1. Operating and Financial Review and Prospects

(1) Analysis of Operating Results

1. Overview of Business Environment for the Nine Months Ended December 31, 2011

In the nine months ended December 31, 2011, the global economy weakened due to the financial crisis in Europe and its ramifications that had further deteriorating effects, and supply chains for various industries were disrupted again by the flooding in Thailand as they were returning to normal after being disrupted by the earthquake in northern Japan. As a result, production levels in many industries were adversely affected, further slowing the global economy, including the economies of developing countries.

We were adversely impacted by the supply chain disruptions caused by the earthquake in Japan, the appreciation of the Japanese yen and other Asian currencies, rising prices of rare earth and other raw materials, and the supply chain disruptions caused by the flooding in Thailand. We focused our group-wide resources on efforts to recover from the adverse impact based on our experience in improving our profit structure amid the post-Lehman shock recession, considering the recession an opportunity for improvement. As a result of the foregoing,

(1) We were severely affected by the flooding in Thailand as it caused our manufacturing facilities in Thailand, which represent more than 60% of our production capacity with respect to small precision motors for hard disk drives ("HDDs"), our core product line, to temporarily suspend operations. We promptly launched our recovery efforts in Thailand while augmenting the production capacity of, and transferring a portion of the manufacturing operations in Thailand to, our manufacturing facilities in the Philippines and China based on a new risk diversification policy. As a result, the total number of units of small precision motors for HDDs manufactured in the three months ended December 31, 2011 was approximately 70% of that in the three months ended September 30, 2011, and the total number of units of such motors sold in the three months ended December 31, 2011 was approximately 80% of that in the three months ended September 30, 2011. (The total number of units of small precision motors for HDDs manufactured in the month of December 2011 was approximately 90% of our record high for the month of December.)

(2) In this difficult business environment, our operating income and net income attributable to Nidec Corporation decreased approximately 35% and 12%, respectively, for the three months ended December 31, 2011 compared to the three months ended September 30, 2011, and our diluted earning per share decreased approximately 11% to ¥62.30 between the same periods. Our operating income and net income attributable to Nidec Corporation decreased approximately 28% and 22%, respectively, for the nine months ended December 31, 2011 compared to the nine months ended September 2010, and our diluted earning per share decreased approximately 24% to ¥214.87 between the same periods.

(3) We have made downward adjustments to our previously announced forecast for the fiscal year ending March 31, 2012, considering the adverse effects of the flooding in Thailand and other factors, while keeping our previously announced forecast of full-year dividends of ¥90 per share. As a result, our target ratio of dividend to diluted earning per share for the fiscal year ending March 31, 2012, has been revised to 30.9%.

2. Consolidated Operating Results

Consolidated Operating Results for the Nine Months Ended December 31, 2011 ("this nine-month period") Compared to the Nine Months Ended December 31, 2010 ("the previous nine-month period")

Consolidated net sales increased ¥4,706 million, or 0.9%, to ¥519,680 million for this nine-month period compared to the previous nine-month period. Operating income decreased ¥20,875 million, or 28.4%, to ¥52,691 million for this nine- month period compared to the previous nine-month period. Our operating income ratio for this nine-month period exceeded 10% at 10.1%. The average exchange rate between the U.S. dollar and the Japanese yen for this nine-month period was ¥79.01 to the dollar, which reflects the appreciation of the Japanese yen against the U.S. dollar of approximately ¥7.84, or 9%, compared to the previous nine-month period. The appreciation of the Japanese yen and other Asian currencies against the U.S. dollar had a negative effect on our net sales and operating income of approximately ¥28,500 million and ¥6,800 million, respectively, for this nine-month period compared to the previous nine-month period.

Income from continuing operations before income taxes decreased ¥14,266 million, or 23.3%, to ¥47,054 million for this nine-month period compared to the previous nine-month period. An approximately ¥7,200 million decrease in foreign exchange loss (mainly relating to translation of foreign currency-denominated assets) to approximately ¥4,200 million for this nine-month period from approximately ¥11,500 million for the previous nine-month period had a positive effect on our income from continuing operations before income taxes for this nine-month period.

Net income attributable to Nidec Corporation decreased ¥8,819 million, or 21.8%, to ¥31,654 million for this nine-month period compared to the previous nine-month period.

