Note 1. Basis of Presentation and Significant Accounting Policies

A. Basis of Presentation

We prepared these condensed consolidated financial statements in conformity with U.S. GAAP, consistent in all material respects with those applied in our 2020 Form 10-K, except as disclosed in Note 1C. As permitted under the SEC requirements for interim reporting, certain footnotes or other financial information have been condensed or omitted.

These financial statements include all normal and recurring adjustments that are considered necessary for the fair statement of results for the interim periods presented. The information included in this Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our 2020 Form 10-K. Revenues, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be representative of those for the full year.

Pfizer’s fiscal quarter-end for subsidiaries operating outside the U.S. is as of and for the three and nine months ended August 29, 2021 and August 23, 2020, and for U.S. subsidiaries is as of and for the three and nine months ended October 3, 2021 and September 27, 2020.

Business development activities impacted financial results in the periods presented. See Note 1A in our 2020 Form 10-K, and Note 2. On November 16, 2020, we completed the spin-off and the combination of our Upjohn Business with Mylan to form Viatris. For additional information, see Note 2B in our 2020 Form 10-K. On December 21, 2020, which fell in Pfizer’s international first quarter of 2021, Pfizer and Viatris completed the termination of the Mylan-Japan collaboration pursuant to an agreement dated November 13, 2020, and we transferred related inventories and operations that were part of the Mylan-Japan collaboration to Viatris. As a result, the financial position and results of operations of the Upjohn Business and the Mylan-Japan collaboration are presented as discontinued operations. Prior-period information has been restated to reflect our current organization structure.

B. New Accounting Standard Adopted in 2021

On January 1, 2021, we adopted a new accounting standard for income tax that eliminates certain exceptions to the guidance related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The adoption of this guidance did not have a material impact on our condensed consolidated financial statements.

For information on new accounting standards adopted in 2020, see Note 1B in our 2020 Form 10-K.

C. Change in Accounting Principle

In the first quarter of 2021, we adopted a change in accounting principle to a more preferable policy under U.S. GAAP to immediately recognize actuarial gains and losses arising from the remeasurement of our pension and postretirement plans (MTM Accounting). Under the prior policy, we deferred recognition of these gains and losses in Accumulated other comprehensive loss. The accumulated actuarial gains/losses outside of a “corridor” were then amortized into net periodic benefit costs over the average remaining service period or the average life expectancy of participants. This change has been applied to all pension and postretirement plans on a retrospective basis for all prior periods presented, and as of January 1, 2020, resulted in a cumulative effect decrease to Retained earnings of $6.3 billion, with a corresponding offset to Accumulated other comprehensive loss. Each time a pension or postretirement plan is remeasured, the actuarial gain or loss is recognized immediately and classified as Other (income)/deductions––net.

We believe that MTM Accounting is a more preferable policy as it provides improved transparency of results and performance, better alignment with fair value accounting principles and a better reflection of current economic and interest rate trends on plan investments and assumptions and the actuarial impact of plan remeasurements.

D. Revenues and Trade Accounts Receivable

Customers––Our prescription pharmaceutical products are sold principally to wholesalers, but we also sell directly to retailers, hospitals, clinics, government agencies and pharmacies. In the U.S., we primarily sell our vaccine products directly to the federal government, CDC, wholesalers, individual provider offices, retail pharmacies and integrated delivery networks. Outside the U.S., we primarily sell our vaccines to government and non-government institutions.

Deductions from Revenues––Our accruals for Medicare, Medicaid and related state program and performance-based contract rebates, chargebacks, sales allowances and sales returns and cash discounts are as follows:

(MILLIONS)	October 3, 2021		December 31, 2020
Reserve against Trade accounts receivable, less allowance for doubtful accounts	$	996	$	861
Other current liabilities:
Accrued rebates	3,470		3,017
Other accruals	470		436
Other noncurrent liabilities	503		399
Total accrued rebates and other sales-related accruals	$	5,439	$	4,712

Trade Accounts Receivable––Trade accounts receivable are stated at their net realizable value. The allowance for credit losses reflects our best estimate of expected credit losses of the receivables portfolio determined on the basis of historical experience, current information, and forecasts of future economic conditions. In developing the estimate for expected credit losses, trade accounts receivables are segmented into pools of assets depending on market (U.S. versus international), delinquency status, and customer type (high risk versus low risk and government versus non-government), and fixed reserve percentages are established for each pool of trade accounts receivables.

In determining the reserve percentages for each pool of trade accounts receivables, we considered our historical experience with certain customers and customer types, regulatory and legal environments, country and political risk, and other relevant current and future forecasted macroeconomic factors. These credit risk indicators are monitored on a quarterly basis to determine whether there have been any changes in the economic environment that would indicate the established reserve percentages should be adjusted, and are considered on a regional basis to reflect more geographic-specific metrics. Additionally, write-offs and recoveries of customer receivables are tracked against collections on a quarterly basis to determine whether the reserve percentages remain appropriate. When management becomes aware of certain customer-specific factors that impact credit risk,

specific allowances for these known troubled accounts are recorded. Trade accounts receivable are written off after all reasonable means to collect the full amount (including litigation, where appropriate) have been exhausted.

During the three and nine months ended October 3, 2021 and September 27, 2020, additions to the allowance for credit losses, write-offs and recoveries of customer receivables were not material to our condensed consolidated financial statements. For additional information on our trade accounts receivable, see Note 1G in our 2020 Form 10-K.

Note 2. Discontinued Operations, Equity-Method Investment and Collaborative Arrangement

A. Discontinued Operations

Upjohn Separation and Combination with Mylan

On November 16, 2020, we completed the spin-off and the combination of the Upjohn Business with Mylan to form Viatris. See Note 1A.

In connection with this transaction, Pfizer and Viatris entered into various agreements to effect the separation and combination to provide a framework for our relationship after the combination, including a separation and distribution agreement, interim operating models, including agency arrangements, manufacturing and supply agreements (MSAs), transition service agreements (TSAs), a tax matters agreement, and an employee matters agreement, among others. The interim agency operating model arrangements primarily include billings, collections and remittance of rebates that we are performing on a transitional basis on behalf of Viatris. Under the MSAs, Pfizer or Viatris, as the case may be, manufactures, labels and packages products for the other party. In the three and nine months ended October 3, 2021, the amounts recorded under the above agreements were not material to our consolidated results of operations. Net amounts due from Viatris under the above agreements were approximately $197 million as of October 3, 2021 and $401 million as of December 31, 2020. The cash flows associated with the above agreements are included in Net cash provided by operating activities from continuing operations, except for a $277 million payment to Viatris made in the first quarter of 2021 pursuant to terms of the separation agreement, which is reported in Other financing activities, net, and was recorded as a payable to Viatris in Other current liabilities as of December 31, 2020. In addition, Pfizer and Mylan had pre-existing arms-length commercial agreements, which are continuing with Viatris and are not material to Pfizer’s consolidated financial statements.

The operating results of the Upjohn Business and the Mylan-Japan collaboration are reported as Income/(loss) from discontinued operations––net of tax.

Components of Income/(loss) from discontinued operations––net of tax:

(a)In the third quarter of 2021, Income/(loss) from discontinued operations—net of tax reflects post-closing adjustments directly related to our discontinued operations, including adjustments for legal and tax related matters. In the first nine months of 2021, Income/(loss) from discontinued operations—net of tax includes the operations of the Mylan-Japan collaboration, which terminated during Pfizer’s international first quarter of 2021, and post-closing adjustments directly related to our discontinued operations, including adjustments for tax, benefits and legal related matters. In the three and nine months ended September 27, 2020, Income/(loss) from discontinued operations—net of tax relates to the Upjohn Business and the Mylan-Japan collaboration and includes the change in accounting principle in the first quarter of 2021 to MTM Accounting, which has been applied on a retrospective basis for all prior periods presented. See Note 1C. In the three and nine months ended September 27, 2020, Income/(loss) from discontinued operations—net of tax includes interest expense of $76 million associated with the U.S. dollar and Euro denominated senior unsecured notes issued by Upjohn Inc. and Upjohn Finance B.V. in the second quarter of 2020 and charges of $144 million related to the remeasurement of Euro debt issued by Upjohn Finance B.V. in the second quarter of 2020.

B. Equity-Method Investment

Formation of Consumer Healthcare JV

On July 31, 2019, we completed a transaction in which we and GSK combined our respective consumer healthcare businesses into a new JV that operates globally under the GSK Consumer Healthcare name. In exchange, we received a 32% equity stake in the new company and GSK owns the remaining 68%.

We are accounting for our interest in the Consumer Healthcare JV as an equity-method investment. The carrying value of our investment in the Consumer Healthcare JV is $16.1 billion as of October 3, 2021 and $16.7 billion as of December 31, 2020 and is reported as a private equity investment in Equity-method investments as of October 3, 2021 and December 31, 2020. The Consumer Healthcare JV is a foreign investee whose reporting currency is the U.K. pound, and therefore we translate its financial statements into U.S. dollars and recognize the impact of foreign currency translation adjustments in the carrying value of our investment and in other comprehensive income. The decrease in the value of our investment from December 31, 2020 is primarily due to $549 million in pre-tax foreign currency translation adjustments (see Note 6), as well as dividends totaling approximately $295 million, partially offset by our share of the JV’s earnings. We record our share of earnings from the Consumer Healthcare JV on a quarterly basis on a one-quarter lag in Other (income)/deductions––net. Our total share of the JV’s earnings generated in the second quarter of 2021, which we recorded in our operating results in the third quarter of 2021, was $106 million. Our total share of the JV’s earnings generated in the fourth quarter of 2020 and first six months of 2021, which we recorded in our operating results in the first nine months of 2021, was $324 million. Our total share of the JV’s earnings generated in the second quarter of 2020, which we recorded in our operating results in the third quarter of 2020, was $166 million. Our total share of the JV’s earnings generated in the fourth quarter of 2019 and first six months of 2020, which we recorded in our operating results in the first nine months of 2020, was $306 million. The total amortization and adjustment of basis differences resulting from the excess of the initial fair value of our investment over the underlying equity in the carrying value of the net assets of the JV is included in Other (income)/deductions––net and was not material to our results of operations in the periods presented. See Note 4.

Summarized financial information for our equity method investee, the Consumer Healthcare JV, for the three and nine months ending June 30, 2021, the most recent period available, and for the three and nine months ending June 30, 2020, is as follows:
	Three Months Ended				Nine Months Ended

Net income	348		524		1,064		995
Income attributable to shareholders	330		518		1,012		959

C. Collaboration Arrangement

Collaboration with Arvinas

On July 22, 2021, we announced a global collaboration with Arvinas to develop and commercialize ARV-471, an investigational oral PROTAC® (PROteolysis TArgeting Chimera) estrogen receptor protein degrader. The estrogen receptor is a well-known disease driver in most breast cancers. Under the terms of the collaboration agreement, we made an upfront payment to Arvinas of $650 million in July 2021, which was recorded to Research and development expenses. On September 13, 2021, we made a $350 million equity investment in Arvinas, receiving approximately 3.5 million newly issued shares of Arvinas common stock, priced at a 30% premium to the 30-day volume weighted average price on July 20, 2021, representing an equity ownership stake by Pfizer of approximately 7% as of September 13, 2021. Arvinas is also eligible to receive up to $400 million in approval milestones and up to $1 billion in commercial milestones. The companies will equally share worldwide development costs, commercialization expenses and profits.

Note 3. Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiatives

A. Transforming to a More Focused Company Program

With the formation of the Consumer Healthcare JV in 2019 and the spin-off of our Upjohn Business in the fourth quarter of 2020, Pfizer has transformed into a focused, global leader in science-based innovative medicines and vaccines. We have

15

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

undertaken efforts to ensure our cost base and support model align appropriately with our new operating structure. While certain direct costs transferred to the Consumer Healthcare JV and to the Upjohn Business in connection with the spin-off, there are indirect costs which did not transfer. This program is primarily composed of the following three initiatives:

•We are taking steps to restructure our corporate enabling functions to appropriately support our business, R&D and PGS platform functions. We expect costs, primarily related to restructuring our corporate enabling functions, to total $1.6 billion, with substantially all costs to be cash expenditures. Actions include, among others, changes in location of certain activities, expanded use and co-location of centers of excellence and shared services, and increased use of digital technologies. The associated actions and the specific costs will primarily include severance and benefit plan impacts, exit costs as well as associated implementation costs.

•In addition, we are transforming our commercial go-to market model in the way we engage patients and physicians. We expect costs of $1.1 billion, with substantially all costs to be cash expenditures. Actions include, among others, centralization of certain activities and enhanced use of digital technologies. The costs for this effort primarily include severance and associated implementation costs.

•We are also optimizing our manufacturing network and incurring certain legacy cost-reduction initiatives related to our manufacturing business. We expect to incur costs of $500 million, with approximately 20% of the costs to be non-cash. The costs for this effort include, among other things, implementation costs, product transfer costs, site exit costs, as well as accelerated depreciation.

The program costs discussed above are expected to be incurred primarily from 2020 through 2022, and may be rounded and represent approximations.

From the start of this program in the fourth quarter of 2019 through October 3, 2021, we incurred costs of $2.0 billion.

Note 5. Tax Matters

A. Taxes on Income from Continuing Operations

Our effective tax rate for continuing operations was (4.2)% for the third quarter of 2021, compared to (60.9)% for the third quarter of 2020, and was 7.5% for the first nine months of 2021, compared to 6.7% for the first nine months of 2020.

The negative effective tax rate for the third quarter of 2021 was primarily a result of certain initiatives executed in the third quarter of 2021 associated with our investment in the Consumer Healthcare JV with GSK based on estimates and assumptions

17

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

that we believe to be reasonable. The negative effective tax rate for the third quarter of 2020 was primarily a result of benefits associated with certain intangible asset impairments (see Note 4(e)). The increase in the effective tax rate for the first nine months of 2021, compared to the first nine months of 2020, was due to the change in the jurisdictional mix of earnings primarily related to Comirnaty and the non-recurrence of benefits associated with certain intangible asset impairments, partially offset by certain initiatives executed in the third quarter of 2021 associated with our investment in the Consumer Healthcare JV with GSK.

We elected, with the filing of our 2018 U.S. Federal Consolidated Income Tax Return, to pay our initial estimated $15 billion repatriation tax liability on accumulated post-1986 foreign earnings over eight years through 2026. The third annual installment of this liability was paid by its April 15, 2021 due date. The fourth annual installment is due April 15, 2022 and is reported in current Income taxes payable as of October 3, 2021. The remaining liability is reported in noncurrent Other taxes payable. Our obligations may vary as a result of changes in our uncertain tax positions and/or availability of attributes such as foreign tax and other credit carryforwards.

B. Tax Contingencies

We are subject to income tax in many jurisdictions, and a certain degree of estimation is required in recording the assets and liabilities related to income taxes. All of our tax positions are subject to audit by the local taxing authorities in each tax jurisdiction. These tax audits can involve complex issues, interpretations and judgments and the resolution of matters may span multiple years, particularly if subject to negotiation or litigation.

The U.S. is one of our major tax jurisdictions, and we are regularly audited by the IRS. With respect to Pfizer, the IRS has issued Revenue Agent’s Reports (RARs) for tax years 2011-2013 and 2014-2015. We are not in agreement with the RARs and are currently appealing certain disputed issues. Tax years 2016-2018 are currently under audit. Tax years 2019-2021 are open but not under audit. All other tax years are closed. In addition to the open audit years in the U.S., we have open audit years in certain major international tax jurisdictions dating back to 2011.

For additional information, see Note 5D in our 2020 Form 10-K.

E. Derivative Financial Instruments and Hedging Activities

Foreign Exchange Risk

A significant portion of our revenues, earnings and net investments in foreign affiliates is exposed to changes in foreign exchange rates. We manage our foreign exchange risk principally through the use of derivative financial instruments and

22

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

foreign currency debt. These financial instruments serve to mitigate the impact on net income as a result of remeasurement into another currency, or against the impact of translation into U.S. dollars of certain foreign exchange-denominated transactions.

The derivative financial instruments primarily hedge or offset exposures in the euro, U.K. pound, Japanese yen and Canadian dollar. We hedge a portion of our forecasted intercompany inventory sales denominated in euro, Japanese yen, Canadian dollar, Chinese renminbi, U.K. pound and Australian dollar for up to two years.

Interest Rate Risk

Our interest-bearing investments and borrowings are subject to interest rate risk. Depending on market conditions, we may change the profile of our outstanding debt or investments by entering into derivative financial instruments like interest rate swaps, either to hedge or offset the exposure to changes in the fair value of hedged items with fixed interest rates, or to convert variable rate debt or investments to fixed rates. The derivative financial instruments primarily hedge U.S. dollar fixed-rate debt.

The following summarizes the fair value of the derivative financial instruments and notional amounts (including those reported as part of discontinued operations):

(b)The amounts reclassified from OCI into COS were:

•a net loss of $18 million in the third quarter of 2021;

•a net loss of $94 million in the first nine months of 2021;

•a net gain of $34 million in the third quarter of 2020; and

•a net gain of $184 million in the first nine months of 2020.

The remaining amounts were reclassified from OCI into OID. Based on quarter-end foreign exchange rates that are subject to change, we expect to reclassify a pre-tax gain of $202 million within the next 12 months into income. The maximum length of time over which we are hedging our exposure to the variability in future foreign exchange cash flows is approximately 22 years and relates to foreign currency debt.

(c)The amounts reclassified from OCI were reclassified into OID.

(d)Short-term borrowings and long-term debt include foreign currency borrowings which are used in net investment hedges. The short-term borrowings carrying value as of October 3, 2021 was $1.2 billion. The long-term debt carrying values as of October 3, 2021 and December 31, 2020 were $862 million and $2.1 billion, respectively.

The following summarizes cumulative basis adjustments for fair value hedges to our long-term debt:
	October 3, 2021						December 31, 2020

F. Credit Risk

A significant portion of our trade accounts receivable balances are due from wholesalers and governments. For additional information on our trade accounts receivables with significant customers, see Note 13B below and Note 17B in our 2020 Form 10-K.

As of October 3, 2021, the largest investment exposures in our portfolio represent primarily sovereign debt instruments issued by the U.S., Canada, Germany, Japan, U.K., France, Australia, Sweden, Denmark, Switzerland, and Finland.

With respect to our derivative financial instrument agreements with financial institutions, we do not expect to incur a significant loss from failure of any counterparty. Derivative financial instruments are executed under International Swaps and Derivatives Association (ISDA) master agreements with credit-support annexes that contain zero threshold provisions requiring collateral to be exchanged daily depending on levels of exposure. As a result, there are no significant concentrations of credit risk with any individual financial institution. As of October 3, 2021, the aggregate fair value of these derivative financial instruments that are in a net payable position was $357 million, for which we have posted collateral of $357 million with a corresponding amount reported in Short-term investments. As of October 3, 2021, the aggregate fair value of our derivative financial instruments that are in a net receivable position was $246 million, for which we have received collateral of $236 million with a corresponding amount reported in Short-term borrowings, including current portion of long-term debt.

(a)The increase in the gross carrying amount primarily reflects $500 million of capitalized Comirnaty sales milestones to BioNTech.

(b)The decrease is primarily due to amortization, partially offset by the capitalization of the Comirnaty milestones described above.

Amortization

Total amortization of finite-lived intangible assets was $993 million for the third quarter of 2021 and $873 million for the third quarter of 2020, and $2.8 billion for the first nine months of 2021 and $2.6 billion for the first nine months of 2020.

Note 10. Pension and Postretirement Benefit Plans

As discussed in Note 1C, we adopted a change in accounting principle to a more preferable policy under U.S. GAAP to immediately recognize actuarial gains and losses arising from the remeasurement of pension and postretirement plans. This change has been applied to all pension and postretirement plans on a retrospective basis for all prior periods presented.

The components of net periodic benefit cost/(credit) other than the service cost component are included in Other (income)/deductions––net (see Note 4).

For the nine months ended October 3, 2021, we contributed $127 million, $259 million, and $35 million to our U.S. Pension Plans, International Pension Plans, and Postretirement Plans, respectively, from our general assets, which include direct employer benefit payments.

Note 12. Contingencies and Certain Commitments

We and certain of our subsidiaries are subject to numerous contingencies arising in the ordinary course of business, including tax and legal contingencies. The following outlines our legal contingencies. For a discussion of our tax contingencies, see Note 5B.

A. Legal Proceedings

Our legal contingencies include, but are not limited to, the following:

•Patent litigation, which typically involves challenges to the coverage and/or validity of patents on various products, processes or dosage forms. We are the plaintiff in the majority of these actions. An adverse outcome in actions in which we are the plaintiff could result in loss of patent protection for a product, a significant loss of revenues from that product or impairment of the value of associated assets.

