Acquisition, Divestitures, Licensing Arrangements, Collaborative Arrangements and Privately Held Investment	Acquisition, Divestitures, Licensing Arrangements, Collaborative Arrangements and Privately Held Investment A. Acquisition AstraZeneca’s Small Molecule Anti-Infectives Business (EH) On December 22, 2016, which fell in the first fiscal quarter of 2017 for our international operations, we acquired the development and commercialization rights to AstraZeneca’s small molecule anti-infectives business, primarily outside the U.S., including the commercialization and development rights to the approved EU drug Zavicefta™ (ceftazidime-avibactam), the marketed agents Merrem™/Meronem™ (meropenem) and Zinforo™ (ceftaroline fosamil), and the clinical development assets ATM-AVI and CXL (ceftaroline fosamil-AVI). In 2017, under the terms of the agreement, we made payments of approximately $605 million to AstraZeneca related to the transaction. We made an additional milestone payment of $125 million in our first fiscal quarter of 2018 and we will make a deferred payment of $175 million to AstraZeneca in January 2019. In addition, we may be required to pay an additional milestone payment of $75 million if the related milestone is achieved prior to December 31, 2021, and up to $600 million if sales of Zavicefta™ exceed certain thresholds prior to January 1, 2026, as well as tiered royalties on sales of Zavicefta™ and ATM-AVI in certain markets for a period ending on the later of 10 years from first commercial sale or the loss of patent protection or loss of regulatory exclusivity. The total royalty payments are unlimited during the royalty term and the undiscounted payments are expected to be in the range of approximately $292 million to $512 million. The total fair value of consideration transferred for AstraZeneca’s small molecule anti-infectives business was approximately $1,040 million inclusive of cash paid and the fair value of contingent consideration. In connection with this acquisition, we recorded $894 million in Identifiable intangible assets, consisting of $728 million in Developed technology rights and $166 million in IPR&D. We also recorded $92 million in Other current assets related to the economic value of inventory which was retained by AstraZeneca for sale on our behalf, $73 million in Goodwill and $19 million of net deferred tax liabilities. The final allocation of the consideration transferred to the assets acquired and the liabilities assumed has been completed. B. Divestitures Sale of Hospira Infusion Systems Net Assets to ICU Medical, Inc. (EH) On October 6, 2016, we announced that we entered into a definitive agreement under which ICU Medical agreed to acquire all of our global infusion systems net assets, HIS, for approximately $1 billion in cash and ICU Medical common stock. HIS includes IV pumps, solutions, and devices. As a result of the performance of HIS relative to ICU Medical’s expectations, on January 5, 2017, we entered into a revised agreement with ICU Medical under which ICU Medical would acquire HIS for up to approximately $900 million, composed of cash and contingent cash consideration, ICU Medical common stock and seller financing. The revised transaction closed on February 3, 2017. At closing, we received 3.2 million newly issued shares of ICU Medical common stock (as originally agreed), which we initially valued at approximately $428 million (based upon the closing price of ICU Medical common stock on the closing date less a discount for lack of marketability) and which are reported as equity securities at fair value in Long-term investments on the condensed consolidated balance sheet. In August 2018, we sold 700,000 shares of ICU Medical common stock for which we recognized a gain during the period of $50 million, reflecting the increase in fair value of the equity investment since the beginning of the year, most of which was previously recognized as 2018 unrealized gains. In addition, we continue to hold 2.5 million shares of ICU Medical common stock and we recognized unrealized gains of $24 million in the third quarter of 2018 and unrealized gains of $229 million in the first nine months of 2018 related to these remaining shares. We also received a promissory note in the amount of $75 million, which was repaid in full as of December 31, 2017, and net cash of approximately $200 million before customary adjustments for net working capital, which is reported in Other investing activities, net on the condensed consolidated statement of cash flows for the nine months ended October 1, 2017. In addition, we are entitled to receive a contingent