Griffin Sub, Inc.

c/o Becton, Dickinson and Company

1 Becton Drive

Franklin Lakes, New Jersey 07417

(201) 847-6800

Griffin Sub, Inc., a Delaware corporation and a wholly owned subsidiary of BD, which we refer to as Merger Corp, was formed solely for the purpose of facilitating the merger. Merger Corp has not carried on any activities or operations to date, except for those activities incidental to its formation and undertaken in connection with the transactions contemplated by the merger agreement. By operation of the merger, Merger Corp will be merged with and into CareFusion, with CareFusion surviving the merger as a wholly owned subsidiary of BD.

The Merger and the Merger Agreement (Page 54 and Annex A)

The terms and conditions of the merger are contained in the merger agreement, a copy of which is attached as Annex A to this proxy statement/prospectus. We encourage you to read the merger agreement carefully and in its entirety, as it is the legal document that governs the merger.

Pursuant to the merger agreement, Merger Corp will merge with and into CareFusion. After the effective time, CareFusion will be the surviving company and a wholly owned subsidiary of BD.

Per Share Merger Consideration (Page 54)

Upon completion of the merger, each issued and outstanding share of CareFusion common stock, other than shares owned by BD or CareFusion, or by stockholders that have perfected and not withdrawn a demand for appraisal rights pursuant to Section 262 of the DGCL, will be converted into the right to receive (i) $49.00 in cash, without interest, which we refer to as the cash consideration, and (ii) 0.0777 of a share of common stock, par value $1.00 per share, of BD, which we refer to as the exchange ratio. We refer to (i) and (ii) together as the per share merger consideration.

In the event that the outstanding shares of CareFusion common stock or BD common stock are changed into a different number of shares or a different class of shares by reason of any reclassification, stock split (including a reverse stock split), recapitalization, split-up, combination, exchange of shares, readjustment, or other similar transaction, or a stock dividend thereon shall be declared with a record date within said period, then the exchange ratio will be appropriately adjusted to provide BD and the CareFusion common stock holders (including holders of CareFusion stock options, restricted stock units and performance stock units) the same economic effect as prior to the event.

Treatment of CareFusion Equity Awards (Page 90)

Treatment of Stock Options

Each CareFusion option that is outstanding immediately prior to the effective time, whether vested or unvested including any such option held by an executive officer or non-employee director, will be converted at the effective time into an option to purchase, on the same terms and conditions as were applicable to such CareFusion option immediately prior to the effective time, the number of shares of BD common stock (rounded down to the nearest whole share) determined by multiplying the number of shares of CareFusion common stock subject to the CareFusion option by the stock award exchange ratio (as defined below), at an exercise price per share (rounded up to the nearest whole cent) determined by dividing the per share exercise price of the CareFusion option by the stock award exchange ratio. The stock award exchange ratio is the sum of (i) the exchange ratio and (ii) the quotient of the cash consideration divided by BD’s volume-weighted average stock price for the five trading days immediately preceding the closing date.

Treatment of Unvested Restricted Stock Units

At the effective time, each CareFusion restricted stock unit that is outstanding and unvested immediately prior to the effective time and does not vest by its terms at the effective time (including any such restricted stock unit held by an executive officer) will be converted into a BD restricted stock unit, with the same terms and conditions as were applicable under such unvested CareFusion restricted stock unit immediately prior to the effective time, and relating to the number of shares of BD common stock (rounded to the nearest whole share), determined by multiplying (i) the number of shares of CareFusion common stock subject to such unvested restricted stock unit immediately prior to the effective time by (ii) the stock award exchange ratio. Restricted stock unit awards granted to officers of the Company on August 15, 2014 that have a performance condition relating to the Company’s fiscal year will be treated as described in the previous sentence, and the applicable performance goal will be certified as achieved by the compensation committee prior to the time of closing.

Treatment of Unvested Performance Stock Units

At the effective time, each CareFusion performance stock unit that is outstanding and unvested immediately prior to the effective time and does not vest by its terms at the effective time (including any such performance stock unit held by an executive officer) will be converted into a BD restricted stock unit, with the same terms and conditions as were applicable under such unvested CareFusion performance stock unit immediately prior to the effective time (except that the performance-based vesting conditions applicable to such unvested performance stock unit immediately prior to the effective time shall not apply from and after the effective time), and relating to the number of shares of BD common stock (rounded to the nearest whole share), determined by multiplying (i) the number of shares of CareFusion common stock subject to such unvested performance stock unit award immediately prior to the effective time by (ii) the stock award exchange ratio. For this purpose, the number of shares of CareFusion common stock subject to each such unvested CareFusion performance stock unit shall be equal to the number of shares earned based on the level of achievement, as certified by the compensation committee prior to the time of closing, of the applicable performance condition measured through the end of CareFusion’s most recently completed calendar quarter prior to the time of closing, but shall not be less than the target number of shares.