•Product liability and other product-related litigation, which can include personal injury, consumer, off-label promotion, securities, antitrust and breach of contract claims, among others, often involves highly complex issues relating to medical causation, label warnings and reliance on those warnings, scientific evidence and findings, actual, provable injury and other matters.

•Commercial and other asserted or unasserted matters, which can include acquisition-, licensing-, intellectual property-, collaboration- or co-promotion-related and product-pricing claims and environmental claims and proceedings, can involve complexities that will vary from matter to matter.

27

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

•Government investigations, which often are related to the extensive regulation of pharmaceutical companies by national, state and local government agencies in the U.S. and in other jurisdictions.

Certain of these contingencies could result in increased expenses and/or losses, including damages, fines and/or civil penalties, which could be substantial, and/or criminal charges.

We believe that our claims and defenses in matters in which we are a defendant are substantial, but litigation is inherently unpredictable and excessive verdicts do occur. We do not believe that any of these matters will have a material adverse effect on our financial position. However, we could incur judgments, enter into settlements or revise our expectations regarding the outcome of matters, which could have a material adverse effect on our results of operations and/or our cash flows in the period in which the amounts are accrued or paid.

We have accrued for losses that are both probable and reasonably estimable. Substantially all of our contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss can be complex. Consequently, we are unable to estimate the range of reasonably possible loss in excess of amounts accrued. Our assessments, which result from a complex series of judgments about future events and uncertainties, are based on estimates and assumptions that have been deemed reasonable by management, but that may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might cause us to change those estimates and assumptions.

Amounts recorded for legal and environmental contingencies can result from a complex series of judgments about future events and uncertainties and can rely heavily on estimates and assumptions. For proceedings under environmental laws to which a governmental authority is a party, we have adopted a disclosure threshold of $1 million in potential or actual governmental monetary sanctions.

The principal pending matters to which we are a party are discussed below. In determining whether a pending matter is a principal matter, we consider both quantitative and qualitative factors to assess materiality, such as, among others, the amount of damages and the nature of other relief sought, if specified; our view of the merits of the claims and of the strength of our defenses; whether the action purports to be, or is, a class action and, if not certified, our view of the likelihood that a class will be certified by the court; the jurisdiction in which the proceeding is pending; whether related actions have been transferred to multidistrict litigation; any experience that we or, to our knowledge, other companies have had in similar proceedings; whether disclosure of the action would be important to a reader of our financial statements, including whether disclosure might change a reader’s judgment about our financial statements in light of all of the information that is available to the reader; the potential impact of the proceeding on our reputation; and the extent of public interest in the matter. In addition, with respect to patent matters in which we are the plaintiff, we consider, among other things, the financial significance of the product protected by the patent(s) at issue. Some of the matters discussed below include those which management believes that the likelihood of possible loss in excess of amounts accrued is remote.

A1. Legal Proceedings––Patent Litigation

We are involved in suits relating to our patents, including but not limited to, those discussed below. Most involve claims by generic drug manufacturers that patents covering our products (or those of our collaboration/licensing partners to which we have licenses or co-promotion rights and to which we may or may not be a party), processes or dosage forms are invalid and/or do not cover the product of the generic drug manufacturer. Also, counterclaims, as well as various independent actions, have been filed alleging that our assertions of, or attempts to enforce, patent rights with respect to certain products constitute unfair competition and/or violations of antitrust laws. In addition to the challenges to the U.S. patents that are discussed below, patent rights to certain of our products or those of our collaboration/licensing partners are being challenged in various other jurisdictions. For example, some of our collaboration or licensing partners face challenges to the validity of their patent rights in non-U.S. jurisdictions. We are also party to patent damages suits in various jurisdictions pursuant to which generic drug manufacturers, payers, governments or other parties are seeking damages from us for allegedly causing delay of generic entry.

We also are often involved in other proceedings, such as inter partes review, post-grant review, re-examination or opposition proceedings, before the U.S. Patent and Trademark Office, the European Patent Office, or other foreign counterparts relating to our intellectual property or the intellectual property rights of others. Also, if one of our patents is found to be invalid by such proceedings, generic or competitive products could be introduced into the market resulting in the erosion of sales of our existing products. For example, several of the patents in our pneumococcal vaccine portfolio were challenged in inter partes review and post-grant review proceedings in the U.S. In 2017, the Patent Trial and Appeal Board (PTAB) initiated proceedings with respect to two of our pneumococcal vaccine patents. However, the PTAB declined to initiate proceedings as to two other pneumococcal vaccine patents; those two patents, and one other patent, were challenged in federal court in Delaware. In September 2021, Pfizer and a challenger entered into a settlement and license agreement, resolving all worldwide legal proceedings involving that challenger, related to our pneumococcal vaccine patents. Other challenges to pneumococcal vaccine patents remain pending at the PTAB and outside the U.S. The invalidation of any of the patents in our pneumococcal portfolio

28

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

could potentially allow additional competitor vaccines into the marketplace. In the event that any of the patents are found valid and infringed, a competitor’s vaccine might be prohibited from entering the market or a competitor might be required to pay us a royalty.

We are also subject to patent litigation pursuant to which one or more third parties seek damages and/or injunctive relief to compensate for alleged infringement of its patents by our commercial or other activities. For example, our Hospira subsidiaries are involved in patent and patent-related disputes over their attempts to bring generic pharmaceutical and biosimilar products to market. If one of our marketed products is found to infringe valid patent rights of a third party, such third party may be awarded significant damages, or we may be prevented from further sales of that product. Such damages may be enhanced as much as three-fold if we or one of our subsidiaries is found to have willfully infringed valid patent rights of a third party.

Actions In Which We Are The Plaintiff

EpiPen

In 2010, King, which we acquired in 2011 and is a wholly-owned subsidiary, brought a patent-infringement action against Sandoz in the U.S. District Court for the District of New Jersey in connection with Sandoz’s abbreviated new drug application (ANDA) filed with the FDA seeking approval to market an epinephrine injectable product. Sandoz is challenging patents, which expire in 2025, covering the next-generation autoinjector for use with epinephrine that is sold under the EpiPen brand name.

Xeljanz (tofacitinib)

Beginning in 2017, we brought patent-infringement actions against several generic manufacturers that filed separate ANDAs with the FDA seeking approval to market their generic versions of tofacitinib tablets in one or both of 5 mg and 10 mg dosage strengths, and in both immediate and extended release forms. To date, we have settled actions with several manufacturers on terms not material to us. The remaining actions continue in the U.S. District Court for the District of Delaware as described below.

In 2018, we brought a separate patent infringement action against Teva Pharmaceuticals USA, Inc. (Teva) asserting the infringement and validity of our patent covering extended release formulations of tofacitinib that was challenged by Teva in its ANDA seeking approval to market a generic version of tofacitinib 11 mg extended release tablets. In September 2021, we settled the case against Teva on terms not material to us.

In January 2021, we brought a separate patent-infringement action against Aurobindo Pharma Limited (Aurobindo) asserting the infringement and validity of the patent covering the active ingredient expiring in December 2025 and the patent covering a polymorphic form of tofacitinib expiring in 2023, which Aurobindo challenged in its ANDA seeking approval to market a generic version of tofacitinib 5 mg and 10 mg tablets.

In October 2021, we brought a separate patent-infringement action against Sinotherapeutics Inc. (Sinotherapeutics) asserting the infringement and validity of our patent covering extended release formulations of tofacitinib that was challenged by Sinotherapeutics in its ANDA seeking approval to market a generic version of tofacitinib 11 mg extended release tablets.

Inlyta (axitinib)

In 2019, Glenmark Pharmaceuticals Limited (Glenmark) notified us that it had filed an ANDA with the FDA seeking approval to market a generic version of Inlyta. Glenmark asserts the invalidity and non-infringement of the crystalline form patent for Inlyta that expires in 2030. In 2019, we filed suit against Glenmark in the U.S. District Court for the District of Delaware, asserting the validity and infringement of the crystalline form patent for Inlyta.

Ibrance (palbociclib)

In 2019, several generic companies notified us that they had filed ANDAs with the FDA seeking approval to market generic versions of Ibrance capsules. The companies asserted the invalidity and non-infringement of two composition of matter patents, one of which expires in 2023 and one of which expires in 2027, as a result of a U.S. Patent Term Extension certificate issued in January 2021, and a method of use patent covering palbociclib, which expires in 2023. In 2019, we brought patent infringement actions against each of the generic filers in various federal courts, asserting the validity and infringement of the patents challenged by the generic companies. In August 2021, the litigation concluded without settlements or a court decision.

Beginning in September 2020, we received correspondence from several generic companies notifying us that they would seek approval to market generic versions of Ibrance capsules. The generic companies assert the invalidity and non-infringement of our crystalline form patent which expires in 2034. Beginning in October 2020, we brought patent infringement actions against each of these generic companies in various federal courts, asserting the validity and infringement of the crystalline form patent. We have settled with certain of these generic companies on terms not material to the company.

Beginning in January 2021, several generic companies notified us that they had filed ANDAs with the FDA seeking approval to market generic versions of Ibrance tablets. The generic companies are challenging some or all of the following patents: (i) the

29

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

composition of matter patent expiring in 2027; (ii) the composition of matter patent expiring in 2023; (iii) the method of use patent expiring in 2023; (iv) the crystalline form patent expiring in 2034; and (v) a tablet formulation patent expiring in 2036. We brought patent infringement actions against each of the generic filers in various federal courts, asserting the validity and infringement of the patents challenged by the generic companies.

Eucrisa

Beginning in September 2021, several generic companies notified us that they had filed ANDAs with the FDA seeking approval to market generic versions of Eucrisa. The companies assert the invalidity and non-infringement of a composition of matter patent expiring in 2026, two method of use patents expiring in 2027, and one other method of use patent expiring in 2030. In 2021, we brought patent infringement actions against the generic filers in the U.S. District Court for the District of Delaware, asserting the validity and infringement of the patents challenged by the generic companies.

Matter Involving Our Collaboration/Licensing Partners

Eliquis

In 2017, twenty-five generic companies sent BMS Paragraph-IV certification letters informing BMS that they had filed ANDAs seeking approval of generic versions of Eliquis, challenging the validity and infringement of one or more of the three patents listed in the Orange Book for Eliquis. One of the patents expired in December 2019 and the remaining patents currently are set to expire in 2026 and 2031. Eliquis has been jointly developed and is being commercialized by BMS and Pfizer. BMS and Pfizer filed patent-infringement actions against all generic filers in the U.S. District Court for the District of Delaware and the U.S. District Court for the District of West Virginia, asserting that each of the generic companies’ proposed products would infringe each of the patent(s) that each generic filer challenged. Some generic filers challenged only the 2031 patent, some challenged both the 2031 and 2026 patent, and one generic company challenged all three patents. In August 2020, the U.S. District Court for the District of Delaware ruled that both the 2026 patent and the 2031 patent are valid and infringed by the proposed generic products. In August and September 2020, the generic filers appealed the District Court’s decision to the U.S. Court of Appeals for the Federal Circuit. Prior to the August 2020 ruling, we and BMS settled with certain of the companies on terms not material to us, and we and BMS may settle with other generic companies in the future. In September 2021, the U.S. Court of Appeals for the Federal Circuit affirmed the District Court’s decision.

A2. Legal Proceedings––Product Litigation

We are defendants in numerous cases, including but not limited to those discussed below, related to our pharmaceutical and other products. Plaintiffs in these cases seek damages and other relief on various grounds for alleged personal injury and economic loss.

Asbestos

Between 1967 and 1982, Warner-Lambert owned American Optical Corporation (American Optical), which manufactured and sold respiratory protective devices and asbestos safety clothing. In connection with the sale of American Optical in 1982, Warner-Lambert agreed to indemnify the purchaser for certain liabilities, including certain asbestos-related and other claims. Warner-Lambert was acquired by Pfizer in 2000 and is a wholly owned subsidiary of Pfizer. Warner-Lambert is actively engaged in the defense of, and will continue to explore various means of resolving, these claims.

Numerous lawsuits against American Optical, Pfizer and certain of its previously owned subsidiaries are pending in various federal and state courts seeking damages for alleged personal injury from exposure to products allegedly containing asbestos and other allegedly hazardous materials sold by Pfizer and certain of its previously owned subsidiaries.

There also are a small number of lawsuits pending in various federal and state courts seeking damages for alleged exposure to asbestos in facilities owned or formerly owned by Pfizer or its subsidiaries.

Effexor

Beginning in 2011, actions, including purported class actions, were filed in various federal courts against Wyeth and, in certain of the actions, affiliates of Wyeth and certain other defendants relating to Effexor XR, which is the extended-release formulation of Effexor. The plaintiffs in each of the class actions seek to represent a class consisting of all persons in the U.S. and its territories who directly purchased, indirectly purchased or reimbursed patients for the purchase of Effexor XR or generic Effexor XR from any of the defendants from June 14, 2008 until the time the defendants’ allegedly unlawful conduct ceased. The plaintiffs in all of the actions allege delay in the launch of generic Effexor XR in the U.S. and its territories, in violation of federal antitrust laws and, in certain of the actions, the antitrust, consumer protection and various other laws of certain states, as the result of Wyeth fraudulently obtaining and improperly listing certain patents for Effexor XR in the Orange Book, enforcing certain patents for Effexor XR and entering into a litigation settlement agreement with a generic drug manufacturer with respect to Effexor XR. Each of the plaintiffs seeks treble damages (for itself in the individual actions or on behalf of the putative class

30

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

in the purported class actions) for alleged price overcharges for Effexor XR or generic Effexor XR in the U.S. and its territories since June 14, 2008. All of these actions have been consolidated in the U.S. District Court for the District of New Jersey.

In 2014, the District Court dismissed the direct purchaser plaintiffs’ claims based on the litigation settlement agreement, but declined to dismiss the other direct purchaser plaintiff claims. In 2015, the District Court entered partial final judgments as to all settlement agreement claims, including those asserted by direct purchasers and end-payer plaintiffs, which plaintiffs appealed to the U.S. Court of Appeals for the Third Circuit. In 2017, the U.S. Court of Appeals for the Third Circuit reversed the District Court’s decisions and remanded the claims to the District Court.

Lipitor

Beginning in 2011, purported class actions relating to Lipitor were filed in various federal courts against, among others, Pfizer, certain Pfizer affiliates, and, in most of the actions, Ranbaxy and certain Ranbaxy affiliates. The plaintiffs in these various actions seek to represent nationwide, multi-state or statewide classes consisting of persons or entities who directly purchased, indirectly purchased or reimbursed patients for the purchase of Lipitor (or, in certain of the actions, generic Lipitor) from any of the defendants from March 2010 until the cessation of the defendants’ allegedly unlawful conduct (the Class Period). The plaintiffs allege delay in the launch of generic Lipitor, in violation of federal antitrust laws and/or state antitrust, consumer protection and various other laws, resulting from (i) the 2008 agreement pursuant to which Pfizer and Ranbaxy settled certain patent litigation involving Lipitor and Pfizer granted Ranbaxy a license to sell a generic version of Lipitor in various markets beginning on varying dates, and (ii) in certain of the actions, the procurement and/or enforcement of certain patents for Lipitor. Each of the actions seeks, among other things, treble damages on behalf of the putative class for alleged price overcharges for Lipitor (or, in certain of the actions, generic Lipitor) during the Class Period. In addition, individual actions have been filed against Pfizer, Ranbaxy and certain of their affiliates, among others, that assert claims and seek relief for the plaintiffs that are substantially similar to the claims asserted and the relief sought in the purported class actions described above. These various actions have been consolidated for pre-trial proceedings in a Multi-District Litigation in the U.S. District Court for the District of New Jersey.

In September 2013 and 2014, the District Court dismissed with prejudice the claims of the direct purchasers. In October and November 2014, the District Court dismissed with prejudice the claims of all other Multi-District Litigation plaintiffs. All plaintiffs have appealed the District Court’s orders dismissing their claims with prejudice to the U.S. Court of Appeals for the Third Circuit. In addition, the direct purchaser class plaintiffs appealed the order denying their motion to amend the judgment and for leave to amend their complaint to the Court of Appeals. In 2017, the Court of Appeals reversed the District Court’s decisions and remanded the claims to the District Court.

Also, in 2013, the State of West Virginia filed an action in West Virginia state court against Pfizer and Ranbaxy, among others, that asserts claims and seeks relief on behalf of the State of West Virginia and residents of that state that are substantially similar to the claims asserted and the relief sought in the purported class actions described above.

EpiPen (Direct Purchaser)

In February 2020, a lawsuit was filed in the U.S. District Court for the District of Kansas against Pfizer, its affiliates King and Meridian, and various Mylan entities, on behalf of a purported U.S. nationwide class of direct purchaser plaintiffs who purchased EpiPen devices directly from the defendants. Plaintiffs in this action generally allege that Pfizer and Mylan conspired to delay market entry of generic EpiPen through the settlement of patent litigation regarding EpiPen, and thereby delayed market entry of generic EpiPen in violation of federal antitrust law. Plaintiffs seek treble damages for alleged overcharges for EpiPen since 2011. In July 2021, the District Court granted defendants’ motion to dismiss the direct purchaser complaint, without prejudice. In September 2021, plaintiffs filed an amended complaint.

Nexium 24HR and Protonix

A number of individual and multi-plaintiff lawsuits have been filed against Pfizer, certain of its subsidiaries and/or other pharmaceutical manufacturers in various federal and state courts alleging that the plaintiffs developed kidney-related injuries purportedly as a result of the ingestion of certain proton pump inhibitors. The cases against Pfizer involve Protonix and/or Nexium 24HR and seek compensatory and punitive damages and, in some cases, treble damages, restitution or disgorgement. In 2017, the federal actions were ordered transferred for coordinated pre-trial proceedings to a Multi-District Litigation in the U.S. District Court for the District of New Jersey. As part of our Consumer Healthcare JV transaction with GSK, the JV has agreed to assume, and to indemnify Pfizer for, liabilities arising out of such litigation to the extent related to Nexium 24HR.

Docetaxel

•Personal Injury Actions

A number of lawsuits have been filed against Hospira and Pfizer in various federal and state courts alleging that plaintiffs who were treated with Docetaxel developed permanent hair loss. The significant majority of the cases also name other defendants, including the manufacturer of the branded product, Taxotere. Plaintiffs seek compensatory and punitive damages.

In 2016, the federal cases were transferred for coordinated pre-trial proceedings to a Multi-District Litigation in the U.S. District Court for the Eastern District of Louisiana.

•Mississippi Attorney General Government Action

In 2018, the Attorney General of Mississippi filed a complaint in Mississippi state court against the manufacturer of the branded product and eight other manufacturers including Pfizer and Hospira, alleging, with respect to Pfizer and Hospira, a failure to warn about a risk of permanent hair loss in violation of the Mississippi Consumer Protection Act. The action seeks civil penalties and injunctive relief.

Array Securities Litigation

In 2017, two purported class actions were filed in the U.S. District Court for the District of Colorado alleging that Array, which we acquired in 2019 and is our wholly owned subsidiary, and certain of its former officers violated federal securities laws in connection with certain disclosures made, or omitted, by Array regarding the NRAS-mutant melanoma program. In 2018, the actions were consolidated into a single proceeding. In March 2021, the parties reached an agreement in principle to resolve the litigation on terms not material to Pfizer.

Zantac

A number of lawsuits have been filed against Pfizer in various federal and state courts alleging that plaintiffs developed various types of cancer, or face an increased risk of developing cancer, purportedly as a result of the ingestion of Zantac. The significant majority of these cases also name other defendants that have historically manufactured and/or sold Zantac. Pfizer has not sold Zantac since 2006, and only sold an OTC version of the product. Plaintiffs seek compensatory and punitive damages.

In February 2020, the federal actions were transferred for coordinated pre-trial proceedings to a Multi-District Litigation in the U.S. District Court for the Southern District of Florida. Plaintiffs in the Multi-District Litigation have filed against Pfizer and many other defendants a master personal injury complaint, a consolidated consumer class action complaint alleging, among other things, claims under consumer protection statutes of all 50 states, and a medical monitoring complaint seeking to certify medical monitoring classes under the laws of 13 states. Plaintiffs previously had filed a consolidated third-party payor class action complaint alleging violation of the RICO statute and seeking reimbursement for payments made for the prescription version of Zantac, but the Multi-District Litigation court dismissed that complaint; Plaintiffs have appealed the dismissal to the U.S. Court of Appeals for the Eleventh Circuit. In addition, (i) Pfizer has received service of two Canadian class action complaints naming Pfizer and other defendants, and seeking compensatory and punitive damages for personal injury and economic loss, allegedly arising from the defendants’ sale of Zantac in Canada; and (ii) the State of New Mexico and the Mayor and City Council of Baltimore separately filed civil actions against Pfizer and many other defendants in state court, alleging various state statutory and common law claims in connection with the defendants’ alleged sale of Zantac in those jurisdictions. In April 2021, a Judicial Council Coordinated Proceeding was created in the Superior Court of California in Alameda County to coordinate personal injury actions against Pfizer and other defendants filed in California state court.