amount of up to an additional $225 million in cash based on ICU Medical’s achievement of certain cumulative performance targets for the combined company through December 31, 2019. After our recent sale of ICU Medical shares, we own approximately 12% of ICU Medical. We recognized pre-tax income of $2 million in the third quarter of 2018 and pre-tax income of $1 million in the first nine months of 2018, and we recognized pre-tax income of $12 million in the third quarter of 2017 and pre-tax losses of $52 million in the first nine months of 2017 in Other (income)/deductions––net, representing adjustments to amounts previously recorded in 2016 to write down the HIS net assets to fair value less costs to sell. For additional information, see Note 4 and Notes to Consolidated Financial Statements––Note 2. Acquisitions, Sale of Hospira Infusion Systems Net Assets, Research and Development and Collaborative Arrangements, Equity-Method Investments and Cost-Method Investment in Pfizer’s 2017 Financial Report. While we have received the full purchase price excluding the contingent amount as of the February 3, 2017 closing, the sale of the HIS net assets was not fully completed in certain non-U.S. jurisdictions as of the third quarter of 2018 due to temporary regulatory or operational constraints. In these jurisdictions, which represent a relatively small portion of the HIS net assets, we continued to operate the net assets for the net economic benefit of ICU Medical, and we were indemnified by ICU Medical against risks associated with such operations during the interim period, subject to our obligations under the definitive transaction agreements. We have previously treated these jurisdictions as sold for accounting purposes. In connection with the sale transaction, we entered into certain transitional agreements designed to facilitate the orderly transition of the HIS net assets to ICU Medical. These agreements primarily relate to administrative services, which are generally to be provided for a period of up to 24 months after the closing date. We will also manufacture and supply certain HIS products for ICU Medical and ICU Medical will manufacture and supply certain retained Pfizer products for us after closing, generally for a term of five years. These agreements are not material to Pfizer and none confers upon us the ability to influence the operating and/or financial policies of ICU Medical subsequent to the sale. Contribution Agreement Between Pfizer and Allogene Therapeutics, Inc. (WRD) In April 2018, Pfizer and Allogene announced that the two companies entered into a contribution agreement for Pfizer’s portfolio of assets related to allogeneic CAR T therapy, an investigational immune cell therapy approach to treating cancer. Under this agreement, Allogene received from Pfizer rights to pre-clinical and clinical CAR T assets, all of which were previously licensed to Pfizer from French cell therapy company, Cellectis, beginning in 2014 and French pharmaceutical company, Servier, beginning in 2015. Allogene assumed responsibility for all potential financial obligations to both Cellectis and Servier. Pfizer will continue to participate financially in the development of the CAR T portfolio through an ownership stake in Allogene. Separately, Pfizer continues to maintain its approximate 7% ownership stake in Cellectis that was obtained in 2014 as part of the licensing agreement in which Pfizer obtained exclusive rights to pursue the development and commercialization of certain Cellectis CAR T therapies in exchange for an upfront payment of $80 million, as well as potential future development, regulatory and commercial milestone payments and royalties. In connection with the Allogene transaction, Pfizer recognized a non-cash $50 million pre-tax gain in Other (income)/deductions––net in the second quarter of 2018, representing the difference between the $127 million fair value of the equity investment received and the book value of assets transferred (including an allocation of goodwill) (see Note 4). In October 2018, Allogene consummated an initial public offering of new shares of its common stock, which resulted in Pfizer’s preferred stock converting into common stock and a decrease in our ownership percentage from approximately 25% to approximately 19%. The closing price on the day of the initial public offering was $25 per share. Beginning as of the date of the initial public offering, our investment in Allogene, which is reported at $127 million in Long-term investments on the condensed consolidated balance sheet as of September 30, 2018, will be measured at fair value with