The fourth-quarter 2024 earnings presentation and accompanying prepared remarks from management as well as the quarterly update to Pfizer’s R&D pipeline can be found at www.pfizer.com.

EXECUTIVE COMMENTARY

Dr. Albert Bourla, Chairman and Chief Executive Officer, stated: “2024 was a strong year of execution and performance for Pfizer in which we met or exceeded our strategic and financial commitments, strengthened our company and, most importantly, reached millions of patients with our medicines and vaccines. We made great progress with commercial execution and achieved growth across our product portfolio for full-year 2024, including $3.4 billion in revenue from our legacy Seagen portfolio, as well as robust growth from the Vyndaqel family, Eliquis, Xtandi, Nurtec, and several other products across all categories.

“I’m excited for what’s ahead and confident that we will enhance shareholder value as we sharpen our focus to improve the productivity of our R&D pipeline and advance the clear strategic priorities guiding our company in 2025.”

David Denton, Chief Financial Officer and Executive Vice President, stated: “We are pleased with the 12% operational revenue growth of Pfizer’s non-COVID products in full-year 2024, demonstrating our continued focus on commercial execution. We successfully delivered on our $4 billion net cost savings target from our ongoing

- 1 -

cost realignment program, and, as captured in our 2025 financial guidance, we have increased our overall savings target to approximately $4.5 billion by the end of this year. In addition, we remain on track to deliver $1.5 billion of net cost savings from the first phase of our Manufacturing Optimization Program by the end of 2027, with initial savings expected in the latter part of 2025. We remain confident in our ability to return to pre-pandemic operating margins in the coming years.”

OVERALL RESULTS

In the first quarter of 2024, Pfizer reclassified royalty income (substantially all of which is related to our Biopharma segment) from Other (income)/deductions––net to revenues and began presenting Royalty revenues as a separate line item within Total revenues in our consolidated statements of operations. Prior-period amounts have been recast to conform to the current presentation.

Some amounts in this press release may not add due to rounding. All percentages have been calculated using unrounded amounts. References to operational variances pertain to period-over-period changes that exclude the impact of foreign exchange rates(6).

Results for fourth quarter and full year 2024 and 2023(7) are summarized below.

2025 FINANCIAL GUIDANCE(5)

Pfizer’s 2025 financial guidance(5) is presented below.



Revenues						$61.0 to $64.0 billion


Adjusted(3) SI&A Expenses						$13.3 to $14.3 billion
Adjusted(3) R&D Expenses						$10.7 to $11.7 billion
Effective Tax Rate on Adjusted(3) Income						Approximately 15.0%


Adjusted(3) Diluted EPS						$2.80 to $3.00

CAPITAL ALLOCATION

In 2024, Pfizer deployed its capital in a variety of ways, which primarily included:

▪Reinvested capital into initiatives intended to enhance the future growth prospects of the company, including:

•$10.8 billion invested in internal research and development projects, and

•Approximately $300 million invested in business development transactions.

▪Returned capital directly to shareholders through $9.5 billion of cash dividends, or $1.68 per share of common stock.

No share repurchases were completed in 2024. As of February 4, 2025, Pfizer’s remaining share repurchase authorization is $3.3 billion. Current financial guidance does not anticipate any share repurchases in 2025. Pfizer expects to sufficiently de-lever its balance sheet by the end of 2025 in order to return to a more balanced capital allocation strategy. This includes the flexibility to deploy capital towards potential value-creating business development transactions and the potential to return capital to shareholders through share repurchases.

For the fourth quarter of 2024, diluted weighted-average shares outstanding of 5,703 million were used to calculate Reported(2) and Adjusted(3) diluted EPS. For the fourth quarter of 2023, basic weighted-average shares outstanding of 5,647 million were used to calculate Reported(2) LPS and diluted weighted-average shares outstanding of 5,692 million were used to calculate Adjusted(3) diluted EPS.

