NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

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 2025 Form 10-K. 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 2025 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 months ended February 22, 2026 and February 23, 2025, and for U.S. subsidiaries is as of and for the three months ended March 29, 2026 and March 30, 2025.

We manage our commercial operations through two operating segments, each led by a single manager: Biopharma and PC1. Biopharma is the only reportable segment. See Note 13A**.

B. Revenues and Trade Accounts Receivable


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)	March 29, 2026		December 31, 2025
Reserve against Trade accounts receivable, net of allowance for doubtful accounts	$	1,699	$	1,803
Other current liabilities:
Accrued rebates	8,846		7,909
Other accruals	718		750
Other noncurrent liabilities	287		1,204
Total accrued rebates and other sales-related accruals	$	11,550	$	11,666

*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, delinquency status, and customer type (high risk versus low risk and government versus non-government), and 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. When management becomes aware of certain customer-specific factors that impact credit risk, specific allowances for these known troubled accounts are recorded.

During the three months ended March 29, 2026 and March 30, 2025, 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 2025 Form 10-K.

Note 2. Acquisition, In-Licensing Arrangement and Sale of Investment

A. Acquisition

*Metsera––*On November 13, 2025, we acquired Metsera, a clinical-stage biopharmaceutical company accelerating the next generation of medicines for obesity and cardiometabolic diseases, for $65.60 per share in cash plus a contingent value right (CVR) of up to $20.65 per share in potential additional payments (up to $2.3 billion) tied to the achievement of three specified milestones: $4.60 per share following the Phase 3 clinical trial start of Metsera’s injectable GLP-1 receptor antagonist MET-097i+amylin analog MET-233i combination, $6.40 per share following FDA approval of Metsera’s monthly MET-097i monotherapy and $9.65 per share following FDA approval of Metsera’s monthly MET-097i+MET-233i combination. The total fair value of the consideration transferred was $8.0 billion ($7.8 billion net of cash acquired), which includes the fair value of $632 million for the noncash CVRs and $475 million for employee stock awards related to pre-acquisition service.

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

In connection with this business combination, we provisionally recorded: (i) $8.0 billion of identifiable intangible assets, net, consisting of IPR&D, (ii) $2.0 billion of Goodwill, (iii) $1.6 billion of net deferred tax liabilities, and (iv) $672 million of contingent consideration liability assumed from Metsera. Goodwill, which resulted primarily from the recognition of deferred tax liabilities, is related to our Biopharma segment and is not deductible for tax purposes. The contingent consideration liability was recorded at fair value and relates to Metsera’s 2023 acquisition of Zihipp Ltd (Zihipp). As a part of that transaction, the former Zihipp shareholders are entitled to future potential development, regulatory and commercialization milestone payments, along with low-single digit royalties on net product sales on the MET-097i and MET-233i product candidates. The allocation of the consideration transferred to the assets acquired and liabilities assumed has not yet been finalized.

B. In-Licensing Arrangement

In-Licensing Arrangement with Sciwind Biosciences––In February 2026, Pfizer and Sciwind Biosciences announced a strategic commercialization collaboration in which Pfizer obtained exclusive commercialization rights for Sciwind Biosciences’ glucagon-like peptide 1 (GLP-1) receptor agonist ecnoglutide in Mainland China. Sciwind Biosciences remains the Marketing Authorization Holder and is responsible for R&D, registration, manufacturing and supply of the product. Sciwind Biosciences is eligible to receive an aggregate of up to $495 million in upfront, regulatory and sales milestone payments.

C. Sale of Investment

ViiV––On March 31, 2026, which fell in our second fiscal quarter of 2026, Pfizer completed the exit of its 11.7% investment in ViiV (carrying value of zero) and received $1.875 billion in cash proceeds. See Note 2C in our 2025 Form 10-K.

