### 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 and six months ended May 24, 2026 and May 25, 2025, and for U.S. subsidiaries is as of and for the three and six months ended June 28, 2026 and June 29, 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](#ic3daa1857b29415b9ca41f62a8bb3d9e_133).

#### 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) | June 28,2026 | December 31, 2025 |
| --- | --- | --- |
| Reserve against Trade accounts receivable, net of allowance for doubtful accounts | $1,741 | $1,803 |
| Other current liabilities: |  |  |
| Accrued rebates | 9,293 | 7,909 |
| Other accruals | 763 | 750 |
| Other noncurrent liabilities | 332 | 1,204 |
| Total accrued rebates and other sales-related accruals | $12,128 | $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 and six months ended June 28, 2026 and June 29, 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, Sale of Investment and Research and Development Arrangement

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

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

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 CVRs and $475 million for employee stock awards related to pre-acquisition service.

In connection with this business combination, we provisionally recorded: (i) $7.9 billion of identifiable intangible assets, net, consisting of IPR&D, (ii) $2.1 billion of Goodwill, (iii) $1.6 billion of net deferred tax liabilities, and (iv) $643 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

Sale of Investment in 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. We received $1.875 billion in cash proceeds. See [Note](#ic3daa1857b29415b9ca41f62a8bb3d9e_61)[4](#ic3daa1857b29415b9ca41f62a8bb3d9e_61) and Note 2C in our 2025 Form 10-K.

Dividend income from our investment in ViiV, recorded in Other (income)/deductions—net, was $98 million and $73 million for the three months ended June 28, 2026 and June 29, 2025, respectively, and $180 million and $111 million for the six months ended June 28, 2026 and June 29, 2025, respectively (see [Note 4](#ic3daa1857b29415b9ca41f62a8bb3d9e_61)).

D. Research and Development Arrangement

Research and Development Funding Arrangement with Abingworth—In June 2026, we entered into an arrangement with Abingworth under which we will receive up to a total of $300 million in 2026 through 2029 to co-fund our quarterly development costs for a specified treatment. As there is a substantive transfer of risk to the financial partner, the development funding is recognized by us as an obligation to perform contractual services. We are recognizing the funding as a reduction of Research and development expenses using an attribution model over the period of the related expenses. The reduction to Research and development expenses for the second quarter of 2026 was $26 million. If successful, upon regulatory approval in the U.S. for the indication based on the applicable clinical trial, Abingworth will be eligible to receive an approval-based milestone payment of up to $180 million, contingent upon the successful results of the clinical trial and payable over a period of approximately eighteen months. Following potential regulatory approval, Abingworth will be eligible to receive sales-based milestone payments of up to $420 million in total, based on the achievement of certain levels of cumulative applicable net sales and payable over a period of approximately three years, as well as royalties based on mid-single digit percentage of the applicable net sales, subject to an annual cap. The net present value of the approval-based milestone payments and sales-based milestone payments, when earned, would be recorded as intangible assets and amortized to Amortization of intangible assets over the shorter of the term of the agreement or the estimated commercial life of the product. Accretion of interest on the liabilities to pay Abingworth will be recognized as interest expense in Other (income)/deductions—net. Royalties on net sales will be recorded as Cost of sales when the related product sales occur.

### 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 $3.4 billion is associated with our Biopharma segment.

In the third quarter of 2026, we identified additional productivity enhancements from technology and simplification efforts across our commercial, R&D and enabling functions designed to further reduce costs in SI&A. We expect one-time costs to achieve the additional savings to be incurred through 2029 and to total approximately $2.0 billion, primarily representing cash

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

expenditures for digital enablement, implementation and severance of which $800 million 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 $7.3 billion of which $4.8 billion is associated with the Biopharma segment.

From the start of this program through June 28, 2026, we incurred total costs of $4.9 billion, of which $3.8 billion is associated with our Biopharma segment (including $3.3 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.

In the third quarter of 2026, we announced the next phase of the program, with a focus on network structure changes, product portfolio enhancements and additional operational efficiencies. The one-time costs to achieve the savings associated with this phase of the program are expected to be approximately $4.0 billion, substantially all associated with our Biopharma segment, with approximately 60% of non-cash expenditures for accelerated depreciation and asset write-downs and 40% of cash expenditures for severance, implementation and exit costs. The costs to achieve these savings are expected to be incurred through 2029.

We expect costs associated with both phases of this program to total approximately $5.4 billion, substantially all of which is associated with the Biopharma segment.

From the start of this program through June 28, 2026, we incurred total costs of $1.1 billion, substantially all of which relates to our Biopharma segment (including $824 million of restructuring charges). The costs were recorded primarily through 2025, with cash outlays expected primarily through 2029.

(a)The amounts for the second quarter and first six months of 2026 and 2025 primarily include certain product liability and other legal expenses.

(b)The amounts for the second quarter and first six months of 2026 represent intangible asset impairment charges associated with our Biopharma segment, composed of: (i) $3.8 billion in impairments of IPR&D assets, associated with a Phase 3 study for sigvotatug vedotin for the second line treatment of metastatic non-squamous NSCLC, reflecting unfavorable clinical trial results, and (ii) $525 million for Oxbryta (voxelotor) developed technology rights, after engaging with the FDA in July 2026 to discuss their assessment of data and analyses, and it was determined there was no viable pathway to return Oxbryta to the market in the U.S. The amount for the first six months of 2025 primarily included an intangible asset impairment charge associated with our Biopharma segment of $210 million for a Phase 2 indefinite-lived out-licensed asset that was discontinued by our out-licensing partner.

(c)See [Note](#ic3daa1857b29415b9ca41f62a8bb3d9e_49)[2C](#ic3daa1857b29415b9ca41f62a8bb3d9e_49).

(e)The amounts for the second quarter and first six months of 2026 include, among other things, dividend income of $98 million and $180 million, respectively, from our previous investment in ViiV. The amounts for the second quarter and first six months of 2025 included, among other things, dividend income of $73 million and $111 million, respectively, from our previous investment in ViiV.

**Additional information about the intangible assets that were impaired during 2026 follows:**

| (MILLIONS) | Fair Value(a) / Amount | Fair Value(a) / Level 1 | Fair Value(a) / Level 2 | Fair Value(a) / Level 3 | Six Months Ended / June 28, 2026 / Impairment |
| --- | --- | --- | --- | --- | --- |
| IPR&D(b) | $5,600 | — | — | $5,600 | $3,800 |
| Developed technology rights(b) | — | — | — | — | 525 |
| Total | $5,600 | — | — | $5,600 | $4,325 |

(a)The fair value amount reflects the remaining fair value for the asset that has been impaired as of the date of impairment, as this asset is not measured at fair value on a recurring basis. See Note 1E in our 2025 Form 10-K.