QUARTERLY FINANCIAL HIGHLIGHTS (Fourth-Quarter 2024 vs. Fourth-Quarter 2023)

Fourth-quarter 2024 revenues totaled $17.8 billion, an increase of $3.2 billion, or 22%, compared to the prior-year quarter, reflecting an operational increase of $3.1 billion, or 21%, primarily due to a one-time, non-cash Paxlovid revenue reversal(8) of $3.5 billion recorded in fourth-quarter 2023 and, to a lesser extent, growth contributions in fourth-quarter 2024 from the legacy Seagen portfolio, the Vyndaqel family, higher Paxlovid sales year-over-year (when excluding the $3.5 billion revenue reversal(8)), higher sales in several other products across all categories, and a favorable impact of foreign exchange of $62 million (or less than 1%); partially offset by a $2.0 billion decline in Comirnaty(1) revenues. Excluding contributions from Paxlovid and Comirnaty(1), fourth-quarter 2024 revenues totaled $13.7 billion, an increase of $1.3 billion, or 11%, operationally compared with the prior-year quarter.

Fourth-quarter 2024 Comirnaty(1) revenues of $3.4 billion decreased $2.0 billion, or 38%, operationally compared with the prior-year quarter, driven primarily by fewer COVID-19 vaccinations globally as well as lower contracted doses.

Fourth-quarter 2024 Paxlovid revenues of $727 million increased $3.9 billion operationally compared with $(3.1) billion of revenues recorded in the prior-year quarter, primarily driven by the transition to traditional commercial market sales in the U.S. including a one-time, non-cash revenue reversal(8) of $3.5 billion recorded in fourth-quarter 2023.

Excluding contributions from Comirnaty(1) and Paxlovid, fourth-quarter 2024 operational revenue growth was driven primarily by:

▪Global revenues of $915 million from legacy Seagen compared with $132 million of revenue in fourth-quarter 2023 following the completion of the acquisition in mid-December 2023;

▪Vyndaqel family (Vyndaqel, Vyndamax, Vynmac) globally, up 60% operationally, driven largely by strong demand with continuing uptake in patient diagnosis, primarily in the U.S. and international developed markets, as well as increased affordability in the U.S.;

▪Eliquis globally, up 13% operationally, driven primarily by continued oral anti-coagulant adoption and market share gains in the non-valvular atrial fibrillation indication in the U.S. and certain markets in Europe, partially offset by declines due to loss of patent-based exclusivity and generic competition in certain international markets;

▪Nurtec ODT/Vydura globally, up 39% operationally, driven primarily by strong demand in the U.S. and, to a much lesser extent, recent launches in international markets, partially offset by lower net price in the U.S. due to unfavorable changes in channel mix; and

- 4 -

▪Xtandi, up 24% operationally, driven primarily by strong demand due to uptake of the non-metastatic castration-sensitive prostate cancer (nmCSPC) indication following approval in the fourth quarter of 2023 and increased affordability in the U.S.;

partially offset primarily by lower revenues for:

▪Abrysvo globally, down 62% operationally, driven primarily by a significant reduction in vaccination rates in the U.S. for the older adult indication as a result of a narrowing market opportunity given the current recommendations from the Advisory Committee on Immunization Practices (ACIP), partially offset by improved market share for the adult indication and strong demand for the maternal indication (launched in December 2023) as well as launch uptake for both indications in certain international markets;

▪Xeljanz globally, down 29% operationally, driven primarily by lower demand globally resulting from ongoing shifts in prescribing patterns related to label changes, as well as lower net price in the U.S. and the impact of regulatory exclusivity expiry in Canada; and

▪Oncology biosimilars globally, down 35% operationally, driven primarily by supply constraints in certain products, as well as both lower demand and lower net price in the U.S. and, to a lesser extent, in certain international markets.

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

Fourth-quarter 2024 Cost of Sales(2) as a percentage of revenues decreased by 18.6 percentage points compared to the prior-year quarter, driven primarily by favorable changes in sales mix as a result of significantly lower sales of Comirnaty(1), which resulted in a lower related charge for the 50% gross profit split with BioNTech and applicable royalty expenses in the quarter; and the favorable year-over-year impact related to the $3.5 billion non-cash Paxlovid revenue reversal(8) recorded in fourth-quarter 2023.

