Exhibit 99.3

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The preliminary unaudited pro forma condensed combined financial information and notes thereto set forth below give effect to the acquisition (the “CareFusion Acquisition”) of CareFusion Corporation (“CareFusion”) and related financing transactions (collectively, the “Transactions”) as if they had occurred as of the end of each period presented, with respect to the balance sheet, and as of October 1, 2013, for the statement of income. Certain financial information of CareFusion as presented in its consolidated financial statements has been reclassified to conform to the historical presentation of BD’s consolidated financial statements for purposes of preparation of the unaudited pro forma condensed combined financial information. The unaudited pro forma condensed combined financial information shows the impact of the CareFusion Acquisition on the combined balance sheet and the combined income statement under the acquisition method of accounting with BD treated as the acquirer. Under this method of accounting, identifiable tangible and intangible assets acquired and liabilities assumed are recorded by BD at their estimated fair values as of the date the CareFusion Acquisition is completed. Any excess of the purchase price over the fair value of identified assets acquired and liabilities assumed is recognized as goodwill. The purchase price allocation adjustments are estimates and may be further refined as additional information becomes available following completion of the CareFusion Acquisition.

The unaudited pro forma condensed combined financial information has been prepared by management in accordance with the regulations of the SEC and is not necessarily indicative of the condensed consolidated financial position or results of operations that would have been realized had the CareFusion Acquisition occurred as of the dates indicated above, nor is it meant to be indicative of any anticipated condensed consolidated financial position or future results of operations that the combined company will experience after the CareFusion Acquisition. As required, the unaudited pro forma condensed combined financial information includes adjustments which give effect to events that are directly attributable to the CareFusion Acquisition and are factually supportable; as such, any planned adjustments affecting the balance sheet, income statement, or shares of common stock outstanding subsequent to the CareFusion Acquisition completion date are not included. The accompanying unaudited pro forma condensed combined income statement also does not include any expected cost savings or restructuring actions which may be achievable subsequent to the CareFusion Acquisition or the impact of any non-recurring activity and one-time transaction related costs.

The acquisition closed on March 17, 2015. The value of the consideration transferred for accounting purposes is based on the closing share price of BD’s stock on the last trading day prior to the closing date of the transaction.

The unaudited pro forma condensed combined financial information is derived from and should be read in conjunction with (i) the audited consolidated financial statements (and notes thereto) of BD for the years ended September 30, 2014, 2013 and 2012 (which are available in BD’s Annual report on Form 10-K for the fiscal year ended September 30, 2014, as revised by Exhibit 99.2 to BD’s Current Report on Form 8-K, filed with the SEC on March 13, 2015) and the unaudited condensed consolidated financial statements (and notes thereto) of BD for the three month period ended December 31, 2014 (which are available in BD’s Quarterly Report on Form 10-Q for the three month period ended December 31, 2014) and (ii) the audited consolidated financial statements (and notes thereto) of CareFusion for the years ended June 30, 2014, 2013 and 2012 and the unaudited condensed consolidated financial statements (and

notes thereto) of CareFusion for the three month period ended September 30, 2014 (which are both available as Exhibit 99.1 to BD’s Current Report on Form 8-K, filed with the SEC on December 4, 2014) and the unaudited condensed consolidated financial statements (and notes thereto) of CareFusion for the six month period ended December 31, 2014 (which are available as Exhibit 99.2 to this Current Report on Form 8-K).

FOR THE FISCAL YEAR ENDED SEPTEMBER 30, 2014

Note 1 – Description of CareFusion Acquisition

On October 5, 2014, BD announced a definitive agreement under which BD will acquire CareFusion for $58 per share in cash and stock to create a global leader in medication management and patient safety solutions. The acquisition closed on March 17, 2015.

Pursuant to the agreement, BD acquired 100 percent of CareFusion at a purchase consideration of approximately $12.6 billion as follows:

Under the terms of the transaction, CareFusion shareholders will receive $49.00 in cash and 0.0777 of a share of BD for each share of CareFusion. The value of the consideration transferred for accounting purposes is based on the closing share price of BD’s stock on the last trading day prior to the closing date of the transaction, or $142.29.