(b)Reflects intangible assets written down to fair value in 2026. Fair value was determined using the income approach, specifically the multi-period excess earnings method, also known as the discounted cash flow method. We started with a forecast of all the expected net cash flows for the asset and then applied an asset-specific discount rate to arrive at a net present value amount. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of competitive, legal and/or regulatory factors on the product; and assumptions about the probability of technical and regulatory success (PTRS) of ongoing clinical trials, the discount rate, which seeks to reflect the various risks inherent in the projected cash flows; and the tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

For additional information on identifiable intangible assets, see [Note 9](#ic3daa1857b29415b9ca41f62a8bb3d9e_109).

### Note 5. Tax Matters

A. Taxes on Income/(Loss) from Continuing Operations

Our effective tax rate for continuing operations was 62.4% for the second quarter of 2026, compared to 4.6% for the second quarter of 2025, and was 2.1% for the first six months of 2026, compared to (0.8)% for the first six months of 2025. The higher effective tax rate for the second quarter of 2026, compared to the second quarter of 2025, reflects a tax benefit on the pre-tax loss resulting from changes in the jurisdictional mix of earnings, primarily due to intangible asset impairments. The higher effective tax rate for the first six months of 2026, compared to the first six months of 2025, was primarily due to changes in the jurisdictional mix of earnings as well as the non-recurrence of favorable global income tax resolutions.

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

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.

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 by the IRS; tax years 2023-2026 are open but not under audit, and all other tax years are closed. We also 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 $60 billion as of June 28, 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 June 28, 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 June 28, 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

(UNAUDITED)

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.

COS = Cost of Sales, included in Cost of sales in the condensed consolidated statements of operations. OCI = Other comprehensive income/(loss), included in the condensed consolidated statements of comprehensive income/(loss).

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

- a net loss of $6 million in the second quarter of 2026;
- a net loss of $20 million in the first six months of 2026;
- a net gain of $30 million in the second quarter of 2025; and
- a net gain of $93 million in the first six months of 2025.

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 $72 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 17 years and relates to foreign currency debt.

(UNAUDITED)

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 June 28, 2026, the aggregate fair value of these derivative financial instruments that are in a net payable position was $880 million, for which we have posted collateral of $935 million with a corresponding amount reported in Short-term investments. As of June 28, 2026, the aggregate fair value of our derivative financial instruments that are in a net receivable position was $109 million, for which we have received collateral of $90 million with a corresponding amount reported in Short-term borrowings, including current portion of long-term debt.

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](#ic3daa1857b29415b9ca41f62a8bb3d9e_67).

#### 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

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

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, BMS is facing patent challenges relating to Eliquis in certain ex-U.S. 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 (or may be impacted by) 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 exclusivity rights (or one of our collaboration/licensing partner’s patents/rights) 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, in April 2026, Teva GmbH brought suit against the EMA seeking to annul the EMA’s decision refusing to validate Teva’s marketing authorisation application for a generic tafamidis product, which suit is ongoing.

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 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). Scripps Research Institute (Scripps) owns the composition of matter patent and the method of treatment patents covering the products, and Pfizer is the exclusive licensee. Pfizer separately owns the crystalline form patent. Beginning in 2023, we and Scripps 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 in suit. In May 2026, we settled patent litigations relating to Vyndamax and Vyndaqel with all generic filers except Apotex Corp. For additional information, see A5. Legal Proceedings––Matters Resolved During the First Six Months of 2026. The patent infringement action involving Apotex Corp. relating to Vyndamax is ongoing in the U.S. District Court for the District of Delaware.

Oxbryta (voxelotor)

In 2024, Zydus Pharmaceuticals (USA) Inc., Zydus Lifesciences Limited, and Zydus Worldwide DMCC (collectively, Zydus) and MSN Pharmaceuticals Inc. and MSN Laboratories Private Ltd. (collectively, MSN) separately notified us that they had filed ANDAs with the FDA seeking approval to market generic versions of voxelotor tablets, challenging some of the patents listed in the FDA’s Orange Book for Oxbryta (voxelotor tablets in 300 mg and 500 mg strengths and/or for oral suspension) on non-infringement grounds. In 2024, we filed patent infringement actions against both generic filers in the U.S. District Court for the District of Delaware, asserting the validity and infringement of the challenged patents. Zydus and MSN have not challenged our composition of matter patents or method of treatment patents for Oxbryta. On July 31, 2026, Pfizer notified the FDA that it is voluntarily withdrawing the NDAs for Oxbryta.

Nurtec (rimegepant)

Beginning in 2024, several generic manufacturers notified us that they had filed ANDAs with the FDA seeking approval to market generic versions of rimegepant orally disintegrating tablets, claiming noninfringement and/or challenging the validity of some or all of the patents listed in the FDA’s Orange Book for Nurtec (rimegepant orally disintegrating tablets Eq 75 mg base). In May 2024, we filed patent infringement actions against all of the generic filers in the U.S. District Court for the District of Delaware.

Xtandi (enzalutamide)

Beginning in 2024, several generic companies notified us and Astellas that they had filed ANDAs with the FDA seeking approval to market generic versions of Xtandi, challenging some or all of the patents listed in the FDA’s Orange Book for

Xtandi. Beginning in 2024, we and Astellas brought patent infringement actions against the generic filers in the U.S. District Court for the District of New Jersey, asserting the validity and infringement of the patents in suit.

Cibinqo (abrocitinib)

In March 2026, Micro Labs Limited and Micro Labs USA, Inc. (collectively, Micro Labs), Changzhou Pharmaceutical Factory (Changzhou), and Biocon Limited, Biocon Pharma Limited and Biocon Pharma, Inc. (collectively, Biocon) notified us that they filed ANDAs with the FDA seeking approval to market generic versions of abrocitinib and challenging all three patents listed in the Orange Book. In April 2026, we filed patent infringement actions against Micro Labs, Changzhou and Biocon in the U.S. District Court for the District of Delaware asserting the infringement and validity of the challenged patents.

Actions in Which We are the Defendant

Comirnaty (tozinameran)

In 2022, ModernaTX, Inc. (ModernaTX) and Moderna US, Inc. (Moderna) sued several Pfizer and BioNTech entities in the U.S. District Court for the District of Massachusetts, alleging that Comirnaty infringes three U.S. patents and seeking monetary damages. ModernaTX is seeking damages for alleged infringement occurring after March 7, 2022. In 2024, the case was stayed pending the outcome of separate inter partes review actions brought at the U.S. Patent Office (USPTO) seeking to invalidate two of the asserted Moderna patents. In March 2025, the USPTO found the two Moderna patents invalid.

In 2022, ModernaTX filed a patent infringement action in Germany against several Pfizer and BioNTech entities, alleging that Comirnaty infringes two European patents. In March 2025, the German Court found the asserted patents infringed; no decision on invalidity was rendered. In 2022, ModernaTX filed patent infringement actions in the U.K. and the Netherlands against several Pfizer and BioNTech entities, on the same two European patents. ModernaTX is seeking damages for alleged infringement occurring after March 7, 2022. In 2024, the U.K. Court revoked one of the two patents, while upholding the other as valid and infringed. Separately, the European Patent Office (EPO) revoked the same patent and upheld the same patent as the U.K. Court. ModernaTX has also filed additional patent infringement actions against Pfizer and BioNTech in certain other ex-U.S. jurisdictions.