Fourth-quarter 2024 SI&A Expenses(2) decreased 7% operationally compared with the prior-year quarter, driven primarily by a decrease in marketing and promotional spend for various products, including Comirnaty(1) and Paxlovid, partially offset by an increase in spending for certain oncology and recently launched and acquired products.

Fourth-quarter 2024 R&D Expenses(2) increased 8% operationally compared with the prior-year quarter, driven primarily by a net increase in spending mainly to develop certain product candidates acquired from Seagen, as well as increased compensation-related expenses; partially offset by lower spending on certain ongoing vaccine programs and as a result of our cost realignment program.

The unfavorable period-over-period change in Other (income)/deductions—net(2) of $2.5 billion for the fourth quarter of 2024, compared with the prior-year quarter, was driven primarily by (i) lower net gains on equity securities, (ii) net periodic benefit costs associated with pension and postretirement plans incurred in the fourth quarter of 2024 versus net periodic benefit credits incurred in the fourth quarter of 2023 and (iii) higher net interest expense; partially offset by gains on the partial sale of our investment in Haleon plc (Haleon). Included in Other (income)/deductions—net(2) are total non-cash intangible asset impairment charges of $2.9 billion that were taken in the fourth quarter of 2024 due to changes in development plans and updated long-range commercial forecasts.

- 6 -

Pfizer’s effective tax rate on Reported(2) income for the fourth quarter of 2024 is primarily due to changes in the jurisdictional mix of earnings, partially offset by a tax benefit related to the Transition Tax liability under the Tax Cuts and Jobs Act of 2017.

FULL-YEAR REVENUE SUMMARY (Full-Year 2024 vs. Full-Year 2023)

Full-year 2024 revenues totaled $63.6 billion, an increase of $4.1 billion, or 7%, compared to full-year 2023, reflecting an operational increase of $4.4 billion, or 7%, partially offset by an unfavorable impact of foreign exchange of $349 million, or approximately 1%. Excluding contributions from Comirnaty(1) and Paxlovid, revenues for the full-year grew 12% operationally.

The operational revenue growth compared to the prior year was driven primarily by significantly higher global revenues for Paxlovid largely due to one-time items(8) recorded in the fourth quarter of 2023 and in 2024, the addition of legacy Seagen revenues in full-year 2024 following the acquisition in December 2023, and continued growth from the Vyndaqel family; partially offset by significantly lower revenues for Comirnaty(1).

RECENT NOTABLE DEVELOPMENTS (Since October 29, 2024)

Product Developments


Product/Project	Recent Development	Link
Braftovi (encorafenib)	February 2025. Announced positive topline results from the progression-free survival (PFS) analysis of the Phase 3 BREAKWATER study of Braftovi in combination with cetuximab (marketed as Erbitux®(9)) and mFOLFOX6 (fluorouracil, leucovorin and oxaliplatin) in patients with metastatic colorectal cancer (mCRC) harboring a BRAF V600E mutation. The trial showed a statistically significant and clinically meaningful improvement in PFS, one of its dual primary endpoints, as assessed by blinded independent central review (BICR) compared to patients receiving chemotherapy with or without bevacizumab. Further, the Braftovi combination regimen demonstrated a statistically significant and clinically meaningful improvement in overall survival (OS), a key secondary endpoint in the trial. At the time of the objective response rate (ORR) analysis, the safety profile of Braftovi in combination with cetuximab and mFOLFOX6 continued to be consistent with the known safety profile of each respective agent. No new safety signals were identified. These results will be shared with the U.S. Food and Drug Administration (FDA) to support potential conversion to full approval.	Full Release
	December 2024. Announced the FDA granted accelerated approval to Braftovi in combination with cetuximab (marketed as Erbitux®(9)) and mFOLFOX6 (fluorouracil, leucovorin, and oxaliplatin) for the treatment of patients with mCRC with a BRAF V600E mutation, as detected by an FDA-approved test. Approval was based on a statistically significant and clinically meaningful improvement in response rate and durability of response in treatment-naïve patients treated with Braftovi in combination with cetuximab and mFOLFOX6 from the Phase 3 BREAKWATER trial. Continued approval for this indication is contingent upon verification of clinical benefit. Data from the Phase 3 BREAKWATER trial was recently presented at the 2025 American Society of Clinical Oncology Gastrointestinal Cancer Symposium (ASCO GI) and were simultaneously published in Nature Medicine.