Treatment of Vested Restricted Stock Units and Performance Stock Units

At the effective time, each CareFusion restricted stock unit and CareFusion performance stock unit that is outstanding immediately prior to the effective time and becomes vested by its terms at the effective time (including any such restricted stock unit held by a non-employee director and any such performance stock unit held by an executive officer), and each CareFusion restricted stock unit held by a non-employee director, settlement of which was elected to be deferred, shall be cancelled and converted into, with respect to each share of CareFusion common stock subject to such restricted stock unit or performance stock unit (provided, that, each such performance stock unit shall, in accordance with its terms, vest based on the greater of target performance and actual performance through the closing date, as certified by the compensation committee prior to the time of closing), the merger consideration on the same terms and conditions as other shares of CareFusion common stock, subject to applicable tax withholding, with such tax withholding to be withheld pro rata from the cash consideration and the stock consideration (with the stock consideration valued, for such purpose, based on the closing price of BD common stock on the closing date).

Financing of the Merger (Page 82)

BD anticipates that the funds needed to complete the transactions contemplated by the merger agreement will be derived from a combination of (i) the issuance of common stock of BD to CareFusion’s stockholders, (ii) available cash on hand of BD and CareFusion, (iii) borrowings under BD’s commercial paper program, and (iv) third party debt financing, which we refer to as the debt financing, which is expected to include a combination of the following: (a) a senior unsecured term loan facility, (b) the issuance of senior unsecured notes or other debt securities, and/or (c) a senior unsecured bridge loan facility.

On November 26, 2014, BD obtained a debt commitment letter, which we refer to as the debt commitment letter, from Goldman Sachs Bank USA, J.P. Morgan Securities LLC and JPMorgan Chase Bank, N.A., which we refer to collectively as the commitment parties, pursuant to which the commitment parties have agreed to provide a $1.0 billion senior unsecured 364-day term loan facility, which we refer to as the term loan facility.

Each commitment party’s commitments with respect to the term loan facility and each commitment party’s agreements to perform the services described in the debt commitment letter, will automatically terminate on the earliest of (i) 11:59 pm on July 5, 2015 (or 11:59 pm on October 5, 2015 if the end date (as defined in the merger agreement, see the section entitled “The Merger Agreement—Termination of the Merger Agreement—Termination” on page 103 of this proxy statement/prospectus) is extended to October 5, 2015), (ii) the consummation of the merger, (iii) the termination of the merger agreement in accordance with its terms, or (iv) the date on which the loan agreement with respect to the term loan facility, which we refer to as the term loan agreement, has been executed and delivered by each of the parties thereto and all conditions precedent to its effectiveness have been satisfied.

The obligation of the commitment parties to provide debt financing under the debt commitment letter is subject to a number of conditions. There is a risk that these conditions will not be satisfied and the debt financing may not be available when required. In the event that the term loan facility is not available to BD on the terms set forth in the debt commitment letter or BD anticipates that the term loan facility will not be available on the terms set forth in the debt commitment letter due to the failure of a condition thereto or for any other reason, BD has the right under the merger agreement, subject to certain conditions and limitations, to seek alternative financing. As of the date of this proxy statement/prospectus, no such alternative financing has been arranged. BD’s obligation to complete the merger is not conditioned upon the receipt of any financing.

As disclosed in the Form 8-K filed on November 14, 2014, on November 14, 2014, BD entered into a senior unsecured bridge term loan agreement, which we refer to as the bridge loan agreement, by and among BD, as borrower, Goldman Sachs Bank USA, as administrative agent and the lenders party thereto pursuant to which the lenders under the bridge loan agreement have agreed to provide a $9.1 billion senior unsecured bridge loan facility, which we refer to as the bridge loan facility, subject to conditions substantially similar to the conditions to the term loan facility. The commitments of the lenders under the bridge loan facility were automatically reduced in an amount equal to the net cash proceeds of the senior unsecured notes issued as described below and will be further reduced by the aggregate amount of the commitments under the term loan facility at the time a loan agreement is executed in connection with the term loan facility.

On December 15, 2014, BD issued $6.2 billion aggregate principal amount of senior unsecured notes comprised of: (i) $750 million aggregate principal amount of floating rate notes due June 15, 2016, (ii) $1.25 billion aggregate principal amount of 1.800% notes due December 15, 2017, (iii) $1.25 billion aggregate principal amount of 2.675% notes due December 15, 2019, (iv) $1.75 billion aggregate principal amount of 3.734% notes due December 15, 2024 and (v) $1.2 billion aggregate principal amount of 4.685% notes due December 15, 2044 in an underwritten public offering pursuant to the indenture, dated March 1, 1997, between BD and The Bank of New York Mellon Trust Company, N.A., as trustee. The net proceeds of the offering will be used to fund the transactions contemplated by the merger agreement.