Operating Results by Product Category for This Nine-Month Period compared to the Previous Nine-Month Period

Small precision motors-

Net sales of small precision motors decreased approximately ¥18,100 million, or 7%, to ¥231,523 million for this nine-month period compared to the previous nine-month period. This was mainly due to the appreciation of the Japanese yen and other Asian currencies against the U.S. dollar and the negative impact of the flooding in Thailand, more than offsetting the positive effect of the sales of approximately ¥8,600 million at Nidec Seimitsu Corporation, which was newly consolidated on July 1, 2011. The appreciation of the Japanese yen and other Asian currencies against the U.S. dollar had a negative effect on our sales of small precision motors of approximately ¥20,700 million for this nine-month period compared to the previous nine-month period.

The number of units sold and sales of small precision motors for hard disk drives ("HDDs") decreased approximately 5% and 14% for this nine-month period compared to the previous nine-month period, respectively. This decrease was mainly due to the negative impact of the flooding in Thailand on our manufacturing facilities and supply chains for small precision motors for HDDs. Average unit prices of spindle motors decreased approximately 1% on a U.S. dollar basis and 10% on a Japanese yen basis for this nine-month period compared to the previous nine-month period, reflecting the 9% appreciation of the Japanese yen against the U.S. dollar. The number of units sold of spindle motors for 2.5-inch HDDs increased approximately 1% for this nine-month period compared to the previous nine-month period, although the number of units sold of spindle motors for 3.5-inch HDDs decreased approximately 11% for this nine-month period compared to the previous nine-month period. Sales of spindle motors for 2.5-inch and 3.5-inch HDDs decreased approximately 11% and 17%, respectively, for this nine-month period compared to the previous nine-month period, reflecting the negative impact of the appreciation of the Japanese yen against the U.S. dollar.

8

Net sales of other small precision brushless DC motors decreased approximately 1% for this nine-month period compared to the previous nine-month period. With respect to Nidec Corporation and its direct-line subsidiaries, sales of other small precision brushless DC motors decreased approximately 11% for this nine-month period compared to the previous nine-month period. The 11% decrease in net sales of other small precision brushless DC motors was mainly due to the 9% appreciation of the Japanese yen against the U.S. dollar and a 4% decrease in average unit price on a U.S. dollar basis resulting from a change in the product mix of our small precision DC motors for optical disk drives, although the number of units sold of other small precision brushless DC motors increased approximately 1% for this nine-month period compared to the previous nine-month period.

Net sales of brushless DC fans decreased approximately 10% for this nine-month period compared to the previous nine-month period. With respect to Nidec Corporation and its direct-line subsidiaries, sales of brushless DC fans decreased approximately 8% for this nine-month period compared to the previous nine-month period, while the number of units sold decreased approximately 2% for the same period. The main reason for the 8% decrease in sales were the 9% appreciation of the Japanese yen against the U.S. dollar.

Operating income of small precision motors decreased approximately ¥12,100 million, or 25%, to ¥36,344 million for this nine-month period compared to the previous nine-month period. This was mainly due to the appreciation of the Japanese yen against the U.S. dollar and the adverse effects of the flooding in Thailand. The appreciation of the Japanese yen against the U.S. dollar had a negative impact on operating income of small precision motors of approximately ¥6,500 million for this nine-month period.

General motors-

Net sales of general motors increased approximately ¥42,900 million, or 47%, to ¥134,103 million for this nine-month period compared to the previous nine-month period. Sales of general motors for home appliances and industrial use for this nine-month period increased approximately ¥34,400 million, or 57%, compared to the previous nine-month period, mainly reflecting an increase in sales relating to Nidec Motor Corporation, which we acquired in the second quarter of the prior year, of approximately ¥34,600 million for this nine-month period compared to the previous nine-month period. Sales relating to Nidec Techno Motor Corporation decreased for this nine-month period compared to the previous nine-month period due mainly to inventory adjustments-related effects in the European and Asian markets and the negative effects of the flooding in Thailand. Sales of general motors for automobiles increased approximately ¥8,500 million, or 28%, for this nine-month period compared to the previous nine-month period. Within the “general motors for automobiles” product category, sales of general motors for electric power steering by Nidec Corporation and its direct-line subsidiaries increased approximately 75% for this nine-month period compared to the previous nine-month period.

Operating income of general motors increased approximately ¥2,500 million, or 131%, to ¥4,414 million for this nine-month period compared to the previous nine-month period. Operating income of general motors for home appliances and industrial use increased for this nine-month period compared to the previous nine-month period mainly due to the contribution of Nidec Motor, more than offsetting the negative effect of Nidec Techno Motor's sales decrease. Operating income of general motors for automobiles increased for this nine-month period compared to the previous nine-month period, despite Nidec Corporation's increased investment cost relating to general motors for automobiles, including motors for electric power steering for automobiles, as we expect the market for this product category to grow and aim to strengthen our position in the market.

