CAREFUSION REPORTS SECOND QUARTER FISCAL 2011 RESULTS

SAN DIEGO, Feb. 3, 2011 – CareFusion Corp. (NYSE: CFN), a leading, global medical technology company, today reported results for the three and six months ended Dec. 31, 2010.

“Our strong second quarter results were driven by increased sales in our Infusion, Dispensing and Infection Prevention businesses, and a benefit from a lower tax rate,” said David Schlotterbeck, CareFusion’s outgoing chairman and CEO, who had announced in November 2010 his plans to retire. On Feb. 1, the company announced Kieran T. Gallahue as Schlotterbeck’s successor. “We exceeded our internal earnings expectations for the first half of fiscal 2011, and overcame prior year period benefits from sales related to H1N1 and our Alaris^® System ship hold release. Committed contracts booked during the quarter were at or near record levels in the Infusion and Dispensing businesses, giving us positive momentum into the second half of fiscal 2011 and even into fiscal 2012.

“We are updating our fiscal 2011 financial outlook to reflect the revenue and EPS impact of the divesture of our International Surgical Products (ISP) and OnSite Services businesses, as well as a reduction in our Infusion revenue estimates as the expected timing of pump conversions shifts sales from fiscal 2011 to fiscal 2012.

“For fiscal 2011, we are now expecting adjusted diluted EPS in the range of $1.58 to $1.65, which includes absorbing approximately $0.07 dilution from the divestitures of ISP and OnSite, and lowering our revenue growth guidance from mid single digits to low single digits growth.”

Agreement to Divest of International Surgical Products Business

CareFusion announced today that it has signed an agreement to sell its ISP business to Medline Industries, Inc. For the full fiscal year 2011, revenues and earnings per share associated with the ISP business are estimated to be $440 million and $0.06, respectively. The results of the ISP operations have not been classified as discontinued operations in the accompanying financial tables as the criteria for this classification was not met in the second quarter of fiscal 2011. The divestiture is

expected to close in April 2011, subject to customary closing conditions. The company will include the ISP results in discontinued operations beginning in the third quarter of fiscal 2011.

Second Quarter Results

CareFusion’s reported results compare to the three and six month periods ended Dec. 31, 2009.

The company reported revenue for the second quarter of fiscal 2011 of $1,002 million, compared to $1,019 million in the second quarter of fiscal 2010, a decrease of 2 percent on a reported basis or 1 percent on a constant currency basis after adjusting for an $8 million unfavorable foreign currency impact. The year-over-year decline was driven primarily by lower sales in the company’s Respiratory business.

Operating income was $126 million, down 1 percent compared to $127 million in the prior year period. Excluding nonrecurring items, adjusted operating income for the second quarter increased to $155 million from $149 million.

Operating expenses, including selling, general and administrative (SG&A), research and development (R&D) and restructuring and acquisition integration charges in the second quarter totaled $349 million, or 35 percent of total revenue. Excluding nonrecurring items, adjusted operating expenses in the second quarter totaled $320 million, or 32 percent of total revenue. Adjusted SG&A expenses were $284 million and R&D investments totaled $36 million.

The company reported income from continuing operations in the second quarter of $76 million, or $0.34 per diluted share. Adjusted income from continuing operations was $98 million, or $0.44 per diluted share, and the adjusted tax rate was 26.8 percent for the second quarter.

Critical Care Technologies

Second quarter revenue for the Critical Care Technologies segment totaled $684 million, and was flat on a reported basis and increased 1 percent on a constant currency basis compared to the prior year period. Segment revenues in the quarter were driven by an increase in the company’s Infusion product sales, which included core Infusion growth and a contribution from the company’s May 2010 acquisition of Medegen, and an increase in the company’s Dispensing business, which benefited from competitive displacements. The increase in Infusion and Dispensing sales was offset by an expected decrease in the company’s Respiratory product line revenues. Respiratory sales continued to be negatively impacted by a weak post H1N1 environment, declines in hospital admissions and a lighter flu season than in the prior year period.

Segment profit decreased 1 percent to $110 million. Adjusted segment profit increased 2 percent to $128 million, primarily due to strong Infusion and Dispensing results.