Recommendation of the CareFusion Board of Directors; CareFusion’s Reasons for the Merger (Page 64)

After careful consideration of various factors described in the section entitled “The Merger—Recommendation of the CareFusion Board of Directors; CareFusion’s Reasons for the Merger” beginning on page 64 of this proxy statement/prospectus, at a meeting held on October 5, 2014, the CareFusion board of directors unanimously (i) determined that the merger agreement and the transactions contemplated thereby are fair to and in the best interests of CareFusion’s stockholders, (ii) approved and declared advisable the merger agreement and the transactions contemplated thereby and (iii) resolved to recommend adoption of the merger agreement by CareFusion’s stockholders.

Opinion of CareFusion’s Financial Advisor (Page 67 and Annex B)

Perella Weinberg Partners LP, which we refer to as Perella Weinberg, rendered its oral opinion, subsequently confirmed in writing, to the CareFusion board of directors that, as of October 5, 2014, and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth in the written opinion, the merger consideration to be received by the holders of CareFusion common stock (other than shares of CareFusion common stock that are owned, directly or indirectly, by BD, CareFusion (including shares held as treasury stock or otherwise) or Merger Corp immediately prior to the effective time of the Merger and shares held by CareFusion stockholders properly exercising appraisal rights under the DGCL, collectively “CareFusion excluded shares”) pursuant to the merger agreement was fair, from a financial point of view, to such holders.

The full text of Perella Weinberg’s written opinion, dated October 5, 2014, which sets forth, among other things, the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by Perella Weinberg, is attached as Annex B and is incorporated by reference herein.

Holders of CareFusion common stock are urged to read Perella Weinberg’s opinion carefully and in its entirety. The opinion does not address CareFusion’s underlying business decision to enter into the merger or the relative merits of the merger as compared with any other strategic alternative which may be available to CareFusion. The opinion was not intended to be and does not constitute a recommendation to any holder of CareFusion common stock as to how such holder should vote or otherwise act with respect to the merger or any other matter. The opinion does not in any manner address the prices at which the CareFusion common stock or BD common stock will trade at any time. In addition, Perella Weinberg expressed no opinion as to the fairness of the merger to, or any consideration received in connection with the merger by, the holders of any other class of securities, creditors or other constituencies of CareFusion. Perella Weinberg provided its opinion for the information and assistance of the CareFusion board of directors in connection with, and for the purposes of its evaluation of, the merger. This summary is qualified in its entirety by reference to the full text of the opinion.

For a description of the opinion that the CareFusion board of directors received from Perella Weinberg, see “The Merger—Opinion of CareFusion’s Financial Advisor” beginning on page 67 of this proxy statement/prospectus.

Information About the Special Meeting (Page 49)

Time, Place and Purpose of the Special Meeting (Page 49)

The special meeting to consider and vote upon the adoption of the merger agreement, which we refer to as the special meeting, will be held on January 21, 2015, at 8:30 a.m. (Pacific Standard time) local time, at CareFusion Headquarters, located at 3750 Torrey View Court, San Diego, CA, 92130.

At the special meeting, CareFusion stockholders will be asked to consider and vote upon (i) a proposal to adopt the merger agreement, (ii) a proposal to approve, by advisory (non-binding) vote, certain compensation arrangements for CareFusion’s named executive officers in connection with the merger and (iii) a proposal for adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to adopt the merger agreement.

Record Date and Quorum (Page 49)

You are entitled to receive notice of, and to vote at, the special meeting if you are an owner of record of shares of CareFusion common stock as of the close of business on December 18, 2014, the record date. On the record date, there were 204,200,436 shares of CareFusion common stock outstanding and entitled to vote. You will have one vote on all matters properly coming before the special meeting for each share of CareFusion common stock that you owned on the record date.

The presence, in person or represented by proxy, of holders of a majority of all of the outstanding shares of CareFusion common stock entitled to vote at the special meeting constitutes a quorum for the purposes of the special meeting. Abstentions are considered for purposes of establishing a quorum.

Vote Required (Page 49)

The adoption of the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares of CareFusion common stock entitled to vote thereon. Votes to abstain will not be counted as votes cast in favor of the adoption of the merger agreement, but will count for the purpose of determining whether a quorum is present. If you fail to submit a proxy or to vote in person at the special meeting or you vote to abstain, this will have the same effect as a vote “AGAINST” the adoption of the merger agreement.