9

Machinery-

Net sales of machinery decreased approximately ¥7,900 million, or 14%, to ¥50,139 million for this nine-month period compared to the previous nine-month period. The decrease in net sales was mainly due to a decrease in sales of such products as LCD panel handling robots at Nidec Sankyo of approximately ¥4,400 million, or 17%, a decrease in sales of such products as electronic circuit testing systems for digital equipment at Nidec-Read of approximately ¥2,500 million, or 26%, a decrease in sales at Nidec-Kyori of approximately ¥900 million, or 15%, and a decrease in sales at Nidec Tosok of approximately ¥600 million, or 19%, for this nine-month period compared to the previous nine-month period. The decrease in net sales was partially offset by an increase in sales of such products as peripheral equipment for chip mounters at Nidec Copal of approximately ¥600 million, or 16%, for this nine-month period compared to the previous nine-month period.

Operating income of machinery decreased approximately ¥3,300 million, or 35%, to ¥6,239 million for this nine-month period compared to the previous nine-month period.

Electronic and optical components-

Net sales of electronic and optical components decreased approximately ¥14,600 million, or 16%, to ¥75,548 million for this nine-month period compared to the previous nine-month period. The decrease was mainly due to a decrease in sales of such products as shutters and unit components at Nidec Copal of approximately ¥9,100 million, or 21%, primarily as a result of the disruptions to our manufacturing facilities and supply chain caused by the flooding in Thailand, a decrease in sales of such products as control device units for home appliances at Nidec Sankyo of approximately ¥5,100 million, or 20%, mainly because of the disruptions to the supply chains caused by the flooding in Thailand, and a decrease in sales of electronic components, including circuit components and sensors, at Nidec Copal Electronics of approximately ¥400 million, or 2%, for this nine-month period compared to the previous nine-month period.

Operating income of electronic and optical components decreased approximately ¥7,100 million, or 52%, to ¥6,632 million for this nine-month period compared to the previous nine-month period. This decrease was primarily due to the decrease in sales, the appreciation of the Japanese yen against the U.S. dollar, and higher raw material prices.

Other products-

Net sales of other products increased approximately ¥2,300 million, or 9%, to ¥28,367 million for this nine-month period compared to the previous nine-month period. This was primarily due to an increase in sales of automotive parts at Nidec Tosok of approximately ¥2,800 million, or 15%, for this nine-month period compared to the previous nine-month period, resulting from increasing demand for such parts in China and Europe with orders for such parts from customers who were affected by the supply chain disruptions caused by the earthquake in northern Japan in March 2011 also improving. The increase in net sales of other products were partially offset by a decrease in sales of pivot assemblies for HDDs of approximately ¥1,100 million, or 66%, for this nine-month period compared to the previous nine-month period.

Operating income of other products decreased approximately ¥700 million, or 19%, to ¥3,100 million for this nine-month period compared to the previous nine-month period. This was mainly due to excess fixed costs resulting from a temporary decrease in demand due to disruptions in supply chains caused by the earthquake, which adversely affected Nidec Tosok's customers for the three months ended June 30, 2011, and the decrease in sales of pivot assemblies for HDDs.

10

Consolidated Operating Results for the Three Months Ended December 31, 2011 ("this 3Q") Compared to the Three Months Ended September 30, 2011 ("this 2Q")

Consolidated net sales decreased ¥24,643 million, or 13.5%, to ¥157,982 million for this 3Q compared to this 2Q. Our operating income decreased ¥7,175 million, or 35.3%, to ¥13,147 million for this 3Q compared to this 2Q Operating income ratio was 8.3% for this 3Q. This decrease was mainly due to the negative effects of the flooding in Thailand on our "small precision motors," "general motors" and "electronic and optical components" product categories. However, we estimated as of December 31, 2011, that insurance payments to be received under the property damage insurance policies we hold would exceed the loss relating to the fixed assets and inventories, and the amount of the insurance payments estimated as of December 31, 2011, exceeding the loss was recorded as part of operating income presented in our consolidated income statements for the three months ended December 31, 2011. The average exchange rate between the Japanese yen and the U.S. dollar for this 3Q was ¥77.41 to the dollar, an appreciation of the Japanese yen against the U.S. dollar of approximately ¥0.48 compared to this 2Q. The average exchange rate between the Japanese yen and the Euro for this 3Q was ¥104.33 to the Euro, an appreciation of the Japanese yen against the Euro of approximately ¥5.86, or 5%, compared to this 2Q. The appreciation of the Japanese yen against the U.S. dollars and Euro had a negative impact on our net sales and operating income of approximately ¥1,600 million and ¥400 million, respectively, for this 3Q compared to this 2Q.

