Pfizer Inc. (NYSE:PFE) today provided its full-year 2026 guidance ⁽²⁾ while revising its November 4, 2025 full-year 2025 Revenue guidance ⁽²⁾ and reaffirming all other components of full-year 2025 financial guidance ⁽²⁾ . The accompanying presentation can be found at www.pfizer.com/investors .

FULL-YEAR 2026 REVENUE GUIDANCE ⁽²⁾

Pfizer anticipates full-year 2026 revenues to be in the range of $59.5 to $62.5 billion, while full-year 2025 revenue guidance ⁽²⁾ is revised to approximately $62.0 billion from the range of $61.0 to $64.0 billion previously. Full-year 2026 revenue guidance ⁽²⁾ includes the expectation of revenues from our COVID-19 products being approximately $1.5 billion lower than what is expected in 2025 plus an expected year-over-year negative revenue impact of approximately $1.5 billion due to certain products experiencing loss of exclusivity (LOE) ⁽²⁾ . Pfizer expects full-year 2026 operational ⁽³⁾ revenue growth at the midpoint, excluding both COVID-19 and LOE products, to be approximately 4% year-over-year.

FULL-YEAR 2026 ADJUSTED ⁽¹⁾ SI&A and ADJUSTED ⁽¹⁾ R&D EXPENSES GUIDANCE ⁽²⁾

Pfizer anticipates full-year 2026 Adjusted ⁽¹⁾ SI&A expenses to be in the range of $12.5 to $13.5 billion, reflecting ongoing progress with our Cost Realignment Program. The company anticipates full-year 2026 Adjusted ⁽¹⁾ R&D expenses to be in the range of $10.5 to $11.5 billion, reflecting continued focus on prioritization in key therapeutic areas and maximizing the development of PF-08634404 (a PD-1 x VEGF bispecific antibody in-licensed from 3SBio) as well as multiple clinical programs from Metsera. Consequently, total 2026 Adjusted ⁽¹⁾ SI&A and R&D expenses are expected to be in the range of $23.0 to $25.0 billion.

FULL-YEAR 2026 ADJUSTED ⁽¹⁾ DILUTED EPS GUIDANCE ⁽²⁾

Pfizer anticipates full-year 2026 Adjusted ⁽¹⁾ diluted EPS to be in a range of $2.80 to $3.00. 2026 Adjusted ⁽¹⁾ diluted EPS guidance ⁽²⁾ primarily reflects our expected revenues, anticipated stable gross and operating margins vs full-year 2025 guidance ⁽²⁾ , and an anticipated higher tax rate on Adjusted ⁽¹⁾ income vs full-year 2025 guidance ⁽²⁾ .

A comparison of Pfizer's 2025 Financial Guidance ⁽²⁾ to its 2026 Financial Guidance ⁽²⁾ is presented below.

Financial guidance for Adjusted ⁽¹⁾ diluted EPS is calculated using approximately 5.71 billion weighted-average shares outstanding in 2025 and approximately 5.74 billion weighted-average shares outstanding in 2026, and assumes no share repurchases in 2025 or 2026.

CEO COMMENTARY

"2025 was a year of strong execution and strategic progress for Pfizer. We've strengthened our foundation, advanced our R&D pipeline and positioned our company for sustainable growth in the post-LOE period. As we move into 2026, we're focused on serving patients with innovative medicines and vaccines while creating long-term value for our shareholders."

• the outcome of research and development (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 launch dates; the possibility of unfavorable pre-clinical and clinical trial results, including the possibility of unfavorable new pre-clinical or clinical data and further analyses of existing pre-clinical or clinical data; risks associated with preliminary, early stage or interim data; the risk that pre-clinical and clinical trial data are subject to differing interpretations and assessments, including during the peer review/publication process, in the scientific community generally, and by regulatory authorities; whether and when additional data from our pipeline programs will be published in scientific journal publications and, if so, when and with what modifications and interpretations; and uncertainties regarding the future development of our product candidates, including whether or when our product candidates will advance to future studies or phases of development or whether or when regulatory applications may be filed for any of our product candidates, including as a result of clinical trial data or regulatory feedback that could impact the future development of our product candidates, including our vaccine candidates such as our next generation pneumococcal conjugate vaccine candidate;
• our ability to successfully address comments received from regulatory authorities such as the U.S. Food and Drug Administration or the European Medicines Agency, or obtain approval for new products and indications from regulators on a timely basis or at all;

• the success and impact of external business development activities, such as the November 2025 acquisition of Metsera, including the ability to identify and execute on potential business development opportunities; the ability to satisfy the conditions to closing of announced transactions in the anticipated time frame or at all, including the possibility that such transactions do not close; the ability to realize the anticipated benefits of any such transactions in the anticipated time frame or at all; the potential need for and impact of additional equity or debt financing to pursue these opportunities, which has in the past and could in the future result in increased leverage and/or a downgrade of our credit ratings and could limit our ability to obtain future financing; challenges integrating the businesses and operations; disruption to business or operations relationships; risks related to growing revenues for certain acquired or partnered products; significant transaction costs; and unknown liabilities;
• competition, including from new product entrants, in-line branded products, generic products, private label products, biosimilars and product candidates that treat or prevent diseases and conditions similar to those treated or intended to be prevented by our in-line products and product candidates;
