Exhibit 99.3

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION OF MYLAN

AND THE UPJOHN BUSINESS

On July 29, 2019, Pfizer and Newco entered into the Separation and Distribution Agreement and, on the same day, Pfizer, Newco, Mylan and certain of their affiliates entered into the Business Combination Agreement. These agreements provide for Pfizer to combine its Upjohn Business with Mylan in a Reverse Morris Trust transaction (the “Combination”). The Upjohn Business includes 20 primarily off-patent solid oral dose legacy brands, such as Lyrica, Lipitor, Celebrex and Viagra, as well as certain generic medicines. Pfizer and certain of Pfizer’s subsidiaries will engage in a series of transactions so that the Upjohn Business is held by Newco and its subsidiaries and is separated from the remainder of Pfizer’s businesses. We refer to these transactions as the “Separation.” In connection with the Separation and as partial consideration for the contribution of the Upjohn Business to Newco, Newco will make a cash payment of $12 billion to Pfizer (referred to as the “Cash Distribution”), and will issue to Pfizer additional shares of Newco common stock as part of Pfizer’s spin-off or split-off (referred to as the “Distribution”). When the Distribution and Combination are completed, Pfizer stockholders as of the record date of the Distribution will own 57% of the outstanding shares of Newco common stock, and Mylan shareholders as of immediately before the Combination will own 43% of the outstanding shares of Newco common stock, in each case on a fully diluted basis.

The unaudited pro forma condensed combined financial information reflects Pfizer’s intent that the Distribution will occur through a spin-off. In a spin-off, Pfizer will effect the Distribution by distributing on a pro rata basis all of the shares of Newco common stock then held by Pfizer to Pfizer stockholders entitled to shares of Newco common stock in the Distribution as of the record date of the Distribution. If Pfizer were to effect the Distribution through a split-off, Pfizer would offer its stockholders the option to exchange all or a portion of their shares of Pfizer common stock for shares of Newco common stock in an exchange offer, resulting in a reduction in shares of Pfizer common stock outstanding, with any shares of Newco common stock remaining after consummation of the exchange offer then distributed on a pro rata basis to Pfizer stockholders whose shares of Pfizer common stock remain outstanding after the consummation of the exchange offer. As such, there is no effect on purchase accounting between a spin-off and a split-off in accordance with ASC 805 Business Combinations (“ASC 805”) as the total number of shares of Newco common stock issued is not impacted by the form of the Distribution.

The unaudited pro forma condensed combined financial information has been prepared assuming the Combination will be effected through the Mylan Merger. However, even if the Alternative Transaction Structure is utilized to effect the Combination, there will be no impact on the total number of shares of Newco common stock issued to Pfizer stockholders. As such, Newco and Mylan do not expect there would be a material impact on purchase accounting in accordance with ASC 805 even if the Alternative Transaction Structure is utilized.

It is not expected that the Mylan Merger will be treated as involving a transfer on sale of U.K. shares for U.K. stamp duty purposes (and Mylan intends to apply for confirmation of this from HM Revenue & Customs), and the unaudited pro forma condensed combined financial information assumes no U.K. stamp duty would arise. The Alternative Transaction Structure is likely to involve a transfer on sale for U.K. stamp duty purposes and accordingly, if the Combination were to be effected by way of the Alternative Transaction Structure, U.K. stamp duty may arise at a rate of 0.5% on the relevant consideration (including the assumption of debt) attributable to the transfer of shares in any U.K. incorporated companies. At this time, Mylan does not have sufficient information available to make a preliminary estimate of any potential U.K. stamp duty liability.

Because the Cash Distribution is required as partial consideration for the contribution of the Upjohn Business to Newco, it is not considered part of the merger consideration for purchase accounting in accordance with ASC 805. Since a Reverse Morris Trust transaction is a stock for stock transaction, the merger consideration is made up of only the shares of Newco common stock issued to Pfizer stockholders.

The $12 billion of debt to be incurred by Newco and utilized for the Cash Distribution is not currently reflected in the historical combined financial statements of the Upjohn Business as Newco will incur borrowings

1

for the Cash Distribution on or prior to the date of the Cash Distribution, which will occur immediately prior to the closing of the Combination. As such, the Cash Distribution is included in the Financing Adjustments in Note 4 and excluded from the Preliminary Purchase Price calculation in Note 3 to the unaudited pro forma condensed combined financial information. The $12 billion is considered debt of Newco assumed in the Combination in accordance with ASC 805. The Exchange Ratio in the Business Combination Agreement will not be impacted by the Cash Distribution.

