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 throughtwo operating segments, each led by a single manager: Biopharma and PC1. Biopharma is the only reportable segment. See Note 13A.

B. Revenues and Trade Accounts Receivable

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 ofthree specified milestones: $4.60 per share following the Phase 3 clinical trial start of Metsera’s injectable GLP-1 receptor antagonist MET-097i+amylin analog MET-233i combination, $6.40 per share following FDA approval of Metsera’s monthly MET-097i monotherapy and $9.65 per share following FDA approval of Metsera’s monthly MET-097i+MET-233i combination. The total fair value of the consideration transferred was $8.0 billion ($7.8 billion net of cash acquired), which includes the fair value of $632 million for the 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 ofidentifiable 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 4 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).

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 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.

C. Key Activities

(a)Primarily represents cost-reduction initiatives. Amounts associated with our Biopharma segment: (i) charges of $390 million for the three months ended June 28, 2026 (including charges of $417 million for our Realigning our Cost Base Program and credits of $29 million for our Manufacturing Optimization Program), (ii) charges of $421 million for the six months ended June 28, 2026 (including charges of $464 million for our Realigning our Cost Base Program and credits of $52 million for our Manufacturing Optimization Program), (iii) credits of $406 million for the three months ended June 29, 2025 (including credits of $408 million for our Manufacturing Optimization Program and $25 million for our Realigning our Cost Base Program) and (iv) charges of $211 million for the six months ended June 29, 2025 (including charges of $562 million for our Realigning our Cost Base Program and credits of $412 million for our Manufacturing Optimization Program). For 2025, Employee terminations included revisions of estimates of previously recorded accruals for severance benefits, driven in large part by higher-than-expected voluntary attrition.
