2025 FINANCIAL GUIDANCE⁽¹⁾

Reaffirms full-year 2025 Revenue guidance of $61.0 to $64.0 billion.
Raises and narrows Adjusted⁽²⁾ diluted EPS guidance⁽¹⁾ to a range of $3.00 to $3.15 from $2.90 to $3.10 previously.
The updated 2025 Adjusted⁽²⁾ diluted EPS guidance takes into consideration our solid year-to-date performance, continued confidence in our business, progress with ongoing cost improvement initiatives, and improvement in our effective tax rate.
- Includes a one-time $1.35 billion Acquired In-Process R&D charge related to the in-licensing agreement with 3SBio, Inc. recorded in the third quarter of 2025 with an unfavorable impact of approximately $0.20.
The company's guidance absorbs the impact of the currently imposed tariffs from China, Canada, and Mexico.

Revenues	$61.0 to $64.0 billion
Adjusted⁽²⁾ SI&A Expenses	$13.1 to $14.1 billion
Adjusted⁽²⁾ R&D Expenses	$10.0 to $11.0 billion
Adjusted⁽²⁾ R&D Expenses	(previously $10.4 to $11.4 billion)
Effective Tax Rate on Adjusted⁽²⁾ Income	Approximately 11.0%
Effective Tax Rate on Adjusted⁽²⁾ Income	(previously approximately 13.0%)
Adjusted⁽²⁾ Diluted EPS	$3.00 to $3.15
Adjusted⁽²⁾ Diluted EPS	(previously $2.90 to $3.10)

CAPITAL ALLOCATION

During the first nine months of 2025, Pfizer deployed its capital in a variety of ways, which primarily included:

Reinvesting capital into initiatives intended to enhance the future growth prospects of the company, including:
- $7.2 billion invested in internal research and development projects, and
- Approximately $1.6 billion invested in business development transactions, primarily reflecting the 3SBio in-licensing deal.
Returning capital directly to shareholders through $7.3 billion of cash dividends, or $1.29 per share of common stock.

No share repurchases have been completed to date in 2025. As of November 4, 2025, Pfizer's remaining share repurchase authorization is $3.3 billion. Current financial guidance does not anticipate any share repurchases in 2025. The company expects to continue to de-lever in a prudent manner in order to maintain a balanced capital allocation strategy. This includes maintaining the flexibility to deploy capital towards potential value-creating business development transactions and the potential to return capital to shareholders through share repurchases. Diluted weighted-average shares outstanding of 5,714 million and 5,705 million were used to calculate Reported⁽³⁾ and Adjusted⁽²⁾ diluted EPS for third-quarter 2025 and 2024, respectively.

QUARTERLY FINANCIAL HIGHLIGHTS (Third-Quarter 2025 vs. Third-Quarter 2024)

Third-quarter 2025 revenues totaled $16.7 billion, a decrease of $1.0 billion, or 6%, compared to the prior-year quarter, reflecting an operational decrease of $1.3 billion, or 7%, and a favorable impact of foreign exchange of $203 million. The operational decrease was primarily driven by a year-over-year decline in COVID-19 product revenues largely due to lower infection rates impacting Paxlovid demand as well as a narrower vaccine recommendation for COVID-19 in the U.S. that reduced the eligible population for Comirnaty.

Third-quarter 2025 operational revenue reflected higher revenues primarily for:

Eliquis globally, up 22% operationally, driven primarily by higher demand globally and favorable net price in the U.S. as a result of the expected favorable year-over-year impact of the elimination of the coverage gap as part of the IRA Medicare Part D Redesign, partially offset by generic entry and price erosion in certain international markets;
Vyndaqel family (Vyndaqel, Vyndamax, Vynmac) globally, up 7% operationally, driven largely by strong demand with continuing uptake in patient diagnosis primarily in the U.S. and certain international developed markets, as well as improved patient affordability in the U.S.; partially offset by lower net price in the U.S. mostly due to the impact of higher manufacturer discounts resulting from the IRA Medicare Part D Redesign, as well as new payer contracts; and
Nurtec ODT/Vydura globally, up 22% operationally, driven primarily by strong demand in the U.S. and recent launches in certain international markets, partially offset by lower net price in the U.S. mainly due to unfavorable changes in channel mix;

more than offset primarily by lower revenues for:

Paxlovid, down 55% operationally, driven primarily by lower COVID-19 infections across U.S. and international markets and lower international government purchases, as well as the non-recurrence of a $442 million favorable U.S. government stockpile purchase in the third quarter of 2024; partially offset by favorable adjustments of rebate accruals related to prior periods, as well as higher net price in the U.S. following transition from the U.S. government agreement; and
Comirnaty, down 20% operationally, mainly due to a narrower recommendation for vaccination in the U.S. as well as delayed approval of the new variant vaccine; partially offset by a lower returns provision and higher market share in the U.S., as well as higher contractual deliveries in certain international markets.