Chantix

Beginning in August 2021, a number of putative class actions have been filed against Pfizer in various U.S. federal courts following Pfizer’s voluntary recall of Chantix due to the presence of a nitrosamine, N-nitroso-varenicline. Plaintiffs assert that they suffered economic harm purportedly as a result of purchasing Chantix or generic varenicline medicines sold by Pfizer. Plaintiffs seek to represent nationwide and state-specific classes and seek various remedies, including damages and medical monitoring. Similar putative class actions have been filed in Canada and Israel, where the product brand is Champix.

A3. Legal Proceedings––Commercial and Other Matters

Monsanto-Related Matters

In 1997, Monsanto Company (Former Monsanto) contributed certain chemical manufacturing operations and facilities to a newly formed corporation, Solutia Inc. (Solutia), and spun off the shares of Solutia. In 2000, Former Monsanto merged with Pharmacia & Upjohn Company to form Pharmacia. Pharmacia then transferred its agricultural operations to a newly created subsidiary, named Monsanto Company (New Monsanto), which it spun off in a two-stage process that was completed in 2002. Pharmacia was acquired by Pfizer in 2003 and is a wholly owned subsidiary of Pfizer.

In connection with its spin-off that was completed in 2002, New Monsanto assumed, and agreed to indemnify Pharmacia for, any liabilities related to Pharmacia’s former agricultural business. New Monsanto has defended and/or is defending Pharmacia in connection with various claims and litigation arising out of, or related to, the agricultural business, and has been indemnifying Pharmacia when liability has been imposed or settlement has been reached regarding such claims and litigation.

In connection with its spin-off in 1997, Solutia assumed, and agreed to indemnify Pharmacia for, liabilities related to Former Monsanto’s chemical businesses. As the result of its reorganization under Chapter 11 of the U.S. Bankruptcy Code, Solutia’s

32

(UNAUDITED)

indemnification obligations relating to Former Monsanto’s chemical businesses are primarily limited to sites that Solutia has owned or operated. In addition, in connection with its spin-off that was completed in 2002, New Monsanto assumed, and agreed to indemnify Pharmacia for, any liabilities primarily related to Former Monsanto’s chemical businesses, including, but not limited to, any such liabilities that Solutia assumed. Solutia’s and New Monsanto’s assumption of, and agreement to indemnify Pharmacia for, these liabilities apply to pending actions and any future actions related to Former Monsanto’s chemical businesses in which Pharmacia is named as a defendant, including, without limitation, actions asserting environmental claims, including alleged exposure to polychlorinated biphenyls. Solutia and/or New Monsanto are defending Pharmacia in connection with various claims and litigation arising out of, or related to, Former Monsanto’s chemical businesses, and have been indemnifying Pharmacia when liability has been imposed or settlement has been reached regarding such claims and litigation.

Environmental Matters

In 2009, we submitted a revised site-wide feasibility study with regard to the Wyeth Holdings Corporation (formerly, American Cyanamid Company) discontinued industrial chemical facility in Bound Brook, New Jersey. In 2011, Wyeth Holdings Corporation executed an Administrative Settlement Agreement and Order on Consent for Removal Action (the 2011 Administrative Settlement Agreement) with the U.S. Environmental Protection Agency (EPA) with regard to the Bound Brook facility. In accordance with the 2011 Administrative Settlement Agreement, we completed construction of an interim remedy. In 2012, the EPA issued a final remediation plan for the Bound Brook facility’s main plant area. In 2013, Wyeth Holdings Corporation (now Wyeth Holdings LLC) entered into an Administrative Settlement Agreement and Order on Consent with the EPA to allow us to undertake detailed engineering design of the remedy for the main plant area and to perform a focused feasibility study for two adjacent lagoons. In 2015, the U.S., on behalf of the EPA, filed a complaint and consent decree with the federal District Court for the District of New Jersey that allows Wyeth Holdings LLC to complete the design and to implement the remedy for the main plant area. The consent decree (which supersedes the 2011 Administrative Settlement Agreement) was entered by the District Court in 2015. In 2018, the EPA issued a final remediation plan for the two adjacent lagoons. In 2019, Wyeth Holdings LLC entered into an Administrative Settlement Agreement and Order on Consent with the EPA to allow us to undertake detailed engineering design of the remedy for the lagoons. In September 2021, the U.S., on behalf of the EPA, filed a complaint and consent decree with the federal District Court for the District of New Jersey that will allow Wyeth Holdings LLC to complete the design and implement the remedy for the two adjacent lagoons.

We have accrued for the estimated costs of the site remedies for the Bound Brook facility.

We are a party to a number of other proceedings brought under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended, and other state, local or foreign laws in which the primary relief sought is the cost of past and/or future remediation.

Contracts with Iraqi Ministry of Health

In 2017, a number of U.S. service members, civilians, and their families brought a complaint in the U.S. District Court for the District of Columbia against a number of pharmaceutical and medical devices companies, including Pfizer and certain of its subsidiaries, alleging that the defendants violated the U.S. Anti-Terrorism Act. The complaint alleges that the defendants provided funding for terrorist organizations through their sales practices pursuant to pharmaceutical and medical device contracts with the Iraqi Ministry of Health, and seeks monetary relief. In July 2020, the District Court granted defendants’ motions to dismiss and dismissed all of plaintiffs’ claims. The plaintiffs are appealing the District Court’s decision.

Allergan Complaint for Indemnity

In 2019, Pfizer was named as a defendant in a complaint, along with King, filed by Allergan Finance LLC (Allergan) in the Supreme Court of the State of New York, asserting claims for indemnity related to Kadian, which was owned for a short period by King in 2008, prior to Pfizer's acquisition of King in 2010. This suit was voluntarily discontinued without prejudice in January 2021.

Breach of Contract––Xalkori/Lorbrena

We are a defendant in a breach of contract action brought by New York University (NYU) in the Supreme Court of the State of New York (Supreme Court). NYU alleges that it is entitled to royalties on Pfizer’s sales of Xalkori under the terms of a Research and License Agreement between NYU and Sugen, Inc. Sugen, Inc. was acquired by Pharmacia in August 1999, and Pharmacia was acquired by Pfizer in 2003 and is a wholly owned subsidiary of Pfizer. The action was originally filed in 2013. In 2015, the Supreme Court dismissed the action and, in 2017, the New York State Appellate Division reversed the decision and remanded the proceedings to the Supreme Court. In January 2020, the Supreme Court denied both parties’ summary judgment motions.

In October 2020, NYU filed a separate breach of contract action against Pfizer alleging that it is entitled to royalties on sales of Lorbrena under the terms of the same NYU-Sugen, Inc. Research and Licensing Agreement.

A4. Legal Proceedings––Government Investigations

We are subject to extensive regulation by government agencies in the U.S., other developed markets and multiple emerging markets in which we operate. Criminal charges, substantial fines and/or civil penalties, limitations on our ability to conduct business in applicable jurisdictions, corporate integrity or deferred prosecution agreements, as well as reputational harm and increased public interest in the matter could result from government investigations in the U.S. and other jurisdictions in which we do business. In addition, in a qui tam lawsuit in which the government declines to intervene, the relator may still pursue a suit for the recovery of civil damages and penalties on behalf of the government. Among the investigations by government agencies are the matters discussed below.

Greenstone Investigations

•U.S. Department of Justice Antitrust Division Investigation

Since July 2017, the U.S. Department of Justice's Antitrust Division has been investigating our former Greenstone generics business. We believe this is related to an ongoing broader antitrust investigation of the generic pharmaceutical industry. We have produced records relating to this investigation.

•State Attorneys General Generics Antitrust Litigation

In April 2018, Greenstone received requests for information from the Antitrust Department of the Connecticut Office of the Attorney General. In May 2019, Attorneys General of more than 40 states plus the District of Columbia and Puerto Rico filed a complaint against a number of pharmaceutical companies, including Greenstone and Pfizer. The matter has been consolidated with a Multi-District Litigation in the Eastern District of Pennsylvania. As to Greenstone and Pfizer, the complaint alleges anticompetitive conduct in violation of federal and state antitrust laws and state consumer protection laws. In June 2020, the State Attorneys General filed a new complaint against a large number of companies, including Greenstone and Pfizer, making similar allegations, but concerning a new set of drugs. This complaint was transferred to the Multi-District Litigation in July 2020.

Subpoena relating to Manufacturing of Quillivant XR

In October 2018, we received a subpoena from the U.S. Attorney’s Office for the Southern District of New York (SDNY) seeking records relating to our relationship with another drug manufacturer and its production and manufacturing of drugs including, but not limited to, Quillivant XR. We have produced records pursuant to the subpoena.

Government Inquiries relating to Meridian Medical Technologies

In February 2019, we received a civil investigative demand from the U.S. Attorney’s Office for the SDNY. The civil investigative demand seeks records and information related to alleged quality issues involving the manufacture of auto-injectors at our Meridian site. In August 2019, we received a HIPAA subpoena from the U.S. Attorney’s Office for the Eastern District of Missouri seeking similar records and information. We are producing records in response to these requests.

U.S. Department of Justice/SEC Inquiry relating to Russian Operations

In June 2019, we received an informal request from the U.S. Department of Justice’s Foreign Corrupt Practices Act (FCPA) Unit seeking documents relating to our operations in Russia. In September 2019, we received a similar request from the SEC’s FCPA Unit. We have produced records pursuant to these requests.

Docetaxel––Mississippi Attorney General Government Investigation

See Legal Proceedings––Product Litigation––Docetaxel––Mississippi Attorney General Government Investigation above for information regarding a government investigation related to Docetaxel marketing practices.

U.S. Department of Justice Inquiries relating to India Operations

In March 2020, we received an informal request from the U.S. Department of Justice's Consumer Protection Branch seeking documents relating to our manufacturing operations in India, including at our former facility located at Irrungattukottai in India. In April 2020, we received a similar request from the U.S. Attorney’s Office for the SDNY regarding a civil investigation concerning operations at our facilities in India. We are producing records pursuant to these requests.

U.S. Department of Justice/SEC Inquiry relating to China Operations

In June 2020, we received an informal request from the U.S. Department of Justice's FCPA Unit seeking documents relating to our operations in China. In August 2020, we received a similar request from the SEC’s FCPA Unit. We are producing records pursuant to these requests.

A5. Legal Proceedings––Matters Resolved During the First Nine Months of 2021

During the first nine months of 2021, certain matters, including the matter discussed below, were resolved or became the subject of definitive settlement agreements or settlement agreements-in-principle.

EpiPen

Beginning in 2017, purported class actions were filed in various federal courts by indirect purchasers of EpiPen against Pfizer, and/or its affiliates King and Meridian, and/or various entities affiliated with Mylan, and Mylan former Chief Executive Officer, Heather Bresch. The plaintiffs in these actions represent U.S. nationwide classes comprising persons or entities who paid for any portion of the end-user purchase price of an EpiPen between 2009 until the cessation of the defendants’ allegedly unlawful conduct. Against Pfizer and/or its affiliates, plaintiffs in these actions generally allege that Pfizer’s and/or its affiliates’ settlement of patent litigation regarding EpiPen delayed market entry of generic EpiPen in violation of federal and various state antitrust laws. At least one lawsuit also alleges that Pfizer and/or Mylan violated the federal Racketeer Influenced and Corrupt Organizations Act (RICO). Plaintiffs also filed various federal antitrust, state consumer protection and unjust enrichment claims against, and relating to conduct attributable solely to, Mylan and/or its affiliates regarding EpiPen. Plaintiffs seek treble damages for alleged overcharges for EpiPen since 2011. In 2017, all of these indirect purchase actions were consolidated for coordinated pre-trial proceedings in a Multi-District Litigation in the U.S. District Court for the District of Kansas with other EpiPen-related actions against Mylan and/or its affiliates to which Pfizer, King and Meridian are not parties. In July 2021, Pfizer and plaintiffs filed a stipulation of settlement to resolve the Multi-District Litigation for $345 million. The settlement is subject to court approval, and the payment has been made in accordance with the terms of the settlement agreement.

B. Guarantees and Indemnifications

In the ordinary course of business and in connection with the sale of assets and businesses and other transactions, we often indemnify our counterparties against certain liabilities that may arise in connection with the transaction or that are related to events and activities prior to or following a transaction. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we may be required to reimburse the loss. These indemnifications are generally subject to various restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of October 3, 2021, the estimated fair value of these indemnification obligations was not significant.

In addition, in connection with our entry into certain agreements and other transactions, our counterparties may agree to indemnify us. For example, in November 2020, we and Mylan completed the transaction to spin-off our Upjohn Business and combine it with Mylan to form Viatris. As part of the transaction and as previously disclosed, Viatris has agreed to assume, and to indemnify Pfizer for, liabilities arising out of certain matters.

We have also guaranteed the long-term debt of certain companies that we acquired, which are now subsidiaries of Pfizer. See Note 7D.

C. Contingent Consideration for Acquisitions

We may be required to make payments to sellers for certain prior business combinations that are contingent upon future events or outcomes. For additional information, see Note 1D in our 2020 Form 10-K.

Deferred Revenues

Our deferred revenues primarily relate to advance payments received or receivable in connection with contracts that we entered into during 2021 and 2020 with various government or government sponsored customers in international markets for supply of Comirnaty. The deferred revenues associated with the advance payments related to Comirnaty total $3.7 billion as of October 3, 2021 and $957 million as of December 31, 2020, with $3.4 billion and $264 million recorded in current liabilities and noncurrent liabilities, respectively as of October 3, 2021, and $957 million recorded in current liabilities as of December 31, 2020. The increase in the Comirnaty deferred revenues during the first nine months of 2021 was the result of additional advance

payments received as we entered into new or amended contracts or as we invoiced customers in advance of vaccine deliveries less amounts recognized in Revenues as we delivered doses to our customers. During the third quarter and first nine months of 2021, we recognized revenue of $136 million and $950 million, respectively, that was included in the balance of Comirnaty deferred revenues as of December 31, 2020. The Comirnaty deferred revenues as of October 3, 2021 will be recognized in Revenues proportionately as we deliver doses of the vaccine to our customers and satisfy our performance obligation under the contracts, with the amounts included in current liabilities expected to be recognized in Revenues within the next 12 months, and the amounts included in noncurrent liabilities expected to be recognized in Revenues in the fourth quarter of 2022 and in 2023.

ITEM 2. MANAGEMENTS’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

OVERVIEW OF OUR PERFORMANCE, OPERATING ENVIRONMENT, STRATEGY AND OUTLOOK

Our Business and Strategy

Most of our revenues come from the manufacture and sale of biopharmaceutical products. With the formation of the Consumer Healthcare JV in 2019 and the completion of the spin-off and combination of our Upjohn Business with Mylan in November 2020, Pfizer has transformed into a focused, global leader in science-based innovative medicines and vaccines. We operate as a single operating segment engaged in the discovery, development, manufacturing, marketing, sale and distribution of biopharmaceutical products worldwide. The financial results of the Upjohn Business and the Mylan-Japan collaboration are reflected as discontinued operations. Prior-period information has been restated to reflect our current organization structure. We expect to incur costs of approximately $700 million in connection with separating Upjohn, of which approximately 75% has been incurred since inception and through the third quarter of 2021. These charges include costs and expenses related to separation of legal entities and transaction costs.

For additional information about our business, strategy and operating environment, see the Item 1. Business section and Overview of Our Performance, Operating Environment, Strategy and Outlook section within MD&A of our 2020 Form 10-K.

References to operational variances pertain to period-over-period changes that exclude the impact of foreign exchange rates. Although foreign exchange rate changes are part of our business, they are not within our control and since they can mask positive or negative trends in the business, we believe presenting operational variances excluding these foreign exchange changes provides useful information to evaluate our results.

Our Business Development Initiatives

We are committed to strategically capitalizing on growth opportunities by advancing our own product pipeline and maximizing the value of our existing products, as well as through various business development activities.

Our significant recent business development activities include:

Collaboration with Biohaven––In November 2021, we entered into a collaboration and license agreement and related sublicense agreement with Biohaven Pharmaceutical Holding Company Ltd., Biohaven Pharmaceutical Ireland DAC and Bioshin LTD. (collectively, Biohaven) pursuant to which we will acquire rights to commercialize rimegepant and zavegepant for the treatment and prevention of migraines outside of the U.S., subject to regulatory approval. Rimegepant is currently commercialized in the U.S. under the brand name Nurtec® ODT, with certain applications pending outside of the U.S. Biohaven will continue to lead R&D globally and we have the exclusive right to commercialization globally, outside of the U.S. Under the financial terms of the transaction agreements, we will make an upfront payment of $500 million, consisting of $150 million cash and $350 million in the purchase of Biohaven equity. Biohaven is also eligible to receive up to $740 million in non-U.S. commercialization milestones, in addition to tiered double-digit royalties on net sales outside of the U.S. In addition to the milestones and royalties above, we will also reimburse Biohaven for the portion of certain additional milestones and royalties due to third parties in accordance with preexisting agreements, which are attributed to ex-U.S. sales. The transaction is subject to customary closing conditions, including completion of review under applicable antitrust laws.

Agreement with Altaris Capital Partners, LLC (Altaris)––In November 2021, we entered into an agreement with Altaris, a healthcare investment firm based in New York, for Altaris to purchase Meridian. Meridian was acquired by Pfizer in 2011 as part of the King Pharmaceuticals acquisition and has maintained relative operational autonomy since that time. Meridian’s operations, which generate approximately $300 million in annual revenues, consist of manufacturing and distributing medical countermeasures used by the U.S. Department of Defense, Emergency Medical Services, Homeland Security and foreign ministries of health and defense, as well as rescue auto-injectors for the emergency treatment of allergic reactions including anaphylaxis. The transaction is expected to close in the coming months, subject to customary closing conditions including the receipt of regulatory approvals.

Acquisition of Trillium Therapeutics Inc. (Trillium)––In August 2021, we and Trillium announced that the companies entered into a definitive agreement under which we will acquire Trillium, a clinical stage immuno-oncology company developing innovative therapies for the treatment of cancer. We currently hold a 2% ownership investment in Trillium. Under the terms of the agreement, we will acquire all outstanding shares of Trillium not already owned by us for $18.50 per share, in cash, or an aggregate purchase price of approximately $2.2 billion. The acquisition is expected to close in the fourth quarter of 2021 or first half of 2022, subject to customary closing conditions, including regulatory approvals.

39

Collaboration with Arvinas, Inc. (Arvinas)––In July 2021, we announced a global collaboration with Arvinas to develop and commercialize ARV-471, an investigational oral PROTAC® (PROteolysis TArgeting Chimera) estrogen receptor protein degrader. See Note 2 for additional information.

Acquisition of Amplyx Pharmaceuticals, Inc. (Amplyx)––In April 2021, we announced that we acquired Amplyx, a privately-held company dedicated to the development of therapies for debilitating and life-threatening diseases that affect people with compromised immune systems. Amplyx’s lead compound, Fosmanogepix (APX001), is a novel investigational asset in Phase 2 development for the treatment of invasive fungal infections.

Our Third Quarter 2021 and First Nine Months of 2021 Performance

Revenues

Revenues increased $13.8 billion, or 134%, in the third quarter of 2021 to $24.1 billion from $10.3 billion in the third quarter of 2020, reflecting an operational increase of $13.4 billion, or 130%, as well as a favorable impact of foreign exchange of $421 million, or 4%. Excluding direct sales and alliance revenues of Comirnaty of $13.0 billion, revenues increased 7% operationally, reflecting strong growth in Eliquis, Vyndaqel/Vyndamax, Inlyta, Xtandi, Biosimilars and the Hospital therapeutic area, partially offset by declines in Chantix/Champix, Prevnar family, Sutent, Xeljanz and Enbrel.

Revenues increased $27.4 billion, or 91%, in the first nine months of 2021 to $57.7 billion from $30.2 billion in the first nine months of 2020, reflecting an operational increase of $26.1 billion, or 86%, as well as a favorable impact of foreign exchange of $1.3 billion, or 4%. Excluding direct sales and alliance revenues of Comirnaty of $24.3 billion, revenues increased 8% operationally, reflecting strong growth in Eliquis, Vyndaqel/Vyndamax, Inlyta, Xtandi, Biosimilars and the Hospital therapeutic area, partially offset by declines in Chantix/Champix, Prevnar family, Enbrel and Sutent.