Income from continuing operations before income taxes decreased ¥1,821 million, or 11.6%, to ¥13,831 million for this 3Q compared to this 2Q. We recorded foreign exchange gains of approximately ¥900 million for this 3Q, compared to a foreign exchange loss of approximately ¥4,000 million for this 2Q. Net income attributable to Nidec Corporation also decreased ¥1,194 million, or 11.6%, to ¥9,125 million for this 3Q compared to this 2Q.

Total assets increased approximately ¥1,400 million to ¥749,639 million as of December 31, 2011, compared to March 31, 2011. This increase was primarily due to an increase of approximately ¥18,400 million in other current assets due mainly to accrued insurance receivable for the physical damage to fixed-assets and inventories caused by the flooding in Thailand, and an approximately ¥11,300 million increase in cash and cash equivalents, offset in part by a decrease in property, plant and equipment of approximately ¥22,700 million primarily due to the flooding in Thailand.

Total liabilities increased approximately ¥15,100 million to ¥352,773 million as of December 31, 2011, compared to March 31, 2011. Our short-term borrowings increased approximately ¥32,500 million to approximately ¥84,500 million as of December 31, 2011, compared to March 31, 2011. Our debt ratio increased to 24.9% as of December 31, 2011 from 20.7% as of March 31, 2011. Our debt to equity ratio was 0.54 as of December 31, 2011, compared to 0.44 as of March 31, 2011. Our net debt to equity ratio was 0.24 as of December 31, 2011, compared to 0.17 as of March 31, 2011.

Nidec Corporation shareholders’ equity decreased approximately ¥12,600 million to ¥342,696 million as of December 31, 2011 compared to March 31, 2011, primarily due to an increase in accumulated other comprehensive loss of approximately ¥21,500 million, which reflected an increase in negative foreign currency translation adjustments of approximately ¥20,000 million resulting from the appreciation of the Japanese yen against the U.S. dollar. The decrease in Nidec Corporation shareholders’ equity was partially offset by an increase in retained earnings of approximately ¥19,300 million and repurchases of treasury stock (representing approximately 1% of our shares issued and outstanding) for approximately ¥10,200 million.

13

Nidec Corporation shareholders' equity to total assets decreased to 45.7% as of December 31, 2011 from 47.5% as of March 31, 2011.

In connection with our acquisition of Nidec Seimitsu in this 2Q, as of December 31, 2011, we recorded approximately ¥11,600 million in total assets, including approximately ¥3,300 million in trade accounts receivable, and approximately ¥4,100 million in total liabilities, including approximately ¥2,600 million in trade notes and accounts payable.

Overview of Cash Flow-

(in millions)	For the nine months ended December 31, 2011	For the nine months ended December 30, 2010	Inc/dec
Net cash provided by operating activities	¥42,149	¥56,126	(¥13,977)
Net cash used in investing activities	(24,300)	(94,195)	69,895
Free cash flow *1	17,849	(38,069)	55,918
Net cash provided by financing activities	13	14,350	(14,337)

Note: *1: To supplement our statements of cash flows presented on a GAAP basis, we use non-GAAP measures of cash flows to analyze cash flows generated from our operations. The presentation of non-GAAP free cash flow is not meant to be considered in isolation or as an alternative to net income as an indicator of our performance, or as an alternative to cash flows from operating activities as a measure of liquidity. Our free cash flow is the sum of “net cash flow from operating activities” and “net cash flow from investing activities.”

Cash flow from operating activities for the nine months ended December 31, 2011 ("this nine-month period") was a net inflow of ¥42,149 million. Compared to the nine months ended December 31, 2010 ("the previous nine-month period"), our cash inflow from operating activities for this nine-month period decreased approximately ¥14,000 million. This decrease was mainly due to a decrease in consolidated net income of approximately ¥11,100 million and the negative effects of a decrease in trade notes and accounts payable of approximately ¥14,500 million, which were offset in part by a smaller decrease in inventories by approximately ¥12,900 million, compared to the previous nine-month period.

Cash flow from investing activities for this nine-month period was a net cash outflow of ¥24,300 million. Compared to the previous nine-month period, our net cash outflow decreased approximately ¥69,900 million mainly due to acquisitions of business, net of cash acquired, of approximately ¥52,000 million for the previous nine-month period and a decrease in additional purchases of property, plant and equipment of approximately ¥14,200 million for this nine-month period compared to the previous nine-month period.