The proposal to approve certain compensation arrangements for CareFusion’s named executive officers in connection with the merger requires the affirmative vote of the holders of a majority of shares of CareFusion common stock present in person or represented by proxy and entitled to vote thereon; however, such vote is

advisory (non-binding) only. If your shares of CareFusion common stock are present at the special meeting but are not voted on the proposal, or if you vote to abstain on the proposal, each will have the effect of a vote “AGAINST” the merger-related executive compensation proposal. If you fail to submit a proxy and fail to attend the special meeting, or if you do not instruct your bank, brokerage firm or other nominee to vote your shares of CareFusion common stock in favor of the proposal, your shares of CareFusion common stock will not be voted, but this will not have an effect on the advisory (non-binding) vote to approve the merger-related executive compensation, except to the extent it results in there being insufficient shares present at the meeting to establish a quorum.

The approval of adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to adopt the merger agreement requires the affirmative vote of the holders of a majority of shares of CareFusion common stock present in person or represented by proxy and entitled to vote thereon, whether or not a quorum is present. If your shares of CareFusion common stock are present at the special meeting but are not voted on the proposal, or if you vote to abstain on the proposal, each will have the effect of a vote “AGAINST” adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to adopt the merger agreement. If you fail to submit a proxy and fail to attend the special meeting or if your shares of CareFusion common stock are held through a bank, brokerage firm or other nominee and you do not instruct your bank, brokerage firm or other nominee to vote your shares of CareFusion common stock, your shares of CareFusion common stock will not be voted, but this will not have an effect on the vote to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to adopt the merger agreement.

Proxies and Revocations (Page 50)

Any stockholder of record entitled to vote at the special meeting may submit a proxy by telephone, over the Internet, by returning the enclosed proxy card in the accompanying prepaid reply envelope or may vote in person by appearing at the special meeting. If your shares of CareFusion common stock are held in “street name” through a bank, brokerage firm or other nominee, you should instruct your bank, brokerage firm or other nominee on how to vote your shares of CareFusion common stock using the instructions provided by your bank, brokerage firm or other nominee. If you fail to submit a proxy or to vote in person at the special meeting, or do not provide your bank, brokerage firm or other nominee with instructions as to how to vote your shares, as applicable, your shares of CareFusion common stock will not be voted on the adoption of the merger agreement, which will have the same effect as a vote “AGAINST” the adoption of the merger agreement and your shares of CareFusion common stock will not have an effect on the proposal to approve, by advisory (non-binding) vote, the merger-related executive compensation (other than to the extent resulting in failure to establish a quorum) or on the vote to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to adopt the merger agreement.

You have the right to revoke a proxy, whether delivered over the Internet, by telephone or by mail, at any time before it is exercised, by voting again at a later date through any of the methods available to you, by attending the special meeting and voting in person, or by giving written notice of revocation to CareFusion prior to the time the special meeting begins. Written notice of revocation should be mailed to: CareFusion Corporation, 3750 Torrey View Court, San Diego, CA 92130, Attention: Corporate Secretary.

Interests of CareFusion’s Directors and Executive Officers in the Merger (Page 107)

Non-employee directors and executive officers of CareFusion have certain interests in the merger that may be different from or in addition to the interests of CareFusion stockholders generally. These interests include, among others, potential severance benefits and other payments, the treatment of outstanding equity awards pursuant to the merger agreement, and rights to ongoing indemnification and insurance coverage. The CareFusion board of directors was aware of and considered those interests, among other matters, in reaching its decisions to (i) approve the merger and the other transactions contemplated thereby, (ii) adopt, approve and

declare advisable the merger agreement, and (iii) resolve to recommend the adoption of the merger agreement to CareFusion stockholders. See the section entitled “Interests of CareFusion’s Directors and Executive Officers in the Merger” beginning on page 107 of this proxy statement/prospectus for a more detailed description of these interests.

Regulatory Approvals (Page 83)

Completion of the merger is conditioned upon (i) the expiration or early termination of the applicable waiting period under the HSR Act and (ii) the adoption or deemed adoption of approvals of the merger by the European Commission under the EUMR. BD and CareFusion each filed their respective HSR Act notification forms on October 20, 2014, and the 30-day waiting period expired on November 19, 2014. BD has filed a draft EUMR notification form and anticipates filing its final EUMR notification form in the near term.