In 2023, Arbutus Biopharma Corporation (Arbutus) and Genevant Sciences GmbH (Genevant) filed a complaint in the U.S. District Court for the District of New Jersey against Pfizer and BioNTech entities alleging that Comirnaty and its manufacture infringe five U.S. patents, and seeking unspecified monetary damages. Additional patent infringement actions between Genevant/Arbutus and Pfizer/BioNTech are ongoing in certain other ex-U.S. jurisdictions.

In April 2024, GlaxoSmithKline Biologicals SA and GlaxoSmithKline LLC (collectively, GSK Group) sued several Pfizer and BioNTech entities in the U.S. District Court for the District of Delaware, alleging that Comirnaty infringes five U.S. patents and seeking unspecified monetary damages. In August 2024, GSK Group added three additional U.S. patents to the case. In July 2025, GSK Group sued several Pfizer and BioNTech entities in both Ireland and the Unified Patent Court, alleging that Comirnaty infringes three European patents. In September 2025, Pfizer and BioNTech filed a revocation action in the U.K. with respect to the three patents asserted in the Irish and United Patent Court cases.

In January 2025, Promosome LLC filed a complaint in the Unified Patent Court, Local Division Munich, against several Pfizer and BioNTech entities, alleging that Comirnaty infringes a European patent that is in force only in France, Germany and Sweden, and seeking unspecified monetary damages in connection with the manufacture and sale of Comirnaty in France, Germany and Sweden. In July 2026, the Court issued a decision finding the Promosome LLC patent not infringed and invalid.

In January 2026, Bayer Cropscience LLC, Monsanto Company and Monsanto Technology, LLC filed a complaint in the U.S. District Court for the District of Delaware against Pfizer and BioNTech, BioNTech Manufacturing GmbH and BioNTech US Inc, alleging that Comirnaty infringes one U.S. patent and seeking unspecified monetary damages.

In July 2026, Translate Bio, Inc., Translate Bio MA, Inc., Sanofi Vaccines US Inc., and VaxServe, Inc. (collectively, Sanofi) filed a complaint in the U.S. District Court for the District of New Jersey against Pfizer and Pharmacia & Upjohn Co. LLC, alleging that Comirnaty infringes eight U.S. patents and seeking unspecified monetary damages.

Paxlovid

In 2022, Enanta Pharmaceuticals, Inc. (Enanta) filed a complaint in the U.S. District Court for the District of Massachusetts against Pfizer alleging that the active ingredient in Paxlovid, nirmatrelvir, infringes a U.S. patent issued in 2022, and seeking unspecified monetary damages. In 2024, the District Court issued an order granting Pfizer’s motion for summary judgment, finding Enanta’s patent invalid. In June 2026, the U.S. Court of Appeals for the Federal Circuit affirmed the District Court’s decision.

In August 2025, Enanta filed a patent infringement complaint in the Unified Patent Court, Local Division Munich, against Pfizer alleging that the active ingredient in Paxlovid, nirmatrelvir, infringes a European patent issued in August 2025, and seeking unspecified monetary damages.

Matters Involving Pfizer and its Collaboration/Licensing Partners

Orgovyx (relugolix)

Beginning in January 2025, several generic companies notified us that they had filed ANDAs with the FDA seeking approval to sell a generic form of relugolix (Orgovyx), and challenging one or more patents listed in the FDA’s Orange Book for Orgovyx which are licensed to Pfizer. In March 2025, we, along with Sumitomo Pharma Switzerland GBBH, Sumitomo Pharma America, Inc., Takeda and Takeda Pharmaceuticals International AG jointly filed separate patent infringement actions in the U.S. District Court for the District of Delaware against the generic companies, asserting the infringement and validity of the patents in suit.

Eliquis (apixaban)

In December 2025, BMS and Pfizer filed a patent infringement action in the U.S. District Court for the District of Delaware against Azurity Pharmaceuticals, Inc. (Azurity), alleging that Azurity’s proposed generic apixaban product would infringe a formulation patent expiring in 2031.

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.

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.

#### 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, 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.

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

(UNAUDITED)

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 final 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 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. In June 2026, we reached an agreement-in-principle with plaintiff leadership in the Depo-Provera MDL that we expect to resolve a substantial majority of the pending MDL cases on terms that are not material to the Company’s liquidity or financial condition. 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.

(UNAUDITED)

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 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.

A5. Legal Proceedings––Matters Resolved During the First Six Months of 2026

During the first six months of 2026, certain matters, including the matter discussed below, were resolved or became the subject of definitive settlement agreements or settlement agreements-in-principle.

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

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). Scripps Research Institute (Scripps) owns the composition of matter patent and the method of treatment patents covering the products, and Pfizer is the exclusive licensee. Pfizer separately owns the crystalline form patent. Beginning in August 2023, we and Scripps 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 in suit. Pfizer was 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.

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 June 28, 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 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 [Notes 2A](#ic3daa1857b29415b9ca41f62a8bb3d9e_49) and [7A](#ic3daa1857b29415b9ca41f62a8bb3d9e_76).

### 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. Effective January 1, 2026, the commercial structure within our Biopharma reportable segment is as follows:

- Pfizer U.S. Commercial Division includes the U.S. commercial organization covering Pfizer’s entire product portfolio except for the Global Hospital and Biosimilars organization, as well as the Global Access & Value, Global Chief Marketing Office and Primary Care and Specialty Care U.S. Medical Affairs organizations.

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

- Pfizer International Commercial Division includes the ex-U.S. commercial and medical affairs organizations covering Pfizer’s entire product portfolio in all international markets except for the Global Hospital and Biosimilars organization in certain international markets.
- Global Hospital and Biosimilars Division includes the commercial organization covering Pfizer’s Hospital and Biosimilars product portfolio of off-patent branded and generic sterile injectables and biosimilars except in China, Hong Kong, and certain other international markets, which are part of the Pfizer International Commercial Division.

Other Business Activities and Reconciling Items––Other business activities include the operating results of PC1, 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. Total assets were $201 billion as of June 28, 2026 and $208 billion as of December 31, 2025.

and $965 million, respectively, as of June 28, 2026, which includes amounts received in advance and deferred, as well as amounts that will be invoiced as we deliver these products to our customers in future periods. Of these amounts, current contract terms provide for expected delivery of product with contracted revenue primarily from 2026 through 2028, the timing of which may be renegotiated. Remaining performance obligations are based on foreign exchange rates as of the end of our fiscal second quarter of 2026 and exclude arrangements with an original expected contract duration of less than one year. Remaining performance obligations associated with contracts for other products and services were not significant as of June 28, 2026 or December 31, 2025.