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

A. Realigning Our Cost Base Program

In the fourth quarter of 2023, we announced that we launched a multi-year, enterprise-wide cost realignment program that aims to realign our costs with our longer-term revenue expectations. In the second quarter of 2025, we identified additional productivity opportunities to further reduce costs primarily in SI&A, driven in large part by enhanced digital enablement, including automation and AI, and simplification of business processes.

We expect costs associated with these components of the program to be incurred through 2027 and to total approximately $4.7 billion, representing primarily cash expenditures for severance, implementation, exit, and digital enablement costs, as well as non-cash asset write downs of which $3.1 billion is associated with our Biopharma segment.

Additionally, in connection with our efforts to simplify the structure and sharpen the focus of our R&D organization, in the first quarter of 2025, we expanded this program after having identified additional opportunities to drive improvements in productivity and operational efficiencies through enhanced digital enablement, including automation and AI, and simplification of business processes. We expect costs to implement these initiatives to be incurred through 2026 and to total approximately $600 million, primarily representing cash expenditures for severance, digital enablement and implementation, all of which is associated with our Biopharma segment. The majority of these costs were recorded in 2025, with cash outlays expected primarily through 2026.

We expect costs associated with all the components of this program to total approximately $5.3 billion of which $3.7 billion is associated with the Biopharma segment.

From the start of this program through March 29, 2026, we incurred total costs of $4.3 billion, of which $3.3 billion is associated with our Biopharma segment (including $2.9 billion of restructuring charges).

B. Manufacturing Optimization Program

In the second quarter of 2024, we announced that we launched a multi-year, multi-phased program to reduce our costs of goods sold, which includes operational efficiencies, network structure changes, and product portfolio enhancements. The first phase of this program is primarily focused on operational efficiencies, and we expect costs for this first phase to total approximately $1.4 billion, primarily representing cash expenditures for severance and implementation costs, all of which is associated with our Biopharma segment. From the start of this program through March 29, 2026, we incurred costs of $1.1 billion (including $853 million of restructuring charges). These costs were recorded primarily through 2025, with cash outlays expected primarily through 2026.

(c)See Notes 1D and 16D in our 2025 Form 10-K and N ote 7A.

Note 5. Tax Matters

A. Taxes on Income from Continuing Operations

Our effective tax rate for continuing operations was 14.6% for the first quarter of 2026, compared to (6.8)% for the first quarter of 2025. The increase in the effective tax rate for the first quarter of 2026, compared to the first quarter of 2025, was primarily due to an unfavorable change in the jurisdictional mix of earnings, and non-recurrence of favorable global income tax resolutions.

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 (Transition Tax liability) over eight years through 2026. The eighth and final annual installment was paid by its April 15, 2026 due date and was reported in current Income taxes payable as of March 29, 2026. Our obligations may vary due to the availability of attributes such as foreign tax and other credit carryforwards or carrybacks.

See Note 5A in our 2025 Form 10-K for information on our income taxes paid (net of refunds received).

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. Tax years 2019-2022 are under audit. Tax years 2023-2026 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 and certain related audits, appeals and investigations in certain major international tax jurisdictions dating back to 2016.

See Note 5D in our 2025 Form 10-K.

*Financial Assets and Liabilities Not Measured at Fair Value on a Recurring Basis––*The carrying value of Long-term debt, excluding the current portion, was $61 billion as of March 29, 2026 and $62 billion as of December 31, 2025. The estimated fair value of such debt, using a market approach and Level 2 inputs, was $58 billion as of March 29, 2026 and $60 billion as of December 31, 2025.

The differences between the estimated fair values and carrying values of held-to-maturity debt securities, private equity securities, long-term receivables and short-term borrowings not measured at fair value on a recurring basis were not significant as of March 29, 2026 and December 31, 2025. The fair value measurements of our held-to-maturity debt securities and short-term borrowings are based on Level 2 inputs. The fair value measurements of our long-term receivables and private equity securities are based on Level 3 inputs.

