Issues

The world economy gradually moved toward recovery from the abrupt economic slowdown triggered by the financial crisis in the US in 2008. However, because of continuing tough employment environments in the individual regions, as well as the financial crisis in

Europe, pressure was newly put on the overall economy, thus it has not yet achieved a full-fledged recovery.

The electronics industry is expected to grow in the mid- to long-term due to increasing demand for digital home information equipment and more sophisticated automotive electronic control systems. However, worldwide economic deterioration, technological competition and price wars are expected to continuously intensify. These factors mandate the increasing necessity of a constant supply of internationally competitive, innovative and high quality products and technologies with sustained efforts toward comprehensive cost reduction efforts.

The ROHM Group had continued to use the “OKI” brand as a transitional measure regarding “OKI Semiconductor Co., Ltd.,” which

ROHM purchased in 2008. After its acquisition and the elapse of a certain period of time, their recognition as a member of the ROHM

Group increased. So, in October 2011, the company changed its name to “LAPIS Semiconductor Co., Ltd.” Furthermore, Maruzen

Electric Co., Ltd., a company that develops, manufactures, and sells lighting equipment was added to the ROHM Group in October

2011, and had its name changed to “AGLED Co., Ltd.” They are strengthening the lineup of household lighting products of the

“AGLED®” brand.

Under these circumstances, the ROHM Group will make utmost efforts in developing new products and technologies such as SiC related products including SBD (*1), DMOSFET (*2), and IPM (*3) and new technologies, chip sets for next-generation embedded processor by Intel in the US - through cooperation with LAPIS Semiconductor Co., Ltd., and LED lighting products. Such efforts, will promote the development and expansion of sales of eco-friendly products targeted at improving power conversion efficiency and power-saving devices in a variety of markets including automotive, flat-panel TVs, information and telecommunication, and mobile equipment markets.

ROHM expanded its sensor business through acquisition of Kionix, Inc. in the US, in 2009, The company also increased sales of LED lighting by way of cultivating new sales channels, thus strengthening efforts to develop new markets that will respond to business needs in the near future.

Furthermore, ROHM will take vigorous steps to enter different market segments such as the human health and fitness business based on bio-sensing via enhanced micro-fabrication technology it has cultivated, thus exerting company-wide efforts to synergize business resources to the fullest extent in order to further increase stock value and corporate value.

On the other hand, in order to keep pace with rapid changes in the global and Asian electronic components markets, and increase market share, ROHM will not only develop and disseminate new products but also continue with enhancements intended to strengthen sales structures for non-Japanese customers, by increasing sales bases in inland China and FAEs, and developing new sales companies set up in India and Brazil.

Regarding the effects of massive flooding in Thailand in October 2011, the ROHM Group was forced to temporarily suspend operations at two production bases and one molding plant. Afterwards, in regards to the recovery efforts, ROHM made the utmost efforts to minimize the effects on various fields of endeavor, with special consideration going to the recovery of production as the top priority issue. In addition, the group resumed full-volume supply on January 1, 2012 by recovering production via a substitute production system and outsourced consignment.

ROHM CO., LTD. (6963) Financial Report for the Year Ended March 31, 2012

(5) Note on Going Concern

No applicable items

(6) Major Items for the Preparations of Consolidated Financial Statements

Items regarding standards for accounting procedures

Standard for accounting important allowance

Liabilities for retirement benefits

In order to provide retirement benefits to employees, ROHM is allocating the allowance based on retirement liabilities and estimated amount for pension assets as of the end of the year ended March 31, 2012.

Actuarial gain and loss are amortized in the fiscal year following the fiscal year in which the gain or loss is recognized by the straight-line method over stated years that do not exceed the average remaining service period of eligible employees as of the relevant consolidated fiscal year (10 to 13 years).

Past service liability is calculated by the straight-line method, using a certain number of years (10 to 13 years) within the average remaining service period of the employee at the time of occurrence, and allotting it as costs.

Regarding matters other than those mentioned above, since there are no significant changes from the descriptions in the latest securities report (submitted on June 29, 2011), information other than that listed above has been omitted from this disclosure.

(7) Change in Indication Method

(Consolidated cash flow statement)

In the consolidated fiscal year ended March 31, 2011, “Expense accompanying purchase of subsidiary shares”, which was included in “Others” of “Investing Activities,” became more significant in terms of monetary value, therefore ROHM decided to record the amount independently from the current consolidated fiscal year. In order to reflect the change in posting method, the company has changed the sequence in consolidated financial statement.

As a result, -3,006 million yen, which was listed in “Others” in “Investing Activities” in the consolidated cash flow statement of the previous year, was changed to -601 million yen of “Expense accompanying purchase of subsidiary shares” and -2,405 million yen of

“Others.”

(8) Additional Information

(Accounting standards and implementation guidance on correction of accounting changes and errors)

Effective from the accounting changes and errors after the beginning of the current fiscal year, the group is applying the

“Accounting Standard for Accounting Changes and Error Corrections” (ASBJ Statement No.24 of December 4, 2009) and

“Guidance on Accounting Standard for Accounting Changes and Errors” (ASBJ Guidance No.24 of December 4, 2009).

(Segment information)

1. Segment information

(1) Overview of reportable segments

The reportable segments of the ROHM Group are units of the group for which separated financial information is available, and which is the subject of the periodical review by the board of directors for the purpose of deciding the distribution of management resources and evaluating business performance.

The ROHM Group is a comprehensive manufacturer of electronic components, and sets up operational divisions by individual product categories at its headquarters. Each operational division draws up comprehensive production plans and business strategies for both domestic and overseas operations, and develops global production activities. Therefore, from a management standpoint, the group attaches great importance to the supervision of profits and losses by operational segments organized as operational divisions of individual product categories. For this reason, the group is consolidating operational segments in consideration of characteristics of the products each operational division is manufacturing and similarities of production process, and setting up two reportable segments as “ICs” and “Discrete semiconductor devices”.

In the “ICs” segment, products such as analog ICs, logic ICs, memory ICs and ASICs are manufactured and foundry business operations are conducted.

Products manufactured in the “Discrete semiconductor devices” segment include diodes, transistors, light-emitting diodes, and laser diodes.

(2) Calculating method of amount of sales, profit or loss, asset, liabilities, and other items of individual segment information

Accounting processing for each reported operating segment is basically identical to accounting standards used for compiling consolidated financial statements.

Profits of reported segments are operating profits. “Internal sales between individual segments or amount transferred” are calculated based on market price.

Although assets of common categories such as sales and administrative expenses, are included in “Adjustments,” depreciation costs derived from these assets are allocated to individual segments according to in-house standards to calculate individual segment profits.