Subject to the terms of the merger agreement, CareFusion and BD have agreed to cooperate with each other and to use their respective reasonable best efforts to obtain all regulatory approvals required to complete the merger. Each of CareFusion and BD has agreed, to the extent necessary to resolve objections, if any, that a governmental authority of competent jurisdiction asserts with respect to any required antitrust or similar competition approval under any applicable law with respect to the merger, and to avoid or eliminate all impediments under any applicable antitrust or similar competition law asserted by any such governmental authority of competent jurisdiction with respect to the merger so as to permit the closing to occur by the end date (as defined in the merger agreement, see the section entitled “The Merger Agreement—Termination of the Merger Agreement—Termination” on page 103 of this proxy statement/prospectus), to (i) propose, negotiate, effect the sale, divestiture, license, or other disposition of any business, assets, equity interests, product lines or properties of BD or CareFusion (or either party’s respective subsidiaries), (ii) create, terminate or divest relationships, contractual rights or obligations of BD or CareFusion (or either party’s respective subsidiaries) and (iii) take or commit to take any action which limits BD’s right to retain directly or indirectly retain or hold any business, assets, equity interests product lines or properties, in each case as required in order to obtain any antitrust or similar competition approval so as to permit the closing to occur by the end date.

However, in no event will BD or any of its subsidiaries be required to, and CareFusion and its subsidiaries will not, without the prior written consent of BD, take any action, or agree to any condition or limitation that (i) would, or would reasonably be expected to, have a material adverse effect on the business, results of operations, or financial condition of either BD and its subsidiaries or CareFusion and its subsidiaries (in each case measured on a scale relative to CareFusion and its subsidiaries, taken as a whole), (ii) would, or would be reasonably likely to, individually or in the aggregate, result in a loss of 50% or more of net sales revenue (measured by net sales revenue for the trailing twelve month period) to BD’s and its subsidiaries’ intravenous which we refer to as “IV” catheter business conducted in the United States, (iii) would, or would be reasonably likely to, individually or in the aggregate, result in a loss of 50% or more of net sales revenue (measured by net sales revenue for the trailing twelve month period) to BD’s and its subsidiaries’ IV catheter business conducted outside the United States or (iv) in order to avoid the entry of, or to effect the dissolution of, any competition law order in a jurisdiction other than the United States or the European Union, would require BD to take any action with respect to any business, properties or assets of BD and its subsidiaries, or CareFusion and its subsidiaries, located outside of the home country of the governmental authority of competent jurisdiction in respect of such a competition law order.

Appraisal Rights of CareFusion Stockholders (Page 132 and Annex C)

CareFusion stockholders of record have appraisal rights under the DGCL in connection with the merger. CareFusion stockholders who do not vote in favor of the adoption of the merger agreement and who otherwise comply with the applicable provisions of Section 262 of the DGCL will be entitled to exercise appraisal rights thereunder. Any shares of CareFusion common stock held by a CareFusion stockholder as of the record date who has not voted in favor of the adoption of the merger agreement and who has demanded appraisal for such shares

in accordance with the DGCL will not be converted into a right to receive the merger consideration, unless such CareFusion stockholder fails to perfect, withdraws or otherwise loses such stockholder’s appraisal rights under the DGCL. If, after the consummation of the merger, such holder of CareFusion common stock fails to perfect, withdraws or otherwise loses his, her or its appraisal rights, each such share will be treated as if it had been converted as of the consummation of the merger into a right to receive the merger consideration. The relevant provisions of the DGCL are included as Annex C to this proxy statement/prospectus.

You are encouraged to read these provisions carefully and in their entirety. Due to the complexity of the procedures for exercising your appraisal rights, CareFusion stockholders who are considering exercising such rights are encouraged to seek the advice of legal counsel. Failure to strictly comply with these provisions will result in the loss of appraisal rights. See the section entitled “Appraisal Rights of CareFusion Stockholders” beginning on page 132 of this proxy statement/prospectus for additional information and the text of Section 262 of the DGCL reproduced in its entirety as Annex C to this proxy statement/prospectus.

Conditions to Completion of the Merger (Page 102)

In addition to the approval of the merger proposal by CareFusion stockholders, the expiration or termination of the applicable waiting period under the HSR Act and adoption or deemed adoption of approvals of the merger by the European Commission under the EUMR, each as described above, each party’s obligation to complete the merger is also subject to the satisfaction or waiver (to the extent permitted under applicable law) of certain other conditions, including the effectiveness of the registration statement on Form S-4 of which this proxy statement/prospectus forms a part (and the absence of any stop order by the SEC), approval of the listing on the NYSE of the BD common stock to be issued in the merger, the absence of an injunction prohibiting the merger, the accuracy of the representations and warranties of the other party under the merger agreement (subject to the materiality standards set forth in the merger agreement), the performance by the other party of its respective obligations under the merger agreement in all material respects and delivery of officer certificates by the other party certifying satisfaction of the two preceding conditions. The waiting period under the HSR Act expired on November 19, 2014, satisfying the HSR Act waiting period condition.