Hympavzi (marstacimab-hncq)	November 2024. Announced the European Commission (EC) granted marketing authorization for Hympavzi for the routine prophylaxis of bleeding episodes in adults and adolescents 12 years and older weighing at least 35 kg with severe hemophilia A (congenital factor VIII [FVIII] deficiency, FVIII <1%) without FVIII inhibitors, or severe hemophilia B (congenital factor IX [FIX] deficiency, FIX <1%) without FIX inhibitors.	Full Release
Ibrance (palbociclib)	December 2024. Pfizer and Alliance Foundation Trials, LLC presented results from the Phase 3 PATINA trial demonstrating that the addition of Ibrance to current standard-of-care first-line maintenance therapy (following induction chemotherapy) resulted in statistically significant and clinically meaningful improvement in PFS by investigator assessment in patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-positive (HER2+) metastatic breast cancer (MBC). The safety and tolerability of Ibrance in the PATINA study was consistent with its known safety profile in HR+, human epidermal growth factor receptor 2-negative (HER2-) MBC; no new safety signals were identified.

sasanlimab	January 2025. Announced positive topline results from the pivotal Phase 3 CREST trial evaluating sasanlimab, an investigational anti-PD-1 monoclonal antibody (mAb), in combination with Bacillus Calmette-Guérin (BCG) as induction therapy with or without maintenance in patients with BCG-naïve, high-risk non-muscle invasive bladder cancer (NMIBC). The study met its primary endpoint of event-free survival (EFS) by investigator assessment, demonstrating a clinically meaningful and statistically significant improvement with sasanlimab in combination with BCG (induction and maintenance) as compared to BCG alone (induction and maintenance). The overall safety profile of sasanlimab in combination with BCG was generally consistent with the known profile of BCG and data reported from clinical trials with sasanlimab. The profile of sasanlimab was also generally consistent with the reported safety profile of PD-1 inhibitors.	Full Release

vepdegestrant	December 2024. Arvinas, Inc. and Pfizer presented preliminary data from the ongoing Phase 1b portion of the TACTIVE-U sub-study of vepdegestrant in combination with abemaciclib among patients with locally advanced or metastatic estrogen receptor positive (ER+)/human epidermal growth factor receptor 2 negative (HER2-) breast cancer at the 2024 San Antonio Breast Cancer Symposium (SABCS). Vepdegestrant in combination with abemaciclib demonstrated encouraging clinical activity in patients previously treated with a CDK4/6 inhibitor with safety and tolerability of the combination generally consistent with the profile of abemaciclib and what has been observed in other clinical trials of vepdegestrant; no significant drug-drug interactions were observed between vepdegestrant and abemaciclib. The findings support the ongoing Phase 2 portion of the study, which is evaluating full dose abemaciclib 150 mg twice daily (BID) in combination with vepdegestrant 200 mg once daily (QD) in post-CDK4/6 advanced breast cancer.

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/(loss) and its components and diluted EPS/(LPS)(2). 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 and the accompanying Non-GAAP Financial Measure: Adjusted Income section of this press release for a definition of each component of Adjusted income as well as other relevant information.

(4)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. 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.

(5)Pfizer does not provide guidance for 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 December 31, 2024.

▪An anticipated unfavorable 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-January 2025.

▪Guidance for Adjusted(3) diluted EPS assumes diluted weighted-average shares outstanding of approximately 5.74 billion shares, and assumes no share repurchases in 2025.

(6)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.

(7)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 fourth quarter and full year for U.S. subsidiaries reflects the three and twelve months ended on December 31, 2024 and December 31, 2023, while Pfizer’s fourth quarter and full year for subsidiaries operating outside the U.S. reflects the three and twelve months ended on November 30, 2024 and November 30, 2023.

