Exhibit 99

- Company increases full-year guidance; now expects to earn 14% EBIT on $17 billion in sales

COLUMBUS, IN – Cummins Inc. (NYSE: CMI) today reported sharply higher sales and earnings compared to the first quarter of 2010 on continued strength in key international markets, a recovering North American truck market and productivity improvements.

First quarter sales of $3.9 billion were up 56 percent from $2.5 billion in the same period in 2010. Earnings before interest and taxes (EBIT) were $532 million or 13.8 percent of sales, double the Company’s earnings from the same period a year ago. EBIT as a percentage of sales in the first quarter was at its highest level in at least 25 years.

Net income attributable to Cummins Inc. was $343 million ($1.75 per share) compared to $149 million (75 cents per share) in the first quarter of 2010.

“Our outstanding first quarter results demonstrate that we are well positioned to take advantage of our significant growth opportunities as markets around the world continue to recover,” said Tim Solso, Chairman and Chief Executive Officer. “The work we have done over the past two years to keep the Company strong during the global economic recession is paying off today.”

As a result of the Company’s performance in the first quarter and its forecast for the remainder of the year, Cummins today increased both its EBIT and sales guidance for 2011. The Company now expects to earn 14 percent EBIT on $17 billion in sales in 2011.

Engine segment sales of $2.4 billion were up 68 percent compared to the same quarter a year ago, which was artificially weak due to a change in emissions standards and the economic downturn. Segment EBIT of $290 million, or 12.1 percent of sales, was a quarterly record.

Engine shipments in the global heavy-duty truck market more than tripled year-over-year, while medium-duty truck engine shipments increased 114 percent. In addition, shipments to global industrial markets such as construction (up 60 percent) and mining (up 59 percent) also were strong.

Sales in the Components segment, propelled by recovery in Europe, growth in China and India, and higher content of emission controls products on engines in North America, were up 47 percent to a record $924 million. Segment EBIT of $105 million, or 11.4 percent, also was a quarterly record for the Components group.

Power Generation sales increased 54 percent to $795 million on the strength of improved sales in its commercial products. Total segment sales in Western Europe increased 88 percent; 81 percent in the Middle East and 47 percent in India. Segment EBIT was $89 million, or 11.2 percent of sales.

The Distribution segment saw a sales increase of 35 percent to $642 million due to growth in most major markets, especially Europe, North and Central America and Asia Pacific. Segment EBIT of $89 million, or 13.9 percent of sales, was a quarterly record.

The Company’s non- U.S. markets continued showing strong growth as sales were up in every major international region compared to the same period last year. Consolidated sales in China were up 66 percent; India 31 percent; Brazil 39 percent; Africa and Middle East 40 percent. Sales outside the United States accounted for 61 percent of the Company’s revenue in the quarter.

“Our first quarter results reflect strong growth in demand for our products across most of our markets,” said Cummins President and Chief Operating Officer Tom Linebarger. “We expect the growth to continue and are investing significantly in the additional capacity needed to serve our customers around the world.”

The Company’s guidance for 2011excludes any gains from the previously announced sale of two businesses, which are expected to close later in the year.

The Company continued to return value to shareholders by repurchasing $190 million worth of Company shares in the first quarter. Cummins also announced a new share repurchase program in February that authorizes the acquisition of up to $1 billion in stock.

(2)	Depreciation and amortization as shown on a segment basis excludes the amortization of debt discount that is included in the Condensed Consolidated Statements of Income as “interest expense.”

A reconciliation of our segment information to the corresponding amounts in the Condensed Consolidated Statements of Income is shown in the table below:

Unit shipments by engine classification (including unit shipments to Power Generation)

We define EBIT as earnings or loss before interest expense, income tax expense and noncontrolling interests in income of consolidated subsidiaries (EBIT). We use EBIT to assess and measure the performance of our operating segments and also as a component in measuring our variable compensation programs. Below is a reconciliation of EBIT, a non-GAAP financial measure, to “Net income attributable to Cummins Inc.,” for each of the applicable periods:

We believe this is a useful measure of our operating performance for the periods presented as it illustrates our operating performance without regard to financial methods, capital structure or income taxes. This measure is not in accordance with, or an alternative for, accounting principles generally accepted in the United States of America and may not be consistent with measures used by other companies. It should be considered supplemental data.

Equity, royalty and interest income from investees included in our Condensed Consolidated Statements of Income for the interim reporting periods was as follows:

Our effective tax rate for the year is expected to approximate 30 percent, absent any discrete period activity. Our tax rate is generally less than the 35 percent U.S. statutory income tax rate primarily due to lower tax rates on foreign income and research credits. The tax rate for the three month period ended March 27, 2011, was 30 percent.

Our effective tax rate for the comparable prior year period was 34 percent and included a discrete tax charge of $7 million (three percent) related to the enactment of the “Patient Protection and Affordable Care Act”. This rate was less than the 35 percent U.S. statutory income tax rate primarily due to lower tax rates on foreign income.