The following unaudited pro forma condensed combined financial information presents the combination of the historical financial statements of Mylan and the Upjohn Business adjusted to give effect to the Combination and related transactions, including borrowings under the Bridge Facility, and the distribution contemplated by the Business Combination Agreement and the Separation and Distribution Agreement.

The unaudited pro forma condensed combined statements of operations for the three months ended March 31, 2020 and for the year ended December 31, 2019 combine the historical unaudited condensed consolidated and the historical audited consolidated statements of operations of Mylan and the historical unaudited condensed combined and the historical audited combined statements of income for the Upjohn Business, respectively, giving effect to the Combination as if it had been consummated on January 1, 2019. The unaudited pro forma condensed combined balance sheet combines the historical unaudited condensed consolidated balance sheet of Mylan as of March 31, 2020 and the historical unaudited condensed combined balance sheet of the Upjohn Business as of March 29, 2020, giving effect to the Combination as if it had been consummated on March 31, 2020.

The unaudited pro forma condensed combined financial information was prepared in accordance with U.S. GAAP using the acquisition method of accounting in accordance with ASC 805, with Mylan considered the accounting acquirer of the Upjohn Business. See “The Transactions—Accounting Treatment” beginning on page 102 of this document for more information. Under the acquisition method of accounting, the purchase price is allocated to the underlying tangible and intangible assets acquired and liabilities assumed based on their respective fair market values with any excess purchase price allocated to goodwill. The unaudited pro forma condensed combined financial information is for informational purposes only and does not purport to indicate the results that would have actually been attained had the Combination been completed on the assumed date or for the periods presented, or which may be realized in the future. To produce the unaudited pro forma condensed combined financial information, Mylan allocated the purchase price of the Upjohn Business using its best estimates of fair value. These estimates are based on the most recently available information. To the extent there are significant changes to the operations or results of the Upjohn Business, the assumptions and estimates herein could change significantly. The allocation of the purchase price of the Upjohn Business is dependent upon certain valuation and other studies that are not yet final. Accordingly, the pro forma purchase price adjustments are preliminary and subject to further adjustments as additional information becomes available and as additional analyses are performed. Upon completion of the Combination, final valuations will be performed. There can be no assurances that these final valuations will not result in material changes to the purchase price allocation and related pro forma operating results. Furthermore, Newco could have reorganization and restructuring expenses as well as potential cost savings, operating synergies, or revenue enhancements as a result of combining Mylan and the Upjohn Business. The unaudited pro forma condensed combined financial information does not reflect these potential expenses, cost savings, operating synergies, or revenue enhancements or the costs necessary to achieve these cost savings, operating synergies, and revenue enhancements. The unaudited pro forma condensed combined financial information reflects only the pro forma adjustments that are factually supportable, directly attributable to the Combination and, with respect to the unaudited pro forma condensed combined statements of operations, expected to have a continuing impact on the combined results of Newco.

The Business Combination Agreement provides that Newco will pay Pfizer for certain losses arising out of certain third-party actions following the closing date. See “Business Combination Agreement—Certain Litigation Matters” for more information on the litigation matters for which Newco has agreed to pay Pfizer for a certain amount of losses. At March 31, 2020, Mylan has not estimated or accrued any amounts related to such

2

contingency. Any such amount will be considered additional purchase price in the form of contingent consideration. At this time, Mylan does not have sufficient information available to make a preliminary estimate of the fair value of any contingent consideration. The Exchange Ratio in the Business Combination Agreement will not be impacted by this provision.

The Upjohn Business’s historical combined financial statements have been derived from the consolidated financial statements and accounting records of Pfizer and include allocations for direct costs and indirect costs attributable to the operations of the Upjohn Business. These historical combined financial statements do not purport to reflect what the results of operations, comprehensive income, financial position, equity or cash flows would have been had the Upjohn Business operated as an independent standalone company during the periods presented.

The unaudited pro forma condensed combined financial information should be read in conjunction with the following materials:

Notes to Unaudited Pro Forma Condensed Combined Financial Information

1. General

The unaudited pro forma condensed combined financial information was prepared in accordance with U.S. GAAP using the acquisition method of accounting in accordance with ASC 805, Business Combinations, with Mylan considered to be the accounting acquirer of the Upjohn Business. The historical financial information has been adjusted to give effect to pro forma events that are: factually supportable; directly attributable to the Combination; and, with respect to the unaudited pro forma condensed combined statements of operations, expected to have a continuing impact on the results of Newco. As such, the impact from transaction-related expenses are not included in the unaudited pro forma condensed combined statements of operations. However, the impact of these expenses is reflected in the unaudited pro forma condensed combined balance sheet as a decrease to cash and cash equivalents with a corresponding decrease to retained earnings.