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. Where foreign exchange risk is not offset by other exposures, 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, Chinese renminbi, Japanese yen, Canadian dollar, and Swedish krona, and include a portion of our forecasted foreign exchange-denominated intercompany inventory sales hedged up to two years. We may also seek to protect against possible declines in the net investments of our foreign business entities.

*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

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 17C in our 2025 Form 10-K.

As of March 29, 2026, the largest investment exposures in our portfolio consisted primarily of U.S. government money market funds, as well as sovereign debt instruments issued by the U.S., the U.K., France, Sweden, and Japan.

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 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 March 29, 2026, the aggregate fair value of these derivative financial instruments that are in a net payable position was $1.1 billion, for which we have posted collateral of $1.2 billion with a corresponding amount reported in Short-term investments. As of March 29, 2026, the aggregate fair value of our derivative financial instruments that are in a net receivable position was $41 million, for which we have received collateral of $29 million with a corresponding amount reported in Short-term borrowings, including current portion of long-term debt.

B. Goodwill

As a result of the organizational changes to the commercial structure within the Biopharma operating segment effective in the first quarter of 2026 (see Note 13A), our goodwill is required to be reallocated amongst impacted reporting units. The reallocation of goodwill is a complex process that requires, among other things, determination of the fair value of each reporting unit under our old and new organizational structure and the portions being transferred. The reallocation will be completed in the current fiscal year. All goodwill continues to be assigned within the Biopharma reportable segment.

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, guarantees and indemnifications. The following outlines our legal contingencies, guarantees and indemnifications. 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. An adverse outcome could result in loss of patent protection for a product, a significant loss of revenues from a product or impairment of the value of associated assets. We are the plaintiff in the majority of these actions.
Product liability and other product-related litigation related to current or former products, which can include personal injury, consumer fraud, off-label promotion, securities, antitrust and breach of contract claims, among others, and 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, and 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, royalty payments, 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 (or those of our collaboration/licensing partners to which we have licenses or co-promotion rights), including but not limited to, those discussed below. We face 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. Some of our collaboration or licensing partners face challenges to the validity of their patent rights in non-U.S. jurisdictions. For example, in April 2022, the U.K. High Court issued a judgment finding invalid a BMS patent related to Eliquis due to expire in 2026, and this judgment is now final. Additional challenges are pending in other jurisdictions. Adverse decisions in these matters could have a material adverse effect on our results of operations. We are also party to patent damages suits in various jurisdictions pursuant to which generic drug manufacturers, payors, 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, as well as court proceedings relating to our intellectual property or the intellectual property rights of others, including challenges to such rights initiated by us. Also, if one of our patents (or one of our collaboration/licensing partner’s 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 have been challenged in inter partes review and post-grant review proceedings in the U.S. Patent and Trademark Office, as well as outside the U.S. The invalidation of any of the patents in our pneumococcal portfolio could potentially allow additional competitor vaccines, if approved, to enter the marketplace earlier than anticipated. In the event that any of the patents are found valid and infringed, a competitor’s vaccine, if approved, 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. If one of our marketed products (or a product of our collaboration/licensing partners to which we have licenses or co-promotion rights) is found to infringe valid patent rights of a third party, such third party may be awarded significant damages or royalty payments, 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

Vyndaqel-Vyndamax (tafamidis/tafamidis meglumine)

Beginning in June 2023, several generic companies notified us that they had filed ANDAs with the FDA seeking approval to market generic versions of tafamidis capsules (61 mg) or tafamidis meglumine capsules (20 mg), challenging some or all of the patents listed in the FDA’s Orange Book for Vyndamax (tafamidis) and Vyndaqel (tafamidis meglumine).

Pfizer is the sole plaintiff in actions that assert only the infringement and validity of the crystalline form patent. In March 2026, we settled the case involving Vyndaqel on terms not material to the Company. In April 2026, we settled three cases involving Vyndamax. Under the terms of the settlements, the generic companies will be permitted to launch generic versions of Vyndamax capsules on June 1, 2031, subject to the outcome of other litigation relating to Vyndamax. An additional patent infringement action involving Apotex Corp. relating to Vyndamax is ongoing in the U.S. District Court for the District of Delaware.