* Indicates calculation not meaningful or results are greater than 100%.

Third-quarter 2025 Cost of Sales⁽³⁾ as a percentage of revenues decreased by 4.7 percentage points compared to the prior-year quarter, primarily driven by (i) a favorable revision of our estimate of accrued royalties, (ii) a favorable change in sales mix driven by lower sales of Comirnaty and Paxlovid, including the non-recurrence of a charge recorded in the third quarter of 2024 that was included in the 50% gross profit split with BioNTech and applicable royalty expenses, and (iii) lower amortization from the step-up of acquired inventory; partially offset by (iv) an unfavorable impact of foreign exchange.

Third-quarter 2025 SI&A Expenses⁽³⁾ decreased 3% operationally compared with the prior-year quarter, primarily reflecting focused investments and ongoing productivity improvements that drove a decrease in marketing and promotional spend for various products and lower spending in corporate enabling functions, partially offset by higher healthcare reform fees in the current period primarily due to a favorable adjustment recorded in the third quarter of 2024.

Third-quarter 2025 R&D Expenses⁽³⁾ decreased 2% operationally compared with the prior-year quarter, driven primarily by a net decrease in spending due to pipeline focus and optimization including the expansion of our digital capabilities, as well as lower compensation-related expenses.

Third-quarter 2025 Acquired In-Process R&D Expenses⁽³⁾ increased $1.4 billion compared to the prior-year quarter, driven primarily by a $1.35 billion charge related to an in-licensing agreement with 3SBio, Inc.

The unfavorable period-over-period change in Other (income)/deductions—net⁽³⁾ of $275 million for the third quarter of 2025, compared with the prior-year quarter, was driven primarily by (i) an intangible asset impairment charge in the third quarter of 2025, (ii) lower net gains on equity securities, (iii) the non-recurrence of equity method income in the third quarter of 2024 from our previous investment in Haleon plc and (iv) higher charges for certain legal matters; partially offset by (v) a non-recurrence of a charge in the third quarter of 2024 related to the expected sale of one of our facilities resulting from the discontinuation of our Duchenne muscular dystrophy program and (vi) lower net interest expense.

Pfizer's effective tax rate on Reported⁽³⁾ income for the third quarter of 2025 decreased compared to the prior-year quarter primarily due to a favorable change in the jurisdictional mix of earnings, the remeasurement of deferred tax liabilities due to the enactment of the One Big Beautiful Bill Act on July 4, 2025, and tax benefits related to global income tax resolutions in multiple tax jurisdictions spanning multiple tax years.

RECENT NOTABLE DEVELOPMENTS (Since August 5, 2025)