Assumptions and estimates underlying the pro forma adjustments are described in Notes 3 through 7. Since the unaudited pro forma condensed combined financial information has been prepared based on preliminary estimates, the final amounts recorded at the date of consummation of the Combination may differ materially from the information presented. These estimates are subject to change pending further review of the assets acquired and liabilities assumed and the final purchase price and its allocation thereof.

The unaudited pro forma condensed combined financial information has been presented for informational purposes only and does not purport to indicate the results that would have actually been attained had the Combination been completed on the assumed date or for the periods presented, or which may be realized in the future.

2. Basis of Presentation

The unaudited pro forma condensed combined financial information should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations of the Upjohn Business” and the historical combined financial statements of the Upjohn Business and the related notes thereto for the year ended December 31, 2019, that were previously filed with the SEC and are incorporated by reference into this document and for the three months ended March 29, 2020 which are included in this document, as well as the sections entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in Mylan’s Annual Report on Form 10-K, as amended, for the year ended December 31, 2019 and Mylan’s Quarterly Report on Form 10-Q for the period ended March 31, 2020, that were previously filed with the SEC and are incorporated by reference into this document, and the consolidated financial statements of Mylan and the related notes thereto covering these periods incorporated by reference into this document. See “Where You Can Find Additional Information” beginning on page ii of this document for more information.

The Combination has been accounted for using Mylan’s historical information and accounting policies and combining the assets and liabilities of the Upjohn Business at their respective estimated fair values. The assets and liabilities of the Upjohn Business have been measured at fair value based on various preliminary estimates using assumptions that Mylan’s management believes are reasonable utilizing information currently available. Use of different estimates and judgments could yield materially different results. The total estimated purchase price has been measured using the closing market price of Mylan ordinary shares as of June 5, 2020 (the latest practicable date prior to the date of this document). The final purchase price will be measured at the closing date of the Combination. This will result in a per share equity value that is different from that assumed for purposes of preparing the unaudited pro forma condensed combined financial information. The purchase price allocation is subject to finalization of Mylan’s analysis of the fair value of the assets and liabilities of the Upjohn Business as of the closing of the Combination. Differences from these preliminary estimates could be material.

The Upjohn Business’s historical combined financial statements have been derived from the consolidated financial statements and accounting records of Pfizer and include allocations for direct costs and indirect costs

7

attributable to the operations of the Upjohn Business. These historical combined financial statements do not purport to reflect what the results of operations, comprehensive income, financial position, equity or cash flows would have been had the Upjohn Business operated as an independent standalone company during the periods presented.

At this time Mylan does not have sufficient information available to make a reasonable preliminary estimate of the fair value adjustment for the Upjohn Business’s property, plant and equipment. Therefore, no adjustment has been recorded to modify the current book value for the respective items. The estimated fair value allocated to property, plant and equipment in the unaudited pro forma condensed combined balance sheet as of March 31, 2020 is based upon a preliminary assumption that the estimated fair value approximates the net book value. Changes in the estimated fair values are expected based on valuation studies and other analyses which have not been performed to date. This estimate is preliminary and subject to change and could vary materially from the actual adjustment on the consummation date.

Based on estimated useful lives averaging approximately 25 years for buildings, for each $100 million change in the total fair value adjustment there could be an annual change in depreciation expense of approximately $4 million.

Based on estimated useful lives averaging approximately 10 years for equipment, for each $30 million change in the total fair value adjustment there could be an annual change in depreciation expense of approximately $3 million.

Acquisition-related transaction costs, such as investment banker, advisory, legal, valuation, and other professional fees are not included as a component of consideration transferred but are expensed as incurred. Transaction costs incurred by Mylan totaled $20 million and $74 million for the three months ended March 31, 2020 and the year ended December 31, 2019, respectively. These costs are included in the results of operations and eliminated in the unaudited pro forma condensed combined statements of operations adjustments. Transaction costs are not included in the historical combined financial statements of the Upjohn Business and therefore no related elimination was necessary in preparing the unaudited pro forma condensed combined statements of operations. Additionally, the unaudited pro forma condensed combined balance sheet reflects approximately $220 million and $177 million of estimated additional acquisition-related transaction costs to be incurred by Mylan and on behalf of the Upjohn Business, respectively, as a reduction of cash with a corresponding decrease in retained earnings. No tax effect was recorded for these costs as their deductibility has not been assessed. These costs are not presented in the unaudited pro forma condensed combined statements of operations because they will not have a continuing impact on the consolidated results of Newco.