See the Analysis of the Condensed Consolidated Statements of Income––Revenues by Geography and Revenues––Selected Product Discussion sections for more information, including a discussion of key drivers of our revenue performance. For information regarding the primary indications or class of certain products, see Note 13B.

Income from Continuing Operations Before Provision/(Benefit) for Taxes on Income

The increases in Income from continuing operations before provision/(benefit) for taxes on income of $7.3 billion in the third quarter of 2021 and $13.7 billion in the first nine months of 2021, compared to the same periods in 2020, respectively, were primarily attributable to: (i) higher revenues, (ii) net periodic benefit credits in 2021 versus net periodic benefit costs in 2020, (iii) net gains on equity securities in the third quarter of 2021 versus net losses on equity securities in the third quarter of 2020, and higher net gains on equity securities in the first nine months of 2021 and (iv) the non-recurrence of certain asset impairment charges in 2020, partially offset by (v) increases in: Cost of sales, Research and development expenses, Selling, informational and administrative expenses and Restructuring charges and certain acquisition-related costs.

See the Analysis of the Condensed Consolidated Statements of Income within this MD&A and Note 4 for additional information.

For information on our tax provision and effective tax rate, see the Provision/(Benefit) for Taxes on Income section within MD&A and Note 5.

Our Operating Environment

We, like other businesses in our industry, are subject to certain industry-specific challenges. These include, among others, the topics listed below and in our 2020 Form 10-K.

Intellectual Property Rights and Collaboration/Licensing Rights

The loss, expiration or invalidation of intellectual property rights, patent litigation settlements with manufacturers and the expiration of co-promotion and licensing rights can have a material adverse effect on our revenues. Certain of our products have experienced patent-based expirations or loss of regulatory exclusivity in certain markets in the last few years, and we expect certain products to face significantly increased generic competition over the next few years. Examples of products experiencing recent expirations of their basic product patent are Chantix in the U.S. in November 2020 and Sutent in the U.S. in August 2021. While additional patent expiries will continue, we expect a moderate impact of reduced revenues due to patent expiries from 2021 through 2025. Further, legal or regulatory action by various stakeholders or governments could potentially result in us not seeking intellectual property protection for or agreeing not to enforce or being restricted from enforcing intellectual property related to our products. For example, in May 2021, the Brazilian Supreme Court voted to invalidate Article 40 of

40

Brazil’s Patent Law, which guaranteed a minimum 10-year patent term from patent grant, and to give retroactive effect to such decision. We continue to vigorously defend our patent rights against infringement, and we will continue to support efforts that strengthen worldwide recognition of patent rights while taking necessary steps to ensure appropriate patient access.

For additional information on patent rights we consider most significant in relation to our business as a whole, see the Item 1. Business––Patents and Other Intellectual Property Rights section of our 2020 Form 10-K. For a discussion of recent developments with respect to patent litigation, see Note 12A1.

Regulatory Environment/Pricing and Access––Government and Other Payer Group Pressures

The pricing of medicines and vaccines by pharmaceutical manufacturers and the cost of healthcare, which includes medicines, vaccines, medical services and hospital services, continues to be important to payers, governments, patients, and other stakeholders. Federal and state governments and private third-party payers in the U.S. continue to take action to manage the utilization of drugs and cost of drugs, including increasingly employing formularies to control costs by taking into account discounts in connection with decisions about formulary inclusion or favorable formulary placement. We consider a number of factors impacting the pricing of our medicines and vaccines. Within the U.S., we often engage with patients, doctors and healthcare plans. We also often provide significant discounts from the list price to insurers, including PBMs and MCOs. The price that patients pay in the U.S. for prescribed medicines and vaccines is ultimately set by healthcare providers and insurers. Governments globally may use a variety of measures to control costs, including proposing pricing reform or legislation, cross country collaboration and procurement, price cuts, mandatory rebates, health technology assessments, forced localization as a condition of market access, “international reference pricing” (i.e., the practice of a country linking its regulated medicine prices to those of other countries), quality consistency evaluation processes and volume-based procurement. In the U.S., we expect to see continued focus by Congress and the Biden Administration on regulating pricing resulting in legislative and regulatory efforts designed to control costs. Congress is currently considering a budget reconciliation package that includes drug pricing changes to Medicare Part B and D. We anticipate that these and similar initiatives will continue to increase pricing pressures globally. For additional information, see the Item 1. Business––Pricing Pressures and Managed Care Organizations and ––Government Regulation and Price Constraints sections in our 2020 Form 10-K.

Product Supply

We periodically encounter supply delays, disruptions and shortages, including due to a voluntary recall of a product. In July and August, Pfizer recalled 16 lots of Chantix in the U.S. due to the presence of a nitrosamine, N-nitroso-varenicline, at or above the FDA interim acceptable intake limit. In September 2021, Pfizer expanded its voluntary recall in the U.S. to include all lots of Chantix. We currently also have a voluntary recall across multiple markets and a global pause in shipments of Chantix. Nitrosamines are impurities common in water and foods and everyone is exposed to some level of nitrosamines. In response to requests from various regulatory authorities, manufacturers across the pharmaceutical industry, including Pfizer, have been evaluating the potential for the presence or formation of nitrosamines in pharmaceutical products. We are currently undertaking an evaluation of our entire portfolio. For information on risks related to product manufacturing, see the Item 1A. Risk Factors––Product Manufacturing, Sales and Marketing Risks section of our 2020 Form 10-K.

The Global Economic Environment

In addition to the industry-specific factors discussed above, we, like other businesses of our size and global extent of activities, are exposed to the economic cycle. For additional information, please see the Overview of Our Performance, Operating Environment, Strategy and Outlook––The Global Economic Environment section of the MD&A of our 2020 Form 10-K.

COVID-19 Pandemic

The continuation of the COVID-19 pandemic has impacted our business, operations and financial condition and results.

Our Response to COVID-19

We are committed to confronting the public health challenge posed by the pandemic by collaborating with industry partners, global regulators and academic institutions to develop potential approaches to prevent and treat COVID-19. We have made some important advances, including, among others:

•COVID-19 Vaccine Development Program:

◦The FDA has approved Comirnaty in the U.S. to prevent COVID-19 in individuals 16 years of age and older as a two-dose primary series (30 µg per dose). Comirnaty is the first COVID-19 vaccine to be granted approval by the FDA and had previously been available to this patient population in the U.S. under an EUA since December 2020. The vaccine remains available to individuals 12 to 15 years old under an EUA granted by the FDA in May 2021. Emergency use and distribution of this product is subject to the conditions set forth in the EUA, and only for the duration of the declaration by the Department of Health & Human Services that circumstances exist justifying authorization of emergency use of drugs

41

and biological products during the COVID-19 pandemic under Section 564 of the U.S. Federal Food, Drug and Cosmetic Act (the Declaration), or until revocation of the EUA by the FDA. The FDA has issued EUAs to certain other companies for products intended for the prevention or treatment of COVID-19 and may continue to do so during the duration of the Declaration. In September 2021, the FDA authorized for emergency use a booster dose of Comirnaty/BNT162b2 for individuals 65 years of age and older, individuals 18 through 64 years of age at high risk of severe COVID-19, and individuals 18 through 64 years of age with frequent institutional or occupational exposure to SARS-CoV-2. In addition, in October 2021, the FDA authorized for emergency use a booster dose to eligible individuals who have completed primary vaccination with a different authorized COVID-19 vaccine. The FDA also authorized BNT162b2 (10 µg per dose) for emergency use for children 5 through 11 years of age. In November 2021, we and BioNTech submitted a request to the FDA to amend the EUA of a booster dose of Comirnaty/BNT162b2 to include all individuals 18 years of age and older. Comirnaty/BNT162b2 has been granted an approval or a temporary authorization in many other countries around the world in populations varying by country. We continue to evaluate our vaccine, including for potential maternal and additional pediatric indications, and the short- and long-term efficacy of Comirnaty. We are also studying vaccines to potentially prevent COVID-19 caused by new and emerging variants or an updated vaccine as needed.

◦The companies have entered into agreements to supply pre-specified doses of Comirnaty with multiple developed and emerging countries around the world and are continuing to deliver doses of Comirnaty to governments under such agreements. We also signed agreements with multiple countries to supply Comirnaty doses in 2022 and beyond and are currently negotiating similar potential agreements with multiple other countries.

◦As of November 2, 2021, we forecasted approximately $36.0 billion in revenues in 2021 from Comirnaty, with gross profit to be split evenly with BioNTech, reflecting approximately 2.3 billion doses that are expected to be delivered in fiscal 2021 based on expected ordering patterns through the end of December 2021 for the U.S. and through the end of November 2021 for the rest of the world. Pfizer and BioNTech continue to expect to manufacture 3 billion doses in total by the end of December 2021. The difference between the number of doses expected to contribute to 2021 revenues versus the number of doses expected to be manufactured by year-end relates to anticipated international deliveries in December 2021, which will be recorded as revenue in 2022 due to our international fiscal calendar, and, to a lesser extent, doses expected to be produced but not yet delivered as of December 31, 2021. We anticipate delivering at least two billion doses to low- and middle-income countries by the end of 2022 - at least one billion to be delivered in 2021 and one billion in 2022, with the possibility to increase those deliveries if more orders are placed by these countries for 2022. One billion of these doses will be supplied to the U.S. government at a not-for-profit price to be donated to the world’s poorest nations at no charge to those countries.

•COVID-19 Protease Inhibitors:

◦In July 2021, we initiated the Phase 2/3 EPIC-HR (Evaluation of Protease Inhibition for COVID-19 in High-Risk Patients) study to evaluate the efficacy, safety and tolerability of Paxlovid (PF-07321332; ritonavir), an investigational, novel oral antiviral therapeutic for COVID-19, which is a SARS-CoV2-3CL protease inhibitor and is co-administered with a low dose of ritonavir, in non-hospitalized, high-risk adult participants with COVID-19. In August 2021, we initiated the pivotal Phase 2/3 EPIC-SR (Evaluation of Protease Inhibition for COVID-19 in Standard-Risk Patients) study to evaluate Paxlovid (PF-07321332; ritonavir) in patients with a confirmed diagnosis of SARS-CoV-2 infection who are at standard risk (i.e., low risk of hospitalization or death). In September 2021, we initiated the Phase 2/3 EPIC-PEP (Evaluation of Protease Inhibition for COVID-19 in Post-Exposure Prophylaxis) study to evaluate Paxlovid (PF-07321332; ritonavir) for the prevention of COVID-19 infection in adults living in the same household as someone with a confirmed COVID-19 infection. In November 2021, Pfizer announced the scheduled interim analysis of EPIC-HR, which showed an 89% reduction in risk of COVID-19-related hospitalization or death from any cause compared to placebo in patients treated within three days of symptom onset (primary endpoint). Pfizer plans to submit the data as part of its ongoing rolling submission to the FDA for EUA as soon as possible. We have also entered into agreements to supply pre-specified courses of treatment with several countries and are currently in negotiations with other markets to supply the product, if authorized or approved.

◦In September 2021, the National Institute of Allergy and Infectious Disease initiated a study of our intravenously administered investigational protease inhibitor for COVID-19, PF-07304814, which is a SARS-CoV2-3CL protease inhibitor, in adults hospitalized with COVID-19, as part of the National Institutes of Health’s Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV)-3 program.

Despite our significant investments and efforts, any of our ongoing development programs related to COVID-19 may not be successful as the risk of failure is significant, and there can be no certainty these efforts will yield a successful product or that costs will ultimately be recouped.

Impact of COVID-19 on Our Business and Operations

As part of our on-going monitoring and assessment, we have made certain assumptions regarding the pandemic for purposes of our operational planning and financial projections, including assumptions regarding the duration, severity and the global macroeconomic impact of the pandemic, as well as COVID-19 vaccine supply and contracts, which remain dynamic. Despite careful tracking and planning, we are unable to accurately predict the extent of the impact of the pandemic on our business, operations and financial condition and results due to the uncertainty of future developments. We are focused on all aspects of our business and are implementing measures aimed at mitigating issues where possible, including by using digital technology to assist in operations for our commercial, manufacturing, R&D and corporate enabling functions globally.

As discussed in our 2020 Form 10-K, our business and operations were impacted in 2020 by the pandemic in various ways; certain of those impacts have continued in 2021. For detail on the impact of the COVID-19 pandemic on our products, see the Analysis of the Condensed Consolidated Statements of Income—Revenues by Geography and Revenues—Selected Product Discussion sections within this MD&A. In 2021, engagement with healthcare professionals has started to return to pre-pandemic levels and we continue to review and assess epidemiological data to inform in-person engagements with healthcare professionals and to ensure the safety of our colleagues, customers and communities. As part of our commitment to engaging our customers in the manner they prefer, we are also taking a hybrid approach of virtual and in person engagements and are seeing customer response to both approaches. During the pandemic, we adapted our promotional platform by amplifying our digital capabilities to reach healthcare professionals and customers to provide critical education and information, including increasing the scale of our remote engagement. Also, in 2021, we have continued not to see a significant disruption to our supply chain to date, and all of our manufacturing sites globally have continued to operate at or near normal levels. However, we are seeing an increase in overall demand in the industry for certain components and raw materials potentially constraining available supply, which could have a future impact on our business. We are continuing to monitor and implement mitigation strategies in an effort to reduce any potential impact.

We will continue to pursue efforts to maintain the continuity of our operations while monitoring for new developments related to the pandemic. Future developments could result in additional favorable or unfavorable impacts on our business, operations or financial condition and results. If we experience significant disruption in our manufacturing or supply chains or significant disruptions in clinical trials or other operations, or if demand for our products is significantly reduced as a result of the COVID-19 pandemic, we could experience a material adverse impact on our business, operations and financial condition and results.

For additional information, please see the Item 1A. Risk Factors—COVID-19 Pandemic section and the Overview of Our Performance, Operating Environment, Strategy and Outlook section of the MD&A of our 2020 Form 10-K.

Emerging markets revenues increased $6.9 billion, or 116%, in the first nine months of 2021 to $12.9 billion from $6.0 billion in the first nine months of 2020, reflecting an operational increase of $6.7 billion, or 113%, and a favorable impact from foreign exchange of approximately 3%. The operational increase in emerging markets was primarily driven by revenues from Comirnaty and growth from certain products in the Hospital therapeutic area and Eliquis.

Revenue Deductions

Our gross product revenues are subject to a variety of deductions, which generally are estimated and recorded in the same period that the revenues are recognized. These deductions represent estimates of related obligations and, as such, knowledge and judgment are required when estimating the impact of these revenue deductions on gross sales for a reporting period. Historically, adjustments to these estimates to reflect actual results or updated expectations, have not been material to our overall business and generally have been less than 1% of revenues. Product-specific rebates, however, can have a significant impact on year-over-year individual product revenue growth trends.

The following presents information about revenue deductions:

(a)Being developed in collaboration with BioNTech. Prior to BLA, Comirnaty/BNT162b2 for ages 16 and up was available pursuant to an EUA from the FDA on December 11, 2020. A booster dose received EUA from the FDA on September 22, 2021 for individuals 65 years of age and older, individuals 18 through 64 years of age at high risk of severe COVID-19, and individuals 18 through 64 years of age with frequent institutional or occupational exposure to SARS-CoV-2. In addition, in October 2021, the FDA authorized for emergency use a booster dose to eligible individuals who have completed primary vaccination with a different authorized COVID-19 vaccine. A booster dose received conditional marketing authorization from the EMA on October 5, 2021 and approval in Japan on November 10, 2021 for 18 years of age and older. In November 2021, we and BioNTech submitted a request to the FDA to amend the EUA of a booster dose of Comirnaty/BNT162b2 to include all individuals 18 years of age and older.

(e)In July 2021, the FDA notified the company that it will not meet the PDUFA goal dates for the New Drug Application for abrocitinib and the supplemental New Drug Application for Xeljanz/Xeljanz XR (tofacitinib). The FDA cited its ongoing review of Pfizer's post-marketing safety study, ORAL Surveillance, evaluating tofacitinib in rheumatoid arthritis patients, as a factor for the extensions. In October 2021, the EMA’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending the approval of abrocitinib to treat moderate to severe atopic dermatitis in adults who are candidates for systemic therapy. The CHMP also adopted a positive opinion recommending an extension to the existing indications for Xeljanz (tofacitinib) to include the treatment of adults with active ankylosing spondylitis who have responded inadequately to conventional therapy.

(f)Being developed in collaboration with Myovant.

(g)Being developed in collaboration with OPKO.

(h)In October 2021, the CDC’s ACIP voted to recommend Prevnar 20 for routine use in adults. Specifically, the ACIP voted to recommend the following: (i) adults 65 years of age or older who have not previously received a pneumococcal conjugate vaccine or whose previous vaccination history is unknown should receive a pneumococcal conjugate vaccine

48

(either pneumococcal 20-valent conjugate vaccine (PCV20) or pneumococcal 15-valent conjugate vaccine (PCV15)). If PCV15 is used, this should be followed by a dose of pneumococcal polysaccharide vaccine (PPSV23); and (ii) adults aged 19 years of age or older with certain underlying medical conditions or other risk factors who have not previously received a pneumococcal conjugate vaccine or whose previous vaccination history is unknown should receive a pneumococcal conjugate vaccine (either PCV20 or PCV15). If PCV15 is used, this should be followed by a dose of PPSV23. The recommendations will be forwarded to the director of the CDC and the U.S. Department of Health and Human Services for review and following approval, the recommendations are published in the Morbidity and Mortality Weekly Report.

In October 2021, Pfizer and Lilly discontinued the global clinical development program for tanezumab, an investigational nerve growth factor inhibitor. This decision was made following receipt of a Complete Response Letter from the FDA for the tanezumab application in osteoarthritis (OA) and a negative opinion adopted by the EMA's Committee for Medicinal Products for Human Use on the tanezumab Marketing Authorization Application in OA.

In September 2021, the FDA issued a Drug Safety Communication (DSC) related to Xeljanz/Xeljanz XR and two competitors’ arthritis medicines in the same drug class, based on its completed review of the ORAL Surveillance trial. The DSC stated that the FDA will require revisions to the Boxed Warnings for each of these medicines to include information about the risks of serious heart-related events, cancer, blood clots, and death. In addition, the DSC indicates the FDA’s intention to limit approved uses of these products to certain patients who have not responded or cannot tolerate one or more tumor necrosis factor (TNF) blockers.

Cost of Sales

Cost of sales increased $8.0 billion in the third quarter and $15.5 billion in the first nine months of 2021, primarily due to:

•the impact of Comirnaty, which includes a charge for the 50% gross profit split with BioNTech and applicable royalty expenses;

•increased sales volumes of other products, driven mostly by Pfizer CentreOne; and

•the unfavorable impact of foreign exchange and hedging activity on intercompany inventory.

The increase in Cost of sales as a percentage of revenues in the third quarter of 2021, compared to the same period in 2020, was primarily due to all of the factors discussed above, in addition to the unfavorable impact of the voluntary recall and global pause in shipments of Chantix, partially offset by an increase in alliance revenues, which have no associated cost of sales.

The increase in Cost of sales as a percentage of revenues in the first nine months of 2021, compared to the same period in 2020, was primarily due to all of the factors discussed above, partially offset by an increase in alliance revenues, which have no associated cost of sales.

Selling, Informational and Administrative Expenses

SI&A expenses increased $248 million in the third quarter of 2021, mostly due to:

•an increase in external, incremental costs directly related to implementing our cost-reduction/productivity initiatives; and

•increased product-related spending across multiple therapeutic areas and other costs associated with activity that is closer to pre-pandemic levels as compared to the prior-year quarter.

SI&A expenses increased $759 million in the first nine months of 2021, mostly due to:

•increased product-related spending across multiple therapeutic areas and other costs associated with activity that is closer to pre-pandemic levels as compared to the prior-year period;

•an increase in external, incremental costs directly related to implementing our cost-reduction/productivity initiatives;

•costs related to Comirnaty, driven by a higher provision for healthcare reform fees based on sales;

•the unfavorable impact of foreign exchange; and

•an increase to expense resulting from the increase in our liability to be paid to participants of our supplemental savings plan,

partially offset by:

•lower spending on Chantix following the loss of patent protection in the U.S. in November 2020.

50

Research and Development (R&D) Expenses

R&D expenses increased $1.1 billion in the third quarter primarily due to:

•an upfront payment related to the global collaboration agreement with Arvinas to develop and commercialize ARV-471; and

•increased investments across multiple therapeutic areas, including additional spending related to the development and at-risk manufacturing of the COVID-19 anti-viral programs.