Actions in Which We are the Defendant

Comirnaty (tozinameran)

In August 2022, ModernaTX, Inc. (ModernaTX) and Moderna US, Inc. (Moderna) sued Pfizer, BioNTech, BioNTech Manufacturing GmbH and BioNTech US Inc. in the U.S. District Court for the District of Massachusetts, alleging that Comirnaty infringes three U.S. patents. In its complaint, Moderna stated that it is seeking damages for alleged infringement occurring after March 7, 2022. In March 2024, the U.S. Patent Office Patent Trial & Appeal Board instituted a review of two of the three patents in suit. In March 2025, the U.S. Patent Office issued a decision holding that the two Moderna patents were invalid.

In August 2022, ModernaTX filed a patent infringement action in Germany against Pfizer and certain subsidiary companies, as well as BioNTech and certain subsidiary companies, alleging that Comirnaty infringes two European patents. In March 2025, a German court found the asserted patents infringed; no decision on invalidity was rendered. In September 2022, ModernaTX filed patent infringement actions in the U.K. and in the Netherlands against Pfizer and certain subsidiary companies, as well as BioNTech and certain subsidiary companies, on the same two European patents. In its complaints, ModernaTX stated that it is seeking damages for alleged infringement occurring after March 7, 2022. In November 2023, one of the European patents was revoked by the European Patent Office and, in January 2026, that decision became final. In December 2023, the other European patent was declared invalid by a court in the Netherlands (the invalidity decision is limited to the Netherlands). In July 2024, the U.K. court revoked one patent, ruling that it was invalid, and held that the other patent was valid and infringed. In July 2025, the U.K. Court of Appeal affirmed the lower court ruling that the other patent is valid and infringed. ModernaTX has also filed additional patent infringement actions against Pfizer and BioNTech in certain other ex-U.S. jurisdictions.

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

Numerous lawsuits against 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.

In addition, 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.

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

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.

Docetaxel

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. Hospira is a wholly-owned subsidiary that we acquired in September 2015. The significant majority of the cases also name other defendants, including the manufacturer of the branded product, Taxotere. Plaintiffs seek compensatory and punitive damages. Additional lawsuits have been filed in which plaintiffs allege they developed blocked tear ducts following their treatment with Docetaxel.

In 2016, the federal cases were transferred for coordinated pre-trial proceedings to an MDL in the U.S. District Court for the Eastern District of Louisiana. In 2022, the eye injury cases were transferred for coordinated pre-trial proceedings to an MDL in the U.S. District Court for the Eastern District of Louisiana. All of the hair loss and eye injury cases filed against Hospira and Pfizer have been dismissed with prejudice.

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. In 2006, Pfizer sold the consumer business that included its Zantac OTC rights to Johnson & Johnson and transferred the assets and liabilities related to Zantac OTC to Johnson & Johnson in connection with the sale. Plaintiffs in these cases seek compensatory and punitive damages.

In February 2020, the federal actions were transferred for coordinated pre-trial proceedings to an MDL in the U.S. District Court for the Southern District of Florida (the Federal MDL Court). Plaintiffs in the MDL 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. In December 2022, the Federal MDL Court granted defendants’ Daubert motions to exclude plaintiffs’ expert testimony and motion for summary judgment on general causation, which has resulted in the dismissal of all complaints in the litigation. Plaintiffs have appealed the Federal MDL Court’s rulings.

In addition, (i) Pfizer has received service of 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 courts, alleging various state statutory and common law claims in connection with the defendants’ alleged sale of Zantac in those jurisdictions. In April 2026, the Company reached agreements with the State of New Mexico and the Mayor and City Council of Baltimore on terms not material to Pfizer. 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. Coordinated proceedings have also been created in other state courts. The large majority of the state court cases have been filed in the Superior Court of Delaware in New Castle County.