The unaudited pro forma condensed combined financial information does not reflect potential cost savings, operating synergies, or revenue enhancements that Newco may achieve as a result of the Combination or the costs to combine the operations of Mylan and the Upjohn Business or the costs necessary to achieve these cost savings, operating synergies, and revenue enhancements.

3. Preliminary Purchase Price

The preliminary estimate of fair value includes issuance of common stock to Pfizer stockholders in connection with the Combination. The number of shares of Newco common stock that will be issued will be such that, after the Combination, Pfizer stockholders as of the record date of the Distribution will hold 57% of the fully diluted outstanding shares of Newco common stock and former Mylan shareholders as of immediately before consummation of the Combination will hold 43% of the fully diluted outstanding shares of Newco common stock following the consummation of the Combination. Upon consummation of the Combination, Pfizer stockholders will receive approximately 692.9 million shares of Newco common stock.

The $12 billion of debt to be incurred by Newco and utilized for the Cash Distribution is not currently reflected in the historical combined financial statements of the Upjohn Business as Newco will incur borrowings for the Cash Distribution on or prior to the date of the Cash Distribution, which will occur immediately prior to the closing of the Combination. As such, the Cash Distribution is included in the Financing Adjustments in Note 4 and excluded from the Preliminary Purchase Price calculation in this Note 3 to the unaudited pro forma condensed combined financial information. The $12 billion is considered debt of Newco assumed in the Combination in accordance with ASC 805. The Exchange Ratio in the Business Combination Agreement will not be impacted by the Cash Distribution.

The Business Combination Agreement provides that Newco will pay Pfizer for certain losses arising out of certain third-party actions following the closing date. See “Business Combination Agreement—Certain Litigation Matters” for more information on the litigation matters for which Newco has agreed to pay Pfizer for a certain amount of losses. At March 31, 2020, Mylan has not estimated or accrued any amounts related to such contingency. Any such amount will be considered additional purchase price in the form of contingent consideration. At this time, Mylan does not have sufficient information available to make a preliminary estimate of the fair value of any contingent consideration. The Exchange Ratio in the Business Combination Agreement will not be impacted by this provision.

The table below depicts a sensitivity analysis of the estimated purchase consideration and goodwill, assuming a 10% increase or decrease of the Mylan ordinary share closing price used to determine the total estimated purchase consideration. For purposes of this calculation, the total number of shares of Newco common stock to be issued has been assumed to be the same as in the table above.

4. Financing Adjustments

On July 29, 2019, Newco and certain financial institutions executed a 364-day bridge commitment letter (the “Commitment Letter”) pursuant to which such financial institutions have committed to provide bridge financing (the “Bridge Facility”) to Newco to fund in part the amount of the Cash Distribution and to pay fees

9

and expenses related to the transactions contemplated by the Business Combination Agreement. Mylan N.V. (or its successor), Mylan Inc. and each other guarantor or obligor under any of Mylan’s existing debt securities and credit facilities with a principal amount of at least $500 million will be guarantors of the Bridge Facility from and after the consummation of the Combination.

Newco expects to use the net proceeds from alternative sources of permanent financing to fund the Cash Distribution; however, to the extent that the amount is not funded from such sources, Newco currently intends to fund any shortfall with borrowings under the Bridge Facility. Because the permanent financing has not yet been obtained, we have assumed the Cash Distribution will be funded in full using the Bridge Facility. The unaudited pro forma condensed combined balance sheet is adjusted to reflect borrowings of $12.0 billion under the Bridge Facility, which is classified as current in the unaudited pro forma condensed combined balance sheet. Any borrowing under the Bridge Facility is subject to availability and the terms and conditions set forth in the Commitment Letter, which Newco previously filed with the SEC.

For purposes of the unaudited pro forma condensed combined statements of operations, we have assumed that the amounts outstanding under the Bridge Facility bear interest at LIBOR, plus an applicable margin ranging from 138 – 213 basis points, depending upon the duration of amounts outstanding and Newco’s credit rating. The pro forma adjustment to interest expense in the condensed combined statements of operations is approximately $121 million for the three months ended March 31, 2020 and $505 million for the year ended December 31, 2019.