Neither CareFusion nor BD can be certain when, or if, the conditions to the merger will be satisfied or waived, or that the merger will be completed. For a more complete summary of the conditions that must be satisfied or waived prior to completion of the merger, see the section entitled “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 102 of this proxy statement/prospectus.

No Solicitation (Page 96)

As more fully described in this proxy statement/prospectus and in the merger agreement, and subject to the exceptions summarized below, CareFusion has agreed that it will not (1) solicit, initiate, knowingly encourage, or take any other action designed to facilitate, any inquiries regarding, or the making or submission of any inquiry, proposal or indication of interest or offer that constitutes, or would reasonably be expected to lead to, a company acquisition proposal (as defined in the merger agreement); (2) approve or recommend, or propose to approve or recommend, a company acquisition proposal; (3) approve or recommend, or propose to approve or recommend, or execute or enter into any letter of intent, memorandum of understanding, merger agreement or other agreement, arrangement or understanding relating to a company acquisition proposal (other than a confidentiality agreement in connection with a company acquisition proposal) or a superior proposal (as defined in the merger agreement); (4) enter into, continue or otherwise participate in any discussions or negotiations regarding any company acquisition proposal; or (5) agree to do any of the foregoing actions.

Under the terms of the merger agreement, CareFusion agreed to immediately cease any discussions or negotiations with any person that may have been ongoing with respect to a company acquisition proposal as of October 5, 2014. CareFusion agreed to promptly advise BD of any inquiries, proposals or offers with respect to a company acquisition proposal that are received by, or any non-public information with regard to such proposal is requested from, or any discussions or negotiations sought to be initiated regarding such proposal with, CareFusion or its representatives.

If, prior to obtaining the CareFusion stockholder approval, following the receipt of a bona fide written company acquisition proposal that the CareFusion board of directors determines in good faith, after consultation with CareFusion’s outside financial advisors and outside legal counsel, is or could reasonably be expected to lead to a superior proposal and that was unsolicited and made after October 5, 2014 in circumstances not otherwise involving a breach of the merger agreement, CareFusion may, in response to such company acquisition proposal, furnish information with respect to CareFusion to the person making such company acquisition proposal and engage in discussions or negotiations with such person, except that prior to furnishing any such nonpublic information relating to CareFusion, CareFusion enters into a confidentiality agreement with the person making the company acquisition proposal that (x) does not contain any provision that would prevent CareFusion from complying with its obligation to provide any disclosure to BD required pursuant to the merger agreement and (y) contains provisions that in the aggregate are no less restrictive on such person (including with respect to any “standstill” terms, except that such “standstill” terms need not restrict a person from making proposals to CareFusion or its board of directors in respect of a company acquisition proposal) than those contained in the confidentiality agreement between CareFusion and BD, and promptly (but in any event within 24 hours) following the furnishing of any such nonpublic information to such person, CareFusion furnishes such nonpublic information to BD (to the extent such nonpublic information has not been previously furnished to BD).

No Change in Recommendation or Entry into Alternative Acquisition Agreement (Page 98)

Subject to certain exceptions described below, the CareFusion board of directors may not:

Fiduciary Exception

However, at any time before the CareFusion stockholder approval is obtained, but not after it is obtained, if (i) an unsolicited written company acquisition proposal is made by a third party, which CareFusion’s board of directors determines in good faith, after consultation with its financial advisor and outside legal counsel, constitutes a superior offer; or an intervening event (as defined in the merger agreement) occurs; (ii) in the case of a company acquisition proposal, CareFusion’s board of directors concludes in good faith, after consultation with CareFusion’s outside legal counsel and outside financial advisors, that such company acquisition proposal constitutes a superior proposal; and (iii) CareFusion’s board of directors concludes in good faith, after consultation with CareFusion’s outside legal counsel, that the failure to make a company adverse recommendation change would be reasonably likely to be inconsistent with its fiduciary duties under applicable laws, then, subject to the provisions described in the next paragraph, the CareFusion board of directors may effect a company adverse recommendation change.