Product Developments

Product/Project	Milestone	Recent Development	Link
Braftovi (encorafenib) + Mektovi (binimetinib)	*Phase 2* *Four-Year Data*	October 2025. Announced updated follow-up results from the single-arm Phase 2 PHAROS trial evaluating Braftovi + Mektovi for the treatment of adults with metastatic non-small cell lung cancer (mNSCLC) with a BRAF V600E mutation. In treatment-naïve patients, the median overall survival (OS) was 47.6 months (95% confidence interval [CI], 31.3, not estimable) after a median follow-up of 52.3 months. In previously treated patients, the median OS was 22.7 months (95% CI, 14.1, 32.6), after a median follow-up of 48.2 months. The four-year OS rates were 49% (95% CI, 35, 62) and 31% (95% CI, 16, 47) for treatment-naïve and previously treated patients, respectively. At the time of this analysis, the safety profile of Braftovi + Mektovi was consistent with previous findings.	Full Release
Comirnaty (COVID-19 Vaccine, mRNA)	*Phase 3 Results*	September 2025. Pfizer and BioNTech announced positive topline results from an ongoing Phase 3 clinical trial cohort evaluating the safety, tolerability, and immunogenicity of a 30-µg dose of the LP.8.1-adapted monovalent Comirnaty 2025-2026 Formula in adults aged 65 and older and in adults aged 18 through 64 with at least one underlying risk condition for severe COVID-19. The preliminary data show a robust increase in neutralizing antibodies targeting the LP.8.1 sublineage of SARS-CoV-2 following vaccination. These clinical findings reinforce pre-clinical data that supported the U.S. Food and Drug Administration (FDA) approval of the LP.8.1-adapted COVID-19 vaccine, which demonstrated improved immune responses against multiple circulating SARS-CoV-2 sublineages.	Full Release
	*ACIP Vote*	September 2025. The U.S. Centers for Disease Control and Prevention's (CDC) Advisory Committee on Immunization Practices (ACIP) unanimously recommended COVID-19 vaccination for individuals six months and older based on shared clinical decision-making. This recommendation was subsequently adopted by the Director of the CDC and the U.S. Department of Health and Human Services.	Full Release
	*Regulatory*	August 2025. Pfizer and BioNTech announced the FDA approved the supplemental Biologics License Application (sBLA) for the companies' LP.8.1-adapted monovalent COVID-19 vaccine for use in adults ages 65 years and older, as well as in individuals ages 5 through 64 years with at least one underlying condition that puts them at high risk for severe outcomes from COVID-19.	Full Release
Padcev (enfortumab vedotin)	*Phase 3 Results*	October 2025. Pfizer and Astellas Pharma Inc. announced positive results from the Phase 3 EV-303 clinical trial (also known as KEYNOTE-905) evaluating Padcev in combination with pembrolizumab as neoadjuvant and adjuvant treatment (before and after surgery) versus surgery alone, the current standard of care, in patients with muscle-invasive bladder cancer (MIBC) who are not eligible for or declined cisplatin-based chemotherapy. At the first interim efficacy analysis, results from the primary endpoint of event-free survival (EFS) showed a 60% reduction in the risk of tumor recurrence, progression or death for patients treated with neoadjuvant and adjuvant Padcev plus pembrolizumab as compared to surgery alone (Hazard Ratio (HR) of 0.40; 95% CI, 0.28-0.57; p<0.0001). The estimated median EFS has not yet been reached for the combination arm versus 15.7 months for the surgery alone arm. An estimated 74.7% of patients treated with the combination were event free at two years, relative to 39.4% of patients who received surgery only. Results from the key secondary endpoint of OS showed a 50% reduction in the risk of death for neoadjuvant and adjuvant Padcev plus pembrolizumab as compared to surgery alone (HR of 0.50; 95% CI, 0.33-0.74; p<0.0002). The estimated median OS has not yet been reached for the combination arm versus 41.7 months for the surgery arm. An estimated 79.7% of patients were alive at two years relative to 63.1% of patients who received surgery only. The safety results in EV-303 were consistent with those previously reported for this combination.	Full Release
Tukysa (tucatinib)	*Phase 3 Results*	October 2025. Announced positive topline results from the Phase 3 HER2CLIMB-05 trial of first-line combination therapy with the tyrosine kinase inhibitor Tukysa in patients with human epidermal growth factor receptor 2-positive (HER2+) metastatic breast cancer (MBC). HER2CLIMB-05 is evaluating Tukysa versus placebo, both in combination with first-line standard-of-care maintenance therapy (trastuzumab plus pertuzumab) following chemotherapy-based induction. The trial met its primary endpoint, demonstrating a statistically significant and clinically meaningful improvement in progression-free survival (PFS) by investigator assessment in the Tukysa arm versus the placebo arm. Treatment with Tukysa in combination with trastuzumab and pertuzumab was tolerable, with a safety profile generally consistent with the established safety profiles of each individual therapy.	Full Release
Xtandi (enzalutamide)	*Phase 3 Results*	October 2025. Pfizer and Astellas Pharma Inc. announced final OS results from the Phase 3 EMBARK study evaluating Xtandi, in combination with leuprolide and as monotherapy, in men with non-metastatic hormone-sensitive prostate cancer (nmHSPC; also known as nonmetastatic castration-sensitive prostate cancer or nmCSPC) with biochemical recurrence (BCR) at high risk for metastasis. For the key secondary endpoint of OS, Xtandi plus leuprolide reduced the risk of death by 40.3% compared to leuprolide alone (Hazard Ratio [HR]: 0.597; 95% CI, 0.444-0.804; p=0.0006), making this the first and only androgen receptor inhibitor-based regimen to demonstrate an OS benefit in nmHSPC with high-risk BCR. The 8-year overall survival was 78.9% (95% CI, 73.9% to 83.1%) among patients receiving Xtandi plus leuprolide and 69.5% (95% CI, 64.0% to 74.3%) among patients taking leuprolide alone. A numerical improvement in OS with Xtandi as monotherapy compared to leuprolide alone (HR: 0.83 [95% CI, 0.63-1.095]; p=0.1867) did not reach statistical significance. The safety profile of Xtandi was consistent with that observed at the primary EMBARK analysis, and no new safety signals were identified.	Full Release