As a result, we had a positive free cash flow of ¥17,849 million for this nine-month period, compared to a negative free cash flow of ¥38,069 million for the previous nine-month period.

Cash flow from financing activities decreased approximately ¥14,300 million to ¥13 million for this nine-month period compared to the previous nine-month period. We had an increase in short-term borrowings of approximately ¥84,300 million for this nine-month period compared to the previous nine-month period, mainly due to a new issuance of commercial paper for this nine-month period. However, we had no cash inflow from proceeds from issuance of corporate bonds for this nine-month period, compared to approximately ¥100,500 million for the previous nine-month period.

14

As a result of the foregoing and the impact of foreign exchange fluctuations, the balance of cash and cash equivalents as of December 31, 2011 was ¥105,606 million, an increase of ¥11,285 million from March 31, 2011.

(3) Business Forecasts for the Fiscal Year ending March 31, 2012

The global economy weakened due to the financial crisis in Europe and its ramifications that had further deteriorating effects, and supply chains for various industries were disrupted by the flooding in Thailand, causing our subsidiaries in Thailand to temporarily suspend operations. As a result of the large-scale supply chain disruptions and other factors, we currently expect lower sales and income. In addition, in light of the continuing appreciation of the Japanese yen against other currencies, we have revised our assumed average exchange rates applicable to the three months ending March 31, 2012, from €1 = ¥105 to €1 = ¥95.

Considering the foregoing, we have revised downward our previously announced financial performance forecasts for the fiscal year ending March 31, 2012, as follows. We have kept our previously announced forecast of full-year dividends of ¥90 per share.

Forecasts of consolidated results for the fiscal year ending March 31, 2012

Net sales	¥700,000 million	(Up 1.7% from the previous fiscal year)
Operating income	¥70,000 million	(Down 22.7% from the previous fiscal year)
Income from continuing operations before income taxes	¥62,000 million	(Down 22.0% from the previous fiscal year)
Net income attributable to Nidec Corporation	¥40,000 million	(Down 23.6% from the previous fiscal year)

Note:

The exchange rates used for the preparation of the foregoing forecasts are U.S.$1 = ¥75 and €1 = ¥95. The exchange rates between the relevant Asian currencies and the Japanese yen used for the preparation of the foregoing forecasts were determined assuming this U.S. dollar-Japanese yen exchange rate and the Euro-Japanese yen exchange rate.

2. Others

(1) Change in significant subsidiaries during this period (due to changes in the scope of consolidation)

None.

(2) Adoption of simplified accounting methods and accounting methods used specifically for quarterly consolidated financial statements

   (Accounting method relating to corporate income tax and other taxes)

Corporate income tax and other taxes are calculated for the quarterly reporting period based on an estimated annual tax rate which is based on the legal income tax rate.

(3) Changes in accounting method in this period

As of April 1, 2011, NIDEC adopted FASB Accounting Standards Codification™ (ASC) 350 “Intangibles - Goodwill and Other” updated by Accounting Standards Update (ASU) No. 2010-28 “When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts.” ASU 2010-28 modifies Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. The adoption of this standard did not have a material impact on NIDEC’s consolidated financial position, results of operations or liquidity.

15

As of April 1, 2011, NIDEC adopted FASB ASC 805 “Business Combinations” updated by ASU No. 2010-29 “Disclosure of Supplementary Pro Forma Information for Business Combinations.” ASU 2010-29 requires a public entity that enters into business combination to disclose pro forma revenue and earnings of the combined entity in the comparative financial statements as though the business combination(s) that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. ASU 2010-29 also expands the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings. ASU2010-29 is a provision for disclosure. The adoption of ASU2010-29 did not have any impact on NIDEC’s consolidated financial position, results of operations and liquidity.

Notes:

1. Pursuant to ASC 205-20 “Presentation of Financial Statements-Discontinued Operations”, results of discontinued operations were separated as “Loss from discontinued operations” from results of continuing operations. The results of the discontinued operations for the nine months ended December 31, 2010 and for the fiscal year ended March 31, 2011 have been reclassified. Therefore, “Information by Product Category”, “Sales by Geographic Segment” and “Sales by Region” in this report have also been retrospectively reclassified.

2. Pursuant to ASC 805 "Business Combinations", the results of operations for the nine months ended December 31, 2010 have been adjusted retrospectively, as a fair value evaluation of the assets acquired and the liabilities assumed at the point of the acquisition of Nidec Motor Corporation completed in the three months ended March 31, 2011.