Prior to making any company adverse recommendation change and/or authorization to enter into any alternative acquisition agreement, CareFusion’s board of directors must notify BD and negotiate in good faith with BD regarding any revisions or changes to the merger agreement or the merger proposed by BD in response to the superior proposal or intervening event, as applicable. If after such negotiations, CareFusion’s board of directors determines in good faith, after consultation with its financial advisors and outside legal counsel, that (x) the company acquisition proposal continues to be a superior proposal, or the intervening event continues to be an intervening event, warranting a company adverse recommendation change and (y) failure to make such recommendation would violate CareFusion’s fiduciary duties under applicable law, it may make such company adverse recommendation change and/or authorization to enter into any alternative acquisition agreement. Whether or not there is a company adverse recommendation change, unless the merger agreement is terminated, the CareFusion board of directors must submit the merger agreement for approval by the stockholders of CareFusion at the CareFusion special meeting. In the event there is a company adverse recommendation change

made in compliance with the merger agreement with respect to a superior proposal, CareFusion may only enter into an alternative acquisition agreement with respect to the superior proposal by concurrently terminating the merger agreement and paying BD the $367 million termination fee. We refer to this termination right as the fiduciary termination right.

Termination of the Merger Agreement (Page 103)

Termination

The merger agreement may be terminated and abandoned at any time prior to the effective time, whether before or after any approval of the merger by the holders of CareFusion common stock:

Termination Fee

CareFusion will pay BD fifty percent of the amount of BD’s out-of-pocket expenses incurred in connection with the merger agreement and the merger if the merger agreement is terminated by either BD or CareFusion because the CareFusion special meeting (as it may be adjourned or postponed) concluded without the CareFusion stockholder approval being obtained. In addition, CareFusion will pay BD a termination fee of $367 million (less

expense reimbursement payment, if any, described in the prior sentence) if the merger agreement is terminated in certain circumstances involving a company acquisition proposal. The expense reimbursement and termination fee could discourage other companies from seeking to acquire or merge with CareFusion.

Accounting Treatment (Page 84)

BD prepares its financial statements in accordance with accounting principles generally accepted in the United States, which we refer to as GAAP. The merger will be accounted for using the acquisition method of accounting. BD will be treated as the acquiror for accounting purposes.

Material U.S. Federal Income Tax Consequences (Page 115)

For U.S. holders (as such term is defined below under “Material U.S. Federal Income Tax Considerations”), the receipt of the merger consideration in exchange for shares of CareFusion common stock pursuant to the merger will generally be a taxable transaction for U.S. federal income tax purposes. CareFusion stockholders should consult their own tax advisors regarding the particular tax consequences of the exchange of shares of common stock for the merger consideration pursuant to the merger in light of their particular circumstances (including the application and effect of any state, local or foreign income and other tax laws). For a more detailed discussion of the material U.S. federal income tax consequences of the merger to CareFusion stockholders, please see the section titled “Material U.S. Federal Income Tax Consequences.”

Comparison of Stockholders’ Rights (Page 117)

The rights of CareFusion stockholders are governed by CareFusion’s amended and restated certificate of incorporation and amended and restated bylaws, which we refer to as the CareFusion charter and the CareFusion bylaws, respectively, and by Delaware corporate law. Your rights as a stockholder of BD will be governed by BD’s restated certificate of incorporation and bylaws, which we refer to as the BD charter and the BD bylaws, respectively, and by New Jersey corporate law. Your rights under the BD charter, BD bylaws and New Jersey corporate law will differ in some respects from your rights under the CareFusion charter, CareFusion bylaws and Delaware corporate law. For more detailed information regarding a comparison of your rights as a stockholder of CareFusion and BD, see the section entitled “Comparison of Stockholders’ Rights” beginning on page 117 of this proxy statement/prospectus.

Litigation Related to the Merger (Page 85)

Eight putative class action lawsuits have been filed against CareFusion, its directors, BD and Merger Corp in the Delaware Court of Chancery and in the Superior Court of California. These lawsuits generally allege that the members of the board of directors of CareFusion breached their fiduciary duties in connection with the merger by, among other things, carrying out a process that the plaintiffs allege did not ensure adequate and fair consideration to CareFusion stockholders and failing to disclose material information to CareFusion stockholders in this registration statement on Form S-4 of which this proxy statement/prospectus forms a part. The plaintiffs in these actions further allege that CareFusion, BD and Merger Corp aided and abetted the individual defendants’ breaches of their fiduciary duties. The plaintiffs seek, among other things, equitable relief to enjoin consummation of the merger, rescission of the merger and/or rescissory damages, and attorneys’ fees and costs. CareFusion, its directors, BD and Merger Corp intend to defend these actions vigorously.

SELECTED UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL DATA

The following selected unaudited pro forma financial data gives effect to the merger with CareFusion by BD. The selected pro forma data have been prepared using the acquisition method of accounting under U.S. generally accepted accounting principles, under which the assets and liabilities of CareFusion will be recorded by BD at their respective fair values as of the date the merger is completed. The selected Unaudited Pro Forma Condensed Combined Balance Sheet data as of September 30, 2014 gives effect to the transaction as if it had occurred on September 30, 2014. The selected Unaudited Pro Forma Condensed Combined Statement of Income data for the fiscal year ended September 30, 2014 gives effect as if the transaction had occurred on October 1, 2013, the beginning of BD’s fiscal year 2014.