Many of these Zantac-related cases have been outstanding for a number of years. From time to time, Pfizer has explored and will continue to explore opportunistic settlements of these matters. As of May 2026, Pfizer had settled, or entered into definitive agreements or agreements-in-principle to settle, subject to certain conditions, a substantial majority of the cases filed in state courts in which the plaintiff alleges use of a Pfizer product. The remaining unresolved state court cases continue in various state courts.

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. In December 2022, the federal actions were transferred for coordinated pre-trial proceedings to an MDL in the U.S. District Court for the Southern District of New York. In March 2026, the parties reached an agreement in principle to resolve the litigation on terms not material to Pfizer. The agreement is subject to court approval.

Depo-Provera

A number of lawsuits have been filed against Pfizer and certain subsidiaries in various federal and state courts alleging that plaintiffs who used the injectable version of Depo-Provera (active ingredient medroxyprogesterone acetate, or MPA) for contraception developed meningioma. Some cases also name other defendants, including the manufacturers of generic versions

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

of injectable MPA for contraception. Plaintiffs assert claims against Pfizer relating to both Depo-Provera and generic MPA products, and seek compensatory and punitive damages. In February 2025, the federal cases were transferred for coordinated pre-trial proceedings to an MDL in the U.S. District Court for the Northern District of Florida. Also, in 2025, coordinated proceedings were established in several U.S. state jurisdictions, including California, Connecticut, Delaware, and New York.

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. In 2018, Bayer AG acquired Monsanto Company (New Monsanto), which is now a subsidiary of Bayer AG. Since the acquisition, New Monsanto has continued to defend and indemnify Pharmacia for these liabilities.

Environmental Matters

In 2009, as part of our acquisition of Wyeth, we assumed responsibility for environmental remediation at the Wyeth Holdings LLC (formerly known as Wyeth Holdings Corporation and American Cyanamid Company) discontinued industrial chemical facility in Bound Brook, New Jersey. Since that time, we have executed or have become a party to a number of administrative settlement agreements, orders on consent, and/or judicial consent decrees, with the U.S. Environmental Protection Agency, the New Jersey Department of Environmental Protection and/or federal and state natural resource trustees to perform remedial design, removal and remedial actions, and related environmental remediation activities, and to resolve alleged damages to natural resources, at the Bound Brook facility. We have accrued for the currently estimated costs of these activities.

We are also 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. In January 2022, the Court of Appeals reversed the District Court’s decision. In June 2024, the U.S. Supreme Court issued an order granting certiorari, vacating the Court of Appeals’ decision, and remanding the case to the Court of Appeals. In January 2026, the Court of Appeals reversed the District Court’s decision and, in February 2026, the defendants filed a petition seeking reconsideration by the Court of Appeals, which was denied.

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

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

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 – Comirnaty

In 2023, Pfizer and BioNTech Manufacturing GmbH initiated separate formal proceedings against the Republic of Poland, the Republic of Romania and Hungary in Belgium’s Court of First Instance of Brussels, seeking to hold those countries to their commitments for COVID-19 vaccine orders, which were placed as part of their contracts signed in 2021. In April 2026, the Court of First Instance of Brussels issued a judgment in favor of Pfizer and BioNTech against the Republic of Poland and the Republic of Romania. The proceedings against Hungary are continuing separately.

A4. Legal Proceedings––Government Investigations

Like other multi-national pharmaceutical companies, 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. These matters often involve government requests for information on a voluntary basis or through subpoenas after which the government may seek additional information through follow-up requests or additional subpoenas. 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 Antitrust Litigation

In 2019 and 2020, Attorneys General of more than 50 states and territories filed two complaints in the U.S. District Court for the District of Connecticut against a number of pharmaceutical companies, including Pfizer and Greenstone—a former Pfizer subsidiary that sold generic drugs. As to Greenstone and Pfizer, the complaints allege anticompetitive conduct in violation of federal and state antitrust laws and state consumer protection laws. The State Attorney General complaints were initially transferred to an MDL in the U.S. District Court for the Eastern District of Pennsylvania for coordinated pre-trial proceedings but were transferred back to the District of Connecticut in April 2024. The Greenstone antitrust litigation also includes civil complaints filed in federal and state court by private and governmental plaintiffs against Pfizer, Greenstone, and a number of other defendants. These related civil lawsuits assert allegations that generally overlap with those asserted by the State Attorneys General. All of the related federal lawsuits are part of the MDL pending in Pennsylvania.