inclacumab	*Phase 3 Results*	August 2025. Announced results from the Phase 3 THRIVE-131 study evaluating inclacumab, an investigational P-selectin inhibitor, in patients 16 years of age and older with sickle cell disease (SCD). The study did not meet its primary endpoint of significant reduction in the rate of vaso-occlusive crises (VOCs) in participants receiving inclacumab versus placebo every 12 weeks over 48 weeks. Inclacumab was generally well tolerated in THRIVE-131. The most commonly reported treatment-emergent adverse events in either group were anemia, arthralgia, back pain, headache, malaria, sickle cell anemia with crisis, and upper respiratory tract infection.

Agreement with U.S. Government	September 2025. Announced a historic agreement with the Trump Administration in which Pfizer has voluntarily agreed to implement measures designed to ensure Americans receive comparable drug prices to those available in other developed countries and pricing newly launched medicines at parity with other key developed markets. Under the agreement, Pfizer will also participate in a direct purchasing platform, TrumpRx.gov, that will allow American patients to purchase medicines from Pfizer at a significant discount. The large majority of the Company's primary care treatments and some select specialty brands will be offered at savings that will range as high as 85% and on average 50%. The agreement provides a three-year grace period during which time Pfizer products under a Section 232 investigation will not face tariffs, provided the company further invests in manufacturing in the United States.

Announced Pfizer entered into a definitive agreement to acquire Metsera, a clinical-stage biopharmaceutical company accelerating the next generation of medicines for obesity and cardiometabolic diseases, for $47.50 in cash per Metsera share at closing, representing an enterprise value of approximately $4.9 billion. Additionally, the agreement includes a non-transferable contingent value right (CVR) entitling holders to potential additional payments of up to $22.50 per share tied to three specific milestones: $5 per share following the Phase 3 clinical trial start of Metsera's injectable GLP-1 receptor agonist (MET-097i) + amylin analog (MET-233i) combination, $7 per share following FDA approval of the monthly GLP-1 receptor agonist MET-097i monotherapy, and $10.50 per share following FDA approval of the monthly MET-097i + MET-233i combination, if achieved. Pfizer expects to finance the transaction through a combination of available cash and new debt. The transaction is subject to the satisfaction of customary closing conditions, including receipt of approval by Metsera's shareholders.	Full Release
	October 2025. Announced the U.S. Federal Trade Commission granted early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, with respect to Pfizer's pending acquisition of Metsera. As such, all required regulatory approvals in respect of Pfizer's acquisition of Metsera have been obtained.	Full Release
	October-November 2025. Announced that Pfizer has filed lawsuits against Metsera, Novo Nordisk A/S and several related parties and individuals in the Delaware Court of Chancery and the U.S. District Court of the District of Delaware for claims relating to a competing proposal to acquire Metsera made by Novo Nordisk on October 25, including claims for breach of contract, breach of fiduciary duty, and tortious interference in contract arising from Metsera's breach of its obligations under the merger agreement between Pfizer and Metsera, as well as various antitrust-related claims. Pfizer is requesting the Delaware Court of Chancery issue a temporary restraining order to block Metsera from terminating the merger agreement and seeks all appropriate remedies to ensure the terms of the merger agreement are fully enforced. The company is confident in the merits of these cases.	Full Release & Full Release

For additional details, see the financial schedules and product revenue tables within the press release located at the hyperlink above, and the attached disclosure notice.