The selected pro forma data have been derived from, and should be read in conjunction with, the more detailed unaudited pro forma condensed combined financial statements of the combined company appearing elsewhere in this proxy statement/prospectus and the accompanying notes to the pro forma statements. In addition, the pro forma statements were based on, and should be read in conjunction with, the historical consolidated financial statements of each of BD and CareFusion incorporated by reference into this proxy statement/prospectus. See “Where You Can Find More Information” and “Unaudited Pro Forma Condensed Combined Financial Statements” sections of this proxy statement/prospectus for additional information. The selected pro forma data has been presented for informational purposes only and is not necessarily indicative of what the combined company’s financial position or results of operations actually would have been had the merger been completed as of the dates indicated. In addition, the selected pro forma data does not purport to project the future financial position or operating results of the combined company. Also, as explained in more detail in the accompanying notes to the pro forma statements, the preliminary purchase price (consideration) and fair value assessment of assets and liabilities reflected in the selected pro forma data is subject to adjustment and may vary significantly from the final actual purchase price (consideration) and fair value assessment of assets and liabilities that will be recorded upon completion of the merger. Any excess of the purchase price over the fair value of identified assets acquired and liabilities assumed will be recognized as goodwill.

COMPARATIVE PER SHARE DATA

The following tables set forth historical per share information of BD and CareFusion and preliminary unaudited pro forma condensed combined per share information after giving effect to the merger with CareFusion by BD under the acquisition method of accounting. You should not rely on this information as being indicative of the historical results that would have been achieved had the companies always been combined or the future results that BD will experience after the acquisition of CareFusion. The preliminary unaudited pro forma condensed combined per share data has been derived from and should be read in conjunction with the “Unaudited Pro Forma Condensed Combined Financial Statements” beginning on page 28 and the related notes included in this proxy statement/prospectus beginning on page 31. The historical per share data has been derived from the historical consolidated financial statements of BD and CareFusion as of and for the periods indicated, incorporated by reference in this proxy statement/prospectus.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The unaudited pro forma condensed combined financial information and explanatory notes present how the combined balance sheet of BD and CareFusion may have appeared had the businesses actually been combined as of September 30, 2014, and is presented as if the merger with CareFusion, which we refer to as the merger, and the estimated borrowings used to finance the merger occurred on September 30, 2014. The unaudited pro forma condensed combined statements of income for the twelve months ended September 30, 2014 are presented assuming the merger and the related borrowings used to finance the merger occurred on October 1, 2013. 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 merger on the combined balance sheet and the combined income statements 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 merger is completed. Any excess of the purchase price over the fair value of identified assets acquired and liabilities assumed is recognized as goodwill. As of the issuance of this proxy statement/prospectus, the purchase price allocation adjustments are estimates and may be further refined as additional information becomes available post-merger.

The unaudited pro forma condensed combined financial information has been prepared by BD 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 merger 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 entity will experience after the merger, and therefore discontinued operations of both BD and CareFusion are not presented. As required, the unaudited pro forma condensed combined financial information includes adjustments which give effect to events that are directly attributable to the merger and are factually supportable; as such, any planned adjustments affecting the balance sheet, income statement, or shares of common stock outstanding subsequent to the merger 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 merger or the impact of any non-recurring activity and one-time transaction related costs.

The date of the merger agreement is October 5, 2014. For pro forma purposes only, the valuation of consideration transferred is based on, among other things, BD’s closing share price as of October 3, 2014 of $115.84 per share. The value of the consideration transferred for accounting purposes will ultimately be based on the closing share price of BD’s common stock on the last trading day prior to the closing date of the transaction, and could materially change. For pro forma purposes only, the fair value of CareFusion’s stock options to be converted is estimated based on BD’s closing share price as of October 3, 2014 of $115.84 per share. An increase of 25 percent in BD’s share price would increase the total consideration by approximately $587 million and a decrease of 25 percent in BD’s share price would decrease the total consideration by approximately $585 million. The total actual consideration will fluctuate until the closing of the acquisition of CareFusion.

The unaudited pro forma condensed combined financial information is derived from and should be read in conjunction with the historical consolidated financial statements of BD (which are available in BD’s Annual Report on Form 10-K for the fiscal year ended September 30, 2014) and the historical consolidated financial statements of CareFusion (which are found in CareFusion’s Annual Report on Form 10-K for the fiscal year ended June 30, 2014 and Quarterly Report for the three months ended September 30, 2014, which have been incorporated by reference in this proxy statement/prospectus).