Deferred Revenues––Our deferred revenues primarily relate to advance payments received or receivable from various government or government sponsored customers for supply of Paxlovid and Comirnaty. The deferred revenues related to Paxlovid and Comirnaty totaled $1.4 billion as of June 28, 2026, with $521 million and $855 million recorded in current liabilities and noncurrent liabilities, respectively. The deferred revenues related to Paxlovid and Comirnaty totaled $1.5 billion as of December 31, 2025, with $689 million and $826 million recorded in current liabilities and noncurrent liabilities, respectively. The decrease in Paxlovid and Comirnaty deferred revenues during the first six months of 2026 was primarily driven by amounts recognized in Product revenues as we delivered the products to our customers. During the second quarter and the first six months of 2026, we recognized revenue of approximately $75 million and $133 million, respectively, that was included in the balance of Comirnaty and Paxlovid deferred revenues as of December 31, 2025. The Paxlovid and Comirnaty deferred revenues as of June 28, 2026 will be recognized in Product revenues proportionately as we transfer control of the products to our customers and satisfy our performance obligations under the contracts, with the amounts included in current liabilities expected to be recognized in Product revenues within the next 12 months, and the amounts included in noncurrent liabilities expected to be recognized in Product revenues primarily from 2027 through 2028. Deferred revenues associated with contracts for other products were not significant as of June 28, 2026 or December 31, 2025.

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

GENERAL

The following MD&A is intended to assist the reader in understanding our financial condition and results of operations, including an evaluation of the amounts and certainty of cash flows from operations and from outside sources, and is provided as a supplement to and should be read in conjunction with the condensed consolidated financial statements and related notes in [Item 1. Financial Statements](#ic3daa1857b29415b9ca41f62a8bb3d9e_16) in this Form 10-Q.

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 because 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.

OVERVIEW OF OUR PERFORMANCE, OPERATING AND GLOBAL ECONOMIC ENVIRONMENT

Our Business––Pfizer Inc. is a research-based, global biopharmaceutical company. We apply science and our global resources to bring therapies to people that extend and significantly improve their lives through the discovery, development, manufacture, marketing, sale and distribution of biopharmaceutical products worldwide.

Segments––Beginning in the first quarter of 2026, we manage our commercial operations through a global structure consisting of two operating segments: Biopharma and PC1. Biopharma is the only reportable segment. See [Note 13A](#ic3daa1857b29415b9ca41f62a8bb3d9e_133).

For additional information about our business, strategy and operating environment, see the Item 1. Business section and the Overview of Our Performance, Operating Environment, Strategy and Outlook section within MD&A of our 2025 Form 10-K.

Restructuring Programs

Realigning Our Cost Base Program––In the third quarter of 2026, we announced $1.0 billion of additional anticipated net cost savings associated with this program driven by further productivity enhancements from technology and simplification efforts across our commercial, R&D and enabling functions. These additional net savings are expected to further reduce costs in SI&A and be realized from 2027 through 2029. We expect one-time costs to achieve the additional savings to be incurred through 2029 and to total approximately $2.0 billion.

Manufacturing Optimization Program––In the third quarter of 2026, we announced the next phase of our multi-year program designed to reduce our cost of goods sold focused on network structure changes, product portfolio enhancements and additional operational efficiencies which is expected to deliver additional anticipated savings of approximately $1.5 billion through 2029, some of which is expected to begin being realized in 2027. The one-time costs to achieve the savings associated with this phase of the program are expected to be approximately $4.0 billion, with approximately 60% of non-cash expenditures. The costs to achieve these savings are expected to be incurred through 2029.

For a description of anticipated savings related to these programs, see the [Costs and Expenses––Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiatives](#ic3daa1857b29415b9ca41f62a8bb3d9e_175) section within MD&A and [Note 3](#ic3daa1857b29415b9ca41f62a8bb3d9e_55) for the anticipated and actual costs of these programs.

Our Business Development Initiatives––We are committed to strategically capitalizing on growth opportunities, primarily by advancing our own product pipeline and maximizing the value of our existing products, but also through various business development activities. For a description of the more significant recent transactions through February 26, 2026, the filing date of our 2025 Form 10-K, see Note 2 in our 2025 Form 10-K. In addition, for a discussion of our acquisition of Metsera in November 2025 and other recent business development initiatives see [Note 2](#ic3daa1857b29415b9ca41f62a8bb3d9e_49), as well as the following:

Collaboration Agreement with Innovent––In May 2026, we entered into a strategic global licensing and collaboration agreement with Innovent, a Chinese biopharmaceutical company, for the research and development of 12 early-stage and de novo cancer medicines. The partnership includes licensing, co-development, and co-commercialization opportunities across a diverse portfolio of antibody-drug conjugates (ADCs) with novel differentiated payloads and multi-specific antibodies. Under the terms of the agreement, Innovent received a $650 million upfront payment and is eligible for up to $9.85 billion in development, regulatory and commercial milestone payments. Additionally, Innovent will receive up to double-digit royalties on sales of each licensed product if approved. For the four programs to be co-developed and co-commercialized by Pfizer and Innovent, the two companies will share the profits in the U.S., the U.K., and the European Union. The transaction closed on July 10, 2026.

Our Second Quarter and First Six Months of 2026 Performance

Total Revenues––Total revenues increased $381 million, or 3%, in the second quarter of 2026 to $15.0 billion from $14.7 billion in the second quarter of 2025, reflecting an operational increase of $164 million, or 1%, as well as a favorable impact of foreign exchange of $217 million, or 1%. The operational increase was driven by an increase in revenues for Eliquis, Padcev, the Vyndaqel family, Lorbrena and several other products across categories, partially offset by a decline in COVID-19 product revenues and several other products across categories. Excluding contributions from Comirnaty and Paxlovid, Total revenues increased 5% operationally.

Total revenues increased $1.1 billion, or 4%, in the first six months of 2026 to $29.5 billion from $28.4 billion in the first six months of 2025, reflecting an operational increase of $469 million, or 2%, as well as a favorable impact of foreign exchange of $648 million, or 2%. The operational increase was driven by an increase in revenues for Eliquis, Padcev, the Vyndaqel family, Lorbrena, Nurtec ODT/Vydura, Oncology biosimilars and several other products across categories, partially offset by a decline in COVID-19 product revenues and several other products across categories. Excluding contributions from Comirnaty and Paxlovid, Total revenues increased 6% operationally.

See the [Total Revenues by Geography](#ic3daa1857b29415b9ca41f62a8bb3d9e_163) and [Total Revenues––Selected Product Discussion](#ic3daa1857b29415b9ca41f62a8bb3d9e_172) sections within MD&A for more information, including a discussion of key drivers of our revenue performance for certain products.

Income/(Loss) from Continuing Operations Before Provision/(Benefit) for Taxes on Income/(Loss)–– Loss from continuing operations before provision/(benefit) for taxes on income/(loss) in the second quarter of 2026 was $653 million, compared to income of $3.0 billion in the second quarter of 2025, primarily due to (i) charges for intangible asset impairments and certain legal matters (both recorded in Other (income)/deductions––net) and (ii) increases in Restructuring charges and certain acquisition-related costs, Research and development expenses and Cost of sales, partially offset by (iii) a net gain in 2026 from the sale of our previous investment in ViiV (recorded in Other (income)/deductions––net), and (iv) higher revenues.