Medical Technologies and Services

Second quarter revenue for the Medical Technologies and Services segment decreased 6 percent to $318 million, or 4 percent on a constant currency basis, compared to the prior year period. Segment revenues in the quarter were driven by decreased sales in the company’s ISP business, the loss of revenue from the company’s Research Services business that was divested in May 2010 and by foreign currency rates during the current year quarter. Partially offsetting this decline was increased sales from the company’s Infection Prevention business.

Excluding the revenues associated with the company’s ISP, OnSite Services and Research Services businesses, all of which are included in the Medical Technologies and Services segment, segment revenues grew 5 percent in the second quarter compared to the prior year period.

Segment profit was unchanged at $16 million. Adjusted segment profit increased 17 percent to $27 million, based on growth in the company’s Infection Prevention business, which offset the year-over-year decline in currency and the loss of income from the Research Services divestiture.

Six-Month Results

For the first six months of fiscal 2011, revenue decreased 2 percent to $1,910 million. Operating income declined to $208 million from $244 million. Income from continuing operations was $114 million, or $0.51 per diluted share.

Excluding nonrecurring items, adjusted operating income for the first six months of fiscal 2011 decreased to $277 million from $283 million and adjusted income from continuing operations decreased $9 million to $165 million, or $0.73 on an adjusted basis per diluted share.

Operating expenses, including SG&A, R&D, and restructuring and acquisition integration charges in the first six months of fiscal 2011 totaled $707 million or 37 percent of total revenue. Excluding $69 million of nonrecurring items, adjusted operating expenses in the first six months of fiscal 2011 totaled $638 million, or 33 percent of total revenue. Adjusted SG&A expenses were $562 million, and R&D investments totaled $76 million.

Segment results for the six months ended Dec. 31, 2010 and 2009 are as follows:

Adjusted operating expenses, adjusted SG&A expenses, adjusted operating income, adjusted income from continuing operations, adjusted diluted earnings per share and adjusted segment profit are non-GAAP financial measures and exclude restructuring and acquisition integration charges, nonrecurring related costs, nonrecurring tax items and discontinued operations. Adjusted income from continuing operations also excludes nonrecurring costs related to the bridge loan entered into in connection with the spinoff. A reconciliation of GAAP to non-GAAP financial measures is included later in this news release.

Fiscal 2011 Outlook

CareFusion’s updated financial outlook for full-year fiscal 2011 reflects the anticipated impact of the divesture of the ISP business announced today and the previously announced divestiture of our OnSite Services business, both of which are expected to close in the fourth quarter of fiscal 2011. Our outlook also reflects revised expectations regarding the timing of Infusion revenues and our tax rate, as discussed below. Taking into account these factors, the company now expects adjusted diluted earnings per share for fiscal 2011 to be in the range of $1.58 to $1.65, instead of the previously

provided range of $1.58 to $1.68. If the divestitures of ISP and OnSite had occurred in fiscal 2010, our fiscal 2010 adjusted diluted earnings per share would have been approximately $1.33 and revenues would have been $3.5 billion. The company is also lowering its revenue guidance growth targets. The company’s previously issued guidance anticipated mid single digit growth over fiscal 2010 reported revenues of $3.9 billion. The company’s updated guidance anticipates low single digit growth over $3.5 billion.

The company anticipates the impact of the ISP and OnSite divestitures will reduce fiscal 2011 revenues and adjusted diluted earnings per share by approximately $450 million and $0.07, respectively. The updated financial outlook for full-year fiscal 2011 also reflects a reduction in the company’s Infusion revenue estimates due to a shift in sales from fiscal 2011 to fiscal 2012 to account for an extended time period for pump conversions. In addition, the company is lowering its adjusted tax rate guidance to a range of 28 to 30 percent, down from 30 to 32 percent previously provided.

The guidance is based on an assumed diluted weighted average outstanding share count of approximately 225 million.

quarter and six month periods ended Dec. 31, 2010 and 2009, which present the company’s results of operations after excluding restructuring and acquisition integration charges, nonrecurring related costs, 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 Feb. 3, 2011.