Note 2 – Basis of Pro Forma Presentation

The unaudited pro forma condensed combined financial information shows the impact of the CareFusion Acquisition on the combined balance sheet and the combined statements of income under the acquisition method of accounting with BD treated as the acquirer. The acquisition method of accounting, provided by ASC 805 Business Combinations, uses the fair value concepts defined in ASC 820 Fair Value Measurement. Under this method of accounting, the assets and liabilities of CareFusion are recorded by BD at the date of the CareFusion Acquisition estimated fair values, where fair value is defined in ASC 820 as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” The fair values of CareFusion’s identifiable tangible and intangible assets acquired and liabilities assumed are based on fair value estimates as if the businesses had actually been combined as of December 31, 2014. Any excess of the purchase price over the fair value of identified assets acquired and liabilities assumed will be recognized as goodwill. Fair value measurements may require extensive use of significant estimates and management’s judgment, and it is possible the application of reasonable judgment could produce varying results based on a range of alternative estimates using the same facts and circumstances. Since the CareFusion Acquisition has just been consummated, our access to information to make such estimates is limited. As such, certain market based assumptions were used when data was not available; however, management believes the fair values recognized for the assets to be acquired and liabilities to be assumed are based on reasonable estimates and assumptions. Subsequent to the CareFusion Acquisition completion date, there may be further refinements of the business combination adjustments as additional information

becomes available. Increases or decreases in fair value of certain balance sheet amounts and other items of CareFusion as compared to the information presented here may change the amount of the business combination adjustments to goodwill and other assets and liabilities and may impact the income statement due to adjustments in yield and/or amortization of adjusted assets and liabilities.

Note 3 – Conforming Accounting Policies

Following the CareFusion Acquisition, BD will conduct a review of CareFusion’s accounting policies in an effort to determine if differences in accounting policies require reclassification of CareFusion’s results of operations or reclassification of assets or liabilities to conform to BD’s accounting policies and classifications. As a result of that review, BD may identify differences between the accounting policies of the two companies that, when conformed, could have a material impact on these pro forma condensed combined financial statements. During the preparation of these unaudited pro forma condensed combined financial statements, BD was not aware of any material differences between accounting policies of the two companies and accordingly, these unaudited pro forma condensed combined financial statements do not assume any material differences in accounting policies between the two companies.

Note 4 – Reclassifications

Certain balances from the consolidated financial statements of CareFusion were reclassified to conform their presentation to that of BD:

The following reclassifications were made to the unaudited pro forma condensed combined balance sheet as of December 31, 2014 (in millions):

The following reclassifications were made to the unaudited pro forma condensed combined income statements for the year fiscal year ended September 30, 2014 and for the three months ended December 31, 2014 (in millions):

Note 5 - Unaudited Pro Forma Condensed Combined Balance Sheet Adjustments

This note should be read in conjunction with “Note 1 - Description of CareFusion Acquisition”, “Note 2 - Basis of Pro Forma Presentation”, “Note 3 - Conforming Accounting Policies”, and “Note 4 –Reclassifications.” Adjustments included in the columns “Acquisition Adjustments” and “Financing Adjustments” to the accompanying unaudited pro forma condensed combined balance sheet as at December 31, 2014 are represented, in part, by the following considerations arising out of the allocation of the purchase price to CareFusion’s assets and liabilities (in millions):

The cash consideration will be partially funded by $6.2 billion of senior unsecured notes issued in December 2014. The remaining balance will be funded by available cash and $500 million of commercial paper and $1 billion of a term loan facility. In connection with obtaining the debt financing, $43 million of deferred financing costs have been recorded as of December 31, 2014 and $2 million of deferred financing costs are

expected to be capitalized and amortized over the life of the underlying debt. In addition, $8 million of costs related to BD’s bridge financing are reflected as a reduction of cash with a corresponding decrease to retained earnings.

Identifiable intangible assets expected to be acquired consist of the following (in millions):

The fair value estimate for identifiable intangible assets is preliminary and is determined based on the assumptions that market participants would use in pricing an asset, based on the most advantageous market for the asset (i.e., its highest and best use). This preliminary fair value estimate could include assets that are not intended to be used, may be sold or are intended to be used in a manner other than their best use. For purposes of the accompanying unaudited pro forma condensed combined financial information, it is assumed that all assets will be used in a manner that represents their highest and best use. The final fair value determination for identifiable intangibles may differ from this preliminary determination.

This adjustment represents an increase in book value for CareFusion’s inventory and property, plant, and equipment balances of $176 million, and $83 million, respectively, to reflect fair value.

