Nidec Revises Consolidated Financial Forecasts

for the Year Ending March 31, 2013 Downward

Nidec Corporation (NYSE: NJ) today announced a downward revision on its consolidated financial forecasts (announced on April 24, 2012) for the year ending March 31, 2013 as follows.

1. Revised consolidated financial forecasts (U.S. GAAP) for the year ending March 31, 2013

From April 1, 2012 to March 31, 2013 (Millions of yen, except per share amounts and percentages)
	For the year ending March 31, 2013				For the year ended            March 31, 2012
	Previous forecast (April 24, 2012)	Revised Forecast	Change (amount)	Change (percent)
Net sales	780,000	720,000	(60,000)	(7.7 %)	682,320
Operating income	95,000	80,000	(15,000)	(15.8%)	73,070
Income from continuing operations before income taxes	87,000	71,000	(16,000)	(18.4 %)	70,856
Net income attributable to Nidec Corporation	57,000	50,000	(7,000)	(12.3 %)	40,731
Net income attributable to Nidec Corporation per share-basic	423.63	370.45	-	-	296.25

2. Reasons for the revision

As the economic deterioration in Europe continues to have an adverse effect on the global economy, including China and other emerging economies, the demand for our products is expected to decrease further. In light of this trend and other factors, we have reviewed our previously announced financial performance forecasts, which were based on our assumption that the trend would reverse and the demand would increase in the six months ending March 31, 2013, and have determined to revise downward our previously announced financial performance forecasts for the fiscal year ending March 31, 2013.

However, we have not revised our dividend target for the fiscal year ending March 31, 2013, which remains at ¥95 per share.

Notes:

(1) The exchange rates used for the preparation of the foregoing forecasts are US$1=¥78 and €1=¥95. The exchange rates between the relevant Asian currencies and the Japanese yen used for the preparation of the foregoing forecasts have been determined assuming these U.S. dollar-Japanese yen and the Euro-Japanese yen exchange rates.

(2) “Net income attributable to Nidec Corporation per share—basic” reflects the share exchange transaction between Nidec Corporation and Nidec Sankyo Corporation on October 1, 2012 to make Nidec Sankyo a wholly owned subsidiary, in which transaction 3,175,315 shares in the aggregate of treasury stock of Nidec Corporation were allocated to Nidec Sankyo shareholders.