R&D expenses increased $1.9 billion in the first nine months of 2021, primarily due to:

•increased investments across multiple therapeutic areas, including additional spending related to the development and at-risk manufacturing of the COVID-19 anti-viral programs;

•the upfront payment related to the global collaboration agreement with Arvinas to develop and commercialize ARV-471;

•a charge for IPR&D related to an asset acquisition completed in the second quarter of 2021; and

•an increase in the value of the portfolio performance share grants reflecting changes in the price of Pfizer’s common stock, as well as management’s assessment of the probability that the specific performance criteria will be achieved,

partially offset by:

•the non-recurrence of 2020 upfront payments to Valneva and BioNTech; and

•lower spending across the Inflammation & Immunology and Internal medicine portfolios.

Amortization of Intangible Assets

Amortization of intangible assets increased $120 million in the third quarter and $204 million in the first nine months of 2021, primarily as a result of amortization of capitalized Comirnaty sales milestones to BioNTech.

In connection with restructuring our corporate enabling functions, we expect gross cost savings of $1.0 billion, or net cost savings, excluding merit and inflation growth and certain real estate cost increases, of $700 million to be achieved primarily from 2021 through 2022. In connection with transforming our marketing strategy, we expect net cost savings of $1.3 billion, to be achieved primarily from 2022 through 2024. In connection with manufacturing network optimization, including legacy cost reduction initiatives, we expect net cost savings of $300 million to be achieved primarily from 2020 through 2022.

Certain qualifying costs for this program were recorded in the first three quarters of 2021 and 2020 and are reflected as Certain Significant Items and excluded from our non-GAAP measure of Adjusted Income. See the Non-GAAP Financial Measure: Adjusted Income section of this MD&A.

In addition to this program, we continuously monitor our operations for cost reduction and/or productivity opportunities, especially in light of the losses of exclusivity and the expiration of collaborative arrangements for various products.

Other (Income)/Deductions—Net

Other income—net increased $3.6 billion in the third quarter of 2021, mainly due to:

•net periodic benefit credits recorded in the third quarter of 2021 versus net periodic benefit costs recorded in the third quarter of 2020;

•the non-recurrence of certain asset impairment charges that were incurred in the third quarter of 2020; and

•net gains on equity securities in the third quarter of 2021 versus net losses on equity securities recognized in the third quarter of 2020.

Other income—net increased $4.8 billion in the first nine months of 2021, mainly due to:

•net periodic benefit credits recorded in the first nine months of 2021 versus net periodic benefit costs recorded in the first nine months of 2020;

•higher net gains on equity securities; and

•the non-recurrence of certain asset impairment charges that were incurred in the first nine months of 2020.

NON-GAAP FINANCIAL MEASURE: ADJUSTED INCOME

Adjusted income is an alternative measure of performance used by management to evaluate our overall performance in conjunction with other performance measures. As such, we believe that investors’ understanding of our performance is enhanced by disclosing this measure. We use Adjusted income, certain components of Adjusted income and Adjusted diluted EPS to present the results of our major operations––the discovery, development, manufacture, marketing, sale and distribution of biopharmaceutical products worldwide––prior to considering certain income statement elements as follows:

Measure	Definition	Illustrative Use
Adjusted income	Net income attributable to Pfizer Inc. common shareholders(a) before the impact of purchase accounting for acquisitions, acquisition-related items, discontinued operations and certain significant items	•Monthly managerial analysis of our operating results and our annual budgets are prepared using these non-GAAP measures •Senior management’s compensation is determined, in part, using these non-GAAP measures(b)
Adjusted cost of sales, Adjusted selling, informational and administrative expenses, Adjusted research and development expenses, Adjusted amortization of intangible assets and Adjusted other (income)/deductions––net	Cost of sales, Selling, informational and administrative expenses, Research and development expenses, Amortization of intangible assets and Other (income)/deductions––net (a), each before the impact of purchase accounting for acquisitions, acquisition-related items, discontinued operations and certain significant items, which are components of the Adjusted income measure
Adjusted diluted EPS	EPS attributable to Pfizer Inc. common shareholders––diluted(a) before the impact of purchase accounting for acquisitions, acquisition-related items, discontinued operations and certain significant items

(a)Most directly comparable GAAP measure.

(b)The short-term incentive plans for substantially all non-sales-force employees worldwide are funded from a pool based on our performance, measured in significant part by three metrics, one of which is Adjusted diluted EPS, which is derived from Adjusted income and accounts for 40% of the bonus pool funding. Additionally, the payout for Performance Share Awards is determined in part by Adjusted net income, which is derived from Adjusted income. Starting with the 2020 performance year and consistent with shareholder feedback received in 2019, the Compensation Committee of the BOD approved adding an R&D pipeline achievement factor to the existing short-term incentive financial metrics.

Adjusted income and its components and Adjusted diluted EPS are non-GAAP financial measures that have no standardized meaning prescribed by GAAP and, therefore, are limited in their usefulness to investors. Because of their non-standardized definitions, they may not be comparable to the calculation of similar measures of other companies and are presented solely to permit investors to more fully understand how management assesses performance. A limitation of these measures is that they provide a view of our operations without including all events during a period, and do not provide a comparable view of our performance to peers. These measures are not, and should not be viewed as, substitutes for their directly comparable GAAP measures of Net income attributable to Pfizer Inc. common shareholders, components of Net income attributable to Pfizer Inc. common shareholders and EPS attributable to Pfizer Inc. common shareholders—diluted, respectively. See the accompanying reconciliations of certain GAAP reported to non-GAAP adjusted information for the third quarter and first nine months of 2021 and 2020 below.

We also recognize that, as internal measures of performance, these measures have limitations, and we do not restrict our performance-management process solely to these measures. We also use other tools designed to achieve the highest levels of performance. For example, our R&D organization has productivity targets, upon which its effectiveness is measured. In

addition, total shareholder return, both on an absolute basis and relative to a publicly traded pharmaceutical index, plays a significant role in determining payouts under certain of our incentive compensation plans.

Purchase Accounting Adjustments

Adjusted income excludes certain significant purchase accounting impacts resulting from business combinations and net asset acquisitions. These impacts can include the incremental charge to cost of sales from the sale of acquired inventory that was written up to fair value, amortization related to the increase in fair value of the acquired finite-lived intangible assets, and to a much lesser extent, depreciation related to the increase/decrease in fair value of the acquired fixed assets, amortization related to the increase in fair value of acquired debt, and the fair value changes for contingent consideration. Therefore, the Adjusted income measure includes the revenues earned upon the sale of the acquired products without considering the acquisition cost of those products.

Acquisition-Related Items

Adjusted income excludes acquisition-related items, which are comprised of transaction, integration, restructuring charges and additional depreciation costs for business combinations because these costs are unique to each transaction and represent costs that were incurred to restructure and integrate businesses as a result of an acquisition. We have made no adjustments for resulting synergies.

Discontinued Operations

Adjusted income excludes the results of discontinued operations, as well as any related gains or losses on the disposal of such operations. We believe that this presentation is meaningful to investors because, while we review our therapeutic areas and product lines for strategic fit with our operations, we do not build or run our business with the intent to discontinue parts of our business. Restatements due to discontinued operations do not impact compensation or change the Adjusted income measure for the compensation in respect of the restated periods, but are presented for consistency across all periods.

Certain Significant Items

Adjusted income excludes certain significant items representing substantive and/or unusual items that are evaluated individually on a quantitative and qualitative basis. Certain significant items may be highly variable and difficult to predict. Furthermore, in some cases it is reasonably possible that they could reoccur in future periods. For example, although major non-acquisition-related cost-reduction/productivity programs are specific to an event or goal with a defined term, we may have subsequent programs based on reorganizations of the business, cost-reduction/productivity or in response to LOE or economic conditions. Legal charges to resolve litigation are also related to specific cases, which are facts and circumstances specific and, in some cases, may also be the result of litigation matters at acquired companies that were inestimable, not probable or unresolved at the date of acquisition. Unusual items represent items that are not part of our ongoing business; items that, either as a result of their nature or size, we would not expect to occur as part of our normal business on a regular basis; items that would be non-recurring; or items that relate to products we no longer sell. For a non-inclusive list of certain significant items see Details of Income Statement Items Included in GAAP Reported but Excluded from Non-GAAP Adjusted Income below.

Beginning in 2021, we exclude pension and postretirement actuarial remeasurement gains and losses from our measure of Adjusted income because of their inherent market volatility, which we do not control and cannot predict with any level of certainty and because we do not believe including these gains and losses assists investors in understanding our business or is reflective of our core operations and business.

Also, see the Non-GAAP Financial Measure: Adjusted Income section of the MD&A of our 2020 Form 10-K for additional information.

ANALYSIS OF THE CONDENSED CONSOLIDATED STATEMENTS OF CASH FLOWS

Cash Flows from Continuing Operations

	Nine Months Ended
(MILLIONS)	October 3, 2021		September 27, 2020		Drivers of change
Cash provided by/(used in):
Operating activities from continuing operations	$	26,660	$	6,364	The change is driven primarily by higher net income and advance payments in 2021 for Comirnaty recorded in deferred revenue and the impact of timing of receipts and payments in the ordinary course of business, including a $7.8 billion accrual for the gross profit split due to BioNTech, partially offset by a non-cash change in Other Adjustments, net, primarily resulting from an increase in unrealized gains on equity securities.
Investing activities from continuing operations	$	(19,960)	$	(1,129)	The change is driven mainly by a $17.0 billion increase in purchases of short-term investments with original maturities of greater than three months and a $7.8 billion increase in net purchases of short-term investments with original maturities of three months or less, partially offset by a $7.5 billion increase in redemptions of short-term investments with original maturities of greater than three months.
Financing activities from continuing operations	$	(6,465)	$	(7,257)	The change is driven mostly by a $5.1 billion net reduction in repayments of short-term borrowings with maturities of greater than three months and a $1.5 billion reduction in repayments of long-term debt, partially offset by a $4.2 billion decrease in proceeds from issuances of long-term debt and a $1.4 billion net decrease in proceeds from short-term borrowings with maturities of three months or less.

Cash Flows from Discontinued Operations

Cash flows from discontinued operations primarily relate to our former Upjohn Business and the Mylan-Japan collaboration (see Note 2A). In 2020, investing and financing activities from discontinued operations primarily reflect investments in money market funds with proceeds from issuances of long-term debt.

ANALYSIS OF FINANCIAL CONDITION, LIQUIDITY, CAPITAL RESOURCES AND MARKET RISK

We rely largely on operating cash flows, short-term investments or commercial paper borrowings and long-term debt to provide for our liquidity requirements. We strive to improve cash inflows through working capital efficiencies. Due to our significant operating cash flows as well as our financial assets, access to capital markets and available lines of credit and revolving credit agreements, we believe that we have, and will maintain, the ability to meet our liquidity needs for the foreseeable future. We have taken and will continue to take a conservative approach to our financial investments and monitoring of our liquidity position in response to market changes. Our debt investments consist primarily of high-quality, highly liquid, well-diversified available-for-sale debt securities.

Debt Capacity––Lines of Credit

We have available lines of credit and revolving credit agreements with a group of banks and other financial intermediaries. We typically maintain cash and cash equivalent balances and short-term investments which, together with our available revolving credit facilities, are in excess of our commercial paper and other short-term borrowings. As of October 3, 2021, we had access to a $7 billion U.S. revolving credit facility expiring in 2025. In addition, our lenders have provided us an additional $377 million in lines of credit, of which $336 million expire within one year. Essentially all lines of credit were unused as of October 3, 2021.

(a)See Note 7 for a description of certain assets held and for a description of credit risk related to our financial instruments held.

(b)The increase in working capital was primarily driven by an increase in short-term investments due to operating cash flow generation, partially offset by the timing of accruals, cash receipts and payments in the ordinary course of business and capital expenditures.

In August 2021, we completed a public offering of $1 billion aggregate principal amount of senior unsecured sustainability notes. We are using the net proceeds to finance or refinance, in whole or in part as follows: R&D expenses related to our COVID-19 vaccine, capital expenditures in connection with the manufacture and distribution of COVID-19 vaccines and other projects that have environmental and/or social benefits. For additional information, see Note 7D.

For information about the sources and uses of our funds, see the Analysis of the Condensed Consolidated Statements of Cash Flows section within MD&A.

For information about credit ratings, LIBOR, global economic conditions, and market risk, see the Analysis of Financial Condition, Liquidity, Capital Resources and Market Risk—Selected Measures of Liquidity and Capital Resources section within MD&A in our 2020 Form 10-K.

Off-Balance Sheet Arrangements

In the ordinary course of business and in connection with the sale of assets and businesses and other transactions, we often indemnify our counterparties against certain liabilities that may arise in connection with the transaction or that are related to events and activities. For more information on guarantees and indemnifications, see Note 12B.

Additionally, certain of our co-promotion or license agreements give our licensors or partners the rights to negotiate for, or in some cases to obtain under certain financial conditions, co-promotion or other rights in specified countries with respect to certain of our products.

Share-Purchase Plans and Accelerated Share Repurchase Agreements

At October 3, 2021, our remaining share-purchase authorization was approximately $5.3 billion, with no repurchases in the first nine months of 2021. See Note 12 in our 2020 Form 10-K for more information on our publicly announced share-purchase plans.

Dividends on Common Stock

In September 2021, our BOD declared a dividend of $0.39 per share, payable on December 6, 2021, to shareholders of record at the close of business on November 5, 2021. Our current and projected dividends provide a return to shareholders while maintaining sufficient capital to invest in growing our business. Our dividends are not restricted by debt covenants. While the dividend level remains a decision of Pfizer’s BOD and will continue to be evaluated in the context of future business performance, we currently believe that we can support future annual dividend increases, barring significant unforeseen events.

NEW ACCOUNTING STANDARDS

Recently Adopted Accounting Standard

See Note 1B.

Recently Issued Accounting Standard, Not Adopted as of October 3, 2021
Standard/Description	Effective Date	Effect on the Financial Statements
Reference rate reform provides temporary optional expedients and exceptions to the guidance for contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued after 2021 because of reference rate reform. The new guidance provides the following optional expedients: 1.Simplify accounting analyses under current U.S. GAAP for contract modifications. 2.Simplify the assessment of hedge effectiveness and allow hedging relationships affected by reference rate reform to continue. 3.Allow a one-time election to sell or transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform.	Elections can be adopted prospectively at any time through December 31, 2022.	We are assessing the impact of the provisions of this new guidance on our consolidated financial statements.
Accounting for contract assets and contract liabilities from contracts with customers requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606. This new guidance will generally result in the acquirer recognizing contract assets and contract liabilities at the same amounts that were recorded by the acquiree. Previously, these amounts were recognized by the acquirer at fair value as of the acquisition date.	January 1, 2023. Early adoption is permitted.	We do not expect this new guidance to have a material impact on our consolidated financial statements.

FORWARD-LOOKING INFORMATION AND FACTORS THAT MAY AFFECT FUTURE RESULTS

This Form 10-Q contains forward-looking statements. We also provide forward-looking statements in other materials we release to the public, as well as public oral statements. Given their forward-looking nature, these statements involve substantial risks, uncertainties and potentially inaccurate assumptions.

We have tried, wherever possible, to identify such statements by using words such as “will,” “may,” “could,” “likely,” “ongoing,” “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “assume,” “target,” “forecast,” “guidance,” “goal,” “objective,” “aim,” “seek” and other words and terms of similar meaning or by using future dates.

We include forward-looking information in our discussion of the following, among other topics:

•our anticipated operating and financial performance, reorganizations, business plans and prospects;

•expectations for our product pipeline, in-line products and product candidates, including anticipated regulatory submissions, data read-outs, study starts, approvals, clinical trial results and other developing data, revenue contribution, growth, performance, timing of exclusivity and potential benefits;

•strategic reviews, capital allocation objectives, dividends and share repurchases;

•plans for and prospects of our acquisitions, dispositions and other business development activities, and our ability to successfully capitalize on these opportunities;

•sales, expenses, interest rates, foreign exchange rates and the outcome of contingencies, such as legal proceedings;

•expectations for impact of or changes to existing or new government regulations or laws;

59

•our ability to anticipate and respond to macroeconomic, geopolitical, health and industry trends, pandemics, acts of war and other large-scale crises; and

•manufacturing and product supply.

In particular, forward-looking information in this Form 10-Q includes statements relating to specific future actions and effects, including, among others, our efforts to respond to COVID-19, including our development of a vaccine to help prevent COVID-19 and our investigational protease inhibitors, the forecasted revenue contribution of Comirnaty and the potential number of doses that we and BioNTech believe can be manufactured; our expectations regarding the impact of COVID-19 on our business; the expected impact of patent expiries and competition from generic manufacturers; the benefits expected from our business development transactions; our anticipated liquidity position; the anticipated costs and savings from certain of our initiatives, including our Transforming to a More Focused Company program; anticipated study starts; our planned capital spending; and the expectations for our quarterly dividend payments.

Given their nature, we cannot assure that any outcome expressed in these forward-looking statements will be realized in whole or in part. Actual outcomes may vary materially from past results and those anticipated, estimated, implied or projected. These forward-looking statements may be affected by underlying assumptions that may prove inaccurate or incomplete, or by known or unknown risks and uncertainties, including those described in this section and in the Item 1A. Risk Factors section in our 2020 Form 10-K.

Therefore, you are cautioned not to unduly rely on forward-looking statements, which speak only as of the date of this Form 10-Q. We undertake no obligation to update forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable securities law. You are advised, however, to consult any further disclosures we make on related subjects.

Some of the factors that could cause actual results to differ are identified below, as well as those discussed in the Item 1A. Risk Factors section in our 2020 Form 10-K and within this MD&A. We note these factors for investors as permitted by the Private Securities Litigation Reform Act of 1995. The occurrence of any of the risks identified below or in the Item 1A. Risk Factors section in our 2020 Form 10-K, or other risks currently unknown, could have a material adverse effect on our business, financial condition or results of operations, or we may be required to increase our accruals for contingencies. It is not possible to predict or identify all such factors. Consequently, you should not consider the following to be a complete discussion of all potential risks or uncertainties:

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Information required by this item is incorporated by reference from the discussion in the Analysis of Financial Condition, Liquidity, Capital Resources and Market Risk—Selected Measures of Liquidity and Capital Resources—Market Risk section within MD&A of our 2020 Form 10-K.

ITEM 4. CONTROLS AND PROCEDURES

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures are effective in alerting them in a timely manner to material information required to be disclosed in our periodic reports filed with the SEC.

During our most recent fiscal quarter, there has not been any change in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation and Significant Accounting Policies

Basis of Presentation and Significant Accounting Policies

A. Basis of Presentation

We prepared these condensed consolidated financial statements in conformity with U.S. GAAP, consistent in all material respects with those applied in our 2020 Form 10-K, except as disclosed in Note 1C. As permitted under the SEC requirements for interim reporting, certain footnotes or other financial information have been condensed or omitted.

These financial statements include all normal and recurring adjustments that are considered necessary for the fair statement of results for the interim periods presented. The information included in this Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our 2020 Form 10-K. Revenues, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be representative of those for the full year.

Pfizer’s fiscal quarter-end for subsidiaries operating outside the U.S. is as of and for the three and nine months ended August 29, 2021 and August 23, 2020, and for U.S. subsidiaries is as of and for the three and nine months ended October 3, 2021 and September 27, 2020.

Business development activities impacted financial results in the periods presented. See Note 1A in our 2020 Form 10-K, and Note 2. On November 16, 2020, we completed the spin-off and the combination of our Upjohn Business with Mylan to form Viatris. For additional information, see Note 2B in our 2020 Form 10-K. On December 21, 2020, which fell in Pfizer’s international first quarter of 2021, Pfizer and Viatris completed the termination of the Mylan-Japan collaboration pursuant to an agreement dated November 13, 2020, and we transferred related inventories and operations that were part of the Mylan-Japan collaboration to Viatris. As a result, the financial position and results of operations of the Upjohn Business and the Mylan-Japan collaboration are presented as discontinued operations. Prior-period information has been restated to reflect our current organization structure.

B. New Accounting Standard Adopted in 2021

On January 1, 2021, we adopted a new accounting standard for income tax that eliminates certain exceptions to the guidance related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The adoption of this guidance did not have a material impact on our condensed consolidated financial statements.

For information on new accounting standards adopted in 2020, see Note 1B in our 2020 Form 10-K.