The decrease in Income from continuing operations before provision/(benefit) for taxes on income of $3.3 billion, to $2.5 billion in the first six months of 2026 from $5.8 billion in the first six months of 2025, was primarily due to (i) charges for intangible asset impairments and certain legal matters, and increases in the fair value of our contingent consideration liabilities (all recorded in Other (income)/deductions––net) and (ii) increases in Cost of sales and Research and development expenses, partially offset by (iii) a net gain in 2026 from the sale of our previous investment in ViiV (recorded in Other (income)/deductions––net), and (iv) higher revenues.

See the [Analysis of the Condensed Consolidated Statements of Operations](#ic3daa1857b29415b9ca41f62a8bb3d9e_160) section within MD&A and [Notes](#ic3daa1857b29415b9ca41f62a8bb3d9e_55)[#ic3daa1857b29415b9ca41f62a8bb3d9e_55](#ic3daa1857b29415b9ca41f62a8bb3d9e_55)[3](#ic3daa1857b29415b9ca41f62a8bb3d9e_55) and [4](#ic3daa1857b29415b9ca41f62a8bb3d9e_61). For information on our tax provision and effective tax rate, see the [Provision/(Benefit) for Taxes on Income/(](#ic3daa1857b29415b9ca41f62a8bb3d9e_181)[L](#ic3daa1857b29415b9ca41f62a8bb3d9e_181)[oss)](#ic3daa1857b29415b9ca41f62a8bb3d9e_181) section within MD&A and [Note 5](#ic3daa1857b29415b9ca41f62a8bb3d9e_67).

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. See also the Item 1. Business––Government Regulation and Price Constraints and Item 1A. Risk Factors sections, and the Overview of Our Performance, Operating Environment, Strategy and Outlook––Our Operating Environment section of the MD&A of our 2025 Form 10-K.

Intellectual Property Rights and Collaboration/Licensing Rights––The loss, expiration or invalidation of intellectual property rights, patent litigation settlements and judgments, and the expiration of co-promotion and licensing rights can have a material adverse effect on our revenues. We anticipate a significant reduction of revenue from patent-based or regulatory exclusivity expiries in 2026 through 2030 as several of our in-line products experience these expirations, with the rate of the reduction of revenues from patent-based or regulatory exclusivity expiries expected to significantly accelerate over the next few years. In 2026, we now expect an unfavorable revenue impact from patent-based or regulatory exclusivity expiries of approximately $1.1 billion.

For additional information on patent rights we consider most significant to our business as a whole, including U.S., major Europe and Japan basic product patent expiration years, see the Item 1. Business––Patents and Other Intellectual Property Rights section of our 2025 Form 10-K. For a discussion of recent developments with respect to patent litigation involving certain of our products, see [Notes 12A1](#ic3daa1857b29415b9ca41f62a8bb3d9e_127) and [12A5](#ic3daa1857b29415b9ca41f62a8bb3d9e_127).

Regulatory Environment/Pricing and Access––Government and Other Payor Group Pressures––Pricing and access pressures from governments globally, as well as private third-party payors in the U.S., continue to impact our global operations. With respect to the U.S., we expect to see continued focus by the U.S. government and states on regulating drug pricing and access to medicine, including but not limited to, international reference pricing, including Most-Favored-Nation (MFN) drug pricing. We continue to monitor and evaluate the implementation of the IRA, including the Medicare Drug Price Negotiation Program (MDPNP) and its government-set Maximum Fair Price (MFP) which became effective for Eliquis on January 1, 2026. Negotiated prices for Ibrance and Xtandi are effective in 2027. While Xeljanz remains a selected drug through 2028, the Centers for Medicare and Medicaid Services has determined that bona fide marketing of a generic version of Xeljanz still exists. Accordingly, no MFP for Xeljanz will be finalized or take effect. The IRA also made significant changes to the Medicare

Part D benefit design (IRA Medicare Part D Redesign), which took effect beginning in 2025. We do not expect a material, incremental impact from the IRA Medicare Part D Redesign in 2026 versus the baseline set in 2025. In addition, changes to the Medicaid Drug Rebate Program or the 340B Program, including legal or legislative developments at the federal or state level with respect to the 340B Program, could have a material impact on our business. See the Item 1. Business––Pricing Pressures and Managed Care Organizations and ––Government Regulation and Price Constraints and the Item 1A. Risk Factors––Pricing and Reimbursement sections, and the Overview of Our Performance, Operating Environment, Strategy and Outlook––Our Operating Environment section of the MD&A of our 2025 Form 10-K and The Global Economic Environment––Global Trade Environment section below.

Policy/Regulatory Environment––New and potential policy, regulatory or other changes from the U.S. Presidential administration, Congress and states, including, among others, increased, decreased, withdrawn or new regulatory requirements, including changes in requirements for licensure, changes, delays or failure to receive recommendations, reimbursement and regulatory approvals and coverage for our vaccines and medicines, as well as potential impacts on our activities in markets outside of the U.S., could have a material adverse effect on our business, earnings, cash flows, liquidity and financial guidance.

Product Supply––We periodically encounter supply delays, disruptions and shortages, including due to voluntary product recalls and natural or man-made disasters.

We have not seen a significant disruption of our supply chain in the first six months of 2026 and through the date of filing of this Form 10-Q, and all of our manufacturing sites globally have continued to operate at or near normal levels. We continue to monitor potential supply chain impacts from geopolitical and trade developments. We do not anticipate the availability of raw materials to have a significant impact on our operations in 2026, but are monitoring potential supply chain disruptions as a result of ongoing geopolitical and trade negotiations, which could, among other things, impact costs. For information on risks related to product manufacturing, see the Item 1A. Risk Factors––Product Manufacturing, Sales and Marketing Risks section of our 2025 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 economic cycles as well as broader geopolitical and regulatory developments. See the Item 1A. Risk Factors—Global Operations section of our 2025 Form 10-K, as well as the Overview of Our Performance, Operating Environment, Strategy and Outlook––The Global Economic Environment section of the MD&A of our 2025 Form 10-K.