(1)		Pfizer does not provide guidance for U.S. generally accepted accounting principles (GAAP) Reported financial measures (other than revenues) or a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP Reported financial measures on a forward-looking basis because it is unable to predict with reasonable certainty the ultimate outcome of unusual gains and losses, certain acquisition-related expenses, gains and losses from equity securities, actuarial gains and losses from pension and postretirement plan remeasurements, potential future asset impairments and pending litigation without unreasonable effort. These items are uncertain, depend on various factors, and could have a material impact on GAAP Reported results for the guidance period.

		Financial guidance for full-year 2025 reflects the following:

		Does not assume the completion of any business development transactions not completed as of November 4, 2025. An anticipated unfavorable revenue impact of approximately $0.4 billion due to recent and expected generic and biosimilar competition for certain products that have recently lost patent or regulatory protection or that are anticipated to lose patent or regulatory protection. Exchange rates assumed are a blend of actual rates in effect through third-quarter 2025 and mid-October 2025 rates for the remainder of the year. Guidance for Adjusted⁽²⁾ diluted EPS assumes diluted weighted-average shares outstanding of approximately 5.71 billion shares, and assumes no share repurchases in 2025. The company's guidance absorbs the impact of the currently imposed tariffs from China, Canada, and Mexico.
(2)		Adjusted income and Adjusted diluted earnings per share (EPS) are defined as U.S. GAAP net income attributable to Pfizer Inc. common shareholders and U.S. GAAP diluted EPS attributable to Pfizer Inc. common shareholders before the impact of amortization of intangible assets, certain acquisition-related items, discontinued operations and certain significant items. See the reconciliations of certain GAAP Reported to Non-GAAP Adjusted information for the third quarter and the first nine months of 2025 and 2024 in the press release at the hyperlink above. Adjusted income and its components and Adjusted diluted EPS measures are not, and should not be viewed as, substitutes for U.S. GAAP net income and its components and diluted EPS⁽³⁾. See the Non-GAAP Financial Measure: Adjusted Income section of Management's Discussion and Analysis of Financial Condition and Results of Operations in Pfizer's 2024 Annual Report on Form 10-K and the accompanying Non-GAAP Financial Measure: Adjusted Income section of the press release located at the hyperlink above for a definition of each component of Adjusted income as well as other relevant information.

(3)		Revenues is defined as revenues in accordance with U.S. GAAP. Reported net income and its components are defined as net income attributable to Pfizer Inc. common shareholders and its components in accordance with U.S. GAAP. Reported diluted EPS is defined as diluted EPS attributable to Pfizer Inc. common shareholders in accordance with U.S. GAAP.

(4)		On track to deliver approximately $7.7 billion in anticipated overall savings (approximately $7.2 billion of net cost savings) from previously announced cost improvement initiatives:

		Approximately $4.5 billion of overall net cost savings from Pfizer's ongoing cost realignment program are expected to be achieved by the end of 2025. An additional approximately $1.2 billion of anticipated net cost savings, primarily in SI&A, is expected to be fully achieved by the end of 2027. The net cost savings are calculated versus the midpoint of Pfizer's 2023 SI&A and R&D expense guidance provided on August 1, 2023. On track to deliver anticipated R&D re-organization cost savings of approximately $500 million to be fully realized by the end of 2026, with savings to be reinvested in the pipeline. The first phase of the Manufacturing Optimization Program is on track to deliver approximately $1.5 billion in net cost savings by the end of 2027, contributing savings in third-quarter 2025.

(5)		References to operational variances in this press release pertain to period-over-period changes that exclude the impact of foreign exchange rates. Although foreign exchange rate changes are part of Pfizer's business, they are not within Pfizer's control and because they can mask positive or negative trends in the business, Pfizer believes presenting operational variances excluding these foreign exchange changes provides useful information to evaluate Pfizer's results.

(6)		Pfizer's fiscal year-end for international subsidiaries is November 30 while Pfizer's fiscal year-end for U.S. subsidiaries is December 31. Therefore, Pfizer's third quarter and first nine months for U.S. subsidiaries reflects the three and nine months ended on September 28, 2025 and September 29, 2024, while Pfizer's third quarter and first nine months for subsidiaries operating outside the U.S. reflects the three and nine months ended on August 24, 2025 and August 25, 2024.