changes in fair value recognized in net income. Sale of Phase 2b Ready AMPA Receptor Potentiator for CIAS to Biogen Inc. (WRD) In April 2018, we sold our Phase 2b ready AMPA receptor potentiator for CIAS to Biogen. We received $75 million upfront and have the opportunity to receive up to $515 million in future development and commercialization milestones, as well as tiered royalties in the low-to-mid-teen percentages. We recognized $75 million in Other (income)/deductions––net in the second quarter of 2018 (see Note 4). We will record the milestones and royalties to Other (income)/deductions––net when due, or earlier if we have sufficient experience to determine such amounts are not probable of significant reversal. Divestiture of Neuroscience Assets (WRD) In September 2018, we and Bain Capital entered into a transaction to create a new biopharmaceutical company, Cerevel, to continue development of a portfolio of clinical and preclinical stage neuroscience assets primarily targeting disorders of the central nervous system including Parkinson’s disease, epilepsy, Alzheimer’s disease, schizophrenia and addiction. These assets were part of the neuroscience discovery and early development efforts, which we announced we were ending in January 2018. In connection with this transaction, we out-licensed the portfolio to Cerevel in exchange for a 25% ownership stake in Cerevel’s parent company, Cerevel Therapeutics, Inc., and potential future regulatory and commercial milestone payments and royalties. Bain Capital has committed to invest $350 million to develop the portfolio, with the potential for additional funding as the assets advance. In connection with the transaction, we recognized a non-cash $343 million pre-tax gain in Other (income)/deductions––net, representing the fair value of the equity investment received as the assets transferred had a book value of $0 (see Note 4). Our investment in Cerevel Therapeutics, Inc. is reported in Long-term investments on the consolidated balance sheet as of September 30, 2018. C. Licensing Arrangements Shire International GmbH (IH) In 2016, we out-licensed PF-00547659, an investigational biologic being evaluated for the treatment of moderate-to-severe inflammatory bowel disease, including ulcerative colitis and Crohn’s disease, to Shire for an upfront payment of $90 million, up to $460 million in development and sales-based milestone payments and potential future royalty payments on commercialized products. The $90 million upfront payment was initially deferred and recognized in Other (income)/deductions––net ratably through December 2017. In the first quarter of 2018, we recognized $75 million in Other (income)/deductions––net for a milestone payment received from Shire related to their first dosing of a patient in a Phase 3 clinical trial of the compound for the treatment of ulcerative colitis, and in the third quarter of 2018, we recognized $35 million in Other (income)/deductions––net for a milestone payment received from Shire related to their first dosing of a patient in a Phase 3 clinical trial of the compound for the treatment of Crohn’s disease (see Note 4). BionTech AG (WRD) In August 2018, a multi-year R&D arrangement went into effect between BionTech AG (BionTech), a privately held company, and Pfizer to develop mRNA-based vaccines for prevention of influenza (flu). In September 2018, we made an upfront payment of $50 million to BionTech, which was recorded in Research and development expenses, and BionTech is eligible to receive up to an additional $325 million in future development and sales based milestones and future royalty payments associated with worldwide sales. As part of the transaction, we also purchased 169,670 newly-issued ordinary shares of BionTech for $50 million in the third quarter of 2018, which are reported in Long-term investments in the condensed consolidated balance sheet as of September 30, 2018. D. Collaboration Arrangements Collaboration with Merck & Co., Inc. (IH) Under a worldwide collaboration agreement, except for Japan, we collaborated with Merck on the clinical development of ertugliflozin and ertugliflozin-containing fixed-dose combinations with metformin and Januvia (sitagliptin) tablets, which were approved by the FDA in December 2017 and the European Commission in March 2018 as Steglatro, Segluromet and Steglujan. Merck will exclusively promote Steglatro and the two fixed-dose combination products and we will share revenues and certain costs with Merck on a 60%/40% basis, with Pfizer having the 40% share. Pfizer records its share of the collaboration revenues as product sales as we supply