Global Trade Environment––Issued or future executive orders or other new or changes in laws, regulations or policies regarding tariffs or other trade or foreign policy, could have a material adverse effect on our business, earnings, cash flow, liquidity and financial guidance. While the U.S. Supreme Court’s February 2026 decision related to executive authority to impose tariffs under the International Emergency Economic Powers Act (IEEPA) did not have a material impact on our consolidated financial statements, the regulatory landscape continues to evolve. Specifically, on April 2, 2026, the U.S. Government announced Section 232 tariffs on imported patented pharmaceuticals and their ingredients, up to a 100% duty to address national security concerns regarding supply chain reliance (the April 2, 2026 Section 232 Executive Order). These measures, featuring exemptions for commitments to onshore and invest in U.S. manufacturing, became effective for Pfizer on July 31, 2026. We have reached final binding agreements with the U.S. Government, ratifying the arrangements first announced in September 2025. Under these agreements, we have voluntarily committed to implement measures designed to make certain drug prices for U.S. patients more comparable to those in other developed countries, allow U.S. patients to purchase certain medicines at significant discounts to current retail prices and further invest in our U.S. manufacturing. Pursuant to the agreements, the applicable tariff rate under the April 2, 2026 Section 232 Executive Order for Pfizer products will be zero until January 20, 2029. We will continue to monitor developments and any potential impacts on our future financial results and business. For additional information on risks related to our global operations and changes in laws, see the Item 1A. Risk Factors—Global Operations and ––Changes in Laws and Accounting Standards sections of our 2025 Form 10-K.

### SIGNIFICANT ACCOUNTING POLICIES AND APPLICATION OF CRITICAL ACCOUNTING ESTIMATES AND ASSUMPTIONS

For a description of our significant accounting policies, see Note 1 in our 2025 Form 10-K. Of these policies, the following are considered critical to an understanding of our consolidated financial statements as they require the application of the most subjective and the most complex judgments: Acquisitions (Note 1D); Fair Value (Note 1E); Revenues (Note 1G); Long-Lived Assets (Note 1M); Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiatives (Note 1N); Income Taxes (Note 1Q); Pension and Postretirement Benefit Plans (Note 1R); and Legal and Environmental Contingencies (Note 1S).

For a discussion about the critical accounting estimates and assumptions impacting our consolidated financial statements, see the Significant Accounting Policies and Application of Critical Accounting Estimates and Assumptions section within MD&A of our 2025 Form 10-K. See also Note 1C in our 2025 Form 10-K for a discussion about the risks associated with estimates and assumptions.

(a)Includes revenues associated with the wind-down of our former Pfizer Ignite operating segment, which were not material in all periods presented. We reclassified prior period amounts to conform to the current period presentation.

Product 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 the related obligations and, as such, knowledge and judgment are required when estimating the impact of these product 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 product revenue deductions:**

| (MILLIONS) | Three Months Ended / June 28,2026 | Three Months Ended / June 29,2025 | Six Months Ended / June 28,2026 | Six Months Ended / June 29,2025 |

Second Quarter of 2026 vs. Second Quarter of 2025 and First Six Months of 2026 vs. First Six Months of 2025

Cost of Sales

Cost of sales increased $314 million in the second quarter of 2026, primarily due to:

- a $130 million unfavorable change in sales mix;
- an increase of $90 million, due to higher amortization of the fair value step-up of acquired inventory, driven primarily by the Oxbryta impairment; and
- a $60 million unfavorable impact of foreign exchange.

The increase in Cost of sales as a percentage of revenues in the second quarter of 2026 was primarily driven by an unfavorable change in sales mix and higher amortization of the fair value step-up of acquired inventory, primarily driven by the Oxbryta impairment.

Cost of sales increased $1.0 billion in the first six months of 2026, primarily due to:

- the non-recurrence of a favorable revision of our estimate of accrued royalties in the first quarter of 2025;
- a $350 million unfavorable impact of foreign exchange; and
- a $100 million unfavorable change in sales mix.

The increase in Cost of sales as a percentage of revenues in the first six months of 2026 was primarily due to the non-recurrence of a favorable revision of our estimate of accrued royalties in the first quarter of 2025, and an unfavorable impact of foreign exchange.

Certain of our vaccines, including Comirnaty, are subject to seasonality of demand, with a greater portion of revenues and related cost of sales anticipated in the fall and winter seasons.

Selling, Informational and Administrative Expenses

Selling, informational and administrative expenses were relatively flat in the second quarter of 2026, primarily reflecting:

- lower spending of $70 million in corporate enabling functions,

offset by:

- an increase of $40 million in implementation costs associated with our cost realignment program; and
- a $35 million unfavorable impact of foreign exchange.

Selling, informational and administrative expenses decreased $74 million in the first six months of 2026, primarily reflecting:

- lower spending of $130 million in corporate enabling functions; and
- a decrease of $100 million in marketing and promotional spend on various products from more targeted investments and ongoing productivity improvements,

partially offset by:

- a $90 million unfavorable impact of foreign exchange; and
- an increase of $70 million in implementation costs associated with our cost realignment program.

Research and Development Expenses

Research and development expenses increased $327 million in the second quarter and $614 million in the first six months of 2026, driven primarily by an increase in spending of $240 million and $420 million, respectively, in certain oncology and obesity product candidates, which was anticipated.

Acquired In-Process Research and Development Expenses

Acquired in-process research and development expenses increased $14 million in the second quarter and $142 million in the first six months of 2026, reflecting upfront and milestone payments on certain in-licensing agreements.

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

Realigning Our Cost Base Program––In the third quarter of 2026, we announced $1.0 billion of additional anticipated net cost savings associated with this program driven by further productivity enhancements from technology and simplification efforts across our commercial, R&D and enabling functions. These additional net savings are expected to further reduce costs in SI&A and be realized from 2027 through 2029. We previously announced that this program remains on track to deliver anticipated net cost savings of approximately $5.7 billion through 2026 ($5.1 billion achieved through 2025, and the remaining anticipated savings of $600 million, which are expected to be achieved by the end of 2026). With the additional anticipated savings, we now expect total net cost savings of approximately $6.7 billion from the program through 2029.

In addition, we have also achieved cost savings of approximately $500 million from our pipeline focus and optimization initiatives including the expansion of our digital capabilities, with the savings expected to be reinvested in R&D programs by the end of 2026.

Manufacturing Optimization Program––In the third quarter of 2026, we announced the next phase of this program designed to reduce our cost of goods sold. This phase is focused on network structure changes, product portfolio enhancements and additional operational efficiencies, and is expected to deliver additional savings of approximately $1.5 billion through 2029, some of which is expected to begin being realized in 2027. We previously announced that we remain on track to deliver anticipated net cost savings from the first phase of this program of approximately $1.5 billion by the end of 2027 (with approximately $1.3 billion of these net cost savings expected to be realized by the end of 2026). With the additional anticipated savings, we now expect total net cost savings of approximately $3.0 billion from the program through 2029.

Certain qualifying costs for these programs in all periods since inception were recorded and reflected as Certain Significant Items and excluded from our non-GAAP measure of Adjusted Income. See the [Non-GAAP Financial Measure: Adjusted Income](#ic3daa1857b29415b9ca41f62a8bb3d9e_196) section within MD&A.

For a description of our programs, as well as the anticipated and actual costs, see [Notes 3A](#ic3daa1857b29415b9ca41f62a8bb3d9e_55) and [3B](#ic3daa1857b29415b9ca41f62a8bb3d9e_55). The program savings discussed above may be rounded and represent approximations. In addition to these programs, we continuously monitor our operations for cost reduction and/or productivity opportunities, especially in light of patent-based and regulatory exclusivity expiries as well as the expiration of collaborative arrangements for various products. Long-term improvement in gross margin will remain a key focus for the Company over the next few years.