The fair value estimate for inventory and property, plant, and equipment is preliminary and is determined based on the assumptions that market participants would use in pricing an asset, based on the most advantageous market for the asset (i.e., its highest and best use). This preliminary fair value estimate could include assets that are not intended to be used, may be sold or are intended to be used in a manner other than their best use. For purposes of the accompanying unaudited pro forma condensed combined financial information, it is assumed that all assets will be used in a manner that represents their highest and best use. The final fair value determination for inventories and property, plant, and equipment may differ from this preliminary determination.

To record the fair value step-up of $145 million on CareFusion’s existing debt, which will remain outstanding after the acquisition at fair value.

To record the fair value step-up of $14 million on CareFusion’s dispensing equipment, which is presented in the “Other assets” line item on the accompanying unaudited pro forma condensed combined balance sheet, and a write down of CareFusion’s deferred revenue of $45 million, which is presented in the “Payables and accrued expenses” line item on the unaudited pro forma condensed combined balance sheet. Deferred revenue was reduced to reflect the assumed performance obligation at fair value.

Reflects the adjustment to deferred income tax assets of $35 million and liabilities of $1,955 million resulting from pro forma fair value adjustments for the assets and liabilities to be acquired. This estimate of deferred taxes was determined based on the excess book basis over the tax basis of the fair value pro forma adjustments attributable to the assets and liabilities to be acquired. The U.S. statutory tax rate was applied to each adjustment as the majority of fair value adjustments relate to entities domiciled in the United States. This estimate of deferred income tax assets and liabilities is preliminary and is subject to change based upon management’s final determination of the fair value of assets acquired and liabilities assumed by jurisdiction.

Goodwill is calculated as the difference between the fair value of the consideration transferred and the values assigned to the identifiable tangible and intangible assets acquired and liabilities assumed. The amount of goodwill presented in the above table reflects the estimated goodwill as a result of the acquisition of $6.8 billion as of December 31, 2014. This amount, reduced by CareFusion’s existing goodwill at December 31, 2014 of $3.3 billion resulted in an acquisition accounting adjustment in the unaudited pro forma condensed combined balance sheet as of December 31, 2014 of $3.5 billion.

Note 6 - Unaudited Pro Forma Condensed Combined Income Statement Adjustments

This note should be read in conjunction with “Note 1 - Description of CareFusion Acquisition”, “Note 2 - Basis of Pro Forma Presentation”, “Note 3 - Conforming Accounting Policies”, “Note 4 - Reclassifications”, and “Note 5 - Unaudited Pro Forma Condensed Combined Balance Sheet Adjustments”. Adjustments included in the columns “Acquisition Adjustments” and “Financing Adjustments” to the accompanying unaudited pro forma condensed combined income statement for the three months ended December 31, 2014 are represented by the following:

This adjustment represents the increased amortization for the fair value of identified intangible assets with definite lives for the fiscal year ended September 30, 2014 and the three months ended December 31, 2014. The following table shows the pre-tax impact on amortization expense (amounts in millions):

The adjustment to selling and administrative expense of $7 million and $28 million for the three months ended December 31, 2014 and fiscal year ended September 30, 2014 is related to fair value step up and corresponding increased depreciation of property, plant, and equipment. The income statement effect of the fair value step-up to increase the book value of CareFusion’s inventory is not reflected as such adjustment is not recurring in nature.

This adjustment represents the additional interest expense for the fiscal year ended September 30, 2014 and the three months ended December 31, 2014 taking into consideration the additional borrowings incurred by BD for financing the CareFusion Acquisition as well as the accretion on the fair value step-up on CareFusion’s existing debt. Refer to the table below for the breakdown of this amount (in millions):

This adjustment represents the tax effects of all the adjustments described in Notes 6a and 6b above using BD’s statutory rate.

Note 7 – Unadjusted Pro Forma Balances

Trade receivables and sales-type leases

At this time, BD does not have sufficient information necessary to make a reasonable preliminary estimate of the fair value of CareFusion’s trade receivables and sales-type leases. Therefore, no adjustment has been recorded to modify the current book values.

Deferred tax liabilities

CareFusion does not record deferred taxes on the unremitted earnings of subsidiaries outside of the United States, when it is expected that these earnings will be indefinitely reinvested. At this time, BD does not have sufficient information necessary to make any changes to this assertion. Therefore, there have been no adjustments reflected in the book value of deferred tax liabilities related to this assertion in the accompanying unaudited pro forma condensed combined financial statements. The deferred tax assets recorded on the unaudited pro forma condensed combined balance sheet have not been assessed for the need of a valuation allowance.