the ertugliflozin active pharmaceutical ingredient to Merck for use in the alliance products. In the first quarter of 2017, we received a $90 million milestone payment from Merck upon the FDA’s acceptance for review of the NDAs for ertugliflozin and two fixed-dose combinations (ertugliflozin plus Januvia (sitagliptin) and ertugliflozin plus metformin), which, as of December 31, 2017, was deferred and primarily reported in Other noncurrent liabilities, and through December 31, 2017, was being recognized in Other (income)/deductions––net over a multi-year period. As of December 31, 2017, we were due a $60 million milestone payment from Merck, which we received in the first quarter of 2018, in conjunction with the approval of ertugliflozin by the FDA. As of December 31, 2017, the $60 million due from Merck was deferred and primarily reported in Other noncurrent liabilities. In the first quarter of 2018, in connection with the approval of ertugliflozin in the EU, we recognized a $40 million milestone payment from Merck in Other (income)/deductions––net (see Note 4). We are eligible for additional payments associated with the achievement of future commercial milestones. In the first quarter of 2018, in connection with the adoption of a new accounting standard, as of January 1, 2018, the $60 million of deferred income and approximately $85 million of the $90 million of deferred income associated with the above-mentioned milestone payments were recorded to and included in the $584 million cumulative effect adjustment to Retained earnings. See Note 1B for additional information. Collaboration with Eli Lilly & Company (IH) In 2013, we entered into a collaboration agreement with Lilly to jointly develop and globally commercialize Pfizer’s tanezumab, which provides that Pfizer and Lilly will equally share product-development expenses as well as potential revenues and certain product-related costs. We received a $200 million upfront payment from Lilly in accordance with the collaboration agreement between Pfizer and Lilly, which was deferred and primarily reported in Other noncurrent liabilities, and through December 31, 2017, was being recognized in Other (income)/deductions––net over a multi-year period beginning in the second quarter of 2015. Pfizer and Lilly resumed the Phase 3 chronic pain program for tanezumab in July 2015. The FDA granted Fast Track designation for tanezumab for the treatment of chronic pain in patients with osteoarthritis and chronic low back pain in June 2017. Under the collaboration agreement with Lilly, we are eligible to receive additional payments from Lilly upon the achievement of specified regulatory and commercial milestones. In the first quarter of 2018, in connection with the adoption of a new accounting standard, as of January 1, 2018, approximately $107 million of deferred income associated with the above-mentioned upfront payment was recorded to and included in the $584 million cumulative effect adjustment to Retained earnings. See Note 1B for additional information. Approximately $33 million of the upfront payment continues to be deferred, of which approximately $24 million is reported in Other current liabilities and approximately $9 million is reported in Other noncurrent liabilities as of September 30, 2018. This amount is expected to be recognized in Other (income)/deductions––net over the remaining development period for the product between 2018 and 2020. E. Privately Held Investment AM-Pharma B.V. (WRD) In April 2015, we acquired a minority equity interest in AM-Pharma B.V., a privately-held Dutch biopharmaceutical company focused on the development of human recombinant Alkaline Phosphatase (recAP) for inflammatory diseases, and secured an exclusive option to acquire the remaining equity in the company. The option became exercisable after completion of a Phase 2 trial of recAP for the treatment of Acute Kidney Injury related to sepsis in the first quarter of 2018. We declined to exercise the option and the option expired unexercised during the second quarter of 2018.

In April 2015, we acquired a minority equity interest in AM-Pharma B.V., a privately-held Dutch biopharmaceutical company focused on the development of human recombinant Alkaline Phosphatase (recAP) for inflammatory diseases, and secured an exclusive option to acquire the remaining equity in the company. The option became exercisable after completion of a Phase 2 trial of recAP for the treatment of Acute Kidney Injury related to sepsis in the first quarter of 2018. We declined to exercise the option and the option expired unexercised during the second quarter of 2018.