Metsera acquisition––In connection with our acquisition of Metsera, we are focusing our efforts on achieving an appropriate cost structure for the combined company. We expect to generate approximately $600 million of annual cost synergies, to be achieved by the end of 2026. The one-time costs to generate these synergies are expected to be approximately $700 million, incurred primarily from 2025 through 2027.

Other (Income)/Deductions—Net

The unfavorable period-over-period changes of $3.0 billion in the second quarter of 2026 and $2.9 billion for the first six months of 2026 were primarily driven by (i) intangible asset impairment charges, (ii) charges for certain legal matters, and (iii) increases in fair value of our contingent consideration liabilities, partially offset by (iv) a net gain in 2026 from the sale of our previous investment in ViiV. See [Notes 4](#ic3daa1857b29415b9ca41f62a8bb3d9e_61) and [7A](#ic3daa1857b29415b9ca41f62a8bb3d9e_76).

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

Changes in Tax Laws––Many countries outside the U.S. have enacted legislation for global minimum taxation resulting from the Organization for Economic Co-operation and Development’s (OECD) Base Erosion and Profit Shifting “Pillar 2” project. The provisions are generally effective for Pfizer since 2024, though significant details and guidance around the provisions are still pending. Income tax expense could be impacted as the legislation becomes effective in countries in which we do business, and such impact could be material to our results of operations. We continue to monitor pending OECD guidance and legislation enactment and implementation by individual countries.

On July 4, 2025, the OBBBA was enacted into law in the U.S. The OBBBA includes significant tax provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act and modifications to the U.S. international tax framework. Among the favorable business provisions are the permanent expensing for domestic R&D costs, permanent bonus depreciation, full expensing of qualified production property, and the reduction of the tax rate applicable to foreign earnings as GILTI (now NCTI) effective in fiscal years 2026 and thereafter from 13.125% to 12.6%. The legislation includes various effective dates, with certain provisions effective in 2025 and the rest in 2026. We expect further guidance may be issued by the U.S. government with respect to certain OBBBA tax provisions.

See the Provision/(Benefit) for Taxes on Income section within MD&A of our 2025 Form 10-K for more information.

As discussed in our 2025 Form 10-K, in September 2024, Pfizer announced a voluntary withdrawal of all lots of Oxbryta (voxelotor) for the treatment of SCD in all markets where it was approved. Pfizer also discontinued all active voxelotor clinical

trials and expanded access programs worldwide. Pfizer’s decision was based on the totality of the clinical trial and registry data available at the time.

Following comprehensive review and analysis of the totality of the data, Pfizer submitted updated analyses to the EMA, FDA and other regulators. In the EU, the EMA’s referral procedure concluded in October 2025, with the EMA adopting a negative opinion on benefit-risk for Oxbryta for the treatment of hemolytic anemia due to SCD, recommending that the marketing authorization for the product remain suspended. In July 2026, Pfizer engaged with the FDA to discuss the FDA’s assessment of the data and it was determined that there is no viable pathway for returning Oxbryta to market in the U.S. Consistent with the FDA’s recommendation, on July 31, 2026, Pfizer notified the FDA that it is voluntarily withdrawing the NDAs for Oxbryta.

In December 2024, the FDA issued a partial clinical hold for osivelotor, which prohibited Pfizer from enrolling new participants into osivelotor clinical studies. The FDA has since permitted initiation of osivelotor studies and confirmed enrollment may proceed outside of sub-Saharan Africa and for participants who have not relocated from sub-Saharan Africa within the last six months. Enrollment of new participants began in the first quarter of 2026.

In June 2026, we announced topline results from the Phase 3 SigVie-002 study evaluating sigvotatug vedotin, an investigational antibody-drug conjugate, in patients with previously treated, locally advanced, unresectable or metastatic non-squamous NSCLC. The study did not meet its primary endpoint of a statistically significant improvement in overall survival compared to docetaxel. The safety profile of sigvotatug vedotin was manageable and consistent with prior studies.

Adjusted income is an alternative measure of performance used by management to evaluate our overall performance as a supplement to our GAAP Reported 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 Relevance of Metrics to Our Business Performance
- Adjusted income Net income attributable to Pfizer Inc. common shareholders(a) before the impact of amortization of intangible assets, certain acquisition-related items, discontinued operations and certain significant items
- Provides investors useful information to:
  - evaluate the normal recurring operational activities, and their components, on a comparable year-over-year basis
  - assist in modeling expected future performance on a normalized basis
- Provides investors insight into the way we manage our budgeting and forecasting, how we evaluate and manage our recurring operations and how we reward and compensate our senior management(b)
- Adjusted cost of sales, Adjusted selling, informational and administrative expenses, Adjusted research and development expenses and Adjusted other (income)/deductions––net Cost of sales, Selling, informational and administrative expenses, Research and development expenses and Other (income)/deductions––net(a), each before the impact of amortization of intangible assets, certain 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 amortization of intangible assets, certain 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 versus three budgeted financial metrics, as well as performance against certain of our non-financial pipeline metrics, and may be further modified by our Compensation Committee’s assessment of other factors. One of the three financial metrics is Adjusted income (as defined for annual incentive compensation purposes), which accounts for 40% of the bonus pool funding tied to financial performance. Any expenses for acquired IPR&D are included in our non-GAAP Adjusted results but we exclude certain of these expenses for our financial results for annual incentive compensation purposes. Additionally, the payout for performance share awards is determined in part by Adjusted diluted EPS, which is derived from Adjusted income.

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 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 most 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.

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.

Adjusted Income and Adjusted Diluted EPS

Amortization of Intangible Assets—Adjusted income excludes all amortization of intangible assets.

Acquisition-Related Items—Adjusted income excludes certain acquisition-related items, which are composed 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. Acquisition-related items may include purchase accounting impacts such as the incremental charge to cost of sales from the sale of acquired inventory that was written up to fair value, depreciation related to the increase/decrease in fair value of acquired fixed assets, amortization related to the increase in fair value of acquired debt, and the fair value changes for contingent consideration.

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 product portfolio 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 programs are specific to an event or goal with a defined term, we may have subsequent programs based on reorganizations of the business, cost productivity or in response to generic or biosimilar entry 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, or legal matters generally related to divested products or businesses. Gains and losses on equity securities and pension and postretirement actuarial remeasurement gains and losses have a very high degree of inherent market volatility, which we do not control and cannot predict with any level of certainty, and we do not believe including these gains and losses assists investors in understanding our business or is reflective of our core operations and business. 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. See the Reconciliations of GAAP Reported to Non-GAAP Adjusted information—Certain Line Items below for a non-inclusive list of certain significant items and the Non-GAAP Financial Measure: Adjusted Income section within MD&A of our 2025 Form 10-K.