(8)Paxlovid-specific one-time items in fourth-quarter 2023 and in 2024:

▪Fourth-quarter 2023 Paxlovid revenues included a non-cash revenue reversal of $3.5 billion, of which a portion was associated with sales recorded in 2022, related to the expected return of an estimated 6.5 million treatment courses of Emergency Use Authorization (EUA)-labeled U.S. government inventory; and

▪Full-year 2024 Paxlovid revenues include $1.2 billion from two one-time items: (i) a $771 million favorable final adjustment recorded in first-quarter 2024 to the estimated non-cash Paxlovid revenue reversal of $3.5 billion recorded in fourth-quarter 2023, reflecting 5.1 million Emergency Use Authorization (EUA)-labeled treatment courses returned by the U.S. government through February

- 12 -

29, 2024 versus the estimated 6.5 million treatment courses that were expected to be returned as of December 31, 2023; and (ii) $442 million from the fulfillment of our obligated delivery of one million treatment courses to the U.S. Strategic National Stockpile.

NOTES TO CONSOLIDATED STATEMENTS OF OPERATIONS - (UNAUDITED)

(1)The financial statements present the three and twelve months ended December 31, 2024 and December 31, 2023. Subsidiaries operating outside the U.S. are included for the three and twelve months ended November 30, 2024 and November 30, 2023.

Business development activities, including the December 2023 acquisition of Seagen Inc. (Seagen), impacted financial results in the periods presented. See Note 2 to the condensed consolidated financial statements in Pfizer’s Quarterly Report on Form 10-Q for the quarterly period ended September 29, 2024, as well as Notes 1A and 2 to the consolidated financial statements in Pfizer’s 2023 Annual Report on Form 10-K.

In the first quarter of 2024, we reclassified royalty income from Other (income)/deductions––net and began presenting Royalty revenues as a separate line item within Total revenues in our consolidated statements of operations. Prior-period amounts have been recast to conform to the current presentation.

Certain amounts in the consolidated statements of operations and associated notes may not add due to rounding. All percentages have been calculated using unrounded amounts.

(2)The amount for full-year 2024 includes (i) a $771 million favorable final adjustment recorded in the first quarter to the estimated non-cash Paxlovid revenue reversal of $3.5 billion recorded in the fourth quarter of 2023, reflecting 5.1 million Emergency Use Authorization (EUA)-labeled treatment courses returned by the U.S. government through February 29, 2024 versus the estimated 6.5 million treatment courses that were expected to be returned as of December 31, 2023 and (ii) $442 million of revenue recorded in the third quarter in connection with the creation of a U.S. Strategic National Stockpile of 1.0 million treatment courses of Paxlovid, which we supplied at no cost to the U.S. government or taxpayers. The amounts for 2023 included a non-cash revenue reversal of $3.5 billion recorded in the fourth quarter, of which a portion was associated with sales recorded in 2022, related to the expected return of an estimated 6.5 million treatment courses of EUA-labeled U.S. government inventory. See Note 13C to the condensed consolidated financial statements in Pfizer’s Quarterly Report on Form 10-Q for the quarterly period ended September 29, 2024, as well as Note 17C to the consolidated financial statements in Pfizer’s 2023 Annual Report on Form 10-K.

(3)Exclusive of amortization of intangible assets. For full-year 2023, Cost of sales included a non-cash charge of $6.2 billion for inventory write-offs and related charges ($5.0 billion for Paxlovid and $1.2 billion for Comirnaty).

(4)Restructuring charges and certain acquisition-related costs include the following:

Other (income)/deductions––net	$	2,358	$	(159)	$	4,388	$	222

(a)The increase in net interest expense in the fourth quarter of 2024 reflects (i) a decrease in interest income due to lower investment balances after completion of our $43.4 billion Seagen acquisition in December 2023 and (ii) higher interest expense driven by the remaining balance of our $8 billion of commercial paper issued from the end of November to early December 2023 as part of the financing for our acquisition of Seagen. The increase in net interest expense for full-year 2024 reflects (i) a decrease in interest income due to lower investment balances after completion of our $43.4 billion Seagen acquisition in December 2023 and (ii) higher interest expense driven by our $31 billion aggregate principal amount of senior unsecured notes issued in May 2023, as well as the remaining balance of the $8 billion of commercial paper issued from the end of November to early December 2023, both part of the financing for our acquisition of Seagen.

