CAREFUSION REPORTS FOURTH QUARTER AND FISCAL 2010 RESULTS,

ANNOUNCES COMPANY-WIDE RESTRUCTURING

SAN DIEGO, Aug. 10, 2010 – CareFusion Corp. (NYSE: CFN), a leading, global medical device company, today reported results from continuing operations for the three months and fiscal year ended June 30, 2010 and announced a company-wide restructuring expected to generate more than $100 million in annual savings when fully implemented.

“The results we reported today reflect solid performances across our business segments in our first year as a public company. We overachieved against our original fiscal 2010 expectations with incremental positive contributions from both our Infusion and Respiratory businesses,” said David Schlotterbeck, chairman and CEO of CareFusion. “During fiscal 2010, we evaluated our cost structure and the strategic fit of certain businesses and are now taking the necessary steps to right size our company. Our goal is to improve our competitive position, accelerate our previously announced efforts to improve our operating margins and enhance our focus on the core opportunities we have for growth.”

“Our guidance for fiscal 2011 is consistent with the long-term goals for top- and bottom-line growth we have previously provided. We are expecting revenue growth of mid single digits on a reported basis over fiscal 2010 results, and adjusted diluted earnings per share of $1.58 to $1.68, an 11 to 18 percent increase. Our fiscal 2011 growth projections include overcoming the Infusion and Respiratory benefits in 2010, as well as the impact in the change in currency from 2010 to 2011, all of which total approximately $210 million. Taking into account these items, our underlying core revenue growth rate is 10 to 12 percent for next year.”

Restructuring

CareFusion announced today that it initiated a company-wide restructuring that is expected to reduce the company’s global workforce by approximately 700 positions. The reductions are designed to eliminate layers of management and reduce the size of the company’s supporting infrastructure.

In connection with the restructuring, CareFusion estimates it will generate pre-tax cost savings in fiscal 2011 of $85 million to $95 million and for that amount to increase by an additional $25 million in fiscal 2012. In addition, the company estimates incurring total pre-tax, nonrecurring expenses of approximately $40 million to $50 million in fiscal 2011 related to this restructuring, which includes employee separation and other costs.

Fourth Quarter Results

CareFusion’s reported results compare to the three month and fiscal year periods ended June 30, 2009.

Revenue in the fourth quarter increased 19 percent to $1 billion on both a reported and constant currency basis, driven primarily by increased sales in the company’s Infusion, Respiratory and Medical Technologies and Services businesses. Operating income increased to $135 million from $85 million. Excluding nonrecurring items, adjusted operating income for the fourth quarter increased 44 percent to $147 million.

Operating expenses, including selling, general and administrative (SG&A), research and development (R&D) and restructuring and acquisition integration charges in the fourth quarter totaled $362 million, or 35 percent of total revenue. Excluding nonrecurring items, adjusted operating expenses in the fourth quarter totaled $338 million, or 33 percent of total revenue. Adjusted SG&A expenses were $294 million and R&D investments totaled $44 million.

The company reported income from continuing operations in the fourth quarter of $52 million, or $0.23 per diluted share. Adjusted net income was $85 million, or $0.38 per diluted share, and the adjusted tax rate was 33.2 percent for the fourth quarter.

Fiscal 2010 Results

For fiscal 2010, revenue increased 9 percent to $3.9 billion on both a reported and constant currency basis, driven primarily by increased sales in the company’s Infusion, Respiratory and Medical Technologies and Services businesses, which were partially offset by a decrease in the company’s Dispensing business. Operating income increased $28 million to $472 million. Excluding nonrecurring items, adjusted operating income for fiscal 2010 increased to $542 million from $516 million.

Operating expenses, including SG&A, R&D and restructuring and acquisition integration charges in fiscal 2010 totaled $1.4 billion, or 36 percent of total revenue. Excluding nonrecurring items, adjusted operating expenses for fiscal 2010 totaled $1.3 billion, or 34 percent of total revenue. Adjusted SG&A expenses were $1.2 billion, and R&D investments totaled $159 million.

The company reported income from continuing operations for fiscal 2010 of $171 million, or $0.77 per diluted share. Adjusted net income increased $1 million to $317 million, or $1.42 per diluted share, and the adjusted tax rate was 29.5 percent for fiscal 2010.

Use of Non-GAAP Financial Measures by CareFusion Corporation

This CareFusion news release presents the non-GAAP financial measures “adjusted operating expenses”, “adjusted SG&A expenses”, “adjusted operating income”, “adjusted net income”, “adjusted diluted earnings per share” and “adjusted segment profit”. The most directly comparable measure for these non-GAAP financial measures are operating expenses, SG&A expenses, operating income, net income, diluted earnings per share and segment profit. The company has included below unaudited adjusted financial information for the quarters and fiscal years ended June 30, 2010 and 2009, which present the company’s results of operations after excluding restructuring and acquisition integration charges, nonrecurring spinoff related costs, nonrecurring gain on the sale of assets, nonrecurring tax items and discontinued operations.

In addition, CareFusion presents the non-GAAP financial measure “adjusted diluted earnings per share” on a forward-looking basis. The most directly comparable forward-looking GAAP measure for the company is diluted earnings per share. CareFusion is unable to provide a quantitative reconciliation of this forward-looking non-GAAP financial measure to the most directly comparable forward-looking GAAP measure, because the company cannot reliably forecast restructuring and acquisition integration costs, and other nonrecurring costs. Please note that the unavailable reconciling items could significantly impact CareFusion’s future financial results. A discussion of the reasons why management believes that the presentation of non-GAAP financial measures provides useful information to investors regarding CareFusion’s financial condition and results of operations is included as Exhibit 99.3 to CareFusion’s report on Form 8-K filed with the Securities and Exchange Commission on Aug. 10, 2010.