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 have produced records pursuant to these requests.

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

See 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.

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 March 29, 2026, the estimated fair value of these indemnification obligations is not material to Pfizer.

In addition, in connection with our entry into certain agreements and other transactions, our counterparties may be obligated to indemnify us. For example, our global agreement with BioNTech to co-develop a mRNA-based coronavirus vaccine program aimed at preventing COVID-19 infection includes certain indemnity provisions pursuant to which each of BioNTech and Pfizer has agreed to indemnify the other for certain liabilities that may arise in connection with certain third-party claims relating to Comirnaty.

See Note 7D in our 2025 Form 10-K for information on Pfizer Inc.’s guarantee of the debt issued by Pfizer Netherlands International Finance B.V. (a wholly-owned finance subsidiary of Pfizer) in May 2025 and the debt issued by Pfizer Investment

(UNAUDITED)

Enterprises Pte. Ltd. (a wholly-owned finance subsidiary of Pfizer) in May 2023. We have also guaranteed the long-term debt of certain subsidiaries of Pfizer and certain companies that we acquired and that now are subsidiaries of Pfizer.

C. Contingent Consideration for Acquisitions

We may be required to make contingent consideration payments to sellers for certain prior Pfizer business combinations that are contingent on future events or outcomes. We also have assumed certain contingent consideration liabilities that were previously promised to sellers by a company subsequently acquired by Pfizer. See Notes 1D and 16D in our 2025 Form 10-K and Note s 2A and 7A**.

Note 13. Segment, Geographic and Other Revenue Information

A. Segment Information

Beginning in the first quarter of 2026, we manage our commercial operations through two operating segments, each led by a single manager: Biopharma and PC1. This structure reflects our current operating model following the wind-down in 2025 of the Pfizer Ignite operating segment. Biopharma is engaged in the discovery, development, manufacture, marketing, sale and distribution of biopharmaceutical products worldwide. PC1 is our contract development and manufacturing organization and a leading supplier of specialty active pharmaceutical ingredients. Biopharma is the only reportable segment. We regularly review our operating segments and the approach used by management to evaluate performance and allocate resources.

Within our Biopharma reportable segment, our commercial divisions market, sell and distribute our products, and global operating functions are responsible for the research, development, manufacturing and supply of our products. Each operating segment is supported by our global corporate enabling functions and other corporate functions. At the beginning of 2026, we made changes in our commercial organization, which included the transition of certain off-patent branded and generic sterile injectables and biosimilars primarily from the Specialty Care and Oncology product portfolios to a new Global Hospital and Biosimilars Division within our Biopharma reportable segment to support our continued focus on commercial execution.

*Other Business Activities and Reconciling Items––*Other business activities include the operating results of PC1 and our former operating segment, Pfizer Ignite, as well as certain pre-tax costs not allocated to our operating segment results, such as costs associated with corporate enabling functions and other corporate costs. Reconciling items include the following items, transactions and events that are not allocated to our operating segments: (i) all amortization of intangible assets; (ii) acquisition-related items; and (iii) certain significant items, representing substantive and/or unusual, and in some cases recurring, items that are evaluated on an individual basis by management and that, either as a result of their nature or size, would not be expected to occur as part of our normal business on a regular basis.

*Segment Assets––*We manage our assets on a total company basis, not by operating segment, as our operating assets are shared or commingled. Therefore, our CODM does not regularly review any asset information by operating segment and, accordingly, we do not report asset information by operating segment.