### ANALYSIS OF THE CONDENSED CONSOLIDATED STATEMENTS OF CASH FLOWS

| (MILLIONS) | Six Months Ended / June 28,2026 | Six Months Ended / June 29,2025 | Drivers of change |
| --- | --- | --- | --- |
| Cash provided by/(used in): |  |  |  |
| Operating activities | $3,450 | $1,753 | The change was driven mainly by the timing of receipts and payments in the ordinary course of business and a change in net income adjusted for non-cash items, including the impact of intangible asset impairments, partially offset by a net gain on the sale of our investment in ViiV. |
| Investing activities | $2,891 | $7,225 | The change was driven mainly by non-recurrence of $6.3 billion proceeds from the sale of the remaining portion of our previous investment in Haleon, partially offset by $1.9 billion proceeds from the sale of our investment in ViiV. |
| Financing activities | $(6,519) | $(8,423) | The change was driven mainly by a $3.0 billion decrease in net repayments of short-term borrowings and a $2.5 billion decrease in repayments of long-term debt, partially offset by non-recurrence of a $3.7 billion long term debt issuance. |

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

We believe that with our ongoing operating cash flows, together with our financial assets, access to capital markets, revolving credit agreement, and available lines of credit, we have and will maintain the ability to meet our liquidity needs to support ongoing operations, our capital allocation objectives, and our contractual and other obligations for the foreseeable future. For information about the sources and uses of our funds and capital resources, as well as our operating cash flows, see our [Condensed Consolidated Statements of Cash Flows](#ic3daa1857b29415b9ca41f62a8bb3d9e_37), [Condensed Consolidated Balance Sheets](#ic3daa1857b29415b9ca41f62a8bb3d9e_31), [Condensed Consolidated Statements of Equity](#ic3daa1857b29415b9ca41f62a8bb3d9e_34), and the [Analysis of the Condensed Consolidated Statements of Cash Flows](#ic3daa1857b29415b9ca41f62a8bb3d9e_205) section within MD&A. For information on our money market funds, available-for sale-debt securities and long-term debt, see [Note 7](#ic3daa1857b29415b9ca41f62a8bb3d9e_76).

For information about our diverse sources of funds, off-balance sheet arrangements, contractual and other obligations, global economic conditions and market risk, see the Analysis of Financial Condition, Liquidity, Capital Resources and Market Risk section within MD&A of our 2025 Form 10-K. For more information on guarantees and indemnifications, see [Note 12B](#ic3daa1857b29415b9ca41f62a8bb3d9e_127).

Credit Ratings––The cost and availability of financing are influenced by credit ratings, and an increase or decrease in our credit rating could have a beneficial or adverse effect on financing. Our long-term debt is rated high-quality by both S&P and Moody’s.

As of the date of the filing of this Form 10-Q, the following ratings have been assigned to our commercial paper and senior unsecured long-term debt:

NAME OF RATING AGENCY Pfizer Short-Term Rating Pfizer Long-Term Rating Outlook/Watch

Moody’s P-1 A2 Stable Outlook

S&P A-1 A Stable Outlook

These ratings are not recommendations to buy, sell or hold securities and the ratings are subject to revision or withdrawal at any time by the rating organizations. Each rating should be evaluated independently of any other rating.

Debt Capacity––Lines of Credit––As of the date of the filing of this Form 10-Q, we had access to a $7.0 billion committed revolving credit facility maturing in October 2030, which may be used for general corporate purposes including to support our global commercial paper borrowings. In addition to the revolving credit facility, our lenders have provided us an additional $226 million in lines of credit, essentially all expiring within one year. Essentially all lines of credit were unused as of the date of the filing of this Form 10-Q.

Capital Allocation Framework––Our capital allocation framework is designed to enhance long-term shareholder value and is based on three core pillars: reinvesting in the business, maintaining and, over the long term, growing our dividend, and in the future, the potential to make share repurchases after de-levering our balance sheet. Given the anticipated unfavorable impact from patent-based or regulatory exclusivity expiries over the next few years, we expect leverage to remain around current levels, or modestly higher, through this transition period. Over time, we expect to continue to de-lever in a prudent manner in order to maintain a balanced capital allocation strategy.

Dividends––In April 2026, our BOD declared a dividend of $0.43 per share, paid on June 12, 2026, to shareholders of record at the close of business on May 8, 2026. In June 2026, our BOD declared a dividend of $0.43 per share, payable on September 1, 2026, to shareholders of record at the close of business on July 24, 2026.

Common Stock Purchases—As of June 28, 2026, our remaining share-purchase authorization was $3.3 billion, with no repurchases in first six months of 2026. See Note 12 in our 2025 Form 10-K for more information on our publicly announced share-purchase plan.

Sale of Investment—On March 31, 2026, which fell in our second fiscal quarter of 2026, Pfizer completed the exit of its 11.7% investment in ViiV and received $1.875 billion in cash proceeds. See [Note](#ic3daa1857b29415b9ca41f62a8bb3d9e_49)[s](#ic3daa1857b29415b9ca41f62a8bb3d9e_49)[2](#ic3daa1857b29415b9ca41f62a8bb3d9e_49) and [4](#ic3daa1857b29415b9ca41f62a8bb3d9e_61).

NEW ACCOUNTING STANDARDS

Recently Issued Accounting Standards, Not Adopted as of June 28, 2026

Standard/Description Effective Date Effect on the    Financial Statements

In November 2024, the FASB issued final guidance which requires disaggregated disclosures of certain categories of expenses that are included in expense line items on the face of the income statement. The disclosures are required on an annual and interim basis. The guidance also requires the total amount of selling expenses to be disclosed and, on an annual basis, the definition of selling expenses. The guidance may be applied on a prospective or a retrospective basis. 2027 for annual reports and 2028 for interim reports. Early adoption is permitted. This new guidance will result in increased disclosures in the notes to our financial statements.

In September 2025, the FASB issued final guidance to modernize the accounting for internal use software costs. The guidance requires entities to start capitalizing eligible costs when (1) management has authorized and committed to funding the software project, and (2) it is probable that the project will be completed and the software will be used to perform the function intended. The guidance can be applied on a prospective basis, a modified basis for in-process projects, or a retrospective basis. January 1, 2028, with early adoption permitted. We are assessing the impact but currently do not expect this new guidance to have a material impact on our consolidated financial statements.

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 2025 Form 10-K and within 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, in the Item 1A. Risk Factors section in our 2025 Form 10-K or within MD&A, 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:

Risks Related to Our Business, Industry and Operations, and Business Development

- the outcome of R&D activities, including the ability to meet anticipated pre-clinical or clinical endpoints, commencement and/or completion dates for our pre-clinical or clinical trials, regulatory submission dates, and/or regulatory approval and/or

ITEM 4. CONTROLS AND PROCEDURES

As of the end of the period covered by this Form 10-Q, we carried out an evaluation, under the supervision and with the participation of our management, including 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).