C. Change in Accounting Principle

In the first quarter of 2021, we adopted a change in accounting principle to a more preferable policy under U.S. GAAP to immediately recognize actuarial gains and losses arising from the remeasurement of our pension and postretirement plans (MTM Accounting). Under the prior policy, we deferred recognition of these gains and losses in Accumulated other comprehensive loss. The accumulated actuarial gains/losses outside of a “corridor” were then amortized into net periodic benefit costs over the average remaining service period or the average life expectancy of participants. This change has been applied to all pension and postretirement plans on a retrospective basis for all prior periods presented, and as of January 1, 2020, resulted in a cumulative effect decrease to Retained earnings of $6.3 billion, with a corresponding offset to Accumulated other comprehensive loss. Each time a pension or postretirement plan is remeasured, the actuarial gain or loss is recognized immediately and classified as Other (income)/deductions––net.

We believe that MTM Accounting is a more preferable policy as it provides improved transparency of results and performance, better alignment with fair value accounting principles and a better reflection of current economic and interest rate trends on plan investments and assumptions and the actuarial impact of plan remeasurements.

The impacts of the adjustments on our condensed consolidated financial statements are summarized as follows:

D. Revenues and Trade Accounts Receivable

Customers––Our prescription pharmaceutical products are sold principally to wholesalers, but we also sell directly to retailers, hospitals, clinics, government agencies and pharmacies. In the U.S., we primarily sell our vaccine products directly to the federal government, CDC, wholesalers, individual provider offices, retail pharmacies and integrated delivery networks. Outside the U.S., we primarily sell our vaccines to government and non-government institutions.

Deductions from Revenues––Our accruals for Medicare, Medicaid and related state program and performance-based contract rebates, chargebacks, sales allowances and sales returns and cash discounts are as follows:

(MILLIONS)	October 3, 2021		December 31, 2020
Reserve against Trade accounts receivable, less allowance for doubtful accounts	$	996	$	861
Other current liabilities:
Accrued rebates	3,470		3,017
Other accruals	470		436
Other noncurrent liabilities	503		399
Total accrued rebates and other sales-related accruals	$	5,439	$	4,712

Trade Accounts Receivable––Trade accounts receivable are stated at their net realizable value. The allowance for credit losses reflects our best estimate of expected credit losses of the receivables portfolio determined on the basis of historical experience, current information, and forecasts of future economic conditions. In developing the estimate for expected credit losses, trade accounts receivables are segmented into pools of assets depending on market (U.S. versus international), delinquency status, and customer type (high risk versus low risk and government versus non-government), and fixed reserve percentages are established for each pool of trade accounts receivables.

In determining the reserve percentages for each pool of trade accounts receivables, we considered our historical experience with certain customers and customer types, regulatory and legal environments, country and political risk, and other relevant current and future forecasted macroeconomic factors. These credit risk indicators are monitored on a quarterly basis to determine whether there have been any changes in the economic environment that would indicate the established reserve percentages should be adjusted, and are considered on a regional basis to reflect more geographic-specific metrics. Additionally, write-offs and recoveries of customer receivables are tracked against collections on a quarterly basis to determine whether the reserve percentages remain appropriate. When management becomes aware of certain customer-specific factors that impact credit risk,

specific allowances for these known troubled accounts are recorded. Trade accounts receivable are written off after all reasonable means to collect the full amount (including litigation, where appropriate) have been exhausted.

During the three and nine months ended October 3, 2021 and September 27, 2020, additions to the allowance for credit losses, write-offs and recoveries of customer receivables were not material to our condensed consolidated financial statements. For additional information on our trade accounts receivable, see Note 1G in our 2020 Form 10-K.

Discontinued Operations, Equity-Method Investment and Collaborative Arrangement

Discontinued Operations, Equity-Method Investment and Collaborative Arrangement

A. Discontinued Operations

Upjohn Separation and Combination with Mylan

On November 16, 2020, we completed the spin-off and the combination of the Upjohn Business with Mylan to form Viatris. See Note 1A.

In connection with this transaction, Pfizer and Viatris entered into various agreements to effect the separation and combination to provide a framework for our relationship after the combination, including a separation and distribution agreement, interim operating models, including agency arrangements, manufacturing and supply agreements (MSAs), transition service agreements (TSAs), a tax matters agreement, and an employee matters agreement, among others. The interim agency operating model arrangements primarily include billings, collections and remittance of rebates that we are performing on a transitional basis on behalf of Viatris. Under the MSAs, Pfizer or Viatris, as the case may be, manufactures, labels and packages products for the other party. In the three and nine months ended October 3, 2021, the amounts recorded under the above agreements were not material to our consolidated results of operations. Net amounts due from Viatris under the above agreements were approximately $197 million as of October 3, 2021 and $401 million as of December 31, 2020. The cash flows associated with the above agreements are included in Net cash provided by operating activities from continuing operations, except for a $277 million payment to Viatris made in the first quarter of 2021 pursuant to terms of the separation agreement, which is reported in Other financing activities, net, and was recorded as a payable to Viatris in Other current liabilities as of December 31, 2020. In addition, Pfizer and Mylan had pre-existing arms-length commercial agreements, which are continuing with Viatris and are not material to Pfizer’s consolidated financial statements.

The operating results of the Upjohn Business and the Mylan-Japan collaboration are reported as Income/(loss) from discontinued operations––net of tax.

Components of Income/(loss) from discontinued operations––net of tax:

(a)In the third quarter of 2021, Income/(loss) from discontinued operations—net of tax reflects post-closing adjustments directly related to our discontinued operations, including adjustments for legal and tax related matters. In the first nine months of 2021, Income/(loss) from discontinued operations—net of tax includes the operations of the Mylan-Japan collaboration, which terminated during Pfizer’s international first quarter of 2021, and post-closing adjustments directly related to our discontinued operations, including adjustments for tax, benefits and legal related matters. In the three and nine months ended September 27, 2020, Income/(loss) from discontinued operations—net of tax relates to the Upjohn Business and the Mylan-Japan collaboration and includes the change in accounting principle in the first quarter of 2021 to MTM Accounting, which has been applied on a retrospective basis for all prior periods presented. See Note 1C. In the three and nine months ended September 27, 2020, Income/(loss) from discontinued operations—net of tax includes interest expense of $76 million associated with the U.S. dollar and Euro denominated senior unsecured notes issued by Upjohn Inc. and Upjohn Finance B.V. in the second quarter of 2020 and charges of $144 million related to the remeasurement of Euro debt issued by Upjohn Finance B.V. in the second quarter of 2020.

B. Equity-Method Investment

Formation of Consumer Healthcare JV

On July 31, 2019, we completed a transaction in which we and GSK combined our respective consumer healthcare businesses into a new JV that operates globally under the GSK Consumer Healthcare name. In exchange, we received a 32% equity stake in the new company and GSK owns the remaining 68%.

We are accounting for our interest in the Consumer Healthcare JV as an equity-method investment. The carrying value of our investment in the Consumer Healthcare JV is $16.1 billion as of October 3, 2021 and $16.7 billion as of December 31, 2020 and is reported as a private equity investment in Equity-method investments as of October 3, 2021 and December 31, 2020. The Consumer Healthcare JV is a foreign investee whose reporting currency is the U.K. pound, and therefore we translate its financial statements into U.S. dollars and recognize the impact of foreign currency translation adjustments in the carrying value of our investment and in other comprehensive income. The decrease in the value of our investment from December 31, 2020 is primarily due to $549 million in pre-tax foreign currency translation adjustments (see Note 6), as well as dividends totaling approximately $295 million, partially offset by our share of the JV’s earnings. We record our share of earnings from the Consumer Healthcare JV on a quarterly basis on a one-quarter lag in Other (income)/deductions––net. Our total share of the JV’s earnings generated in the second quarter of 2021, which we recorded in our operating results in the third quarter of 2021, was $106 million. Our total share of the JV’s earnings generated in the fourth quarter of 2020 and first six months of 2021, which we recorded in our operating results in the first nine months of 2021, was $324 million. Our total share of the JV’s earnings generated in the second quarter of 2020, which we recorded in our operating results in the third quarter of 2020, was $166 million. Our total share of the JV’s earnings generated in the fourth quarter of 2019 and first six months of 2020, which we recorded in our operating results in the first nine months of 2020, was $306 million. The total amortization and adjustment of basis differences resulting from the excess of the initial fair value of our investment over the underlying equity in the carrying value of the net assets of the JV is included in Other (income)/deductions––net and was not material to our results of operations in the periods presented. See Note 4.

Summarized financial information for our equity method investee, the Consumer Healthcare JV, for the three and nine months ending June 30, 2021, the most recent period available, and for the three and nine months ending June 30, 2020, is as follows:
	Three Months Ended				Nine Months Ended
(MILLIONS)	June 30, 2021		June 30, 2020		June 30, 2021		June 30, 2020

Net income	348		524		1,064		995
Income attributable to shareholders	330		518		1,012		959

C. Collaboration Arrangement

Collaboration with Arvinas

On July 22, 2021, we announced a global collaboration with Arvinas to develop and commercialize ARV-471, an investigational oral PROTAC® (PROteolysis TArgeting Chimera) estrogen receptor protein degrader. The estrogen receptor is a well-known disease driver in most breast cancers. Under the terms of the collaboration agreement, we made an upfront payment to Arvinas of $650 million in July 2021, which was recorded to Research and development expenses. On September 13, 2021, we made a $350 million equity investment in Arvinas, receiving approximately 3.5 million newly issued shares of Arvinas common stock, priced at a 30% premium to the 30-day volume weighted average price on July 20, 2021, representing an equity ownership stake by Pfizer of approximately 7% as of September 13, 2021. Arvinas is also eligible to receive up to $400 million in approval milestones and up to $1 billion in commercial milestones. The companies will equally share worldwide development costs, commercialization expenses and profits.

Restructuring and Related Activities [Abstract]

Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiatives

Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiatives

A. Transforming to a More Focused Company Program

With the formation of the Consumer Healthcare JV in 2019 and the spin-off of our Upjohn Business in the fourth quarter of 2020, Pfizer has transformed into a focused, global leader in science-based innovative medicines and vaccines. We have

undertaken efforts to ensure our cost base and support model align appropriately with our new operating structure. While certain direct costs transferred to the Consumer Healthcare JV and to the Upjohn Business in connection with the spin-off, there are indirect costs which did not transfer. This program is primarily composed of the following three initiatives:

•We are taking steps to restructure our corporate enabling functions to appropriately support our business, R&D and PGS platform functions. We expect costs, primarily related to restructuring our corporate enabling functions, to total $1.6 billion, with substantially all costs to be cash expenditures. Actions include, among others, changes in location of certain activities, expanded use and co-location of centers of excellence and shared services, and increased use of digital technologies. The associated actions and the specific costs will primarily include severance and benefit plan impacts, exit costs as well as associated implementation costs.

•In addition, we are transforming our commercial go-to market model in the way we engage patients and physicians. We expect costs of $1.1 billion, with substantially all costs to be cash expenditures. Actions include, among others, centralization of certain activities and enhanced use of digital technologies. The costs for this effort primarily include severance and associated implementation costs.

•We are also optimizing our manufacturing network and incurring certain legacy cost-reduction initiatives related to our manufacturing business. We expect to incur costs of $500 million, with approximately 20% of the costs to be non-cash. The costs for this effort include, among other things, implementation costs, product transfer costs, site exit costs, as well as accelerated depreciation.

The program costs discussed above are expected to be incurred primarily from 2020 through 2022, and may be rounded and represent approximations.

From the start of this program in the fourth quarter of 2019 through October 3, 2021, we incurred costs of $2.0 billion.

Income Tax Disclosure [Abstract]

Tax Matters

Tax Matters

A. Taxes on Income from Continuing Operations

Our effective tax rate for continuing operations was (4.2)% for the third quarter of 2021, compared to (60.9)% for the third quarter of 2020, and was 7.5% for the first nine months of 2021, compared to 6.7% for the first nine months of 2020.

The negative effective tax rate for the third quarter of 2021 was primarily a result of certain initiatives executed in the third quarter of 2021 associated with our investment in the Consumer Healthcare JV with GSK based on estimates and assumptions

that we believe to be reasonable. The negative effective tax rate for the third quarter of 2020 was primarily a result of benefits associated with certain intangible asset impairments (see Note 4(e)). The increase in the effective tax rate for the first nine months of 2021, compared to the first nine months of 2020, was due to the change in the jurisdictional mix of earnings primarily related to Comirnaty and the non-recurrence of benefits associated with certain intangible asset impairments, partially offset by certain initiatives executed in the third quarter of 2021 associated with our investment in the Consumer Healthcare JV with GSK.

We elected, with the filing of our 2018 U.S. Federal Consolidated Income Tax Return, to pay our initial estimated $15 billion repatriation tax liability on accumulated post-1986 foreign earnings over eight years through 2026. The third annual installment of this liability was paid by its April 15, 2021 due date. The fourth annual installment is due April 15, 2022 and is reported in current Income taxes payable as of October 3, 2021. The remaining liability is reported in noncurrent Other taxes payable. Our obligations may vary as a result of changes in our uncertain tax positions and/or availability of attributes such as foreign tax and other credit carryforwards.

B. Tax Contingencies

We are subject to income tax in many jurisdictions, and a certain degree of estimation is required in recording the assets and liabilities related to income taxes. All of our tax positions are subject to audit by the local taxing authorities in each tax jurisdiction. These tax audits can involve complex issues, interpretations and judgments and the resolution of matters may span multiple years, particularly if subject to negotiation or litigation.

The U.S. is one of our major tax jurisdictions, and we are regularly audited by the IRS. With respect to Pfizer, the IRS has issued Revenue Agent’s Reports (RARs) for tax years 2011-2013 and 2014-2015. We are not in agreement with the RARs and are currently appealing certain disputed issues. Tax years 2016-2018 are currently under audit. Tax years 2019-2021 are open but not under audit. All other tax years are closed. In addition to the open audit years in the U.S., we have open audit years in certain major international tax jurisdictions dating back to 2011.

For additional information, see Note 5D in our 2020 Form 10-K.

E. Derivative Financial Instruments and Hedging Activities

Foreign Exchange Risk

A significant portion of our revenues, earnings and net investments in foreign affiliates is exposed to changes in foreign exchange rates. We manage our foreign exchange risk principally through the use of derivative financial instruments and

foreign currency debt. These financial instruments serve to mitigate the impact on net income as a result of remeasurement into another currency, or against the impact of translation into U.S. dollars of certain foreign exchange-denominated transactions.

The derivative financial instruments primarily hedge or offset exposures in the euro, U.K. pound, Japanese yen and Canadian dollar. We hedge a portion of our forecasted intercompany inventory sales denominated in euro, Japanese yen, Canadian dollar, Chinese renminbi, U.K. pound and Australian dollar for up to two years.

Interest Rate Risk

Our interest-bearing investments and borrowings are subject to interest rate risk. Depending on market conditions, we may change the profile of our outstanding debt or investments by entering into derivative financial instruments like interest rate swaps, either to hedge or offset the exposure to changes in the fair value of hedged items with fixed interest rates, or to convert variable rate debt or investments to fixed rates. The derivative financial instruments primarily hedge U.S. dollar fixed-rate debt.

The following summarizes the fair value of the derivative financial instruments and notional amounts (including those reported as part of discontinued operations):
	October 3, 2021						December 31, 2020
			Fair Value						Fair Value

(a)OID = Other (income)/deductions—net, included in Other (income)/deductions—net in the condensed consolidated statements of income. COS = Cost of Sales, included in Cost of sales in the condensed consolidated statements of income. OCI = Other comprehensive income/(loss), included in the condensed consolidated statements of comprehensive income.

(b)The amounts reclassified from OCI into COS were:

•a net loss of $18 million in the third quarter of 2021;

•a net loss of $94 million in the first nine months of 2021;

•a net gain of $34 million in the third quarter of 2020; and

•a net gain of $184 million in the first nine months of 2020.

The remaining amounts were reclassified from OCI into OID. Based on quarter-end foreign exchange rates that are subject to change, we expect to reclassify a pre-tax gain of $202 million within the next 12 months into income. The maximum length of time over which we are hedging our exposure to the variability in future foreign exchange cash flows is approximately 22 years and relates to foreign currency debt.

(c)The amounts reclassified from OCI were reclassified into OID.

(d)Short-term borrowings and long-term debt include foreign currency borrowings which are used in net investment hedges. The short-term borrowings carrying value as of October 3, 2021 was $1.2 billion. The long-term debt carrying values as of October 3, 2021 and December 31, 2020 were $862 million and $2.1 billion, respectively.

The following summarizes cumulative basis adjustments for fair value hedges to our long-term debt:
	October 3, 2021						December 31, 2020

(MILLIONS)	Carrying Amount of Hedged Assets/Liabilities(a)		Active Hedging Relationships		Discontinued Hedging Relationships		Carrying Amount of Hedged Assets/Liabilities(a)		Active Hedging Relationships		Discontinued Hedging Relationships
Long-term debt	$	1,241	$	18	$	1,178	$	2,016	$	117	$	1,149

(a)Carrying amounts exclude the cumulative amount of fair value hedging adjustments.

F. Credit Risk

A significant portion of our trade accounts receivable balances are due from wholesalers and governments. For additional information on our trade accounts receivables with significant customers, see Note 13B below and Note 17B in our 2020 Form 10-K.

As of October 3, 2021, the largest investment exposures in our portfolio represent primarily sovereign debt instruments issued by the U.S., Canada, Germany, Japan, U.K., France, Australia, Sweden, Denmark, Switzerland, and Finland.

With respect to our derivative financial instrument agreements with financial institutions, we do not expect to incur a significant loss from failure of any counterparty. Derivative financial instruments are executed under International Swaps and Derivatives Association (ISDA) master agreements with credit-support annexes that contain zero threshold provisions requiring collateral to be exchanged daily depending on levels of exposure. As a result, there are no significant concentrations of credit risk with any individual financial institution. As of October 3, 2021, the aggregate fair value of these derivative financial instruments that are in a net payable position was $357 million, for which we have posted collateral of $357 million with a corresponding amount reported in Short-term investments. As of October 3, 2021, the aggregate fair value of our derivative financial instruments that are in a net receivable position was $246 million, for which we have received collateral of $236 million with a corresponding amount reported in Short-term borrowings, including current portion of long-term debt.

Commitments and Contingencies Disclosure [Abstract]

Contingencies and Certain Commitments

Contingencies and Certain Commitments

We and certain of our subsidiaries are subject to numerous contingencies arising in the ordinary course of business, including tax and legal contingencies. The following outlines our legal contingencies. For a discussion of our tax contingencies, see Note 5B.

A. Legal Proceedings

Our legal contingencies include, but are not limited to, the following:

•Patent litigation, which typically involves challenges to the coverage and/or validity of patents on various products, processes or dosage forms. We are the plaintiff in the majority of these actions. An adverse outcome in actions in which we are the plaintiff could result in loss of patent protection for a product, a significant loss of revenues from that product or impairment of the value of associated assets.

•Product liability and other product-related litigation, which can include personal injury, consumer, off-label promotion, securities, antitrust and breach of contract claims, among others, often involves highly complex issues relating to medical causation, label warnings and reliance on those warnings, scientific evidence and findings, actual, provable injury and other matters.

•Commercial and other asserted or unasserted matters, which can include acquisition-, licensing-, intellectual property-, collaboration- or co-promotion-related and product-pricing claims and environmental claims and proceedings, can involve complexities that will vary from matter to matter.

•Government investigations, which often are related to the extensive regulation of pharmaceutical companies by national, state and local government agencies in the U.S. and in other jurisdictions.

Certain of these contingencies could result in increased expenses and/or losses, including damages, fines and/or civil penalties, which could be substantial, and/or criminal charges.

We believe that our claims and defenses in matters in which we are a defendant are substantial, but litigation is inherently unpredictable and excessive verdicts do occur. We do not believe that any of these matters will have a material adverse effect on our financial position. However, we could incur judgments, enter into settlements or revise our expectations regarding the outcome of matters, which could have a material adverse effect on our results of operations and/or our cash flows in the period in which the amounts are accrued or paid.

We have accrued for losses that are both probable and reasonably estimable. Substantially all of our contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss can be complex. Consequently, we are unable to estimate the range of reasonably possible loss in excess of amounts accrued. Our assessments, which result from a complex series of judgments about future events and uncertainties, are based on estimates and assumptions that have been deemed reasonable by management, but that may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might cause us to change those estimates and assumptions.

Amounts recorded for legal and environmental contingencies can result from a complex series of judgments about future events and uncertainties and can rely heavily on estimates and assumptions. For proceedings under environmental laws to which a governmental authority is a party, we have adopted a disclosure threshold of $1 million in potential or actual governmental monetary sanctions.