(b)The net gains in the fourth quarter and full-year 2024 primarily include, among other things, an unrealized gain of $1 billion related to our investment in Haleon, which is now carried at fair value. The net gains in the fourth quarter and full-year 2023 primarily included, among other things, a realized gain of $1.7 billion related to our investment in Telavant Holdings, Inc.

(c)The fourth quarter and full-year 2024 primarily include certain product liability expenses related to products discontinued and/or divested by Pfizer. The fourth quarter of 2023 primarily included certain product liability and other legal expenses related to products discontinued and/or divested by Pfizer. Full-year 2023 also included legal obligations related to pre-acquisition matters.

(d)The amount for the fourth quarter of 2024 represents, and for full-year 2024 includes, intangible asset impairment charges of $2.9 billion due to changes in development plans and updated long-range commercial forecasts, composed of: (i) $1.0 billion for B7H4V (felmetatug vedotin), an in-process research and development (IPR&D) asset, (ii) $475 million for Medrol, a finite-lived brand, (iii) $435 million for Zavzpret nasal spray developed technology rights, (iv) $400 million and $200 million for Tukysa and disitamab vedotin, respectively, IPR&D assets reflecting emerging competition, as well as (v) other developed technology rights, IPR&D and a finite-lived licensing agreement totaling $436 million which also includes de-prioritization of certain assets. Full-year 2024 also includes a $240 million intangible asset impairment charge related to IPR&D associated with a Phase 3 study for the treatment of Duchenne muscular dystrophy (DMD), which reflects unfavorable clinical trial results. The amount for the fourth quarter of 2023 represented, and for full-year 2023 included, intangible asset impairment charges of $2.8 billion, composed of: (i) $1.4 billion for etrasimod (Velsipity) IPR&D based on a change in development plans for additional indications and overall revenue expectations, (ii) $964 million for Prevnar 13 developed technology rights, due to updated commercial forecasts mainly reflecting a transition to vaccines with higher serotype coverage, as well as (iii) other IPR&D and developed technology impairments totaling $366 million, due to updated commercial forecasts mainly reflecting competitive pressures. Full-year 2023 also included intangible asset impairment charges of $248 million related to IPR&D and developed technology rights.

(e)The amounts for the fourth quarter and full-year 2024 primarily include, among other things, gains of $795 million and $945 million, respectively, on the partial sales of our investment in Haleon plc (Haleon) in March and October 2024. Full-year 2024 also includes, among other things, (i) dividend income of $272 million from our investment in ViiV Healthcare Limited (ViiV) and (ii) a charge of $420 million recorded in the third quarter related to the expected sale of one of our facilities resulting from the discontinuation of our DMD program. Full-year 2023 included, among other things, (i) dividend income of $265 million from our investment in ViiV and $211 million from our investment in Nimbus Therapeutics, LLC (Nimbus) resulting from Takeda

PFIZER INC. AND SUBSIDIARY COMPANIES

NOTES TO CONSOLIDATED STATEMENTS OF OPERATIONS - (UNAUDITED)

Pharmaceutical Company Limited’s acquisition of Nimbus’s oral, selective allosteric tyrosine kinase 2 (TYK2) inhibitor program subsidiary and (ii) a $222 million gain on the divestiture of our early-stage rare disease gene therapy portfolio to Alexion Pharma International Operations Limited, a subsidiary of AstraZeneca PLC.

