Pfizer Provides Full-Year 2025 Guidance and Reaffirms Full-Year 2024 Guidance

▪Full-Year 2025 Revenue Guidance(1) Range of $61.0 to $64.0 Billion

▪Full-Year 2025 Adjusted(2) Diluted EPS Guidance Range of $2.80 to $3.00

▪Expect Full-Year 2025 Adjusted(2) Diluted EPS Operational(3) Growth of 10% to 18% from the Midpoint of 2024 Guidance After Adjusting for 2024 Non-Recurring Items(4)

▪Achieved Goal of $4.0 Billion in Net Cost Savings Through 2024 and Anticipate an Additional $500 Million in Savings in 2025 from Ongoing Cost Realignment Program

▪First Phase of Manufacturing Optimization Program On Track to Deliver Initial Net Cost Savings in the Latter Part of 2025, Toward Goal of Improving Gross Margin Performance

NEW YORK, December 17, 2024 — Pfizer Inc. (NYSE:PFE) today provided its full-year 2025 guidance(1) and reaffirmed its October 29, 2024 full-year 2024 guidance(1). The accompanying presentation can be found at www.pfizer.com/investors.

Full-Year 2025 Revenue Guidance(1)

Pfizer anticipates full-year 2025 revenues to be in the range of $61.0 to $64.0 billion, which includes the expectation of revenues from our COVID-19 products in 2025 being largely consistent with 2024 after excluding approximately $1.2 billion of non-recurring revenue for Paxlovid in 2024. Pfizer expects full-year 2025 operational(3) revenue growth, year-over-year, in a range of approximately flat to 5% from the midpoint of 2024 baseline guidance(4), which excludes 2024 non-recurring items(4).

2025 Revenue guidance takes into consideration the anticipated net unfavorable impact to revenue of approximately $1 billion, year-over-year, related to the Inflation Reduction Act (IRA) Part D Redesign changes that take effect in 2025. The IRA makes significant changes to the Medicare Part D benefit design, which will impact Pfizer revenue in 2025, including: an expected favorable impact from the $2,000 annual out-of-pocket cap and new Prescription Payment Plan, more than offset by an expected unfavorable impact from the sunsetting of the Coverage Gap Discount Program and the addition of new manufacturer discounts in the initial and catastrophic coverage phases.

Full-Year 2025 Adjusted(2) SI&A and Adjusted(2) R&D Guidance(1)

Pfizer anticipates full-year 2025 Adjusted(2) SI&A expenses to be in the range of $13.3 to $14.3 billion and full-year 2025 Adjusted(2) R&D expenses to be in the range of $10.7 to $11.7 billion. Consequently, total 2025 Adjusted(2) SI&A and R&D expenses are expected to be in the range of $24.0 to $26.0 billion. This range reflects approximately $4.0 billion in net operating expense savings from our cost realignment program achieved through the end of 2024 and anticipates an additional $500 million of savings in 2025.

Full-Year 2025 Adjusted(2) Diluted EPS Guidance(1)

Pfizer anticipates full-year 2025 Adjusted(2) diluted EPS to be in a range of $2.80 to $3.00, reflecting expected operational(3) growth of 10% to 18%, year-over-year, from the midpoint of our 2024 baseline guidance(4), which excludes 2024 non-recurring items(4). 2025 Adjusted(2) diluted EPS guidance primarily reflects our expected revenues, anticipated operating margin improvement from continued cost management, and the non-recurrence of the following items that are expected to favorably impact 2024 Adjusted(2) diluted EPS by approximately $0.30:

•During 2024, Pfizer recognized Paxlovid revenue of $1.2 billion from two one-time items: $771 million from a U.S. Government revenue credit true-up and $442 million from the fulfillment of our obligated delivery of one million treatment courses to the U.S. Strategic National Stockpile;

•With the reduction of our Haleon ownership percentage in the fourth quarter of 2024, Haleon equity method income will no longer be included in Adjusted(2) earnings in 2025; and

•Our 2024 tax rate on adjusted income was favorably impacted by the timing of Pillar 2 and, to a lesser extent, audit settlements.

Executive Commentary

Dr. Albert Bourla, Pfizer Chairman and Chief Executive Officer, stated: “Pfizer is in a strong position to continue making a positive impact for patients and delivering on our financial commitments in 2025. Our team will build on a year of disciplined execution in 2024 and our product portfolio remains strong.

“We also expect to continue improving our operating margins with focused financial discipline. We’ve been successful in delivering on our goal of $4 billion in net operating expense savings through 2024 from our cost realignment program, with an additional $500 million still expected to come in 2025. Additionally, in support of our ongoing efforts to improve gross margin

performance, we will work to make additional progress with our Manufacturing Optimization Program in the coming year.

“As we look forward, we are confident in our future. With our clear strategic roadmap, a robust pipeline of potential innovative medicines and vaccines and a talented team laser-focused on execution, we believe we are on course to deliver significant shareholder value.”

Pfizer intends to provide additional commentary in an analyst webcast scheduled for 8:30 a.m. EST, Tuesday, December 17, 2024; details can be found at www.investors.pfizer.com.

(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 U.S. 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 December 16, 2024.

•Reflects an anticipated negative revenue impact of approximately $0.6 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 actual rates at mid-November 2024.

•Guidance for Adjusted(2) diluted EPS assumes diluted weighted-average shares outstanding of approximately 5.74 billion shares, and assumes no share repurchases in 2025.

Our reaffirmed financial guidance for full-year 2024 reflects assumptions that are consistent with those outlined in Note (1) within Pfizer’s Q3-24 Earnings Release.

(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. 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(6), have no standardized meaning prescribed by U.S. GAAP and may not be comparable to the calculation of similar measures of other companies. 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 2023 Annual Report on Form 10-K for a definition of each component of Adjusted income as well as other relevant information.

(3)References to operational variances in this press release pertain to period-over-period changes that exclude the impact of foreign exchange rates. Although 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.

(4)Pfizer reaffirms 2024 Guidance (last updated on October 29, 2024) as of the publication of this December 17, 2024 press release. Within this press release and other related materials, all references to Pfizer’s 2024 baseline guidance indicates our 2024 Guidance excluding 2024 non-recurring items. Our 2024 baseline Revenue guidance range excludes $1.2 billion in non-recurring 2024 Paxlovid revenues, and our baseline Adjusted(2) diluted EPS guidance range excludes an anticipated favorable impact in 2024 of approximately $0.30 from non-recurring items, as outlined under the ‘Full-Year 2025 Adjusted(2) Diluted EPS Guidance’ section of this press release.

(5)Expected operational growth percentage, on a year-over-year basis, represents lower and upper end of the 2025 guidance range versus the midpoint of the 2024 baseline guidance range.

(6)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.