The principal pending matters to which we are a party are discussed below. In determining whether a pending matter is a principal matter, we consider both quantitative and qualitative factors to assess materiality, such as, among others, the amount of damages and the nature of other relief sought, if specified; our view of the merits of the claims and of the strength of our defenses; whether the action purports to be, or is, a class action and, if not certified, our view of the likelihood that a class will be certified by the court; the jurisdiction in which the proceeding is pending; whether related actions have been transferred to multidistrict litigation; any experience that we or, to our knowledge, other companies have had in similar proceedings; whether disclosure of the action would be important to a reader of our financial statements, including whether disclosure might change a reader’s judgment about our financial statements in light of all of the information that is available to the reader; the potential impact of the proceeding on our reputation; and the extent of public interest in the matter. In addition, with respect to patent matters in which we are the plaintiff, we consider, among other things, the financial significance of the product protected by the patent(s) at issue. Some of the matters discussed below include those which management believes that the likelihood of possible loss in excess of amounts accrued is remote.

A1. Legal Proceedings––Patent Litigation

We are involved in suits relating to our patents, including but not limited to, those discussed below. Most involve claims by generic drug manufacturers that patents covering our products (or those of our collaboration/licensing partners to which we have licenses or co-promotion rights and to which we may or may not be a party), processes or dosage forms are invalid and/or do not cover the product of the generic drug manufacturer. Also, counterclaims, as well as various independent actions, have been filed alleging that our assertions of, or attempts to enforce, patent rights with respect to certain products constitute unfair competition and/or violations of antitrust laws. In addition to the challenges to the U.S. patents that are discussed below, patent rights to certain of our products or those of our collaboration/licensing partners are being challenged in various other jurisdictions. For example, some of our collaboration or licensing partners face challenges to the validity of their patent rights in non-U.S. jurisdictions. We are also party to patent damages suits in various jurisdictions pursuant to which generic drug manufacturers, payers, governments or other parties are seeking damages from us for allegedly causing delay of generic entry.

We also are often involved in other proceedings, such as inter partes review, post-grant review, re-examination or opposition proceedings, before the U.S. Patent and Trademark Office, the European Patent Office, or other foreign counterparts relating to our intellectual property or the intellectual property rights of others. Also, if one of our patents is found to be invalid by such proceedings, generic or competitive products could be introduced into the market resulting in the erosion of sales of our existing products. For example, several of the patents in our pneumococcal vaccine portfolio were challenged in inter partes review and post-grant review proceedings in the U.S. In 2017, the Patent Trial and Appeal Board (PTAB) initiated proceedings with respect to two of our pneumococcal vaccine patents. However, the PTAB declined to initiate proceedings as to two other pneumococcal vaccine patents; those two patents, and one other patent, were challenged in federal court in Delaware. In September 2021, Pfizer and a challenger entered into a settlement and license agreement, resolving all worldwide legal proceedings involving that challenger, related to our pneumococcal vaccine patents. Other challenges to pneumococcal vaccine patents remain pending at the PTAB and outside the U.S. The invalidation of any of the patents in our pneumococcal portfolio

could potentially allow additional competitor vaccines into the marketplace. In the event that any of the patents are found valid and infringed, a competitor’s vaccine might be prohibited from entering the market or a competitor might be required to pay us a royalty.

We are also subject to patent litigation pursuant to which one or more third parties seek damages and/or injunctive relief to compensate for alleged infringement of its patents by our commercial or other activities. For example, our Hospira subsidiaries are involved in patent and patent-related disputes over their attempts to bring generic pharmaceutical and biosimilar products to market. If one of our marketed products is found to infringe valid patent rights of a third party, such third party may be awarded significant damages, or we may be prevented from further sales of that product. Such damages may be enhanced as much as three-fold if we or one of our subsidiaries is found to have willfully infringed valid patent rights of a third party.

Actions In Which We Are The Plaintiff

EpiPen

In 2010, King, which we acquired in 2011 and is a wholly-owned subsidiary, brought a patent-infringement action against Sandoz in the U.S. District Court for the District of New Jersey in connection with Sandoz’s abbreviated new drug application (ANDA) filed with the FDA seeking approval to market an epinephrine injectable product. Sandoz is challenging patents, which expire in 2025, covering the next-generation autoinjector for use with epinephrine that is sold under the EpiPen brand name.

Xeljanz (tofacitinib)

Beginning in 2017, we brought patent-infringement actions against several generic manufacturers that filed separate ANDAs with the FDA seeking approval to market their generic versions of tofacitinib tablets in one or both of 5 mg and 10 mg dosage strengths, and in both immediate and extended release forms. To date, we have settled actions with several manufacturers on terms not material to us. The remaining actions continue in the U.S. District Court for the District of Delaware as described below.

In 2018, we brought a separate patent infringement action against Teva Pharmaceuticals USA, Inc. (Teva) asserting the infringement and validity of our patent covering extended release formulations of tofacitinib that was challenged by Teva in its ANDA seeking approval to market a generic version of tofacitinib 11 mg extended release tablets. In September 2021, we settled the case against Teva on terms not material to us.

In January 2021, we brought a separate patent-infringement action against Aurobindo Pharma Limited (Aurobindo) asserting the infringement and validity of the patent covering the active ingredient expiring in December 2025 and the patent covering a polymorphic form of tofacitinib expiring in 2023, which Aurobindo challenged in its ANDA seeking approval to market a generic version of tofacitinib 5 mg and 10 mg tablets.

In October 2021, we brought a separate patent-infringement action against Sinotherapeutics Inc. (Sinotherapeutics) asserting the infringement and validity of our patent covering extended release formulations of tofacitinib that was challenged by Sinotherapeutics in its ANDA seeking approval to market a generic version of tofacitinib 11 mg extended release tablets.

Inlyta (axitinib)

In 2019, Glenmark Pharmaceuticals Limited (Glenmark) notified us that it had filed an ANDA with the FDA seeking approval to market a generic version of Inlyta. Glenmark asserts the invalidity and non-infringement of the crystalline form patent for Inlyta that expires in 2030. In 2019, we filed suit against Glenmark in the U.S. District Court for the District of Delaware, asserting the validity and infringement of the crystalline form patent for Inlyta.

Ibrance (palbociclib)

In 2019, several generic companies notified us that they had filed ANDAs with the FDA seeking approval to market generic versions of Ibrance capsules. The companies asserted the invalidity and non-infringement of two composition of matter patents, one of which expires in 2023 and one of which expires in 2027, as a result of a U.S. Patent Term Extension certificate issued in January 2021, and a method of use patent covering palbociclib, which expires in 2023. In 2019, we brought patent infringement actions against each of the generic filers in various federal courts, asserting the validity and infringement of the patents challenged by the generic companies. In August 2021, the litigation concluded without settlements or a court decision.

Beginning in September 2020, we received correspondence from several generic companies notifying us that they would seek approval to market generic versions of Ibrance capsules. The generic companies assert the invalidity and non-infringement of our crystalline form patent which expires in 2034. Beginning in October 2020, we brought patent infringement actions against each of these generic companies in various federal courts, asserting the validity and infringement of the crystalline form patent. We have settled with certain of these generic companies on terms not material to the company.

Beginning in January 2021, several generic companies notified us that they had filed ANDAs with the FDA seeking approval to market generic versions of Ibrance tablets. The generic companies are challenging some or all of the following patents: (i) the

composition of matter patent expiring in 2027; (ii) the composition of matter patent expiring in 2023; (iii) the method of use patent expiring in 2023; (iv) the crystalline form patent expiring in 2034; and (v) a tablet formulation patent expiring in 2036. We brought patent infringement actions against each of the generic filers in various federal courts, asserting the validity and infringement of the patents challenged by the generic companies.

Eucrisa

Beginning in September 2021, several generic companies notified us that they had filed ANDAs with the FDA seeking approval to market generic versions of Eucrisa. The companies assert the invalidity and non-infringement of a composition of matter patent expiring in 2026, two method of use patents expiring in 2027, and one other method of use patent expiring in 2030. In 2021, we brought patent infringement actions against the generic filers in the U.S. District Court for the District of Delaware, asserting the validity and infringement of the patents challenged by the generic companies.

Matter Involving Our Collaboration/Licensing Partners

Eliquis

In 2017, twenty-five generic companies sent BMS Paragraph-IV certification letters informing BMS that they had filed ANDAs seeking approval of generic versions of Eliquis, challenging the validity and infringement of one or more of the three patents listed in the Orange Book for Eliquis. One of the patents expired in December 2019 and the remaining patents currently are set to expire in 2026 and 2031. Eliquis has been jointly developed and is being commercialized by BMS and Pfizer. BMS and Pfizer filed patent-infringement actions against all generic filers in the U.S. District Court for the District of Delaware and the U.S. District Court for the District of West Virginia, asserting that each of the generic companies’ proposed products would infringe each of the patent(s) that each generic filer challenged. Some generic filers challenged only the 2031 patent, some challenged both the 2031 and 2026 patent, and one generic company challenged all three patents. In August 2020, the U.S. District Court for the District of Delaware ruled that both the 2026 patent and the 2031 patent are valid and infringed by the proposed generic products. In August and September 2020, the generic filers appealed the District Court’s decision to the U.S. Court of Appeals for the Federal Circuit. Prior to the August 2020 ruling, we and BMS settled with certain of the companies on terms not material to us, and we and BMS may settle with other generic companies in the future. In September 2021, the U.S. Court of Appeals for the Federal Circuit affirmed the District Court’s decision.

A2. Legal Proceedings––Product Litigation

We are defendants in numerous cases, including but not limited to those discussed below, related to our pharmaceutical and other products. Plaintiffs in these cases seek damages and other relief on various grounds for alleged personal injury and economic loss.

Asbestos

Between 1967 and 1982, Warner-Lambert owned American Optical Corporation (American Optical), which manufactured and sold respiratory protective devices and asbestos safety clothing. In connection with the sale of American Optical in 1982, Warner-Lambert agreed to indemnify the purchaser for certain liabilities, including certain asbestos-related and other claims. Warner-Lambert was acquired by Pfizer in 2000 and is a wholly owned subsidiary of Pfizer. Warner-Lambert is actively engaged in the defense of, and will continue to explore various means of resolving, these claims.

Numerous lawsuits against American Optical, Pfizer and certain of its previously owned subsidiaries are pending in various federal and state courts seeking damages for alleged personal injury from exposure to products allegedly containing asbestos and other allegedly hazardous materials sold by Pfizer and certain of its previously owned subsidiaries.

There also are a small number of lawsuits pending in various federal and state courts seeking damages for alleged exposure to asbestos in facilities owned or formerly owned by Pfizer or its subsidiaries.

Effexor

Beginning in 2011, actions, including purported class actions, were filed in various federal courts against Wyeth and, in certain of the actions, affiliates of Wyeth and certain other defendants relating to Effexor XR, which is the extended-release formulation of Effexor. The plaintiffs in each of the class actions seek to represent a class consisting of all persons in the U.S. and its territories who directly purchased, indirectly purchased or reimbursed patients for the purchase of Effexor XR or generic Effexor XR from any of the defendants from June 14, 2008 until the time the defendants’ allegedly unlawful conduct ceased. The plaintiffs in all of the actions allege delay in the launch of generic Effexor XR in the U.S. and its territories, in violation of federal antitrust laws and, in certain of the actions, the antitrust, consumer protection and various other laws of certain states, as the result of Wyeth fraudulently obtaining and improperly listing certain patents for Effexor XR in the Orange Book, enforcing certain patents for Effexor XR and entering into a litigation settlement agreement with a generic drug manufacturer with respect to Effexor XR. Each of the plaintiffs seeks treble damages (for itself in the individual actions or on behalf of the putative class

in the purported class actions) for alleged price overcharges for Effexor XR or generic Effexor XR in the U.S. and its territories since June 14, 2008. All of these actions have been consolidated in the U.S. District Court for the District of New Jersey.

In 2014, the District Court dismissed the direct purchaser plaintiffs’ claims based on the litigation settlement agreement, but declined to dismiss the other direct purchaser plaintiff claims. In 2015, the District Court entered partial final judgments as to all settlement agreement claims, including those asserted by direct purchasers and end-payer plaintiffs, which plaintiffs appealed to the U.S. Court of Appeals for the Third Circuit. In 2017, the U.S. Court of Appeals for the Third Circuit reversed the District Court’s decisions and remanded the claims to the District Court.

Lipitor

Beginning in 2011, purported class actions relating to Lipitor were filed in various federal courts against, among others, Pfizer, certain Pfizer affiliates, and, in most of the actions, Ranbaxy and certain Ranbaxy affiliates. The plaintiffs in these various actions seek to represent nationwide, multi-state or statewide classes consisting of persons or entities who directly purchased, indirectly purchased or reimbursed patients for the purchase of Lipitor (or, in certain of the actions, generic Lipitor) from any of the defendants from March 2010 until the cessation of the defendants’ allegedly unlawful conduct (the Class Period). The plaintiffs allege delay in the launch of generic Lipitor, in violation of federal antitrust laws and/or state antitrust, consumer protection and various other laws, resulting from (i) the 2008 agreement pursuant to which Pfizer and Ranbaxy settled certain patent litigation involving Lipitor and Pfizer granted Ranbaxy a license to sell a generic version of Lipitor in various markets beginning on varying dates, and (ii) in certain of the actions, the procurement and/or enforcement of certain patents for Lipitor. Each of the actions seeks, among other things, treble damages on behalf of the putative class for alleged price overcharges for Lipitor (or, in certain of the actions, generic Lipitor) during the Class Period. In addition, individual actions have been filed against Pfizer, Ranbaxy and certain of their affiliates, among others, that assert claims and seek relief for the plaintiffs that are substantially similar to the claims asserted and the relief sought in the purported class actions described above. These various actions have been consolidated for pre-trial proceedings in a Multi-District Litigation in the U.S. District Court for the District of New Jersey.

In September 2013 and 2014, the District Court dismissed with prejudice the claims of the direct purchasers. In October and November 2014, the District Court dismissed with prejudice the claims of all other Multi-District Litigation plaintiffs. All plaintiffs have appealed the District Court’s orders dismissing their claims with prejudice to the U.S. Court of Appeals for the Third Circuit. In addition, the direct purchaser class plaintiffs appealed the order denying their motion to amend the judgment and for leave to amend their complaint to the Court of Appeals. In 2017, the Court of Appeals reversed the District Court’s decisions and remanded the claims to the District Court.

Also, in 2013, the State of West Virginia filed an action in West Virginia state court against Pfizer and Ranbaxy, among others, that asserts claims and seeks relief on behalf of the State of West Virginia and residents of that state that are substantially similar to the claims asserted and the relief sought in the purported class actions described above.

EpiPen (Direct Purchaser)

In February 2020, a lawsuit was filed in the U.S. District Court for the District of Kansas against Pfizer, its affiliates King and Meridian, and various Mylan entities, on behalf of a purported U.S. nationwide class of direct purchaser plaintiffs who purchased EpiPen devices directly from the defendants. Plaintiffs in this action generally allege that Pfizer and Mylan conspired to delay market entry of generic EpiPen through the settlement of patent litigation regarding EpiPen, and thereby delayed market entry of generic EpiPen in violation of federal antitrust law. Plaintiffs seek treble damages for alleged overcharges for EpiPen since 2011. In July 2021, the District Court granted defendants’ motion to dismiss the direct purchaser complaint, without prejudice. In September 2021, plaintiffs filed an amended complaint.

Nexium 24HR and Protonix

A number of individual and multi-plaintiff lawsuits have been filed against Pfizer, certain of its subsidiaries and/or other pharmaceutical manufacturers in various federal and state courts alleging that the plaintiffs developed kidney-related injuries purportedly as a result of the ingestion of certain proton pump inhibitors. The cases against Pfizer involve Protonix and/or Nexium 24HR and seek compensatory and punitive damages and, in some cases, treble damages, restitution or disgorgement. In 2017, the federal actions were ordered transferred for coordinated pre-trial proceedings to a Multi-District Litigation in the U.S. District Court for the District of New Jersey. As part of our Consumer Healthcare JV transaction with GSK, the JV has agreed to assume, and to indemnify Pfizer for, liabilities arising out of such litigation to the extent related to Nexium 24HR.

Docetaxel

•Personal Injury Actions

A number of lawsuits have been filed against Hospira and Pfizer in various federal and state courts alleging that plaintiffs who were treated with Docetaxel developed permanent hair loss. The significant majority of the cases also name other defendants, including the manufacturer of the branded product, Taxotere. Plaintiffs seek compensatory and punitive damages.

In 2016, the federal cases were transferred for coordinated pre-trial proceedings to a Multi-District Litigation in the U.S. District Court for the Eastern District of Louisiana.

•Mississippi Attorney General Government Action

In 2018, the Attorney General of Mississippi filed a complaint in Mississippi state court against the manufacturer of the branded product and eight other manufacturers including Pfizer and Hospira, alleging, with respect to Pfizer and Hospira, a failure to warn about a risk of permanent hair loss in violation of the Mississippi Consumer Protection Act. The action seeks civil penalties and injunctive relief.

Array Securities Litigation

In 2017, two purported class actions were filed in the U.S. District Court for the District of Colorado alleging that Array, which we acquired in 2019 and is our wholly owned subsidiary, and certain of its former officers violated federal securities laws in connection with certain disclosures made, or omitted, by Array regarding the NRAS-mutant melanoma program. In 2018, the actions were consolidated into a single proceeding. In March 2021, the parties reached an agreement in principle to resolve the litigation on terms not material to Pfizer.

Zantac

A number of lawsuits have been filed against Pfizer in various federal and state courts alleging that plaintiffs developed various types of cancer, or face an increased risk of developing cancer, purportedly as a result of the ingestion of Zantac. The significant majority of these cases also name other defendants that have historically manufactured and/or sold Zantac. Pfizer has not sold Zantac since 2006, and only sold an OTC version of the product. Plaintiffs seek compensatory and punitive damages.

In February 2020, the federal actions were transferred for coordinated pre-trial proceedings to a Multi-District Litigation in the U.S. District Court for the Southern District of Florida. Plaintiffs in the Multi-District Litigation have filed against Pfizer and many other defendants a master personal injury complaint, a consolidated consumer class action complaint alleging, among other things, claims under consumer protection statutes of all 50 states, and a medical monitoring complaint seeking to certify medical monitoring classes under the laws of 13 states. Plaintiffs previously had filed a consolidated third-party payor class action complaint alleging violation of the RICO statute and seeking reimbursement for payments made for the prescription version of Zantac, but the Multi-District Litigation court dismissed that complaint; Plaintiffs have appealed the dismissal to the U.S. Court of Appeals for the Eleventh Circuit. In addition, (i) Pfizer has received service of two Canadian class action complaints naming Pfizer and other defendants, and seeking compensatory and punitive damages for personal injury and economic loss, allegedly arising from the defendants’ sale of Zantac in Canada; and (ii) the State of New Mexico and the Mayor and City Council of Baltimore separately filed civil actions against Pfizer and many other defendants in state court, alleging various state statutory and common law claims in connection with the defendants’ alleged sale of Zantac in those jurisdictions. In April 2021, a Judicial Council Coordinated Proceeding was created in the Superior Court of California in Alameda County to coordinate personal injury actions against Pfizer and other defendants filed in California state court.

Chantix

Beginning in August 2021, a number of putative class actions have been filed against Pfizer in various U.S. federal courts following Pfizer’s voluntary recall of Chantix due to the presence of a nitrosamine, N-nitroso-varenicline. Plaintiffs assert that they suffered economic harm purportedly as a result of purchasing Chantix or generic varenicline medicines sold by Pfizer. Plaintiffs seek to represent nationwide and state-specific classes and seek various remedies, including damages and medical monitoring. Similar putative class actions have been filed in Canada and Israel, where the product brand is Champix.

A3. Legal Proceedings––Commercial and Other Matters

Monsanto-Related Matters

In 1997, Monsanto Company (Former Monsanto) contributed certain chemical manufacturing operations and facilities to a newly formed corporation, Solutia Inc. (Solutia), and spun off the shares of Solutia. In 2000, Former Monsanto merged with Pharmacia & Upjohn Company to form Pharmacia. Pharmacia then transferred its agricultural operations to a newly created subsidiary, named Monsanto Company (New Monsanto), which it spun off in a two-stage process that was completed in 2002. Pharmacia was acquired by Pfizer in 2003 and is a wholly owned subsidiary of Pfizer.

In connection with its spin-off that was completed in 2002, New Monsanto assumed, and agreed to indemnify Pharmacia for, any liabilities related to Pharmacia’s former agricultural business. New Monsanto has defended and/or is defending Pharmacia in connection with various claims and litigation arising out of, or related to, the agricultural business, and has been indemnifying Pharmacia when liability has been imposed or settlement has been reached regarding such claims and litigation.