It is assumed that Newco will incur approximately $420 million of debt issuance costs for the Bridge Facility, primarily consisting of financing, commitment and duration fees. These debt issuance costs are recorded as a current liability in the unaudited pro forma condensed combined balance sheet as of March 31, 2020. Since the Bridge Facility has a maturity of less than one year, there is no adjustment to the pro forma condensed combined statements of operations for these debt issuance costs as there is no continuing impact. The fees Newco will ultimately pay, and the level of net debt ultimately incurred, could vary significantly from what is assumed in this unaudited pro forma condensed combined financial information. Variances could arise from multiple factors including: the amount of cash on hand at the time of the closing, actual timing and amount of borrowings and repayments under the Bridge Facility, the actual mix of permanent debt financing, the actual fixed / floating mix of permanent debt financing and Newco’s credit rating. Accordingly, the estimated debt and interest expense reflected in this unaudited pro forma condensed combined financial information may change and the change could be significant. A change of 125 basis points to the interest rate could result in an increase or decrease in the pro forma interest expense of approximately $38 million for the three months ended March 31, 2020 and approximately $150 million for the year ended December 31, 2019.

5. Pro Forma Reclassification Adjustments

Certain reclassifications have been recorded to the Upjohn Business’s historical combined financial information to conform to Mylan’s presentation, as follows:

Balance Sheet Reclassifications

Statements of Operations Reclassifications

13

Following the consummation of the Combination, Mylan will conduct a review of the Upjohn Business’s accounting policies in an effort to determine if differences in accounting policies require adjustment or reclassification of the Upjohn Business’s results of operations or reclassification of assets or liabilities to conform to Mylan’s accounting policies and classifications. As a result of that review, Mylan may identify differences between the accounting policies that, when conformed, could have a material impact on this unaudited pro forma condensed combined financial information. During the preparation of this unaudited pro forma condensed combined financial information, Mylan was not aware of any material differences between accounting policies, except for certain reclassifications necessary to conform to Mylan’s financial presentation, and accordingly, this unaudited pro forma condensed combined financial information does not assume any material differences in accounting policies between Mylan and the Upjohn Business.

6. Unaudited Pro Forma Condensed Combined Balance Sheet Adjustments

Adjustments included in the accompanying unaudited pro forma condensed combined balance sheet as of March 31, 2020 are represented by the following:

14

On May 29, 2020, the parties entered certain amendments to the Separation and Distribution Agreement and the Business Combination Agreement, which included cash balances being shared. Potential adjustments related to target cash balances, working capital adjustments and cost sharing items cannot be reasonably estimated at this time.

Tax related balances remaining with Pfizer primarily consists of noncurrent net tax liabilities associated with the U.S. Tax Cuts and Jobs Act repatriation tax on accumulated post-1986 foreign earnings and taxes for periods prior to the Combination date.

The fair value estimate of identifiable intangible assets is preliminary and is determined using the “income approach,” which is a valuation technique that calculates an estimate of the fair value of an asset based on market participant expectations of the cash flows an asset would generate over its remaining useful life. Some of the more significant assumptions inherent in the development of the identifiable intangible assets valuations, from the perspective of a market participant, include the estimated amount and timing of projected net cash flows for each year for each product (including net revenues, cost of sales, research and development costs, selling and marketing costs and working capital), the appropriate discount rate to select in order to measure the risk inherent in each future cash flow stream, the assessment of each asset’s life cycle, competitive trends or regulatory forces impacting the asset and each cash flow stream as well as other factors. No assurances can be given that the underlying assumptions used to prepare the discounted cash flow analysis will not change. For these and other reasons, actual results may vary significantly from estimated results.

7. Unaudited Pro Forma Condensed Combined Statements of Operations Adjustments

Adjustments included in the accompanying unaudited pro forma condensed combined statements of operations are represented by the following:

The estimated weighted-average useful life of the product rights to be acquired is 18 years. A five percent (5%) increase or decrease in the fair value of the product rights would increase or decrease amortization by approximately $14 million for the three months ended March 31, 2020 and approximately $56 million for the year ended December 31, 2019.

8. Comparative Per Share Information

The following table sets forth selected historical share information of Mylan and unaudited pro forma share information after giving effect to the Combination. Per share information for the Upjohn Business is not presented because the Upjohn Business did not have outstanding capital stock since its historical combined financial statements have been prepared on a carve-out basis.