(6)Our effective tax rates for income/(loss) from continuing operations were 4,220.5% and (0.4)% in the three and twelve months ended December 31, 2024, respectively, and 19.2% and (105.4)% in the three and twelve months ended December 31, 2023, respectively. The decreases in our tax benefits for the fourth quarter and full-year 2024 were primarily due to changes in the jurisdictional mix of earnings partially offset by a tax benefit related to the Transition Tax liability under the Tax Cuts and Jobs Act of 2017. The positive effective tax rate for the fourth quarter of 2024 reflects the tax benefit on a pre-tax loss and includes changes in the jurisdictional mix of earnings and the impact of the aforementioned tax benefit related to the Transition Tax liability. The positive effective tax rate for the fourth quarter of 2023 reflects the tax benefit on a pre-tax loss and included changes in the jurisdictional mix of earnings and the resolution of uncertain tax positions in various markets.

(7)For the fourth quarter of 2023, basic weighted-average shares outstanding of 5,647 million (excluding common share equivalents) were used to calculate GAAP Reported Loss per common share attributable to Pfizer Inc. common shareholders––diluted.

PFIZER INC. AND SUBSIDIARY COMPANIES

NON-GAAP FINANCIAL MEASURE: ADJUSTED INCOME

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)Since 2022, we no longer exclude any expenses for acquired IPR&D from our non-GAAP Adjusted results but we continue to exclude certain of these expenses for our financial results for annual incentive compensation purposes.

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.

See the reconciliations of certain GAAP Reported to Non-GAAP Adjusted information for the fourth quarter and full-year 2024 and 2023 below and 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 additional information.

NOTES TO REVENUES TABLE INFORMATION

(UNAUDITED)



(a)			In the first quarter of 2024, we reclassified royalty income (substantially all of which related to our Biopharma segment) from Other (income)/deductions––net and began presenting Royalty revenues as a separate line item within Total revenues in our consolidated statements of operations. Prior-period amounts have been recast to conform to the current period presentation.
(b)			Reflects alliance revenues and product revenues.
(c)			The amount for full-year 2024 includes (i) a $771 million favorable final adjustment recorded in the first quarter to the estimated non-cash revenue reversal of $3.5 billion recorded in the fourth quarter of 2023, reflecting 5.1 million EUA-labeled treatment courses returned by the U.S. government through February 29, 2024 versus the estimated 6.5 million treatment courses that were expected to be returned as of December 31, 2023 and (ii) $442 million of revenue recorded in the third quarter in connection with the creation of a U.S. Strategic National Stockpile of 1.0 million treatment courses, which we supplied at no cost to the U.S. government or taxpayers. 2023 amounts include a non-cash revenue reversal of $3.5 billion recorded in the fourth quarter, of which a portion was associated with sales recorded in 2022, related to the expected return of an estimated 6.5 million treatment courses of EUA-labeled U.S. government inventory.
(d)			Prevnar family includes revenues from Prevnar 20/Apexxnar (pediatric and adult) and Prevnar 13/Prevenar 13 (pediatric and adult).
(e)			Vyndaqel family includes global revenues from Vyndaqel, as well as revenues for Vyndamax in the U.S. and Vynmac in Japan.
(f)			In September 2024, we announced our voluntary withdrawal of all lots of Oxbryta for the treatment of sickle cell disease in all markets where it is approved. as well as the discontinuation of expanded access programs worldwide, based on the totality of clinical data that indicated at that time the overall benefit of Oxbryta no longer outweighs the risk in the approved sickle cell patient population. The data suggest an imbalance in vaso-occlusive crises and fatal events, which requires further assessment that remains ongoing.
(g)			Includes, among other Hospital products, amounts previously presented as All other Anti-infectives and Ig Portfolio.
(h)			Primarily reflects alliance revenues and royalty revenues.
(i)			Biosimilars are highly similar versions of approved and authorized biological medicines. Oncology biosimilars primarily include Retacrit, Ruxience, Zirabev, Trazimera and Nivestym.

•the risk of an impairment charge related to our intangible assets, goodwill or equity-method investments;

•the impact of, and risks and uncertainties related to, restructurings and internal reorganizations, as well as any other corporate strategic initiatives and growth strategies, and cost-reduction and productivity initiatives, including any potential future phases, each of which requires upfront costs but may fail to yield anticipated benefits and may result in unexpected costs, organizational disruption, adverse effects on employee morale, retention issues or other unintended consequences;