In connection with its spin-off in 1997, Solutia assumed, and agreed to indemnify Pharmacia for, liabilities related to Former Monsanto’s chemical businesses. As the result of its reorganization under Chapter 11 of the U.S. Bankruptcy Code, Solutia’s

indemnification obligations relating to Former Monsanto’s chemical businesses are primarily limited to sites that Solutia has owned or operated. In addition, in connection with its spin-off that was completed in 2002, New Monsanto assumed, and agreed to indemnify Pharmacia for, any liabilities primarily related to Former Monsanto’s chemical businesses, including, but not limited to, any such liabilities that Solutia assumed. Solutia’s and New Monsanto’s assumption of, and agreement to indemnify Pharmacia for, these liabilities apply to pending actions and any future actions related to Former Monsanto’s chemical businesses in which Pharmacia is named as a defendant, including, without limitation, actions asserting environmental claims, including alleged exposure to polychlorinated biphenyls. Solutia and/or New Monsanto are defending Pharmacia in connection with various claims and litigation arising out of, or related to, Former Monsanto’s chemical businesses, and have been indemnifying Pharmacia when liability has been imposed or settlement has been reached regarding such claims and litigation.

Environmental Matters

In 2009, we submitted a revised site-wide feasibility study with regard to the Wyeth Holdings Corporation (formerly, American Cyanamid Company) discontinued industrial chemical facility in Bound Brook, New Jersey. In 2011, Wyeth Holdings Corporation executed an Administrative Settlement Agreement and Order on Consent for Removal Action (the 2011 Administrative Settlement Agreement) with the U.S. Environmental Protection Agency (EPA) with regard to the Bound Brook facility. In accordance with the 2011 Administrative Settlement Agreement, we completed construction of an interim remedy. In 2012, the EPA issued a final remediation plan for the Bound Brook facility’s main plant area. In 2013, Wyeth Holdings Corporation (now Wyeth Holdings LLC) entered into an Administrative Settlement Agreement and Order on Consent with the EPA to allow us to undertake detailed engineering design of the remedy for the main plant area and to perform a focused feasibility study for two adjacent lagoons. In 2015, the U.S., on behalf of the EPA, filed a complaint and consent decree with the federal District Court for the District of New Jersey that allows Wyeth Holdings LLC to complete the design and to implement the remedy for the main plant area. The consent decree (which supersedes the 2011 Administrative Settlement Agreement) was entered by the District Court in 2015. In 2018, the EPA issued a final remediation plan for the two adjacent lagoons. In 2019, Wyeth Holdings LLC entered into an Administrative Settlement Agreement and Order on Consent with the EPA to allow us to undertake detailed engineering design of the remedy for the lagoons. In September 2021, the U.S., on behalf of the EPA, filed a complaint and consent decree with the federal District Court for the District of New Jersey that will allow Wyeth Holdings LLC to complete the design and implement the remedy for the two adjacent lagoons.

We have accrued for the estimated costs of the site remedies for the Bound Brook facility.

We are a party to a number of other proceedings brought under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended, and other state, local or foreign laws in which the primary relief sought is the cost of past and/or future remediation.

In 2017, a number of U.S. service members, civilians, and their families brought a complaint in the U.S. District Court for the District of Columbia against a number of pharmaceutical and medical devices companies, including Pfizer and certain of its subsidiaries, alleging that the defendants violated the U.S. Anti-Terrorism Act. The complaint alleges that the defendants provided funding for terrorist organizations through their sales practices pursuant to pharmaceutical and medical device contracts with the Iraqi Ministry of Health, and seeks monetary relief. In July 2020, the District Court granted defendants’ motions to dismiss and dismissed all of plaintiffs’ claims. The plaintiffs are appealing the District Court’s decision.

Allergan Complaint for Indemnity

In 2019, Pfizer was named as a defendant in a complaint, along with King, filed by Allergan Finance LLC (Allergan) in the Supreme Court of the State of New York, asserting claims for indemnity related to Kadian, which was owned for a short period by King in 2008, prior to Pfizer's acquisition of King in 2010. This suit was voluntarily discontinued without prejudice in January 2021.

Breach of Contract––Xalkori/Lorbrena

We are a defendant in a breach of contract action brought by New York University (NYU) in the Supreme Court of the State of New York (Supreme Court). NYU alleges that it is entitled to royalties on Pfizer’s sales of Xalkori under the terms of a Research and License Agreement between NYU and Sugen, Inc. Sugen, Inc. was acquired by Pharmacia in August 1999, and Pharmacia was acquired by Pfizer in 2003 and is a wholly owned subsidiary of Pfizer. The action was originally filed in 2013. In 2015, the Supreme Court dismissed the action and, in 2017, the New York State Appellate Division reversed the decision and remanded the proceedings to the Supreme Court. In January 2020, the Supreme Court denied both parties’ summary judgment motions.

In October 2020, NYU filed a separate breach of contract action against Pfizer alleging that it is entitled to royalties on sales of Lorbrena under the terms of the same NYU-Sugen, Inc. Research and Licensing Agreement.

A4. Legal Proceedings––Government Investigations

We are subject to extensive regulation by government agencies in the U.S., other developed markets and multiple emerging markets in which we operate. Criminal charges, substantial fines and/or civil penalties, limitations on our ability to conduct business in applicable jurisdictions, corporate integrity or deferred prosecution agreements, as well as reputational harm and increased public interest in the matter could result from government investigations in the U.S. and other jurisdictions in which we do business. In addition, in a qui tam lawsuit in which the government declines to intervene, the relator may still pursue a suit for the recovery of civil damages and penalties on behalf of the government. Among the investigations by government agencies are the matters discussed below.

Greenstone Investigations

•U.S. Department of Justice Antitrust Division Investigation

Since July 2017, the U.S. Department of Justice's Antitrust Division has been investigating our former Greenstone generics business. We believe this is related to an ongoing broader antitrust investigation of the generic pharmaceutical industry. We have produced records relating to this investigation.

•State Attorneys General Generics Antitrust Litigation

In April 2018, Greenstone received requests for information from the Antitrust Department of the Connecticut Office of the Attorney General. In May 2019, Attorneys General of more than 40 states plus the District of Columbia and Puerto Rico filed a complaint against a number of pharmaceutical companies, including Greenstone and Pfizer. The matter has been consolidated with a Multi-District Litigation in the Eastern District of Pennsylvania. As to Greenstone and Pfizer, the complaint alleges anticompetitive conduct in violation of federal and state antitrust laws and state consumer protection laws. In June 2020, the State Attorneys General filed a new complaint against a large number of companies, including Greenstone and Pfizer, making similar allegations, but concerning a new set of drugs. This complaint was transferred to the Multi-District Litigation in July 2020.

Subpoena relating to Manufacturing of Quillivant XR

In October 2018, we received a subpoena from the U.S. Attorney’s Office for the Southern District of New York (SDNY) seeking records relating to our relationship with another drug manufacturer and its production and manufacturing of drugs including, but not limited to, Quillivant XR. We have produced records pursuant to the subpoena.

Government Inquiries relating to Meridian Medical Technologies

In February 2019, we received a civil investigative demand from the U.S. Attorney’s Office for the SDNY. The civil investigative demand seeks records and information related to alleged quality issues involving the manufacture of auto-injectors at our Meridian site. In August 2019, we received a HIPAA subpoena from the U.S. Attorney’s Office for the Eastern District of Missouri seeking similar records and information. We are producing records in response to these requests.

U.S. Department of Justice/SEC Inquiry relating to Russian Operations

In June 2019, we received an informal request from the U.S. Department of Justice’s Foreign Corrupt Practices Act (FCPA) Unit seeking documents relating to our operations in Russia. In September 2019, we received a similar request from the SEC’s FCPA Unit. We have produced records pursuant to these requests.

Docetaxel––Mississippi Attorney General Government Investigation

See Legal Proceedings––Product Litigation––Docetaxel––Mississippi Attorney General Government Investigation above for information regarding a government investigation related to Docetaxel marketing practices.

U.S. Department of Justice Inquiries relating to India Operations

In March 2020, we received an informal request from the U.S. Department of Justice's Consumer Protection Branch seeking documents relating to our manufacturing operations in India, including at our former facility located at Irrungattukottai in India. In April 2020, we received a similar request from the U.S. Attorney’s Office for the SDNY regarding a civil investigation concerning operations at our facilities in India. We are producing records pursuant to these requests.

U.S. Department of Justice/SEC Inquiry relating to China Operations

In June 2020, we received an informal request from the U.S. Department of Justice's FCPA Unit seeking documents relating to our operations in China. In August 2020, we received a similar request from the SEC’s FCPA Unit. We are producing records pursuant to these requests.

Zantac––State of New Mexico and Mayor and City Council of Baltimore Civil Actions

See Note 12A2. Contingencies and Certain Commitments: Legal Proceedings––Product Litigation––Zantac above for information regarding civil actions separately filed by the State of New Mexico and the Mayor and City Council of Baltimore alleging various state statutory and common law claims in connection with the defendants’ alleged sale of Zantac in those jurisdictions.

A5. Legal Proceedings––Matters Resolved During the First Nine Months of 2021

During the first nine months of 2021, certain matters, including the matter discussed below, were resolved or became the subject of definitive settlement agreements or settlement agreements-in-principle.

EpiPen

Beginning in 2017, purported class actions were filed in various federal courts by indirect purchasers of EpiPen against Pfizer, and/or its affiliates King and Meridian, and/or various entities affiliated with Mylan, and Mylan former Chief Executive Officer, Heather Bresch. The plaintiffs in these actions represent U.S. nationwide classes comprising persons or entities who paid for any portion of the end-user purchase price of an EpiPen between 2009 until the cessation of the defendants’ allegedly unlawful conduct. Against Pfizer and/or its affiliates, plaintiffs in these actions generally allege that Pfizer’s and/or its affiliates’ settlement of patent litigation regarding EpiPen delayed market entry of generic EpiPen in violation of federal and various state antitrust laws. At least one lawsuit also alleges that Pfizer and/or Mylan violated the federal Racketeer Influenced and Corrupt Organizations Act (RICO). Plaintiffs also filed various federal antitrust, state consumer protection and unjust enrichment claims against, and relating to conduct attributable solely to, Mylan and/or its affiliates regarding EpiPen. Plaintiffs seek treble damages for alleged overcharges for EpiPen since 2011. In 2017, all of these indirect purchase actions were consolidated for coordinated pre-trial proceedings in a Multi-District Litigation in the U.S. District Court for the District of Kansas with other EpiPen-related actions against Mylan and/or its affiliates to which Pfizer, King and Meridian are not parties. In July 2021, Pfizer and plaintiffs filed a stipulation of settlement to resolve the Multi-District Litigation for $345 million. The settlement is subject to court approval, and the payment has been made in accordance with the terms of the settlement agreement.

B. Guarantees and Indemnifications

In the ordinary course of business and in connection with the sale of assets and businesses and other transactions, we often indemnify our counterparties against certain liabilities that may arise in connection with the transaction or that are related to events and activities prior to or following a transaction. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we may be required to reimburse the loss. These indemnifications are generally subject to various restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of October 3, 2021, the estimated fair value of these indemnification obligations was not significant.

In addition, in connection with our entry into certain agreements and other transactions, our counterparties may agree to indemnify us. For example, in November 2020, we and Mylan completed the transaction to spin-off our Upjohn Business and combine it with Mylan to form Viatris. As part of the transaction and as previously disclosed, Viatris has agreed to assume, and to indemnify Pfizer for, liabilities arising out of certain matters.

We have also guaranteed the long-term debt of certain companies that we acquired, which are now subsidiaries of Pfizer. See Note 7D.

C. Contingent Consideration for Acquisitions

We may be required to make payments to sellers for certain prior business combinations that are contingent upon future events or outcomes. For additional information, see Note 1D in our 2020 Form 10-K.

(f)Total Sterile Injectable Pharmaceuticals represents the total of all branded and generic injectable products in the Hospital therapeutic area, including anti-infective sterile injectable pharmaceuticals.

Deferred Revenues

Our deferred revenues primarily relate to advance payments received or receivable in connection with contracts that we entered into during 2021 and 2020 with various government or government sponsored customers in international markets for supply of Comirnaty. The deferred revenues associated with the advance payments related to Comirnaty total $3.7 billion as of October 3, 2021 and $957 million as of December 31, 2020, with $3.4 billion and $264 million recorded in current liabilities and noncurrent liabilities, respectively as of October 3, 2021, and $957 million recorded in current liabilities as of December 31, 2020. The increase in the Comirnaty deferred revenues during the first nine months of 2021 was the result of additional advance

payments received as we entered into new or amended contracts or as we invoiced customers in advance of vaccine deliveries less amounts recognized in Revenues as we delivered doses to our customers. During the third quarter and first nine months of 2021, we recognized revenue of $136 million and $950 million, respectively, that was included in the balance of Comirnaty deferred revenues as of December 31, 2020. The Comirnaty deferred revenues as of October 3, 2021 will be recognized in Revenues proportionately as we deliver doses of the vaccine to our customers and satisfy our performance obligation under the contracts, with the amounts included in current liabilities expected to be recognized in Revenues within the next 12 months, and the amounts included in noncurrent liabilities expected to be recognized in Revenues in the fourth quarter of 2022 and in 2023.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

We prepared these condensed consolidated financial statements in conformity with U.S. GAAP, consistent in all material respects with those applied in our 2020 Form 10-K, except as disclosed in Note 1C. As permitted under the SEC requirements for interim reporting, certain footnotes or other financial information have been condensed or omitted.

These financial statements include all normal and recurring adjustments that are considered necessary for the fair statement of results for the interim periods presented. The information included in this Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our 2020 Form 10-K. Revenues, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be representative of those for the full year.

Pfizer’s fiscal quarter-end for subsidiaries operating outside the U.S. is as of and for the three and nine months ended August 29, 2021 and August 23, 2020, and for U.S. subsidiaries is as of and for the three and nine months ended October 3, 2021 and September 27, 2020.

Business development activities impacted financial results in the periods presented. See Note 1A in our 2020 Form 10-K, and Note 2. On November 16, 2020, we completed the spin-off and the combination of our Upjohn Business with Mylan to form Viatris. For additional information, see Note 2B in our 2020 Form 10-K. On December 21, 2020, which fell in Pfizer’s international first quarter of 2021, Pfizer and Viatris completed the termination of the Mylan-Japan collaboration pursuant to an agreement dated November 13, 2020, and we transferred related inventories and operations that were part of the Mylan-Japan collaboration to Viatris. As a result, the financial position and results of operations of the Upjohn Business and the Mylan-Japan collaboration are presented as discontinued operations. Prior-period information has been restated to reflect our current organization structure.

New Accounting Standard Adopted

New Accounting Standard Adopted in 2021On January 1, 2021, we adopted a new accounting standard for income tax that eliminates certain exceptions to the guidance related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The adoption of this guidance did not have a material impact on our condensed consolidated financial statements.

Change in Accounting Principle

Change in Accounting PrincipleIn the first quarter of 2021, we adopted a change in accounting principle to a more preferable policy under U.S. GAAP to immediately recognize actuarial gains and losses arising from the remeasurement of our pension and postretirement plans (MTM Accounting). Under the prior policy, we deferred recognition of these gains and losses in Accumulated other comprehensive loss. The accumulated actuarial gains/losses outside of a “corridor” were then amortized into net periodic benefit costs over the average remaining service period or the average life expectancy of participants. This change has been applied to all pension and postretirement plans on a retrospective basis for all prior periods presented, and as of January 1, 2020, resulted in a cumulative effect decrease to Retained earnings of $6.3 billion, with a corresponding offset to Accumulated other comprehensive loss. Each time a pension or postretirement plan is remeasured, the actuarial gain or loss is recognized immediately and classified as Other (income)/deductions––net.We believe that MTM Accounting is a more preferable policy as it provides improved transparency of results and performance, better alignment with fair value accounting principles and a better reflection of current economic and interest rate trends on plan investments and assumptions and the actuarial impact of plan remeasurements.

Revenues and Trade Accounts Receivable

Revenues and Trade Accounts Receivable

Customers––Our prescription pharmaceutical products are sold principally to wholesalers, but we also sell directly to retailers, hospitals, clinics, government agencies and pharmacies. In the U.S., we primarily sell our vaccine products directly to the federal government, CDC, wholesalers, individual provider offices, retail pharmacies and integrated delivery networks. Outside the U.S., we primarily sell our vaccines to government and non-government institutions.

Deductions from Revenues––Our accruals for Medicare, Medicaid and related state program and performance-based contract rebates, chargebacks, sales allowances and sales returns and cash discounts are as follows:

(MILLIONS)	October 3, 2021		December 31, 2020
Reserve against Trade accounts receivable, less allowance for doubtful accounts	$	996	$	861
Other current liabilities:
Accrued rebates	3,470		3,017
Other accruals	470		436
Other noncurrent liabilities	503		399
Total accrued rebates and other sales-related accruals	$	5,439	$	4,712

Trade Accounts Receivable––Trade accounts receivable are stated at their net realizable value. The allowance for credit losses reflects our best estimate of expected credit losses of the receivables portfolio determined on the basis of historical experience, current information, and forecasts of future economic conditions. In developing the estimate for expected credit losses, trade accounts receivables are segmented into pools of assets depending on market (U.S. versus international), delinquency status, and customer type (high risk versus low risk and government versus non-government), and fixed reserve percentages are established for each pool of trade accounts receivables.

In determining the reserve percentages for each pool of trade accounts receivables, we considered our historical experience with certain customers and customer types, regulatory and legal environments, country and political risk, and other relevant current and future forecasted macroeconomic factors. These credit risk indicators are monitored on a quarterly basis to determine whether there have been any changes in the economic environment that would indicate the established reserve percentages should be adjusted, and are considered on a regional basis to reflect more geographic-specific metrics. Additionally, write-offs and recoveries of customer receivables are tracked against collections on a quarterly basis to determine whether the reserve percentages remain appropriate. When management becomes aware of certain customer-specific factors that impact credit risk,

specific allowances for these known troubled accounts are recorded. Trade accounts receivable are written off after all reasonable means to collect the full amount (including litigation, where appropriate) have been exhausted.

(a)OID = Other (income)/deductions—net, included in Other (income)/deductions—net in the condensed consolidated statements of income. COS = Cost of Sales, included in Cost of sales in the condensed consolidated statements of income. OCI = Other comprehensive income/(loss), included in the condensed consolidated statements of comprehensive income.

(b)The amounts reclassified from OCI into COS were:

•a net loss of $18 million in the third quarter of 2021;

•a net loss of $94 million in the first nine months of 2021;

•a net gain of $34 million in the third quarter of 2020; and

•a net gain of $184 million in the first nine months of 2020.

The remaining amounts were reclassified from OCI into OID. Based on quarter-end foreign exchange rates that are subject to change, we expect to reclassify a pre-tax gain of $202 million within the next 12 months into income. The maximum length of time over which we are hedging our exposure to the variability in future foreign exchange cash flows is approximately 22 years and relates to foreign currency debt.

(c)The amounts reclassified from OCI were reclassified into OID.

(d)Short-term borrowings and long-term debt include foreign currency borrowings which are used in net investment hedges. The short-term borrowings carrying value as of October 3, 2021 was $1.2 billion. The long-term debt carrying values as of October 3, 2021 and December 31, 2020 were $862 million and $2.1 billion, respectively.

OCI = Other comprehensive income/(loss), included in the condensed consolidated statements of comprehensive income

[2] The amounts reclassified from OCI were reclassified into OID.

[3] Reclassified into Other (income)/deductions—net and Cost of sales. See Note 7E.

[4] The amounts reclassified from OCI into COS were: •a net loss of $18 million in the third quarter of 2021; •a net loss of $94 million in the first nine months of 2021; •a net gain of $34 million in the third quarter of 2020; and •a net gain of $184 million in the first nine months of 2020. The remaining amounts were reclassified from OCI into OID. Based on quarter-end foreign exchange rates that are subject to change, we expect to reclassify a pre-tax gain of $202 million within the next 12 months into income. The maximum length of time over which we are hedging our exposure to the variability in future foreign exchange cash flows is approximately 22 years and relates to foreign currency debt.

[5] Short-term borrowings and long-term debt include foreign currency borrowings which are used in net investment hedges. The short-term borrowings carrying value as of October 3, 2021 was $1.2 billion. The long-term debt carrying values as of October 3, 2021 and December 31, 2020 were $862 million and $2.1 billion, respectively.
