Exhibit 99

Eaton First Quarter Operating Earnings Per Share of $0.84 Exceed Midpoint of Guidance by 12 Percent

Cooper Industries Integration on Track

2013 Earnings Guidance Affirmed

DUBLIN, Ireland … Diversified industrial manufacturer Eaton Corporation plc (NYSE:ETN) today announced record quarterly sales and operating profits, driven by the acquisition of Cooper Industries. Sales in the first quarter of 2013 were $5.31 billion, 34 percent above the same period in 2012. Operating earnings for the first quarter of 2013, excluding charges of $22 million to integrate recent acquisitions, were a record $400 million, an increase of 28 percent over 2012. Operating earnings per share, which exclude charges of $0.05 per share to integrate recent acquisitions, were $0.84 for the first quarter of 2013. This result is a decrease of 9 percent from the first quarter of 2012, reflecting the shares issued as part of the acquisition of Cooper Industries and the purchase price accounting charges resulting from the transaction.

Alexander M. Cutler, Eaton chairman and chief executive officer, said, “Our first quarter results are a solid start to the year, coming in above the high end of our guidance despite markets being slightly weaker than our expectations. We were able to generate attractive operating margins, reflecting our enhanced portfolio as a result of the Cooper Industries acquisition and our continued focus on productivity improvements.

“Our 34 percent sales growth in the first quarter consisted of a decline of 5 percent in core sales and a 1 percent decline from currency translation, offset by 40 percent growth from acquisitions,” said Cutler. “Our markets in the first quarter were lower than a year ago, reflecting a continuation of the sluggish economic conditions experienced in many parts of the world during the second half of 2012.

“We entered 2013 expecting it would be a year of subpar global economic growth, leading to approximately 2 to 3 percent growth in our markets,” said Cutler. “We continue to believe our markets will grow 2 to 3 percent in 2013, most likely toward the lower end of the range.

“We anticipate operating earnings per share for the second quarter of 2013, which exclude an estimated $25 million of charges to integrate our recent acquisitions, to be between $1.05 and $1.15,” said Cutler. “There are two primary drivers of the expected increase in second quarter operating earnings per share over the first quarter: first, seasonally higher volumes, since our sales in the second quarter are typically 5 to 10 percent higher, and second, the absence of purchase price inventory expense in the second quarter related to the Cooper Industries acquisition.

“We are maintaining our guidance for full year operating earnings per share of between $4.05 and $4.45,” said Cutler. “2013 is a year in which our results will depend more on our execution than on global growth. We are off to a great start this year, with our execution driving stronger than expected results in the first quarter. Based on the midpoint of our guidance, our operating earnings per share in 2013 will grow 8 percent.”

Business Segment Results

Sales for the Electrical Products segment were $1.7 billion, up 87 percent over 2012, reflecting the impact of the Cooper Industries acquisition. Operating profits were $241 million. Excluding acquisition integration charges of $3 million during the quarter, operating profits were $244 million, up 76 percent over the first quarter of 2012.

“Our bookings in the Electrical Products segment were down 3 percent from the combined bookings of Eaton and legacy Cooper in the first quarter a year ago,” said Cutler.

Sales for the Electrical Systems and Services segment were $1.5 billion, up 79 percent over the first quarter of 2012, reflecting the impact of the Cooper Industries acquisition. The segment reported operating profits of $210 million. Excluding acquisition integration charges of $5 million during the quarter, operating profits were $215 million, up 176 percent. Combined bookings in the quarter increased 2 percent compared to the first quarter of 2012.

“In both of our Electrical segments, our end markets were strongest in the U.S., the Middle East and Latin America, with mixed conditions in Asia Pacific and weakness in Europe,” said Cutler. “We believe sales will improve during the balance of the year, in line with the normal seasonal pattern of demand.”

Hydraulics segment sales were $756 million, an increase of 3 percent compared to the first quarter of 2012. Sales growth was driven by revenues from acquisitions completed in 2012, which accounted for 13 percent growth, offset by a 9 percent decline in core sales and a 1 percent decline from currency translation. Operating profits in the first quarter were $78 million. Excluding acquisition integration charges of $12 million, operating profits were $90 million, a decline of 18 percent.

“The hydraulics markets in the first quarter grew modestly compared to the fourth quarter,” said Cutler. “Compared to strong conditions in the first quarter of 2012, the year-over-year comparisons are negative. Reflecting this, our bookings in the quarter declined 8 percent from the first quarter of 2012.”

Aerospace segment sales were $434 million, up 1 percent over the first quarter of 2012. Operating profits in the first quarter were $62 million, an increase of 3 percent compared to a year earlier.

“Aerospace markets grew modestly in the first quarter, with strongest growth in the commercial OEM market,” said Cutler.

The Vehicle segment posted sales of $939 million, down 11 percent compared to the first quarter of 2012. The segment reported operating profits in the first quarter of $132 million, a decrease of 18 percent from the first quarter of 2012.

“Continuing the trends we saw in the second half of last year, our NAFTA and European customers experienced generally weaker market conditions,” said Cutler.

NOTES TO THE FIRST QUARTER 2013 EARNINGS RELEASE

Amounts are in millions of dollars unless indicated otherwise (per share data assume dilution).

This earnings release includes certain non-GAAP financial measures. These financial measures include operating earnings, operating earnings per ordinary share, and operating profit before acquisition integration charges and transaction costs for each business segment as well as corporate expense, each of which excludes amounts that differ from the most directly comparable measure calculated in accordance with generally accepted accounting principles (GAAP). A reconciliation of each of these financial measures to the most directly comparable GAAP measure is included in this earnings release. Management believes that these financial measures are useful to investors because they exclude transactions of an unusual nature, allowing investors to more easily compare Eaton's financial performance period to period. Management uses this information in monitoring and evaluating the on-going performance of Eaton and each business segment.

The effective income tax rate for the first quarter of 2013 was 5.0% compared to 15.6% for the first quarter of 2012. The lower effective tax rate in the first quarter of 2013 was primarily attributable to recording in the first quarter of 2013 the entire U.S. research and experimentation credit for 2012 as a result of a legislative change that occurred in January 2013, the effects of the Cooper transaction and integration, and enhanced utilization of foreign tax credits in the U.S.
